Description

Technical Field

[0001] This utility model relates to the field of hot air circulating oven technology, specifically a hot air circulating oven drying and sampling device. Background Technology

[0002] A hot air circulating oven is a drying device that uses heating elements and a circulating fan to continuously circulate hot air within the oven. Its main function is to evaporate excess moisture from materials with high humidity by passing them through high-temperature, high-speed hot air, thereby achieving a drying effect. It is widely used for material drying in industries such as chemical, pharmaceutical, and food.

[0003] In real life, during the drying process of materials in a hot air circulating oven, it is necessary to sample and test the materials. However, most existing sampling methods involve manually opening the oven door to take samples. This sampling process is not only inefficient, but also causes a large amount of heat to escape from the oven, thus increasing heat loss. Therefore, a hot air circulating oven drying sampling device is needed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this utility model is a hot air circulating oven drying sampling device, comprising:

[0027] The drying oven body 11 has several sampling slots 12 on one side, and a protective cover 13 is fixedly installed on the outside of the drying oven body 11 near the sampling slots 12.

[0028] The drying chamber body 11 is used for drying materials. It is equipped with heating elements (such as electric heating tubes and steam heat exchangers) and circulating fans. Through the coordinated action of the heating elements and the circulating fans, hot air is continuously circulated in the chamber, thereby evaporating excess moisture from the materials. The sampling slot 12 is used to take samples from the drying chamber body 11, and the bottom of the sampling slot 12 is at the same level as the top of each material carrier plate inside the drying chamber body 11.

[0029] The sampling component includes a servo motor 21. A lead screw 22 is fixedly provided at the output end of the servo motor 21. A rod seat 23 is provided on the outer wall of the lead screw 22. Two first electric push rods 24 are fixedly provided on the inner wall of the rod seat 23. The telescopic ends of the two first electric push rods 24 are provided with a mounting plate 25. A sampling box 26 is slidably provided on one side of the mounting plate 25.

[0030] The servo motor 21 is used to provide the driving force required for the sampling box 26 to move up and down. The servo motor 21 is fixedly installed at the top of the protective cover 13. The outer wall of the lead screw 22 passes through the top of the protective cover 13 and rotates with the protective cover 13. The bottom end of the lead screw 22 is connected to the inner bottom bearing of the protective cover 13. The first electric push rod 24 is used to provide the driving force required for the sampling box 26 to move and sample.

[0031] The heat insulation component includes several second electric push rods 31, and the telescopic end of the second electric push rods 31 is fixedly provided with a heat insulation plate 32, and one side of the heat insulation plate 32 is in contact with the groove of the sampling groove 12.

[0032] The second electric push rod 31 is used to provide the driving force required for the movement of the heat insulation plate 32. When the second electric push rod 31 is in normal state, the heat insulation plate 32 covers the sampling slot 12. When the second electric push rod 31 is extended to its maximum stroke, the heat insulation plate 32 does not contact the sampling slot 12 and is still located inside the protective cover 13. A paper control panel is installed on the other side of the drying oven body 11, and the servo motor 21, the first electric push rod 24 and the second electric push rod 31 are electrically connected to the external power supply through the control panel.

[0033] The length and height of the sampling box 26 are adapted to the length and height of the sampling slot 12, respectively;

[0034] This reduces heat loss when the sampling box 26 passes through the sampling slot 12 to take samples.

[0035] The sampling component also includes a slide bar 27, the two ends of which are fixedly connected to the upper and lower ends of the inner wall of the protective cover 13, respectively. The outer wall of the slide bar 27 penetrates the top of the rod seat 23 and slides in cooperation with the rod seat 23.

[0036] The slide bar 27 is used to guide and limit the rod seat 23, so that the rod seat 23 can move up and down along the lead screw 22.

[0037] The outer walls of several second electric push rods 31 are provided with a fixing frame 33, and the two ends of one side of the fixing frame 33 are respectively fixedly connected to one side of the protective cover 13;

[0038] The fixing frame 33 is U-shaped and is used to connect and support the second electric push rod 31, thereby improving the overall stability of the second electric push rod 31. The number of the second electric push rods 31 is matched with the number of sampling slots 12.

[0039] The outer wall of the heat insulation plate 32 extends through one side of the protective cover 13 and slides in conjunction with the protective cover 13.

[0040] Working principle: When it is necessary to sample the material inside the drying oven body 11, the servo motor 21 is turned on. The servo motor 21 drives the lead screw 22 to rotate. The rotation of the lead screw 22 drives the rod seat 23 to move downward, which in turn drives the sampling box 26 to move downward through the mounting plate 25. When the sampling box 26 moves to the height of the designated sampling slot 12, the second electric push rod 31 at the corresponding position is opened. The electric push rod 31 drives the heat insulation plate 32 to move outward, so that it opens from the sampling slot 12. Then the first electric push rod 24 is opened. The first electric push rod 24 drives the sampling box 26 to move forward, so that the sampling box 26 passes through the sampling slot 12 into the drying oven body 11 for sampling. Then the first electric push rod 24 and the second electric push rod 31 are closed respectively. In this way, automatic multi-position sampling can be realized. The entire sampling process is not only highly efficient, but also the heat insulation plate 32 at the corresponding position can be opened according to the sampling position, which greatly reduces the heat overflow from the oven and reduces heat loss.

[0041] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0042] A slide bar 28 is fixedly provided in the middle of one side of the sampling box 26. The outer wall of the slide bar 28 is slidably connected to the middle of one side of the mounting plate 25. An elastic block 29 is fixedly provided at one end of one side of the sampling box 26. The outer wall of the elastic block 29 is engaged with the other side of the mounting plate 25.

[0043] The slide bar 28 is L-shaped and is used to install and position the sampling box 26. One side of the mounting plate 25 has a groove that matches the slide bar 28, and the length of the groove is less than the height of the mounting plate 25. The other side of the mounting plate 25 has a locking hole that matches the elastic block 29.

[0044] The other side of the protective cover 13 is hinged to an insulating door 14;

[0045] The mounting plate 25 has a slot on the other side near the hot spot 14.

[0046] Working principle: After the sampling box 26 has completed sampling and reset, open the door insulation 14, then press the elastic block 29 inward and move the sampling box 26 upward until the slide bar 28 separates from the mounting plate 25. This makes it easy to disassemble the sampling box 26 and facilitates the subsequent testing of the sampled material inside.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
