Description of drawings

Fig. 1 is a structural diagram of the present invention.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

The invention provides a mine raw water pool coal slime gas mixing and excavation device. Compressed air pipelines are arranged around the bottom of the raw water pool to control the intake air in sections to realize air pressure and air volume adjustment to blow the coal slime and mine water to achieve mixing and stirring. The sludge pump pumps the mixed slime into the plate and frame filter press or sludge thickening tank. The present invention only needs to use the existing compressed air in the mine to realize full-automatic control of coal slime gas mixing and dredging.

As shown in Fig. 1, specifically, the present invention includes a raw water pool 5, a trachea I10 is arranged around the outside of the raw water pool 5, and at least one trachea II 11 is arranged at the bottom of the inner periphery, and at least four trachea II 11 are arranged in the raw water pool 5 respectively. On the four sides of each side, more than one can be set on each side. Each air pipe II11 is connected to the air pipe I10 through a pipeline, and a valve 6 is set on the pipeline. The valve is an air control valve or a solenoid valve. When the valve is an air control valve, It needs to be controlled by a pneumatic controller, and when the valve is a solenoid valve, it needs to be controlled by an electric controller, such as a single-chip microcomputer, MCU, etc. The air pipe I10 is connected to the pneumatic controller 1, and the pneumatic controller 1 is connected to the air source 12. After the air from the air source 12 enters the air pipe I10, it enters the air pipe II11 in the raw water pool through the valve 6, and then sprays out to carry out the slime gas Mixing; and by controlling the opening of the valve 6, the change of the intake air volume and air pressure entering the raw water tank can be controlled, so that the gas mixing can be carried out more effectively. The above-mentioned valve 6 and air pipe I10 are all arranged outside the raw water pool, and only air pipes are arranged inside the original water pool, which is convenient for maintenance and replacement.

The raw water pool 5 is connected to the filter press 4 through the sewage pipeline, and the filter press 4 is preferably a plate and frame filter press, and the sludge pump 3 is arranged on the sewage pipeline to pump out the sludge, which is used to promptly and quickly mix the air with the air. The sludge is pumped out.

The raw water pool 5 is connected to the mine sewage water source through the sewage pipeline, and the sewage pipeline is provided with an air control valve 2, and the air control valve 2 is connected to the air source 12 through the air pipeline I9, and the air source 12, the air pipeline I9, and the air pipeline II8 Both are connected with the pneumatic controller 1. The amount of mine sewage entering the raw water pool is controlled by a pneumatic controller to make the amount of liquid inside the raw water pool appropriate.

Working principle of the present invention is:

When the raw water pool containing mine sewage needs to be desilted, the valve 6 is controlled by the pneumatic controller to open, so that the air enters the raw water pool. After the air enters the raw water pool 5, since the air pipe is arranged at the bottom of the raw water pool, the air Under normal pressure or higher air pressure, the sludge at the bottom of the pool will be blown for air mixing, the sludge at the bottom of the pool will be loosened and melted in the sewage, and the mud-water mixture after air mixing will be discharged to the filter press through the sewage pipe for sludge separate.

When the present invention is working, compressed air pipelines are set around the bottom of the raw water pool to control the intake of raw water in sections through the compressed air pneumatic controller, and the air pressure and air volume are adjusted by adjusting the valve 6, and the compressed air is blown to make the mine water and coal The mud is fully mixed and stirred to achieve pneumatic mixing. The bottom coal slime is fully mixed with an appropriate amount of mine water to form a free-flowing fluid, which is pumped by the sludge pump to the plate-and-frame filter press or sludge compression tank. The mine water raw pool coal slime gas mixing excavation process only needs to use compressed air to realize fully automatic control of gas mixing and clearing excavation.

What has been described above is only the preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, some changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the present invention. scope of protection.
