Problems solved by technology

[0006] 1. The coal pulverizer in the prior art uses rapid rotation and impact to crush the coal. However, the energy consumed by this method is greatly increased, which cannot meet the needs of the existing technology.
[0007] 2. The feeding of the coal mill in the prior art is generally manually operated, which causes a lot of waste of manpower and material resources during its use, thus failing to meet the needs of the prior art

Abstract

The invention discloses an automatic feeding type coal mill for a thermal power plant, which includes a connecting port inlaid in the center of the upper surface of the body, and a feeding port inlaid in the center of the lower surface of the main body, and is characterized in that: Two first hydraulic pumps are installed on both sides of the inner wall of the main body through bolts, and the output ends of the first hydraulic pumps are threaded with the first hydraulic rods, and the ends of the two first hydraulic rods on both sides are passed through The pin shaft is rotatably connected with splints, the adjacent surfaces of the splints are welded with copper splints, the adjacent surfaces of the copper splints are welded with steel splints, and the adjacent surfaces of the steel splints are evenly welded with convex By setting the second hydraulic rod and the third hydraulic rod, coordinating with four first hydraulic rods and multiple groups of arc-shaped impact plates, it can make multiple impacts during use, so that the coal blocks clamped between the splints More effective damage.

Description

technical field [0001] The invention relates to the technical field of coal grinding equipment in power plants, in particular to an automatic feeding type coal grinding machine for thermal power plants. Background technique [0002] A coal mill is a machine that breaks coal and grinds it into coal powder. It is an important auxiliary equipment for pulverized coal furnaces. There are vertical mills, high-pressure suspension roller mills, medium-speed micro-powder mills, overpressure trapezoidal mills, and Raymond mills. [0003] The coal grinding process is the process in which coal is broken and its surface area is continuously increased. To add new surface area, the bonding forces between solid molecules must be overcome, thus expending energy. Coal is ground into pulverized coal in a coal mill, mainly through crushing, crushing and grinding. Among them, the crushing process consumes the least energy. The grinding process is the most energy-intensive. All kinds of coal...
