Description

Technical Field

[0001] This application relates to the technical field of sedimentation equipment, and in particular to a high-efficiency coagulation sedimentation equipment. Background Technology

[0002] The working principle of coagulation sedimentation equipment is mainly to add coagulants to wastewater. After hydrolysis in the water, the coagulants form colloids. These colloids can adsorb and neutralize fluoride ions and other suspended solids and colloidal substances in the wastewater. Through the adsorption, bridging, and trapping effects of the coagulants, these substances are formed into larger particles or flocs, which then settle to the bottom under gravity, thereby purifying the wastewater.

[0003] To achieve the coagulation and sedimentation process, existing coagulation and sedimentation equipment typically includes a sedimentation tank, a mixing device, and a filtration device. In practice, wastewater and coagulant are fed into the sedimentation tank and thoroughly mixed by the mixing device, allowing the coagulant to react with the pollutants in the wastewater to form flocs. Subsequently, the wastewater is allowed to settle in the sedimentation tank for a period of time, allowing the flocs to settle to the bottom under gravity. Finally, the sediment is collected by the filtration device. While this traditional method effectively removes pollutants from wastewater, it has some shortcomings in practical applications.

[0004] However, existing coagulation and sedimentation equipment typically requires sequential steps of stirring, sedimentation, and filtration when treating wastewater. This results in a lengthy treatment process, severely impacting wastewater treatment efficiency. Especially in large-scale industrial production, excessively long treatment times lead to increased costs, reduced production efficiency, and an inability to meet the demand for rapid treatment of large volumes of wastewater. Therefore, shortening wastewater treatment time and improving treatment efficiency has become an urgent technical problem to be solved. Summary of the Invention

[0005] In order to shorten wastewater treatment time, this application provides a high-efficiency coagulation sedimentation device.

[0006] This application provides a high-efficiency coagulation and sedimentation device, which adopts the following technical solution:

[0007] A high-efficiency coagulation and sedimentation device, including

[0008] A coagulation cylinder, wherein a coagulation chamber is formed inside the coagulation cylinder, an inlet pipe and a dosing pipe are provided at the top of the coagulation cylinder, and a drain pipe is provided at the bottom of the coagulation cylinder;

[0009] A stirring roller is rotatably connected to the coagulation cylinder and located inside the coagulation chamber. The coagulation cylinder is provided with a driving component that drives the stirring roller to rotate.

[0010] Multiple stirring blades are evenly spaced along the circumferential direction on the outer periphery of the stirring roller, and a collection cavity is formed inside the stirring roller.

[0011] The outer periphery of the stirring roller has a plurality of inlets evenly spaced along the circumferential direction. Each inlet corresponds to one of the stirring blades and is located between adjacent stirring blades.

[0012] The stirring roller is hinged to a sealing plate for sealing the inlet, and the stirring roller and the sealing plate are each formed with a plurality of water-permeable holes at even intervals.

[0013] A control component is disposed on the stirring roller. When the stirring blade moves from a horizontal position to a vertical position, the control component controls the sealing plate to flip into the collection chamber.

[0014] An elastic drive element is disposed on the stirring roller. When the stirring blade moves downward from a vertical position, the elastic drive element drives the sealing plate to flip and block the inlet.

[0015] The coagulation cylinder is provided with a discharge pipe extending into the collection chamber, and the stirring roller rotates relative to the discharge pipe;

[0016] A water pump is installed outside the concrete drum, and the pump's inlet is connected to the drain pipe.

[0017] By adopting the above technical solution and through the design of the stirring roller, the three steps of stirring, sedimentation, and filtration are carried out simultaneously, greatly shortening the wastewater treatment time. The stirring blades on the stirring roller continuously agitate the wastewater and coagulant during rotation, promoting a full reaction between the coagulant and pollutants in the wastewater to form flocs. The design of the sealing plate and permeable holes prevents the flocs from being collected into the collection chamber during stirring; instead, the wastewater flows back into the coagulation chamber through the permeable holes, further promoting floc formation. When the stirring blades move upward, the sealing plate opens, allowing the flocs to enter the collection chamber; when the stirring blades move downward, the sealing plate closes, restricting floc loss. Finally, the treated flocs are discharged through the drain pipe and a water pump, while the wastewater in the coagulation chamber is discharged through the drain pipe.

