Technical Field

[0001] This utility model relates to the technical field of heating devices for dust-free drying ovens, specifically a novel heating device for dust-free drying ovens. Background Technology

[0002] Heating systems are an essential component in the high-temperature equipment industry, and cleanroom ovens are special clean and dust-free drying equipment that provide a high-temperature purified environment.

[0003] A novel dust-free drying oven heating device (application number: 202221280125.0) utilizes a quartz heating tube short plate to fix a sealed structure, ensuring the sealing of the internal processing space and processing efficiency of the drying oven. However, the above still has its limitations. During drying operations, an oven is often used, where items are placed inside and dried by heating the heating tubes and blowing air with a fan. However, it is not convenient to blow hot air evenly on the items during drying, which can easily lead to uneven drying. Furthermore, during drying, it is necessary to expel moisture, and the exhaust port is often equipped with a filter screen, which is inconvenient for workers to disassemble and clean. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of evenly blowing hot air onto items, which easily leads to uneven drying, and the inconvenience of disassembling and cleaning the filter screen.

The air filter 11 can filter dust and impurities in the air. A tube 2 12 is fixedly connected to the inner wall of one end of the housing 10. A vertical rod 13 is fixedly connected to the top of the inner wall of the box body 1. A vertical cylinder 14 is fitted with a gap at the bottom of the outer wall of the vertical rod 13. A support plate 2 5 is fixedly connected to the bottom of one side of the vertical cylinder 14. A support plate 1 3 is fixedly connected to the rear end of the inner wall of the box body 1.

[0024] The front end of the box 1 is connected to a sliding door 4 via a hinge. A screw rod 7 is fitted into the inner wall of the outer side of one end of the box 1. A rubber sleeve is fixedly connected to the inner wall of the outer side of one end of the box 1, and the rubber sleeve serves as a seal. A filter screen 6 is fixedly connected to one end of the screw rod 7. A filter screen 9 is fitted into the outer wall of the screw rod 7. The material and mesh size of the filter screen 6 and the filter screen 9 are determined according to the actual use. A nut 8 is threadedly connected to the outer wall of the screw rod 7. A movable structure 2 is provided on one side of the shell 10. The movable structure 2 facilitates the uniform blowing of hot air on the items, thereby making the drying more uniform.

[0025] The movable structure 2 includes a threaded rod 2a1. One side of the outer wall of the threaded rod 2a1 is rotatably connected to the inner wall of one end of the housing 10 via a bearing. The bearing allows the threaded rod 2a1 to rotate on the inner wall of one end of the housing 10 when subjected to force. The top of the threaded rod 2a1 is fixedly connected to the output end of the motor 2a2. The model of the motor 2a2 depends on the actual use. The bottom of the motor 2a2 is fixedly connected to the top of the housing 10. A curved plate 2a3 is threadedly connected to the upper part of the outer wall of the threaded rod 2a1. A fan 2a5 is fixedly connected to the inner wall of one side of the curved plate 2a3. The model of the fan 2a5 depends on the actual use.

[0026] One end of the blower 2a5 is fixedly connected to the pipe body 2a6, and one end of the pipe body 2a6 is fixedly connected to the hose 2a7. One end of the hose 2a7 is fixedly connected to one end of the pipe body 12. A sliding rod 2a4 is fitted with a gap on one side of the inner wall of the curved plate 2a3. The sliding rod 2a4 limits the movement of the curved plate 2a3 when it is subjected to force. The top of the sliding rod 2a4 is fixedly connected to the top side of the inner wall of the housing 10. A heating tube 2a8 is provided on one side of the blower 2a5. The model of the heating tube 2a8 is determined according to the actual use. The top of the outer wall of the heating tube 2a8 is fixedly connected to the inner wall of the top side of the box 1, which facilitates the uniform blowing of hot air on the items, thereby making the drying more uniform.

[0027] Working principle:

[0028] When using an oven:

[0029] Open the sliding door 4, place the items on top of tray 3 and tray 5, close the sliding door 4, and the heating tube 2a8, motor 2a2, and fan 2a5 will start working. The heating tube 2a8 will heat the items, while the motor 2a2 will drive the threaded rod 2a1 to rotate. The threaded rod 2a1 will drive the curved plate 2a3 to move up and down, and the curved plate 2a3 will drive the fan 2a5 to move up and down. The air filter 11 will filter the dust in the air. The air blown by the fan 2a5 will pass through the heating tube 2a8 and then blow hot air onto the items, thus achieving dust-free drying. After drying, open the sliding door 4 and take out the items. When it is necessary to clean or replace the filter screen 6 and filter screen 9, turn the nut 8 to move the nut 8 out of the outer wall of the screw 7, move the filter screen 6 to the left, and the filter screen 6 will drive the screw 7 to move out of the inner wall of the outer side of one end of the box body 1, thus realizing the disassembly of the filter screen 6 and filter screen 9, which will facilitate the cleaning or replacement of the filter screen 6 and filter screen 9 by the staff.

[0030] Example 2:

[0031] See attached document Figure 1-6In this embodiment, a novel dust-free oven heating device is provided, wherein the movable structure 2 may further include a rod 2b4. The bottom of the rod 2b4 is fixedly connected to one side of the top of the tray 3. A frame 2b1 is fitted with the upper outer wall of the rod 2b4 with a gap. One end of the frame 2b1 is fixedly connected to the lower side of one side of the vertical cylinder 14. An insert rod 2b2 is fitted with the inner wall of the other end of the frame 2b1 with a gap. One side of the outer wall of the insert rod 2b2 is fitted with a groove on one side of the rod 2b4 with a gap. A spring 2b3 is fitted with the outer wall of the insert rod 2b2 with a gap. The spring 2b3 applies a force to the right to the insert rod 2b2. The left and right ends of the spring 2b3 are fixedly connected to one end of the inner wall of the frame 2b1 and one side of the outer wall of the insert rod 2b2, respectively.

[0032] Working principle:

[0033] The second pallet 5 is moved up and down, which in turn moves the vertical cylinder 14 up and down. After the second pallet 5 is adjusted to a suitable position, the spring 2b3 drives the insertion rod 2b2 to move to the right. The insertion rod 2b2 is inserted into the inner wall of the groove on one side of the rod body 2a4, thereby achieving the positioning of the second pallet 5. This makes it easy to adjust the position between the first pallet 3 and the second pallet 5 according to the size of the items, making it convenient for staff to place items of different sizes.
