Description

Superfine powder recovery container, anti-explosion and flame-retardant device for transport vehicle tank body and special equipment thereof
Technical Field
The invention relates to an explosion-proof flame-retardant device for a recovery container and a transport vehicle tank body of fine powder and special equipment thereof, belonging to the special explosion-proof flame-retardant device for recovering and transporting fine powder such as industrial dust, coal powder, mineral powder and the like in industrial and mining production enterprises and equipment processing and manufacturing industries.
Background

Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects of the existing fine powder recovery container and the existing carrier vehicle tank device, and provides a safe, reliable and efficient fine powder recovery container, a carrier vehicle tank anti-explosion and flame-retardant device and special equipment thereof.
(1) The explosion-proof and flame-retardant device for the micro-fine powder recovery container and the transport vehicle tank and the special equipment thereof have the micro-powder encryption function, and the principle is that high-pressure and high-speed nitrogen flow is adopted to convey the micro-fine powder to the recovery container and the transport vehicle tank. Under the action of high-pressure and high-speed nitrogen flow, the micro-fine powder particles are mutually extruded, the impact shearing action of the nitrogen on the micro-fine powder particles and the impact friction and shearing action of the micro-fine powder and the inner wall of a recovery container or a transport vehicle tank body lead the micro-fine powder to be polymerized into spherical particles with the diameter less than or equal to 0.5mm, thereby leading the micro-fine powder to be polymerized into spherical particles with the diameter less than or equal to 0.15g/cm3Increasing the concentration to 0.5-1.2 g/cm3The device is convenient to recover, package and transport, improves the labor productivity and reduces the transport cost.
(2) In the explosion-proof flame-retardant device of the micro-fine powder recovery container and the transport vehicle tank body, high-speed and high-pressure nitrogen flow is adopted for conveying airflow. The micro-powder is in an oxygen-free state, and combustible and explosive materials such as metal magnesium, calcium, aluminum, zinc and the like in the micro-powder are difficult to form a combustible and explosive working condition; and the micro-fine powder can form a flame-retardant working condition in an oxygen-free state. Under the action of high-speed and high-pressure nitrogen flow, the fine powder is enriched and encrypted, so that the air occupancy is greatly reduced. Therefore, the problems of explosion and spontaneous combustion of the fine powder are effectively solved.
(3) The dust removal cloth bags arranged in the explosion-proof and flame-retardant devices of the fine powder recovery container and the transport vehicle tank body adopt high-pressure nitrogen airflow reverse blowing for the purpose of secondary pollution of fine powder and preventing the dust removal cloth bags from being blocked, and special equipment for the high-pressure nitrogen tank is arranged in the recovery container and the transport vehicle tank body, so that the safety problems of fine powder explosion and spontaneous combustion caused by air reverse blowing are effectively solved. Meanwhile, the problems of insufficient nitrogen supplement and standby are solved.
(4) The micro-fine powder recovery container and the transport vehicle tank body device are internally provided with special directional closed vibration unloading equipment, so that the unloading efficiency is improved, the unloading secondary pollution is avoided, and the like.
By adopting the technical scheme, the explosion-proof flame-retardant device for the fine powder recovery container and the transport vehicle tank body and the special equipment thereof have the following beneficial effects after years of tests and improvement perfection: (1) the loading amount is increased by more than 3 times; (2) the problems of fine powder explosion and spontaneous combustion are fundamentally solved; (3) the labor productivity is improved by more than 85 percent; (4) the transportation cost is reduced; (5) effectively solves the secondary pollution problem of the micro-fine powder and improves the working environment. Therefore, the invention provides a safe, reliable and efficient superfine powder recovery container, an explosion-proof and flame-retardant device for a transport vehicle tank body and special equipment thereof.
