[0035] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to specific embodiments.

[0036] Example 1, given by Figure 1 , Figure 2 , Figure 3 and Figure 5 , the present invention includes a multi-stage treatment tank 1. A chemical addition pipe 2 is fixedly connected to the outer wall of the multi-stage treatment tank 1. A chemical stirring structure is provided in the multi-stage treatment tank 1 below the chemical addition pipe 2.

A secondary filtration mechanism is installed in the multi-stage treatment tank 1 below the filter cartridge 8;

[0038] The wastewater to be treated enters the filter cartridge 8 through the inlet unit. The filter cartridge 8 filters the fibrous fabrics in the wastewater. The wastewater after the first filtration is filtered by the secondary filtration mechanism to remove large particles of impurities. The wastewater after the secondary filtration flows to the lower half of the multi-stage treatment tank 1. A flocculant is added to the multi-stage treatment tank 1 through the chemical addition pipe 2. The wastewater and the flocculant in the multi-stage treatment tank 1 are stirred by the chemical stirring structure to fully mix the wastewater and the flocculant, improving the wastewater purification effect. When the wastewater purification is completed, the valve on the water outlet pipe 4 is opened to discharge the purified wastewater. When it is necessary to discharge the waste settled in the multi-stage treatment tank 1, the valve on the impurity discharge pipe 56 is opened to discharge the waste settled in the multi-stage treatment tank 1. The driving assembly drives the rotating disk 21 and the filter cartridge 8 to rotate, changing the position of the filter cartridge 8 below the rotating pipe 7, and filtering the wastewater through different positions on the filter cartridge 8. When it is necessary to clean the filter cartridge 8, the driving assembly drives the filter cartridge 8 to rotate to the cleaning station, and the cleaning and collection structure cleans the filter cartridge 8 at the cleaning station. The cleaned impurities fall onto the cleaning hopper 11, and the cleaned impurities are discharged through the cleaning hopper 11. It is not necessary to remove the filter cartridge 8 from the multi-stage treatment tank 1 to clean the filter cartridge 8, which improves the convenience and reduces the impact of disassembling and assembling the filter cartridge 8 on the wastewater treatment efficiency.

[0039] Embodiment 2, on the basis of Embodiment 1, by Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7Given that the water inlet unit includes a water inlet pipe 6 fixedly installed on the outer wall of the multi-stage treatment tank 1. A rotating pipe 7 located inside the multi-stage treatment tank 1 is rotatably sleeved outside the water inlet pipe 6. The rotating pipe 7 penetrates through two rotating disks 21 respectively, and a number of water inlet heads 9 located inside the filter cylinder 8 are fixedly installed on the rotating pipe 7. The driving assembly includes a support pipe 22 fixedly installed on the side of the rotating disk 21 away from the filter cylinder 8. A rotating seat 5 located above the chemical addition pipe 2 is rotatably connected inside the multi-stage treatment tank 1, and the support pipe 22 and the rotating seat 5 are rotatably connected. The inner wall of the support pipe 22 is in contact with the outer wall of the rotating pipe 7. A first bevel gear 23 is fixedly installed on the support pipe 22, and the rotating pipe 7 penetrates through the first bevel gear 23. A first rotating shaft 24 is rotatably connected to the rotating seat 5, and a second bevel gear 25 meshing with the two first bevel gears 23 is fixedly installed on the first rotating shaft 24. A second servo motor 26 is fixedly connected to the outer wall of the multi-stage treatment tank 1, and the output end of the second servo motor 26 is fixedly connected to the first rotating shaft 24. The multi-stage treatment tank 1 is equipped with a rotating unit for driving the rotating seat 5 to rotate. The rotating unit includes a third servo motor 27 fixedly installed on the outer wall of the multi-stage treatment tank 1. The output end of the third servo motor 27 is fixedly connected to a first sprocket 28 located inside the multi-stage treatment tank 1. A second sprocket 29 is fixedly connected to the rotating seat 5, and the first sprocket 28 and the second sprocket 29 are driven by a first chain 30;

