TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mixing device for mixing a plurality of types of powders, liquids, and the like having different content components, and more particularly to a mixing device capable of easily performing disassembly, assembly, washing, and the like. .
[0002]
[Prior art]
2. Description of the Related Art In a wide range of industrial fields such as chemistry, food, and pharmaceuticals, mixing of a plurality of types of powders and liquids having different components is performed. For example, when a compounding agent such as a stabilizer or a pigment is dispersed and mixed into a resin powder, when an inorganic substance and a resin powder (or a resin powder or a fiber) are dispersed and mixed, when a fat or oil or a fragrance is dispersed and mixed into a flour, a paste is used. A material (mixture) for commercialization is produced by mixing various kinds of powders and liquids or mixing powders and liquids, such as in the case of mixing and kneading fibers or inorganic substances with a resin in a state.
[0003]
Conventionally, for mixing powders and liquids, there has been provided a mixing device in which a predetermined amount of powders, liquids, and the like to be mixed are put into a cylindrical mixing mixer having an open upper surface, and the mixture is stirred by a stirring blade. ing.
FIG. 6 shows an example of a conventional mixing apparatus, in which A is a cylindrical metal mixing container (mixer) having an open upper surface, and B is a stirring drive unit. The mixing vessel A is placed on a horizontally fixed fixing table D via a plurality of supporting rods or supporting plates or a cylindrical supporting member C above the stirring driving section B, and fixing tools E such as bolts and clamps are provided. Are used to fix both.
[0004]
A stirring drive shaft G, which is rotatably provided on the stirring drive unit B via a bearing F, penetrates the fixing table D and the mixing vessel A, reaches the inside of the mixing vessel A, and in the mixing vessel A, the drive shaft G Has a plurality of stirring blades H attached thereto. In addition, the space between the mixing vessel A or the fixed base D and the drive shaft G is sealed by a seal member I.
[0005]
In the above configuration, a predetermined amount of powder, liquid, and the like to be mixed are put into the mixing container A, and the stirring blade H is rotated to mix for a predetermined time. As shown in FIG. 7, a discharge port J is formed in the lower portion of the side surface of the mixing container A, and the discharge port J is normally closed by an on-off valve K. The on-off valve K is connected to a cylinder L, and the discharge port J is opened and closed by horizontally moving the on-off valve K left and right by operating the cylinder L.
[0006]
[Problems to be solved by the invention]
When the stirring and mixing of the materials in the mixing container A are completed as described above, the mixture is transferred to an appropriate container (not shown) through the open outlet J.
However, since the mixture discharging mechanism including the on-off valve K and the cylinder L is fixed to the mixing vessel A, when the mixture remains on the bottom plate of the mixing vessel A, the mixture remains even if the discharge port J is opened. It was not possible to easily remove the material, it took time to discharge, and there was an economic loss due to the residue.
[0007]
Further, when the residue is adhered to the mixing container A after the mixture is discharged, the mixing container A is fixed on the fixing table D. A worker entered the room and scraped off the residue with a scraper and washed with a rag. However, such manual cleaning work requires time, and has a problem in the production process and a problem in the working environment.
[0008]
Although it is possible to disassemble the seal member I and remove the mixing container A from the fixing table D for cleaning, disassembling and assembling the seal member I requires a great deal of labor and time. Moreover, since the mixing container A is made of metal, it cannot be used when the powder or liquid has corrosiveness.
[0009]
The present invention has been made in view of the above-mentioned various problems of the conventional mixing apparatus for powders and liquids, and has a structure in which a discharge mechanism for a mixture can be attached to and detached from a mixing container made of a nonmetallic material, and the mixing container itself can be attached to and detached from the device. Thus, an object of the present invention is to provide a mixing apparatus for powder, liquid, and the like, which can easily perform inspection, disassembly, assembly, cleaning, and the like of a mixing container.
