Description

Technical Field

[0001] The present application relates to the technical field of printing wastewater treatment, and in particular to a printing wastewater treatment device. Background Art

[0002] In the process of printing wastewater treatment, flocculation and sedimentation are generally used for pretreatment. The "printing wastewater comprehensive treatment circulation device" disclosed in the existing patent documents includes a sewage drainage pipe, a collection tank, a UASB reactor, a filter, a clear water tank, a sludge tank, and also includes a flocculation and sedimentation treatment machine and an activated carbon adsorption layer.

[0003] The flocculation sedimentation treatment machine integrates the two processes of flocculation reaction and sedimentation separation, reducing equipment investment and industrial land. However, both flocculation reaction and sedimentation separation take a long time. In particular, after the sediment is settled, it takes a long time to discharge, and a large amount of liquid will remain in the sediment, making the subsequent sedimentation treatment process extremely inconvenient, thereby reducing the treatment efficiency of wastewater. Summary of the invention

[0004] In order to improve the efficiency of wastewater treatment, the present application provides a printing wastewater treatment device.

[0005] The present application provides a printing wastewater treatment device, which adopts the following technical solution: A printing wastewater treatment device comprises a machine body and a flocculation device arranged on the machine body, wherein a first sedimentation chamber and a second sedimentation chamber are connected to each other and arranged in an upper and lower interval at the bottom wall of the machine body, and the machine body is provided with a sewage discharge mechanism, and the sewage discharge mechanism comprises: A sewage pipe is arranged on the bottom of the machine body and is connected to the second sedimentation chamber and is provided with a sewage valve for opening and closing; Two push plates, the bottom of which is rotatably arranged on the machine body and located at the connection between the first sedimentation chamber and the second sedimentation chamber, and the tops of the two push plates are arranged upward and abut against the inner wall of the machine body for positioning when the sediment is being precipitated; A rotating assembly, used for driving the two push plates to rotate; The drainage component is connected with the machine body and the sewage pipe and is used to discharge the liquid in the machine body and the sewage pipe; when sewage needs to be discharged, the two push plates push the sediment in the first sedimentation chamber to move to the second sedimentation chamber and allow the liquid to be discharged through the drainage component, the drainage component is closed, the sewage valve is opened, the two push plates continue to rotate to the second sedimentation chamber and are used to push the sediment to be discharged through the sewage pipe until it rests on the side wall of the second sedimentation chamber, and finally, the two push plates rotate back to their original positions.

[0006] By adopting the above technical solution, sewage is added to the body, and the sewage first passes through the flocculation device to form flocculent sediments in the sewage. The sediments are precipitated into the second sedimentation chamber for storage under the action of gravity. As the sediments increase, the sediments gradually accumulate and enter the first sedimentation chamber for storage until the sewage treatment is completed.

[0007] The drainage component is opened, and the rotating component is started to push the tops of the two push plates to rotate downward. During the rotation of the two push plates, the sediment deposited in the first sedimentation chamber is pushed to move toward the second sedimentation chamber. During the movement, the liquid above the sediment moves out through the gap between the two push plates, and then the liquid is discharged through the drainage component until the push plates are in a horizontal state and stop. In addition, during the rotation of the push plates, the sediment enters the second sedimentation chamber and is squeezed, so that the liquid in the sewage pipe can also be discharged through the drainage component; at the same time, even if there is less sediment in the first sedimentation chamber, the sediment can be squeezed into the second sedimentation chamber through the rotation of the push plates.

[0008] When the liquid is discharged, the drainage component is closed and the drain valve is opened. The sediment can be discharged through the drain pipe under the action of gravity. At the same time, the two push plates continue to rotate into the second sedimentation chamber. The push plates can continue to push the sediment to accelerate through the drain pipe until the push plates rest against the side wall in the second sedimentation chamber for positioning. Then the rotating component starts to drive the two push plates back to their original position until the push plates rest against the side wall of the first sedimentation chamber and stop rotating. Finally, the drain valve is closed to continue the next sewage treatment.

[0009] The two push plates push the sediment to move, thereby achieving a squeezing effect, so that the liquid in the sediment is discharged through the drainage component. At the same time, the liquid in the second sedimentation chamber and the sewage pipe can also be discharged through the drainage component, thereby greatly reducing the amount of water in the sediment and improving the convenience of subsequent sediment treatment. After the two push plates are transferred to the second sedimentation chamber, they can also push the sediment to accelerate through the sewage pipe, thereby saving the time for sediment discharge and further improving the sewage treatment efficiency.

