Description

Inclined Cylindrical Mixer {OBLIQUE CYLINDRICAL MIXER}

The present invention relates to a container-type rotary mixer capable of efficiently mixing two or more kinds of powders, for example, raw materials, such as food, medicine, and chemical products, in a short time. Particularly, in the present invention, the shape is simple and manufactured. An inclined cylindrical rotary container that is easy to provide is provided to provide a container rotary inclined cylindrical mixer with good mixing efficiency.

Background Art Conventionally, a W cone mixer (also referred to as a double cone mixer) has been widely used as a container rotary mixer used for mixing two or more kinds of powders as raw materials for food, medicine, or chemical products.

The conventional W cone mixer includes a gas 50 and mounts 51a and 51b erected from both ends of the gas 50, as shown in FIG. 5, between the mounts 51a and 51b. The rotating shaft 52 is supported by the bearings 56a and 56b so as to be rotatable through the drive device 53, the belt 54, and the pulley 55, and has a cylindrical container body in the center of the rotating shaft 52. The linear motion part 57 which consists of parts, and the two cone-shaped container parts 58a and 58b which spread toward the center part of this linear motion part are joined at both sides, and the closed container which is substantially rhombic in cross section, ie, a mixing container (59) is formed.

And the cylindrical linear motion part 57 which forms the mixing container 59 is the said rotating shaft 52 so that it may cross at right angles with respect to the linear motion part 57 in the state which installed this linear motion part 57 horizontally. Since this is provided, the said mixing container 59 whole is supported by the rotating shaft 52, and is comprised so that rotation is possible. Moreover, the mixed material insertion opening 60 and the mixed material ejection opening 61 are formed in the apex side of the two cone-shaped container parts 58a and 58b which comprise the said mixing container 59, respectively.

In this way, the W cone type mixer inserts two or more types of mixed materials to be mixed through the mixed material insertion hole 60 formed on the apex side of the cone-shaped container portion 58a, and is connected to the rotating shaft 52. The mixing vessel 59 is rotated through the rotating shaft 52 by driving the mixture to mix the mixture material by the positional movement of the mixture material in the mixing vessel 59.

In the W cone mixer, the moving state of the mixed material in the mixing vessel 59 according to the rotation of the mixing vessel 59 is represented by an aggregate (indicated by arrow a) in the cone-shaped container portion 58b, and a cone. Diffusion (shown in arrow b), which occurs by widening from the shape vessel 58a to the cylindrical linear motion portion 57, and is a set (arrow a) and a diffusion of the mixed material repeated by the rotation of the mixing vessel 59. The mixing of materials is performed using the mixing action of arrow b).

Therefore, in the W cone type mixer, the supply of the mixed material which also fills the linear motion portion 57 when the mixed material is inserted may eliminate the diffusion portion of the mixed material and may cause extremely poor mixing efficiency. The supply amount of the standard mixed material of the mixer, that is, the injection rate of the mixed material, was limited to 45% with respect to the capacity of the mixing vessel 59.

Moreover, in the W cone mixer, the rotating shaft 52 is provided in the linear motion part 57 of the mixing container 59, and the rotation of this mixing container 59 rotates around the axis line which passes through the linear motion part 57. In addition, in FIG. Therefore, in the linear motion 57, movement of the mixed material is unlikely to occur in the axial direction of the rotation shaft 52, that is, in the horizontal direction (arrow c), so that the rotation axis 52 is close to the rotation shaft 52. Poor mixing may occur, and this tendency is remarkable especially when the mixed material is supplied beyond the axis line of the rotating shaft 52.

And as an improved type of the above-mentioned W cone type mixer, there exists invention of Unexamined-Japanese-Patent No. 8-155285 (henceforth a patent document 1). The name of the mixer in the invention of Patent Literature 1 is a double cone mixer, which is the same type as the conventional W cone mixer, but the invention refers to the technique of Patent Literature 1, and the mixing vessel is divided into two conical container portions. In the container rotary double-conical mixer, the conical shaft of at least one of the two conical container portions is eccentric from the centerline of the mixing container, without impairing the advantages of the simple structure, the ease of cleaning, and the like. , The mixing speed can be improved.

However, the invention of Patent Literature 1 has a cylindrical linear motion portion as a member of a portion that attaches a rotating shaft and rotates the mixing container in the same way as a conventional W cone type mixer. The moving state of the mixed material in the mixing container according to the rotation of the mixing container is a collection in the conical container portion (cone-shaped container in the conventional apparatus) and a diffusion operation in the cylindrical linear motion portion, and the mixing container is rotated. The mixing of the mixed material is performed by using the set of mixed materials repeated by the above and the mixing action of diffusion.

