Closed cement production system

Abstract

The invention discloses a closed cement production system. The closed cement production system successively consists of a material blending station, a cyclone preheating device, a dryer, a first conveyer, a feeding device, a crusher, a pulverizer, a powder concentrator, a second conveyer and a cement bunker; the material blending station, the cyclone preheating device, the dryer, the first conveyer, the feeding device, the crusher, the pulverizer and the powder concentrator are arranged in a first pit below the ground; the cement bunker is arranged on the ground; and the feeding end of the second conveyer is positioned in the first pit while the discharging end is higher than the top surface of the cement bunker. Main equipment is transferred under the ground, the occupation area is reduced, and high-altitude buildings and operation of the ground are eliminated; and on the one hand, initial materials are horizontally or downwards conveyed, a material conveying distance is shortened, the running speed is increased, and the number of workers is reduced, on the other hand, the whole system is arranged compactly, dust collection is facilitated, low-frequency vibration can further be eliminated, noise pollution is reduced, and pollution sources such as dust and noises are controlled effectively in a centralized manner.

Description

technical field [0001] The invention belongs to the technical field of cement production lines, and in particular relates to a closed cement production system. Background technique [0002] The cement production line is a cement equipment production line composed of a series of equipment for producing cement. It is mainly composed of crushing and pre-homogenization, raw meal preparation and homogenization, preheating decomposition, cement clinker firing, cement grinding and packaging and other processes. The noise and dust pollution of the cement production line has always been a hot issue in the development of this technology. It is difficult to isolate the dust, noise and vibration. However, the existing solutions have limited effects on improving the noise and dust pollution. Local improvement measures are not taken into account in the overall plan of the production line; in addition, the cement production line occupies a large area, the cost of land use is high, there a...

Problems solved by technology

The noise and dust pollution of the cement production line has always been a hot issue in the development of this technology. It is difficult to isolate the dust, noise and vibration. However, the existing solutions have limited effects on improving the noise and dust pollution. Local improvement measures are not considered in the overall plan of the production line; in addition, the cement production line occupies a large area, the cost of land use is high, the ground buildings are many and high, the signs of industrial pollution are obvious, and the urban and rural construction planning surrounding The environment is uncoordinated, the site selection range is small, it is difficult to achieve nearby material supply, and it also increases energy consumption and cost, which is not conducive to energy saving and emission reduction and enterprise energy consumption; it is also necessary to consider the earthquake resistance and wind speed brought about by the main equipment being too high , subsidence and other irresistible problems, which lead to the limited shape and volume of each device, which greatly restricts the production capacity and regionality of the cement production line
