Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment equipment, and in particular to a supergravity wet oxidation reactor and sewage treatment equipment and method thereof. Background Art

[0002] The ultra-gravity wet oxidation reactor is a new type of sewage treatment equipment, which is mainly used to treat sewage containing difficult-to-degrade organic matter. The ultra-gravity wet oxidation reactor uses the ultra-gravity environment generated by the rotating device to increase the collision frequency of the reactants, thereby accelerating the reaction rate. The wet oxidation process degrades the organic matter in the sewage into water and carbon dioxide through oxidation reactions under high temperature and high pressure.

[0003] Among them, after the reactor removes harmful substances in the sewage, it is often necessary to treat the solid residues in the sewage. The common treatment method usually relies on filtering through a filter. However, as the filtration process proceeds, the filter will become clogged and the filtration rate may slow down, affecting the overall sewage treatment efficiency. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a supergravity wet oxidation reactor and sewage treatment equipment thereof, including a sewage discharge mechanism, the sewage discharge mechanism also includes a reactor and a sewage treatment tank, the top of the inner wall of the sewage treatment tank is fixedly connected with a fixing ring 1, the outer wall of the fixing ring 1 is fixedly connected with three connecting frames 1, and the parts contained in the three connecting frames 1 are the same;

[0006] The collecting mechanism comprises an oil pipe fixedly connected to the side wall of the fixed frame, hydraulic oil is arranged on the inner wall of the oil pipe, a piston rod is slidably connected to the inner wall of the oil pipe, and a spring piston rod is slidably connected to the inner wall of the oil pipe.

[0007] Preferably, the sewage discharge mechanism further comprises a drainage pipe connected through the bottom of the reactor, the outer wall of the sewage treatment tank is connected through the side wall of the drainage pipe, the top of the sewage treatment tank is fixedly connected with a motor, and the bottom output end of the motor is fixedly connected with a rotating rod;

[0008] Among them, a cylindrical screen is arranged on the inner wall of the sewage treatment tank, the bottom of the rotating rod is fixedly connected to the bottom of the inner wall of the cylindrical screen, and a drum is rotatably connected to the inner wall of the connecting frame. The staff injects sewage from the top water inlet of the reactor, and then starts the reactor to carry out oxidation reaction on the sewage. After the oxidation reaction is completed, the sewage is discharged into the sewage treatment tank through the drain pipe, so that the sewage enters the cylindrical screen, and then the motor is started to drive the rotating rod to rotate, so that the cylindrical screen rotates, and the sewage in the cylindrical screen rotates together, and the liquid in the sewage is thrown out to filter the sewage, so that the solid residue adheres to the inner wall of the cylindrical screen. The filtered liquid will enter the sewage treatment tank and be discharged through the drain port in the sewage treatment tank. When the cylindrical screen rotates, the drum will contact the inner wall of the cylindrical screen, and the drum will be affected by the friction of the inner wall of the cylindrical screen, so that it rotates itself. When the drum rotates, the impurities attached to the inner wall of the cylindrical screen will be adsorbed on the surface of the drum.

[0009] Preferably, the sewage discharge mechanism further comprises an arc-shaped ring fixedly connected to the bottom of the inner wall of the cylindrical screen, a sliding plate 1 is slidably connected to the inner wall of the connecting frame 1, a sliding rod is fixedly connected to the bottom of the sliding plate 1, the bottom of the sliding rod is slidably connected to the top of the arc-shaped ring, and five rollers 2 are rotatably connected to the inner wall of the sliding plate 1;

