The specific embodiment
Referring to accompanying drawing 1-5, the present invention wants disclosed this vibratory sieve to be applicable to the screening operation of broken rear calcium carbide under 400 celsius temperature states.Due to the movement locus sub-circular of this vibratory sieve, therefore be called circular motion shaking screen by those skilled in the art.
The vibrator 10 that this circular motion shaking screen comprises the screen box 1 of rectangular box structure, links together with screen box 1, is also useful on the bracing or strutting arrangement of support screen case.
For supporting the support plate of vibrator, by connectors such as high-strength connecting bolts, be fixedly connected with the side plate of screen box, vibrator is positioned at the top of screen box, because screen box is closed box, screen box and vibrator are worked respectively in two working spaces of keeping apart, and seal cover is and the position of screen box center of top near vibrator.Because the two is in two separate space, make high-temperature material and vibrator in screen box keep isolation, alleviate the impact of heat conduction on the connections such as vibrator inner bearing, rotation accessory, the wearing and tearing of material to vibrator jackshaft while simultaneously avoiding sieving, the preferred Hooks coupling universal coupling of jackshaft, has the advantages such as transmitting torque is large, aligning performance is good.Vibrator is connected with the shaft extension end that is positioned at the motor 12 of screen box side by yielding coupling 11, and motor is by 13 sides that are contained in screen box of motor cabinet, for vibrator is supplied with power.Be generally and avoid producing additional moment, guarantee screen box translation, vibrator axis is by the center of gravity of vibrating body.
Bracing or strutting arrangement comprises upper and lower two-stage shock mitigation system.Higher level's shock mitigation system comprises upper bracket 5 and the undersetting 7 being connected with screen box bottom, and one-level damping spring 6 is housed between upper and lower bearing.Subordinate's shock mitigation system comprises the base 8 being connected with undersetting 7, is provided with secondary damping spring 9 between base 8 and ground.Damping spring in shock mitigation system all adopts metal spring.Shock mitigation system is separately positioned on two ends and the both sides of screen box, and the height of undersetting mates with the angle of inclination of screen box integral body.The design of secondary vibration insulating system, has reduced the dynamic loading of screen(ing) machine to foundation ground, has reduced the investment on building foundation, and screen(ing) machine is when starting by resonance region, resonance amplitude reduces relatively, makes screen(ing) machine enter stably duty, when operation band material screen(ing) machine stability and safety more.
Owing to being provided with seal cover on screen box, calcium carbide material will carry out pan feeding, screening, discharging in totally enclosed space, also be provided with special dedusting mouth, for reclaiming dust simultaneously, reduce dust and the impact of gas on working environment, improved workman's working environment.
With this vibratory sieve, carry out the screening process of broken loose material, can regard as and be formed by two stages: the one, be less than the material bed arrival compass screen surface that the fine grained of screen size consists of coarse granule, be called for short and wear layer or layering; The 2nd, fine grained sees through sieve aperture becomes screenings, is called for short sieve thoroughly, and coarse granule is also discharged compass screen surface simultaneously becomes oversize.Therefore make coarse grain layer often in loose condition (of surface), be convenient to fine grained through the space between coarse granule, impel fine grained thoroughly to sieve.
