Description

  The present invention relates to a rotating body for stirring and a stirring device that can be efficiently stirred by generating convection of a fluid by being attached to a rotating shaft of an electric motor or the like and rotating in liquid or gas.

  Conventionally, various rotating bodies for stirring that can be attached to a rotating shaft of a motor such as a handy type electric drill and stir liquid in a container such as a bucket are used. For example, a stirring blade for a high-viscosity solution that can efficiently stir and mix a high-viscosity solution when stirring and dissolving a high-viscosity solution such as a paste, an adhesive, or a paint has been proposed (for example, , See Patent Document 1).

  In addition, a stirring rotator has also been proposed in which fragments and shavings are less likely to occur when hitting a container or the like during rotation (see, for example, Patent Document 2). This rotating body has a right angle after the flow passage connecting the suction port provided near the rotation axis and the discharge port provided on the outermost peripheral portion of the rotation body goes straight along the rotation axis direction from the suction port. It is formed in such a manner that it bends and goes straight toward the outside in the radial direction of the rotating body to reach the discharge port.

For this reason, when the rotating body for stirring is immersed in the liquid and rotated, the liquid that has entered the flow path also rotates together with the rotating body. Thus, the centrifugal force acts on the fluid in the flow passage, the fluid in the flow path by flowing radially outward of the rotating body, to stir the solution causing fluid flow around the rotating body Is.

  However, since the above-described rotating body has a flow passage formed in the solid rotating body, the liquid flow is generated by the centrifugal force of the liquid in the flow passage extending in the radial direction of the rotating body. Therefore, it cannot be denied that the generated flow has a size corresponding to the volume of the flow path, and is not suitable for large volume stirring. In particular, a large rotating body having a diameter exceeding 1 m is heavy and unsuitable for driving. In addition, since it is manufactured by a process including an operation of drilling a suction port and a discharge port in a solid rotating body, it is not suitable for mass production.

It is explanatory drawing which shows the structure of another Example of the rotary body for stirring of this invention, a figure is a front view, b figure is a top view, and c figure is a bottom view.

  In the present invention, a hollow main body that rotates around the axis, a suction port provided in the vicinity of the rotation axis of the main unit, and one or more discharge ports provided on the outermost peripheral surface of the main unit A communication chamber formed in communication between the suction port and the discharge port, and a partition plate that divides the communication chamber into individual regions corresponding to the one or more discharge ports. As a result, mass production is easy, and liquid or gas in a large and large-capacity container can be efficiently stirred.

  That is, the main body of the present invention itself is immersed in the liquid to be stirred and rotates around the axis. By partitioning the communication chamber formed in the hollow main body portion into individual regions corresponding to one or more discharge ports, the liquid or gas inside the main body rotates with the rotation of the main body portion by the partition plate. . Since the centrifugal force acts on the liquid or gas due to the rotation, the liquid or gas flows out from the discharge port provided on the outermost peripheral surface. Depending on the liquid or gas that has flowed out, the liquid or gas flows into the main body from the suction port. In particular, since it is a hollow main body, it is possible to hold a large amount of liquid or gas inside the main body, and the centrifugal force due to the rotation of the main body acts well on the liquid or gas, thereby efficiently stirring. Is possible. Further, since it is a hollow main body, it can be produced by a press or the like, mass production is easy, and a large and large capacity rotating body can be obtained.

  The stirring rotating body of the present invention is attached to a rotation drive shaft of a motor, and the surrounding stirring object around which the rotating body is immersed is obtained by immersing the rotating body in a liquid or gas to be stirred and rotating it around the rotation axis. It produces a flow that stirs a liquid or gas. The diameter of the rotating body can be selected from several centimeters that can stir the liquid to be stirred in a bucket of several tens of liters to ones that can stir the liquid to be stirred in a tank of several tens of tons. It is. The main body portion of the rotating body for stirring has advantages such as smooth rotation as long as the cross section orthogonal to the rotation axis has a circular outer shape.

