Internal-tooth drum material treatment device with adjustable pitch

Abstract

The invention provides an internal-tooth drum material treatment device with an adjustable pitch. The device comprises a treatment cavity, an impurity removal chamber, a falling impurity collection device and a nut fastening device, wherein a treatment drum is a cage drum, and comprises a center shaft and a plurality of drum bars distributed on the periphery of the center shaft; drum teeth are arranged on the drum bars in a sleeving manner through connecting parts; rings of the connecting parts are arranged on the center shaft of the treatment drum in a sleeving manner; threads are uniformly formed in the whole surface of the center shaft, rotating nut pairs can move on the center shaft in a relatively large range, the rings of the connecting parts sleeved on the center shaft can be positioned and fastened on an arbitrary position, and the axial pitch between drum teeth can be randomly adjusted to realize stepless adjustment, so that the material processing range of a processing machine can be greatly increased, the machine utilization can be improved, and the production cost can be reduced.

Description

technical field [0001] The present application relates to a material processing device, in particular to a material processing device for an inner-toothed roller with adjustable tooth pitches inside the roller. Background technique [0002] Dried fruits or nuts need to be processed and processed after the pulp and peel covering the outside of the core are removed. The traditional method of removing pulp and peel is generally manual peeling by workers or stacking. The efficiency of manual stripping is low, and the sharp stripping knife may cause injuries to workers during the stripping process; the efficiency of stacking retting has been improved, but it occupies a large area, and most of them use natural or artificial acceleration. The method is that the pulp and peel rot and fall off, and a large amount of harmful substances or harmful gases will be produced during the rot process, which will cause adverse effects on the surrounding environment, and even pollute the environ...

Problems solved by technology

However, the roller teeth on the processing roller in the prior art are all directly fixed on the surface of the processing roller, and the rollers with different processing strengths have different spacings, which cannot be adjusted. If one processing strength is needed, a new roller needs to be purchased, resulting in extreme It is a huge waste, and it also greatly increases the production cost for fresh fruit processing enterprises. Therefore, it is urgent to develop a depulping and peeling device with a processing drum with adjustable axial spacing of the drum teeth.
