Description
Technical field
The utility model belongs to oil exploitation machinery, relates generally to a kind of oil exploitation water filter that water filling is used in the oil field.
Background technology
For reducing the well-flushing frequency in the oil exploitation process, improve oil recovery amount, satisfy environmental protection requirement, before water carries out the water filling operation to oil well, all need to carry out filtration treatment, to guarantee the cleaning of water quality to injecting water.At present, be used for comprising hydrotreaters such as wound form, filter net type that after operation a period of time, such filter all need stop production and carry out filter core and change or clean to what inject water filtration, the operating cost height, labour intensity is big, and has reduced oil well output.For overcoming the problem that above-mentioned prior art exists, the applicant had once developed a kind of backwashing water filter, need not during operation to stop production and change or clean filter core, overcome the defective that prior art exists, but, because the unadjustable variation of fit clearance between the outer filter cylinder that cooperatively interacts and the center chimney filter, can not satisfy and adapt to different filtering accuracy requirements, range of application is narrow, and different water filtration precision are needed repeatedly more switching center9's chimney filter.
Summary of the invention
The purpose of this utility model is exactly the problem that exists at above-mentioned prior art, design provides a kind of crack streaming backwashing water filter of new construction, reaches to adapt to and the purpose that satisfies different water filtration required precisions, expansion backwashing water filter application scope, assurance transaction capabilities, use simple and convenient.
Basic design of the present utility model is, crack streaming backwashing water filter comprises housing and is fitted in joint, feed tube, outer filter cylinder, center chimney filter, drain pipe on the housing, in the filter cylinder, center chimney filter outer surface and outer filter cylinder inner surface integral body are the equal cone shape that cooperatively interacts of tapering outside in its center chimney filter inserting.By securing member the fluid cylinder flange is installed on a side end of housing, the seal section on the fluid cylinder flange is sealed and matched with outer filter cylinder one side end face; Pressure measuring valve is fitted on the fluid cylinder flange, and is communicated with the center chimney filter; The pressure-relief valve connection is installed on the pressure measuring valve inlet end pipeline; Blow-off pipe is fitted on the housing.
The utility model is simple and reasonable, can adapt to and satisfies different water filtration precision job requirements, and applied range is manipulated easy and conveniently, and the operation fault is few, and operation quality is good, and operating cost is cheap, long service life.

Accompanying drawing is a crack streaming backwashing water filter general structure schematic diagram.
Piece number among the figure:
1, joint, 2, housing, 3, blow-off pipe, 4, seal section, 5, fluid cylinder flange, 6, pressure-relief valve, 7, pressure measuring valve, 8, securing member, 9, feed tube, 10, outer filter cylinder, 11, center chimney filter, 12, drain pipe.
The specific embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.Crack streaming backwashing water filter comprises housing 2 and is fitted in joint 1, feed tube 9, outer filter cylinder 10, center chimney filter 11, drain pipe 12 on the housing 2, in the filter cylinder 10, center chimney filter 11 outer surfaces and outer filter cylinder 10 inner surface integral body are the equal cone shape that cooperatively interacts of tapering outside in its center chimney filter 11 insertings.By securing member 8 fluid cylinder flange 5 is installed on a side end of housing 2, the seal section 4 on the fluid cylinder flange 5 is sealed and matched with outer filter cylinder 10 1 side end faces; Pressure measuring valve 7 is fitted on the fluid cylinder flange 5, and is communicated with center chimney filter 11; Pressure-relief valve 6 connections are installed on the pressure measuring valve 7 inlet end pipelines; Blow-off pipe 3 is fitted on the housing 2.
During the water filtration operation, close blow-off pipe 3 and pressure measuring valve 7, open pressure-relief valve 6, feed tube 9 and drain pipe 12, the injection water that needs filtration treatment is in feed tube 9 enters housing 2 chambeies, filtration by outer filter cylinder 10 and center chimney filter 11, clean water is injected in the water injecting pipeline through drain pipe 12 in center chimney filter 11 center cavities, remains in after impurity is filtered in the water between housing 2 internal faces and outer filter cylinder 10 outside wall surface and outer filter cylinder 10 inner conical walls and the center chimney filter 11 male-tapered wall gaps.When crack streaming backwashing water filter is cleaned the maintenance operation, close pressure-relief valve 6 and feed tube 9, open blow-off pipe 3, pressure measuring valve 7 and drain pipe 12, press water enters in the fluid cylinder flange 5 by pressure measuring valve 7, the center chimney filter 11 that is in the home position through seal section 4 promotions moves axially, and regulates gap between increase center chimney filter 11 conical outer surfaces and outer filter cylinder 10 cone-shaped inner surfaces; The notes well clean water that has certain pressure after the filtration is returned from drain pipe 12 as backwashing water and is charged in center chimney filter 11 center cavities, through center chimney filter 11 enter center chimney filter 11 and outside between the filter cylinder 10 in the tapered gaps, carry impurity in it in the lump outside outer filter cylinder 10 cinclides enter between filter cylinder 10 and housing 2 gaps, again with impurity in it and backwashing water in the lump outside blow-off pipe 3 displacers, finish this device back flush operation.Center chimney filter 11 is positioned at the home position of outer filter cylinder 10 to be determined by manual adjustment, to realize the gap adjustment between the poppet surface in center chimney filter 11 outer poppet surfaces and the outer filter cylinder 10, adapts to different water filtration required precisions.
