Remote-delivery bladeless ventilating system used in gunpowder and explosive field

Abstract

The invention discloses a remote-delivery bladeless ventilating system used in the gunpowder and explosive field. By the adoption of the remote-delivery bladeless ventilating system used in the gunpowder and explosive field, the problem that explosion risks are caused easily in an existing ventilating system due to friction and collision between gunpowder and explosive dust or gunpowder and explosive particles at a rotary bearing and an impeller in the gunpowder and explosive field is solved. The remote-delivery bladeless ventilating system comprises an air source (1), an air storage tank (2), an air pipe (3), a one-way valve (4), a throttling valve (5) and a ventilating frame (6). The air source (1), the air storage tank (2), the one-way valve (4), the throttling valve (5) and the ventilating frame (6) are connected in sequence through the air pipe (3). The air source (1) and the air storage tank (2) are installed in safe places in a gunpowder-free and explosive-free environment. The ventilating frame (6) is installed in a dangerous place in a gunpowder and explosive environment. The remote-delivery bladeless ventilating system is simple in structure and low in energy consumption, and friction and collision between the gunpowder and explosive powder or particles and movement components in the ventilating system in the dangerous place in the gunpowder and explosive field can be avoided.

Description

technical field [0001] The present invention relates to a ventilation system, in particular to a ventilation system suitable for dangerous places in the production and manufacture of explosives, which includes a gas source, a gas storage tank, a one-way valve, a throttle valve and a ventilation frame connected in sequence through a gas pipe. Background technique [0002] Strict ventilation requirements are involved in the processing and storage of explosive materials and products. On the one hand, dangerous materials such as organic solvents and explosive dust will be permeated in explosive production workshops and warehouses, which will not only cause serious harm to the health of operators. Injuries will also cause explosion accidents after accumulating to the explosion limit; on the other hand, during the production and storage of explosives, heat will be generated due to friction or decomposition. It will aggravate the decomposition of explosive products, so the heat in ...

Problems solved by technology

However, when the bladeless fan is used in a place containing dangerous dust and particles such as explosives, because its air inlet is still in a dangerous environment, the dangerous dust and particles will still come into contact with moving parts such as blades and bearings through the air inlet, which has the advantages of The possibility of deflagration limits the function of the bladeless fan, which also limits its "bladeless" advantage for ventilation systems in the field of explosives

At the same time, the bladeless fans involved in the current literature are mainly desktop fans, and there are no wall-mounted fans used in ventilation systems, and the flow path is long, and the movement direction of the airflow from the air inlet to the air outlet changes more than "180°". much loss

[0005] In summary, the current ventilation systems used in the field of propellants and explosives mainly have the following problems: 1) In the traditional ventilation system, explosive dust or particles enter the rotating bearings of the moving components of the ventilation system or collide with the rotating blades in the ventilation system to generate sparks or explosions; 2) ) The new leafless ventilation system suitable for explosives ventilation system has not yet appeared; 3) It is difficult to clean the ventilation system in the explosives field
