The specific embodiment
Below in conjunction with accompanying drawing, a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subjected to the restriction of the specific embodiment.It will be appreciated that, mentioned in the following embodiment of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side " be all take the direction shown in each figure as benchmark, these words that are used for limiting direction only are for convenience of explanation, do not represent the restriction to the concrete technical scheme of the present invention.
As shown in Figure 1 (arrow represents water (flow) direction among the figure), the liquid medium of fluid filter system of the present invention is water, consisted of by two circulatory systems, wherein, circulatory system A realizes the filtering function of system water as filtering major cycle, and circulatory system B is as the secondary circulation of negative pressure, can form powerful negative pressuren zone at the water return pipeline (device water outlet oral region) of major cycle, thereby realize the barometric gradient between the filter intake-outlet.
Wherein, circulatory system A comprises: filtering tank, intake pump 2, the first pressure regulator valve 3, outlet valve 4 and storage tank 5.As shown in Figure 2, filtering tank comprises: cylindric tank body 11, and be arranged on flow guide sleeve 12, homogenizing plate 13, filtering bodies 14 and a plurality of Pressure gauge 15 in this cylindric tank body 11.Cylindric tank body 11 vertically arranges, the top offers delivery port 16, delivery port 16 by pipeline be divided into again two branch lines after outlet valve 4 is connected, wherein a branch line is connected into storage tank 5, another branch line is connected into the water sprayer side direction suction side of circulatory system B; Flow guide sleeve 12 is arranged on the bottom of tank body 11, this flow guide sleeve 12 is tubulose, upper port has the mounting flange that extends radially outward, when flow guide sleeve 12 is arranged on tank body 11 bottom by this mounting flange, below mounting flange, form diversion cavity 17, the water inlet 18 of filtering tank is opened on the sidewall of tank body 11, face flow guide sleeve 12 sidewalls of vertical setting, water inlet 18 by pipeline successively with after the first pressure regulator valve 3, intake pump 2 are connected, access again the flow that storage tank 5, the first pressure regulator valves 3 are used for regulating water inlet 18; Homogenizing plate 13 is arranged on flow guide sleeve 12 tops, is uniform orifice plate, can control water flow stationary and upwards flow, and the aperture is not less than φ 10.And filtering bodies 14 right sides are arranged on homogenizing plate 13 tops, can select the larger double braid net of intensity, also can select other filter medium.After water enters tank body 11 by water inlet 18, pass through again upwards water conservancy diversion of tubulose flow guide sleeve 12, and then by after homogenizing plate 13 current-sharings, enter filtering bodies 14 and filter.A plurality of Pressure gauge 15(can be four) vertical direction is disposed on the sidewall of tank body 11, and the pressure of Pressure gauge 15 point is positioned near the central axis of tank body 11.
Circulatory system B comprises: water sprayer 6, the second pressure regulator valve 7 and compression pump 8.Wherein, the delivery port 16 of tank body 11 is connected into the side direction suction side of the water sprayer 6 of circulatory system B by pipeline and the wherein branch line after outlet valve 4 is connected, and the water inlet end of water sprayer 6 by pipeline successively with after the second pressure regulator valve 7, compression pump 8 are connected, access again storage tank 5.The water side of water sprayer 6 is by pipeline access storage tank 5.
As shown in Figure 1, during filtration, the filtering tank outlet pipeline is told the side direction suction side of branch road access water sprayer 6, reduce the force value (also can adopt the mode that vacuumizes at export pipeline) of delivery port 16 with this, will be in mineralization pressure gradient between intake-outlet, on the short transverse of filtering tank, delivery port negative pressure value out at this moment, water inlet is the malleation value, like this in the position, middle part of filtering tank with regard to the mineralization pressure lower position, even zero-pressure position.This pressure lower position can be determined by the reading of a plurality of Pressure gauges 15, and filtering bodies 14 is arranged on this pressure lower position or zero-pressure position, to reduce by the adhesion of filtering thing, avoids stopping up.
For at tank body 11 interior mineralization pressure lower positions, even the zero-pressure position, need the barometric gradient slope of curve in the controlled filter tank.The barometric gradient slope of curve can be controlled the flow of intake-outlet by the aperture of regulating the first pressure regulator valve 3, outlet valve 4, adjusting intake pump 2 is controlled intake-outlet pressure and controlled; Flow and the pressure that also can change by regulating the second pressure regulator valve 7 and compression pump 8 the jet bypass are realized, when being the increasing of jet flow and pressure, it is large that barometric gradient in the filter becomes, requiring the filter port of export is negative pressure value, entrance point is the malleation value, certain position, middle part will produce the zero-pressure position like this, and we just choose this location arrangements filtering bodies 14.Slope curve two, four-quadrant, the slope absolute value scope is the smaller the better in principle, near general slope can be controlled at-1～0 for well.
This fluid filter system is simple and reasonable; By reducing filter body suffered medium pressure liquid in filter plant, and then reduce by filtering thing adhesion, so that should be difficult for stopping up by the filter body, good filtration effect, the flushing recycling is effective.
More than disclosed only be several specific embodiment of the present invention, still, the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
