[utility model content]
The purpose of this utility model will develop a kind of reverse cleaning exactly and forward filter can carry out non-interfering shunt filtering device simultaneously; Simplify the changing method of water stream channel; Simplify the structure of pipe-line system.The used press water of backwash should adopt the water purification after the filtration as far as possible, the water quality that promptly meets the filtering accuracy requirement, in order to avoid filter opening is stopped up by the large scale foreign material from opposite direction when backwash, then, these foreign material can be carried secretly again among the water purification current when forward filter, thus the filtering accuracy of influence output water purification.
The purpose of this utility model is to realize like this, it is characterized in that: two structures are identical, the simplest shunt filtering device of frame mode gives parallel connection, be they import, outlet, sewage draining exit each link, form common import, outlet and sewage draining exit, and in inlet passage, every limit path is provided with a control valve, the filter on control both sides.During work, only need opening of valves on one side, the another side valve cuts out, then this side device of opening of valves is to be in the duty that shunt filtering is carried water purification, and the there device that valve cuts out is the duty that is in back flush, by the automatically switch switching of two valves of water purification conveying situation, then the duty of both sides filter is just changed then.
The utility model can adapt to long-time cycle, even accomplish that few maintenance is non-maintaining, the inefficacy of device only limits to material corrosion and press water erosive wear, if selection is suitable, very long working life will be arranged.The filtering accuracy scope is 1.5-5mm.
The main member of the utility model parallel filtering device has three kinds promptly: the person in charge, inner filtration cover and distributary base.Their respectively UNICOM's imports, outlet and sewage draining exit, other be all elbow, threeway, concentric reducer, etc. simple pipe fitting, and all be fixture.Whole apparatus structure is simple, good manufacturability.Three mouthfuls of parts in parallel have two places to adopt flexible the connection, are convenient to assembling, and adopt reinforced pole at the port of export of shunting means, in order to avoid cause the both sides piping displacement because of water flow pressure.
