Abstract
The utility model relates to a spring vibration sieve, which comprises a sieve plate which is composed of a sieve frame and isolation fences, wherein, a spiral spring is arranged between each two adjacent isolation fences; the two ends of the spiral spring are respectively combined with the sieve frame. Because the utility model adopts the structure characteristics, the vibration intensity of the sieve surface is enlarged, the processes of loosening, layer division, sieve penetration of the material on the sieve surface are speeded up when a sieve box drives the sieve plate to vibrate because of the characteristics of self damping vibration of the spring, and a high-frequency small oscillation amplitude is compounded, and furthermore, wet and sticky material can not form paste clogging because the sieve surface has the self-excitation vibration ability, and thereby, the sieving efficiency of the unit area of the sieve surface and the service life can be increased.
Description
Technical field:
The utility model relates to a kind of spring vibration sieve, relates to a kind of spring vibration sieve that is used for material screening specifically.
Background technology:
Present known spring vibration sieve is mainly the string vibratory sieve, and its compass screen surface is made up of finer wire, and this structural vibrations sieve in use has the following disadvantages: one owing to the amplitude of finer wire is less, makes that the compass screen surface self-purification ability is relatively poor and easily stops up sieve aperture; Its two, finer wire frangibility and service life of reducing vibratory sieve.
The utility model content:
The purpose of this utility model provides a kind of spring vibration sieve with regard to being at above-mentioned existing in prior technology deficiency.
The purpose of this utility model can realize by following technical measures:
The utility model comprises the sieve plate of being made up of screen frame and barrier, is provided with helical spring between adjacent two barriers, and described helical spring two ends combine with screen frame respectively.
Advantage of the present utility model just is by be provided with helical spring between adjacent two barriers, make when screen box drives the sieve plate vibration, because the damping vibration characteristics of spring self, the small amplitude motion of a compound again last high frequency, so not only increased the oscillation intensity of compass screen surface, fully activated each material by compass screen surface, quickened material loose on compass screen surface, layering and saturating sieve process, and because the self-excited vibration ability that compass screen surface has, wet adhesive material also can't form sticks with paste plug, thus the screening efficiency and the service life of having improved the compass screen surface unit are widely.
Description of drawings:
Fig. 1 is a front view of the present utility model.
The specific embodiment:
The utility model describes in further detail below in conjunction with specific embodiment (accompanying drawing):
As shown in the figure, the utility model comprises the sieve plate of being made up of screen frame 1 and barrier 2, is provided with helical spring 3 between adjacent two barriers 2, and the two ends of described helical spring 3 combine with screen frame 1 respectively.
