Description

TECHNICAL FIELD

[0001] The present application relates to the field of reactors, in particular to a decolorization reactor based on ozone catalytic reaction. BACKGROUND

[0002] In sewage treatment, the strong oxidizing property of ozone is generally used to break the molecular chain of macromolecular organic matter, so as to change it into small molecular organic matter, and also to oxidize part of the organic matter in water into simple inorganic matter, while reducing COD.

[0003] At present, the related technology discloses a decolorization reactor, which comprises a tank body, and a filter screen, a support plate and a catalyst layer are sequentially arranged in the tank body from bottom to top. The support plate is provided with a plurality of through holes for sewage to pass through. The tank body is provided with an aeration assembly, an exhaust pipe, a sewage pipe and a drainage pipe. The aeration assembly sends ozone into the space below the filter screen in the tank body, and the sewage pipe sends sewage into the space below the filter screen in the tank body. Then the ozone and the sewage are mixed to react, and the catalyst layer is beneficial to accelerate the reaction speed of the ozone and the sewage. After the sewage and the ozone react, treated water and oxygen are formed, the treated water is discharged from the drainage pipe, and the ozone and the oxygen are discharged from the exhaust pipe. The filter screen is used to filter impurities in the sewage, so as to reduce the amount of impurities entering the catalyst layer. The through holes of the support plate are used for the sewage to pass through, and the catalyst layer cannot fall down through the through holes.

[0004] According to the related technology in the above, the inventor believes that after the sewage flows through the catalyst layer, part of the impurities will be left on the bottom side of the catalyst layer, so that the bottom side of the catalyst layer is blocked, and then the sewage and the ozone are hindered to pass through the catalyst layer. SUMMARY

[0005] In order to facilitate the sewage and the ozone to pass through the catalyst layer, the present application provides a decolorization reactor based on ozone catalytic reaction.

[0006] The decolorization reactor based on ozone catalytic reaction provided by the present application adopts the following technical scheme:

[0007] The utility model provides a kind of decolorization reactor based on ozone catalytic reaction, including tank body, the tank body bottom side tank body is equipped with sewage pipe, the tank body top side tank body is equipped with drain pipe, the inside of the tank body is equipped with filter screen, support plate and catalyst layer in turn at least from below, the top side of the tank body is fixedly installed with exhaust pipe, the tank body is equipped with aeration assembly, the aeration assembly is used to send ozone to the space of tank body below filter screen, the support plate top surface is fixedly installed with guide pipe, the support plate bottom surface is fixedly installed guide cover, the guide cover and support plate are all opened with multiple first through holes for sewage, the guide pipe is worn with lifting rod, the support plate is opened with first lifting opening for lifting rod slidingly worn, the rod body of the lifting rod is articulated with multiple pusher rods, the support plate is opened with multiple second lifting openings for pusher rod to be worn, the second lifting opening is communicated with first lifting opening, the tank body is equipped with lifting mechanism, the lifting mechanism is used to drive lifting rod to lift, the pipe body of the guide pipe is opened with multiple feeding ports, the feeding port is used for catalyst layer to enter guide pipe inside.

[0008] By adopting the above technical scheme, when the pusher rod enters the inside of the guide cover with the lifting rod, the pusher rod rotates away from the lifting rod under the action of gravity, so that the pusher rod is unfolded. Then the lifting mechanism drives the lifting rod to rise, and the pusher rod enters the inside of the guide pipe from the second lifting opening. The lifting mechanism drives the lifting rod to continue to rise, and the pusher rod pushes out the catalyst layer located in the inside of the guide pipe. The catalyst layer pushed out from the inside of the guide pipe moves to the top side of the catalyst layer outside the guide pipe, and at the same time, the catalyst layer outside the guide pipe fills up after entering the inside of the guide pipe from the feeding port. After the inside of the guide pipe is filled with the catalyst layer, the lifting mechanism drives the lifting rod to descend, and the pusher rod is blocked by the catalyst layer, so that the pusher rod rotates upward and is attached to the rod body of the lifting rod, thereby facilitating the lifting rod to drive the pusher rod to return to the inside of the guide cover. By repeatedly lifting the lifting rod through the lifting mechanism, the catalyst layer is continuously moved, thereby reducing the occurrence of the blockage of the bottom side of the catalyst layer. By reducing the occurrence of the blockage of the bottom side of the catalyst layer, it is convenient for the sewage and ozone to pass through the catalyst layer.

