Material temperature detection and control device for sintering pellet annular cooler

Abstract

The invention relates to a temperature detection and control device, in particular to a material temperature detection and control device for a sintering pellet annular cooler. The material temperature detection and control device comprises the annular cooler and an annular cooler discharge hopper communicated with the tail of the annular cooler, and is characterized by further comprising more than one infrared thermometer arranged above an annular cooler discharge opening by a heat insulation bracket, wherein the infrared thermometers are connected with a control device, and spray pipes are arranged above the tail of the annular cooler and above the annular cooler discharge hopper respectively. The material temperature detection and control device has the benefits that in a sintering pellet cooling process, a cooled material temperature field at the tail of the annular cooler is indirectly monitored by the infrared thermometers, and after a temperature is within a set range, corresponding movement protection is conducted by contrast judgment of a temperature control device. In addition, a discharge temperature of the annular cooler can be effectively controlled within a safe range, so that damage or ignition of an adhesive tape machine due to the excess temperature is avoided, and equipment damage, economic losses and casualties due to the excess temperature are avoided.

Description

technical field [0001] The invention belongs to the technical field of measurement and control for the metallurgical industry, and specifically relates to a temperature detection and control device, in particular to a material temperature detection and control device for a sintering pellet ring cooler. Background technique [0002] In the existing domestic sintering and pelletizing process, the hot ore is cooled to a certain level by the ring cooler, and then transferred by the belt conveyor. Due to complex reasons such as poor control of the roasting link, unreasonable cooling time and air volume, and load production, etc., the ring cooling is often caused. In the end, the temperature of the material is too high, and even the red ore falls, causing the tape to catch fire, causing a fire, burning the equipment, and even causing a major safety accident with casualties, seriously affecting normal production, causing unnecessary economic losses and casualties, and extremely harm...

Problems solved by technology

[0002] In the existing domestic sintering and pelletizing process, the hot ore is cooled to a certain level by the ring cooler, and then transferred by the belt conveyor. Due to complex reasons such as poor control of the roasting link, unreasonable cooling time and air volume, and load production, etc., the ring cooling is often caused. In the end, the temperature of the material is too high, and even the red ore falls, causing the tape to catch fire, causing a fire, burning the equipment, and even causing a major safety accident with casualties, seriously affecting normal production, causing unnecessary economic losses and casualties, and extremely harmful.

If the cooling speed is too fast, it will cause the product quality to decline, and the waste gas of sintering pellets will not be fully utilized and other negative effects.
