Band type linear vibrating screen

Abstract

The invention relates to a vibrating screen, in particular to a band type linear vibrating screen. The band type linear vibrating screen comprises a base, a screen body, a lower flow guide chute and a feeding box, wherein the screen body is installed on the base through a supporting spring, the lower flow guiding chute is installed on the base and located below the screen body, and the feeding box is installed on the base and located at one end of the screen body. According to the band type linear vibrating screen, the screen body makes linear motion under the exciting force of a vibration exciting motor, band type screen cloth makes circulating transporting motion under the driving of a transmission motor, material separation and material transportation are independent of each other, the exciting force is adjusted by changing the mass of an eccentric block of the vibration exciting motor or eccentric distance, and the material transporting speed is adjusted by changing the rotating speed of the transmission motor. The problem of an existing linear vibrating screen that the completeness of solid-liquid separation and screen speed contradict each other and can not be considered at the same time is solved.

Description

technical field [0001] The invention relates to a vibrating screen, in particular to a belt type linear vibrating screen. Background technique [0002] In the process of oil drilling, after the mud brings the cuttings back to the ground, it needs to pass through a series of solid-liquid separation equipment so that it can be recycled, and the drilling shale shaker is one of the key equipment. When the drilling shale shaker is working, the exciting force generated by the exciting motor has a component force in the horizontal direction and vertical direction, and the force in the vertical direction throws the solid phase off the screen surface, so that the liquid phase can smoothly pass through the screen holes. The purpose of screening is achieved, and the force in the horizontal direction promotes the solid phase particles to be thrown off the screen surface to produce a forward displacement, so that the solid phase particles are gradually transported out of the screen. The...
