Linear vibrating screen underneath type dust removal system and method

Abstract

The invention relates to a linear vibrating screen underneath type dust removal system and a linear vibrating screen underneath type dust removal method. The linear vibrating screen underneath type dust removal system and the linear vibrating screen underneath type dust removal method not only an achieve dustless discharge during the sand screening process, but also can reduce electric energy used in a background technology by about 50%. The linear vibrating screen underneath type dust removal system comprises a fixed type linear vibrating screen, wherein one layer or multiple layers of movable type vibrating linear screens are arranged below the fixed type linear vibrating screen, a seal cover covers the periphery of a discharge hole of the fixed type linear vibrating screen and the multiple layers of the movable type vibrating linear screens, and a negative pressure dust suction port is located on the discharge hole of the fixed type linear vibrating screen, and communicated with the movable type vibrating linear screen on the upper layer of the multiple layers of the movable type vibrating linear screens through the seal cover. The linear vibrating screen underneath type dust removal system and the linear vibrating screen underneath type dust removal method have the advantages of 1) needing no wind to blow sand, being capable of completely sucking mixed dust screened out by the fixed type linear vibrating screen, preventing the dust and the sand from being mixed, and obtaining pure sand; 2) being low in energy consumption, and then saving energy due to the fact that sucked material of a cyclone dust collector is the dust low in weight; 3) guaranteeing that cleaning gas is discharged through an exhaust pipe of a pulse bag type dust collector.

Description

technical field [0001] The invention relates to a dust removal system and a dust removal method under a linear vibrating screen, which can not only realize dust-free discharge during the sand screening process, but also reduce electric energy by about 50% compared with the background technology in a dry sand production line, which belongs to the dry method. Sand production line dust removal system manufacturing field. Background technique [0002] CN103433108A, titled "a dry sand making equipment and process", including jaw crusher, impact crusher, first grading screen, dry sand making machine, second grading sieve and centralized dust collection system; the production process route is, stone The stone in the warehouse is evenly sent to the jaw crusher through the feeder for the first coarse crushing, and the crushed material is transported to the impact crusher for the second fine crushing, and the crushed material enters the first classifying screen for further crushing. ...

AI Technical Summary

Problems solved by technology

Its disadvantages: First, due to the open structure of the production line, each process needs to be equipped with a dust removal system, and the energy consumption is high, the dust collection effect is poor, and the dust content in the classified and screened sand is high; the second is that it cannot be realized Clean emission
