Description
Technical field:
The utility model cylindricality rotating cylinder centrifuge is used for sludge water is carried out mud-water separation, belongs to the environmental protection machinery apparatus field.
Background technology:
The rotating cylinder of the discrete heart water extracter of China's production at present is the awl cylindricality, be that the centrifugation section is a cylindricality, the mud extraction section is taper, and the solid mud after the centrifugation is under the conveying of internal helicoid, move to taper rotating cylinder section by cylindricality rotating cylinder section, at this moment, the separation factor of straight section is equal, but after solid mud enters the commentaries on classics of taper rotating cylinder, then separation factor reduces gradually, and in order to make conveying solid substance mud easy, bevel angle is just done lessly, so just brings following shortcoming:
1, makes the volume of bevel angle clarification liquid layer less, thereby reduced the processing power of whizzer.
2, because the particle of active sludge is very little, be difficult to separate, after cone angle reduces, when mud moves to exit end, can make fine particle that trend in the liquid phase of coming back to is arranged, be unfavorable for the separation of subparticle, the sewage sludge solid rate of recovery is reduced.
3, the conical section requirement on machining accuracy height of awl cylindricality rotating cylinder has increased manufacturing cost.
In order to remedy above shortcoming, the company that has has adopted some innovative approachs, adopts short cone-shaped body, and the distance of lengthening settling section has improved the processing power of whizzer; Perhaps simply adopt the structure of bipyramid, the centrifugation section that is rotating cylinder makes cone-shaped into by cylindricality, separate terminal separation factor thereby strengthen, and make the volume of settling section bigger, the processing power of whizzer and the mass dryness fraction of solid mud have been improved, more than two kinds of ways can receive better effects undoubtedly, but processing, cost of manufacture are significantly risen, thereby influence competitiveness of product.
Summary of the invention:
The purpose of this utility model provides a kind of cylindrical drum centrifuge, replaces original awl cylindrical drum, with the mud and the water sepn of sludge water, thereby obtains the maximum separation factor and the volume of settling section, and processing is separated easily, and cost reduces.
A kind of by advancing mud pipe (1), drive unit (2), outer gland (3), bearing (4), bearing support (5), front end end cover (6), regulating weir (7), rotating cylinder body (8), internal gland (9), bearing (10), screw shaft (11), spiral conveyer (12), cover plate (13), scraper (14), rear end cap (15), transmission shaft (16), the cylindricality rotating cylinder centrifuge that oil motor (17) and support (18) are formed, it is characterized in that: advance mud pipe (1), bearing support (5) and oil motor (17) are fixed on respectively on the support (18), advance mud pipe (1) exit end and stretch in screw shaft (11) cavity; Drive unit (2) links to each other with front end end cover (6), outer gland (3) is fixed in bearing support (5) with bearing (4), bearings at both ends (4) supports front end end cover (6) shaft shoulder and rear end cap (15) shaft shoulder respectively, front end end cover (6) is connected with rotating cylinder body (8) at two ends respectively with rear end cap (15), regulating weir (7) is fixed in front end end cover (6) water outlet, screw shaft (11) is bearing in bearing (10), internal gland (9) solid bearing (10); Spiral conveyer (12) is mounted to one with screw shaft (11), and scraper (14) is fixed in screw shaft (11); Cover plate (13) covers on outside the rotating cylinder body (8); Transmission shaft (16) left end links to each other with screw shaft (11), and right-hand member links to each other with the shaft of oil motor (17).
The principle of work and the operational process of this cylindricality rotating cylinder centrifuge are described as follows:
When drive unit rotates, can drive the front end end cover rotation, thereby drive the rotation of rotating cylinder height speed; On the other hand, can drive the screw shaft high speed rotating during oil motor operation, at this moment, this centrifuge just is in the high-speed cruising state.
The material sludge water is imported in the mud pipe by pump, then, enters in the cavity body of screw shaft; Under centrifugal action, sludge water is entered in the rotating cylinder body cavity by the aperture in the spiral axocoel, because the proportion of mud and water is different, under the high speed centrifugation effect of rotating cylinder body, it is two-layer to be divided into tangible solid, liquid, mud is close to the inwall of rotating cylinder body, and water is in the mud inboard, when water level surpasses regulating weir, then discharge from centrifuge, the solid mud of being close to the rotating cylinder body wall after the dehydration then travels forward under the promotion of spiral conveyor, struck off to the scraper place and discharge centrifuge, thereby the solid, liquid two-phase of having realized sludge water separates.
Description of drawings:
Fig. 1 is the one-piece construction synoptic diagram of this centrifuge.
Among the figure: 1 for advance the mud pipe, 2 for drive unit, 3 for outer gland, 4 for bearing, 5 for bearing support, 6 for front end end cover, 7 for regulating weir, 8 for the rotating cylinder body, 9 for internal gland, 10 for bearing, 11 for screw shaft, 12 for spiral conveyer, 13 for cover plate, 14 for scraper, 15 for rear end cap, 16 for transmission shaft, 17 for oil motor, 18 for support.
Embodiment:
Referring to Fig. 1: drive unit 2 is rotated by the motor drives belt pulley, drive unit 2 is with after front end end cover 6 links to each other, because of front end end cover 6 and rear end cap 15 all link together with some bolts and rotating cylinder body 8, like this, front end end cover 6 just passes torque to rotating cylinder body 8, just make from the sludge water of the aperture in screw shaft 11 chambeies and in rotating cylinder body 8, make high speed rotating, carry out centrifugation, the solid sludge blanket that forms at rotating cylinder body 8 inwalls then, promoted to travel forward by spiral conveyer 12, strike off by the scraper 14 that has angle to the exit, thereby fall in the solid mud relief outlet, and be positioned at the water of solid sludge blanket inboard, then on regulating weir 7, flow out centrifuge.
Advance mud pipe 1 left end and be fixed in support 18, advancing mud pipe 1 right-hand member is exit end, install always and extend in the hollow lift-off of screw shaft 11, the bearing support 5 at left and right two ends uses bolting respectively on left and right support 18, left and right two ends are fixed in left and right bearing 4 on the left and right bearing support 5 with outer gland 3 respectively, their shaft shoulder of front end end cover 6 and rear end cap 15 is bearing in respectively on the left and right bearing 4, at left and right two ends, front end end cover 6 and rear end cap 15 are connected rotating cylinder body 8 with some bolts respectively again, and regulating weir 7 usefulness bolting are on the water outlet of front end end cover 6.
Screw shaft 11 two ends are by left and right bearing 10 supportings, and left and right two internal glands 9 are fixed left and right bearing 10 respectively, and spiral conveyer 12 is welded on screw shaft 11 outsides; Cover plate 13 covers on the rotating cylinder body 8, mainly plays safety effect; Scraper 14 is fixed by bolts to screw shaft 11 right-hand members.
Rotating speed between the rotating cylinder body 8 of high speed rotating and the screw shaft 11 of high speed rotating has certain difference, differs 5～20 rev/mins approximately.
The structure of above-mentioned cylindricality rotating cylinder centrifuge can obtain the volume of maximum centrifugal separation factor and settling section, and simultaneously, processing and manufacturing is that cylindricality becomes easily because of structure, and cost has also reduced.
