[0011] Preferably, there are two cavities, each with two slots on its inner wall. The outer walls of the two fixed blocks and the sides of the multiple wedge blocks are connected to the inner walls of the two cavities, and the multiple wedge blocks are engaged with the multiple slots. The sides of the multiple movable plates are elastically connected by an elastic element.

[0012] Preferably, each of the two fixed blocks has a cavity three inside, and each of the two cavity three has a movable block slidably installed on its inner wall. Each of the two movable blocks has a connecting plate fixedly installed on its bottom surface.

Each of the two connecting plates has a connecting rod hinged to its lower end, and the other ends of the multiple connecting rods are respectively hinged to the sides of the multiple movable plates.

[0013] Preferably, the top surfaces of the two movable blocks are elastically connected to the upper inner walls of the two cavities three through elastic element two, and two pull rods are fixedly installed on the top surfaces of the two movable blocks respectively. The upper ends of the multiple pull rods slide through the upper inner walls of the two cavities three and extend to the top of the fixed block. Two handles are fixedly installed on the upper ends of the multiple pull rods.

[0014] Preferably, a motor is fixedly installed on the top surface of the cover plate, and a rotating shaft is fixedly installed on the output end of the motor.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model allows users to hold the handle and pull it, which in turn moves the pull rod, the moving block, and the connecting plate. The connecting plate then moves the connecting rod, which in turn moves the moving plate and the wedge block. The wedge block moves out of the second cavity, thus no longer being locked in the second cavity. The filter screen can then be removed by simply lifting the handle, making the filter screen disassembly process simple and convenient, facilitating the cleaning and replacement of the filter screen.

[0018] The motor drives the rotating shaft and multiple stirring rods to rotate, ensuring that the filtered liquid is thoroughly stirred. This prevents solid matter from settling on the filter screen and causing clogging, thus improving the filtration efficiency. The elastic elements on the three pairs of circular plates, fixed rods, and scraper apply elastic force, ensuring that the scraper is in close contact with the top surface of the filter screen. Simultaneously, the rotating shaft drives the scraper to rotate, thereby scraping away solids on the filter screen and preventing clogging, further improving the filtration efficiency.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figures 1-6 As shown, this application provides a filter, including: a body 1, a cover plate 101 fixedly installed on the top surface of the body 1 by bolts, an inlet 102 through the top surface of the cover plate 101, an outlet 103 through the outer wall of the body 1, a fixing ring 104 fixedly installed on the inner wall of the body 1, and a filter screen 105 slidably installed on the top surface of the fixing ring 104.

[0032] Specifically, such as Figures 1-6 As shown, a sealing groove 107 is provided on the top surface of the fixing ring 104, and a sealing ring 106 is fixedly installed on the bottom surface of the filter screen 105. The outer wall of the sealing ring 106 is slidably connected to the inner wall of the sealing groove 107, and a discharge window 108 is slidably installed through the outer wall of the machine body 1.

[0033] In this embodiment: the discharge window 108 facilitates the removal of filtered impurities, and the sealing ring 106 and sealing groove 107 seal the filter screen 105 with the fixing ring 104, making it difficult for impurities to penetrate the filter screen 105 and improving the filtration quality.

[0034] Installation mechanism 2 is located inside the body 1. Installation mechanism 2 includes a fixing block 202 that is fixedly installed through the top surface of filter screen 105. A wedge block 205 is provided inside the fixing block 202. A cavity 206 is opened on the top surface of filter screen 105. Installation mechanism 2 is used to fix filter screen 105.

[0035] Specifically, such as Figures 1-6As shown, two handles 201 are fixedly installed on the top surface of the filter screen 105, and two fixing blocks 202 are provided. A cavity 203 is opened inside the two fixing blocks 202. Two movable plates 204 are slidably installed on the inner wall of the two cavities 203 respectively. Multiple wedge blocks 205 are provided. The sides of the multiple wedge blocks 205 are fixedly connected to the sides of the multiple movable plates 204 respectively. The sides of the multiple wedge blocks 205 slide through the inner wall of the two cavities 203 and extend to the outside of the fixing blocks 202.

[0036] In this embodiment: the handle 201 facilitates the lifting and removal of the filter screen 105, and the cavity 203 allows the moving plate 204 to move more smoothly.

[0037] Specifically, such as Figures 1-6 As shown, there are two cavities 206. The inner walls of the two cavities 206 are respectively provided with two slots 207. The outer walls of the two fixed blocks 202 and the sides of the multiple wedge blocks 205 are respectively connected to the inner walls of the two cavities 206. The multiple wedge blocks 205 are respectively engaged with the multiple slots 207. The sides of the multiple movable plates 204 are elastically connected by the elastic element 208.

[0038] In this embodiment, multiple wedge-shaped blocks 205 are respectively engaged with multiple slots 207 to fix the fixing block 202 and the filter screen 105, thereby facilitating the installation of the filter screen 105.

