Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, and in particular to an electric heating forced-air drying oven. Background Technology

[0002] In many industries requiring drying processes, such as chemical, pharmaceutical, food, and scientific research, electric heating drying ovens are a commonly used and important piece of equipment. They use electric heating elements to generate heat and a blower to circulate air within the oven, thereby achieving the drying process for materials. Existing technology discloses an electric thermostatic drying oven with good drying effect, application number 202123159475.X. It includes a box body, a blower mounted on the box body, and an electric heating tube located downstream of the blower's outlet end extending into the box body. The box body has a mesh plate, and a drive motor is mounted on the mesh plate. The output end of the drive motor is connected to an outer tube via a turntable. The outer tube has several placement trays of different sizes, and each placement tray has a guide structure. An inner duct is located inside the outer tube, cooperating with the guide structure. A concentrator is located in the middle of the blower's outlet end extending into the box body, and the top of the inner duct is directly below the concentrator. This invention uses a drive motor to rotate the outer tube, which in turn rotates the placement trays. The concentrator guides hot air to the inner duct, and the guide structure directs the hot air to the material on the placement trays, increasing the drying efficiency. However, the existing technology still suffers from the problem of lacking an effective drying mechanism for circulating air, resulting in increased humidity inside the box during the drying process, making it difficult to achieve the expected drying effect for humidity-sensitive materials. Therefore, we propose an electrically heated forced-air drying oven to solve the above problems. Utility Model Content

[0003] To address the shortcomings mentioned above, this invention provides an electrically heated forced-air drying oven that can effectively reduce the humidity of the circulating air inside the oven, ensuring that the expected drying effect is achieved for humidity-sensitive materials.

[0004] To solve the above problems, the technical solution provided by this utility model is as follows:

[0005] An electric heating forced-air drying oven includes a main drying chamber, a blower, and a base plate. The main drying chamber is mounted on the upper end of a mounting platform, which is fixedly mounted on the upper end of the base plate via support legs. Feed openings are provided on the left and right sides of the main drying chamber. A cover moving frame is provided on the upper end of the base plate, with two cover moving frames symmetrically arranged on the left and right sides of the main drying chamber. A cover is mounted on the cover moving frame, and a pressure block is fixedly mounted on the cover. The pressure block matches the feed opening, and a material placement groove is fixedly mounted on the pressure block. A circulating exhaust port is provided at the upper end of the main drying chamber, and a circulating air inlet is provided at the rear side of the main drying chamber. A drying mechanism is installed at the rear of the main drying chamber. The circulating exhaust port is connected to the drying mechanism via a first air duct, and the circulating air inlet is connected to the drying mechanism via a second air duct.

[0006] Furthermore, a rotating motor is installed at the lower center of the mounting platform of the box body. The output end of the rotating motor is fixedly connected to the rotating column. The upper end of the rotating column is rotatably connected to the upper end of the inner wall of the drying main box body. A heating tube mounting plate is fixedly installed on the rotating column.

[0007] Furthermore, electric heating tubes are evenly distributed on the heating tube mounting plate, and the electric heating tubes are electrically connected to an external power source.

[0008] Furthermore, the drying mechanism includes an outer shell, a flow fan, a drying filler, an upper limit baffle and a lower limit baffle, the drying filler is filled between the upper limit baffle and the lower limit baffle, and the flow fan is installed below the lower limit baffle.

[0009] Furthermore, the drying filler is made of activated alumina.

[0010] Furthermore, the blower is installed on one side of the main drying chamber, and the air outlet of the blower is connected to an air outlet hood, which is horn-shaped.

[0011] Furthermore, the lower end of the box cover moving frame is slidably connected to the base plate from left to right.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The drying unit utilizes activated alumina and a circulating fan to efficiently reduce the humidity of the circulating air, providing an ideal drying environment for humidity-sensitive materials;

[0014] 2. The rotating motor drives the heating tube mounting plate to rotate, which, together with the horn-shaped air outlet hood, enables the material to be heated evenly, accelerates the drying process, and improves drying efficiency and quality stability.

[0015] 3. The movable lid frame facilitates operation, and the pressure block enhances sealing, improving ease of use and reducing energy waste.

[0016] In summary, this type of electric heating forced-air drying oven has wide applicability, solving the problem mentioned in the background art that existing technologies still lack an effective drying mechanism for circulating air, and the humidity inside the oven increases as the drying process progresses, making it difficult to achieve the expected drying effect for humidity-sensitive materials.

Detailed Implementation

[0022] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples, but the examples given are not intended to limit the present utility model.

