Grate slit structure for ground cement grate plate

Abstract

The invention provides a grate slit structure for a ground cement grate plate and discloses a grate slit structure for reducing wear and resistance through direct contact of long-side straight rolls,short-side arc rolls and auxiliary grate plates and ensuring the anti-blocking effect of the grate plate. The grate slit structure is characterized in that main grate plates are provided with grate slits, and the grate slits are rectangular slits; the two ends of each grate slit are provided with avoidance grooves, the inner wall of each avoidance groove protrudes to form an arc scraping edge, each arc scraping edge is provided with clamping teeth, and two short-side arcs are arranged in the two avoidance grooves correspondingly; the diameter of each short-side arc roll gradually increases from the middle to the two ends; the circumference of each short-side arc roll is circumferentially provided with arc sliding grooves; arc sliding teeth are formed between the arc sliding grooves; the arc sliding teeth are provided with bristles; the two sides of each grate slit are provided with receding grooves, two connecting shafts are arranged in the two receding grooves correspondingly, and theinner walls of the receding grooves are provided with clamping teeth form straight scraping edges; and the long-side straight rolls are sleeved on connecting shafts.

Description

technical field [0001] The invention relates to a grate slit structure used for a cement mill discharge grate plate, which belongs to the field of cement production equipment. In particular, it relates to a grate seam structure through direct contact between long-side straight rollers, short-side arc rollers and auxiliary grate plates to reduce wear and resistance and ensure its anti-clogging effect. Background technique [0002] The cement mill is the key equipment for crushing the material after it is crushed, and the discharge grate is a discharge device for the rotating part of the mill. The gap is small, and there are coarse particles and grinding balls or fragments in the cement mill, which makes the discharge grate easily blocked, resulting in difficult discharge, full grinding, ball paste, etc., along with affecting the output and production of the cement mill. As a result, in the existing device, the clogging phenomenon of the discharge grate plate is reduced by ad...

Problems solved by technology

[0002] The cement mill is the key equipment for crushing the material after it is crushed, and the discharge grate is a discharge device for the rotating part of the mill. The gap is small, and there are coarse particles and grinding balls or fragments in the cement mill, which makes the discharge grate easily blocked, resulting in difficult discharge, full grinding, ball paste, etc., along with affecting the output and production of the cement mill. As a result, in the existing device, the clogging phenomenon of the discharge grate plate is reduced by adopting the vibration method, but because it applies the overall vibration, the force of the vibration force transmitted to the grate seam is relatively small, resulting in a low anti-clogging effect. There will be grate cracks or grate hole clogging

[0003] A kind of grate plate for cement mill designed by the applicant to solve the above problems, including support frame, main grate plate, grate slit, auxiliary grate plate, servo motor, auxiliary inserting plate and other structures, and because the main and auxiliary grate plates are connected to each other Fitted plug-in structure, the auxiliary grate plate directly slides and rubs against the chute between the main grate plate when reciprocating sliding, and the wear will be serious after a period of use, which will easily affect the reciprocating pushing and anti-clogging effect of the grate plate