[0009] Optionally, the aeration assembly includes a shunt pipe, an aeration head, and a gas supply pipe. The shunt pipe is fixedly installed on the inner bottom wall of the tank body. The two ends of the shunt pipe are connected to each other. There is at least one aeration head. The aeration head is fixedly installed on the top side of the shunt pipe body. The aeration head sprays gas upward. One end of the gas supply pipe is fixedly connected to the shunt pipe body. The other end of the gas supply pipe is fixedly penetrated through the top side of the tank body. The end of the gas supply pipe located outside the tank body is used for the ozone to enter.

[0010] By adopting the above technical scheme, the ozone enters the inside of the gas supply pipe, and the gas supply pipe sends the ozone into the inside of the shunt pipe. Then the ozone in the inside of the shunt pipe is sprayed out from the aeration head, thereby facilitating the ozone to be sent to the space of the tank body below the screen.

[0011] Optionally, the lifting rod is provided with a ring groove, an installation ring is arranged inside the ring groove, a connecting piece is fixedly installed between the inner wall of the installation ring and the groove bottom of the ring groove, one end of the pushing rod is provided with an installation hole for the installation ring to pass through, and the inner side wall above the ring groove is provided with a plurality of receiving grooves for the pushing rod to enter after being upwardly rotated.

[0012] By adopting the above technical scheme, the pushing rod is rotated on the installation ring, and the receiving groove facilitates the pushing rod to enter after being upwardly rotated, so that the rod body of the lifting rod remains flat when the lifting rod is lowered, thereby reducing the situation that the pushing rod crushes the catalyst layer. When the pushing rod is downwardly rotated, the pushing rod and the inner side wall below the ring groove are mutually clamped, thereby playing a role of limiting the rotation angle of the pushing rod, and thereby facilitating the pushing rod to push the catalyst layer inside the guide pipe out.

[0013] Optionally, the inner side wall below the ring groove is gradually lowered and arranged in an inclined manner from the groove bottom to the groove opening.

[0014] By adopting the above technical scheme, when the pushing rod is unfolded, the pushing rod abuts against the inner side wall below the ring groove. Influenced by the inclination of the inner side wall below the ring groove, when the pushing rod is unfolded, the end of the pushing rod close to the lifting rod to the other end is gradually lowered and arranged in an inclined manner, thereby facilitating the catalyst layer to fall off from the pushing rod.

[0015] Optionally, the lifting mechanism comprises a motor, a rotating rod, a winding disc and a first pull rope, the body of the motor is fixedly installed on the side wall of the tank body, the rotating shaft of the motor is fixedly penetrated through the side wall of the tank body, the rotating rod is horizontally arranged inside the tank body, one end of the rotating rod is rotatably inserted into the inner side wall of the tank body, the other end of the rotating rod is fixedly connected with the rotating shaft of the motor, the winding disc is fixedly installed on the rotating rod, one end of the first pull rope is fixedly connected with the winding disc, and the other end of the first pull rope is fixedly connected with the top end of the lifting rod.

[0016] By adopting the above technical scheme, when it is necessary to drive the lifting rod to lift, the motor is started. When the motor drives the winding disc to positively rotate through the rotating rod, the winding disc winds the first pull rope, and the lifting rod rises; when the motor drives the winding disc to reversely rotate through the rotating rod, the winding disc unwinds the first pull rope, and the lifting rod descends under the action of gravity, thereby facilitating the driving of the lifting rod to lift.

