Abstract

The invention discloses a dry powder grinding and screening device for fire extinguishers, which comprises a machine case, a driving motor, a first cam, a base grinding head, a cylinder, grinding rollers and a screening box. The center position is installed with a grinding shaft through bearing rotation, and the lower end of the grinding shaft is connected with a grinding head, and a sieve plate is installed horizontally inside the cabinet, and a grinding roller is installed on the other end of the piston rod of the cylinder; A screening box is installed. The invention has a novel structure, and the grinding head alternately rotates clockwise and counterclockwise during preliminary grinding, thereby improving the grinding effect of the dry powder and preventing the dry powder from being blocked in the gap between the grinding head and the preliminary grinding chamber; and the device Set primary grinding and secondary grinding, so as to effectively improve the effect of dry powder grinding and make the particles of dry powder finer.

Description

technical field [0001] The invention relates to a grinding and screening device, in particular to a dry powder grinding and screening device for fire extinguishers. Background technique [0002] The dry powder fire extinguisher is filled with ammonium phosphate dry powder fire extinguishing agent. Dry powder fire extinguishers can be divided into ordinary dry powder fire extinguishers and ultra-fine dry powder fire extinguishers according to the type of dry powder fire extinguishing agent filled. When making a dry powder fire extinguisher, the raw materials need to be ground into fine powder. The finer the dry powder, the better the quality of the dry powder fire extinguisher. However, the dry powder production equipment for dry powder fire extinguishers on the market is difficult to meet this point. Contents of the invention [0003] The object of the present invention is to provide a dry powder grinding and screening device for fire extinguishers to solve the problems r...
