Summary of the Invention

Problems to be Solved by the Invention

[0004] In the mixing and grinding apparatus described in Patent Document 1, the outer peripheral portion of the blade member is formed thicker than the inner peripheral portion, and grinding, mixing, and melting are performed efficiently. However, the blade member described in Patent Document 1 may be severely worn depending on the fusion material used. Since the blade member has an integral structure, it takes a lot of cost and time to remove it for each shaft when repairing or replacing the wear. In addition, due to the wear of the blade member, the conditions of the apparatus for grinding, mixing, and melting, as well as the generation conditions of shear and frictional heat, may vary, and there is a risk that the reproducibility during mass production may decrease, and there is a limit to the improvement of productivity. Furthermore, in order to suppress the wear of the blade member, the materials to be used must be restricted.

[0005] In view of the above problems, an object of the present invention is to provide a hybrid melting apparatus capable of efficiently using blade members.

Means for Solving the Problems

[0006] The hybrid melting apparatus of the present embodiment includes a motor that generates a driving force, a rotating shaft rotated by the motor, a spiral supply screw formed on the outer periphery of one side in the axial direction of the rotating shaft, a plurality of blade members formed on the outer periphery of the other side in the axial direction of the rotating shaft, a material input section into which materials are input, a mixing container connected below the material input section, through which the rotating shaft passes, and that pulverizes, mixes, and melts the materials input into the material input section, a fluid supply section that supplies fluid to the material input section or the mixing container, and is provided with.

Embodiments for Carrying Out the Invention

[0009] The mixing and melting apparatus of the present embodiment will be specifically described with reference to the drawings.

[0010] FIG. 1 is a front view showing the mixing and melting apparatus 1 according to an embodiment of the present invention. FIG. 2 is a partially enlarged view showing the blade member 10 and the supply screw 12 in the mixing and melting apparatus 1 of the present embodiment. FIG. 3 is a skeleton block diagram showing the entire system of the mixing and melting apparatus 1 of the present embodiment. In the present embodiment, as shown in FIG. 2, the rotation direction of the rotating shaft 5 is defined as the rotation direction A, the tip of the arrow A is the front side, and the rear end is the rear side. Further, the direction from the upstream to the downstream of the rotating shaft 5 is defined as the rotating shaft direction B, and the upstream and downstream are the directions in which the material moves, and the tip of the arrow B is the downstream and the rear end is the upstream.

[0011] The mixing and melting apparatus 1 of the present embodiment includes a machine base 2, a cylindrical mixing container 3 disposed horizontally on the machine base 2, a motor 8 as a drive source installed on the machine base 2, a rotating shaft 5 rotationally driven by the motor 8, a plurality of blade members 10 disposed on the rotating shaft 5 in the mixing container 3, a material input section 14 for inputting the material, and a supply screw 12 for supplying the material input into the material input section 14 to the mixing container 3. The material input section 14 has an upper hopper 14a and a material inflow section 14b at a position sandwiching the opening / closing section 15 below the hopper 14a.

[0012] The motor 8 is driven by a power source (not shown). The motor 8 transmits the driving force to the rotating shaft 5, and rotates the blade member 10 and the supply screw 12 via the rotating shaft 5. The motor 8 can control the rotational speed within a range where the tip peripheral speed of the blade member 10 is between 5 m / s and 50 m / s. Also, the output shaft of the motor 8 and the rotating shaft 5 are connected by a V-belt 7 that can slip so that when a sudden change in load torque occurs in the rotating shaft 5, the load torque is not transmitted to the motor 8. Note that the output shaft of the motor 8 and the rotating shaft 5 may be connected via a brake or a clutch or the like. Also, the rotating shaft 5 may be formed coaxially with the output shaft of the motor 8.

[0013] The rotating shaft 5 is horizontally supported by bearings 4, 4 and is inserted through the center of the mixing container 3 coaxially. One end of the rotating shaft 5 is rotationally connected to a motor 8 as a driving source via a pulley 6 and a V-belt 7. The rotating shaft 5 is hollow with a small-diameter hole for supplying cooling water formed in its axial center portion, and rotary joints 9 are provided at both ends thereof, and the cooling water is configured to be supplied axially into the rotating shaft 5 through the rotary joints 9.

