[0039] A filtering mechanism 2 is arranged at one end of the reservoir 1, which is used for filtering and treating the sewage in the reservoir 1, and comprises a filtering component 21 and a cleaning component 22, the filtering component 21 is arranged in the inner cavity of the reservoir 1, and the cleaning component 22 is arranged at the upper end of the reservoir 1.

[0040] As an embodiment of the present application, in order to solve the problem that the existing filter plate causes impurities to flow back to sewage when cleaning impurities, the present application designs a filtering component 21, specifically: the filtering component 21 includes a filtering belt 211, three transmission rollers 212 and two drive motors 213, the three transmission rollers 212 are installed in reverse triangle shape on the water storage pool 1, the filtering belt 211 is sleeved on the three transmission rollers 212, so that the filtering belt 211 forms a reverse triangle shape, the filtering belt 211 can be a flexible material resistant to corrosion, such as flexible stainless steel sheet, a plurality of filtering holes 214 are evenly distributed on the outer side of the filtering belt 211, the hole diameter of the filtering holes 214 gradually decreases from the outer side to the inner side of the filtering belt 211, the drive motor 213 is fixedly installed on the outer side of the water storage pool 1, the output end of the drive motor 213 is fixedly connected with the rotating end of one of the transmission rollers 212, the sewage passes through the filtering belt 211 twice, because the sewage first passes through the outer side of the filtering belt 211, at this time the hole diameter of the filtering holes 214 decreases from large to small, then the sewage passes through the inner side of the filtering belt 211, the hole diameter of the filtering holes 214 increases from small to large, on the one hand, the twice filtering function of the sewage is realized, which is beneficial to fully filter the impurities in the sewage; on the other hand, the functions of coarse filtering and fine filtering of the sewage can be realized, the impurities in the sewage can be filtered in stages, which is beneficial to improve the filtering effect of the sewage;

[0041] When the filtering component 21 filters the sewage, the sewage first passes through the outer side of the filtering belt 211 close to the water retaining plate 5, because the hole diameter of the filtering holes 214 at this position decreases from large to small, the larger impurities are intercepted, and the smaller impurities continue to flow with the sewage, completing the coarse filtering treatment of the sewage, then the sewage continues to flow through the inner side of the filtering belt 211, at this time the hole diameter of the filtering holes 214 increases from small to large, the smaller impurities in the sewage can be intercepted, and then the fine filtering treatment of the sewage is completed, after the coarse filtering and fine filtering treatment of the sewage for two times, most of the impurities in the sewage can be filtered out, not only the filtering function of the sewage is realized, but also the filtering effect is better; when it is necessary to clean the impurities on the filtering belt 211, the two drive motors 213 are rotated to drive the corresponding transmission rollers 212 to rotate at the same time, and then drive the filtering belt 211 to move, so that the inclined section of the filtering belt 211 close to the water retaining plate 5 moves to the position of the upper horizontal section, while the other inclined section of the filtering belt 211 moves close to the water retaining plate 5, and the initial horizontal section of the filtering belt 211 moves to the inclined section position, at this time, the new two inclined sections of the filtering belt 211 continue to filter the sewage, and the cleaning component 22 starts to clean the impurities adsorbed on the horizontal section of the filtering belt 211, so repeating the operation can keep the filtering effect of the filtering belt 211 normal;

[0042] In the filter part 21 of the present application, by arranging the filter belt 211, the traditional filter plate structure form is changed, and the driving roller 212 and the driving motor 213 are arranged to form an active inverted triangular filter structure. When filtering sewage normally, the sewage passes through the two inclined sections of the filter belt 211 in sequence, which not only realizes the twice filtering function of the sewage, but also is beneficial to filter the impurities in the sewage; and also can realize the function of coarse filtering and fine filtering of the sewage, which can filter the impurities in the sewage in stages, and is beneficial to improve the filtering effect of the sewage; when it is necessary to clean the impurities on the filter belt 211, the part of the filter belt 211 that needs to be cleaned is driven to the horizontal position, at this time, the horizontal section of the filter belt 211 is at the top of the water storage tank 1 and no longer contacts with the sewage, so when the cleaning part 22 is used to clean the impurities, it is beneficial to avoid the impurities flowing back to the sewage, which improves the filtering effect of the filter belt 211, and at the same time, the two inclined sections of the filter belt 211 are in the sewage, which continues to filter the sewage, so that the normal filtering of the filter belt 211 is not affected during the cleaning process of the filter belt 211.

