Problems solved by technology

In this way, when the next simulation experiment is carried out, if the original experimental device is used, the measured data does not have objective authenticity, and thus cannot reflect the due experimental phenomenon and results.
If a new simulated experimental device is made according to the actual working face again, it will consume too much experimental funds, resulting in economic waste

Embodiment Construction

[0020] The present invention will be further described in detail according to the examples below.

[0021] The practical adjustable working flour dust simulation experiment device will be described in more detail below in conjunction with the embodiments.

[0022] figure 1 - Fig. 6 is the various views of the practical adjustable working flour dust simulation experiment device.

[0023] Adjustable working flour dust simulation experiment device, the whole air duct ( figure 1 ) is composed of a simulated wind source and 3 square plastic pipes that can be spliced, respectively representing the wind source area 11 of the mine ( figure 2 ), Inlet Lane 12 ( image 3 ), coal mining face 13 ( Figure 4 ) and Huifeng Lane 14 ( Figure 5 ). The wind source area is composed of a small fan 1, a baffle plate 2, and a wind source pipe 3. Small-sized blower fan 1 is connected with the wide mouth of wind source pipeline 3, and is sealed with adhesive tape all around, and the middle p...

Abstract

The invention discloses an adjustable working face dust simulation experiment device. The adjustable working face dust simulation experiment device comprises an air source area, an air inlet way, a working face and an air return way which are sequentially connected with one another, wherein the air inlet way, the working face and the air return way are splicing square plastic pipelines, the air source area comprises a small fan, a baffle board and an air source pipeline, the small fan is in seal connection with a wild opening of the air source area, the baffle board which can be vertically adjusted is arranged in the middle above the wide-opening pipeline to control air forces, and a plurality of small equidistant circular holes are arranged at the tops of pipelines of the working face, the air inlet way and the air return way.

Description

technical field [0001] The invention relates to an experimental device, in particular to an adjustable working flour dust simulation experimental device which provides scientific, objective and convenient conditions for studying the ventilation of underground coal mining working faces, the measurement of dust migration, dispersion, density, and concentration. Background technique [0002] In the process of coal mine production, dust is one of the main disasters that plague the safe production of coal mines. If convenient equipment is developed to simulate the dust migration situation in the underground coal mining face, and various measuring instruments are used to collect experimental data and analyze them, it is necessary to study the migration of dust in the mine, solve the problem of dust disasters, and prevent accidents. has a very important meaning. At present, with regard to the simulation experiment device of working flour dust, the disposable experimental device is...
