Description

A kind of horizontal high-pressure full-automatic back washing filter
Technical field
The utility model relates to filtration device structure, relates in particular to a kind of filter that can automatic backwash.
Background technology
Water conservation and using water wisely and people live closely bound up, and the recycling of water resource is particularly important.Water for industrial use, air-conditioning cooling circulating water, automobile circulating water, boiler feed water, bathing pool, well water, river, ballast water for ship etc. all need to carry out the filtration treatment of water, it is the only way which must be passed of water resource recycling, because tradition seldom adopts by the method that chemical substance is filtered, mostly adopt physical cleaning method filter, remove by mechanical filter principle the middle impurity that anhydrates.Mechanical filter is the most frequently used equipment.Traditional mechanical filter, medium completes filtration through filter opening to filter screen outside from filter screen inner chamber, in this process, Impurity deposition is in filter screen bottom or invest on filter screen inwall, and the impurity that is slightly larger than filter opening is embedded in filter opening, along with increasing of filter medium, adhere to and to embed the impurity of filter screen more and more, until stop up, change the filtration that has had a strong impact on filter screen into, must clean or change filter screen.For addressing this problem, the most original method is to take out filter core to carry out manual cleaning, and workload is large, and cleaning quality does not ensure, and filter process is discontinuous.For reducing wash number, also have the filter screen that adopts less mesh, but filtering accuracy is low, poor filtration effect.
Summary of the invention
The purpose of this utility model is to provide a kind of horizontal high-pressure full-automatic back washing filter, has thick, thin two-layer strainer filtering, and good filtration effect is difficult for stopping up filter screen; Automatically carry out cleaning operation by pressure detecting, do not need people manually to control; Overall package and dismounting are simple, long service life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of horizontal high-pressure full-automatic back washing filter, comprise inlet on the front shroud at cylindrical shell, cylindrical shell two ends and back shroud, cylinder lateral wall and liquid outlet, screen pack, described cylindrical shell horizontal positioned, front shroud is positioned near inlet end, and back shroud is positioned near liquid outlet end; Described screen pack has two, is tubular construction and is distributed in side by side in cylindrical shell, and coarse strainer is positioned at inlet end, and fie screen is positioned at liquid outlet end; Coarse strainer has vertical annular filter screen dividing plate with fie screen intersection, filter screen dividing plate is by the spatial separation between the space between coarse strainer and cylinder inboard wall and fie screen and cylinder inboard wall, prevent that the sewage not filtering through coarse strainer from entering leakage fluid dram end, coarse strainer communicates with the space of fie screen inside; Fie screen inner side is provided with soil pick-up arm, on soil pick-up arm, has pollution-absorbing nozzle, and fie screen outside is provided with cleaning arm, cleans arm and is provided with cleaning mouth; Soil pick-up arm and cleaning arm are all fixed with central rotating shaft, and central rotating shaft is hollow pipeline, is divided into blow-off line and pipe blow-through by dividing plate; Described pipe blow-through is communicated with the clear water chamber being fixed on back shroud, and there is a water inlet side, clear water chamber; Upper end, clear water chamber is transmission device, and described transmission device one end is connected with central rotating shaft, and one end is connected with reductor, and described central rotating shaft drives and cleans arm and branch sewer; Between inlet and liquid outlet, be provided with differential pressure transmitter, differential pressure transmitter is connected with control device.Turbid media enters cylindrical shell by inlet, first filter through coarse strainer, then filter through fie screen, discharge through liquid outlet, the pressure of differential pressure transmitter Real-Time Monitoring inlet and liquid outlet, in filter process, along with increasing of screen pack impurity, the inflow-rate of water turbine of screen pack reduces gradually, the pressure of liquid outlet reduces gradually, in the time that differential pressure transmitter measured value is greater than preset value, control device starts reductor, cleaning procedure is started working, high-pressure wash water is ejected to fie screen outer surface through cleaning arm from cleaning mouth by clear water chamber, the impurity on fie screen surface and sewage enter soil pick-up arm through pollution-absorbing nozzle and enter blow-off line, finally discharged by soil chamber, complete a clean cycle.Clean cycle and filter process carry out simultaneously, do not interfere with each other, and in clean cycle process, filter is being worked always.
As a kind of preferred version of horizontal high-pressure full-automatic back washing filter described in the utility model, described pollution-absorbing nozzle has many groups with cleaning mouth, the parallel screen pack both sides that are installed on, can carry out omnibearing cleaning to filter screen, the impurity washing down directly enters pollution-absorbing nozzle, discharges by blow-off line.
