Description

Technical Field

[0001] The invention relates to the technical field of fire-proof and extinguishing material production, in particular to a quantitative proportioning and mixing device for preparing fire-proof and extinguishing material additives and a processing method. Background Art

[0002] Fire-proof and extinguishing materials are materials that have the ability to prevent or block the spread of flames. They are used for fire prevention. There are two types: non-combustible materials and flame-retardant materials. Non-combustible materials will not burn; although flame-retardant materials can burn, they are flame-retardant, that is, they are difficult to ignite and carbonize, and the burning will stop after the fire source is removed. Therefore, they are also called flame-retardant materials. A mixing device is required in the production process of fire-proof and extinguishing materials.

[0003] For example, a raw material mixing device for metal materials with convenient quantitative unloading with announcement number CN210964820U includes: an unloading bin and a mixing bin; lower support rods are welded on both sides of the top of the mixing bin, and a fixing ring is welded on the top of the lower support rods; unloading holes are opened at equal angles inside the quantitative disk; a connecting frame is welded on the top of the inner wall of the mixing bin, and a mixing motor is bolted to the middle position of the connecting frame; the lower part of the mixing motor is connected to the mixing rod through a transmission rod; the quantitative unloading position of the three quantitative tubes can be adjusted reciprocally through the quantitative disk with a circular rotating structure, and the real-time telescopic adjustment of the adjusting tube can be coordinated to perform quantitative weighing of raw materials of different weights, thereby realizing the operation effect of quantitative weighing and unloading of metal raw materials in a cyclic manner; however, the mixing rod of the device is fixed in position, and its stirring range is also relatively fixed, so it is difficult for the fire-fighting materials in the local position of the device to be mixed and stirred, resulting in poor mixing effect of the device, low mixing efficiency, and possible obstruction of the mixing process of the fire-fighting materials, resulting in defects in use.

[0004] Therefore, we propose a quantitative proportioning and mixing device and a processing method for preparing fire extinguishing material additives in order to solve the above-mentioned problems. Summary of the invention
