Description

  The present invention relates to a batch-type kneading apparatus, and more particularly to a batch-type kneading apparatus suitable for kneading granular materials to be kneaded.

  Conventionally, in a batch-type kneading apparatus that completes most of the kneading process in one container, it is common to put the material to be kneaded into the container and stir the material to be kneaded with a stirring blade or the like. Note that the batch type is a term for the continuous type, and is also referred to as a batch processing type or an intermittent type, and refers to a method in which materials are stored in a container to some extent.

  However, in the conventional batch-type kneading apparatus, when the granular material to be kneaded is kneaded, the stirring blade strongly collides with the material to be kneaded, so that each particle of the material to be kneaded is finely crushed into a powder. There was a risk of loss of commercial value.

  Further, the conventional batch-type kneading apparatus has a problem that the kneading ability is low because the material to be kneaded is only stirred by the stirring blade.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a batch-type kneading apparatus that can knead a granular material to be kneaded without pulverizing and has high kneading ability.

The present invention employs the following means in order to solve the above problems.
(1) The present invention
A batch-type kneading apparatus for kneading the material to be kneaded by repeatedly acting in this order on a plurality of types of materials to be kneaded, dividing, changing direction, and collecting,
A rotating drum that is formed in a cylindrical shape and rotates along a plane of rotation parallel to the central axis thereof;
Splitting means provided in the rotary drum, and splitting the material to be kneaded charged into the rotary drum by half-rotating the rotary drum from an initial position;
Direction changing means for changing the direction of the mixed material divided by the dividing means by being further provided in the rotating drum and further rotating the rotating drum halfway;
A collecting means for collecting the materials to be kneaded provided in the rotating drum and redirected by the direction changing means.

  In the present invention, the material to be kneaded can be kneaded simply by repeatedly acting on the material to be kneaded, direction change, and assembly, and no strong impact force acts on the material to be kneaded. Therefore, the granular material to be kneaded can be prevented from being pulverized.

Further, when the rotary drum rotates N times, the material to be kneaded is divided into 2 ^N layers and stacked (aggregated), so that the kneading ability becomes very high.

  Furthermore, since the material to be kneaded can be sufficiently kneaded with one kneading apparatus, the apparatus can be miniaturized.

(2) The present invention also provides:
A batch-type kneading apparatus that kneads a plurality of kinds of materials to be kneaded by repeatedly acting in this order, division, direction change, and assembly,
A cylindrical rotating drum;
A rotating shaft provided on the rotating drum and intersecting a central axis of the rotating drum;
When the rotating drum is rotated halfway from the initial position around the rotating shaft, the material to be kneaded protrudes from the inner peripheral surface of the rotating drum toward the central axis of the rotating drum to divide the material to be kneaded, and the center A dividing plate member extending along an axis;
When the rotary drum further rotates halfway, one of the materials to be kneaded divided by the dividing plate member extends along the dividing plate member and intersects the dividing plate member in order to change the direction of the material. A direction changing plate member extending in the direction;
In order to change the direction of the other of the materials to be kneaded divided by the dividing plate member, a direction changing chamber provided on the dividing terminal end side of the dividing plate member,
In order to collect one of the materials to be kneaded changed in direction by the plate member for direction change and the other material to be kneaded changed in direction by the direction change chamber, the change terminal portion of the plate member for direction change A meeting room on the side,
It is provided with.

  In this invention, since it can be comprised by a rotating drum and the several board member provided in the rotating drum, a structure can be simplified.

  (3) It is preferable that the dividing plate member is erected in a substantially vertical direction, and the direction changing plate member is arranged in a direction substantially orthogonal to the dividing plate member.

  In this case, when the rotating drum rotates, the material to be kneaded that has fallen by its own weight in the rotating drum can be reliably divided by the dividing plate member that is erected in the substantially vertical direction. Further, it is possible to prevent the divided material to be kneaded from falling off from the direction changing plate member that is provided in a substantially horizontal direction.

  (4) It is preferable that the direction changing plate member is curved so as to be concave toward the dividing plate member side.

