Description

A dredging system

Technical Field

The invention relates to the technical field of pipeline desilting, and in particular to a desilting system.

Background Art

Sewer desilting, daily river maintenance, ship channel expansion and "land reclamation" and other scenarios all require the cleaning of silt. The current silt cleaning work has many problems that need to be solved.

For example, sewer desilting is a key area of work for the sanitation department. In this key operation, the sanitation department has accumulated a variety of methods and different applicable tools based on its long-term work experience, which are applied to the different challenges of this work. With the continuous and rapid development of society, the high-quality and rapid construction of cities, and the requirements of the labor force formed in this context, compared with the working environment, it is inevitable that the relatively backward working conditions and tools will be optimized to adapt to the rapid development of the city, and the innovation needs that should be matched with it.

The normal operation of this project is of great importance to the normal operation of the city. Especially when there is a sudden attack of heavy rain in the rainy season, if there is a problem and it cannot be cleared in time, it may cause water accumulation to varying degrees, forming different degrees of road waterlogging, regional waterlogging and even urban waterlogging. It will hinder or even block traffic, disturb people's normal work and cause inconvenience in life.

At certain times of this season, due to the influence of various factors, some of the above-mentioned conditions are caused. Sometimes, there are also situations in some areas where emergency response is not possible. The inability to deal with emergencies does not represent the deployment capacity of work here. In the process of rapid urban development, the upgrading and transformation of some regional underground pipelines has different degrees of lag compared with the relative rapid development of the city. In the process of time, it is inevitable to focus on the tendency of emphasis. Another thing is that it is limited to tools and equipment, which cannot provide a relatively high degree of response. As a result, the objective reality based on the latter requires that it should not be limited.

The other is to promote humanized, scientific and reasonable scheduling, which can support caring for front-line workers from a practical level on the basis of tool optimization. Based on this, if a technical theory that is more in line with the requirements of the times is mastered by manufacturers who produce tools for the sanitation department, it can be transformed into actual production and produce products needed to cope with different conditions. Based on this, the escalation of waterlogging can be effectively resolved. When heavy rains come during the rainy season, the inconveniences that plague the masses will also be efficiently alleviated in time. In this way, while blocking the accumulation of waterlogging into disasters, under the support of the existing conditions, workers who are struggling on the front line of sudden waterlogging will not have to work too hard.

In theory, siltation appears as waterlogging when heavy rain falls, which is largely due to the continuous accumulation of micro-siltation over a long period of time. This is not due to negligence in daily work, but the depth is limited by the conditions that should be available. Daily cleaning and care are the normal work of the sanitation department in this field. The scientific requirements of normalization will involve different levels, and the most prominent one is mutual support. Mutual support cannot be separated from the availability of conditions, because the availability conditions are the basis for its generation. Under the premise of availability, for example, the savings in daily costs should be supported by optimizing relatively cumbersome and inefficient expenses, while the cumbersome and inefficient optimization should be compensated by the effectiveness of improving efficiency. In other words; support productivity, maximize productivity, and rise to the natural optimization of personnel configuration.

Based on this, it is necessary to provide a relatively reasonable dredging system.

Summary of the invention

Based on this, the purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art and provide a dredging system.

A dredging system comprising

A probe device, the probe device comprising a suction lift component and a lift component; the suction lift component is used to suck in silt and sewage, and the lift component is used to return the sewage that has been treated by differentiation and filtration;

A differentiation treatment device, the differentiation treatment device is used to perform differentiation and filtration treatment on the sludge and sewage sucked by the suction component;

A driving device, the driving device includes a suction water pump and a lift water pump; the input end of the suction water pump is connected to the output end of the suction assembly, and the output end of the suction water pump is connected to the input end of the differentiation treatment device; the input end of the lift water pump is connected to the output end of the differentiation treatment device, and the output end of the lift water pump is connected to the input end of the lift assembly.

The desilting system of the present invention goes deep into the sewer through the probe device to clean up the silt and dirt. The cleaned silt is transported to the differentiation treatment device on the ground through the pipeline; after differentiation, the treated sewage is returned to the sewer through the pipeline. In this process, the silt is filtered and intercepted, and retained in the space to be further treated. When the treatment degree is reached, it will be automatically processed to the final treatment room. After the entire operation is completed, the staff will transport it to the centralized disposal site for disposal.

