Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, the high-pressure water jet sandblasting production line for the inner surface of pipes of the present invention includes a high-pressure water generation system, an abrasive supply system, an abrasive circulation system, a water circulation system, a pipe rotation drive mechanism 17, a nozzle 3 and a nozzle moving mechanism. The pipe fittings 2 to be processed are mounted on the pipe rotation driving mechanism 17, and driven by the pipe rotation driving mechanism 17, the pipe fittings 2 rotate. The nozzle 3 and the abrasive supply system are installed on the nozzle moving mechanism together, and the abrasive supply system moves synchronously with the nozzle 3, so that the sand delivery distance is shortened and the sand-water two-phase flow is stable and uniform, compared with the existing high-press...

Abstract

The invention discloses a high-pressure water jet sand-blast cleaning production line for the inner surface of tubing. The high-pressure water jet sand-blast cleaning production line comprises a high-pressure water generating system, an abrasive supplying system, an abrasive circulating system, a water circulating system, a tubing rotating drive mechanism, a nozzle and a nozzle moving mechanism, wherein the input end of the nozzle is communicated with the high-pressure water generating system and the abrasive supplying system, the tubing to be treated is arranged on the tubing rotating drive mechanism, and the nozzle and an abrasive tank in the abrasive supplying system are installed on the nozzle moving mechanism, and the abrasive supplying system synchronously moves along with the movement of the nozzle. The high-pressure water jet sand-blast cleaning production line has the advantages of simple and compact structure, low cost, convenience in operation, good cleaning effect, high efficiency and the like.

Description

technical field [0001] The invention mainly relates to the technical field of high-pressure water jet sand blasting, in particular to a high-pressure water jet sand blast cleaning production line for the inner surface of pipes. Background technique [0002] Pretreatment (paint removal, rust removal and scale removal, etc.) must be carried out before the inner surface of the pipe is sprayed with anticorrosion. Most of the current treatment methods are compressed air sandblasting, inner wall shot blasting and chemical cleaning. Because compressed air sandblasting and inner wall shot blasting will produce a lot of dust, the equipment must be equipped with a corresponding dust removal device, which makes the whole equipment complex and energy-consuming. Once it is not properly treated, it will generate a lot of air pollution. It will also cause environmental pollution. Therefore, some practitioners have proposed the use of high-pressure water blasting cleaning technology. The ...
