High-pressure water-jet sand blasting cleaning device for inner wall of pipe fitting

Abstract

The invention discloses a high-pressure water-jet sand blasting cleaning device, which comprises an abrasive tank stand, a collection chamber, a tightening and limiting mechanism, an abrasive tank anda pipe fitting jetting device, wherein the abrasive tank is mounted on the abrasive tank stand; the pipe fitting jetting device is mounted on the abrasive tank stand; one end of the pipe fitting jetting device is connected with the abrasive tank, and the other end of the pipe fitting jetting device is hermetically connected with one end of the pipe fitting in a sleeving manner, so as to perform sand blasting cleaning on the inner wall of the pipe fitting; the other end of the pipe fitting is connected with the collection chamber and is axially limited through the tightening and limiting mechanism. The high-pressure water-jet sand blasting cleaning device disclosed by the invention is simple in structure and compact in design and can automatically complete material feeding, material loading, tightening, clamping, sand blasting cleaning, material discharging, collection and the like of the pipe fitting; the cleaning process is fully automatic; the high-pressure water-jet sand blasting cleaning device is easy to operate and convenient to use.

Description

technical field [0001] The invention relates to the technical field of sandblasting cleaning equipment, in particular to a high-pressure water jet sandblasting cleaning device for inner walls of pipe fittings. Background technique [0002] A layer of dense and thick oxide scales will be formed on the inner surface of the hollow pipe after heat treatment, and the surface oxide scales need to be removed before the finished varnish leaves the factory. The traditional descaling cleaning method is shot blasting. This process will generate a lot of dust and noise during descaling, which will pollute the environment and endanger the health of operators. Moreover, when cleaning pipes with relatively small inner diameters (such as drill rods), because the inner wall diameter is too small, the nozzle cannot directly penetrate into the inner wall to clean the inner wall; at the same time, for pipes with large changes in diameter, length and shape, currently, There is still no automati...

Problems solved by technology

The traditional descaling cleaning method is shot blasting. This process will generate a lot of dust and noise during descaling, which will pollute the environment and endanger the health of operators.

Moreover, when cleaning pipes with relatively small inner diameters (such as drill rods), the nozzle cannot directly penetrate into the inner wall to clean the inner wall due to the small diameter of the inner wall; at the same time, for pipes with large changes in diameter, length and shape, currently, There is no automatic, green and environmentally friendly descaling technology and equipment that can clean the inner wall of drill rods of different specifications
