Abstract
A self-cleaning filter is provided by the utility model, which comprises an electric device, a cover board, an enclosure, an intake pipe, an outlet pipe, a filtering cartridge, a transmission shaft, an upper carrier plate, a lower carrier plate and a sealing plate. The electric device is equipped on the cover board, which is connected with the enclosure through bolts. The intake pipe and the outlet pipe are equipped on the enclosure. Center lines of the inlet pipe and the outlet pipe, and that of the enclosure are in the same plane. The filtering cartridge is equipped in the enclosure and supported by the upper carrier plate and the lower carrier plate. The sealing plate is equipped on the filtering cartridge; a differential pressure switch is also equipped on one side of the cover board, and is connected with a piezometer on the intake pipe and one on the outlet pipe respectively. Good effects of the utility model are automatically controlled by using inlet and outlet differential water pressure with large filtration area, small drag loss and good self-cleaning effect.
Description
Affiliated technical field
The utility model relates to a kind of filter, specifically a kind of filter with self-cleaning function.
Background technology
The major part of the water filter that present domestic metallurgy industry uses still is the outmoded chain type filter plant of structure, in order to make the industrial flow continuous water supply, need that two cover water filters in parallel reach into and out of water valve between water inlet pipe and outlet pipe, after between a filter work timing, when flow being narrowed down to satisfy working condition requirement because of the accumulation of foul in the filter cylinder, need hand sweeping is carried out in this filter cut-out, another filter that has cleaned puts into operation.There is the equipment heaviness in this chain type filter, and investment is big, and installing space is big, manually switches, cleans, the deficiency that labour intensity is big.
Summary of the invention
In order to overcome existing filter apparatus heaviness, investment is big, and installing space is big, the deficiency that manually clean, labour intensity is big, and it is a kind of from washing filter that the utility model provides.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of self-cleaning filter, comprise electric device, cover plate, housing, water inlet pipe, outlet pipe, filter cylinder, power transmission shaft, upper bearing plate, lower support plate, sealing plate, electric device is installed on the cover board, cover plate and housing pass through Bolt Connection, water inlet pipe and water outlet short tube are arranged on the housing, advance, the center line of outlet pipe and housing center line are in same plane, filter cylinder is installed in the housing, by upper bearing plate and lower supporting plates supports, sealing plate is equipped with in the filter cylinder top, cover plate one side also is equipped with differential pressure pickup, links to each other with pressure-measuring pipe on the outlet pipe with water inlet pipe respectively.
The beneficial effects of the utility model are to utilize Inlet and outlet water pressure reduction to control automatically, and filter area is big, and drag losses is little, and self-cleaning is effective.
Description of drawings
Fig. 1 is the sectional structural map of embodiment
Among the figure: 1. electric device; 2. differential pressure pickup; 3. cover plate; 4. housing; 5. water inlet pipe; 6. power transmission shaft; 7. sealing plate; 8. upper bearing plate; 9. outlet pipe; 10. pressure-measuring pipe; 11. filter cylinder; 12. lower support plate; 13. sewage draining exit.
The specific embodiment
As shown in Figure 1, a kind of self-cleaning filter, comprise electric device 1, cover plate 3, housing 4, water inlet pipe 5, outlet pipe 9, filter cylinder 11, power transmission shaft 6, upper bearing plate 8, lower support plate 12, sealing plate 7, electric device 1 is installed on the cover plate 3, cover plate 3 passes through Bolt Connection with housing 4, water inlet pipe 5 and outlet pipe 9 are arranged on the housing 4, water inlet pipe 5, the center line of outlet pipe 9 and housing 4 center lines are in same plane, filter cylinder 11 is installed in housing interior 4, by upper bearing plate 8 and lower support plate 12 supportings, sealing plate 7 is equipped with in filter cylinder top, and cover plate 3 one sides also are equipped with differential pressure pickup 2, respectively with water inlet pipe 5, pressure-measuring pipe 10 on the outlet pipe 9 links to each other; Filter cylinder 11 has 4, is symmetrically distributed along the housing center line, and 2 filtrations, 2 self-cleanings rely on sealing plate 7 to switch.When self-cleaning filter is in the work running status, water to be filtered from the trunk line upstream extremity, enter 2 filter cylinder 11 inboards of filter (2 filter cylinders then are in the self-cleaning state and treat the operation state in addition) filtration laterally by water inlet pipe 5 and enter outlet pipe 9, impurity in the water just is trapped within the inboard of filter cylinder at this moment, and the water after the filter enters the trunk line downstream and flows into industrial flow by outlet pipe 9.Continuous filtration is in service, impurity in the water is constantly held back by filter cylinder 11, thereby the pressure reduction at filter inlet tube and outlet tube two ends is constantly risen, a certain when presetting pressure difference when rising to, electric device 1 starts, thereby the sealing plate 7 that drives power transmission shaft 6 and be fixed on the power transmission shaft 6 rotates, and carries out the switching of filter cylinder 11, and dirt is then discharged by sewage draining exit 13.