[0010] Furthermore, when the push plate contacts the side wall of the second sedimentation chamber, the sediment adhered to the second sedimentation chamber can be squeezed out to achieve cleaning. When the push plate contacts the side wall of the first sedimentation chamber, the sediment adhered to the first sedimentation chamber and the push plate can be squeezed out to achieve cleaning, thereby reducing the adverse effects of the sediment adhered to the body and the push plate on subsequent treatment, thereby further accelerating the sewage treatment efficiency.

[0011] Optionally, a avoidance space is formed between the two push plates for liquid to flow out and for avoiding the sediment when they approach each other. One of the push plates is provided with a positioning member. When the two push plates are turned to a horizontal state, the positioning member abuts against the other push plate to prevent the sediment from moving out through the avoidance space.

[0012] By adopting the above technical solution, the avoidance space is used to achieve avoidance during the rotation of the two pushing plates. At the same time, when the pushing plates are rotated to a horizontal state, the positioning pieces on the pushing plates abut against the other pushing plates to achieve the blocking of the avoidance space. During the rotation of the positioning pieces, the sediment can also be pushed to move toward the second sedimentation chamber, thereby further improving the squeezing and pushing effect on the sediment and further improving the sewage treatment efficiency.

[0013] Optionally, the two ends of the two push plates are against the first sedimentation chamber or the second sedimentation chamber and are used to scrape off the adhered sediment. When the push plates are set upward, they are tightly against the side wall of the first sedimentation chamber or when they are set downward, they are tightly against the side wall of the second sedimentation chamber and are used to squeeze out the sediment adhered to the push plates.

[0014] By adopting the above technical solution, the rotation of the pushing plate can cause the sediment adhered to the first sedimentation chamber or the second sedimentation chamber to fall and be discharged, and at the same time, the sediment adhered to the first sedimentation chamber and the second sedimentation chamber can be squeezed out and cleaned. Therefore, the pushing plate can clean the adhered sediment while squeezing, so that more sediment is discharged, which greatly improves the sewage treatment efficiency.

[0015] Optionally, the rotating assembly includes: Two gears, arranged on two push plates; Two racks are slidably arranged on the machine body and mesh with the two gears; The pusher is used to drive the two racks to move closer to or away from each other.

[0016] By adopting the above technical solution, the pusher drives the two racks to move closer to or away from each other, and the movement of the two racks drives the two gears to rotate, thereby realizing the simultaneous rotation of the two push plates.

[0017] Optionally, the drainage component includes: A drainage pipe 1 is arranged on the machine body and communicated with the second sedimentation chamber. When the push plate is turned to a horizontal state, the connection between the drainage pipe 1 and the second sedimentation chamber is located above the push plate; Drain pipe 2 is arranged on the sewage pipe and is arranged downwardly inclined. A water filter net is arranged on the drain pipe 2 to block the passage of sediment and allow the passage of liquid. A first valve body and a second valve body for controlling opening and closing are respectively arranged on the drain pipe 1 and the drain pipe 2; The collecting box is connected to the drain pipe 1 and the drain pipe 2 and is used for collecting liquid.

[0018] By adopting the above technical solution, the first valve body and the second valve body are opened, and the liquid in the second sedimentation chamber is discharged into the collection box through the drain pipe one. At the same time, the liquid in the sewage pipe passes through the water filter net and then enters the collection box through the drain pipe two for collection, thereby realizing the collection of the liquid. At the same time, the water filter net can prevent the sediment from moving out, and as the subsequent sediment is discharged, the sediment adhered to the water filter net is removed together, thereby accelerating the speed of the liquid passing through the drain pipe two during the subsequent sewage treatment, thereby ensuring the drainage effect during the subsequent sewage treatment.

[0019] Optionally, a first chamber and a second chamber that are independent of each other are formed on the collection box, and the drain pipe 1 is connected to both the first chamber and the second chamber through a three-way valve, and the three-way valve controls the connection between the drain pipe 1 and the first chamber or the second chamber.