Therefore, in invention of patent document 1, supply of the mixed material which also fills the said linear motion part at the time of inserting a mixed material removes the diffusion site | part of a mixed material, and may make mixing efficiency extremely bad, and It is considered that the supply amount of the standard mixed material, that is, the injection rate of the mixed material, is about 45% of the capacity of the mixing vessel as in the case of the conventional W cone mixer.

Moreover, in invention of patent document 1, since the rotating shaft is provided in the linear motion part of a mixing container, since the rotation of this mixing container rotates about the axis line passing through a linear motion part, the axial direction of a rotating shaft in a linear motion part That is, the movement of the mixed material is unlikely to occur in the horizontal direction, which may cause mixing defects in the vicinity of the rotation axis of the linear motion unit. This tendency is particularly remarkable when the mixed material is supplied beyond the axis line of the rotation axis. It appears that, if the solution of this point is not achieved, the improvement of the mixing speed and the improvement of the mixing efficiency cannot be expected as in the case of the conventional W cone mixer.

The problem to be solved by the present invention is that it is possible to improve the injection rate of the mixed material even when compared to a mixing vessel of the same capacity, and further, by improving the member shape of the portion for rotating the mixing vessel, thereby rotating shaft in the rotating vessel The present invention relates to a container-type mixer for preventing mixing in the vicinity and efficiently mixing two or more kinds of powders, for example, raw materials for food, medicine, and chemical products, in a short time.

The rotating shaft 3 is provided. The rotating shaft 3 is supported by the bearings 7a and 7b so as to be rotatable through the drive device 4, the belt 5, and the pulley 6, and has an inclined cylindrical eastern portion at the center of the rotating shaft 3. 8) and the two cone-shaped container parts 9a and 9b which spread toward the center part of this eastern part 8 are joined by both sides, and form the hermetically sealed container, ie, the mixing container 10. As shown in FIG.

In the cylindrical eastern part 8 which forms the mixing container 10, the said rotating shaft 3 is provided so that it may cross obliquely with respect to the eastern part 8 in the state which installed this eastern part 8 horizontally. The mixing vessel 10 is supported by the rotating shaft 3 and is rotatably configured, and the mixed material insertion lid is provided on the apex side of the two cone-shaped container portions 9a and 9b constituting the mixing vessel 10, respectively. (11) and the mixed material extraction valve 12 are provided.

In this way, the inclined cylindrical mixer of the present invention inserts two or more kinds of mixed materials to be mixed through the mixed material insertion lid 11 provided on the apex side of the cone-shaped container portion 9a, and is connected to the rotary shaft 3. By driving the apparatus 4, the mixing vessel 10 is rotated through the rotation shaft 3 to mix the mixture materials by moving the mixing material in the mixing vessel 10.

In the present invention, the moving state of the mixed material in the mixing container 10 according to the rotation of the mixing container 10 is set in the cone-shaped container part 9b (arrow a) as shown in FIG. ) And diffusion (arrow b) in the cone-shaped container portion 9a, and the mixing action of the set (arrow a) and the diffusion (arrow b) of the mixed material which is repeated by the rotation of the mixing container 10. The mixing of the materials is carried out using.

Therefore, in the inclined cylindrical mixer of the present invention, two cone-shaped containers 9a and 9b are joined to both sides of the inclined cylindrical eastern part 8 by the shape of the mixing container 10, and this inclined cylindrical shape is formed. Only by the inclination of the eastern part 8, the conical shafts of the two cone-shaped containers 9a and 9b are eccentric from the centerline of the mixing container 10 to form a left and right asymmetric sealed container. The moving distance and the moving speed are different, and as a result, the mixing action of the aggregate and the diffusion is larger than that of the W cone mixer, and all the mixed materials in the mixing container 10 include the left and right positional movements by the rotation of the mixing container 10.

Example 2

FIG. 2 is a front view illustrating Embodiment 2 of the present invention. In FIG. 2, reference numeral 1 denotes a base, and reference numeral 2a denotes a stand which stands up from an end of the base 1, and from this mount 2a, a cantilever shape is rotated. (3) is supported by the bearing (7a) rotatably through the drive device (4), belt (5), pulley (6), the inclined cylindrical shape at the distal end of the rotating shaft (3) protruding in this cantilever shape The eastern part 8 and the two cone-shaped container parts 9a and 9b which spread toward the center part of this eastern part 8 are joined at both sides, and form the hermetically sealed container, ie, the mixing container 10. As shown in FIG.

