Abstract

The invention relates to a sand washing machine which comprises a control circuit A, a high-pressure water pipeline B and a compressed air channel C. The control circuit A is used for controlling theopening-closing states of the compressed air channel C and the high-pressure water pipeline B, and comprises a switching-on state and a switching-off state of a control switch at the tail end of a sand blasting pipe. When the control switch at the tail end of the sand blasting pipe is switched on, a pneumatic operated opening of a two-position five-way pneumatic operated directional valve is subjected to ventilation switchover, a control opening of a regulating valve is connected with compressed air, and at the moment, the normally closed state of the regulating valve is converted into the opened state, and the compressed air channel C is opened; an opening of a pneumatic ball valve is connected with compressed air, and the high-pressure water pipeline B is opened; the control switch at the tail end of the sand blasting pipe is closed, the two-position five-way pneumatic operated directional valve resets, the regulating valve is not connected with control air pressure, and is in the normally closed state, and the compressed air channel C is closed; and a close opening of the pneumatic ball valve is connected with compressed air, and the high-pressure water pipeline B is closed. According to the sand washing machine, by introducing a medium and adding water, dust is suppressed, and moreover, the structure is simple, sand blasting and pipe cleaning are facilitated, and the efficiency is high.

Description

technical field [0001] The invention relates to a water-sand machine, in particular to a water-sand machine with simple structure, convenient sand blasting, pipe cleaning and high efficiency. Background technique [0002] Existing dry sandblasting equipment has high dust, pollutes the environment, affects the operator's vision and health, consumes a lot of abrasives, and cannot be used in explosion-proof occasions. Contents of the invention [0003] In view of the above problems, the main purpose of the present invention is to provide a water sand machine with simple structure, convenient sand blasting and pipe cleaning, and high efficiency. [0004] The present invention solves the above-mentioned technical problems through the following technical solutions: a water-sand machine, which includes: a control circuit A, a high-pressure water pipeline B, and a compressed air circuit C; the control circuit A is used for Control the switching status of the compressed air circui...
