Description

[Detailed description of the invention] [Industrial application field] This invention relates to a mixer for stirring, dispersing and emulsifying cosmetics, pharmaceuticals, foodstuffs, chemical products, etc., especially when heat treatment is involved.

[Conventional technology]

As a stirring device that requires this type of heat treatment,
It is already well known that the stirring vessel is a double-walled vessel and the stirring process is carried out while circulating steam, cold water, etc. inside the jacket.

[Problem that the invention attempts to solve]

The conventional cylindrical jacket container mentioned above is
Regarding the heat distribution inside the container, the desired heat treatment effect can be obtained in the area close to the double wall, but the heat treatment effect is low in the center of the container, and furthermore, the stirring member inserted into the container is only rotated at a predetermined position. Therefore, it was not possible to obtain a stirring effect due to uniform heat treatment throughout the container.

[Means for solving the problems] The present invention eliminates the above-mentioned conventional disadvantages and achieves uniform stirring and mixing by making the heat distribution in the processing container uniform and by rotating the stirring member in the container. This is a cylindrical processing container whose top opening is closed with a lid case, with a double-walled jacket-type container wall, and a tubular part with a closed top that communicates with the bottom jacket in the center of the container. An annular processing chamber is formed in the container, a heat medium is circulated and supplied into the jacket and the central tubular part, and a stirring member installed on a rotating shaft inserted through the lid case and projected into the container is rotated along the annular processing chamber. It is characterized by having

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

In the drawings, reference numeral 1 denotes a cylindrical stirring vessel whose peripheral and bottom walls are formed into a double-walled jacket 2, and in the center of the vessel there is a tubular part of an appropriate height that communicates with the bottom jacket 2 and closes the upper part. 3, an annular processing chamber 4 centered around the tubular part 3 is formed in the vessel, and a processing liquid outlet 5 with an opening/closing lid is provided at the bottom.
The jacket 3 is provided with supply/discharge ports 6, 7 for a heat medium of steam or cold water at appropriate locations, and a heat medium introduction pipe 8 is also provided in the central tubular portion 3 with its upper end opening at the upper portion of the tube.

The upper opening of the container 1 is always closed by a lid housing 9 that is opened and closed by a fluid cylinder mechanism 10.
A rotary shaft cylinder 15 that rotates from a motor 12 installed on a frame 11 integrated with the motor 12 through bevel gears 13 and 14 is thrust into the container 1, and a stirring member 17 is attached to a rotating frame 16 formed integrally with the motor 12. These were made to revolve within the annular processing chamber 4 of the container 1.

In the illustrated embodiment, stirring members 17 having different functions such as a rotating paddle 17a, stirring blades 17b, and a scraper 17c are used, and a scraper 1 fixed to the inner periphery of the container 1 and the outer periphery of the central tubular body 3 is used.
7d is shown, but the parts and model used are arbitrary.

In the illustrated example, the stirring members 17a and 17b are rotated at the same time as they revolve in the annular processing chamber 4, thereby further improving the stirring and mixing efficiency. That is, the seat frame 18 is fixed to the frame 11, and its tubular portion surrounds the rotating shaft cylinder 15 and projects into the container 1.
A gear ring 19 is fixed to the lower end of the rotating frame 16.
is used as a gear box to enclose the gear 19, and a gear 20 is attached thereto using the mounting shaft of the stirring rotary paddle 17a as the rotation axis, and by engaging the gear 20 with the gear 19, the rotation of the rotating frame 16 is controlled. The companion gear 19 is used as a great sun gear, and the gear 20 is rotated around it as a planetary gear to cause the paddle 17a to revolve and rotate on its own axis. Provided,
Pulleys 22 and 23 are attached above and below, respectively, and the upper pulley 22 is belt-driven by a motor 24, and the lower pulley 23 is interlocked with a pulley 25 on the axis of the stirring blade 17b, so that the stirring blade 17b rotates on its axis as well as revolves. .

In addition, there is a raw material supply port 2 in the lid casing 11 as shown by the temporary line.
6.Although not shown in the figure, an inspection port, etc. will be provided.

[Effect]

In the above device, raw materials are inputted from the raw material supply port 26, and steam or cold water is circulated within the jacket 2 and central tubular portion 3 of the container 1 to heat or cool the raw materials in the container to an appropriate temperature. 15, the stirring members 17a, 17b, 17
C is revolved in an annular processing chamber 4 centered on the central tubular part, and if necessary, it is also rotated to perform stirring, mixing, dispersion, emulsification, etc. of the raw materials, and after a predetermined processing time, the processing liquid is discharged from the outlet 5. It is for extracting.

[Effect of idea]

According to the present invention, the cylindrical processing container is in the form of a jacket, and the bottom jacket is connected to the center of the container to form a tubular part with the upper end closed, so that the heat medium can also be circulated within the tubular part. Therefore, the periphery of the vessel by the jacket and the center of the vessel are also heated and cooled by the tubular part, making the heat distribution inside the vessel uniform, increasing heat exchange efficiency, and increasing heat transfer through the central tubular part. An annular processing chamber having a large area and high thermal efficiency is formed, and since the stirring member is moved in revolution along the inside of the annular processing chamber, it is possible to obtain uniform and good stirring efficiency within the processing chamber.
