Description

Technical Field

[0001] This utility model relates to the field of forced-air drying oven technology, and in particular to a centrifugal turbulence energy-saving forced-air drying oven. Background Technology

[0002] Drying ovens are divided into two main categories based on the type of material being dried: electric heating forced-air drying ovens and vacuum drying ovens. They are now widely used in industries such as chemical, electronic communications, plastics, cables, electroplating, hardware, automotive, optoelectronics, rubber products, molds, spraying, printing, medical, aerospace, and higher education.

[0003] Patent application CN221484020U discloses an energy-saving forced-air drying oven, comprising a chamber body. A controller and a blower are respectively installed on one outer wall of the chamber body, and an electric heating wire and a supporting side plate are respectively installed on the other inner wall of the chamber body. A fixed top plate is fixedly connected to the top of the supporting side plate, and a fixed bottom plate is fixedly connected to the bottom of the supporting side plate. A fixed partition is fixedly connected to the inner wall of the supporting side plate. A drive motor is fixedly connected to the inner wall of the chamber body, and the drive shaft of the drive motor is fixedly connected to a drive shaft via a coupling. This energy-saving forced-air drying oven, through its chamber body, controller, blower, electric heating wire, supporting side plate, fixed top plate, fixed bottom plate, and fixed partition, facilitates uniform flow of heating gas inside, thereby ensuring effective drying and avoiding the problem of slow drying efficiency caused by obstruction of heating gas.

[0004] However, the blower in this energy-saving blower drying oven is directly installed on the top of the inner wall of the oven. This direct exposure to the inside of the oven may pose a safety hazard to operators when maintaining or inspecting the equipment, such as being caught or injured by rotating parts. To address the above issues, we have introduced a centrifugal turbulence energy-saving blower drying oven. Utility Model Content

[0005] This utility model discloses a centrifugal turbulence energy-saving forced-air drying oven, which improves upon the existing structure and deficiencies mentioned above, and provides a centrifugal turbulence energy-saving forced-air drying oven to achieve better practical value.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A centrifugal turbulence energy-saving forced-air drying oven includes a drying oven body. A controller and a blower are respectively installed inside the drying oven body. A door is rotatably connected to one side of the drying oven body. Placement plates are equidistantly slidably connected inside the drying oven body. A limit component is provided on one side of the placement plate. A protective frame is fixedly connected inside the drying oven body. A motor is installed at the bottom of the inner wall of the drying oven body. A first blade is fixedly connected to the top of the motor's output shaft. A mounting rod is rotatably connected to the bottom of the inner wall of the drying oven body. A second blade is fixedly connected to the top of the mounting rod.

A fixing component is installed inside the protective frame to fix the top plate.

[0008] In a preferred embodiment, the fixing component includes a connecting rod, which is fixedly connected at equal intervals to one side of the inner wall of the protective frame. A retaining plate is slidably connected to the outer side of the connecting rod. A through groove is provided on the top of the top plate. The bottom of the retaining plate contacts the bottom of the inner wall of the through groove. A limit block is fixedly connected to one end of the connecting rod, and a first spring is provided on the outer side of the connecting rod.

[0009] In a preferred embodiment, the top of the card plate is provided with a slope.

[0010] In a preferred embodiment, the limiting component includes a slider, wherein a groove is formed on one side of the inner wall of the drying oven body, and the outer side of the slider is slidably connected to the inside of the groove.

[0011] In a preferred embodiment, two mounting blocks are fixedly connected to the top of the slider, and a movable rod is slidably connected inside the two mounting blocks. A locking block is fixedly connected to one end of the movable rod, and the bottom of the locking block is slidably connected to the top of the slider. A slot is provided at equal intervals on one side of the inner wall of the groove, and the bottom of the locking block abuts against the bottom of the inner wall of the slot. A second spring is provided on the outer side of the movable rod.

[0012] In a preferred embodiment, the top of the card block and the top of the inner wall of the card slot are both set as slopes.

[0013] In a preferred embodiment, the interior of the cabinet door is provided with an observation window.

[0014] The centrifugal turbulence energy-saving forced-air drying oven provided by this utility model has the following advantages:

[0015] Firstly, placing the motor and fan blades at the bottom and enclosing them in a protective frame can effectively reduce the risk of operators being injured by rotating parts during daily use and maintenance, thus improving the safety of the equipment. By setting fixed components, maintenance personnel can quickly install and remove the top plate, facilitating the maintenance of the motor and fan blades and reducing the complexity and time cost of maintenance. Placing the motor and fan blades at the bottom can accelerate the flow of hot air inside the drying chamber.

[0016] Secondly, by setting a limiting component, when adjusting the height of the placement plate, simply push the placement plate upwards. Utilizing the action of the top of the locking block against the top inclined surface of the inner wall of the slot, the locking block moves backwards, compressing the second spring. The locking block and slot are then misaligned. The placement plate is then moved to the designated height position. Under the rebound of the second spring, the locking block is pushed back into another slot to support the placement plate. Users can easily adjust the height of the placement plate according to materials with different characteristics and volume requirements to meet various drying needs, thus improving the adaptability of the equipment.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] The centrifugal turbulence energy-saving forced-air drying oven disclosed in this utility model is mainly used in forced-air drying oven scenarios.

