Flame detection device with good protection performance for hot blast stove

Abstract

The invention relates to the technical field of hot blast stoves, and discloses a hot blast stove flame detection device with good protection performance, the hot blast stove flame detection device comprises a stove body, the right side of the stove body is fixedly connected with a mounting shell, the right side of the mounting shell is fixedly connected with a transmission shell, and the mounting shell is internally provided with a sliding device with one end extending to the upper part of the mounting shell. The bottom of the sliding device is fixedly connected with a gear shell located in the mounting shell, and an extending device is arranged in the gear shell. The flame detection device with the good protection performance for the hot-blast stove has the advantages of being good in protection effect and the like, and the problems that most existing hot-blast stoves are internally provided with flame detectors for detecting flames in the stoves, the protection effect is poor, the flame detectors are burnt by the flames in the stoves for a long time, internal circuits can be heated, an insulating layer is melted, and the flame detection efficiency is poor are solved. And meanwhile, smoke dust in the furnace is also easy to cover the surface of a sensor of the flame detector, so that the detection numerical value is inaccurate, and the use is influenced.

Description

technical field [0001] The invention relates to the technical field of hot blast stoves, in particular to a flame detection device for hot blast stoves with good protection performance. Background technique [0002] The hot blast stove is a thermal power machine, which was widely used in our country in the late 1970s. It has become a replacement product for electric heat sources and traditional steam power heat sources in many industries. There are many varieties and complete series of hot blast stoves, which are divided into two types: hand-fired and machine-fired according to the way of coal feeding, and divided into coal, oil, and gas stoves according to the type of fuel. [0003] Most of the existing hot blast stoves have a built-in flame detector to detect the flame in the furnace, and the protection effect is poor. If the flame detector is burned by the flame in the furnace for a long time, the internal circuit may be heated and the insulation layer will melt, resultin...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a flame detection device for a hot blast stove with good protection performance, which has the advantages of good protection effect, etc., and solves the problem that most of the existing hot blast stoves have built-in flame detectors to monitor the flame in the furnace. The detection and protection effect is poor, and the flame detector is burnt by the flame in the furnace for a long time, which may cause the internal circuit to be heated and cause the insulation layer to melt, resulting in a short circuit. At the same time, the smoke in the furnace is easy to cover the sensor of the flame detector Surface, resulting in inaccurate detection values, affecting the use of the problem
