Description

Technical Field

[0001] This application relates to the technical field of industrial wastewater, and in particular to a mobile integrated chemical precipitation treatment device. Background Technology

[0002] In the industrial production sector, services such as metal heat exchanger cleaning generate cleaning wastewater containing high concentrations of heavy metals. With the continuous development of national industry, the scale of such services is gradually expanding, and the total amount of wastewater generated is also increasing. Environmental protection has always been a focus of social concern, and the country's emphasis on environmental protection is constantly increasing, with environmental policies becoming increasingly stringent. For companies that generate wastewater, proper wastewater treatment is not only a response to national environmental policies but also an inevitable choice for sustainable development. Effective wastewater treatment can reduce environmental pollution, protect ecological balance, and also help enhance the company's social image and competitiveness.

[0003] Traditionally, wastewater treatment for such enterprises mainly employs two models. One is to construct a civil engineering wastewater treatment plant, using large-scale civil engineering ponds and related treatment facilities to centrally treat wastewater. This method has certain advantages when treating large-scale wastewater, achieving relatively stable treatment results. The other model is to use a decentralized, on-site equipment installation approach, distributing multiple treatment devices across the production site for treatment based on the location of wastewater generation, thereby improving the timeliness of treatment.

[0004] However, these traditional wastewater treatment methods are clearly unsuitable for enterprises with highly seasonal production and small volumes of water per wash but high pollutant concentrations. For small-volume treatment needs, the construction volume of civil engineering water tanks is often much larger than the actual treatment requirements to meet structural requirements, resulting in excessively high initial investment and poor economic efficiency. Moreover, fixed treatment facilities lack flexibility and cannot adapt to the needs of seasonal production or relocation, easily leading to idle or wasted resources, thus requiring further improvement. Summary of the Invention

[0005] To address the above problems, this application provides a mobile integrated chemical precipitation treatment device.

[0006] This application provides a mobile integrated chemical precipitation treatment device, which adopts the following technical solution:

[0007] A portable integrated chemical precipitation treatment device includes an integrated frame with slots at the bottom for forklift forks; an inlet tank, at least one reaction tank, a sedimentation tank, and a wastewater treatment system sequentially arranged within the integrated frame, with each tank connected by internal piping to form a wastewater treatment flow path; a dosing system installed within the integrated frame and connected to the reaction tank via dosing piping; and an electrical control system fixedly installed within the integrated housing, electrically connected to and controlling the wastewater treatment system, the dosing system, and the pumps, agitators, and valves within each tank; the reaction tank includes a neutralization reaction tank, a mixing reaction tank, and a coagulation aid reaction tank sequentially connected, with each reaction tank equipped with a mechanical agitator controlled by the electrical control system. The sedimentation tank is equipped with a dosing point driven by a dosing system. The sedimentation tank contains a filtration mechanism, which includes a filtration assembly and a driving assembly. The filtration assembly includes a fixed filter plate fixedly connected to the inclined inner wall of the sedimentation tank and a sliding filter plate slidably connected to the fixed filter plate. Several sliding filter plates are provided in a stepped arrangement, with adjacent sliding filter plates sliding relative to each other. The driving assembly drives the sliding filter plates to move horizontally, thereby pushing the flocculants on the fixed filter plate. The outlet end of the pipe connected to the coagulation aid reaction tank faces the sliding filter plate. The fixed filter plate has a drop outlet for the flocculants to fall through. The sedimentation tank contains a collection device for collecting the flocculants falling through the drop outlet.

[0008] By adopting the above technical solution, the bottom of the integrated frame is equipped with slots for forklift forks to insert, making the device easy to move and adapting to the needs of seasonal production or relocation of enterprises, reducing resource idleness or waste. The inlet tank, reaction tank, sedimentation tank and sewage treatment system are arranged in sequence in the integrated frame and connected by built-in pipelines to form a wastewater treatment flow path. The dosing system is connected to the reaction tank through dosing pipelines. The electrical control system is electrically connected to and controls the sludge treatment system, the dosing system and the water pumps, agitators and valves in each tank, realizing the integration and automation of wastewater treatment and improving treatment efficiency.