[0010] Among them, five cleaning brushes are fixedly connected to the inner wall of the sliding plate one, and a reset spring is fixedly connected to the top of the sliding plate one. At the same time, when the cylindrical screen rotates, it will drive the arc ring to rotate and contact the sliding rod. When the convex position of the arc ring contacts the sliding rod, the sliding rod will be lifted up, driving the sliding plate one to rise and squeeze the reset spring. As the arc ring continues to rotate, the sliding rod will return to its original position under the influence of the rebound force of the reset spring, driving the sliding plate one to return to its original position, so that the sliding plate one moves back and forth up and down. When the sliding plate one moves back and forth up and down, it will drive the drum two and the cleaning brush to move back and forth. As the cleaning brush moves, roller two will come into contact with the surface of roller one. Under the influence of the friction force of the outer wall of roller one, roller two can rotate, thereby rubbing the surface of roller one, and adsorbing impurities on the surface of roller one onto roller one. When roller two rotates, it will come into contact with the cleaning brush, thereby removing impurities on roller two, so that roller one is in a clean state for a long time, and can continuously remove impurities on the inner wall of the cylindrical screen, prevent impurities from accumulating on the inner wall of the cylindrical screen, avoid clogging of the cylindrical screen, and allow sewage to pass through the cylindrical screen smoothly, maintaining a good sewage treatment speed and efficiency.

[0012] The inner wall of the jet tube is rotatably connected with an air blocking plate, the side wall of the air blocking plate is fixedly connected with a spring rotating plate, and the bottom of the extrusion plate one is fixedly connected with a connecting block. The force of the moving rotating rod will cause the sliding frame to slide in the cam groove when the rotating rod rotates. As the rotating rod rotates, the sliding frame will reciprocate up and down. When the sliding frame descends, it will drive the extrusion plate one to descend and squeeze the gas in the fixed frame. The compressed gas will be blocked by the air blocking plate, causing the gas to generate high pressure. At the same time, when the sliding plate one rises, it will drive the jet tube and the extrusion plate two to rise, and the gas will be squeezed again. As the extrusion plate one and the extrusion plate two approach each other, the connecting block and the spring rotating plate will contact, pushing the spring rotating plate to rotate, driving the air blocking plate to rotate, and allowing the compressed gas to be sprayed to the cleaning brush through the jet tube.

[0013] Preferably, the jet mechanism further comprises three connection frames 2 fixedly connected to the inner wall of the sewage treatment tank, the three connection frames 2 contain the same parts, the inner wall of the connection frame 2 is slidably connected with an extrusion plate 3, the top of the extrusion plate 3 is fixedly connected to the bottom of the sliding frame, and the outer wall of the sliding frame is slidably connected to the inner wall of the sewage treatment tank;

[0014] Among them, a spring plate is slidably connected to the inner wall of the connecting frame 2, and five nozzles are connected through the inner wall of the connecting frame 2. Five connecting holes are opened inside the spring plate. At the same time, when the sliding frame descends, the extrusion plate 3 will be driven to descend to squeeze the gas in the connecting frame 2. At this time, since the connecting hole on the spring plate is not connected with the nozzle, the gas will generate high pressure in the connecting frame 2. When the extrusion plate 3 descends and contacts the spring plate, it will push the spring plate to move, so that the connecting hole is connected with the nozzle, so that the high-pressure gas is sprayed to the cylindrical screen through the nozzle, sprayed to the sieve holes of the cylindrical screen, and the impurities in the sieve holes are blown, so that the impurities are attached to the roller one, and the impurities on the cleaning brush are blown so that the impurities on the cleaning brush fall to the bottom of the sliding plate one, so as to prevent these impurities from re-contaminating the surface of the roller two and affecting the cleaning effect of the roller one; in addition: by backblowing the sieve holes of the cylindrical screen, the sieve holes are prevented from being blocked due to the accumulation of debris, so as to ensure that the sewage can pass smoothly, so that it can process the sewage faster and improve the overall processing capacity.

[0015] Preferably, the collecting mechanism further comprises a fixing ring 2 fixedly connected to the inner wall of the oil delivery pipe, the inner wall of the fixing ring 2 is slidably connected to the outer wall of the spring piston rod, a pushing block is slidably connected to the inner wall of the sliding plate 1, the side wall of the pushing block is slidably connected to the side wall of the spring piston rod through a slider, and a sliding groove is provided on the inner wall of the pushing block;

[0016] Among them, a sliding plate 2 is slidably connected to the inner wall of the sliding groove, five air blowing pipes are fixedly connected to the inner wall of the pushing block, the outer walls of the five air blowing pipes are slidably connected to the inner wall of the sliding plate 2, and the side wall of the sliding plate 2 is slidably connected to the inner wall of the connecting frame 1. The force of the descending extrusion plate 1 is utilized, and when the extrusion plate 1 descends, it will contact the piston rod. Since the contact surfaces of the extrusion plate 1 and the piston rod are both inclined surfaces, the extrusion plate 1 will smoothly squeeze the piston rod to move the piston rod. Since there is hydraulic oil inside the oil pipeline, when the piston rod moves, it will push the hydraulic oil to move, and the spring piston rod is pushed to move by the hydraulic oil, so that the spring piston rod accumulates rebound force. When the spring piston rod moves, it will push the pushing block to move, and push the impurities that fall on the bottom of the sliding plate 1.

