Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drum can heater that melts a substance that is contained in a drum can and is solid at room temperature by heating the drum can as it is.

[0002]

[Prior art]

 If a drum can contains a solid substance at room temperature, it must be taken out of the drum can in a molten state by heating and melting this substance.

Therefore, conventionally, as shown in FIG. 5, a pedestal d for receiving a pallet c on which a drum can b is placed is provided at an inner lower position of the heating chamber a, and steam e is provided at a side portion thereof. A heat transfer tube f having a heat source is provided with a partition wall g, and the drum can b is heated by blowing down the hot air heated by the heat transfer tube f to the upper part. A fan having the above structure is provided so that the heating air is circulated as shown by an arrow.

[0004]

[Problems to be solved by the device]

 However, in the above-described conventional method, the air heated by the heat transfer tube f is blown down from the upper side to the lower side by the fan h provided at the upper portion, so that the drum can b is mainly heated from the upper portion. As a result, the material in the drum can b will also be melted from the upper part, but the heat from above will be transferred to the solids via the liquid in the upper part of the drum can b, resulting in poor efficiency. In addition, since the solid has a larger specific gravity than the liquid, the solid does not melt at the bottom of the drum can b and remains in the shape of a mountain forever, so that it takes a long time to completely melt.

An object of the present invention is to provide a drum can heater capable of efficiently melting a solid substance contained in a drum can in a short time.

[0006]

[Means for Solving the Problems]

 The present invention was made in order to solve the above technical problem, and provided a pedestal for supporting a pallet on which drums were placed on the lower part of the heating chamber, and the air for the pallet and the pedestal on the upper side. A heat transfer tube was provided inside the heating chamber, and the hot air heated by the heat transfer tube was blown upward along the drum in the lower part of the gantry. The present invention relates to a drum can heater having a fan.

[0007]

[Action]

 Therefore, in the present invention, the fan provided in the lower portion blows out the hot air heated by the heat transfer tube upward, and the gantry and the pallet have a shape in which the hot air flowing upward is circulated. The drums on the pallet are effectively heated from below.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention, in which a pedestal for receiving a pallet 3 having a drum 2 mounted on an upper portion of a heating chamber 1 formed of a heat insulating material at a lower position inside the heating chamber 1. 4 is provided on the front surface of the heating chamber 1, and an opening 5 for loading and unloading the drum 2 into the heating chamber 1 together with the pallet 3 is provided on the front surface of the heating chamber 1. An automatic door 7 is provided which is opened and closed by.

Further, a heat transfer tube 10 for guiding the heating steam 8 from the upper portion and the drain 9 from the lower portion is provided at a rear position inside the heating chamber 1 through a partition wall 11, and the pedestal 4 is provided. A fan 13 is provided at the lower part of the drum to heat the drum can 2 by blowing air (hot air) 12 heated by the heat transfer tube 10 upward to circulate the air as indicated by an arrow. Reference numeral 14 represents a fan drive motor.

The pedestal 4 has a support girder structure that allows the hot air 12 from the fan 13 to pass through in order to direct the hot air 12 toward the drum can 2. The pallet 3 also has a structure, for example. As shown in FIGS. 3 and 4, the structure is framed so as to form an opening 15 for passing the hot air 12 upward and a side opening 15 'for letting the hot air 12 escape to the side. In addition, Fig. 3 shows the case where the pallet 3 is made of a wooden frame, but the pallet 3 can be made of metal as long as it can withstand the operating temperature and has slip prevention measures so that it does not slip during transportation. It is also possible to use a material having a porous structure, a mesh structure or the like using a material such as plastic.

In the above structure, the pallet 3 in which a required number of drums 2 each containing a solid substance at room temperature is placed is supported on the pedestal 4 of the heating chamber 1, and the automatic door 7 is used. With the opening 5 closed, the fan 13 is driven by the fan drive motor 14 while supplying the heating steam 8 to the heat transfer tube 10. As a result, the hot air 12 heated by the heat transfer tube 10 is blown upward by the fan 13, and the hot air 12 is directed to the bottom of the drum can 2 through the opening 15 so that the drum can 2 is effective from below. And is further heated in the circumferential direction by the flow of the hot air 12 which flows out from the side opening 15 'and goes upward.

According to the above, the solid in the drum can 2 is melted mainly from below, and the melted substance forms a circulating flow upward in the drum can 2, so that the solid is melted. It is effectively promoted, and thus the melting of the solid can be completed in a short time.

It should be noted that the present invention is not limited to the above-described embodiments, and various changes can be made without departing from the gist of the present invention.

[0015]

[Effect of device]

 As described above, according to the drum can heater of the present invention, the fan provided in the lower portion blows out the hot air heated by the heat transfer tube upward, and causes the hot air flowing upward through the mount and the pallet to flow. As a structure, the drum can on the pallet can be heated from below, so that a circulating flow can be generated in the molten substance in the drum can, and thus the solid in the drum can is efficiently melted within a short time. It is possible to exert an excellent effect.