[0009] For flocculants, existing technologies typically discharge them into a sedimentation tank for settling, then drain the water before discharging it through a sludge treatment system. This process is relatively time-consuming, and for mobile integrated treatment devices, the limited time available for placement can impact overall efficiency. Another approach involves using filtration components for filtration followed by sludge treatment. However, during operation, as flocculants accumulate, some enter the filter mesh, affecting water discharge. To address this, a stepped filter plate system is implemented. This system consists of several stepped filter plates positioned close to the sedimentation tank wall as the flocculants are discharged. As the drive assembly moves the plates away from the fixed plate, they unfold to collect the flocculants, increasing the contact area and thus improving filtration efficiency. As the drive assembly moves the push filter plate closer to the fixed filter plate, it pushes the flocs filtered onto the push filter plate and the fixed filter plate to the drop outlet for discharge. During the movement, the push filter plate cleans the upper surface of the push filter plate and the fixed filter plate, reducing the possibility of clogging.

[0010] Preferably, the filtration assembly further includes a baffle plate disposed on the push filter plate and a control component for controlling the rotation of the baffle plate to intercept water, and the outlet end of the pipeline connected to the coagulation aid reaction tank is oriented toward the push filter plate.

[0011] By adopting the above technical solution, a baffle plate is set on the push filter plate, and the baffle plate is rotated by the control component to intercept the water. The outlet end of the pipeline connected to the coagulation reaction tank faces the push filter plate. This allows the wastewater to be effectively intercepted by the baffle plate when passing through the push filter plate, prolonging the residence time of the wastewater at the filter component. This allows the flocculants in the wastewater to have more time to be filtered and settled, thereby improving the filtration effect of the filter component on the flocculants in the wastewater and improving the wastewater treatment efficiency and quality of the entire mobile integrated chemical precipitation treatment device.

[0012] Preferably, the blocking plate is rotatably connected to the pushing filter plate. The blocking plate includes a blocking section and a connecting section connected to the blocking section. A first rotating rod is fixedly inserted at the connection between the connecting section and the blocking section. The first rotating rod is rotatably connected to the pushing filter plate. The control component includes a first torsion spring coaxially sleeved on the first rotating rod. As the driving assembly drives the pushing filter plate to move away from the fixed filter plate, the first torsion spring forces the free end of the blocking section to move away from the fixed filter plate. The free end of the connecting section abuts against the upper surface of the fixed filter plate. The fixed filter plate is provided with a guide surface. As the driving assembly drives the pushing filter plate to move closer to the fixed filter plate, the free end of the connecting section drives the free end of the blocking plate to move closer to the fixed filter plate along with the guide surface.

[0013] By adopting the above technical solution, the baffle plate is rotatably connected to the push filter plate, and the baffle plate consists of a blocking section and a connecting section. The first rotating rod at the connection point of the two is rotatably connected to the push filter plate. With the cooperation of the first torsion spring coaxially sleeved on the first rotating rod, when the drive component drives the push filter plate to move away from the fixed filter plate, the first torsion spring will force the free end of the blocking section to move away from the fixed filter plate, so as to be tilted upward, thereby intercepting water and improving the filtration effect. The guide surface of the fixed filter plate allows the free end of the connecting section to move along the guide surface to drive the free end of the baffle plate to move closer to the fixed filter plate when the drive component drives the push filter plate to move closer to the fixed filter plate. This facilitates the push filter plate to push and clean the flocs on the fixed filter plate, improving the overall processing performance and efficiency of the device.

[0014] Preferably, a plurality of filter components are arranged at intervals along the height direction of the sedimentation tank, and the filter holes on the pushing filter plate and the fixed filter plate are arranged to gradually decrease towards the bottom wall of the sedimentation tank, and the number of collection elements corresponds to the number of filter components.

[0015] By adopting the above technical solution, several filter components are arranged at intervals along the height of the sedimentation tank, which can filter wastewater multiple times at different heights to improve the filtration effect; the filter holes on the pushing filter plate and the fixed filter plate gradually decrease towards the bottom wall of the sedimentation tank, which can perform graded filtration according to the sedimentation of wastewater impurities, further improving the filtration accuracy; the number of collection components is set to correspond to the number of filter components, which can effectively collect the flocculent material filtered by each filter component, which is convenient for subsequent treatment.

[0016] Preferably, the driving assembly includes a moving component that reciprocates horizontally with the driving plate and the driving plate. The driving plate is fixed to the end of the pushing filter plate away from the fixed filter plate. Several filter components are staggered on both sides of the driving plate. The driving plate is provided with several water outlet troughs at intervals along its height direction, corresponding to the filter components. A telescopic guide plate is provided below the filter components. The upper end of the guide plate is located on the side of the drop outlet away from the sedimentation tank, and the lower end of the guide plate is connected to the water outlet trough.

