Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of slurry balance shield slurry dewatering vibrating screen, including left screen box plate 1, rear screen box plate 2, the right side
Screen box plate 4 and motor 10 are equipped with sieve plate between left screen box plate 1 and right screen box plate 4, sieve plate includes upper sieve plate 7 and lower sieve plate 8,
Upper sieve plate 7 and 8 top of lower sieve plate are equipped with uniform distributor 3, and motor 10 is connect with shaft 6 by Hooks coupling universal coupling 9, shaft 6
It is supported on left screen box plate 1 and right screen box plate 4, eccentric block 5 is equipped in shaft 6 and constitutes vibrator；Eccentric block 5 is two, position
In the outside of left screen box plate 1 and right screen box plate 4, motor 10 is connected on motor cabinet 11, and motor 10 is two groups, and shaft 6 is also corresponding
It is two groups；Two groups of vibrators are horizontally disposed, and two groups of vibrators are respectively positioned on position of the same side far from feed inlet of Vibration Screen；
4 screen(ing) machine pedestals 13 are distributed in the surrounding of vibrating screen, metal-rubber bullet 12, metal-rubber spring are connected on screen(ing) machine pedestal 13
12 form for wire 14 and rubber 15.
As shown in Fig. 2, slurry balance shield provided by the invention is in slurry dewatering vibrating screen, two groups of vibrators are at level
It places, according to Nonlinear Dynamical Principle, the direction of vibration of entire screen frame will be along the center of two groups of vibrators and body（Screen frame
Body+upper and lower sieve plate+material）The line direction of barycenter；As shown in phantom in Figure 2, in traditional slurry dewatering vibrating screen, two groups are swashed
The device line that shakes needs are vertical with direction of vibration, certainly will increase vibrating screen whole height in this way；In the present invention, due to vibrator level
It places, vibrating screen whole height can become smaller.
As shown in figure 3, placed since the vibrator that uses of the present invention turns inclined formula, upper sieve plate 7 and lower 8 centroid position of sieve plate
Material moving track is linear, and the Material moving track of upper sieve plate 7, the feed end of lower sieve plate 8 and discharge end is to be similar to directly
The long ellipse of line；In this way, the material speed of service in discharge end is slightly below the material speed of service at centroid position, so as to
Increase the compass screen surface residence time, improves screening efficiency.
As shown in figure 4, upper sieve plate 7 and 8 top of lower sieve plate are equipped with uniform distributor 3, mud first falls on uniform distributor 3
On, it is fallen on again on upper sieve plate 7 and lower sieve plate 8 by equally distributed aperture on uniform distributor 3, in this way, material can sieve
It is uniformly distributed on plate, improves screening efficiency；Traditional slurry balance shield in slurry dewatering vibrating screen do not have uniform distribution
Device, material are transported to compass screen surface by a pipe, cause only to accumulate in compass screen surface smaller range, can only be run with material gradual
It scatters, this process influences screening efficiency.
As shown in figure 5, slurry balance shield provided by the invention is metal with the isolation spring in slurry dewatering vibrating screen
Rubber spring 12 is made of wire 14 and rubber 15；Since there is isolation spring rubber 15, the noise of entire vibrating screen will subtract
It is small, moreover, because rubber 15 is with non-linear so that metal-rubber spring 12 is whole to have rigid nonlinear characteristic, that is, is becoming
Rigidity also becomes larger when deformation is big so that vibrating screen peak swing when passing through resonance region reduces, and principle is as shown in Figure 6.
Operation principle：When using the slurry dewatering vibrating screen, material（Mud）It falls on first on uniform distributor 3, so
It is fallen on sieve plate up and down by equally distributed aperture on uniform distributor 3 afterwards, in this way, material can equably pave in upper sieve
On plate 7 and lower sieve plate 8, screening efficiency is improved；Motor 10 rotates drive shaft 6 and rotates, due to Nonlinear Dynamics, shaft
5 adjustment phase place of eccentric block on 6, exciting force resultant direction are direction of vibration shown in Fig. 2；Upper sieve plate 7 and lower sieve plate 8 are swashing
Movement locus as shown in Figure 3 is generated under force effect of shaking, driving material is run to discharge end；Moisture on upper sieve plate 7 in material
It is fallen on lower sieve plate 8 by the aperture of sieve in upper sieve plate 7, grit and soil etc. are discharged from discharge end；Material on lower sieve plate 8
Moisture is discharged by the aperture of sieve in lower sieve plate 8, and grit and soil etc. are discharged from discharge end, in this way, realizing grit, soil
With the separation of moisture, here it is the operation principles of the slurry dewatering vibrating screen.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It still can be with technical scheme described in the above embodiments is modified, or is carried out to which part technical characteristic etc.
With replacing, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection domain of invention.