[0020] By adopting the above technical solution, there is still a risk that some sediment will move to the top of the pushing plate during the rotation of the pushing plate. Therefore, in the process of the pushing plate rotating from rotation to horizontal, the three-way valve controls the drain pipe 1 to be connected with the first chamber, so that the liquid containing the removed sediment first flows through the drain pipe 1 to the first chamber for storage. After a period of time, the three-way valve controls the drain pipe 1 to be connected with the second chamber, so that the liquid flows to the second chamber for storage, so that the liquid in the first chamber can be further processed separately, which can ensure the processing effect while also improving the processing efficiency.

[0021] Optionally, the flocculation device comprises: A stirring rod is rotatably disposed on the top of the machine body and is provided with stirring blades for stirring; A plurality of grid frames are arranged in a circular array around the axis of the stirring rod and are arranged to slide radially along the stirring rod and can move vertically, and the grid frames are provided with a plurality of through holes for liquid to pass through; The driving mechanism is used to drive the stirring rod to rotate and make the multiple grille frames move horizontally and vertically at the same time.

[0022] By adopting the above technical solution, the driving mechanism drives the stirring rod to rotate, and the rotation of the stirring rod drives the stirring blade to rotate, and the stirring blade stirs the liquid. At the same time, multiple grille frames move back and forth horizontally and vertically at the same time. The grille frames can prevent the liquid from vortexing, so that the debris in the liquid can form sediment under the action of the flocculant. The horizontal and vertical movement of the grille frames can accelerate the flocculation speed of impurities in the liquid, thereby further improving the sewage treatment efficiency.

[0023] Optionally, the driving mechanism includes: A rotating member, used for driving the stirring rod to rotate; A driving block is arranged on the stirring rod and has a plurality of interconnected arc surfaces arranged in a circumferential array around the axis of the stirring rod, wherein the arc surfaces include mutually connected and outwardly protruding protrusions and inwardly recessed recesses; A driving member, which is arranged on the plurality of grid frames and is driven by the driving block to reciprocate vertically; A plurality of elastic components are arranged on the grille frame and used for driving the grille frame to lean against the arc surface.

[0024] By adopting the above technical solution, the rotating member drives the stirring rod to rotate, and the rotation of the stirring rod causes the driving block to rotate, and the grille frame is pressed against the arc surface under the action of the elastic component. The position of the grille frame changes when it passes through the protrusion and the recessed part, so that the grille swings back and forth wildly. At the same time, the driving member causes multiple grille frames to reciprocate vertically, so that the grille frames can reciprocate in both horizontal and vertical directions. Therefore, while preventing the liquid from vortexing, it can also accelerate the flocculation speed of impurities in the liquid, thereby improving the sewage treatment efficiency.

[0025] Optionally, a driving groove with gradually changing height and connected end to end is opened on the arc surface along the side wall of the arc surface, and the driving member is a driving column arranged on the grille frame and slidably arranged on the driving groove, and the driving block rotates to drive the driving column and the grille frame to reciprocate vertically.

[0026] By adopting the above technical solution, the driving column slides on the driving groove, and the arc surface rotates to rotate the driving groove, thereby causing the driving column and the grille frame to reciprocate up and down. At the same time, since the driving groove is opened along the surface of the arc surface, the rotation of the driving groove also causes the grille frame to reciprocate in the horizontal direction, thereby causing the grille frame to reciprocate up and down and horizontally.

[0027] Optionally, the elastic component includes: A moving block is vertically slidably arranged on the machine body and is provided with a moving groove; A guide block is arranged on the grid frame and is slidably arranged on the moving groove along the axis of the stirring rod; The spring is arranged on the guide block and presses against the bottom of the moving groove and is in a compressed state.

[0028] By adopting the above technical solution, when the grille frame moves, the moving block is driven to move vertically, and the spring pushes the grille frame to rest against the arc surface, so that the grille frame can move on the moving block in the horizontal direction, thereby realizing the vertical and horizontal movement of the grille frame; at the same time, the spring is located in the moving groove, thereby reducing the probability of sewage damaging the spring.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. The two push plates push the sediment to move, and the extrusion effect is achieved in the process, so that the liquid in the sediment is discharged through the drainage component. At the same time, the liquid in the second sedimentation chamber and the sewage pipe can also be discharged through the drainage component, thereby greatly reducing the amount of water in the sediment and improving the convenience of subsequent sediment treatment. After the two push plates are transferred to the second sedimentation chamber, they can also push the sediment to accelerate through the sewage pipe, thereby saving the time of sediment discharge and further improving the efficiency of sewage treatment.

