Description

  The present invention relates to a substance transfer device for transferring a substance from an inlet to an outlet.

2. Description of the Related Art A material transfer device is known in which a fluid containing solid matter is input (supplied) from an inlet and supplied (discharged) from an outlet. Such a material transfer device is used, for example, when transferring a fluid from a large container (such as a tank) containing a large amount of fluid to a large number of small containers. As a conventional substance transfer device, one in which a spiral blade is attached to the outer peripheral surface of a cylindrical rotating member is known (for example, see Patent Document 1). When a substance is transferred using this conventional substance transfer device, the amount of substance that can be transferred increases as the rotational speed of the cylindrical rotating member increases. Moreover, the discharge pressure (momentum) when the substance is discharged from the outlet also increases as the rotational speed of the rotating member is increased.
JP 2003-269358 A

  However, there is a limit to the rotation speed of the rotating member described above, and if the rotating member is rotated quickly, the material put in from the inlet may be damaged. In addition, depending on the type of substance to be transferred, there are some that are easily damaged, and thus the rotating member may not be able to rotate quickly. Further, when a transfer pipe or the like exists between the outlet of the substance transfer device and a small container, it is necessary to increase the discharge pressure of the substance at the outlet of the substance transfer device to some extent. When this discharge pressure is small, there is a possibility that the substance stays inside the transfer pipe.

  In view of the above circumstances, the present invention can not only transfer a large amount of material per unit area and unit time without damaging the material, but also can vigorously eject the material transferred to the outlet from the outlet (can be discharged at a high discharge pressure). An object is to provide a mass transfer device.

In order to achieve the above object, the mass transfer apparatus of the present invention is a mass transfer apparatus for transferring a substance from an inlet where a substance is placed to an outlet where the substance is discharged.

(3) The rotary member is provided with a blade formed in a spiral shape on the outer peripheral surface of the rotary member and rotating together with the rotary member.

here,
(4) The internal space has a conical shape or a truncated cone shape,
(5) The rotating member may have a conical shape or a truncated cone shape.

Also,
(6) The internal space of the housing and the rotating member may be similar.

further,
(7) The blade may extend from the outer peripheral surface of the rotating member to a position close to the inner peripheral surface of the casing.

Furthermore,
(8) The blade may extend continuously from a portion near the inlet to a portion near the outlet on the outer peripheral surface of the rotating member.

Furthermore,
(9) The distance between the surfaces of the blades facing each other may be longer as the distance to the outlet is approached.

Furthermore,
(10) You may provide the 2nd blade | wing which extends the said outer peripheral surface of the said rotation member helically so that it may not contact this blade | wing from the surface which mutually faces among the said blade | wings.

Furthermore,
(11) The blade may be thicker as it approaches the outlet.

Furthermore,
(12) When the tangent at the boundary between the blade and the outer peripheral surface is translated toward the central axis and the tangent intersects the central axis, the inclination angle formed by the tangent and the central axis is You may comprise so that it may become so small that it approaches an exit.

Furthermore,
(13) You may provide the shielding wall which spreads between the parts which face each other among the said blade | wings, and extends in parallel with the said outer peripheral surface of the said rotation member which shields this outer peripheral surface from the said inner peripheral surface of the said housing | casing.

Furthermore,
(14) The inlet may be formed so that a substance can be introduced from a direction intersecting the rotation axis or from a direction parallel to the rotation axis.

Furthermore,
(15) The rotating member may have a barrier plate formed on the bottom surface of the rotating member that prevents a substance being transferred from colliding with the bottom surface of the casing.

Furthermore,
(16) The substance may be either a fluid or a mixture of solids in the fluid.

  The outer shape of the rotating member includes all shapes whose thickness (or outer diameter) gradually increases as it approaches the outlet from the inlet, and the contour of the outer peripheral surface in the side view of the rotating member is a parabola or index. The outer shape may be a curve, a hyperbola, or the like.

  In the substance transfer device of the present invention, since the blade can be brought close to (approaching) the inner peripheral surface of the casing to the extent that the rotation of the blade is not hindered, the outer peripheral surface of the rotating member, the spiral blade, A space surrounded by the peripheral surface becomes a material transfer path (transfer space). Since this transfer path extends continuously along the spiral blade, the transfer path is formed in a spiral shape on the outer peripheral surface of the rotating member. The rotating member extends from the inlet to the outlet while increasing its thickness (or outer diameter), so that the apex (or the top surface, the thinnest part) is located near the inlet, and the bottom surface (thickest part) Will be located near the exit. For this reason, a rotating member becomes thick, so that an exit is approached (an outer diameter becomes large). Therefore, when the rotating member is rotating at a constant speed, the peripheral speed of the outer peripheral surface of the rotating member is closer to the exit (the moving distance per rotation of the fixed point on the outer peripheral surface of the rotating member is longer), In other words, the circumferential speed increases as the distance from the central axis of the rotating member increases. That is, in the transfer path that continues from the inlet to the outlet, the peripheral speed increases as the portion is closer to the outlet, depending on the thickness (outer diameter) of the rotating member. For this reason, the substance put in from the inlet reaches the transfer path, and is transferred toward the outlet while gradually increasing the transfer speed substantially in proportion to the peripheral speed. Since the rotating member is thin in the vicinity of the entrance in the transfer path, the speed at which the substance is transferred is not so fast as to damage the substance.

  As described above, since the material transfer speed is substantially proportional to the peripheral speed on the outer peripheral surface of the rotating member, the material transfer speed gradually increases in proportion to (in association with) the gradually increasing peripheral speed. The material being transferred is smoothly transferred to the outlet while forming a laminar flow (without forming a turbulent flow) without causing a rapid change in velocity. Thus, since the material transfer speed is faster when the outlet is reached than the inlet, the substance transferred to the outlet is ejected vigorously from the outlet according to the rotational speed of the rotating member (discharged at a high discharge pressure). Will be). In addition, since a laminar flow of material is formed in the transfer path as described above, the material being transferred does not collide violently with the inner peripheral surface and blades of the housing, and noise and vibration due to this collision are generated. And the material is not damaged.

