Production line equipment and production process of a dry powder fire extinguishing agent

Abstract

The invention provides production assembly line equipment of a dry powder extinguishing agent and a production process of the dry powder extinguishing agent. The production assembly line equipment comprises a rack, dust collectors, heating colters, an oxygen-free heating pipe, a cooling colter, a vibrating sieving machine, a tapered colter and a water tank, wherein the dust collectors, the heating colters, the cooling colter, the vibrating sieving machine and the tapered colter are fixed on the rack from top to bottom in sequence; the dust collectors are connected with the heating colters; cold material inlets are formed in the top parts of the heating colters and the bottom parts of the heating colters are connected with the cooling colter; the bottom of the cooling colter is connected with the vibrating sieving machine; the bottom of the vibrating sieving machine is connected with the tapered colter; the oxygen-free heating pipe is connected with the heating colters so that materials in the heating colter are silicified and dried; and the cooling colter is provided with a cooling water path. According to the production assembly line equipment, the oxygen-free heating pipe is used for heating and carbon is not deposited on the heating pipe and the power consumption amount is low; the property of the tapered colter has no granularity layering phenomenon; circulating cooling and colter agitation commonly solve water condensation phenomenon; and the dust collectors bring away water in a process of sucking the dust and the drying speed is accelerated.

Description

technical field [0001] The invention relates to the field of dry powder fire extinguishing agent, in particular to a production line and process of dry powder fire extinguishing agent. Background technique [0002] Dry powder fire extinguishing agent is a commonly used fire extinguishing material, which is composed of fire extinguishing base material (such as baking soda, ammonium carbonate, ammonium phosphate, etc.), appropriate amount of lubricant (magnesium stearate, mica powder, talcum powder, etc.), a small amount of moisture Agents (silica gel) are mixed and co-ground into fine particles. [0003] In the prior art, there are many problems and shortcomings in the assembly line equipment used to produce dry powder fire extinguishing agent, including at least the following points: [0004] 1. Use electric heating tubes for heating. Since the electric heating tubes are directly in contact with the air, it is easy to generate carbon deposits, resulting in high power consum...

AI Technical Summary

Problems solved by technology

[0004] 1. Use electric heating tubes for heating. Since the electric heating tubes are directly in contact with the air, it is easy to generate carbon deposits, resulting in high power consumption, low efficiency, and slow heating;

[0005] 2. Adopting the traditional process, the produced products have large granularity and stratification;

[0007] 4. Silicification after injection of silicone oil, the drying time takes 3 to 3.5 hours, which takes a long time and consumes a lot of electricity;

[0008] 5. The production capacity of the assembly line equipment is relatively low. Taking the 8-cubic mixing coulter machine as an example, the annual output value is about 6,000 tons