[0030] 2. When the push plate contacts the side wall of the second sedimentation chamber, the sediment adhered to the second sedimentation chamber can be squeezed out and cleaned. When the push plate contacts the side wall of the first sedimentation chamber, the sediment adhered to the first sedimentation chamber and the push plate can be squeezed out and cleaned. This reduces the adverse effects of the sediment adhered to the body and the push plate on subsequent treatment, thereby further accelerating the sewage treatment efficiency.

DETAILED DESCRIPTION

[0033] The present application is described in further detail below.

As the sediments increase, the sediments accumulate in the first sedimentation chamber 11, and the sewage discharge mechanism 5 is used to squeeze the sediments and discharge the liquid at the same time, and then discharge the sediments to complete the sewage treatment.

[0036] Reference Figure 1 and Figure 3 The flocculation device 2 includes a stirring rod 21, a plurality of grid frames 22, and a driving mechanism 3. The stirring rod 21 is coaxially rotatably mounted on the top upper surface of the body 1, and the bottom of the stirring rod 21 extends vertically downward into the body 1. A plurality of stirring blades 23 for stirring are arranged at intervals on the stirring rod 21; a mounting ring 13 is coaxially fixedly mounted on the inner wall of the body 1, and a plurality of grid frames 22 are arranged in a circular array around the axis of the stirring rod 21 and spliced ​​to form a circular ring structure. A plurality of through holes that vertically penetrate the grid frames 22 and are used for sediment to pass through are arranged at intervals on the grid frames 22.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The driving mechanism 3 is used to drive the stirring rod 21 to rotate and make multiple grille frames 22 move horizontally and vertically at the same time. The driving mechanism 3 includes a rotating member 31, a driving block 32, a driving member 33 and multiple elastic components 4. The rotating member 31 is a servo motor. The rotating member 31 is fixedly installed on the upper surface of the body 1, and the output shaft of the rotating member 31 is connected to the stirring rod 21 and is used to drive the stirring rod 21 and the stirring blade 23 to rotate.

[0038] The driving block 32 is coaxially fixedly mounted on the stirring rod 21 and is located on the inner side of the plurality of grille frames 22. A plurality of interconnected arc surfaces 34 are arranged on the outer wall of the driving block 32 in a circular array around the axis of the stirring rod 21. Each arc surface 34 includes a protrusion 35 and a recess 36 which are interconnected and arc-shaped. The protrusion 35 protrudes outward and the recess 36 is recessed inward. At the same time, a driving groove 37 is opened on the surface of the arc surface 34 along the arc surface 34. The height of the driving groove 37 gradually changes. The height of the driving groove 37 gradually increases to the highest point and then gradually decreases and is connected end to end.

[0039] There are multiple driving members 33 and they are respectively located on multiple grille frames 22, and the driving members 33 are driving columns fixedly installed on the side wall of the grille frame 22 close to the driving block 32. The diameter of the driving column is the same as the width of the driving groove 37, and the driving column is slidably installed on the driving groove 37; multiple elastic components 4 are arranged in a one-to-one correspondence with the multiple grille frames 22, and the elastic component 4 is arranged on one end of the grille frame 22 away from the driving member 33, and under the action of the elastic force, the driving column is pushed to always rest against the driving groove 37 for positioning.

[0040] The stirring rod 21 rotates to drive the stirring blade 23 to rotate, and flocculants are added to the sewage, so that impurities in the sewage form flocculent sediments; the stirring rod 21 rotates to drive the driving block 32, the arc surface 34, and the driving groove 37 to rotate, and the driving column is slidably installed on the driving groove 37. When the driving column moves from the driving groove 37 located at the recessed portion 36 to the driving groove 37 located at the protruding portion 35, the driving column and the grille frame 22 are driven away from the stirring rod 21. Conversely, when the driving column moves from the driving groove 37 located at the protruding portion 35 to the driving groove 37 located at the recessed portion 36, the driving column and the grille frame 22 are driven to approach the stirring rod 21, so that the grille frame 22 reciprocates horizontally. At the same time, the different heights of the driving groove 37 also make the grille frame 22 reciprocate vertically, so as to realize the reciprocating movement of the grille frame 22 in both horizontal and vertical directions. The grille frame 22 prevents the formation of a vortex when the sewage is stirred, and the reciprocating movement of the grille frame 22 accelerates the deposition of flocculent sediments and accelerates the sewage treatment efficiency.