The suction pump and the lift pump adopt different power pumps according to the needs. The series combination of the two pump bodies of the suction pump and the lift pump is to avoid placing the operating state of the suction component and the lift component at the same frequency under the same tendency. Because if the frequency is the same, the separation during the operation will cause the pressure-oriented resistance and the terminal pressure that should be possessed to a certain extent based on the effect, and the relative balance interval maintained with it will be quickly broken in time. While breaking, the effect cannot be achieved. This is because the relative comparison of the pressures of the two will continue to change due to the effect of the effect during the separation process. If the frequency is the same, the required pressure and the terminal pressure will continue to amplify the contradiction during the operation, thereby interrupting the operation of the system. Because the work progress accumulates with time, the separation of silt continues to increase, the resistance formed will continue to amplify, and the pressure directly associated with it will also increase. However, the normal pressure at the end required by the probe device will be affected and relatively reduced. As a result, the ability to work efficiently will be quickly lost during the operation of the system. If high-frequency conversion is adopted to separate substances, in addition to the need to increase the cost of the corresponding components, it is difficult to fundamentally solve the new problems that arise. Because no matter how high the frequency is, it must be based on effectiveness, and the size of the effectiveness is proportional to the size of the contradiction. In addition, when the urgency of the contradiction is alleviated, the frequency of instability will increase. Because this frequency will correspond to the frequency of conversion. It is not difficult to imagine that when the normal working state is placed on high-frequency oscillation, the durability of the system structure will undoubtedly be damaged. Therefore, the combination of double pumps in series not only reduces costs, but also solves the problem of the suction component and the lift component working at the same frequency.

In addition, due to the different functions of the sewers, the actual size of the structure and the pipe width of the size will also be different. In the overall desilting system and the support setting, the size and width must be set according to the actual needs. In other words, in order to have a complete working configuration in this field, different models are needed to support it.

In addition to being used in sewer dredging work, the dredging system of the present invention can also be used in daily river care, ship channel expansion and "land reclamation" and other situations where silt blockages need to be cleared.

Furthermore, it also includes

A balanced distribution box, wherein a one-way valve is provided in the balanced distribution box, and an input end of the balanced distribution box is connected to an output end of the differentiation processing device; the balanced distribution box is provided with a first output end and a second output end; and the first output end of the balanced distribution box is connected to an input end of the lift water pump;

A pressure balance pipe, wherein the second output end of the balance distribution box is connected to the input end of the pressure balance pipe;

An automatic pressure balancing one-way valve, the input end of which is connected to the output end of the pressure balancing pipe;

A lift path connection box is provided with a first input end and a second input end, the first input end of the lift path connection box is connected to the output end of the automatic pressure balancing one-way valve; the second input end of the lift path connection box and the output end of the lift path connection box are connected to the lift assembly.

The beneficial effect of adopting the above further scheme is that the working state under the dual pump setting will also have unstable factors in the process of normal working. The two factors presented under the dual pump setting are that the pressure formation will be greater than the required support capacity, and the other is that when the terminal pressure is combined with the series connection, in addition to the excess of the former phenomenon, it will also be insufficient over time. The above unstable factors can be solved by setting a pressure balance pipe and a pressure automatic balance check valve. For example, when supply exceeds demand, the pressure balance pipe will automatically intercept the excess pressure, and the pressure balance pipe will be set to pass the lift pump and directly spray out through the output end of the lift assembly. The function of the pressure automatic balance check valve is to establish a connection without hindering the excess pressure, and prevent the lift pump from digesting normally and causing the digestion results to flow back. When the pressure automatic balance check valve is in a closed state, the normal operation state of the system is in a negative pressure state. This negative pressure state will continue to escalate with the accumulation of time, because with the accumulation of time, the results will be greater, and the greater the results, the greater the degree of negative pressure. With the assistance of the lift pump, the negative pressure generated continues to increase until the lift pump can no longer function normally. The spaces connected by the two pumps will reach a certain negative pressure. When this negative pressure reaches a certain level, the pressure automatic balance check valve will be opened. When the pressure relief device is opened, the harvest waiting device will also be opened, and the harvest will be transferred to the processing storage box.

Furthermore, the input end of the suction assembly and the output end of the lift assembly together form a probe portion, and the probe portion can be placed in a pipeline to clean up silt.

The beneficial effect of adopting the above further scheme is that the input end of the suction assembly and the output end of the lift assembly together form a probe part, which can return the treated sewage through the loop pipe to the probe device for discharge, thereby simplifying the system structure, making the structure compact, and saving the space occupied by the system.

