Movable high-temperature shaft kiln receiving hopper and working method thereof

Abstract

The invention relates to a movable high-temperature shaft kiln receiving hopper and a working method thereof. The movable high-temperature shaft kiln receiving hopper comprises a receiving hopper body, a discharging pipe and a receiving hopper moving device. The receiving hopper is composed of an inner cylinder, an outer cylinder, an inner cylinder overflow pipe, an outer cylinder overflow pipe, an inner cylinder feeding chute and an outer cylinder feeding chute. The receiving hopper moving device is composed of rollers and rails. The receiving hopper can adapt to various working conditions, has the safe overflow capacity and can move integrally, the convenience of internal maintenance of a kiln body is greatly improved, and the material sealing effect of the receiving hopper is further improved.

Description

technical field [0001] The invention relates to the technical field of high-temperature shaft kilns, in particular to a movable high-temperature shaft kiln receiving hopper and a working method thereof. Background technique [0002] High-temperature shaft kiln is a kind of thermal kiln equipment, which is used for calcining various high-purity refractory raw materials. The material in the kiln moves continuously from top to bottom. The top of the high-temperature shaft kiln is usually equipped with a fixed receiving hopper, which is used to add raw pellets to the kiln, and at the same time plays a certain role in material sealing to prevent the gas from escaping from the kiln or the air from outside the kiln from being sucked in. [0003] With the continuous optimization and improvement of the high-temperature calcination process, higher and higher requirements are put forward for the feeding system of the kiln, and the receiving hopper with a simple structure in the past c...

AI Technical Summary

Problems solved by technology

[0003] With the continuous optimization and improvement of the high-temperature calcination process, higher and higher requirements are put forward for the feeding system of the kiln. The receiving hopper with a simple structure in the past can no longer meet the existing production requirements.

First of all, the materials contained in the hopper are no longer limited to unburned raw meal balls, and a small amount of under-fired materials that have passed the inspection must also be returned to the kiln for reburning by the hopper to avoid waste of resources. The hopper cannot handle multiple materials in different areas

Secondly, during the production process, the kiln top material level gauge may fail or the feeding and discharging equipment may fail. The traditional receiving hopper does not have the ability to handle material overflow safely, which will lead to production shutdown in serious cases

In addition, the top space of the high-temperature shaft kiln is limited, and the traditional fixed receiving hopper makes the internal maintenance of the kiln body very difficult

At the same time, the material sealing effect of the traditional receiving hopper can no longer meet the production requirements of high-temperature shaft kiln
