Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, specifically a sewage filtration device with a self-cleaning filter structure. Background Technology

[0002] In the wastewater treatment process, filtration is crucial. It can effectively remove solid impurities and suspended solids from wastewater, providing favorable conditions for subsequent advanced treatment. In industrial production and daily life, wastewater filtration is often required.

[0003] Existing wastewater filtration devices mostly use static filter screens. During the filtration process, solid impurities easily adhere to and clog the filter screen mesh, causing the filtration efficiency to drop rapidly. This requires frequent shutdowns for manual cleaning or replacement of the filter screen, which not only increases maintenance costs and affects the efficiency of continuous operation, but also results in low automation of manual cleaning.

By setting a rotating component and a cleaning mechanism, it achieves synchronous and automatic cleaning of the filter cartridge during the filtration process, effectively avoiding the problem of filter cartridge mesh clogging. It eliminates the need for manual intervention and greatly improves sewage treatment efficiency and continuity. Combining the mechanical scraping of the brush rod with the hydraulic flushing of the high-pressure flushing pipe, the device effectively removes stubborn deposits from both inside and outside, ensuring the permeability of the filter screen and improving the sewage filtration effect. The screw conveyor actively lifts and discharges the impurities collected at the bottom, preventing impurities from accumulating at the bottom of the device and ensuring the cleaning effect and long-term stable operation of the device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a sewage filtration device with a self-cleaning filter structure, comprising:

[0023] Sewage tank 1;

[0024] The filter mechanism 2 is located on the sewage tank 1. The filter mechanism 2 includes a filter cylinder 201 and a rotating component. The filter cylinder 201 is rotatably embedded in the top of the outer wall of the sewage tank 1, and the rotating component is located on the sewage tank 1.

[0025] The cleaning mechanism 3 is located on the sewage tank 1. The cleaning mechanism 3 includes a conveying cylinder 301, a conveying component, two brush rods 302 and a rinsing component. The conveying cylinder 301 is movably inserted through the top of the outer wall of the filter cylinder 201. The conveying component is located on the conveying cylinder 301. Each brush rod 302 is fixedly installed on both sides of the outer wall of the conveying cylinder 301. The rinsing component is located on the sewage tank 1.

[0026] In this implementation scheme: the sewage cylinder 1 is used to hold the sewage to be filtered, providing space for the filtration mechanism 2 and the cleaning mechanism 3. The rotating component in the filtration mechanism 2 drives the filter cylinder 201 to rotate, improving the filtration effect. When the sewage passes through the filter cylinder 201, the impurities are trapped on the surface of the filter cylinder 201, achieving preliminary filtration. The conveying cylinder 301 and conveying component in the cleaning mechanism 3 are used to transport the impurities cleaned from the filter cylinder 201. During the rotation of the filter cylinder 201, the brush on the brush rod 302 can contact the surface of the filter cylinder 201, brushing off the impurities attached to the filter cylinder 201, achieving preliminary cleaning of the filter cylinder 201. The rinsing component can rinse the surface of the filter cylinder 201 to further remove residual impurities.

[0027] Specifically, the rotating components include a forward and reverse motor 202, a pinion 203, and a large gear 204. The forward and reverse motor 202 is bolted to the top of the outer wall of the sewage cylinder 1. The pinion 203 is fixedly installed at the output end of the forward and reverse motor 202. The large gear 204 is fixedly sleeved on the outer wall of the filter cylinder 201, and the large gear 204 meshes with the pinion 203.

[0028] In this embodiment: the forward and reverse motor 202 provides rotational power as the power source. When the forward and reverse motor 202 is working, it drives the large gear 204 to rotate through the small gear 203, thereby causing the filter cylinder 201 to rotate. The rotation of the filter cylinder 201 can make the sewage pass through the mesh on the filter cylinder 201 more evenly during the filtration process, thereby improving the filtration effect. During the cleaning process, the rotating filter cylinder 201 can enable the cleaning mechanism 3 to clean the surface of the filter cylinder 201 more thoroughly.

[0029] Specifically, the conveying component includes a protective frame 303, a servo motor 304, a rotating shaft 305, and a spiral blade 306. The protective frame 303 is fixedly installed on the top of the outer wall of the sewage cylinder 1, the conveying cylinder 301 is fixedly embedded in the top of the outer wall of the protective frame 303, the servo motor 304 is installed on the top of the outer wall of the conveying cylinder 301 by bolts, the rotating shaft 305 is fixedly installed at the output end of the servo motor 304, and the spiral blade 306 is fixedly installed on the outer wall of the rotating shaft 305, and the spiral blade 306 is located on the inner wall of the conveying cylinder 301.

