Abstract

This utility model discloses a preheater material distribution device, relating to the field of limestone production technology. The utility model includes a preheating box, a uniform material distribution assembly, and a lifting assembly. The preheating box has a cover plate on top, and a receiving shell on top of the cover plate. The bottom of the receiving shell extends into the inner cavity of the preheating box. The uniform material distribution assembly includes a first motor, the bottom of which is fixedly connected to the preheating box.

Description

Technical Field

[0001] This utility model belongs to the field of limestone production technology, and in particular relates to a preheater material distribution device. Background Technology

[0002] Limestone production refers to the process of pre-treating natural limestone ore through mining, crushing, and screening, and then sending it to a lime kiln for high-temperature calcination to decompose it into calcium oxide and carbon dioxide. During this process, the calcium carbonate in the limestone undergoes a chemical change at high temperatures, releasing gas and transforming into solid quicklime. The quicklime produced can be used in many fields such as construction, steel, and environmental protection, and has a wide range of applications. In the process of limestone formation, a vertical kiln is used to calcine the raw materials, and preheating treatment is required before limestone is calcined.

[0003] A Chinese patent application with publication number CN218146402U discloses a limestone preheater that can uniformly and fully preheat limestone, improving the decomposition efficiency of limestone before it enters the rotary kiln for calcination, and can recover and utilize the waste heat after preheating. However, the above technology lacks a uniform material distribution function. Although stirring after crushing the limestone can improve the preheating efficiency and shorten the preheating time, it causes the limestone to stratify during the stirring process. Large limestone particles will be located at the top, while fine limestone particles will be deposited at the bottom. This results in small gaps between the limestone particles in the central part, preventing hot air from flowing and heating them, leading to a large temperature difference between the inside and outside, which is not conducive to use.
