Description
Technical field
The present invention relates to Vertical Mill technical field more particularly to a kind of Vertical Mill material guide devices.
Background technique
Vertical Mill is obtained as a kind of main milling equipment in occasions such as grinding raw material, cement, coal dust, slag and steel slags
Widely apply.
In the operational process of Vertical Mill, material is directly slipped down on mill by feed pipe, so with mill rotate and by
It gets rid of to be layered on mill and be milled by grinding roller.Existing this cutting mode, material is more random in the motion profile of mill, and has
A part of material is not milled by grinding roller the phenomenon that being just thrown out of mill, having caused " getting rid of sky ", so that grinding efficiency is not high, energy damage
It loses more.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of Vertical Mill material guide device, " getting rid of sky " is effectively prevented
The generation of phenomenon, improves grinding efficiency.
The technical solution adopted by the present invention to solve the technical problems is: a kind of Vertical Mill material guide device, including feed pipe,
The bottom end of feed pipe is equipped with adapter tube, several deflectors is along the circumferential direction equipped on the outer wall of this adapter tube, between adjacent baffle
Adapter tube be equipped with discharge hole, the quantity of discharge hole and the quantity of deflector are identical.
Embodiment as a further preference, deflector extend from adapter tube outer wall to grinding roller medial surface, outside deflector
Side is not in contact with the medial surface of grinding roller.
Embodiment as a further preference, the deflector are arc.
Embodiment as a further preference, the bottom end of the deflector are less than 10mm at a distance from mill upper surface.
Embodiment as a further preference is additionally provided with the rib mutually connected firmly with corresponding deflector on the outer wall of the adapter tube
Plate.
Embodiment as a further preference, the setting quantity of floor is in arranged up and down two on each deflector
It is a.
Embodiment as a further preference, the quantity of the deflector and the quantity of grinding roller are identical.
Embodiment as a further preference, the discharge hole are located at the side of adapter tube or the bottom end of adapter tube.
Embodiment as a further preference, the adapter tube are removably connected between feed pipe.
Embodiment as a further preference, the deflector are fixed on adapter tube outer wall in the form welded.
The positive effect of the present invention: adapter tube is arranged in the discharge end of feed pipe in the present invention, corresponding using this adapter tube setting
Discharge hole and deflector, material enter the surface of mill from the discharge hole of adapter tube and spread out with the rotation of mill, material paving
Deflector limits motion profile of the material on mill during opening, and enables material total movement to the area that mills of grinding roller
It is milled, avoids partial material without milling and the phenomenon that " being got rid of sky ", effectively increase grinding efficiency.
Detailed description of the invention
Fig. 1 is the side structure schematic view of Vertical Mill material guide device described in preferred embodiment；
Fig. 2 is the overlooking structure diagram of Vertical Mill material guide device described in preferred embodiment.
Specific embodiment
With reference to the accompanying drawing to a preferred embodiment of the present invention will be described in detail.
Referring to FIG. 1 and FIG. 2, the preferred embodiment of the present invention provides a kind of Vertical Mill material guide device, including feed pipe 1, is feeding
The bottom end of pipe 1 is equipped with adapter tube 2, on the outer wall of this adapter tube 2 at 6 opposite position of grinding roller be equipped with several deflectors 3, it is adjacent to lead
Adapter tube between flowing plate 3 is equipped with discharge hole, and the quantity of discharge hole is identical as the quantity of deflector 3.
The medial surface of the extension from the outer wall of adapter tube 2 to 6 medial surface of grinding roller of deflector 3, the outboard end of deflector 3 and grinding roller is not
It is in contact.
The deflector 3 is arc, and the rotation direction of extending direction and grinding roller from inside to outside is on the contrary, even grinding roller
Rotation direction is counterclockwise, then deflector adapter tube outer wall outside extension in a clockwise direction certainly.In addition to arc, deflector can also be with
Select other Irregular Boundary Surfaces or plane.
The bottom end of the deflector is less than 10mm at a distance from mill upper surface, gap is excessive be easy to cause material leakage serious and
The phenomenon that can not avoiding material " getting rid of sky " completely.
Deflector is deformed in order to prevent, and the rib mutually connected firmly with corresponding deflector is additionally provided on the outer wall of the adapter tube
Plate, it is preferred that the setting quantity of floor is in two arranged up and down on each deflector.
The quantity of the deflector 3 is identical as the quantity of grinding roller 6.
The discharge hole is located at the side of adapter tube or the bottom end of adapter tube, the setting of discharge hole define the unloading position of material
And direction, convenient for moving material along deflector.
For the ease of installation and removal, the adapter tube is removably connected between feed pipe.
The deflector is fixed on adapter tube outer wall in the form welded, can also be according to deflector in addition to welding form
The factors such as material select other fixed forms.
Material enters the surface of mill from the discharge hole of adapter tube and spreads out with the rotation of mill, and deflector limits object
Expect the motion profile on mill, and material total movement is enable to be milled to the area that mills of grinding roller, avoids material " getting rid of sky "
The phenomenon that.Deflector is arranged in the space between feed pipe and grinding roller front end simultaneously, will not influence the object after grinding roller is ground
Material throws away mill.
It is above-described to be merely a preferred embodiment of the present invention, it should be understood that the explanation of above embodiments is only used
In facilitating the understanding of the method and its core concept of the invention, it is not intended to limit the scope of protection of the present invention, it is all of the invention
Any modification for being made within thought and principle, equivalent replacement etc., should all be included in the protection scope of the present invention.