  By the way, as the transfer path is closer to the outlet as described above, the transfer speed becomes faster. Therefore, the amount of substance introduced from the inlet (supply amount) and the amount of substance exited from the outlet (discharge amount) per unit area and unit time. When compared in, the amount of emissions should be greater than the amount supplied. However, in actuality, only a quantity of the substance put in from the inlet comes out from the outlet, so that a force acts to suck the substance put in from the inlet into the back of the transfer path (toward the outlet). Therefore, even if a large amount of substance is put in one after another from the inlet, it can be smoothly transferred to the outlet without clogging, and the substance can be discharged from this outlet.

  The present invention has been realized in a substance transfer device that transfers foods and foods such as dairy products and seasonings, chemicals such as paints, cosmetics such as creams, and pharmaceuticals such as ointments.

  A first embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a schematic view showing a mass transfer system in which a mass transfer apparatus according to a first embodiment of the present invention is arranged. FIG. 2 is a side view of the substance transfer device of FIG. 3 (a) is a side view showing a rotating member and blades of the substance transfer device shown in FIG. 2, and FIG. 3 (b) is a side view showing another example of the internal space (the same applies to the rotating member). (C) is a side view which shows the further another example of internal space (a rotation member is also the same). 4 is a cross-sectional view taken along the line BB in FIG. FIG. 5 is a graph showing a comparison of the amount transferred by the material transfer device of Example 1 and the material transfer device of the comparative example, where the horizontal axis represents the number of rotations (rpm) of the rotating member, and the vertical axis represents the transfer at the outlet. It represents the transfer amount (L / min (liter per minute)) per 1 cm ^{2 of} the surface orthogonal to the direction. FIG. 6 is a graph showing the pressure at the inlet and the outlet, where the horizontal axis represents the length direction of the casing, and the vertical axis represents the pressure at the water column (m).

  As shown in FIG. 1, for example, the substance transfer apparatus 10 is configured such that a large number of small containers 6-1 and 6-2 are transferred from a large container (tank or the like) 2 in which a large amount of fluid is stored via transfer pipes 4A and 4B. Used to transfer fluid to ... The substance transfer apparatus 10 is attached between the transfer pipes 4A and 4B (connection portion), and the substance that has fallen from the container 2 to the inlet 12 of the substance transfer apparatus 10 by gravity is transferred to the outlet 14 to the transfer pipe 4B. It discharges (discharges, discharges). A number of small containers 6-1, 6-2,... Are sequentially conveyed by the conveyance belt 8 in the direction of arrow A.

As shown in FIG. 2 and the like, the substance transfer device 10 includes an inlet 12 through which a substance is introduced (supplied) and an outlet 14 through which the substance entered from the inlet 12 is discharged (discharged and discharged). A formed casing (casing) 20 is provided. The inlet 12 and outlet 14 have circular cross sections (surfaces orthogonal to the material inflow / outflow direction (directions indicated by arrows IN and OUT)). An internal space 22 is formed in the housing 20, and the internal space 22 extends from the inlet 12 to the outlet 14 while increasing its inner diameter. That is, the internal space 22 gradually expands so that the inner diameter R2 near the inlet 12 is the smallest and the inner diameter R1 near the outlet 14 is the largest. As for the shape of the internal space 22, a frustoconical shape is shown in the side view of FIG. 1, but it may be conical. Further, the shape of the internal space 22 may be such that the side view is widened as shown in FIG. 3 (b), and the side view is like a bullet as shown in FIG. 3 (c). It may be. The casing 20 is formed with an inner peripheral surface 24 that defines an internal space 22, and the inner peripheral surface 24 corresponds to, for example, a frustoconical outer peripheral surface. The outlet 14 is provided with a flow meter 16 for measuring the flow rate of the substance exiting from the outlet 14. According to the flow meter 16, the transfer amount (L / min (liter per minute)) per 1 cm ² of the cross section of the outlet 14 (surface perpendicular to the direction in which the substance is discharged (direction of arrow OUT)) is measured. A pressure gauge 13 for measuring the pressure due to the fluid at the inlet 12 is arranged at the inlet 12, and a pressure gauge 15 for measuring the pressure due to the fluid at the outlet 14 is arranged at the outlet 14. An example of the pressure measured by these pressure gauges 13 and 15 is shown in FIG. As the pressure gauge 13, a manometer manufactured by Plant Construct and Engineering Co., Ltd. (measurement unit is water column (m)) is used. As the pressure gauge 15, a Bourdon tube pressure gauge manufactured by Daiichi Keiki Seisakusho Co., Ltd. It was a pressure gauge, and the unit of measurement was converted to a water column (m) using a MPa, and a graph described later was created. As the flow meter 16, a float type flow meter (flow meter, measurement unit is L / min) manufactured by Tokyo Instrumentation Co., Ltd. was used. The flow meter 16 can measure only the flow rate of water.

  A rotating member 30 that rotates in the internal space 22 is accommodated in the internal space 22 of the housing 20. The rotating member 30 extends from the inlet 12 to the outlet 14 while increasing its thickness (corresponding to the outer diameter in the case of a cone shape or a truncated cone shape). The rotating member 30 is preferably similar in shape to the internal space 22, but may not be similar. In the first embodiment, since the shape of the internal space 22 is a truncated cone shape, the shape of the rotating member 30 is also a truncated cone shape as shown in FIG. 2 and FIG. When the internal space 22 of the housing 20 and the rotating member 30 are formed in a conical shape or a truncated cone shape, these can be easily manufactured, and the material can be transferred smoothly. Further, when the internal space 22 and the rotating member 30 are similar, it is convenient for manufacturing the substance transfer device 10.

