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 on-line tuning device.
Background technology
The height of Vertical Mill blocking material ring determines if after the bed of material, can increase the thickness of the mill bed of material consumption of driving force, can not improve grinding effect; But blocking material ring is too low, material will overflow outside mill, and 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 the stable of control simultaneously.At present, the measure of domestic adjustment blocking material ring height is substantially all off-line adjustment, and namely shut down laggard pedestrian's work adjustment blocking material ring height, this mode operates inconvenience, affect grinding machine running time, and grinding machine opens, shuts down larger power consumption, adds 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 can the measure of on-line tuning blocking material ring height, under the non-stop-machine state of Vertical Mill, namely adjust the Vertical Mill blocking material ring on-line tuning device of blocking material ring height.
To achieve these goals, the present invention is by the following technical solutions: a kind of Vertical Mill blocking material ring on-line tuning device, comprise striker plate, substrate, limited block and mill, described striker plate is connected by chute with substrate, and grinding wheel diameter in the plane vertical with mill crossed by described chute.
Described limited block is positioned at the junction of substrate and mill.
After adopting above technical scheme, of the present invention have following beneficial effect: along with mill rotates, striker plate outwards slides along chute direction under the influence of centrifugal force, the striker plate height that different speed of grinding plate is corresponding different.By frequency converter adjustment mair motor rotating speed, change speed of grinding plate, the centrifugal force that adjustment striker plate is subject to, thus achieve on-line tuning blocking material ring height, improve operation rate, reduce Operation and Maintenance expense.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Vertical Mill blocking material ring of the present invention on-line tuning device.
In figure: 1, striker plate; 2, substrate; 3, limited block; 4, mill.
Detailed description of the invention
According to Figure of description and specific embodiment, the present invention is further explained below.
As shown in Figure 1, a kind of Vertical Mill blocking material ring on-line tuning device, comprise striker plate 1, substrate 2, limited block 3 and mill 4, described striker plate 1 is connected by chute with substrate 2, and mill 4 diameter in the plane vertical with mill 4 crossed by described chute.Along with mill 4 rotates, striker plate 1 outwards slides along chute direction under the influence of centrifugal force, striker plate 1 height that different mill 4 rotating speeds is corresponding different.By frequency converter adjustment mair motor rotating speed, change speed of grinding plate, the centrifugal force that adjustment striker plate 1 is subject to, thus achieve on-line tuning blocking material ring height.Improve operation rate, reduce Operation and Maintenance expense.
Described limited block 3 is positioned at the junction of substrate 2 and mill 4.Limited block 1 is installed on a substrate 2, ensure that striker plate 1 does not depart from substrate 2.
Claims (1)
1. a Vertical Mill blocking material ring on-line tuning device, it is characterized in that comprising striker plate, substrate, limited block and mill, described striker plate is connected by chute with substrate, described chute is at mistake grinding wheel diameter and in the plane vertical with mill, described limited block is positioned at the junction of substrate and mill.
