Speed-adjustable dust collection crushing device for crushing coal mine

Abstract

The invention discloses a speed-adjustable dust collection crushing device for crushing a coal mine. The speed-adjustable dust collection crushing device comprises a crushing cavity I, a crushing cavity II, a first motor, a rotating shaft, crushing knives, feed openings, a dust collection device I, a bearing, a discharge opening and a dust collection device II, wherein the crushing cavity is positioned above the crushing cavity II; the feed openings are correspondingly formed in two sides of the cavity body of the crushing cavity I; the discharge opening is formed below the crushing cavity II;the dust collection device I and the dust collection device II are correspondingly arranged on the crushing cavity I and the crushing cavity II; the first motor is fixedly arranged outside the crushing cavity I; the output shaft of the first motor is connected with a transmission shaft through a coupler; the crushing knives are fixedly arranged on the rotating shaft; a filter screen is arranged below the crushing cavity I and is obliquely placed in a box body; a pair of baffles is fixedly arranged between the filter screen and the crushing cavity I; and the outlet of the baffles is formed above the oblique segment of the filter screen.

Description

technical field [0001] The invention relates to the technical field of ore mechanical equipment, in particular to an adjustable-speed dust-absorbing and crushing device for crushing coal mines. Background technique [0002] In mine production, the initially mined iron ore has large blocks, which are not conducive to the transportation of ore. Generally, ore crushing devices are installed inside the mine to crush the iron ore with large blocks before transporting. The current When the ore crushing device is working, due to the large ore block, it is easy to cause damage to the crushing chamber, and the crushing efficiency is not high during crushing, and some iron ore with large blocks will not be crushed up to the standard. The requirements for coal are getting higher and higher, and more and more customers no longer need directly mined coal, but coal powder or small-sized coal, but when the coal ore is crushed, a lot of dust will be generated, not only It will cause certai...

Problems solved by technology

[0002] In mine production, the initially mined iron ore has a large block, which is not conducive to the transportation of ore. Generally, an ore crushing device is installed inside the mine to crush the iron ore with a large block and then transport it. The current When the ore crushing device is working, due to the large ore block, it is easy to cause damage to the crushing chamber, and the crushing efficiency is not high during crushing, and some iron ore with large blocks will not be crushed up to the standard. The requirements for coal are getting higher and higher, and more and more customers no longer need directly mined coal, but coal powder or small-sized coal, but when the coal ore is crushed, a lot of dust will be generated, not only It will cause certain pollution to the air environment, and cause certain harm to the health of operators. At the same time, most of the crushing equipment will not be completely crushed, resulting in a certain amount of waste.