[0017] Preferably, the collecting mechanism further comprises an annular groove formed at the bottom of the inner wall of the cylindrical screen, an angled plate is fixedly connected to the side wall of the sliding plate 1, a sewage pipe is fixedly connected to the inner wall of the connecting frame 1, and a blocking rod is fixedly connected to the bottom of the inner wall of the connecting frame 1;

[0018] Among them, the outer wall of the blocking rod is slidably connected to the inner wall of the annular groove, the inner wall of the blocking rod is slidably connected with a spring telescopic rod, the inner wall of the cylindrical screen is rotatably connected with seven liquid-blocking plates, and the bottoms of the seven liquid-blocking plates are fixedly connected with arc springs. At the same time, since the sliding plate 2 is in a stationary state, when the pushing block moves, the sliding plate 2 will squeeze the gas in the sliding groove, let the gas spray out through the blowing pipe, blow the impurities, accelerate the movement of the impurities, and make the impurities slide into the sewage pipe through the bevel plate, so as to prevent excessive accumulation of impurities at the bottom of the sliding plate 1, resulting in the possibility of the cleaning brush being attached to the accumulated impurities, indirectly affecting the cleaning effect of the drum 1, and ensuring that the drum 1 maintains good performance and stability during long-term operation.

[0019] Preferably, the collecting mechanism further comprises a connecting plate fixedly connected to the outer wall of the spring piston rod, five spring return rods are slidably connected to the inner wall of the sliding plate 1, and the inner walls of the five spring return rods are all provided with hollow grooves;

[0020] Among them, the inner walls of the five hollow grooves are slidably connected with moving rods, the outer walls of the five moving rods are slidably connected to the inner wall of the connecting plate, and the outer walls of the five moving rods are slidably connected to the inner wall of the connecting frame one through a slider two. The force of the spring piston rod moving will also drive the connecting plate to move when the spring piston rod moves. The connecting plate will contact the spring reset rod during the movement process, and then push the spring reset rod to move, squeeze the spring reset rod, and let the spring reset rod accumulate rebound force. When the spring reset rod moves, it will contact the cleaning brush. When the squeezing plate rises, the squeezing force on the piston rod will disappear, and the accumulated rebound force of the spring piston rod will be quickly released and returned to its original position.

[0021] The method of using the ultra-gravity wet oxidation reactor machine sewage treatment equipment includes the following steps:

[0022] S1: Start the motor to drive the rotating rod to rotate, so that the cylindrical screen rotates, and the sewage in the cylindrical screen rotates together, so that the liquid in the sewage is thrown out to filter the sewage, and the solid residue is attached to the inner wall of the cylindrical screen;

[0023] S2: When the drum screen rotates, the drum 1 will contact the inner wall of the drum screen. The drum 1 is affected by the friction of the inner wall of the drum screen and rotates itself. When the drum 1 rotates, the impurities attached to the inner wall of the drum screen will be adsorbed on the surface of the drum 1.

[0024] S3: When the cylindrical screen rotates, it will drive the arc ring to rotate and contact the sliding rod. When the raised position of the arc ring contacts the sliding rod, it will push up the sliding rod, drive the sliding plate to rise, and squeeze the reset spring.