[0017] Optionally, the lifting mechanism comprises a first floating block, a second pull rope and a flow adjusting assembly, the first floating block is located inside the tank body, the first floating block is located above the catalyst layer, one end of the second pull rope is fixedly connected with the first floating block, the other end of the second pull rope is fixedly connected with the top end of the lifting rod, and the flow adjusting assembly is installed inside the tank body and is used for adjusting the water discharge amount of the drain pipe.

[0018] By adopting the technical scheme, the flow regulating assembly reduces the water discharge capacity of the drain pipe, so that the sewage level in the tank body continuously rises. The sewage level in the tank body rises, and the first floating block pulls the lifting rod up through the second pull rope. After the push rod pushes the catalyst layer in the guide pipe out, the flow regulating assembly increases the water discharge capacity of the drain pipe, so that the sewage level in the tank body continuously decreases. The lifting rod automatically descends under the action of gravity, thereby facilitating the driving of the lifting rod to rise and fall.

[0019] Optionally, the flow regulating assembly comprises a sliding rail, a shielding plate, a counterweight, a second floating block and a magnetic block, the sliding rail is fixedly installed on the inner side wall of the tank body, the sliding rail has two, the drain pipe is located between the two sliding rails, the shielding plate is slidably installed on the sliding rail, the shielding plate is used for shielding one end of the drain pipe located in the tank body, the shielding plate has a hollow structure, the second floating block is fixedly installed on the top side of the shielding plate, the counterweight is fixedly installed on one side of the shielding plate away from the drain pipe, and the magnetic block is fixedly installed on the inner top wall of the tank body.

[0020] By adopting the technical scheme, the counterweight drives the shielding plate to slide downward, the shielding plate blocks one end of the drain pipe located in the tank body, thereby reducing the amount of sewage discharged by the drain pipe, and further causing the sewage level in the tank body to continuously rise. After the sewage level rises, the second floating block drives the shielding plate to rise, and the magnetic block attracts the second floating block. After the second floating block drives the shielding plate to rise, one end of the drain pipe located in the tank body is opened, thereby causing the sewage in the tank body to be discharged from the drain pipe, the water level in the tank body decreases, and further causing the buoyancy of the second floating block and the shielding plate to continuously decrease. When the total weight of the shielding plate, the counterweight and the second floating block is greater than the sum of the buoyancy provided by the sewage and the magnetic force of the magnetic block, the shielding plate re-descends, thereby shielding one end of the drain pipe located in the tank body, and further facilitating the adjustment of the sewage level in the tank body.

[0021] Optionally, the guide pipe is fixedly sleeved with a plurality of first material guiding ring plates, the plurality of first material guiding ring plates are spaced apart from each other, the circumferential side of the first material guiding ring plate is surrounded by the inner side wall of the tank body to form a first material falling port, the first material guiding ring plate is gradually lowered from inside to outside and is arranged in an inclined manner, a second material guiding ring plate is arranged between adjacent two first material guiding ring plates, the circumferential side of the second material guiding ring plate is fixedly connected with the inner side wall of the tank body, the inner side wall of the second material guiding ring plate and the pipe body of the guide pipe surround a second material falling port, and the second material guiding ring plate is gradually lowered from outside to inside and is arranged in an inclined manner.

[0022] By adopting the technical scheme, under the guidance of the first material guiding ring plate and the second material guiding ring plate, part of the top side of the catalyst layer continuously moves downward, and part of the bottom side of the catalyst layer enters the inside of the guide pipe, thereby reducing the occurrence of the blockage of the bottom side of the catalyst layer.

[0023] Optionally, the first material guiding ring plate and the second material guiding ring plate are both provided with a plurality of second through holes for sewage to pass through.

[0024] By adopting the above technical scheme, the second through hole facilitates the passing of sewage and ozone, thereby reducing the occurrence of the situation that ozone forms bubbles below the first material guiding ring plate and the second material guiding ring plate.