[0023] like Figures 1-3 As shown, the embodiment of this utility model includes a drying main chamber 1, a blower 9, and a base plate 6. The drying main chamber 1 is installed on the upper end of the chamber mounting platform 8. The chamber mounting platform 8 is fixedly installed on the upper end of the base plate 6 by support legs 7. Feed openings 101 are provided on the left and right sides of the drying main chamber 1. A cover moving frame 5 is provided on the upper end of the base plate 6. The lower end of the cover moving frame 5 is slidably connected to the base plate 6.

[0024] Blower 9 is installed on one side of the main drying chamber 1, and its function is to blow air into the main drying chamber 1. The operation of blower 9 accelerates the airflow within the main drying chamber 1, allowing heat to be transferred to the material surface more quickly, thus increasing the drying speed. The strong airflow of blower 9 effectively promotes air circulation within the main drying chamber 1, enabling hot air to quickly contact the material surface and accelerate the evaporation of moisture from the material. Simultaneously, the stable operation of blower 9 ensures the continuity and stability of airflow, thereby improving the consistency of the drying effect. The air outlet hood 11 is connected to the air outlet of blower 9 and is funnel-shaped. This shape allows the blown air to be diffused more evenly within the main drying chamber 1, enhancing airflow and further improving drying efficiency. The funnel-shaped design of the air outlet hood 11 effectively diffuses the air blown by blower 9, ensuring even air distribution within the main drying chamber 1 and preventing localized poor airflow. In this way, the material receives uniform hot air during the drying process, improving the uniformity and efficiency of drying. Meanwhile, the structural design of the air outlet shroud 11 also reduces wind resistance and improves the working efficiency of the blower 9.

[0025] Two box cover moving frames 5 are symmetrically arranged on the left and right sides of the drying main box 1. Box covers 2 are installed on the box cover moving frames 5. A pressure block 4 is fixedly installed on the box cover 2. The pressure block 4 matches the feed opening 101. A material placement trough 3 is fixedly installed on the pressure block 4. Multiple material placement troughs 3 are evenly installed on the pressure block 4 from top to bottom.

[0026] A rotating motor 10 is installed at the lower center of the mounting platform 8. The output end of the rotating motor 10 is fixedly connected to the rotating column 12. The upper end of the rotating column 12 is rotatably connected to the upper end of the inner wall of the main drying chamber 1. A heating tube mounting plate 13 is fixedly installed on the rotating column 12. Electric heating tubes 14 are evenly distributed on the heating tube mounting plate 13 and are electrically connected to an external power source. Multiple heating tube mounting plates 13 are spaced apart along the axial direction of the rotating column 12, and each heating tube mounting plate 13 is correspondingly positioned above each material placement slot 3. The rotating motor 10 is installed at the lower center of the mounting platform 8, and its output end is fixedly connected to the rotating column 12, providing rotational power to the rotating column 12. The upper end of the rotating column 12 is rotatably connected to the upper end of the inner wall of the main drying chamber 1, and multiple heating tube mounting plates 13 are fixedly installed on the column, spaced apart along the axial direction. Each heating tube mounting plate 13 is correspondingly positioned above each material placement slot 3. Electric heating tubes 14 are evenly distributed on the heating tube mounting plate 13. The electric heating tubes 14 are electrically connected to an external power source. When powered on, they generate heat. As the rotating column 12 rotates, the heat is evenly distributed into the drying main chamber 1, which heats the material efficiently and evenly.

[0027] The upper end of the main drying chamber 1 is provided with a circulating exhaust port 102, and the rear side of the main drying chamber 1 is provided with a circulating air inlet 103. A drying mechanism 15 is installed at the rear of the main drying chamber 1. The circulating exhaust port 102 is connected to the drying mechanism 15 through a first air duct 16, and the circulating air inlet 103 is connected to the drying mechanism 15 through a second air duct 17. The drying mechanism 15 includes an outer shell 1501, a circulating fan 1502, a drying packing 1503, an upper limit baffle 1504, and a lower limit baffle 1505. The drying packing 1503 is filled with... Between the upper limit baffle 1504 and the lower limit baffle 1505, a circulation fan 1502 is installed below the lower limit baffle 1505. The drying filler 1503 is made of activated alumina. The operation of the circulation fan 1502 promotes airflow. The humid air discharged from the main drying chamber 1 passes through the lower limit baffle 1505 and comes into full contact with the activated alumina. The moisture is adsorbed, thus achieving drying. Then, it passes through the upper limit baffle 1504 and enters the main drying chamber 1 again through the air duct 17 from the circulation air inlet 103 to achieve air circulation drying.
