Abstract

The utility model relates to a monospar vibration sieve, which is suitably used in sieving work of building material, metallurgy, power generation and coal mine. Two sides of straining box are respectively provided with a synchronous vibrator, and the two vibrators are respectively fixed on the same vibrating beam threading through bottom of the straining box. The inner side of bottom of the straining box penetrated by the vibrating beam is provided with a plurality of screen plates, and both ends of the vibrating beam are aslant arranged on a frame of the vibrating beam with buffering spring. By adopting rigid structure for the vibrators of the screen plate, sieve surface vibrates averagely and vibration of the straining box is prevented. Compared with prior art, the utility model has simpler structure, lesser weight, shouter period in design and production, fewer faults, higher production efficiency and wider practicality.

Description

A kind of single-beam exciting sieve

One, technical field

The utility model relates to sieving machine, a kind of specifically single-beam exciting sieve.

Two, background technology

Existing vibratory sieve mostly is screen cloth and screen box, and next plays vibration in the exciting force effect, complex structure, and the fault height has brought very big inconvenience to production, and screen box and Guan Liang are broken into the major failure that present vibratory sieve lost efficacy.Number of patent application " 97249115.5 " discloses a kind of electric and magnetic oscillation high frequency shale shaker, pass through transmission system, power transmission and shaker arm directly make the screen cloth vibration, and screen box is motionless or microvibration arranged, though changed the structure of this screen box screen cloth rigidity one, can avoid the fracture of screen box and Guan Liang, but because it adopts magnetic vibration to knock screen cloth by drive link and shaker arm, make exciting force little, knocking of screen cloth is limited in scope, make the vibration of screen cloth inhomogeneous, cause its efficient low, output is little, is only applicable to the dehydration of fine fraction screening and coal slime, and a kind of of vibratory sieve that can only become present widely used screen cloth screen box integrative-structure replenishes.

Three, technology contents

1. goal of the invention

In view of the deficiency that prior art exists, the purpose of this utility model provides a kind of simple in structure, and vibration is even, the single-beam exciting sieve that production efficiency is high.

2. technical scheme

A kind of single-beam exciting of the utility model sieve, it comprises motor, the screen box and the fixing support of screen box, the both sides of screen box are respectively equipped with the self-synchronization exciting device, and the both sides vibrator is separately fixed on the exciting beam that passes the screen box bottom; The inboard that the exciting beam passes the screen box bottom baffle is provided with the polylith sieve plate, and the inclination angle of parallel while with sieve plate of screen box with horizontal level is α, and exciting beam two ends are located at respectively on the exciting boom support that isolation spring is housed, and vibrator links by shaft coupling and motor.

A kind of single-beam exciting sieve of the utility model, the two ends of exciting beam form two groups of inertia vibration generators of self-synchronization exciting by bolting, by the isolation spring that is provided with under the exciting boom support, to alleviate impact to the basis, motor is located on the electric machine support, so that transferring power, screen box biside plate bottom is provided with rubber, the rubber base connects with sieve plate, and the polylith sieve plate is by being bolted on the exciting beam.The inclined angle alpha of screen box and sieve plate is 0～35 degree.

3. technique effect

A kind of single-beam exciting of the utility model sieves, and is best suited for the screening operation in building materials, metallurgy, electric power and colliery.Both sides at screen box are provided with the self-synchronization exciting device respectively, and the both sides vibrator is separately fixed on the same exciting beam that passes the screen box bottom; The inboard that the exciting beam passes the screen box bottom baffle is provided with the polylith sieve plate, and exciting beam two ends are located at respectively on the tilting exciting boom support that isolation spring is housed, owing to adopt the rigid structure of sieve plate vibrator, makes the compass screen surface vibration evenly.Compared with prior art, structure is simplified greatly, and weight alleviates greatly, and design and production cycle shorten greatly, and fault is few, and the production efficiency height has practicality widely.

Five, the specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

A kind of single-beam exciting of the utility model sieve, it is mainly by screen box 1, sieve plate 2, exciting beam 3, vibrator 4, motor 5, screen box support 6, exciting boom support 7, electric machine support 8, shaft coupling 9, isolation spring 10 is formed.The both sides of screen box 1 are respectively equipped with self-synchronization exciting device 4, and both sides vibrator 4 is separately fixed on the exciting beam 3 that passes screen box 1 bottom; The two ends of exciting beam 3 form two groups of inertia vibration generators 4 of self-synchronization exciting by bolting, the exciting boom support has isolation spring 10 7 times, to alleviate impact to the basis, vibrator logical 4 links by shaft coupling 9 and motor 5, motor 5 is located on the electric machine support 8, so that transfer motion power, be provided with 3 sieve plates 2 on the exciting beam 3 side by side, sieve plate 2 and exciting beam rigid attachment, balata belt is equipped with in screen box 1 biside plate bottom, balata belt base and 2 soft connections of sieve plate, the side plate of screen box can be participated in vibration, also can not participate in vibration.By screen box support 6 screen box 1 is held in the palm from the basis, frame stops the oversize material to flow out from the sieve plate both sides to sieve plate 2 both sides and perpendicular to sieve plate 2.Sieve plate 2 is 30 degree with the angle [alpha] on the basis of level, is convenient to material and glides, and angle [alpha] realizes by the height of the front and back pad of adjustment exciting boom support 7.

According to the motor synchronizing principle of inertia, the vibrator that the two ends inertia vibration generator produces is cancelled out each other along exciting beam direction, thereby only perpendicular to the power of the direction of exciting beam and sieve plate, this power passes to thing and basis, impulsive force to the basis reduces its impact by isolation spring, when the sieve plate at certain angle of inclination, material edge passed through, sieve plate just can play the sieving actoion to material like this.
