A precipitation apparatus is widely used as a device for removing foreign matter from dirty water such as civil water from various industrial sites and regenerating it into clean water. In recent years, an agglomeration reaction device for separating foreign matter from dirty water by forming a vortex has been used.

Before the filthy water flows into the coagulation reaction device, the chemicals are introduced into the chemical chamber and the mixing tank, and the fine suspended solids (suspensions) are coagulated, and the water inside the coagulation tank can be more effectively formed in the flocculation tank. A stirring device for stirring the device is provided.

In general, agitation refers to inducing mass movement in a specific direction in an arbitrary container, and is used for dilution, mixing, dissolution, reaction, and precipitation prevention of waste water. The stirrer is a mechanism for stirring and mixing liquid and liquid, liquid and solid, or powder, so that each particle exhibits the best performance by depositing an adhesive on each particle as much as possible. Various stirring devices exist depending on the purpose of agitation, liquidity (chemical composition, viscosity, specific gravity, temperature, presence of solids), tank capacity, and stirring time, depending on the type, size, rotation speed, and required power.

Usually the propeller type stirrer is used for small and medium capacity, low and medium viscosity liquid stirring (rotation speed 150 ~ 180 rpm), the paddle type stirrer is used when the size of the rotor is big and the speed is low, and the turbine type is medium Use a lot of speed.

In addition, there is a calibration stirrer installed at the center of the tank according to the installation method, and a stirrer for achieving an ideal stirring effect by an obstruction plate or an eccentric installation (vortex) and a mobile stirrer used for moving to several tanks.

The conventional agitation device for flocculation tank is a device for more efficiently forming a floc by flowing the water filled in the flocculation tank, and is configured to include a central axis of rotation to stand vertically in the flocculation tank.

Accordingly, when the central rotation shaft is rotated by the driving force of the motor, the plurality of blades allow the water in the flocculation tank to flow, thereby smoothly forming flocs in the flocculation tank.

In the case of the conventional stirrer, it is necessary to continuously drive the stirrer in order to obtain the stirring effect, there is a problem that the installation cost and maintenance cost for the drive is increased.

With reference to FIG. 1A and 1B, the structure of the powerless stirrer 100 of this invention is demonstrated.

1A shows an example of the non-powered stirrer 100 of the present invention, the non-powered stirrer 100 of the present invention includes a support 10, a coupling 20, and a mixer 30.

The support part 10 is formed to extend in one direction and is made to be installed inside the pipe. The support unit 10 is formed in a rod shape having a predetermined diameter so that the mixer unit 30, which will be described later, is rotatable.

The coupling part 20 is installed at both ends of the support part 10, and enables the support part 10 to be installed inside the pipe. 1A and 1B, there is shown an example in which the opening 23 is formed in the coupling portion 20 so that filthy water can flow. Therefore, when a plurality of pipes are connected, the plurality of pipes form a structure that can communicate with each other.

Coupling portion 20 may be coupled to the support 10 detachably. For example, the coupling part 20 may be coupled to the support part 10 by bolts or unions.

1A and 1B show an example in which the coupling part 20 is bolted to the support part 10 by a bolt 13. For this reason, the structure becomes easy to attach and detach, and it becomes easy to maintain or change the structure of the rotor blade 35, and the like.

The mixer section 30 includes a plurality of rotor blades 35 arranged radially. In addition, the mixer unit 30 may further include a body 33 rotatably installed on the support unit 10, each mixer unit 30 is rotated by the flow of dirty water so that the rotor blade 35 is Stir the contaminated water. On the other hand, a bearing may be installed inside the body 33, so that the relative rotation with the support 10 can be made easier.

In each mixer unit 30, the plurality of rotor blades 35 may be inclined by a predetermined angle with respect to the flow direction of the filthy water (ie, the direction from left to right in FIG. 1A and the extension direction of the support unit 10). However, this results in a structure in which each mixer unit 30 is easily rotated by the flow of dirty water. 1a shows a mixer section 30 with five rotor blades 35, although not explicitly shown in the figures, five rotor blades 35 in each mixer section 30 are tilted in the direction described above. Can be.

In addition, the rotor blade 35 in each mixer unit 30 is made so that the inclination angle is constant along the outer periphery of the body 33, so that the plurality of rotor blades 35 in each mixer unit 30 is circumferentially on the outer periphery of the body. It can be arranged parallel to each other along the direction. The inclined structure of the rotary blade 35 can also expect the effect of the rotary blade 35 itself to guide the flow of dirty water.

