A sugarcane press roll

Abstract

The invention belongs to the field of sugarcane press roll structure in sugar factories. A sugarcane pressing roll, comprising a roll shell and a roll shaft, the roll shell is thermally sleeved on the roll shaft; the roll shell originally includes a rack, an arc plate and a support frame from the outside to the inside; the support frame passes through A plurality of annular supporting surfaces are shrunk on the roller shaft, the arc-shaped plates are installed on the supporting frame to form a cylindrical surface, and the racks are evenly arranged on the arc-shaped plates. The present invention can adopt a casting structure or a non-casting structure to change the shortcomings of the existing sugarcane press roller structure, and has the advantages of less raw materials, short manufacturing time, low processing cost, long service life, good wear resistance, and low maintenance difficulty.

Description

technical field [0001] The invention belongs to the field of sugarcane press roll structures in sugar mills, in particular to a sugarcane press roll. Background technique [0002] The sugarcane press is a mechanical equipment used by sugar companies to extract sugarcane juice and realize solid-liquid separation. There are multiple rolls on the sugarcane press. The rolls include a forged steel mandrel (roller shaft) and a cast cylindrical roll shell. The outer surface of the roll shell is evenly distributed along the circumference with several V-shaped teeth. The V-shaped teeth of adjacent rolls are The teeth correspond to the meshing. [0003] In order to improve the speed of sugarcane extraction and extraction, an axial juice discharge hole is usually set on the roller shell, similar to the lotus root tube hole. [0004] The basic process of the pressure roll on the sugarcane press is: casting roll shell - machining of the inner hole of the roll shell, etc. - roll shell h...

AI Technical Summary

Problems solved by technology

[0005] It is not difficult to see that most of the problems of the rollers are concentrated on the roller shell. The roller shell process is first cast and then machined; from production to work operation, there are: many manufacturing raw materials, long manufacturing time, high processing cost, and short service life. , not wear-resistant, easy to break teeth, difficult maintenance and high maintenance cost and other prominent problems
