Problems solved by technology

[0004] However, in the prior art, after the solution in the reaction kettle is left to settle, the drain hole is opened to filter the precipitate and collect the foam fire extinguishing agent, but the side wall of the reaction kettle is easy to adhere to more sediment, and the sediment absorbs part of the fire extinguishing agent, causing the kettle Residue of fire extinguishing agent in the body, while increasing the cleaning work of the reactor, affects the ratio accuracy of raw materials when the reactor is repeatedly produced

Embodiment 1

[0035] Such as Figure 1 to Figure 3 As shown, a kind of foam fire extinguishing agent described in the embodiment of the present invention consists of the following weight components: 3-5 parts of perfluorooctyl quaternary ammonium iodide, 2-3 parts of urea, 15-20 parts of blowing agent, 8-10 parts of sodium lauryl sulfate, 4-6 parts of catalyst, 12-15 parts of buffer, 45-50 parts of water, 3-6 parts of ethylene glycol.

[0036] A kind of manufacture method of foam fire extinguishing agent, this method is used to manufacture above-mentioned foam fire extinguishing agent, comprises the following steps:

[0037] S1. Add perfluorooctyl quaternary ammonium iodide, sodium lauryl sulfate, buffer and ethylene glycol into the reaction kettle in sequence, and finally add 20 parts of water, and the stirring unit is driven by the stirring motor 11 to process the raw materials. stir;

[0038] S2. Add the foaming agent, buffer and catalyst of the corresponding components to the reactor,...

Embodiment 2

[0049] Such as Figure 7 As shown in Comparative Example 1, another embodiment of the present invention is: the round hole 2 is provided with a semi-circular water guide groove 5 near the upper position, and the inner walls of the water guide groove 5 near both ends are fixed by elastic ropes 51 There is a small ball 52; the water guide groove 5 is connected with a group of arc holes 53 close to the side of the sharp corner 19, and the end of the arc hole 53 close to the side wall of the sharp corner 19 is inclined downward; after the sliding rod 22 slides, the spray hole is driven 26 moves to the corresponding position of the circular hole 2, and then the water jetted from the spray hole 26 near the upper part passes through the water guide groove 5 and then jets out from the arc-shaped hole 53, further reducing the sediment accumulated between the adjacent scrapers 18, ensuring scraping The smooth closing of the plate 18 and the impact of the water flow on the small ball 52 ...

Abstract

The invention belongs to the technical field of fire extinguishing agents, and particularly relates to a foam fire extinguishing agent and a manufacturing method thereof.The manufacturing method comprises the following steps that S1, perfluorooctyl quaternary ammonium iodide, lauryl sodium sulfate, a buffering agent and ethylene glycol are sequentially added into a reaction kettle according to the proportion, finally, 20 parts of water is added, and a stirring motor (11) drives a stirring unit to stir raw materials; s2, adding a foaming agent, a buffering agent and a catalyst of corresponding components into the reaction kettle, heating and stirring the mixture, adding water of the rest components after the mixture is uniformly stirred, and stirring until the mixture is completely dissolved in the water; s3, the acid-base value of the mixed liquid is adjusted to be neutral, after sedimentation, an air cylinder (15) is matched to push a scraping plate (18) to clean the inner wall of the reaction kettle, reactants are layered and gradually filtered through liquid drainage holes (12), and the foam extinguishing agent can be obtained. And the cylinder scraper moves downwards to scrape residual precipitates on the inner wall of the kettle body, so that the collection efficiency of the fire extinguishing agent is improved, and residual impurities on the inner wall of the kettle body are reduced.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing agents, in particular to a foam fire extinguishing agent and a manufacturing method thereof. Background technique [0002] Foam fire extinguisher, the principle of fire extinguishing is that when extinguishing a fire, it can spray a large amount of carbon dioxide and foam, which can adhere to the combustibles, isolate the combustibles from the air, and achieve the purpose of extinguishing the fire. Foam fire extinguishers are divided into: portable foam fire extinguishers, cart-type foam fire extinguishers and air-type foam fire extinguishers. [0003] A Chinese patent with the publication number CN108853862A discloses an environment-friendly aqueous film-forming foam fire extinguishing agent and a preparation method thereof. The fire extinguishing agent includes in parts by weight: 5-10 parts of water-soluble ammonium polyphosphate, 5-10 parts of urea, 0.5-1 part of xanthan gum, 2-10 ...
