Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a device for supplying crushed material to a media stirring type crusher.

[Conventional technology]

Conventionally, a medium stirring type crusher is one that mixes hard crushing media such as ceramic chips or steel balls placed in a crush tank and crushed material to crush the crushed material, but supplies this crushed material. As the supply section, there is known a structure in which a plug attached to the supply section is rotated to prevent agglomeration of the crushed material, or a structure in which a grate-like screen is attached.

[Problems to be solved by the invention]

However, the former structure has a drawback that the sealing structure of the bearing part of the rotating plug is complicated and the cost is high, and the latter structure uses a ceramic material that does not affect the crushed material. In that case, there is a problem that the manufacturing process is difficult and there is a problem such as damage due to insufficient strength.
It has the drawback that it cannot be made into ceramics.

In view of the above-mentioned conventional problems, the present invention has been made to solve the above problems, and uses a ceramic material that does not affect the crushed material, and allows the crushed material to be smoothly supplied without causing clogging. To get a crusher feeder that can.

[Means for Solving the Problems] As a means for achieving this, the present invention provides a crushed material supply unit with a supply port opened in a tank for pulverization processing, and fits a plug into the supply port. A gap for supplying the crushed material to the tank is formed between the plug and the supply port, and a knocker for giving a vibration impact to the plug is connected to the plug.

〔Example〕

An embodiment of the present invention, which is shown in the drawings, will be described in detail below.

A crusher tank 1 is composed of a bottomed cylindrical body, and a bottom portion 2 thereof is provided with a boss 3 which constitutes a supply portion having an opening for a supply port 4 communicating with the inside of the tank. A nozzle 5 for supplying a crushed material, which has an outlet 6 opened at the supply port 4, is formed in a protruding manner. Reference numeral 7 denotes a plug, which is formed into a cylindrical body made of a ceramic material, is fitted with a gap e capable of supplying a crushed material with the supply port 4 of the boss, and is fitted in the upper half portion of the plug 7. Has a groove 8 having a semicircular cross section formed in a ring shape at a position corresponding to the outlet 6 of the nozzle 5.
Attach the O-ring 9 between the lower part and the boss 3. Further, the protrusion 10 of the metal fitting 10 is attached to the mounting hole 7a formed at the lower end of the plug 7.
Attach a by bonding it with an adhesive. Further, the plug 7 and the metal fitting 10 may be attached with screws instead of the above adhesive. An elastic body 11 such as rubber is interposed between the flange portion 10b of the metal fitting 10 and the lower end of the boss 3, and
The bolt 12 is inserted into the mounting hole 10c formed in the metal fitting 10 and screwed onto the boss 3 to mount the metal fitting 10 on the boss 1. Reference numeral 13 is a knotker, which is fixed to the lower end of the metal fitting 10 by a bolt 14, and the knotker 13 is operated by an air pipe 15 so that it can vibrate up and down.

Reference numeral 16 is an agitator shaft having an agitator arm 17 projecting from it, 18 is a grinding medium loaded in the tank 1, and 19 is a cooling jacket of the tank 1.

With this configuration, the crushed material that has been slurried is the nozzle 5
From the outlet 6, enters the concave groove portion 8 from the outlet 6, is evenly distributed over the entire circumference of the plug 7, and the crushed material is further supplied into the tank 1 through the gap e. The crushed material supplied into the tank 1 is agitated by the rotating agitator arm 17 together with the crushing media 18, crushed between the crushing media 18, and discharged from the upper portion to become a product. During this crushing work, Notsker 13
Air is sent from the air pipe 15 by a timer incorporated in an operation panel (not shown). This makes the Notsker 13
Vibrates up and down for an arbitrary time against the elasticity of the elastic body 11 between the boss 3 and the metal fitting 10. Due to this vibration, the plug 7 integrated with it receives the shock of vertical vibration, and the upper part of the plug 7 and the supply port 4
The crushed material accumulated in the form of a cake between the gaps e and is shaken off, the clogging of the crushed material is prevented, and the crushed material is smoothly supplied to the tank 1.

Although the knocker 13 is operated by air in the above embodiment, the invention is not limited to this.

[Effect of device]

As described above in detail with reference to the embodiments, according to the present invention, since the plug attached to the crushing material feeder is periodically impacted by a knocker, crushing particles that try to be deposited in a cake shape in the gap between the plug and the tank are crushed. The material is reliably shaken off, and it is always kept in a clean state to prevent clogging of the material and to supply the material to the tank smoothly. Further, since the plug is not rotated unlike the conventional case, the bearing part can be easily sealed and the cost can be reduced, and the plug can be formed in a simple shape, so that it can be made ceramic. It has the effect of being able to do so.
