Description
Technical field
Automatic backwashing filter, belongs to filter technology field.
Background technology
Existing automatic backwashing filter, a kind of filter for the foreign like product of imitation, not only lacks novelty, and it is not smart to do manual work, and withstand voltage is on the low side, and suitable environment is more single; Another kind is to realize backwash with balanced valve control magnetic valve, not only complex structure but also be only applicable to possess in the environment of power supply.
Utility model content
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: automatic backwashing filter, comprise shell, filter hat, the filter end, filter screen, upper butterfly valve, ball, pull bar, valve body, valve, blow-off pipe, barrier film, 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, be provided with the groove for blocking interior jump ring at the outer casing inner wall of the filter side of labeling, be fixed with straight tube in bottom, the filter end, the lower end of described straight tube is embedded in the top elbows 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, have the groove that embeds lower seal in described straight tube outside,
The middle and upper part of described filter screen inside is fixed with horizontal mandrel and spacer pin, middle and lower part is provided with ball, described upper butterfly valve and ball are hinged with one end of pull bar respectively, the centre bore matched in clearance of described mandrel and described upper butterfly valve, described spacer pin carries out spacing to the upper butterfly valve of level, the inwall matched in clearance of described ball and described straight tube, and the centre bore He Qiu center of upper butterfly valve is all offset the same side at filter screen axis;
Described valve inner is disposed with valve, barrier film, spring abutment from top to bottom, the lower end of described valve is threaded with spring abutment through after barrier film, below valve body, be provided with fixed mount, bottom at fixed mount is provided with jacking block, be connected to spring at described spring abutment and jacking block outer cover, described attachment screw is respectively successively through being threaded with both sides, valve lower end after fixed mount, barrier film;
Be provided with the lower catch hoop pipe joint of socket shell and lower end housing in the junction of described shell lower end and described 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, barrier film, spring abutment, 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 ball center are offset to respectively housing axis the same side; By spring, the jacking block of fixed mount is connected with the spring abutment elasticity 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 the fluid pressure that upper butterfly valve produces for a long-armed side is greater than the pressure that galianconism one side produces, above butterfly valve starts to clockwise rotate around mandrel, go up butterfly valve and drive pull bar simultaneously, pull bar drives ball to start to move downward along straight tube, now the liquid pressure of filter screen inside acts on valve, outside liquid pressure acts on the lower end of barrier film, in the time that the pressure of filter screen inside approaches external pressure, active force and the spring pressure sum of external pressure to barrier film is greater than the active force of filter screen internal liquid pressure to valve, valve is in closure state, now go up butterfly valve and turn to gradually vertical opening, ball also moves to closed condition simultaneously, at this moment water (flow) direction is normal duty,
Along with liquid continuous inflow filter screen, liquid effects ball starts to rotate along straight tube, the moving pull bar of spherical zone simultaneously, pull bar drives upper butterfly valve to start counterclockwise motion, in the time that 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, ball moves to opening, 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 uniseptate design, and one deck barrier film is set below valve, and this uniseptate design facilitates valve backhaul.
Three, the jacking block of the utility model fixed mount is movable, and be provided with the adjusting bolt contacting with jacking block through fixed mount bottom thread hole in fixed mount lower end, like this can be by the height that is screwed into, back-outs to regulate jacking block of adjusting bolt, and then carry out the active force of regulating spring docking spiral shell, this design make the utility model use convenient flexibly.