[0018] Optionally, a hinge shaft is rotatably connected inside the stirring roller, and the sealing plate is disposed on the outer periphery of the hinge shaft;

[0019] The elastic driving component is a driving coil spring, which is sleeved on the outer periphery of the hinge shaft. The driving coil spring drives the sealing plate to flip and seal the inlet.

[0020] By adopting the above technical solution, when the stirring blade moves from a horizontal to a vertical position, the control component controls the sealing plate to flip into the collection chamber, opening the inlet and allowing wastewater to flow into the collection chamber. When the stirring blade moves from a vertical to a downward position, the drive spring drives the sealing plate to flip and block the inlet, restricting the outflow of coagulated material. This allows the coagulant in the coagulation chamber to better coagulate with impurities such as fluoride ions in the wastewater, improving wastewater treatment efficiency.

[0021] Optionally, the control component includes a control column, a control gear, and a control rack;

[0022] The control column is slidably connected to the stirring blade and the stirring roller respectively, and the control rack is disposed on the outer wall of the control column and slides inside the stirring roller;

[0023] The control gear is disposed on the outer periphery of the hinge shaft, the control gear rotates inside the stirring roller, and the control rack meshes with the control gear;

[0024] The circumferential wall of the coagulation chamber is formed with a groove for the end of the control column to slide, and the stirring roller is formed with a guide surface to guide the control column to slide to the wall of the coagulation chamber.

[0025] When the control column slides in the groove, the sealing plate blocks the inlet;

[0026] When the control column slides against the wall of the coagulation chamber, the control column slides into the stirring roller, and at this time the hinge shaft drives the sealing plate to flip into the collection chamber.

[0027] By adopting the above technical solution, the control component can accurately control the opening and closing of the sealing plate, ensuring that the wastewater can smoothly carry the coagulant into the mixing roller during the mixing process and be discharged in time when the mixing stops. This reduces the time waste caused by separating the mixing and sedimentation steps in traditional equipment and significantly improves the wastewater treatment efficiency.

[0028] Optionally, the stirring blade is slidably connected to the peripheral wall of the coagulation chamber on the side away from the stirring roller.

[0029] By adopting the above technical solution, the side of the stirring blade away from the stirring roller is slidably connected to the peripheral wall of the coagulation chamber. This allows the stirring blade to better conform to the inner wall of the coagulation chamber during rotation, effectively reducing residues on the inner wall and improving coagulation efficiency. Simultaneously, it enables the stirring blade to move and agitate more wastewater.

[0030] Optionally, limiting plates are respectively provided on both opposite sides of the stirring blade, and the limiting plates and the stirring blade surround each other to form a water collection tank.

[0031] By adopting the above technical solution, limiting plates are set on both sides of the stirring blades, and the limiting plates and stirring blades surround to form a water collection tank, so that during the stirring process, the water collection tank can scoop up more wastewater and increase the amount of wastewater entering the collection chamber.

[0032] Optionally, the stirring roller is provided with a rotating shaft rotating on the coagulation cylinder at both opposite ends, the stirring roller is rotatably connected to an agitator located in the collection chamber, the agitator extends into the rotating shaft, and a plurality of agitator blades are evenly spaced along the circumferential side of the agitator.

[0033] The rotating shaft has a rotating groove surrounding it, and a connecting rack is provided on the groove wall around the rotating shaft.

[0034] The concrete drum is provided with a connecting shaft extending into the rotating groove, and a transmission gear is rotatably connected to the outer periphery of the connecting shaft, and the connecting rack meshes with the transmission gear;

[0035] A power gear is provided on the outer periphery of the agitator shaft. The power gear meshes with the transmission gear, and the transmission gear is located between the power gear and the connecting rack.

[0036] By adopting the above technical solution, a highly efficient combination of stirring and sedimentation steps in the wastewater treatment process is achieved. Specifically, the design of the rotating shaft and the agitator shaft enables the stirring roller to not only fully mix the wastewater and coagulant during rotation, but also to increase the amount of wastewater flowing from the collection chamber into the coagulation chamber.

[0037] Optionally, a drain groove is formed inside the agitator shaft, and the drain pipe extends into the drain groove, with the drain pipe rotating relative to the agitator shaft;

[0038] The agitator blade has an inlet hole on the side away from the agitator shaft that connects to the drain trough.

