Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and more specifically, it relates to a wastewater treatment device after chemical purification and its application process. Background Technology

[0002] Wastewater treatment after chemical purification is a crucial part of industrial production and scientific research activities. Its purpose is to purify and treat the wastewater generated after chemical purification processes in order to reduce environmental pollution and make the wastewater meet the standards for discharge or reuse.

[0003] However, most existing wastewater treatment devices after chemical purification use the method of adding chemical reagents for precipitation, but they still have the following shortcomings when in use:

[0004] 1. Traditional chemical reagent addition methods usually involve a one-time addition, which can easily lead to excessively high or low concentrations of chemical reagents in certain areas, affecting reaction results and efficiency, increasing processing costs, and making it difficult to achieve precise addition in stages to meet the needs of different reaction stages.

[0005] 2. Common stirring blades cannot adaptively adjust according to the wastewater volume, which can easily lead to uneven mixing, dead corners, and material accumulation, affecting the full mixing of wastewater and chemical reagents, reducing reaction efficiency and treatment quality;

[0006] 3. During the wastewater discharge process, the outlet is easily blocked by sediment or impurities, causing production interruption and equipment failure. Existing dredging methods are often ineffective or complicated to operate.

[0007] This paper studies and improves the existing structure and its shortcomings, and provides a wastewater treatment device after chemical purification and its application process. Summary of the Invention

[0008] To address the aforementioned technical problems, this invention provides a wastewater treatment device and its application process after chemical purification, thereby resolving the problems described above.

[0009] A wastewater treatment device after chemical purification includes a treatment cylinder and a support frame. The support frame is located below the treatment cylinder. The lower end of the treatment cylinder has an outlet with a rubber stopper inside. The upper end of the treatment cylinder has an installation groove with a positioning column fixedly installed in the inner wall of the installation groove. A filter screen is inserted into the positioning column. A cylinder cover is installed at the upper end of the treatment cylinder with symmetrically formed first sliding grooves. A fixing frame is fixedly installed at the upper end of the cylinder cover. A third sliding groove is formed on the side wall of the fixing frame. A water storage device is fixedly installed inside the fixing frame. Connecting pipes are symmetrically installed below the water storage device, and both connecting pipes are internally located within the cylinder cover. A drive mechanism is fixedly installed inside the water storage device.

[0010] The driving mechanism includes a first driving motor, which is fixedly installed inside the water storage tank. A stirring rod is installed on the output shaft of the first driving motor. A limit groove is formed in the middle of the stirring rod, and a second sliding groove is provided on the upper part of the stirring rod.

[0011] Preferably, an inner rod is slidably installed inside the stirring rod, and an impact head is fixedly installed at the lower end of the inner rod. The impact head and the water outlet are located on the same vertical line.

[0012] Preferably, a limiting strip is fixedly installed on the side wall of the inner rod, the limiting strip is slidably installed in the second groove, and a rotating rod is slidably installed on the stirring rod.

[0013] Preferably, an inner block is fixedly installed in the inner wall of the rotating rod, the inner block is slidably installed in the limiting groove, a blocking strip is slidably installed inside each of the two first sliding grooves, and the two blocking strips are respectively slidably installed in the two third sliding grooves.

[0014] Preferably, a spring is fixedly installed on each of the two blocking strips, and the ends of the two springs away from the two blocking strips are fixedly connected to the cylinder cover.

[0015] Preferably, a second drive motor is fixedly installed on the upper end of the cylinder cover, a first gear is installed on the output shaft of the second drive motor, and a second gear is rotatably installed on the stirring rod, with the second gear meshing with the first gear.

[0016] Preferably, the second gear has a fourth sliding groove and an operating port, the operating port and the fourth sliding groove are connected, a screw is fixedly installed inside the fourth sliding groove, and threaded rings are symmetrically threaded on the screw.

[0017] Preferably, a wedge-shaped strip is slidably installed inside the fourth groove, and a side block is fixedly installed on the side wall of the wedge-shaped strip. The side block is slidably installed on the screw and located between two threaded rings.

[0018] Preferably, at least three first stirring blades are fixedly installed on the side wall of the stirring rod, and at least three second stirring blades are slidably installed on each of the at least three first stirring blades. At least three float plates are fixedly installed on each of the at least three second stirring blades, and ball bearings are rotatably installed on the opposite ends of each of the at least three second stirring blades.