[0017] By adopting the above technical solution and by setting up guide plates that are staggered, the utilization rate of space can be improved, thereby further reducing the size of the sedimentation tank and the overall size of the sedimentation treatment device, and improving the adaptability of the treatment device.

[0018] Preferably, the sedimentation tank is further provided with a cleaning component for cleaning the push filter plate closest to the drive plate. The cleaning component includes a nozzle disposed on the drive plate and a water conveying component connected to the nozzle.

[0019] By adopting the above technical solution, a cleaning component is installed in the sedimentation tank. Using the nozzles on the drive plate and the water supply components connected to the nozzles, the push filter plate closest to the drive plate can be cleaned. This can promptly remove impurities and flocculents attached to the push filter plate, reducing their accumulation and affecting the filtration effect and service life of the push filter plate. This ensures that the push filter plate can continuously and efficiently filter wastewater, thereby improving the wastewater treatment efficiency and quality of the entire mobile integrated chemical precipitation treatment device.

[0020] Preferably, the drive plate is provided with a control component for adjusting the angle between the nozzle and the drive plate, so as to control the spray angle of the nozzle.

[0021] By adopting the above technical solution, a control component for adjusting the angle between the nozzle and the drive plate is set on the drive plate. The spray angle of the nozzle can be flexibly changed according to actual needs, thereby accurately controlling the spray distance of the nozzle. This allows for effective cleaning of the filter plate at different locations and ranges, improving cleaning effect and efficiency, and ensuring the normal operation and good filtration performance of the filter components in the sedimentation tank.

[0022] Preferably, a second rotating rod is rotatably connected to the drive plate, and a water supply pipe is connected to the second rotating rod. The water supply pipe is connected to the nozzle. The control component includes a second torsion spring coaxially sleeved and fixed with the second rotating rod, a gear fixedly sleeved on the second rotating rod, and a rack meshing with the gear. The rack is fixedly connected to the inner wall of the sedimentation tank.

[0023] By adopting the above technical solution, during the movement of the drive plate, the rack is fixed to the inner wall of the sedimentation tank and meshes with the gear. The gear drives the second rotating rod fixed thereto to rotate, and at the same time, the second torsion spring, which is coaxially sleeved and fixed to the second rotating rod, deforms. The rotation of the second rotating rod will drive the water supply pipe connected to it to rotate, which in turn causes the nozzle connected to the water supply pipe to rotate, realizing the adjustment of the nozzle angle. This allows for control of the nozzle's spray distance, enabling more precise and effective cleaning of the filter plate closest to the drive plate according to different cleaning needs, thus improving the cleaning effect and the practicality of the device.

[0024] Preferably, the upper surface of the pushing filter plate is inclined downward toward the fixed filter plate.

[0025] By adopting the above technical solutions, the possibility of flocculent accumulation on the filter plate can be reduced.

[0026] Preferably, the number of the baffles corresponds to the number of the push filter plates.

[0027] By adopting the above technical solutions, the sedimentation and filtration time of flocculants can be improved.

[0028] In summary, this application has the following beneficial effects:

[0029] 1. The integrated frame has slots at the bottom for easy forklift handling, and its mobility allows it to meet the needs of seasonal production or relocation, avoiding idle and wasteful resources.

[0030] 2. Each tank is connected by built-in pipelines to form a wastewater treatment flow path. The dosing system is connected to the reaction tank, and the electrical control system controls each component to realize automated wastewater treatment and improve treatment efficiency.

[0031] 3. The filtration mechanism in the sedimentation tank can push the flocs on the fixed filter plate to fall and collect them, effectively separating the flocs and improving the wastewater treatment effect. Attached Figure Description

Detailed Implementation

[0044] The following is in conjunction with the appendix Figure 1 - Appendix Figure 11 This application will be described in further detail below.

[0045] This application discloses a mobile integrated chemical precipitation treatment device.

[0046] Example 1:

[0047] A portable integrated chemical precipitation treatment device, referring to Figure 1 The system includes an integrated frame 1, an inlet tank 11, a reaction tank 12, a sedimentation tank 13, a wastewater treatment system 14, a dosing system 15, and an electrical control system (not shown in the figure). The inlet tank 11, reaction tank 12, sedimentation tank 13, and wastewater treatment system 14 are sequentially arranged within the integrated frame 1. Each tank is connected by built-in pipelines to form a wastewater treatment flow path. The dosing system 15 is installed within the integrated frame 1 and connected to the reaction tank 12 via dosing pipelines. The electrical control system is fixedly installed within the integrated frame 1 and electrically connects to and controls the wastewater treatment system 14, the dosing system 15, and the pumps, agitators, and valves within each tank, achieving the effect of flexible mobility and effective wastewater treatment.

