Description
Technical Field
The invention belongs to the technical field of purifying devices, and particularly relates to a self-cleaning filter.
Background
In the filtration and purification of sewage, a filter element is required to be used for cleaning solid particles in the sewage. Most of the currently used filter elements are adhered with more impurities on the surface after working for a period of time, so that the purification effect is affected, and the filter elements are usually replaced regularly to ensure the quality of filtration and purification. Although a filter for removing impurities on the surface of the filter element in a back flushing mode appears in the market, the back flushing period is short, the back flushing frequency is high, the cleaning effect is not ideal, and the filter element needs to be replaced after the time is long.
Disclosure of Invention

The self-cleaning filter comprises a shell, wherein a drain pipe and a first water inlet pipe are arranged on the shell, the drain pipe is positioned at the bottom of the shell, a filter core sleeve and a filter core are arranged in the shell, the lower end of the filter core sleeve is connected with the drain pipe, a plurality of inclined holes are uniformly distributed on the side wall of the filter core sleeve, the filter core is positioned in the filter core sleeve, a filter core seat is arranged at the lower end of the filter core, a water outlet is arranged on the filter core seat, and the lower end of the filter core seat extends out of the filter core sleeve and is fixed at the bottom of the shell.
The invention is also characterized in that:
the plurality of inclined holes incline towards the same direction.
The inclined holes are arranged in parallel in a plurality of rows, and the inclined holes on two adjacent rows are distributed in a staggered manner.
The top of the shell is provided with a water inlet which is communicated with the filter element sleeve.
The upper end of the shell is provided with a pressing ring, and the upper end of the filter element stretches into the water inlet and is propped against the lower end of the pressing ring.
Sealing gaskets are arranged between the pressing ring and the shell and between the filter element and the filter element seat.
Still include the second inlet tube, first inlet tube with the second inlet tube all sets up the bottom of shell.
The water inlet end of the first water inlet pipe and the water inlet end of the second water inlet pipe are both provided with filter screens.
The beneficial effects of the invention are as follows: when the self-cleaning filter is used for purifying sewage, the sewage is injected into the filter element in a cyclone mode under the guide effect of the inclined holes on the side wall of the filter element sleeve, and solid particles in the sewage can be washed away under the cyclone effect of the sewage even if the solid particles are attached to the surface of the filter element, so that the filtering effect of the filter element is not influenced, and the filter element is not required to be replaced frequently.
Drawings
FIG. 1 is a schematic view of the self-cleaning filter according to the present invention.
In the figure, a filter element 1, a shell 2, a sealing gasket 3, a pressing ring 4, a screw 5, an inclined hole 6, a filter element sleeve 7, a blow-off pipe 8, a first water inlet pipe 9, a second water inlet pipe 10 and a filter element seat 11.
Detailed Description
The invention will be described in detail below with reference to the drawings and the detailed description.
The self-cleaning filter disclosed by the invention, as shown in fig. 1, comprises a shell 2, wherein a drain pipe 8 and a first water inlet pipe 9 are arranged on the shell 2, the drain pipe 8 is positioned at the bottom of the shell 2, a filter element sleeve 7 and a filter element 1 are arranged in the shell 2, the lower end of the filter element sleeve 7 is communicated with the drain pipe 8, a plurality of inclined holes 6 are uniformly distributed on the side wall of the filter element sleeve 7, the filter element 1 is positioned in the filter element sleeve 7, a filter element seat 11 is arranged at the lower end of the filter element 1, a water outlet is arranged on the filter element seat 11, and the lower end of the filter element seat 11 extends out of the filter element sleeve 7 and is fixed at the bottom of the shell 2.
When the self-cleaning filter is in a cleaning work, the drain pipe 8 is always in a closed state, sewage firstly enters the shell 1 from the first water inlet pipe 9, then is emitted to the filter element 1 in a cyclone mode under the guide effect of the inclined hole 6 on the outer wall of the filter element sleeve 7, the cyclone-sprayed sewage can generate erosion force on solid particles attached to the surface of the filter element 1, at the moment, the solid particles can be timely washed away by the sewage under the erosion force, and the solid particles cannot remain on the surface of the filter element 1, so that the filtering effect of the filter element is not influenced.
After the solid particles are filtered by the filter element 1, the solid particles can be precipitated at the bottom of the filter element sleeve 7, and after the self-cleaning filter is cleaned for a period of time, a worker can periodically open the drain pipe 8, so that the filtered solid particles are discharged from the drain pipe 8.
As shown in fig. 1, the plurality of inclined holes 6 are inclined in the same direction.
All inclined holes 6 are inclined in the same direction, so that the sewage ejected from the inclined holes 6 can be guaranteed to swirl in the same direction, mutual interference can be avoided, and the erosion force can be maximized.
As shown in fig. 1, the plurality of inclined holes 6 are arranged in parallel in a plurality of rows, and the inclined holes 6 on two adjacent rows are staggered.
The inclined holes 6 on two adjacent rows are distributed in a staggered manner on the rotating track, so that the surfaces of the filter element 1 can be guaranteed to be all subjected to the effect of erosion, and the dead zone, which cannot be covered by the erosion, of solid particles in sewage is eliminated.
As shown in fig. 1, the top of the housing 2 is provided with a water inlet which communicates with the cartridge housing 7.
After the self-cleaning filter is cleaned for a period of time, a worker can periodically heighten the pressure water to the water inlet, and backwash the filter element sleeve 7 through the high pressure water, so that solid particles in the self-cleaning filter are discharged from the sewage pipe 8.
As shown in fig. 1, the pressing ring 4 is fixed at the upper end of the casing 2 through the screw 5, the filter element 1 is arranged in the filter element sleeve 7, the upper end of the filter element extends into the water inlet and is propped against the lower end of the pressing ring 4, the lower end of the filter element is fixed at the bottom of the casing 2 through the filter element seat 11, and the filter element is good in stability and convenient to detach and maintain during working.
As shown in figure 1, the gap between the pressing ring 4 and the shell 2 and the gap between the filter element 1 and the filter element seat 11 are sealed by a sealing gasket 3, and sewage can be prevented from flowing out from the gap between the pressing ring 4 and the shell 2 after the water inlet is closed.
As shown in fig. 1, the water inlet device further comprises a second water inlet pipe 10, and the first water inlet pipe 9 and the second water inlet pipe 10 are arranged at the bottom of the shell 2.
In operation, a worker can not only feed water through the first water inlet pipe 9 and the second water inlet pipe 10 at the same time, but also feed water through the first water inlet pipe 9 or the second water inlet pipe 10 independently. When the first water inlet pipe 9 and the second water inlet pipe 10 are simultaneously fed, the rotational flow speed of sewage is maximum, so that the erosion force on the surface of the filter element 1 is also maximum.
As shown in fig. 1, the water inlet ends of the first water inlet pipe 9 and the second water inlet pipe 10 are respectively provided with a filter screen.
The filter screen is arranged at the water inlet end of the first water inlet pipe 9 and the water inlet end of the second water inlet pipe 10, so that larger impurities in sewage can be preliminarily filtered, the workload of the filter element is reduced, and the service life of the self-cleaning filter is prolonged.
The self-cleaning filter solves the problem that the filter core needs to be replaced frequently when the existing filter is used for filtering and purifying.
