JP 2002-209765 A

  The means for covering the periphery of the transport container with a heat insulating material or the like has a problem that the whole including the container becomes very heavy due to the heat insulating material or the like, and is difficult to apply to a large container such as a container. On the other hand, the means for heating after conveyance has a problem that the heating efficiency is low because the substance is heated through the outer wall of the container.

  On the other hand, if a means for heating and stirring from the inside of the container is used for the container for transporting the substance, the substance is sufficiently heated before transporting, and it is not necessary to cover the container with a heat insulating material during transport. The material that has gelled due to a drop in temperature after transportation may be heated and stirred again with a temperature controller and a stirrer attached inside the container. In this case, the problem of low heating efficiency is avoided because the material is directly heated from the inside. it can. Further, this means can be applied to a large container.

  However, if the temperature control device and the stirrer are mounted inside all the transport containers, the cost increases. In addition, it is inefficient if a temperature control device and a stirrer that are not necessary are left in the state where the inside of the container is empty after the stored matter is discharged at the transfer destination.

  Therefore, it is conceivable that the temperature control device and the stirrer are detachable from the container, and the device or the like is provided only at the transport source and transport destination. However, in this configuration, there is a problem that the apparatus and the like have to be detached and attached at the time of transport, and the attachment / detachment work becomes complicated. Further, when the temperature control device and the stirrer are respectively inserted into the container, if the temperature control device and the shaft body of the stirrer are arranged apart from each other, it takes time until heat is sufficiently transferred to the storage in the vicinity of the shaft body. Take it. Therefore, when the gelled substance inside the container is a substance having a high viscosity, the stored matter becomes entangled with the shaft body of the stirrer due to the temperature change, thereby preventing the rotation. As a result, resistance to the rotation of the stirrer is generated, resulting in a problem that the stirring efficiency is lowered.

  In order to avoid the above-mentioned problem, even if the shaft body is inserted into the insertion side end of the temperature control device inserted into the container and the device and the stirrer are integrated, the substance remains in the temperature control device. Problems such as clogging occur due to intrusion into the inside of the temperature control device through the gap at the end entrance.

  The present invention has been made paying attention to such problems, and an object of the present invention is to provide a transport container that can be easily attached to and detached from a container for storing a substance and has excellent heat retention workability.

A first characteristic configuration of the present invention includes a container for storing a storage, a temperature control device that is detachably inserted into the container and controls the temperature of the storage, and a shaft body for stirring the storage. In a transport container having a shaft member provided with a stirring blade and a stirrer provided with a drive source for rotating the shaft member , a groove is formed on the outer peripheral surface of the temperature control device in parallel to the shaft center, and the shaft member The shaft body passes through the groove portion without contacting the surface thereof .

According to this structure, a temperature control apparatus and a stirrer are comprised compactly, and attachment or detachment to the containers, such as the said apparatus, becomes easy. Further, by forming the temperature control device so as to cover the shaft body of the stirrer, the storage in the vicinity of the shaft body is preferentially heated. Therefore, even if the stored matter is entangled with the shaft body of the stirrer due to a temperature change and has a property of preventing rotation, the stirrer can be rotated by returning the stored material entangled near the shaft body to the original state by such heating. Can be reduced, and efficient stirring can be achieved. Furthermore, the cleaning operation is facilitated by forming the groove on the outer peripheral surface. In particular, when the deposit attached to the temperature control device is a substance having a high viscosity, the removal operation is facilitated.

The second characteristic configuration of the present invention is that the temperature control device includes a heat source and a heat medium that fills the periphery of the heat source.

  As in this configuration, by providing a heat medium around the heat source, the stored material does not directly touch the heat source, and the stored material can be prevented from being burnt. Further, by disposing a heat source in a part of the inside of the apparatus and transferring heat to the entire apparatus by the heat medium, it is not necessary to arrange the heat source in the entire apparatus, and efficient heating is possible.

A third characteristic configuration of the present invention is that the temperature control device and the stirrer are configured as an integral unit, and gripping means for mounting and detaching the unit to and from the container is provided in the unit. is there.

  The temperature control device and the agitator are formed to be attachable to and detachable from the container. As in this configuration, the temperature control device and the stirrer are configured as an integral unit, and gripping means for attaching and detaching the unit to and from the container is provided in the unit, so that the unit during cleaning or transportation is provided. Mounting and detaching work on the container is facilitated.

