Movable linear vibrating screen and method special for dry sand making production line

Abstract

The invention relates to a movable linear vibrating screen and a vibratory sand screening movement method special for a dry sand making production line, which can guarantee that a screen in the linear vibrating screen has an exciting sand screening function and also has a trace front-back movement sand screening function. The movable linear vibrating screen comprises an upper movable linear vibrating screen and a lower movable linear vibrating screen with same structures which are distributed up and down and are positioned on an upper linear vibrating screen guide rail and a lower linear vibrating screen guide rail respectively, wherein an exciting motor in the upper movable linear vibrating screen is arranged on the middle part of a screen box; four corners of the back face of the screen box are provided with grooves; the grooves in the four corners of the back face of the screen box are matched with upper end faces of supporting legs through elastic cushions respectively and are used for supporting the screen box; the lower ends of the supporting legs are connected with the upper end faces of I steel bars; the lower ends of the I steel bars are provided with track wheels; the track wheels are positioned on the linear vibrating screen guide rails; an upper layer screen plate assembly and a lower layer screen plate assembly are positioned on the upper part and the lower part on the inner side of the screen box respectively.

Description

technical field [0001] The invention relates to a special mobile linear vibrating screen for a dry-process sand production line, which can make the screen in the linear vibrating screen not only have the function of exciting sand screening, but also have the function of slightly moving back and forth to screen sand, and a moving method for vibrating screen sand. It belongs to the field of dry linear vibrating screen manufacturing. Background technique [0002] CN201070621Y, the name "multi-layer screen vibrating screen", mainly consists of a support, a vibration isolation device, a screen box, a multi-layer screen, a vibrator and a material receiving device, and is characterized in that: at the discharge end of the vibrating screen box , there is a layer of half-cut screen between the upper and lower screens; the width of this screen is equal to that of other screens, and the length is between one-third and two-thirds of the upper screen; the upper screen The mesh openings ...