[0043] As an embodiment of the present application, in order to ensure that the filter belt 211 can be used normally for a long time, it is necessary to clean the impurities adsorbed on the inner and outer sides of the filter belt 211, therefore, the cleaning part 22 matched with the structure of the filter belt 211 is designed, which is specifically: the cleaning part 22 is used to clean the inner and outer sides of the filter belt 211 and the filter hole 214, so that the filter belt 211 can maintain normal filtering state; the cleaning part 22 includes an outer side scraping assembly 221, an inner side scraping assembly 222, a hole cleaning assembly 223 and a collection assembly 224, the outer side scraping assembly 221 is used to scrape and clean the impurities adsorbed on the outer side of the horizontal section of the filter belt 211, the inner side scraping assembly 222 is used to scrape and clean the impurities adsorbed on the inner side of the horizontal section of the filter belt 211, the hole cleaning assembly 223 is used to clean the impurities in the filter hole 214 on the horizontal section of the filter belt 211, and the collection assembly 224 is used to collect the impurities cleaned by the outer side scraping assembly 221;

[0044] The outer side scraping assembly 221 comprises a support frame 2211 and a connecting piece 2212, one end of the support frame 2211 is fixedly installed with a rotating motor 2213, the top of the support frame 2211 is provided with a sliding groove 2214, the output end of the rotating motor 2213 is fixedly installed with a threaded rod 2215, one end of the threaded rod 2215 rotates through one end of the support frame 2211 and extends into the sliding groove 2214, one end of the threaded rod 2215 is rotatably connected with one side of the inner surface of the sliding groove 2214, the top end of the connecting piece 2212 is slidably connected with the inner side of the sliding groove 2214, the top end of the connecting piece 2212 is threadedly connected with the outer side of the threaded rod 2215, and the bottom of the connecting piece 2212 is fixedly installed with two symmetrically distributed electric push rods 2216, and the telescopic ends of the two electric push rods 2216 are commonly fixedly installed with a cleaning scraper 2217. The height of the cleaning scraper 2217 is adjusted by the electric push rod 2216, so that the cleaning scraper 2217 can be in contact with and separated from the horizontal section of the filter belt 211. When the outer side scraping assembly 221 is used to clean the horizontal section of the filter belt 211, the electric push rod 2216 is first elongated, which drives the scraping plate to move downward, so that the bottom of the scraping plate is flush with the horizontal section of the filter belt 211. The rotating motor 2213 is positively rotated, which drives the threaded rod 2215 to rotate synchronously. The top of the connecting piece 2212 is limited by the sliding groove 2214, so that when the threaded rod 2215 rotates, the connecting piece 2212 moves horizontally along the upper end of the support frame 2211, and the electric push rod 2216 and the scraping plate move horizontally together. The scraping plate can scrape and move the impurities adsorbed on the filter belt 211 by sliding contact between the bottom of the scraping plate and the horizontal section of the filter belt 211, until the impurities are moved to the collecting assembly 224, and then the cleaning operation of the filter belt 211 is completed. Then, the electric push rod 2216 is retracted, which drives the cleaning scraper 2217 to move upward and separate from the horizontal section of the filter belt 211. The rotating motor 2213 is reversely rotated, which drives the cleaning scraper 2217 to move back to the original position.