[0039] By adopting the above technical solution, a discharge groove is formed inside the agitator shaft, and the discharge pipe extends into the discharge groove and rotates relative to the agitator shaft, ensuring that the precipitate can be discharged smoothly.

[0040] Optionally, a sealing pipe is provided on the discharge pipe, and the outer peripheral wall of the sealing pipe is in sliding contact with the peripheral wall of the discharge trough;

[0041] An inlet is formed on the bottom wall of the sealing pipe.

[0042] By adopting the above technical solution, the inlet hole of the sealing pipe is partially blocked, thereby improving the effect of the drain pipe in extracting and collecting condensate in the collection chamber.

[0043] Optionally, the agitator shaft forms a receiving groove surrounding the discharge pipe, and the agitator shaft is provided with power teeth located on the peripheral sidewall of the receiving groove. The power teeth are evenly spaced circumferentially and correspond one-to-one with the agitator blade.

[0044] A pushing groove is formed circumferentially on the outer periphery of the drain pipe. The drain pipe is provided with a pushing block that slides in the pushing groove. The drain pipe is provided with a pushing spring installed in the pushing groove. The pushing spring pushes the pushing block to abut against one side wall of the pushing groove.

[0045] When the agitator shaft rotates, the power teeth push the push block to squeeze the push spring, and the push block can slide past the power teeth;

[0046] The outer periphery of the discharge pipe is provided with a limiting tooth adjacent to the pushing groove. When the stirring shaft rotates, the power tooth slides on the limiting tooth.

[0047] When the push spring is released elastically, the push block pushes the power tooth between the push block and the limiting tooth until it abuts the limiting tooth.

[0048] By adopting the above technical solution, when the stirring shaft stops rotating, the push spring pushes the push block to slide. At this time, the push block pushes the power tooth to slide to the limit tooth, which corrects the stirring blade and makes the corresponding stirring blade in a vertical state, so that the concrete can be extracted better.

[0049] Optionally, the push groove wall is provided with a friction layer, the friction layer is away from the limiting tooth, and the push block slides on the friction layer.

[0050] By adopting the above technical solution, the friction layer slows down the speed at which the push block slides toward the limiting tooth, so that the next adjacent power tooth can push the push block to slide in time.

[0051] In summary, this application includes at least one of the following beneficial effects:

[0052] 1. The stirring blades on the stirring roller continuously agitate the wastewater and coagulant during rotation, promoting a full reaction between the coagulant and pollutants in the wastewater to form flocs. The design of the sealing plate and permeable holes prevents the flocs from being collected in the collection chamber during agitation; instead, the wastewater flows back into the coagulation chamber through the permeable holes, further promoting floc formation. When the stirring blades move downwards, the sealing plate closes, limiting floc loss. Finally, the treated flocs are discharged through the drain pipe and a water pump, while the drain pipe drains the wastewater from the coagulation chamber.

[0053] 2. When the agitator shaft stops rotating, the push spring pushes the push block to slide. At this time, the push block pushes the power teeth to slide to the limit teeth to correct the agitator blades, so that the corresponding agitator blades are in a vertical state, which can better extract the concrete.

[0063] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0064] This application discloses a high-efficiency coagulation and sedimentation device.

[0065] See Figure 1 and Figure 2 The coagulation and sedimentation equipment includes a coagulation cylinder 1, an agitator roller 2, and a drive unit 15. The coagulation cylinder 1 is a cylindrical structure with its central axis extending horizontally. A coagulation chamber 11 is formed inside the coagulation cylinder 1, and the coagulation chamber 11 extends along the central axis of the coagulation cylinder 1.

[0066] The top of the coagulation cylinder 1 is fixedly connected to an inlet pipe 12 and a dosing pipe 13, which are respectively connected to the coagulation chamber 11 for inputting wastewater and coagulant. The bottom of the coagulation cylinder 1 is fixedly connected to a drain pipe 14, which is connected to the coagulation chamber 11 for discharging wastewater from the coagulation chamber 11.

[0067] See Figure 3 and Figure 4 The stirring roller 2 has a cylindrical structure and is located inside the coagulation chamber 11. The central axis of the stirring roller 2 coincides with the central axis of the coagulation cylinder 1. Rotating shafts 27 are fixedly connected to the opposite ends of the stirring roller 2. The rotating shafts 27 are rotatably connected to the coagulation cylinder 1, and the central axis of the rotating shafts 27 coincides with the central axis of the coagulation cylinder 1.

