Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Embodiment 1: This embodiment is used to solve the problem of traditional sewage treatment devices. Although the filter residues can be cleaned and centrally processed, some debris is still easy to clog the filter cartridge during the filtering process, affecting the subsequent filtering effect. It is difficult to quickly process the clogged debris and difficult to quickly discharge the debris, which can easily affect the filtering effect and reduce work efficiency.

[0018] See also Figure 1-Figure 7 As shown, this embodiment is a wastewater treatment device with a backwash cleaning effect, comprising a base 1, two symmetrically arranged support frames 2 are fixedly connected to the upper surface of the base 1, a collection barrel 4 is rotatably connected between the two support frames 2, and a filtering mechanism is arranged in the collection barrel 4; The filtering mechanism includes a filter cartridge 9 that penetrates the collection barrel 4 and is connected to the collection barrel 4 by fixed axis rotation.

The connection port 10 is connected to an external delivery end through a rotating joint to deliver sewage to the filter cartridge 9 for filtering treatment. A cleaning mechanism is provided on the collection barrel 4. The cleaning mechanism includes two symmetrically arranged guide rails 5 fixedly connected to the inner wall of the collection barrel 4 along the axial direction of the filter barrel 9, and a tooth plate 6 is slidably connected to each of the two guide rails 5. The guide rail 5 passes through the tooth plate 6 and is limitedly slidably connected to the tooth plate 6. A gear 7 is meshed between the two tooth plates 6. When one of the tooth plates 6 reciprocates on the guide rail 5, the gear 7 meshed with it can be reciprocated and deflected, and the other tooth plate 6 meshed with the gear 7 moves in the opposite direction. The lower surface of the tooth plate 1 6 is fixedly connected with a spaced connection seat 35, the connection seat 35 is rotatably connected with a movable frame 36, the movable frame 36 is fixedly mounted with a nozzle 37, the movable frame 36 is penetrated and axially slidably connected with a spline shaft 27, the spline shaft 27 penetrates the collection barrel 4 and is fixedly connected with a gear 3 26, when the gear 3 26 rotates, the movable frame 36 that is limitedly slidable with the spline shaft 27 can be deflected, thereby deflecting the nozzle 37 on the movable frame 36; When the nozzle 37 deflects back and forth, it cooperates with the rotation of the filter cartridge 9 to fully reversely flush the outer contour of the filter cartridge 9. By setting a cleaning mechanism, the nozzle 37 moves back and forth and swings at the same time, thereby expanding the flushing range of the filter cartridge 9, and can flush and clean the debris attached to the inner wall of the filter cartridge 9 to prevent the debris from clogging the filter holes on the filter cartridge 9. When one end of the filter cartridge 9 is tilted, the nozzle 37 at the bottom of the tooth plate 6 moves and flushes along the outer wall of the filter cartridge 9, so that the debris is discharged from one end of the filter cartridge 9. The cleaning mechanism and the filtering mechanism cooperate to continuously treat the sewage, reduce the maintenance time of the filter cartridge 9, and improve work efficiency.

[0019] A mounting frame 16 is fixedly connected to the upper surface of the collecting barrel 4, and a motor 2 17 is fixedly installed on the upper surface of the mounting frame 16. The output shaft of the motor 2 17 passes through the mounting frame 16 and is fixedly connected to a connecting strip 19. The motor 2 17 located on the mounting frame 16 is started, and the motor 2 17 drives the connecting strip 19 connected to its output shaft to rotate. A mounting frame 2 18 is fixedly connected to the upper surface of the tooth plate 6, and a movable groove 20 is provided on the surface of the mounting frame 2 18. The lower surface of the connecting strip 19 away from one end of the output shaft of the motor 2 17 is fixedly connected to a sliding column slidably connected to the movable groove 20. The sliding column on the lower surface of the connecting strip 19 moves in the movable groove 20 on the mounting frame 2 18, and can push the mounting frame 2 18 to move back and forth, thereby realizing the staggered reciprocating movement of the corresponding two tooth plates 6, and the outer wall of the filter cartridge 9 is fully flushed through the corresponding nozzle 37, and the outer wall of the filter cartridge 9 can be effectively and fully flushed along the outer wall of the filter cartridge 9.

