Abstract

The invention discloses a raw material homogenization silo continuous circulation blanking control device and method. A mixing chamber is arranged at the bottom of a raw material homogenization silo. A plurality of blanking small areas are arranged between the silo wall and the mixing chamber. Each blanking small area comprises a blanking groove which is formed in the bottom of a silo body and is downwards tilted towards the bottom of the mixing chamber. A blanking opening of each blanking groove leads to the mixing chamber. The blanking control device comprises a computer, a DCS, a PLC, a plurality of first electromagnetic valves and valve opening instruments arranged on all the first electromagnetic valves. Every three first electromagnetic valves are arranged in one blanking small area, one of the three electromagnetic valves is arranged on the blanking groove of the blanking small area, and the other two electromagnetic valves are arranged on air inflation pipes on the left side and the right side of the blanking groove correspondingly. All the first electromagnetic valves and all the valve opening instruments are connected with the PLC. The PLC is connected with the DCS. The DCS is connected with the computer. According to the raw material homogenization silo continuous circulation blanking control device and method, the raw material homogenization effect can be greatly improved, and the kiln raw material quality and the clinker output can be stabilized.

Description

technical field [0001] The invention belongs to the field of cement raw material homogenization storage, in particular to a raw material homogenization storage continuous cycle feeding control device and method. Background technique [0002] The cement industry controls the uniform quality of raw materials in the production process to ensure the stability of the thermal temperature of the clinker during calcination and the quality of the clinker finished product. In order to ensure the uniformity of raw materials, measures can be taken in the four links of raw meal preparation. These four links are: 1. When mining raw materials in mines, use them according to the quality; 2. The uniformity of raw materials in the yard or storage 3. Homogenization of raw meal during the grinding process; 4. Homogenization of raw meal into raw meal storage after grinding. Among them, the task of the raw material homogenization storehouse is to eliminate the short-period powder-forming fluctua...
