Abstract
The invention discloses an online adjustment device for a retention ring of a vertical mill. The online adjustment device comprises a retention plate, a substrate, a limiting block, an abrasive disk and the like, wherein the retaining plate is arranged on the substrate and is connected with the substrate through a chute; the retention plate slides outwards along the direction of the chute under the action of a centrifugal force along with rotation of the abrasive disk; different rotating speeds of the abrasive disk correspond to different heights of the retention plate. The rotating speed of a main motor are adjusted through a frequency converter, the rotating speeds of the abrasive disk are changed, the centrifugal force stressed by the retention plate is adjusted, therefore, the height of the retention ring is adjusted in an online manner, the operation rate of equipment is improved, and the operation and maintenance costs are reduced.
Description
Technical field
The present invention relates to a kind of Vertical Mill blocking material ring, particularly a kind of Vertical Mill blocking material ring is at line adjusting device.
Background technology
The height of Vertical Mill blocking material ring determines the thickness of the mill bed of material, if after the bed of material, can increase the consumption of driving force, can not improve grinding effect; But blocking material ring is too low, and material will overflow outside mill, and the scum amount increases, and the vibration values of grinding machine increases.The adjustment of blocking material ring height can affect the output of grinding machine, power consumption and bed drain purge, and also impact operates control stable simultaneously.At present, the measure of domestic adjustment blocking material ring height is substantially all the off-line adjustment, namely shuts down the whole blocking material ring height of laggard pedestrian's wage adjustment, and this mode operates inconvenience, affects grinding machine running time, and grinding machine opens, shuts down larger power consumption, has increased operating cost.
Summary of the invention
In order to solve problems of the prior art, the object of the present invention is to provide a kind of measure that can adjust online the blocking material ring height, namely adjust the Vertical Mill blocking material ring of blocking material ring height at line adjusting device under the non-stop-machine state of Vertical Mill.
To achieve these goals, the present invention is by the following technical solutions: a kind of Vertical Mill blocking material ring is at line adjusting device, comprise striker plate, substrate, limited block and mill, described striker plate is connected by chute with substrate, and described chute is being crossed on mill diameter and the plane vertical with mill.
Described limited block is positioned at the junction of substrate and mill.
After adopting above technical scheme, of the present invention have a following beneficial effect: along with mill rotates, striker plate outwards slides along the chute direction under the effect of centrifugal force, the striker plate height that different speed of grinding plate is corresponding different.Adjust main motor speed by frequency converter, change speed of grinding plate, adjust the centrifugal force that striker plate is subject to, thereby realized online adjustment blocking material ring height, improved operation rate, reduced the Operation and Maintenance expense.
Description of drawings
Fig. 1 is that a kind of Vertical Mill blocking material ring of the present invention is at the structural representation of line adjusting device.
In figure: 1, striker plate; 2, substrate; 3, limited block; 4, mill.
The specific embodiment
The below is further explained the present invention according to Figure of description and specific embodiment.
As shown in Figure 1, a kind of Vertical Mill blocking material ring comprises striker plate 1, substrate 2, limited block 3 and mill 4 at line adjusting device, and described striker plate 1 is connected by chute with substrate 2, and described chute is being crossed on mill 4 diameters and the plane vertical with mill 4.Along with mill 4 rotates, striker plate 1 outwards slides along the chute direction under the effect of centrifugal force, striker plate 1 height that different mill 4 rotating speeds are corresponding different.Adjust main motor speed by frequency converter, change speed of grinding plate, adjust the centrifugal force that striker plate 1 is subject to, thereby realized online adjustment blocking material ring height.Improve operation rate, reduced the Operation and Maintenance expense.
Described limited block 3 is positioned at the junction of substrate 2 and mill 4.Limited block 1 is arranged on substrate 2, has guaranteed that striker plate 1 does not break away from substrate 2.
Claims (2)
1. a Vertical Mill blocking material ring at line adjusting device, is characterized in that comprising striker plate, substrate, limited block and mill, and described striker plate is connected by chute with substrate, and described chute is being crossed on mill diameter and the plane vertical with mill.
2. a kind of Vertical Mill blocking material ring according to claim 1 at line adjusting device, is characterized in that described limited block is positioned at the junction of substrate and mill.
