[0004] The drying device blows gas out through the first through hole for drying, but the first through hole is fixed in position on the support, causing the air to be blown in the same place, resulting in uneven drying.

[0005] To address the aforementioned problems, this utility model proposes an argon-protected drying oven. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes an argon-protected drying oven.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a drying box, in which a rotating drum is rotatably arranged at the bottom, and two air outlets are fixedly connected to the top of the rotating drum, and a rotating assembly is provided on the rotating drum; The drying oven has two air inlets on one side. One air inlet is connected to the inner cavity of the two air outlets, and the other air inlet is connected to the inner cavity of the rotating drum. A placement frame is horizontally slidably installed at the top of the drying oven, and the placement frame is movably positioned between two air outlets. An exhaust assembly is installed at the top of the drying oven, and electric heating elements are installed on the inner wall of the drying oven.

[0008] Furthermore, the interior of the drying oven is fixedly connected with a first partition and a second partition from top to bottom, and the rotating drum is rotatably connected to the top of the second partition, with the top of the rotating drum rotating through the first partition.

[0009] Furthermore, the cavity between the first partition and the second partition is a second cavity, and the air inlet communicating with the air outlet is opened on the side of the second cavity. The cavity between the second partition and the bottom surface of the drying oven is the first cavity, and the air inlet connected to the rotating drum is opened on the side of the first cavity. A three-way pipe is fixedly connected to one side of the drying oven, and two ends of the three-way pipe are fixedly connected to two air inlets respectively.

[0010] Furthermore, the two air outlets are arranged in a circumferential array about the rotating cylinder, and several air outlet holes are opened on the side of the two air outlets that are close to each other. The top of the rotating drum is provided with through holes at both air outlets. The top of the through holes is connected to the corresponding air outlets, and the bottom of the through holes is connected to the second cavity.

[0012] Furthermore, the exhaust assembly includes a fan, and an air outlet is provided in the middle of the top surface of the drying chamber. A crossbar is fixedly connected inside the air outlet, and the fan is fixedly installed on the crossbar.

[0013] Furthermore, a drying chamber is fixedly connected to the top surface of the drying chamber at the air outlet, the air outlet is connected to the inner cavity of the drying chamber, and an exhaust pipe is fixedly connected to the top of the drying chamber.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: As Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: an argon-protected drying oven, including a drying oven 1, with a rotating drum 11 rotatably arranged at the bottom of the drying oven 1, and two air outlets 19 fixedly connected to the top of the rotating drum 11. This causes the two air outlets 19 to rotate when the rotating drum 11 rotates.

[0023] The two air outlets 19 are arranged in a circumferential array about the rotating cylinder 11, and several air outlet holes are opened on the side of the two air outlets 19 that are close to each other. The top of the air outlet 19 is sealed, so that the gas inside the air outlet 19 can only be discharged from the air outlet holes.

[0024] The interior of the drying oven 1 is fixedly connected from top to bottom to a first partition 10 and a second partition 12. A rotating drum 11 is rotatably connected to the top of the second partition 12, and the top of the rotating drum 11 rotates through the first partition 10. The rotating drum 11 is positioned.

[0025] The drying oven 1 has two air inlets on one side. One air inlet is connected to the inner cavity of the two air outlets 19, and the other air inlet is connected to the inner cavity of the rotating drum 11.

[0026] The cavity between the first partition 10 and the second partition 12 is the second cavity 18, which is the cavity on the outer surface of the rotating cylinder 11. An air inlet communicating with the air outlet 19 is opened on the side of the second cavity 18, allowing gas from the second cavity 18 to enter the two air outlets 19.

[0027] The top of the rotating drum 11 has through holes 20 at both air outlets 19. The top of the through hole 20 communicates with the corresponding air outlet 19, and the bottom of the through hole 20 communicates with the second cavity 18. The through holes 20 facilitate the second cavity 18 to exhaust air into the two air outlets 19.