[0025] Optionally, the support plate is arranged in a tilt manner with the position of the guide pipe as the center and gradually rising to the periphery.

[0026] By adopting the above technical scheme, the part of the catalyst layer at the bottom side is guided by the support plate, thereby facilitating the part of the catalyst layer at the bottom side to enter the inside of the guide pipe.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0028] 1. The driving mechanism drives the lifting rod to repeatedly rise and fall, the lifting rod repeatedly pushes the catalyst layer in the inside of the guide pipe out through the pushing rod, and then the catalyst layer outside the guide pipe enters the inside of the guide pipe from the feeding port, so that the catalyst layer continuously moves, the situation that the bottom side of the catalyst layer is blocked is reduced, and then the passing of sewage and ozone through the catalyst layer is facilitated;

[0029] 2. When the lifting rod descends, the pushing rod is hindered by the catalyst layer to rotate upward and then enters the inside of the receiving groove, so that the rod body of the lifting rod remains flat, and then the situation that the catalyst layer is crushed is reduced;

DETAILED DESCRIPTION

[0040] The following will be described in detail with reference to the accompanying drawings. Figures 1-7 The present application will be further described in detail.

[0041] The embodiment of the present application discloses a decoloring reactor based on ozone catalytic reaction.

[0042] Embodiment 1.

[0043] With reference to Figure 1 A decoloring reactor based on ozone catalytic reaction comprises a tank body 1, a sewage pipe 2 is mounted on the tank body 1 at the bottom side, sewage is sent into the inside of the tank body 1 from the sewage pipe 2. The tank body 1 is provided with an aeration assembly 5.

[0044] With reference to Figure 2 , Figure 3The aeration assembly 5 comprises a shunt pipe 51, an aeration head 52 and a gas delivery pipe 53. The shunt pipe 51 is fixedly installed on the inner bottom wall of the tank body 1, and the two ends of the shunt pipe 51 are connected to each other. The aeration head 52 is at least one, and the aeration head 52 is fixedly installed on the top side of the shunt pipe 51. The aeration head 52 sprays ozone upward. One end of the gas delivery pipe 53 is fixedly connected to the shunt pipe 51, and the other end of the gas delivery pipe 53 is fixedly penetrated through the top side of the tank body 1. Ozone enters from the end of the gas delivery pipe 53 located outside the tank body 1, and then the gas delivery pipe 53 delivers the ozone to the shunt pipe 51. The ozone inside the shunt pipe 51 is sprayed out from the aeration head 52, so that the sewage and the ozone are mixed and reacted.

[0045] Referring to Figure 2 The inside of the tank body 1 is sequentially installed with at least a filter screen 6, a support plate 7 and a catalyst layer 8 from bottom to top. The filter screen 6 is used to filter impurities in the sewage, so as to reduce the amount of impurities carried by the sewage when passing through the catalyst layer 8, and further reduce the occurrence of the bottom side of the catalyst layer 8 being blocked. The support plate 7 is used to support the catalyst layer 8. In the embodiment of the present application, the catalyst layer 8 is activated carbon overloading titanium dioxide.

[0046] Referring to Figure 2 , Figure 3 The bottom side of the support plate 7 is fixedly installed with a guide cover 9, and the guide cover 9 and the support plate 7 are both provided with a plurality of first through holes 10 for the sewage to pass through. The size of the first through hole 10 is smaller than the particle size of the catalyst layer 8, so as to facilitate the sewage to pass through the support plate 7, and the support plate 7 has a good supporting effect on the catalyst layer 8.

[0047] The drain pipe 12 sends the sewage from the space below the filter screen 6 of the tank body 1, and the aeration assembly 5 delivers ozone to the space below the filter screen 6 of the tank body 1. After the ozone and the sewage are mixed, they pass through the filter screen 6 and the support plate 7, and then the ozone and the sewage enter the inside of the catalyst layer 8. The catalyst layer 8 is beneficial to accelerate the reaction speed between the ozone and the sewage, and then the ozone and the sewage are discharged from the bottom side of the catalyst layer 8.