[0041] The elastic component 4 includes a moving block 41, a guide block 42, and a spring 43. The moving block 41 is vertically slidably installed on the inner wall of the mounting ring 13, and a moving groove 44 is opened on the side wall of the moving block 41 close to the grille frame 22 along the radial direction of the stirring rod 21; the guide block 42 is fixedly installed on the side wall of the grille frame 22 close to the moving groove 44, and the guide block 42 is radially slidably installed on the moving groove 44 along the stirring rod 21, and the cross-section of the guide block 42 is square and the guide block 42 and the grille frame 22 can only move horizontally but not rotate; the spring 43 is fixedly installed on one end of the guide block 42 located in the moving groove 44, and the other end of the spring 43 presses on the bottom of the moving groove 44 for positioning and is in a compressed state, so that the drive column presses on the drive groove 37 for positioning.

[0042] Reference Figure 1 , Figure 2 , Figure 5 The sewage discharge mechanism 5 includes a sewage discharge pipe 51, two push plates 52, a rotating assembly 53, and a drainage assembly 6. The cross-sections of the first sedimentation chamber 11 and the second sedimentation chamber 12 are both trapezoidal, and the top cross-sectional area is larger than the bottom cross-sectional area. The top of the second sedimentation chamber 12 is the same as the bottom of the first sedimentation chamber 11 and is connected to each other; the sewage discharge pipe 51 is fixedly installed at the bottom of the body 1, and the sewage discharge pipe 51 is vertically downwardly arranged and connected to the second sedimentation chamber 12. A sewage discharge valve 511 for controlling opening and closing is fixedly installed on the sewage discharge pipe 51.

[0043] The bottoms of the two push plates 52 are rotatably installed at the two ends of the connection between the first sedimentation chamber 11 and the second sedimentation chamber 12 through the rotating shaft 521. The tops of the two push plates 52 are tilted upward and tightly pressed against the inner wall of the first sedimentation chamber 11 for positioning. After the two push plates 52 are rotated, they can also be rotated into the second sedimentation chamber 12 and tightly pressed against the side wall of the second sedimentation chamber 12 for positioning. At the same time, the top of the second sedimentation chamber 12 and the first sedimentation chamber 11 have the same width, so that when the two push plates 52 rotate, the two ends can be against the opposite side walls of the first sedimentation chamber 11 or the opposite side walls of the second sedimentation chamber 12, so as to scrape off the sediment adhering to the first sedimentation chamber 11 and the second sedimentation chamber 12.

[0044] The top of one of the push plates 52 is fixedly mounted on the positioning piece 522, and a avoidance space is formed between the two push plates 52 for liquid to flow out and for avoiding the position when rotating. When the two push plates 52 are rotated to a horizontal state, the positioning piece 522 abuts against the other push plate 52 and blocks the avoidance space, thereby preventing sediment from passing through the avoidance space.

[0045] The rotating assembly 53 is arranged on the machine body 1 and is used to drive the two push plates 52 to rotate. The rotating assembly 53 includes two gears 54, two racks 55 and a pusher 56. The two rotating shafts 521 extend to the outside of the machine body 1. The two gears 54 are key-connected to the rotating shafts 521 and are located outside the machine body 1. The two racks 55 are horizontally slidably installed on the outer wall of the machine body 1, and the two racks 55 are respectively meshed with the two gears 54. The pusher 56 is a double-headed electric push rod. The pusher 56 is fixedly installed on the outer wall of the machine body 1, and the two piston rods of the pusher 56 are respectively fixedly connected with the two racks 55. The pusher 56 drives the two racks 55 to move closer to or away from each other, thereby driving the two push plates 52 to rotate simultaneously.

[0046] The drainage component 6 is connected to the body 1 and the sewage pipe 51 and is used to discharge the liquid in the body 1 and the sewage pipe 51. The drainage component 6 includes a drainage pipe 1 61, a drainage pipe 2 62 and a collecting box 7. The drainage pipe 1 61 is fixedly installed on the body 1 and is tilted downward. When the push plate 52 is rotated to a horizontal state, the connection point between the drainage pipe 1 61 and the body 1 is located above the rotating shaft 521 and the push plate 52, and is used to discharge the liquid above the push plate 52 at this time; the drainage pipe 2 62 is detachably installed on the sewage pipe 51 through a flange, and the drainage pipe 2 62 is tilted downward. A water filter net is installed at the connection between the drainage pipe 2 62 and the sewage pipe 51. At the same time, when the drainage pipe 2 62 is separated from the sewage pipe 51, the water filter net can also be removed for cleaning or replacement. The drainage pipe 1 61 and the drainage pipe 2 62 are respectively fixedly installed with a first valve body 76 and a second valve body 77 for controlling opening and closing.

