Description

TECHNICAL FIELD

[0001] The utility model relates to cement production technical field especially relates to a cement automatic batching device of cement production line. BACKGROUND

[0002] The cement production line is a series of equipment for producing cement, mainly composed of crushing and pre-homogenization, raw material preparation homogenization, preheating decomposition, cement clinker sintering, cement grinding and packaging, etc. In the process of cement production line, at least 3 tons of material (including various raw materials, fuel, clinker, mixture, gypsum) are ground for producing 1 ton of Portland cement. According to statistics, the power consumption of dry cement production line grinding operation accounts for more than 60% of the total power consumption, of which raw material grinding accounts for more than 30%, coal grinding accounts for about 3%, and cement grinding accounts for about 40%. Therefore, it is of great significance to select reasonable grinding equipment and process flow, optimize process parameters, and correctly operate and control operation system to ensure product quality and reduce energy consumption. Portland cement production process is representative in cement production equipment, which uses limestone and clay as main raw materials, crushes, batches, grinds into raw materials, then feeds into the cement kiln for calcination into clinker, and grinds into cement with appropriate amount of gypsum (sometimes mixed with mixed materials or admixtures).

[0003] In building construction and decoration engineering, cement mortar is an essential material. However, traditional cement batching operation of cement production line often relies on manual operation. The operator adds cement batching and cement raw materials according to experience and simple measuring tools (such as bucket, scale, etc.). This manual operation method inevitably introduces large errors and makes it difficult to accurately control the proportion of various raw materials, resulting in unstable quality of cement products. In addition, there is a large gap between the stirring paddle of the traditional cement batching device of cement production line and the inner wall of the stirring container, which causes the material to accumulate on the inner wall of the container. These accumulated materials are difficult to be fully stirred, which not only affects the uniformity of stirring, but also causes difficulty in cleaning the equipment, material waste and quality risks over time. Therefore, we propose a cement automatic batching device for cement production line. UTILITY MODEL CONTENT
