Classified filtering pre-liming tank

Abstract

The invention discloses a classified filtering pre-liming tank. The classified filtering pre-liming tank comprises a tank body, a mixer, a cane juice inlet, a lime milk inlet and a discharging port, wherein the mixer, the can juice inlet, the lime milk inlet and the discharging port are arranged on the tank body. A pre-limed juice solid-liquid separating device is arranged under the tank body and composed of 2-4 layers of filtering mechanisms; every layer of filtering mechanism is composed of a filter mesh frame and a filtering channel; the filtering channel of the top layer is connected with the discharging port under the tank body; every filter mesh frame is vertically arranged inside the corresponding filtering channel, the filtering channel at the inner bottom of the filter mesh frame is provided with a separated liquid outlet; the separated liquid outlets of the filtering channels of the neighboring two layers are communicated; the filter mesh frames can rotate freely around a support shaft. The classified filtering pre-liming tank has the advantages 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 a graded filter 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, and affects the conce...

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
