Description

[Detailed Description of the Invention] The present invention relates to a media dispersion machine that performs dispersion processing such as crushing, stirring, and dispersion of a material to be processed together with a media in a processing tank.

In general, a media disperser has a plate-shaped, rod-shaped, or other rotary blade attached to a drive shaft provided in a processing tank, and an end of the drive shaft is extended from one end of the processing tank, and a shaft sealing member is inserted between the drive shaft and the processing tank. However, since the shaft sealing member and bearing member are directly attached to the drive shaft, these parts must be repaired or replaced. Sometimes, it is necessary to remove the entire drive shaft from the processing tank, which is extremely troublesome, time consuming, and time consuming.

In order to solve such drawbacks, the present invention relates to a media dispersion machine in which a sleeve is integrally fitted onto a drive shaft on which rotary blades are attached, and a shaft sealing member, a bearing member, etc. are provided on the sleeve. When repairing or replacing a member, etc., the work can be easily carried out by simply removing the sleeve without having to take out the drive shaft from inside the processing tank.

Embodiments will be described below with reference to drawings showing embodiments.

In the figure, a horizontal media dispersion machine is shown, but it can also be applied to a vertical dispersion machine, etc. The treatment tank 1 has a jacket 2 around it, and an inlet 3 for the material to be treated and a media dispersion machine at one end. It has an end plate 5 having an outlet 4 and is supported by a main body 6. An intermediate member 8 is fixed to a mounting flange 7 formed on the processing tank 1. A cassette-type screen 9 is provided on the intermediate member 8, and a discharge port 1 is connected through the screen 9.
It is connected to 0. An end plate 11 for closing the processing tank 1 is fixed to the other side of the intermediate member 8, and the end plate is fixed to a frame 12 provided on the main body 6. A horizontal rod 14 whose one end is fixed to the side wall of the processing tank 1 and whose lower surface is supported by a roller 13 passes through the frame 12 to guide the removably held processing tank.

Inside the processing tank 1, there is a drive shaft 16 having plate-shaped, rod-shaped or other stirring blades 15, one end of the drive shaft 16 extends outside the processing tank, and a pulley 17 is attached to the tip. , is rotated by a motor (not shown). A sleeve 18 is removably fitted onto the outer periphery of the drive shaft 16 so as to rotate integrally with the drive shaft. The sleeve has one end inclined obliquely 20 so as to engage with a tapered surface 19 formed on the drive shaft 16, and the other end has a conical wedge piece 21 formed on the other end of the sleeve 18, which connects the inclined surface 22 and the drive shaft. axis 16
The sleeve 18 is fitted onto the drive shaft 1 by tightening the nut 23 on the side surface of the wedge piece 21.
It is fixed integrally by pressing against the tapered surface 19 of 6. The sleeve 18 is provided with a bearing member so as to be rotatably supported by the frame, and is also provided with a shaft sealing member to prevent the material to be processed from leaking on the side facing the processing tank. In the figure,
Bearings 24, 24 such as ball bearings are used as bearing members.
are attached to the frame 12 via the bearing box 25 as appropriate,
Although a mechanical seal 26 is attached to the processing tank side as a shaft sealing member, any other suitable structure may be used. Various known mechanical seals can be used as the mechanical seal, and it is attached to the sleeve so that it can be removed from the sleeve for repair or replacement when the sliding surface 27 becomes worn out due to use.

When the drive shaft 16 is rotated through the pool 17, the sleeve 18 fitted onto the drive shaft is supported by the bearing member and rotates together with the drive shaft. The stirring blade 15 attached to the drive shaft converts the material to be processed supplied from the inlet 3 into a suitable medium (not shown) such as steel balls, glass, ceramics, zircon, etc.
Dispersion treatment is carried out by stirring together with the above ingredients. At this time, even if a large load is applied to the drive shaft, since the sleeve and the drive shaft are integrally fixed by the wedge piece, the drive shaft will not idle. The material to be processed is taken out through a discharge port 10 through a cassette-type screen 9. When repairing or replacing the bearing member or shaft sealing member, the sleeve 18 can be easily separated from the drive shaft 16 by removing the nut 23 and wedge piece 21, so remove the end plate, etc., and move the processing tank. A bearing member, a shaft sealing member, etc. can be attached and detached from the outer periphery of the sleeve.

The present invention is constructed as described above, in which a sleeve is rotatably attached via a bearing to a frame that holds a processing tank, one end of the sleeve faces the processing tank, and a shaft sealing member such as a mechanical seal is installed around the outer periphery. insert the drive shaft into the sleeve, attach a pulley to the tip of the drive shaft protruding from the sleeve,
Since the drive shaft and sleeve are removably fixed so that they rotate together, when repairing or replacing the bearing or shaft sealing member, the fixed portion of the drive shaft and sleeve must be removed and the sleeve The bearing and shaft sealing member can be repaired or replaced by simply removing them from the frame, which greatly simplifies the work and saves labor.
