Vacuum box for coal mine water cooling system and using method of vacuum box

Abstract

The invention discloses a vacuum box for a coal mine water cooling system and a using method of the vacuum box. The vacuum box for the coal mine water cooling system comprises a vacuum box body, wherein the vacuum box body comprises a box body of the vacuum box; one end of a water feeding tube extends to the upper end of the inner wall of the vacuum box from the lower surface of the box body of the vacuum box; one end of a water draining tube extends to the lower end of the inner wall of the vacuum box from the lower surface of the box body of the vacuum box; the other end of the water feeding tube and the other end of the water draining tube are respectively connected with a cooling pond detachably; and a water injection device and an air exhausting device are further arranged on the upper surface of the box body of the vacuum box. The method for cooling coal mine water by using the vacuum box for the coal mine water cooling system comprises the following steps: opening an air exhausting valve, starting an air exhausting pump, and extracting air in the box body of the vacuum box, the water feeding tube and the water draining tube; opening a water injection valve and injecting water in the box body of the vacuum box, the water feeding tube and the water draining tube; closing the air exhausting valve and the water injection valve after air is exhausted thoroughly; and starting a cooling water pump. By the technical scheme of the invention, the work efficiency is improved, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of coal mine water cooling equipment, in particular to a vacuum box for a coal mine water cooling system and a using method thereof. Background technique [0002] At present, the cooling method of ground equipment in coal mines is mostly water cooling. Due to poor water quality in mining areas and most factories and mines have not installed softened water equipment, the bottom valves of water pipes often cannot be closed due to long-term accumulation of water and alkali, resulting in water in the inlet and outlet pipes. In the cooling water pool, when the equipment is powered off or the cooling water pump is switched over, the air in the pipeline must be discharged again, which prolongs the opening time of the cooling system, affects the work progress, reduces work efficiency, and wastes costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a va...

[0002] At present, the cooling method of ground equipment in coal mines is mostly water cooling. Due to poor water quality in mining areas and most factories and mines have not installed softened water equipment, the bottom valves of water pipes often cannot be closed due to long-term accumulation of water and alkali, resulting in water in the inlet and outlet pipes. In the cooling water pool, when the equipment is powered off or the cooling water pump is reversed, the air in the pipeline must be discharged again, which prolongs the opening time of the cooling system, affects the work progress, reduces work efficiency, and wastes costs
