Example Embodiment

[0008] The embodiment is described in detail in conjunction with the accompanying drawings. The present invention is an improvement to the prior art. It includes a discharge pipe 1 with the outlet at a right angle downward. The hypotenuse 7 that is open to the connecting end of the screen frame is rotated from one side to the other in the open port of the discharge pipe, and an outward-opening gate 3 is installed, and the operating rod 4 of the gate is outward from the discharge pipe through one side. The sealing is drawn out, and the upper end of the operating rod is equipped with a locking device 6 and a fixed screw rod 5 . A sealing rubber layer 2 is provided on the contact surface between the gate and the screen frame. After the above improvements, the inlet of the discharge pipe can be doubled, which can effectively increase the discharge speed and improve the screening efficiency. The gate is opened from the inside to the outside, which can effectively improve the sealin...

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...