[0020] The inner wall of the collecting barrel 4 is fixedly connected with a mounting plate 21, and the outer wall of the collecting barrel 4 is fixedly connected with a horizontally arranged limit bar. The limit bar on the collecting barrel 4 penetrates the tooth plate 25 and is horizontally slidably connected to the tooth plate 25. The limit bar on the collecting barrel 4 limits the tooth plate 25 so that the tooth plate 25 is limited in the horizontal direction. The tooth plate 25 is meshed with two gears 3 26. The upper surface of the mounting plate 21 is fixedly connected with a limit block 22, and the limit block 22 is penetrated and limitedly slidably connected with a T-shaped bar 23. The limit block 22 limits the T-shaped bar 23 so that it can be limited and moved along the direction of the mounting plate 21. One end of the T-shaped bar 23 close to the gear 3 26 is movably connected with a movable rod 24, and one end of the movable rod 24 away from the T-shaped bar 23 is movably connected to the tooth plate 25, and the movable rod 24 is movably connected to the T-shaped bar 23 and the tooth plate 25 through a rotating shaft. When the T-bar 23 moves along the surface of the mounting plate 21, it can push the movable rod 24 movably connected thereto, so that the movable rod 24 pushes the tooth plate 25 to move. The movement of the tooth plate 25 can cause the two gears 3 26 meshing therewith to rotate, thereby controlling the spline shaft 27 coaxially fixed with the gear 3 26 to rotate. The rotation of the spline shaft 27 drives the movable frame 36 and the nozzle 37 to swing, which can expand the spraying range. At the same time, the swinging flushing method is beneficial to removing foreign particles on the filter cartridge 9.

[0021] The gear 17 is located on the mounting plate 21 and is connected to the mounting plate 21 for fixed-axis rotation. The upper surface of the gear 17 is fixedly connected to the mounting frame 21. The end of the T-bar 23 near the gear 17 is provided with a sliding groove that is slidably connected to the eccentric column 8. The mounting frame 218 is L-shaped, and a certain gap is set between the T-bar 23 and the mounting frame 218 to prevent interference between the mounting frame 218 and the T-bar 23. When the tooth plate 16 moves back and forth and causes the gear 17 meshing with the tooth plate 16 to deflect, the eccentric column 8 located on the gear 17 reciprocates to push the T-bar 23 to move, thereby causing the above-mentioned movable frame 36 to reciprocate, which can fully clean the outer wall of the filter cartridge 9. Compared with the use of an electric push rod for reciprocating pushing, there is no need to add additional electrical components and corresponding control systems, and the kinetic energy of the motor 17 can be fully utilized.

[0022] One end of the collecting barrel 4 near the connecting port 10 is fixedly connected with a mounting seat 13, and a motor 14 is fixedly installed on the upper surface of the mounting seat 13. The output end of the motor 14 is fixedly connected with a gear 2 11, and the outer contour of the filter cartridge 9 near the connecting port 10 is fixedly connected with a gear ring 12 meshing with the gear 2 11. The motor 14 located on the mounting seat 13 is started, and the motor 14 drives the gear 2 11 to rotate, thereby driving the large gear through the small gear, or driving the reduction motor, so that the filter cartridge 9 can rotate slowly, so that the filter cartridge 9 can rotate on its own and cooperate with the nozzle 37 on the movable frame 36 to fully reverse flush the outer wall of the filter cartridge 9 to prevent the filter cartridge 9 from being blocked and affecting the filtering effect of the filter cartridge 9.

[0023] Embodiment 2: This embodiment is used to solve the problem of preventing debris from clogging the filter cartridge, reducing the impact on subsequent filtering effects, while not affecting the rapid discharge of debris.

