Description

Grain silo and silo clearing system

Technical Field

The utility model relates to the technical field of silos, in particular to a grain silo and a silo clearing system.

Background Art

In the grain storage process, silos are key storage facilities, and the smooth flow of grain inside them is crucial to ensuring production continuity and efficiency; however, due to the diversity of grain's physical properties (such as particle size, humidity, viscosity, etc.) and silo design structures (such as inclination angle, outlet design, etc.), a series of flow obstruction problems often occur, such as grain arching, blockage, and adhesion to the silo wall to form a retention layer.

At present, there are two traditional methods for clearing blockages: one is manual clearing, that is, the operator manually pokes holes with tools to clear the blocked area, or uses heavy objects such as sledgehammers to hit the blocked area to promote grain flow. Although this method can achieve certain results in emergency situations, it is highly dependent on manual operation, which is not only inefficient, but also poses a physical burden and safety risk to the operator. At the same time, frequent mechanical impacts may also accelerate the wear and damage of the silo structure. Another common means of clearing blockages is to use air cannon technology; air cannons generate strong pulse waves by instantly releasing high-pressure compressed air, directly impacting the blocked area in the silo, trying to use the impact force to decompose grain clumps and promote the natural flow of grain under gravity. However, air cannon technology also has limitations in practical applications. When a solid arched structure is formed in the blocked area of the silo, the impact of the air cannon may not effectively break the blockage, but the concentrated pressure will cause the grain to be further compacted, aggravating the blockage.

Therefore, in view of this, the inventor proposes a grain silo and a silo cleaning system to solve the above technical problems.

Utility Model Content

One of the purposes of the utility model is to provide a grain silo to solve the problem that the discharge port of the existing silo is prone to arching and clogging when discharging grain, resulting in the silo being unable to be emptied; the second purpose is to propose a silo clearing system.

On the one hand, in order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

A grain silo comprises an inner cylinder and an outer cylinder, wherein the inner cylinder comprises a storage portion and a material discharge portion, the material discharge portion is arranged below the storage portion, and the material discharge portion is in a conical structure;

The inner cylinder of the material discharging part is provided with a movable cavity, a movable plate is sealingly and slidably connected in the movable cavity, at least two elastic members are arranged in the movable cavity, each of the elastic members is arranged in the movable cavity, and the elastic members have a tendency to drive the movable plate away from the material discharging part;

It also includes an airtight device and at least two vibration devices, wherein the airtight device can drive the movable plate to move; and the vibration device is installed on the storage part and/or the unloading part.

According to the above technical solution, by designing the unloading part into a conical structure, it is convenient to promote the natural flow of grains. The airtight device and the vibration device can work alone or in coordination, and the appropriate clearing strategy can be selected according to the actual situation of grain blockage. When the grain blockage is light, it may only require a vibration device to solve it; when the blockage is serious, the combined action of the airtight device and the vibration device can more effectively clear the blockage. Through the coordinated action of the airtight device and the vibration device, the grain blockage problem can be quickly and effectively solved, and the grain arching and blockage can be avoided to facilitate warehouse clearing. It reduces the manual poking and knocking operations, and reduces the physical burden and safety risks of operators.

Further, the airtight device comprises a compressed air pump, a main air supply pipe, a first air supply pipe, a second air supply pipe and a third air supply pipe, the compressed air pump is connected to the main air supply pipe, and one end of the first air supply pipe, the second air supply pipe and the third air supply pipe are respectively connected to the main air supply pipe;

The other end of the first air supply pipe is communicated with the active chamber.

According to the above technical solution, after the compressed air pump is started, high-pressure compressed air is generated, and the compressed air is transported to the first air supply pipe, the second air supply pipe and the third air supply pipe through the main air supply pipe. One end of the first air supply pipe is connected to the main air supply pipe, and the other end is connected to the movable cavity. When the compressed air enters the movable cavity through the first air supply pipe, it pushes the movable plate to move, thereby breaking the blockage of the grain and allowing the grain to fall smoothly.

