Description

Technical Field

[0001] The present invention relates to the technical field of water circulation purification equipment, in particular to a purification device for a water circulation system of underground mining equipment. Background Art

[0002] Currently, the water circulation system for rock drills in underground mining equipment consists of a water pump, an oil-water separator, and pipelines. This system only meets the requirements for equipment operation under normal water quality conditions. However, the water quality in many mining areas is relatively hard, and long-term use of this hard water can easily cause blockage in the water circulation pipelines of underground mining equipment. Therefore, those skilled in the art have proposed a purification device for the water circulation system of underground mining equipment. Summary of the Invention

[0003] In view of the defects raised in the above background technology, a technical solution of a purification device for a water circulation system of underground mining equipment is provided.

[0004] It includes a water circulation cooling system fixed on the mining equipment, a centrifugal circulating water purification component is fixedly installed on the front side wall of the water circulation cooling system, and an acid-base proportioning box is fixedly connected to the right side wall of the centrifugal circulating water purification component;

[0005] The water circulation cooling system includes a steel structure frame, a refrigeration unit fixed in the inner cavity of the steel structure frame, and a heat exchange unit fixed on the right side of the inner cavity of the steel structure frame;