  The rotating member 30 rotates about a straight line 36 (virtual line) passing through the center point of the circular top surface 32 and the center point of the circular bottom surface 34 as a central axis. Here, the central axis 38 concentric with the straight line 36 is set as the rotation center of the rotary member 30. Both ends in the longitudinal direction of the central shaft 38 are fixed to the bearings 40 and 42 so as to be freely rotatable. A portion of the central shaft 38 that is rotatably fixed to the bearing 42 is connected to a motor 44, and the rotating member 30 is rotated by driving the motor 44. The motor 44 is controlled by a controller (not shown). On the bottom surface 34 of the rotating member 30 is fixed (formed) a barrier plate 35 that prevents the substance being transferred from colliding with the bottom surface of the housing 20 (the bottom surface of the inner wall). The dam plate 35 is wider than the bottom surface 34 (having a larger outer diameter) and is substantially equal to the outer diameter of the blade 50 near the bottom surface 34. The top surface 32 and the dam plate 35 of the rotating member 30 are configured not to contact the inner wall surface of the casing 20, and the rotating member 30 rotates smoothly without contacting the fixed and non-rotating casing 20.

  A spiral blade 50 is formed on the outer peripheral surface 31 of the rotating member 30, and the blade 50 rotates together with the rotating member 30. The blade 50 extends spirally from the front end to the rear end (from end to end) of the outer peripheral surface 31 of the rotating member 30. However, the blades 50 may be configured to extend continuously from the vicinity of the inlet 12 to the vicinity of the outlet 14 of the outer peripheral surface 31 instead of from end to end. Therefore, as will be described later, the rotating member 30 may be configured such that there are no blades 50 at both ends in the longitudinal direction. The blade 50 extends from the outer peripheral surface 31 of the rotating member 30 to a position close to the inner peripheral surface 24 of the housing 20, and the tip of the blade 50 (the portion facing the inner peripheral surface 24) and the inner peripheral surface 24. Material is hardly leaked from the gap. The distance (spacing) d between the surfaces of the blades 50 facing each other is constant (any position on the surface is the same). Further, the blade 50 and the inner peripheral surface 24 are not in contact with each other, and there is no hindrance to the rotation of the blade 50. In addition, the housing | casing 20 is being fixed so that it may not rotate, and the leg (not shown) for stably arrange | positioning on the floor etc. is attached.

  When the tangent line 52 at the boundary between the outer peripheral surface 31 of the rotating member 30 and the blade 50 is translated toward the central axis 38 (straight line 36) and the tangent line 52 intersects the central axis 38, the tangent line 52 and the central axis 38 The formed inclination angle θ is constant and 84 ° as shown in FIG. In order to increase the transfer amount of the substance, the inclination angle θ may be changed as described later.

  The above-described various parts (the casing 20, the rotating member 30, the blade 50, etc.) are made of metal, resin, or the like depending on the substance to be transferred. Examples of the substance transferred by the substance transfer apparatus 10 include foods / foodstuffs, chemicals, cosmetics / detergents, and pharmaceuticals. Examples of food / food products include dairy products, seasonings, cooked foods, beverages, alcoholic beverages, and confectionery products. Examples of chemical products include paints. Examples of cosmetics and detergents include creams, shampoos, and detergents. Examples of pharmaceuticals include ointments, eye drops, glycerin and the like.

  The diameter R1 of the bottom surface of the internal space 22 of the housing 20 is 18 cm, the diameter R2 of the top surface is 4 cm, the length L1 of the internal space 22 (also the length of the rotating member 30) is 20.7 cm, The diameter R5 of the circular inlet 12 is a diameter that doubles the cross-sectional area of the outlet 14, and the diameter R6 of the outlet 14 is 2.0 cm. The diameter R3 of the bottom surface of the rotating member 30 was 13 cm, the diameter R4 of the top surface was 1.3 cm, and the distance (interval) d between the surfaces of the blades 50 facing each other was 2.5 cm. The amount transferred in this way was measured. In Example 1, water was transferred as a substance. Other examples described later also used water as a substance. The measurement results are shown in FIG. FIG. 5 also shows the flow rate of the material transfer device of the comparative example. In the substance transfer device of the comparative example, the inner space of the rotating member and the casing is cylindrical, the inner space has a diameter of 7 cm, the diameter (outer diameter) of the rotating member is 1.3 cm, and other parts are substances. It was the same as the transfer device 10 and the same size. In this measurement, the flow rate was measured using the flow meter 16, and the material transfer device 10 and the material transfer device of the comparative example were made of resin.

  As shown in FIG. 5, the flow rate of the mass transfer device 10 of Example 1 and the mass transfer device of the comparative example increase in proportion to the rotation speed (rpm), but the increase rate of the flow rate with the increase of the rotation speed is The mass transfer device 10 is much larger.

  FIG. 6 shows the result of measuring the pressure at the inlet 12 and the outlet 14 of the mass transfer device 10 having the above size. In FIG. 6, the pressure is indicated by the height (m) of the water column, the pressure at the inlet 12 is negative, and the pressure at the outlet 14 exceeds 2 m. From this result, it is considered that a negative pressure is generated at the inlet 12 so as to suck the substance into the inside.

  The reason why it becomes as shown in FIGS. 5 and 6 will be examined.

  In the substance transfer device 10, the blade 50 is brought close to (approaching) the inner peripheral surface 24 of the housing 20 to the extent that there is no hindrance to the rotation of the blade 50, and the substance is released from the gap between the blade 50 and the inner peripheral surface 24. Since it is considered that there is no leakage, the substance transfer path (transfer space) 60 is a space surrounded by the outer peripheral surface 31 of the rotating member 30, the spiral blade 50, and the inner peripheral surface 24 of the housing 20. Since the transfer path 60 continuously extends spirally along the spiral blade 50, the transfer path 60 is formed on the outer peripheral surface 31 of the rotating member 30 in a spiral shape.

