Embodiment

[0021] Embodiment: a kind of crusher oil seal device, see Figure 1 to Figure 3 , including the crusher shaft 2 equipped with an oil seal, and the cover body 1 wrapped on the oil seal. The shape of the cover body 1 is in the shape of a spinning cone. for diversion.

[0022] Both ends of the cover body 1 are rotationally connected with the crusher shaft 2 through bearings, and three support rings 4 are welded on the periphery of the cover body, and are evenly distributed along the axial direction of the cover body 1. The support rings 4 are connected to the cover body 1 through a connecting plate 5, The connecting plate 5 is welded on the cover body 1, and the supporting ring 4 is welded on the connecting plate.

[0023] The support ring 4 is provided with stoppers for bearing the impact of materials. The stoppers are a plurality of strip plates 3 arranged on the support ring 4 at intervals and parallel to the shaft 2 of the crusher (the stoppers can also be round rods or oth...

Abstract

The invention discloses an oil seal device of a crusher. The technical problem that oil seal faults are caused due to the fact that an oil seal is easily damaged in the process of crushing materials by utilizing the crusher is solved. The oil seal device comprises a crusher shaft provided with the oil seal, and further comprises a cover body wrapping the oil seal, the two ends of the cover body are rotationally connected with a crusher shaft through bearings, at least one supporting ring is fixed on the periphery of the cover body, and material blocking parts used for bearing material impact are arranged on the circumferences of the supporting rings. Due to the arrangement of the cover body, the oil seal can be protected from entering a material powder body, the impact damage of large materials to the oil seal can be avoided, the occurrence of the oil seal faults is reduced, and the production efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of graphite negative electrode material production equipment, in particular to a crusher oil seal device. Background technique [0002] Oil seal is the customary title of general seals, simply put, it is the seal of lubricating oil. It is a mechanical component used to seal grease, and its function is to isolate the parts that need to be lubricated from the output parts in the transmission parts, so as not to let the lubricating oil leak. [0003] At present, lithium-ion secondary batteries mainly use graphite micropowder as the negative electrode material of the conductive negative electrode, and its particle size is usually between 3 μm and 30 μm. Graphite negative electrode materials need to be crushed during the production process. The crushing is usually carried out by a crusher. However, in the process of crushing the material with a crusher, it will cause damage to the operation of the oil seal, and ...
