Description
Technical field
The utility model relates to a kind of rotary drum pumping equipment that rotary the rotary drum centrifuge, particularly horizontal spiral discharge sedimentation centrifuge of auger conveyor are arranged.
Background technology
Horizontal spiral discharge sedimentation centrifuge is to utilize to have different densities and immiscible light, heavy-fluid and solid phase in the mixed liquor, in centrifugal force field, obtains the principle of different sinking speed, reaches the purpose of separating layering or making solid particles sediment in the liquid.Centrifuge is in the process of separation of material, and solid phase particles moves discharge to the small end discharging opening, and light phase (liquid) flows to outside the big end liquid phase outlet discharge machine through helical duct.Existing this type of centrifuge discharge opeing ring flange is the ring flange of through type eccentric orfice adjustable plate; Clear liquid directly washes away casing when the outside flat raft of the big end of rotary drum goes out; Liquid splashes easily and leaks into the casing outside from the gap location of rotating shaft and casing labyrinth seal, and environment is polluted.
Summary of the invention
The utility model is realized with following technical scheme.
The rotary drum pumping equipment of horizontal spiral discharge sedimentation centrifuge, it is made up of cylinder rotary drum, the big end cap of rotary drum and auger conveyor, has the adjustable plate of through hole to be packed on the big end cap with screw, and adjustable plate is connected with barrier plate.The position of barrier plate shelters from the adjustable plate partial through holes.Barrier plate and adjustable plate manufacture one, or join together with welding or with screw is affixed.
The utility model is simple in structure, compact, and operation and maintenance is convenient, can stop effectively that flow liquid splashes to go out, and the gap location between rotating shaft and the casing labyrinth seal effectively prevents the past from here external leakage of liquid, prevents because of the leakage liquid contaminated environment.Present technique is suitable for spiral discharge sedimentation centrifuge and uses.

Fig. 2 adjustable plate and barrier plate draw bail master look sketch map.
Fig. 3 is the side view of Fig. 2
Fig. 4 the utility model is at horizontal spiral discharge sedimentation centrifuge user mode structural representation.
The specific embodiment
In conjunction with accompanying drawing the utility model is done further explain.
Horizontal spiral discharge sedimentation centrifuge is made up of circular cone rotary drum 10, cylinder rotary drum 11, auger conveyor 5, feed pipe 8, big-end bearing seat 2, little-end bearing seat 7, adjustable plate 9, barrier plate 15, differential mechanism 1, drive disk assembly and support 6, casing 3.
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.Big end axial distribution at rotary drum has six fluid holes 14, and liquid level is by adjustable plate 9 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 9, 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 liquid phase solid content 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.
Mainly contain the composition such as inner core 17, blade 18 and ring flange 19, ring flange 20 of post cone.Blade 18 is welded on and becomes spiral yarn shaped on the cylindrical shell 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 25, thereby makes rotary drum and spiral produce the difference rotating speed.Motor is stamped motor shield 4.
(5) adjustable plate and barrier plate part.
On the big end cap 12 of rotary drum, adjustable plate 9 and barrier plate 15 are housed, present embodiment adjustable plate 9 manufactures one with barrier plate 15, passes the hole 28 of adjustable plate 9 with screw 23, and adjustable plate 9 and barrier plate 15 are fixed on the big end casing 12 of rotary drum together.Adjustable plate 9 has the position of through hole 27. barrier plates 15 to block the partial through holes 27 of adjustable plate 9.
Operation principle
The horizontal discharging 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, and this is rotary drum and auger conveyor rotation at a high speed just in the same way, 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 the outlet of big end liquid phase, flow out through overflow plate.Liquid phase overflow radius is controlled by adjustable plate.
On the big end cap 12 of rotary drum, adjustable plate 9 and barrier plate 15 are housed, the hole 28 of passing adjustable plate 9 with screw 23 is fixed on adjustable plate 9 and barrier plate 15 on the big end cap 12 of rotary drum together, thereby has formed a right angle channel; Clear liquid from the big end of rotary drum when the through hole of adjustable plate 9 27 is discharged; Because barrier plate 15 has changed the flow direction of liquid, clear liquid is to throw away outwardly along the rotary drum radial direction, can not splash to labyrinth seal 26 places; Thereby effectively prevented the clear liquid leakage phenomenon, protected environment.