[0068] The coagulation cylinder 1 is equipped with a drive unit 15 for driving the stirring roller 2 to rotate. The drive unit 15 is a drive motor, which is fixed to the outer wall of the coagulation cylinder 1 by its own bracket. The output shaft of the drive motor is rotatably connected to the coagulation cylinder 1, and the output shaft of the drive motor is fixedly connected to one of the rotating shafts 27 and is coaxially arranged. When the drive motor starts, it drives the stirring roller 2 to rotate through the rotating shaft 27.

[0069] A stirring blade 21 is fixedly connected to the outer periphery of the stirring roller 2. Multiple sets of stirring blades 21 are evenly spaced along the circumference. In this embodiment, there are four sets of stirring blades 21, and multiple stirring blades 21 are evenly spaced along the axial direction of the stirring roller 2. When the stirring roller 2 rotates, the stirring blades 21 stir and mix the wastewater and coagulant in the coagulation chamber 11.

[0070] See Figure 5 and Figure 6A collection chamber 22 is formed inside the stirring roller 2, and an inlet 23 is formed on the outer periphery of the stirring roller 2, which is connected to the collection chamber 22. There are multiple inlets 23, which are evenly spaced along the circumference. Each inlet 23 corresponds to one stirring blade 21, and each inlet 23 is located between two adjacent stirring blades 21. The stirring roller 2 is rotatably connected to a hinge shaft 18, which passes through the inlets 23 and corresponds to one inlet 23. A sealing plate 24 is fixedly connected to the outer periphery of the hinge shaft 18. The sealing plate 24 has an arc-shaped plate structure. When the sealing plate 24 is flipped so that its central axis coincides with the central axis of the concrete cylinder 1, the sealing plate 24 seals the inlet 23.

[0071] The coagulation and sedimentation equipment also includes an elastic component, with an elastic drive element disposed on the stirring roller 2. The elastic drive element is a drive coil spring 26, which is sleeved on the outer periphery of the hinge shaft 18. One end of the drive coil spring 26 is engaged with the outer periphery of the hinge shaft 18, and the other end is engaged with the stirring roller 2. When the drive coil spring 26 is elastically released, the drive sealing plate 24 flips to block the inlet 23.

[0072] See Figure 6 and Figure 7 The coagulation and sedimentation equipment also includes a control component 3, which is located on the stirring roller 2. When the stirring blade 21 moves from a horizontal to a vertical position, the control component 3 controls the sealing plate 24 to flip into the collection chamber 22. The roller wall of the stirring roller 2 and the sealing plate 24 are each formed with permeable holes 25, which are multiple and evenly spaced, and are connected to the collection chamber 22. When the sealing plate 24 flips to open the inlet 23, wastewater in the collection chamber 22 enters. At this time, as the stirring roller 2 rotates, the wastewater flows out from the permeable holes 25 into the coagulation chamber 11 under the action of centrifugal force, while the flocculants in the wastewater are filtered and retained in the coagulation chamber 11.

[0073] The control assembly 3 includes a control column 31, a control gear 32, and a control rack 33. The control column 31 is slidably connected to the stirring blade 21 and the stirring roller 2, respectively, and corresponds one-to-one with the hinge shaft 18. The control rack 33 is fixedly connected to the outer wall of the control column 31 and slides within the stirring roller 2. The control gear 32 is fixedly connected to the outer periphery of the hinge shaft 18, rotates within the stirring roller 2, and meshes with the control rack 33. A groove 111 is formed circumferentially on the periphery of the coagulation chamber 11. When the sealing plate 24 blocks the inlet 23, the control column 31 is inserted into the groove 111. When the control column 31 slides in the groove 111, the sealing plate 24 remains in the state of blocking the inlet 23. The stirring roller 2 has a guide surface 112. When the end of the control column 31 slides on the guide surface 112, the control column 31 is guided to slide from the groove 111 to the wall of the coagulation chamber 11. When one of the stirring blades 21 flips upward to a horizontal position, the control column 31 slides on the guide surface 112 and slides from the chute 111 to the wall of the coagulation chamber 11. During the sliding of the control column 31 on the guide surface 112, the control column 31 slides into the stirring roller 2, causing the control rack 33 to drive the control gear 32 to rotate. The hinge shaft 18 drives the sealing plate 24 to flip into the collection chamber 22. At this time, the drive coil spring 26 enters the compressed state. During the sliding of the control column 31 on the wall of the coagulation chamber 11, the sealing plate 24 remains open at the inlet 23. Until the stirring blade 21 flips upward from the horizontal position to the vertical position, the control column 31 slides from the wall of the coagulation chamber 11 to align with the chute 111. At this time, the drive coil spring 26 is released elastically, pushing the sealing plate 24 to block the inlet 23. At the same time, when the sealing plate 24 flips, the hinge shaft 18 drives the control column 31 to insert into the chute 111 through the control gear 32.