  The rotating member 30 extends from the inlet 12 to the outlet 14 while increasing its outer diameter (minimum is R4 and maximum is R3), so that the top surface 32 is located in the vicinity of the inlet 12, and its bottom surface 34 is It will be located in the vicinity of the outlet 14. For this reason, the rotating member 30 becomes thicker as it approaches the outlet 14. Therefore, when the rotating member 30 is rotating at a constant speed, the peripheral speed of the outer peripheral surface 31 is closer to the outlet 14 (the moving distance per rotation of the fixed point of the outer peripheral surface 31 of the rotating member 30 is larger). In other words, the peripheral speed of the fixed point of the outer peripheral surface 31 increases as the distance from the central axis 38 of the rotating member 30 increases (closer to the outlet 14). That is, in the transfer path 60 that spirally extends from the inlet 12 to the outlet 14, the peripheral speed gradually increases as the portion is closer to the outlet 14 according to the outer diameter of the rotating member 30. For this reason, the substance put in from the inlet 12 reaches the transfer path 60 in the vicinity of the inlet 12, and the transfer path 60 gradually increases (accelerates) the transfer speed almost in proportion to the peripheral speed. ) It will be transferred toward the outlet 14. The flow at this time is indicated by a spiral two-dot chain line F. On the other hand, in the substance transfer device of the comparative example, both the internal space and the rotating member are cylindrical, so that the transfer speed at the inlet and the transfer speed at the outlet are substantially the same.

  As described above, in the substance transfer device 10, the substance transfer speed is substantially proportional to the peripheral speed on the outer peripheral surface 31 of the rotating member 30, and therefore the substance transfer speed is substantially proportional to (with) the gradually increasing peripheral speed. The velocity also increases gradually, and the material being transferred forms a laminar flow (refers to a flow with less turbulence) (a turbulent flow (refers to a flow with a lot of turbulence)) without causing rapid fluctuations in the transfer rate. (Without) smooth transfer to the outlet 14. Thus, since the material transfer speed is faster when the outlet 14 is reached than the inlet 12, the substance transferred to the outlet 14 is ejected from the outlet 14 according to the rotational speed of the rotating member 30 ( (It is discharged at a high discharge pressure). Further, since a laminar flow of material is formed in the transfer path 60 as described above, the material being transferred does not collide violently with the inner peripheral surface 24 or the blades 50 of the housing 20, and noise resulting from this collision. No vibration and no material damage.

  As described above, in the transfer path 60 of the substance transfer apparatus 10, the transfer speed becomes faster as it approaches the outlet 14, so the amount of substance introduced from the inlet 12 (supply amount) and the amount of substance exited from the outlet 14 (discharge amount). When the unit is compared per unit area and unit time, the discharge amount should be larger than the supply amount. However, in reality, only the amount of the substance put in from the inlet 12 comes out from the outlet 14, so that the substance put in from the inlet 12 is sucked into the back of the transfer path 60 (toward the outlet 14) as shown in FIG. Such a force (negative pressure) acts. Therefore, even if a large amount of substance is put in one after another from the inlet 12, it can be smoothly transferred to the outlet 14 without clogging and discharged from the outlet 14. On the other hand, in the substance transfer device of the comparative example, since the internal space and the rotating member are cylindrical, the transfer amount in the vicinity of the inlet and the transfer amount in the vicinity of the outlet are the same.

  Here, a design method of the length of the casing 20 (the length of the rotating member 30), the number of turns of the blade 50, the distance d between the blades, and the inclination θ of the blade 50 will be described.

The length of the rotating member 30 is L1, the diameter of the bottom surface of the rotating member 30 is R3, the distance between the facing blades 50 is d, the number of turns of the blades 50 is N, and the inner diameter of the inner space 22 near the outlet 14 Is R1 (approximately equal to the diameter of the end portion of the blade 50), and the inclination angle of the blade 50 with respect to the central axis 38 is θ, L1 = dxN, θ = 90 ° − (tan ⁻¹ (d / 3.14xR1) )) °, solid width W <d, solid thickness H <(R1−R3) / 2, and the solid depth is B, the maximum diameter of the solid d1 = (W ² + H ² + B) ² ) ^1/2
Here, d1 <d.

  The diameter R6 of the outlet 14 is determined from the maximum diameter d1 of the solid matter and the required flow rate, and the diameter R5 of the inlet 12 is set to be two to three times as large as the cross-sectional area ratio than the diameter R6 of the outlet 14. Note that the distance between the blade 50 and the inner peripheral surface of the housing 20 is preferably in the range of 0.01 mm to 0.2 mm in consideration of leakage of substances being transferred, processing, assembly restrictions, and the like. .

  With reference to FIG. 7 and FIG. 8, Example 2 of the substance transfer apparatus of this invention is demonstrated.

FIG. 7 is a side view illustrating a rotating member and blades of the substance transfer device according to the second embodiment. FIG. 8 is a graph showing a comparison of the amounts transferred by the substance transfer device of Example 2 and the substance transfer device of Example 1, in which the horizontal axis represents the number of rotations (rpm) of the rotating member, and the vertical axis represents the outlet. It represents the transfer amount per 1 cm ^{2 of} the surface perpendicular to the transfer direction (L / min (liter per minute)). In these drawings, the same components as those shown in FIGS. 1 to 6 are denoted by the same reference numerals.

  The basic structure of the mass transfer device 110 of the second embodiment is the same as that of the mass transfer device 10 of the first embodiment, and the difference from the mass transfer device 10 is the shape of the blades. The distance (interval) d between the mutually facing surfaces of the blades 150 of the substance transfer device 110 becomes longer toward the outlet 14 (see FIG. 2 and the like). Specifically, the distance d in the vicinity of the inlet 12 (see FIG. 2, etc.) is 2.5 cm, and the distance d5 in the vicinity of the outlet 14 is 6.7 cm. ) Was increased to 3.0 cm, 3.75 cm, 4.75 cm. Note that the number of turns of the blade 150 is smaller than the number of turns of the blade 50 of the first embodiment (from eight turns to six turns).

  By gradually increasing the distances d to d5 from the inlet 12 to the outlet 14 in this way, the cross section of the transfer path 160 (the plane perpendicular to the transfer direction) becomes wider toward the outlet 14, so that the substance is further increased. It can be transported smoothly and in large quantities. However, when the distance d becomes too long, the substance tends to stay in the transfer path 160 and turbulence tends to occur. In order to prevent the occurrence of this turbulent flow, a second blade described later is formed. Here, the transfer amounts by the substance transfer device 110 of the second embodiment and the substance transfer device 10 of the first embodiment in which the distance d is changed are compared and shown in FIG.