[0028] Reference Figures 1 to 8 A centrifugal turbulence energy-saving blower drying oven includes: a drying oven body 1, a controller 2 and a blower 3 respectively installed inside the drying oven body 1, a door 4 rotatably connected to one side of the drying oven body 1, a placement plate 5 slidably connected at equal intervals inside the drying oven body 1, a limit component installed on one side of the placement plate 5, a protective frame 6 fixedly connected inside the drying oven body 1, a motor 7 installed at the bottom of the inner wall of the drying oven body 1, a first fan blade 8 fixedly connected to the top of the output shaft of the motor 7, an installation rod 9 rotatably connected to the bottom of the inner wall of the drying oven body 1, a second fan blade 10 fixedly connected to the top of the installation rod 9, a first gear 11 fixedly connected to the outside of the output shaft of the motor 7, a second gear 12 fixedly connected to the outside of the installation rod 9, the first gear 11 and the second gear 12 meshing, a heating wire 13 installed inside the protective frame 6, a top plate 14 installed at the top of the protective frame 6, and a fixing component installed inside the protective frame 6 for fixing the top plate 14.

[0029] The fixing component includes a connecting rod 15, which is fixedly connected to one side of the inner wall of the protective frame 6 at equal intervals. A retaining plate 16 is slidably connected to the outer side of the connecting rod 15. A through groove 17 is opened on the top of the top plate 14. The bottom of the retaining plate 16 contacts the bottom of the inner wall of the through groove 17. A limit block 18 is fixedly connected to one end of the connecting rod 15. A first spring 19 is provided on the outer side of the connecting rod 15.

[0030] The top of the card plate 16 is provided with a slope.

[0031] In the above technical solution, considering that the blower in the energy-saving forced-air drying oven is directly installed on the top of the inner wall of the oven, which is directly exposed inside the oven, it may cause safety hazards for operators when maintaining or inspecting the equipment, such as being caught or injured by rotating parts. To solve this problem, the specific operation is as follows: the motor 7 and the fan blades are installed at the bottom of the drying oven body 1, and then a protective frame 6 is installed on its outside to cover the motor 7 and the fan blades. At the same time, using the fixing components, the top plate 14 can be quickly installed on the protective frame 6 to completely cover the motor 7 and the fan blades. To prevent operators from injuring the rotating fan blades while using the drying oven, during maintenance, simply move the clamping plate 16 to one side of the through slot 17, then lift the top plate 14 upwards to maintain the motor 7 and fan blades. After maintenance, align the top plate 14 with the protective frame 6 and press the top plate 14 downwards. The corner of the through slot 17 will contact the inclined surface of the top of the clamping plate 16, thus pushing the clamping plate 16 open. The first spring 19 will be compressed, and the top plate 14 will fit against the protective frame 6. Under the rebound of the first spring 19, the clamping plate 16 and the through slot 17 will be pressed together, restricting the top plate 14. Placing the motor 7 and fan blades at the bottom and enclosing them in the protective frame 6 effectively reduces the risk of operators being injured by rotating parts during daily use and maintenance, improving equipment safety. By setting fixed components, maintenance personnel can quickly install and remove the top plate 14, facilitating maintenance of the motor 7 and fan blades and reducing maintenance complexity and time costs. Placing the motor 7 and fan blades at the bottom accelerates the flow of hot air inside the drying chamber. The drying chamber uses centrifugal turbulence technology, generating a powerful airflow through a high-speed rotating centrifugal fan to form an internally circulating drying environment.

[0032] Reference Figures 1 to 8In a preferred embodiment, the limiting component includes a slider 20. A groove 21 is formed on one side of the inner wall of the drying oven body 1. The outer side of the slider 20 is slidably connected to the inside of the groove 21. Two mounting blocks 23 are fixedly connected to the top of the slider 20. A movable rod 24 is slidably connected inside the two mounting blocks 23. One end of the movable rod 24 is fixedly connected to a locking block 25. The bottom of the locking block 25 is slidably connected to the top of the slider 20. A slot 22 is equidistantly formed on one side of the inner wall of the groove 21. The bottom of the locking block 25 abuts against the bottom of the inner wall of the slot 22. A second spring 26 is provided on the outer side of the movable rod 24. The top of the locking block 25 and the top of the inner wall of the slot 22 are both sloped.

[0033] In the above technical solution, considering the problem that the distance between the partitions in the drying oven cannot be adjusted, the specific operation is as follows: By setting a limiting component, when adjusting the height of the placement plate 5, simply push the placement plate 5 upwards. Utilizing the action of the top of the locking block 25 against the top inclined surface of the inner wall of the slot 22, the locking block 25 moves backwards, the second spring 26 is compressed, and the locking block 25 is misaligned with the slot 22. Then, move the placement plate 5 to the designated height position. Under the rebound of the second spring 26, the locking block 25 will be pushed back into another slot 22 to support the placement plate 5. Users can conveniently adjust the height of the placement plate 5 according to materials with different characteristics and volume requirements to meet various drying needs and improve the adaptability of the equipment.

[0034] Reference Figures 1 to 8 In a preferred embodiment, an observation window 27 is provided inside the door 4;

[0035] Working principle: In use, the motor 7 and fan blades are installed at the bottom of the drying chamber body 1, and then a protective frame 6 is installed on its outside to cover the motor 7 and fan blades. At the same time, using the fixing components, the top plate 14 can be quickly installed on the protective frame 6 to completely cover the motor 7 and fan blades, preventing the operator from being injured by the rotating fan blades when using the drying chamber. During maintenance, simply move the clamping plate 16 to one side of the through slot 17, and then lift the top plate 14 upwards to maintain the motor 7 and fan blades. After maintenance, align the top plate 14 with the protective frame 6 and press the top plate 14 downwards. The corner of the through slot 17 will contact the inclined surface of the top of the clamping plate 16, thereby pushing the clamping plate 16 open. The first spring 19 will be compressed, and the top plate 14 will fit against the protective frame 6. Under the rebound of the first spring 19, the clamping plate 16 and the through slot 17 will be pressed together, restricting the top plate 14.
