Automatic solid-liquid separation prelimer

Abstract

The invention discloses an automatic solid-liquid separation prelimer. The automatic solid-liquid separation prelimer comprises a barrel body as well as a stirrer, a cane juice inlet and a lime milk inlet which are arranged on the barrel body, wherein the barrel body is divided into four parts, namely, a reaction chamber, a flocculation chamber, a filtering chamber and a separation liquid chamber; a channel port with a valve is formed in a partition board between every two adjacent chambers; a filtering net frame used for filtering out flocculation is arranged on the channel port between the filtering chamber and the separation liquid chamber and can freely rotate around a supporting shaft; the bottom of the filtering chamber is inclined from the middle to flocculation discharge ports in two sides of the barrel body. The automatic solid-liquid separation prelimer has the characteristics of low energy consumption, simple structure and convenience in operation.

Description

technical field [0001] The invention relates to a sugar making equipment, in particular to an automatic solid-liquid separation pre-ash bucket. Background technique [0002] The sugar making process generally includes juice extraction, cleaning, evaporation, crystallization, nectar separation, drying and other processes. The cleaning process is pre-ashing-heating-main ash-one carbonation-one filtration. Pre-ashing is an important link in the cleaning process, and the quality of pre-ashing has a great influence on subsequent processes. The pre-ash bucket is a device used to add a small amount of lime milk or reflow juice to treat mixed juice or oozing juice during the pre-ash process. [0003] During the pre-ashing process, a large number of impurity flocs are together, and most pre-ashing equipment cannot handle the flocs. The flocs follow the pre-lime juice into the main ash equipment and dissolve again, which increases the burden of the main ash process on the one hand, ...

AI Technical Summary

Problems solved by technology

However, the air flotation separation device uses multiple pumping equipment in the material transportation process, which consumes a lot of energy; the solid-liquid separation process uses air flotation technology, and the process is relatively complicated.

[0007] Therefore, it is very necessary to remove the flocs after the pre-ashing process, but the existing technology cannot conveniently realize solid-liquid separation under the premise of low energy consumption, and it is necessary to make further technical improvements
