Intelligent water source power coal mining machine dust remover and dust removing method

Abstract

The invention belongs to the technical field of underground coal mine dust removal, and discloses an intelligent water source power coal mining machine dust remover and a dust removing method. A dustconcentration sensor, a position information receiver, a hydraulic jack, and a fixing frame are arranged at the top, the bottom and the two sides of a spraying air duct correspondingly; a multi-anglecombined spraying set is arranged at an air outlet in the spraying air duct; a water path arranged in the side wall of the multi-angle combined spraying set is communicated with a third water inlet branch pipeline; the tail end of a driving device is communicated with a first water inlet branch pipeline; and an annular spraying set is arranged on the inner wall of an air inlet and communicated with a fourth water inlet branch pipeline. According to the intelligent water source power coal mining machine dust remover and the dust removing method, a central processing system is used for wirelessly adjusting spraying flow and pressure of a spraying rotary spraying set and the multi-angle combined spraying set and spraying angle of the air duct, so that the spraying water consumption can be effectively reduced, the atomization effect is guaranteed, precise dust control can be achieved, and the dust falling rate is increased. The automatic cleaning of coal dust accumulated in the spraying air duct due to the negative pressure effect can be achieved through annular spraying, so that the product loss rate is reduced, and the service life is prolonged.

Description

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

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