  Among the divided materials to be kneaded, one material to be kneaded stopped by the partition plate is caused to flow along the direction changing plate member while the rotary drum rotates from half rotation to one rotation. Further, among the divided materials to be kneaded, the other material to be kneaded whose direction has been changed in the direction changing chamber flows along the inner peripheral surface of the rotating drum.

  Here, the direction changing plate member is recessed on the dividing plate member side, that is, the inner peripheral surface of the rotating drum on which the other material to be kneaded flows (the opposite side of the dividing plate member). By making the concave in the same direction, both sides of the plate member for direction change become higher than the central part while the rotary drum makes one rotation from half rotation.

  Therefore, the material to be kneaded flowing on the direction changing plate member can be more reliably prevented from falling off.

  In addition, since the lowermost part of the direction changing plate member and the lowermost part of the inner peripheral surface of the rotating drum substantially coincide, one of the materials to be kneaded flowing along the direction changing plate member and the inner peripheral surface of the rotating drum The other material to be kneaded flowing through can be aligned (positioned).

  As a result, it is possible to prevent the divided materials to be kneaded from being displaced and unable to gather.

(5) The rotating drum is preferably a cylinder. In this case, when the material to be kneaded flows on the inner peripheral surface of the rotating drum, the material to be kneaded falls to the central portion along the arc of the inner peripheral surface by its own weight, so that the material to be kneaded can be prevented from being dispersed.

(6) It is preferable that the rotating drum is a rectangular tube having three or more corners, and the dividing plate member is provided at a corner portion of the rectangular tube.

  In this case, since both sides of the dividing plate member are inclined surfaces, when the material to be kneaded is divided, the material to be kneaded falls by its own weight along the inclined surface to a corner portion of the dividing plate member. The material can be prevented from dispersing.

  As described above, according to the present invention, the material to be kneaded can be kneaded without applying a strong impact force, so that the granular material to be kneaded can be prevented from being pulverized and the commercial value can be prevented from being lowered. it can.

Further, by rotating the rotary drum N times, the materials to be kneaded can be stacked and gathered in 2 ^N layers, so that the kneading ability can be greatly increased and the apparatus can be miniaturized.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  More specifically, as shown in FIGS. 1 to 3, the batch-type kneading apparatus 1 includes a cylindrical rotary drum 12 and a rotation provided on the rotary drum 12 and intersecting the central axis 10 of the rotary drum 12. The shaft 11 and the rotary drum 12 are half-rotated from the initial position (see FIG. 6) around the rotary shaft 11 (see FIGS. 6 to 12), so that the material A to be kneaded charged into the rotary drum 12 is obtained. , B is provided with a dividing plate member 13 that protrudes from the inner peripheral surface of the rotating drum 12 toward the central axis 10 side of the rotating drum 12 and extends along the central axis 10.

  In addition, as shown in FIGS. 2A and 2B, the batch kneading apparatus 1 is configured such that the rotating drum 12 is further rotated halfway (see FIGS. 13 to 17), whereby the dividing plate member 13 is used. In order to change the direction of the materials to be kneaded A + B and A + B divided by the above, the material extends along the dividing plate member 13 and intersects the dividing plate member 13, in this embodiment, with respect to the dividing plate member 13. There are provided a direction changing plate member 14 extending in a substantially orthogonal direction, and first and second direction changing chambers 16a and 16b.

  The part of the dividing plate member 13 where the division is started is called a division start end part 13a, and the part where the division is finished is called a division end part 13b. Further, the portion of the direction changing plate member 14 where the direction change is started is called a change start end portion 14a, and the portion where the direction change is finished is called a change end portion 14b.

  As shown in FIG. 2 (b), the direction changing plate member 14 is formed in an arc shape in cross section, and the change starting end portion 14a side at one side end 14c is joined to the dividing plate member 13, and the other side. The end 14 d is joined to the inner peripheral surface 12 c of the rotary drum 12 as a whole.

