Abstract
The utility model discloses a wedge-shaped sieve tube, which comprises flanges, reinforcing ribs and filtering strands, wherein the flanges include an upper flange and a lower flange, the upper flange and the lower flange are annular; the upper flange and the lower flange are vertically provided with a plurality of reinforcing ribs; the filtering strands are spirally coiled at the inner sides of the reinforcing ribs; the filtering strands and the reinforcing ribs are fixed via welding, the reinforcing ribs and the upper flange are fixed via welding, and the reinforcing ribs and the lower flange are fixed via welding. According to the wedge-shaped sieve tube, the sections of the filtering strands are triangular, a gap formed between the filtering strands is a trapezoidal filtering gap, and the structural filtering efficiency is more than three times as high as a slotting type sieve tube; back wash can be completed by utilizing high-pressure water flow in the sieve tube, so that the wedge-shaped sieve tube is difficult to block, quick and convenient; the wedge-shaped sieve tube is made of stainless steel, so that the service life is long.
Description
Technical field
The utility model relates to filtration art, is specifically related to a kind of wedge shape screen casing.
Background technology
While pumping operation at present under oil well, the foreign material such as sand and dust easily enter in oil, and in order to stop the foreign material such as sand and dust to enter in oil, at present, what generally take is cutting seam sieve tube, and its filter efficiency is low, and oil seepage hole is easily subject to the obstruction of sandstone, affects oil impregnate amount.
Utility model content
For solving the problems of the technologies described above, it is high that we have proposed a kind of filter efficiency, and be easy to backwash, be difficult for stopping up, and the wedge shape screen casing of long service life.
For achieving the above object, the technical solution of the utility model is as follows:
A wedge shape screen casing, comprises flange, reinforcing rib and filtering strap; Described flange comprises upper flange and lower flange, and described upper flange and lower flange are annular; Described upper flange and lower flange be vertically provided with some described reinforcing ribs; Inside described reinforcing rib, spiral winding is provided with described filtering strap; Fixed form between described filtering strap and reinforcing rib is welding, and the fixedly French between described reinforcing rib and upper flange, reinforcing rib and lower flange is welding.
Preferably, the cross section of described filtering strap is triangle.
Preferably, the cross section of described reinforcing rib is trapezoidal.
Preferably, the material of described wedge shape screen casing is stainless steel.
By technique scheme, the cross section of filtering strap of the present utility model is triangular in shape, and the gap forming between described filtering strap is a trapezoidal time of filtration, and its structure filter efficiency is higher more than 3 times than slit type screen casing; In inside, with High-Pressure Water, can complete backwash, be difficult for stopping up, efficient and convenient; Its material is stainless steel, thereby its long service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

The specific embodiment
Below in conjunction with embodiment and the specific embodiment, the utility model is described in further detail.
The utility model provides a kind of wedge shape screen casing, and its filter efficiency is high, and be easy to backwash, be difficult for stopping up, and long service life.
Embodiment
As shown in Figure 1 and Figure 2, a kind of wedge shape screen casing, comprises upper flange 1, lower flange 2, reinforcing rib 3 and filtering strap 4; Described upper flange 1 and lower flange 2 are annular; Described upper flange 1 and lower flange 2 be vertically provided with some described reinforcing ribs 3; Described reinforcing rib 3 inner side spiral windings are provided with described filtering strap 4; The fixed form that described filtering strap 4 and reinforcing rib are 3 is welding, and the fixedly French between described reinforcing rib 3 and upper flange 1, reinforcing rib 3 and lower flange 2 is welding; The cross section of described filtering strap 4 is triangle; The cross section of described reinforcing rib 3 is trapezoidal; The material of described wedge shape screen casing 4 is stainless steel.
By technique scheme, the cross section of filtering strap of the present utility model is triangular in shape, and the gap forming between described filtering strap is a trapezoidal time of filtration, and its structure filter efficiency is higher more than 3 times than slit type screen casing; In inside, with High-Pressure Water, can complete backwash, be difficult for stopping up, efficient and convenient; Its material is stainless steel, thereby its long service life.
Above-described is only a kind of wedge shape screen casing preferred embodiment of the present utility model; should be understood that; for the person of ordinary skill of the art; do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
