Description
The utility model relates to the used mud juice filtration device in a kind of equipment that liquid is separated, especially sugar refinery from solid.
The clarification filtration of sugarcane juice is as the important technical process in sugar refinery, and its main effect is as far as possible the field trash that is mixed in the sugarcane juice to be separated from sugarcane juice.Sugar part of also containing certain deal in the mud juice that clarifying process produces by the form of filtering, is regained sugared part that remains in the mud juice as far as possible, makes the sugared part of losing in filter mud be reduced to bottom line, the productivity ratio of raising sugar.
For a long time, the mud juice filtration equipment that China adopts in nearly all sugar refinery is traditional have filter cloth vacuum suction filter and plate and frame filter press, these equipment are equipped with as the standard of sugar refinery mud juice filtration equipment, in the sugar industry of China is produced, used considerable time, also made bigger contribution for the sugar industry production of China.But these equipment exist following shortcoming in the production use: the mud juice disposal ability of first equipment is limited, and equipment needed thereby platform number is many, and equipment investment is bigger; It two is pol (contain sugar part) height of the filter mud that produces, and sugar part loss is serious; It three is to filter used filter cloth to want frequent disassembly, cleaning, labor strength is big, more seriously a large amount of waste water of filter wash cloth generation efflux, serious environment pollution, along with country in recent years to the pay attention to day by day of environmental issue, how when guaranteeing enterprise's ordinary production, can guarantee the product quality and the quantity in sugar refinery, can guarantee again to efflux the pollutant qualified discharge, become a difficult problem of puzzlement sugar refinery enterprise development.
The purpose of this utility model provides a kind of no filter-fabric vacuum mud juice filtration device, it should be able to reduce the pol (containing sugar part) of filter mud that mud juice filtration is arranged greatly, improve the disposal ability of filter mud unit's filter area, alleviate labor intensity of operating personnel, fundamentally eliminate a large amount of waters of filter wash cloth in sugar refinery, make sugar refinery reduce by big pollution sources.
The utility model comprises that being provided with supporting shaft is provided with the rotary drum cylinder of inhaling the juice conduit with the inboard, suction juice conduit wherein, the rotary drum cylinder outer surface communicates with the vacuum dispensing head that is located at supporting shaft one end, and rotary drum transmission device, mud juice groove, agitating device, heat water-spraying's device, cleaning shoe device and frame, be characterized in:
(a) outer surface at described rotary drum cylinder fixedly is coated with grid and ultra-thin stainless steel micro porous filtration net, and wherein grid is between this cylinder outer surface and the micro porous filtration net;
(b) contain at described rotary drum cylinder supporting shaft that to inhale the vacuum dispensing head that juice conduit one end connected be the vacuum dispensing head that is provided with three function divisions of low vacuum district, high vacuum region and atmospheric area, low vacuum district and high vacuum region communicate with separately conduit and basin respectively.
On the outside of described rotary drum cylinder, be divided into many equal portions by circumference, on every equal portions, be fixed with U type groove longitudinally, the Zhou Guoyong rubber strip of ultra-thin stainless steel micro porous filtration net is pressed abd fixed in each U type groove.
The no filter-fabric vacuum mud juice filtration device of said structure, the rotary drum cylinder crouches in the mud juice groove, and the rotating shaft at two ends is by the bearing block support on the frame; The transmission device of rotating cylinder is passed to the rotary drum cylinder at an end of frame with power, makes its rotation; Agitating device is arranged on rear side one end of mud juice groove, by continuous swing be located in the mud juice groove, agitator below the rotary drum cylinder, prevent the mud juice precipitation, separate the concentration stabilize of mud juice in the protection mud juice groove with the sugarcane chaff with mud juice; Heat water-spraying's device is located at the rear and the top of rotary drum cylinder, be provided with many spray pipings and rotary drum drum surface parallel longitudinal, on the every pipeline face relative with the rotary drum cylinder, dispose several water spouts, can form spurting to hot water during operation, spray equably on the filter mud of rotary drum drum surface, dissolve the residual sugar part in the filter mud, be beneficial to the vacuum absorption of juice sucking tube net in the rotary drum cylinder; The cleaning shoe device is located at the front of rotary drum cylinder, is fixed on the top, the outside of mud juice groove, and its effect is that filter mud is scraped from the rotary drum drum surface.Like this, the rotary drum cylinder constantly rotates under the driving of transmission device, it is online that filter mud in the mud juice groove is adsorbed on the ultra-thin stainless steel micro porous filtration of rotary drum cylinder outer surface, sugar part in the filter mud is dissolved through the heat water-spraying,, in basin, contained sugar part filter mud seldom and scraped by the juice sucking tube net vacuum absorption in the rotary drum cylinder by cleaning shoe.So circulate and constantly the filter mud in the mud juice groove is filtered, draw sugar part, the venting filter mud.Certainly, need the filter mud of filtration also constantly from the clarifying process of sugarcane juice, constantly to be injected in the mud juice groove.Whole process is automatically carried out, and has removed the operation of manually unpicking and washing filter cloth from, has saved the water of a large amount of filter wash cloth, has eliminated pollution sources, has improved the disposal ability of equipment filter mud unit filter area, has also improved sugared productivity ratio.
