Detailed Description

The technical scheme of the utility model is further explained by combining the attached drawings.

The utility model relates to an improved crusher, which is characterized in that through the arrangement of a cooling cavity 8, when the crusher runs, cooling liquid can be introduced into the cooling cavity 8 to cool the inner cavity of a crushing box 2, and then the cooling of a knife roll 4 and a fixed knife 6 in the crushing box 2 is realized through the cooling of the inner cavity of the crushing box 2, so that the heat abrasion of the knife roll 4 and the fixed knife 6 is avoided; meanwhile, due to the obstruction of the cooling liquid, the noise generated in the running process of the crusher can be reduced, and the physical and psychological health of operators is protected.

Referring to fig. 1-3, a crusher with a cooling function is shown, which includes a frame 1, a crushing box 2 disposed on the frame 1, a hopper 3 communicated with the crushing box 2, a knife roll 4 rotatably disposed in the crushing box 2 around its own axial line direction, a driving assembly 5 for driving the knife roll 4 to rotate, a fixed knife 6 disposed on the crushing box 2, two cooling portions 7 respectively connected to two axial side portions of the crushing box 2 perpendicular to the knife roll 4, and a cooling cavity 8 opened in the cooling portion 7 for accommodating a cooling liquid, wherein an extending direction of the cooling cavity 8 is parallel to a length direction of the knife roll 4. In this example, the drive assembly 5 is a motor and the cooling liquid is water.

So, through letting in the cooling water in cooling chamber 8, utilize the cooling water to cool off the 2 inner chambers of broken case from 2 both sides of broken case, and then the 2 inner chambers of refrigerated broken case can realize the cooling to rotor 4 and stationary knife 6. And the cooling cavity 8 parallel to the length direction of the knife roller 4 can ensure the thoroughness of cooling the knife roller 4.

In the present embodiment, as shown in fig. 2, four stationary blades 6 are provided and are arranged in a two-by-two symmetrical manner with respect to the axial line of the knife roll 4. Two of the four fixed knives 6 are correspondingly attached to the two cooling parts 7 respectively. Thus, the two stationary blades 6 attached to the cooling unit 7 can be cooled more effectively, and the service life of the stationary blades 6 can be prolonged.

The crushing box 2 comprises two side plates 2a which are respectively positioned on two radial sides of the knife roll 4, two end plates 2b which are respectively positioned on two axial ends of the knife roll 4 and are respectively connected to two axial side portions of the two side plates 2a parallel to the knife roll 4, and two extending portions 2c which are respectively formed on two axial side portions of the end plate 2b perpendicular to the knife roll 4, wherein two cooling portions 7 are respectively connected to the two side plates 2a, and two axial ends of the parallel knife roll 4 are respectively connected with the two extending portions 2 c. In this example, the lower part of the crushing box 2 is erected on the frame 1, and the upper part thereof communicates with the hopper 3, and the side plate 2a and the end plate 2b are respectively enclosed on the horizontal circumferential side of the knife roll 4.
