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 i...

Embodiment Construction

[0032] To use an automatic control system to achieve the balance and stability of the entire pressing process, the choice of control mode, the setting of the adjustment loop, and the selection of the adjusted amount and the adjustment amount of each adjustment loop are very important. Figure 1A with Figure 1B Take the squeezing production line in as an example to describe in detail the sugarcane squeezing automatic control method and the corresponding system of the embodiment of the present invention.

[0033] In this embodiment, the speed of 1# squeezer is manually set without automatic adjustment. The set value is set according to the planned production output. Through the adaptive adjustment of other control loops to meet the purpose of balanced production.

[0034] The analog control of the sugarcane conveying system includes speed regulation loops of 1#cane conveying belt, 2#cane conveying belt, and 3#cane conveying belt. Under the condition of maintaining a certain thickne...

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 control system for sugarcane squeezing, in particular to an analog quantity control system in sugarcane squeezing production. Background technique [0002] There are two main methods for extracting sugar cane juice in sugar mills, one is the squeezing method and the other is the exudation method. The squeezing method is to squeeze the sugarcane out of the sugarcane juice through the action of external force, and then produce white sand sugar through the subsequent quieting, evaporation, and sugar cooking stages. The production line mainly includes sugarcane conveying, squeezing, and water penetration systems. [0003] Figure 1A with Figure 1B It is a common process layout drawing of sugarcane squeezing production line, such as Figure 1A As shown, the sugarcane conveying system includes East and West 1# sugarcane conveying belts, 2# sugarcane conveying belts, 3# sugarcane conveying belts, east and west 1# conveying belts each w...
