Embodiment Construction

[0009] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0010] The steps of the mine water tank fine coal slime automatic clearing and excavation processing method of the present invention are as follows:

[0011] Step 1: Start the switch, the pumping device 3 and the agitator 2 set in the mine water tank 1 start to work, the agitator 2 first stirs the deposited coal slime to mix it with water to facilitate the self-priming pumping device 3 suction, the fine coal slime water mixture is sent into the buffer device 5 through the slurry discharge pipe 4;

[0012] Step 2: The coal slime water mixture sent into the buffer device 5 is deposited in the buffer device 5 to form a stable material;

[0013] Step 3: Under the control of the start switch, the booster pump 6 installed in the outlet pipeline of the buffer device 5 is started, and the stable material in the buffer device 5 is sprayed into the dehydration devic...

Abstract

The invention fine / slurry coal slime auto cleaning technique and its device is most adaptive to cleaning the mixture of coal slurry and water in water bin in mines. By applying extracting, buffering, dehydrating, loading and other method, adopting the devices needed at each process, controlling with switches, the auto cleaning of coal slime in water bin in mines is acquired, removing the tough task of cleaning the water bin by human power, improving the piling enviorment, while lowering the number of new water bin needed, improving the general economic performance, moreover protecting the environment. Its device is rational adopted, and of long service life, time and power saving, and highly practical.

Description

technical field [0001] The invention relates to a method and equipment for automatic clearing and excavation of fine coal slime in mine water tanks, and is especially suitable for automatic clearing and excavation of fine coal slime water mixture in coal mine well water tanks. Background technique [0002] At present, the coal slime in the underground water tank of my country's coal mines has been manually cleared. Every time the water tank is cleared, a large number of people need to stand barefoot and barebacked in the slime pit, dig out the coal slime with a shovel, and then transport the coal slime to The nearby roadways are piled up on both sides, and after the coal slime is dry, it is manually loaded and transported to the ground, or directly loaded and transported to the ground. Therefore, miners not only have high labor intensity and low work efficiency when digging the water tank, but also have a bad working environment and cause mine ...