[0040] The wastewater to be cleaned enters the rotating pipe 7 through the water inlet pipe 6, and the wastewater is discharged into the filter cylinder 8 through the water inlet heads 9 on the rotating pipe 7. By driving the first rotating shaft 24 to rotate through the second servo motor 26, the first rotating shaft 24 can drive the support pipe 22 and the rotating disk 21 to rotate through the second bevel gear 25 and the first bevel gear 23, and the rotating disk 21 can drive the filter cylinder 8 to rotate self. By driving the first sprocket 28 to rotate through the third servo motor 27, the first sprocket 28 drives the second sprocket 29 and the rotating seat 5 to rotate relative to the multi-stage treatment tank 1 through the first chain 30, and the multi-stage treatment tank 1 can drive the support pipe 22, the rotating disk 21 and the filter cylinder 8 to revolve, so that the filter cylinder 8 rotates to the cleaning station, and the filter cylinder 8 can be cleaned through the cleaning and collection structure.

[0041] Embodiment 3, on the basis of Embodiment 2, by Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 11Given that the cleaning and collection structure includes a waste discharging hopper 31 fixedly installed at one end of the filter cartridge 8 away from the rotating disk 21. One side of the waste discharging hopper 31 away from the filter cartridge 8 is in contact with a sealing plate 36, and the sealing plate 36 is rotatably connected to the rotating seat 5. The multi-stage treatment tank 1 is equipped with an opening and closing member adapted to the sealing plate 36. A swing pipe 57 is provided in the multi-stage treatment tank 1. A flushing pipe 44 is fixedly connected to the outer wall of the multi-stage treatment tank 1. The bottom end of the swing pipe 57 and the flushing pipe 44 are connected by a hose 45. A number of spray heads 46 are fixedly connected to the swing pipe 57. The multi-stage treatment tank 1 is equipped with an inclinator for driving the swing pipe 57 to tilt. An installation strip 33 is provided in the filter cartridge 8. A scraping plate 20 in contact with the inner wall of the filter cartridge 8 is fixedly connected to the installation strip 33. The installation strip 33 penetrates through the waste discharging hopper 31, and the installation strip 33 and the rotating seat 5 are fixedly connected by a fixing frame 32. A notch adapted to the installation strip 33 is formed on the sealing plate 36. The opening and closing member includes an arc-shaped slide rail 39 fixedly installed in the multi-stage treatment tank 1. A hydraulic telescopic rod 42 is fixedly installed on the multi-stage treatment tank 1, and the telescopic end of the hydraulic telescopic rod 42 is fixedly connected with a movable block 40 adapted to the notch of the arc-shaped slide rail 39. Stopping plates 37 respectively penetrate through both ends of the rotating seat 5. One side of the sealing plate 36 away from the filter cartridge 8 is in contact with the sealing plate 36. A slider 38 is fixedly installed on the stopping plate 37. Sliding grooves 41 adapted to the slider 38 are formed on both the arc-shaped slide rail 39 and the movable block 40, and the slider 38 is located in the sliding groove 41 on the arc-shaped slide rail 39. The inclinator includes second rotating shafts 43 respectively fixedly installed on both sides of the swing pipe 57. The second rotating shafts 43 are rotatably connected to the multi-stage treatment tank 1. The swing pipe 57 is fixedly installed with a second supporting part 49. The second supporting part 49 and the inner wall of the multi-stage treatment tank 1 are connected by a tension spring 50. A first supporting part 47 is fixedly connected to the swing pipe 57. A number of bumps 48 adapted to the first supporting part 47 are fixedly connected to the outer wall of the rotating disk 21. A guiding ring 34 is fixedly connected to the side of the rotating disk 21 facing the filter cartridge 8. A guiding groove 35 adapted to the guiding ring 34 is formed at one end of the installation strip 33 away from the fixing frame 32;