[0014] On the outer periphery of the rotating shaft 5 disposed through the mixing container 3, as shown in FIG. 2, a total of six blade members 10a to 10f having a rectangular cross-sectional shape and a rectangular overall shape are projected axially at an angular interval of 180 degrees in the circumferential direction of the rotating shaft 5 with a space therebetween. As shown in FIG. 2, the thickness of the blade members 10a to 10f is formed such that approximately 40% of the outer peripheral side portion is thicker than the inner peripheral side, and the mixing, pulverization, and melting of the material are configured to be effectively performed. Note that the outer peripheral side of the blade member 10 may not be formed thicker, and the inner peripheral side and the outer peripheral side may be formed with the same width and thickness.

[0015] Of these, the blade members 10a and 10f at both axial ends are fixed to the outer periphery of the rotating shaft 5 inclined at an attachment angle of about 15 degrees from the tip to the root of the blade member 10 so that when rotating in the clockwise rotation direction A when viewed from the right side surface of FIG. 2, the front edge thereof is in almost sliding contact with the inner surfaces of the vertical walls 11, 11 at both ends of the mixing container 3 with almost no gap.

[0016] Also, the four blade members 10b, 10c, 10d, and 10e in the middle part are fixed to the outer peripheral surface of the rotating shaft 5 in a stagger pattern, inclined from the tip to the root of each blade, and are respectively arranged in a direction where the leading edge during rotation faces both ends of the mixing container 3. That is, the four blade members 10b and 10d, 10c and 10e are arranged on the rotating shaft 5 at an attachment angle (angle with respect to the circumferential direction) of 15 degrees such that they face each other in the axial direction and the opposing interval between them narrows in the rotational direction, as shown in FIG. 2.

[0017] Also, in the direction of the rotating shaft 5, the motor 8 side of the mixing container 3 is the material supply part 3a, and the opposite side of the motor 8 is the material mixing part 3b. Inside the material supply part 3a, a spiral supply screw 12 formed on the outer periphery of the rotating shaft 5 is housed. The material supply part 3a surrounds the supply screw 12. Above the material supply part 3a, a material input part 14 is provided. After the material is input into the material input part 14, an openable and closable opening / closing part 15 that can be hermetically closed during mixing, pulverizing, and melting is provided. Also, on both sides of the blade member 10 and the supply screw 12 of the rotating shaft 5, a pair of balance wheels 16 for obtaining smooth rotation are installed.

[0018] The material mixing part 3b surrounds the blade member 10 fixed to the rotating shaft 5. The material mixing part 3b has the material supply part 3a on the upstream side. The material input into the material supply part 3a is moved to the material mixing part 3b by the supply screw 12 inside the material supply part 3a. The material is mixed by the blade member 10 in the material mixing part 3b. Note that the material may be input from above the material mixing part 3b without using the material supply part 3a and the supply screw 12.

[0019] As shown in FIG. 3, a continuous water passage 24 is formed in the peripheral wall of the mixing container 3 and at the center of the rotating shaft 5, and a cooling part 22 that can cool the peripheral wall of the mixing container 3 and the rotating shaft 5 by circulating cooling water is configured. The cooling part 22 cools water by a cooling tower 23, cools the mixing container 3, the rotating shaft 5, etc. as cooling water, and returns to the cooling tower 23.

[0020] Further, a discharge port cover 17 for taking out the melted material is provided on the bottom wall portion of the mixing container 3. The discharge port cover 17 is rotatably supported by a shaft 18, and the shaft 18 is connected to rotary cylinders 19, 19 and is configured to be openable and closable.

[0021] Also, the both-side collars 20, 20 shown in FIG. 3 are for sending air into the mixing container 3, and each continuous groove at both ends is composed of a right-handed screw groove and a left-handed screw groove so that air is sent into the mixing container 3 by the rotation of the rotary shaft 5.

