[0032] Drying ovens can be divided into industrial drying ovens and household drying ovens according to different usage scenarios. Drying ovens can quickly dry the moisture of the objects to be dried. Currently, multi-layer continuous drying ovens are widely used. The air circulation design of the multi-layer continuous drying oven system is very important, mainly reflected in ensuring the stable operation of the heat source system and the uniformity of material drying.

[0033] There are technical problems in the drying ovens in the related art, such as large fan power, which increases the operating energy consumption and thus affects the overall operating effect of the system.

[0034] Please refer to Figure 1 - Figure 2, this embodiment provides a continuous drying oven structure, which can effectively improve the above-mentioned technical problems, reduce the operating energy consumption and save costs.

[0035] Please refer to Figure 1 , this embodiment provides a continuous drying oven structure including a drying oven body 10, a air supply duct 20, a heat pump unit 30, and a return air duct 40. An air inlet 11 is provided at the bottom of the side surface of the drying oven body 10, and an air outlet 12 is provided at the top of the drying oven body 10. One end of the air supply duct 20 is communicated with the air inlet 11, the air supply port 31 of the heat pump unit 30 is communicated with the other end of the air supply duct 20, one end of the return air duct 40 is communicated with the air outlet 12, and the other end of the return air duct 40 is communicated with the return air port 32 of the heat pump unit 30.

[0036] Specifically, when the multi-layer continuous drying oven in the prior art is in use, most of them use a large fan to supply air from the bottom of one side of the drying oven and exhaust air from the top of the other side of the drying oven. After drying operation in this way, the power consumption of the fan is relatively large, which easily increases the operating energy consumption. To solve this technical problem, when the continuous drying oven structure provided in this embodiment is in use, the air supply port 31 of the heat pump unit 30 is communicated with the air inlet 11 at the bottom of the side surface of the drying oven body 10 through the air supply duct 20. The hot air of the heat pump unit 30 goes upward from the bottom of the drying oven body 10 and exchanges heat with the materials in the drying oven body 10. Finally, it flows out through the air outlet 12 at the top of the drying oven body 10. After flowing out, it can also return to the heat pump unit 30 through the return air duct 40 and continue to be used in circulation. This continuous drying oven structure sets the air outlet 12 of the drying oven body 10 at the top, which can utilize the characteristic that air goes upward to let the air flow out, can reduce the power of the fan 35, thereby reducing the operating energy consumption, saving costs, increasing the drying uniformity, and ensuring the overall operating effect.

[0037] In this embodiment, the heat pump unit 30 includes a housing 33, a heater 34, and a fan 35. The heater 34 is arranged inside the housing 33. The air supply port 31 is located at the bottom of the side wall of the housing 33, and the return air port 32 is located at the top of the housing 33. The heater 34 is used to heat the air entering the housing 33. The fan 35 is installed inside the housing 33 and is arranged at the air supply port 31. The fan 35 is used to suck the hot air in the housing 33 to the air supply port 31 and send it out through the air supply port 31. Among them, the heater 34 can heat the air entering the housing 33 to the target temperature. The fan 35 is installed at the position of the air supply port 31. After the fan 35 is started, a negative pressure is generated, sucking the hot air in the housing 33 to the air supply port 31 and sending it out. The hot air enters the air supply duct 20 through the air supply port 31 and finally reaches the drying oven body 10 for drying work.

[0038] Specifically, the heat pump unit 30 is installed on the side of the drying box body 10, and the air outlet 31 of the heat pump unit 30 and the air inlet 11 of the drying box body 10 are on the same horizontal line, thereby reducing the operating power of the fan 35.

[0039] Specifically, the continuous drying box structure further includes a conveying mesh belt 50. The conveying mesh belt 50 is arranged inside the drying box body 10 and is used to guide the hot air inside the drying box body 10 to the air outlet 12. Among them, the conveying mesh belt 50 has a number of conveying holes. When the hot air at the bottom of the drying box body 10 goes upward, it will successively pass through the conveying holes of the conveying mesh belt 50, thereby accelerating the flow speed and reducing the operating energy consumption.

[0040] It can be understood that the number of the conveying mesh belts 50 is multiple layers, and the multiple layers of conveying mesh belts 50 are arranged at intervals in the vertical direction. In this embodiment, the number of the conveying mesh belts 50 is four layers. In other embodiments, the number of the conveying mesh belts 50 can be increased or decreased, and no specific limitation is made here.

