Device for fast sedimentation of filtered juice of sugar refinery and control method of device

Abstract

The invention relates to a device for fast sedimentation of filtered juice of a sugar refinery and a control method of the device. The device comprises a buffer tank, a degassing tank, a mixing tank and a fast filtered juice sedimentation vessel, the buffer tank is connected with the degassing tank through a flowmeter and a regulating valve, a stop valve is arranged between an outlet of the buffer tank and an inlet of the degassing tank, and the top of the buffer tank is provided with an overflow pipe connected with the degassing tank; the degassing tank is connected with the mixing tank prior to being connected with the fast filtered juice sedimentation vessel. According to the control method, by arrangement of the electromagnetic flowmeter, the electric regulating valve, a liquid level display instrument, the overflow pipe and the like, the opening of a filtered juice valve can be controlled and regulated automatically online according to the liquid level, so that the amount of the filtered juice entering the fast sedimentation vessel in the sugar making process is relatively stable and smooth and auxiliary materials are added stably so as to realize stable settlement separation; therefore, quality of products is improved, and cost is lowered.

Description

technical field [0001] The invention relates to the technical field of the sugar industry, in particular to a device for rapid sedimentation of filtered juice in a sugar factory and a control method thereof. technical background [0002] my country's sugar cane sugar has a history of many years. According to different sugar making processes, cane white sugar can be divided into two types: sulfurized sugar and carbonized sugar. At present, most domestic sugar factories produce sulfurized sugar because of its better quality and longer shelf life. In the actual process of sugar production, it is very important to improve the recovery rate of sugar and reduce the loss of waste honey while obtaining clear juice with higher quality. At this time, some clarification methods need to be adopted. [0003] Using sugarcane as raw material, the process of making white granulated sugar, rough sugar and other products through multiple processes such as juice extraction, cleaning, evapora...

Problems solved by technology

[0025] The fast settler can settle and separate good-quality clear juice in normal operation. Its operating conditions require to be operated under "static" conditions, so the materials entering and leaving the fast settler must be very stable and balanced. In fact, there will always be equipment, materials or Human factors lead to instability and imbalance, unable to achieve the ideal "static"

In a factory with poor management conditions, if the equipment is turned on and off or the material pump is evacuated from time to time, the operation of the fast settler will be very poor, which will have a great impact on product quality.

According to the analysis, the main reasons affecting the normal operation of the fast settler and unable to achieve a balanced "static" operation are: first, the amount of filtered juice is unstable; second, the heating temperature of the filtered juice is unstable; third, the addition of auxiliary materials is unstable
