Description

[Technical Field]

[0001] The present invention relates to a drying device. [Background technology]

[0002] Conventionally, conical dryers for drying materials to be dried have been known (for example, Patent Document 1, etc.). In Patent Document 1, a glass lining or the like is applied to the inner surface of the inner container of a double-cone structure main body, thereby enabling the drying and uniform mixing of corrosive materials. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-65674 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in Patent Document 1, the main body is rotatably supported by bearings provided on both sides of the main body, which requires space to provide the bearings on both sides of the main body, resulting in a problem of a large space being required to place the conical dryer.

[0005] An object of the present invention is to provide a drying device that can be installed in a small space. [Means for solving the problem]

[0006] The drying device of the present invention is characterized by comprising a main body portion in which the object to be dried is accommodated, a stand portion that rotatably supports the main body portion in a cantilevered manner, and a drive portion that rotates the main body portion.

[0007] In the present invention, the stand that rotatably supports the main body is configured to support the main body in a cantilevered manner, so that the bearings need only be provided on one side of the main body, which reduces the space required for arranging the drying device compared to when bearings are provided on both sides of the main body.

[0008] In the drying device of the present invention, it is preferable that the main body has a window on a surface opposite to a surface supported by the stand. In this configuration, the main body has a window, through which the objects to be dried housed in the main body can be checked. In this case, the window is provided on the surface of the main body opposite to the surface supported by the stand, so that the operator can avoid interference with the stand when checking the objects to be dried through the window.

[0009] In the drying device of the present invention, it is preferable that the inner surface of the main body is glass-lined. In this configuration, the inner surface of the main body is glass-lined, so even if the material to be dried is corrosive, the main body can be prevented from being corroded by the material to be dried.

[0010] In the drying device of the present invention, it is preferable that an outer jacket is provided on the outer periphery of the main body. In this configuration, an outer jacket is provided on the outer periphery of the main body, so the object to be dried can be heated by circulating hot water, steam, or the like as a heat medium between the main body and the outer jacket. [Brief explanation of the drawings]

[0011] [Figure 1] 1 is a front view showing an outline of a drying device according to an embodiment of the present invention; [Figure 2] FIG. 2 is a plan view showing an outline of the drying device according to the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0012] [Embodiment] A drying device 1 according to one embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a front view showing an outline of a drying apparatus 1 of this embodiment, and Fig. 2 is a plan view showing an outline of the drying apparatus 1. Fig. 1 shows a part of a cross section of the drying apparatus 1. In this embodiment, the drying apparatus 1 is configured as an apparatus for drying an object to be dried. As shown in Figures 1 and 2, the drying device 1 includes a main body 2, a stand 3, a drive unit 4, an outer jacket 5, a reduction gear 6, a connection unit 7, a rotating shaft 8, and a rotary joint 9.

[0013] [Main body 2] The main body 2 is made of metal and is configured to be able to accommodate the material to be dried inside. In this embodiment, the main body 2 is cylindrical and tapered so that the diameter becomes smaller toward both ends. That is, both ends of the main body 2 are conical end plates. As a result, the drying apparatus 1 of this embodiment is similar to a conventional double-cone type rotary vacuum dryer in size, but can improve the mixability of the powder or fluid to be dried, thereby enabling the material to be dried to be uniform. An opening on one end of the main body 2 is covered by the first lid 21, and an opening on the other end is covered by the second lid 22. This allows the material to be introduced into the main body 2 through one of the first lid 21 and the second lid 22, and the material to be dried can be removed from the main body 2 through the other of the first lid 21 and the second lid 22. In the state shown in Fig. 1, the material to be dried can be introduced into the main body 2 by opening the first lid 21, and the material can be removed from the main body 2 by opening the second lid 22.

[0014] In this embodiment, the inner surfaces of the main body 2, the first lid 21, and the second lid 22 are glass-lined. This prevents the main body 2, the first lid 21, and the second lid 22 from corroding due to the material to be dried, even if the material is corrosive.

[0015] Furthermore, in this embodiment, the main body 2 is provided with a window 23 on its side. The window 23 is made of a transparent material such as glass. Therefore, an operator using the drying device 1 can check the objects to be dried housed in the main body 2 through the window 23. In this embodiment, the window 23 is provided on the surface of the main body 2 opposite to the surface supported by the stand 3. This prevents interference with the stand 3 when an operator checks the object to be dried through the window 23.

