Problems solved by technology

[0003] (1) The oblique rectangular chute is easily deformed and damaged due to the erosion and wear of materials, and its service life is short;
[0004] (2) The material is prone to sticking and clogging in the chute, which leads to the blockage of the chute and affects the normal transmission;
[0005] (3) During the material falling in the chute, due to the effect of the "piston" phenomenon, it is easy to raise dust, and is pressed out to the place outside the chute outlet, causing serious air pollution
[0006] For a long time, coal, mines, material yards, thermal power plants, building materials factories and other industries, in the material transmission link, because of the above-mentioned defects in the chute, there is an urgent need for a new type of chute that can solve the problem, and so far no relevant The report of the novel chute created by the present invention

Embodiment 2

[0016] Embodiment 2 of the "three-defense" drop pipe created by the present invention, its structure includes: In the structure of Embodiment 1, a scale-shaped wear-resistant layer is also arranged on the inner plate surface of the inclined lower plate (not shown in the figure) .

[0017] According to Example 1 of the above-mentioned technical solution, the "three-defense" blanking tube prototype was trial-produced. After the intermediate test was installed and operated, the effect was very satisfactory. It was highly praised by the test participants. It is recommended to mass-produce it as soon as possible and put it on the market to satisfy the majority of users. need.

Abstract

The invention belongs to the field of material conveying machinery, and provides a 'three-prevention' blanking pipe. The 'three-prevention' blanking pipe is mainly characterized in that a pipe body of the blanking pipe is a pentahedral pipe body and is provided with three vertical side plates, one inclined side plate and one inclined lower plate; a rotary blade is arranged above the inclined lower plate; and a dust collecting mouth is formed in the inclined side plate. Compared with the existing material articulated chute, the 'three-prevention' blanking pipe has the remarkable advantages of novel structure, ingenious design, capability of effectively solving three disadvantages of the material articulated chute, wear prevention, blockage prevention and raising dust prevention.

Description

technical field [0001] The invention belongs to the field of material transmission machinery, and relates to a blanking tube, in particular a "three-proof" blanking tube. Background technique [0002] The existing material transmission system, such as the transmission of coal, ore and other materials, usually uses multi-stage belt conveyors for transfer, and the front and rear of the upper and lower adjacent two-stage belt conveyors must be connected and diverted through rectangular slide pipes. In the operation process of chute diversion and blanking, there are three main problems: [0003] (1) The oblique rectangular chute is easily deformed and damaged due to the erosion and wear of materials, and its service life is short; [0004] (2) The material is prone to sticking and clogging in the chute, which leads to the blockage of the chute and affects the normal transmission; [0005] (3) During the material falling in the chute, due to the effect of the "piston" phenomeno...