[0042] When the filter cartridge 8 rotates around its own axis relative to the rotating base 5, the scraper 20 and the mounting strip 33 are fixed relative to the rotating base 5. At this time, the scraper 20 cleans the inner wall of the filter cartridge 8, and the fiber fabric on the filter cartridge 8 after being cleaned stays on the top of the scraper 20, preventing the fiber fabric from blocking the filter cartridge 8 and improving the wastewater treatment speed and quality. When it is necessary to remove the fiber fabric in the filter cartridge 8, the rotating base 5 is driven to rotate by the driving assembly. The filter cartridge 8 rotates around the water inlet pipe 6 as the axis, and the rotating pipe 7 rotates relative to the water inlet pipe 6. The sealing plate 36 seals the impurity discharge hopper 31 to prevent the fiber fabric in the filter cartridge 8 from falling out through the impurity discharge hopper 31. The rotating base 5 drives the slider 38 to slide in the chute 41 on the arc-shaped slide rail 39 through the stop plate 37. When the filter cartridge 8 rotates to the cleaning station, the slider 38 slides from the chute 41 on the arc-shaped slide rail 39 to the chute 41 on the movable block 40. The movable block 40 is driven to move by the hydraulic expansion rod 42, and the movable block 40 drives the slider 38 and the stop plate 37 to translate, so that the stop plate 37 no longer supports the sealing plate 36. The sealing plate 36 rotates relative to the rotating base 5 due to gravity, so that the impurity discharge hopper 31 at the cleaning station is in an open state. At this time, the rotating disk 21 moves to one side of the first support portion 47, and the first support portion 47 contacts the rotating disk 21. The tension spring 50 is in a stretched state, and the tension spring 50 applies a pulling force to the second support portion 49 and the swing pipe 57, so that the first support portion 47 abuts against the rotating disk 21. The flushing pipe 44 is connected to the external flushing liquid through a water pump. The water pump pumps the flushing liquid into the swing pipe 57 through the flushing pipe 44 and the hose 45. The flushing liquid in the swing pipe 57 is sprayed onto the filter cartridge 8 through the nozzle 46. The driving assembly drives the rotating disk 21 and the filter cartridge 8 to rotate around their own axes, and several bumps 48 on the rotating disk 21 sequentially contact the first support portion 47. The bumps 48 push the first support portion 47 and the swing pipe 57 to swing reciprocally, changing the inclination angle of the nozzle 46, so that the nozzle 46 sprays different positions on the filter cartridge 8. The nozzle 46 flushes the fiber fabric blocked on the filter cartridge 8, and the scraper 20 cleans the inner wall of the filter cartridge 8. The cleaned fiber fabric falls onto the cleaning hopper 11 through the impurity discharge hopper 31, and the filtered fiber fabric can be discharged through the cleaning hopper 11. When the rotating disk 21 and the filter cartridge 8 rotate relative to the scraper 20, the rotating disk 21 drives the guide ring 34 to rotate relative to the guide groove 35 and the mounting strip 33. Through the design of the guide ring 34 and the guide groove 35, the possibility of the mounting strip 33 tilting and shaking relative to the rotating disk 21 is reduced. When it is necessary to drive the filter cartridge 8 away from the cleaning station, the hydraulic expansion rod 42 drives the movable block 40 to move in the reverse direction. The movable block 40 drives the stop plate 37 to move through the slider 38. The stop plate 37 pushes the sealing plate 36 to rotate relative to the rotating base 5, so that the sealing plate 36 seals the impurity discharge hopper 31 again. When the rotating base 5 rotates again, the rotating base 5 can drive the slider 38 to slide into the chute 41 on the arc-shaped slide rail 39 through the stop plate 37.

