[0005] To solve the above problems, the technical solutions adopted by the present invention are an equipment and method for removing oil, rust and scale on the surface of a backup roll bearing housing, including a box body, which is arranged in a pit dug on the ground. Above the ground, a high-pressure washing pump, a cleaning oil tank and a clean oil pump are fixedly installed. The output end of the high-pressure washing pump is connected with a hard pipe and a hose. One end of the hose is connected with a high-pressure water gun, and one end of the hard pipe is connected with a purging pipe structure. The bottom end of the box body is fixed with a roll saddle. A liquid collection tank is arranged near one side below the box body. A grating plate is covered above the liquid collection tank, and a sewage pump is arranged above the grating plate.

[0006] The purging pipe structure includes an inner side nozzle group, a bottom surface nozzle group and an outer side nozzle group. Among them, the roll saddle is located on both sides of the bottom surface nozzle group.

[0007] As a further solution of the present invention: The liquid collection tank is connected with the clean oil pump for collecting the cleaning agent for recycling use. The output end of the clean oil pump is connected with a sewage pipe for treating the scrapped cleaning agent.

[0008] As a further solution of the present invention: A bearing housing is placed above each of the pair of roll saddles. A backup roll is arranged between the two bearing housings. The bearing housing is hoisted into the box body by a hook and a lifting tool.

[0009] As a further solution of the present invention: Ladders are vertically fixed near both ends on one side of the box body for going up and down to wash the box 1 to handle various problems. A water baffle is fixed at the top end of the box body for preventing the cleaning agent sprayed by the nozzles of the bottom surface nozzle group and the inner side nozzle group from splashing outside the box 1.

[0010] As a further solution of the present invention: the height of the roll saddle is greater than the height of the bottom nozzle group.

[0011] As a further solution of the present invention: the high-pressure flushing pump, the cleaning oil tank, the oil purifying pump, and the sewage pump are all electrically connected to an external power supply. The high-pressure flushing pump is selected as an industrial high-pressure cleaning machine with 380V / 20KW / 400KG. The structure of the cleaning oil tank is a steel structure box with a cover of 1M*1M*1M. The oil purifying pump is selected as a centrifugal oil purifier CNEM-M1-22, and the sewage pump is selected as an inclined plate sedimentation tank lift pump 50YW20-19-4 / 2P.

[0012] The advantages of the present invention compared with the prior art are as follows: this product is safe and reliable, can avoid safety accidents during high-altitude operations of personnel, and uses mechanical descaling with low labor intensity; it can achieve full coverage, thorough cleaning, simple operation, and can be operated by general employees. It is a closed operation, dust-free, and will not affect the cleanliness of the surrounding area. BRIEF DESCRIPTION OF THE DRAWINGS
