Embodiment
With reference to Fig. 1 and Fig. 2, a specific embodiment of the present utility model is described in detail, but not to power of the present utility model
Profit requires to do any restriction.
As shown in Figure 1, a kind of Full-automatic self-cleaning filter, including drive mechanism 1, closure 2, power transmission shaft 4, blowdown
Valve 5, filter screen 6, turn brush combination 7, cylinder 8, delivery port 9, pressure difference indicator 10, water inlet 11, blow-off pipe 12.Cylinder 8 is vertically set
Put, the bottom of cylinder 8 and side are respectively arranged with water inlet 11 and delivery port 9, and closure 2 is installed on the top of cylinder 8, driving machine
Structure 1 is fixed on closure 2, and power transmission shaft 3 is connected with drive mechanism 1, and for the rotation with turn brush combination 7, blow-off pipe 12 is set
Above cylinder 8, pipe one end communicates with the top of cylinder 8, and the other end is connected with blowoff valve 5, and pressure difference indicator 10 is installed on cylinder 8
Side, its both ends are separately positioned at the water inlet 11 and delivery port 9 of cylinder, and filter screen 6 passes through located at cylinder top and end
Bolt is fixed in cylinder 8, and coaxial with power transmission shaft 4, and gap is left between filter screen 6 and the inwall of cylinder 8.Turn brush combination 7 to set
In in filter screen 6, it is made up of the cleaning brush of 2 Central Symmetries distributions, cleaning brush is fixed on power transmission shaft 3 and tight with the inwall of filter screen 6
Closely connected conjunction, wherein, cleaning brush length is the half of filter screen axial length, and cleaning brush is the scrubbing brush that edge is covered with bristle.
The course of work of the present utility model is：
Treatment sewage enters device from water inlet, by strainer filtering, suspension, particulate matter more than filter screen gap etc.
Debris is intercepted by filter screen 6 and remained on filter screen inwall, and clear liquid flows out from delivery port after filter, blowoff valve in normal filtration processing procedure
5 are closed.When filtering a period of time, the debris intercepted on filter screen 6 is gradually accumulated, and the water flow of filter screen 6 gradually subtracts
It is small, and then the pressure differential of intake antrum and water chamber is formed, detected by pressure difference indicator 10, when pressure differential reaches certain journey
When spending, pressure difference indicator 10 sends signal, and blowoff valve 4 automatically turns on, and drive mechanism 1 brings into operation, by power transmission shaft 3 with turn
Brush combination 7 rotates, and is cleared up and is excluded by blowoff valve connecting pipe 12 to remaining in the debris on filter screen inwall, works as cleaning
Finish that rear drive mechanism 1 is automatically stopped operating, blowoff valve 4 is closed automatically, returned into and out of water cavity pressure difference in normal range (NR).The mistake
Device is filtered by the repetition of above-mentioned cycle, continuous service.
