Embodiment 1

[0033] see figure 1 , In the clinker production process, the raw coal shed transports the raw coal to the pre-homogenization shed, the pre-homogenization jet pre-homogenizes the raw coal and transfers it to the air-swept mill, and the raw coal after the air-sweep mill is stacked to the pulverized coal silo , pulverized coal provides fuel for decomposition furnace and rotary kiln;

[0034] After the limestone is mined in the limestone mine, the limestone is put into the limestone crusher for crushing. The crushed limestone is stacked in the pre-homogenization yard, and the limestone in the pre-homogenization yard is put into the computer automatic batching control system. Cooperate with the iron powder pile shed, the iron powder pile shed puts iron powder into the computer automatic batching control system;

[0035] The clay pile shed puts clay into the microcomputer automatic batching control system, and at the same time cooperates with the shale pile shed, and the shale pile...

Embodiment 2

[0044] see figure 2 , The cement production process uses the clinker in the clinker homogenization silo for clinker deployment, and the prepared clinker can be transmitted to the microcomputer automatic batching control system. connected;

[0045] The gypsum shed conveys gypsum to the microcomputer automatic batching control system. The gypsum passes through the gypsum crusher during the conveying process. The gypsum crusher crushes the gypsum. The crushed gypsum is stacked and stored in the gypsum mixing warehouse. transmission connection;

[0046] The mixed material stacking shed transports the mixed material to the mixed material mixing warehouse, and then transfers it to the microcomputer automatic batching control system after being mixed through the mixed material mixing warehouse.

[0047] In the cement production process, the microcomputer automatic batching control system batches the clinker, gypsum and mixed materials, and then transfers the raw materials to the r...

Abstract

The invention discloses a biomass-substituted cement kiln fuel calcined silicate clinker and a preparation method thereof. The preparation method comprises a clinker production process and a cement production process, the clinker produced by the clinker production process is placed in a clinker homogenization silo, the clinker production process adopts the clinker in the clinker homogenization silo to produce cement, both the clinker production process and the cement production process use a microcomputer automatic batching control system, and the microcomputer automatic batching control system acts on batching procedures in the clinker production process and the cement production process. In the clinker production process, a microcomputer automatic batching control system acts on batchinginput of a pre-homogenizing storage yard and a clay stacking shed, and in the cement production process, the microcomputer automatic batching control system acts on batching input of clinker blending, a gypsum stacking shed and a mixed material stacking shed. According to the invention, the microcomputer automatic batching control system is adopted to accurately and automatically proportion ingredients in a clinker production process and a cement production process, so that the production quality of clinker and cement can be improved.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a biomass-substituting cement kiln fuel calcined silicate clinker and a preparation method thereof. Background technique [0002] In the process of cement production, raw materials need to be proportioned to make clinker. After a series of processing, clinker is made into cement, and both clinker and cement can be packaged and sold. Building materials are very versatile. [0003] After extensive search, the prior art was found. The publication number is CN1064649C, which discloses a cement production method. The cement raw meal powder and coal powder are mixed in a certain proportion to form blocks, which are stacked in wheel kilns and tunnel kilns. Or calcined in a down-flame kiln, and the calcined material is coarsely crushed and ground with additives to obtain cement products. The invention overcomes the disadvantages of easy change of raw material ratio, insuffici...
