Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing agent filling, and more specifically to a superfine dry powder fire extinguishing agent filling device. Background Art

[0002] Dry powder fire extinguisher is a kind of fire extinguisher. According to the type of dry powder fire extinguishing agent, it can be divided into ordinary dry powder fire extinguisher and ultra-fine dry powder fire extinguisher. According to the moving mode, it can be divided into three types: portable type, backpack type and cart type. The ultra-fine dry powder fire extinguisher needs to use filling equipment to inject the ultra-fine dry powder fire extinguishing agent into the fire extinguisher tank during production.

[0003] After searching, the utility model patent with announcement number CN212347507U discloses a dry powder fire extinguishing agent rapid filling device, including a gantry, a support frame and a conveyor belt. By providing a conveyor belt, when filling, it is only necessary to place the tank body in the placement slot on the conveyor belt, which is convenient for filling. The degree of automation is high, and the filling is carried out on an assembly line, which improves the filling efficiency, thereby improving the filling speed, facilitating rapid filling, and reducing the labor intensity of workers during filling. By providing a first upper limit plate, a second upper limit plate and a first lower limit plate, a second lower limit plate, and all of which are provided with a card slot, when filling, the card slot is used to card the tank body, thereby facilitating the dry powder filling machine to fill the tank body, improving the stability during filling, facilitating use, and increasing the filling speed.

[0004] However, the above patent has the following shortcomings: it can only fix the tank during filling, but not during conveying by the transmission belt; and the inner diameter of the slot on the limit plate is fixed, which is only convenient for fixing the tank with one outer diameter specification, and the practicality is poor. Therefore, we propose a superfine dry powder fire extinguishing agent filling device. Utility Model Content