[0025] The end of the collecting barrel 4 away from the gear three 26 is fixedly connected to the mounting frame three 31, and the upper surface of the mounting frame three 31 is fixedly connected to the hydraulic rod two 28, and the telescopic end of the hydraulic rod two 28 is fixedly connected to the connecting frame 30, and the end of the connecting frame 30 away from the hydraulic rod two 28 is fixedly connected to the sleeve 29, and the end of the sleeve 29 is fixedly connected to the sealing plug 32 adapted to the end opening of the filter cartridge 9. One side of the mounting frame three 31 is fixedly connected to a limiting rod 39 that penetrates the connecting frame 30 and is slidably connected to the connecting frame 30. The hydraulic rod two 28 located on the mounting frame three 31 is started, and the telescopic end of the hydraulic rod two 28 pushes the connecting frame 30, so that the sleeve 29 fixedly connected to the connecting frame 30 pushes the sealing plug 32 to move. The sealing plug 32 is truncated cone-shaped, and the sealing plug 32 moves into the filter cartridge 9 and separates from the end of the filter cartridge 9, so that the end of the filter cartridge 9 close to the collection box 3 is opened, so that the debris in the filter cartridge 9 is discharged.

[0026] The sleeve 29 is penetrated by and rotatably connected with a connecting shaft 33, which extends into the filter cartridge 9, and the outer wall of the connecting shaft 33 is fixedly connected with a fixing frame 34, and the end of the fixing frame 34 is fixedly connected with a scraper 38, and the scraper 38 abuts against the inner wall of the filter cartridge 9. Motor three is fixedly installed on the connecting frame 30, and the motor three drives the connecting shaft 33 fixedly connected thereto to rotate. The connecting shaft 33 rotates to scrape off the debris on the inner wall of the filter cartridge 9, thereby further facilitating the discharge of the filtered debris from the end of the filter cartridge 9 close to the collection box 3.

[0027] An electric push rod is fixedly installed on one side of the collection barrel 4, and the telescopic end of the electric push rod passes through the tooth plate 25 for fixed connection. The T-bar 23, the eccentric column 8 and the movable rod 24 are replaced by the electric push rod, and the tooth plate 25 is pushed by the electric push rod, so that the two gears 3 26 meshing with the tooth plate 25 rotate, so that the corresponding nozzle 37 can rotate, further expanding the spraying range.

[0028] In combination with Example 1 and Example 2, it can be known that the present invention is to set a cleaning mechanism to achieve reciprocating movement and swinging of the nozzle 37 on the outer contour of the filter cartridge 9, which can expand the flushing range and cooperate with the filter cartridge 9 to rotate itself, so as to comprehensively and effectively reversely flush the filter cartridge 9, effectively remove debris attached to the filter cartridge 9, prevent filter hole clogging, and maintain filtering efficiency. At the same time, the coordinated work of the cleaning mechanism and the filtering mechanism can continuously treat sewage, reduce downtime caused by maintenance, and achieve continuous operation of wastewater treatment, which helps to improve overall work efficiency and production capacity. By lifting the filter cartridge 9 and further cooperating with the cleaning mechanism, the nozzle 37 reciprocates along the direction of the filter cartridge 9, so that the debris in the filter cartridge 9 can be flushed to the lower side, which is convenient for the debris in the filter cartridge 9 to be discharged through the opening at its end. It has the advantages of fast cleaning speed, good effect and simple maintenance, and is a wastewater treatment equipment with broad application prospects.

[0029] like Figure 1-Figure 7 As shown, the working process and principle of the present invention are as follows: Step 1: Connect the external sewage to the connection port 10 at the end of the filter cartridge 9 through a rotary joint. After the filter cartridge 9 filters the sewage, when the filter cartridge 9 needs to be cleaned, start the motor 2 17 located on the collection barrel 4. The motor 2 17 drives the connecting bar 19 connected to its output shaft. The sliding column on the lower surface of the connecting bar 19 moves in the movable groove 20 on the mounting frame 2 18, which can push the mounting frame 2 18 to move back and forth. The toothed plate 16 fixedly connected to the mounting frame 18 moves, and the gear 17 deflects back and forth at this time, and the eccentric column 8 moves in the slide groove on the T-bar 23. The eccentric column 8 pushes the T-bar 23 to move. When the T-bar 23 moves along the surface of the mounting plate 21, it can push the movable rod 24 movably connected thereto, so that the movable rod 24 pushes the toothed plate 25 to move. The movement of the toothed plate 25 can make the two gears 3 26 meshing therewith rotate, thereby realizing the control of the spline shaft 27 coaxially fixed with the gear 3 26 to rotate.