  As shown in FIG. 8, the flow rate of the mass transfer device 10 of Example 1 and the mass transfer device 110 of Example 2 increase in proportion to the rotation speed (rpm). The material transfer device 110 is larger. The reason for this is that, as described above, the cross section of the transfer path 160 (the plane orthogonal to the transfer direction) is widened so that a larger amount of material can be transferred. This is because a force (negative pressure) that sucks into the back (toward the outlet 14) acts. However, when the distance d5 is increased unnecessarily, the substance tends to stay in the transfer path 160 as described above, and turbulence is likely to occur.

  The distances d to d5 are based on the design method of the length of the casing 20 (the length of the rotating member 30), the number of turns of the blade 50, the distance d between the blades, and the inclination θ of the blade 50 described in the first embodiment. Will be determined.

  A third embodiment of the substance transfer device of the present invention will be described with reference to FIGS.

FIG. 9 is a side view illustrating a rotating member and blades of the substance transfer device according to the third embodiment. FIG. 10 is a graph showing a comparison of transfer amounts by the substance transfer device of Example 3 and the substance transfer devices of Example 1 and Example 2, and the horizontal axis represents the number of rotations (rpm) of the rotating member, and An axis | shaft represents the transfer amount (L / min (liter per minute)) per 1 cm < ² > of the surface orthogonal to the transfer direction in an exit. In these drawings, the same components as those shown in FIGS. 1 to 9 are denoted by the same reference numerals.

  The basic structure of the mass transfer device 210 of the third embodiment is the same as that of the mass transfer device 110 of the second embodiment. The difference from the mass transfer device 110 is that the interval between the blades and the second blade 252 are formed. is there. The distance (interval) d between the surfaces facing each other of the blades 250 of the mass transfer device 210 of the third embodiment is longer as it goes to the outlet 14 (see FIG. 2 and the like), as in the mass transfer device 110 of the second embodiment. However, the distance d in the vicinity of the outlet 14 is longer for the blade 250 than for the blade 150. Specifically, the distance d in the vicinity of the inlet 12 (see FIG. 2 etc.) is 2.5 cm, the distance d5 in the vicinity of the outlet 14 is 7.45 cm, and during this time, the distance d2 to d5 is set for each turn of the blade 250. Increased to 3.0 cm, 3.75 cm, 4.75 cm.

  In this way, by increasing the distances d, d2, d3, d4, and d5 from the inlet 12 to the outlet 14, the cross section (surface perpendicular to the transfer direction) of the transfer path 260 becomes wider toward the outlet 14. In the vicinity of the outlet 14, the distance d5 becomes too long, and the substance tends to stay in the transfer path 260, so that turbulent flow is likely to occur. In order to prevent the occurrence of this turbulent flow, the second blade 252 was formed.

  As shown in FIG. 9, the second blade 252 has an outer peripheral surface of the rotating member 30 so as not to contact the blade 250 from between the surfaces of the blade 250 facing each other (here, between the blades having a distance d4). 31 is spirally extended. Specifically, the second blade 252 starts to be formed from the position opposite to the start position of the last 1.5 turns of the blade 250 from the position opposite to the outlet 14 via the central shaft 38 (see FIG. 2). Yes. The height at which formation of the second blade 252 starts is low and gradually increases. In the vicinity of the outlet 14, the height of the second blade 252 and the height of the blade 250 are substantially the same. By forming the second blade 252 in this manner, a rectifying action is exerted on the material transferred through the transfer path 260, so that the retention of the material and the generation of turbulent flow due to the distance d of the blade 250 being too wide. Is prevented. Note that the position at which the second blade starts to be formed is determined by an experiment or the like according to the type of substance to be transferred.

  In FIG. 10, the amount transferred by the mass transfer device 210 of the third embodiment, the mass transfer device 110 of the second embodiment, and the mass transfer device 10 of the first embodiment in which the distance d is changed and the second blade 252 is formed is shown. Shown in comparison.

  As shown in FIG. 10, in proportion to the number of rotations (rpm), the mass transfer devices 10 and 110 of Examples 1 and 2 and the material transfer device 210 of Example 3 increase in flow rate, but with an increase in the number of rotations. Among these, the mass transfer device 210 has the largest increase rate of the flow rate. This is because, as described above, the cross section of the transfer path 260 (the plane orthogonal to the transfer direction) is widened so that a larger amount of material can be transferred and a laminar flow is formed by the second blade 252. This is because a force (negative pressure) acts to suck the substance put in from the inlet 12 into the back of the transfer path 260 (toward the outlet 14). In addition, since turbulent flow does not occur, there is no damage to the transferred material.

  With reference to FIG. 11 and FIG. 12, Example 4 of the substance transfer apparatus of this invention is demonstrated.

FIG. 11 is a side view illustrating a rotating member and blades of the substance transfer device according to the fourth embodiment. FIG. 12 is a graph showing a comparison of the transfer amounts by the substance transfer device of Example 4 and the substance transfer devices of Examples 1, 2, and 3. The horizontal axis represents the number of rotations (rpm) of the rotating member, and the vertical axis An axis | shaft represents the transfer amount (L / min (liter per minute)) per 1 cm < ² > of the surface orthogonal to the transfer direction in an exit. In these drawings, the same components as those shown in FIGS. 1 to 10 are denoted by the same reference numerals.

  The basic structure of the mass transfer device 310 of the fourth embodiment is the same as that of the mass transfer device 10 of the first embodiment. The difference from the mass transfer device 10 is that the thickness t of the blade is closer to the outlet 14 ( The closer to the entrance 12, the thinner). The thickness t of the blade 350 of the mass transfer device 310 of Example 4 is 2.0 mm in the vicinity of the inlet 12 (see FIG. 2 and the like), and 5.0 mm in the vicinity of the outlet 14. Then, the thickness t was increased by about 0.5 mm for each turn of the blade 350. The thickness of the blade 350 is set to a thickness that does not reduce the width (d to d5) of the flow path.