  Further, as shown in FIG. 2A, the batch type kneading apparatus 1 is configured to collect the materials to be kneaded A + B and A + B divided by the dividing plate member 13 so as to collect the conversion end of the direction changing plate member 14. A collecting chamber 15 is provided between the portion 14 b and the inner end surface 12 a of the rotary drum 12.

  Next, each of the above components will be described. The rotary drum 12 is formed in a cylindrical shape. The dividing start end portion 13 a of the dividing plate member 13 is separated from the inner end surface 12 a of the rotary drum 12 by a predetermined distance.

  The collecting chamber 15 is provided between the dividing start end portion 13 a of the dividing plate member 13 and the inner surface 12 a of the one lid 19 of the rotating drum 12 (the other inner end surface of the rotating drum 12).

  In addition, the split end portion 13 b of the split plate member 13 is in contact with the inner surface 12 b (the inner end surface of the rotary drum 12) of the other lid 18 of the rotary drum 12.

  As shown in FIG. 4, the dividing plate member 13 protrudes from the inner peripheral surface 12 c of the rotary drum 12 toward the central axis 10. As shown in FIG. 1, the height h of the dividing plate member 13 is gradually increased from the dividing start end portion 13a side to the dividing end end portion 13b side.

  As shown in FIG. 3, the direction changing plate member 14 is formed to have substantially the same length as the dividing plate member 13. As shown in FIG. 4, the direction changing plate member 14 is expanded in a direction crossing the dividing plate member 13. In the present embodiment, the direction changing plate member 14 is expanded in a direction substantially orthogonal to the dividing plate member 13.

  The width b of the direction changing plate member 14 is substantially the same as the radius of the inner peripheral surface 12c of the rotary drum 12 on the separation start end portion 14a side, and the width b of the inner peripheral surface 12c of the rotary drum 12 on the separation end portion 14b side. It is almost the same as the diameter. That is, the width b gradually increases from the division start end portion 14a to the division end portion 14b.

Also, as shown in FIG. 2, a predetermined gap d is provided between the direction changing plate member 14 and the dividing plate member 13 from the change terminal portion 14b of the direction changing plate member 14 to a predetermined distance. Is provided. In the present embodiment, the change start end portion 1 b of the direction change plate member 14 is changed to the change start end portion 1.
The gap d gradually decreases toward the 4a side.

  There is no gap d from the change starting end portion 14a of the direction changing plate member 14 to a certain extent. This is to prevent the material to be kneaded A + B in the first direction change chamber 16a and the material A + B in the second direction change chamber 16b from being mixed as will be described later.

  As will be described later, when the materials to be kneaded A and B are kneaded, the materials A and B to be kneaded flowing from the switching start end portion 14a to the switching end portion 14b of the direction changing plate member 14 are separated by this gap d. It spreads to the opposite side of the plate member 13 and flows through the central portion of the direction changing plate member 14.

  As shown in FIG. 4, the direction changing plate member 14 is curved so as to be concave toward the dividing plate member 13 side. That is, the direction changing plate member 14 is curved in the same direction as the inner peripheral surface 12 c on the opposite side of the rotary drum 12 from the dividing plate member 13.

  On the split end portion 13b side of the split plate member 13, that is, on the switch start end portion 14a side of the direction changing plate member 14, as shown in FIG. It is divided into two by the conversion plate member 14. Here, the space on the right side in FIG. 5 is called the first direction change chamber 16a, and the space on the left side is called the second direction change chamber 16b.

  Next, the operation of the batch kneader 1 will be described. As shown in FIG. 6, when the materials A and B to be kneaded are kneaded by the batch kneader 1, first, the central axis 10 of the rotary drum 12 of the batch kneader 1 is directed substantially in the vertical direction. Stop in a standing position. This state is referred to as the initial position of the rotating drum 12.

  In this initial position, the division start end portion 13a of the division plate member 13 is arranged on the lower side, and the division end portion 13b is arranged on the upper side. Further, the collecting chamber 15 is disposed on the lower side, and the first and second direction changing chambers 16a and 16b are disposed on the upper side.