And the said rotating shaft 3 is installed so that the inclined cylindrical eastern part 8 which forms the mixing container 10 may cross diagonally with respect to the eastern part 8 in the state which installed this eastern part 8 horizontally. The mixing vessel 10 is supported by the rotation shaft 3 in a cantilever shape and is configured to be rotatable. Moreover, the mixed material insertion lid 11 and the mixed material take-out valve 12 are provided in the apex side of the two cone-shaped container parts 9a and 9b which comprise the said mixing container 10, respectively.

In this way, the inclined cylindrical mixer of the present invention inserts two or more kinds of mixed materials to be mixed through the mixed material insertion lid 11 formed on the apex side of the cone-shaped container portion 9a, and is connected to the rotary shaft 3. By driving the apparatus 4, the mixing vessel 10 is rotated through the rotation shaft 3 to mix the mixture materials by moving the mixing material in the mixing vessel 10.

And the moving state of the mixed material in the mixing container 10 according to the rotation of the mixing container 10 in Example 2 is set in the cone-shaped container part 9b as shown in FIG. (Arrow a) and diffusion (arrow b) in the cone-shaped container portion 9a, and the set (arrow a) and diffusion (arrow b) of the mixed material repeated by rotation of the mixing container 10. The mixing operation of the materials is performed by using the mixing action of the mixture. In the mixing operation, all the mixed materials in the mixing vessel 10 are moved by the rotation of the mixing vessel 10 as in the first embodiment. It is an object of the present invention to provide an inclined cylindrical mixer in which defects are not easily generated and in which two or more kinds of mixed materials can be efficiently mixed in a short time.

In this way, FIG. 4 is an experimental measured value which displayed the mixing efficiency in this invention compared with the conventional apparatus. In the measured value of FIG. 4, pallets of four different colors are mixed at different insertion positions, sampled at five locations for each mixing time, the content of colored pallets contained therein is measured, and standard deviations are calculated. This is indicated on the vertical axis, and the horizontal axis indicates the mixing time. In the case of the injection rate of 45% in the conventional W-type mixer, and the graph of the injection rate of 45% in the gradient cylindrical mixer of the present invention, the graph is the case of 70% of the gradient cylinder mixer of the present invention. It divides and compares the average value of the standard deviation computed for every coloring pallet.

In Fig. 4, in the inclined cylindrical mixer of the present invention, the tendency at 70% injection is approximately equivalent to that of 45% in the inclined cylindrical mixer of the present invention, and the mixing time is approximately mixed in about 15 to 20 minutes. In the case of the injection rate of 70%, the larger the injection rate is, the smaller the moving space of the mixed material is, so that the left and right positional movement is slightly lower than that of the injection rate of 45%. Since it is delayed, the fluctuation of the mixing initial stage is large.

However, in the inclined cylindrical mixer of the present invention, by forming the eastern part 8 in an inclined cylindrical shape and inclining the eastern part 8, the force acting on the mixed material near the rotation axis is large, and thus the inclined cylindrical mixer of the present invention is used. Even when the injection rate was 70%, it was confirmed that the mixing of the mixed materials can be performed sufficiently in a short time.

In addition, what was confirmed in the measured value shown in FIG. 4 is that in the conventional W cone mixer or double cone mixer, although the time to reach the level which can be said to be substantially mixed is about 30 minutes, this invention It is understood that the inclined cylindrical mixer of 45% or 70% of the injection rate has reached a level that can be said to be approximately mixed in a short time of about 15 to 20 minutes. The cylindrical mixer can improve the injection rate of the mixed material even when compared to the mixing vessel of the same capacity, and further improves the member shape of the portion for rotating the mixing vessel to the eastern portion of the inclined cylindrical shape. Of the two or more kinds of powders to be used as raw materials for food, medicine, chemicals, etc. It is possible to provide an inclined cylindrical mixer which can be mixed in a short time.

Since the present invention is simple in shape as in the conventional W cone mixer, it is relatively easy to produce even a product in which a mixing vessel is made of stainless steel which is difficult to process, and the surface of the mixing vessel is finished by mirror processing. In addition, since the shape is simple, the container rotary type inclined cylindrical mixer having a very good cleaning efficiency for each lot can be provided, and the industrial applicability is very high.
