[0047] Two mounting holes are provided on the rear side of the filter box 1, and a sewage discharge cylinder 11 is installed at each of the two mounting holes. A discharge pipe 12 is installed at the lower side of the sewage discharge cylinder 11 away from the end of the filter box 1. The primary sewage discharge assembly 13 is used in conjunction with the filter assembly 14 and the sewage discharge cylinder 11.

[0048] A base 15 is installed inside the filter box 1. The base 15 is suspended and fixed inside the filter box 1 and is located below the filter assembly 14. The cutting and separation assembly 16 and the scraping assembly 17 are both installed on the base 15. The cutting and separation assembly 16 and the scraping assembly 17 are both driven by a driving motor 21.

[0049] A sewage drain groove is provided on one side of the bottom of the filter box 1, and a sewage drain box 10 is installed on the outer side of the filter box 1 at a position corresponding to the sewage drain groove.

[0050] Furthermore, the filter assembly 14 includes a V-shaped plate 141 fixed inside the filter box 1, and two vertical filter plates 142 are symmetrically fixed to the bottom of the V-shaped plate 141, and an arc-shaped filter plate 143 is fixed to the lower end of each vertical filter plate 142, and a guide plate 144 is fixed to the end of the arc-shaped filter plate 143 away from the vertical filter plate 142, and the upper end of the guide plate 144 is fixed to the inner wall of the filter box 1, and a gap is left between the upper part of the arc-shaped filter plate 143 and the bottom of the vertical filter plate 142, and the front end of the sewage barrel 11 is fixed to the rear ends of the vertical filter plate 142, the arc-shaped filter plate 143 and the guide plate 144 at the same time; filter holes are opened on the vertical filter plate 142 and the arc-shaped filter plate 143.

[0051] like Figure 3 As shown, sewage is divided into two paths from the outlet 201 of the water inlet pipe 2 to enter the filter box 1, wherein the hair is intercepted and filtered by the vertical filter plate 142 and the arc filter plate 143 respectively, and some large particles of impurities are also intercepted. The intercepted hair is then cut by the cutting and separation component 16 and the primary filter component 13 to avoid clogging of the filter holes at various places. The intercepted hair is subsequently cleaned and transported through the primary filter component 13.

[0052] There are two primary filter assemblies 13, and both primary filter assemblies 13 include a rotating shaft 131 and a spiral blade 132 rotatably arranged inside the sewage barrel 11 and the arc filter plate 143, and the spiral blade 132 is fixed on the rotating shaft 131, the front end of the rotating shaft 131 is rotatably mounted on the front side plate of the filter box 1, the rear end of the rotating shaft 131 extends to the rear side of the sewage barrel 11 and is rotatably mounted on the sewage barrel 11, the rear ends of the two rotating shafts 131 are driven by a pulley assembly 133, and a motor 134 is also installed on the rear side of the two sewage barrels 11 through a motor seat, and the drive shaft of the motor 134 and the rear end of one of the rotating shafts 131 are driven by a pulley assembly 133.

[0053] When the motor 2 134 is turned on, the two rotating shafts 131 can be driven to rotate simultaneously through the pulley assembly 2 133, and the spiral blade 132 on the rotating shaft 131 is driven to rotate synchronously. When rotating, it can help to cut the hair on the inner wall of the arc filter plate 143, and can transport large particles and impurities such as hair, so that the impurities can be transported to the sewage barrel 11 and finally discharged from the discharge pipe 12. In addition, after the device has been used for a period of time, the dirt that may be adsorbed on the primary sewage discharge component 13 and the filter component 14 and the vertical filter plate 142 and the arc filter plate 143 can also be cleaned separately by using the cutting separation component 16 and the spiral blade 132 of the primary sewage discharge component 13, and finally transported to the sewage barrel 11 through the spiral blade 132, and finally discharged from the discharge pipe 12.

