[0030] The utility model provides an oven, which can be a tunnel oven, etc. Figure 1 and Figure 2 A preferred embodiment of the oven provided by the utility model is shown.
[0031] See also Figure 1 and Figure 2 In this embodiment, the oven 1000 includes a preheating module 100, a cooling module 200 and a clean air recovery duct 300. The preheating module 100 is provided with a recovery air inlet 110; the cooling module 200 is provided with a cooling module exhaust port 210, so that the clean air in the cooling module 200 can be discharged from the cooling module exhaust port 210; the two ends of the clean air recovery duct 300 are respectively connected to the recovery air inlet 110 and the cooling module exhaust port 210, so that the clean air discharged from the cooling module 200 passes through the clean air recovery duct 300 and enters the preheating module 100 from the recovery air inlet 110.
[0032] Specifically, the oven 1000 includes a preheating module 100, a heating module 400 and a cooling module 200 which are connected in sequence, and the heating module 400 is located between the preheating module 100 and the cooling module 200. A preheating chamber (not shown in the figure) is formed in the preheating module 100, and the recovery air inlet 110 is connected to the preheating chamber. A cooling chamber (not shown in the figure) is formed in the cooling module 200, and an exhaust duct (not shown in the figure) is arranged on the cooling module 200. The exhaust duct of the cooling module 200 is connected to the cooling chamber, so that the air in the cooling module 200 can be discharged to the outside through the exhaust duct, and the exhaust duct of the cooling module 200 is provided with a cooling module exhaust port 210, so that the air in the cooling module 200 can be discharged to the outside from the cooling module exhaust port 210 after passing through the exhaust duct.
[0033] The two ends of the clean air recovery duct 300 are respectively connected to the cooling module exhaust port 210 of the cooling module 200 and the recovery air inlet 110 of the preheating module 100. The air discharged from the cooling module exhaust port 210 in the cooling module 200 can enter the preheating module 100 from the recovery air inlet 110 after passing through the clean air recovery duct 300. Since the air discharged from the cooling module 200 is the air after cooling the bottle body, it is the air that meets the cleanliness requirements, and direct discharge causes waste to a certain extent. The oven 1000 recycles all the clean air discharged from the cooling module 200 and supplies it to the recovery air inlet 110 of the preheating module 100. In this way, the air volume taken from the clean room by the preheating module 100 becomes less, which is conducive to the stability of the pressure difference in the room and the equipment, reduces energy loss, helps to reduce the operating cost of the equipment, and can reduce external exhaust.
[0034] The utility model connects the cooling module exhaust port 210 of the cooling module 200 and the recovery air inlet 110 of the preheating module 100 through the clean air recovery pipe 300, and the clean air exhausted by the cooling module 200 is recovered and reused by the preheating module 100 through the clean air recovery pipe 300, thereby reducing the air volume taken by the preheating module 100 from the clean room, which is beneficial to the stability of the pressure difference in the clean room and the equipment, reduces energy loss, and helps to reduce the operating cost of the equipment.
[0035] Since the exhaust duct of the cooling module 200 is no longer connected to the exhaust system in the clean room, all the clean air exhausted from the cooling module 200 is recycled by the preheating module 100 through the clean air recovery duct 300. Optionally, in this embodiment, an air volume regulating valve (not shown in the figure) is provided on the clean air recovery duct 300. The exhaust volume of the cooling module 200 can be controlled by the air volume regulating valve, thereby ensuring the pressure difference balance inside the equipment.
[0036] Optionally, see Figure 1 and Figure 2 In this embodiment, a clean room air inlet (not shown in the figure) is provided on the preheating module 100 to allow the air in the clean room to enter the preheating module 100 from the clean room air inlet, and the recovery air inlet 110 can be connected to the clean room air inlet.
[0037] Specifically, the preheating module 100 is provided with a first exhaust duct (not shown in the figure), and the clean room air inlet is connected to the first exhaust duct and the preheating chamber. When the first exhaust duct is working, a negative pressure is formed in the preheating chamber, so that the air in the clean room can enter the preheating module 100 from the clean room air inlet. Among them, the first exhaust duct is usually provided with a first regulating valve, and the air volume directly taken from the clean room by the preheating module 100 can be controlled by the first regulating valve.
