Abstract
The utility model discloses a wave-shape hole-punching filtering board which is provided with a plurality of punching holes; the filtering board is wave shape; the hole-punching is arranged on the concave surface of the wave-shape hole-punching filtering board; the convex surface of the wave-shape hole-punching filtering board is shown as step shape; the convex surface width is smaller than the concave surface width. The wave-shape hole-punching filtering board has the advantages of high gas permeability, low consumption and ability of protecting filtering cloth.
Description
Technical field
The utility model relates to a kind of main filter element of overanxious device, more specifically to a kind of filter of new structure.
Background technology
Filter plate in the filter plant forms towards circular hole or bar hole with dull and stereotyped at present, the overcoat filter cloth, and its weak point is: air penetrability is low, and air penetrability is about 20%～30%; In order to guarantee working strength, it is thick to use sheet material, and the material consumption is big; Filter cloth be adsorbed on the hole around, suffer damage easily.
Summary of the invention
The new shape of this practicality has overcome the shortcoming of prior art, and a kind of air penetrability height is provided, and the material consumption is low, and can protect a kind of Waveform Punching Filter Board of filter cloth.
The utility model is realized by following scheme: Waveform Punching Filter Board, filter plate are provided with some punchings, and described filter plate is the waveform shape, and described punching is arranged on the Waveform Punching Filter Board concave surface.
Described Waveform Punching Filter Board convex surface is trapezoidal shape.
Described land width is less than the concave surface width.
The utility model waveform filter plate shape in wave shape, make by thin plate, it is trapezoidal that wavy surface is, the opening part broad contacts with filter cloth, bending part arc transition, top and bottom all in same plane, the one side smooth surface that contacts with filter cloth, the width of contact-making surface is less than the width of waveform concave surface, and the waveform concave surface is provided with circular hole or bar hole.
After adopting technique scheme, the contact-making surface of filter cloth and filter plate is less, and the air penetrability height can reach 50%～60%.Filter cloth contacts with filter plate is smooth, and filter cloth is had protective effect, has improved the service life of filter cloth.Adopt the thin plate waveform configuration, reduced the material consumption, improved the intensity of filter-plate structure.Adopt above technical scheme, reduced production cost, the product filter efficiency has improved 50%.
Description of drawings
Fig. 1 is the front view of the structural representation of the utility model embodiment.
Fig. 2 is the vertical view of the structural representation of the utility model embodiment.
Sequence number among the figure: 1, punching, 2, waveform shape filter plate, 3, the Waveform Punching Filter Board convex surface, 4, the Waveform Punching Filter Board concave surface.
The specific embodiment
With reference to accompanying drawing, Waveform Punching Filter Board, filter plate are provided with some punchings 1, described filter plate 2 is the waveform shape, described punching 1 is arranged on the Waveform Punching Filter Board concave surface 4, and described Waveform Punching Filter Board convex surface 3 is trapezoidal shape, and described convex surface 3 width are less than concave surface 4 width.
The utility model waveform filter plate shape in wave shape, it is trapezoidal that the corrugated is, the bending part arc transition; the plane that contacts with filter cloth is smooth, is furnished with circular hole or bar hole on the concave surface, this Waveform Punching Filter Board air penetrability height; the material consumption is low, and can protect a kind of Waveform Punching Filter Board of filter cloth.
