Sand blasting circulation system

Abstract

The invention discloses a sand blasting circulation system which comprises a sand blasting machine, a collecting tank, a material suction machine, a vibrating screen for filtering and an abrasive material hopper. The collecting tank, the material suction machine, the vibrating screen and the abrasive material hopper are sequentially communicated through pipelines. A sand cylinder of the sand blasting machine comprises a first cylinder body, a second cylinder body and an air inlet channel. When a main air inlet pipe is communicated with a first air inlet pipe, a first discharging channel spraysmaterials, and a second feeding channel feeds materials. When the main air inlet pipe is communicated with a second air inlet pipe, a second discharging channel sprays materials, and a first feedingchannel feeds materials. According to the scheme, an abrasive material can be recycled in time after being used, the treated abrasive material can be put into the sand cylinder again to be recycled bycombining the design of the sand cylinder with double cylinder bodies, meanwhile, the material spraying process and the material filling process are conducted through the two cylinder bodies at the same time, and when the abrasive material in one cylinder body is about to be used up, the processes conducted by the two cylinder bodies are interchanged, so that uninterrupted circulation of materialspraying and material filling is realized.

Description

technical field [0001] The invention belongs to the technical field of sandblasting systems, in particular to a sandblasting circulation system. Background technique [0002] The sand blasting machine is powered by compressed air, through the negative pressure formed in the spray gun by the high-speed movement of the air flow, the abrasive is sucked into the spray gun through the sand delivery pipe and ejected through the nozzle, and sprayed onto the surface to be processed. Due to the impact and cutting effect of the abrasive on the surface of the workpiece, after being sprayed on the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved, and the fatigue resistance of the workpiece is improved. It increases the adhesion between it and the coating, prolongs the durability of the coating film, is also conducive to the leveling and decoration of ...

AI Technical Summary

Problems solved by technology

[0003] However, there are many problems in the existing sandblasting machines. Among them, the abrasive reserves of the sand blasting machine are limited. When it is applied to a larger workpiece, it needs to be stopped several times to add abrasives in the sand cylinder to complete the work process. And this also greatly affects the work efficiency

Moreover, after the abrasive is applied to the surface of the workpiece, the abrasive mixed with the impurities falling from the workpiece cannot be returned to the sand tank for direct use, and the abrasive becomes a disposable item. Therefore, when processing a larger workpiece, the traditional sandblasting machine needs to prepare more Impurity-free abrasives will cause huge cost burden and waste of data in the long run
