Automatic control system for centrifugal filtration of mud juice in cane sugar factory

Abstract

The invention provides an automatic control system for centrifugal filtration of mud juice in a cane sugar factory. The system comprises a sugar mud settling pond, a centrifuge I, a centrifuge II, a stirring tank, a storage tank, a washing tank and a controller. The automatic control system for centrifugal filtration of the mud juice in the cane sugar factory adopts settling centrifuges to replacevacuum suction filters without filter cloth to perform solid-liquid separation on the mud juice, a new process of fast separation is realized, the material treatment time is shortened, the productionefficiency is improved, the filtered mud sucrose loss and the filtered mud quantity are reduced, the washing quantity is reduced, energy sources are saved, further comprehensive utilization of the filtered mud is promoted, and the problems of high moisture content and difficult transportation of the filtered mud and influence on clean production of the environment are solved. The system realizessolid-liquid fast separation of the mud juice in the cane sugar factory, shortens the material treatment time, improves the production efficiency, reduces the filtered mud sucrose loss and the filtered mud quantity, reduces the washing quantity and saves the energy sources.

Description

technical field [0001] The invention relates to the technical field of filtration of cane sugar factory mud juice, in particular to an automatic control system for centrifugal filtration of cane sugar factory mud juice. Background technique [0002] Guangxi's cane sugar industry has very superior resource advantages, location advantages, quality and cost advantages and market expansion advantages. Guangxi is a key sugar-producing area in the country. It has an advantageous geographical location, abundant rainfall and sufficient sunshine. It has a unique geographical resource advantage for sugarcane planting. In recent years, Guangxi has introduced the means of internal and external connections, introduced funds and technologies, and promoted the development of the sugar industry to a higher level, higher scale, and higher level. The large-scale backbone enterprises and enterprise groups with competitive advantages have continuously improved their industrial concentration, a...

AI Technical Summary

Problems solved by technology

However, these equipments have the following disadvantages in the process of production and use: first, the water content of the discharged filter mud is relatively high, reaching more than 70%, which increases the amount of transportation and treatment discharged from the factory by the enterprise, and is not conducive to the cleaning of the environment; The sugar content of the filter mud is 6.3% (the sugar content of the wet filter mud is 1.9%), and the sugar loss is relatively large; the third is that the amount of washing water is relatively large when the vacuum suction filter is used to process the mud juice, reaching about 8%, which is not conducive to the subsequent process (evaporation) Material handling, increased evaporation, increased energy consumption

Due to the large amount of washing water and the high moisture content of the filter mud, the vacuum suction filter without filter cloth causes certain pollution to the environment, and it is difficult to transport and further comprehensive utilization is difficult, which puts a certain pressure on the environment; at the same time, due to the excessive washing water, Cause the filtrate hammer to be low, increase the evaporation of the subsequent process
