Coarse material discharge opening of spin-vibration screen

Abstract

The invention discloses a coarse material discharge opening of a spin-vibration screen. The coarse material discharge opening comprises a material discharging pipe with a vertically-downward material outlet and is mainly improved in that an open oblique edge is arranged on one side of the horizontal section of the material discharging pipe from a bend end to a screen frame connection end; a outwards-opening gate is arranged rotatably at the open end opening of the material discharging pipe from one side to the other side; the operation rod of the gate is led outwards in a sealing mode from the inside of the material discharging pipe through one side; and a locking device and a fixing screw are arranged the lead-out end of the operation rod. According to the coarse material discharge opening, the horizontal section of the rectangular material discharging pipe is designed to be a cone of which the opening diameter is large in the inner part and small in the outer part, so that emission speed can be greatly improved; and meanwhile, the gate is designed to be of an outwards-opened type instead of an inwards-opened type, so that the coarse material discharge opening has the advantages of visual operation, good sealing performance, working efficiency improvement and environment protection.

Description

technical field [0001] The invention relates to screening equipment, in particular to a coarse material discharge port with fast material discharge speed and good sealing performance, which is suitable for installation on a rotary vibrating screen. Background technique [0002] Existing rotary vibrating sieve coarse material discharge outlets are all equipped with a square hollow right-angle discharge pipe on one side of the screen frame of the rotary vibrating screen facing outward and downward from the screen, and an inner discharge pipe is installed on the side wall of the discharge pipe. Open gate. The main disadvantage of this traditional rotary vibrating sieve coarse material discharge port is that because the diameters at both ends of the right-angled discharge pipe are the same, when the gate is opened to discharge coarse material, the discharge speed is slow, which affects the screening efficiency. In addition, because the gate is The inner opening structure has po...

Problems solved by technology

The main disadvantage of this traditional rotary vibrating screen coarse material discharge port is that, because the two ends of the right-angled discharge pipe have the same caliber, when the gate is opened to discharge the coarse material, the discharge speed is slow, which affects the screening efficiency. In addition, because the gate is Inner open structure, poor sealing performance, easy to leak the vibrating material dust to the outside, affecting the surrounding air