  Thus, by gradually increasing the thickness t of the blade 350 from the inlet 12 toward the outlet 14, the blade 350 becomes thicker in a region where the transfer speed is high, and thus the durability of the blade 350 is improved. In addition, since the blade 350 is thin in the vicinity of the inlet 12 (region where the transfer speed is low), the material put in from the inlet 12 is less likely to collide with the blade 350, and the damage to the material is reduced. Moreover, the resistance to the transfer of the substance is reduced, and the substance is transferred smoothly.

  In FIG. 12, the transfer amount by the substance transfer apparatus 310 of Example 4 and the substance transfer apparatuses 10, 110, and 210 of Examples 1, 2, and 3 is compared and shown.

  As shown in FIG. 12, the flow rate of each substance transfer device 10, 110, 210, 310 increases in proportion to the number of rotations (rpm). The transfer device 210 is the largest.

  With reference to FIG. 13 and FIG. 14, Example 5 of the substance transfer apparatus of this invention is demonstrated.

FIG. 13 is a side view illustrating a rotating member and blades of the substance transfer device according to the fifth embodiment. FIG. 14 is a graph showing a comparison of the amount transferred by the substance transfer apparatus of Example 5 and the substance transfer apparatus of Example 1, in which the horizontal axis represents the number of rotations (rpm) of the rotating member, and the vertical axis represents the outlet. It represents the transfer amount per 1 cm ^{2 of} the surface perpendicular to the transfer direction (L / min (liter per minute)). In these drawings, the same components as those shown in FIGS. 1 to 12 are denoted by the same reference numerals.

  The basic structure of the mass transfer device 410 of the fifth embodiment is the same as that of the mass transfer device 10 of the first embodiment. The difference from the mass transfer device 10 of the first embodiment is the boundary between the blade 450 and the outer peripheral surface 31. When the tangent line 52 is translated toward the center line (straight line) 36 (center axis 38) and the tangent line 52 intersects the center line 36, the inclination angle θ formed by the tangent line 52 and the center line 36 is The closer it is, the smaller it is. This inclination angle θ is experimentally determined according to the type of substance to be transferred and the size of the solid matter. Here, two examples in which the tilt angle θ is changed are shown in FIG. 14, and the relationship between the tilt angle θ and the flow rate (transfer amount) will be described.

  A straight line I in FIG. 14 represents the flow rate in the case of Example 1 (the material transfer device 10), and the inclination angles θ1 to θ3 are 84 ° in any part of the blade 50. In the straight line II of FIG. 14, the inclination angle θ1 of the portion closest to the inlet 12 of the blades 450 is 85 °, the inclination angle θ2 of the central portion is 82 °, and the inclination angle θ3 of the portion closest to the outlet 14 is 75 °. Represents the flow rate. A straight line III in FIG. 14 indicates that the inclination angle θ1 of the portion closest to the inlet 12 of the blades 450 is 77 °, the inclination angle θ2 of the central portion is 73 °, and the inclination angle θ3 of the portion closest to the outlet 14 is 55 °. Represents the flow rate.

  According to the above experiment, the inclination angle θ1 of the portion closest to the inlet 12 of the blades 450 is set to 85 °, the inclination angle is gradually decreased toward the outlet 14, and the inclination angle θ3 of the portion closest to the outlet 14 is set. It was found that the flow rate was highest when the angle was 75 °. The reason for this is that the smaller the inclination angle θ, the higher the transfer speed of the substance being transferred (peripheral speed of the outer peripheral surface 31) (because the acceleration of the substance increases). If the inclination angle θ is too small, the acceleration increases, and the material being transferred is easily damaged.

  As an example of the transferred substance, water was used as a fluid, and fragile solids such as boiled potatoes, carrots, radishes, rice grains, and bean grains having a size of about 10 mm were used. It was discharged from the exit while keeping In addition, the medaka that lived with water was transported, but it was discharged from the exit alive.

  With reference to FIG. 15 and FIG. 16, Example 6 of the substance transfer apparatus of this invention is demonstrated.

FIG. 15A is a side view showing the substance transfer device of Example 6, and FIG. 15B is a sectional view showing a part of FIG. FIG. 16 is a graph showing a comparison of the amounts transferred by the substance transfer device of Example 6 and the substance transfer device of Example 1, in which the horizontal axis represents the number of rotations (rpm) of the rotating member, and the vertical axis represents the outlet. It represents the transfer amount per 1 cm ^{2 of} the surface perpendicular to the transfer direction (L / min (liter per minute)). In these drawings, the same components as those shown in FIGS. 1 to 14 are denoted by the same reference numerals.

  The basic structure of the mass transfer device 510 of the sixth embodiment is the same as that of the mass transfer device 10 of the first embodiment. The difference from the mass transfer device 10 of the first embodiment is that the portion of the blade 50 close to the outlet 14. The point is that a shielding wall (lid) 552 is arranged. The shielding wall (lid) 552 shields the outer peripheral surface 31 of the rotating member 30 from the inner peripheral surface 24 of the housing 20, and spreads between the tips (top surfaces) of portions facing each other of the blades 50. It extends parallel to the surface 31 (spreads). Although the shielding wall 552 may be disposed in all parts of the blade 50, the shielding wall 552 becomes an obstacle when the mass transfer device 510 is cleaned.

  In the portion where the shielding wall 552 is formed as described above, since the substance being transferred does not contact the inner peripheral surface 24 (fixed) of the housing 20, the substance being transferred and the inner peripheral face 24 are not in contact with each other. Friction can be eliminated and materials can be transferred smoothly.

  FIG. 16 shows an example in which the flow rate is compared depending on the presence or absence of the shielding wall 552. It was found that the mass transfer device 510 provided with the shielding wall 552 has an increased flow rate compared to the material transfer device 10 (Example 1) without the shielding wall 552.

  With reference to FIG. 17 and FIG. 18, Example 7 of the mass transfer apparatus of this invention is demonstrated.

