The ends of the entrance and the exit are arranged with clamp or thread. The lower portion is provided with an end for thread connection, wherein a drum-type filter element is arranged on the top. A cylindrical inner container is arranged through the filter element center, wherein a cylindrical durable alnico is arranged. The inner container is inserted in the crater of coaxial line arranged on the shell and end. The utility model has the advantage of large flux, good magnetization effect, small liquid resistance, simple structure, easy installation, good durability and easy maintenance.

Description

The magnetic high pressure filter

One, technical field

The utility model relates to a kind of oil field used oil and water filters under development, specifically a kind of magnetic high pressure filter.

Two, background technology

The original filter of using of hydraulic jet pump is the filter screen type, owing to only filter for one-level, can filter, stop the bigger impurity of particle, and can't purify the more tiny mechanical admixture of particle, therefore often causes the obstruction of hydraulic jet pump nozzle; Simultaneously, this filter screen type filter sediment space is limited, filter screen very easily takes place stop up, and causes liquid flowing resistance to become big, and power fluid pressure reduces, and has influenced the production effect of hydraulic jet pump, and this kind filter easily becomes rusty, and causes maintenance difficult, and service life is short.

Three, summary of the invention

The purpose of this utility model provides a kind of magnetic high pressure filter, solves existing problem in the above-mentioned prior art.

The technical solution of the utility model realizes in the following manner:

The utility model is made up of housing, filter core, permanent-magnet steel and inner bag, it is characterized in that housing establishes cylindrical or rectangle, the week side is provided with an import in its underpart, all at an upper portion thereof sides are provided with an outlet, import and export the end and are provided with clip or screw thread, are provided with the plug that is threaded in its bottom, top is provided with the drum-type filter core within it, pass the filter core center and be provided with a cylindrical inner bag, cylindrical permanent-magnet steel is housed in the inner bag, inner bag is inserted in the shrinkage pool of coaxial line set on housing and the plug;

At inner bag is the high temperature high voltage resistant plastics, and two ends are with the stainless steel magnetic shield of barrel formula, is welded with the cross bracing frame of filter core outside the tank in the middle part of the week.

Filter core is made as stainless steel drum shape filter core, and filter core two ends diameter is big, and seals with inner walls.

This magnetic high pressure filter adopts domestic advanced permanent magnetism technology, is that filter and magnetic scale control device are combined, and forms precipitation, absorption, filtration, the multistage water treatment mode of magnetic scale control, and novel structure is reasonable in design.The high voltage power liquid that this magnetic high pressure filter is not only applicable to water and pump oil pumping process matching filters; and can be widely used in fields such as oil well water mixing flow process low press filtration, well water filling and oil and gas multiphase flow, the harm that can effectively purify water, avoid bulky grain mechanical admixture, fibrous foreign material that pipe fitting, valve and flowmeter etc. are brought.

Compare characteristics such as have that magnetic flux is big, magnetization is effective, liquid flowing resistance is little, simple in structure, easy for installation, long service life, maintenance are easy with conventional one-level screen pack type filter.

Five, the specific embodiment

For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:

As shown in Figure 1, the utility model is made up of housing 1, filter core 2, permanent-magnet steel 3, inner bag 4, plug 5 and cross bracing frame 6.Housing is cylindrical, be provided with an import in its underpart, be provided with an outlet at an upper portion thereof, import and export the end and be provided with the clip head, in its bottom a plug that is threaded is arranged, top is provided with the drum-type filter core within it, passes the filter core center and is provided with a cylindrical inner bag, cylindrical permanent-magnet steel is housed in the inner bag, and inner bag is inserted in the shrinkage pool of concentric set on housing and the plug;

As shown in Figure 2, the magnetic high pressure filter is the high voltage power liquid filter that aims at hydraulic jet pump oil pumping process matching.Its operation principle is according to producing the principle of repelling mutually between the like pole, after the assembling of magnetization inner bag is finished, the magnetic line of force direction that produces between the permanent-magnet steel is perpendicular to the axis of magnetization inner bag, when liquid enters filter, flow along the direction that parallels with magnetization inner bag axis, the liquid cutting magnetic line, the liquid that enters filter promptly is magnetized.Consequently the calcium in the water, magnesium ion are acted on by magnetic field, destroyed original interionic electrostatic attraction state, each ion is set up new magnetic field by the same direction of external magnetic field, cause crystallization condition to change, forming very lax crystalline material adheres on tube wall and becomes the thin and cover layer of pine of one deck, incrustation scale can not be adsorbed on the tube wall with harder structural material again, is taken away by current but generate small loose body refuse material.Meanwhile, some oarse-grained mechanical admixtures are stopped by filter core, accumulate in the mud chamber.

When installing and using, to note following item:

When 1, the magnetic high pressure filter used for the first time, coating butter was answered at threaded portion and O-ring seal place.

When 2, the magnetic high pressure filter uses, should strict press technical parameter and select use occasion, especially can not surpass temperature range, in order to avoid the demagnetization of magnet steel high temperature was lost efficacy.

Magnetic high pressure filter when 3, installing should can not level be installed by the vertical installation of Fig. 1 mode, and noted the flow direction and the inflow-rate of water turbine of liquid, notes surpassing metered flow, influences the magnetization effect of water.

Should reduce vibrations when 4, installing as far as possible, make filter failure in order to avoid damage magnet steel.

Use band shutoff import and outlet when 5, transporting, be adsorbed onto magnetization inner bag surface in order to avoid impurity enters the filter inner chamber, influence magnetization effect.

6, the magnetic high pressure filter is selected steel alloy and the processing and manufacturing of high-quality stainless steel for use, and the client is using, during maintenance, must not arbitrarily change the material of magnetization inner bag, in order to avoid leakage field or cause magnet short-cut path that magnetization was lost efficacy.

7, look impurity content and water quality condition and regularly clean filter core and inner bag.