[0022] Further, the control panel 21 is connected via a connection cable to the motor 8, and the load torque of the main shaft is continuously input from the motor 8 as an electric signal. The control panel 21 may control the opening and closing timing of the discharge port cover 17 of the mixing container 3 based on the change in the load torque acting on the main shaft of the motor 8 according to the mixing, pulverizing, and drying state of the material in the mixing container 3, so as to take out the mixed and pulverized material.

[0023] A method for manufacturing a fusion material will be described by the mixing and melting apparatus 1 as the mixing and melting apparatus of the present embodiment. The user puts a material into the mixing container 3 of the mixing and melting apparatus 1 through an opening (not shown), drives the motor 8, rotates the rotary shaft 5, the blade member 10, and the supply screw 12, and finely pulverizes the material. The size of the pulverized particles is preferably about 2 to 7 mm. Note that the pulverizing step is not performed when only a material that has been previously pulverized by another apparatus is put in.

[0024] Subsequently, the motor 8 is driven, the rotary shaft 5, the blade member 10, and the supply screw 12 are rotated, and the pulverized materials are mixed. The rotation speed of the rotary shaft 5 is preferably 500 rpm or more.

[0025] Also, in the production of the fusion material of the present embodiment, additives for compatibilization or the like may not be used. By not using additives or the like, environmental performance is improved. Further, in the present embodiment, it is preferable to supply a fluid to the material by the fluid supply unit 30. By supplying the fluid, the internal pressure can be increased in a subsequent process. The fluid may be supplied in advance into the mixing container 3, or may be supplied into the mixing container 3 during operation. Here, as the fluid, air, tap water, cold water, warm water, or hot water is used. Therefore, the mixing and melting apparatus 1 of the present embodiment can appropriately adjust the pressure, temperature, humidity, etc. inside the mixing container 3. Also, for example, when air or tap water is used, it can be operated at low cost, when cold water is used, the inside of the mixing container 3 can be cooled, and when warm water or hot water is used, the inside of the mixing container 3 can be heated.

[0026] Subsequently, drive the motor 8 to rotate the rotating shaft 5, the blade member 10, and the supply screw 12. When the blade member 10 is rotated at high speed, the inside of the mixing container 3 becomes a high temperature of 100 ° C. or higher due to the movement of the material itself and the friction caused by the materials colliding and shearing each other. Then, steam is generated from the fluid, pressure is applied inside the mixing container 3, and each material melts.

[0027] Subsequently, drive the motor 8 to rotate the rotating shaft 5, the blade member 10, and the supply screw 12 to advance the reaction of the materials. As the reaction progresses, the materials integrate. At the same time, the fluid vaporizes into steam and is discharged outside from a discharge port (not shown) of the mixing container 3. Therefore, the inside of the mixing container 3 is dried, and a fusion product from which moisture and the like have been removed is obtained.

[0028] The obtained fusion product is a new material in which a plurality of materials having different melting points are uniformly fused at the molecular level, and since it can be molded by injection, extrusion, blow molding, pressing, etc., it can be used for various applications.

[0029] In addition, the method for manufacturing the fusion material of the present embodiment is executed in less than 1800 seconds. Generally, the more heat is applied to the material, the more severely it deteriorates. The method for manufacturing the fusion material of the present embodiment does not apply heat from the outside, and the time during which heat is applied to the material is short. Therefore, the fusion material manufactured by the method for manufacturing the fusion material of the present embodiment has less deterioration and can retain its strength. In addition, since the fusion material manufactured by the method for manufacturing the fusion material of the present embodiment has less deterioration, the completed fusion can also be reused.

[0030] Next, the blade member 10 of the present embodiment will be described. In the following description of the blade member 10 of the present embodiment, for ease of understanding, the rotational direction A and the rotational axis direction B are defined as shown in the drawings. However, in reality, as shown in FIG. 2, the blade member 10 is inclined with respect to the rotational direction A and the rotational axis direction B.

[0031] FIG. 4 shows a three-view drawing of the blade member 10 of the mixing and melting apparatus 1 of the first embodiment. FIG. 4(a) is a view seen from the opposite side of the rotational axis direction B, FIG. 4(b) is a view seen from the left side of FIG. 4(a), and FIG. 4(c) is a view seen from the left side of FIG. 4(a). FIG. 5 shows an assembly drawing of the blade member 10 of the mixing and melting apparatus 1 of the first embodiment.

