Precipitator with variable precipitation area for sugaring

Abstract

The invention discloses a precipitator with the variable precipitation area for sugaring. A barrel of the precipitator is formed by assembling two or more barrel bodies which have different diametersand have large tops and small bottles, a juice inlet tube which communicates to the center of the barrel body is arranged on the outside of each barrel body, a clear juice collecting ring tube is arranged on the upper portion of each barrel body, and a clear juice valve is arranged on each clear juice ring tube. According to the principle, sugar juice added with a flocculating agent enters the barrel of the precipitator through the juice inlet tube, and enters the precipitator from the lower portion of the barrel, and clear juice is drained via the clear juice collecting ring tubes. When the precipitation area requires to be increased and liquid level requires to be increased, the valve of the clear juice collecting ring tube on the lower layer is closed, along with rising of the liquid level, the sectional area of the upper portion of the precipitator and the integral working volume are increased, and the clear juice enters the clear juice collecting ring tube at the upper end and then is drained. The working volume of the precipitator can be adjusted, and furthermore, the precipitation area of the precipitator can also be adjusted.

Description

technical field [0001] The invention relates to a solid-liquid separation device used in the field of sugar production, in particular to a settler for sugar production with a variable settling area. Background technique [0002] In sugar production, after adding auxiliary materials and heating to the set temperature, the sugar juice enters the settler for solid-liquid separation, and the obtained clear juice enters the evaporation section to concentrate to obtain syrup, and then crystallizes into white sugar, and the mud juice is sent to the filtration section. Get the filter mud and use it as fertilizer. Therefore, the quality of clear juice has an important impact on product quality and scouring recovery. Since the juice added with auxiliary materials continues to react in the settler, the hydraulic retention time of the juice in the settler is not only the time of solid-liquid separation, but also the time of chemical reaction. The design of the hydraulic retention time...

Problems solved by technology

[0007] Aiming at the problem that the existing single-layer settler for sugar production cannot adjust the settlement area and working volume at the same time, the present invention proposes a settler for sugar production with a variable settlement area, which can adapt to wide variations in crushing capacity
