Abstract

PURPOSE:To enhance agitation effect of liquid in a tank by arranging a plurality of stators and rotors in the axial direction of the rotors and connecting the rotors via a connector wherein rotors are mutually acted so that liquid flow is formed through the insides of the rotors by means of rotary movement. CONSTITUTION:In a rotor aggregate wherein two rotors 3, 3 are integrally joined via a connector A, liquid incorporated in a cylindrical joint 5 is discharged through slits 6 by centrifugal force besides shearing and agitation by rotors 3, 3 and the surface of the cylindrical joint 5. Since liquid flow accompanying it is generated through the rotors 3, 3, retention of liquid in the inner diameter parts of the rotors 3, 3 is eliminated and agitation effect is enhanced. Further in the rotor aggregate, rotors 3, 3 are prevented from being slanted and transferred because both reaction force acting on one rotor 3 and reaction force acting on the other rotor 3 are canceled and both rotors are balanced.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to improvements in not only general stirring devices for stirring fluids but also stirring devices for stirring fluids under high pressure and high vacuum conditions. It is.

[Conventional technology]

As shown in Fig. 10, as a conventional stirring device of this type,
The stator (2) constituting the motor is entirely disposed outside the stirring layer (1) made of non-magnetic material, and the cylindrical rotor (
3) By the rotation of this rotor, the liquid in the tank is
It? - devices are known.

The above-mentioned stirring device is a non-seal type in which the power transmission shaft of the motor does not pass through the NIK, and it is not only a general stirring device, but also allows the inside of the stirring tank (1) to be completely shut off from the outside, so it can handle high pressure and high pressure. It is said to be suitable for agitation treatment in the desired state.

[Problem that the invention seeks to solve]

However, in the above stirring device, the cylindrical rotor (3)
The liquid in the inner diameter part rotates with the cylindrical rotor (3),
It is difficult to obtain liquid movement with other parts.

For example, the 11th M and 1st
As shown in Figure 2, there is a stirring tank (1) inside the cylindrical rotor (3).
) It has been proposed that a fixed baffle plate 4 is inserted into the wall so that liquid movement can be obtained. Therefore, the floating rotating cylindrical rotor (3) moves in the opposite direction of the liquid flow due to the reaction force of the liquid flow, and as shown by the dotted line in Figure 11, the stator ( 2)
It deviates from its normal position, resulting in a decrease in rotational thrust.
In addition, by moving the cylindrical rotor (3) in the opposite direction to the liquid flow, the left-right balance of the cylindrical rotor (3) due to the magnetic force of the stator (2) is disturbed, resulting in a stirring tank (1) as shown in Fig. 11.
) The gap (j+) (t, ) in the liquid film thickness of the cylindrical rotor (3) with respect to the bottom surface becomes 1+>11, which causes the cylindrical rotor (3) to tilt and the cylindrical rotor (tt Mt'+ There is a drawback that the end of 3) comes into contact with and slides on the bottom of the stirring tank (1).

Although not shown, a method has also been proposed in which the entire vane plate is attached to a position close to the opening of the cylindrical rotor (3) to move the liquid. The shaped rotor (3) moves as shown in the dotted line in Figure 10,
The same drawbacks as above arise.

[Means for solving the problem] The present invention provides an agitation system in which a stator is disposed on the outside of a non-magnetic agitation slide, a rotor is disposed in a tank, and the liquid in the tank is agitated by the rotation of the rotor. In the device, the stator and the rotor are arranged in multiple numbers in the rotor axis direction, and the rotors are connected to each other via a connecting body that works to generate a liquid flow through the inside of the rotor by rotational movement, This is an attempt to solve the above-mentioned problems.

[For production]

As mentioned above, in a rotor assembly formed by connecting multiple rotors together via a connecting body, the reaction force applied to one rotor and the reaction force applied to the other rotor cancel each other out to maintain balance. , there is no risk of misalignment with the stator. Further, since a liquid flow is generated through the interior of the rotor due to the rotational movement of the connecting body, the effect of stirring the liquid in the tank can be enhanced.

[Embodiments of the invention]

Figures 1 to 4 show an embodiment of the present invention, in which (1) is a stirring tank made of non-magnetic material, and is positioned outside the bottom of the stirring tank (1). The stator is arranged for the required length M' (two stators arranged by k)
, (2), and the rotor in the stirring tank (1) is composed of two rotors (3), (3) arranged in the axial direction so as to face each of the stators (2), (21). , the two rotors (31, (3)) are connected by a coupling body.

The connecting member has a structure in which a large number of slots (61i) are provided on a non-magnetic material part (5) formed to have the same diameter as the rotors (3), (3). fixed by suitable means.

As mentioned above, the two rotors (3), (3) are connected to the connected body (Al
According to the rotor assembly integrally connected through the
In addition to shear agitation by the surfaces of the rotors (31, (3) and the part (510), the liquid in the part (5) is discharged from the slit (6) by centrifugal force as shown in Figure 3, and the accompanying liquid Since the flow is generated through the rotors (3), (3), there is no stagnation of liquid in the inner diameter of the rotor f31 (3).
The stirring effect is increased.

Further, in the rotor assembly, one rotor (3
) and the reaction force received by the other rotor (3) cancel each other out and maintain a balance, so that tilting and movement of the rotor can be prevented.

A knot (6) is bored in the part (5) of the connecting body (2).

The wing plate (9) shown in Fig. 8 is a flat plate, but if it is curved into an arc like the three blade roots (9), (9), (9) in Fig. Since the plates (9), (91, (9)) themselves can have a webbed action, the stirring effect can be further improved.
