Problems solved by technology

[0002] In coal processing plants, there are more lumpy coals in some coal piles, which are easy to cause wear or damage to equipment during the production of briquettes, reducing the service life of equipment, and the existing coal pulverizers are often noisy when working , and generate dust
[0003] In addition, the amount of feed and the dry and wet conditions of the coal often lead to unstable working current of the motor, which is easy to cause damage to the motor

Embodiment Construction

[0017] Embodiment of the present invention is described below in conjunction with accompanying drawing, embodiment does not constitute limitation of the present invention:

[0018] Such as figure 1 , figure 2 As shown, the structure of this kind of block coal crushing device includes a crushing bin with two ends closed in the transverse direction. The crushing bin includes a bin wall 1, a tapered convex post 2 and a rotating shaft 3. A rotating shaft 3 is provided in the middle of the interior of the crushing bin. The upper surface of the rotating shaft 3 is provided with a tapered boss 2. The crushing bin is fixed on the frame 12 through a fixed support 4. The crushing bin is directly below the A motor 16 is provided, and the rotating shaft 3 is connected with the motor 16 through a belt. When in use, the rotating shaft is driven by the motor, thereby driving the rotation of the conical protrusion, and the conical protrusion crushes the coal blocks entering the crushing bi...

Abstract

The invention relates to the technical field of coal smashing and processing, in particular to a blocky coal smashing device. The smashing device achieves the secondary smashing function. Noise is lowered and the amount of pulverized coal is reduced while coal blocks are fully smashed. The device structurally comprises a transverse smashing bin with the two ends closed. The smashing bin comprises a bin wall, a conical protruding column and a rotary shaft structure. A secondary smashing device is arranged below the right side of the smashing bin. The secondary smashing device comprises a supporting base and an extruding shaft. A supporting column is arranged below the extruding shaft. A first conveying mechanism comprises a first roller, a second roller, an auxiliary roller and a conveying belt arranged on the outer surface of the first roller, the outer surface of the second roller and the outer surface of the auxiliary roller in a sleeving mode. The extruding shaft and the first conveying mechanism are connected with a motor through a belt. The blocky coal smashing device is thorough in smashing, convenient to use and applicable to various coal processing factories.

Description

technical field [0001] The invention relates to the technical field of coal crushing and processing, in particular to a block coal crushing device. Background technique [0002] In coal processing plants, there are more lumpy coals in some coal piles, which are easy to cause wear or damage to equipment during the production of briquettes, reducing the service life of equipment, and the existing coal pulverizers are often noisy when working , and generate dust. [0003] In addition, the amount of feed and the dry and wet conditions of the coal often lead to unstable working current of the motor, which is easy to cause damage to the motor. Contents of the invention [0004] The technical task of the present invention is to provide a block coal crushing device aiming at the above-mentioned deficiencies in the prior art, the crushing device realizes the function of secondary crushing, and reduces the noise and the amount of pulverized coal while fully crushing the coal block ...