[0048] Referring to Figure 2 , Figure 3 The tank body 1 is provided with the drain pipe 12 on the top side of the tank body 1, and the tank body 1 is fixedly provided with the exhaust pipe 13 on the top side of the tank body 1. After the ozone and the sewage are discharged from the bottom side of the catalyst layer 8, the ozone and the air are discharged from the exhaust pipe 13, and the sewage reacts with the ozone to form treated water, which is discharged from the drain pipe 12.

[0049] Referring to Figure 3 , Figure 4 , Figure 5The top surface of the support plate 7 is fixedly provided with a guide pipe 14, and the guide pipe 14 is provided with a lifting rod 15. The support plate 7 is provided with a first lifting opening 16 for slidingly passing the lifting rod 15. The bottom end of the lifting rod 15 is fixedly provided with a limiting block 18. The lifting rod 15 slides in the first lifting opening 16, and when the lifting rod 15 rises, the limiting block 18 abuts against the bottom side of the support plate 7, so that the lifting rod 15 is not pulled out of the first lifting opening 16.

[0050] With reference to Figure 3 , Figure 4 The rod body of the lifting rod 15 is provided with a ring groove 19, and the ring groove 19 is internally provided with a mounting ring 20. The inner wall of the mounting ring 20 and the groove bottom of the ring groove 19 are fixedly provided with a connecting piece 21. The mounting ring 20 is fixedly provided in the ring groove 19 through the connecting piece 21.

[0051] With reference to Figure 4 , Figure 5 The mounting ring 20 is circumferentially provided with a plurality of pushing rods 22, and one end of the pushing rod 22 is provided with a mounting hole 23 for passing the mounting ring 20. The support plate 7 is provided with a plurality of second lifting openings 17 for passing the pushing rod 22, and the second lifting opening 17 is communicated with the first lifting opening 16. The inner side wall above the ring groove 19 is provided with a plurality of receiving grooves 24, and the pushing rod 22 is upwardly rotated and then enters the receiving groove 24, so as to conveniently keep the rod body of the lifting rod 15 flat.

[0052] With reference to Figure 3 , Figure 4 The inner side wall below the ring groove 19 is gradually lowered from the groove bottom to the groove opening and is obliquely arranged. When the pushing rod 22 is unfolded, the pushing rod 22 abuts against the inner side wall below the ring groove 19, and is affected by the oblique direction of the inner side wall below the ring groove 19, so that the one end of the pushing rod 22 close to the lifting rod 15 to the other end is gradually lowered and obliquely arranged, so as to conveniently drop the catalyst layer 8 from the pushing rod 22.

[0053] With reference to Figure 3 The pipe body of the guide pipe 14 is provided with a plurality of feeding openings 25. After the pushing rod 22 pushes the catalyst layer 8 in the guide pipe 14, the catalyst layer 8 outside the guide pipe 14 enters the guide pipe 14 from the feeding opening 25.

[0054] With reference to Figure 3The tank body 1 is provided with a lifting mechanism 26, which comprises a motor 261, a rotating rod 262, a winding disc 263 and a first pull rope 264. The body of the motor 261 is fixedly installed on the side wall of the tank body 1, and the rotating shaft of the motor 261 is fixedly penetrated through the side wall of the tank body 1. The rotating rod 262 is horizontally arranged inside the tank body 1, one end of the rotating rod 262 is rotatably inserted into the inner side wall of the tank body 1, and the other end of the rotating rod 262 is fixedly connected with the rotating shaft of the motor 261. The winding disc 263 is fixedly installed on the rotating rod 262, one end of the first pull rope 264 is fixedly connected with the winding disc 263, and the other end of the first pull rope 264 is fixedly connected with the top end of the lifting rod 15.

