Description

Technical Field

[0001] The present application relates to the field of foam box production, and in particular to a hot air circulation structure for a drying room. Background Art

[0002] The foam box needs to go through a series of process steps in the production process, including foaming, molding, drying and curing. As an important equipment, the drying room plays a key role in it.

[0003] Specifically, the drying room's primary function is to promote the drying and curing of foam box materials by providing a specific temperature and humidity environment. During the drying phase, the drying room helps remove excess moisture from the foam box, preventing quality issues caused by excessive moisture content during use. During the curing phase, the drying room provides sufficient heat to cross-link the chemical substances in the foam box material, thereby enhancing its structural stability and durability.

[0004] In existing drying rooms, a heat pipe is installed at the bottom of the drying room, and the foam box is placed on top of the heat pipe. During operation, a high-temperature heat transfer medium is introduced into the heat pipe. The air at the bottom of the drying room is heated by the heat transfer medium, forming hot gas that flows upward, heating the foam box as it rises. After rising to the top of the drying room, this hot gas still contains a lot of energy. If it is directly discharged, it will result in energy waste. Therefore, a hot gas circulation structure is needed to effectively utilize the energy contained in this hot gas and reduce energy waste. Utility Model Content

[0014] By adopting the above technical solution, the electric telescopic rod is used to control the relative position of the connecting rod and the collecting tube, thereby controlling the angle of the cover plate, thereby improving the convenience of adjusting the cover plate angle.

[0017] Optionally, the circulation pipe sleeve is provided with a heat insulating sleeve.

[0018] By adopting the above technical solution, the heat loss during the movement of hot air in the circulation pipe is reduced.

[0019] Optionally, a plurality of airbags are provided on the inner wall of the heat-insulating sleeve, and the airbags are arranged around the circumference of the circulation pipe, and the plurality of airbags are arranged along the length direction of the circulation pipe.

DETAILED DESCRIPTION

[0034] The present application will be further described in detail below with reference to FIG. XX.

[0035] The embodiment of the present application discloses a hot air circulation structure for a drying room.

[0036] Example 1

[0037] Reference Figure 1 and Figure 2 A hot air circulation structure for a drying room includes a collection pipe 1, a circulation pipe 2, and a heating device 3. Multiple collection pipes 1 are provided, each mounted on the ceiling of the drying room. The circulation pipe 2 is mounted on the outer wall of the drying room. Each of the collection pipes 1 is connected to one end of the circulation pipe 2, and the other end of the circulation pipe 2 is connected to a heat dissipation pipe.

[0038] The heating device 3 is mounted on the circumference of the circulation pipe 2. Multiple collection holes 11 are formed through the wall of the collection pipe 1, spaced apart along its length. Multiple cover plates 12 are rotatably attached to the circumference of the collection pipe 1, used to open and close the collection holes 11. Each cover plate 12 corresponds to a corresponding collection hole 11.

[0039] Before use, adjust the cover plate 12 to the appropriate position based on the volume, arrangement density, and desired temperature of the foam boxes placed in the drying room. Hot air rises through the drying room, enters the collection pipe 1 through the vents, then flows along the collection pipe 1 into the circulation pipe 2. It is then heated to the desired temperature by the heating device 3 and enters the bottom of the drying room through the heat dissipation pipe.

[0040] It is worth noting that the circulation pipe 2 includes a conveying section 21 and a heating section 22. The end of the collecting pipe 1 is connected to one end of the conveying section 21, the heating section 22 is connected to the end of the conveying section 21 away from the collecting pipe 1, and the heating device 3 is installed in the heating section 22.

[0041] A one-way valve 23 is provided on the inner wall of the circulation pipe 2. The one-way valve 23 is connected to the connection position between the conveying section 21 and the heating section 22. The one-way valve 23 is used to prevent the gas from entering the conveying section 21 from the heating section 22, so as to reduce the risk of the hot gas in the circulation pipe 2 flowing back to the collecting pipe 1, thereby ensuring the operating stability of the circulation structure.