According to a fourth characteristic configuration of the present invention, the bottom of the container is pointed downward, a discharge port for discharging the stored matter is formed at the tip, and the stirring blade is close to the discharge port. It is in the point set.

  By draining the bottom of the container downward and providing a discharge port at the tip, it is easy to discharge the stored material inside the container. In addition, by providing a stirring blade near the discharge port, when the stored matter is a mixture, some constituent substances precipitated in the lower layer inside the container in which the stirring blade is located are effectively stirred and stored immediately before discharge. It is possible to achieve homogenization of the stored matter that is sufficiently agitated and discharged.

  An embodiment of a transport container according to the present invention will be described based on the drawings. FIG. 1 shows a cross-sectional view of a transport container 1 according to the present invention. The container 2 has a quadrangular prism shape, and a circular insertion port 2a is provided at the center of the upper surface thereof. The bottom is pointed downward, and the end is provided with a discharge port 2b, to which a discharge valve 6 is connected. Inside the container 2, there is a storage 3 such as water-resistant glue that has the property of gelling due to a temperature drop and returning to its original state when heated.

  As shown in FIG. 1, FIG. 2, FIG. 4 and FIG. 5, the temperature control device 4 has a cylindrical shape, and the diameter of the main body is slightly smaller than the inner diameter of the insertion port 2a. It can be inserted inside. On the other hand, the diameter of the upper surface 4a of the temperature control device 4 is formed larger than the outer diameter of the insertion port 2a, whereby the temperature control device 4 is locked. On the outer peripheral surface of the temperature control device 4, a U-shaped groove 4 c is formed in parallel to the axis. A drive source 51 for rotating the shaft member 54 is provided on the groove opening on the upper surface 4a side of the temperature control device 4 of the groove portion 4c. An operation unit 41 for controlling the temperature of the stored material is also provided on the upper surface 4a. A support leg 44 is provided on the lower surface 4b side of the temperature control device 4 so as to stand upright on a plane when the device is detached. As shown in FIG. 5, the support foot 44 has the same diameter as the bottom surface 4 b that connects three equal-length support columns extending downward from the outer periphery of the bottom surface 4 b of the temperature control device 4 and their ends. It is composed of a ring-shaped bottom.

  As shown in FIGS. 3 and 4, a heat source 42 is suspended from the position of the upper surface 4 a of the temperature control device 4 below the inside of the temperature control device 4. A heat medium 43 is filled around the heat source 42 throughout the temperature control device 4. For example, water or glycerin is used as the heat medium 43. In particular, it is preferable to use glycerin which is not flammable and does not evaporate immediately. Inside the heat medium 43 is a temperature sensor (not shown). Thus, the temperature of the storage medium 3 is indirectly controlled by detecting the temperature of the heating medium 43 and controlling the temperature of the heating medium 43. A material having high thermal conductivity is used for the outer layer of the main body of the temperature control device 4 covering the heat medium 43. Then, heat exchange is performed between the main body surface of the temperature control device 4 and the storage 3.

  As shown in FIGS. 1 and 5, the agitator 5 includes the drive source 51 and the shaft member 54. The agitator 5 is integrally attached to the temperature control device 4 and constitutes one unit. The shaft member 54 includes a shaft body 52 and a stirring blade 53. One end of the shaft body 52 is connected to the drive source 51, and its main body extends along the groove portion 4c without contacting the groove portion 4c, and a stirring blade 53 is provided at the other end. The stirring blade 53 is located in the vicinity of the lower surface 4 b of the temperature control device 4. Note that the rotational speed of the drive source 51 and the stirring blade 53 are designed to be changeable depending on the viscosity of the storage 3 and the like.

  As in this configuration, a U-shaped groove portion 4c is formed on the outer peripheral surface of the temperature control device 4 in parallel with the axis, and the shaft body 52 is disposed along the groove portion. The apparatus 4 and the stirrer 5 are configured in a compact manner, and can be easily attached to and detached from the container 2. Further, since the groove 4c is formed so as to cover the shaft body 52, when the reservoir 3 that has been gelated due to a temperature drop is heated and stirred by the temperature control device 4 and the stirrer 5, the shaft is caused by the groove. The periphery of the body 52 is effectively heated. Furthermore, since the stirring blade 53 is also in the vicinity of the lower surface 4b of the temperature control device 4, similarly, the periphery of the stirring blade 53 is effectively heated. Therefore, even when the viscosity of the reservoir 3 that has gelled due to a temperature drop is high, the entanglement with respect to the shaft member 54 is avoided by returning the reservoir 3 in the vicinity of the shaft member 54 to the original state. The resistance to the rotation of the stirrer 5 is reduced, and efficient stirring is possible even at the beginning of heating.

