Description

Connecting and fixing device suitable for vibrating type sieve bend

Technical Field

The utility model relates to a connect fixing device, concretely relates to connect fixing device suitable for vibration type sieve bend screen cloth.

Background

The vibrating type sieve bend is mainly used for the dehydration, desliming and medium removal operation of wet-process coal preparation in a coal preparation plant, the vibrating type sieve bend is in a working state, the bottom surface of a sieve box forms an inclination angle of 40-60 degrees with the horizontal plane, slurry is fed to the sieve bend along the tangential direction at a certain speed, under the action of centrifugal force, a slurry layer flows close to the sieve bend, in the process that the slurry layer flows from one sieve bar to the other sieve bar in the transverse arrangement, the edge of each sieve bar has a cutting effect on the slurry layer, meanwhile, a vibrating motor is installed on the sieve machine, the dehydration, desliming and medium removal effects are improved through vibration, the material discharge is accelerated, and the effective treatment area of the sieve mesh is ensured.

Currently, most vibrating trommel screens range in width from 1.2m to 4.2 m. When the sieve machine width surpassed 2m and the sieve machine was the single channel structure, the screen cloth leads to the screen cloth rigidity is lower owing to the restriction of screen seam and grizzly strip back of the body width, takes place the shake during the vibration easily to produce resonance with the sieve machine, phenomenon such as the screen cloth damage, reel fracture are damaged in big noise, amplitude when leading to the sieve machine during operation.

Disclosure of Invention

In view of this, the embodiment of the present invention provides a connection fixing device suitable for a vibration type sieve bend to solve the above technical problem.

In order to achieve the technical purpose, the embodiment of the utility model provides a connecting and fixing device suitable for a vibrating arc screen, which is improved in that the connecting and fixing device comprises a supporting seat, a clamping seat, an inner hexagonal socket head cap screw, a nut and a clamping groove;

the supporting seat top surface sets up the convex the cassette, the supporting seat with all set up mounting hole on the cassette, wear to establish in the mounting hole interior hexagonal socket head cap screw, just interior hexagonal socket head cap screw lower extreme extends to the supporting seat bottom surface is connected the nut, the extrusion of cassette tip is embedded into the shape of falling the concavity in the draw-in groove, two gaps that form between cassette both sides top surface and the draw-in groove both sides bottom surface are used for pressing from both sides the tip of establishing two screen meshes.

The utility model discloses owing to take above technical scheme, compare with prior art, it has following advantage:

the utility model discloses a set up the gap installation screen cloth between cassette and draw-in groove, the screen cloth is compressed tightly fixedly by cassette and draw-in groove to make the screen cloth can divide the body preparation, reduce the monolithic screen cloth size, improve monolithic screen cloth rigidity, reduce the screen cloth vibration range, thereby reach the purpose of avoiding resonance, improving screen cloth life.

The utility model has the advantages of scientific and reasonable design, simple structure, it is convenient to dismantle, and is with low costs, and wear resistance is good, and longe-lived, can wide application in the fixed process of connection of various sieve arcs.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

As shown in fig. 1-2, an embodiment of the present invention provides a connecting and fixing device for a vibrating sieve bend, which includes a supporting seat 1, a clamping seat 2, an inner hexagonal socket head cap screw 3, a nut 4 and a clamping groove 5;

1 top surface of supporting seat sets up convex cassette 2, all set up the mounting hole on supporting seat 1 and the cassette 2, wear to establish hexagon socket head cap screw 3 in the mounting hole, and 3 lower extremes of hexagon socket head cap screw extend to 1 bottom surface of supporting seat and coupling nut 4, in order to realize the dismantled fixed connection of supporting seat 1 and

cassette

2, 2 tip extrusion of cassette are embedded in the inverted concave shape draw-in groove 5, two gaps that form between 2 both sides top surface of cassette and the 5 both sides bottom surfaces of draw-in groove are used for pressing from both sides the tip of establishing two screen cloth 6, in order to press from both sides two screen cloth 6 of tight fixed connection through the extrusion, and then realize the components of a whole that can function independently fixed connection of screen cloth 6.

Obviously, above scheme is unpowered structure, and the gap between cassette 2 and draw-in groove 5 is used for installing screen cloth 6, and screen cloth 6 is compressed tightly fixedly by cassette 2 and draw-in groove 5 to make screen cloth 6 can the components of a whole that can function independently preparation, reduce monolithic screen cloth size, improve monolithic screen cloth 6 rigidity, reduce screen cloth 6 vibration amplitude, thereby reach the purpose of avoiding resonance, improving screen cloth 6 life.

Meanwhile, the clamping seat 2 and the clamping groove 5 can be disassembled and assembled for multiple times, and the clamping seat is simple in structure and convenient to disassemble and assemble.

In one embodiment, a washer 7 is provided between the bottom surface of the support base 1 and the nut 4 to prevent the bottom surface of the support base 1 from being scratched by the nut 4.

In one embodiment, the supporting seat 1 may be an angle steel, and the side surface of the angle steel is detachably and fixedly connected with the screen frame 8, so as to further improve the stability of the screen 6.

In one embodiment, the angle steel is a curved angle steel, and the curved wrap angle is the same as the wrap angle of the trommel screen 6.

In one embodiment, the clamping seat 2 and the clamping groove 5 are made of polyurethane, so as to further prolong the service life of the screen.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and it will be apparent to those skilled in the art that various modifications and variations can be made in the embodiments of the present invention.