[0042] In this embodiment, the cover plate 12 is integrally formed with the collection tube 1, i.e., a movable piece is formed at the cutout portion of the tube wall of the collection tube 1, and the piece can then be bent relative to the collection tube 1. In other embodiments, the cover plate 12 can also be connected to the collection tube 1 by a hinge with greater friction.

[0043] Reference Figure 3 Furthermore, the collecting tube 1 is connected to a connecting rod 13, which extends along the length direction of the collecting tube 1. The multiple cover plates 12 connected to the same collecting tube 1 are all connected to the connecting rod 13, so that the angles of the multiple cover plates 12 connected to the same collecting tube 1 can be adjusted by applying force to one connecting rod 13, thereby improving the adjustment efficiency.

[0044] In this embodiment, the surface of the cover plate 12 facing away from the collecting hole 11 is used to connect to the connecting rod 13, and the connecting rod 13 is welded to the cover plate 12. In other embodiments, the connecting rod 13 and the cover plate 12 can also be detachably connected by a snap connection. When the angle of the cover plate 12 does not need to be adjusted for a long time, the connecting rod 13 can be removed from the cover plate 12 to reduce the load on the cover plate 12.

[0045] Reference Figure 2 and Figure 4 Furthermore, a pressure sensor 15 and a control terminal 16 are mounted on the surface of the collection tube 1 facing the heat pipe. The pressure sensor 15 is electrically connected to the control terminal 16. The pressure sensor 15 is used to detect the air pressure signal on the lower surface of the collection tube 1 and transmit the air pressure signal to the control terminal 16.

[0046] An electric telescopic rod 14 is hinged to the drying room's ceiling. The end of the rod 14, facing away from the ceiling, is hinged to a connecting rod 13. This rod 14 is electrically connected to a control terminal 16, which controls its extension and retraction based on received air pressure signals. This design pre-sets parameters in the control terminal 16. When the hot air pressure drops below or rises above a certain threshold, the control terminal 16 activates the electric telescopic rod 14, driving the connecting rod 13 to rotate, thereby achieving automated control of the angle of the cover plate 12.

[0047] The implementation principle of Example 1 is as follows: before the drying room is used, the angle of the cover plate 12 is adjusted according to the specific conditions of the foam box to be processed; when the drying room is working, under the heating of the heat dissipation pipe, the air temperature at the bottom of the drying room increases and moves upward. When it moves to the top of the drying room, it enters the collection pipe 1 from the collection hole 11, and then enters the circulation pipe 2 from the collection pipe 1. After being heated by the heating device 3, it enters the heat dissipation pipe for recycling, so as to realize the reuse of heat in the drying room and reduce energy waste.

[0048] Example 2

[0049] Reference Figure 5 and Figure 6 ,,The difference between this embodiment and embodiment 1 is that the circulation pipe 2 is provided with a heat insulating sleeve 4 to reduce heat loss during the movement of hot air in the circulation pipe 2.

[0050] The circulation sleeve has an opening and closing slit 41 along its length, with both ends of the opening and closing slit 41 extending through the two end faces of the insulation sleeve 4. The insulation sleeve 4 is provided with a zipper 42 extending along the length of the opening and closing slit 41. The zipper 42 is used to open and close the opening and closing slit 41 to achieve a detachable connection between the insulation sleeve 4 and the circulation pipe 2, and to improve the convenience of disassembly and assembly of the insulation sleeve 4.

[0051] The inner wall of the insulating sleeve 4 is provided with a plurality of air pockets 43, which are arranged around the circumference of the circulation pipe 2 and arranged along the length of the circulation pipe 2. When installing the insulating sleeve 4, the insulating sleeve 4 is first placed around the circulation pipe 2, then the zipper 42 is closed and the air pockets 43 are inflated. The still air in the air pockets 43 and the insulating sleeve 4 form a multi-layer insulation, further reducing the risk of heat loss from the hot air in the circulation pipe 2.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
