Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a medium to disperse an object to be processed,
The present invention relates to a medium disperser capable of crushing and mixing.

In the medium disperser, when cooling the heat generated in the processing tank,
It is known that it is more efficient to pass cooling water through a rotating shaft provided inside the processing tank, as compared with cooling with a jacket provided outside the processing tank. In this case, the cooling water flows through the inner surface of the rotating shaft to remove the heat in the tank through the wall surface, but the rotation of the shaft causes the cooling water to fly to the inner surface of the wall and tends to adhere to the wall surface by the action of centrifugal force. , Cooling water having an increased temperature may stay in contact with the wall surface without flowing. Therefore, the exchange of the heated cooling water with the low-temperature cooling water becomes insufficient, and the low-temperature cooling water may be directly drained. Even though the temperature of the drainage is low, the temperature inside the treatment tank is high. Was often said.

The present invention relates to a medium disperser in which a temperature control medium such as cooling water is evenly circulated on the inner surface of a wall of a rotating shaft so that the temperature rise is uniformly distributed in order to improve such drawbacks.

According to the present invention, in order to achieve the above object, an inner pipe through which a temperature control medium flows is inserted into a hollow rotary shaft to form a flow path circulating between the inner pipe and the inner surface of the rotary shaft. There is provided a medium dispersion machine, wherein guide means is formed on the inner surface of the rotating shaft so as to guide the temperature control medium in the axial direction.

In the medium disperser of the present invention, the temperature control medium that is blown to the wall surface of the rotary shaft by the rotation of the rotary shaft is moved in the axial direction by the guide means and does not remain attached to the wall surface but circulates one after another. By exchanging with a new temperature control medium, the temperature inside the tank can be controlled efficiently through the wall surface.

A description will be given below with examples.

The present invention can be applied to various types of dispersers such as a vertical type and a horizontal type, but in the figure, a horizontal type disperser is shown, and the processing tank (1) has a temperature control medium such as cooling water and hot water around it. Has a jacket (2) that circulates, an end plate (4) having an inflow port (3) for an object to be processed is provided at one end, and an outflow port for the processed product at the other end
An end plate (6) communicating with (5) and the drive source is provided. A hollow rotary shaft (7) is provided in the processing tank so as to be rotated by the drive source, and the rotary shaft has a disc shape so as to give a motion to an object to be processed and a medium (not shown). The rotor blades (8) having various shapes such as a rod shape, a protrusion shape and the like are formed. First
In the figure, a disk-shaped rotary blade (8) is fitted to the rotary shaft (7), a ring-shaped spacer (9) is fitted, and after successively fitted, a holding plate (10) is attached to the end. Although it is fixed by screwing, as shown in Fig. 2, the keyway (1
In some cases, 1) and 12) are formed, and a spacer key (14) having steps (13) at both ends is engaged with the key groove to fix the rotary blade to the rotary shaft.

An inner pipe (15) is inserted in the rotary shaft. One end of the inner pipe (15) is connected to a supply pipe (16) that communicates with a supply source of a temperature control medium such as cooling water or hot water, and has an ejection hole (17) at its tip and a rotating end. It is pivotally supported by a support piece (18) provided on the shaft (7). The inner side of the rotary shaft (7) communicates with the discharge pipe (19), and thereby a flow path of the temperature control medium is formed which exits the inner pipe and passes through the inner surface of the rotary shaft. An opening is formed at the tip of the inner pipe (15), and the supply pipe (16) and the discharge pipe (19) are formed.
It is also possible to form a flow path that is discharged from the inner surface of the rotating shaft through the inner pipe by reversing the connection of the above.

A guide means is formed on the inner surface of the rotating shaft (7) so as to guide the temperature control medium in the axial direction. The guide means can be variously constructed, and as shown in FIGS. 1 and 2,
Place the screw (2) so that the tip comes close to the wall of the rotating shaft (7).
0) to the inner tube (15) or the baffle (21) to the rotating shaft.
It can be fixed to the inner surface of (7) (FIG. 3), or a spiral groove (not shown) can be formed on the inner surface of the rotating shaft. In addition,
The turning direction of the screw or the like may be appropriately determined depending on the rotation direction of the rotating shaft and the flow direction of the temperature control medium flow path.

Thus, in order to control the temperature inside the treatment tank, cooling water, warm water or other suitable temperature control medium is supplied from the supply pipe (16) to the inner pipe (15) and ejected from the ejection hole (17). If so, the temperature control medium is the rotating shaft
Heat can be controlled by exchanging heat through the wall of (7).
Then, the temperature control medium such as the cooling water having an increased temperature moves axially along the guide means provided on the inner surface and is discharged from the discharge pipe (19). The temperature inside the tank can be adjusted by moving to the inner surface of the rotating shaft one after another.

The present invention is configured as described above, and the temperature control medium can circulate evenly on the inner surface of the rotating shaft to uniformly control the temperature in the tank.
