Description
Technical field
The invention belongs to machinery equipment field, and in particular to a kind of solid material grading screening machine.
Background technique
In the Workplace that coal, building stones sieve and other solid materials are crossed with sieve classification, drum-type screening machine is still more typical.
Existing drum-type screening machine sieve includes rack, the screen drum bracket being mounted on sieve seat, the sieve rack-mount by idler wheel
Cylinder, the driving gear engaged with driven gear ring, is fixed on sieve seat and installs sliding tooth the driven gear ring being fixed on screen drum circumferential surface
The motor of wheel or motor-driven speed reducer.Screening machine determines the slot size on screen drum during manufacturing, according to screening object, sieves
After hole is formed on screen drum, the sieve pore on screen drum is fixed, and is limited in screen size range on one point.It can only be to phase
It answers the material of granularity to be sieved, cannot achieve screening of the same equipment to material of different grain size, when needing to sieve different grain size
Material when.Screen drum or another standby corresponding screening machine can only be replaced.
Summary of the invention
The object of the present invention is to provide a kind of drum-type screening machines of changeable slot size, for solid particle material
Grading overcomes existing drum-type screening machine above shortcomings.
Screening machine of the invention includes: rack, is fixed on the rack screen drum support roller bearing, the sieve being mounted on support roller bearing
Cylinder, the screen drum transmission rolling shaft being fixed on the rack, the transmission rolling shaft driving motor being fixed on frame seat, improvements introduced is:
Adhere to one layer of internal layer screen drum, internal layer screen drum and former screen drum in screen drum and forms inside and outside two layers of the screen drum mutually to recline, two layers of screen drum
Between can opposite sliding, sieve pore on internal layer screen drum and the sieve pore position on outer layer screen drum are corresponding, aperture is identical, in inner layer screen
The fixed internal layer screen drum opposed outer layer screen drum rotation urging and locked component for stretching out outer layer screen drum on cylinder.
It is attached in internal layer screen drum outer surface to avoid causing adjustment laborious due to the frictional force between screen drum inside and outside corrosion makes increases
Stainless steel or resin slide guide layer.Slide guide layer material preferably polytetrafluoroethylene.
The force component preferred structure of internal layer screen drum opposed outer layer screen drum rotation of the present invention is by being fixed on inner cylinder outer surface
One section of wrom tooth and be fixed on outer screen drum, through on outer screen drum hole and wrom tooth be meshed worm screw composition.
In the present invention, the locked component between inner barrel and outer barrel is preferably fixed on internal layer screen drum, through the circle on outer layer screen drum
Stretching out the screw rod of outer layer screen drum to strip-shaped hole and being fitted on the nut on screw rod in outer layer screen drum exterior on week forms.
For screen size classification of the installation and adjustment realization convenient for internal layer screen drum on same screen drum, the inner layer screen
Cylinder is preferably divided into several sections of settings in the axial direction.The force component of rotation rotation is separately provided in every section of internal layer screen drum opposed outer layer screen drum
And locked component.
For the sorting function for further promoting screening machine of the invention, realizes and sieves the light, heavy burder separating piled of material thoroughly,
The falling stroke installation sorting blower of the corresponding material of sieve thoroughly in the front of rack or rear portion.Opposite sorting blower stream it is another
Side installation prevents lightweight object from drifting baffle, the baffle top dog-ear, has the mistake air holes for reducing windage in baffle plate face.
For the tilt angle for selecting screen drum output end downward under different material state, another improve of the invention is rack
It is made of forward and backward column and the frame ellbeam with stud connection in forward and backward the upper end of the column carrying screen drum, rear column therein or preceding
The height regulating mechanism that column is made of threaded rod and screw shell, forward and backward column peace is to having brace, oblique pull between frame
The length adjusting mechanism for thering is threaded rod and screw shell to constitute on muscle.
In use of the invention: the sieve pore of inside and outside layer screen drum being completely coincident, inside and outside layer screen drum is passed through fastener phase
The screen size of fastening, whole screen drum is maximum, sieves the material of the largest particles in this screening machine screen size range of setting.It is logical
Cross the diameter between internal layer screen drum opposed outer layer screen drum rotation urging component rotation internal layer screen drum adjustment internal layer screen drum opposed outer layer screen drum
To angle, the sieve pore of ectonexine screen drum is made to misplace, so that the sieve pore of two layers of screen drum is superimposed face and reduce, is reduced to corresponding quasi- screening
The granularity of material, fastening locking ectonexine screen drum, can to smaller particle material in this screening machine screen size setting range into
Row screening.
The positive effect of the present invention is: by increasing internal layer screen drum in existing rotary screen, internal layer screen drum opposed outer layer sieves
The rotation urging mechanism of cylinder, the mutual retention mechanism of ectonexine screen drum, realize big ditty of the sieve pore of screen drum in setting range
Whole transformation.Varigrained material is sieved with a screening function.Screening machine granularity adaptation range is expanded, reducing equipment makes
With the equipment investment of side, production cost is reduced.
