Description

Technical Field

[0001] This utility model relates to the technical field of coal crushing and grinding devices, and more specifically, to a coal crushing and grinding device. Background Technology

[0002] Coal is a solid, combustible mineral formed gradually from ancient plants buried underground through complex biochemical and physicochemical changes. Known as "black gold" and the "food of industry," coal has been one of the primary energy sources used by humankind since the 18th century. The main component of coal is carbon, but it also contains elements such as hydrogen, sulfur, oxygen, and nitrogen. Its color is brown or black. Based on the degree of coalification, coal can be classified into peat, lignite, bituminous coal, and anthracite. According to the original materials and conditions, naturally occurring coal can be divided into three main categories: humic coal, residual humic coal, and sapropelic coal.

[0003] Based on the above, the inventors have discovered that when pulverizing and grinding coal, it is necessary to process the coal from solid blocks into powder. However, after prolonged use, this may lead to uneven coal grinding, causing blockages inside the equipment and damage to the equipment. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a coal pulverizing and grinding device, aiming to achieve a more practical purpose.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this scheme, a grinding disc is set inside the grinding box. When the grinding motor is started, the convex block and the grinding disc are rotated. The crushed coal enters the second feed inlet. The surface of the second feed inlet is inclined to facilitate the coal to enter the next step. The coal falls to the top of the convex block. Four baffles are set on the top of the convex block to prevent the coal from accumulating on the top of the convex block after it falls. This facilitates the coal to enter the gap between the grinding disc and the annular block, thereby performing the coal grinding operation. It is highly practical.

[0018] (2) In this scheme, a crushing box is set up, and the first crushing roller and the second crushing roller are rotatably connected inside the crushing box. Two meshing first gears and second gears are connected to the outside of the crushing box. The operator puts the coal into the inside of the first feed inlet, so that it enters the inside of the crushing box. The crushing motor is started, which drives the first crushing roller and the second crushing roller to crush the coal. At this time, the bottom of the first feed inlet is located above the gap between the first crushing roller and the second crushing roller, which facilitates the crushing operation of the coal.
