Calcining apparatus used for detecting and controlling temperature

Abstract

The invention discloses a calcining apparatus used for detecting and controlling temperature, which belongs to the technical field of machinery apparatus design. The calcining apparatus comprises a flue gas thermometric indicator, a preheating zone thermometric indicator, a cooling zone thermometric indicator, a discharging thermometric indicator, an ash discharging bucket, a kiln chamber, a kiln cover, and a smoke tube. the ash discharging bucket is fixed at the bottom of the kiln chamber, the kiln cover is fixed at the top of the kiln chamber, the smoke tube is arranged at the side surface of the kiln cover, the kiln chamber is divided into a preheating zone, a calcining zone and a cooling zone, which are respectively positioned at an upper part, a middle part and a lower part of the kiln chamber, and the preheating zone thermometric indicator and the cooling zone thermometric indicator are respectively arranged on the preheating zone and the cooling zone of the kiln chamber. The calcining apparatus is characterized in that the preheating at a furnace charge is uniform, the calcining status is continuous and stable, cooling of the furnace charge is uniform, labor intensity is low, work environment is good, unloading temperature is timely and accurately controlled, all the thermometric indicators are introduced into PIC through a temperature inspection point instrument, the kiln status change regulation is analyzed, and adjustment is timely carried out.

Description

technical field [0001] The invention relates to the technical field of mechanical device design, in particular to a calcining device for detecting and controlling temperature. Background technique [0002] The traditional ordinary lime shaft kiln judges the calcination temperature of the kiln based on human experience. Insufficient experience or misjudgment will cause significant quality loss. The amount of coal blending and the calcination status of the kiln generally have to wait for the lime to come out of the kiln. Accurately know before making adjustments. At this time, the quality of lime in a kiln is a foregone conclusion. It is very important to accurately judge the amount of coal blending and the calcination status of the kiln in advance. The detection of flue gas temperature is During the lime calcination process, it is very important to accurately control the temperature of the kiln surface. If the temperature of the kiln surface is not enough, the degree of lime ...