[0019] A process for using a wastewater treatment device after chemical purification includes the following steps:

[0020] S1: Check that all parts of the equipment are in good working order, and ensure that the chemical reagents are prepared in sufficient quantities and placed inside the water tank;

[0021] S2: Pour the chemically purified wastewater into the treatment cylinder through the inlet on the cylinder cover. The wastewater first falls onto the filter screen for filtration, and then flows into the inside of the treatment cylinder.

[0022] S3: Wastewater is injected into the treatment cylinder. The three float plates are driven by buoyancy to slide the three second stirring blades inside the three first stirring blades, always keeping the stirring blades floating on the liquid surface and in a funnel shape.

[0023] S4: Rotate the threaded ring on the screw to adjust the height of the side block and wedge strip downwards until the wedge strip and the plug strip are on the same horizontal line;

[0024] S5: Start the first drive motor and the second drive motor. The first drive motor drives the stirring rod to rotate. When the stirring rod rotates, it drives the rotating rod to rotate and scrape the impurities trapped on the filter screen. At the same time, the first stirring blade and the second stirring blade stir the wastewater. Meanwhile, the second drive motor drives the first gear, the second gear and the wedge strip to rotate. When the wedge strip contacts the blocking strip, the chemical reagent flows from the water storage tank into the treatment cylinder through the connecting pipe and reacts with the wastewater.

[0025] S6: When feeding, rotate the threaded ring on the screw to adjust the wedge strip upward so that the wedge strip and the limit strip are at the same level. Then pull out the rubber stopper. The wedge strip rotates and contacts the limit strip, causing the inner rod and the impact head to move upward. When the wedge strip and the limit strip are misaligned, the impact head impacts the outlet under the action of gravity to clear the blockage.

[0026] S7: After wastewater treatment is complete, shut down the equipment, remove the filter screen to clean any residual substances, and perform maintenance on the equipment.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In this invention, a processing cylinder, a cylinder cover, a first chute, a water reservoir, a connecting pipe, a stirring rod, a plug, a spring, a second drive motor, a first gear, a second gear, and a wedge strip are provided. Under the action of the second drive motor, the first gear will rotate, which in turn will drive the second gear to rotate on the stirring rod. The second gear will then drive the wedge strip to rotate around its midpoint as the central axis. When the wedge strip contacts the plug, the plug will be squeezed and move downward inside the first chute, separating from the cylinder cover. At this time, the chemical reagent inside the water reservoir will flow into the processing cylinder through the connecting pipe. The plug will then stretch the spring. When the wedge strip and the plug are misaligned, the spring will reset the plug and seal the two connecting pipes. This allows the device to intermittently add chemical reagents. Adding reagents in stages can fully promote the reaction at different stages, avoiding excessively high or low local concentrations caused by adding reagents all at once, thereby improving the overall reaction efficiency.

[0029] In this invention, when chemical reagents react with certain ions in wastewater (e.g., heavy metal ions, alkaline earth metal ions, phosphate ions, fluoride ions, and arsenic ions) to form precipitates and remove them, stirring can accelerate the fusion speed of wastewater and chemical reagents, promote the full progress of the precipitation reaction, improve the utilization rate of chemical reagents, and reduce wastewater treatment costs.

[0030] In this invention, a treatment cylinder, a first stirring blade, a second stirring blade, and floats are provided. When waste liquid is injected into the treatment cylinder, the three floats are affected by the buoyancy of the waste liquid, which causes the three second stirring blades to slide within the three first stirring blades. This allows the three floats to always float on the water surface, enabling the stirring blades of the device to adaptively adjust according to the volume of waste water. Furthermore, at least the three second stirring blades can always be combined with the three first stirring blades to form a funnel shape, which helps guide the material to flow along a specific path, avoiding dead corners or accumulation of material in the mixing container. The funnel shape will generate different fluid flow patterns during rotation, promoting the mixing and circulation of waste water and chemical reagents, making the mixing more thorough and uniform, and improving reaction efficiency and treatment quality.

