Description

  The present invention relates to a paddle for an apparatus that rotates a container and mixes a mixed object in the container.

  Conventionally, in such a paddle for a container rotating type mixing apparatus, as shown in FIG. 7, the container is integrally formed at the tip of the arm part b and the arm part b disposed outside the container a as shown in FIG. a paddle portion c disposed in a, and the paddle portion c includes a horizontal portion d, vertical portions e and e ′ projecting upward from both ends of the horizontal portion d, and a center of the horizontal portion d. And a connecting shaft portion f to the arm portion b protruding upward, and rubber wipers g, h, h ′ are provided on the lower surface of the horizontal portion d and the outer surfaces of the vertical portions e, e ′. The paddle part c is accommodated in the container a installed on the turntable t and the mixing object w in the container a can be kneaded by the paddle part c by rotating the container a by the turntable t. (See, for example, Patent Document 1).

  However, in the above-described conventional chevron-shaped paddle, when the mixing object w is a highly viscous fluid, a ring-shaped region s (indicated by cross-hatching in FIG. 7) inward and above the upper ends of the vertical portions e and e ′. Therefore, there is a problem that must be solved, for example, the high-viscosity fluid cannot be uniformly kneaded due to the occurrence of the non-flow region.

  The present invention is based on the above-described prior art, and in view of the problem that a mountain-shaped paddle cannot uniformly knead high-viscosity fluid, the container is formed integrally with the arm portion disposed outside the container and the tip of the arm portion. A paddle portion disposed within the horizontal portion, a horizontal portion, a vertical portion projecting upward from both ends of the horizontal portion, and a connection to the arm portion projecting upward from the center of the horizontal portion And by providing an inward protruding portion at the upper end of at least one of the vertical portions, the object to be mixed in the region corresponding to the non-flow region can be mixed at the inward protruding portion. Solve the above problems.

In short, the present invention includes an arm portion disposed outside the container, and a paddle portion disposed in the container integrally formed at the tip of the arm portion, the paddle portion including a horizontal portion, A vertical portion protruding upward from both ends of the horizontal portion; and a connecting shaft portion protruding upward from the center of the horizontal portion to the arm portion; and an inward protruding portion at an upper end of at least one of the vertical portions Since the mixed object in the region corresponding to the non-flow region can be mixed with the mixed object in the other region by the inwardly projecting portion, the mixed object in the container is uniformly mixed. I can do it.
Since one of the vertical parts is raised and the inward projecting portion is provided on the other of the vertical parts, the object to be mixed above the other vertical part can be mixed in one vertical part. It is possible to further uniformly mix the objects to be mixed.

Since the connecting shaft portion is a columnar body having a wide width and formed a double-edged edge portion on both sides,
The mixing object flowing in the container is divided at one edge portion of the connecting shaft portion, flows along the front and back surfaces of the connecting shaft portion, and merges through the other edge portion, so that it is downstream from the other edge portion. Since no groove is generated at the confluence portion of the mixed object on the side, mixing of bubbles into the mixed object can be prevented.

  The arm part and paddle part are integrally molded with plastic, so it is possible to reduce the weight and damage the inner surface of the container without providing rubber wipers on the lower surface of the horizontal part and the outer surface of the vertical part. The practical effect such as being able to avoid giving it is great.

It is a front view of the paddle for container rotation type mixing devices concerning the present invention. It is an enlarged view of the XX cross section of FIG. It is an enlarged view of the YY cross section of FIG. It is a top view of the container rotation type mixing apparatus which attached the paddle of FIG. It is a partial cross section front view of the container rotation type mixing apparatus of FIG. It is a horizontal sectional view in the use state of the container in which the paddle was stored. It is a partial cross section front view of the conventional container rotation type mixing apparatus.

  The paddle for a container rotation type mixing apparatus according to the present invention has an arm part 1 disposed outside the container A, and a paddle part 2 disposed in the container A integrally formed at the tip of the arm part 1. The paddle part 2 includes a horizontal part 3, vertical parts 4 and 5 protruding upward from both ends of the horizontal part 3, and a connecting shaft part 6 to the arm part 1 protruding upward from the center of the horizontal part 3. And an inward projecting portion 7 is provided at the upper end of at least one of the vertical portions 4 and 5.

  Specifically, the paddle for the container rotating type mixing apparatus is an integrally formed product made of plastic, preferably made of fiber reinforced plastic to which fibers such as glass fiber are added. As shown in FIGS. 1 and a paddle part 2, and an inward projecting part 7 is formed in the other vertical part 5.

  The arm portion 1 has a substantially inverted L shape with a horizontal portion 9 projecting from the upper end of the column portion 8, and a lower portion of the column portion 8 is an insertion portion 10 having a round bar shape.

The paddle portion 2 has one vertical portion 4 higher than the other vertical portion 5, the connecting shaft portion 6 is wide, and is a columnar body having double-edged edge portions 11 and 11a formed on both sides. Is a columnar body having a flat hexagonal horizontal cross-sectional shape, and has R surfaces chamfered at four corners other than the edge portions 11 and 11a.
The lower surface of the horizontal portion 3 and the outer surfaces of the vertical portions 4 and 5 are convex curved surfaces 12, 13, and 14, respectively.

  In addition, although the thickness of the site | part by the side of the other perpendicular | vertical part 5 in the horizontal part 3 is thinner than the site | part by the side of one perpendicular | vertical part 4 in drawing, the same thickness may be sufficient.

  4 and 5, the insertion portion 10 of the arm portion 1 is inserted into the insertion hole H in the mixing device M, and the paddle portion 2 is accommodated in the container A installed on the turntable T. By rotating the container A by the table T, as shown in FIG. 6, the paddle part 2 is pushed by the mixing object W and moves until the paddle part 2 hits the container A to mix the mixing object W in this state. 2, the mixing target W (for example, a sealing material) that is a highly viscous fluid in the container A is mixed, but the non-flow region of the mixing target W is eliminated by the inward projecting portion 7, and the mixing target W is uniform. To be mixed.

  Further, by making the paddle for the container rotating type mixing apparatus according to the present invention made of plastic, even if the paddle portion 2 hits the container A, the container A is not damaged, the lower surface of the horizontal part 3, the vertical part 4, By making the outer surface of 5 convex surfaces 12, 13, and 14, the frictional resistance against the inner surface of the container A is reduced.
