Description

Technical Field

[0001] This utility model mainly relates to the field of thioctic acid production, specifically to a hot air circulating oven for thioctic acid. Background Technology

[0002] Alpha-lipoic acid is an organic compound that acts as a coenzyme in acyl transfer during metabolism, eliminating free radicals that accelerate aging and cause disease. After being absorbed through the intestines, alpha-lipoic acid enters cells and exhibits both lipid and water solubility.

[0003] After the production of lipoic acid, the lipoic acid powder will contain a certain amount of moisture. It needs to be dried in a hot air circulating oven to facilitate the subsequent packaging of the lipoic acid powder.

[0004] During the operation of specific embodiments, the inventors discovered the following defects:

[0005] The lipoic acid powder is directly piled up inside the heat-sealed circulating oven, causing the lipoic acid powder at the top to dry at a different rate than that at the bottom. When the lipoic acid powder at the top dries for a long time, the effective substances inside the lipoic acid powder are easily destroyed, affecting the efficacy of the lipoic acid powder.

[0006] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0008] This invention provides a hot air circulating oven for thioctic acid to solve the technical problems existing in the background art.

[0009] 2. Technical Solution:

[0010] To achieve the above objectives, the technical solution provided by this utility model is as follows: a hot air circulating oven for thioctic acid, comprising an oven shell, wherein a synchronous feeding structure is provided inside the oven shell;

[0011] A synchronous feeding structure includes a synchronous belt body, and a feeding bar is provided on the outer wall of the synchronous belt body. The number of feeding bars is set to multiple, and the multiple feeding bars are distributed at equal intervals on the outer wall of the synchronous belt body. A feeding groove is opened on one side of the feeding bar, and the feeding groove is inclined away from the synchronous belt body.

[0012] Furthermore, guide wheels are provided on both sides of the middle of the oven shell, and the outer wall of the guide wheels is slidably connected to the outer wall of the synchronous belt body.

[0013] Furthermore, a rotating shaft is provided on both sides of the inner wall of the oven shell, and a synchronous pulley is provided at both ends of the rotating shaft. The outer wall of the synchronous pulley is in contact with the inner wall of the synchronous belt body.

[0017] 3. Beneficial effects:

[0018] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0019] This invention utilizes a movable synchronous feeding structure. The synchronous belt drives the feeding bar past the bottom of the oven shell to load the bottom thioctic acid powder into the feeding trough. When the feeding trough moves to the highest point, the thioctic acid inside falls downwards and passes through the air outlet trough. The air after heating and drying is discharged through the air outlet trough and comes into contact with the thioctic acid powder. The scattered thioctic acid powder can have better contact with the air, which can quickly remove the moisture inside the thioctic acid powder and improve the drying speed of the thioctic acid powder.

[0030] See attached document Figure 1-4 A hot air circulating oven for thioctic acid includes an oven shell 1, wherein a synchronous feeding structure 5 is provided inside the oven shell 1;

[0031] The synchronous feeding structure 5 includes a synchronous belt body 501. The outer wall of the synchronous belt body 501 is provided with feeding strips 502. The number of feeding strips 502 is set to multiple. The multiple feeding strips 502 are evenly distributed on the outer wall of the synchronous belt body 501. A feeding groove 503 is opened on one side of the feeding strip 502. The feeding groove 503 is inclined away from the synchronous belt body 501.

[0032] Furthermore, guide wheels 2 are provided on both sides of the middle of the oven shell 1. The outer wall of the guide wheel 2 is slidably connected to the outer wall of the synchronous belt body 501. The guide wheel 2 can limit the synchronous belt body 501, so that the synchronous belt body 501 can move along a certain route.

[0033] Furthermore, rotating shafts 3 are provided on both sides of the inner wall of the oven shell 1, and synchronous pulleys 4 are provided at both ends of the rotating shafts 3. The outer wall of the synchronous pulleys 4 is in contact with the inner wall of the synchronous belt body 501. A servo motor 9 is provided on one side of the oven shell 1. The output end of the servo motor 9 is connected to the rotating shaft 3. When the servo motor 9 is started, the servo motor 9 drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the synchronous pulleys 4 to rotate, and the synchronous pulleys 4 drive the synchronous belt body 501 to move along a specific route. When one side of the oven shell 1... When the bottommost feeding bar 502 of the synchronous belt body 501 moves to the bottom, the feeding groove 503 inside the feeding bar 502 loads the thioctic acid powder from the bottom of the oven shell 1 into the feeding groove 503 and drives the thioctic acid powder to move upward. When the synchronous belt body 501 moves the top of the inner side of the synchronous belt body 501, the thioctic acid powder falls downward along the inclined surface of the feeding groove 503, so that the thioctic acid powder is separated from each other, which facilitates the subsequent heating and drying air to contact the thioctic acid powder and dry the thioctic acid powder.

[0034] Furthermore, a connecting pipe 6 is provided inside the oven shell 1. Air outlet grooves 7 are provided on both sides of the outer wall of the connecting pipe 6. An air pipe 8 is provided at one end of the connecting pipe 6. The air pipe 8 is attached to the outer wall of the oven shell 1. An air pump sends the dried and heated gas into the interior of the air pipe 8. Then the gas enters the interior of the connecting pipe 6 and is discharged through the air outlet grooves 7. The thioctic acid powder that falls from the interior of the oven shell 1 comes into contact with the gas, thereby quickly drying the thioctic acid powder.

[0035] Furthermore, a discharge port 13 is provided directly below the oven shell 1. Two drive screws 10 are rotatably connected to both sides of the outer wall of the oven shell 1. A sealing structure, including a sealing plate 12, is provided between the two drive screws 10. The sealing plate 12 is slidably connected to the lower part of the oven shell 1. Two sealing plates 12 are provided, and movable frames 11 are provided at both ends of the sealing plate 12. The movable frames 11 cooperate with the drive screws 10. After the thioctic acid powder inside the oven shell 1 has been processed, the motor is started. The motor drives the drive screws 10 to rotate, and the drive screws 10, through the movable frames 11, drive the sealing plates 12 to move outward, opening the discharge port 13, allowing the thioctic acid powder inside the oven shell 1 to be discharged from the interior of the oven shell 1.

[0036] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