[0032] The blade member 10 of the first embodiment includes a blade base portion 100 disposed on the rotational shaft 5, a blade tip portion 101 removably attached to the blade base portion 100, and a bolt 102 as a holding portion for attaching the blade tip portion 101 to the blade base portion 100.

[0033] The blade base portion 100 is fixed to the rotational shaft 5 by welding or the like. On the front side in the rotational direction A at the tip of the blade base portion 100 (the right side of the paper surface in FIG. 4(a)), a guide portion 100a having a T-shaped concave shape in a cross section orthogonal to the rotational shaft 5 is formed. The portion of the guide portion 100a that hits the upper horizontal bar of the T shape is formed on the rotational shaft 5 side. A first screw hole 100b is formed on the rear side in the rotational direction A of the guide portion 100a (the left side of the paper surface in FIG. 4(a)). The first screw hole 100b has a diameter-expanded hole portion 100b1 for accommodating the head 102a of the bolt 102.

[0034] The blade tip portion 101 is detachably attached to the tip on the side opposite to the rotation axis 5 of the blade base portion 100. The blade tip portion 101 includes a tip body 101a that contacts the material, and a protrusion 101b that is guided by the guide portion 100a when detaching from the blade base portion 100. The tip body 101a has a rectangular parallelepiped shape, is longer in width parallel to the rotation direction A than the blade base portion 100, and is thicker in thickness in the rotation axis direction B. The protrusion 101b protrudes in a T shape in a cross section orthogonal to the rotation axis 5 from the tip body 101a. A second screw hole 101b1 is formed on the rear side of the protrusion 101b in the rotation direction A.

[0035] In the blade member 10 of the first embodiment, as shown in FIG. 5, the blade tip portion 101 is attached to the blade base portion 100. First, the user inserts the protrusion 101b of the blade tip portion 101 into the guide portion 100a of the blade base portion 100. Subsequently, the user moves the blade tip portion 101 in the direction of arrow C. The protrusion 101b is fitted until it abuts against the wall portion 100a1 where the first screw hole 100b of the guide portion 100a is formed. Subsequently, the user screws the bolt 102 into the first screw hole 100b and the second screw hole 101b1 from the direction of arrow D.

[0036] In the blade member 10 of the first embodiment, by moving in the direction opposite to the arrow C in FIG. 5, the blade tip portion 101 is removed from the blade base portion 100. First, the user removes the bolt 102 from the first screw hole 100b and the second screw hole 101b1 in the direction opposite to the arrow D. Subsequently, the user moves the blade tip portion 101 in the direction opposite to the arrow C and removes the protrusion 101b of the blade tip portion 101 from the guide portion 100a of the blade base portion 100.

[0037] As described above, since the blade member 10 of the first embodiment has a structure in which the blade tip portion 101 is detachable from the blade base portion 100, it is not necessary to remove each shaft during repair or replacement due to wear, and costs and time can be saved. Further, by immediately replacing the blade member 10, the mixing and melting apparatus 1 does not experience fluctuations in the conditions of pulverization, mixing, and melting, or the generation conditions of shear and frictional heat, and the reproducibility during mass production does not decrease. Furthermore, there is no need to limit the materials used in order to suppress wear of the blade member 10.

[0038] FIG. 6 shows a perspective view of the blade member 10 of the mixing and melting apparatus 1 according to the second embodiment. FIG. 6(a) is a view seen from the side opposite to the rotational axis direction B, FIG. 6(b) is a view seen from the left side of FIG. 6(a), FIG. 6(c) is a view seen from the left side of FIG. 6(a), and FIG. 6(d) is a view seen from the blade tip side. FIG. 7 shows an assembly view of the blade member 10 of the mixing and melting apparatus 1 according to the second embodiment.

[0039] The blade member 10 of the second embodiment includes a blade base portion 100 disposed on the rotating shaft 5, a blade tip portion 101 detachably attached to the blade base portion 100, and a bolt 102 as a holding portion for attaching the blade tip portion 101 to the blade base portion 100.

