Description
Technical field
The present invention relates to vertical roller grinder technical fields, more specifically, it relates to a kind of mill pedestal.
Background technique
Slag vertical-mill charging drops down among mill, a taper material heap is formed, with the rotation of mill, in the work of centrifugal force
Under, gradually scatter to mill periphery, roll area into mill and grinding roller, the finished product or semi-finished product fine powder after milling continue to
Mill edge is mobile, forms a high outside and low outside oblique charge bank, and finished product or semi-finished product fine powder enter blowing ring along this slope and go out
Mouthful, under the effect of high speed hot wind, a part is upwardly into sorting area, and a part becomes downwards returning charge, because containing iron in slag
Sand, the specific gravity of iron is greater than slag, therefore compares slag or slag powders, and iron sand or the iron sand powder by rolling are in mill edge shape
At oblique charge bank in be easy to be deposited on the bottom of charge bank, i.e. the angle that is formed of mill blocking material ring and lining board for grinding discs, and be not easy by
The edge for throwing away mill enters downstream, and the iron sand at this gradually deposits, and causes the reduction of material grindability.
Notification number is that the Chinese patent of CN201921724U discloses a kind of mill of slag vertical-mill, by mill body, liner plate
And blocking material ring, mill body and liner plate outer end are respectively equipped with mill hole and liner plate hole.Hoard iron sand in mineral slags bed most easily
Position exclude iron sand in time, improve the grindability of slag.
Liner plate hole big end under, small end upward, but after liner plate hole plug, can not dredge liner plate hole prevent iron sand from
Timely it is discharged.
Summary of the invention
The object of the present invention is to provide a kind of mill pedestals, reach the mesh of the easy cleaning tamper after liner plate hole plug
's.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of mill pedestal, including mill
Disk body, liner plate and blocking material ring, the mill body and liner plate outer end are respectively equipped with mill hole and liner plate hole, the mill hole and lining
Plate hole communicates, and mill hole aperture is greater than the aperture in liner plate hole, is equipped with the ring being bonded with liner plate hole hole wall in the liner plate hole
Shape thickening ring is equipped with the annular connection ring contradicted with mill hole hole wall in the mill hole, and the internal diameter of the connection ring, which is greater than, to be added
The internal diameter of thick ring, the connection ring upper end are equipped with limit plate of several support thickening rings in liner plate hole, set in the mill hole
The locating part of restricted connection ring position.
By using above-mentioned technical proposal, after solid blockade thickening ring, by releasing limit of the locating part to connection ring
Connection ring is removed out of mill hole, thickening ring loses the support of limit plate at this time, removes out of liner plate hole, and then be easy to use
Person clears up the object blocked in thickening ring, and when furthermore again moving into thickening ring in liner plate hole, thickening ring will be bonded liner plate hole hole wall,
It is convenient after liner plate hole plug that thickening ring is removed into liner plate hole again.
Preferably, the connection ring extends mill hole far from one end of thickening ring, and the locating part includes setting even
Connect ring lower end and the solid plate that is contradicted with mill body lower end wall, be threaded in the solid plate be threadedly coupled with mill body it is tight
Gu screw rod.
Preferably, the limit plate is detachably connected with connection ring upper end, is threaded with connecting rod on the limit plate,
The connecting rod passes through limit plate and connect with connection ring threaded upper ends.
Preferably, the limit plate includes the fixed plate connecting with connecting rod and two first be arranged in fixed plate
Threaded rod is threaded with connection sleeve on each first threaded rod, and each connection sleeve is far from the first screw thread
One end of bar is connected by movable plate, and the connection sleeve and movable plate are rotatablely connected, and the movable plate supports connection ring.
Preferably, the liner plate hole is that upper end aperture is small, and the big bellmouth in lower end aperture, the thickening ring outer wall is equipped with
The stiffening plate in liner plate hole is extended into, the stiffening plate is arranged close to mill hole.
In conclusion the invention has the following advantages: after solid blockade thickening ring, by releasing locating part to even
The limit for connecing ring removes connection ring out of mill hole, and thickening ring loses the support of limit plate at this time, removes out of liner plate hole, into
And the object blocked in thickening ring is cleared up convenient for user, when furthermore again moving into thickening ring in liner plate hole, thickening ring will be bonded
Liner plate hole hole wall, convenient after liner plate hole plug that thickening ring is removed liner plate hole again, structure is simple, and practicability is good.
