Description

The present invention relates to a powder-liquid mixing and dispersing systems, the powder is mixed in a liquid to form a slurry, after dispersing it relates to powder-liquid mixing and dispersing systems that produce preparations by stirring and mixing .

  In order to produce a mixed liquid by stirring and mixing powder and liquid, a vibration stirring apparatus called “stirring mixing apparatus (vibromixer)” is used. Patent Document 1 discloses a stirring and mixing device using vibration stirring. That is, a powder and liquid stirring and mixing device is provided with a casing provided with a flow passage through which a fluid flows, a shaft portion disposed in the casing and connected to a motor, and attached around the shaft portion. An agitator comprising the agitated blades, a powder inlet provided in the casing for introducing powder into the casing, and a liquid inlet provided for inserting liquid into the casing; And a powder introduction tube attached to the powder introduction port, and an introduction body disposed in the powder introduction tube and connected to the motor.

  In general, when a liquid is added to a powder and mixed, when a powder is added to a liquid and mixed, and when a powder and a liquid are simply added and mixed simultaneously, the powder is mixed in the liquid. It is known that secondary agglomerated grains (so-called lumps) are generated, and it is extremely difficult to disperse secondary agglomerates once generated in a liquid. According to the stirring and mixing device using vibration stirring for the phenomenon of secondary aggregation, the powder and the liquid can be stirred uniformly.

  However, in the vicinity of the powder inlet where the powder and the liquid are in contact with each other in the stirring and mixing apparatus, there is a problem that the powder absorbs moisture to cause secondary aggregation and close the powder inlet. Then, the stirring mixing apparatus which suppresses secondary aggregation as shown in patent document 2 was proposed. Here, in the stirring and mixing apparatus, an introduction tube provided with a powder introduction port and a liquid introduction port, and a mixture of powder and liquid connected to the introduction tube and introduced from the introduction tube are pushed out to one end. A casing provided with a flow passage through which a fluid composed of the extruded mixture connected to one end of the extruded pipe and the extruded pipe is circulated; and a shaft portion disposed in the casing and connected to a drive source; A stirring body comprising a stirring blade attached around the shaft portion, a funnel-type powder introduction device is attached to the powder introduction port, and powder is introduced into the powder introduction device. A feeder for conveying is provided, and the feeder is connected to a vibration rotation drive source. As shown in Patent Document 2, it is possible to suppress secondary aggregation by incorporating an introduction tube, an extrusion tube, a feeder, etc. into a stirring and mixing device (vibro mixer) and utilizing it for mixing and dispersing powder and liquid. It became.

  However, it has been clarified that the phenomenon in which secondary agglomerates of powder are generated in this liquid occurs remarkably when the powder is mixed with a high viscosity liquid. Therefore, it has become important to develop an apparatus level in which the powder supplied to the stirring and mixing apparatus or a mixture of the powder and liquid does not adhere to the opening. That is, a powder / liquid mixing device for supplying a high-quality slurry to the stirring / mixing device is proposed instead of as a part of the stirring / mixing device (vibro mixer).

  Patent Document 3 discloses a stirring and mixing apparatus and a raw material stirring and mixing system that can obtain a mixed stirred product that is uniformly dissolved or melted. Here, the raw material introduction device connected to the stirring and mixing device includes a raw material storage unit that stores the raw material therein, a raw material supply path that communicates from the raw material storage unit to the introduction port, and a raw material that is stored in the raw material storage unit. And a pump for pushing out to the raw material supply path. This raw material accommodating part has a raw material supply port, and a raw material is supplied through this raw material supply port. The pump has an impeller disposed inside the raw material container, and a rotary motor as a raw material rotation source is connected to the impeller. Specifically, the rotary motor is connected to the rotating shaft of the impeller, and a scraper is provided around the rotating shaft. Thus, it is described that the impeller rotates in the raw material container and pushes the raw material to the raw material supply path.

  As described above, the so-called “premixing”, which is a pretreatment for mixing the powder and the liquid, is independently performed with respect to the “vibromixing” by the stirring and mixing device (vibromixer). A production method was proposed in which a mixture of liquid and liquid did not adhere to the opening. Furthermore, a production method using a device group related to higher-quality stirring and mixing, such as a mixer that disperses powder and liquid to some extent in “premixing” has been proposed.

  On the other hand, with the increasing demand for stirring and mixing devices (vibro mixers) in the industry, the use of stirring and mixing has been expanded to a wide range such as painting, filling, molding, and reaction, and the types of powder and liquid are also wide. Diversified. And in order to implement | achieve a large amount of processing at low cost, the enlargement of the stirring and mixing apparatus (vibro mixer) itself advanced. As a result, a production method in which the premixed slurry is stored in a tank and batch processing is performed in a blending process in accordance with a production plan has become the mainstream in the stirring and mixing treatment, and has reached today.
