Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wet particle shape adjusting device for wetly adjusting the particle shape of a material.

[Conventional technology]

Conventionally, as this type of wet particle shape adjusting device, it is known to use, for example, a crushing device described in Japanese Patent Publication No. 53-33785.

That is, in FIGS. 4 and 5, inside the rotor 1 mounted on a vertical rotation shaft via a bearing 2, a distributor 20 is provided in the center of the rotor 1, and a distributor 20 is provided in the center of the rotor 1. a wing 21 that rotates around the tributator 20;
22 and 25 are arranged in an asymmetrical manner to form a discharge path, and a tip wing 24 is integrally fixed to the tip of the wing 25 to which a carbide tip 24a is attached to protect the tip from wear. has been done.

The material supplied from the supply device 11 is put onto the distributor 20 and distributed to the discharge path,
Due to centrifugal force, it is sent from the tip blade 24 to the discharge port 19 through a discharge path made up of blades 21, 22, and 25, and is discharged horizontally to the outside of the rotor 1. The ejected material impinges on a dead stock 15 formed as an impingement part inside the housing 8 containing the rotor 1. In this way, the collision of the materials with each other removes the sharp corners of the materials and adjusts the grain shape.

For the wet particle shape adjustment device, the above materials include:
A mixture of material and water is used to shape and wash the particles, and the mixture is then substantially
The material, which is separated into material and water, whose particle size is adjusted and washed, is used for many purposes.

[The problem that the idea attempts to solve]

However, the conventional wet particle shape adjusting apparatus described above has the following technical problems. That is, 1. When the mixture moves through the discharge path of the rotor,
In the curved portions of the asymmetrically formed wings 22, 25,
Since the mixture is discharged while being deposited, the smooth flow of the mixture is obstructed, and the collision action with the collision part becomes unstable, making it impossible to adjust the grain shape of the mixture.

2 The mixture discharged to the outside of the rotor collides with the dead stock 15 to adjust the grain shape, so the deposition state of the dead stock 15 forming the collision area depends on the material properties, concentration of the mixture, and operating conditions of the device. will fluctuate significantly,
Similarly to the above, the collision effect with the collision part becomes unstable. Therefore, good particle shape control of the mixture cannot be achieved.

The present invention solves these conventional problems by promoting smooth flow of the mixture, avoiding the occurrence of unstable collision-abrasive action, and achieving good particle shape adjustment.
The object of the present invention is to provide an excellent wet particle shape adjustment device that can achieve a cleaning action.

[Means to solve the problem]

In order to achieve the above object, the present invention is a wet particle shape adjusting device for wetly adjusting the particle shape of a material. A rotor that is equipped with a supply device for supplying the mixture in the radial direction, a distributor and a discharge passage for distributing the mixture supplied from the supply port to the discharge passage, and that applies centrifugal force to the mixture and discharges the mixture horizontally in the radial direction. and an upper casing having an annular polishing chamber provided concentrically around the outer periphery of the rotor to cause the mixture discharged from the rotor to flow in an arc shape from below to above; The lower casing is connected to the lower casing and has an outlet in the vertical axis direction for discharging the product.

[Effect]

The present invention has the following effects due to the above configuration. In other words, when the mixture is introduced into the rotor rotating at high speed from the supply port, it is evenly distributed to each discharge path by the distributor, and the discharge paths formed in symmetrical passages are smoothly distributed. This ensures that the mixture flows in an arc shape within the annular polishing chamber, avoiding its accumulation, and the particle shape is adjusted by mutual collision and polishing, and the sharp edges of the materials in the mixture are scraped off. At the same time, the top soil and other impurities adhering to the material are removed, resulting in a cleaned preparation that is discharged from the discharge port.

In the above embodiment, the respective flow rates are adjusted so that the mixture is 50% by weight of the material and 50% by weight, and the mixture is supplied from the supply port 31 into the upper casing 49 at high speed. When placed on the distributor 34 of the rotating rotor 45, the central portion of the cylindrical body 63 and the annular path 64
By filling the inside of the annular path 65 and preventing the mixture from being scattered from inside the annular path 65 by the blocking member 65, a sufficient dead stock is formed on the surface of the distributor 34 while converting the flow in the horizontal direction. The mixture is then uniformly distributed and introduced into the discharge channel 43 in the rotor 45 .
The mixture moves smoothly in the radial direction O-R without being deposited, and is discharged from the discharge port 45 toward the outer circumferential direction into the annular polishing chamber 48, so that the arc-shaped flow of the mixture is smoothly repeated.

In this way, according to the above embodiment, the rotor 41
The mixture supplied to is uniformly guided into the discharge path 43 and moves within the discharge path 43 without being deposited,
Since a smooth flow is formed, the collision and abrasion action in the annular abrasion chamber 48 are performed stably, and the particle shape of the mixture can be well adjusted and cleaning can be performed. In addition, the discharged mixture smoothly repeats arc-shaped flow in the annular polishing chamber 48, which promotes the collision and polishing action, resulting in good granulation of the mixture. Can be cleaned as well as shape adjusted. Furthermore, the top surface of the distributor 34 can be covered with the mixture to protect against significant wear of the cylinder, and the mixture attenuates the kinetic energy impinging on each blade of the rotor 41 to prevent wear from occurring. Since deformation due to abrasion does not occur, it is possible to avoid interfering with particle shape adjustment and cleaning functions and smooth operation.
