On-line self-circulation cleaning device for cooling conduit

Abstract

The invention discloses an on-line self-circulation cleaning device for a cooling conduit, and relates to the technical field of cooling conduit cleaning. The on-line self-circulation cleaning device comprises a first-stage water tank, a second-stage water tank and a circulating pump, a water return chamber and a water purification chamber in the first-stage water tank are communicated through a filter plate, and the water return chamber is connected with a first-stage blow-off pipe; a circulating water return pipe is connected between the water return chamber and a cooling water return port of the cooling conduit; a water return branch pipe between the cooling water return port and a cooling water return main pipe is used as a circulating water return bypass pipe; a water tank connecting pipe is connected between the water purification chamber and the second-stage water tank, a circulating water inlet pipe is connected between the second-stage water tank and a cooling water inlet of the cooling conduit, and a circulating pump is mounted on the circulating water inlet pipe; and a circulating water inlet bypass pipe is connected between the circulating water inlet pipe and the cooling water return main pipe, and valves are mounted in the pipelines. The problem that a cooling conduit of an existing high-speed bar rotating hub is difficult to disassemble and clean is solved.

Description

technical field [0001] The invention relates to the technical field of cooling conduit cleaning, in particular to an online self-circulation cleaning device for cooling conduits. Background technique [0002] In the circulating cooling treatment system in the metallurgical and other manufacturing industries, the cooling conduit is used as the delivery carrier of the cooling water. After long-term use, a large amount of scale will accumulate on the inner wall of the cooling conduit. When the scaling is serious, the cooling conduit will be blocked. These scales It has a great influence on the cooling effect, so the cooling duct needs to be cleaned regularly. However, for some equipment that is compact in structure and heated and baked similar to high-speed bar hubs, the cooling ducts of the rotor hubs are not easy to disassemble due to restrictions such as on-site installation, or the connection will be damaged after disassembly and cleaning. Cleaning will prolong the cleanin...