  For example, in the case of a small rotating body, it is attached to a rotating drive shaft of a motor such as a handy type electric drill, and the rotating body is inserted into a container such as a bucket and rotated around the rotating axis, thereby allowing liquid or gas in the container to be rotated. To produce a flow of stirring. For agitation in large agitation tanks such as sewage treatment plants, a rotating body is attached to the drive shaft of the prime mover located at the top of the agitation tank, and the inside of the tank is agitated by rotating it while immersed. To produce a flow of

  The main body of the present invention may be a hollow body that rotates around the rotation axis, and there are no restrictions on the constituent materials and the like. However, when it hits against the wall surface or the like of the container that holds the liquid or gas during rotation as described above, it needs to be strong enough not to be chipped or damaged. Further, it is needless to say that the partition plate is required to have a strength that is not chipped or broken against an inadvertent impact.

  The communication chamber of the present invention refers to a space in which both the suction port and the discharge port are opened. The suction port of the present invention may be provided in the vicinity of the rotation axis of the main body, and more preferably provided so as to surround the rotation axis symmetrically with respect to the axis. The same number of suction ports may be provided corresponding to one or more discharge ports, or one suction port may be introduced into an area formed by individual partition plates with a hollow main body.

  The discharge port of this invention should just be provided in the outermost peripheral surface of one or more main-body parts. As a matter of course, in order to obtain a uniform and effective stirring state, it is important that the discharge port is arranged symmetrically with respect to the rotation axis. Therefore, preferably, if two discharge ports are provided, it is arranged at a position facing 180 ° with respect to the rotation axis, and if three discharge ports are provided, 120 ° with respect to the rotation axis. Arranged at intervals. The same applies to four or more outlets.

  The hollow main body part and the partition plate may rotate integrally with a rotation shaft passing through the shaft center to generate a swirling flow, and may be integrated with the rotation shaft passing through the shaft center. Thus, the hollow main body may be attached to the rotating shaft and the partition plate via bearing means with respect to the rotating partition plate so that it is difficult to transmit the rotation of the rotating shaft to the main body.

  As the bearing means, a plain bearing or the like, a rolling bearing such as a ball bearing of a ball bearing or a roller bearing of a roller bearing, or the like can be used. In addition, since the rotary body itself is immersed in the liquid to be stirred as a constituent member of the stirring device, a bearing means with improved waterproof sealing is preferable.

  When it is difficult to transmit the rotation of the rotating shaft to the main body, it is possible to rotate in the direction opposite to the rotating direction of the rotating shaft by providing a liquid flow changing means for changing the direction of the discharge flow at the discharge port of the main body. It is possible to rotate in the forward direction, and further to discharge the liquid flow in the vertical direction with respect to the plane of rotation. The optimum discharge flow depends on the liquid or gas to be stirred and the form of the container constituting the stirring device. It is possible to select the direction.

  The partition plate of the present invention only needs to be partitioned into individual regions corresponding to one or more discharge ports, and individual communication chambers formed in the hollow main body by these partition plates correspond to the discharge ports. What is necessary is just to be able to rotate the liquid or gas inside a main body with rotation of a main-body part with a partition plate, and to generate the centrifugal force to a fluid by partitioning by an area | region. The partition plate does not need to be formed so as to cover the entire discharge port cross section. Preferably, it may be formed so as to cover a part or the entire region of the discharge port cross section.

  That is, it is sufficient that a swirling flow of liquid or gas accompanying rotation is generated inside the hollow main body, and the main body of the rotating body having a circular outer shape perpendicular to the rotation axis is the most formed with a discharge port. The region expands as it approaches the outer peripheral surface. Therefore, it becomes possible to stir efficiently because the centrifugal force due to the rotation of the main body part favorably acts on the liquid or gas.

  The partition plate of the present invention may be formed radially with respect to the rotation axis or may be formed in a curved shape based on the rotation axis. Further, the communication chamber may not be completely isolated by the partition plate. In other words, it is sufficient that the partition plate rotates around the rotation axis to generate a swirling flow of liquid or gas inside the main body. Even if the partition plate does not completely isolate individual regions, the swirling flow can be generated. Occur.

  As an object to be agitated according to the present invention, not only a liquid but also a gas generates a swirling flow, which is discharged from a discharge port by a centrifugal force and agitated. As a liquid, not only a solution but also a suspension in which solid particles are dispersed in a liquid, a swirling flow is generated and discharged from a discharge port by a centrifugal force and stirred. For this suspension, a slurry liquid in which the amount of solid particles is larger than that of a liquid, or a dilatant fluid that produces a dilatancy phenomenon that behaves like a liquid in a small shear stress but behaves like a solid in a large shear stress. Even so, it has characteristics that can be performed with a small rotational force.
