Explosion-proof and flame-retardant device for micropowder recovering containers and transport vehicle tank bodies and special equipment of explosion-proof and flame-retardant device

Abstract

The invention discloses an explosion-proof and flame-retardant device for micropowder recovering containers and transport vehicle tank bodies and special equipment of the explosion-proof and flame-retardant device. The explosion-proof and flame-retardant device and the special equipment of the explosion-proof and flame-retardant device are applicable in industries of micropowder recovering, packaging, transportation and the like of various organic, inorganic and composite materials, the problems that traditional micropowder recovering containers and transport vehicle tank bodies are small in loading capacity, high in transportation cost, inflammable, explosive and slow in unloading, can cause secondary pollution and the like are solved, high-pressure and high-speed nitrogen gas flows are used for conveying the materials, a back-flushing dust removal bag, a directional vibration unloading device and a high-pressure nitrogen tank are adopted, and the problems about micropowder compaction, explosion prevention, flame retardancy, timed back flushing, directional vibration unloading, closed conveying, recovering, packaging and the like are solved effectively.

Description

technical field [0001] The fine powder recovery container, transport vehicle tank explosion-proof flame retardant device and special equipment thereof according to the present invention belong to industrial dust, coal powder, ore powder and other fine powder recovery and transportation in industrial and mining production enterprises and equipment processing and manufacturing industries Special explosion-proof flame retardant device. Background technique [0002] The existing fine powder recovery container and the device of the transport vehicle tank have the following problems: (1) the fine powder is in a floating state in the recovery container and the transport vehicle tank, with light bulk density and small loading capacity, resulting in low utilization of the recovery container , the transportation cost is high; (2) the recovery container of the fine powder and the tank body of the transport vehicle are filled with air containing a large amount of oxygen. Since the fine ...

AI Technical Summary

Problems solved by technology

[0002] The existing fine powder recovery container and the device of the transport vehicle tank have the following problems: (1) the fine powder is in a floating state in the recovery container and the transport vehicle tank, with light bulk density and small loading capacity, resulting in low utilization of the recovery container , the transportation cost is high; (2) the recovery container of the fine powder and the tank body of the transport vehicle are filled with air containing a large amount of oxygen. Since the fine powder particles are in a state of floating motion, collide and rub against each other, some fine powder contains a large amount of metal magnesium, Calcium, aluminum, zinc and other flammable and explosive fine powders often cause dust explosion safety accidents, causing casualties and equipment damage; there are also fine particles that collide and rub against each other to generate heat, which is prone to spontaneous combustion, resulting in safety accidents and fine powder burning. (3) Because the fine powder is easy to block the filter device, its blowback device adopts high-pressure air, which is also very easy to cause a safety accident of the spontaneous combustion of the fine powder; (4) the fine powder has a large specific surface area, strong adsorption capacity, and difficult discharge. affect labor productivity
