Description

Technical Field

[0001] The utility model relates to the technical field of rotary kilns, in particular to a temperature early warning device at the tail of a rotary kiln. Background Art

[0002] Rotary kilns are widely used in metallurgy, building materials and other industries. They can complete different process operations such as drying, roasting, volatilization, etc. With the different industrial processes, the types of materials, heating methods, fuels, temperatures, negative pressure control conditions, etc. in the rotary kiln vary greatly. Therefore, it is necessary to monitor and warn the temperature in the rotary kiln to increase the working effect of the rotary kiln.

[0003] The existing Chinese utility model patent with reference announcement number: CN203893647U discloses a rotary kiln temperature measuring device. The utility model includes: kiln lining, temperature measuring brick, sealing shaft, thermocouple, kiln shell, end cover, and temperature sensor; the kiln lining is located in the kiln shell, and a temperature measuring hole is provided on the kiln shell. The entire temperature measuring device is mainly located in the temperature measuring hole on the circumferential surface of the rotary kiln body; the temperature measuring brick is located in the temperature measuring hole and is in close contact with the kiln lining; the inner hole of the temperature measuring brick is conical; one end of the sealing shaft is conical and the other end is cylindrical; one conical end of the sealing shaft is located in the temperature measuring brick and matches the inner conical hole of the temperature measuring brick; one cylindrical end extends out of the temperature measuring hole, is pressed and fixed on the kiln shell through the end cover; the thermocouple passes through the middle of the sealing shaft, and its free end is in free contact with the hot air in the kiln, and the other end is connected to the temperature sensor. The taper of the inner conical hole of the temperature measuring brick is 8±1℃. The temperature measuring device of the utility model adopts a direct contact measuring method, which can better ensure product quality.

[0004] Although the existing rotary kiln temperature measuring device is convenient for measuring the temperature inside the kiln, it is not convenient for measuring the temperature at the tail of the rotary kiln, which reduces the practicality of the rotary kiln tail. The cement kiln usually forms local high temperature and liquid phase at 35 meters and above. These liquid phase substances wrap the raw material powder or hazardous waste particles and stay on the inner wall of the kiln tail for a long time, resulting in the formation of crust and ring. After the ring and crust are formed, the inner diameter of the rotary kiln tail is reduced, affecting the overall ventilation effect of the rotary kiln, and increasing the hazards of using the cement rotary kiln.
