Description

[0001] The present invention relates to a speed adjustable stirring and defoaming device,

The present invention relates to an apparatus for rotating and revolving a sample vessel for mixing, stirring and defoaming various powders and liquids in a single apparatus. The apparatus can stably rotate and revolve the sample vessel while independently controlling the revolution speed and the rotation speed of the sample vessel And more particularly, to a stirring and defoaming device configured to be adjustable.

There is known a method and apparatus for stirring and defoaming an object to be processed by stirring the object with the object to be processed in a container by mixing the object to be treated such as liquid or powder and removing the bubbles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a conventional stirring and deaerator will be described in detail with reference to the accompanying drawings.

1 is a schematic view of a conventional stirring and deaerator.

As shown in Fig. 1, the conventional stirring and deaerator 1 includes means for rotating the container 2 and means for revolving, as well as a case in which the container 2 is rotated and revolved, (Hereinafter, simply referred to as " stirring and defoaming ") of a single material and a mixed material accommodated in the container by rotating the container .

1, a conventional stirring and defoaming device 1 includes a plurality of containers 2 capable of receiving various materials to be stirred and defoamed, and a plurality of container holders (not shown) An idling member 12 for revolving the container holder 11; a circular member 13 provided so as to be able to switch between rotation and non-rotation coaxially with the idler member 12; A drive motor 3 for rotating and driving, and a control unit for controlling them.

The container 2 and the revolving member 12 and the circular member 13 supported by the container holder 11 and the container holder 11 are disposed inside the case 20. The container holder 11 has an annular contact portion 11a at its outer periphery and is rotatably fixed to the revolving member 12 through a bearing 34. The contact portion 11a is rotatably supported by the circular member 13 (I.e., the outer peripheral portion of the outer periphery). A friction material is disposed in the contact portion 11a. For example, as the friction material, an O-ring 31 made of a rubber material is used. When the revolution member 13 is switched to the non-rotatable state, when the revolution member 12 revolves, the frictional force between the contact portion 11a of the container holder 11 and the circular member 13 , The container holder 11 rotates. Therefore, the container holder 11 and the container 2 supported by the container holder 11 can rotate and rotate.

However, since the conventional stirring and deaerator having such a configuration can not independently control the revolution speed and the rotation speed of the container 2, diversification of stirring and defoaming operations is limited. It has been proposed to mount a separate belt on the central axis of the container 2 so that the revolution and rotation of the container 2 can be independently controlled. In this case, however, the rotation axis of the container 2 is inclined There is a problem that the belt is frequently detached.

That is, the stirring and deaerator according to the present invention includes a revolving rotary plate 100 arranged in a width direction so as to be horizontally oriented and a hollow tube erected vertically, and an upper end thereof is coupled to a bottom surface of the revolving rotary plate 100 And an eccentric rotation shaft 110 integrally rotating with the revolving rotary plate 100. The one end (upper end in this embodiment) is inserted through the central portion of the revolving rotary shaft 110 and the center portion of the revolving rotary plate 100, A rotary shaft 200 rotatable independently of the revolving shaft 110 and a rotatable shaft rotatable about a rotation axis 200 of the revolving shaft 200, A pair of helical universal joints 400 coupled to the upper ends of the pair of lower rotary shafts 300, and a pair of helical universal joints 400, A pair of upper rotation shafts 500 coupled to the joint 400 and extending in the direction in which the other end intersects the longitudinal direction of the lower rotation shaft 300 (upper left and upper right directions in FIG. 1) And a pair of rotating cups 600 coupled to upper ends of the upper rotating shaft 500 and rotating integrally with the upper rotating shaft 500.

When the revolving rotary plate 100 rotates about the revolving rotary shaft 110, the revolving cup 600 mounted on the revolving rotary plate 100 revolves around the revolving rotary plate 100, The lower rotary shaft 300 that receives the rotational force from the rotary shaft 200 when the rotary shaft 200 rotates is rotated and the helical universal joint 400 and the upper rotary shaft 500 rotate integrally with the lower rotary shaft 300, And the rotating cup 600 are also rotated.

As described above, the stirring and deaerator of the present invention has a structure in which the revolving shaft 110 for revolving the revolving cup 600 and the revolving shaft 200 for rotating the revolving cup 600 are independently rotatable The user can independently control the revolution speed and the rotation speed of the rotary cup 600 and thus the stirring and defoaming process can be performed under various conditions.

In addition, the stirring and deaerator according to the present invention is not arranged so that the rotary cup 600 in which the object to be processed is placed is gathered at the center of rotation of the revolving rotary plate 100, The upper rotation shafts 500 are arranged so as to be interlaced with each other so that each rotary cup 600 is located at a position corresponding to the edge of the revolving rotary plate 100. [ That is, the pair of lower rotary shafts 300 are arranged to be opposed to each other about the rotary rotary shaft 200, and the pair of upper rotary shafts 500 are arranged to be parallel to each other with their ends extending in different directions .

When the pair of rotary cups 600 and the rotary shafts (more specifically, the lower rotary shaft 300 and the helical universal joint 400 and the upper rotary shaft 500 assembly) are arranged to be interlaced with each other, 100) can be greatly reduced, thereby achieving the effect of miniaturization of the stirring and deaerator and reduction of the manufacturing cost.