[0048] The integrated frame 1 features a slot at its bottom for forklift forks to insert, facilitating overall movement and operation and adapting to seasonal production and relocation needs. The integrated frame 1 can be constructed from high-strength steel to ensure structural strength and stability, or from aluminum alloy, which is lightweight and corrosion-resistant. The slot is an opening at the bottom of the frame, allowing for easy insertion of forklift forks.

[0049] The reaction tank 12 includes a neutralization reaction tank 121, a mixing reaction tank 122, and a coagulation aid reaction tank 123 connected in sequence. The neutralization reaction tank 121 is used to adjust the pH of the wastewater and can be made of carbon steel with an anti-corrosion lining to prevent acid and alkali corrosion. The mixing reaction tank 122 ensures thorough mixing of the wastewater and reagents and can be designed with a cylindrical structure to improve mixing efficiency. The coagulation aid reaction tank 123 promotes the formation of flocs and can be equipped with special guide plates inside to guide the water flow and accelerate the reaction speed. Each reaction tank 12 is equipped with a mechanical agitator 124 controlled by an electrical control system. The mechanical agitator 124 can be a paddle agitator for good mixing effect or a turbine agitator for stronger mixing force.

[0050] The dosing system 15 includes several storage tanks 151 and a dosing pump 152 connected to the storage tanks via pipelines. The dosing pump 152 draws and adds the corresponding chemical agent into the reaction tank 12. The dosing pipeline can be made of corrosion-resistant plastic pipe.

[0051] Reference Figure 1 , Figure 2In this embodiment, the bottom of the sedimentation tank 13 is funnel-shaped, but it can also be rectangular. A filtration mechanism 2 is installed inside the sedimentation tank 13. The filtration mechanism 2 includes a filtration assembly 21 and a drive assembly 22. The filtration assembly 21 includes a fixed filter plate 211 fixedly connected to the inner wall of the inclined sedimentation tank 13, a pushing filter plate 212 slidably connected to the fixed filter plate 211, a baffle plate 3 disposed on the pushing filter plate 212, and a control component 4 for controlling the rotation of the baffle plate 3 to intercept water. In this embodiment, both the pushing filter plate 212 and the fixed filter plate 211 can be made of stainless steel mesh, which has high strength and corrosion resistance. Ceramic filter plates can also be used, resulting in better filtration. The fixed filter plate 211 has a drop outlet 2121 for flocculants to fall into. The sedimentation tank 13 is equipped with a collection component 125 for collecting the flocculants falling from the drop outlet 2121. The collection component 125 specifically includes a collection tank and a discharge pipe connected to the collection tank. The collection component 125 is made of plastic, which is lightweight and corrosion resistant. Alternatively, it can be a metal collection box with higher strength.

[0052] The sliding connection between the push filter plate 212 and the fixed filter plate 211 can be achieved through the cooperation of guide rails and sliders to ensure the smooth movement of the push filter plate 212. Several push filter plates 212 are provided, arranged in a stepped manner, with adjacent push filter plates 212 sliding relative to each other.

[0053] The drive assembly 22 is used to drive the push filter plate 212 to move horizontally, thereby driving the push filter plate 212 to push the flocculants on the fixed filter plate 211. The drive assembly 22 includes a moving part 222 that reciprocates with the drive plate 221 in the horizontal direction. The drive plate 221 is fixed to the end of the push filter plate 212 away from the fixed filter plate 211. The moving part 222 can be an electric push rod, which has high control precision, or a cylinder, which can provide a large thrust, or a transmission between a drive motor and a lead screw.

[0054] In another embodiment, the upper surface of the push filter plate 212 may be inclined downward toward the fixed filter plate 211 to reduce the possibility of accumulation.

[0055] The outlet end of the pipe connected to the coagulation reaction tank 123 is positioned towards the push filter plate 212, and the baffle plate 3 is positioned at the end of the push plate close to the fixed filter plate 211.

