High-efficiency filter-press device of squeezed sugarcane juice

Abstract

The invention discloses a high-efficiency filter-press device of squeezed sugarcane juice. An inlet pipe branch 1 is connected with an outlet pipe by a three-way cock and a centrifugal pump; a branch 2 is connected with the outlet pipe by another centrifugal pump and another three-way cock; a driving gear is arranged between gears of the two three-way cocks, and synchronously drives the two three-way cocks to rotate and switch; the two three-way cocks are vertically communicated by a middle connecting pipe; the outlet pipe is connected with a sugarcane juice buffer tank having an inverted conical bottom structure; an ultrasonic vibrator is arranged on the inclined surface of the bottom; the outlet pipe is connected with a sugarcane juice filter press; and the sugarcane juice buffer tank is connected with a three-stage juicing and backflow jetter assembly. The device skillfully realizes convenient switching operation of series and parallel connections of two centrifugal pumps through the three-way cocks, improves the sugarcane juice filter-press working efficiency, and has the characteristics of simple structure, simple operation, difficult error generation and low cost; the conical bottom and the ultrasonic vibrator can effectively prevent the blockage to facilitate to input sugarcane juice; and the three-stage juicing and backflow jetter assembly improves the sugarcane squeezing sugar yield.

Description

technical field [0001] The invention relates to a device for high-efficiency pressure filtration after squeezing sugarcane juice. 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 soli...

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
