Description
Technical field
The present invention relates to a kind of doctor blade device of centrifuge, particularly relate to the remaining cake layer device of removing on a kind of centrifugal machine scraper.
Background technology
Discharge way classification pressed by centrifuge, manual unloading centrifuge can be divided into, gravity discharging centrifuge, centrifuge with cutter discharge of solid, piston push centrifuge, helical-conveyer centrifugal, centrifugal discharging type centrifugal machine, vibration discharging centrifugal machine, material discharge centrifuge, wherein centrifuge with cutter discharge of solid operation is indirect, and operation automatically, generally uses.
The rotary drum of centrifuge is when high-speed rotation works, scraper is collapsed state, when rotary drum is adjusted under lower-speed state, scraper is slowly near rotatory drum wall, be deep into material cake layer, progressively the solid material after centrifugation in rotary drum is scraped and chip away, scraper is inactive state relative to the earth, during work, side-to-side movement is there is and moves up and down in scraper relative to rotatory drum wall, scraper can not unrestrictedly close to rotary drum, the remaining bed of material that generally can there are 10 to 15 millimeter cannot be peeled off automatically, artificial removing can only be relied on, Chinese patent 103128006A discloses the scraper of band filter cake crushing device, in scraper discharging process, cake layer can be ground, it peels off by the mouth of air-blowing simultaneously ejection gases at high pressure automatically, Chinese patent 103128006A is for industry staff, there is following shortcoming:
(1), in patent 103128006A description, write wing 3 arranged outside air-blowing mouth 4 exactly, while grinding, air-blowing mouth 4 sprays gas, is blowed by the bed of material being difficult to grind, and this kind of technical scheme is difficult to realize, the method removing cake layer air-blowing should be select inverse air-flow blowback, generally be used on pocket type centrifuge, drying in front, should produce the blowing force to rotatory drum wall direction, play the effect of rotatory drum wall, falling-off effect is not obvious.
(2), bowl is column type, but when containing remaining cake layer, rotary drum is not just cylindrical shape completely, but irregular shape, patent 103128006A wing afterbody is provided with support, support one end is connected with mount pad, it is characterized in that described wing arranged outside has air-blowing mouth, mount pad two ends are provided with roller, the position of support on wing is adjustable, air admission hole is provided with in the middle of scraping cutter bar, although the position of support on wing is adjustable, just when rotary drum stop motion, can regulate, can not regulate in the course of work, when bowl slowly runs, the length of scraper support and wing is around drum rotating, because there is remaining filter cake, scraper is not a fixed number numerical value to the distance of rotatory drum wall filter cake, part doctor blade is just caused not reach remaining filter cake surface, do not have the object eliminating remaining filter cake.
(3), patent 103128006A discloses wing afterbody and is provided with the broken roller of filter cake, in scraper discharging process, cake layer can be ground, merely disclose idea, not specific embodiments, want to make roller play fragmentation, roller and rotatory drum wall close contact must be made, rotary drum can not be destroyed because of the active force between roller and rotatory drum wall again simultaneously.
(4), patent 103128006A, scraper and moving up and down of rotatory drum wall are not disclosed, the just horizontal movement of scraper and rotatory drum wall, a kind of embodiment that just scraper height is identical with rotatory drum wall height, does not describe scraper height and is less than the high situation of rotatory drum wall wall.
Summary of the invention
The object of this invention is to provide the remaining cake layer device of a kind of removing, the problem that the remaining cake layer that can solve centrifuge material cannot be removed automatically.
The present invention solves the problem that remaining cake layer removes automatically and realizes by the following technical solutions, a kind of device removing remaining cake layer comprises base, cutting wheel, support, spring and scraper plate, wherein base to be placed on wing and to be fixedly connected with wing, connected mode removes the device pedestal of remaining cake layer and wing is integrated, or be screwed between base and wing, fixed support on the base seat removing remaining cake layer device, cutting wheel and scraper plate, cutting wheel is connected with base by cutting wheel power handle, support is fixed on base or support is fixed on scraper arm, spring is provided with between described cutting wheel and support, elastic force due to spring makes cutting wheel near drum inner wall, when scraper, because rotary drum rotates, rotary drum produces outer shear force for cutting wheel, the object of spring remains that cutting wheel contacts with rotatory drum wall, the pressure adjustable of spring, make cutting wheel all the time on rotatory drum wall, base and the cutting wheel of scraper driving device do relative motion in rotary drum, the wing of scraper plays removes cake layer effect, because wing and rotary drum have 5-10 millimeter gap, remaining cake layer can be produced, the present invention is the device removing remaining cake layer, wherein cutting wheel plays the effect of broken remaining filter cake, base is also provided with scraper plate, scraper plate head is that elastomeric material is made, scraper plate adds that scraper head length is greater than the distance that the base removing remaining cake layer arrives rotatory drum wall, scraper plate head is close on rotatory drum wall all the time, for the remaining filter cake that cutting wheel cutting loosens, scraper plate plays removing function, really achieve automatic operation, reduce the labour intensity of workman, remaining filter cake is discharged to outside centrifuge by material outlet.
A kind of optimal technical scheme, cutting wheel is hard material, and as stainless steel, Hastelloy forms, and its objective is and plays broken remaining filter cake effect.
A kind of optimal technical scheme, described scraper head is elastic plate, as PVC plastic, colloid plastics.
The present invention removes remaining cake layer device by installing additional at wing, really can achieve automatic operation, improve the separative efficiency of centrifuge, reduce the labour intensity of workman.
