Description

Improved bagasse pith remover

Technical Field

The utility model relates to a sugarcane processing technology field, concretely relates to modified bagasse depithing machine.

Background

One of the keys of bagasse papermaking is pulp removal, the types of equipment and processes for pulp removal are many, and multi-roller bagasse pulp removal machines are widely used in China. The bagasse pith remover of the prior patent CN200520064379 of the applicant is in a horizontal four-parallel-shaft and double-motor driving mode, and the bagasse is stirred and sieved in the machine through a four-stage rotating shaft to achieve the purpose of pith removal. The machine has reasonable structure, stable operation and high marrow removing rate. However, there are the following problems: (1) when the machine is stopped, the feeding (feeding of bagasse to a feeding port) needs to be stopped firstly, after all the bagasse in the machine is discharged within 2-3 minutes, the conveying belt and each device can be gradually stopped one by one, and particularly the machine can be stopped only when the pith remover is confirmed to have no raw material to come out, so that the trouble of starting the machine next time is reduced; (2) before starting the machine, a cover is opened to check whether a packing belt or a rope is wound on an inner roller of the machine, whether discharged bagasse or other foreign matters are filled in the roller, whether residual bagasse exists in a sieve plate groove or not, whether a roller shaft rotates lightly or not, if bagasse is filled in the machine, each roller needs to be rotated by hands, if the roller cannot rotate, less bagasse needs to be discharged, an upper cover is covered, a motor is tried to be started, whether the motor can be started or not is judged, otherwise, less bagasse is discharged, the motor can be started to operate, the motor can be prevented from being burnt out due to too large starting resistance, and the feeding operation can be carried out when each device operates normally; (3) in the pith removing operation, if the roller shaft is clamped by a packing belt and bagasse and can not rotate, the machine can be stopped only by manually judging whether the machine is stopped or the roller shaft is blocked or stopped or a motor is burnt out. The above results in complex procedures of the depithing operation, manual operation of frequently uncovering the cover by manpower or fault removal, high fault rate and low deslagging efficiency.
