A kind of intelligent water source power shearer dust collector and dust removal method

Abstract

The invention belongs to the technical field of underground dust removal in coal mines, and discloses a dust collector and a dust removal method for an intelligent water source power shearer. Fixing frame; the inner air outlet of the spray air cylinder is provided with a multi-angle combined spray group, and the built-in water channel on the side wall of the multi-angle combined spray group is connected with the third water inlet branch pipe; the rear end of the driving device is connected with the first water inlet branch pipe The inner wall of the air inlet is provided with an annular spray group, which is communicated with the fourth water inlet branch pipe. The invention utilizes the central processing system to wirelessly adjust the spray flow rate and pressure of the spray rotary spray group and the multi-angle combined spray group, and the spray angle of the air duct, which can not only effectively reduce the water consumption of the spray to ensure the atomization effect, but also realize precise dust control and improve Dust fall rate. The annular spray can automatically clean the coal dust accumulated inside the spray duct due to the negative pressure, reduce the product loss rate and prolong the service life.

Description

technical field [0001] The invention belongs to the technical field of dust removal in coal mines, and in particular relates to a dust collector and a dust removal method for an intelligent water source power coal shearer. Background technique [0002] At present, the fully mechanized mining face is the place with the most serious coal dust pollution in the bottom-hole operating environment. According to the actual measurement, the highest dust concentration can reach 8000mg / m without taking any dust-proof measures. 3 , in which the cutting dust accounts for about 60% to 80% of the total dust production of the working face. High-concentration dust will not only cause pneumoconiosis, but also may cause coal dust explosion accidents under certain conditions, which seriously affects the safe production of mines. Field practical research shows that wet dust collector can effectively reduce the dust concentration of mining face. However, due to factors such as excessive size of ...

AI Technical Summary

Problems solved by technology

[0004] (1) The application of wet dust collectors for coal mining machines is a blank in the industry. Due to the large number of production equipment in fully mechanized mining faces and the complex on-site operating environment, large-scale dust collectors cannot be used in the operating environment of fully mechanized mining faces. At the same time, dust removal equipment is installed on site Difficult to maintain, lack of corresponding drive source underground

[0005] (2) Conventional spraying of coal shearers has problems such as short effective range, small atomization area, and poor dust suppression effect. At the same time, the installation angle of the dust collector is fixed. Dust source, poor dust suppression effect

[0006] (3) Existing driving components of dust collectors (pneumatic motors, electric motors, hydraulic motors) all have certain disadvantages

[0008] Main difficulty: The design requirements of the dust collector not only need to meet the size required by the mining face site, ensure the dust reduction effect of the dust collector, but also solve problems such as difficult installation and maintenance; it is difficult to ensure a good spray effect with the existing nozzles
