The invention belongs to the vibration screening machinery field, mainly relating to material particles is elliptical trajectory on compass screen surface, can sieve the elliptical orbit vibratory sieve of critical particle hole clipping problem in difficult screened material or the solution material.
Background technology
In existing linear vibrating screen and circular shale shaker, the linear vibrating screen vibrating deflection is single, critical particle easily forms hole clipping in the material on screen cloth, though non-hole clipping of circular shale shaker material, but under equal performance parameters condition, the conveying capacity of material is poor, has only the elliptical orbit vibratory sieve just to possess material not plug-hole and the strong advantage of conveying capacity simultaneously.Existing three shaft elliptic vibrative screen, elliptical orbit are that three axles force Synchronous Transmission to realize by gear, its complex structure, and the manufacturing cost height, amplitude is adjusted inconvenient, and operating fault rate is also than higher.
Summary of the invention
The purpose of this invention is to provide a kind of elliptical orbit vibratory sieve, this vibratory sieve has solved the screening of difficult screened material and the problem of material hole clipping preferably, has improved the screening efficiency of vibratory sieve.
The present invention is achieved by the following measures, mainly screen box, vibrator, vibration damping support device and the transmission gear for electric motor that is made of screen frame and compass screen surface formed, it is characterized in that: described elliptical orbit vibratory sieve is the vibrator that two kinds of structures are installed on screen frame, is respectively that the twin shaft gear forces synchronous exciter device and one-eccentric rotor type vibrator.The twin shaft gear force the synchronous exciter device be installed in driving girder on the screen frame above, it is 1 gears engaged counter-rotation that its two axles such as pass through at parameter, gearratio, transmission gear for electric motor is connected with axle wherein, produce the barycenter of the force action line of exciting by the vibratory sieve screen box, make screen box form the straight-line oscillation track in fore-and-aft plane, the adjusting range of vibrating direction angle is 30～60 °.One-eccentric rotor type vibrator be installed on two side plates of screen frame or drive girder below, axis is vertical with the side plate of screen frame, its center is arranged on the force action line that the twin shaft gear forces the synchronous exciter device, is driven by transmission gear for electric motor, makes screen box form the circular vibration track in fore-and-aft plane.The twin shaft gear forces that the vibration of synchronous exciter device and one-eccentric rotor type vibrator is synthetic to make screen box produce the elliptical vibration track in fore-and-aft plane.
According to the specification of vibratory sieve and the needs of screening material, the shape of elliptical vibration track is that the twin shaft gear forces the eccentric mass of eccentric block on synchronous exciter device and the one-eccentric rotor type vibrator to adjust, and can change the size of elliptical vibration track major axis and minor axis thus.The major axis of elliptical vibration track forces eccentric mass adjustment on the synchronous exciter device by the twin shaft gear; The minor axis of elliptical vibration track is by the eccentric mass adjustment on the one-eccentric rotor type vibrator.It is a plurality of that the twin shaft gear forces the synchronous exciter device can connect on the vibrator mounting rail to be provided with.One-eccentric rotor type vibrator can be replaced by vibrating motor, be installed in screen frame the driving girder below.Compass screen surface is 1～3 layer, and the inclination angle of compass screen surface is 0～30 °, and the shape of compass screen surface is linear or broken line shape.
The invention has the beneficial effects as follows, force synchronous exciter device and two vibrators of one-eccentric rotor type vibrator to work simultaneously owing to use the twin shaft gear, so the operation of the elliptical vibration track of screen box is accurate, stable, the bed of material is even, possesses the strong advantage of material non-blocking screen hole and conveying capacity simultaneously.And can determine the shape of screen box elliptic vibration track according to the concrete condition of screening material.Have compact conformation, operate steadily, characteristics such as easy to adjust and screening efficiency height, be applicable to the screening of every profession and trade difficult screened material.
