Description
Technical field
The invention belongs to boil sugar honey workshop section technical field in the sugaring of sugar refinery, and in particular to molasses dilute automatic control system
And method.
Background technique
Mechanism sugar refinery handles molasses using division of labor segmented mode in production at this stage.In the sugar that purging workshop section, sub-sieve come out
Then honey enters pneumatic transmission tank through piping by being pooled to opening box first, Zhu Tang workshop section is transported to by way of pneumatic transmission
Material box storage.When Zhu Tang workshop section needs to use various molasses materials, then by field worker the molasses of material box are put into dilution
In case, a certain proportion of hot water is then added, molten sand and the dilution of material are completed by mechanical stirring, when molasses are by next workshop section
After being over, worker repeat before work.Four kinds of different molasses can be generated in the daily production of factory, with a kind of sugar
Honey is calculated, and needs a set of pneumatic transmission tank, three raw material storage boxes, three dilution tanks；Each class of two people of needs management of factory at this stage
Pneumatic transmission tank, four people manage raw material storage box, and four people manage dilution tank, and daily three boats change, and need 30 workers can
Production also wants a large amount of equipment to assist.Conveying and dilution belong to different floors, lack timely and effective communication, often result in life
The error of production process link.Existing mode cost of human resources is higher, and the obtained molasses of manual operation are often not achieved
The index that production process needs, causes factories to waste, increased costs.
In existing, also there are the intelligence control system that serial dilution molasses may be implemented, such as Publication No.
The Chinese utility model patent of CN207591645U discloses a kind of sugar refinery molasses serial dilution intelligence control system, including DCS
Or PLC control system, molasses case, mixer, boiling pan and connecting pipe；Molasses case is connect by pipeline with mixer, steam
