Abstract
The invention relates to an improved structure for a filter device. The improved structure for the filter device comprises a fixed ring, wherein a two-layered filter screen is arranged on the fixed ring; the filtration pore size of the internal layer filter screen is larger than that of the external layer filter screen; at least two cavities are formed in the ring body of the fixed ring; the adjacent cavities are separated by a separating plate; the cavities are communicated with the internal space of the two-layered filter screen; the fixed ring is provided with hooks. According to the invention, the two-layered filter screen is arranged, and the internal space between the internal layer filter screen and the external layer filter screen is communicated with the external space through the cavities formed in the ring body of the fixed ring, so that on one hand, the internal space is convenient for collection of filter residues, and on the other hand, the cavities are convenient to remove the collected filter residues regularly to prevent the filter speed from being influenced by the filter residues.
Description
Technical field
The present invention relates to field of petroleum machinery, particularly, relate to a kind of filter modified node method.
Background technology
In the recovery process of oil, mainly comprise several operations such as oil drilling, petroleum transportation, petroleum storage and PETROLEUM PROCESSING.In Process of Oil Well Drilling, part rock stratum fragment and some other rubbish can remain in petroleum liquid, if these rubbish enter into petroleum pipeline together along with petroleum liquid, not only can increase the load of petroleum pipeline, reduction is the efficiency of oil exploitation, petroleum pipeline is blocked in addition, so need to arrange the filter modified node method being used for filtering oil liquid in petroleum pipeline time serious.
Existing filter modified node method can not carry out collection process to filter residue.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of filter modified node method, to overcome the problem that existing filter modified node method can not carry out collecting to filter residue process.
The present invention's adopted technical scheme that solves the problem is: filter modified node method, comprise retainer ring, retainer ring is provided with double-layer filtering net, the filter pore size of internal layer screen pack is greater than the filter pore size of outer filter net, 2 cavitys are at least provided with in the ring body of retainer ring, separated by dividing plate between adjacent cavities, cavity is communicated with the inner space of double-layer filtering net, and described retainer ring is provided with hook.
The existing screen pack for petroleum pipeline normally arranges in petroleum import place the screen pack that can cover import, although the effect of filtration can be played, but this screen pack can not carry out collection process to filter residue, internal layer screen pack of the present invention is arranged on the inwall of retainer ring, described outer filter net is arranged on the outer wall of retainer ring, double-layer filtering net comprises internal layer screen pack and outer filter net, the inner space of described double-layer filtering net specifically refers to the gap between internal layer screen pack and outer filter net, described cavity is for being communicated with inner space and the space outerpace of double-layer filtering net, described hook is used for filter modified node method to be fixed in petroleum pipeline, the course of work of the present invention: entrance point filter modified node method being arranged on petroleum pipeline, make oil successively through internal layer screen pack and outer filter net, larger-size filter residue is stopped by internal layer screen pack, the filter residue of reduced size is stopped by outer filter net, be collected in the inner space of double-layer filtering net, after filtering one end time, filter modified node method is taken out, the filter residue of inner space is poured out from cavity, avoid being collected in the filter residue blocking filter opening of inner space and then the speed of impact filtration, the present invention is by arranging double-layer filtering net, internal layer screen pack is communicated with space outerpace by the cavity arranged in retainer ring ring body with the inner space of outer filter net, on the one hand, the collection of filter residue is convenient in the setting of inner space, the filter residue that the setting of cavity is convenient to collecting regularly is removed, filter residue is avoided to affect the rate of filtration, so, instant invention overcomes the problem that existing filter modified node method can not carry out collecting to filter residue process.
Further, the upper end of dividing plate both sides is provided with groove, and bottom portion of groove is provided with spring, and arc screen pack two ends are provided with the clamp with groove fit, arc filter network card is located between 2 grooves, and the filter pore size of arc screen pack is less than the filter pore size of double-layer filtering net outer filter net.
Structure like this makes that arc screen pack is detachable to be arranged between 2 dividing plates, the setting of arc screen pack avoids filter residue to enter into the inner space of internal layer screen pack and outer filter net by cavity, and then arc screen pack avoids the problem of the blocking of double-layer filtering net.
Further, the size of arc screen pack and the dimensional fits of cavity.
Avoid there is space between arc screen pack and cavity, affect the filter effect of arc screen pack.
Further, retainer ring adopts hard aluminium alloy to make.
Hard aluminium alloy is prior art material, has the advantages that the large quality of hardness is light, can meet the hardness needs of retainer ring, can reduce weight again.
Further, retainer ring and dividing plate are formed in one structure.
Describedly one-body moldedly specifically refer to that retainer ring and dividing plate are by peculiar mold injection molding, integrated formed structure good stability.
Further, double-layer filtering net adopts aluminium wire to make.
Aluminium wire is prior art material, can avoid corrosion, can avoid again the problem of rotting as the materials such as rubber cause.
To sum up, the invention has the beneficial effects as follows:
The present invention is by arranging double-layer filtering net, internal layer screen pack is communicated with space outerpace by the cavity arranged in retainer ring ring body with the inner space of outer filter net, on the one hand, the collection of filter residue is convenient in the setting of inner space, the filter residue that the setting of cavity is convenient to collecting regularly is removed, and avoids filter residue to affect the rate of filtration.
