Automatic aiming device of coke oven vertical flame path temperature measuring gun

Abstract

The invention belongs to the technical field of coke production and provides an automatic aiming device of a coke oven vertical flame path temperature measuring gun. A temperature measuring gun with video output is used; image recognition is carried out on temperature measuring points in the vertical flame path; the relative position of the measured temperature point and the current aiming point of the temperature measuring gun is determined; motion control data of an x axis and a y axis is calculated; an x-axis motor and a y-axis motor are driven; the motor drives the corresponding cam to rotate; under the action of rocker arm pull-up springs, the cam is in close contact with bolt bearings at one ends of the corresponding rocker arms to rotate at small angles; small-angle rotation of therocker arms is transmitted to the four rocker arms of the cradle through the combination of the fisheye bearings at the ends of the pull rods and the pull rods, so that the temperature measuring gun fixed to the cradle moves at a small angle in a high-precision mode, a measured point can be rapidly and accurately aimed, and the temperature measuring precision is guaranteed.

Description

technical field [0001] The patent invention relates to an intelligent coke oven temperature measurement system, in particular to an automatic aiming device for a coke oven vertical flue temperature measuring gun. Background technique [0002] The temperature in the coke oven flue is the basis for the operation of the coke oven. There are thousands of flue paths in a coke oven. The general operation is based on the temperature of the standard flue. The standard flue is based on the coking chamber of the coke oven. Usually the coke oven has about 140 standard fire passages. At present, most of them still rely on manual measurement of the temperature of the fire passages. The measurement process consists of uncovering the furnace cover-aiming-measurement-closing the furnace cover Actions.

AI Technical Summary

Problems solved by technology

There are also methods of automatic temperature measurement, which mainly contain three kinds. One is: the temperature measurement method using a fixed infrared measuring device. The advantage is that it can monitor the temperature in the fire tunnel in real time. , and cannot be installed on all standard fireways, mainly due to cost issues

Another method is to embed the thermocouple. The advantage of this method is that the measurement method is simple. It is difficult to insert it into the standard position that needs to be measured, and the life of the thermocouple is limited at a high temperature of about 1350 °C for a long time; The depth of the thermocouple is not enough, and the life of the thermocouple can be extended, but the actual temperature inside the standing fire cannot be directly measured. It needs to be calculated to simulate the actual combustion temperature in the standing fire. The simulated temperature is affected by other factors and is not accurate.

The third is to use a temperature measuring robot to simulate the manual temperature measurement method to measure the combustion temperature of the vertical flue. The advantage is that the investment is not high and the temperature of all standard vertical flues can be measured according to the process requirements. The disadvantage is that it cannot be quickly and accurately Aiming at the position to be measured, but a sweeping measurement method, this method leads to relatively large fluctuations in the measured temperature data, and the data reliability is poor