[0055] When the motor 261 is started, the motor 261 drives the winding disc 263 to wind or unwind the first pull rope 264 through the rotating rod 262. When the winding disc 263 winds the first pull rope 264, the lifting rod 15 rises; when the winding disc 263 unwinds the first pull rope 264, the lifting rod 15 descends under the action of gravity, thereby facilitating the lifting of the lifting rod 15.

[0056] Referring to Figure 3 The guide pipe 14 is fixedly sleeved with a plurality of first material guiding ring plates 3, the plurality of first material guiding ring plates 3 are spaced apart from each other at least from bottom to top, the circumferential side of the first material guiding ring plate 3 is enclosed with the inner side wall of the tank body 1 to form a first material falling port 27, the first material guiding ring plate 3 is gradually lowered from inside to outside and is arranged in an inclined manner, a second material guiding ring plate 4 is arranged between any two adjacent first material guiding ring plates 3, the circumferential side of the second material guiding ring plate 4 is fixedly connected with the inner side wall of the tank body 1, and the inner side wall of the second material guiding ring plate 4 and the pipe body of the guide pipe 14 are enclosed to form a second material falling port 28, and the second material guiding ring plate 4 is gradually lowered from outside to inside and is arranged in an inclined manner. The support plate 7 is gradually raised from the center of the position where the guide pipe 14 is located to all directions and is arranged in an inclined manner.

[0057] The catalyst layer 8 outside the guide pipe 14 is guided by the first material guiding ring plate 3, the second material guiding ring plate 4 and the support plate 7, thereby facilitating the movement of the part on the top side of the catalyst layer 8 to the bottom side of the catalyst layer 8, and the part on the bottom side of the catalyst layer 8 enters the inside of the guide pipe 14 from the material inlet 25.

[0058] Referring to Figure 3 The first material guiding ring plate 3 and the second material guiding ring plate 4 are both provided with a plurality of second through ports 11 for sewage to pass through. The second through port 11 is used for sewage and ozone to pass through, thereby reducing the occurrence of the situation that the ozone forms an air cavity below the first guide ring plate and the second material guiding ring plate 4.

[0059] Referring to Figure 2 , Figure 3The side of the tank body 1 is provided with two manholes 29, one manhole 29 is higher than the catalyst layer 8, and the other manhole 29 is lower than the filter screen 6. The manhole 29 is used for workers to enter the inside of the tank body 1 for cleaning. The side of the tank body 1 is also provided with a ladder 30, which is used for workers to move to the top side of the tank body 1.

[0060] The implementation principle of the decolorization reactor based on the ozone catalytic reaction in the embodiment of the application is as follows: the aeration assembly 5 sends ozone into the inside of the tank body 1, and the sewage enters the inside of the tank body 1 from the sewage pipe 2. Then the sewage and the ozone enter the catalyst layer 8 after passing through the filter screen 6 and the support plate 7, the catalyst layer 8 accelerates the reaction between the sewage and the ozone, so that the sewage forms treated water. Then the treated water is discharged from the drain pipe 12, and the ozone and the air are discharged from the exhaust pipe 13.

[0061] In the process that the ozone and the sewage pass through the catalyst layer 8, the driving mechanism drives the lifting rod 15 to repeatedly rise and fall. When the lifting rod 15 rises, the lifting rod 15 drives the pushing rod 22 to move upwards. The pushing rod 22 pushes the catalyst layer 8 in the inside of the guide pipe 14 out, and the catalyst layer 8 pushed out of the inside of the guide pipe 14 falls to the top side of the catalyst layer 8 outside the guide pipe 14. After the pushing rod 22 pushes the catalyst layer 8 in the inside of the guide pipe 14 out, the catalyst layer 8 outside the guide pipe 14 enters the inside of the guide pipe 14 from the feeding port 25. The part of the catalyst layer 8 at the bottom side moves to the top side of the catalyst layer 8, so that the situation that the bottom side of the catalyst layer 8 is blocked is reduced, and then the sewage and the ozone are facilitated to pass through the catalyst layer 8.

