The invention discloses a belt type coal pulverizer with the hot drying function. The belt type coal pulverizer comprises a pulverizer body, a conveying belt is horizontally laid on the center of thepulverizer body, a feeding opening is formed in one end of the conveying belt, the other end of the conveying belt is provided with a discharging opening, a wind shield is arranged on the dischargingopening, the upper end of the machine body is sequentially provided with a drying chamber and a coal pulverizing chamber from left to right, multiple air heaters are arranged at the upper end inside the drying chamber, and are arranged above the conveying belt, adjacent air heaters are arranged in an oppositely-spaced manner, multiple air cylinders are evenly arranged at the top end of the interior of the coal pulverizing chamber, and are correspondingly arranged above the conveying belt, pneumatic rods are vertically guided out of the lower ends of the air cylinders, one ends of the pneumaticrods are connected to the output ends of the air cylinders, and the other ends of the pneumatic rods are vertically connected with a grinding plate. Through the above manner, humid coal can be driedin advance through the air heaters, and the subsequent grinding program can be facilitated.
Description
technical field [0001] The invention relates to the field of coal pulverizers, in particular to a belt-type coal pulverizer with a thermal drying function. Background technique [0002] Coal mill is a machine for crushing and grinding coal into pulverized coal, and it is an important auxiliary equipment for pulverized coal furnace. There are vertical mills, high-pressure suspension mills, medium-speed micropowder mills, super-pressure trapezoidal mills, Raymond mills and other models. The coal grinding process is the process in which coal is broken up and its surface area is continuously increased. To increase the new surface area, the bonding forces between solid molecules must be overcome, thus consuming energy. Coal is ground into pulverized coal in a coal mill, mainly by crushing, crushing and pulverizing. The traditional coal pulverizer does not have the function of thermal drying, so it is easy to stick to the coal pulverizer when the wet coal is ground, making it i...