  Further, in the temperature control device 4, since the groove 4c is outside, the cleaning operation is easy. For example, when the reservoir 3 attached to the temperature control device 4 is glue or the like, it can be easily removed by making a cut along the axial direction after drying, and the removal operation becomes easy. . If an anti-adhesive agent is applied in advance on the surface of the temperature control device 4, it is more effective.

  When the heating means of the temperature control device has a structure that directly contacts the stored matter, there arises a problem that the stored matter is burnt on the surface of the heating means depending on the property of the stored matter. As in this configuration, the surroundings of the heat source 42 are filled with a heat medium 43 such as water or glycerin, and indirectly heated, so that it can be applied to the case of heating a reservoir that causes such burning. is there. Further, according to this configuration, heat can be efficiently conducted from the heat source 42 arranged in a part of the inside of the apparatus to the entire apparatus by the heat medium 43.

  The temperature control device 4 and the stirrer 5 are detachably attached to the container 2. Therefore, for example, if the temperature control device 4 and the stirrer 5 are provided at the transport source and the transport destination, the temperature control device 4 and the stirrer 5 are detached at the transport source, and these are mounted again at the transport destination. Thus, the weight of the transport container during transport can be reduced. As shown in FIGS. 1 and 6, if the unit is provided with the gripping means 7, it is easier to attach and detach the unit to and from the container 2. Here, for example, the example in which the gripping means 7 is provided at the position of the upper surface 4a of the temperature control device 4 is shown. The gripping means 7 is provided with a pair of square cylinders 71. The rectangular cylinder 71 is formed so that a fork of a forklift can be inserted. By inserting the fork of the forklift into the rectangular cylinder 71, the unit can be moved using the forklift, and the unit can be easily attached to and detached from the container 2.

  Further, when the stored material is a mixture, there is a problem that some of the constituent materials are precipitated in the lower layer inside the container. As in this configuration, by providing the stirring blade 53 in the vicinity of the discharge port 2b, a part of the constituent substances precipitated in the inner lower layer of the container 2 is effectively stirred, and the storage immediately before the discharge It is possible to provide a well-reserved product in which the object 3 is agitated and homogenized. In addition, as in the present configuration, the reservoir 3 inside the container 2 can be easily discharged by making the bottom of the container 2 pointed downward. And by providing the said discharge valve 6 in the said discharge port 2b, it is also possible to use the conveyed container as it is as a supply tank in the work line which uses the storage inside a container, for example.

[Another embodiment 2]
FIG. 7 shows another embodiment of the transport container according to the present invention. The temperature control device 4 in the present embodiment is divided into three cylindrical blocks, some of which are connected to each other, and each block has a shaft passage portion 4c ′ through which the shaft body 52 is inserted along the axis. Is formed. Then, heat exchange is performed between the block surface and the stored material 3. In addition, stirring blades 53 are provided in the vicinity of the inter-block portions and the tip portions of the shaft body 52 inserted through the shaft passage portion 4c ′.

  According to the present embodiment, the shaft body 52 is inserted into the shaft passage portion 4c ′ provided in the temperature control device 4, so that the temperature control device 4 and the stirrer 5 are configured compactly, and the temperature control device 4 and the stirrer 5 are configured. Is easily attached to and detached from the container 2 and the periphery of the shaft body 52 is effectively heated. Furthermore, since the stirring blades 53 are located in the vicinity of each block of the temperature control device, similarly, the periphery of the stirring blades 53 is also effectively heated. Accordingly, even when the viscosity of the storage 3 gelated due to the temperature drop is high, the storage 3 in the vicinity of the shaft member 54 is returned to the original state, thereby preventing the shaft member 54 from being entangled and against the rotation of the stirrer. Resistance can be reduced, and as a result, efficient stirring is possible even at the beginning of heating. Furthermore, the stirring force can be further improved by providing a plurality of stirring blades 53.
