Description
Technical Field
The utility model relates to the technical field of rotary vibration sieves, in particular to a punching screen with high aperture ratio.
Background
The rotary vibration sieve is a high-precision fine powder sieving machine. The method is widely applied to the industries such as chemical industry, abrasive ceramic industry, food industry, paper making industry, metallurgy industry, pharmaceutical industry, environmental protection and the like. The screen as a key part determines the quality, efficiency and yield of screening, and the screening efficiency and the screening yield are most concerned by users. The rotary vibrating screen in the current market is mainly integrally used after a metal wire woven screen mesh is bonded with a section bar net rack, or a circular perforated punching plate is adopted as the screen mesh. The common shortcoming of both is that the percent opening is not high, and the blind area of screen cloth is too much promptly, and can't simply improve: in order to increase the aperture ratio, the wire diameter of the metal wire must be reduced, thereby reducing the service life of the screen. The screen cloth of circular trompil punching plate preparation is difficult wearing and tearing, and life is guaranteed, but the promotion space of percent opening is not high, even draw adjacent trompil to "tangent" also has triangle-shaped blind area.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the existing defects, provides the punching screen with high aperture ratio, has simple structure and convenient installation, can improve the aperture ratio of the screen to the maximum extent, has uniform and consistent blind areas and uniform hole distribution, is beneficial to screening, has more occupied proportion of screen holes in the same screening area, can obviously improve the screening efficiency and yield of the screen, and can effectively solve the problems in the background technology.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a high aperture ratio screen cloth that punches a hole, includes raw materials contact tube, rack carriage, screen cloth and annular carriage, be equipped with the discharge gate in the middle of the annular carriage side, and discharge gate one side is equipped with the raw materials contact tube, and the inboard lower extreme joint of annular carriage has the rack carriage, and the last fixed surface of rack carriage has the screen cloth, and the upper surface of screen cloth is higher than the lower extreme of raw materials contact tube, the screen cloth is circular structure, and the edge and the rack carriage welding of screen cloth, and the screening through-hole on the screen cloth is regular hexagon structure, and the screening through-hole through regular hexagon structure can increase the screen cloth aperture ratio.
Furthermore, the raw material delivery pipe is connected with the annular supporting frame in a welding mode, and the raw material delivery pipe is of an L-shaped structure.
Further, evenly be equipped with the joint through-hole on the rack carriage, be equipped with the joint groove that corresponds with the joint through-hole on the annular carriage, be equipped with joint spare between joint through-hole and the joint groove.
Furthermore, the upper end and the lower extreme edge of annular carriage are L type structure, and the cross-section of rack carriage is L type structure.
Compared with the prior art, the utility model has the beneficial effects that: the screening through-hole through regular hexagon structure can increase the screen cloth percent of opening, fixes the rack carriage on annular carriage through the joint spare for it is more convenient to install, this high percent of opening screen cloth that punches a hole, simple structure, simple to operate not only can maximize the percent of opening that improves the screen cloth, and the blind area is even unanimous, and the cloth hole is even, does benefit to the screening, and the shared proportion of sieve mesh is more in the same screening area, just can show the screening efficiency and the output that improve the screen cloth.
