The utility model overcomes the deficiency that prior art exists, technical problem to be solved be to provide a kind of simple in structure, withstand voltage good, backwash filter easy to use.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of full-automatic back washing filter, comprise shell, filter hat, the filter end, filter screen, upper butterfly valve, lower butterfly valve, pull bar, valve body, valve, blow-off pipe, upper barrier film, lower diaphragm plate, abnormity pad, dottle pin, connect spiral shell, attachment screw, fixed mount, upper end housing and lower end housing, described filter hat, the filter end, filter screen, valve body is all arranged on enclosure, and filter hat is connected in the upper end of vertical filter screen, the filter end, is connected in the lower end of vertical filter screen, outer casing inner wall in the filter side of labeling is provided with for blocking the groove of interior jump ring, lower end at the bottom of described filter is embedded in the top groove of valve body, described blow-off pipe one end and valve body are connected, the other end is connected with shell through after shell, at the outside groove that has sealing ring in embedding of described filter hat, at the bottom of described filter, outside has the groove that embeds lower seal,
The middle and upper part of described filter screen inside is fixed with mandrel and upper arresting pin in level, middle and lower part is fixed with mandrel and lower limit pin under level, the centre bore matched in clearance of described upper mandrel and described upper butterfly valve, described upper arresting pin carries out spacing to the upper butterfly valve of level, the centre bore matched in clearance of described lower mandrel and described lower butterfly valve, described lower limit pin carries out spacing to the lower butterfly valve of level, and the centre bore of the centre bore of upper butterfly valve and lower butterfly valve is offset respectively the both sides at filter screen axis, described upper butterfly valve and lower butterfly valve are hinged with one end of pull bar respectively, and pull bar is connected with the end of lower butterfly valve the same side with upper butterfly valve,
Described valve inner is disposed with valve from top to bottom, upper barrier film, dottle pin, lower diaphragm plate, at upper barrier film, dottle pin, the outer setting of lower diaphragm plate has abnormity pad, and the inwall of described abnormity pad is provided with for blocking the groove at upper barrier film and lower diaphragm plate two ends, below valve body, be also provided with fixed mount, bottom center at fixed mount is provided with jacking block, the described spiral shell that connects is successively through lower diaphragm plate, dottle pin, after upper barrier film, be threaded with valve lower end, and connecing spiral shell lower end and jacking block outside is also socketed with spring, described attachment screw is respectively successively through fixed mount, lower diaphragm plate, abnormity pad, after upper barrier film, be threaded with both sides, valve lower end,
In the junction of described shell lower end and described lower end housing, be provided with the lower catch hoop pipe joint of socket shell and lower end housing, described shell upper end and described on the junction of end housing be provided with the front band pipe joint of socket shell and lower end housing.
The center line of described shell, filter screen, valve, upper barrier film, dottle pin, lower diaphragm plate, special-shaped pad, valve body and fixed mount is on same straight line.
Described jacking block is movable, is provided with the adjusting bolt contacting with jacking block through fixed mount bottom thread hole in described fixed mount lower end.
Described filter screen is the cylinder of MULTILAYER COMPOSITE.
Compared to the prior art the utility model has following beneficial effect.
One, due to being designed to that the utility model adopts: upper butterfly valve centre bore and lower butterfly valve centre bore are offset to respectively housing axis both sides; By spring, the jacking block of fixed mount is connected with the spiral shell elasticity that connects of valve lower end, valve can be up and down at valve inner.When liquid enters after filter screen from the entrance of upper end housing, because upper butterfly valve and lower butterfly valve are the fluid pressure that a long-armed side produces and are greater than the pressure that galianconism one side produces, above butterfly valve starts to clockwise rotate around upper mandrel, go up butterfly valve and drive pull bar simultaneously, pull bar drives lower butterfly valve to start clockwise motion, now the liquid pressure of filter screen inside acts on valve, outside liquid pressure acts on the lower end of barrier film, when the pressure of filter screen inside approaches external pressure, external pressure is greater than the active force of filter screen internal liquid pressure to valve to the active force of barrier film and spring pressure sum, valve is in closure state, now go up butterfly valve and turn to gradually vertical opening, lower butterfly valve also turns to the closed condition of level simultaneously, at this moment water (flow) direction is normal duty,
Along with liquid continuous inflow filter screen, under liquid effects, butterfly valve starts to rotate counterclockwise around lower mandrel, with the pull bar of butterfly valve drive at present, pull bar drives upper butterfly valve to start counterclockwise motion, when filter screen internal pressure is greater than external pressure certain value, internal pressure is greater than external pressure to barrier film and acting force of the spring sum to the active force of valve, valve is in opening, when valve is opened, lower butterfly valve turns to vertical opening gradually, upper butterfly valve also turns to the closed condition of level simultaneously, the inside and outside formation reverse differential pressure of filter screen, liquid carries out backwash to filter screen from outside to inside and discharges through blow-off pipe, water (flow) direction is backwash state.Backwash completes, and filter screen internal pressure and external pressure reach unanimity, and the power that liquid pressure acts on valve is less than the active force sum that acts on barrier film and spring, and valve is again in closure state, and the utility model returns to normal duty;
The utility model is not only simple in structure, and processing ease, can realize easily the work of automatic backwash, is also difficult for breaking down simultaneously, even if break down, keeps in repair also easier.
Two, the utility model adopts the design of two barrier films, and barrier film and lower diaphragm plate are set below valve, and the design of this pair of barrier film has improved withstand voltage greatly, and backwash effect is good simultaneously.
Three, the jacking block of the utility model fixed mount is movable, and in fixed mount lower end, be provided with the adjusting bolt contacting with jacking block through fixed mount bottom thread hole, like this can be by the height that is screwed into, back-outs to regulate jacking block of adjusting bolt, and then coming regulating spring to dock the active force of spiral shell, it is convenient flexible that this design is used the utility model.
