Summary of the invention
The utility model is realized with following technical scheme.
The spiral slag-draining device of horizontal spiral discharge sedimentation centrifuge, it is made up of circular cone rotary drum, the little end cap of rotary drum, auger conveyor, bearing, sealing ring and ring flange, on ring flange, is fixed with scraper, ring flange by screw attachment on auger conveyor.Be contained in scraper on the ring flange peripheral wall a slice to four slice is arranged.
This apparatus structure is compact, easy for installation, maintenance and operation is simple, and it is effective that the scraper cutter is scraped the solid phase particles accumulation, effectively protects sealing ring and bearing safety, not worn and torn by solid phase particles, guarantees that machine normally moves.Present technique is suitable for horizontal spiral discharge sedimentation centrifuge and uses.
Description of drawings
The structural representation of the spiral slag-draining device of Fig. 1 the utility model horizontal spiral discharge sedimentation centrifuge.
Fig. 2 is fixed with the flange plate structure front view of scraper.
Fig. 3 is the side view of Fig. 2.
Fig. 4 the utility model is at horizontal spiral discharge sedimentation centrifuge user mode sketch map.
The specific embodiment
In conjunction with accompanying drawing the utility model is done further explain.
Horizontal spiral discharge sedimentation centrifuge is made up of cylinder rotary drum 11, circular cone rotary drum 10, auger conveyor 5, feed pipe 8, big-end bearing seat 2, little-end bearing seat 7, ring flange 19, ring flange 20, scraper 4, differential mechanism 1, drive disk assembly and support 6, casing 3 etc.
Divide the several sections explanation below
(1) rotary drum part.
Form by the big end cap of circular cone rotary drum 10, cylinder rotary drum 11, rotary drum 12, rotary drum small end lid 13 etc.Big end axial distribution at rotary drum has six fluid holes 14, and liquid level is by adjustable plate 15 controls.For adapting to the needs of the different mass dryness fractions of various different materials and solid phase, this machine is regulated the liquid level size through the different overflow radiuses of changing adjustable plate 15, and the R value is big more, and the decanting zone is short more, and dry section is just long more, and the solid phase of separating is also just dried more; Otherwise the decanting zone is long more, and the solid content of the liquid phase of separating is just few more, and solid phase also phase strain is wet.The small end of rotary drum is radially distributed with eight solid phase outlets 16 that stud with anti-wearing liner.
(2) auger conveyor part.
Main inner core 17, blade 18 and ring flange 19 by the post taper, ring flange 20 etc. are formed.Blade 18 is welded on and becomes spiral yarn shaped on the inner core 17, and the cylindrical of leaf 18 and pusher front are sprayed with one deck wearable hard alloy layer, and abrasion resistance is good, can repair after the sprayed coating wearing and tearing.There is cloth acceleration cone 22 at spiral discharging mouth 21 places, get into the rotary drum working chamber again after material is accelerated to the rotary drum rotating speed in advance, to reduce the impact of material to liquid pool.
(3) differential mechanism part.
This machine adopts 2K-H satellite differential 1, and transmission efficiency is high, reliable operation and compact conformation.Its cylindrical and rotary drum are done rotation synchronously, and output shaft drives augur.This machine has adopted after it, has guaranteed that rotary drum and auger conveyor rotate with different speed in the same way, and can obtain stable slip value.Tail end at differential mechanism is provided with Machine guarding, if auger conveyor pusher resistance is excessive, can throw off the driving coupling between differential mechanism and the auxiliary motor automatically, prevents that differential mechanism from damaging.
(4) running part.
Drive motors adopts common electric machine distribution transforming speed regulator frequently, and motor is regulated different centrifuge working speeds according to material characteristic, after differential mechanism power shaft 24 is fixed by overload protection arrangement 23, thereby makes rotary drum and spiral produce the difference rotating speed.
(5) scraper part.
Auger conveyor 5 is with sealing ring 25 sealings between itself and rotary drum small end cover 13 in bearing 9 is bearing in circular cone rotary drum 10.Two scrapers 4 fixedly are equipped with in welding on ring flange 20 peripheral walls, and ring flange 20 is connected on the auger conveyor 5 by screw 26.Sheet scraper 4 is the periphery that symmetric position is arranged in ring flange 20.
Operation principle
The horizontal spiral discharge sedimentation centrifuge of the utility model is by two motor-driven, and main motor drives rotary drum through belt and the differential mechanism shell rotates, and auxiliary motor is through differential mechanism speed change rear drive spiral.Rotary drum and spiral are rotated in the same way and have certain poor rotating speed.
When suspension gets into the auger conveyor inner chamber, after acceleration cone is quickened, flow out from discharging opening, flow to drum inner wall.Form the weight phase of suspension, owing to receive different centrifugal forces, the heavy phase fast deposition and gently attaches to the heavy phase surface mutually to drum inner wall, and weight has formed one deck interface between mutually.Along with increasing of heavy phase deposition; Helical blade 18 tops get into the heavy phase sedimentary deposit, rotary drum and auger conveyor rotation at a high speed just in the same way at this moment, and certain difference is arranged; This relative mistake rotating speed makes the heavy phase particle move to the small end discharging opening; And light through helical duct, flow to big end liquid phase exit, flow out through overflow plate.Liquid phase overflow radius is controlled by adjustable plate.
After solid phase particles deposits in rotary drum; Be under the promotion of auger conveyor 5, to discharge from rotary drum small end solid phase outlet 16, auger conveyor 5 leans on bearing 9 to be bearing in the rotary drum 10, and sealing was a rubber seal 25 between itself and rotary drum small end covered 13; When solid concentration is higher can not in time discharge rotary drum the time; Solid phase particles is pushed to rubber seal 25 places through the gap between auger conveyor 5 and the rotary drum small end lid 13 easily, and before not installing scraper 4 additional, rubber seal 25 is easy to wear out failure after running into solid phase particles; Solid phase particles gets in the bearing 9 can cause damage of bearings, thereby causes machine vibration and can not turn round.
After the improvement, increased scraper 4 at small end ring flange 20 places of auger conveyor 5, sheet scraper 4 is welded on the ring flange 20; Ring flange 20 is to be connected on the auger conveyor 5 with screw 26; When auger conveyor 5 relatively rotated the discharge of promotion solid phase particles in rotary drum 10, scraper 4 just can be forced the solid phase particles that is extruded onto circular cone rotary drum 10 awl ends to scrape, and avoids the solid phase particles accumulation; Thereby effectively protect rubber seal sealing and bearing, improved the machine reliability of operation greatly.