FIG. 17 is a side view illustrating the substance transfer device according to the seventh embodiment. FIG. 18 is a graph showing a comparison of the amount transferred by the substance transfer apparatus of Example 7 and the substance transfer apparatus of Example 1, in which the horizontal axis represents the number of rotations (rpm) of the rotating member, and the vertical axis represents the outlet. It represents the transfer amount per 1 cm ^{2 of} the surface perpendicular to the transfer direction (L / min (liter per minute)). In these drawings, the same components as those shown in FIGS. 1 to 16 are denoted by the same reference numerals.

  The basic structure of the substance transfer device 610 of the seventh embodiment is the same as the substance transfer device 10 of the first embodiment. The difference from the substance transfer device 10 of the first embodiment is that the outer peripheral surface 31 of the rotating member 30 is the same. The blade 650 is not formed in the vicinity of the entrance. In the substance transfer devices according to the first to sixth embodiments, blades are formed from end to end of the outer peripheral surface 31 of the rotating member 30. In the substance transferring device 610 according to the seventh embodiment, the outer periphery of the rotating member 30 is used. No blade 650 is formed in the vicinity of the entrance of the surface 31. In this case, the resistance by the blades 650 in the vicinity of the inlet decreases, so that the flow rate tends to increase slightly as shown in FIG. Since the material introduced from the inlet 12 does not immediately contact the blades 650, material damage is reduced. Such a substance transfer device 610 is suitable when the solid contained in the substance to be transferred is fragile (easy to be damaged, for example, soft).

  In addition, it is considered that the distance Lx of the portion without the blade 650 described above is preferably within a range where Lx / L1 is 0.5 or less (preferably 0.3 or less).

  With reference to FIG. 19 and FIG. 20, Example 8 of the substance transfer apparatus of this invention is demonstrated.

FIG. 19 is a side view illustrating the substance transfer device according to the eighth embodiment. FIG. 20 (a) is a graph showing a comparison of transfer amounts by the substance transfer device of Example 8 and the substance transfer device of Example 1, and the horizontal axis represents the number of rotations (rpm) of the rotating member, and the vertical axis Represents the transfer amount per 1 cm ^{2 of} the surface orthogonal to the transfer direction at the outlet (L / min (liter per minute)), (b) is a graph showing the pressure at the inlet and outlet, and the horizontal axis is the housing The vertical direction represents the pressure in the water column (m). In these drawings, the same components as those shown in FIGS. 1 to 18 are denoted by the same reference numerals.

  The basic structure of the substance transfer device 710 of the eighth embodiment is the same as that of the substance transfer device 10 of the first embodiment, and the difference from the substance transfer device 10 of the first embodiment is the length of the casing 720 and the rotating member 730. The number of blades 750, 752, and 754 is as follows. A dam plate 735 similar to the dam plate 35 (see FIG. 2) is fixed to the rotating member 730.

  Compared to the substance transfer apparatus 10, the substance transfer apparatus 710 has a casing 720, its internal space 722, and a rotating member 730 that are thick and short. The internal space 722 and the rotating member 730 have a truncated cone shape. The diameter R1 of the bottom surface of the internal space 722 is 20 cm, the diameter R2 of the top surface is 12 cm, and the length L1 is 17.5 cm. The diameter R3 of the bottom surface 734 of the rotating member 730 is 15 cm, and the diameter R4 of the top surface 732 is 7 cm. In addition, on the outer peripheral surface 731 of the rotating member 730, three blades 750, 752 (second blade) and 754 (third blade) that are not continuous (independent) are formed.

  The blade 750 starts to be wound from a portion near the top surface 732 of the outer peripheral surface 731 of the rotating member 730, and is wound to a portion near the bottom surface 734 (wound from end to end). The outer peripheral surface 731 is turned about once until the end of winding (about 360 ° is wound). The second blade 752 starts to be wound from the central portion in the longitudinal direction of the rotating member 730 on the outer peripheral surface 731 of the rotating member 730, and is wound from the beginning to the end of winding. The surface 731 is slightly weakened by about a half circumference (winded at a central angle of about 120 ° to 130 °). The third blade 754 starts to be wound from the central portion in the longitudinal direction of the rotating member 730 on the outer peripheral surface 731 of the rotating member 730, and this position is substantially the same as the winding start position of the second blade 752. However, the central angle is shifted by about 120 °. The third blade 754 is wound up to the middle of the bottom surface 734 and weakens the outer peripheral surface 731 by about a half turn from the start of winding to the end of winding (winded at a central angle of about 120 ° to 130 °). .

  Since the distance d between the surfaces of the blades 750 facing each other is long, as described in the third embodiment, the substance is likely to stay in the transfer path 760 and turbulent flow is likely to occur. This is prevented by the second blade 752 and the third blade 754.

  FIG. 20 shows the flow rate and the pressure difference between the inlet 12 and the outlet 14 when the above-described mass transfer device 710 is used, as compared with the mass transfer device 10 (Example 1). Here, the example which transferred only water is shown. In the present example, the example in which the second blade 752 and the third blade 754 are wound around the outer peripheral surface 731 of the rotating member 730 as described above is shown. You may stagger and roll.

  With reference to FIG. 21 and FIG. 22, Example 9 of the mass transfer apparatus of this invention is demonstrated.

FIG. 21 is a side view illustrating the substance transfer device according to the ninth embodiment. FIG. 22 (a) is a graph showing a comparison of the amount transferred by the substance transfer apparatus of Example 9 and the substance transfer apparatus of Examples 1 to 8, and the horizontal axis represents the rotation speed (rpm) of the rotating member. The vertical axis represents the transfer amount per 1 cm ^{2 of} the surface orthogonal to the transfer direction at the outlet (L / min (liter per minute)), and (b) is a graph showing the pressure at the inlet and the outlet. The axis represents the length direction of the housing, and the vertical axis represents the pressure at the water column (m). In these drawings, the same components as those shown in FIGS. 1 to 20 are denoted by the same reference numerals.

