A device for extracting sugarcane juice and pressing it

Abstract

The invention discloses a sugarcane juicing and efficient filter pressing device which comprises an inlet pipe, an outlet pipe and two centrifugal pumps, wherein the inlet pipe is divided into two pipelines, and the two centrifugal pumps are transmitted by one motor; one of the pipes is connected with the outlet pipe through a three-way plug cock and one of the centrifugal pumps while the other pipeline is connected with the outlet pipe through the centrifugal pump and the other three-way plug cock; the two three-way plug cocks are communicated with each other up and down through a middle connecting pipe; the inlet pipe is connected with a sugarcane juice buffer tank which has a reversed cone-shaped bottom structure, and an ultrasonic vibrator is arranged on a bottom bevel; the outlet pipe is connected with a sugarcane juice filter press, and the sugarcane juice buffer tank is connected with a three-level juicing and countercurrent-spraying device. The device disclosed by the invention skillfully realizes a free switch operation of serial and parallel connections through the three-way plug cocks, so that the sugarcane juice filter pressing work efficiency is improved. The device has the characteristics of being simple in structure, simple to operate, difficult to make mistake and low in cost. The cone bottom and the ultrasonic vibrator therein can be used for effectively preventing blockage, so that input of the sugarcane is facilitated; the three-level juicing and countercurrent-spraying device effectively improves the syrup yield of sugarcane squeezing.

Description

technical field [0001] The invention relates to a device for extracting sugarcane juice and a high-efficiency filter press. Background technique [0002] In southern my country, sugarcane is mainly used as raw material for sugar production. Squeezing sugarcane and washing out sugar is a very important step in sugarcane sugar production. The pressing and washing of sugarcane is directly related to the yield of sucrose. However, the existing sugarcane juice is generally single-stage squeezed, which is difficult to achieve a higher squeezed sugar rate, and there are more sugar residues in the bagasse. Therefore, effective pressing of sugarcane combined with spray washing to increase the sugar yield has important practical value for the sugarcane sugar industry. [0003] After the pressing is completed, pressing the sugarcane juice is an indispensable step in the sugarcane sugar industry. The sugarcane juice obtained by pressing the sugarcane often contains insoluble solid impu...

Problems solved by technology

[0005] However, in the filter press operation, the existing centrifugal pumps cannot automatically adapt to such a process to achieve an ideal working state of high efficiency and high quality.

Generally, when a centrifugal pump performs filter press operation, the head of the filter press is low in the early stage, but the flow rate is large, so that the motor is in an overload state, and it is easy to burn the motor; The flow rate decreases rapidly. At this time, although the motor works in a light-load and low-power state, the filter press efficiency is very low; although the filter press pump has the maximum head output state, due to the small flow rate of the filter press fluid, the filter press cannot be fully utilized. Work performance and improve work efficiency
