Description

Technical Field

[0001] The utility model relates to the field of cleaning devices, in particular to a device for cleaning loose powder at the bottle mouth of a dry powder fire extinguisher. Background Art

[0002] A dry powder fire extinguisher is a common fire extinguishing tool, mainly used to extinguish initial fires of flammable and combustible liquids, gases and electrical equipment. It achieves the fire extinguishing effect by spraying dry powder fire extinguishing agents. These dry powder fire extinguishing agents are fine solid powders made by drying, crushing and mixing inorganic salts with fire extinguishing efficiency and a small amount of additives. The fire extinguishing agent in the dry powder fire extinguisher is valid for five years at room temperature, but generally speaking, the powder in the dry powder fire extinguisher needs to be refilled every one or two years. The refilling of existing dry powder fire extinguishers is mostly operated by automatic dry powder filling machines. When in use, the operator only needs to insert the feed pipe into the empty can, and then use an electronic scale to feed a fixed amount of dry powder into the empty can. The operation process is simple and convenient.

[0003] After filling the existing dry powder fire extinguisher with dry powder, the feed pipe needs to be pulled out of the tank. During the extraction process, the feed pipe can easily bring the dry powder out of the tank, causing the dry powder to spill on the bottle mouth and the surface of the filling table, which means that the dry powder fire extinguishing agent is wasted. At the same time, the scattered dry powder may drift into the working environment, causing a certain impact on the air quality and even posing a threat to the respiratory health of the workers. In addition, if the loose powder accumulates for a long time, it may also cause pollution to the storage area.

[0004] Therefore, for the above-mentioned existing dry powder fire extinguishers, after filling with dry powder, the feed pipe needs to be pulled out of the tank. During this process, the dry powder is easily brought out of the tank, resulting in a waste of dry powder raw materials and a threat to the respiratory health of the staff. A powder cleaning device for the bottle mouth of a dry powder fire extinguisher filling can be designed to clean up the fallen dry powder in time to avoid wasting dry powder raw materials and affecting the health of the staff. Utility Model Content
