A dynamic monitoring device and monitoring method for ceramic tunnel kiln lining spalling

Abstract

The invention discloses a dynamic monitoring device for ceramic tunnel kiln lining peeling. A ceramic tunnel kiln comprises a kiln body, and two rows of nozzles are symmetrically arranged on the two sides of the kiln body correspondingly. The kiln body comprises a preheating section, a sintering section and a cooling section. The dynamic monitoring device comprises a patrolling device, a temperature detector and a controller. The patrolling device comprises a patrolling robot, a drive device and a track arranged around the kiln body. The temperature detector is arranged on the patrolling robot. The patrolling robot is driven by the drive device to run on the track. The temperature detector transmits monitoring signals received around the kiln body to the controller in real time. The invention further correspondingly provides a monitoring method of the dynamic monitoring device. The dynamic monitoring device is wide in monitoring range, small in occupied operation space and high in monitoring efficiency, and the monitoring method is simple and convenient to conduct.

Description

technical field [0001] The invention belongs to the field of ceramic tunnel kilns, and in particular relates to a dynamic monitoring device and a monitoring method for dangerous situations of ceramic tunnel kilns. Background technique [0002] In the production process of refractory materials, ceramics and other products, firing is a very important process, which directly affects the output and quality of products. There are two main types of firing equipment: continuous kilns, such as tunnel kilns, and intermittent kilns, such as downdraft kilns. Tunnel kiln is a continuous flame heating kiln. It is generally a long linear tunnel with fixed walls and vaults on both sides and top. It is mainly used for firing refractory materials, ceramics, and building bricks. [0003] Tunnel kiln can be divided into three zones in terms of working principle: preheating zone, firing zone and cooling zone. The green body (unfired semi-finished product) is dried to a certain amount of water...

Problems solved by technology

[0007] 1. The monitoring range is small and the installation cost is high: in the prior art, an up and down swing head type infrared temperature measuring device is generally installed at one or more positions on the ground level of the tunnel kiln, and the surface temperature signal of the kiln body is collected during production. It can only monitor the surface temperature value of a small part of the tunnel kiln, and the monitoring range is very small, which cannot reflect the real situation, so it is easy to have monitoring dead angles, which will reduce the safety factor of the tunnel kiln and bring great harm to the personal safety of the operators. Hidden dangers

However, if an up and down head-type infrared temperature measuring device is installed at multiple points of the tunnel kiln, the installation and maintenance costs will be too high, which will seriously affect the economy of production

[0008] 2. It is impossible to predict the location of the furnace lining peeling off: due to the inability to fully scan the kiln body covering the entire tunnel kiln, it is not possible to physically model the various positions on the tunnel kiln body in the prior art, so that even when the temperature measuring device detects the temperature When the value changes, it is impossible to predict the corresponding location of furnace lining peeling, and it is also impossible to give reference repair suggestions, which leads to the operator having to find the high temperature point of furnace lining peeling one by one in the whole kiln body, which is cumbersome and increases labor. strength
