nullThe technical solution of the utility model is: the fore filter of a kind of adjustable backwash，Including the T-shaped top shell being from top to bottom sequentially connected with、Middle seat、Shell body，Raw water inlet and water purification outlet it is provided with in described T-shaped top shell，It is provided with water-locator inside T-shaped top shell,Described shell body is internally provided with filter element，Former water flow passage is formed between filter element outer wall and shell body inwall，Filter element inner flow passage it is provided with in filter element，Described filter element top is provided with the filter element seat of honour，Filter element bottom is fixed in shell body by filter element base，The annular intake chamber being connected with former water flow passage it is provided with on the filter element seat of honour，The outlet being connected with water-locator and filter element inner flow passage it is provided with on the filter element seat of honour，It is provided with annular magnet outside annular intake chamber，Shell body lower end is provided with the waste with blowoff valve，Described former water flow passage is connected with waste.
Further, described water-locator includes that knob, knob lower end are provided with and is controlled, by knob, the water-locator outlet that connects with water purification outlet or disconnect, and knob lower end is provided with the backwash water inlet being connected with raw water inlet by knob control or disconnecting.
Further, described T-shaped top shell upper end is provided with fluting, and described knob runs through fluting, and T-shaped top shell bottom is provided with annular boss, and described middle seat is provided with draw-in groove, described annular boss and draw-in groove clamping.
Further, described fluting being provided with the sector notch that in 90 degree, described knob outer circumferential side is provided with arc boss, and arc boss is positioned at sector notch.
Further, the both end sides of described sector notch is provided with switch mark.
Further, described annular magnet is sealingly fastened in filter cartridge seat by ABS material.
Further, described filter element shape ringwise, it is divided into upper and lower two-layer, upper strata filter element and the filter element that lower floor's filter element is different composite material for water treatment.
Compared with prior art, this utility model has the advantage that
Sewage backwash is easy, it is only necessary to the knob on turning spurt water device, makes the arc boss of knob be stopped at "ON", opens blowoff valve simultaneously and can realize the action of backwashing filter core outer wall, makes cleaning, blowdown work simple;
Quick demounting conveniently changes core, only need the knob on turning spurt water device, the arc boss making knob is stopped at the center of "on" and "off", can stagger the passage of Inlet and outlet water and cut off the water supply, again that shell body is the most detachable together with the middle seat 90-degree rotation being spirally connected, again shell body is separated with the middle seat being spirally connected, then exit filter element and be convenient for changing.
This utility model has an advantage of above 2 aspects, thus brings the very big facility in use, its compact conformation, produces easy to assembly, is not required to any electric energy, environmental protection and safe and reliable.