[0016] [Stand 3] The base unit 3 is configured to rotatably support the main body unit 2 in a cantilever manner. In this embodiment, the mount unit 3 includes a base unit 31, a pillar unit 32, a bearing unit 33, and a protruding unit . The base 31 has a rectangular shape in a plan view, and is configured to be fixed to the foundation of the building frame with a chemical anchor (registered trademark) or the like. This makes it possible to prevent the drying device 1 from moving due to centrifugal force or the like while the drying device 1 is in use. The pillar portion 32 has a quadrangular pillar shape and is provided so as to extend vertically from the base portion 31. A bearing portion 33 is provided on the top surface of the pillar portion 32.

[0017] The bearing portion 33 rotatably supports the rotation shaft 8. As will be described later, the rotation shaft 8 is connected to the main body portion 2 via the connection portion 7. The main body 2 is configured to rotate in response to the rotation. Thus, in this embodiment, the pedestal 3 is configured to rotatably support the main body 2 by supporting the rotation shaft 8 with the bearing portion 33. In this embodiment, the stand 3 rotatably supports the main body 2 by one bearing 33. That is, in this embodiment, the stand 3 is configured to cantilever the main body 2. This allows the bearing 33 to be provided only on one side of the main body 2, thereby reducing the space required to arrange the drying device 1 compared to when bearings are provided on both sides of the main body.

[0018] The overhanging portion is provided so as to overhang from the pillar portion 32 on the opposite side to the main body portion 2. In this embodiment, the reduction gear 6 is disposed on the upper portion of the overhanging portion .

[0019] [Driver 4] The drive unit 4 is configured to rotate the main body 2. In this embodiment, the drive unit 4 is configured as a so-called motor. The drive unit 4 is connected to the main body 2 via a reduction gear 6, a rotation shaft 8, and a connection unit 7. As a result, the drive unit 4 is configured to rotate the main body 2 by rotating the motor.

[0020] [Cloak part 5] The mantle 5 is made of metal and has a cylindrical shape, and is provided so as to cover the outer periphery of the main body 2. A flow path 51 is formed between the inner periphery of the mantle 5 and the outer periphery of the main body 2. As will be described later, this embodiment is configured so that the object to be dried housed in the main body 2 can be heated by circulating hot water through the flow path. As a result, the drying device 1 of this embodiment is configured so that the object to be dried can be heated and dried while rotating the main body 2. Therefore, the object to be dried can be dried uniformly.

[0021] [Decelerator 6] The reduction gear device 6 is configured using a so-called speed reducer, and is configured to reduce the rotational power from the drive unit 4 and transmit it to the rotating shaft 8. In this embodiment, the reduction gear device 6 is configured to be able to control the rotation speed of the rotating shaft 8. This makes it possible to obtain sufficient torque for rotating the main body unit 2 via the rotating shaft 8, and to rotate the main body unit 2 at a desired rotation speed.

[0022] [Connection 7] The connection portion 7 is configured to connect the rotation shaft 8 to the side surface of the main body portion 2. As a result, the main body portion 2 is configured to rotate when the rotation shaft 8 rotates. In this embodiment, the connection portion 7 includes a first pipe 71 and a second pipe 72. The first pipe 71 is connected to a hot water inlet pipe 82, which will be described later, and the second pipe 72 is connected to a hot water outlet pipe 83, which will be described later.

[0023] [Rotation axis 8] As described above, the rotating shaft 8 is configured so that the rotational power of the drive unit 4 is transmitted to it via the reduction gear 6. The rotating shaft 8 is connected to the main body 2 via the connection part 7. As a result, as described above, the main body 2 is configured to rotate when the rotating shaft 8 rotates due to the power of the drive unit 4. In this embodiment, the rotary shaft 8 includes a vacuum pipe 81, a hot water inlet pipe 82, and a hot water outlet pipe 83 therein.

[0024] The vacuum pipe 81 is cylindrical, and one end thereof is connected to the inside of the main body 2. The other end of the vacuum pipe 81 is connected to a vacuum joint 93 of the rotary joint 9. The hot water inlet pipe 82 is cylindrical, and as described above, one end is connected to the first pipe 71. The other end of the hot water inlet pipe 82 is connected to the hot water inlet joint 91 of the rotary joint 9. The hot water outlet pipe 83 is cylindrical, and as described above, one end is connected to the second pipe 72. The other end of the hot water outlet pipe 83 is connected to the hot water outlet joint 92 of the rotary joint 9.