Furthermore, the suction lift component comprises

A suction channel, the input end of the suction channel is the input end of the suction component; the output end of the suction channel is connected to the input end of the suction water pump;

A suction check valve, wherein the suction check valve is arranged in the suction passage;

The lift assembly comprises

A discharge box, wherein a one-way valve is provided in the discharge box; the input end of the discharge box is connected to the output end of the lift water pump;

A lift transition path pipe, the input end of which is connected to the output end of the discharge box; the output end of which is connected to the second input end of the lift path connection box;

A lift shunt box, the input end of which is connected to the output end of the lift path connection box;

A plurality of lift shunt pipes, the lift shunt box is evenly provided with a plurality of output ends, and the input end of each lift shunt pipe is connected to the output end of each lift shunt box;

A flow divider hood is sleeved outside the input end of the suction channel, the flow divider hood is evenly provided with a plurality of input ends, the output end of each lift diverter pipe is connected to the input end of each flow divider hood; the output end opening of the flow divider hood and the input end opening of the suction channel are arranged in the same direction and correspond to each other, a flow divider plate is provided between the output end opening of the flow divider hood and the input end opening of the suction channel, and a plurality of through holes are evenly provided on the flow divider plate; the output end of the flow divider hood and the input end of the suction channel together constitute a probe part.

The beneficial effect of adopting the above further scheme is that the treated sewage is returned to the probe part by the loop pipe for discharge, so that the effectiveness of the operation will also be improved. Because the efficiency of the probe will be different from the ideal effectiveness if it relies solely on the suction, pressure and cohesion of the probe. The factor causing this phenomenon is that the properties of the combination of clogging materials are diversified. Based on the existence of such a combination, there is a certain difference in relative density, and the accumulated relatively loose structure only relies on the singleness of suction and pulling to catalyze the solidity of the clogging materials to a certain extent. The effectiveness of the principle is relatively ideal. Based on this, under normal circumstances, additional equipment will generally be adopted in the solution. If it is limited to the level of addition, the extension formed by this will not only add unnecessary burden to the probe and bring a certain degree of inconvenience to the normal operation of the probe, but also directly raise the cost, limiting the prospect of widespread application. Therefore, based on comprehensive considerations, there is no need to add additional auxiliary machinery to meet the needs of different levels. By connecting the treated sewage to the lift diversion box through a pipeline, and connecting the diversion pipeline of the lift diversion box to the lift diversion pipe and diversion plate, the jet discharged from it will touch the clotted clots and break up the solidified clots. Because the impact force of the jet is not enough to counteract the coagulation degree formed by the clotting over time.

When the clotted solids are dispersed by the high-pressure water flow, under the action of the suction force, those that are located in the inner periphery of the probe and are not isolated by the impact force will flock to the direction of the suction force. Because the spatial properties of the force guidance are based on the isolation of the surrounding environment, the natural path is also limited.

Furthermore, the suction lift component also includes

An impeller support, the impeller support being arranged in an input end opening of the suction channel;

A suction impeller is rotatably arranged on the impeller bracket and is located at the center of the input end opening of the suction channel.

The beneficial effect of adopting the above further scheme is that, by setting up a suction impeller, the silt particles that are dispersed are prevented from being sucked away during the swinging process because of the difference in mass density and the relatively large gravity counterbalance ratio. Because of the difference in density, the buoyancy is also different, and the relative gravity counterbalance ratio is also different. When the suction force acts on the suction impeller, due to the orientation angle of the impeller blades, when the swayed silt particles cross the blades in the state of motion and rotation, the conditions for the silt particles to sink by gravity will be shielded under the rotation of the blade amplitude. Therefore, silt particles with relatively large density will not be dominated by gravity and sink again before being absorbed into the pipeline after being swung up when the gravity is too large and the buoyancy is too small.

Furthermore, it also includes:

A transition distribution box, wherein the input end of the transition distribution box is connected to the output end of the lift water pump; the output end of the transition distribution box is connected to the input end of the discharge box;

A plurality of guide and power tubes, the input ends of which are connected to the transition distribution box; each guide and power tube is provided with a guide power switch;

A walking device, the walking device can move forward and turn; the probe part is arranged on the walking device;

Two left and right guide jet pipes, the two left and right guide jet pipes are respectively arranged on both sides of the forward direction of the walking device, and the input ends of the left and right guide jet pipes are respectively connected to the output end of a guide and power pipe;

A power jet pipe is arranged corresponding to the forward direction of the walking device, and an input end of the power jet pipe is connected with an output end of a guide and power pipe.

