Problems solved by technology

[0004] However, during the current rolling process of the coal by the roller, the coal is still piled up at the bottom under the influence of gravity, and the lifting height of the coal turning process is limited, and the turning range is small, especially when the humidity is high, the coal sticks together , the lower lifting height of coal will affect the drying effect, and the larger turning range can improve the drying effect of coal, but it will easily lead to coal fragmentation

Embodiment 1

[0046] see Figure 1-4 , a raised type coal particle environmental protection drying equipment, including a drying cylinder 1, a hot air pipe 2 is installed on the side wall of the drying cylinder 1, a cover body 3 is installed on the upper end of the drying cylinder 1, a power supply box 4 is installed on the upper end of the cover body 3, and the power supply The lower end of the box 4 is electrically connected to an electric push rod 5, and the lower end of the electric push rod 5 is fixedly connected to a lifting plate 6, and the inner bottom of the drying cylinder 1 is fixedly connected to a plurality of evenly distributed drying plates 8, on which coal is laid. For particles, a linkage rod 7 is fixedly connected between the drying plate 8 and the lifting plate 6. The drying plate 8 includes a shaped plate body 81, a raised film 82 and a plurality of stretched films 83, and the raised film 82 is fixedly connected with the linkage rod 7. There is a main hole in the center ...

Abstract

The invention discloses a raised type coal particle environmental protection drying equipment, which belongs to the technical field of coal drying. The invention can spread the coal particles on the drying plate, and use the traction effect of the linkage rod on the raised film to make it raised upward to The coal particles are turned gently, and the raised film can effectively absorb the heat outside the coal, and then use the fluidity of the heat-conducting fluid after restoring its shape to push the stretched film distributed around its annular array to be squeezed and expanded, and its adaptation After the coal particles are turned, elastic deformation occurs along the gaps between the coal particles for sufficient contact and bonding, and the absorbed heat is evenly and fully released to the coal particles. Compared with the existing drum drying method, the present invention can Under the premise of ensuring a high yield rate, the coal particles are quickly and efficiently dried.

Description

technical field [0001] The invention relates to the technical field of coal drying, and more specifically relates to a raised coal particle environmental protection drying equipment. Background technique [0002] The coal drying process refers to a special technical measure for coking coal preparation that pre-dries the furnace coal to reduce the moisture content to less than 6% and then loads it into the furnace. It has the functions of stabilizing the operation of the coke oven, improving the mechanical strength of the binder and reducing the heat consumption of coking. [0003] The current drying method is mainly the way of heating and drying. Through the transfer of heat, the hot air is urged to take away the evaporated moisture in the coal. Instead, the drying carrier used is usually a drum. During the rotation of the drum, through The inner wall of the drum transfers heat to the coal, and at the same time, the rolling drum can turn the coal, so that the coal can be co...
