Coal yard dust removal environmental protection equipment

Abstract

The invention discloses coal yard dust removal environmental protection equipment. The equipment is structurally provided with a machine body, foot stools, a fan, a suction inlet and a dust collectionbox. The equipment has the following beneficial effects that annular displacement is conducted through a second screen ring, an arc ring block moves on the inner side edge of a clean exhaust area todrive the flow direction and flow speed of airflow, a swing door body swings towards an inner groove chamber under the impact force of air pressure, dusty gas can conveniently flow into the inner groove chamber, light-volume particles are absorbed, and then a clamping and inserting plate and a front clamping plate are separated and matched, so that dust particles penetrate through holes of the front clamping plate and the clamping and inserting plate; and the air pressure penetrating force can be enhanced through the through hole edge, a negative pressure bag is conveniently and quickly pressed to deform, then a supporting and guiding block is bent in an arc shape, and the swing door body is bent in a reverse arc shape through the jacking force generated by the back of the supporting and guiding block, so that a certain guiding effect is achieved on the dusty gas, the generated adsorption force towards the inner part of the inner groove chamber is stronger, the negative pressure bag and a mutual force bag interact with each other to enable the swing door body to return to the original shape quickly when the impact force of air flow is reduced, and the swing-back force is enhanced to intercept dust particles in the inner groove chamber.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and more specifically relates to a coal yard dedusting environmental protection equipment. Background technique [0002] A large amount of coal dust will be generated in the production process of coal mines, and flying dust will affect the working environment and personnel health. It usually needs to use dust removal equipment to absorb and capture coal dust. According to the concentration of dust in the air, there are also some in production practice. Various types of dust removal equipment are used for dust removal operations to ensure good air quality. [0003] Based on above-mentioned inventor's discovery, existing coal yard dedusting environmental protection equipment has the following deficiencies: [0004] When the inertial force dust removal equipment is used for coal dust removal, due to the different cohesiveness and hygroscopicity of the dust in the coal dust, the siz...

Problems solved by technology

[0004] When the inertial force dust removal equipment is used for coal dust removal, due to the different cohesiveness and hygroscopicity of the dust in the coal dust, the size and weight of the particles are different. When they are absorbed into the inner cavity of the equipment cylinder, the light dust particles will Due to the small inertial force, it is slower than larger particles to pass through the sieve cavity wall, so that light-volume dust tends to stay in the cavity for a long time, and secondary dust is prone to occur.
