Then the second electric push rod is started to push the isolation ring down to cover the opening, so that a sealed state is formed in the auxiliary pipe. Then the first electric push rod is started to drive the sleeve ring to rise. After the sleeve ring rises to the specified position, the second connecting pipe is inserted into the auxiliary pipe.

[0022] 4. Start the third electric push rod to drive the first scraper ring to slide and descend on the outer wall of the auxiliary pipe. While the first scraper ring descends, it drives the shovel ring installed on the bottom of the second scraper ring to scrape impurities on the outer wall of the auxiliary pipe. During the sewage separation process, the servo motor can be started to drive the auxiliary disk to rotate. While the auxiliary disk rotates, it drives the stirring rod to rotate in the wastewater, thereby increasing the activity of the sewage and making the solid-liquid separation of the sewage more complete. At the same time, the driving force of the water flow can be used to drive the water barrier to slide in the chute to expand the rotation range, thereby improving the auxiliary effect of sewage stirring.

The other end of each group of vacuum tubes 302 is connected to a group of water cylinders 306, and each group of water cylinders 306 is located directly below one of the second connecting tubes 206.

[0037] When only sticky mud is left after sewage treatment, the third electric push rod 406 is started to push the second scraper ring 409 down to the specified position, and then the second electric push rod 403 is started to drive the isolation ring 404 down to the specified position, and the opening 304 and the isolation gauze 410 are covered, and then the first electric push rod 209 is started to drive the sleeve ring 301 to squeeze the mud, and the vibration motor 210 is started to assist in vibration during the squeezing process, so that the isolation ring 404 is completely penetrated into the mud to squeeze out water, and at this time the second electric push rod 403 is started to drive the isolation ring 404 to rise slowly, and the squeezed water flow will enter the opening 304 through the isolation gauze 410, and the sludge will not enter the auxiliary pipe 303, thereby improving the sludge cleaning effect of sewage with the help of pressure, thereby improving the separation effect and the sludge cleaning effect of sewage treatment.

[0038] For example, Figure 5 and Figure 6 As shown, the mud cleaning component 4 includes a water-isolating ring 401, the inner wall of each group of the water-isolating rings 401 is sleeved on the outer wall of the auxiliary pipe 303, and a group of cavities 402 are opened on the bottom of each group of the water-isolating rings 401. A group of second electric push rods 403 are arranged in each group of the cavities 402, and a group of isolation rings 404 are installed on the output end of each group of the second electric push rods 403. A group of connecting rings 405 are installed on the inner wall of each group of the isolation rings 404, and the inner wall of each group of the connecting rings 405 is slidably connected to the auxiliary pipe 303. On the outer wall of the auxiliary tube 303, a group of third electric push rods 406 are installed on the bottom of each group of connecting rings 405, and a group of first scraper rings 407 are installed on the output end of each group of third electric push rods 406. The inner wall of each group of first scraper rings 407 is slidably connected to the outer wall of the auxiliary tube 303, and the outer wall is slidably connected to the inner wall of the isolation ring 404. Two groups of connecting blocks 408 are symmetrically installed on the bottom of each group of first scraper rings 407. A second scraper ring 409 is connected between the two groups of connecting blocks 408. The inner walls of the rings 409 are all slidably connected to the outer walls of the auxiliary tube 303, and the outer walls are all slidably connected to the inner walls of the isolation rings 404. Two groups of isolation gauze 410 are symmetrically connected between the two groups of connection blocks 408. A group of shovel rings 411 are installed on the bottom of each group of the second scraper rings 409. The output ends of each group of the shovel rings 411 are slidably connected to the outer walls of the auxiliary tube 303. Several groups of first fixed blocks 412 are distributed in a circular array on the outer walls of each group of the water-isolating rings 401. One side wall of each group of the first fixed blocks 412 is A group of fixed plates 413 are installed, and a group of sliding grooves 414 are opened on the bottom of each group of the first fixed plates 413. A group of water-blocking columns 415 are slidably connected in each group of the sliding grooves 414. A group of servo motors 416 are installed on the top inner wall of each group of the water-blocking columns 415. A group of auxiliary disks 417 are transmission-connected to the output end of each group of the servo motors 416. The top of each group of the auxiliary disks 417 is slidably fitted on the bottom of the water-blocking columns 415. A group of stirring rods 418 are installed on the bottom of each group of the auxiliary disks 417.

[0039] The third electric push rod 406 is started to drive the first scraper ring 407 to slide and descend on the outer wall of the auxiliary pipe 303. When the first scraper ring 407 descends, it drives the shovel ring 411 installed on the bottom of the second scraper ring 409 to scrape impurities from the outer wall of the auxiliary pipe 303, and drives two groups of isolation gauze 410 to wrap the opening 304 opened on the auxiliary pipe 303. Then, the first electric push rod 209 is started to push the sleeve ring 301 on the transmission rod 211 to descend, and the second electric ball valve 305 is opened. When the sleeve ring 301 descends, it drives several groups of auxiliary pipes 303 to penetrate into the wastewater. Then the wastewater begins to pass through the isolation gauze in sequence. 410 and the opening 304 into the auxiliary pipe 303, and the impurities are isolated by the isolating gauze 410, and then the second electric push rod 403 is started to push the isolating ring 404 down to cover the opening 304, so that a sealed state is formed in the auxiliary pipe 303, and then the first electric push rod 209 is started to drive the sleeve ring 301 to rise, and after the sleeve ring 301 rises to the specified position, the second connecting pipe 206 is allowed to penetrate into the auxiliary pipe 303, and then the water pump 208 is started to suck the wastewater filtered in the auxiliary pipe 303 into the separation pipe 203, and isolate it through the gauze partition 207, thereby improving the separation effect of sewage.