[0054] Further, a bracket 18 and a guide rail 19 are installed on the base 15, a driving motor 21 is installed on the bracket 18, a main shaft 22 is installed on the driving shaft of the driving motor 21, a rack 20 is slidably installed in the guide rail 19 through a slider 191, a driving gear 23 and a driving bevel gear 25 are installed on the main shaft 22, and the driving gear 23 is meshed with the rack 20 for transmission;

[0055] The cutting and separation assembly 16 includes a sub-shaft 161, which is rotatably mounted on the upper part of the bracket 18, and the sub-shaft 161 passes through the vertical filter plate 142, and a driven gear 24, a cutting blade 162, and a cutting blade 2 163 are mounted on the sub-shaft 161, and the driven gear 24 and the cutting blade 2 163 are both located on a side of the vertical filter plate 142 close to the V-shaped plate 141, and the driven gear 24 is meshed with the rack 20 for transmission, and the cutting blade 2 163 is slidably fitted on a side of the vertical filter plate 142 close to the V-shaped plate 141, and the cutting blade 1 162 is slidably fitted on a side of the vertical filter plate 142 away from the V-shaped plate 141;

[0056] The cutting blade 162 is used to cut the hair on the inner side of the vertical filter plate 142 when rotating, so that the hair can fall to the inner side of the arc filter plate 143, and then be transported to the sewage discharge barrel 11 by the spiral blade 132, and finally discharged from the discharge pipe 12. The cutting blade 162 can also be used to clean the dirt adsorbed on the inner side of the vertical filter plate 142; and the cutting blade 2 163 is used to clean the dirt adsorbed on the outer side of the vertical filter plate 142 when rotating.

[0057] The scraping assembly 17 includes a parallel screw rod 173 and a slide rod 174. The two ends of the screw rod 173 are rotatably mounted on the inner wall of the filter box 1, and the two ends of the slide rod 174 are fixedly mounted on the inner wall of the filter box 1. A plurality of H-shaped frames 171 are threadedly mounted on the screw rod 173. The lower part of each H-shaped frame 171 is slidably mounted on the slide rod 174. An arc scraper 172 is fixed on the upper part of each H-shaped frame 171. Each arc scraper 172 is in frictional contact with the bottom wall of the arc filter plate 143 on the same side. A driven bevel gear 26 is installed on the screw rod 173, and the active bevel gear 25 is meshed with the driven bevel gear 26 for transmission.

[0058] The arc scraper 172 is used to remove dirt from the outer surface (bottom surface) of the arc filter plate 143, so that the dirt can fall to the bottom of the filter box 1 and be cleaned by the secondary sewage assembly 9 later;

[0059] The driving motor 21 adopts a servo motor, and cooperates with the PLC controller to repeatedly control the forward and reverse rotation of the driving motor 21. When the driving main shaft 22 rotates forward and reverse, the driving gear 23 is meshed with the rack 20 to drive the rack 20 to rise and fall relative to the base 15. The meshing transmission between the rack 20 and the driven gear 24 can drive the sub-shaft 161 to rotate. At this time, the cutting blade 1 162 and the cutting blade 2 163 installed on the sub-shaft 161 can rotate repeatedly. Figure 8 As shown, a plurality of cutting blades 162 and cutting blades 163 can be installed at equal intervals on each sub-shaft 161. For example, in this embodiment, three cutting blades 162 and three cutting blades 163 are installed at equal intervals on the sub-shaft 161 at the same time; when the cutting blade 162 rotates, it can cut the hair on the inner side of the vertical filter plate and scrape off the dirt, and the cutting blade 163 can scrape off the dirt on the outer wall of the vertical filter plate;

[0060] When the driving motor 21 drives the main shaft 22 to rotate, the meshing transmission of the active bevel gear 25 and the driven bevel gear 26 can be used to control the rotation of the screw rod 173, and can further drive the arc scraper 172 on the H-shaped frame 171 to move repeatedly relative to the screw rod 173 and the sliding rod 174, so that the moving arc scraper 172 can clean the bottom surface of the arc filter plate, so that the mud and dirt can be scraped off. The scraped mud and dirt fall to the bottom of the filter box 1 and wait to be cleaned by the secondary sewage discharge component 9.

