Description

  The present invention relates to a stirring deaerator, and more particularly to a stirring deaerator suitable for stirring and defoaming materials.

  2. Description of the Related Art A device that stirs and degass a material by rotating while rotating a storage container in which the material is stored (a revolving and stirring type deaerator) is known (for example, refer to Patent Document 1 and Patent Document 2). .

  In this type of conventional stirring and defoaming apparatus, the main components excluding the rotational drive system in each of the patent documents are formed as shown in FIG. Specifically, a revolving shaft 33 with a revolving body 32 attached to the lower portion is pivotally supported via a revolving bearing unit 34 at the center of a support substrate 31 that is horizontally supported in a housing (not shown). Has been. The revolution body 32 is formed in a table shape or an arm shape. Further, the revolution shaft 33 is often supported in the vertical direction. A rotation bearing unit 35 is mounted at a support position having a radius R from the rotation axis center line L1 of the rotation axis 33, and the rotation axis 38 provided at the lower portion of the container holder 37 that accommodates the storage container 36 is connected to the rotation axis 38.

  However, in the conventional stirring and degassing apparatus, the position where the storage container 36 is rotatably supported by the revolving body 32 rotatably supports the rotation shaft 38 provided at the lower portion of the storage container 36. This is a support position for the revolution body 32 of the bearing unit 35 for rotation. Since this support position is located at a radius R from the revolution axis center line L1 of the revolution shaft 33, the conventional stirring and defoaming apparatus has the following disadvantages.

  First, since the rotation support position of the storage container 36 is separated from the revolving axis center line L1 by a considerable distance R in the radial direction, a large centrifugal force acts on the support position during the revolution, Severe operating conditions are generated in which heat is generated by rotating at high speed. Specifically, when a bearing is used in an environment with high centrifugal force, all of the grease filled inside scatters, and as a result, an oil film cannot be formed, resulting in poor lubrication and heat generation. . Therefore, it is necessary to form each component part so that the connected state of each component part of the apparatus can be properly maintained and can function properly under these severe operating conditions. In order to solve the necessity, it is necessary to increase the rigidity such as increasing the rigidity of each component of the apparatus, and it is necessary to cool the heat generating portion, which complicates the configuration.

  Secondly, since the rotation support position of the storage container 36 is separated from the revolution axis center line L1 by a considerably long distance R in the radial direction, the entire apparatus becomes large in the radial direction and the occupied space becomes large. In addition, the power consumption required during operation increases as the components become more robust and heavier, resulting in higher costs.

  The present invention has been made in view of these points, has a simple configuration, is compact, can greatly reduce operating conditions, can reduce the strength conditions of each component, and can be consumed during operation. An object of the present invention is to provide a stirring and defoaming apparatus that can reduce electric power, reduce costs, and reliably perform stirring and defoaming of materials.

  Hereinafter, an embodiment of a stirring and defoaming apparatus according to the present invention will be described with reference to FIGS. 1 to 3.

  As shown in FIGS. 1 and 2, the stirring and defoaming device 1 of the present embodiment has a support box 3 supported horizontally via a vibration-proof spring 4 on a base 2 that forms the bottom of a housing. . At the center of the support box 3, a rectangular frame-shaped revolution body 5 is supported between the bottom plate 3a and the top plate 3b so that the revolution axis center line L1 is vertically arranged and freely revolved. The lower part of the revolution body 5 is an output of a revolution drive motor 7 that forms a revolution drive mechanism in which a revolution shaft 6 projecting from the lower frame surface 5a of the revolution body 5 along the revolution axis center line L1 is fixed to the lower surface of the bottom plate 3a. It is supported directly on the shaft. The upper part of the revolution body 5 is provided on the upper frame surface 5b of the revolution body 5 on the center axis 15a of the sun gear 15 for rotation that projects from the lower surface of the top plate 3b along the revolution axis center line L1. It is supported so that it can rotate freely. A storage container support frame 9 is fixed between the left and right side frame surfaces 5c and 5c of the revolution body 5 and inclined by 45 degrees with respect to the revolution axis center line L1. A rotation shaft 10 is rotatably supported by a rotation shaft bearing unit 11 at a position intersecting with the revolution axis center line L 1 of the storage container support frame 9. As a result, the rotation axis 10 and the rotation axis center line L2 are supported so as to intersect with the revolution axis center line L1 at an inclination angle of 45 degrees. A container holder 12 is fixed to a lower portion of the rotation shaft 10, and a storage container 13 is detachably attached in the container holder 12. The container holder 12 is formed to be openable and closable downward in order to take in and out the storage container 13. The storage container 13 is formed to be openable and closable so that the material M can be taken in and out, and the container holder 12 is formed so that the storage container 13 can be stored inside and fixedly held. The portion of the storage box 3 that faces the container holder 12 is formed to be openable and closable so that the storage container 13 can be attached to and detached from the container holder 12. A rotation satellite gear 14 forming a rotation force applying mechanism is fixed to an upper portion of the rotation shaft 10, and the rotation satellite gear 14 meshes with the rotation sun gear 15 in an internal tooth form. As a result, when the revolving satellite gear 14 revolves together with the revolving body 5, the revolving satellite gear 14 is revolved because it is engaged with the revolving sun gear 15 in a fixed state. In the present embodiment, since both gears 14 and 15 mesh with each other in the form of an internal tooth, when the rotation satellite gear 14 revolves in the clockwise direction when viewed vertically downward (hereinafter the same), it rotates in the counterclockwise direction. Thus, with a simple configuration of meshing the two gears 14 and 15, it is possible to easily realize driving in which the revolution direction and the rotation direction of the satellite gear 14 for rotation are opposite. The center shaft 15a of the rotating sun gear 15 is provided with a known electromagnetic clutch capable of switching between a fixed state and a no-load rotation free state, or a known speed-up and rotation direction of the center shaft 15a can be adjusted. A transmission mechanism may be installed. On the side of the revolution body 5 facing the storage container 13, a counterweight 16 is formed so as to be freely close to the revolution axis center line L <b> 1 by a known mechanism. The portion of the storage box 3 that faces the counterweight 16 is formed to be openable and closable so as to adjust the weight.