[0040] During the sewage separation process, the servo motor 416 can be started to drive the auxiliary disk 417 to rotate. While the auxiliary disk 417 rotates, it drives the stirring rod 418 to rotate in the wastewater, thereby increasing the activity of the sewage and making the solid-liquid separation of the sewage more complete. At the same time, the driving force of the water flow can be used to drive the water barrier 415 to slide in the chute 414 to expand the rotation range, thereby improving the auxiliary effect of sewage stirring.

[0041] For example, Figure 7 As shown, the shock absorbing assembly 5 includes a mounting plate 501, and a group of slideways 502 are provided on the top of each group of the mounting plates 501, and a group of mounting blocks 503 are installed on the inner walls of both sides of each group of the mounting plates 501, and a group of connecting rods 504 are installed on one side wall of each group of the mounting blocks 503. One end of a group of compression springs 505 is installed on one side wall of each group of the mounting blocks 503, and each group of the compression springs 505 is movably sleeved on the connecting rod 504, and a group of sliding rectangular plates 506 are installed on the other end of each group of the compression springs 505, and each group of the sliding rectangular plates 506 is movably sleeved on the connecting rod 504. A rectangular block 507 is connected between the two groups of the sliding rectangular plates 506, and the top of each group of the rectangular blocks 507 is installed on the bottom of the sewage tank 1.

[0042] The sealing cover 201 is opened to allow the sewage to enter the sewage tank 1, and then the sealing cover 201 is sealed with the sewage tank 1. In the subsequent working process, if deviation and shaking occur, the sewage tank 1 will drive the two sets of sliding rectangular plates 506 to slide in the slide. The two sets of sliding rectangular plates 506 begin to squeeze and pull one set of compression springs 505 respectively during the sliding process. When the compression spring 505 feels the pressure, it begins to rebound and repeatedly buffer until the structure is stable. In addition, it can also provide good buffering and protection for the sewage tank during subsequent transportation, thereby improving the stability of the device.

[0043] Start the second electric push rod 403 to drive the isolation ring 404 to descend to the specified position, and cover the opening 304 and the isolation gauze 410, and then drive the sleeve ring 301 to squeeze the soil. Vibration is assisted during the squeezing process so that the isolation ring 404 can penetrate completely into the soil to squeeze out water. At this time, start the second electric push rod 403 to drive the isolation ring 404 to rise slowly. At this time, the squeezed water flow will enter the opening 304 through the isolation gauze 410, and the sludge will not enter the auxiliary pipe 303. The pressure is used to improve the sludge cleaning effect of sewage, thereby improving the separation effect and the sludge cleaning effect of sewage treatment.

[0044] The sewage enters the sewage tank 1, so that the sealing cover 201 is sealed with the sewage tank 1. In the subsequent working process, if the displacement and shaking occur, the sewage tank 1 will drive the two sets of sliding rectangular plates 506 to slide in the slide. The two sets of sliding rectangular plates 506 begin to squeeze and pull one set of compression springs 505 respectively during the sliding process. When the compression spring 505 feels the pressure, it begins to rebound and repeatedly buffer until the structure is stable. In addition, it can also provide good buffering and protection for the sewage tank during the subsequent transportation, thereby improving the stability of the device.

[0045] The wastewater begins to pass through the isolation gauze 410 and the opening 304 in turn and enters the auxiliary pipe 303. The impurities are isolated by the isolation gauze 410. Then the second electric push rod 403 is started to push the isolation ring 404 down to cover the opening 304, so that a sealed state is formed in the auxiliary pipe 303. Then the first electric push rod 209 is started to drive the sleeve ring 301 to rise. After the sleeve ring 301 rises to the specified position, the second connecting pipe 206 is penetrated into the auxiliary pipe 303. Then the water pump 208 is started to suck the filtered wastewater in the auxiliary pipe 303 into the separation pipe 203, and isolate it through the gauze partition 207, thereby improving the separation effect of sewage.

[0046] Start the third electric push rod 406 to drive the first scraper ring 407 to slide and descend on the outer wall of the auxiliary pipe 303. While the first scraper ring 407 descends, it drives the second scraper ring 409 with a shovel ring 411 installed on the bottom to scrape impurities from the outer wall of the auxiliary pipe 303. During the sewage separation process, the servo motor 416 can be started to drive the auxiliary disk 417 to rotate. While the auxiliary disk 417 rotates, it drives the stirring rod 418 to rotate in the wastewater, thereby increasing the activity of the sewage and making the solid-liquid separation of the sewage more thorough. At the same time, the driving force of the water flow can be used to drive the water barrier 415 to slide in the slide 414 to expand the rotation range, thereby improving the auxiliary effect of sewage stirring.
