Description

Technical Field

[0001] This application relates to the technical field of electric heating forced-air drying ovens, and in particular to a ventilation structure for an electric heating forced-air drying oven. Background Technology

[0002] Electric heating drying ovens are widely used in laboratories, industrial production, and other fields, primarily for the rapid drying of objects. Traditional electric heating drying ovens generate hot air through heating elements, which is then blown into the oven by a blower to dry the objects.

[0003] Regarding the aforementioned technologies, it has been found that existing electric heating blast drying ovens have a fixed airflow direction within the chamber, resulting in uneven distribution of hot air. This frequently leads to situations where one side of an object is thoroughly dried while the other side remains incompletely dried. This not only affects drying efficiency but may also cause damage to objects due to localized overheating or incomplete drying, reducing the applicability and reliability of the equipment. Utility Model Content

[0004] To achieve uniform drying, this application provides a ventilation structure for an electric heating drying oven.

[0005] The ventilation structure for an electric heating drying oven provided in this application adopts the following technical solution:

[0006] A ventilation structure for an electric heating drying oven includes a drying chamber assembly. The drying chamber assembly includes a main chamber shell and a sealing cover. The sealing cover is installed on the front end face of the main chamber shell, and one side of the sealing cover is rotatably connected to the main chamber shell. A hot air blower is fixedly installed on the lower end face of the main chamber shell. A diversion shell connected to the air outlet of the hot air blower is also provided in the main chamber shell. The two sides of the diversion shell are fixed to the inner side of the main chamber shell, and a positioning frame is installed above the diversion shell. The positioning frame is fixedly connected to the main chamber shell, and a plurality of air guide plate assemblies are evenly installed in the positioning frame. The lower end of the air guide plate assembly is rotatably installed in the positioning frame. A linkage component that drives the plurality of air guide plate assemblies to swing synchronously is also horizontally arranged on the main chamber shell. The linkage component is slidably connected to the main chamber shell, and an electric cylinder that drives the linkage component to move back and forth is installed on the outer side of the main chamber shell.

[0007] By adopting the above technical solution, the ventilation structure delivers hot air to the distribution shell via a hot air blower, and then guides it through the air guide plate assembly. An electric cylinder drives the linkage to move back and forth, thereby causing several air guide plate assemblies to swing synchronously, achieving flexible adjustment of the hot air ventilation direction. This design allows for a more even distribution of hot air within the drying chamber, improving the efficiency and consistency of drying results.

[0008] Optionally, the main housing includes an insulation shell and a mounting back plate, wherein the mounting back plate is installed on the rear end face of the insulation shell and is fixedly connected to the insulation shell.

[0009] By adopting the above technical solution, the main chamber shell uses a structure design of an insulated shell and a mounting back plate. The insulated shell can effectively reduce heat loss inside the drying oven and improve energy utilization efficiency. The mounting back plate facilitates the installation and fixing of the drying oven, and also facilitates the maintenance and repair of the equipment inside the drying oven.

[0010] Optionally, the diversion shell includes a main shell and a connecting bottom pipe, wherein the connecting bottom pipe is disposed on the lower end face of the main shell and is integrally formed with the main shell.

[0011] By adopting the above technical solution, the integrated design of the main shell and connecting bottom pipe of the distribution shell ensures the structural strength and sealing performance of the distribution shell. The connecting bottom pipe connects to the air outlet of the hot air blower, enabling the stable delivery of hot air to the main shell, thus providing a foundation for subsequent hot air distribution.

[0012] Optionally, a flow equalization plate is installed on the upper end face of the main housing. The flow equalization plate is sealed and fixedly connected to the main housing, and a plurality of air outlet grooves are evenly opened on the flow equalization plate.

[0013] By adopting the above technical solution, the air distribution plate installed on the upper surface of the main housing, with its evenly spaced air outlet slots, allows hot air to flow more uniformly from the distribution shell. This helps to improve the uniformity of hot air distribution within the drying chamber, further enhancing the drying effect.

[0014] Optionally, two sets of upper ear plates connected to the heat insulation shell are symmetrically installed on both sides of the upper end face of the positioning frame. The upper ear plates are fixedly connected to the positioning frame. Several connecting shafts for rotating the air guide plate assembly are also evenly installed in the positioning frame. The two ends of the connecting shafts are fixedly connected to the positioning frame.

[0015] By adopting the above technical solution, the positioning frame is fixedly connected to the insulation shell through the upper ear plate, ensuring the stability of the positioning frame. The connection shaft provides support for the rotation of the air guide plate assembly, allowing the air guide plate assembly to swing flexibly.

[0016] Optionally, the air guide plate assembly includes a vertical plate and a bushing that mates with a connecting shaft. The bushing is installed on the lower end face of the vertical plate and is integrally formed with the vertical plate.

[0017] By adopting the above technical solution, the vertical plate and bushing of the air guide plate assembly are integrally formed, ensuring the structural strength of the air guide plate assembly. The bushing cooperates with the connecting shaft, allowing the air guide plate assembly to rotate around the connecting shaft, thereby guiding the hot air.

[0018] Optionally, the linkage includes a top frame and a Y-shaped clamp. The top frame is slidably mounted on the insulation shell, and the Y-shaped clamp is evenly mounted on the lower end face of the top frame and is fixedly connected to the top frame.

