Independent negative-pressure exhaust gas dust removal device

Abstract

The invention discloses an independent negative-pressure exhaust gas dust removal device, and relates to the technical field of indoor exhaust gas dust removal. The device comprises an equipment body,a supporting steel frame, a plurality of dust baffles arranged on the side wall of the supporting steel frame and a sealing door arranged on the side wall of one dust baffle in a sliding mode. An access hole is formed in the side wall, located on the sealing door, of the corresponding dust baffle. Connecting assemblies which are used for fixing the dust baffles are arranged the supporting steel frame, the supporting steel frame and the multiple dust baffles are combined to form a dust cover which is used for covering the equipment body, and a dust pumping mechanism which is used for pumping out dust and the harmful gas inside the dust cover is arranged on the dust cover. According to the independent negative-pressure exhaust gas dust removal device, the nearby region of the equipment bodyis defined to form an independent space, and therefore the dust and the harmful gas generated by the equipment body can be independently pumped, the energy is effectively saved, and the dust removalefficiency is high.

Description

technical field [0001] The present application relates to the technical field of indoor exhaust and dust removal, in particular to an independent negative pressure exhaust and dust removal device. Background technique [0002] A large amount of dust and harmful gas will be generated in the production workshops of painting, stone processing, metal grinding, furniture grinding, ink printing and other industries. Once the dust and harmful gas are inhaled into the nasal cavity, it will pose a threat to the health of the operator. , so it is necessary to install dust removal equipment in the production workshop. [0003] The existing Chinese patent with the notification number CN209441023U discloses a high-efficiency dust-removing dust removal device for a four-color printing machine, including a printing machine body, which includes four color printers arranged in sequence. There is a conveyor belt between them, and it also includes a dust removal pipe. One end of the dust remo...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there are the following defects: the printing machine uses a turbo fan, a dust removal pipeline and a horn cover to remove dust and harmful gases under negative pressure. There is a certain space, the dust removal area is limited, and the dust is easy to float from the surroundings to the environment. In order to ensure the dust removal effect, the turbo fan has to maintain a high wind speed to absorb more dust, and the energy consumption is high.