[0031] In this invention, a water outlet, a rubber stopper, an inner rod, an impact head, a limiting strip, a second drive motor, a second gear, a screw, and a wedge strip are provided. During material feeding, the wedge strip can be adjusted upward by rotating the threaded ring on the screw. When the wedge strip and the limiting strip are on the same horizontal line, the rubber stopper can be pulled out of the water outlet. At this time, when the second drive motor drives the second gear and the wedge strip to rotate, the wedge strip will contact the limiting strip. The limiting strip will be forced to move the inner rod and the impact head upward. When the wedge strip and the limiting strip are misaligned and separated, the impact head will impact the water outlet under the action of gravity, thereby clearing the water outlet and reducing production interruptions and equipment failures caused by blockages, thus improving the continuity and reliability of the entire production process.

[0032] In this invention, a filter screen, a stirring rod, a rotating rod, and a spring are provided. When the stirring rod rotates, it drives the rotating rod, which is limited by the stirring rod, to rotate as well. The rotating rod is in contact with the filter screen, so the impurities trapped on the filter screen are scraped by the rotation of the spring. This can effectively prevent the filtered impurities from clogging the filter screen. This device can keep the filtration channel unobstructed and improve filtration efficiency and continuity.

[0043] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0044] Please see Figure 1 - Figure 9This invention provides a wastewater treatment device after chemical purification, including a treatment cylinder 11 and a support frame 12. The support frame 12 is located below the treatment cylinder 11. The lower end of the treatment cylinder 11 has an outlet 13, and a rubber stopper 14 is installed inside the outlet 13. The upper end of the treatment cylinder 11 has an installation groove 15, and a positioning column 16 is fixedly installed in the inner wall of the installation groove 15. A filter screen 17 is inserted into the positioning column 16. The filter screen 17 is installed by insertion, making the installation process more convenient. The upper end of the treatment cylinder 11 has a cylinder cover 21, and an inlet is provided on the cylinder cover 21. A first sliding groove 22 is symmetrically provided on the cylinder cover 21. A fixing frame 23 is fixedly installed on the upper end of the cylinder cover 21. A third sliding groove 38 is provided on the side wall of the fixing frame 23. A water storage tank 24 is fixedly installed inside the fixing frame 23. Connecting pipes 25 are symmetrically installed below the water storage tank 24. Both connecting pipes 25 are internally located in the cylinder cover 21. A driving mechanism is fixedly installed inside the water storage tank 24.

[0045] The drive mechanism includes a first drive motor 26, which is fixedly installed inside the water storage tank 24. A stirring rod 27 is mounted on the output shaft of the first drive motor 26. A limit groove 28 is formed in the middle of the stirring rod 27, and a second sliding groove 29 is provided on the upper part of the stirring rod 27. An inner rod 31 is slidably installed inside the stirring rod 27. An impact head 32 is fixedly installed at the lower end of the inner rod 31. The impact head 32 is located on the same vertical line as the water outlet 13. A limit strip 33 is fixedly installed on the side wall of the inner rod 31 and is slidably installed in the second sliding groove 29. A rotating rod 34 is slidably installed on the stirring rod 27. An inner block 35 is fixedly installed in the inner wall of the rotating rod 34 and is slidably installed in the second sliding groove 29. A rotating rod 34 is slidably installed on the stirring rod 27. An inner block 35 is fixedly installed in the inner wall of the rotating rod 34 and is slidably installed in the second sliding groove 29. Installed in the limiting groove 28, the two first sliding grooves 22 are each slidably installed with a blocking strip 36. The two blocking strips 36 are respectively slidably installed in the two third sliding grooves 38. The two blocking strips 36 are each fixedly installed with a spring 37. The ends of the two springs 37 away from the two blocking strips 36 are fixedly connected to the cylinder cover 21. When the stirring rod 27 rotates, it will drive the rotating rod 34, which is limited by it, to rotate as well. The rotating rod 34 is in a state of contact with the filter screen 17. Therefore, under the rotation of the spring 37, the impurities trapped on the filter screen 17 will be scraped, which can effectively prevent the filtered impurities from clogging the filter screen 17. This device can keep the filtration channel unobstructed and improve filtration efficiency and continuity.