  Next, the upper lid 18 (on the side of the terminating end portion 13 b) is opened, and a predetermined amount of the materials to be kneaded A and B is put into the rotary drum 12. The materials A and B to be kneaded are deposited in the collecting chamber 15.

  The allowable amount of the materials A and B to be mixed is determined by the capacity of the collecting chamber 15 and the width b of the direction changing plate member 14. After the materials to be mixed A and B are charged, the lid 18 is closed.

  Next, as shown in FIG. 7, the dividing plate member 13 coincides with the rotating surface around the rotating shaft 11, and the materials to be kneaded A and B (hereinafter referred to as A + B) are on the dividing plate member 13 side. The rotating drum 12 is rotated in a predetermined direction R so that the dividing plate member 13 moves downward.

  As the rotation of the rotary drum 12 progresses, as shown in FIG. 8, the materials to be kneaded A + B accumulated in the collecting chamber 15 of the rotary drum 12 are separated from the division start end portion 13a of the division plate member 13 to the division end portion 13b side. Flowing into.

  As described above, the inner peripheral surface 12c of the rotary drum 12 is curved so as to be concave toward the dividing plate member 13 (see FIG. 4). Further, as shown in FIG. 9, the dividing plate member 13 becomes lower than the collecting chamber 15 when the rotary drum 12 is rotated 90 to 180 degrees from the initial position.

For this reason, as the rotation of the rotating drum 12 proceeds, the material to be kneaded A + B in the collecting chamber 15 flows separately on both sides of the dividing plate member 13 on the inner peripheral surface 12 c of the rotating drum 12. Thus, the material to be kneaded A + B is divided in the horizontal direction by the dividing plate member 13.

  When the rotating drum 12 rotates more than 90 degrees from the initial position, as shown in FIG. 10, one of the materials to be kneaded A + B and A + B divided by the dividing plate member 13 (the right side in FIG. 9). The material to be kneaded A + B (approximately half of the whole) flows into the first direction change chamber 16a.

  Further, among the materials to be kneaded A + B and A + B divided by the dividing plate member 13, the other material to be kneaded (the left side in FIG. 9) A + B (substantially half of the whole) is the second as shown in FIG. It flows into the direction change chamber 16b.

  When the rotating drum 12 is rotated halfway (180 degrees) from the initial position and turned upside down, that is, as shown in FIG. 12, the collecting chamber 15 is disposed on the upper side, and the first direction changing chamber 16a and When the second direction change chamber 16b is disposed on the lower side, the divided materials to be kneaded A + B and A + B are accumulated in the first chamber 16a and the second chamber 16b.

  The first direction changing chamber 16 a is expanded laterally from the space between the dividing plate member 13 and the inner peripheral surface 12 c of the rotary drum 12. For this reason, the materials to be kneaded A + B deposited in the first direction change chamber 16a are deposited in a horizontally long flat shape.

  In this way, the material to be kneaded A + B is divided into two by the dividing plate member 13 when the rotary drum 12 rotates halfway (0 degree to 180 degrees) from the initial position.

  Next, when the rotating drum 12 rotates more than 180 degrees from the initial position, as shown in FIG. 13, the material to be kneaded A + B whose direction has been changed by the first direction changing chamber 16 a becomes the inner peripheral surface of the rotating drum 12. It flows along 12c. In addition, the material to be kneaded A + B in the second direction changing chamber 16 b flows on the direction changing plate member 14.

  The direction changing plate member 14 is curved so as to be concave toward the dividing plate member 13 as described above, and further, there is a gap between the direction changing plate member 14 and the dividing plate member 13 from the middle. Since d is formed, as shown in FIG. 14, as the rotary drum 12 rotates, the material to be kneaded A + B flowing on the direction changing plate member 14 spreads on both sides of the dividing plate member 13 from the middle. , And flows through the central portion of the direction changing plate member 14.

