Biomass material screening plant
The present invention relates to a kind of screening plants, specifically, relate to a kind of biomass material screening plant.
In the production process of biomass fuel, the degree of purity of raw material plays decisive role for the quality of finished product, and
Biomass fuel needs to prepare a large amount of raw material in production, these raw material usually outdoor placement two weeks even one
Month, it in the process, is easy to be mixed into the impurity such as stone, sand and dust, along with the purity of raw material itself is not high, causes to produce
Also it is mixed into a large amount of impurity in biomass fuel, final product quality is influenced serious.
In order to solve the above problems, people are seeking always a kind of ideal technical solution.
The purpose of the present invention is in view of the deficiencies of the prior art, to provide, a kind of design science, screening effect is good, improves
The biomass material screening plant of material purity.
To achieve the goals above, the technical solution adopted in the present invention is：A kind of biomass material screening plant, it is wrapped
The first screening machine for being connected to crusher feed-inlet is included, first screening machine includes vibrations screen box, is mounted on the reciprocating sieve
Netted tray in case, the funneling slideway below the netted tray and connect the appearance exported under the funneling slideway
Receive room, the reciprocating sieve case includes babinet, holder, the resilient support being connected between each corner of the babinet and holder, driving
The vertical shaking device that the babinet vertically shakes and the transverse vibration device for driving the babinet transverse vibration.
Described on base, the netted tray is tapered.
Described on base, the discharge port of the vibrations screen box is set to the side of the babinet, and the funneling slideway is under
Outlet bends towards the discharge port side of the vibrations screen box, and it is articulated structure, the shake that the vibrations screen box lower end, which corresponds to discharge port side,
Hydraulic mandril is installed to drive the vibrations screen box to topple over raw material in the other side of dynamic screen box lower end.
Described on base, the resilient support includes the support spring in each corner for being tiltedly mounted on the babinet.
Described on base, the transverse vibration device and the vertical shaking device are vibration motor, two vibration motors
Both ends are articulated and connected with the babinet and the holder respectively.
Described on base, it further includes the second screening machine for being connected to the discharge hole of crusher, and second screening machine is
The present invention has substantive distinguishing features outstanding and significant progress compared with the prior art, and specifically, the present invention exists
Before raw material does not enter crusher, increase by the first screening machine, raw material volume is larger at this time, and built-in rubble and little particle impurity are easy
It is eliminated, using the vertical tremor for shaking screen box and controls vibrations, these short grained rubbles and impurity from netted tray
It leaks out in mesh, is then sent from funneling slideway into accommodating chamber, periodically removed, the effect of resilient support is bradyseism and offer one
Fixed vibration displacement amount.
Further, netted tray is taper, and the larger object of volume is easier to be erected on the tray of taper,
Vibrating effect is more preferable.
Further, discharge port is set to side, and discharge method is rollover Dumpage type, and the lower outlet of funneling slideway at this time
Discharge port side is bent towards, impurity is not easy to be poured out from lower outlet when toppling over.
Further, it flexibly supports to be tiltedly mounted on the support spring in each corner, eight corners are oblique by spring
Fixed with external fixed frame, convenient for babinet transverse vibration and vertical vibrations, the vibrations in two directions are driven by vibration motor.
Further, the second screening machine includes the cyclone separator for connecting discharge hole of crusher, and material after crushing is interior
The dust in portion is also without removing, after being removed by the cyclone separator, remaining feed purity higher.
It has the advantages that design science, screening effect are good, improve material purity.

Specific implementation mode
Below by specific implementation mode, technical scheme of the present invention will be described in further detail.
As depicted in figs. 1 and 2, a kind of biomass material screening plant, it includes be connected to crusher feed-inlet first
Screening machine, first screening machine include shaking screen box, the netted tray 2 in the vibrations screen box, being set to the net
The funneling slideway 3 of 2 lower section of shape tray and the accommodating chamber 4 for connecting 3 times outlets of the funneling slideway, the reciprocating sieve case include
Babinet 1, the resilient support 6 being connected between 1 each corner of the babinet and holder 5, drives the babinet 1 vertically to shake at holder 5
Vertical shaking device 7 and the transverse vibration device 8 for driving 1 transverse vibration of babinet.The netted tray 2 is tapered.It is described
Shake screen box discharge port 9 be set to the babinet side, the funneling slideway 3 to lower outlet bend towards the vibrations screen box
Discharge port side, it is articulated structure that the vibrations screen box lower end, which corresponds to discharge port side, the other side peace of the vibrations screen box lower end
Hydraulic mandril 10 is filled to drive the vibrations screen box to topple over raw material.The resilient support 6 includes being tiltedly mounted on the babinet
Each corner support spring.The transverse vibration device 7 and the vertical shaking device 8 are vibration motor, vibration motor
Installation need certain activity, when ensureing that vibrations occur, motor can generate the offset of certain angle and position, with cooperation
The vibrations of babinet, specific practice can be hinged the tail end of motor or even two connecting pins of motor are hinged, can be with
Babinet is swung.It further includes the second screening machine for being connected to the discharge hole of crusher, and second screening machine is cyclonic separation
The course of work, raw material is sent into the first screening machine, and since volume of material is larger at this time, vibrations screen out the little particle included
Impurity and lithotrity effect are preferable, and therefore, using vibrations screen box screening, vertical vibration motor and transverse vibration motor drive the case
Body vertically vibrations and transverse vibration, under the action of support spring, babinet 1 can do similar circumference to vibrations, comprehensive shake
Kinetic energy is enough to remove the stone included to greatest extent, as the installation of motor, both may be mounted on babinet 1, and can also install
On holder 5, motor has certain offset, and installation site is that activity is unfixed, its purpose is to ensure circumference to
Vibrating effect more preferably, after vibrations separation a period of time, jacks up babinet by hydraulic strut, raw material is poured out, into crusher,
After crushing, the second screening machine is entered back into, the second screening machine further increases original for screening out the dust included, grey matter object etc.
The precision of material improves product quality to enter subsequent former.
Finally it should be noted that:The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
It can modify to the specific implementation mode of the present invention or equivalent replacement is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