[0025] The present invention has the following beneficial effects:

[0026] (1) When the present invention is used, the staff injects sewage from the top water injection port of the reactor, and then starts the reactor to carry out an oxidation reaction on the sewage. After the oxidation reaction is completed, the sewage is discharged into the sewage treatment tank through the drain pipe, so that the sewage enters the cylindrical screen, and then the motor is started to drive the rotating rod to rotate, so that the cylindrical screen rotates, and the sewage in the cylindrical screen rotates together, and the liquid in the sewage is thrown out to filter the sewage, so that the solid residue adheres to the inner wall of the cylindrical screen. The filtered liquid will enter the sewage treatment tank and be discharged through the drain port in the sewage treatment tank. When the cylindrical screen rotates, the drum will contact the inner wall of the cylindrical screen. The drum is affected by the friction force of the inner wall of the cylindrical screen, so that it rotates itself. When the drum rotates, the impurities attached to the inner wall of the cylindrical screen are adsorbed on the surface of the drum. At the same time, when the cylindrical screen rotates, it will drive the arc ring to rotate and contact the sliding rod. When the convex position of the arc ring and When the sliding rod contacts, it will push up the sliding rod, drive sliding plate one to rise, and squeeze the reset spring. As the arc ring continues to rotate, the sliding rod will return to its position under the influence of the rebound force of the reset spring, drive sliding plate one to return, and make sliding plate one reciprocate up and down. When sliding plate one reciprocates up and down, it will drive roller two and the cleaning brush to move. Roller two will contact the surface of roller one. Roller two is affected by the friction force of the outer wall of roller one and can rotate on itself, thereby rubbing the surface of roller one and adsorbing impurities on the surface of roller one on roller one. When roller two rotates, it will contact the cleaning brush, thereby removing impurities on roller two, so that roller one is in a clean state for a long time, and can continuously remove impurities on the inner wall of the cylindrical screen, prevent impurities from accumulating on the inner wall of the cylindrical screen, avoid clogging of the cylindrical screen, make sewage pass through the cylindrical screen smoothly, and maintain good sewage treatment speed and efficiency.

[0027] (2) The present invention utilizes the force of the rotating rod to move. When the rotating rod rotates, the sliding frame will also slide in the cam groove. As the rotating rod rotates, the sliding frame will move up and down. When the sliding frame descends, it will drive the extrusion plate 1 to descend to squeeze the gas in the fixed frame. The compressed gas will be blocked by the air blocking plate, causing the gas to generate high pressure. At the same time, when the sliding plate 1 rises, it will drive the jet pipe and the extrusion plate 2 to rise, and squeeze the gas again. As the extrusion plate 1 and the extrusion plate 2 approach each other, the connecting block and the spring rotating plate will contact, pushing the spring rotating plate to rotate, driving the air blocking plate to rotate, and allowing the compressed gas to be sprayed to the cleaning brush through the jet pipe. At the same time, when the sliding frame descends, it will also drive the extrusion plate 3 to descend, squeezing the gas in the connecting frame 2. At this time Since the connecting hole on the spring plate is not connected to the nozzle, the gas will generate high pressure in the connecting frame 2. When the extrusion plate 3 descends and contacts the spring plate, it will push the spring plate to move, so that the connecting hole is connected to the nozzle, so that the high-pressure gas is sprayed to the cylindrical screen through the nozzle, and sprayed to the sieve holes of the cylindrical screen, and the impurities in the sieve holes are blown, so that the impurities are attached to the roller 1, and the impurities on the cleaning brush are blown to the bottom of the sliding plate 1, so as to prevent these impurities from re-contaminating the surface of the roller 2 and affecting the cleaning effect of the roller 1; in addition: by backblowing the sieve holes of the cylindrical screen, the sieve holes are prevented from being blocked due to the accumulation of debris, ensuring that the sewage can pass smoothly, so that it can process the sewage faster and improve the overall processing capacity.

[0028] (3) The present invention utilizes the downward force of the extrusion plate 1. When the extrusion plate 1 descends, it will contact the piston rod. Since the contact surfaces of the extrusion plate 1 and the piston rod are both inclined surfaces, the extrusion plate 1 will smoothly squeeze the piston rod to move the piston rod. Since there is hydraulic oil inside the oil pipeline, when the piston rod moves, it will push the hydraulic oil to move. The hydraulic oil pushes the spring piston rod to move, allowing the spring piston rod to accumulate rebound force. When the spring piston rod moves, it will push the push block to move, pushing the impurities that have fallen on the bottom of the sliding plate 1. At the same time, since the sliding plate 2 is in a stationary state, when the push block moves, the sliding plate 2 will squeeze the gas in the sliding groove, allowing the gas to be ejected through the blowing pipe to blow the impurities, accelerate the movement of the impurities, and make the impurities slide into the sewage pipe through the bevel plate, thereby preventing the impurities at the bottom of the sliding plate 1 from accumulating too much, causing the cleaning brush to adhere to the accumulated impurities, indirectly affecting the cleaning effect of the roller 1, and ensuring that the roller 1 maintains good performance and stability during long-term operation.