[0047] The collecting box 7 is connected to the drain pipe 1 61 and the drain pipe 2 62 and is used for collecting liquid. A partition 71 is fixedly installed on the inner wall of the collecting box 7. The partition 71 divides the collecting box 7 into a first chamber 72 and a second chamber 73 which are independent of each other. The space in the first chamber 72 is smaller than the space in the second chamber 73. The drain pipe 2 62 is connected to the second chamber 73. A first tube body 74 and a second tube body 75 which are respectively connected to the first chamber 72 and the second chamber 73 are fixedly installed on the collecting box 7. The first tube body 74 and the second tube body 75 are connected to the drain pipe 1 61 through a three-way valve 78. The three-way valve 78 is used to control the connection between the drain pipe 1 61 and the first tube body 74 or the second tube body 75, so as to realize that the three-way valve 78 controls the connection between the drain pipe 1 61 and the first chamber 72 or the second chamber 73.

[0048] During the rotation of the two push plates 52, the sediment can be pushed toward the second sedimentation chamber 12. At the same time, the liquid moves upward to the top of the push plate 52 through the avoidance space. At this time, some sediment will be moved out through the avoidance space and mixed into the discharged liquid. Then, the sediment will move down and approach the drain pipe 61 under the action of gravity. Therefore, when drainage starts, the three-way valve 78 controls the connection between the drain pipe 61 and the first chamber 72, and the liquid mixed with the sediment located above the rotating shaft 521 can flow to the first chamber 72 for storage through the drain pipe 61 and the first tube body 74. At this time, the liquid squeezed into the sewage pipe 51 can be moved to the second chamber 73 for storage through the drain pipe 2 62 after passing through the water filter net. After a period of time, the three-way valve 78 controls the drain pipe 1 61 to be connected with the second chamber 73, and at the same time, the liquid passing through the drain pipe 1 61 and the drain pipe 2 62 flows to the second chamber 73 for storage, so that the liquid in the first chamber 72 can be processed again, which can ensure the sewage effect while also improving the treatment efficiency.

[0049] The working principle of the embodiment of the present application is as follows: Sewage and flocculant are added into the body 1, and the rotating member 31 starts to drive the stirring rod 21 and the stirring blade 23 to rotate to stir the sewage. The stirring rod 21 rotates to drive multiple grille frames 22 to reciprocate in both vertical and horizontal directions at the same time. The grille frames 22 can prevent the sewage from forming a vortex, and the movement of the grille frames 22 can accelerate the impurities to form flocculent sediments, so that the sediments are deposited downward into the second sedimentation chamber 12 under the action of gravity. As the sediments increase, the sediments accumulate in the first sedimentation chamber 11.

[0050] As the sewage treatment is completed, the rotating member 31 stops rotating, and the pushing member 56 drives the two pushing plates 52 to rotate downward. When the two pushing plates 52 rotate, they push the sediment in the first sedimentation chamber 11 to move toward the second sedimentation chamber 12, and squeeze the sediment during the pushing process until the two pushing plates 52 turn to a horizontal state, and the positioning member 522 is used to seal the avoidance space. When the pushing plates 52 rotate, the first valve body 76 and the second valve body 77 open the drain pipe 1 61 and the drain pipe 2 62, and the liquid flows through the drain pipe 1 61 and the drain pipe 2 62 to the collection box 7 for collection, so that the liquid in the sediment can flow out quickly until the liquid is drained, and the first valve body 76 and the second valve body 77 are closed.

[0051] The drain valve 511 is opened, and the sediment is discharged through the drain pipe 51. At the same time, the push member 56 continues to start and drives the two push plates 52 to continue to rotate downward into the second sedimentation chamber 12. When the two push plates 52 rotate, they can push the sediment to accelerate through the drain pipe 51 until the two push plates 52 are against the side wall of the second sedimentation chamber 12 for positioning. When the sediment is discharged, the drain valve 511 is closed, and the push member 56 drives the two push plates 52 to rotate upward until they are tightly against the side wall of the first sedimentation chamber 11 for positioning, thereby greatly improving the sewage treatment efficiency.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