  At this time, the part of the divided material to be kneaded A + B that flows on the direction changing plate member 14 and the part that flows along the inner peripheral surface 12c of the rotary drum 12 are separated vertically, and the upper and lower materials to be kneaded are separated. The materials A + B and A + B flow while being aligned with each other.

  That is, the material to be kneaded A + B (see FIG. 10) divided right and left by the dividing plate member 13 is turned up and down by the direction changing plate member 14.

  When the rotating drum 12 rotates more than 270 degrees from the initial position, the material to be kneaded A + B that flows along the inner peripheral surface 12c of the rotating drum 12 flows into the collecting chamber 15 as shown in FIG.

  Further, the material to be kneaded A + B that has flowed on the direction changing plate member 14 also flows into the collecting chamber 15. Then, as shown in FIG. 16, the materials to be kneaded A + B and A + B that have flowed separately in the vertical direction are stacked and assembled in the collecting chamber 15.

The rotating drum 12 makes one rotation (360 degrees) from the initial position, and as shown in FIG.
When 5 is on the lower side and the first direction change chamber 16a and the second direction change chamber 16b are arranged on the upper side, the materials to be kneaded A + B and A + B are accumulated in the collecting chamber 15.

  At this time, the materials to be kneaded A + B are stacked and assembled in two layers. That is, when the rotary drum 12 rotates once from the initial position, the material to be kneaded A + B is divided into two layers (A + B, A + B) and assembled (laminated).

  Next, the rotating drum 12 is rotated for the second time. In this case, at the beginning of rotation (0 to 180 degrees), as shown in FIG. 18, the materials to be kneaded (A + B) and (A + B) that are stacked vertically flow to the dividing plate member 13 side.

  As the rotation proceeds, as shown in FIG. 19, the materials to be kneaded (A + B) and (A + B) that have been stacked one above the other are divided into left and right by the dividing plate member 13.

  Then, when the rotary drum 12 is rotated a second time (half rotation (180 degrees)) from the initial position, as shown in FIG. 20, the material to be kneaded (A + B) and (A + B) is divided into the left and right first parts. It will be in the state isolate | separated into the 1 direction change chamber 16a and the 2nd direction change chamber 16b.

  When the rotating drum 12 further rotates (half rotation or more (180 degrees or more) from the initial position), as shown in FIG. 21, the upper and lower layers of the materials to be kneaded (A + B) and (A + B) are for direction change. It flows to the collecting chamber 15 side on the plate member 14 or along the inner peripheral surface 12c of the rotary drum 12.

  When the rotating drum 12 rotates more than 270 degrees from the initial position, as shown in FIG. 22, two layers of materials to be kneaded (A + B) and (A + B) flowing along the inner peripheral surface 12c of the rotating drum 12 Flows into the collecting chamber 15.

  Further, the two layers of the materials to be kneaded (A + B) and (A + B) flowing on the direction changing plate member 14 are also the two layers of the materials to be kneaded (A + B) and (A + B) deposited in the collecting chamber 15. Flows up.

  When the rotary drum 12 completes the second rotation, all the materials to be kneaded A + B are deposited in the collecting chamber 15 as shown in FIG. At this time, the materials to be kneaded A + B are stacked and assembled in four layers.

Similarly, when the rotary drum 12 continues to rotate three or more times, the material to be kneaded A + B is repeatedly divided, redirected, and assembled (laminated). When the rotary drum 12 rotates N times, the material to be kneaded A + B is divided into 2 ^N layers and stacked (assembled). Thereby, the materials A and B to be kneaded are sufficiently kneaded.

  As described above, the batch-type kneading apparatus 1 of the present invention kneads the materials to be kneaded A, B by repeatedly dividing, changing the direction, and gathering, so that the materials to be kneaded A, B have a strong impact force. There is no addition.

  Therefore, even if the materials A and B to be kneaded are granular, it can be prevented from being pulverized by kneading, so that the commercial value can be prevented from decreasing.

Further, when the rotary drum 12 rotates N times, the material to be kneaded A + B is divided into 2 ^N layers and stacked, so that the kneading ability becomes very high and the apparatus can be downsized.