  The substance transfer device 810 according to the ninth embodiment is based on the substance transfer device 10 according to the first embodiment, and the intervals (d, d2, d3, d4, d5) of the blades 850 are gradually increased in the same manner as the substance transfer device 110 according to the second embodiment. Further, a second blade 852 was provided in the same manner as the mass transfer device 210 in Example 3, and a shielding wall 854 was further arranged in the same manner as the mass transfer device 510 in Example 6.

  As shown in FIG. 22, the substance transfer device 810 was found to be superior in terms of transfer amount and pressure as compared to the other substance transfer devices 10, 110, 210, 310, 410, 510, and 610.

  With reference to FIG. 23, Example 10 of the mass transfer apparatus of this invention is described.

  FIG. 23 is a side view illustrating an outline of the substance transfer device according to the tenth embodiment.

  In the substance transfer devices according to the first to ninth embodiments described above, the inlet 12 is formed so that the substance can be introduced from a direction orthogonal to the rotation shaft 38 of the rotating member 30 (an example of a crossing direction). . In the substance transfer device 910 according to the tenth embodiment, the inlet 912 is formed so that the substance can be introduced from a direction parallel to the rotation shaft 938 of the rotating member 930 (arrow IN direction). At the substance outlet 914, the substance is discharged in the direction (arrow OUT direction) orthogonal to the rotation axis 938, as in the first to ninth embodiments.

  The substance transfer device 910 includes an inlet 912 in which a substance is introduced (supplied) from a direction parallel to the rotation axis 938 (arrow IN direction), and a direction in which the substance entered from the inlet 912 is orthogonal to the rotation axis 938 (arrow). A housing (casing) 920 formed with an outlet 914 that is discharged (discharged and discharged) in the OUT direction) is provided. The inlet 12 and outlet 14 have circular cross sections (surfaces orthogonal to the material inflow / outflow direction (directions indicated by arrows IN and OUT)). An internal space 922 is formed in the housing 920, and this internal space 922 extends from the inlet 912 to the outlet 914 while increasing its inner diameter. That is, the internal space 922 gradually expands so that the inner diameter in the vicinity of the inlet 912 is the smallest and the inner diameter in the vicinity of the outlet 914 is the largest. As a shape of the internal space 922, a truncated cone shape is shown in the side view of FIG. 23, but it may be a cone shape. Also, the shape of the internal space 922 may be such that the side view is widened as shown in FIG. 3B, and the side view is like a bullet as shown in FIG. It may be.

The casing 920 has an inner peripheral surface 924 that defines an internal space 922. The inner peripheral surface 924 corresponds to, for example, a frustoconical outer peripheral surface. A flow meter 16 for measuring the flow rate of the substance exiting from the outlet 914 is disposed at the outlet 914. According to this flow meter 16, the transfer amount (L / min (liter per minute)) per 1 cm ² of the cross section of the outlet 914 (the surface orthogonal to the direction in which the substance is put out (arrow OUT direction)) is measured. A pressure gauge 13 that measures the pressure at the inlet 912 is disposed at the inlet 912, and a pressure gauge 15 that measures the pressure at the outlet 914 is disposed at the outlet 914.

  A rotating member 930 that rotates in the internal space 922 is accommodated in the internal space 922 of the housing 920. The rotating member 930 extends from the inlet 912 to the outlet 914 while increasing its outer diameter. The rotating member 930 is preferably similar to the internal space 922, but may not be similar. In the tenth embodiment, since the shape of the internal space 22 is a truncated cone shape, the shape of the rotating member 930 is also a truncated cone shape. However, the top portion (tip portion) 932 of the rotating member 930 has a smooth curved surface so that it is not easily damaged even when a substance put in from the inlet 912 collides.

  The rotating member 930 rotates around a central axis 938 that passes through the top of the smoothly curved top 932 and the center of the circular bottom 934. One end of the central shaft 38 in the longitudinal direction is rotatably fixed to the bearing 942, and a portion of the central shaft 938 that is rotatably fixed to the bearing 942 is connected to the motor 944. When the motor 944 is driven, the rotating member 930 rotates. The motor 944 is controlled by a controller (not shown). The top portion 932 and the bottom surface 934 of the rotating member 930 are configured not to contact the inner wall surface of the housing 920, and the rotating member 930 smoothly rotates without contacting the fixed housing 920. Note that a dam plate 935 similar to the dam plate 35 (see FIG. 2) is fixed (formed) to the rotating member 930.

  Helical blades 950 and 952 are formed on the outer peripheral surface 931 of the rotating member 930, and the blades 950 and 952 rotate together with the rotating member 930.

  The blade 950 spirally extends from a slightly inner side to the rear end (bottom surface 934) of the front end (top portion 932) of the outer peripheral surface 931 of the rotating member 930. In addition, the blade 952 spirally extends from the longitudinal center of the outer peripheral surface 931 to the bottom surface 934 and does not intersect the blade 950. In this way, the effect of the two blades 950 and 952 is the same as in the third embodiment. The cross section of the transfer path 960 (the plane perpendicular to the transfer direction) is widened, so that a larger amount of material can be transferred. Since a laminar flow is formed by the two blades 952, a large amount of material can be smoothly transferred without being damaged.

  In the tenth embodiment, two blades are used, but a single continuous blade may be used as in the first embodiment, and a shielding wall may be formed as in the sixth embodiment. Further, the second blade may not be formed as in the second embodiment, and the blade may be thicker as it approaches the outlet 914 as in the fourth embodiment.

As described above, when the inlet 912 into which the substance is introduced (supplied) from the direction parallel to the rotation axis 938 (the direction of the arrow IN) is formed, the direction in which the substance flows and the outer peripheral surface 931 of the rotating member 930 are substantially parallel. Therefore, the material immediately after entering from the inlet 912 is not easily destroyed. Also,
Since the rotation member 930 can be shortened compared to the case where the inlet is formed so that the substance can be introduced from the direction orthogonal to the rotation shaft 938, it is easy to maintain the equilibrium during the rotation of the rotation shaft 938. In addition, since the support (bearing 942) of the rotating shaft 938 is also provided at one place, maintenance and inspection are easy. Furthermore, the entire material transfer device 910 can be easily assembled and disassembled, and the inside can be easily cleaned.