[0056] Reference Figure 2 , Figure 3The baffle plate 3 is rotatably connected to the push filter plate 212. The push filter plate 212 has a rotating groove 2122 for the baffle plate 3 to be rotatably mounted. The baffle plate 3 specifically includes a blocking section 31 and a connecting section 32 connected to the blocking section 31. A first rotating rod 33 is fixedly inserted at the connection between the connecting section 32 and the blocking section 31. The first rotating rod 33 is rotatably connected to the push filter plate 212. The control component 4 includes a first torsion spring coaxially sleeved on the first rotating rod 33. As the drive assembly 22 drives the push filter plate 212 to move away from the fixed filter plate 211, the first torsion spring forces the free end of the blocking section 31 to move away from the fixed filter plate 211. The free end of the connecting section 32 abuts against the fixed filter plate 211. The fixed filter plate 211 is provided with a guide surface. As the drive assembly 22 drives the push filter plate 212 to move closer to the fixed filter plate 211, the free end of the connecting section 32 drives the free end of the baffle plate 3 to move closer to the fixed filter plate 211 along with the guide surface, thereby... Figure 4 As shown.

[0057] Furthermore, the free end of the blocking section 31 is provided with an abutting section 34, which abuts against the upper surface of the fixed filter plate. The abutting section 34 and the blocking section 31 can be arranged in an L-shape or an arc shape to clean the fixed filter plate 211. It should be noted that a yarn can be provided at the end of the abutting part of the pushing filter plate 212 to further improve the cleaning of the fixed filter plate 211.

[0058] In another embodiment, such as Figure 5 As shown, since the control component 4 includes a first torsion spring, when there is a lot of flocculent material and it is heavy, it will squeeze the baffle plate 3 to rotate. If it is desired to further increase the sedimentation time of the flocculent material, the control component 4 may also include a limiting block 41 set on the inner wall of the sedimentation tank 13 to restrict the free end of the connecting section 32 from moving towards the direction of pushing the filter plate 212, so that the baffle plate 3 can be kept tilted.

[0059] Wastewater treatment system 14 further treats the wastewater after sedimentation. Wastewater treatment system 14 may use activated carbon filtration devices to effectively adsorb harmful substances in the water, or it may use ion exchange resin devices to remove heavy metal ions from the water.

[0060] The dosing system 15 is used to add chemicals to the reaction tank 12. The dosing system 15 may include a chemical storage tank, a metering pump, and delivery pipes 2212. The chemical storage tank may be made of plastic to prevent chemical corrosion. The metering pump can precisely control the amount of chemical added, and the delivery pipes 2212 may be made of corrosion-resistant rubber tubing.

[0061] The electrical control system controls the operation of the entire system. The electrical control system may include a control cabinet, sensors, and controllers. The control cabinet houses various electrical components; sensors detect parameters such as water level and water quality in each tank; and controllers control the operation of each piece of equipment based on the information fed back from the sensors.

[0062] The implementation principle of the mobile integrated chemical precipitation treatment device in this application embodiment is as follows: The mobile integrated chemical precipitation treatment device, through the design of the integrated frame 1, facilitates overall movement and adapts to the seasonal production and relocation needs of enterprises. Wastewater enters from the inlet tank 11, and sequentially passes through the neutralization reaction tank 121, the mixing reaction tank 122, and the coagulation aid reaction tank 123. Under the action of the dosing system 15 adding reagents and the mechanical stirrer 124 stirring, a chemical reaction occurs to form flocs. The flocs enter the sedimentation tank 13, and are pushed to the drop outlet 2121 by the filter plate 212 of the filtration mechanism 2, falling into the collection container 125. After sedimentation and filtration, the wastewater enters the sewage treatment system 14 for further treatment, ultimately achieving effective wastewater treatment. Compared with traditional wastewater treatment methods, this reduces initial investment, improves flexibility, and reduces resource idleness and waste.

[0063] Example 2:

[0064] Reference Figure 6 The difference from Embodiment 1 is that the number of baffle plates 3 corresponds to the number of push filter plates 212. When subjected to pressure from the flocculants, the free end of the baffle rotates downward, thereby allowing some flocculants to flow and reducing excessive flocculants flowing into the collection tank, thus achieving a certain amount of control.

[0065] Example 3:

[0066] Reference Figure 7 The difference from Embodiment 1 is that the filter assembly 21 is arranged at intervals along the height direction of the sedimentation tank 13, and the filter holes on the push filter plate 212 and the fixed filter plate 211 are arranged to gradually decrease towards the bottom wall of the sedimentation tank 13. The number of collection pieces 125 corresponds to the number of filter assemblies 21.

