Vertical split left and right mill chamber structure

Abstract

The invention discloses a perpendicular subdivision left-right-type grinding chamber structure. The perpendicular subdivision left-right-type grinding chamber structure comprises a left grinding chamber, a right grinding chamber horizontally opposite to the left grinding chamber, a guide rail arranged below the left grinding chamber, a walking mechanism movably arranged on the guide rail, and a driving mechanism connected with the walking mechanism, wherein the left grinding chamber is borne on the walking mechanism. The driving mechanism drives the walking mechanism to move along the guide rail, so that the left grinding chamber and the right grinding chamber are separated or folded. The left grinding chamber and the right grinding chamber are opened in a sliding-door mode, the time for replacing grinding pieces is short, grinding piece disassembling and assembling and mechanical sealing are convenient, a cantilever of the head of a spindle is short, the good shock resistance and impact resistance are achieved, the better auxiliary supporting effect is achieved, meanwhile, time and labor are saved, operation is convenient, and the recovery precision of folding the chambers again after opening the chambers is high.

Description

technical field [0001] The invention relates to the technical field of thermal mills for manufacturing fiberboards, in particular to a vertically split left and right grinding chamber structure. Background technique [0002] During the fiber preparation process of the thermal refiner, due to the wear of the dynamic and static grinding plates, the grinding chamber needs to be opened periodically to replace the dynamic and static grinding plates. During the replacement of the dynamic and static grinding plates, the entire production line needs to stop running. [0003] Currently, there are two ways to open the grinding chamber to replace the dynamic and static grinding discs in the large thermal grinding machines. The first type is that the grinding chamber body of the heat refiner is a horizontally split up-and-down structure, and the static grinding disc of the grinding chamber body is removed by a hoist, the static grinding disc is replaced, and the dynamic grinding disc is...

Problems solved by technology

However, the disadvantage of this method is that it is necessary to manually open or close the side door, which is time-consuming and labor-intensive compared to a large heat grinder, and the operation is very inconvenient
