Automatic solid-liquid separation pre-limer for external pre-liming juice

Abstract

The invention discloses an automatic solid-liquid separation pre-limer for external pre-liming juice. The automatic solid-liquid separation pre-limer comprises a pre-limer body, a mixer, a cane juice inlet, a lime milk inlet and a discharge hole, wherein the mixer is arranged on the pre-limer body, a pre-liming juice solid-liquid separation device is arranged below the pre-limer body and comprises a filter screen frame and a separating medium tank covered by the filter screen frame, the separating medium can rotate around a support shaft freely, and the filter screen frame can block pre-liming juice floccules outside the filter screen frame, so that the pre-liming juice can fall into the separating medium tank through grids. The automatic solid-liquid separation pre-limer for external pre-liming juice provided by the invention has the characteristics of being low in energy consumption, simple in structure and convenient to operate.

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
