Abstract
The utility model relates to a fluid filter which adopts the gas automatic flush back, and is suitable for the solid-liquid filter. Wherein, a filter 6 is composed of two parts of a filter body and a top cover. A filtering core 8 is arranged in the filter body, and a feed opening 12 and a discharge opening 14 are also arranged on the filter body. The bottom of the filter body is provided with a drainage opening which is connected with a dirt storing tank 11, and the upper part of the filter body is provided with an exhaust valve 2. The utility model is characterized in that an air inlet 13 which is connected with an air storage tank 10 through an inlet valve 3 is arranged on the upper part of the filter 6. The utility model has the advantages that the structure is simple; the filtering core is rapidly cleaned in the filter, and is not need to be taken out; the operation is easy; the efficiency is high; etc.
Description
Technical field
The utility model relates to a kind of liquid filter that is applicable to the employing gas automatic backwash that solid-liquid filters.
Background technology
Existing solid-liquid filter is made up of filter body and loam cake two parts, is provided with filter core in body, also is provided with charging aperture and discharging opening on the body, and the bottom of body has sewage draining exit to be connected with filth storage can, and air bleeding valve is arranged at top.In normal operation, liquid filters through high performance filter core, piles up gradually when the filter element surface filter cake, and the filter element effective filtration area is reduced, and when influencing filter efficiency, must clear up the filter core of filter; Common method for cleaning is, filter is opened, and takes out filter core, clears up, exist time-consuming, the deficiency that efficient is lower.
Technical scheme
At above-mentioned the deficiencies in the prior art, the purpose of this utility model is a kind of gas backwash filter of design, need not filter core is taken out, and in filter filter core is carried out Rapid Cleaning, and is easy and simple to handle.
The technical scheme that realizes above-mentioned purpose is, a kind of gas backwash filter, filter 6 is made up of filter body and loam cake two parts, in body, be provided with filter core 8, also be provided with charging aperture 12 and discharging opening 14 on the body, the bottom of body has sewage draining exit 15 to be connected with filth storage can 11, and air bleeding valve 2 is arranged at top, it is characterized in that: be provided with air inlet 13 in the upper end of filter 6, this air inlet is connected with air accumulator 10 by intake valve 3.
The utlity model has simple in structurely, need not filter core is taken out, in filter, filter core is carried out Rapid Cleaning, easy and simple to handle, advantages such as high efficiency.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structure of filter schematic diagrames.
Specific implementation
See also Fig. 1, Fig. 2, filter 6 is made up of filter body and loam cake two parts, is provided with filter core 8 in body, also is provided with charging aperture 12 and discharging opening 14 on the body, and charging aperture 12 is connected inlet valve 1 and bleeder valve 4 respectively with discharging opening 14; Sewage draining exit 15 is arranged at the bottom of body, and it is connected with filth storage can 11 by quck-opening valve 7; Exhaust outlet 17 and air bleeding valve 2 are arranged at top, and, being provided with air inlet 13 in the upper end of filter 6, this air inlet is connected with air accumulator 10 by intake valve 3, and air accumulator 10 also connects air pump 9.
In normal operation, liquid enters filter 6 by inlet valve 1 and charging aperture 12, filters through high performance filter core 8, then, is discharged by bleeder valve 4 and discharging opening 14; Pile up gradually when filter element surface filter cake 16, the filter element effective filtration area is reduced, when influencing filter efficiency, must clear up the filter core of filter; When cleaning, closing liquid inlet valve 1 and bleeder valve 4 are opened air bleeding valve 2, keep communicating with ambient atmosphere, open quck-opening valve 7 simultaneously, and the residual liquid in the filter 6 begins to filth storage can 11 dischargings; When liquid level drops to certain height, when reaching backwash liquid level 5, close air bleeding valve 2, open intake valve 3, gases at high pressure through air pump 9 and air accumulator 10 pressurizations enter in the filter 6, under action of air pressure, form the back flush force of explosion, the filter cake that will be deposited in cartridge surface rapidly washes.Adopt this device can be implemented in Rapid Cleaning under the covered situation of filter interior to the filter core of filter, saving of work and time can be worked filter expeditiously.