Furthermore, valves are provided on the first air supply pipe, the second air supply pipe and the third air supply pipe, and the valves are used to cut off or connect the compressed air in the first air supply pipe, the second air supply pipe and the third air supply pipe.

According to the above technical solution, the valve is used to control the circulation of compressed air in the first air supply pipe, the second air supply pipe and the third air supply pipe. In the movable cavity, the movable plate is acted upon by the elastic force of the spring. The valve adopts a pulse valve. When the pulse valve is closed and the compressed air stops supplying, the elastic force of the spring will restore the movable plate to its initial position. When the pulse valve is opened and compressed air enters the movable cavity, the movable plate will move due to the thrust of the compressed air. Due to the periodic opening and closing of the pulse valve, the movable plate will continuously vibrate under the combined action of the spring elastic force and the thrust of the compressed air. The continuous shaking of the movable plate will drive the surrounding grain particles to vibrate and displace, thereby breaking the blocking structure of the grain and allowing the grain to smoothly pass through the discharge port.

Furthermore, the vibration device includes a vibration plate, a force transmission rod and an exciter, the exciter is installed on the outer wall of the inner tube, the vibration plate is installed on the inner wall of the inner tube, one end of the force transmission rod is connected to the exciter, and one end of the force transmission rod passes through the inner tube and is connected to the vibration plate.

According to the above technical solution, the vibrator is installed on the outer wall of the inner tube and is the power source of the vibration device. When the vibrator is started, it will generate periodic vibration or impact force. The force transmission rod connects the vibrator and the vibration plate to transmit vibration. The vibration device can directly act on the grain particles, destroy the blocking structure through vibration, and achieve efficient dredging. Compared with other dredging methods in the prior art, vibration dredging has faster speed and better effect.

Further, the vibration plate includes a vibration lining plate and a vibration fin plate, the number of the vibration fin plates is multiple, and each of the vibration fin plates is mounted on the vibration lining plate;

Each of the vibration lining plates is connected to the vibration exciter correspondingly arranged on the outer side surface of the inner tube.

According to the above technical solution, the vibration lining, as the main part of the vibration plate, is directly connected to the exciter, and the vibration generated by the exciter is transmitted to the entire vibration plate through the vibration lining; the vibration fins are multiple small components installed on the vibration lining, and their design is intended to enhance the vibration effect and expand the vibration area. When the vibration lining is vibrated by the exciter, the vibration fins will also vibrate and transmit the vibration energy more widely to the grain particles in contact with it. The grain particles begin to vibrate under the joint action of the vibration fins and the vibration lining. This vibration destroys the internal friction and aggregation force between the grain particles, making the grain particles unstable. At the same time, the vibration also promotes the relative movement between the grain particles, thereby breaking the blockage structure and allowing the grain to flow smoothly.

Furthermore, the angle between the plane where the vibration lining plate is located and the plane where the vibration fin plate is located is a, wherein the value range of a is 3.5°-26.5°.

According to the above technical solution, the angle design can accelerate the flow speed of grain particles without causing flow obstruction to the grain, thereby improving the dredging efficiency and shortening the time for clearing the warehouse.

Furthermore, an air storage tank is provided inside the movable plate, and the air storage tank is connected to the second air supply pipe;

A plurality of air blowing holes are provided on one side of the movable plate, and each of the air blowing holes is communicated with the air storage tank.

Furthermore, a partition cavity is formed between the inner cylinder and the outer cylinder, and each of the exciters is respectively arranged in the partition cavity.

According to the above technical solution, the second air supply pipe provides a stable gas source for the air storage tank. The gas can be compressed air, inert gas or other gases selected according to application requirements. The air storage tank serves as a temporary storage space for the gas. When the gas enters the blowing hole from the air storage tank, multiple airflows are formed to act on the grain or the inner wall area of the inner cylinder, promoting the relative movement between the grain particles, thereby breaking the blockage.

Furthermore, a compressed air hole is provided at the bottom end of the unloading portion, and the compressed air hole is connected to the third air supply pipe.