[0045] The inner scraping assembly 222 comprises a collecting box 2221 fixedly installed on the support frame 2211, the collecting box 2221 is located below the horizontal section of the filter belt 211, the upper end of the collecting box 2221 is fixedly installed with two fixed scrapers 2222 arranged side by side, the fixed scrapers 2222 are obliquely arranged and used for guiding the impurities cleaned to the collecting box 2221, and the top end of the fixed scrapers 2222 is in abutment with the inner side of the filter belt 211; in use, the inner scraping assembly 222 is in sliding contact with the top end of the fixed scrapers 2222 through the movement of the filter belt 211, thereby scraping off the impurities adsorbed on the inner side of the filter belt 211, and then the impurities scraped off flow downward from the fixed scrapers 2222 to the collecting box 2221, thereby completing the cleaning operation on the inner side of the filter belt 211; since the inner scraping assembly 222 is fixedly arranged, the inner scraping assembly 222 can automatically clean the inner side of the filter belt 211 when the filter belt 211 moves, and thus the cleaning operation is more convenient without artificial control.

[0046] The collecting assembly 224 comprises a collecting hopper 2241 fixedly installed at the end of the water storage tank 1, one end of the collecting hopper 2241 is in abutment with the outer side of the filter belt 211, and the collecting hopper 2241 is obliquely arranged; the collecting hopper 2241 is in sliding abutment with the outer side of the filter belt 211, the end of the collecting hopper 2241 can also scrape the surface of the filter belt 211, thereby achieving the secondary scraping and cleaning function on the outer surface of the filter belt 211 and improving the cleaning effect on the outer side of the filter belt 211; the other end of the collecting hopper 2241 is slidingly installed with a baffle 2242, the baffle 2242 is used for plugging the port of the collecting hopper 2241, thereby preventing the impurities in the collecting hopper 2241 from flowing out, and when the impurities in the collecting hopper 2241 need to be cleaned, the baffle 2242 can be pulled upward to separate the baffle 2242 from the collecting hopper 2241, thereby cleaning the impurities out of the collecting hopper 2241.

[0047] As one of the embodiments of the present application, when the collecting assembly 224 collects the scraped impurities, in order to avoid the problem that the impurities accumulate at the inlet end of the collecting hopper 2241, causing the impurities to be unable to be normally collected, the present application further improves the specific form of the filter belt 211 and the collecting hopper 2241, specifically: a guide plate 2243 is rotatably installed at one end of the collecting hopper 2241 close to the filter belt 211, one end of the guide plate 2243 is in sliding fit with the outside of the filter belt 211, and the guide plate 2243 can scrape the movable filter belt 211 to achieve the purpose of impurity cleaning. Two supporting springs 2244 are fixedly installed between the bottom of the guide plate 2243 and the inside of the collecting hopper 2241, the supporting springs 2244 provide elastic support for the guide plate 2243, so that the guide plate 2243 can be automatically reset. A poking piece 2245 is fixedly installed at the top of the guide plate 2243, the poking piece 2245 extends upward to the outside of the inlet end of the collecting hopper 2241, and an active slot 2246 that is matched with the poking piece 2245 is formed at the top of the collecting hopper 2241; when the cleaning scraper 2217 pushes the impurities on the filter belt 211 into the collecting hopper 2241, the impurities first move into the guide plate 2243, and as the cleaning scraper 2217 continues to push, the side of the poking piece 2245 contacts the cleaning scraper 2217 and pushes the poking piece 2245 to move together. Then the poking piece 2245 starts to move into the active slot 2246, so that the poking piece 2245 starts to drive the guide plate 2243 to rotate in the collecting hopper 2241, and the supporting springs 2244 are squeezed and start to contract. As the guide plate rotates, its inclination angle gradually increases, so that the impurities accumulated thereon can fall downward and finally flow into the collecting hopper 2241, until the cleaning scraper 2217 reaches the final position and stops moving, so that the guide plate 2243 also stops rotating. Then the cleaning scraper 2217 moves back to the original position, and under the action of the elastic force of the supporting springs 2244, the guide plate 2243 also rotates back to the original position. Therefore, by arranging the guide plate 2243, the supporting springs 2244 and the poking piece 2245, a flow guide structure for the impurities is formed, the movement of the cleaning scraper 2217 drives the poking piece 2245 to move, and finally the guide plate 2243 rotates, so that the accumulated impurities can be poured into the collecting hopper 2241. Thus, the automatic flow guide function of the impurities is realized while the cleaning scraper 2217 scrapes, which is beneficial to avoid the problem that the impurities accumulate at the inlet end of the collecting hopper 2241, so that the impurities can smoothly enter the collecting hopper 2241.

