Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome above-mentioned prior art, a kind of forward type backwash filter is provided, this forward type backwash filter can ensure just conventional water, without the need to dismantling filter during the impurity such as gravel, iron rust in cleaning filter screen, adopts the principle switching water (flow) direction back-flushing, back-flushings such as the gravel be blocked in filter screen, impurity, pour sewage draining exit, realize cleaning filter screen impurity, easy to operate, structure is simple, and cleaning blocking impurity is clean.
The utility model solves the technical scheme that its technical problem adopts: a kind of forward type backwash filter, comprise filter body, with the sleeve coordinated is installed bottom filter body, with filter body top, the lid coordinated is installed, to be placed in filter body and sleeve and to protrude the control lever of lid, to be connected with control lever and rotatable control lever realizes the handwheel of control lever pull lift action, to be placed in filter body and sleeve and to entangle the filter screen of control lever, sleeve bottom is provided with movablely with control lever installs the joint be connected, joint is connected and installed with hose coupling, described filter body and sleeve form the structure with water channel, filter body both sides are respectively equipped with the running water water inlet and filtered water delivery port that communicate with water channel, form water channel by recoil inlet opening between filter body with sleeve to communicate, control lever top is provided with the control lever running water inlet opening communicated with the water channel of running water water inlet, control lever middle and upper part be provided with to be positioned at below control lever running water inlet opening and can clog recoil inlet opening water sealing plug, control lever bottom is provided with the control lever running water outlet hole be positioned at below water sealing plug, filtered water delivery port communicates with the water channel of sleeve.
The operation principle of this forward type backwash filter is: during normal use water outlet, water enters from running water water inlet, now water sealing plug can close recoil inlet opening, make water can not enter from recoil inlet opening, then control lever running water inlet opening is entered, flow out and net filtration after filtration from control lever running water outlet hole, through the water outlet of filtered water delivery port after filtration, and the port that now bottom of control lever also clogs joint makes water can not flow out from joint; When needs carry out backwash, to outward winding counterclockwise handwheel, drive the lift of control lever, water sealing plug no longer closes recoil inlet opening, control lever running water inlet opening is also sealed and is not communicated with the water channel of filter body, the bottom of control lever and joint are formed and depart from, water enters from running water water inlet, sleeve is entered through recoil inlet opening, rinse from the outer wall of screen pack to the inwall of filter screen, impurity such as being jammed in the gravel of its interior and iron rust is washed open, and gravel and iron rust etc. to fall in joint and wash away, and complete backwash.After flushing, use when need normally make, only need be tight handwheel dextrorotation, makes control lever etc. reset and can normally use.
Further, described running water water inlet and filtered water delivery port are provided with nut block, be provided with an O type circle water-tight, be provided with the 2nd O RunddichtringO water-tight between filter body and sleeve between lid and filter body.
In sum, forward type backwash filter of the present utility model can ensure just conventional water, cleaning filter screen in the impurity such as gravel, iron rust time without the need to dismantling filter, adopt the principle switching water (flow) direction back-flushing, back-flushings such as the gravel be blocked in filter screen, impurity, pour sewage draining exit, realize cleaning filter screen impurity, easy to operate, structure is simple, and cleaning blocking impurity is clean.