[0067] Several filter components 21 can be as follows Figure 7 As shown, one side can be set up, or as... Figure 8 As shown, the drive plate 221 is staggered on both sides. For the latter, the drive plate 221 has several water outlet troughs 2211 spaced apart along its height direction, corresponding to the filter assembly 21. Below the filter assembly 21, there is a telescopic guide plate 23. The upper end of the guide plate 23 is located on the side of the drop outlet 2121 away from the sedimentation tank 13, and the lower end of the guide plate 23 is connected to the water outlet trough 2211.

[0068] Example 4:

[0069] Reference Figure 9 The difference from Embodiment 1 is that the sedimentation tank 13 is further equipped with a cleaning component 5 for cleaning the push filter plate 212 closest to the drive plate 221. The cleaning component 5 includes a nozzle 51 disposed on the drive plate 221 and a water conveying component 52 connected to the nozzle 51. In this embodiment, the nozzle 51 can be a high-pressure nozzle 51, which can generate strong water spray pressure to effectively clean the push filter plate 212. In this embodiment, several nozzles 51 are arranged at intervals along the width and height directions of the drive plate 221, and several nozzles 51 located at the same level are connected by a connecting pipe 511.

[0070] Reference Figure 9 , Figure 10 The drive plate 221 has a conveying pipe 2212 fixedly inserted along its height direction. A connecting pipe 511 connected to the nozzle 51 is fixedly inserted through the drive plate 221 to communicate with the water supply pipe 526. The water supply component 52 includes a collection tank 521, a piston 522 built into the collection tank 521, a piston rod 523 connected to the piston 522, two one-way valves 524 and 525 respectively fixedly inserted into the collection tank 521, and a water supply pipe 526 communicating with the second one-way valve 525. The flow direction of the first one-way valve 524 is from outside the tank to inside the tank, and the second one-way valve 525 allows water to flow from inside the tank to the water supply pipe 526. When the drive plate 221 moves horizontally... Taking the filter assembly 21 located on the right side of the drive plate 221 as an example, when the drive plate 221 moves to the left, it pulls the piston rod 523, causing the water in the collection tank 521 to flow through the first one-way valve 524. Then, when the drive plate 221 moves to the right, it squeezes the water in the collection tank 521, causing the water to flow through the second one-way valve 525, the water supply pipe 526, the delivery pipe 2212, and the connecting pipe 511 to the nozzle 51 for spraying. For drive plates 221 with filter assemblies 21 on both sides, with two collection tanks 521 respectively located on both sides of the drive plate 221, the piston rod 523 can be a telescopic rod for space considerations.

[0071] It should be noted that if the bottom inclination angle of the sedimentation tank 13 is too large, a combination of a water pump and a water pipe can be used. The water pump can be built into the sedimentation tank 13, while the water pipe is fixedly installed through the drive plate 221, so that the water drawn into the delivery pipe 2212 is sprayed out with the nozzle 51, ensuring the stability of the water supply. When the inclination angle is small, the former can be used to facilitate the movement of the piston rod 523. To accommodate the movement of the drive plate 221, the piston rod 523 can be a telescopic rod.

[0072] Reference Figure 9 , Figure 11The drive plate 221 is equipped with a control component 6 for adjusting the angle between the nozzle 51 and the drive plate 221, thereby controlling the spray angle of the nozzle 51. A second rotating rod 7 is rotatably connected to the drive plate 221, and a connecting plate 71 is fixedly connected to the second rotating rod 7. Two connecting plates 71 are provided and are respectively provided at both ends of the second rotating rod 7. A connecting pipe 511 is located between the two connecting plates 71 and connected to them. The control component 6 includes a second torsion spring 61 coaxially sleeved and fixed to the second rotating rod 7, a gear 62 fixedly sleeved to the second rotating rod 7, and a rack 63 meshing with the gear 62. In this embodiment, the elastic coefficient of the second torsion spring 61 can be selected according to the adjustment requirements of the nozzle 51. The second torsion spring 61 forces the spray direction of the nozzle 51 to be set downward. The rack 63 is fixedly connected to the inner wall of the sedimentation tank 13. The rack 63 is set above the gear 62, and the teeth on the rack 63 are set downward. The cooperation between the gear 62 and the rack 63 can accurately control the rotation angle of the nozzle 51.
