Quick precipitator for clarifying during sugar making

Abstract

The invention provides a quick precipitator for clarifying during sugar making. The quick precipitator is characterized by comprising a cylinder body and a sugarcane juice flow guiding device, wherein a cavity is formed in the cylinder body and the cylinder body is composed of a cylinder and a taper hopper; an overflow trough is formed in the cavity at the upper end of the cylinder body, and is connected with a clear juice outlet; the lower end of the cylinder body is connected with a mud juice outlet pipe; the sugarcane juice flow guiding device takes the shape of an inverted funnel, and comprises a slowdown distributor, a gas disperse pipe, a gas disperse outlet pipe and a sugarcane juice inlet pipe; the slowdown distributor is fixedly connected with the gas disperse pipe; an opening is designed at the connecting part of the upper end of the slowdown distributor and the gas disperse pipe; the lower part of the slowdown distributor is fixedly connected with the inner wall of the cylinder body; the upper end of the gas disperse pipe is connected with the sugarcane juice inlet pipe and the gas disperse outlet pipe respectively; the sugarcane juice flow guiding device is positioned in the cavity of the cylinder body. The quick precipitator has an obvious clarifying effect, is good in flocculation effect, quick in settling, clear in discharged juice, few in floating sludge, high in efficiency and low in cost, and has a wide market prospect in the application of clarifying and solid-liquid separation of sugar juice in the sugar making field.

Description

technical field [0001] The invention relates to a solid-liquid separation device used for clarification of cane juice after sugarcane pressing in the field of sugar production, in particular to a fast settler for clarification of sugar production. Background technique [0002] The current process of sugar production in sugar factories is to choose sugarcane or sugar beet as raw material. Here, sugarcane is used as an example. Before extracting juice, the sugarcane is crushed and pretreated, which destroys the cell membrane of sugarcane and increases the density of cane material. After three Pressing with a roller press followed by heating, addition of clarifier and separation of the precipitate. Since the pH value, heating time and clarification time of cane juice are crucial to the quality of sugar production, it is particularly important as a clarification settler for cane juice separation and sedimentation in the process. [0003] There are many kinds of solid-liquid sep...

Problems solved by technology

[0003] There are many kinds of solid-liquid separation equipment for sugarcane juice clarification on the market. The advection type filter juice rapid sedimentation device disclosed in the Chinese patent ZL1242950.3 adopts the advection working mode and does not interfere with the free sedimentation of particles, but the disadvantages are When the flow fluctuates, the flow velocity fluctuates accordingly, forming eddy currents during the flow process, which is easy to affect the sedimentation effect; a kind of liquid level adjustable sugar juice single-layer sedimentation system publicly reported in Chinese patent ZL200920164721.0, consists of a settler, diffuser Box and flocculation reactor, among them, the settler is composed of a circular cylinder and a solid collection cone bucket, and an annular baffle group is arranged in the settler cylinder, and a multi-layer clear juice outlet pipe is arranged on the upper part of the settler, which consists of more than two layers The clear juice outlet tube is composed of each layer of juice outlet tubes at different levels

Compared with the advection fast settler, this equipment has a more balanced effect and an adjustable liquid level. The disadvantage is that it uses too many equipment and occupies a large area. With the addition of multiple blocking plates, it does not Separation of flocculation area and clear juice area, easy to mix when the flow rate of filtered juice is not smooth, and the clarification effect is not obvious