According to the above technical solution, in some cases, grains may get stuck at the discharge port at the bottom of the inner cylinder due to their shape, size or humidity. The design of the compressed air holes can provide high-pressure airflow to the lower material section regularly or on demand. These airflows can effectively blow away or disperse materials that may be accumulated or blocked in the lower material section, helping to keep the discharge channel unobstructed and ensure that the grain can flow out smoothly.

On the other hand, the utility model also proposes a warehouse cleaning system, including a conveying structure and a grain silo as mentioned above, wherein the grain silo is installed above the conveying structure.

Beneficial effects of the utility model:

The utility model can quickly and effectively solve the problem of grain blockage by combining the coordinated work of the airtight device and the vibration device through the design of the conical feeding part. The airtight device pushes the movable plate through pulse compressed air, and the strong vibration of the vibration device can quickly break the grain blockage structure, allowing the grain to fall smoothly and improving the warehouse cleaning efficiency.

The airtight device can be used alone or in combination with different air supply pipelines for unblocking, while the vibration device adapts to different grain flow characteristics by designing specific vibration liners and vibration fins. This flexibility enables the system to cope with a variety of complex blockage situations, ensuring smooth grain circulation, reducing the need for manual intervention, reducing high-risk operations such as manual poking and knocking, and improving operational safety.

DETAILED DESCRIPTION

The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

The present embodiment proposes a grain silo, as shown in Figures 1 to 9, comprising an inner tube 1 and an outer tube 2, with a compartment 7 formed between the inner tube 1 and the outer tube 2. Grain is susceptible to moisture during storage, leading to mildew and quality degradation, and the provision of the compartment 7 can isolate the intrusion of external moisture to a certain extent, maintain a dry environment inside the silo, and thus protect the grain from moisture. When it is necessary to control the internal temperature of the silo (such as using mechanical refrigeration or heating equipment), the insulation effect of the compartment 7 can reduce energy consumption, reduce operating costs, and also help reduce greenhouse gas emissions caused by temperature fluctuations.

As shown in Figures 2 and 3, the inner cylinder 1 includes a storage portion 11 and a discharge portion 12. The discharge portion 12 is arranged below the storage portion 11, and the discharge portion 12 is a conical structure; the inner cylinder 1 of the discharge portion 12 is provided with an active cavity 121, and a movable plate 3 is sealed and slidably connected in the active cavity 121, and at least two elastic members 4 are arranged in the active cavity 121, and each elastic member 4 is arranged in the active cavity 121; in this embodiment, the elastic member 4 is preferably a compression spring.

It also includes an airtight device and at least two vibration devices 6. When the airtight device is inflated, it can drive the movable plate 3 to move; the vibration device 6 is installed on the storage part 11 and/or the unloading part 12. As an exemplary embodiment, the present embodiment is equipped with a vibration device 6 on both the storage part 11 and the unloading part 12; of course, in a possible embodiment, the vibration device 6 can be installed on the storage part 11 alone, or on the unloading part 12, which is not limited in the present embodiment. In the present embodiment, by designing the unloading part 12 as a conical structure, it is convenient to promote the natural flow of grain and facilitate clearing. The airtight device and the vibration device 6 can work alone or in coordination, and a suitable clearing strategy can be selected according to the actual situation of grain blockage. When the grain blockage is light, it may only require the vibration device 6 to solve it; and when the blockage is serious, the combined action of the airtight device and the vibration device 6 can more effectively clear the blockage. Through the coordinated action of the airtight device and the vibration device 6, the grain blockage problem can be quickly and effectively solved, and the grain arching and blockage can be avoided to facilitate clearing.