The beneficial effect of adopting the above further scheme is that when the probe part is operating in the sewer, it needs to have a certain degree of mobility of left and right swing, as well as the basic function of forward propulsion, in order to support the coverage without dead angles during the operation. These functionalities are the support for efficiency, which is both irreplaceable and irreducible. Since mobility is irreplaceable for the basic nature of the task, and there are some limitations in various aspects of the mobility of a separate assembly, mobility can also be built by using the above-mentioned setting measures. The effectiveness that can be supported by this construction will not be inferior to the ideal level expected based on the mechanical setting. It is only necessary to add a few pipelines with a certain flow rate and set the release port to the required direction.

The mobility required during the operation is relatively an intermittent working state. Its operability is also an intermittent state based on the need. Based on the intermittent demand, different switches need to be set on the operating console to control the interception of different paths, so as to achieve the real-time needs in operation.

Furthermore, the differentiation processing device comprises

Filter box;

A filter plate, wherein the filter plate divides the filter box into a pre-filtration space and a post-filtration space; the output end of the suction water pump is connected to the water inlet space;

A partition plate, wherein the partition plate divides the filtered space into a water inlet space and a water outlet space;

A plurality of pressure balancing valves are evenly arranged on the partition plate; the input end of the pressure balancing valve is connected to the water inlet space; the output end of the pressure balancing valve is connected to the water outlet space; the input end of the lift water pump is connected to the water outlet space.

The beneficial effect of adopting the above further scheme is that by setting up a filter plate, the blockage can be effectively filtered and differentiated; the filtered sewage passes through the pressure balancing valve and then is returned to the probe part through the lift pump for discharge; by setting up a number of pressure balancing valves, the pressure balance in the filter box and the system as a whole can be maintained, thereby improving the stability of system operation.

Furthermore, the pre-filtration space is connected with a cleaning pipeline.

The beneficial effect of adopting the above further solution is that by providing a cleaning pipeline, the clogged materials in the space before filtration can be cleaned and discharged in a timely manner.

Furthermore, it also includes

A negative pressure pipeline, the input end of which is in communication with the water outlet space;

An auxiliary one-way valve, the output end of the negative pressure pipeline is connected to the input end of the auxiliary one-way valve;

A negative pressure automatic balancing start valve, the output end of which is connected to the output end of the auxiliary one-way valve;

A negative pressure display device, the input end of which is connected to the input end of the negative pressure automatic balancing start valve, and the negative pressure display device is used to display the negative pressure condition inside the differentiation treatment device.

The beneficial effect of adopting the above further scheme is that by setting up a negative pressure pipe, the filtered sewage passes through the auxiliary one-way valve and is pressed toward the negative pressure automatic balancing starting valve. The negative pressure automatic balancing starting valve can respond to the water pressure to the negative pressure display device, and intuitively display the negative pressure situation in the filter box through the negative pressure display device; the setting of the negative pressure automatic balancing starting valve and the negative pressure display device can also be replaced by devices such as a pressure gauge.

Furthermore, it also includes a water pipe for cleaning after operation and limited operation; the input end of the water pipe for cleaning after operation and limited operation is connected to the output end of the auxiliary one-way valve; and a use switch is connected to the water pipe for cleaning after operation and limited operation.

The beneficial effect of adopting the above further scheme is that by setting up water pipes for post-operation cleaning and limited operation, additional pipes can be installed according to the needs of expanded work, and the filtered sewage can be sprayed out for utilization.

For better understanding and implementation, the present invention is described in detail below with reference to the accompanying drawings.

For another example, if the requirements are higher, a radar probe is installed on the probe, and a software is written to integrate imaging, or other settings are also connected on this basis. The supply required for configuration products is currently more popular, and its cost performance is relatively cheap. It is also popular for companies to write software according to requirements. And the required software is also relatively simple. Single and comprehensive configurations will not generate too high a cost and push the price range that is generally acceptable. If the price is based on mass production, the popularization of price factors will be smaller.

The working process of this embodiment:

Driven by the suction pump 31, water and silt enter the suction channel 111 from the input end of the suction channel 111, and the water flow causes the suction impeller 113 to rotate, thereby breaking up the silt and making it easier to suck in. Then, the water and silt enter the suction pump 31, and then enter the filter box 21 from the output end of the suction pump 31 for differentiation and filtration.

The specific process of differentiation filtration is that the silt and water enter the pre-filtration space 21a. Under the blockage of the filter plate 22, the silt stays in the pre-filtration space 21a, and the water enters the water inlet space 21b. When the pressure is sufficient, the water passes through the pressure balance valve 24 and enters the water outlet space 21c, and then is discharged from the filter box 21.