[0046] A second drive motor 41 is fixedly installed on the upper end of the cylinder cover 21. A first gear 42 is installed on the output shaft of the second drive motor 41. A second gear 43 is rotatably installed on the stirring rod 27. The second gear 43 meshes with the first gear 42. A fourth sliding groove 44 and an operating port 45 are provided on the second gear 43. The operating port 45 and the fourth sliding groove 44 are connected. A screw 46 is fixedly installed inside the fourth sliding groove 44. A threaded ring 47 is symmetrically threaded on the screw 46. A wedge-shaped strip 48 is slidably installed inside the fourth sliding groove 44. When discharging material, the wedge-shaped strip 48 can be adjusted upward by rotating the threaded ring 47 on the screw 46. When the wedge 48 and the limiting strip 33 are on the same horizontal line, the rubber stopper 14 can be pulled out from the outlet 13. When the second drive motor 41 drives the second gear 43 and the wedge 48 to rotate, the wedge 48 will contact the limiting strip 33. The limiting strip 33 will be forced to move the inner rod 31 and the impact head 32 upward. When the wedge 48 and the limiting strip 33 are misaligned and separated, the impact head 32 will impact the outlet 13 under the action of gravity, thereby clearing the outlet 13, reducing production interruptions and equipment failures caused by blockage, and improving the continuity and reliability of the entire production process.

[0047] A side block 49 is fixedly installed on the side wall of the wedge-shaped bar 48. The side block 49 is slidably installed on the screw 46 and located between two threaded rings 47. At least three first stirring blades 51 are fixedly installed on the side wall of the stirring rod 27. Second stirring blades 52 are slidably installed on each of the at least three first stirring blades 51. Float plates 53 are fixedly installed on each of the at least three second stirring blades 52. Ball bearings 54 are rotatably installed on the opposite ends of each of the at least three second stirring blades 52. In use, the chemically purified wastewater can be poured into the treatment cylinder 11 through the inlet on the cylinder cover 21. At this time, the wastewater will first fall into the filter screen 17 for filtration, and then flow to the treatment cylinder. Inside the cylinder 11, the threaded ring 47 on the screw 46 can be rotated to adjust the height of the side block 49 and the wedge strip 48 downwards. When the wedge strip 48 is adjusted to be on the same horizontal line as the blocking strip 36, the first drive motor 26 can be started. Under the action of the first drive motor 26, the stirring rod 27 will rotate, which will then drive the first stirring blade 51 to rotate. The first stirring blade 51 will then drive the second stirring blade 52 to rotate. Under the combined action of the first stirring blade 51 and the second stirring blade 52, the wastewater inside the treatment cylinder 11 will be stirred. At the same time, the second drive motor 41 can be started. Under the action of the second drive motor 41, the first gear 42 will rotate accordingly. At this time, the first gear 42 will drive the second gear 43 to rotate on the stirring rod 27. The second gear 43 will drive the wedge strip 48 to rotate around its midpoint as the central axis. When the wedge strip 48 contacts the blocking strip 36, the blocking strip 36 will be squeezed and move downward inside the first slide groove 22. At this time, the blocking strip 36 will separate from the cylinder cover 21. At this time, the chemical reagent inside the water reservoir 24 will flow into the processing cylinder 11 through the connecting pipe 25. At this time, the blocking strip 36 will drive the spring 37 to stretch accordingly. When the wedge strip 48 and the blocking strip 36 are misaligned, at this time... Spring 37 will drive the plug 36 to reset and seal the two connecting pipes 25, allowing the device to add chemical reagents intermittently. Adding reagents in stages can fully promote the reaction at different stages, avoiding excessively high or low local concentrations caused by adding all at once, thereby improving the overall reaction efficiency. It can form precipitates with certain ions in wastewater (such as heavy metal ions, alkaline earth metal ions, phosphate ions, fluoride ions, and arsenic ions) for removal. Combined with stirring, it can accelerate the fusion speed of wastewater and chemical reagents, promote the full progress of precipitation reaction, improve the utilization rate of chemical reagents, and reduce wastewater treatment costs.When waste liquid is injected into the treatment cylinder 11, the three floats 53, influenced by the buoyancy of the waste liquid, will cause the three second stirring blades 52 to slide within the three first stirring blades 51, ensuring that the three floats 53 remain floating on the water surface. This allows the stirring blades of the device to adaptively adjust according to the wastewater volume. Furthermore, at least the three second stirring blades 52 can always combine with the three first stirring blades 51 in a funnel shape, which helps guide the material along a specific path, preventing dead zones or accumulation of material in the mixing container. The funnel shape generates different fluid flow patterns during rotation, promoting the mixing and circulation of wastewater and chemical reagents, resulting in more thorough and uniform mixing, and improving reaction efficiency and treatment quality.

