Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of backwash filter.
Background technology
Existing liquid filter is made up of Rose Box and filter core two parts, also be provided with charging aperture and discharging opening on the Rose Box, in normal operation, liquid filters through high performance filter core, when the filter element surface filter cake is piled up gradually, the filter element effective filtration area is reduced, 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.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model provides a kind of backwash filter that filter core is cleaned be convenient to.
The technical scheme that realizes the utility model purpose is as follows:
Backwash filter, be provided with filter core in the Rose Box, Rose Box is provided with the backwash liquor bleed valve that is positioned at the filter core both sides and is filtered the liquid bleed valve, end near the backwash liquor bleed valve on the Rose Box is provided with liquid injection port, the liquid injection port of Rose Box connects first liquid outlet of a backwash controller by pipeline, second liquid outlet of this backwash controller is connected with the injection apparatus that is positioned at the casing other end by the backwash pipeline, and the backwash pipeline is provided with booster.
Described backwash controller comprises ball valve body, described first liquid outlet and second liquid outlet lay respectively on this ball valve body, be provided with rotating spherical valve core in the ball valve body, Kong Yuyi the rotary handle that ball valve body top is passed on the top of spherical valve core connects, and spherical valve core is provided with liquid supplying passage.
Described backwash controller comprises three-way pipe and two control valves, described first liquid outlet and second liquid outlet lay respectively on this three-way pipe, one of them control valve is connected in the upstream section of first liquid outlet on the three-way pipe, and another control valve is connected in the upstream section of second liquid outlet on the three-way pipe.
Described control valve is an one-way control valve.
Adopted such scheme, the liquid injection port of Rose Box connects first liquid outlet of a backwash controller by pipeline, second liquid outlet of this backwash controller is connected with the injection apparatus that is positioned at the casing other end by the backwash pipeline, when needs filter materials such as sewage, close second liquid outlet of backwash controller, make first liquid outlet output of sewage backwash controller, sewage enters into Rose Box and filters by filter core.When needs clean filter core, close first liquid outlet of backwash controller, make cleaning fluid from the output of second liquid outlet of backwash controller, by the booster on the backwash pipeline to clean pressurize clearly after, be sprayed onto on the filter core with injection apparatus, filter core is cleaned.