As a preferred embodiment, as shown in FIG2 , the airtight device includes a compressed air pump 51, a main air supply pipe 52, a first air supply pipe 53, a second air supply pipe 54 and a third air supply pipe 55. The compressed air pump 51 is connected to the main air supply pipe 52. One end of the first air supply pipe 53, the second air supply pipe 54 and the third air supply pipe 55 are respectively connected to the main air supply pipe 52; wherein, the other end of the first air supply pipe 53 is connected to the movable cavity 121; the second air supply pipe 54 can supply air to the outside through the inside of the movable plate 3 to form a local air flow disturbance, further promoting the flow and dispersion of grain. Specifically, as shown in FIG4 , an air storage tank 31 is provided inside the movable plate 3, and the air storage tank 31 is connected to the second air supply pipe 54; a plurality of air blowing holes 32 are provided on one side of the movable plate 3, and each air blowing hole 32 is connected to the air storage tank 31. The second air supply pipe 54 provides a stable gas source for the air storage tank 31, and the air storage tank 31 serves as a temporary storage space for the gas. When the gas enters the blowing hole 32 from the air storage tank 31, multiple airflows will be formed to act on the grain or the inner wall area of the inner cylinder 1, promoting the relative movement between the grain particles, thereby breaking the blockage.

In a possible implementation, the compressed air pump 51 may be replaced by an air suction pump.

In a possible implementation, the compressed air pump 51 can also be connected to a cold air pipe or a hot air pipe, and the compressed air pump 51 can deliver cold air or hot air to the secondary air supply pipe 54 to cool or dry the inside of the grain according to actual conditions. Of course, the delivered gas can be inert gas or other gas selected according to application requirements in addition to compressed air.

As shown in FIG8 , a compressed air hole 122 is provided at the bottom of the material discharge portion 12, and the compressed air hole 122 is connected to the third air supply pipe 55. In some cases, the grain may be stuck at the discharge port at the bottom of the inner cylinder 1 due to shape, size or humidity, etc. The compressed air hole 122 is designed to provide high-pressure airflow to the material discharge portion 12 through the third air supply pipe 55 regularly or as needed. These airflows can effectively blow away or disperse the materials that may be accumulated or blocked in the material discharge portion 12, which helps to keep the material discharge channel unobstructed and ensure that the grain can flow out smoothly.

It should be noted that, in this embodiment, depending on the actual situation of grain blockage, the airtight device can use the first air supply pipe 53 alone for unblocking, or it can be combined with the second air supply pipe 54 and/or the third air supply pipe 55 for a more comprehensive unblocking operation.

As a preferred embodiment, valves 56 are provided on the first air supply pipe 53, the second air supply pipe 54 and the third air supply pipe 55, and the valves 56 are preferably pulse valves. The valves 56 are used to cut off or connect the compressed air in the first air supply pipe 53, the second air supply pipe 54 and the third air supply pipe 55. The pulse valve is installed on the first air supply pipe 53, the second air supply pipe 54 and the third air supply pipe 55. Its working principle is to control the opening and closing of the valve core through the electromagnet. When the electromagnet is energized, the valve core is closed to prevent the compressed air from passing through; when the electromagnet is de-energized, the valve core is opened to allow the compressed air to pass through. The periodic opening and closing of the pulse valve can be controlled, so that the supply of compressed air is in a pulse shape.

According to the above technical solution, after the compressed air pump 51 is started, high-pressure compressed air is generated, and the compressed air is transported to the first air supply pipe 53, the second air supply pipe 54 and the third air supply pipe 55 through the main air supply pipe 52. One end of the first air supply pipe 53 is connected to the main air supply pipe 52, and the other end is connected to the active chamber 121. When the compressed air enters the active chamber 121 through the first air supply pipe 53, the movable plate 3 is pushed to move; in the active chamber 121, the movable plate 3 is acted upon by the elastic force of the spring. When the pulse valve is closed and the compressed air stops supplying, the elastic force of the spring will restore the movable plate 3 to its initial position; and when the pulse valve is opened and the compressed air enters the active chamber 121, the movable plate 3 will be moved by the thrust of the compressed air. Due to the periodic opening and closing of the pulse valve, the movable plate 3 will continuously shake under the combined action of the spring elastic force and the thrust of the compressed air. The continuous shaking of the movable plate 3 will drive the surrounding grain particles to vibrate and displace, thereby breaking the blocking structure of the grain and allowing the grain to pass smoothly through the discharge port.

