Abstract

The invention discloses a suction-type rotary sand-blasting and powder-spraying device, and belongs to the field of rotary sand-blasting devices. The suction-type rotary sand-blasting and powder-spraying device comprises a rotary sealing base and a suction-type sand-blasting gun. The rotary sealing base is provided with two independent fluid pipelines, wherein one pipeline is designed on the coreof a central tube, so that when a powder-containing and sand-containing two-phase medium flows passes through the rotary central tube, abrasion is minimized, the abrasion-resistant requirement of a structure allowing powder-containing and sand-containing fluid containing solid particles to pass through at a high speed is met, and suction-type rotary sand-blasting and powder spraying is made possible. High-pressure gas rapidly flows through the suction-type sand-blasting gun to form a negative pressure in a sand suction passageway to enable the solid particles to be sucked into the sand-blasting and powder spraying device, and rotary sand-blasting and powder-spraying are achieved by means of reactive force of a jet flow. Compared with an existing sand-blasting machine, the suction-type rotary sand-blasting and powder-spraying device has the advantages that the material spraying range is wide, materials can be dispersed more uniformly, metering is more accurate, the size is small, and operation is more flexible and convenient.

Description

technical field

[0001] The invention relates to a sandblasting and powder spraying device in the field of industrial application, more specifically, to a suction rotary sand blasting and powder spraying device. Background technique

[0002] There are many occasions in the industrial field that require rotary powder spraying and sandblasting to improve the efficiency and quality of sandblasting and powder spraying. For example, the feeding and dosing of various processes in the chemical industry, especially the feeding of dry powder and powder materials, has high requirements for uniformity of dispersion, process stability and process scalability. The convenience of the suction type pneumatic powder spraying is better than that of the press-in type, and the meterability is better than that of the turntable type feeder. However, the existing suction powder spray guns do not have a rotating function, and the uniformity of powder spraying and feeding is relatively poor, so they...
