Belt transfer point negative-pressure dust removal system

Abstract

The invention discloses a belt transfer point negative-pressure dust removal system, and relates to the field of dust removal of an underground coal mine. The system comprises a dust removal fan and aseal cover covered on a transfer point belt. The dust removal fan is connected with the seal cover through a dust hood and dust hood side plates. One side of the seal cover is provided with a deviceplatform. The dust removal fan is on the device platform. The dust removal fan is internally provided with a water sprayer, a vibration wire filter plate, a hydrocyclone, an air outlet, and a motor from right to left in sequence. The water sprayer is on an air inlet of the dust removal fan. The bottom between the hydrocyclone and the air outlet is provided with a dust mud drain outlet. The motor is on the tail part of the dust removal fan. After the system comes into use, influence of dust on the device and human bodies can be ignored, a problem that dust of belt transfer points of a large coalmine exceeds standard is solved, and dust is effectively controlled.

Description

technical field [0001] The invention relates to the field of dust removal in underground coal mines, in particular to a negative pressure dust removal system for a belt transfer point. Background technique [0002] Dust is one of the main factors that affect the efficient, safe and clean production of coal mines. It not only pollutes the environment, but also consumes raw materials and is extremely harmful to the health of workers. It will also accelerate the wear and tear of equipment and reduce product quality. Among them Coal dust particles can also cause an explosion when the concentration reaches a certain level. [0003] The dust in Tashan Mine is mainly coal dust, followed by particles of rock and other substances. When the dangerous coal dust reaches a certain concentration, it can explode violently under the action of the detonation heat source, which poses a serious threat to the safety of workers and can instantly destroy workplace equipment. Coal dust explosion...

Problems solved by technology

[0004] In order to solve the problem that the dust at the transfer point of the belt system exceeds the standard, the present invention provides a negative pressure dust removal system at the transfer point of the belt system

[0006] The present invention was invented aiming at the dust production characteristics of the belt reloading point. It mainly adopts the method of suppressing dust diffusion, and installs a negative pressure dust removal system to solve the problem of excessive dust at the reloading point. It mainly includes a dust removal fan and a belt covering the reloading point. The airtight cover on the upper part can reduce the dust by processing the dust in the airtight cover. The dust removal fan is connected with the airtight cover through the dust suction hood and the side plate of the dust suction hood, and sucks the dust from the airtight cover. On one side of the airtight cover There is an equipment platform, and the dust removal fan is installed on the equipment platform. The components in the dust removal fan are water sprayer, vibrating string filter plate, cyclone, air outlet and motor from right to left. The water sprayer is at the air inlet of the dust removal fan. It is used to spray high-pressure water mist into the fan. The vibrating wire filter plate itself contains fibers with self-cleaning ability. Therefore, when the water sprayer sprays on it, the fibers attached to the water curtain can make the dust wet, increase in weight or condense or Retention makes the fibers vibrate under the impact of the airflow through the passing dusty gas, which strengthens the fusion of water mist and dust in the dusty gas, and improves the capture of fine dust. Due to the self-purification ability of the vibrating wire filter plate's own fibers And the sprayer continuously sprays to the vibrating wire filter plate, so that the dust-laden gas passing through the vibrating wire filter plate becomes a moist dust-laden liquid air flow; Converge to the inner wall of the dehydration cylinder to form a sewage flow, and the settled sewage flow is finally discharged out of the machine through the dust and mud sewage outlet. The function of the motor is to provide power for the entire dust removal fan
