Closed circulation dust removal device of impact crusher

Abstract

The invention relates to dust removal equipment of a crusher, in particular to a closed circulation dust removal device of an impact crusher. The closed circulation dust removal device of the impact crusher comprises the impact crusher arranged on a base; a material inlet blocking curtain is arranged at a material inlet of the impact crusher; a material outlet of the impact crusher is provided with a material outlet hopper; a conveying belt is arranged below the material outlet hopper; an air inlet is arranged above the material inlet of the impact crusher; an air outlet is arranged at one side of the material outlet hopper; the air outlet is connected with an air suction pipeline; an outlet of the air suction pipeline is connected with a cyclone powder collector; an air inlet of the cyclone powder collector is hermetically connected with the outlet of the air suction pipeline; an air outlet of the cyclone powder collector is connected with a centrifugal fan; an air outlet of the centrifugal fan is connected with an exhaust pipeline; the other end of the exhaust pipeline communicates with the air inlet of the impact crusher; the exhaust pipeline is also connected with an air supplementing pipeline; the other end of the air supplementing pipeline communicates with the air inlet of the cyclone powder collector; and an adjusting air valve is arranged in the air supplement pipeline.

Description

technical field [0001] The invention relates to a dust removal device for a crusher, in particular to a closed-circuit cycle dust removal device for an impact crusher that makes the interior of the impact crusher form a negative pressure state. Background technique [0002] As a crusher that uses the impact principle to crush materials, the impact crusher has the characteristics of simple structure, high reliability, and wide application range, and is widely used in mining, chemical, construction, railway and other industries. [0003] The impact crusher adopts the principle of impact crushing. When the rotor of the main component rotates at high speed, it will generate a large airflow effect. The inside of the equipment will generate a downward exhaust flow from top to bottom, which will mix with the fine powder generated during the crushing process and pass through the discharge. The outlet is discharged into the external environment, causing pollution to the environment a...