[0028] The cavity between the second partition 12 and the bottom surface of the drying chamber 1 is the first cavity 17, and the air inlet communicating with the rotating drum 11 is opened on the side of the first cavity 17, so that the gas in the first cavity 17 can enter the rotating drum 11.

[0029] An air inlet 25 is provided in the middle of the second partition 12. The air inlet 25 is coaxially arranged with the rotating cylinder 11, and the diameter of the air inlet 25 is smaller than the inner wall diameter of the rotating cylinder 11. This allows the first cavity 17 to breathe into the rotating cylinder 11 through the air inlet 25.

[0030] A three-way pipe 16 is fixedly connected to one side of the drying oven 1, and two ends of the three-way pipe 16 are fixedly connected to two air inlets respectively.

[0031] The other end of the three-way pipe 16 is connected to a gas source, so that the gas source can be introduced into the drying oven 1 from the two air inlets through the three-way pipe 16. The gas source in this application is argon. Argon has stable chemical properties. After heating, it can evenly transfer heat to the surface of the object through thermal conduction. At the same time, it replaces the air to form an oxygen-free environment, preventing oxidation reaction and protecting the object.

[0032] A rotating assembly is provided on the rotating drum 11.

[0033] The rotating assembly includes a fan blade 14. A fixing rod 13 is fixedly connected to the bottom end of the rotating cylinder 11, and the fixing rod 13 is horizontally arranged. A connecting shaft is fixedly connected to the middle of the bottom surface of the fixing rod 13, and the fan blade 14 is fixedly connected to the bottom end of the connecting shaft. Both the connecting shaft and the fan blade 14 extend into the air inlet 25. When gas is blown into the air inlet 25, the gas will cause the fan blade 14 to rotate, thereby causing the connecting shaft, the fixing rod 13, and the rotating cylinder 11 to rotate.

[0034] A placement frame 8 is horizontally slidably installed at the top of the drying oven 1, and the placement frame 8 is movably positioned between two air outlets 19. This allows the two air outlets 19 to blow air into the placement frame 8.

[0035] The placement frame 8 is a mesh structure woven from several metal wires. The mesh structure allows gas to enter the placement frame 8, thereby drying the objects inside.

[0036] A partition net 21 is fixedly connected to the top of the rotating drum 11, and a placement frame 8 is movably positioned above the partition net 21. This allows the rotating drum 11 to discharge air evenly through the partition net 21.

[0037] Two limiting plates 6 are fixedly connected from top to bottom on each of the two inner walls of the drying oven 1. The two lower limiting plates 6 are located above the air outlet 19.

[0038] Two connecting rods are fixedly connected to the two ends of the two sides corresponding to the top of the placement frame 8. The ends of the two connecting rods on the same side of the placement frame 8 are fixedly connected to the same sliding plate 7. The sliding plate 7 is slidably positioned between the two corresponding limiting plates 6. The placement frame 8 is positioned inside the drying oven 1 by the cooperation of the sliding plate 7 and the two limiting plates 6.

[0039] An opening is provided on one side of the drying oven 1, and a door 2 is hinged to the opening on one side of the drying oven 1. The placement frame 8 can be removed from the drying oven 1 by opening the door 2.

[0040] Two sliding plates 7 are fixedly connected to the same pull rod 9 at the end near the opening, so as to move the placement frame 8 by means of the pull rod 9. After the placement frame 8 is moved into the drying chamber 1, the chamber door 2 is closed, and the chamber door 2 will abut against one side of the pull rod 9, thereby fixing the position of the placement frame 8.

[0041] An exhaust system is installed at the top of the drying oven 1.

[0042] The exhaust assembly includes an exhaust fan 22. An air outlet is located in the center of the top surface of the drying chamber 1, and a crossbar is fixedly connected inside the air outlet. The exhaust fan 22 is fixedly mounted on the crossbar. The exhaust fan 22 utilizes the principle of airflow generated by the rotation of an impeller via a motor to achieve exhaust or ventilation. The exhaust fan 22 is an existing product.

