The invention discloses a hand-operated sand blasting machine with high vacuum recovery efficiency, including a cabinet, a sand storage tank is arranged on the right side of the cabinet, and at least two groups of nozzles are arranged in the cabinet which are connected with the sand storage tank and the high-pressure air source pipeline. A recovery tank is arranged on the right side of the cabinet, and an inverted conical funnel is arranged at the bottom of the cabinet, and the recovery tank is respectively connected with the lower end of the funnel and the sand storage. A pneumatic valve is arranged on the pipeline between the recovery tank and the lower end of the funnel and the sand storage tank. The inlet of the sand storage tank and the recovery tank is sealed and connected with a vacuum pump. A filter screen is arranged at the inlet of the vacuum pump and a back-blowing pipe is connected to release nitrogen through the pulse valve. The pressure of the nitrogen is set at 0.6 MPa to 0.8 MPa. The front side of the cabinet is provided with a glass window, two hand holes are arranged under the glass window, and the edge of the hand hole is provided with a retractable glove, and a pressure gauge and an adjusting knob are arranged above the glass window. Through the vacuum recovery and pneumatic valve opening and closing pipeline, the recovery speed is fast, which greatly improves the recovery efficiency.

一种真空高效回收的手操喷砂机
本专利技术涉及喷砂机
,特别是涉及一种手操喷砂机。
技术介绍
喷砂机是一种表面处理机械,它利用高速喷出的各种规格不同的砂粒对工件进行抛光、去杂质等表面处理。现有的喷砂机的喷枪一般为固定式或手动操作进行移动,辐射范围小,这样会导致产品抛光不全面、不均匀;且目前的喷枪的安装位置不能调节,因此对各种尺寸规格的工件的适应范围不大,且防尘效果不佳,砂料损耗大,利用率较低,成本较高;此外,现有的自动喷砂机不具备手操功能,在进行异形工件的喷砂时较为困难,抛光效果差。为了解决这些问题,本申请人申请号为2017217173581的专利技术专利申请申请了一种可手操的自动喷砂机,并很好的解决了上述问题,但是,在使用中发现其回收速度非常慢,回收效率极低;因此,有必要对该技术专利申请做进一步的改进和优化。