[0030] In this embodiment: the protective frame 303 wraps around the outer wall of the small gear 203 and the large gear 204 to protect them. When the servo motor 304 is working, it drives the rotating shaft 305 and the spiral blade 306 to rotate. The spiral blade 306 can transport the impurities in the conveying cylinder 301 upwards and finally discharge them out of the device through the discharge pipe 4. The power of the forward and reverse motor 202 and the servo motor 304 comes from an external power source and should be electrically connected to the external power source. The internal circuit principle and structure are common knowledge to those skilled in the art and will not be described in detail here. The model can be selected according to the actual use.

[0031] Specifically, the flushing components include a movable frame 307, a high-pressure flushing pipe 308, and two sets of movable components. The movable frame 307 is located between each set of movable components, the high-pressure flushing pipe 308 is installed on the bottom of the outer wall of the movable frame 307, and each set of movable components is located on the sewage tank 1.

[0032] In this embodiment, one end of the high-pressure flushing pipe 308 is movably inserted through one side of the outer wall of the sewage cylinder 1, and the high-pressure flushing pipe 308 is connected to an external water source. The high-pressure flushing pipe 308 can spray high-pressure water to flush the surface of the filter cylinder 201 and further remove residual impurities. By driving the moving frame 307 to move up and down through each set of moving components, the high-pressure flushing pipe 308 can thoroughly flush the outer wall of the filter cylinder 201.

[0033] Specifically, each set of moving components includes a threaded rod 309, a spur gear 310, and a U-shaped frame 311. The threaded rod 309 is rotatably embedded in the top of the outer wall of the sewage tank 1. The spur gear 310 is fixedly sleeved on the outer wall of the threaded rod 309, and the spur gear 310 meshes with the large gear 204. The U-shaped frame 311 is threadedly connected to the outer wall of the threaded rod 309, and the U-shaped frame 311 slides through the top of the outer wall of the sewage tank 1. The moving frame 307 is fixedly set at the bottom of the outer wall of the U-shaped frame 311.

[0034] In this embodiment: when the filter cylinder 201 rotates, the large gear 204 drives the spur gear 310 to rotate, which in turn causes the threaded rod 309 to rotate. The rotation of the threaded rod 309 drives the U-shaped frame 311 and the moving frame 307 to move axially along the threaded rod 309, thereby enabling the high-pressure flushing pipe 308 to move axially along the filter cylinder 201, achieving a comprehensive flushing of the surface of the filter cylinder 201. By meshing the spur gear 310 with the large gear 204, the rotational power of the filter cylinder 201 is directly used for driving, eliminating the need for an additional drive device, simplifying the structure, and reducing costs and energy consumption.

[0035] Specifically, a waste discharge pipe 4 is fixedly installed on the outer wall of the conveying cylinder 301 near the top edge.

[0036] In this embodiment, the impurities conveyed by the conveying component are discharged outside the device through the discharge pipe 4, keeping the inside of the device clean.

[0037] In use, the forward and reverse motor 202 is started, which drives the large gear 204 through the small gear 203, causing the filter cylinder 201 to rotate slowly in both directions. The stationary brush rod 302 moves relative to the inner wall of the rotating filter cylinder 201, scraping off the impurities attached to it. The scraped impurities settle to the bottom of the filter cylinder 201 under gravity and fall into the bottom opening of the conveying cylinder 301. The servo motor 304 is then started, driving the rotating shaft 305 and the spiral blade 306 to rotate. The spiral blade 306 continuously pushes the impurities that have fallen to the bottom of the conveying cylinder 301 upwards. Finally, the impurities are automatically collected and discharged through the discharge pipe 4. While the filter cylinder 201 rotates, the spherical gear 310 meshing with the large gear 204 rotates accordingly, driving the threaded rod 309 to rotate. The U-shaped frame 311, which is threaded to the threaded rod 309, drives the moving frame 307 and the high-pressure flushing pipe 308 to move at a constant speed along the axial direction of the filter cylinder 201. The high-pressure flushing pipe 308 is connected to an external high-pressure water source, and the sprayed water flow performs a scanning flushing on the outer wall of the filter cylinder 201, washing away fine particles that may clog the filter screen from the outside, complementing the internal brush cleaning.

[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
