In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, right with reference to the accompanying drawings of the specification
A specific embodiment of the invention is described in detail.
In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention, but the present invention can be with
Implemented using other than the one described here other way, those skilled in the art can be without prejudice to intension of the present invention
In the case of do similar popularization, therefore the present invention is not limited by the specific embodiments disclosed below.
Secondly, " one embodiment " or " embodiment " referred to herein, which refers to, may be included at least one realization side of the invention
A particular feature, structure, or characteristic in formula." in one embodiment " that different places occur in the present specification not refers both to
The same embodiment, nor the individual or selective embodiment mutually exclusive with other embodiments.
Referring to Fig.1,2, it is one embodiment of the present of invention, this embodiment offers air inlets under one kind with built-in assembled highly-effective
Select the New-type vertical mill of powder.The New-type vertical mill includes selecting powder unit 100 and grinding unit 200, and the two assembly is one
Body can synchronize realization and select powder and grinding function, and integrated level is higher, and structure is more compact, and required installation space is smaller.
Specifically, selecting powder unit 100 comprising level-one powder selecting part 101 and second level powder selecting part 102, the two are respectively used to just
Step select powder and it is secondary select powder, the fine powder preliminary screening in material can be separated.Wherein, level-one powder selecting part 101 includes position
Central lumen 101a immediately below second level powder selecting part 102 and the outer rim chamber of the circumferentially equidistant distribution along central lumen 101a
101b, central lumen 101a are hollow cylindrical structure.Preferably, outer rim chamber 101b is along the circumferentially equidistant of central lumen 101a
Four groups are distributed with, and the inside of each outer rim chamber 101b is connected to the inside of central lumen 101a.
Outer rim chamber 101b includes external first shell 101b-1 and the first sky in first shell 101b-1
Between 101b-2, the first space 101b-2 can divide into feed zone 101b-21 and air inlet area 101b-22, and the two interconnects,
It can be passed through in central lumen 101a.
There is feed inlet 101c and air inlet 101d, feed inlet 101c to be located at feed zone for the outer end of outer rim chamber 101b
The external port of 101b-21, air inlet 101d are located at the external port of air inlet area 101b-22.Material can be from four feed inlet 101c
Put into corresponding feed zone 101b-21, meanwhile, air inlet area 101b-22 can external blower, air duct, and to air inlet area 101b-22
Inside blast air-flow, air-flow enter after feed zone 101b-21 can aid in level-one powder selecting part 101 tentatively select powder, and by material
It is blown into central lumen 101a.
Further, it is arranged with scattering and grading blade 101e in feed zone 101b-21, can be flap-like, and by upper
And lower arranged distribution has multilayer, the material fallen from feed inlet 101c by multiple scattering and grading blade 101e screening layer by layer it
Afterwards, the material of greater particle size can directly slide into grinding unit 200 and continue to grind, and remaining material enters central lumen with the wind
In 101a, realizes and tentatively select powder.Substantially occur two states, grain under the impact of air-flow into the material in central lumen 101a
Diameter time big material, which is fallen directly into the grinding unit 200 of lower section, to be continued to grind, and the smaller material of partial size can be in air-flow
Impact is lower to realize rolling, and on influx in the second level powder selecting part 102 on top.
In the present invention, second level powder selecting part 102 includes external second shell 102c and is located in second shell 102c
Second space 102d, second space 102d and central lumen 101a inside formed be connected to.In addition, second level powder selecting part 102
Upper end have fine powder discharge port 102a, lower end have coarse powder discharge port 102b, second space 102d respectively with fine powder discharge port
102a is connected to coarse powder discharge port 102b, and second shell 102c is fixed on the top of central lumen 101a.
Further, rotor cage 102e is additionally provided in the second space 102d of second level powder selecting part 102.Rotor cage 102e is
The structure of caged is fixed on vertically in second space 102d, and the interior material from central lumen 101a can pass through rotor cage
102e progress is secondary to select powder, and finally, qualified fine powder can be taken out of from the fine powder discharge port 102a of upper end, and coarse powder is then due to weight
Power effect enters in grinding unit 200 by the fine powder discharge port 102a of lower end carries out further grinding work.
In the present invention, grinding unit 200 is fixed on the lower end of central lumen 101a, and coarse powder discharge port 102b is downwardly into
The inside of grinding unit 200.Grinding unit 200 includes milling chamber 201, bearing assembly 202 and grinding roller component 203.
Specifically, milling chamber 201 is columnar hollow cavity, bearing assembly 202 is horizontally disposed turntable, horizontal
It is installed on the bottom in milling chamber 201, and is able to carry out horizontal revolving motion.Grinding roller component 203 includes external rocker arm
The 203a and grinding roller 203b for being fixed on the upper end rocker arm 203a, grinding roller 203b is protruded into milling chamber 201, and and bearing assembly
202 upper surface contact.Grinding roller 203b is idler wheel shape, and can be rotated.Coarse powder from coarse powder discharge port 102b enters
It is directly fallen on bearing assembly 202 after milling chamber 201, if starting bearing assembly 202 and grinding roller 203b at this time, so that both
Respective rotation occurs, plays the role of grinding coarse powder.When coarse powder is milled into fine powder, fine powder acts on quilt due to mill centrifugal force
It throws away, enters follow-up system therewith.
Further, grinding unit 200 further includes transmission component 204, and transmission component 204 can drive bearing assembly 202
It is rotated.Transmission component 204 can use motor, can be attached by the bottom of speed reducer and bearing assembly 202
And be driven, control its horizontal rotation.
Compared with current most of mill structures, innovative point is the present invention: there is no vane in mill, equipment resistance is lower,
Energy-saving effect is obvious；For equipment combination of sets at Du Genggao, structure is more compact, and required installation space is smaller；Four lower air inlet edges
Circumferential 360 ° uniformly distributed, makes, grinding efficiency height more uniform by the air quantity containing fine powder of rotor cage, and cost is lower.
