Cleaning device for inner walls of steel pipes

Abstract

The invention relates to a cleaning device for inner walls of steel pipes. The cleaning device comprises a shell; a first mounting cavity, an impeller cavity and a second mounting cavity are arrangedin the shell in sequence from top to bottom; a flow separation piece is fixedly arranged in the first mounting cavity; a water inlet ring cavity is formed between the periphery of the flow separationpiece and the inner wall of the first mounting cavity, and communicates with the impeller cavity; a guide piece is fixedly arranged at the lower end of the shell, and is positioned in the second mounting cavity; a guide cavity is formed between the periphery of the guide piece and the inner wall of the second mounting cavity, and communicates with the impeller cavity; water leakage ports are formed in the shell around the guide cavity; a rotatable impeller is arranged in the impeller cavity, and is connected with a rotating shaft; and the lower end of the rotating shaft penetrates through theguide piece to form a torsion output end. The cleaning device can move in pipes for cleaning; the source of working power of the whole cleaning device depends on impact force of water currents introduced into the cleaning device, so that the power source of the cleaning device is more energy-saved and environment-friendly; and the cleaning device cleans in pipes fully filled with water, and realizes high-quality cleaning of the inner walls of the pipes.

Description

technical field [0001] The invention relates to a cleaning device for the inner wall of a steel pipe. Background technique [0002] The degreasing process in the production process of stainless steel pipe is generally carried out before the heat treatment or inspection process to prepare for the heat treatment and inspection process of the steel pipe. The degreasing process is one of the important processes in the stainless steel pipe production process. In the production of stainless steel pipes, if the degreasing process is not in place, the steel pipes with lubricant oil on the surface enter the bright continuous treatment furnace for heat treatment, which will lead to the following two results: (1) The surface of the stainless steel pipe after heat treatment will appear "yin "color" (carburization), which reduces its intergranular corrosion resistance, especially for ultra-low carbon stainless steel pipes; (2) destroys the atmosphere in the furnace for protecting the br...
