[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides the following technical solution: an integrated sedimentation and filtration wastewater treatment device, comprising: The wastewater treatment cylinder assembly includes a base frame 101, which provides stable support, and a treatment cylinder 102 is fixedly connected to the top of the base frame 101, which treats wastewater. The flocculant addition assembly includes a flocculant inlet pipe 201 fixed to the top of the treatment cylinder 102, and a flocculant dispensing chamber 202 and a flocculant mixing chamber 203 located inside the treatment cylinder 102. The flocculant inlet pipe 201 is connected to the flocculant dispensing chamber 202. The flocculant inlet pipe 201 is connected to equipment according to the actual wastewater treatment situation, such as connecting to a pump with a flow meter. The pump dispenses flocculant at a precise flow rate, and the pumped flocculant enters through the flocculant inlet pipe 201. The flocculant is introduced into the flocculant dosing chamber 202, which is arranged vertically with the flocculant mixing chamber 203. Several flocculant adding pipes 204 are arranged at equal intervals along the axial direction inside the flocculant mixing chamber 203. The top ends of the several flocculant adding pipes 204 are fixed to the treatment cylinder 102 and communicate with the flocculant dosing chamber 202. The flocculant entering the flocculant dosing chamber 202 is diverted into the several flocculant adding pipes 204, and comes into contact with the wastewater after diversion, thereby improving the sedimentation effect. The diversion-type wastewater inlet assembly includes a wastewater inlet pipe 301 fixed to the top of the treatment cylinder 102, a wastewater inlet chamber 302 located inside the treatment cylinder 102 outside the flocculant inlet chamber 202, and several spiral wastewater mixing pipes 303 evenly spaced circumferentially inside the flocculant mixing chamber 203. The wastewater inlet pipe 301 is connected to the wastewater inlet chamber 302. The wastewater inlet pipe 301 is connected to equipment according to the actual wastewater treatment situation, such as connecting to a pump with a flow meter. The pump pumps in wastewater at a precise flow rate, and the pumped wastewater enters the wastewater inlet chamber 302 through the wastewater inlet pipe 301. The number of spiral wastewater mixing pipes 303 per turn is equal to the number of flocculant inlet chambers 202. The number of coagulant addition pipes 204 is the same. The top ends of several spiral wastewater mixing pipes 303 are fixed to the treatment cylinder 102 and connected to the wastewater inlet chamber 302. The wastewater entering the wastewater inlet chamber 302 is diverted into several spiral wastewater mixing pipes 303. The top sections of several spiral wastewater mixing pipes 303 are connected to the corresponding flocculant addition pipes 204. The wastewater diverted into several spiral wastewater mixing pipes 303 is mixed with the flocculant diverted into several flocculant addition pipes 204. The mixing is completed under the spiral collision of several spiral wastewater mixing pipes 303. The wastewater is divided into multiple streams for flocculant addition, which can improve the mixing effect of wastewater and flocculant. The openable sedimentation assembly includes a sedimentation and filtration integrated chamber 401 located inside the treatment cylinder 102 below the flocculant mixing chamber 203. Wastewater and flocculant mixed by the spiral collision of several spiral wastewater mixing pipes 303 enter the sedimentation and filtration integrated chamber 401 for static sedimentation. Two rotating shafts 402 are symmetrically rotatably connected inside the sedimentation and filtration integrated chamber 401. Two rotating sealing plates 403 are symmetrically fixedly sleeved on the outside of the two rotating shafts 402. The two rotating sealing plates 403 are parallel and closed during the static sedimentation of wastewater and flocculant, waiting for static sedimentation. After the static sedimentation is completed, the two rotating sealing plates 403 rotate downwards due to the rotation of the two rotating shafts 402, releasing the parallel and closed state. It also includes a rotation drive assembly. One end of the rotating shaft 402 extends through the processing cylinder 102 and outwards, with the through section and the other end connected to a bearing in the processing cylinder 102. The rotation drive assembly includes a mounting bracket 404 fixed to the top of the base frame 101 on one side of the processing cylinder 102, and two gears 408 fixedly sleeved on the two rotating shafts 402 extending outwards from the processing cylinder 102. A motor 405 is fixedly connected to the mounting bracket 404 away from the side wall of the processing cylinder 102. The motor 405 is the drive source, and the output end of the motor 405 and the rotating shaft 402 extending outwards from the processing cylinder 102 are respectively... A fixed pulley 406 is fitted onto two pulleys 406, and a transmission belt 407 is fitted onto the pulleys 406 for transmission connection. The motor 405 drives the pulley 406 to rotate, which in turn drives the other pulley 406 to rotate via the transmission belt 407. The other pulley 406 drives the connected rotating shaft 402 to rotate. Two gears 408 are meshed together, which in turn drives the connected gear 408 to rotate. The connected gear 408 drives the other meshed gear 408 to rotate, which in turn drives the other connected rotating shaft 402 to rotate, thus completing the opposite or opposite movement of the two rotating shafts 402.