[0061] Furthermore, the secondary sewage discharge assembly 9 includes two screw rods 91 rotatably arranged inside the filter box 1, and one end of the two screw rods 91 away from the sewage discharge box 10 extends to the outside of the filter box 1 and is driven by a pulley assembly 92. A motor 93 is also installed on the outside of the filter box 1, and the drive shaft of the motor 93 and the end of one of the screw rods 91 are driven by a pulley assembly 92;

[0062] A movable plate 94 is threadedly mounted between the two screw rods 91 , and a brush strip 95 is movably mounted below the movable plate 94 . The brush strip 95 is in frictional contact with the inner bottom wall of the filter box 1 . The screw rod 91 , the movable plate 94 and the brush strip 95 are all located below the base 15 .

[0063] Furthermore, the sewage box 10 includes a box body 101 fixed to the outer wall of the filter box 1, and the side of the box body 101 is provided with a receiving groove docking with the sewage trough, and the bottom of the box body 101 is detachably installed with a sealing cover 102, and the end of the screw rod 91 away from the motor 93 extends into the box body 101 and is rotatably installed with the inner wall of the box body 101, and the height of the receiving groove and the sewage trough are both greater than the height of the movable plate 94 and the brush strip 95.

[0064] Furthermore, the vertical cross-section of the movable plate 94 is an inverted T-shaped structure, and multiple positioning shafts 96 are detachably installed on both sides of the bottom of the movable plate 94, the vertical cross-section of the positioning shaft 96 is a T-shaped structure, the brush strip 95 is slidably installed with the positioning shaft 96 through a strip plate with a sliding hole, and a spring 97 is installed on the positioning shaft 96, the lower end of the spring 97 is against the top surface of the strip plate, and the upper end of the spring 97 is against the limit block at the top of the positioning shaft 96.

[0065] The motor 93 is a servo motor, and the forward and reverse rotation is controlled by the PLC controller. The motor 93 can cooperate with the pulley assembly 92 to simultaneously control the rotation of the two screws 91, thereby controlling the moving plate 94 and the brush bar 95 to move back and forth relative to the inner bottom wall of the filter box 1. At this time, the brush bar 95 can clean the dirt deposited at the bottom of the filter box 1. The dirt can be cleaned into the sewage box 10, and when the sealing cover 102 is opened later, the dirt can be completely discharged.

[0066] When it is necessary to remove the dirt in the filter box 1, the available water inside needs to be discharged so that the liquid level is lowered to the water inlet of the liquid outlet pipe 4 as much as possible, thereby reducing the waste of water.

[0067] Furthermore, a plurality of spray pipes 801 are installed inside the filter box 1 and above the filter assembly 14, and a plurality of spray heads are installed below the spray pipes 801. The water inlet of the spray pipes 801 extends to the outside of the filter box 1 and is connected to the flushing pipe 8. The water inlet of the flushing pipe 8 is connected to the water outlet of the water pump 7. The water inlet of the water pump 7 is externally connected to a water supply pipe. In order to quickly clean the dirt in the filter box 1 later, the water pump 7, the flushing pipe 8, the spray pipe 801 and the spray head can be used to spray clean water to the inside of the filter box 1, thereby accelerating the discharge of dirt.

[0068] It should also be noted that both the filter box 1 and the purification box 5 are provided with a removable top cover or side cover, so as to facilitate the replacement or maintenance of the components therein. In order to avoid the redundancy of the content and drawing structure, this application omits the description of the above-mentioned cover body, but the above-mentioned content belongs to the conventional technical means in this field, so the omission of the above-mentioned content will not hinder the implementation of the application.