[0029] (4) The present invention utilizes the force of the spring piston rod moving. When the spring piston rod moves, it also drives the connecting plate to move. During the movement of the connecting plate, it contacts the spring return rod, and then pushes the spring return rod to move, squeezing the spring return rod to allow the spring return rod to accumulate resilience. When the spring return rod moves, it contacts the cleaning brush. When the squeezing plate rises, the squeezing force on the piston rod disappears, and the resilience accumulated in the spring piston rod is quickly released and returned to its original position. When the spring piston rod returns to its original position, it drives the connecting plate to return to its original position, so that the resilience accumulated in the spring return rod is released. The spring return rod is allowed to shake back and forth, touching the cleaning brush to make the cleaning brush shake. At the same time, when the spring return rod is separated from the cleaning brush, the moving rod will squeeze the gas in the hollow groove and blow the cleaning brush again. Combined with the shaking of the cleaning brush, the cleaning effect is further enhanced, avoiding impurities dropped from the top cleaning brush and accumulating on the bottom cleaning brush. The blowing distance is far from the bottom cleaning brush, thereby preventing the bottom cleaning brush from accumulating too many impurities and affecting the cleaning effect of the bottom cleaning brush, ensuring that each cleaning brush is at the best cleaning effect.

[0055] Among them, a spring plate 212 is slidably connected to the inner wall of the connecting frame 210, and five nozzles 213 are connected to the inner wall of the connecting frame 210. Five connecting holes are opened inside the spring plate 212. At the same time, when the sliding frame 203 descends, it will also drive the extrusion plate 3 211 to descend, squeezing the gas in the connecting frame 210. At this time, since the connecting hole on the spring plate 212 is not connected to the nozzle 213, the gas will generate high pressure in the connecting frame 210. When the extrusion plate 3 211 descends and contacts the spring plate 212, it will push the spring plate 212 to move, so that the connecting hole is connected to the nozzle 213, so that the high pressure The pressurized gas is sprayed toward the cylindrical screen 108 through the nozzle 213, and toward the sieve holes of the cylindrical screen 108, and the impurities in the sieve holes are blown, so that the impurities are attached to the roller 109, and the impurities on the cleaning brush 114 are blown, so that the impurities on the cleaning brush 114 fall on the bottom of the sliding plate 111, so as to prevent these impurities from re-contaminating the surface of the roller 113 and affecting the cleaning effect of the roller 109; in addition: by backblowing the sieve holes of the cylindrical screen 108, the sieve holes are prevented from being blocked due to the accumulation of debris, so as to ensure that the sewage can pass smoothly, so that it can process the sewage faster and improve the overall processing capacity.

[0056] The collecting mechanism 3 further comprises a second fixing ring 304 fixedly connected to the inner wall of the oil delivery pipe 301, the inner wall of the second fixing ring 304 is slidably connected to the outer wall of the spring piston rod 303, a push block 305 is slidably connected to the inner wall of the sliding plate 111, the side wall of the push block 305 is slidably connected to the side wall of the spring piston rod 303 through a slider, and a sliding groove 306 is provided on the inner wall of the push block 305;

[0057] The inner wall of the sliding groove 306 is slidably connected with a sliding plate 2 307, the inner wall of the pushing block 305 is fixedly connected with five blowing pipes 308, the outer wall of the five blowing pipes 308 is slidably connected with the inner wall of the sliding plate 2 307, the side wall of the sliding plate 2 307 is slidably connected with the inner wall of the connecting frame 1 104, and the force of the extrusion plate 1 204 descending is utilized. When the extrusion plate 1 204 descends, it will contact with the piston rod 302. The contact surfaces of 02 are all inclined surfaces, so the extrusion plate 204 will smoothly squeeze the piston rod 302 to move the piston rod 302. Since there is hydraulic oil inside the oil pipe 301, when the piston rod 302 moves, it will push the hydraulic oil to move, and the hydraulic oil will push the spring piston rod 303 to move, allowing the spring piston rod 303 to accumulate rebound force. When the spring piston rod 303 moves, it will push the push block 305 to move, pushing the impurities that have fallen on the bottom of the sliding plate 111.