[0025] [Rotary Joint 9] The rotary joint 9 is configured as a so-called rotary joint that can supply fluid from a fixed pipe to a rotating body. In this embodiment, the rotary joint 9 includes a hot water inlet joint 91, a hot water outlet joint 92, and a vacuum joint 93. That is, in this embodiment, the rotary joint 9 is configured as a three-port rotary joint.

[0026] The hot water inlet joint 91 is connected to a hot water supply pipe 94 that supplies hot water from outside the drying apparatus 1. The hot water outlet joint 92 is connected to a hot water discharge pipe 95 that discharges hot water to the outside of the drying apparatus 1. As a result, hot water supplied via the hot water supply pipe 94 is supplied to the flow path 51 between the main body 2 and the outer jacket 5 via the hot water inlet pipe 82 and the first pipe 71. The hot water that has circulated through the flow path 51 is transmitted to the hot water discharge pipe 95 via the second pipe 72 and the hot water outlet pipe 83. In this way, in this embodiment, hot water can be supplied from outside the drying apparatus 1 and circulated through the flow path 51, so that the object to be dried contained inside the main body 2 can be heated and dried.

[0027] Furthermore, the vacuum joint 93 is connected to a vacuum device outside the drying device 1 via a vacuum piping 96. This allows the vacuum device to be connected to the inside of the main body 2 via the vacuum joint 93 and the vacuum piping 81. Therefore, before the objects to be dried are heated and dried, the air pressure can be reduced by evacuating the inside of the main body 2, thereby increasing the drying efficiency of the objects to be dried.

[0028] As described above, the drying device 1 of this embodiment can provide the following effects. (1) In this embodiment, the stand 3 that rotatably supports the main body 2 is configured to support the main body 2 in a cantilever manner, so that the bearing 33 only needs to be provided on one side of the main body 2. Therefore, the space required to place the drying device 1 can be made smaller than when bearings are provided on both sides of the main body.

[0029] (2) In this embodiment, the main body 2 has the window 23, and therefore, the object to be dried housed in the main body 2 can be checked through the window 23. In this case, the window 23 is provided on the surface of the main body 2 opposite to the surface supported by the stand 3, and therefore, when an operator checks the object to be dried through the window 23, interference with the stand 3 can be prevented.

[0030] (3) In this embodiment, the inner surface of the main body 2 is glass-lined. Therefore, even if the object to be dried is corrosive, corrosion of the main body 2 by the object to be dried can be prevented.

[0031] (4) In this embodiment, the outer jacket 5 is provided on the outer periphery of the main body 2, so that the object to be dried can be heated by circulating hot water as a heat medium through the flow path 51 between the main body 2 and the outer jacket 5.

[0032] [Variations] The present invention is not limited to the configurations of the above-described embodiments, and modifications within the scope of achieving the object of the present invention are included in the present invention.

[0033] In the above-described embodiment, the inner surfaces of the main body 2, first lid 21, and second lid 22 are glass-lined, but this is not limiting. For example, the inner surfaces of the main body, first lid, and second lid may be glass-lined with anti-static glass. This configuration can prevent the powder from adhering to the inside of the main body or causing problems due to static electricity, even if the particles of the powder to be dried become charged due to friction. Furthermore, the present invention also includes a case where the inner surfaces of the main body, first lid, and second lid are not glass-lined.

[0034] In the above-described embodiment, hot water is configured to flow through the flow path 51 between the main body 2 and the outer jacket 5, but this is not limiting. For example, a heat transfer medium such as steam may be configured to flow through the flow path between the main body and the outer jacket. Also, a heat transfer medium does not necessarily have to be configured to flow between the main body and the outer jacket, and the main body may be directly heated.

[0035] In the embodiment described above, the opening at one end of the cylindrical main body 2 is covered by the first lid 21, and the opening at the other end is covered by the second lid 22, but this is not limiting. For example, the main body may be formed in a cylindrical shape with a bottom, and one openable and closable lid may be provided at the opening of the main body. [Explanation of symbols]