[0074] See Figure 2 As the stirring blade 21 rotates from a horizontal to a vertical position, the wastewater carried by the stirring blade 21 flows through the inlet 23 and into the collection chamber 22. To increase the amount of wastewater entering the collection chamber 22, the end of the stirring blade 21 away from the stirring roller 2 is slidably connected to the periphery of the coagulation chamber 11, and limiting plates 211 are fixedly connected to the opposite side walls of the stirring blade 21. At this time, a water collection trough 212 is formed between the limiting plates 211 and the stirring blade 21. As the stirring blade 21 rotates from a horizontal to a vertical position, the water collection trough 212 scoops up the wastewater, increasing the amount of wastewater flowing into the inlet 23 along the stirring blade 21.

[0075] See Figure 4 The stirring roller 2 is provided with a stirring shaft 4, which is located in the collection chamber 22. The central axis of the stirring shaft 4 coincides with the central axis of the stirring roller. One end of the stirring shaft 4 is rotatably connected to the wall of the collection chamber 22, and the other end of the stirring shaft 4 extends into the rotating shaft 27.

[0076] The rotating shaft 27 has a rotating groove 271 surrounding the agitator shaft 4. A ring-shaped connecting rack 272 is fixedly connected to the side wall of the rotating groove 271. The concrete drum 1 is fixedly connected to a connecting shaft 273, which extends into the rotating groove 271. A transmission gear 274 is rotatably connected to the outer periphery of the connecting shaft 273. The transmission gear 274 is rotatably connected within the rotating groove 271, and the connecting rack 272 meshes with the transmission gear 274. A power gear 42 is fixedly connected to the outer periphery of the agitator shaft 4. The power gear 42 is rotatably connected within the rotating groove 271, and it meshes with the transmission gear 274. The transmission gear 274 is located between the power gear 42 and the connecting rack 272.

[0077] Agitator blades 41 are fixedly connected to the outer periphery of agitator shaft 4. There are multiple agitator blades 41, which are evenly spaced along the circumference. When agitator roller 2 rotates, connecting rack 272 drives power gear 42 to rotate through transmission gear 274, causing agitator shaft 4 to enter a rotating state. The rotation direction of agitator shaft 4 is opposite to the rotation direction of agitator roller 2. At this time, agitator blades 41 agitate the wastewater in collection chamber 22, increasing the amount and speed of wastewater flowing out of collection chamber 22 through water permeable holes 25.

[0078] A drain trough 43 is formed inside the agitator shaft 4, extending along the central axis of the agitator shaft 4. Multiple water inlets 44 are formed on the side of the agitator blade 41 away from the agitator shaft 4, and are evenly spaced along the axial direction of the agitator shaft 4. A drain pipe 16 extends into the drain trough 43 and rotates relative to the agitator shaft 4. A sealing pipe 161 is provided on the drain pipe 16, and the outer peripheral wall of the sealing pipe 161 slides in contact with the peripheral wall of the drain trough 43.

[0079] See Figure 3 and Figure 4 A discharge pipe 16 is fixedly connected to the coagulation cylinder 1, extending into the collection chamber 22, and the stirring roller 2 rotates relative to the discharge pipe 16. A water pump 17 is fixedly connected to the outer wall of the coagulation cylinder 1. The suction port of the water pump 17 is fixed and connected to the discharge pipe 16, and the discharge port of the water pump 17 is fixed and connected to a transmission pipe. In use, the water pump 17 draws out the coagulated material in the collection chamber 22 and transmits the coagulated material to the next processing step through the transmission pipe. The water pump 17 can be a high-pressure pump or a centrifugal pump to ensure effective extraction of the coagulated material.

