Abstract
The utility model discloses a self-balancing relaxation sifter for sifting loose middle fine particle materials with greater viscosity. The self-balancing relaxation sifter is composed of a machine frame, a vibration damping device, a transmission system, an inner sifting box, an outer sifting box, a sifting plate, a balance buffer device, etc. The inner sifting box and the outer sifting box are connected with each other through a support spring plate, and flexing sifting plates are respectively fixed on the cross beams of the inner and the outer sifting boxes. The balance buffer device is arranged between the inner and the outer sifting boxes. When the inner and the outer sifting boxes do reciprocating linear motions in opposite directions, the sifting plate does relaxation motion to throw up the materials toward the direction perpendicular to the sifter surface and make the materials move forward along the inclined sifter surface. In this way, the sifting of materials is realized. The utility model has the advantages of big throughput in unit area, high sifting efficiency, difficult sifter blocking, stable running, etc.
Description
The utility model belongs to the self-balancing flip flop screen that is used for sieving the thin grade particles material of the bigger diffusing shape of viscosity in the industrial and mining enterprises.
Flip flop screen is by the stretched and relaxed motion of flexible screen cloth material to be thrown perpendicular to compass screen surface, and compass screen surface tilts material is along inclined direction carried, thereby realizes screening.Its inside and outside screen box of existing flip flop screen links to each other with the chassis by support spring plate system respectively, and the chassis is connected with frame by the rubber spring vibration absorber again.And transmission system is arranged on the chassis, and a bidirectionally eccentric axle that is 180 ° of settings is arranged, and an eccentric shaft is connected with interior screen box, and another eccentric shaft is connected with outer screen box.When transmission system drove the eccentric shaft rotation, inside and outside screen box was promptly made rightabout linear reciprocating motion, had reached the purpose of screening material.Because the movement parts of this screen(ing) machine is more, complex structure, thereby weight is bigger, the power of consumption is big, and makes also relatively more difficult.
The purpose of this utility model is that design at the deficiencies in the prior art a kind of has characteristics such as the unit are treating capacity is big, screening efficiency is high, dynamic load is little, is applicable to the self-balancing flip flop screen of thin grade particles material in the bigger diffusing shape of screening viscosity.
The utility model mainly is made up of frame, vibration absorber, transmission system, rod spring plate system, interior screen box, outer screen box, sieve plate, equalizing and buffering spring and support spring plate system etc.This flip flop screen has inside and outside two screen boxs, and inside and outside screen box connects by support spring plate system, the upper surface of its inside and outside screen box sieve cross member at grade, inside and outside screen box crossbeam is crisscross arranged.Strip flexible polyurethane sieve plate is arranged on the crossbeam of screen box bottom surface successively, and the one side is fixed on the outer screen box crossbeam, and opposite side is fixed on the interior screen box crossbeam.When inside and outside screen box was made the opposite linear reciprocating motion of direction, sieve plate was promptly done relax a tension and relaxation motion of one.Interior screen box is placed on the frame of inclination by vibration absorber, and vibration absorber is made up of rubber spring and helical spring etc.Drive train arrangement is on interior screen box, and the eccentric diameter of axle of transmission system is connected with outer screen box by rod spring plate system.Be provided with balance and buffer device along reciprocating direction between the inside and outside screen box, this device both had been used for the partical gravity of balance screen box, and inside and outside screen box is operated steadily, and had improved the stress of each parts; This device is made up of helical spring, also can be made up of elastomeric elements such as leaf spring or rubber springs.When transmission system is moved under the drive of motor, outside reaching power by the rod spring plate, the eccentric shaft that rotates on interior screen box on the screen box, make inside and outside screen box make the opposite linear reciprocating motion of direction.Sieve plate is promptly made a tension and relaxation of relaxing and is moved under the drive of inside and outside screen box crossbeam, the vertical compass screen surface of material that will be positioned on the sieve plate face is thrown.Simultaneously, the compass screen surface of inclination travels forward material, thereby has realized the screening of material.
The utlity model has that the unit are treating capacity is big, screening efficiency is high, be difficult for plug-hole, fatigue life height, characteristics such as operate steadily, be specially adapted to sieve viscosity such as water-coal-slurry, slag or rubbish bigger in thin grade particles bulk material.
Accompanying drawing 1 is a structural representation of the present utility model, and (1) is interior screen box among the figure; (2) be outer screen box; (3) be support spring plate system; (4) be polyurethane sieve plate; (5) be interior screen box crossbeam; (6) be outer screen box crossbeam; (7) be rod spring plate system; (8) be transmission system; (9) be helical spring; (10) be motor; (11) be electric machine support; (12) be frame; (13) be rubber spring; (14) be balance and buffer device.
An existing accompanying drawings embodiment of the present utility model.Outer screen box (2) is suspended on the interior screen box (1) by support spring plate system (3), and the upper surface of the crossbeam (5) of interior screen box (1) and the crossbeam (6) of outer screen box (2) at grade.Interior screen box crossbeam (5) and outer screen box crossbeam (6) are crisscross arranged.On the screen box crossbeam (5), opposite side was fixed on the outer screen box crossbeam (6) in one side of strip polyurethane sieve plate (4) was fixed on.Be provided with balance and buffer device (14) along reciprocating direction between interior screen box (1) and the outer screen box (2), this device is made up of helical spring, is arranged on the both sides of inside and outside screen box lower end.Interior screen box (1) is placed on the frame (12) of inclination by vibration absorber.This vibration absorber is formed by rubber spring (13) with at the helical spring (9) of the upper end of interior screen box (1) and frame (12) dress.Transmission system (8) device is on interior screen box (1), and the eccentric diameter of axle of transmission system (8) is connected with outer screen box (2) by rod spring plate (7).When the eccentric shaft of the transmission system (8) on the interior screen box (1) rotates with certain revolution, by rod spring plate (7) power is reached on the outer screen box (2), make interior screen box (1) and outer screen box (2) drive the screen box crossbeam and make the opposite linear reciprocating motion of direction.Sieve plate (4) is promptly made a tension and relaxation of relaxing and is moved under the drive of inside and outside screen box crossbeam, the compass screen surface that material is thrown and the edge tilts that will be positioned on the compass screen surface travels forward, and has realized the screening of material.
