[0035] It further includes a filter cylinder 2 connected to the inner side of the upper end of the water tank 1. A filter element 4 is provided at the bottom end of the filter cylinder 2 for intercepting and filtering the garbage in the sewage to purify the sewage.
[0036] The filter element 4 includes an intercepting filter plate 42 movably arranged in the filter cylinder 2. The intercepting filter plate 42 is used for filtering the garbage in the sewage, and the garbage in the sewage is intercepted at the upper end of the intercepting filter plate 42. A lifting partition plate 6 is fixedly connected to the upper end of the intercepting filter plate 42. A lifting mechanism 7 for driving the lifting partition plate 6 is provided on the filter cylinder 2. The lifting mechanism 7 includes second cylinders 72 installed on both side walls of the filter cylinder 2. A connecting plate 71 is fixedly connected to the upper end of the lifting partition plate 6. The telescopic ends of the two second cylinders 72 are respectively fixedly connected to both ends of the connecting plate 71. The lifting state of the lifting partition plate 6 is controlled by the two second cylinders 72, and then the lifting state of the intercepting filter plate 42 is controlled. Among them, the filter element 4 further includes a filter plate 41 connected to the bottom end of the filter cylinder 2. A plurality of drainage holes are opened on the filter plate 41. The intercepting filter plate 42 is located above the filter plate 41, and a plurality of drainage grooves are opened at the upper end of the intercepting filter plate 42.
[0037] An extrusion assembly 3 for extruding the water quality in the garbage is provided on the filter cylinder 2. The extrusion assembly 3 is provided in two groups. The two groups of extrusion assemblies 3 are respectively located on both sides of the lifting partition plate 6, and both groups of extrusion assemblies 3 are located above the intercepting filter plate 42.
[0038] Specifically, the extrusion assembly 3 includes a mounting frame 31 fixedly connected to the upper end of the filter cartridge 2. A first cylinder 33 is mounted on the lower surface of the mounting frame 31. The lower end of the first cylinder 33 is fixedly connected to a pressing plate 32, and the pressing plate 32 is used to extrude the water quality in the garbage at the upper end of the intercepting filter plate 42. When it is necessary to discharge the garbage at the upper end of the intercepting filter plate 42, the two first cylinders 33 are started, so that the telescopic ends of the two first cylinders 33 extend to drive the two pressing plates 32 to move downward, extruding the garbage at the upper end of the intercepting filter plate 42, so that the water quality in the garbage passes through the intercepting filter plate 42 and the filter plate 41 and is discharged into the water tank 1, making the solid-liquid separation more thorough.
[0039] In this embodiment, a water inlet pipe 11 is connected to the side wall of the filter cartridge 2. The water inlet pipe 11 is located between the intercepting filter plate 42 and the pressing plate 32, so that sewage flows into the space between the pressing plate 32 and the intercepting filter plate 42. At least two water inlet pipes 11 are provided, and the two water inlet pipes 11 are respectively located on both sides of the lifting partition plate 6. One end of the water inlet pipe 11 penetrates through the side wall of the water tank 1, and the input end of the water inlet pipe 11 is connected to an external sewage discharge pipe.
[0040] Embodiment 2
[0041] A sewage treatment device for purifying domestic sewage proposed by the present utility model is based on Embodiment 1. As Figures 2-3 shown, this embodiment further includes: cleaning members 5 are arranged on both sides of the lifting partition plate 6 in the filter cartridge 2. Wings 8 are fixedly connected to the upper ends of both sides of the water tank 1. Through holes 9 communicating with the filter cartridge 2 are opened on the side walls of the two wings 8. Guide covers 10 are fixedly connected to the outer side walls of the two wings 8 and are located outside the through holes 9, which play a role in guiding and discharging the garbage intercepted in the filter cartridge 2.
[0042] A connecting groove 53 is opened on the lower side wall of the lifting partition plate 6. A push plate 54 is inserted into the connecting groove 53. A pulling plate 51 extending to the inner wall of the water tank 1 is fixedly connected to one side of the push plate 54. A hook groove 52 is opened at one end of the pulling plate 51 close to the side wall of the water tank 1. Among them, after the push plate 54 is clamped in the connecting groove 53, the outer surface of the push plate 54 is perpendicular and flush with the outer surface of the lifting partition plate 6, and it will not hinder the downward movement of the pressing plate 32 (extruding the garbage). At this time, the outer end of the pulling plate 51 contacts the inner wall of the water tank 1. The size of the push plate 54 matches the size of the through hole 9, and it can slide through the through hole 9 into the guide cover 10.
[0043] The working principle of this application is as follows: Domestic sewage is discharged into the filter cartridge 2 through two inlet pipes 11. The water level of the sewage in the filter cartridge 2 is below the pressing plate 32. The sewage in the filter cartridge 2 flows into the water tank 1 through filtration by the intercepting filter plate 42 and the filter plate 41, and the garbage in the sewage is intercepted at the upper end of the intercepting filter plate 42. When it is necessary to discharge the garbage in the filter cartridge 2, the garbage is first squeezed. Specifically, two first cylinders 33 are started, the telescopic ends of the two first cylinders 33 extend, driving the two pressing plates 32 to move downward, squeezing the garbage at the upper end of the intercepting filter plate 42, squeezing the water in the garbage into the water tank 1, and after the squeezing is completed, the telescopic ends of the two first cylinders 33 retract to their original states, thereby driving the two pressing plates 32 to rise to their original positions.
[0044] Next, two second cylinders 72 and two first cylinders 33 are started simultaneously, the two second cylinders 72 extend, and the two first cylinders 33 retract, synchronously driving the lifting partition plate 6, the intercepting filter plate 42, and the two pressing plates 32 to move upward (during the rising process, the distance between the pressing plate 32 and the intercepting filter plate 42 remains unchanged) until the two pushing plates 54 move to one side of the two through ports 9. Then, an external hook is used to hook the hook groove 52, and the two pull-out plates 51 are pulled outwards, thereby causing the two pushing plates 54 to move away from each other, pushing the garbage in the filter cartridge 2 outwards, and finally discharging it through the two guiding covers 10. After the garbage is discharged, the two pushing plates 54 are pushed into the two connecting grooves 53, and then two first cylinders 33 and two second cylinders 72 are started to lower the intercepting filter plate 42 and the two pressing plates 32 to their initial states to facilitate continuous sewage treatment.
[0045] The above specific embodiments are only the preferred embodiments of this application. Based on the technical solution of this application and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments; the above specific embodiments are only explanations of this application and do not limit this application.
