Abstract

The invention relates to a sand supply amount control system for post-mixing type high-pressure jet cleaning, and a method thereof. The system comprises: a jetting device; a supplied sand stirring barrel connected with the pipeline of the jetting device, wherein a slurry containing hard abrasive particles and an aqueous medium is arranged in the supplied sand stirring barrel, and the pipeline of the supplied sand stirring barrel is connected with a standby sand box for supplying the hard abrasive particles to the supplied sand stirring barrel; a control device in communication connection with the standby sand box and a weight measuring device arranged at the bottom of the supplied sand stirring barrel respectively; a granularity screening device, a sand-water separation device, a water filtering device and a supercharging device which are connected with the pipeline of the supplied sand stirring barrel, wherein the supercharging device is connected with the jetting device; and a collecting device arranged at the bottom of the jetting device and connected with the sand-water separation device. In the invention, the accurate establishment of the storage amount of the abrasive particles in the whole system is realized through weighing the weight, so the storage amount of a motor required by the circulation in the whole system is accurately controlled, thereby the control of the jetting stability of the jetting system is finally realized.

Description

technical field [0001] The present invention relates to the field of post-mixing jet cleaning. Specifically, the present invention relates to a control system and method for sand supply amount of post-mixing jet cleaning. The control system and method for sand supply amount are mainly used to realize the overall Effectively control the stability of the amount of sand, realize the stable control of the total amount of different types of abrasives in the mixed injection system, ensure that the amount of sand in the system can always maintain the injection system with sufficient and stable mortar sources, and ensure the injection of the injection system The stability of the effect, thereby realizing the strict control of the characteristics of the post-mixing jet, effectively improving the stability of the post-mixing jet cleaning effect, is an invention and creation related to the post-mixing high-pressure jet cleaning technology. Background technique [0002] The mixed jet cl...