[0080] See Figure 7 and Figure 8The agitator shaft 4 has a receiving groove 45, which surrounds the discharge pipe 16. The agitator shaft 4 is fixedly connected to a power tooth 46, which is located on the side wall of the receiving groove 45. There are multiple power teeth 46, which are evenly spaced along the circumference. In this embodiment, there are four power teeth 46, which correspond one-to-one with the agitator blade 41.

[0081] See Figure 6 and Figure 8 The outer peripheral wall of the drain pipe 16 has a circumferentially formed "T"-shaped push groove 163. The drain pipe 16 is equipped with a "T"-shaped push block 164, which is slidably connected within the push groove 163. A push spring 165 is installed within the push groove 163, with one end abutting against the push block 164 and the other end abutting against the groove wall of the push groove 163. When the push spring 165 is released elastically, it pushes the push block 164 to slide within the push groove 163 until the push block 164 abuts against the groove wall on one side of the end of the push groove 163. A limiting tooth 166 is fixedly connected to the outer peripheral side of the drain pipe 16. The limiting tooth 166 is adjacent to the push groove 163, and when the push spring 165 pushes the push block 164 to abut against the groove wall on the end side of the push groove 163, the push block 164 is adjacent to the limiting tooth 166. When one of the power teeth 46 is between the push block 164 and the limit tooth 166, the stirring blade 41 corresponding to the power tooth 46 is in a vertically downward state, which is beneficial for extracting the condensate in the collection chamber 22.

[0082] A friction layer 167 is fixedly connected to the wall of the push groove 163. The friction layer 167 is away from the limiting tooth 166. When the push block 164 slides on the friction layer 167, the friction layer 167 slows down the speed at which the push block 164 slides toward the limiting tooth 166. When the agitator shaft 4 rotates, the power tooth 46 pushes the push block 164 to slide away from the limiting tooth 166. At this time, the push block 164 compresses the push spring 165 until the push block 164 approaches the side of the push groove 163 away from the limiting groove. Then the push block 164 slides on the friction layer 167, and the agitator shaft 4 continues to rotate. The push block 164 can slide past the power tooth 46, and the next adjacent power tooth 46 slides on the limiting tooth 166, so that the next adjacent power tooth 46 can slide between the limiting tooth 166 and the push block 164. When the stirring shaft 4 stops rotating, the spring 165 is released elastically, and the pushing block 164 pushes the pushing block 164 to move in the direction of the limiting tooth 166. At this time, the pushing block 164 pushes the power tooth 46, which is between the pushing block 164 and the limiting tooth 166, to slide to abut the power tooth 46, thereby correcting the stirring blade 21 so that the corresponding stirring blade 41 can be in a vertically downward state.

[0083] A sealing pipe 161 is fixedly connected to the outer peripheral wall of the discharge pipe 16. The outer peripheral wall of the sealing pipe 161 is in sliding contact with the peripheral wall of the discharge tank 43. An inlet 162 is formed on the bottom wall of the sealing pipe 161. When one of the stirring blades 21 is in a vertically downward position, the inlet 162 is directly opposite the inlet hole 44 on the vertically downward stirring blade 21, while the inlet holes 44 of the other stirring blades 21 are sealed by the wall of the sealing pipe 161, which helps to improve the effect of extracting coagulants in the collection chamber 22.

[0084] The implementation principle of a high-efficiency coagulation sedimentation device according to an embodiment of this application is as follows:

[0085] The design of the stirring roller 2 enables simultaneous mixing, sedimentation, and filtration, significantly shortening wastewater treatment time. The stirring blades 21 on the roller 2 continuously agitate the wastewater and coagulant during rotation, promoting a thorough reaction between the coagulant and pollutants in the wastewater to form flocs. The design of the sealing plate 24 and the permeable holes 25 prevents the flocs from being collected in the collection chamber 22 during mixing; instead, the wastewater flows back into the coagulation chamber 11 through the permeable holes 25, further promoting floc formation. When the stirring blades 21 move upwards, the sealing plate 24 opens, allowing the flocs to enter the collection chamber 22; when the stirring blades 21 move downwards, the sealing plate 24 closes, preventing floc loss. Finally, the treated flocs are discharged through the drain pipe 16 and the water pump 17, while the drain pipe 16 discharges the wastewater from the coagulation chamber 11.

[0086] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