[0010]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the mixing apparatus of the present invention is arranged such that the mixing container 2 and the stirring drive unit 3 are installed vertically symmetrically via the fixing table 6 so that the content components charged into the mixing container 2 are different. In the mixing apparatus for stirring and mixing the powder and liquid by the stirring blade 8, the mixing container 2 is detachable from the fixed base 6 and faces the mixture discharge port 16 formed at the lower side of the mixing container 2. A discharge mechanism 10 having a reciprocally movable discharge valve 12 is detachable.
[0011]
The discharge mechanism 10 is detachable from a fastening member 17 wound around the body of the mixing container 2. Further, the mixing container 2 and the fixing table 6 are detachable by a clamp 21, and the mixing container 2 is made of a nonmetal material such as ceramics or FRP resin. Further, a crushing device can be installed in the mixing container 2.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIGS. 1 and 2 show the entirety of the mixing apparatus of the present invention, in which a cylindrical mixing vessel 2 and a stirring drive unit 3 which can be hermetically sealed by an opening / closing lid 1 are installed vertically symmetrically.
That is, the fixed base 6 is horizontally installed on the base 4 via the support member 5, the mixing container 1 is installed on the fixed base 6, and the stirring drive unit 3 is installed in the base 4, and the stirring is performed. The stirring blade 8 in the mixing vessel 2 is rotated by a drive shaft 7 protruding from the drive unit 3. The stirring blade 8 having a similar shape to the inner peripheral surface of the mixing vessel 2 can be fixed by a bolt 9 fastened to the tip of the drive shaft 7.
[0013]
Rotating the stirring blade 8 by the stirring driving unit 3 to stir and mix the powder, liquid, and the like charged into the mixing container 2 to generate a mixture is the same as in a conventional mixing apparatus.
In the present invention, the mixing container 2 for mixing powders and liquids having different content components is formed of a non-metallic material such as ceramics or FRP resin, and a mixture is formed in a part of the mixing container 2 in a circumferential direction. The discharge mechanism 10 is provided detachably, and the mixing container 2 is detachable from the fixed base 6.
[0014]
As shown in detail in FIG. 3, the discharge mechanism 10 includes a cylindrical discharge portion 11, a discharge valve 12, and a cylinder 13 for reciprocating the discharge valve 12 into the discharge portion 11. The discharge unit 11 and the cylinder 13 are linearly connected via a connecting member 14, and a discharge valve 12 is fixed to a distal end of a cylinder rod 15 passing through the connecting member 14.
[0015]
By installing the tip of the discharge unit 11 so as to face the discharge port 16 formed in the lower part of the side surface of the mixing container 2, the entire discharge mechanism 10 is attached to the mixing container 2. A fastening member 17 such as a metal band is used. That is, as shown in FIGS. 1 and 2, a dividable tightening member 17 is wound around the lower peripheral surface of the body of the mixing container 2, and is fixed by tightening. The tip of the discharge unit 11 is fixed by bolts.
[0016]
For this reason, as shown in FIG. 3, an annular connecting plate 18 is fixed to the fastening member 17 so as to surround the outlet 16, and a bolt (not shown) is used to connect the connecting plate 18 and the end annular plate 19 of the discharging portion 11. It is designed to be fixed using. When the cylinder rod 15 is extended, the discharge valve 12 moves forward so that the discharge port 16 is closed tightly in a normal state.
[0017]
Although the case where the fastening member 17 covers the lower part of the peripheral surface of the body of the mixing container 2 has been described, the present invention is not limited to this. For example, as shown in FIG. You may make it cover with the fastening member 17.
[0018]
As described above, the mixing container 2 and the fixing table 6 are detachable. For this reason, as shown in FIG. 5, the annular projection 20 and the fixing table 6 can be fixed to the lower part of the mixing container 2 using an annular clamp 21. The fixing table 6 and the clamp 21 may be connected at several places by bolts 22, and the mixing container 2 can be attached to and detached from the fixing table 6 by tightening and disassembling the bolts 22.