[0038] Similarly, the cooling module 200 is usually provided with an air supply port (not shown in the figure) and a second exhaust duct (not shown in the figure). The air supply port is connected to the second exhaust duct and the cooling chamber. When the second exhaust duct is working, a negative pressure is formed in the cooling chamber, so that the air in the clean room can enter the cooling module 200 from the air supply port. The second exhaust duct is provided with a second regulating valve, and the air volume directly taken from the clean room by the cooling module 200 can be controlled by the second regulating valve.
[0039] The recycled air inlet 110 and the clean room air inlet can be the same air inlet on the preheating module 100, that is, one air inlet on the preheating module 100 is connected to the first exhaust duct and the clean air recycling duct 300. Of course, the recycled air inlet 110 and the clean room air inlet can also be two air inlets on the preheating module 100 respectively.
[0040] When the recycled air inlet 110 and the clean room air inlet are two air inlets on the preheating module 100, the recycled air inlet 110 and the clean room air inlet can be directly connected to the preheating chamber. For example, the recycled air inlet 110 and the clean room air inlet are directly arranged on the box body of the preheating module 100.
[0041] When the recycling air inlet 110 and the clean room air inlet are two air inlets on the preheating module 100, the recycling air inlet 110 and the clean room air inlet may be the first one directly connected to the preheating chamber, and the second one indirectly connected to the preheating chamber through the first one. For example, the clean room air inlet is directly arranged on the box body of the preheating module 100, and the box body of the preheating module 100 is provided with a connecting structure such as a hood or a connecting pipe, the connecting structure is connected to the clean room air inlet, and the recycling air inlet 110 is arranged on the connecting structure. In this case, the recycling air inlet 110 is a branch of the clean room air inlet, and the clean air discharged from the cooling module 200 passes through the recycling air inlet 110 and the clean room air inlet in turn and then enters the preheating module 100.
[0042] Furthermore, in this embodiment, a filter (not shown in the figure) is installed at the air inlet of the clean room. The filter may be a medium-efficiency filter, etc. The filter can filter the air entering from the air inlet of the clean room.
[0043] Optionally, see Figure 1 and Figure 2In this embodiment, the clean room air inlet is arranged on the top surface of the preheating module 100, and a hood 120 is arranged on the top surface of the preheating module 100. The hood 120 is arranged on the upper side of the clean room air inlet, and the recovery air inlet 110 is arranged on the hood 120. The hood 120 can guide the air, which is conducive to the air entering the preheating module 100 from the clean room air inlet. Among them, the recovery air inlet 110 can be fixed on the hood 120 by welding or other methods.
[0044] For further information, see Figure 1 and Figure 2 In the present embodiment, the recovered air inlet 110 is disposed on the side wall of the hood 120 close to the cooling module 200 .
[0045] Specifically, the recovered air inlet 110 is arranged on the side wall of the wind hood 120 facing the cooling module 200. The recovered air inlet 110 is oriented horizontally and faces the cooling module 200, so that it is convenient to connect one end of the clean air recovery duct 300 with the recovered air inlet 110.
[0046] Optionally, see Figure 1 and Figure 2 In this embodiment, a cooling module exhaust duct 220 is provided on the cooling module 200, the lower end of the cooling module exhaust duct 220 is connected to the bottom of the cooling module 200, the upper end of the cooling module exhaust duct 220 protrudes upward from the cooling module 200, and the cooling module exhaust port 210 is provided at the upper end of the cooling module exhaust duct 220.
[0047] Specifically, the exhaust duct of the cooling module 200 includes a cooling module exhaust duct 220 and a fan (not shown in the figure), the fan is arranged at the bottom of the cooling module 200, and the air inlet and the air outlet of the fan are respectively connected to the bottom of the cooling chamber and the lower end of the cooling module exhaust duct 220. The cooling module exhaust duct 220 is arranged to extend in the up-down direction, the upper end of the cooling module exhaust duct 220 protrudes upward from the top surface of the cooling module 200, and the upper end of the cooling module exhaust duct 220 is provided with an upward cooling module exhaust port 210. In this way, the cooling module exhaust duct 220 and the recovery air inlet 110 are both located on the upper side of the box body of the oven 1000, so that the clean air recovery duct 300 is also located on the upper side of the box body of the oven 1000, so that the clean air recovery duct 300 is not easy to interfere with other components installed on the box body.