[0043] Embodiment 4, based on Embodiment 3, is given by Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 10 . The secondary filtration mechanism includes a filter plate 12 arranged below the filter cylinder 8. Support shafts 13 are fixedly connected to both sides of the filter plate 12. The support shafts 13 are rotatably connected to the multi-stage treatment tank 1. Two first damping plates 14 are arranged outside the multi-stage treatment tank 1, and the two first damping plates 14 are respectively fixedly connected to the corresponding two support shafts 13. Two first servo motors 15 are fixedly connected to the outer wall of the multi-stage treatment tank 1. The output end of the first servo motor 15 is fixedly connected to a second damping plate 16, and the second damping plate 16 is in contact with the corresponding first damping plate 14. The multi-stage treatment tank 1 is equipped with a stopper adapted to the filter plate 12, and one ends of the two filter plates 12 close to each other are both located above the cleaning hopper 11. The stopper includes a shielding plate 17 fixedly installed on the top of the filter plate 12. A stopper post 18 is arranged above the shielding plate 17. The stopper post 18 is fixedly connected to the inner wall of the multi-stage treatment tank 1. A receiving groove 19 adapted to the stopper post 18 is formed on the shielding plate 17. A diversion plate 10 is arranged above the filter plate 12, and the diversion plate 10 is inclined. The diversion plate 10 is fixedly connected to the rotating base 5. The chemical agent stirring structure includes two stirring shafts 51 rotatably installed in the multi-stage treatment tank 1. The stirring shafts 51 are located below the chemical agent adding pipe 2. A number of stirring blades 52 are fixedly connected to the stirring shafts 51. Third sprockets 53 are fixedly installed on the stirring shafts 51 outside the multi-stage treatment tank 1. The two third sprockets 53 are driven by a second chain 54. A fourth servo motor 55 is fixedly connected to the outer wall of the multi-stage treatment tank 1, and the output end of the fourth servo motor 55 is fixedly connected to one of the corresponding third sprockets 53. A number of chemical agent outlet heads 3 are fixedly installed on the chemical agent adding pipe 2 inside the multi-stage treatment tank 1, and the chemical agent outlet heads 3 are located above the chemical agent stirring structure;

[0044] The wastewater after primary filtration flows to the filter plate 12 through the diversion plate 10, and the wastewater is filtered by the filter plate 12. Moreover, the horizontal position of one end of the two filter plates 12 away from each other is lower than the horizontal position of one end of the two filter plates 12 close to each other. Through the design of the baffle plate 17, the possibility that the impurities filtered out by the filter plate 12 fall from the edge of the filter plate 12 is reduced. When it is necessary to clean the impurities on the filter plate 12, the second damping disc 16 is driven to rotate by the first servo motor 15, and the second damping disc 16 drives the first damping disc 14 to rotate through friction, so that the horizontal position of one end of the two filter plates 12 close to each other is lowered. When the horizontal position of one end of the two filter plates 12 away from each other is higher than the horizontal position of one end of the two filter plates 12 close to each other, the filter plate 12 is in an inclined state. The receiving groove 19 on the baffle plate 17 contacts the stop post 18, and the positions of the baffle plate 17 and the filter plate 12 are limited by the stop post 18, so that the filter plate 12 stops rotating, and the instantaneous impact force generated shakes off the impurities on the filter plate 12. By periodically driving the second damping disc 16 to rotate forward and backward by the first servo motor 15, the impurities can roll from the filter plate 12 onto the cleaning hopper 11, and the filtered impurities are discharged through the cleaning hopper 11. The wastewater filtered by the filter cylinder 8 is diverted through the diversion plate 10 to ensure that the filtered wastewater can flow to the filter plate 12. The corresponding third sprocket 53 is driven to rotate by the fourth servo motor 55, and the third sprocket 53 drives another third sprocket 53 to rotate synchronously through the second chain 54. The third sprocket 53 can drive the stirring blade 52 to rotate through the stirring shaft 51, and the stirring blade 52 can stir and mix the wastewater and the flocculant in the multi-stage treatment tank 1. Through a plurality of medicine outlet heads 3 provided, it is convenient to put the flocculant into different positions in the multi-stage treatment tank 1.

[0045] This embodiment also provides a wastewater treatment process for a water jet loom, which is applied to the wastewater treatment equipment for a water jet loom as described above, and includes the following steps:

[0046] Step 1: The wastewater to be treated enters the filter cylinder 8 through the water inlet unit, and the filter cylinder 8 filters the fiber fabrics in the wastewater. The wastewater after primary filtration is filtered for large-particle impurities through the secondary filtration mechanism, and the wastewater after secondary filtration flows to the lower half of the multi-stage treatment tank 1.

[0047] Step 2: The flocculant is added into the multi-stage treatment tank 1 through the medicine adding pipe 2, and the wastewater and the flocculant in the multi-stage treatment tank 1 are stirred by the medicine stirring structure, so that the wastewater and the flocculant are fully mixed.