On the other hand, the adjacent mixer portion 30 is formed in the opposite direction of the plurality of rotor blades 35, the plurality of adjacent mixer portion 30 may be made to rotate in the opposite direction to each other. For this reason, the polluted water is not only stirred in one direction but is stirred in both directions. As an example, the leftmost mixer section 30 in FIG. 1A rotates forward with the support 10 as the axis of rotation, and then the mixer section 30 (second from left) rotates in the reverse direction, and then the mixer The portion 30 (third from left) rotates in the forward direction, then the mixer portion 30 (fourth from left) rotates in the reverse direction, and then the mixer portion 30 (rightmost) rotates in the forward direction. have. Due to this, the filthy water forms a flow in the forward and reverse directions while passing through each mixer section 30, and the stirring performance is further improved.

The mixer unit 30 may be formed in plural numbers so as to be spaced apart from each other along the extending direction of the support unit 10. In FIG. 1A, an example of the mixer unit 30 spaced apart from the left and right and arranged in five, left and right in FIG. 1B. An example of the mixer section 30 spaced in three directions and arranged in three is shown.

The number of mixer units 30 installed in the support unit 10 and the number of rotor blades 35 provided in the individual mixer units 30 may be changed depending on the flow rate or the flow rate. In particular, since the non-powered stirrer 100 of the present invention has a structure that is easily detachable from the pipe, it is possible to more easily change the number of the mixer unit 30 and the rotor blade 35.

On the other hand, according to another example of the non-powered stirrer 200 of the present invention, the non-powered stirrer 200 of the present invention may further include a pipe (40). FIG. 1B shows another example of the non-powered stirrer 200. Compared with FIG. 1A, there is a difference only in that the pipe 40 is further included, which will be described with emphasis.

Referring to FIG. 2B, coupling portions 20 are inserted at both ends of the pipe 40, and the fluid may be accommodated in the pipe 40. In addition, coupling flanges 45 having coupling holes 45a may be formed at both ends of the pipe 40 to couple the pipes 40 to each other.

In addition, an inlet 48 is formed at an outer circumference of the pipe 40, and a neutralizer, a coagulant, or a polymer coagulant may be introduced into the pipe 40 through the inlet 48. Inside the pipe 40 it is possible to configure a reaction tank that enables the aggregation and the substances introduced through the water and the inlet.

On the other hand, although the aggregation reaction apparatus 1000 of this invention is shown by FIG. 2A and 2B, the structure of the aggregation reaction apparatus 1000 is demonstrated below.

It may be installed in the 310, may be installed in only a part of the first pipe (310). The first pipe 310 is provided with an inlet opening (310a, shown in Figure 2b), to allow the external dirty water to be introduced into the first pipe (310). Inflow of external waste water may be introduced by the submersible pump, which causes a flow to rotate the mixer of the non-powered stirrer 100 inside the first pipe 310. The non-powered stirrer 100 installed in the first pipe 310 is an example device described in FIG. 1A, and it can be understood that the non-powered agitator 100 is installed in the first pipe 310 by the coupling relationship described in FIG. 1B.

As shown in FIG. 2B, at least one of the neutralizer inlet pipe 318a, the coagulant inlet pipe 318b, and the polymer coagulant inlet pipe 318c may be installed in the first pipe 310. The neutralizing agent inlet tube 318a, the coagulant inlet tube 318b, and the polymer coagulant inlet tube 318c introduce the neutralizing agent, the coagulant, and the polymer coagulant, respectively. In one example, the neutralizing agent may be caustic soda, sodium carbonate, slaked lime or limestone, the flocculant may be aluminum sulfate or ferric chloride, and the polymeric flocculant may be a polymer.

In the inside of the first pipe 310, the waste water is aggregated with a neutralizer or a flocculant to form a floc, and the first pipe 310 functions as a reaction tank.

The second pipe 320 is installed between each of the plurality of first pipes 310 to connect the first pipes 310. As a result, the first pipes 310 are in communication with each other. For example, the second pipe 320 is formed in a curved shape, and forms a pipe structure that is disposed in a winding shape together with the first pipe 310. In addition, the first and second pipes 310 and 320 communicate with each other to function as a water supply unit capable of introducing contaminated effluent water into the sedimentation separator 400.

The precipitation separator 400 receives the reaction and agglomerated contaminated water in the first pipe 310 and rotates the precipitate to precipitate and separate the flocs to discharge the clean water to the outside. In one example, the sedimentation separator 400 may be provided with an inlet pipe 316 having an inlet 316a, the inlet pipe 316 is also in communication with the first pipe 310, the first pipe 310 The reacted and agglomerated contaminated water at allows the inflow into the precipitation separator 400.

