Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a vertical crusher, and a method for adjusting a weir (hereinafter referred to as Damryu/G) provided outside the crushing table. and devices.

[Prior art]

In a vertical crusher, the height of the dam ring installed on the outside IM of the crushing table has a great effect on the layer thickness formed between the rollers and the table, and influences the crushing performance. For example, US patent N
There is one described in the o2684813 publication. As shown in No. 1-, the dam ring 1 is fixed to the crushing table 4, so when the raw material properties change, the crusher is stopped and a different size of dam ring is installed in order to obtain the optimum crushing condition. I had to replace it with 1.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a dam ring adjustment method for a vertical crusher that can change the height or overhang amount of the dam ring during operation, and It is to provide the device.

[Structure of the invention]

To explain the features of the present invention with reference to the drawings, the first invention is, as shown in FIGS. 2 to 9, a plurality of crushing rollers 2 are rotatably arranged on a rotating crushing table 4. In the vertical crusher 20, the height or overhang amount of the dam ring 1゜9.21.22 provided on the outer periphery of the crushing table 4 can be changed by a fluid or electric drive device 6. This is a method of adjusting dam rings 1.9, 21.22. As shown in FIGS. 2 to 9, the second invention is a vertical crusher 20 in which a plurality of crushing rollers 2 are rotatably disposed on a rotating crushing table 4. Damring that can be moved freely l, 9, 21
．． 22, and below this dam ring 1, 9, 21.22 there is a connecting fitting 5 for moving the dam ring 1, 9°2'l,
This is a dam ring adjustment device for a vertical crusher, in which a drive device 6 is provided at the bottom of the crushing table 4 via the connecting fitting 5.

〔Example〕

Hereinafter, the present invention will be explained in detail based on examples thereof.

FIG. 2 shows an outline of the overall view in which the dam ring 1 is provided on the vertical crusher 620.

FIG. 3 is an enlarged view of the mounting portion of the dam ring 1 shown in FIG. 2. In this embodiment, the inner peripheral end of the dam ring l is connected to the crushing table 4 so that it can freely vibrate, and a rotatable metal fitting is attached to the lower part near the center of the dam ring 1 and connected to the drive device 6 via a connecting metal fitting 8 to a rod 7. They are connected. The drive device 6 may be of either a fluid type or an electric type, and is fixed to the lower part of the grinding table 4 by a support 10. As a result, the dam ring l is
1- The height in the downward direction can be freely adjusted during operation.

FIG. 4 is different from FIG. 3 only in the shapes of the dowel and ring, and the other parts are the same as in FIG. 3. This is because the dam ring 9 and rod 7 are fixed, and the drive device 6! 1
Due to the X movement, the entire dam ring 9 is translated in parallel in the downward direction by approximately 200 degrees, and adjustment in the vertical direction is performed.

No. 5171, the dam ring 21 moves in the radial direction of the grinding table 4 along the upper end surface of the grinding table 4 to adjust the amount of overhang. In order to make it movable, there are several ring-shaped dam rings). The difference from FIG. 3 is that a connecting fitting 11 is added, and the rest is the same.

FIG. 6 shows an outline of an embodiment in which hydraulic pressure is used to drive the drive device 6. In FIG.

In this figure, the pump 14 is connected to the lower part of the crushing table drive shaft 23 through the piping 12 to the lower part of the crushing table drive shaft 23.
This piping 12 is connected to the lower surface of the crushing table 4 by passing it through the inside of the drive shaft 23, and then connected to the driving device 6. Also, if you use electric power, pump 14! If you change this and use electrical wiring as a control panel, the same drive as described in Section 2 can be achieved. 7th for electric
Electric power can also be supplied by a slip ring 24 as shown in the figure.

Figures 8 and 9 show the dam ring 22 divided into two parts, the first dam ring 15 and the lower dam ring 16, with the mating surfaces of the upper and lower dam rings 15 and 16 tapered as shown in Figure 8. By driving the drive device 6, via the connecting fitting 5,
By moving the crushing table 4 in the circumferential direction, the vertical height of the dam ring 15 can be adjusted.

Although a two-length embodiment has been described above, it goes without saying that even if the shape is different, the invention falls within the scope of the present invention as long as it does not depart from the technical scope of this embodiment.

〔Effect of the invention〕

1. As can be seen from the detailed description, the present invention is a vertical crusher in which the height or overhang amount of the dam ring provided on the outer periphery of the crushing table can be adjusted, so that It becomes possible to adjust the height of the dam ring or the amount of overhang, and it becomes possible to significantly shorten the time required for one driver.

Or even if the raw material properties change during operation.5)
It becomes possible to obtain suitable crushed rods without stopping the crusher.
