Description

  The present invention relates to a continuous mixer for mixing a fluid mixed material, and more particularly, by changing the cross-sectional shape of the mixed material itself by passing the mixed material through a deformed passage having a changed cross-sectional shape. It relates to the continuous mixer which mixes.

  Conventionally, there are various materials that require mixing. The material is, for example, a material for noodles such as “Udon” and “Soba”, which are used habitually as food, and other materials such as kneaded products, mortar and concrete.

  Materials to be mixed that require mixing often exhibit favorable properties or good properties and physical properties as they are mixed. Therefore, in the case of such materials to be mixed, sufficient mixing work is required in advance. And

  As a device for mixing the material to be mixed, a deformed passage in which the cross-sectional shape of the device gradually changes in the longitudinal direction is provided, and the material to be mixed is passed through the deformed passage by free fall due to the weight of the material to be mixed. Devices for efficiently mixing materials are known.

  For example, as shown in FIG. 17, the element 11 of the device disclosed in Japanese Patent Application Laid-Open No. 10-286449 has an inlet portion I at one end and an outlet portion E at the other end. The element 11 of this device is partitioned by a partition wall 14 that divides the inlet portion I into left and right (in FIG. 17), and the outlet portion E is also partitioned by a partition wall 15 that splits up and down (in FIG. 17). ing. Further, the conventional apparatus is configured by connecting a plurality of the elements 11 vertically. In FIG. 17, the element 11 of the apparatus is configured to be connected via flanges F provided at two inlet portions I and outlet portions E, respectively.

  Then, as shown in FIG. 18, the cross-sectional shapes A and B continuously change from the inlet portion I to the outlet portion E through the intermediate portion, and substantially in the axial direction (when the material to be mixed is allowed to fall freely) A plurality of deformation passages 12 and 13 extending in the vertical direction) are provided. In addition, the wall part 14 of the inlet part I and the wall part 15 of the outlet part E are formed so that the partitioning positions differ by 90 °. Each of these deformation passages 12 and 13 has a merging and dividing function for joining and dividing the materials to be mixed that pass through the respective deformation passages 12 and 13. Then, one or two or more materials to be mixed having fluidity are introduced from the inlet portion I, and mixed by passing through the deformed passages 12 and 13 toward the outlet portion E by free fall.

  The element 11 includes a cylindrical portion, an inlet portion I, an outlet portion E, two deformation passages 12 and 13, partition walls 14 and 15, and the like as an integral structure.

Each element 11 is formed with a rectangular flange F for connecting the inlet portion I and the outlet portion E to each other. The square flange F is formed with a plurality of bolt holes, and the adjacent elements 11 are connected to each other by bolting the end portions using the bolt holes.
Japanese Patent Laid-Open No. 10-286449

By the way, in order to divide the two kinds of materials to be freely dropped into 50:50, the shift angle for shifting the deformation passages 12 and 13 is theoretically 90 °. However, the shift angle of 90 ° is not always appropriate due to the characteristics of the material to be mixed. For example, depending on the nature of the material to be mixed (for example, viscosity) and the difference in flow rate, even if the shift angle is 90 °, the division ratio by each deformation path is not 50:50, for example, 20:80 Thus, there is a problem that the two types do not mix sufficiently effectively.

  However, the conventional device has an integral structure in which the cylinder part, the deformation passage, the partition wall, etc. are shifted and the angle is 90 °, and the angle cannot be adjusted by shifting the partition wall so that the mixing can be performed effectively. It was.

  The present invention has been made to solve such a conventional problem, and it is a technical problem to provide a continuous mixer capable of adjusting the angle by shifting the partition wall so that the mixing can be effectively performed. And

By enabling the adjustment (the angle is larger or smaller than 90 degrees), the versatility that it can be used even when the properties (for example, viscosity) and the flow rate of the material to be mixed are different is enhanced. For example, when the type of material to be mixed varies depending on the production date, it is possible to adjust so as to obtain the optimum mixing efficiency according to those properties. Further, adjustment can be made so that optimum mixing efficiency can be obtained when the flow rate changes.

  In addition, since the powder particles A and B mixed at the point a fall separately in the X direction and the Y direction every time they pass through the lower partition blade 600, the continuous mixer 100 according to the second embodiment. By increasing the number of connections, the mixing can be performed more effectively and uniformly.

[Operation of Embodiment 2]
Next, the operation of the continuous mixer 1 according to the second embodiment will be described with reference to FIGS. Further, similarly to the case of the first element 200 in FIG. 5, a case where two kinds of mixed materials (for example, powder bodies A and B) are introduced from the entrance of the upper casing 2 will be described.

  When the powder A is injected from the material injection port A and the powder B is injected from the material injection port B, the powder A injected from the material injection port A rotates clockwise along the plate members 51 and 53. It falls in the inside where the cross-sectional shape of the internal space changes continuously. Further, the granular material B introduced from the material injection port B falls along the plate members 51 and 52 in the clockwise direction in which the cross-sectional shape of the internal space continuously changes.

Further, adjustment can be made so that optimum mixing efficiency can be obtained when the flow rate changes.

  In addition, since the powder particles A and B mixed at the point a fall separately in the X direction and the Y direction every time they pass through the lower partition blade 6, the continuous mixer that is worn in the first embodiment is used. By increasing the number of connections of 1, the mixing can be performed more effectively and uniformly.

  Furthermore, the continuous mixer 1 which concerns on this Embodiment 2 mixes granular materials, such as dental material, an adhesive agent, cosmetics, foodstuffs, and cement, by adjusting the number and magnitude | size of the continuous mixer 1 which continues. Can be used. Note that the material to be mixed includes fluid materials such as liquid and solid-liquid mixture in addition to powder particles such as powder, sphere, and granule.

It has a remarkable effect that the internal cleaning and maintenance work can be easily performed. In addition, since the upper casing 2 and the intermediate casing 3 and the intermediate casing 3 and the lower casing 4 are connected to each other by a connecting member so as to be freely engaged, the assembly is easier than conventional bolt tightening.

  In the first and second embodiments described above, the case where the ferrule is clamped as the connecting member has been described. However, the connecting member is not limited to the case where the ferrule is clamped. Alternatively, a Victorian joint may be used. That is, as a continuous mixer, the size varies depending on the required mixing capacity, and if it is a very small object (for example, about 5 cm in diameter), it is preferable to clamp the ferrule, In the case of an intermediate level (for example, a diameter of about 10 cm to 15 cm), it is preferable to use a general-purpose Victorian joint. In the case of a larger size, a method in which a flange is attached and a bolt is used is preferable.

The deformation passage includes a first intermediate partition blade that continuously changes a cross-sectional shape of an internal space between the inlet portion and the intermediate portion and rotates in a circumferential direction, and the outlet portion and the intermediate portion. A second partition blade that continuously changes the cross-sectional shape of the internal space between and rotates in the circumferential direction,
The deformation passage formed by the first middle partition blade and the deformation passage formed by the first middle partition blade are formed so that the directions of rotating and passing toward the outlet portion are different,
A continuous mixer in which the inlet portion, the intermediate portion, the outlet portion, the first middle partition blade and the second middle partition blade are formed detachably,
A connecting member for detachably connecting the inlet portion and the intermediate portion, and the intermediate portion and the outlet portion;
This connecting member is capable of adjusting the joining position of the intermediate part and the outlet part in the circumferential direction.
