Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mixer for mixing, stirring, dispersing, etc., a processing solution in a tank, and more particularly, to a high-speed rotating rotor in the center of the tank and surrounding the rotor. The present invention relates to a turbo mixer which is provided with a stator and allows a processing liquid to flow through a gap between the stators to perform processing.

[0002]

2. Description of the Related Art A mixer having a turbo mechanism, such as a homogenizer and a turbo mixer, has a rotating shaft extending from a frame above the tank into the tank and a rotor attached to a lower end thereof. At the same time, a plurality of rods extending downward along the rotation axis are fixed to a frame around the rotation axis, and a lower end of the rod is arranged so as to surround the rotor.
The rotor is rotated at a high speed so that the processing liquid in the tank is sucked into the rotor part and passes through a gap formed in the stator. When the viscosity of the solution becomes high, only the processing solution around the rotor is sucked in, and the movement of the processing solution in the entire tank, particularly in the outer peripheral portion, becomes insufficient, so that the processing cannot be performed efficiently.

[0003] The above-mentioned phenomenon can be solved by providing another stirring blade or the like so that the processing solution in the outer peripheral portion flows in the tank, but the above-mentioned phenomenon can be solved around the rotation axis of the frame above the tank. Since the rod for holding the stator is provided along the rotation axis, it is difficult to rotate the stirring blades and the like provided on the outside of the rod from the rotation axis side because the rod is an obstacle. there were. On the other hand, if the eccentric stirring blade is provided by removing the center part of the tank, the flow of the processing liquid in the tank becomes asymmetric, which causes vibration and is not preferable.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a turbo-type mixer having a rotor and a stator surrounding the rotor as described above, wherein the viscosity of the processing liquid is high. Even when the processing liquid flows through the entire tank, it is effectively mixed, stirred,
It is an object of the present invention to provide a turbo mixer capable of dispersion and the like.

[0005]

According to the present invention, a rotating cylinder that rotates at a low speed is provided above a tank, a central shaft is inserted inside the rotating cylinder, and a rotor is provided at a lower end of the central shaft. A blade is provided on the rotary cylinder so as to rotate along the inner wall of the tank,
A concentric biaxial turbomixer comprising: a support member formed on the blade in the direction of the rotor; and a stator surrounding the rotor is attached to the support member. The rotor rotates at a high speed in the center of the tank, and the processing solution stirred at a low speed by the blade flows entirely in the tank without staying in a part. Thus, the mixture is sucked into the rotor and the stator, mixed, stirred, dispersed, and the like, thereby achieving the above object.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawing, above a tank (1), there is a center shaft (2) which is rotated at a high speed by a drive source (not shown). It extends downward through the center of the rotating barrel (3) rotated at low speed by the source. At the lower end of the center shaft (2), a rotor (4) constituting a turbo mechanism is provided.

As shown in FIGS. 2 and 3, the rotor (4) has grooves (5), (5),.
And a top paddle blade (7) from which the processing liquid in the tank is fed from above to the rotor body (6). It has a lower paddle blade (8).

The rotary cylinder (3) is provided with a blade (9) which is rotatable along the inner wall of the tank. In the figure, the blade (9) uses a frame-shaped blade, but a spiral ribbon or other appropriate blade can be used.

A support member (10) is provided at an appropriate position of the blade (9), in the drawing, at a vertical frame portion of the blade toward the rotor (4). The support member (10) is
In the figure, it is formed of a rod-like member such as a rod,
It may be composed of a plate-like member or a net-like member. The support member (10) may be attached to a bottom frame portion or an upper frame portion of the blade (9).

The supporting member (10) has the rotor
A stator (11) surrounding (4) is attached. As shown in FIGS. 2 and 3, the stator (11) has a large number of radially spaced chips (14) between the upper plate (12) and the lower plate (13). ) Are provided, and a tubular block piece (16) sandwiched between the upper plate (12) and the lower plate (13) is provided at an appropriate position. Then, the support member (10) and the block piece (16) are fixed with a fixing tool such as a bolt (17). In the drawings, the main holding member is attached to the upper plate side, but may be attached to the lower plate side.

In the above-described embodiment, the rotor and the stator constituting the turbo mechanism have the structure as shown in the figure. However, the rotor and the stator have various other structures depending on the purpose of processing. -A stator and a stator can be used.

In the tank, the center shaft (2) is rotated at a high speed, for example, about 2000 rpm, and the blade (9) is rotated at a low speed, for example, about 20 rpm.
When the processing liquid is rotated at a rotation speed such as pm, even if the processing liquid is a high-viscosity material, the processing liquid flows evenly in the tank, and the above-mentioned rotor (4)
And can pass through the gap of the stator (11) to be sufficiently mixed, stirred, and dispersed.

[0013]

The present invention is constructed as described above, and the center axis for rotating the rotor extends through the rotary cylinder into the tank, and the brake rotates on the rotary cylinder along the inner wall of the tank.
The blade is attached, a support member is formed on the blade in the direction of the rotor, and a stator surrounding the rotor is provided on the support member. By rotating the rotary cylinder at a low speed, the rotor rotates at a high speed at the center of the stator, and can perform mixing, stirring, dispersion, and the like by a turbo mechanism. Since the blade rotates at a low speed along the inner wall of the tank and prevents the processing liquid from staying in the tank, it is possible to efficiently process even a highly viscous material, Since the rotating cylinder rotates concentrically, vibration and the like can be prevented from being generated.
