Description
Technical field
The present invention relates to a kind of asphalt mixing station equipment, specifically a kind of bituminous mixing plant elliptically vibrating screen.
Background technology
Current bituminous mixing plant vibratory sieve used is divided into linear vibrating screen and circular shale shaker two kinds by movement locus.The feature of linear vibrating screen is that conveying capacity is large, and device height is low, but the movement locus of its orthoscopic makes material effectively layering not sieve.And the material close with mesh size is stuck on screen cloth and is difficult to dish out with the vibration of screen(ing) machine, produce plug-hole phenomenon, clear net can reduce the screening efficiency of vibratory sieve not in time greatly.For the circular shale shaker of circus movement track, when sieve nest vibrates, material can be good at layering, and is not easily stuck in sieve aperture, there is higher screening efficiency, but its shortcoming to be inclination angle large, equipment is high, conveying capacity is little, in bituminous mixing plant, can only do miniaturized use.
The elliptically vibrating screen of existing other field, its vibrating motor is normally arranged on sieve nest side plate, and the vibratory sieve on asphalt mixing plant, need to arrange corresponding heat-preserving equipment in sieve nest, therefore, the elliptically vibrating screen of existing other field can not be applied in mixing station.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides one and be applicable to bituminous mixing plant elliptically vibrating screen, movement locus is oval, integrates linear vibrating screen and circular shale shaker advantage.
To achieve these goals, a kind of bituminous mixing plant elliptically vibrating screen of the present invention, involving vibrations sieve nest, gripper shoe, motor base crossbeam, vibrating motor, screen cloth and take-up device; Multiple intermediate supports beam is furnished with from top to bottom in the plate of described vibratory sieve side; Screen cloth one end of described vibratory sieve is connected on intermediate supports beam, and the other end connects on screen tension device; Described vibration sieve nest top is provided with the two piece gripper shoes consistent with side plate inner width, is connected with the motor base crossbeam of rectangular beam structures between two pieces of gripper shoes; Described vibrating motor is provided with two, and its rotating speed is identical, and exciting force is different, and two vibrating motor symmetries are fixed on motor base crossbeam; When vibratory sieve runs, the direction of rotation of two vibrating motors is contrary.
As further scheme of the present invention, the multiple brace summer of described intermediate supports beam arranged on both sides; Screen cloth is fixed on curved structure on brace summer.First brace summer is arranged in a certain way, screen cloth is being fixed on brace summer, make screen cloth face form the structure of arc, on the screen cloth face of arc, sieve nest oscillatory type, can realize the rolling of material, make thickness material switch, be more conducive to the layering of material.
As a kind of scheme of the present invention, described motor base crossbeam is provided with installing hole, and two vibrating motors are with high strength studs, and two ends double nut is fixed on motor base crossbeam.
As further scheme of the present invention, between described high strength studs and double nut, be coated with screw thread glue.During due to vibratory sieve operation, the vibration of generation, easily make stud and nut produce and loosen and depart from, traditional mechanical lock solid method is all not ideal enough, scribbles screw thread glue here at stud and nut piece, can effectively lock locking.
As further scheme of the present invention, described screen tension device includes spring.The reposition element that other are applicable to can certainly be selected.
As further scheme of the present invention, in described vibration sieve nest, be provided with multilayer screen cloth from top to bottom.Here can have more the number of plies needing to arrange screen cloth, multilayer screen cloth can realize the finer screening of material.
The present invention increases motor mount crossbeam at vibratory sieve top, by identical for two rotating speeds, the different vibrating motor of exciting force is fixed on motor base crossbeam, when vibratory sieve runs, the direction of rotation of two vibrating motors is contrary, theoretical according to not waiting mass-radius product Double shaft self synchronous, vibratory sieve can produce stable elliptic motion trace.Vibrating motor is reasonably arranged on outside sieve nest by the present invention, the architecture basics adapting to mixing station achieves elliptical vibration track, this elliptically vibrating screen integrates linear vibrating screen and circular shale shaker, there is disposal ability large, device height is low, rational in infrastructure, the easy layering of material, not easily plug-hole, screening efficiency advantages of higher.

Detailed description of the invention
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, bituminous mixing plant elliptically vibrating screen of the present invention, involving vibrations sieve nest 1, gripper shoe 2, motor base crossbeam 4, vibrating motor 5, screen cloth 6 and take-up device 7; Multiple intermediate supports beam 9 is furnished with from top to bottom in vibration sieve nest 1 side plate 3; Screen cloth 6 one end of vibratory sieve is connected on intermediate supports beam 9, and the other end connects on screen tension device 7; Vibration sieve nest 1 top is provided with the motor base crossbeam 4 being connected with rectangular beam structures between two pieces of gripper shoes consistent with side plate 3 inner width, 2, two pieces of gripper shoes 2; Vibrating motor 5 is provided with two, and its rotating speed is identical, and exciting force is different, and two vibrating motor 5 symmetries are fixed on motor base crossbeam 4, and when vibratory sieve runs, the direction of rotation of two vibrating motors 5 is contrary.Theoretical according to not waiting mass-radius product Double shaft self synchronous, by rationally arranging mass-radius product, the distance of shaft centers of vibrating motor, and installation site, the centre of force that its motor synchronizing is produced overlaps with sieve nest center of gravity, and namely vibratory sieve can produce stable elliptic motion trace.
The present invention increases motor mount crossbeam 4 at vibratory sieve top, by identical for two rotating speeds, the different vibrating motor 5 of exciting force is fixed on motor base crossbeam 4, when vibratory sieve runs, the direction of rotation of two vibrating motors 5 is contrary, theoretical according to not waiting mass-radius product Double shaft self synchronous, vibratory sieve can produce stable elliptic motion trace.
On said structure basis, the present invention is also at the multiple brace summer 8 of intermediate supports beam 9 arranged on both sides; Screen cloth 6 is fixed on curved structure on brace summer 8.During installation, first brace summer 8 is arranged in a certain way, screen cloth 6 is being fixed on brace summer 8, screen cloth face is made to form the structure of arc, on the screen cloth face of arc, sieve nest oscillatory type, the rolling of material can be realized, make thickness material switch, be more conducive to the layering of material.
As shown in Figures 2 and 3, the present invention provides the installation embodiment of a motor, and motor base crossbeam 4 is provided with installing hole, and two vibrating motors 5 are with high strength studs 10, and two ends double nut 11 is fixed on motor base crossbeam 4.And between high strength studs 10 and double nut 11, be coated with screw thread glue further.During due to vibratory sieve operation, the vibration of generation, easily make stud and nut produce and loosen and depart from, traditional mechanical lock solid method is all not ideal enough, scribbles screw thread glue here at stud and nut piece, can effectively lock locking.