As a preferred embodiment, as shown in Fig. 2, Fig. 3 and Fig. 9, the vibration device 6 includes a vibration plate 61, a force transmission rod 62 and an exciter 63. The exciter 63 is mounted on the outer wall of the inner cylinder 1, and the vibration plate 61 is mounted on the inner wall of the inner cylinder 1. One end of the force transmission rod 62 is connected to the exciter 63, and one end of the force transmission rod 62 passes through the inner cylinder 1 and is connected to the vibration plate 61. The exciter 63 is mounted on the outer wall of the inner cylinder 1 and is the power source of the vibration device 6. When the exciter 63 is started, it will generate periodic vibration or impact force. The force transmission rod 62 connects the exciter 63 and the vibration plate 61 to transmit vibration. The vibration device 6 can directly act on the grain particles, destroy the blocking structure through vibration, and cause the arched grain to collapse, thereby achieving grain arch breaking and achieving efficient dredging. Compared with other dredging methods in the prior art, vibration dredging has faster speed and better effect.

Furthermore, the vibration plate 61 includes a vibration lining plate 611 and a vibration fin plate 612. There are multiple vibration fin plates 612, and each vibration fin plate 612 is installed on the vibration lining plate 611; each vibration lining plate 611 is connected to the exciter 63 correspondingly arranged on the outer side surface of the inner tube 1. According to the above technical solution, the vibration lining 611, as the main part of the vibration plate 61, is directly connected to the exciter 63. The vibration generated by the exciter 63 is transmitted to the entire vibration plate 61 through the vibration lining 611; the vibration fins 612 are multiple small components installed on the vibration lining 611, which are designed to enhance the vibration effect and expand the vibration area. When the vibration lining 611 is vibrated by the exciter 63, the vibration fins 612 will also vibrate and transmit the vibration energy more widely to the grain particles in contact with it. The grain particles begin to vibrate under the joint action of the vibration fins 612 and the vibration lining 611. This vibration destroys the internal friction and aggregation force between the grain particles, making the grain particles unstable. At the same time, the vibration also promotes the relative movement between the grain particles, thereby breaking the blockage structure and allowing the grain to flow smoothly.

Furthermore, the angle between the plane where the vibration lining plate 611 is located and the plane where the vibration fin plate 612 is located is a, wherein the value range of a is 3.5°-26.5°. This angle design can accelerate the flow speed of grain particles during vibration while not causing flow obstruction to the grain, thereby improving the dredging efficiency and shortening the time for clearing the warehouse.

On the other hand, the utility model also proposes a warehouse cleaning system, including a conveying structure 8 and a grain silo as mentioned above, wherein the grain silo is installed above the conveying structure 8 .

Among them, the conveying structure 8 includes a conveying frame, a motor and a conveyor belt. The conveying frame is fixedly installed below the outer cylinder 2, and the motor and the conveyor belt are installed on the conveying frame. The motor is used to drive the conveyor belt to work; when the grain is cleared and transported, the grain falls onto the conveyor belt of the conveying structure 8 below, and the conveyor belt drives the grain to perform the conveying operation under the action of the motor.

The utility model can quickly and effectively solve the problem of grain blockage by designing a conical discharge part 12 in combination with the coordinated work of an airtight device and a vibration device 6. The airtight device pushes the movable plate 3 by pulse compressed air, and combined with the strong vibration of the vibration device 6, it can quickly break the grain blockage structure, so that the grain can fall smoothly, thereby improving the efficiency of clearing the warehouse; the airtight device can be used alone or in combination with different air supply pipelines for dredging, while the vibration device 6 can adapt to different grain flow characteristics by designing specific vibration liners 611 and vibration fins 612. This flexibility enables the system to cope with a variety of complex blockage situations, ensure smooth grain circulation, reduce the need for manual intervention, reduce high-risk operations such as manual poking and knocking, improve operational safety, have a compact structure, and strong practicality, and solve the problem that the discharge port of the existing silo is prone to arching and blockage when discharging grain, resulting in the silo being unable to be emptied.