[0043] A drying chamber 3 is fixedly connected to the top surface of the drying chamber 1 at the air outlet, and the air outlet communicates with the inner cavity of the drying chamber 3. An exhaust pipe 4 is fixedly connected to the top of the drying chamber 3. This allows the gas inside the drying chamber 1 to be discharged into the drying chamber 3 through the air outlet, and the gas inside the drying chamber 3 to be discharged through the exhaust pipe 4.

[0044] The interior of the drying chamber 3 is fixedly connected with several filter plates at intervals from top to bottom, and each filter plate is topped with a drying absorbent cotton 5. The drying absorbent cotton 5, through its porous structure, can absorb moisture from the gas, thus achieving a drying effect.

[0045] A transparent window is hinged to the side of the drying oven 3 so that the drying absorbent cotton 5 can be viewed through the window and replaced in a timely manner.

[0046] An electric heating element 15 is installed on the inner wall of the drying oven 1. The electric heating element 15 is an electric heating device in which a resistance heating wire is wound around a mica plate, and it is an existing product.

[0047] Working principle: To use, open the door 2. Pull the lever 9 to move the lever 9 and the slide plate 7 out of the drying chamber 1. After moving part of the placement frame 8 out of the drying chamber 1, place the object inside the placement frame 8, and then push the placement frame 8 back into the drying chamber 1.

[0048] Alternatively, the placement frame 8 can be moved directly out of the drying oven 1. After placing the object, the slide plate 7 can be moved back between the two corresponding limit plates 6 to install the placement frame 8.

[0049] Close the door 2 and position the placement frame 8 between the two air outlets 19 to seal the drying chamber 1. Power on the electric heating element 15 to raise the temperature inside the drying chamber 1.

[0050] Connect one end of the three-way pipe 16 to argon gas, and the argon gas will enter the first cavity 17 and the second cavity 18 through the two gas inlets.

[0051] The gas entering the second chamber 18 passes through the through hole 20 into the two air outlets 19, which then blow the gas towards the side of the placement frame 8 through their outlet holes. This dries the object from the side.

[0052] Gas entering the first chamber 17 enters the rotating drum 11 through the air inlet 25, and then passes through the partition 21 and is blown toward the bottom surface of the placement frame 8. Thus, the object is dried from the bottom.

[0053] When the gas passes through the air inlet 25, it will cause the fan blades 14 to rotate, which in turn drives the fixed rod 13 and the rotating cylinder 11 to rotate. This causes the two air outlets 19 to rotate, allowing them to blow air onto different parts of the object's side, ensuring that the object receives airflow evenly.

[0054] Start the exhaust fan 22. The exhaust fan 22 will circulate the dried gas into the drying chamber 3, allowing the drying absorbent cotton 5 to dehumidify the gas. The gas will then be discharged from the exhaust pipe 4.

[0055] Example 2: Figures 5-6 As shown, the difference between this embodiment and Embodiment 1 is that the rotating assembly includes several blades 24, which are evenly distributed circumferentially and fixedly connected to the outer surface of the rotating cylinder 11. An inclined air-blowing pipe 23 is fixedly connected to the air inlet at the second cavity 18, with the end of the air-blowing pipe 23 facing the blades 24. The air-blowing pipe 23 facilitates the blowing of gas onto the blades 24, causing the blades 24 to move and thus driving the rotating cylinder 11 to rotate.

[0056] Working principle: When air is blown into the drying oven 1 through the three-way pipe 16, the gas enters the second chamber 18 through the air blowing pipe 23. The air blowing pipe 23 blows the gas toward the blades 24, causing the blades 24 to move, thereby driving the rotating drum 11 to rotate. This causes the two air outlets 19 to rotate, blowing air onto different parts of the side of the object, ensuring that the object receives air evenly.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
