Abstract

The utility model relates to a precession centrifuge. A driveline respectively drives a solid major axis and a hollow major axis to rotate and the hollow major axis drives a solid minor axis and a stepped rotary drum to autorotate through a cardan clutch. The hollow major axis drives a hollow minor axis to rotate and through the hollow minor axis drives the stepped rotary drum to revolve around a hollow major axis line. Suspension is introduced to a distributor by an ingress pipe and is added into the conelet end of the rotary drum. Under the function of centrifugal force, liquid phase is thrown out through a sieve and eyelets on the rotary drum. Solid material is moved towards the large mouth end of the rotary drum along the stepped sieve. When the solid material is moved to the fore deflecting board position of each stepped section, axial motion is changed into radial motion and the solid material is deflected to another stepped section.

Description

Precession centrifugal

The utility model relates to a kind of separation machinery, particularly a kind of tumbler centrifuge with staged rotary drum.

The present rotary drum that tumbler centrifuge adopted is common rotary drum (cone-element), the bus that is characterized in rotary drum is a skew lines, the not only rotation under transmission system drives of the rotary drum of this machine, but also revolve round the sun, this machine has stronger control ability to the motion of the solid-phase material in the rotary drum, but, because its rotary drum is the conical ring face, material under action of centrifugal force by conelet end very fast to large awl end motion, be that time of stopping in rotary drum of material is too short, the water capacity of the feasible solid-phase material of separating is bigger than normal, can not satisfy quality requirement, especially concerning requiring the very low product of water capacity, the centrifuge that adopts this rotary drum (cone-element) is inapplicable, so limited the scope of application of this centrifuge.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and a kind of residence time of material is long, tumbler centrifuge good separating effect, that have the staged rotary drum and provide.

The purpose of this utility model is to realize by following technical scheme, transmission system drives solid major axis respectively and hollow major axis rotates, hollow major axis drives solid minor axis by Hooks coupling universal coupling and the stairstepping rotary drum is done rotation, hollow major axis drives that hollow minor axis rotates and drives the stairstepping rotary drum by hollow minor axis does revolution around long heart long axis ray, suspension is incorporated into distributor by ingress pipe, and then join the conelet end of rotary drum, under action of centrifugal force, liquid phase throws away by the eyelet on screen cloth and the rotary drum, and solid-phase material moves along the big opening end of step-like screen cloth to rotary drum, when moving to the deflection plate place of each stairstepping section front portion, then change the also inflection of radially moving into to next ladder section by axially-movable.

Therefore remarkable result of the present utility model is:

Because the segmented screen cloth that has adopted the staged rotary drum and matched with it and use prolongs the motion course of material, it is effective to separate drying, has reduced the moisture content of product significantly, has improved the quality of product, has enlarged the accommodation of machine to different material.

Concrete structure of the present utility model is to be realized by following drawings and Examples:

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is Fig. 1 transfer tympanic part separation structure enlarged drawing.

Fig. 3 is the structure chart of another embodiment of the present utility model.

Fig. 4 is the structure enlarged drawing that Fig. 3 transfer tympanic part divides.

Below in conjunction with accompanying drawing 1-4 concrete structure of the present utility model is described in detail:

The utility model organic block 12, be coated with hollow major axis 4 in the bearing spider 2 that is connected with support 12, be coated with solid major axis 3 in the hollow major axis 4, solid major axis 3 is connected with solid minor axis 5 by Hooks coupling universal coupling 7, the hollow minor axis 6 of solid minor axis 5 overcoats is connected with hollow major axis 4, the two ends of the ring cavity 17 between each rotating shaft all are set with bearing 2A, solid minor axis 5 is connected with the blue seat 13 of sieve, the blue seat of sieve 13 is connected with opening drum 9 portlet, surrounding place side is provided with screen cloth 10 in the rotary drum 9, be provided with suspension ingress pipe 14 with the osculum end place of the blue seat of sieve 13 distributors that are connected 15, suspension ingress pipe 14 is fixed on the front housing 11, front housing 11 is connected with support 12, support 12 bottoms are provided with liquid phase export mouth 12A, support 12 front portions are provided with the radially baffle plate 16 of convex, hollow major axis 4 and solid major axis 3 all turn by its outer belt pulley 1 of visiting on the section, it is characterized in that, rotary drum 9 is a stairstepping, front side in each ladder section turning point is provided with deflection plate 8, deflection plate 8 is fixed on the periphery wall or rotary drum 9 of distributor 15, and deflection plate 8 all has a material movement gap 8A with the segmented screen cloth 10 anchor ring ends that turnover end face 9B and stairstepping rotary drum 9 peripheries of each ladder anchor ring 9A of stairstepping rotary drum 9 are connected.Referring to Fig. 1 and Fig. 3

Architectural feature of the present utility model also is:

Each ladder anchor ring 9A of stairstepping rotary drum 9 all is conical ring shape or horn-like, the bus of each section ladder anchor ring 9A is the curve of straight line or convex, and the torus shape that is arranged on the segmented screen cloth 10 of each section ladder anchor ring 9A outer ring is consistent with the shape of generatrix of each ladder anchor ring 9A.Referring to Fig. 2 and Fig. 4.

Architectural feature of the present utility model also is:

Stairstepping rotary drum 9 is the removable structure that monoblock type or segmentation connect, and slope or the curvature of each section ladder anchor ring 9A are identical or different, and deflection plate 8 is Circular Plate shape or cone barrel.Referring to Fig. 2 and Fig. 4

Working mechanism of the present utility model is: referring to Fig. 1.

Because the rotary drum of this tumbler centrifuge is stepped, when material movement arrived deflection plate 8, its velocity component vertically was reduced as zero, and material can only radially move.When material when deflection plate moves to the root of next ladder section by centrifugal action, in 360 degree scopes of rotary drum, can not all start simultaneously at once, and only in the tumbler centrifuge discharge zone, be to start in rotary drum semi-cone angle and nutational angle sum the zone greater than the angle of friction of material and screen cloth, and the material outside discharge zone can only wait for that entering discharge zone could start, therefore, whenever move to a step, will make a part of material stagnate, and time that is prolonged when stagnating and continued to separate and dry, therefore, can obtain fine separating effect, be particularly suitable for the separation that water capacity requires low product.