[0019]
Since the present invention is configured as described above, a powder or a liquid is charged into the mixing container 2 from the charging port 23 formed in the opening / closing lid 1 and the stirring blade 8 is rotated to generate a mixture. After the mixture is generated, the discharge valve 12 is pulled to open the discharge port 16, and the mixture is discharged to an external container through the discharge unit 11 as shown by the arrow in FIG. 3X.
[0020]
When cleaning the inside of the mixing container 2, the discharge mechanism 10 may be detached from the mixing container 2 and the mixing container 2 itself may be detached from the fixed base 6. At this time, the fastening member 17 may be left attached to the mixing container 2. Since the stirring blade 8 is fixed by tightening the bolt 9 to the tip of the drive shaft 7 as described above, when removing the mixing container 2 from the fixing base 6, the bolt 9 is removed and the stirring blade 7 is removed. What is necessary is just to pull out from the drive shaft 7.
[0021]
When the powder and the liquid are stirred and mixed, lumps may be formed depending on the content components. In such a case, the stirring blade 8 cannot break or crush the lump. Assuming such a phenomenon, the mixing vessel 2 may be provided with a crusher (chopper). FIG. 6 shows an example of the crusher, in which a rotating shaft 25 is supported by a bearing 24 installed so as to penetrate the mixing vessel 2 and the fastening member 17. The rotating shaft 25 is connected to a driving motor 26 through a bearing 24, and the rotating shaft 25 protruding into the mixing vessel 2 is provided with a plurality of plate-shaped crushing blades 27. When the crushing blade 27 is rotated by the motor 26, the end face of the plate body facing in the rotation direction crushes the lump into powder. Since the bearing 24 has the shaft seal portion, the powder, liquid and the like do not leak to the outside.
[0022]
In the above-described crushing apparatus, the rotating shaft 25 and the motor 26 are directly connected, but the present invention is not limited to this. For example, as shown in FIG. 7, a rotating shaft 25 and a motor 26 may be used to rotate the crushing blade 27 using a rotation transmission mechanism 28 such as a belt. In this case, the motor 26 may be installed on the base 4 as shown.
In addition, it is possible to arbitrarily select where in the mixing vessel 2 the crushing device is to be installed and how many crushing devices are to be installed.
[0023]
【The invention's effect】
According to the present invention described above, the discharge mechanism 10 can be attached to and detached from the mixing container 2. Therefore, if the discharge mechanism 10 cannot be discharged and remains in the mixing container 2, the discharge mechanism 10 is set in the mixing container 2. It may be removed from the mixing vessel and the residue may be taken out. Since the connecting plate 18 of the fastening member 17 and the annular plate 19 of the discharge portion 11 are fixed using bolts, removal and attachment can be easily performed. In addition, the inside can be inspected through the discharge port 16 after the discharge mechanism 10 is removed.
[0024]
The mixing container 2 is made of ceramics or FRP resin, and is most suitable for mixing, for example, powder or liquid having corrosion. In addition, since the body of the mixing vessel 2 is wound around with the fastening member 17 and the discharge mechanism 10 is attached, it is not necessary to provide a hole for screwing a bolt into the mixing vessel 2. Moreover, since the mixing container 2 is reinforced by the fastening member 17, there is no possibility of cracking, breakage, etc. due to an external impact.
[0025]
Further, since the mixing vessel 2 is detachable from the fixed base 6, the mixing vessel 2 can be removed from the fixed base 6 by pulling out the stirring blade 8 from the drive shaft 7 and releasing the clamp 21. Can be easily fixed and removed. Then, the mixing container 2 is detached from the fixed base 6 and the internal cleaning operation can be easily performed in a short time.
Furthermore, when the mixture forms a lump, the mixture is pulverized into powder by a crusher, so that the mixture does not become defective.
