Description

Technical Field

[0001] The utility model belongs to the field of dust explosion prevention, and particularly relates to a dust explosion prevention ventilation device with a filtering structure. Background Art

[0002] Dust explosion refers to a dust cloud formed by the mixing of combustible dust and air in a confined space. Under the action of an ignition source, the dust-air mixture formed burns rapidly, causing a chemical reaction in which the temperature and pressure rise sharply. Dust explosion-proof ventilation equipment is required to remove the dust in order to avoid dust explosion.

[0003] According to the Chinese patent with the publication number "CN215901207U", a dust explosion-proof ventilation device is disclosed, including a cabinet, casters installed under the cabinet and handrails installed on the side of the cabinet. An air inlet pipe is provided on one side of the cabinet, and an explosion-proof fan is connected to the other side of the cabinet. The air inlet pipe and the air outlet of the explosion-proof fan are installed with bellows. The air inlet pipe is installed with a dust concentration detector. A spray chamber, a dust collecting chamber and a water tank are respectively provided inside the cabinet from top to bottom. There is a Strip holes; the spray chamber is symmetrically provided with a number of guide grooves, in which filter plates are installed, the filter plates include a filter frame and a mesh installed on the filter frame, the filter frame is provided with a slope surface at the contact point with the mesh, the thickness of the filter frame is less than the width of the strip holes, the spray chamber is provided with a nozzle interface, and the nozzle interface is connected with an atomizing nozzle; the dust collecting chamber is hinged with a cabinet door, the dust collecting chamber is installed with a dust collecting box, and an opening is provided above the dust collecting box; a water outlet is provided below the water tank, a water inlet is provided above the water tank, and the water outlet is connected with the atomizing nozzle;

[0004] It can be seen from the above structure that by setting casters and handrails, as well as bellows, the ventilation equipment can realize the mobile function, can perform exhaust treatment in multiple locations, and reduce dust concentration. It can be seen from the above structure that the above structure inhales external air through the air inlet pipe, and then filters it through the filter plate, and discharges the filtered dust through the strip holes. It can be seen from the figure that the strip holes are not connected to the filter plate when they are opened, and there is a space in the middle, which is likely to cause dust to be discharged to the outside of the device through the gap, resulting in poor filtering effect of the device and failure to achieve effective filtration.