[0019] By adopting the above technical solution, the top frame of the linkage is slidably mounted on the heat insulation shell, and the Y-shaped clamps are evenly mounted on the lower end face of the top frame. This structural design enables the linkage to move smoothly back and forth under the drive of the electric cylinder, and through the cooperation of the Y-shaped clamps with the positioning shaft of the air guide plate assembly, it can accurately drive the air guide plate assembly to swing synchronously.

[0020] Optionally, a positioning shaft for clamping by a Y-shaped clamp is provided in the middle of the upper surface of the upright plate, and the positioning shaft is fixedly connected to the upright plate.

[0021] By adopting the above technical solution, the positioning shaft on the upper surface of the upright plate cooperates with the Y-shaped clamp, ensuring that the linkage can effectively drive the air guide plate assembly to swing. The positioning shaft is fixedly connected to the upright plate, which improves the overall stability of the air guide plate assembly and makes the air guide plate assembly more reliable during swinging.

[0022] In summary, this application includes at least one of the following beneficial technical effects: By adjusting the oscillation of the air guide plate assembly, hot air can be blown more evenly onto the item, reducing drying dead zones, thereby improving drying efficiency and shortening drying time. The uniform hot air distribution ensures that all parts of the item are thoroughly dried, guaranteeing consistent drying results and improving product quality. The design of the heat-insulating shell reduces heat loss, lowers energy consumption, and improves energy utilization efficiency. The electric cylinder-driven linkage drives the air guide plate assembly to oscillate, allowing for flexible adjustment of the hot air ventilation direction according to different drying needs, demonstrating strong adaptability.

[0030] This application discloses a ventilation structure for an electric heating drying oven.

[0031] Reference Figure 1 , Figure 2 and Figure 3As shown, a ventilation structure for an electric heating drying oven includes a drying chamber assembly 1. The drying chamber assembly 1 includes a main chamber shell 11 and a sealing cover 12. The sealing cover 12 is installed on the front end face of the main chamber shell 11, and one side of the sealing cover 12 is rotatably connected to the main chamber shell 11. A hot air blower 2 is fixedly installed on the lower end face of the main chamber shell 11. A diversion shell 3 connected to the air outlet of the hot air blower 2 is also provided in the main chamber shell 11. The two sides of the diversion shell 3 are fixed on the inner side of the main chamber shell 11. A positioning frame 4 is installed above the diversion shell 3. The positioning frame 4 is fixedly connected to the main chamber shell 11. Several air guide plate assemblies 5 are evenly installed in the positioning frame 4. The lower end of the air guide plate assemblies 5 is rotatably installed in the positioning frame 4. A linkage 6 that drives the several air guide plate assemblies 5 to swing synchronously is also horizontally arranged on the main chamber shell 11. The linkage 6 is slidably connected to the main chamber shell 11. An electric cylinder that drives the linkage 6 to move back and forth is installed on the outer side of the main chamber shell 11. The ventilation structure delivers hot air to the distribution shell 3 via a hot air blower 2, and then guides it through the air guide plate assembly 5. An electric cylinder drives the linkage 6 to reciprocate, thereby causing several air guide plate assemblies 5 to swing synchronously, achieving flexible adjustment of the hot air ventilation direction. This design allows for a more uniform distribution of hot air within the drying chamber, improving the efficiency and consistency of drying results. The hot air blower 2 can be a common industrial model, such as the YX-2000, which has high hot air output efficiency and stability, meeting the requirements of the drying chamber. The electric cylinder can be an ANT-26 model, characterized by high precision, high speed, and long lifespan, accurately driving the linkage 6 to reciprocate. The main chamber shell 11 includes an insulation shell and a mounting back plate. The mounting back plate is installed on the rear end face of the insulation shell and is fixedly connected to it. The main chamber shell 11 adopts a structure design of an insulation shell and a mounting back plate.

The bushing 52 mates with the connecting shaft 42, allowing the air guide plate assembly 5 to rotate around the connecting shaft 42, thereby guiding the hot air. The vertical plate 51 can be made of plastic, which has the advantages of being lightweight and low-cost.

[0035] Reference Figure 5As shown, the linkage 6 includes a top frame 61 and a Y-shaped clamp 62. The top frame 61 is slidably mounted on the insulation shell, and the Y-shaped clamp 62 is evenly mounted on the lower end face of the top frame 61 and is fixedly connected to the top frame 61. This structural design allows the linkage 6 to move smoothly back and forth under the drive of the electric cylinder, and through the cooperation of the Y-shaped clamp 62 with the positioning shaft 511 of the air guide plate assembly 5, it can accurately drive the air guide plate assembly 5 to swing synchronously.

The positioning shaft 511 can be made of stainless steel bar.

[0036] The implementation principle of the ventilation structure for an electric heating drying oven according to an embodiment of this application is as follows: During actual use, the hot air blower 2 is started, and the hot air blower 2 delivers hot air to the main housing 31 of the distribution shell 3 through the connecting bottom pipe 32. The hot air flows out evenly through the air outlet groove 331 on the flow equalization plate 33 and blows onto the air guide plate assembly 5. The electric cylinder is started, driving the top frame 61 of the linkage 6 to reciprocate on the heat insulation shell. The top frame 61 drives the air guide plate assembly 5 to swing synchronously around the connecting shaft 42 through the Y-shaped clamp 62, thereby adjusting the direction of hot air ventilation and making the hot air more evenly distributed inside the drying oven for drying the items.
