Abstract
A hydraulic high-frequency vibration sieve is designed for solving the problems that at present, a common sieving machine is low in sieving efficiency and production capacity when sieving fine materials. A vibration source acts on a vibrating beam directly; the vibrating beam causes a sieve mesh to vibrate through bearing; a sieve box does not vibrate; and the vibration sieve adopts high frequency and low amplitude to meet the sieving requirement of a large sieving inclination angle on the fine material. Sieve meshes of the high-frequency vibration sieve are independent vibration units, and can have different power, frequency and amplitude according to the material characteristic and the condition difference to improve the sieving efficiency and the production capacity. Meanwhile, compared with a common sieving machine, the hydraulic high-frequency vibration sieve is high in throughput, and low in noise and power consumption.
Description
Affiliated technical field
The utility model relates to the dither screening plant in a kind of vibration screening machinery, the dry screening of particularly suitable artificial sand making or the dry screening of other thin materials.
Background technology
Vibratory sieve is indispensable material grading apparatus in all industries such as metallurgy, coal, mine.At present, often process thin material with existing straight line shaker on the market, but because the straight line screen cloth is to vibrate with screen box, it is large to join the weight of shaking, frequency is restricted, and material is deposited in together at the first paragraph compass screen surface, soon layering with separate, there is limitation in screening: the one, to sieve not thoroughly, and screening efficiency is low; The 2nd, production capacity does not reach; The 3rd, easy stoppage phenomenon.
Summary of the invention
When processing thin material in order to overcome existing straight line shaker, the deficiency of screening efficiency and production capacity, Screening theory according to material: adopt large amplitude and small frequency (RPM) can obtain best screening effect for thick material, but for thin material, little amplitude and large frequency (RPM) then can obtain best screening effect, because fine particle just has the more close screen cloth of multimachine meeting like this, be sized out easily.The utility model provides a kind of high frequency shale shaker, and during this high frequency shale shaker work, screen box does not vibrate, only screen cloth vibration, and ginseng is shaken lightweight, and frequency is high, and material is layering and separation rapidly, promotes the saturating sieve of material.Simultaneously, can also be according to material characteristic and operating mode different, every screen cloth can have different power, frequency and amplitude, better improves screening efficiency and production capacity, satisfies instructions for use.
The utility model is in order to solve its technical problem, and by the following technical solutions: the fluid pressure type high frequency shale shaker is comprised of screen box, walking beam, spring members, screen cloth, hydraulic vibration pump, hydraulic power supply and frame.It is characterized in that: drive hydraulic vibration pump by hydraulic power supply and rotate, have maximum speed to reach 5000 rpms of eccentric blocks that also can produce exciting force in the oscillating column pump; On each root walking beam hydraulic vibration pump is installed, the oscillating column pump running drives walking beam; Walking beam connects with screen box by spring members, and spring members has been alleviated the impact of walking beam vibration on screen box, makes screen box not participate in vibration; The monolithic screen cloth is supported jointly by many walking beams, can be that two or three walking beams support screen cloth, forms an independently vibration unit, makes the screen cloth vibration by walking beam vibration screen cloth, and material is carried out a screening motion; Screen cloth can be one deck, two-layer or three layers in the screen box, and every layer also can be the polylith screen cloth.For different operating modes, the vibratory sieve inclination angle can be regulated.
The adjustment of fluid pressure type high-frequency screen vibratory sieve amplitude is to adjust by the angle that changes eccentric block in the oscillating column pump, and angle is larger, to produce amplitude larger.The adjusting of vibration frequency is to realize that by regulator solution press pump flow flow is larger, and rotating speed is higher, and vibration frequency is also just higher.According to layering and the relation of separating, then must increase the inclination angle of screening machine in order to increase screening efficiency.Increasing screening efficiency rule is: the angle of thick material screening is less than thin material; The screening angle of dry material is less than moist material.
The beneficial effects of the utility model are to adopt high-frequency, short arc, the satisfied needs of doing thin material screening.Every screen cloth is separate vibration unit, and is different with operating mode according to material characteristic, and every screen cloth can have different power, frequency and amplitude, to improve screening efficiency and production capacity.Simultaneously, screen box does not participate in vibration, has reduced and has joined the weight of shaking, and compares with the common sieve of same model, and treating capacity is large, motor power consumption is low, noise is low, economical and energy saving, and simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is fundamental diagram of the present utility model.

The specific embodiment
In schematic diagram shown in Figure 1, hydraulic vibration pump (5) drives walking beam (4) and does simple harmonic oscillation, thereby material (1) is pushed into left end (discharge end) from right-hand member (feeding end), meanwhile material is carried out screening operation, thin material leaks down from sieve screen apertures.Arrow is hydraulic vibration pump rotatory force direction.(2) are screen cloth among the figure, and (3) are spring members.
In the embodiment shown in Figure 2, (6) are tripper, and (7) are frame, and (8) are screen box, and (5) are hydraulic vibration pump, and (9) are oil pipe, and (10) are hydraulic power supply.
In the embodiment shown in fig. 3, screen cloth (2) drag hook one end connects with built-in beam (11), screen cloth (2) the drag hook other end connects with trave lling girder (12), middle by 2 or 3 walking beams (4) support, fixing trave lling girder after the screen cloth tensioning, locked screen cloth (2).
In the embodiment shown in fig. 4, spring members (14) one ends and sieve box side plate (13) bolt-connection, an end and walking beam (4) bolt-connection, during vibratory sieve work, but the slowing down vibration beam vibration is realized the screen cloth vibration to the impact of screen box, and screen box does not participate in vibration.
