Description

[Detailed description of the invention] [Industrial application field] The present invention is applicable to devices such as particle shape adjusters and impact crushers that distribute the material to be processed, which is supplied from above, by discharging it horizontally in the radial direction. Regarding triviewer.

[Prior Art] Conventionally, this type of distributor has
For example, a distributor for a crushing device is known, which is disclosed in Japanese Patent Publication No. 53-33785.

FIG. 3 is a plan view of a rotor provided with a distributor of such a crushing device.

In FIG. 3, inside the rotor 1 attached to the upper end of the vertical rotation axis, a distributor 2 is provided at the center of the rotor 1, and blades 3, 4 and 4 rotate around the distributor 2 as the center of rotation. 5 is arranged, and a tip wing 6 is integrally fixed to the tip of the wing 5 to which a carbide tip is attached to protect the tip from wear.

The processed material supplied from the supply device is placed onto the distributor 2, and the blades 3 and 4 are moved by centrifugal force.
and 5 from the tip blade 6 to the discharge port 7,
It is ejected horizontally to the outside of the rotor 1.

The distributor 2 is a conical rotating body having an open top and a bottom, and is made of a wear-resistant material.

When the object to be processed is placed onto the distributor 2, the flow direction of the object is changed to a horizontal direction at the top surface, and the object is moved toward each of the blades mentioned above.

[Problems to be Solved by the Invention] However, the conventional distributor of the grain shape adjuster described above has the following technical problems.

(1) As the distributor rotates, when the material to be processed is thrown in, it instantly flies and flows in the circumferential direction due to the high circumferential speed of the distributor. A dead stock is no longer formed, and the distributor suffers significant wear due to collision with the workpiece.

(2) Since a dead stock is not formed in the distributor, the object to be processed collides violently with each blade without attenuating its kinetic energy, resulting in significant wear of each blade.

(3) Significant wear on the distributor and each blade not only reduces the ability to adjust the particle shape of the object to be treated, but also impedes smooth operation of the device.

The present invention solves these conventional problems by providing excellent grain shape adjustment that reduces wear on the cylindrical body by forming a reliable dead stock in the annular path when the material to be treated is introduced. The purpose is to provide a distributor for machines.

[Means for Solving the Problems] In order to achieve the above object, the present invention is a distributor for a grain shape adjuster that is installed at the center of a rotor attached to the upper end of a vertical rotating shaft, and the top surface is open. A radial blocking member is provided on the annular part of a concentric cylindrical body having a rounded bottom, and a connecting means for connecting to a vertical rotating shaft is provided in the center of the cylindrical body with an insertion part for a pulling tool. This is what I did.

[Function] The present invention has the following effects due to the above configuration.

When the material to be processed is thrown in, its flight in the annular path is blocked by the blocking member, and a dead stock is formed while the flow is changed in the horizontal direction and the material is moved. can be reliably protected.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 is a plan view of a distributor of a grain shape adjuster, and FIG. 2 is a sectional view taken along the line A-A in FIG.

In FIGS. 1 and 2, numeral 10 denotes a distributor, which functions almost in the same way as the distributor 2 described in FIG. 3 above.

The distributor 10 consists of concentric cylindrical bodies 15 and 16 having open top surfaces 11 and 12 and bottom surfaces 13 and 14.
An annular passage 17 formed between 16 is provided with a plurality of blocking members 18 arranged radially.

The height of the top surface 11 of the cylindrical body 15 is slightly higher than the height of the top surface 12 of the cylindrical body 16, so that the object to be processed can easily move to the outside of the distributor 10. . Further, the height of the top surface of the blocking member 18 matches the height of the top surface 12 of the cylindrical body 16. The center portion of the bottom surface 13 of the cylindrical body 16 is provided with joining means 20, 20 for connecting to the vertical rotation shaft, and the joining means 20 may be a screw fastener or the like.
Reference numerals 21 and 21 indicate the insertion portions of the lifting tools provided in the joining means 20. When the distributor 10 becomes worn out and needs to be replaced with a new one, the pulling tools are inserted into the insertion portions 21, 21. This allows for easy attachment and detachment from the vertical rotating shaft by pulling up the lifting tool. Reference numeral 22 denotes the back surface of the distributor 10, which forms a mounting surface for the upper end of the vertical rotation shaft. 19 indicates the surface opposite to the bottom surface 14;
An edge 23 is provided on the surface 19 to prevent dust generated during operation of the particle shape adjusting machine from moving toward the vertical rotation shaft side.

Next, the operation of the above embodiment will be explained. In the embodiment described above, the distributor 10 is rotated with the rotation of the vertical rotation axis, and when the workpiece supplied from the supply device is put onto the distributor 10, the central part of the cylindrical body 15 and the annular path are 17, and in particular, the objects to be processed in the annular path 17 are prevented from flying in the circumferential direction at high speed by the blocking member 18 to form a dead stock. It flows as a surface flow while being deposited, converts the flow in the horizontal direction, moves toward each blade provided on the rotor, collides with it, and is discharged outward from the discharge port.

As described above, according to the above embodiment, when the object to be processed is placed on the distributor, the blocking member 18 prevents the object from instantaneously flying and flowing in the circumferential direction from within the annular path. Since a dead stock can be formed by the material to be treated, the top surfaces 11 and 12 of the cylinders 15 and 16 are covered with the dead stock, which protects the cylinders 15 and 16 from significant wear and reduces wear. can be reduced.

Since a dead stock is formed in the distributor 10, the kinetic energy of the object to be processed is attenuated and it collides with each blade of the rotor, thereby reducing the occurrence of significant wear on each blade.

Since the cylindrical bodies 15, 16 and their respective blades are not deformed by significant wear, it is possible to avoid interfering with the particle shape adjustment function of the processed material and the smooth operation of the apparatus.

The coupling means 20 is provided with an insertion part 21 for a pulling tool, so when the distributor 10 becomes worn out and you want to replace it with a new one, insert the pulling tool into the insertion parts 21, 21, By pulling up the lifting tool, it can be easily attached and detached from the vertical rotating shaft, and the work time for replacement can be shortened.

[Effects of the Invention] As is clear from the above embodiments, the present invention can protect the cylindrical body from wear because the top surface of the cylindrical body of the distributor can be covered with the dead stock of the workpiece. Furthermore, the occurrence of wear on the rotor blades can be reduced. Therefore, it is possible to avoid interfering with the particle shape adjustment function of the object to be treated and the smooth operation of the apparatus. Moreover, when the wear of the distributor progresses, replacement work can be facilitated, and the work time can be shortened, which has many practical effects.