[0048] As an embodiment of the present application, during normal filtering use of the filter belt 211, impurities may block in the filter holes 214, thereby causing the filter belt 211 to fail to normally filter, therefore, in order to solve this problem, the present application further designs the hole cleaning assembly 223 according to the specific structure of the filter holes 214, specifically: the hole cleaning assembly 223 includes a lifting plate 2231 and two bottom plates 2232, the lifting plate 2231 is arranged directly below the horizontal section of the filter belt 211, the two bottom plates 2232 are arranged below the lifting plate 2231, and the two ends of the bottom plate 2232 are fixedly installed on both sides of the top of the water storage pool 1, the top of the bottom plate 2232 is fixedly installed with a gas cylinder 2233, the telescopic end of the gas cylinder 2233 is fixedly connected with the bottom of the lifting plate 2231, the top of the lifting plate 2231 is threadedly installed with a plurality of uniformly distributed hole cleaning pieces 2234, and the hole cleaning pieces 2234 correspond one-to-one with the filter holes 214 on the horizontal section of the filter belt 211; the hole cleaning piece 2234 includes a mounting rod 22341 and a cleaning head 22342, the bottom end of the mounting rod 22341 is threadedly connected with the top of the lifting plate 2231, facilitating replacement of the hole cleaning piece 2234, and the cleaning head 22342 is fixedly installed at the top end of the mounting rod 22341; the upper and lower ends of the cleaning head 22342 are symmetrically arranged in a conical shape, the cleaning head 22342 is made of an elastic material such as rubber material, and the conical cleaning head 22342 can adapt to the filter holes 214 at the position of the horizontal section of the filter belt 211 and can smoothly enter and exit the filter holes 214 which are narrow at the bottom and wide at the top; when it is necessary to clean the filter belt 211, first, the inside of the filter hole 214 is cleaned through the hole cleaning assembly 223, at this time, the gas cylinder 2233 is elongated, which can drive the lifting plate 2231 and the hole cleaning piece 2234 thereon to move upward together, so that the hole cleaning piece 2234 gradually approaches the filter hole 214 above, the cleaning head 22342 first contacts the lower end of the filter hole 214, then is extruded to deform, and continues to extend into the filter hole 214, after the cleaning head 22342 enters the inside of the filter hole 214, the outside of the cleaning head 22342 can be tightly attached to the inside of the filter hole 214 by virtue of the elasticity of the cleaning head 22342 itself, thereby pushing all impurities adsorbed on the inside and the inside of the filter hole 214 outward, realizing the impurity cleaning function of the filter hole 214, the impurities are pushed to the outside of the filter belt 211, the gas cylinder 2233 stops elongating, so that the cleaning head 22342 is temporarily left in the filter hole 214, then the cleaning scraper 2217 slides on the surface of the filter belt 211, which can scrape and clean the impurities on the surface of the filter belt 211, and during the scraping process, since the cleaning head 22342 is still in the filter hole 214, the impurities can be prevented from falling back into the filter hole 214, after the cleaning scraper 2217 reaches the collecting hopper 2241, the gas cylinder 2233 starts to contract, which can drive the lifting plate 2231 and the hole cleaning piece 2234 to move downward, and the cleaning head 22342 is separated from the filter hole 214.By setting the hole cleaning assembly 223, mainly used for automatic cleaning of impurities existing in the filter hole 214, the impurities in the filter hole 214 can be cleaned to the surface of the filter belt 211, and then the cleaning scraper 2217 is used for centralized cleaning, solving the problem of impurities blocking the filter hole 214, which is beneficial to improve the cleaning effect of the cleaning part 22 on the filter belt 211, so that the filter belt 211 maintains normal filtering effect.
