Description
Technical field
The utility model relates to a kind of spiral liquid phase clarifier 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.Solid particle in the liquid flows in the rotary drum from spiral material logical sequence and begins sedimentation; Discharge from the big end of rotary drum until liquid phase; Solid particle is a point point deposition in this process; Wherein big particle deposition is very fast, and the fine particle deposition is slower, has the parts of fine microparticle can have little time sedimentation and discharges rotary drum with the liquid phase body.The spiral discharge sedimentation centrifuge that uses at present can't solve the exigent needs of liquid phase solid content, and can influence the disposal ability of machine.
Summary of the invention
The utility model is realized with following technical scheme.
The spiral liquid phase clarifier of horizontal spiral discharge sedimentation centrifuge; It is made up of cylinder rotary drum, the big end cap of rotary drum, auger conveyor and the big end cylindrical shell of spiral; The limit pendular ring is packed in the end of the big end cylindrical shell of spiral; The limit pendular ring is annular in the form of sheets, and its external diameter is littler than the internal diameter of cylinder rotary drum, and limit pendular ring middle part has through hole to be enclosed within on the big end cylindrical shell of spiral and installs.
It has simple in structure, compactness and good separating effect, and production capacity is big, and adaptability is good, can clarify the different various materials of rerum natura, characteristics such as dehydration, progressive operation.The utility model more helps the fine particle deposition, has improved the separating property of machine greatly, can improve treating capacity about 20%, can solve and satisfy the user to the demanding needs of liquid phase solid content.Present technique is applicable to horizontal spiral discharge sedimentation centrifuge.
Description of drawings
The structural representation of the spiral liquid phase clarifier of Fig. 1 the utility model horizontal spiral discharge sedimentation centrifuge.
Fig. 2 limits the pendular ring structural front view.
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 the big end cylindrical shell of circular cone rotary drum 10, cylinder rotary drum 11, auger conveyor 5, spiral 4, limit pendular ring 9, feed pipe 8, big-end bearing seat 2, little-end bearing seat 7, 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.
(2) 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 auger conveyor 5 and rotates.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 1 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) limit pendular ring part.
Operation principle
Horizontal spiral discharge sedimentation centrifuge 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 auger conveyor.Rotary drum and auger conveyor are rotated in the same way and have certain poor rotating speed.
In suspension gets into auger conveyor 5 chambeies, after acceleration cone 22 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; Spiral leaf 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.
The utility model has increased limit pendular ring 9 on the big end cylindrical shell 4 of spiral, the limit pendular ring 9 of toroidal is welded on the big end cylindrical shell 4 of spiral.Liquid in rotary drum in big end process of flowing; Liquid flow direction no longer is a level; But oblique drum inner wall direction, solid particle also is towards drum inner wall when moving with liquid like this, helps the fine particle deposition more; Improve the separating property of machine greatly, can improve treating capacity about 20%.