[0040] The blade base portion 100 is fixed to the rotating shaft 5 by welding or the like. A notch is formed on the front side (the right side of the drawing in FIG. 6(a)) in the rotational direction A at the tip of the blade base portion 100. On the blade base portion 100 on the rotating shaft 5 side of the notch, a guide portion 100a having a T-shaped concave shape in a cross section perpendicular to the rotating shaft 5 is formed. The portion of the guide portion 100a that hits the upper horizontal bar of the T shape is formed on the rotating shaft 5 side. Further, a fitting recess 100c is formed in the rotating base portion 100 on the rear side in the rotational direction A of the notch. The fitting recess 100c may be a rectangular parallelepiped-shaped hole. A first screw hole 100b is formed on the tip side of the fitting recess 100c. The first screw hole 100b penetrates from the tip of the blade base portion 100 to the fitting recess 100, and has a diameter-expanded hole portion 100b1 at the tip for accommodating the head 102a of the bolt 102.

[0041] The blade tip portion 101 is removably attached to a notch formed on the side opposite to the rotation axis 5 of the blade base portion 100 and on the front side in the rotation direction A. The blade tip portion 101 includes a tip body 101a that contacts the material, a protrusion 101b that is guided by the guide portion 100a when removing the blade tip portion 101 from the blade base portion 100, and a fitting protrusion 101c that is fitted into the fitting recess 100c when removing the blade tip portion 101 from the blade base portion 100. The tip body 101a has a rectangular parallelepiped shape and is formed flush with the blade base portion 100. Note that the tip body 101a may protrude in the front and rear in the rotation direction A from the blade base portion 100, and may be thicker in the thickness direction B of the rotation axis. The protrusion 101b protrudes in a T shape in a cross section perpendicular to the rotation axis 5 from the tip body 101a toward the rotation axis 5 side. A second screw hole 101c1 is formed on the tip side of the fitting protrusion 101c.

[0042] In the blade member 10 of the second embodiment, as shown in FIG. 7, the blade tip portion 101 is attached to the blade base portion 100. First, the user inserts the protrusion 101b of the blade tip portion 101 into the guide portion 100a of the blade base portion 100. Subsequently, the user moves the blade tip portion 101 in the direction of arrow E. When the protrusion 101b is guided by the guide portion 100A, the fitting protrusion 101c is fitted into the fitting recess 100c. Subsequently, the user screws the bolt 102 into the first screw hole 100b and the second screw hole 101c from the direction of arrow F.

[0043] In the blade member 10 of the second embodiment, by moving in the reverse direction of the arrow in FIG. 7, the blade tip portion 101 is removed from the blade base portion 100. First, the user moves the bolt 102 in the reverse direction of arrow F and removes it from the first screw hole 100b and the second screw hole 101c. Subsequently, the user moves the blade tip portion 101 in the reverse direction of arrow E and removes the protrusion 101b of the blade tip portion 101 from the guide portion 100a of the blade base portion 100.

[0044] Thus, since the blade member 10 of the second embodiment has a structure in which the blade tip portion 101 is detachable from the blade base portion 100, it is not necessary to remove each shaft during repair or replacement of wear, and costs and time can be saved. Further, by forming the replaceable blade tip portion 101 small, costs and time at the time of replacement can be further saved. Further, by immediately replacing the blade member 10, the melt-blending apparatus 1 does not experience fluctuations in the conditions of pulverization, mixing, and melting, or the generation conditions of shear and frictional heat, and the reproducibility during mass production does not decrease. Furthermore, in order to suppress wear of the blade member 10, it is not necessary to limit the materials used.

[0045] FIG. 8 shows a perspective view of the blade member 10 of the melt-blending apparatus 1 according to the third embodiment. FIG. 8(a) is a view seen from the side opposite to the rotational axis direction B, FIG. 8(b) is a view seen from the left side of FIG. 8(a), FIG. 8(c) is a view seen from the left side of FIG. 8(a), and FIG. 8(d) is a view seen from the blade tip side. FIG. 9 shows an assembly view of the blade member 10 of the melt-blending apparatus 1 according to the third embodiment.