[0062] When the lifting rod 15 falls, the lifting rod 15 drives the pushing rod 22 to move downwards. The pushing rod 22 is blocked by the catalyst layer 8 in the inside of the guide pipe 14, and the pushing rod 22 rotates upwards and enters the inside of the storage groove 24, so that the situation that the pushing rod 22 presses the catalyst layer 8 is reduced. When the lifting rod 15 drives the pushing rod 22 to enter the guide cover 9, the lifting rod 15 rotates downwards under the action of gravity, so that the driving of the pushing rod 22 is facilitated to be unfolded.

[0063] Embodiment 2.

[0064] With reference to Figure 6 , Figure 7 , Figure 8 The decolorization reactor based on the ozone catalytic reaction in the embodiment of the application is different from the embodiment 1 in that the lifting mechanism 26 comprises a first floating block 265, a second pull rope 266 and a flow adjusting assembly 267, the first floating block 265 is located in the inside of the tank body 1 and above the catalyst layer 8. One end of the second pull rope 266 is fixedly connected with the first floating block 265, and the other end of the second pull rope 266 is fixedly connected with the top end of the lifting rod 15.

[0065] The flow adjusting assembly 267 comprises sliding rails 2671, a shielding plate 2672, a counterweight 2673, a second floating block 2674 and a magnetic block 2675. The sliding rails 2671 are fixedly installed on the inner side wall of the tank body 1, and the two sliding rails 2671 are located on both sides of the drain pipe 12. The shielding plate 2672 is slidably installed on the sliding rails 2671, and the shielding plate 2672 is used to shield one end of the drain pipe 12 located inside the tank body 1. The shielding plate 2672 is a hollow structure, the second floating block 2674 is fixedly installed on the top side of the shielding plate 2672, and the counterweight 2673 is fixedly installed on the side of the shielding plate 2672 away from the drain pipe 12. The magnetic block 2675 is fixedly installed on the inner top wall of the tank body 1, and the magnetic block 2675 is used to attract the second floating block 2674.

[0066] The implementation principle of the decolorization reactor based on the ozone catalytic reaction is that the shielding plate 2672 is driven by the counterweight 2673 to move downward, the shielding plate 2672 shields one end of the drain pipe 12 located inside the tank body 1, thereby reducing the amount of treated water discharged from the drain pipe 12. The amount of treated water discharged from the drain pipe 12 is reduced, thereby causing the water level of the sewage inside the tank body 1 to rise. When the water level of the sewage rises to immerse the second floating block 2674, the second floating block 2674 rises, and the magnetic block 2675 attracts the second floating block 2674. The shielding plate 2672 is driven by the buoyancy of the second floating block 2674 to rise, thereby opening one end of the drain pipe 12 located inside the tank body 1. After one end of the drain pipe 12 located inside the tank body 1 is opened, the water level of the sewage inside the tank body 1 drops, thereby causing the first floating block 265 to move downward, and the lifting rod 15 moves downward with the first floating block 265, thereby facilitating driving the lifting rod 15 to descend.

[0067] When the buoyancy provided by the sewage inside the tank body 1 is less than the gravity and the magnetic force of the magnetic block 2675 on the shielding plate 2672, the shielding plate 2672 shields the drain pipe 12 again after descending. The shielding plate 2672 is repeatedly raised and lowered, thereby facilitating driving the lifting rod 15 to ascend and descend.

[0068] When the buoyancy provided by the sewage inside the tank body 1 is less than the gravity and the magnetic force of the magnetic block 2675 on the shielding plate 2672, the shielding plate 2672 shields the drain pipe 12 again after descending. The shielding plate 2672 is repeatedly raised and lowered, thereby facilitating driving the lifting rod 15 to ascend and descend.

[0069] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
