Abstract
The utility model relates to a longitudinal seam welded filter tube with stamping-drawing bridge-shaped holes which is used to ventilate, filtrate, avoid sands in many fields including petrochemical processing, environmental protection, wine making industry, and provisions and oil producing. This utility model includes a steel belt. The filter tube is welded by the crinkled steel belt. The stamping-drawing bridge-shaped holes are provided in the steel belt evenly, which refers to two narrow gaps formed by both sides of a bridge shaped bulge and the metal belt. Wherein the bridge shaped bulge is formed on the metal belt after stamping the belt. The width between the two narrow gaps is between 0.05mm and 2mm. The stamping-drawing bridge-shaped holes are collocating in a straight line in the metal belt and arranged at three acmes of a trigon on the metal plate. The filter tube is made of stainless steel plates or carbon steel plates, which has the advantages of simple structure, low cost, good effects in filtrating and high efficiency in filtrating.
Description
Technical field
The utility model relates to the straight weld with punching stretch arched hole of a kind ofly making at petrochemical industry, environmental protection, system fermented glutinous rice, ventilating, filter, using when keeping away sand in the industry such as grain and oil and takes over chimney filter.
Background technology
At present, the screen pipe of making at petrochemical industry, environmental protection, system fermented glutinous rice, ventilating, filter, adopt when keeping away sand in the industry such as grain and oil, be on the tube wall of metal tube, to punch mostly, this aperture, hole of getting is bigger, also need on the metallic plate after the punching, cover week or how all metal knitted nets again, just can play filter effect preferably, another mode is to adopt laser to cut the hole on metal tube, cut into the unidirectional filtering holes that narrow slit forms, adopt laser on metal tube, to cut the hole, exist the cost height, the shortcoming that filter area is little.
Summary of the invention
The purpose of this utility model be to overcome deficiency of the prior art and provide a kind of simple in structure, cost is low, chimney filter is taken in the straight weld with punching stretch arched hole of good filtration effect.
The purpose of this utility model is achieved in that and comprises steel band, screen pipe is curled by steel band and is welded, on steel band, evenly be furnished with the punching stretch arched hole, the punching stretch arched hole is meant on steel band and forms bridge shape projection through punching press, two narrow slits that form between the both sides of while bridge shape projection and the steel band.
Article two, the width of narrow slit is between the 0.05-2 millimeter.The punching stretch arched hole is arranged in a linear on steel band.The punching stretch arched hole is isosceles triangle and arranges on metallic plate.The material of described screen pipe adopts stainless steel or carbon steel sheet.
The utlity model has simple in structure, cost is low, good filtration effect, advantage that filter efficiency is high.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a punching stretch arched hole structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises steel band 1, and screen pipe is curled by a steel band 1 and is welded, and forms a vertical masonry joint.Evenly be furnished with punching stretch arched hole 2 on steel band 1, the punching stretch arched hole is meant on steel band 1 and forms bridge shape projection 3 through punching press, two narrow slits that form between the both sides of while bridge shape projection 3 and the steel band 1.
Article two, the width of narrow slit is between the 0.05-2 millimeter.Punching stretch arched hole 2 is arranged in a linear on steel band 1.Punching stretch arched hole 2 is isosceles triangle and arranges on metallic plate 1.The material of described screen pipe adopts stainless steel or carbon steel sheet.
As shown in Figure 2, the width of two narrow slits 4 of the present utility model is between the 0.05-2 millimeter.Bridge shape projection 3 through punching stretch shaping processus aboralis for metallic plate 1 on.
