Description

Technical Field

[0001] This application relates to the field of sugar production technology, and in particular to a suction filter device for sugar filtration. Background Technology

[0002] In current sugar production, a vacuum environment is required to speed up processing in several stages, such as vacuum filtration. In the purification stage of sugar production, vacuum pumps are often used in conjunction with suction filters for vacuum filtration. Vacuum pumps can create a rough vacuum environment, allowing the filtrate to pass smoothly through the filter medium, while impurities such as non-sugars are trapped on the surface of the filter medium, thereby purifying the sugar juice and obtaining high-purity sugar juice.

[0003] The existing vacuum pump for the filter press is equipped with a condenser. The condenser in the current structure has a flat top and the water inlet is a top-spray pedal-type water inlet. This water inlet method has problems with poor drainage and insufficient air extraction, which causes the vacuum pump to have a vacuum degree lower than that required for production. As a result, the dry filter mud after the filter press has a high light conversion and moisture content, the filter mud is thin, and there is a lot of residual sugar solution in the filter mud, resulting in sugar loss.

[0004] The information disclosed in the background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

[0037] This setting increases the vacuum level of each suction filter by 14 degrees, resulting in better slurry-liquid separation, reduced light conversion and moisture content of the resulting dry filter mud, and increased sugar recovery rate. Simultaneously, setting up multiple suction filter units effectively improves the filtration efficiency of the syrup, thereby increasing overall processing efficiency.

[0038] The device was implemented in 2024 at the Jingzhen Sugar Factory of Yunnan Xishuangbanna Yingmao Sugar Industry Co., Ltd. It effectively improved the vacuum level of the vacuum pump, reduced the light conversion and moisture content of the dry filter mud, increased sugar recovery, reduced environmental risks, and achieved the goal of cost reduction and efficiency improvement. After the modification, the vacuum level generated by the vacuum pump is 200-300 Pa, which meets the requirements for suction filtration. The moisture content of the filter mud obtained by suction filtration is reduced to below 5%, the filter mud is relatively dry, and the suction filtration effect is better.

The inlet water temperature of the condenser 21 is room temperature water. After heat exchange with the airflow, it is heated and then passed into the circulating cooling water tank 3 to cool down naturally to room temperature before re-entering the condenser 21 for heat exchange.
