Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a roller side seal plate for a roller compactor for forming fine powder (for example, coke powder, CaO powder, etc.) into a band or flake having a high bulk density. The present invention relates to a holding device.

[Prior Art] In a conventional roller compactor, as shown in FIG.
The fine powder raw material 2 in the hopper 1 is fed to the roller rolling machine 4 while increasing the bulk density by the rotation of the screw feeder 3. The fine powder compressed by the roller 5 is solidified into a plate shape and sent out from the roller.

When the fine powder is fed from the screw feeder casing 6 to the roller, the fine powder does not leak outside,
Upper and lower roller seal plates 7 and 7'which are in contact with the roller surface and have the same width as the roller, and roller side seal plates 8 and 8'which are in contact with the roller side faces are attached to the screw feeder casing 6 to form a closed box and leak. Is being prevented. Since these seal plates 8 and 8'are in contact with the rotating roller 5 and are abraded by the fine particles that enter between them, a wear adjusting function is required. Therefore, in the conventional roller compactor, wear adjustment is performed by a roller side seal plate pressing device.

The conventional roller side seal plate pressing device is a direct screw type as shown in FIG. 4 (shown in the AA cross section of FIG. 5), and if the head 10 of the pressing screw 9 is turned counterclockwise with a spanner. , Roller side seal plates 8 and 8'are rollers 5
It is pressed to the side and the gap with the roller 5 is adjusted.

[Problems to be solved by the device]

In the conventional roller seal plate pressing device, in order to perform adjustment work, it is necessary to put a hand deep inside the narrow space between the bearing box 14 and the roller side seal plates 8 and 8 ', and in that position, the roller end face and the roller Since the contact state with the side seal plate cannot be visually observed, there are places where the operator cannot rely on the intuition of the worker, and proper adjustment required skill. Further, since the fine powder raw material spills into the space and sometimes the space is filled with the raw material, the raw material adheres to the exposed screw part, and abnormal force is required during maintenance or adjustment work. There was a problem that caused problems such as doing. The present invention aims to solve these problems.

[Means for solving the problem]

According to the invention, a wedge piece that slides in parallel with an end surface of a roller, a guide box that guides the movement of the wedge piece, a feed screw extending in a sliding direction that serves to slide the wedge piece, and an end surface of the roller. It is intended to achieve the above-mentioned object by providing a wedge fixed to the outside of the roller side seal plate facing the above and abutting against the wedge piece.

[Action]

A guide box is provided in the peripheral portion of the bearing box, and when the feed screw protruding from the guide box is rotated in a predetermined direction, the wedge piece slides along the inner surface of the bearing box. Then, the wedge piece presses the wedge and moves the roller side seal plate toward the end face of the roller, so that the gap between the end face of the roller and the seal plate is adjusted.

At this time, since the rear end portion of the feed screw is located in the peripheral portion of the bearing box, the rotation operation of the feed screw can be easily performed.

〔Example〕

An embodiment of this invention will be described with reference to the accompanying drawings. As shown in FIG. 1, the roller side seal plates 8 and 8'are brought into contact with the end surface 5a of the roller 5. The seal plates 8 and 8 ′ are fixed to the screw feeder casing 6. The sealing plate 8,
A wedge 13 is formed on the outside of 8 '. The wedge 13 is in surface contact with a wedge piece 15 having an L-shaped cross section. One end of the wedge piece 15 is screwed into the feed screw 16 in the guide box 17. The guide box 17 is fixed to the peripheral portion of the inner surface of the bearing box 14, and the rear end 16a of the feed screw 16 projects from the guide box 17. A loosening prevention nut 18 is screwed onto the rear end 16a of the feed screw 16, and a recess 16b for driver engagement is formed on the end face thereof.

Next, the operation of this embodiment will be described. When the tip of a screwdriver is fitted into the recess 16b of the feed screw 16 and the feed screw 16 is rotated in a predetermined direction, the wedge piece 15 slides horizontally along the inner surface of the bearing box 14 while being guided by the guide box 17. , The surface-contacting wedge 13 is pressed toward the end surface 5a of the roller. Therefore, the seal plates 8 and 8 ′ move toward the end surface 5a of the roller, so that the gap between them is adjusted.

As the feed screw 16, a left screw is used as shown in FIG. 2, but the feed screw 16 is not necessarily limited to this, and a right screw and a left screw may be used as shown in FIG. Since the present invention is configured as described above, the recess at the screw end is
It can be installed by popping out from the bearing box. Therefore, it is not necessary to insert a hand deeply in the back at the time of adjustment, and since it is possible to make an adjustment while directly looking at the contact state between the roller side seal plate and the roller end surface, the adjustment work is extremely simple and even an unskilled person can make an appropriate adjustment. Further, since the screw portion is hermetically sealed by the guide box and the wedge piece, there is no obstacle that the raw material adheres, and the contact surface of the wedge maintains a flat contact, so that the raw material does not enter here. Further, the two wedges are in contact with each other and have a long life against wear, and can perform a stable operation without uneven contact.
