Abstract
The invention discloses a bell jar device of a centrifuge used for mineral separation in coal preparation plants. By adopting the bell jar device, a back-out material can be locked by self on the surface of the bell jar device, that is, the included angle between the normal of a contact surface or the normal of the connecting line of two protruding points and the movement direction of the material is smaller than a friction angle between the material and the contact surface or between the material and another material. The bell jar device is reasonable in structure, long in service life, good in portability, and easy to mount.
Description
Technical field
The present invention relates to a kind of centrifuge, particularly ore dressing, the bell jar of coal preparation plant's centrifuge.
Background technology
Bell-jar is the base of centrifugal machine sieve basket, and it is made up of terminal pad, clock body, basket seat, contact surface.The contact surface of existing bell-jar is an abundant up-small and down-big taper seat foundry goods; The cone angle of taper seat can not make the material self-locking in its surface of back-out, both the angle folded by the direction of motion of taper seat normal and material was greater than the angle of friction of material and the conical surface, produced and slided, cause wearing and tearing, its life cycle is shortened, and simultaneously abundant taper seat is also very heavy.
Summary of the invention
The technical problem to be solved in the present invention is: the deficiency overcoming background technology, provides a kind of rational in infrastructure, lightweight, the bell jar do not worn and not torn.
Concrete scheme of the present invention is: in the bell-jar be made up of terminal pad, clock body, basket seat, contact surface, it is characterized in that described contact surface can allow screw out material self-locking in its surface, both the normal of contact surface normal or contact surface two projecting point line and the angle folded by material movement direction were less than the angle of friction between material and contact surface or between material and material.Described contact surface can be taper seat, also can be the surface of other shape; The surface of other shape described can be the surface of a closed-in construction.
The present invention has advantage rational in infrastructure, to wear and tear little, light, easy installation.
Accompanying drawing explanation
Fig. 1, Fig. 2 are the profile of this device, and Fig. 3, Fig. 4 are the enlarged drawing of Fig. 1, Fig. 2 contact surface respectively.
Below in conjunction with accompanying drawing, the present invention is described further.
Detailed description of the invention:
Implement 1: see Fig. 1, Fig. 3, in the bell-jar be made up of terminal pad 1, clock body 2, basket seat 3, contact surface 4, contact surface 4 can allow the material screwed out in its surperficial self-locking, and both the normal 5 of contact surface 4 and the angle 7 folded by the direction of motion 6 of material were less than the angle of friction of material and contact surface.When material revolves, material is self-locking in contact surface 4 surface, and during to certain thickness, taking angle of friction as the material back-out that boundary is greater than angle of friction, the material being less than angle of friction stays and does protective layer.
Implement 2: see Fig. 2, Fig. 4, in the bell-jar be made up of terminal pad 1, clock body 2, basket seat 3, contact surface 4, contact surface 4 is surfaces of other shape, be the surface of a closed-in construction, upper cover inner 8 and the normal 5 of line 10 of the inner 9 of going to the bottom and the angle 7 folded by material movement direction 6 of closed-in construction are less than the angle of friction between material and material.When material screws in, first closed-in construction is full of, after with the angle of friction between material and material for boundary screws out.
Claims (4)
1. a centrifuge, particularly ore dressing, the bell jar of coal preparation plant's centrifuge, at one by terminal pad (1), clock body (2), basket seat (3), in the bell-jar that contact surface (4) forms, it is characterized in that described contact surface (4) can allow screw out material self-locking in its surface, both the normal (5) of contact surface (4) or the normal (5) of contact surface (4) two projecting point line (10) and the angle (7) folded by material movement direction (6) were less than the angle of friction between material and contact surface (4) or between material and material.
2. contact surface according to claim 1 (4), is characterized in that described contact surface (4) is taper seat.
3. contact surface according to claim 1 (4), is characterized in that described contact surface (4) is other shape face.
4. the contact surface (4) according to claim 1 or 3, is characterized in that other described shape face are surfaces of a closed-in construction.
