Automatic lime slaking control device

Abstract

The invention relates to an automatic lime slaking control device which comprises a lime slaking bucket, a lime conveying part, a water inlet part, a compressed air part, a lime milk discharge tube and a PLC (Programmable Logic Controller), wherein the lime conveying part is communicated with one side of the top of the lime slaking bucket; the water inlet part is communicated with the other side of the top of the lime slaking bucket; the compressed air part is communicated with the bottom of the lime slaking bucket; the lime milk discharge tube is connected with the bottom of the lime slakingbucket; the PLC is used for controlling the lime conveying part and the water inlet part to replenish corresponding amounts of lime and water into the lime slaking bucket after slaking is performed topreset time, and furthermore, the concentration of lime milk obtained from slaking at present can be adjusted, and lime milk of a preset concentration can be finally made. The device has an automaticcontrol function, low in power consumption, small in equipment abrasion and simple in structure, the labor can be saved, the lime milk obtained from slaking is high in quality and uniform and stablein concentration, the slaking time can be adjusted randomly according to lime quality and feeding amounts, a high lime slaking completion rate is achieved, and a small amount of lime components are retained in residues.

Description

technical field [0001] The invention relates to the field of sugar-making equipment, in particular to a lime elimination and automatic control device. Background technique [0002] The lime disinfection equipment currently used in the sugar factory is a horizontal drum disinfection machine. The working principle of this horizontal drum type disinfection machine is: one end enters lime, and the other end enters water. The lime and water are in countercurrent contact and chemical reaction occurs. milk of lime. [0003] The disinfection machine has the advantages of continuous operation, that is, continuous feeding of materials and water, continuous disinfection, and continuous output of lime milk. The work is simple and convenient, and requires less labor. However, this kind of equipment also has relatively large disadvantages, that is, the level of automation is poor, and due to continuous feeding and continuous water inflow, there is no good metering, and the concentration ...

AI Technical Summary

Problems solved by technology

However, this kind of equipment also has relatively large disadvantages, that is, the level of automation is poor, and due to continuous feeding and continuous water inflow, there is no good metering, and the concentration of milk of lime after digestion fluctuates relatively greatly, which has a great impact on the stability of process control. The time of decontamination cannot be adjusted in proportion to the amount of feed and the time of decontamination. The complete rate of decontamination is low, and there are more lime components in the remaining residue, which causes greater waste, consumes more power, and causes equipment wear and tear. Big
