Auto controlling system of sugar cane press

Abstract

The invention discloses a sugarcane-press automatic control system, including automatic regulation of sugarcane feeding, pressing, and analogue quantities of water-permeating system, artificially setting the speed of the first-stage presser, regulating the speed of the last-stage sugarcane feed belt to keep the stability of the material level of the first-stage elevated bunker, regulating the speeds of the other sugarcane feed belts at different stages to synchronize with the last-stage sugarcane feed belt, regulating the speeds of the other pressers at different stages to keep the stability of the same-stage elevated bunkers, regulating the aperture of the feed baffles of the first- and last- stage elevated bunkers to protect the pressers and avoid the overlarge torsions; according to sugarcane amount, regulating the flow of clear water, and keeping the level and temperature of the clear water box; regulating the addition of permeating water at different stages to keep the balance. It can enhance the uniformity, stability and safety of sugarcane feeding, pressing and permeating, ensure high-efficiency crushing of sugarcane.

Description

technical field [0001] The invention relates to a sugarcane pressing control system, in particular to an analog quantity control system in sugarcane pressing production. Background technique [0002] There are two main methods of extracting sugarcane juice in sugar factories, one is the squeezing method and the other is the infiltration method. The pressing method is to extract sugarcane juice from sugarcane by external force, and then produce white sugar through subsequent cleaning, evaporation, and sugar cooking sections. The production line mainly includes systems such as cane conveying, pressing, and infiltration water. [0003] Figure 1A and Figure 1B It is a process layout diagram of a common sugarcane crushing production line, such as Figure 1A As shown, the sugarcane conveying system includes east and west 1# cane conveying belts, 2# cane conveying belts, and 3# cane conveying belts. The east and west 1# conveyor belts each have a sugarcane knife machine, and the...

AI Technical Summary

Problems solved by technology

[0007] This control method is an isolated manual adjustment method, which cannot realize automatic adjustment, nor can it realize the cooperation between related physical quantities, such as the cooperation between each cane conveyor belt and each squeezer, the feeding amount of the cane conveyor belt and the squeezer. Therefore, it is difficult to evenly feed cane and squeeze evenly

Due to the amount of clean water and infiltrated water added, the water temperature cannot be controlled, and the ratio between the infiltrated water and the amount of cane cane cane cannot be filled and evenly infiltrated, which affects the extraction rate and product quality.

In addition, due to the lack of necessary interlock protection, such as fault interlock, overcurrent interlock, blocking material interlock, etc., the production safety and stability are poor