[0048] A process for using a wastewater treatment device after chemical purification includes the following steps:

[0049] S1: Check that all parts of the equipment are in good working order, and ensure that the chemical reagents are prepared in sufficient quantities and placed inside the water tank 24;

[0050] S2: The chemically purified wastewater is poured into the treatment cylinder 11 through the inlet on the cylinder cover 21. The wastewater first falls onto the filter screen 17 for filtration, and then flows into the interior of the treatment cylinder 11.

[0051] S3: Wastewater is injected into the treatment cylinder 11. The three float plates 53 are driven by buoyancy to slide the three second stirring blades 52 inside the three first stirring blades 51, keeping the stirring blades floating on the liquid surface and in a funnel shape.

[0052] S4: Rotate the threaded ring 47 on the screw 46 to adjust the height of the side block 49 and the wedge strip 48 downwards until the wedge strip 48 and the plug strip 36 are on the same horizontal line;

[0053] S5: Start the first drive motor 26 and the second drive motor 41. The first drive motor 26 drives the stirring rod 27 to rotate. When the stirring rod 27 rotates, it drives the rotating rod 34 to rotate and scrape the impurities trapped on the filter screen 17. At the same time, the first stirring blade 51 and the second stirring blade 52 stir the wastewater. Meanwhile, the second drive motor 41 drives the first gear 42, the second gear 43 and the wedge strip 48 to rotate. When the wedge strip 48 contacts the blocking strip 36, the chemical reagent flows from the water storage tank 24 into the treatment cylinder 11 through the connecting pipe 25 and reacts with the wastewater.

[0054] S6: When feeding, rotate the threaded ring 47 on the screw 46 to adjust the wedge 48 upward so that the wedge 48 and the limiting strip 33 are at the same level. Then pull out the rubber stopper 14. The wedge 48 rotates and contacts the limiting strip 33, which drives the inner rod 31 and the impact head 32 to move upward. When the wedge 48 and the limiting strip 33 are misaligned, the impact head 32 impacts the outlet 13 under the action of gravity to clear the blockage.

[0055] S7: After wastewater treatment is completed, turn off the equipment, remove filter screen 17 to clean residual substances, and perform maintenance on the equipment.

[0056] Working principle:

[0057] The first step is to pour the chemically purified wastewater into the treatment cylinder 11 through the inlet on the cylinder cover 21. The wastewater will first fall into the filter screen 17 for filtration, and then flow into the treatment cylinder 11. Next, the threaded ring 47 on the screw 46 can be rotated to adjust the height of the side block 49 and the wedge strip 48 downwards. When the wedge strip 48 is adjusted to be on the same horizontal line as the blocking strip 36, the first drive motor 26 can be started. Under the action of the first drive motor 26, the stirring rod 27 will rotate, which in turn will drive the first stirring blade 51 to rotate. The first stirring blade 51 will then drive the second stirring blade 52 to rotate. The combined action of the first stirring blade 51 and the second stirring blade 52 will stir the wastewater inside the treatment cylinder 11. Simultaneously, the second drive motor 41 can be started, which will drive the first gear 42 to rotate. The first gear 42 will then drive the second gear 43 to rotate on the stirring rod 27, and the second gear 43 will drive the wedge strip 48 to rotate. Rotating around the central axis, when the wedge-shaped strip 48 contacts the blocking strip 36, the blocking strip 36 is squeezed and moves downward inside the first chute 22. At this time, the blocking strip 36 separates from the cylinder cover 21, and the chemical reagent inside the water tank 24 flows into the treatment cylinder 11 through the connecting pipe 25. At this time, the blocking strip 36 will drive the spring 37 to stretch. When the wedge-shaped strip 48 and the blocking strip 36 are misaligned, the spring 37 will drive the blocking strip 36 to reset and seal the two connecting pipes 25. This allows the equipment to intermittently add chemical reagents. Adding reagents in stages can fully promote the reaction at different stages, avoiding excessively high or low local concentrations caused by adding all at once, thereby improving the overall reaction efficiency. It can also form precipitates with certain ions in the wastewater (such as heavy metal ions, alkaline earth metal ions, phosphate ions, fluoride ions, and arsenic ions) for removal. Combined with stirring, it can accelerate the fusion speed of wastewater and chemical reagents, promote the full precipitation reaction, improve the utilization rate of chemical reagents, and reduce wastewater treatment costs.

