Abstract
The invention relates to the technical field of vertical roller mills, and discloses a fed material buffering and material bed stabilizing device of a vertical roller mill to solve the practical problem that a material bed is instable due to fed material impact, and the milling efficiency of the vertical roller mill is affected. The fed material buffering and material bed stabilizing device of the vertical roller mill is detachable, simple in design, easy and convenient to install and easy to operate. The fed material buffering and material bed stabilizing device of the vertical roller mill comprises upper skirt boards and lower skirt boards, wherein the upper skirt boards are arranged at the lower end of a vertical roller mill discharge chute and used for buffering materials, and the lower skirt boards are arranged at the lower ends of the upper skirt boards and used for guiding the materials into place. A through hole allowing a feed chute to penetrate through is formed in one upper skirt board. The feed chute penetrates through the upper skirt board and extends into a cavity defined by the upper skirt board. The lower end of the vertical roller mill discharge chute is connected with the upper skirt boards through a square flange. According to the vertical roller mill fed material buffering and material bed stabilizing device, the materials can be gently and uniformly scattered onto an abrasive disk due to the buffering effect of skirt boards at the bottom of the device; under the effect of centrifugal force, the materials are uniformly spread apart to enter the grinding area of a grinding roller; and in this way, a material bed can be stabilized, and the grinding efficiency can be improved.
Description
Technical field
The invention belongs to vertical mill technical field, more particularly to a kind of stable bed of material device of vertical mill feed surge.
Background technology
Vertical mill is equipped with technology the twenties in 20th century by Germany's invention, its widespread popularity, economy and stability
The proof of industrial practice is obtained, has been one of first-selected energy-conservation equipment of current grinding field.China initially introduces vertical mill, mainly
For the grinding of the materials such as the cement slurry of cement industry, raw coal, gypsum, due to the superiority of its high yield and low cost, take gradually
For ball mill in the status of cement industry.
At present vertical mill is also used for machining of non-metallic ore deposit, such as calcite, pyrophillite etc., superfine powder is produced, as nothing
Machine filler is used.From vertical mill principle, carry out selecting powder to Vertical Mill top powder concentrator by wind band through the material of grinding, do not conform to
The meal of lattice impacted by rotor of powder separator after because gravitational settling falls into ash bucket, finally drop down onto mill central authorities, the material with new feeding
Again by grinding.Because feeding chute is oblique insertion, the material of feeding directly rushes to mill, is easily caused material and is stacked into rapidly
Mill edge, causes the inhomogeneities for expecting bed.Due to thickness of feed layer change fluctuation greatly, cause grinding machine vibration big, have impact on grinding machine
Grinding efficiency and operational stability.
The content of the invention
The invention aims to reduce because feeding impact causes the reality of the unstable impact mill grinding efficiency of the bed of material to be asked
Topic, the present invention devises a kind of stable bed of material device of vertical mill feed surge, and the device is detachable, and design is simple, installs
Simplicity, easily operation.
To achieve these goals, the technical solution used in the present invention is：
A kind of stable bed of material device of vertical mill feed surge, including located at vertical mill emission of baiting chute lower end for buffering material
Upper skirtboard, located at upper skirtboard lower end be used for directing material in-position lower skirtboard, be provided with one of plate of upper skirtboard
For the through hole that feeding chute is passed through, feeding chute arranges and extends to the inside cavity that skirtboard is surrounded through upper skirtboard.
Connected by square flange between vertical mill emission of baiting chute lower end and upper skirtboard, the welding blanking of square flange upper end
Elephant trunk, the upper skirtboard of square flange lower end welding, is welded with least one reinforcement between emission of baiting chute periphery and square flange
Plate.
Described upper skirtboard is four, and surrounds a cover body, and upper skirtboard generally isosceles trapezoidal structure, it is two neighboring on
It is welded as a whole between skirtboard, welds between feeding chute and upper skirtboard.
Described lower skirtboard is rectangle structure, is welded between adjacent twice skirtboards, the upper skirtboard of lower skirtboard and upper end it
Between weld, the equal length of lower panel length and upper skirtboard lower end.
Described vertical mill emission of baiting chute diameter is less than any value between square flange length of side 120-150mm.
Described lower skirtboard lower end is to the distance between mill more than 2-3 times of most aniseed grain diameter.
Beneficial effects of the present invention：After material feeds Vertical Mill by feeding chute, material is in scoop device for the present invention
（Overskirt plate shape into space in）Buffered, while it is well mixed drop down onto again mill with time powder of ash bucket, because of bottom skirtboard
Cushioning effect, material gently can be equably trickled down to mill, and under the action of the centrifugal force, material is uniformly let go into grinding roller grinding
Area, this measure is conducive to the bed of material to stablize, and lifts grinding efficiency.

Specific embodiment
With reference to embodiment, the present invention will be further described.
Embodiment
The stable bed of material device of a kind of vertical mill feed surge as shown in Figure 1-Figure 3, including located at vertical mill emission of baiting chute
The upper skirtboard 3 for buffering material of the top of lower end mill 5, it is used for the skirt of directing material in-position located at upper skirtboard lower end
Plate 4, is provided with the through hole passed through for feeding chute 1 on one of plate of upper skirtboard, and feeding chute 1 is arranged simultaneously through upper skirtboard
Extend to the inside cavity that skirtboard is surrounded.Connected by square flange 2 between vertical mill emission of baiting chute lower end and upper skirtboard,
Weld emission of baiting chute, the upper skirtboard of square flange lower end welding, between emission of baiting chute periphery and square flange in square flange upper end
It is welded with least one reinforcement gusset.Described upper skirtboard is four, and surrounds a cover body, and upper skirtboard generally isosceles trapezoid
Structure, is welded as a whole between two neighboring upper skirtboard, welds between feeding chute and upper skirtboard.Described lower skirtboard is rectangular
