Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art part, a kind of heavy multistage screening plant is provided, this equipment has a plurality of screen boxs by identical inclination angle permutation and combination, the screen box inclination angle is 15-30 °, each screen box is independently controlled, independent vibration, reduce screening plant to the impact of base surface by the secondary vibration damping, screen box satisfies the vibrating machine requirement by big oscillation intensity, large amplitude, high inclination-angle and elastic screen surface and to the screening characteristics of various materials, in the screening process characteristics of motion, compass screen surface linearly moves, and obtains good screening treatment effect.Equipment as safety guard, prevents the material dust from flying by the side plate on the screen box, reduces the pollution to air, keeps good working environment, thereby reaches environmental requirement.Vibrator adopts high-strength bolt to be connected with side plate, is convenient to dismounting, greatly reduces the workload of repair and maintenance.Frame one side has motor cabinet, and the motor cabinet position can be put mutually according to the relative frame left and right sides of field condition, more flexibly the reasonable use site space.
The utility model is achieved by the following technical solution: a kind of heavy multistage screening plant, this equipment includes frame, it is characterized in that: by identical inclination angle permutation and combination a plurality of screen boxs are arranged on the described frame, the screen box inclination angle is 15-30 °, screen box is seated in above the frame by main vibration spring, and the secondary shock-absorbing spring is arranged between frame and the ground; Described frame one side has motor cabinet, and motor is fixedly arranged on the motor cabinet; Each screen box connects two groups and is flexible coupling, and motor is by the outputting power that is flexible coupling.
Described screen box two ends have side plate respectively, and secured in parallel has two groups of rectangular beams between the biside plate, has fastened the sieve plate support by U-shaped on the rectangular beam, by pressing plate sieve plate is arranged fixedly on the sieve plate support, and rebound is also fixedly arranged on the sieve plate support; Also by bolting the main vibration spring seat is arranged on the described rectangular beam, every group of vibrator is fixed by bolts on the side plate after passing rectangular beam respectively, and stiffener is also fixedly arranged on the side plate.
Be arranged with some silk screens on described each sieve plate, the silk screen orientation is parallel or perpendicular to flow direction of material, silk screen is fixed on the silk screen frame.
Described vibrator is connected with motor by being flexible coupling.
The utility model has the advantages that: this screening plant passes through by a plurality of screen boxs of identical inclination angle permutation and combination, and each screen box is independently controlled, and independent vibration has realized the maximization of equipment, and high throughput has improved screening efficiency.Main shaking by motor by the drive vibrator that is flexible coupling carried out the vibration of need of work thereby drive screen box.15 °-30 ° of screen box inclination angle scopes, each screen box has two groups of vibrators, two groups of synchronous incorgruous rotations of vibrator during work, screen box is linearly moved, thereby improve oscillation intensity and the amplitude of each screen box, satisfy the vibrating machine requirement and to the screening characteristics of various materials, in the screening process characteristics of motion, obtain good screening treatment effect by big oscillation intensity, large amplitude, high inclination-angle and elastic screen surface; The secondary vibration damping makes complete machine in the course of the work, and the dynamic loading of carrying the basis is reduced, and has also reduced the sound that mechanical impact produces simultaneously, thereby has reduced noise, satisfies environmental requirement; Frame one side has motor cabinet, and the motor cabinet position can be put mutually according to the relative frame left and right sides of field condition, more flexibly the reasonable use site space.