[0058] The collecting mechanism 3 also includes an annular groove 311 formed at the bottom of the inner wall of the cylindrical screen 108, an angled plate 309 is fixedly connected to the side wall of the sliding plate 111, a sewage pipe 310 is fixedly connected to the inner wall of the connecting frame 104, and a blocking rod 312 is fixedly connected to the bottom of the inner wall of the connecting frame 104;

[0059] Among them, the outer wall of the blocking rod 312 is slidably connected to the inner wall of the annular groove 311, and the inner wall of the blocking rod 312 is slidably connected with a spring telescopic rod 313, and the inner wall of the cylindrical screen 108 is rotatably connected with seven liquid blocking plates 314, and the bottoms of the seven liquid blocking plates 314 are fixedly connected with arc springs 315. At the same time, since the sliding plate 2 307 is in a stationary state, when the pushing block 305 moves, the sliding plate 2 307 will squeeze the gas in the sliding groove 306, allowing the gas to be ejected through the blowing pipe 308, blowing the impurities, accelerating the movement of the impurities, and making the impurities slide into the drain pipe 310 through the bevel plate 309, preventing excessive accumulation of impurities at the bottom of the sliding plate 111, resulting in the possibility of the cleaning brush 114 adhering to the accumulated impurities, indirectly affecting the cleaning effect of the drum 109, and ensuring that the drum 109 maintains good performance and stability during long-term operation.

[0060] The collecting mechanism 3 further includes a connecting plate 316 fixedly connected to the outer wall of the spring piston rod 303, and five spring return rods 317 are slidably connected to the inner wall of the sliding plate 111, and the inner walls of the five spring return rods 317 are all provided with hollow grooves 318;

[0061] Among them, the inner walls of the five hollow grooves 318 are slidably connected with moving rods 319, and the outer walls of the five moving rods 319 are slidably connected to the inner wall of the connecting plate 316. The outer walls of the five moving rods 319 are slidably connected to the inner wall of the connecting frame 104 through a slider 2. The force of the spring piston rod 303 moving will also drive the connecting plate 316 to move when the spring piston rod 303 moves. The connecting plate 316 will contact the spring return rod 317 during the movement process, and then push the spring return rod 317 to move, squeeze the spring return rod 317, and let the spring return rod 317 accumulate rebound force. When the spring return rod 317 moves, it will contact the cleaning brush 114. When the squeezing plate 204 rises, the squeezing force on the piston rod 302 will disappear, and the accumulated rebound force of the spring piston rod 303 will be quickly released and returned to its original position.

[0062] There is no limitation on the number of the above components, and relevant technicians in the field can freely set them according to actual needs, as long as the above components are installed at the connection positions of the corresponding components with equal spacing.

[0063] The method for using the ultra-gravity wet oxidation reactor and the sewage treatment equipment thereof comprises the following steps:

[0064] S1: Start the motor 106 to drive the rotating rod 107 to rotate, so that the cylindrical screen 108 rotates, and the sewage in the cylindrical screen 108 rotates together, so that the liquid in the sewage is thrown out to filter the sewage, and the solid residue is attached to the inner wall of the cylindrical screen 108;

[0065] S2: When the cylindrical screen 108 rotates, the drum 109 will contact the inner wall of the cylindrical screen 108. The drum 109 is affected by the friction of the inner wall of the cylindrical screen 108 and rotates itself. When the drum 109 rotates, the impurities attached to the inner wall of the cylindrical screen 108 are adsorbed on the surface of the drum 109.

