[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a panel member for forming a furnace wall of a drying furnace.

[0002]

[Prior art]

 It is important to maintain the baking temperature and baking time uniformly and stably in order to heat and dry the product coated with the paint (hereinafter referred to as a work) in a drying oven with high quality. For example, in the case of an automobile body coated with a cationic paint, the baking temperature is 180 ° C. and the baking time is 20 minutes. Therefore, the conventional drying furnace requires a long-time treatment at such a high temperature, and therefore, as shown in Japanese Utility Model Publication No. 60-7814, the work in the longitudinal direction of a long tunnel type furnace body (for example, 80 m) is performed. It is generally configured to circulate hot air having a constant temperature in the furnace while conveying the air.

As described above, since the furnace main body becomes long, it is common to construct a furnace main body by connecting a plurality of furnace wall forming panel members through a connecting member so as to be capable of thermal expansion absorption at an assembly site. is there.

Here, the furnace wall forming panel member is, as shown in FIG. 5, a metal inner panel 3 having a flat rectangular shape, and a metal outer panel in which the entire circumference of an edge portion is joined to the metal inner panel 3. 5 and the heat insulating material 4 and the like filled between the panels 3 and 5 (in FIG. 5, the upper portion of the panel member is shown in a sectional view). A reinforcing material (not shown) is often incorporated between the panels 3 and 5.

[0005]

[Problems to be solved by the device]

 By the way, in the drying oven constructed by using the oven wall forming panel member described above, the heat in the oven easily escapes from the inner panel 3 through the outer panel 5, and it is difficult to maintain the oven temperature constant. It has drawbacks. In addition, since the joint portions of both panels 3 and 5 are long, there is a drawback that joining work (welding work) and then assembly work are troublesome.

In view of the above circumstances, an object of the present invention is to provide a furnace wall forming panel member for a drying furnace, which does not easily transfer heat and can shorten the assembly time.

[0007]

[Means for Solving the Problems]

 An oven wall forming panel member of a drying oven according to the present invention includes an inner panel portion that can form an oven wall inner surface, an outer panel portion that can form an oven wall outer surface, and both panel portions. It is characterized in that it is configured to include a joining member that joins so that a void portion is formed in.

[0008]

[Action]

 In the present invention having the above structure, the inner panel portion and the outer panel portion are joined by the joining member so that a gap is formed therebetween. Here, by forming the joining member small in a range that does not hinder the assembly, it is possible to reduce the contact area of both panel portions joined together through the joining member and to secure a vast void. It Here, since the void portion serves as a heat insulating layer, the heat transfer path becomes narrow and it becomes difficult to transfer heat.

Further, since the joint portion of both panel portions is small, it is possible to shorten the assembly time without taking time and effort for the joint work.

Therefore, it is difficult to transfer heat and the assembly time can be shortened.

【Example】

 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a cross-sectional view showing a part of a drying oven to which the embodiment is applied, and FIG. 3 is a part of a drying oven to which the embodiment is applied. FIG. 4 is a side sectional view and FIG. 4 is a sectional view taken along the line AA in FIG.

An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 4, the oven wall forming panel member 10 of the drying oven according to the present embodiment includes an inner panel portion 11, an outer panel portion 21, and a joining member (31).

Here, the inner panel portion 11 is for forming the inner surface of the oven wall of the drying furnace, and has a metal main body 12 formed in a thin box shape with one side surface portion 12a opened, and the main body 12 The heat insulating material 13 filled is included. Further, a predetermined number of connecting holes 14 are formed through each side end surface of the main body 12. Further, a reinforcing material 19 for increasing the structural strength is attached to the main body 12.

The outer panel portion 21 is for forming the outer surface of the oven wall of the drying furnace, and has a metal main body 22 formed into a thin box shape with one side surface portion 22 a opened, and the main body 22 is filled with the metal main body 22. The heat insulating material 23 is included. The main body 22 is formed to be smaller in vertical and horizontal dimensions than the main body 12 of the inner panel portion 11, and a flange portion 25 is formed on the entire circumference of the end portion on the opening side. The body 22 is filled with a heat insulating material 23. A reinforcing member 39 is attached to the main body 22.

The joining member (31) is a member that connects the inner panel portion 11 and the outer panel portion 21 so that a gap G is formed between the two (11, 21). In this embodiment, as shown in FIG. 1, the joining members are a predetermined number (five in this embodiment) of joining plates 31 that are hung in parallel on the long side end of the main body 12 of the inner panel portion 11. Is formed. Each joint plate 31 is formed to have a minimum width dimension within a range that does not hinder the joining (welding) of both panel portions 11 and 21. In FIGS. 2 and 3, reference numeral 9 denotes a furnace mount, and the furnace wall forming panel member 10 is assembled on the furnace mount 9.

Next, the operation will be described. The inner panel portion 11 and the outer panel portion 21 are joined by a plurality of joining plates 31 so that a gap G is formed between the two (11, 21). Here, since the width dimension of each bonding plate 31 is minimized, the contact area of both panel parts 11 and 21 bonded (welded) via the bonding plate 31 is significantly reduced as compared with the conventional case. At the same time, a vast space G is secured. Here, since the void G forms a heat insulating layer, the heat transfer path from the inner panel portion 11 to the outer panel portion 21 becomes narrow. Therefore, it becomes difficult for heat to be transferred.

Further, since the joint portion between both panel portions 11 and 21 is small, it is possible to shorten the assembling time without taking time and effort for the joining work (welding work).

Further, as described above, since the furnace wall forming panel member 10 is unitized, it is possible to assemble much more simply and quickly. That is, after each panel member 10 is temporarily fixed by using bolts or the like, the side end surfaces of the inner panel portion 11 of each panel member 10 can be assembled by simply welding, and the assembling time can be shortened. The space between the outer panel portions 21 and 21 of the adjacent panel members 10 and 10 is covered with a decorative plate 27 and then filled with a heat insulating material.

Therefore, according to this embodiment, the inner panel portion 11 capable of forming the inner surface of the oven wall of the drying oven, the outer panel portion 21 capable of forming the outer surface of the oven wall, and both panel portions 11 and 21 are provided. Since it is configured to include the joining member (each connecting plate 31) that joins so that the gap G is formed between (11, 21), it is difficult to transfer heat and the assembling time can be shortened.

Further, since the joining member is formed by the plurality of joining plates 31 arranged in parallel, it is possible to improve the workability and reduce the contact area to make it more difficult to transfer heat. it can.

In the above embodiment, the joining member is formed of the plurality of joining plates 31, but it is possible to join the two panel portions 11 and 21 so that the gap G is formed between them. You may form so.
