A special vacuum drum filter for treating ultrafiltration tank bottoms and a treatment method for ultrafiltration tank bottoms

Abstract

The invention relates to a special vacuum-type drum filter for treating ultrafiltration tank bottom substances and a treatment method of ultrafiltration tank bottom substances. The special vacuum-type drum filter comprises a drum drive unit, a filter tank, a drum, a distributing head and a stirring device. The special vacuum-type drum filter is characterized in that one side wall of the inner bottom of the filter tank is provided with an ultrasonic generator; one side wall of the filter tank is provided with an enzymolysis solution inlet; and the enzymolysis solution inlet is connected with an enzymolysis solution input pump. The ultrafiltration tank bottom substance treatment machine provided by the invention can directly discharge the tank bottom substances to the tank bottom treatment procedure without on-line water dilution when the ultrafiltration reaches the cleaning period, shortens the cleaning time (1.5 hours of water dilution and liftout time for each cleaning period), greatly lowers the blockage and abrasion degree of the ultrafiltration membrane by activated carbon and other solid particle auxiliary materialss, and is beneficial to prolonging the service life of the ultrafiltration membrane.

Description

technical field [0001] The invention belongs to the field of cleaning and drying equipment, in particular to a special vacuum drum filter for processing ultrafiltration tank bottoms and a treatment method for ultrafiltration tank bottoms. Background technique [0002] In the fruit juice processing process, the ultrafiltration process is completed every production cycle, and a large amount of activated carbon, fruit juice and other ingredients are accumulated in the ultrafiltration circulation tank, which is called the bottom of the tank. Since it contains a large amount of fruit juice, it is a pity to discard it and increase sewage. Treatment cost, the current treatment method is to add water to the ultrafiltration circulation tank to dilute to improve the fluidity of the bottom of the tank to ensure the normal operation of the ultrafiltration, so as to collect as much juice as possible. [0003] The disadvantages of this treatment method are: adding water to dilute takes up...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of this treatment method are: adding water to dilute takes up the cleaning and production time of ultrafiltration; adding water will increase the evaporation of the line after adding water, and increase energy consumption; the juice in the tank bottom is not fully extracted; the liquid tank bottom is discharged to the sewage station Increased difficulty and cost of sewage treatment
