Ventilation device for production workshop

Abstract

The invention discloses a ventilation device for a production workshop. The ventilation device comprises a first ventilation shell and a net surface filter plate; a second ventilation shell is arranged at one end of the first ventilation shell, and connecting fasteners distributed at equal intervals are mounted at the joint of the second ventilation shell and the first ventilation shell; a fan is mounted in the second ventilation shell; and the net surface filter plate is mounted in the first ventilation shell, an activated carbon filter plate is mounted on one side of the net surface filter plate, limiting piles are arranged on the upper side and the lower side of the activated carbon filter plate and the upper side and the lower side of the net surface filter plate, and mounting grooves are formed in the limiting piles. Compared with an existing device, the ventilation device for the production workshop has the advantages that entering gas can be filtered through the net surface filter plate of a hollowed-out net structure, particulate matter in the gas can be removed, the activated carbon filter plate can adsorb tiny dust and toxic substances in the gas, and therefore the gas can be filtered and purified through the net surface filter plate and the activated carbon filter plate before entering the workshop.

Description

technical field [0001] The invention relates to the technical field of ventilation devices, in particular to a ventilation device for a production workshop. Background technique [0002] The production workshop refers to the place where certain processes are completed according to the requirements of the production process or certain products are produced independently. There are usually a large number of people in the production workshop, and some special production processes will produce pollutants. It is necessary to ventilate the workshop at all times. To ensure its air quality, ventilation devices for production workshops are used. [0003] Existing ventilation devices for production workshops can only achieve the effect of ventilation. When the device is ventilating, external dust and impurities in the air are often brought into the production workshop, thus affecting the air quality in the workshop. For this reason, we A ventilation device for production workshop is ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of ventilation device for production workshop, to solve the above-mentioned background technology, because the existing ventilation device for production workshop can only play the effect of ventilation, when the device is ventilated, the external dust and air are often The impurities in the air are brought into the production workshop, which affects the air quality in the workshop