  Next, the operation of this embodiment will be described.

<Operation preparation work>
First, the position of the counterweight 16 is adjusted according to the mass of the material M to be stirred and removed.

  Subsequently, the storage container 13 is taken out from the container holder 12, the support box 3, and the casing, and the material M is put in and sealed. Next, the sealed storage container 13 is mounted and fixed at a predetermined position in the container holder 12, and the container holder 12, the support box 3, and the casing are closed, and the preparation work is completed.

<Stirring deaeration operation>
When the revolution drive motor 7 of the revolution force imparting mechanism is rotated to cause the revolution body 5 to revolve clockwise around the revolution axis center line L1, the sun gear 15 for rotation and the internal teeth form in the fixed state of the revolution force imparting mechanism. When the rotating satellite gear 14 meshing with each other revolves clockwise, it rotates counterclockwise. As a result, the storage container 13 revolves counterclockwise together with the container holder 12 while revolving clockwise together with the revolution body 5. The material M in the storage container 13 is subjected to a centrifugal force due to revolution, the gas component contained in the material M is defoamed, and is agitated by a synergistic effect of the rotation force due to rotation and the revolution force. Furthermore, in this embodiment, since the revolution direction and rotation direction of the storage container 13 are reverse directions, it stirs with high stirring efficiency.

  Further, when an electromagnetic clutch is provided on the center shaft 15a of the sun gear 15 for rotation and the center shaft 15a and the sun gear 15 for rotation are switched between the fixed state and the free load free state, the rotation state of the storage container 13 is changed to the center. It is possible to operate by switching between revolving rotation simultaneous rotation when the shaft 15a is fixed and revolving rotation when the center shaft 15a is in a no-load rotation free state.

  Further, when the rotation speed and the rotation direction of the center shaft 15a and the rotation sun gear 15 are changed by the speed change mechanism, the rotation speed of the storage container 13 or the rotation direction can be continuously changed without stopping the apparatus. And can be changed. In this case, it is possible to appropriately operate while changing the speed and direction of rotation / revolution of the storage container 13 in accordance with the progress of stirring and defoaming of the material M in the storage container 13.

  Thus, in this embodiment, the material M is properly stirred and degassed.

  According to the stirring and defoaming device 1 of the present embodiment, since the rotation shaft 10 is supported so as to rotate freely so as to intersect the revolution axis center line L1 with respect to the revolution body 5, the rotation shaft 10 and its rotation support position The mounting position of the rotating shaft bearing unit 11 is arranged in the vicinity of the revolution shaft center line L1, the centrifugal force acting on the rotating support position of the rotating shaft 10 is suppressed, and the radial size of the entire apparatus is also reduced. It can be kept small. Due to the small centrifugal force, required operating conditions and design conditions such as rigidity for each component of the apparatus are greatly relaxed.

  Further, the rotation shaft 10 can be supported by the rotation shaft bearing unit 11 at a position intersecting with the rotation axis center line L <b> 1 of the revolution body 5, and the centrifugal force acting on the rotation shaft bearing unit 11 that supports the rotation shaft 10 is applied. This can be minimized, and the above conditions can be greatly relaxed. In the present embodiment, two types of centrifugal force are generated by the container holder 12 containing the revenue container 13 attached to both sides of the rotation axis bearing unit 11 with respect to the rotation axis 10 and the rotation satellite gear 14. However, since it acts synergistically on the inner ring of the rotating shaft bearing unit 11, for example, two rotating shaft bearing units 11 themselves are arranged in parallel in the axial direction or the rotating shaft 10 is mounted so as to withstand the centrifugal force. An auxiliary bearing that supports the rotation shaft 10 at the protruding portion may be added by projecting from the satellite gear 14 for rotation toward the sun gear 15 for rotation.

  Further, since the rotation shaft 10 is inclined with respect to the revolution axis center line L1 and the storage container 13 is formed so as to be attachable to the lower side of the rotation axis 10, it is separated from the revolution axis center line L1 in the radial direction. Since the storage container 13 can be held to revolve and rotate freely at the position, the material M in the storage container 13 can be reliably stirred and defoamed.

  Further, the rotation force applying mechanism can be formed by a rotation satellite gear 14 fixed to the upper side of the rotation shaft 10 and a rotation sun gear 15 provided on the revolution axis center line L1 meshing therewith. The storage container 14 can be rotated by a simple configuration.

  As described above, the stirring and defoaming apparatus 1 of the present embodiment has a simple configuration, becomes compact, the operating conditions are greatly relaxed, the strength conditions of each component are relaxed, and power consumption during operation can be reduced. The cost is also low, and the material can be reliably stirred and defoamed.

  In addition, this invention is not limited to the said embodiment, It can change as needed.

  For example, in order to make the radial position of the material M from the revolution axis center line L1 during the stirring and defoaming operation the same as the radial position in the existing stirring and defoaming measure, the protruding length of the rotating shaft 10 from the rotating shaft bearing unit 11 The holding position of the storage container 13 by the sheath holder 12 may be adjusted. Accordingly, effective stirring and defoaming can be performed using the existing stirring and defoaming conditions for the material M.

  Moreover, in order to attach a long syringe-shaped storage container, you may form the center part of the rotating shaft 10 or the satellite gear 14 for rotation in a hollow shape.