[0046] The blade member 10 of the third embodiment includes a blade base portion 100 disposed on the rotary shaft 5, a blade tip portion 101 detachably attached to the blade base portion 100, and a bolt 102 serving as a holding portion for attaching the blade tip portion 101 to the blade base portion 100.

[0047] The blade base portion 100 is fixed to the rotary shaft 5 by welding or the like. Notches are formed on the front side in the rotational direction A (the right side of the paper surface in FIG. 8(a)), the downstream side in the rotational axis direction B, and the tip side of the tip of the blade base portion 100. On the blade base portion 100 on the rear side of the notch in the rotational axis direction B, a guide portion 100a having a trapezoidal concave shape in a cross section parallel to the rotational axis direction B is formed. The portion of the guide portion 100a that hits the bottom of the trapezoid is formed on the rear side in the rotational axis direction B. A first screw hole 100b is formed in at least one of the blade base portion 100 on the rear side of the notch in the rotational axis direction B and the rear side in the rotational axis direction B (the right side of the paper surface in FIG. 8(c)) of the blade base portion 100 guide portion 100a.

[0048] The blade tip portion 101 is detachably attached to the front side (the right side of the paper surface in Fig. 8(a)) in the rotational direction A opposite to the rotation axis 5 of the blade base portion 100, the downstream side in the rotation axis direction B, and the tip. The blade tip portion 101 includes a tip portion main body 101a that contacts the material, a trapezoidal protruding portion 101b that is guided by the guide portion 100a when detaching from the blade base portion 100, and a tip protruding portion 101d that protrudes in an L shape from the tip of the tip portion main body 101a. The tip portion main body 101a is formed as a planar rectangular parallelepiped. The protruding portion 101b protrudes trapezoidally from the tip portion main body 101a. The tip protruding portion 101d is formed as a plate-shaped rectangular parallelepiped and protrudes in the same direction as the protruding portion 101b from the tip of the tip portion main body 101a. A second screw hole 101a1 is formed in the tip portion main body 101a and the protruding portion 101b. The second screw hole 101a1 has a diameter-expanded hole portion 101a2 for accommodating the head 102a of the bolt 102.

[0049] In the blade member 10 of the third embodiment, as shown in Fig. 9, the blade tip portion 101 is attached to the blade base portion 100. First, the user inserts the protruding portion 101b of the blade tip portion 101 into the guide portion 100a of the blade base portion 100. Subsequently, the user moves the blade tip portion 101 in the direction of arrow G. The protruding portion 101b is fitted until it abuts against the wall portion 100a1 of the guide portion 100a. Subsequently, the user screws the bolt 102 into the second screw hole 101b1 and the first screw hole 100b from the direction of arrow H.

[0050] In the blade member 10 of the third embodiment, by moving in the reverse direction of the arrow in Fig. 9, the blade tip portion 101 is removed from the blade base portion 100. First, the user removes the bolt 102 from the first screw hole 100b and the second screw hole 101b1 in the reverse direction of arrow H. Subsequently, the user moves the blade tip portion 101 in the reverse direction of arrow G and removes the protruding portion 101b of the blade tip portion 101 from the guide portion 100a of the blade base portion 100.

[0051] Thus, since the blade member 10 of the third embodiment has a structure in which the blade tip portion 101 is detachable from the blade base portion 100, it is not necessary to remove each shaft during repair or replacement of wear, and costs and time can be saved. In addition, by forming the replaceable blade tip portion 101 small, costs and time during replacement can be saved even more. Further, by immediately replacing the blade member 10, the melting and mixing apparatus 1 does not experience fluctuations in the conditions of pulverization, mixing, and melting, or in the generation conditions of shear and frictional heat, and the reproducibility during mass production does not decrease. Furthermore, in order to suppress wear of the blade member 10, it is not necessary to limit the materials used.

[0052] In this embodiment, the blade base portion 100 has a concave guide portion 100a, and the blade tip portion 111 has a protruding portion 101b guided by the guide portion 100a. However, the present invention is not limited to this, and a configuration may be adopted in which one of the blade base portion 100 or the blade tip portion 111 has a concave guide portion 100a, and the other of the blade base portion 100 or the blade tip portion 111 has a protruding portion 101b guided by the guide portion 100a.

