Abstract
The utility model discloses a full-automatic dead-weight backwash filter, which comprises a filtering body. A filter element is arranged in the filtering body; a water inlet pipeline and a water outlet pipeline of the filtering body are simultaneously connected onto a main pipeline; the filtering body is further provided with a cleaning device and a control device; the cleaning device comprises an electric device and a cleaning brush arranged in the filtering body; the control device comprises a pressure gauge and a pressure difference sensor which are arranged at a water inlet and a water outlet of the filtering body; and the electric device, the pressure gauge and the pressure difference sensor are connected onto a PLC (programmable logic controller) by lines. The full-automatic dead-weight backwash filter is simple in structure and small in floor area; the functions of continuous filtration and automatic backwash sewage discharge can be achieved simultaneously; and the running use cost of water purifying equipment is decreased.
Description
Technical field
The utility model relates to technical field of waste water processing, is specifically related to a kind of full automatic self pressure backwash filter.
Background technology
At present, in general filter, along with the continuation of filter process, the solid phase impurity in the liquid is trapped in filter element surface, causes that increase falls in pressure, and filtration resistance increases, and filter efficiency descends.At this moment generally need to interrupt filter operation, replacing filter element or taking-up are cleaned, and be not only time-consuming but also bothersome, influences treatment effeciency.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of full automatic self pressure backwash filter is provided.
The full automatic self pressure backwash filter that the utility model provides comprises filtering bodies, is provided with filter core in the filtering bodies, and the inlet channel of filtering bodies and outlet conduit are connected on the trunk line simultaneously; Also be provided with cleaning device and control device on the said filtering bodies; Said cleaning device comprises electric device and is arranged on the cleaning brush in the filtering bodies; Said control device comprises Pressure gauge and the differential pressure pickup that is arranged on filtering bodies intake-outlet place, and said electric device, Pressure gauge and differential pressure pickup are connected on the PLC controller through circuit.
The utility model is simple in structure, floor space is little, can realize the function of continuous filtration, automatic backwash blowdown simultaneously, has reduced purifier operation use cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is further specified.Should be understood that following examples only are used to the utility model is described but not the scope that is used to limit the utility model.
Referring to Fig. 1, the full automatic self pressure backwash filter that the utility model provides comprises filtering bodies 1, is provided with filter core in the filtering bodies 1, and the inlet channel 2 of filtering bodies 1 and outlet conduit 3 are connected on the trunk line 4 simultaneously; Also be provided with cleaning device and control device on the said filtering bodies 1; Said cleaning device comprises electric device 5 and is arranged on the cleaning brush 6 in the filtering bodies 1; Said control device comprises the Pressure gauge 7 and differential pressure pickup 8 that is arranged on filtering bodies 1 intake-outlet place, and said electric device 5, Pressure gauge 7 and differential pressure pickup 8 are connected on the PLC controller 9 through circuit.
During use,
Sewage advances from inlet channel 2, through the filter element filtering in the filtering bodies 1, is gone out by outlet conduit 3.When the cartridge surface dirt is stifled, through the Pressure gauge 7 and the differential pressure pickup 8 that are installed in import and export signal is passed to PLC controller 9, start cleaning device, cleaning device is made up of electric device 5 and cleaning brush 6, and the waste water after the cleaning is discharged by sewage draining exit.Also have a kind of cleaning setting means, promptly move certain hour after, no matter whether pressure reduction reach setting value, cleaning device all starts.