Then, water is discharged from the filter box 21 and enters the balance distribution box 41. Under normal circumstances, water will enter the input end of the lift pump 32 from the balance distribution box 41, and then be discharged into the transition distribution box 51 under the drive of the lift pump 32, and then pass through the discharge box 121, the lift transition path pipe 122, the lift path connection box 44, the lift diverter box 123, the lift diverter pipe 124, the diverter cover 125 in sequence, and then be discharged from the through hole 1261 of the diverter plate 126; but the pressure of the filter box 21 is too high, exceeding the load of the lift pump 32, that is, supply exceeds demand. , after the excess water is discharged from the filter box 21, it will enter the pressure balance pipe 42 from the balance distribution box 41, and then push open the automatic pressure balance check valve 43, and then pass through the lift path connection box 44, the lift diversion box 123, the lift diversion pipe 124, and the diversion cover 125 in sequence, and then be discharged from the through hole 1261 of the diversion plate 126, so as to realize the automatic adjustment of the pressure balance in the system; when the water is sprayed out from the through hole 1261 of the diversion plate 126, it will impact the silt below it, so that the silt can be more easily sucked in from the input end of the suction channel 111;

The user can turn on the corresponding guide power switch 521 as needed, so that water flows into the corresponding guide and power tube 52 and is ejected from the corresponding left and right guide jet tubes 54 and/or power jet tubes 55, thereby moving or rotating the walking device 53 to realize the forward movement or turning of the probe part.

In addition, the user can observe the negative pressure in the filter box 21 by observing the negative pressure display device 64. The negative pressure display device 64 can also be replaced by other devices, such as a pressure gauge, etc. These other options are within the scope of protection of the present invention.

The user can also turn on the use switch 651 according to the needs of the expansion operation, so that the water in the filter box 21 is sprayed out from the post-operation cleaning and limited operation water pipe 65 for other uses.

Compared with the prior art, the present invention uses a probe device to penetrate deep into the sewer to clean up the silt and dirt. The cleaned sludge is transported to the differentiation treatment device on the ground through the pipeline; after differentiation, the treated sewage is returned to the sewer through the pipeline. In this process, the sludge is filtered and intercepted, and retained in the space to be further treated. When the treatment degree is reached, it will be automatically processed to the final treatment room. After the entire operation is completed, the staff will transport it to a centralized disposal site for disposal.

The suction pump and the lift pump adopt different power pumps according to the needs. The series combination of the two pump bodies of the suction pump and the lift pump is to avoid placing the operating state of the suction component and the lift component at the same frequency under the same tendency. Because if the frequency is the same, the separation during the operation will cause the pressure-oriented resistance and the terminal pressure that should be possessed to a certain extent based on the effect, and the relative balance interval maintained with it will be quickly broken in time. While breaking, the effect cannot be achieved. This is because the relative comparison of the pressures of the two will continue to change due to the effect of the effect during the separation process. If the frequency is the same, the required pressure and the terminal pressure will continue to amplify the contradiction during the operation, thereby interrupting the operation of the system. Because the work progress accumulates with time, the separation of silt continues to increase, the resistance formed will continue to amplify, and the pressure directly associated with it will also increase. However, the normal pressure at the end required by the probe device will be affected and relatively reduced. As a result, the ability to work efficiently will be quickly lost during the operation of the system. If high-frequency conversion is adopted to separate substances, in addition to the need to increase the cost of the corresponding components, it is difficult to fundamentally solve the new problems that arise. Because no matter how high the frequency is, it must be based on effectiveness, and the size of the effectiveness is proportional to the size of the contradiction. In addition, when the urgency of the contradiction is alleviated, the frequency of instability will increase. Because this frequency will correspond to the frequency of conversion. It is not difficult to imagine that when the normal working state is placed on high-frequency oscillation, the durability of the system structure will undoubtedly be damaged. Therefore, the combination of double pumps in series not only reduces costs, but also solves the problem of the suction component and the lift component working at the same frequency.

In addition, due to the different functions of the sewers, the actual size of the structure and the pipe width of the size will also be different. In the overall desilting system and the support setting, the size and width must be set according to the actual needs. In other words, in order to have a complete working configuration in this field, different models are needed to support it.

In addition to being used in sewer dredging work, the dredging system of the present invention can also be used in daily river care, ship channel expansion and "land reclamation" and other situations where silt blockages need to be cleared.

The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
