Description
Technical field
It the utility model is related to a kind of centrifuge, and in particular to a kind of bag-filter type centrifugal machine using scraper discharging.
Background technology
Scraper discharging formula centrifuge can be divided into vertical unloading under scraper centrifuge according to the installation direction of centrifuge principal axis
(main shaft is perpendicular to ground) and horizontal type scraper centrifuger (main axis parallel is in ground).Due to wing and filter bag (or filter screen) it
Between gap presence, so, no matter from which kind of scraper discharging formula centrifuge, the problem of remaining filter cake influences filter effect, is all the time
In the presence of.
For vertical scraper centrifugal machine, occurs a kind of pulling bag device in recent years, using installed in main shaft bottom or upper end
Cylinder or oil cylinder, the piston of cylinder or oil cylinder, drive connection device, drive filter bag lower end to be axially moved, so as to realize
The discharging of remaining filter cake.But the device is realized by being axially moved, it is desirable to the rotary drum inner chamber of centrifuge, is had necessarily
Space is axially moved, so the scope of application is narrower.
Particularly horizontal type scraper centrifuger, from foreign countries be born since, always with full speed running, high speed scraper, format high throughput,
The advantages of yield is high, widely used in industries such as starch, chlor-alkalis.But because remaining filter cake influences asking for filter effect
Topic, up to the present, also without suitable method and apparatus, remaining filter cake is removed, so limiting horizontal type scraper centrifuger
Use.
In the separation process of many materials, remaining filter cake plugs filter bag, so as to which the influence to later separation is very big, leads
Cause the rate of filtration and efficiency to substantially reduce, or even can not filter.Must be continually cumbersome by manual cleaning remnants filter cakes, process
And it is unfavorable for the health of worker.
Therefore, the cleaning problem of remaining filter cake annoyings user, manufacturing firm and brainstrust always.In view of above-mentioned original
Cause, many clients be often forced from operate it is complex cumbersome, it is necessary to by electric block and manually-operated Pig from
Scheming.
In the prior art, Chinese patent, application number：CN201610115448.7, notification number：CN105562220A, title
For " a kind of remaining filter cake remove device of scraper type centrifuge ", a kind of centrifuge is disclosed.The centrifuge include be arranged on from
The rotary flange disk of scheming rotary drum inner bottom part, rotary flange disk fit with bowl bottom, and rotary flange disk
Outer rim is connected with the filter bag bottom inside centrifuge, and centrifuge principal axis is internally provided with interior axle, relative between interior axle and main shaft
Independent, one end of interior axle is connected with rotary flange disk, and the other end of interior axle is with that can drive the driving that interior axle turns an angle
Device is connected.It removes the remaining filter cake on filter bag by the way of torsion, filter bag is not only departed from the interior of rotary drum stack shell
Wall, and fold is produced, filter cake is come off, so as to remove the remaining filter cake on filter bag.The purpose of this centrifuge is using soft
Property filter bag wide-angle bending, by the material being adhered to each other against the separation force of water squeeze dissipate, make to come off.But this
Kind mode, the structure used is extremely complex, and the use of two aspects is done in same rotating shaft, and control difficulty is big, and later maintenance is inconvenient.
In addition, the material for blocking filter bag filter opening is really to be adhered to filter bag surface and the particle being present in filter bag filter opening, and this side
Formula, can only typically dispose it is thicker material bed, it is excessively poor for being adhered to the elimination effect of material particles on filter bag surface, it is right
It is limited in the effect that follow-up centrifugal filtration is played.