[0066] S3: When the cylindrical screen 108 rotates, it will drive the arc ring 110 to rotate and contact the sliding rod 112. When the raised position of the arc ring 110 contacts the sliding rod 112, the sliding rod 112 will be lifted, driving the sliding plate 111 to rise and squeeze the reset spring 115.

[0067] A specific application of this embodiment is as follows: when the present invention is used, the staff injects sewage from the top water injection port of the reactor 101, and then starts the reactor 101 to perform an oxidation reaction on the sewage. After the oxidation reaction is completed, the sewage is discharged into the sewage treatment tank 102 through the drain pipe 105, so that the sewage enters the cylindrical screen 108, and then the motor 106 is started to drive the rotating rod 107 to rotate, so that the cylindrical screen 108 rotates, and the sewage in the cylindrical screen 108 rotates together, the liquid in the sewage is thrown out to filter the sewage, and the solid residue is attached to the inner wall of the cylindrical screen 108. The filtered liquid will enter the sewage treatment tank 102 and be discharged through the drain port in the sewage treatment tank 102. When the cylindrical screen 108 rotates, the drum 109 will contact the inner wall of the cylindrical screen 108. The drum 109 is affected by the friction of the inner wall of the cylindrical screen 108 and rotates itself. When the drum 109 rotates, the impurities attached to the inner wall of the cylindrical screen 108 are adsorbed on the surface of the drum 109. At the same time, when the cylindrical screen 108 rotates, it drives the arc ring 110 to rotate and contact the sliding rod 112. When the convex position of the arc ring 110 is When the sliding rod 112 contacts the sliding rod 112, the sliding rod 112 will be lifted up, driving the sliding plate 111 to rise, squeezing the reset spring 115. As the arc ring 110 continues to rotate, the sliding rod 112 will return to its original position under the influence of the rebound force of the reset spring 115, driving the sliding plate 111 to return to its original position, so that the sliding plate 111 moves back and forth up and down. When the sliding plate 111 moves back and forth up and down, it will drive the roller 2 113 and the cleaning brush 114 to move, and the roller 2 113 will contact the surface of the roller 109. The roller 2 113 is affected by the outer wall of the roller 109. Due to the influence of friction, the roller 109 can rotate by itself, thereby rubbing the surface of the roller 109, and the impurities on the surface of the roller 109 are adsorbed on the roller 109. When the roller 113 rotates by itself, it will contact the cleaning brush 114, so as to remove the impurities on the roller 113, so that the roller 109 is in a clean state for a long time, and the impurities on the inner wall of the cylindrical screen 108 can be continuously removed to prevent the accumulation of impurities on the inner wall of the cylindrical screen 108, avoid the clogging of the cylindrical screen 108, and make the sewage pass through the cylindrical screen 108 smoothly, so as to maintain a good sewage treatment speed and efficiency;

[0068] Secondly, when the rotating rod 107 rotates, the sliding frame 203 will also slide in the cam groove 202. As the rotating rod 107 rotates, the sliding frame 203 will reciprocate up and down. When the sliding frame 203 descends, it will drive the squeezing plate 1 204 to descend and squeeze the gas in the fixed frame 201. The compressed gas will be blocked by the air blocking plate 207, so that the gas generates high pressure. At the same time, when the sliding plate 111 rises, it will drive the jet pipe 206 and the squeezing plate 205 to rise, and squeeze the gas again. As the squeezing plate 1 204 and the squeezing plate 205 approach each other, the connecting block 208 and the spring rotating plate 209 will contact, pushing the spring rotating plate 209 to rotate, driving the air blocking plate 207 to rotate, and allowing the compressed gas to be ejected to the cleaning brush 114 through the jet pipe 206. At the same time, when the sliding frame 203 descends, it will also drive the squeezing plate 3 211 to descend, squeezing the gas in the connecting frame 210 At this time, since the connecting hole on the spring plate 212 is not connected to the nozzle 213, the gas will generate high pressure in the connecting frame 210. When the extrusion plate 3 211 descends and contacts the spring plate 212, it will push the spring plate 212 to move, so that the connecting hole is connected to the nozzle 213, so that the high-pressure gas is sprayed to the cylindrical screen 108 through the nozzle 213, and the sieve holes of the cylindrical screen 108 are sprayed, and the impurities in the sieve holes are blown, so that the impurities are attached to the roller 109, and the impurities on the cleaning brush 114 are blown to the bottom of the sliding plate 111, so as to prevent these impurities from re-contaminating the surface of the roller 2 113 and affecting the cleaning effect of the roller 109; in addition: by backblowing the sieve holes of the cylindrical screen 108, the sieve holes are prevented from being blocked due to the accumulation of debris, so as to ensure that the sewage can pass smoothly, so that it can process the sewage faster and improve the overall processing capacity;