[0048] Optionally, see Figure 1 and Figure 2In this embodiment, the clean air recovery duct 300 is located on the upper side of the heating module 400. The clean air recovery duct 300 is located on the upper side of the preheating module 100, the heating module 400 and the cooling module 200. The clean air recovery duct 300 starts from the preheating module 100, passes through the heating module 400 and extends to the cooling module 200.
[0049] Optionally, see Figure 1 and Figure 2 In this embodiment, the clean air recovery duct 300 includes an air recovery channel 310 and a recovery channel transfer tube 320. One end of the air recovery channel 310 is connected to the recovery air inlet 110, and the other end of the air recovery channel 310 is connected to one end of the recovery channel transfer tube 320. The other end of the recovery channel transfer tube 320 is connected to the cooling module exhaust port 210.
[0050] Specifically, the air recovery channel 310 is usually a metal corrugated hose, for example, the air recovery channel 310 can be a stainless steel corrugated hose, etc. Taking advantage of the metal corrugated hose's ability to expand and bend, it is convenient to connect the recovered air inlet 110 with the cooling module exhaust port 210 through the clean air recovery duct 300.
[0051] Optionally, see Figure 1 and Figure 2 In the present embodiment, a first flange structure 330 is provided between the recovery channel transfer tube 320 and the cooling module exhaust port 210 , so that the recovery channel transfer tube 320 and the cooling module exhaust port 210 can be docked through the first flange structure 330 .
[0052] Specifically, a first flange structure 330 is provided between the recovery channel adapter tube 320 and the cooling module exhaust port 210, so as to facilitate the connection between the clean air recovery duct 300 and the cooling module exhaust port 210. For example, the cooling module exhaust port 210 has a square flange, and correspondingly, the recovery channel adapter tube 320 has a square flange at one end close to the cooling module exhaust port 210, and a mounting circular hole is provided on the square flange.
[0053] Optionally, see Figure 1 and Figure 2 In this embodiment, a second flange structure 340 is provided between the air recovery channel 310 and the recovery channel transfer tube 320 so that the air recovery channel 310 and the recovery channel transfer tube 320 can be connected through the second flange structure 340 .
[0054] Specifically, a second flange structure 340 is provided between the air recovery channel 310 and the recovery channel adapter tube 320 to facilitate docking of the air recovery channel 310 with the recovery channel adapter tube 320. For example, the end of the recovery channel adapter tube 320 away from the exhaust port 210 of the cooling module has a round flange, and correspondingly, the end of the air recovery channel 310 close to the recovery channel adapter tube 320 has a round flange, and a mounting round hole is provided on the round flange.
[0055] Optionally, see Figure 1 and Figure 2 In the present embodiment, a third flange structure 350 is provided between the recovered air inlet 110 and the air recovery channel 310 , so that the recovered air inlet 110 and the air recovery channel 310 can be docked through the third flange structure 350 .
[0056] Specifically, a third flange structure 350 is provided between the recycled air inlet 110 and the air recycling channel 310, so as to facilitate the connection between the clean air recycling duct 300 and the recycled air inlet 110. For example, the end of the air recycling channel 310 away from the recycling channel transfer tube 320 has a round flange, and correspondingly, the recycled air inlet 110 is a round tube welded with a round flange, and a mounting round hole is provided on the round flange.
[0057] During the normal operation of the oven 1000, the clean air exhausted by the cooling module exhaust duct 220 is recycled by the preheating module 100 through the recovery channel transfer tube 320 and the air recovery channel 310. At the same time, the preheating module 100 draws fresh air from the clean room through the clean room air inlet. Since part of the air volume required by the preheating module 100 is provided by the clean air exhausted by the cooling module 200, the air volume drawn from the clean room will become less, which is more conducive to the stability of the pressure difference in the clean room and the equipment.
[0058] Only one clean air recovery duct 300 needs to be opened on the oven 1000, and other airflow chambers and channels do not need to be considered, and the airflow and pressure difference in the entire device will not be affected.
[0059] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
