Embodiment Construction
[0014] like figure 1 The shown underground coal slime treatment device includes a speed regulating circuit, a speed regulating controller N, and a speed-controllable driving shaft M, a driven shaft K, and a rubber belt H with a rubber rod F passing between the two shafts. In connection, other auxiliary equipments include slime box I, cover plate L, air inlet D, resistance rod G, resistance rod J, and collection box E. The speed of the driving shaft M, start and stop, etc. are adjusted through the speed adjustment controller N.
[0015] The driven shaft K and the driving shaft M are connected by a rubber belt H to form a slime conveying mechanism. The rubber belt H is arranged obliquely, and the driving shaft M is located at an inclined upper position; There is an air inlet D that passes through with the rubber rod F, the slime box I is arranged diagonally below the rubber belt H, the collection box E is connected to the diagonally above the rubber belt H, and the collection b...

The invention belongs to the field of coal mining. In order to solve the problem that coal slime flows all around a lane as a result of spray and aspirating to an underground coal mine belt head and aworking face, the invention provides a coal slime drying device which can be used anywhere in the underground coal mine. The device comprises a collecting box, a rubber belt with a rubber stick, a coal slime box, a driven shaft, a cover plate and a driving shaft. The driving shaft and the driven shaft are connected through the rubber belt to form a coal slime transfer mechanism. The rubber belt is arranged obliquely, and the driving shaft is located on the inclined top; the cover plate is parallelly arranged above the rubber belt in a spaced manner, an air inlet penetrating the rubber stick is formed in the top of the cover plate, the coal slime box is arranged obliquely below the rubber belt, the collecting box is arranged on the inclined top of the rubber belt, a resistance stick for touching and impacting the rubber stick is connected to the collecting box, and a speed regulating control device is connected out of the driving shaft. The device can be fully qualified for drying anddehydrating coal slime under the circumstance that the current underground environment is severe and the water content of the coal slime is high and low.
Description
technical field [0001] The invention belongs to the field of coal mining, and in particular relates to an underground coal slime processing device with controllable underground speed and a drying treatment process used when the coal mine underground belt head, working face slime and water are separated. Background technique [0002] Coal mines used to be crude mining technology. With the continuous improvement of technology, many college students go underground to engage in coal mining. College students have put forward many requirements for their own safety and working environment, including strict implementation of belt machine head and working face spray dust reduction, The implementation of these process procedures has brought some new problems, that is, after coal dust and water are mixed, the coal slurry water will fill the roadway. When the coal slime water is collected into it, the mixture of coal dust and water will slowly form three layers in the large volume pool,...
