Abstract
The utility model relates to a pressure type automatic counter flushing filter apparatus, characterized in that on the basis of a gravity type automatic counter flushing filter, a respiratory valve and a water power control box with a pressure control switch are additionally provided, which results in that raw water is not needed to be pressed for lifting to supply purified water to users after the raw water is filtered by the utility model, and the water can be directly supplied according to the requirements for water pressure of the users. The utility model with novel structure and small ground occupation is the filter apparatus which needs the lowest construction investment and the lowest transporting cost in the domestic water processing and filtering technical field at present.
Description
The utility model relates to a kind of water filtering device, especially a kind of pressure type automatic back-flushing filtering device.
Present both at home and abroad gravity filter is that water purification after filtering must pressurize again and could supply with user's use, makes troubles to the user like this.
The purpose of this utility model is to provide a kind of filter with automatic fitration and automatic water-supply for people.
The technical solution of the utility model is to reequip on gravity type recoils filter automatically, dividing plate is established on housing top at filter, water inlet pipe, the center water pipe, the upper end of backwash water pipe closely cooperates and passes dividing plate, on dividing plate, be fixed with a waterpower control cabinet that has a pressure control switch, be fixed with at the top of shell two groups of lever one ends of two groups of levers respectively be located at the center water pipe and be connected with water intaking valve with blowoff valve in the water inlet pipe, the other end is connected with balanced reservoir, balanced reservoir is connected with communicating pipe with the waterpower gauge tap, fix a breather valve on dividing plate, dividing plate is passed at the breather valve top.
Fig. 1: be structure chart of the present utility model
Fig. 2: for the utility model is inhaled the structure chart of exhaling valve,
Fig. 3: be pressure control switch structure chart of the present utility model.
Set forth most preferred embodiment of the present utility model below in conjunction with accompanying drawing.As shown in the figure, by shell (12), various water pipes, water intaking valve (18), blowoff valve (20) is gone up water distributing plate (19), following water distributing plate (8), dividing plate (15) is formed filter, be provided with dividing plate (15) on the top of shell (12) and form a cavity, water inlet pipe (14), center water pipe (17), the upper end of overflow pipe (5) closely cooperates respectively and passes dividing plate (15), on dividing plate (15), fix a waterpower control cabinet (16), waterpower control cabinet (16) connects center water pipe (17), its top is connected to and is communicated with water pipe (2), be fixed with lever (1) and lever (13) at the top of shell (12), lever (13) one ends are connected with the water intaking valve that places water inlet pipe (14) (18), balanced reservoir (3) was connected with communicating pipe (2), blowoff valve (20) in lever (1) one end and the centering water pipe (17) is connected, one end of lever (13) is connected with the water intaking valve that places water inlet pipe (14) (18), balanced reservoir (3) place dividing plate (15) and overflow pipe (5) directly over, balanced reservoir (3) is communicated with waterpower control cabinet (16) by being communicated with water pipe (2), the other end of lever (1) and lever (13) is connected with balanced reservoir (3), balanced reservoir is connected with communicating pipe with the waterpower gauge tap, dividing plate (15) is run through at last fixedly this breather valve of breather valve (4) (4) top of dividing plate (15), the casing of waterpower control cabinet (16) can be made cube or cylinder, the structure of pressure switch is that the lower shoe of cylindrical shell (21) is porous plate (22), cylindrical shell (21) sidewall on porous plate (22) top is provided with some apertures (26) and is equipped with the piston (23) that links spring (24) in cylindrical shell (21), the top of cylindrical shell is equipped with a screw rod (25), pass through adjusting screw(rod), setting pressure that can the controlled pressure gauge tap, the structure of breather valve (4) is that housing (27) is shaped as up-small and down-big, lower bottom part is provided with some apertures (29), the top is provided with some passages (11), housing (27) bottom is built-in with a ball float (28), former water enters center water pipe (17) through water inlet pipe (14) during operation, the cowling panel (10) of flowing through, carry out filter just after water distributing plate (8) filters again, when the filtered water rising reaches predetermined water level, suction exhales valve (4) to close automatically, filter is in work under the pressure state, the water purification water level continues to rise to setting and just can be supplied water to the user by delivery port (6), it is the hydraulic pressure of setting that pressure is arranged in the device, along with the carrying out of filtering, the resistance of filtrate increases, the hydraulic pressure of waterpower control cabinet (16) lining also increases, when pressure increases to predetermined value, spring in the pressure control switch (24) and piston (23), be compressed, current enter porous plate (22), and by hole (26), make communicating pipe 2 with the water drainage to balanced reservoir (3), when the water yield reached predetermined value in the tandem-driving bogie, tandem-driving bogie is landing automatically just.And by lever (1) and lever (13) drive water intaking valve (18) and blowoff valve (20) work, this moment, blowoff valve was opened automatically, carry out backwash, the effluent stream of backwash enters water distributor through cowling panel (10) and excretes through sewage draining exit (9), this moment, the central tube water inlet was closed, former water is cut off, automatic backwash system (7) is opened, the drowning plate of balanced reservoir (3) is opened, water enters sewage draining exit through the pipe (5) that overflows and discharges, and along with the decline of backwash water level, the ball float (28) in the breather valve (4) also descends with water level, blocked passage (11) is opened, and filter is in the normal pressure duty.Carrying out along with backwash work, water level in the device progressively descends, balanced reservoir (3) weight saving, blowoff valve (20) and water intaking valve (18) are by deadweight landing synchronously automatically, balanced reservoir is raised under the effect of lever (1) and (13), pressure control switch in the hydraulic pressure control cabinet (16) is closed under the effect of spring simultaneously, the water inlet of water inlet center water pipe is opened again automatically, the recoil hose nozzle is closed automatically, former water is admitted to again and filters, the work that whole filter goes round and begins again.
The utlity model has the function of pressure filtration and automatic backwash, simple in structure, capital construction investment economizes, and running expense is low, the little and pressure of supply water of volume and all can regulate for water turbidity.