[0058] In the second step, when waste liquid is injected into the treatment cylinder 11, the three float plates 53 will be affected by the buoyancy of the waste liquid, which will cause the three second stirring blades 52 to slide inside the three first stirring blades 51, so that the three float plates 53 can always float on the water surface. This allows the stirring blades of the device to be adaptively adjusted according to the volume of waste water, and at least the three second stirring blades 52 can always be combined with the three first stirring blades 51 to form a funnel shape, which helps to guide the material to flow along a specific path and avoid dead corners or accumulation of material in the mixing container. The funnel shape will generate different fluid flow patterns when rotating, promoting the mixing and circulation of waste water and chemical reagents, making the mixing more thorough and uniform, and improving the reaction efficiency and treatment quality.

[0059] Thirdly, during material feeding, the wedge strip 48 can be adjusted upward by rotating the threaded ring 47 on the screw 46. When the wedge strip 48 and the limiting strip 33 are on the same horizontal line, the rubber stopper 14 can be pulled out from the outlet 13. When the second drive motor 41 drives the second gear 43 and the wedge strip 48 to rotate, the wedge strip 48 will contact the limiting strip 33. The limiting strip 33 will be forced to move the inner rod 31 and the impact head 32 upward. When the wedge strip 48 and the limiting strip 33 are misaligned and separated, the impact head 32 will impact the outlet 13 under the action of gravity, thereby clearing the outlet 13, reducing production interruptions and equipment failures caused by blockage, and improving the continuity and reliability of the entire production process.

[0060] Fourthly, when the stirring rod 27 rotates, it will drive the rotating rod 34, which is limited by it, to rotate as well. The rotating rod 34 is in contact with the filter screen 17. Therefore, under the rotation of the spring 37, the impurities trapped on the filter screen 17 will be scraped, which can effectively prevent the filtered impurities from clogging the filter screen 17. This device can keep the filtration channel unobstructed and improve filtration efficiency and continuity.

Many modifications and variations will be apparent to those skilled in the art.

2. A process for using a chemically purified wastewater treatment device, implemented based on the chemically purified wastewater treatment device according to claim 1, wherein the method of using the chemically purified wastewater treatment device includes the following steps: S1: Check whether each component of the equipment is in good working order, and ensure that the chemical reagents are prepared in sufficient quantities and placed inside the water tank (24); S2: The chemically purified wastewater is poured into the treatment cylinder (11) through the inlet on the cylinder cover (21). The wastewater first falls onto the filter screen (17) for filtration, and then flows into the interior of the treatment cylinder (11). S3: Wastewater is injected into the treatment cylinder (11). The three float plates (53) are driven by buoyancy to slide the three second stirring blades (52) inside the three first stirring blades (51), keeping the stirring blades floating on the liquid surface and in a funnel shape. S4: Rotate the threaded ring (47) on the screw (46) to adjust the height of the side block (49) and the wedge strip (48) downwards until the wedge strip (48) and the plug strip (36) are on the same horizontal line; S5: Start the first drive motor (26) and the second drive motor (41). The first drive motor (26) drives the stirring rod (27) to rotate. When the stirring rod (27) rotates, it drives the rotating rod (34) to rotate and scrape the impurities trapped on the filter screen (17). At the same time, the first stirring blade (51) and the second stirring blade (52) stir the wastewater. At the same time, the second drive motor (41) drives the first gear (42), the second gear (43) and the wedge strip (48) to rotate. When the wedge strip (48) contacts the blocking strip (36), the chemical reagent flows from the water storage tank (24) into the treatment cylinder (11) through the connecting pipe (25) and reacts with the wastewater. S6: When feeding, rotate the threaded ring (47) on the screw (46) to adjust the wedge (48) upward so that the wedge (48) and the limiting strip (33) are at the same level. Then pull out the rubber stopper (14). The wedge (48) rotates and contacts the limiting strip (33), which drives the inner rod (31) and the impact head (32) to move upward. When the wedge (48) and the limiting strip (33) are misaligned, the impact head (32) impacts the outlet (13) under the action of gravity to clear the blockage. S7: After the wastewater treatment is completed, shut down the equipment, remove the filter screen (17) to clean the residual substances, and perform maintenance on the equipment.