Sewage water provided to the sedimentation separator 400 is agglomerated by the non-powered stirrer inside the first pipe 310.

In addition, as described above, the mixer unit 30 may be installed on the support unit 10 so as to be rotatable by the flow of fluid (hydraulic power of raw water) to coarsen the floc.

The body portion 440 may be, for example, a cylindrical tank. The high speed nozzle 445 (shown in FIG. 4A) may be connected to the upper outer circumferential surface of the body portion 440, and the high speed nozzle 445 is connected to the outer circumferential surface of the body portion 440 along the tangential direction. When filthy water enters the body portion 440 through the 445, the swirl flow is generated inside the body portion 440.

 And, the lower portion of the body portion 440 is formed with a funnel-shaped floc removal portion 450 that gradually decreases in diameter toward the lower side, the floc is precipitated by the swirl flow generated in the body portion 440 When the flocks are accumulated in the floc removing part 450, the flocs accumulated through the floc discharge part 452 are discharged to the outside. In addition, the floc removing unit 450 is formed to form the bottom of the sedimentation separator 400 is accommodated from the filthy water flowing from the outside.

In addition, the precipitation separator 400 may include a drain pipe 410 and the precipitation guide portion 420.

 The drain pipe part 410 may be a hollow pipe upright in the vertical direction. The precipitation guide part 420 and the guide skirt 430 are fixedly supported on the outer circumferential surface of the drain pipe part 410. On the outer circumference of the drain pipe part 410 between the sedimentation guide part 420, the distribution hole 413 which introduces dirty water into the drain pipe part 410 is formed.

Hereinafter, with reference to FIGS. 4A-4C, the flow of the fluid from which dirty water flows into the flocculation reaction apparatus 1000 of this invention, foreign substances, such as a floc, is isolate | separated and clean water is discharged is described.

4A illustrates an example in which dirty water condensed in the first pipe 310 is introduced into the sedimentation separator 400 through the high speed nozzle and discharged into the clean water.

As illustrated in FIG. 4B, the flocculation reaction apparatus 1000 having the above-described configuration flows in the first pipe 310 through the inlet 310a. Although not shown in the drawings, the inflow of the waste water may be made by an underwater pump, and thus, the flow occurs in the first pipe 310.

In the first pipe 310, the non-powered stirrer 100 is rotated by the flow of muddy water, the mixer 30 is rotated and the muddy water is stirred without depending on a separate power. 4B shows an example in which the tainted water moves by forming a rotating flow in the forward and reverse directions by each of the non-powered stirrers 100.

For example, as the injected chemical, a polymer is introduced into a polymer flocculant, and the soil and suspending substances contained in the effluent react with the chemical to induce flocculation of foreign substances and coarse the particles to form flocs.

 Thereafter, the filthy water passing through the first pipe 310 and the second pipe 320 is introduced into the body 440 through the high speed nozzle 445 of the body 440 (see FIG. 4A). ), In the body portion 440, the tainted water forms a swirl flow. For this reason, the floc contained in the wastewater is settled in the lower center of the body portion 440 and is discharged to the outside of the body portion 440 through the floc removal portion 450.

 As such, the wastewater rotating through the swirl flow formed in the body portion 440 is drained through the distribution hole 413 through a gap between the settling guide portion 420 formed in the sedimentation separator 400. ) Is introduced into the inside of the body and is discharged to the outside of the body portion 440 through the outlet 443a.

 At this time, in the upper side of the sedimentation guide unit 420, while the swirl flow of the contaminated water is drastically reduced, the floc contained in the contaminated water rolls off the upper side of the sedimentation guide unit 420, and the above-mentioned floc removal unit ( 450 is settled, and the floc is also settled in the floc removal unit 450 through the settling outlet hole 411 in the drain pipe portion 410. In FIG. 4C, an example in which flocs are deposited is represented by a downward dotted arrow 630 and is stacked on the floc removal unit 450.

 As the swirl flow is separated by the surface load ratio and the dynamic separation by the swirl flow simultaneously, the grown flocs fall down and the fluid gradually rises toward the drain pipe portion 410 while forming a laminar flow. It is possible to further improve the sedimentation effect.

 Therefore, the flocculation reaction apparatus 1000 of the present invention adds the guide skirt 430 including the skirt sidewall 431 to surround the precipitation guide portion 420, thereby optimizing the optimal swirl flow to settle the floc from the filthy water. By generating a, it has an excellent advantage that can maximize the filtration efficiency for the sewage water.
