Grate cooler transmission mechanism sealing equipment for cement production

Abstract

The invention discloses grate cooler transmission mechanism sealing equipment for cement production in the technical field of grate coolers. The grate cooler transmission mechanism sealing equipment for cement production comprises a grate cooler transmission shaft and a grate cooler rack, a sealing isolation plate is fixedly connected to the left side of the grate cooler rack, the grate cooler transmission shaft penetrates through the sealing isolation plate, a waterproof sealing bearing is connected to the outer wall of the grate cooler transmission shaft in a sleeving mode, and the grate cooler transmission shaft is fixedly connected with the inner wall of the waterproof sealing bearing. According to the grate cooler transmission mechanism sealing equipment for cement production, the sealing property of a grate cooler transmission mechanism can be improved to a great extent, the condition that dusty gas is blown out to cause secondary pollution on the environment is effectively prevented, and the grate cooler transmission shaft can drive a cleaning brush to brush the outer side wall of the waterproof sealing bearing to prevent dust and impurity adhesion in the rotating process; and the device has the function of washing the outer side wall of the waterproof sealing bearing while brushing is conducted and also achieves the purpose of cooling the waterproof sealing bearing, water spraying treatment can be conducted if high-temperature dusty gas is blown out, and then the pollution degree is reduced.

Description

technical field [0001] The invention relates to the technical field of grate coolers, in particular to a sealing device for a transmission mechanism of a grate cooler for cement production. Background technique [0002] The grate cooler is an important host equipment in the clinker firing system of a cement plant. Its main function is to cool and transport cement clinker; at the same time, it provides hot air for the rotary kiln and calciner, which is the main heat recovery system for the firing system. equipment. Grate cooler is a kind of quench cooler. After the clinker enters the cooler from the kiln, a material layer of a certain thickness is laid on the grate plate, and the cold air blown in passes through the moving material layer on the grate bed in a direction perpendicular to each other to quench the clinker. The clinker is quenched from 1300-1400°C to below 100°C within a few minutes. Traditional grate coolers are divided into three types: rotary type, vibration...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sealing device for the transmission mechanism of the grate cooler used in cement production, so as to solve the problem of the sealing of the transmission mechanism in the working process of the grate cooler proposed in the above-mentioned background technology. Disadvantages, the grate cooler requires high grate pressure, high dust concentration and high temperature

If there is a slight gap in the sealing device, high-temperature dust-containing gas will blow out, causing secondary pollution to the environment, and the leaked dust particles will affect the working efficiency of the equipment and cause damage to the equipment.