[0020] The follow-up filter assembly includes a support rod 501 fixed to the bottom of the sedimentation filter integrated cavity 401. The support rod 501 provides a guide for movement. A filter plate 502 is movably sleeved on the support rod 501 through an external opening. The filter plate 502 abuts against the rotating sealing plate 403. In the flocculation and sedimentation state, the filter plate 502 abutting against the rotating sealing plate 403 cannot filter because the rotating sealing plate 403 is in a parallel and closed state. In the filtration state, the filter plate 502 is squeezed by the rotating and downward pressure of the rotating sealing plate 403, and there is a gap between the filter plate 502 and the rotating sealing plate 403, so that filtration can be performed. The support rod 501 is sleeved with a support spring 503, the two ends of which are fixed to the filter plate 502 and the bottom of the sedimentation filter integrated cavity 401, respectively. The support spring 503 provides support force for the filter plate 502 while allowing the filter plate 502 to move. The wastewater discharge assembly includes a wastewater outlet pipe 601 fixed to the side wall of the treatment cylinder 102 below the filter plate 502, through which the filtered wastewater is discharged. The impurity cleaning assembly includes a cleaning port 701 located on the side wall of the treatment cylinder 102 between the filter plate 502 and the wastewater outlet pipe 601, and an annular sealing plate 702 fixed to the bottom of the filter plate 502. The annular sealing plate 702 seals the cleaning port 701. The filter plate 502 has two states: one is the filtration state, in which the rotating sealing plate 403 rotates and presses the filter plate 502 down to the filtration position, and the filter plate 502 drives the annular sealing plate 702 to move down, sealing the cleaning port 701, allowing normal filtration; the other is the cleaning state, in which the rotating sealing plate 403 rotates and presses the filter plate 502 down to the cleaning position, and the filter plate 502 drives the annular sealing plate 702 to move down, making the filter plate 502 parallel to the cleaning port 701, and cleaning the impurities filtered on the filter plate 502 through the cleaning port 701.

[0021] Working principle of the invention: In the filtration state, flocculant enters the flocculant inlet chamber 202 through the flocculant inlet pipe 201. The flocculant in the flocculant inlet chamber 202 is then diverted into several flocculant addition pipes 204. Wastewater enters the wastewater inlet chamber 302 through the wastewater inlet pipe 301. The wastewater in the wastewater inlet chamber 302 is then diverted into several spiral wastewater mixing pipes 303. The wastewater diverted into the spiral wastewater mixing pipes 303 mixes with the flocculant diverted into the flocculant addition pipes 204, and the mixing is completed under the spiral collision of the spiral wastewater mixing pipes 303. The wastewater and flocculant mixed by the spiral collision of the spiral wastewater mixing pipes 303 then enter the sedimentation filtration integrated chamber 401 for static sedimentation. After static sedimentation, the... The machine 405 drives the connected pulley 406 to rotate, which in turn drives another pulley 406 to rotate via the transmission belt 407. The other pulley 406 drives the connected rotating shaft 402 to rotate, which in turn drives the connected gear 408 to rotate. The connected gear 408 drives another meshing gear 408 to rotate, which in turn drives the connected rotating shaft 402 to rotate. The two rotating shafts 402 moving in opposite directions drive the two rotating sealing plates 403 to move in opposite directions. During the movement of the two rotating sealing plates 403 in opposite directions, they press down on the filter plate 502. There is a gap between the two rotating sealing plates 403 and the filter plate 502. The settled wastewater is filtered through the filter plate 502 and discharged through the wastewater outlet pipe 601. In the cleaning state, the two rotating sealing plates 403 continue to press down on the filter plate 502 until the filter plate 502 is parallel to the cleaning port 701, and the impurities filtered on the filter plate 502 are cleaned through the cleaning port 701.
