Technical Field

[0001] The utility model relates to the technical field of fire extinguishers, in particular to a fire extinguishing agent raw material batching device. Background Art

[0002] Fire extinguishing agent is a substance or mixture that can be used to extinguish fire when it occurs. Its main function is to suppress the fire and extinguish the fire through cooling, suffocation, isolation, etc., so as to reduce the losses and hazards caused by the fire. Different types of fire extinguishing agents are suitable for different types of fires. Among them, the main raw materials of dry powder fire extinguishing agent include ammonium phosphate, ammonium sulfate, sodium bicarbonate, sodium chloride, mica powder, etc. These raw materials need to be mixed and batched using a batching machine during the batching process.

[0003] However, the current batching equipment used for fire extinguishing agent raw materials has a simple structure and only has a mixing function. The operator needs to use an electronic scale to weigh and proportion each raw material one by one, and can only stir at the same location, resulting in poor mixing effect and low mixing efficiency. Secondly, there are residual raw materials on the surface of the electronic scale, which needs to be cleaned manually, which is time-consuming and labor-intensive, and increases the workload of the operator.

[0004] Therefore, a fire extinguishing agent raw material batching device is proposed to solve the above problems. Utility Model Content