[0069] Secondly, when the extrusion plate 204 descends, it will contact the piston rod 302. Since the contact surfaces of the extrusion plate 204 and the piston rod 302 are both inclined surfaces, the extrusion plate 204 will smoothly squeeze the piston rod 302 to move the piston rod 302. Since there is hydraulic oil inside the oil pipe 301, when the piston rod 302 moves, it will push the hydraulic oil to move, and the spring piston rod 303 will be pushed to move by the hydraulic oil, so that the spring piston rod 303 accumulates rebound force. When the spring piston rod 303 moves, it will push the push block 305 to move, and the At the same time, since the sliding plate 307 is in a stationary state, when the push block 305 moves, the sliding plate 307 will squeeze the gas in the sliding groove 306, so that the gas is ejected through the blowing pipe 308 to blow the impurities, accelerate the movement of the impurities, and make the impurities slide into the sewage pipe 310 through the bevel plate 309, so as to prevent the impurities at the bottom of the sliding plate 111 from accumulating too much, causing the cleaning brush 114 to be attached to the accumulated impurities, indirectly affecting the cleaning effect of the roller 109, and ensuring that the roller 109 maintains good performance and stability during long-term operation;

[0070] Among them, since the sewage is quickly thrown out when it is just discharged into the cylindrical screen 108, the sewage content in the cylindrical screen 108 is relatively small, and the impurities discharged into the sewage inlet and outlet pipe 310 will fall into the annular groove 311. When the cylindrical screen 108 rotates, the impurities will be blocked by the blocking rod 312. When the cylindrical screen 108 rotates, the liquid blocking plate 314 will move to the bottom of the blocking rod 312. Since the spring telescopic rod 313 is in a compressed state, when the liquid blocking plate 314 moves to the bottom of the blocking rod 312, the resilience of the spring telescopic rod 313 will be released, pushing the liquid blocking plate 314 to rotate and squeezing the arc spring 315. When the liquid blocking plate 314 rotates, the impurities blocked by the blocking rod 312 will be discharged from the cylindrical screen 108, avoiding the collected impurities from being thrown onto the inner wall of the cylindrical screen 108 again.

[0071] Secondly, when the spring piston rod 303 moves, it will also drive the connecting plate 316 to move. During the movement of the connecting plate 316, it will contact the spring return rod 317, and then push the spring return rod 317 to move, squeeze the spring return rod 317, so that the spring return rod 317 accumulates resilience. When the spring return rod 317 moves, it will contact the cleaning brush 114. When the squeezing plate 204 rises, the squeezing force on the piston rod 302 will disappear, and the resilience accumulated in the spring piston rod 303 will be quickly released and returned to its original position. When the spring piston rod 303 returns to its original position, it will drive the connecting plate 316 to return to its original position, so that the resilience accumulated in the spring return rod 317 is released, and the spring return rod 3 17 shakes back and forth, touches the cleaning brush 114 to make the cleaning brush 114 shake. At the same time, when the spring return rod 317 is separated from the cleaning brush 114, the moving rod 319 will squeeze the gas in the hollow groove 318 to blow the cleaning brush 114 again. In conjunction with the shaking of the cleaning brush 114, the cleaning effect is further enhanced, and impurities dropped from the top cleaning brush 114 are prevented from accumulating on the cleaning brush 114 at the bottom. The blowing distance is far from the bottom cleaning brush 114, thereby preventing the bottom cleaning brush 114 from accumulating too many impurities and affecting the cleaning effect of the bottom cleaning brush 114, thereby ensuring that each cleaning brush 114 is in the best cleaning effect.
