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] An electric heating drying oven, also known as a "drying oven," uses electric heating for circulating air drying experiments. It comes in two types: forced-air drying and vacuum drying. Forced-air drying uses a circulating fan to blow hot air, maintaining a balanced temperature inside the oven. Vacuum drying uses a vacuum pump to extract air from the oven, lowering the atmospheric pressure below normal, ensuring the product is tested in a very clean environment. It is a commonly used instrument, primarily for drying samples, and can also provide the necessary temperature environment for experiments. Drying ovens are used in various industries such as chemical, pharmaceutical, casting, automotive, food, and machinery. They are generally available with galvanized steel or stainless steel inner liner, pointer or digital display models, natural convection or forced-air circulation models, and conventional or vacuum types.

[0003] In existing electric heating forced-air drying ovens, the internal mesh panels are usually fixed during actual use. However, the size and shape of the medicinal materials are not uniform, which makes it inconvenient to adjust the number and spacing of the mesh panels according to the usage requirements, affecting the drying efficiency and causing inconvenience during use. Therefore, we propose an electric heating forced-air drying oven to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where, in actual use, the mesh panels inside the drying oven are usually fixed, while the size and shape of the medicinal materials are not uniform. This makes it inconvenient to adjust the number and spacing of the mesh panels according to usage needs, affecting drying efficiency and causing inconvenience during use. Therefore, an electric heating forced-air drying oven is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electric heating forced-air drying oven, comprising

[0007] Drying oven;

[0008] The equipment comprises guide strips, a fixed frame, a push plate, a transmission plate, insert blocks, and a mesh plate. There are two guide strips and two insert blocks. The fixed frame is slidably connected to the inner wall of the drying oven. The two guide strips are symmetrically fixed to the inner wall of the drying oven, and both guide strips penetrate the fixed frame. The push plate is slidably connected to the bottom of the fixed frame, and the top of the push plate extends into the interior of the fixed frame. The transmission plate is slidably connected to the inner wall of the fixed frame, and the bottom of the transmission plate is fixedly connected to the top of the push plate. The mesh plate is fixedly connected to the inner wall of the fixed frame. Multiple slots are equally spaced on the front sides of the two guide strips, and the two insert blocks engage with corresponding slots.

[0009] A fixing mechanism is connected to the insert block, and the fixing mechanism is used to move the insert block to fix the fixing frame.

The rear sides of the two sliding plates are fixedly connected to the front sides of the corresponding insert blocks.

[0012] As a preferred embodiment of this utility model, hollow plates are symmetrically fixedly connected to the inner wall of the fixed frame, and there are two hollow plates. The inner walls of the two hollow plates are slidably connected to the outer walls of the corresponding connecting rods.

[0032] As a preferred embodiment of this utility model, the fixing mechanism includes: two push rods 6, two connecting rods 7, two pressure rods 9, two sliding rods 10, and two sliding plates 11;

[0033] Two push rods 6 are rotatably connected to the top of the corresponding transmission plate 5. Two connecting rods 7 are symmetrically slidably connected to the inner wall of the fixed frame 3, and the tops of the two connecting rods 7 are rotatably connected to the bottoms of the corresponding push rods 6. Two sliding rods 10 are symmetrically slidably connected to the inner wall of the fixed frame 3. Two pressure rods 9 are rotatably connected to the tops of the corresponding sliding rods 10, and the bottoms of the two pressure rods 9 are rotatably connected to the tops of the corresponding connecting rods 7. Two sliding plates 11 are symmetrically slidably connected to the inner wall of the fixed frame 3, and the front sides of the two sliding plates 11 are connected to the corresponding sliding rods 10. The rear side is fixedly connected, and the rear side of the two slide plates 11 is fixedly connected to the front side of the corresponding insert block 13. When the transmission plate 5 moves, it will push the two push rods 6. When the push rods 6 move, they will push the two connecting rods 7 to move away from each other and push the pressure rod 9. At this time, the pressure rod 9 will push the two slide rods 10 to move forward. The slide rods 10 will pull the slide plate 11 forward. When the slide plate 11 moves, it will compress the push spring 12 and drive the insert block 13 to move forward into the fixed frame 3.

[0038] It should be noted that the specific model of drying oven 1 to be used is to be selected by those skilled in the art, and the above-mentioned drying oven 1 and other related technologies are all existing technologies, which will not be elaborated upon in this solution.

[0039] The working principle of this utility model is as follows: In actual use, when drying the corresponding medicinal materials, first open the drying chamber 1, then insert the fixing frame 3 into the drying chamber 1. Next, push the push plate 4 backward. As the push plate 4 moves backward, it will cause the transmission plate 5 to move accordingly. At this point, the fixing frame 3 can be fitted onto the outer wall of the guide strip 2. By pushing the fixing frame 3, it can slide up and down on the inner wall of the drying chamber 1. When the fixing frame 3 moves to the appropriate position, release the push plate 4. The two return springs 8, no longer restrained, push the two connecting rods 7 to move closer together. The movement of the connecting rods 7 will push the two push rods 6. When push rod 6 moves, it pushes transmission plate 5 forward. The forward movement of transmission plate 5 drives push plate 4 forward to reset. At the same time, the movement of connecting rod 7 pulls two pressure rods 9, and pushes spring 12 to lose its restraint and push slide plate 11 backward. The movement of slide plate 11 drives insert block 13 backward. Insert block 13 moves and engages with slot to fix fixed frame 3 in the current position. By repeating the above steps, multiple fixed frames 3 can be installed on the inner wall of drying chamber 1 according to usage requirements, and the spacing of fixed frames 3 can be adjusted. At this time, the medicinal materials to be dried can be placed on mesh plate 14. By closing drying chamber 1 and starting it, the medicinal materials can be dried.