[0041] It should be noted that the continuous drying box structure further includes a fan room 60 and a circulation fan 70. The fan room 60 is located between the heat pump unit 30 and the drying box body 10, and the fan room 60 is communicated with the drying box body 10. The circulation fan 70 is installed in the fan room 60 and is used to convey the air entering the fan room 60 to the air inlet 11 of the drying box body 10.

[0042] Specifically, the fan room 60 is provided with a first opening 61 and a second opening 62. The first opening 61 and the second opening 62 are located at the top and bottom of the same side wall. The second opening 62 is communicated with the air inlet 11, and the circulation fan 70 is arranged between the first opening 61 and the second opening 62. Among them, after the circulation fan 70 is started, it can generate negative pressure, thereby sucking the air entering the fan room 60 through the first opening 61 downward and concentrating the air at the position of the second opening 62, thereby increasing the air entering the drying box body 10.

[0043] Furthermore, the fan room 60 is also provided with a third opening 63, and the third opening 63 is communicated with the air outlet 31 of the heat pump unit 30. The third opening 63 and the first opening 61 are located on opposite sides. The third opening 63 is located at the bottom of the side surface of the fan room 60, and the third opening 63 and the air outlet 31 of the heat pump unit 30 are on the same horizontal line.

[0044] In this embodiment, a partition 80 is arranged in the fan room 60. The partition 80 is installed in the middle of the fan room 60, and the circulation fan 70 is installed on the partition 80.

[0045] In this embodiment, the number of circulation fans 70 is multiple, and the multiple circulation fans 70 are arranged at intervals in the horizontal direction. Specifically, the number of circulation fans 70 is four, and the four circulation fans 70 are arranged at intervals in the horizontal direction. In other embodiments, the number of circulation fans 70 can be increased or decreased, and no specific limitation is made here.

[0046] It can be understood that the areas of the air inlet 11 and the air outlet 12 of the drying box body 10 can be designed and adjusted according to the size of the drying box body 10 and the material dehydration rate, and no specific limitation is made here.

[0047] The continuous drying box structure provided in this embodiment has at least the following advantages:

[0048] Specifically, when the multi-layer continuous drying box in the prior art is in use, most of them use a large fan to supply air from the bottom on one side of the drying box and exhaust air from the top on the other side of the drying box. After drying operations in this way, the power consumption of the fan is relatively large, which easily increases the operating energy consumption. To solve this technical problem, when the continuous drying box structure provided in this embodiment is in use, the air supply port 31 of the heat pump unit 30 is communicated with the air inlet 11 at the bottom of the side surface of the drying box body 10 through the air supply duct 20. The hot air of the heat pump unit 30 goes upward from the bottom of the drying box body 10 and exchanges heat with the materials in the drying box body 10, and finally flows out through the air outlet 12 at the top of the drying box body 10. After flowing out, it can also return to the heat pump unit 30 through the return air duct 40 and continue to circulate for use. This continuous drying box structure arranges the air outlet 12 of the drying box body 10 at the top, can utilize the characteristic that air goes upward to let the air flow out, can reduce the power of the fan 35 so as to reduce the operating energy consumption, save costs, and at the same time increase the drying uniformity and ensure the overall operating effect.

[0049] In summary, the embodiment of the present utility model provides a continuous drying box structure, which includes a drying box body 10, a air supply duct 20, a heat pump unit 30 and a return air duct 40. An air inlet 11 is provided at the bottom of the side surface of the drying box body 10, and an air outlet 12 is provided at the top of the drying box body 10. One end of the air supply duct 20 is communicated with the air inlet 11, the air supply port 31 of the heat pump unit 30 is communicated with the other end of the air supply duct 20, one end of the return air duct 40 is communicated with the air outlet 12, and the other end of the return air duct 40 is communicated with the return air port 32 of the heat pump unit 30. When in use, the air supply port 31 of the heat pump unit 30 is communicated with the air inlet 11 at the bottom of the side surface of the drying box body 10 through the air supply duct 20. The hot air of the heat pump unit 30 goes upward from the bottom of the drying box body 10 and exchanges heat with the materials in the drying box body 10, and finally flows out through the air outlet 12 at the top of the drying box body 10. After flowing out, it can also return to the heat pump unit 30 through the return air duct 40 and continue to circulate for use. The continuous drying box structure arranges the air outlet 12 of the drying box body 10 at the top, which can utilize the characteristic that air goes upward to let the air flow out, can reduce the power of the fan 35 so as to reduce the operation energy consumption, save the cost, and at the same time increase the drying uniformity and ensure the overall operation effect.
