Description

  The present invention relates to a mixing device for precisely mixing various types of powders and powders, or various types of powders and liquids, and more specifically, provided in a cylindrical mixing container so as to be rotationally driven. In the mixing device consisting of the rotating blade portion and the chopper portion, a mixing device with high mixing accuracy is realized by improving dispersion and shearing action, and the mixing device has a structure excellent in disassembly and cleaning properties. It is an object of the present invention to provide a mixing apparatus with good disassembly and cleaning workability that can completely prevent cross-contamination in the disassembly and cleaning work after the lot mixing process.

  As a mixing device provided with a rotating blade and a chopper in a cylindrical mixing container to obtain a necessary mixing action and to obtain a dispersion and shearing action, a conventional Japanese Patent Application Laid-Open No. 03-118827 (hereinafter referred to as Patent Document 1). And Japanese Patent No. 3659915 (hereinafter referred to as Patent Document 2) are known.

  The invention of Patent Document 1 discloses a conventional two-way trough-type container having inner and outer ribbon blades attached to a blade cylinder shaft so that inner and outer ribbons whose twist directions are opposite to each other are subject to the left and right sides of the center. The present invention relates to a heavy ribbon mixer.

  A chopper that is rotatably mounted in a state orthogonal to the blade cylinder shaft is connected to the rotation shaft in the blade cylinder shaft via a gear transmission mechanism, and the inner and outer ribbon blades and the chopper are individually rotated. Therefore, by rotating the inner and outer ribbon blades at a low speed and rotating the chopper at a high speed, it is extremely effective for mixing accuracy by preventing agglomeration of powder that has strong absorbency and tends to agglomerate and particles in the mixing container, increasing the stirring effect, It can be said that the mixing time can be shortened and it has an outstanding effect such as being efficient.

  Further, the invention of Patent Document 2 includes first and second flights (screw blades) attached to a rotating shaft that is rotatably provided in a cylindrical mixing container, and a wall of the cylindrical mixing container. The chopper is provided so as to face the inside from the section and is driven to rotate at a relatively higher speed than the rotating shaft, and the second flight has a predetermined interval in the axial direction from the first flight. The first and second flights are arranged so that a dispersion / shearing position is secured, and the outer peripheral portions of the first and second flights are driven close to the inner wall of the cylindrical mixing container. And the first and second flights are twisted in opposite directions so as to transfer the workpiece to the dispersion / shear position, and the chopper is Dispersion / shear position during the second flight It relates mixing device disposed.

  Thus, Patent Document 2 has the above-described configuration, so that a large amount of the mixture is transferred to the chopper substantially continuously and is subjected to strong dispersion / shearing action by the chopper and mixed uniformly in a short time. Effects can be obtained.

  In addition, since the first and second flights (screw blades) are twisted in opposite directions, the objects to be transferred in these flights collide with each other at the dispersion / shear position. It is said that mixing of workpieces is promoted.

  Thus, the inventions of Patent Documents 1 and 2 above are mixing devices of a type in which rotating blades and choppers are arranged in a cylindrical mixing container, and have been evaluated as mixing devices with improved mixing accuracy of the mixture. ing.

  However, the invention of Patent Document 1 is a ribbon mixer in which a trough-type container is provided with inner and outer ribbon blades attached to a blade cylinder shaft so that inner and outer ribbons whose twist directions are opposite to each other are opposite to each other with respect to the center. In this embodiment, a chopper mounted rotatably in a state orthogonal to the blade cylinder shaft is connected to a rotation shaft in the blade cylinder shaft via a gear transmission mechanism, and the inner and outer ribbon blades and the chopper are individually rotated. Therefore, the constituent parts of the inner and outer ribbon blades and the chopper are particularly complicated, and the disassembly and cleaning properties are extremely poor in these parts.

  In the invention of Patent Document 1, when cleaning the cylindrical mixing container, each set screw is screwed off to separate the central blade cylinder shaft portion and the left and right blade cylinder shaft portions, and the left and right rotation shaft portions and the central rotation shaft. There is also a description that the inner and outer ribbon blade assembly with chopper can be easily removed from the container and is convenient for cleaning by separating the parts from each other. It is a common practice to provide a mouth and to inspect and clean the inside from the inspection mouth.

  Therefore, the size of the inspection port has a limit that affects the structural strength of the cylindrical mixing container, and it is difficult to clean the inside of the cylindrical mixing container, the ribbon blade, and the chopper. There is a problem in terms of safety because a person puts his / her body in the mixed container for cleaning.

  Next, the invention of Patent Document 2 includes the first and second flights attached to a rotary shaft that is rotatably provided in the cylindrical mixing container, and the wall from the cylindrical mixing container. It is composed of a chopper that is provided so as to face the rotary shaft and is driven to rotate at a relatively high speed than the rotating shaft, and the structure is relatively simplified. As in the first aspect of the invention, it is common practice to inspect and clean the inside from the inspection port.

  Moreover, cleaning in the cylindrical mixing container in the invention of Patent Document 2 is performed by removing screw blades (first and second flights) and a rotating shaft provided with the screw blades by removing a side cover of the cylindrical mixing container. It is carried out by pulling out of the container and holding it, and cleaning the inner side of the mixing container, or cleaning the inner side of the screw blade, the rotating shaft, and the side cover.

  However, in the invention of Patent Document 2, the screw blade and the rotary shaft provided with the screw blade are pulled out from one side of the mixing vessel by holding the side cover of the cylindrical mixing vessel and held, and the inner side of the mixing vessel is When trying to clean, the chopper provided at the center of the cylindrical mixing container gets in the way, and it is necessary to first pull out the chopper from the cylindrical mixing container. The screw blades, rotating shaft, and side cover must be removed from the mixing container body so that there is no runout, and moved horizontally to the outside of the cylindrical mixing container.

The holding carriage for holding the screw blade, the rotating shaft, the side cover, and the driving motor for the rotating shaft is held in a cantilever structure to pull out the screw blade, the rotating shaft, and the side cover from one side. The holding carriage has a drawback that it has a very heavy and strong structure.
