Embodiment 1

[0024] Such as figure 1 and figure 2Shown is an anti-wear device for crushing parts suitable for hot ore processing equipment. The hot ore processing equipment includes a crushing body 1, and a crushing roller shaft 2 is arranged inside the crushing body 1. Driven by a drive motor 3; the crushing roller shaft 2 is provided with a plurality of crushing end teeth 4 extending perpendicular to the axis of the crushing roller shaft 2, and a plurality of auxiliary crushing end teeth are arranged on the inner wall of the crushing body 1 5. The crushing end teeth 4 and the auxiliary crushing end teeth 5 are alternately distributed. The crushing end teeth 4 and the auxiliary crushing end teeth 5 both include a tooth core 6 and a tooth sleeve 7, which are independent of each other; the tooth sleeve 7 adopts a hollow structure and is arranged outside the tooth core 6; The side end surface of the core 6 is provided with a plurality of sets of first transmission end bodies 8, which are ...

Embodiment 2

[0031] As an improvement of the present invention, such as figure 2 As shown, among the tooth cores 6, the front end and rear end of each group of first transmission end bodies 8 respectively include limiting end bodies 10 distributed in a ring perpendicular to the axial direction of the tooth core, and the two limiting ends The distance between the bodies 10 is 1.1 times the diameter of the bottom surface of any second transmission end body 9 . Adopting the above-mentioned technical scheme, it can effectively avoid excessive displacement in the axial direction of the gear sleeve during the rotation process of the gear sleeve relative to the gear core through the setting of the limit end body, so that the gear sleeve is separated from the gear core; at the same time , the distance setting of the limit end body can provide a certain range of axial displacement for the gear sleeve, so that part of the impact received by the gear sleeve can be further dispersed through the axial...

Embodiment 3

[0034] As an improvement of the present invention, such as Figure 5 As shown, a plurality of crushing teeth 11 are arranged on the outer wall of the tooth sleeve, and each crushing tooth 11 includes a connection surface 111 and a crushing surface 112, wherein the connection surface 111 is located on the outer wall of the tooth sleeve 7, and the crushing The surface 112 extends along the radial direction of the tooth sleeve 7 , and the crushing teeth 11 extend from the connecting surface 111 in an arc shape toward the crushing surface 112 . Adopting the above-mentioned technical scheme, it can make the crushing end teeth and the auxiliary crushing end teeth in the process of crushing work, through the setting of the crushing teeth to form a rigid structural part protruding from the surface of the tooth sleeve, so that it can significantly improve the thermal stability of the ore. crushing effect; at the same time, the setting of the above-mentioned crushing teeth can make the ...

Abstract

The invention discloses a breaking part abrasion-resistance device suitable for a hot mine machining device. The breaking part abrasion-resistance device comprises breaking end teeth and auxiliary breaking end teeth, wherein the breaking end teeth and the auxiliary breaking end teeth are distributed in a staggered manner. The breaking end teeth and the auxiliary breaking end teeth comprise tooth cores and tooth sleeves. The tooth sleeves are arranged outside the tooth coress. A plurality of sets of first transmission end bodies are arranged on the side end faces of the tooth cores. A plurality of sets of second transmission end bodies are arranged on the inner walls of the tooth sleeves. Any set of first transmission end bodies correspond to one set of second transmission end bodies, wherein the first transmission end bodies and the corresponding second transmission end bodies are located in the same axial position of the corresponding tooth core. By means of the breaking part abrasion-resistance device suitable for the hot mine machining device, the impact force and the friction force which are borne by the breaking end teeth and the auxiliary breaking end teeth in the working process can be effectively controlled, and therefore in the long-term working process, the abrasion degree of the breaking end teeth and the auxiliary breaking end teeth is effectively reduced, and the abrasion-resistance performance of a whole breaking part is obviously improved.

Description

technical field [0001] The invention relates to mineral processing equipment in the metallurgical process, in particular to an anti-wear device for crushing parts suitable for hot ore processing equipment. Background technique [0002] In the process of deep processing of minerals, it is necessary to preliminarily process the mineral raw materials into the size required by the relevant process, so as to avoid damage to the relevant process equipment and improve processing efficiency. The existing preliminary mineral processing procedure is usually to crush the heated mineral raw materials, that is, to carry out hot ore crushing processing. However, due to the high hardness of mineral raw materials, the existing hot ore crushing processing equipment often has serious wear and tear on the internal crushing parts after long-term processing, which makes the overall equipment unable to continue to work, which not only makes the equipment The cost of use is greatly increased, so ...