[0039] Specifically, such as Figures 1-6 As shown, each of the two fixed blocks 202 has a cavity 211 inside. Each of the two cavities 211 has a movable block 212 slidably installed on its inner wall. Each of the two movable blocks 212 has a connecting plate 210 fixedly installed on its bottom surface. The lower ends of the two connecting plates 210 slide through the lower inner walls of the two cavities 211 and extend into the cavity 203. Each of the two connecting plates 210 has a connecting rod 209 hinged to its lower end. The other ends of the multiple connecting rods 209 are hinged to the sides of multiple movable plates 204.

[0040] In this embodiment: the connecting plate 210 moves, which drives the connecting rod 209 to move. The connecting rod 209 drives the moving plate 204 and the wedge block 205 to move, thereby adjusting the position of the wedge block 205.

[0041] Specifically, such as Figures 1-6 As shown, the top surfaces of the two movable blocks 212 are elastically connected to the upper inner walls of the two cavities 211 via elastic element 215. Two pull rods 213 are fixedly installed on the top surfaces of the two movable blocks 212 respectively. The upper ends of the multiple pull rods 213 slide through the upper inner walls of the two cavities 211 and extend to the top of the fixed block 202. Two handles 214 are fixedly installed on the upper ends of the multiple pull rods 213.

[0042] In this embodiment: the pull handle 214 drives the pull rod 213 and the moving block 212 to move, thereby driving the connecting plate 210 to move, and the elastic element 215 applies elastic force to the moving block 212.

[0043] The stirring mechanism 3 is located above the filter screen 105. The stirring mechanism 3 includes a stirring rod 303 located inside the body 1, and a scraper 309 is provided below the stirring rod 303. The stirring mechanism 3 is used to stir the sewage.

[0044] Specifically, such as Figures 1-6 As shown, a motor 301 is fixedly installed on the top surface of the cover plate 101, and a rotating shaft 302 is fixedly installed at the output end of the motor 301. The lower end of the rotating shaft 302 rotates through the top surface of the cover plate 101 and extends into the interior of the machine body 1 via the first bearing seat. Multiple stirring rods 303 are provided. One end of the multiple stirring rods 303 is fixedly connected to the outer wall of the rotating shaft 302, and multiple through holes are opened on the side of the multiple stirring rods 303.

[0045] In this embodiment: the motor 301 drives the rotating shaft 302 and the stirring rod 303 to rotate, so that the filtered liquid is fully stirred, and solid substances are less likely to settle on the filter screen 105, causing the filter screen 105 to become clogged, thereby improving the filtration effect of the filter screen 105.

[0046] Specifically, such as Figures 1-6 As shown, two rotating rods 304 are fixedly installed on the lower outer wall of the rotating shaft 302. Two grooves 305 are respectively opened inside the two rotating rods 304. Circular plates 306 are slidably installed on the inner walls of the grooves 305. The top surfaces of the circular plates 306 are elastically connected to the upper inner walls of the grooves 305 through elastic elements 307. Fixed rods 308 are fixedly installed on the bottom surfaces of the circular plates 306. The lower ends of the fixed rods 308 slide through the lower inner walls of the grooves 305 and extend below the rotating rods 304. Two scraper rods 309 are provided. The bottom surfaces of the two scraper rods 309 are slidably connected to the top surface of the filter screen 105, and the top surfaces of the two scraper rods 309 are fixedly connected to the lower ends of the fixed rods 308.

[0047] In this embodiment: the elastic element 307 applies a pushing force to the circular plate 306, the fixing rod 308 and the scraper 309, and the scraper 309 scrapes off the impurities on the filter screen 105.

[0048] Specifically, this solution involves adding the filter liquid through the inlet 102, turning on the motor 301, which drives the rotating shaft 302 and multiple stirring rods 303 to rotate, thus fully agitating the filter liquid. This prevents solid matter from settling on the filter screen 105 and causing clogging, thereby improving the filtration efficiency of the filter screen 105. The elastic element 307 applies elastic force to the circular plate 306, the fixed rod 308, and the scraper 309, ensuring close contact between the scraper 309 and the top surface of the filter screen 105. Simultaneously, the rotating shaft 302 drives the scraper 309 to rotate, thereby scraping away solids from the filter screen 105, preventing clogging. The filter screen 105 is plugged in to further improve its filtration efficiency. After filtration is completed, the cover plate 101 is opened. By holding the handle 201, the pull handle 214 is pulled, which moves the pull rod 213, the moving block 212 and the connecting plate 210. The connecting plate 210 moves the connecting rod 209, which in turn moves the moving plate 204 and the wedge block 205. The wedge block 205 moves out of the cavity 206, so that the wedge block 205 is no longer stuck with the cavity 206. The filter screen 105 can be removed by holding the handle 201, making the disassembly process of the filter screen 105 simple and convenient, so as to facilitate the cleaning and replacement of the filter screen 105.