An upper rotation drive pulley 220 is provided at the upper end of the rotation rotation shaft 200 protruding upward from the upper surface of the revolving rotary plate 100 and a rotary rotation shaft 200 protruded downward from the bottom surface of the idle drive pulley. And a cup rotation pulley 310 connected to the upper rotation drive pulley 220 by a belt is provided at a lower end of the lower shaft housing 130. [ At this time, the upper rotation drive pulley 220 is connected to each cup rotation pulley 310 so as to be able to transmit power by a rotation belt (not shown). Accordingly, when the rotating shaft 200 is rotated by a separate power source, the rotating force of the rotating shaft 200 is transmitted to each cup rotating pulley 310, so that the rotating cups 600 are all rotated.

As described above, the stirring and deaerator of the present invention is configured such that the rotating rotary shaft 200 for rotating the rotary cup 600 is not located below each lower rotary shaft 300 but is positioned on the rotary shaft of the rotary rotary table 100 The rotation of the revolving rotary plate 100 is not changed and the revolving force is transmitted to the revolving cup 600. In other words, So that it can be made more stable.

The revolving structure of the revolving shaft 110 may include a revolving shaft 200 (see FIG. 1) and a revolving shaft 210 (see FIG. 1) ) Rotation structure, detailed description thereof will be omitted.

FIG. 7 is a cross-sectional view showing a structure in which the rotating cup 600 is mounted on the revolving rotary plate 100, and FIG. 8 is an exploded perspective view showing a structure in which the rotating cup 600 is coupled to the upper rotating shaft 500.

The stirring and deaerator according to the present invention is configured such that the lower rotary shaft 300 and the upper rotary shaft 500 for transferring the rotational force of the rotary rotary shaft 200 to each rotary cup 600 rotate on the rotary rotary plate 100 stably A pair of fixed frames 120 which are vertically erected and fixedly coupled to the upper surface of the revolving rotary plate 100 and a pair of fixed frames 120, A pair of lower shaft housings 130 fixed to the pair of fixed frames 120 so as to be rotatable about an axis of rotation of the upper rotary shaft 500, ) Is further provided.

A lower bearing 132 surrounding the lower rotation shaft 300 is provided in the lower shaft housing 130 and an upper bearing 142 surrounding the upper rotation shaft 500 is provided in the upper shaft housing 140. [ The lower rotation shaft 300 and the upper rotation shaft 500 can rotate stably without being swung or tilted to one side in a process of receiving rotation force from the rotation rotation shaft 200. As a result, The pair of spin cups 600 also has the advantage that stable rotation is possible.

In order to effectively mix the object to be processed contained in the rotary cup 600, the rotational freedom of the rotary cup 600 needs to be further diversified so that the rotary cup 600 moves in various patterns. Accordingly, the stirring and deaerator according to the present invention can be configured to repeat the rising and falling of the spinning cup 600, rather than merely revolving and rotating.

That is, the rotating shaft of the rotating cup 600 is coupled to the upper end of the upper rotating shaft 500 so as to be movable in the longitudinal direction of the upper rotating shaft 500, and the upper rotating shaft 500 is inserted to penetrate the central portion A vertical movement cam 710 which is integrally rotated with the upper rotation shaft 500 and is seated at the upper end of the upper shaft housing 140 so as to be slidable in the longitudinal direction of the upper rotation shaft 500, And a guide pin 730 connecting the guide bracket 720 and the rotary cup 600 to each other. Since the lower end of the vertical movement cam 710 and the upper end of the upper shaft housing 140 are formed of a sine wave or a wavy pattern, the vertical movement cam 710 repeatedly ascends and descends when it is rotated along the upper rotation axis 500 The guide bracket 720, the guide pin 730, and the rotating cup 600 connected to the up and down movement cams 710 are repeatedly lifted and lowered.

As described above, when the rotating cup 600 is configured to be lifted up and down while rotating, the object to be processed contained in the rotating cup 600 can be effectively mixed with the sidewalk, thereby improving the stirring and defoaming effect . In addition, since the rotating cup 600 can be lifted and lowered by installing the cam device without any separate driving means, the power saving effect can be obtained.

The guide pin 730 connecting the guide bracket 720 and the rotary cup 600 is to be lifted and lowered integrally with the upper rotary shaft 500. Both ends of the guide pin 730 are simply moved to the rotary cup 600 And the guide bracket 720, the guide pin 730 may be detached laterally due to the centrifugal force. Therefore, the stirring and deaerator according to the present invention can prevent the guide pin 730 from being detached from the rotary cup 600 or the guide bracket 720 and to be stably rotated in unison with the upper rotary shaft 500 . A flange 510 is formed between the guide bracket 720 and the rotary cup 600 in the outer side surface of the upper rotary shaft 500 and the guide pin 730 is coupled to the flange 510 .

When the guide pin 730 is installed so as to pass through the flange 510 of the upper rotary shaft 500, even if a large centrifugal force is generated in the guide pin 730, the guide pin 730 is not detached laterally, So that it is advantageous that the rotating cup 600 can be stably lifted and lowered.

A guide block 740 may be further provided between the flange 510 and the rotating cup 600 so that the rotating cup 600 does not directly hit the upper end of the upper rotating shaft 500 . When the guide block 740 is added as described above, the guide pin 730 should be mounted so as to penetrate the guide block 740.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the invention.