[0053] The shapes of the protruding portion 101b and the guide portion 100a are not limited to a T-shaped cross section or a trapezoidal cross section, and other shapes may be used. The positions of the protruding portion 101b and the guide portion 100a may be anywhere, and the number of the protruding portion 101b and the guide portion 100a may be any number.

[0054] The blade tip portion 101 of the present embodiment is preferably manufactured from a plurality of materials having different hardnesses so that it can be selected based on the hardness of the material. The material of the blade tip portion 101 may be selected according to the hardness of the material. For example, for a resin material, a material having a Mohs hardness of 5 or more, such as steel, may be used. For a harder material, a harder material may be selected and used.

[0055] As described above, the mixing and melting apparatus 1 of the present embodiment includes a motor 8 that generates a driving force, a rotating shaft 5 that rotates by the motor 8, a plurality of blade members 10 formed on the outer periphery on the other side in the axial direction of the rotating shaft 5, a material input section 14 into which a material is input, and a mixing container 3 that is connected below the material input section 14, through which the rotating shaft 5 passes, and that mixes and melts the material input into the material input section 14. The blade member 10 has a blade base portion 100 disposed on the rotating shaft 5 and a blade tip portion 101 removably attached to the blade base portion 100.

[0056] Therefore, in the mixing and melting apparatus 1 of the present embodiment, since the blade tip portion 101 of the blade member 10 is detachable from the blade base portion 100, it is not necessary to remove each shaft during repair or replacement due to wear, and costs and time can be saved. Further, by immediately replacing the blade member 10, the mixing and melting apparatus 1 does not experience a decrease in reproducibility during mass production without fluctuations in the conditions of pulverization, mixing, and melting or the generation conditions of shear and frictional heat. Furthermore, it is not necessary to limit the materials used in order to suppress wear of the blade member 10.

[0057] Also, in the mixing and melting apparatus 1 of the present embodiment, the blade member 10 has a holding portion 102 for attaching the blade base portion 100 and the blade tip portion 101. Therefore, in the mixing and melting apparatus 1 of the present embodiment, the blade base portion 100 and the blade tip portion 101 can be appropriately attached.

[0058] Also, in the mixing and melting apparatus 1 of the present embodiment, one of the blade base portion 100 or the blade tip portion 101 has a concave guide portion 100a, and the other of the blade base portion 100 or the blade tip portion 101 has a protruding portion 101b guided by the guide portion 100a. Therefore, in the mixing and melting apparatus 1 of the present embodiment, the blade tip portion 101 can be smoothly replaced.

[0059] In addition, in the mixing and melting apparatus 1 of the present embodiment, when the rotation direction of the rotating shaft 5 is the rotation direction A and the direction in which the material moves from the upstream to the downstream of the rotating shaft 5 is the rotating shaft direction B, a notch is formed on the front side in the rotation direction A at the tip of the blade base 100, and the blade tip portion 101 fits into the notch. Therefore, the mixing and melting apparatus 1 of the present embodiment can save more cost and time during replacement by forming the replaceable blade tip portion 101 to be small. In addition, the material can be appropriately brought into contact with the replaceable blade tip portion 101.

[0060] In addition, in the mixing and melting apparatus 1 of the present embodiment, when the rotation direction of the rotating shaft 5 is the rotation direction A and the direction in which the material moves from the upstream to the downstream of the rotating shaft 5 is the rotating shaft direction B, a notch is formed on the front side in the rotation direction A, the downstream side, and the tip side in the rotating shaft direction B at the tip of the blade base 100, and the blade tip portion 101 fits into the notch. Therefore, the mixing and melting apparatus 1 of the present embodiment can save more cost and time during replacement by forming the replaceable blade tip portion 101 to be small. In addition, the material can be appropriately brought into contact with the replaceable blade tip portion 101.

[0061] The present invention is not limited to the above-described embodiments, and various modifications can be made and implemented without departing from the gist of the present invention. And all of them are included in the technical idea of the present invention.
