Abstract
The utility model discloses a kind of spin vibration sieve screen frame and the sealing structure of rack, it includes upper and lower screen frame, the edge of upper screen frame and lower screen frame along whole circumference direction stretch out depression re-extend composition one bending sealing surface, the sealing ring is placed in bending sealing surface, boss on sealing ring falls into the recess of bending sealing surface, male-female engagement is surrounded and extruded, and on the screen frame with bending sealing surface, upper screen frame and lower screen frame are firmly squeezed on sealing ring beam ring beam.The shape of cross section at upper screen frame and lower screen frame edge is in Ω shapes, and rack is placed in the middle of upper and lower screen frame and is sealed with sealing ring, and the bending sealing surface is a ring muscle for circle.The technical program simple structure, it is easy to use, it is ensured that screen(ing) machine in use do not reveal by material, and framework is indeformable, and beam ring is firm.
Description
Technical field
The utility model is related to a kind of sealing structure, is particularly well-suited to the sealing between spin vibration sieve screen frame.
Background technology
It is plane that sealing between existing spin vibration sieve screen frame uses screen frame flange, and sealing ring is U-shaped, this sealing structure
Contact area is small, and for a long time using the generation for having Lou powder, and beam ring and screen frame contact surface are small, it may appear that beam ring loosens, sieve
Frame flange hoop strength is not enough also easy to deformation.
The content of the invention
Task of the present utility model is to propose that one kind is easy to use, and framework is indeformable, and ensures that screen(ing) machine is using process
A kind of spin vibration sieve screen frame and the sealing structure of rack that middle material is not revealed.
Task of the present utility model is done in such a way that it includes upper and lower screen frame, it is characterised in that：Upper screen frame and lower sieve
The edge of frame re-extends one bending sealing surface of composition along the whole circumference direction depression that stretches out, and the sealing ring is placed on
In bending sealing surface, the boss on sealing ring falls into the recess of bending sealing surface, and male-female engagement is surrounded and extruded, and beam ring beam exists
On screen frame with bending sealing surface, upper screen frame and lower screen frame are firmly squeezed on sealing ring.Upper screen frame and lower screen frame edge
Shape of cross section be in Ω shapes, rack be placed in the middle of upper and lower screen frame with sealing ring seal, it is described bending sealing surface be a circle
Ring muscle.
The utility model has the following effects that：The technical program simple structure, it is easy to use, it is ensured that screen(ing) machine is using process
Middle material is not revealed, and framework is indeformable, and beam ring is firm.
Brief description of the drawings
Fig. 1 is structure cut-away view of the present utility model.
Drawing explanation：1st, upper screen frame, 2, rack, 3, lower screen frame, 4, sealing ring, 5, beam ring, 6, bending sealing surface.
Specific embodiment
The edge of the upper screen frame 1 of the technical program and lower screen frame 3 is re-extended along the whole circumference direction depression that stretches out
A bending sealing surface 6 is constituted, furtherly, the shape of cross section at upper screen frame and lower screen frame edge is in Ω shapes, and rack 2 is placed on
The centre sealing ring 4 of upper and lower screen frame 3 is sealed, and the sealing ring 4 is placed in bending sealing surface 6, and the boss on sealing ring falls into
Bend the recess of sealing surface, male-female engagement surrounds and extrude, the beam of beam ring 5 on the screen frame with bending sealing surface, upper screen frame
Firmly it is squeezed on sealing ring with lower screen frame, this upper and lower screen frame with bending sealing surface can well ensure that screen(ing) machine exists
Material is not revealed during use, and framework is indeformable, and firmly, the bending sealing surface 6 is a ring muscle for circle to beam ring, so that
Improve the intensity of screen frame.So as to improve the radial strength of upper screen frame 1 and lower screen frame 3.
During installation, the stopper of sealing ring 4 is uniformly extruded on the circumference of screen(ing) machine rack 2, then stopper is had the net of sealing ring 4
Frame 2 is lain in a horizontal plane on lower screen frame 3, and the boss on sealing ring 4 is fallen into the recess of bending sealing surface 6, then again will be upper
Screen frame 1 is placed horizontally on the rack 2 of sealing ring 4, and the boss on sealing ring 4 falls into the recess of the bending sealing surface of screen frame,
With the beam of beam ring 5 on bending sealing surface, upper screen frame 1 and lower screen frame 3 are firmly squeezed on sealing ring 4, so as to effectively protect
Material is not revealed in use to have demonstrate,proved screen(ing) machine.
