Method for manufacturing sugarcane pressing roll

Abstract

The invention aims to provide a method for manufacturing a pressing roll of a sugarcane press. The method is characterized by comprising the following process steps: (1) by adopting vermicular graphite cast iron as a raw material, casting a shell blank of the pressing roll; (2) carrying out rough turning on the top circle and two ends of the roll shell blank; (3) carrying out rough and fine boring on an inner bore of the pressing roll shell; (4) carrying out deep drilling on axial lotus holes of the pressing roll shell; (3) installing internal threads on juice blocking rings at the drilling end and tapping end of the pressing roll shell; (6) thermally sleeving the roll shell on a pressing roll shaft; (7) carrying out fine turning on the top circle and length of the pressing roll shell and turning V-shaped insections; (8) drilling slant radial juice collecting holes in the tank bottom of the V-shaped insections of the pressing roll; (9) milling large herringbone grooves in the circumference of the tooth crest of the pressing roll shell. The method provided by the invention has the advantages that the strength of the pressing roll of the sugarcane press is well satisfied; the capability and efficiency of carrying bagasse materials in the pressing process are increased; the performances of juice yield and the like of sugarcane pressing are increased.

Description

technical field [0001] The invention relates to a manufacturing method of sugar squeezing equipment in a sugarcane sugar refining enterprise, in particular to a manufacturing method of sugarcane squeezing rollers. Background technique [0002] The press roller of the sugarcane press machine is an important part installed on the press machine. The press machine is an important mechanical equipment in the sugar factory. Farmers harvest the sugarcane from the field and transport it to the sugar factory. First, the sugarcane must be pressed to extract the juice and enter the filter Clarification, heating and concentration, sugar boiling and crystallization and separation can get the final product—white sugar. Since sugarcane is rich in fibrous substances and sugarcane juice has a certain acidity, the pressing roller must meet several conditions in the process of squeezing sugarcane: (1) The pressing roller shell must be high in hardness and wear-resistant; (2) The material m...

Problems solved by technology

[0004] Since many improvements have been made to the sugarcane press rollers, the hardness, acid resistance, wear resistance, and juice discharge rate of the sugarcane press rollers have been greatly improved compared with those in the 1970s and 1980s. The best requirements of the process cannot be met, so the design engineers and material researchers of sugar machine equipment are still conducting research to find better materials and structures to achieve the best requirements for sugarcane pressing
