Abstract

The invention relates to a device and a method for realizing premixed jet flow continuous jetting. The device comprises at least one main tank; at least two sub-tanks connected with an inlet end of the main tank via a pipeline and a high pressure sand valve, respectively; a mortar supply pipeline connected with inlet ends of the sub-tanks via the pipeline and a low pressure sand valve; at least three sets of weight measurers arranged at the main tank and sub-tanks, respectively; a water pool or water tank having its outlet pipeline arranged with a filter, a booster pump and a control valve, wherein the filter, booster pump and control valve are connected with the main tank and each sub-tank via sub-pipelines, and the sub-pipeline is arranged therein with a high pressure water valve; a sand mixer having its inlet end connected with the water tank and an outlet of the main tank, respectively, and its outlet connected with a nozzle; and a controller electrically connected with the low pressure sand valve, high pressure sand valve and weight measurers, respectively. Through function distribution of the main tank and multiple sub-tanks, the invention realizes sand supply of each sub-tank to the main tank in turn, mortar in the main tank is always maintained in a reasonable range, and the mixing point is arranged at bottom of the main tank, thus, stable, long-time and large-flow mortar supply of premixed jet flow is realized.

Description

technical field [0001] The present invention relates to surface cleaning technology, in particular to a device and method for realizing continuous spraying of pre-mixed jets, which are mainly used to realize long-term stable and continuous spraying ability when performing pre-mixed spraying of liquid water and abrasives. It can significantly improve the use effect of the pre-mixed jet, and directly improve the surface cleaning, drilling and other occasions that require large flow and long-term use, thereby directly improving the working efficiency of the pre-mixed jet. Background technique [0002] In order to effectively clean the corrosion layer (such as rust layer, scale), paint layer, corner processing burr, etc. on the surface of various products, the hybrid jet cleaning technology is usually used. Due to the different forms of jet generation, this hybrid jet cleaning technology has huge differences in cleaning effect and jet stability. [0003] Usually, considering th...
