2results about How to "Reduce physical hazards" patented technology

A powder material receiving device includes a feeding device, a transfer cylinder, an adjustment assembly, a receiving plate mounted on the adjustment assembly, a first connecting pipe connecting the transfer cylinder and the feeding device, a second connecting pipe connecting the transfer cylinder and the receiving plate, a support base located below the receiving plate, a transfer tank, a pulse gas generator, and an air pump. The transfer cylinder is equipped with a nozzle and a valve interface. The transfer tank includes a tank body and a breather filter for internal pressure regulation. After receiving the material, before the receiving plate detaches from the transfer tank, the external pulse gas generator injects high-pressure pulse gas into the transfer cylinder through the nozzle. After the pulse gas stops, the external air pump extracts the powder-containing gas from the transfer cylinder, the first connecting pipe, the second connecting pipe, and the space above the tank body through the valve interface. This powder material receiving device effectively improves the working environment, reduces the health hazards to workers during powder material transfer, and increases transfer efficiency, thereby increasing the economic efficiency of enterprises.

This utility model relates to the field of dust treatment technology for inkstone carving, and discloses a dust collection and treatment device for inkstone carving, including a workbench and a dust collector. A through hole is provided on the surface of the workbench, and a guide hopper is installed under the workbench surface. A double-pipe is connected to the bottom of the guide hopper. A limit sleeve is installed on the rear wall of the workbench, with bolts connected to its front side. A limit rod, which is slidably fitted inside the limit sleeve, can have its height and angle fixed by tightening the bolts. A support plate is installed on the top of the limit rod, and a dust collector is installed at the front end of the support plate. A lampshade is installed under the dust collector, and a light is installed under the lampshade to provide illumination. A telescopic pipe is connected to the top of the dust collector, and its other end is connected to one of the two ends of the double-pipe. When carving inkstone, the dust collector is activated, and dust is drawn through the guide hopper and dust collector connected to the two ends of the double-pipe. Flying dust is drawn into the dust collection bag through the gap between the dust collector and the lampshade. Dust settling on the workbench surface falls into the guide hopper through the through hole, is guided by the guide hopper, and is then drawn into the dust collection bag by the double-pipe.
