Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically a high-efficiency thermal circulation oven for processing Mongolian medicine. Background Technology

[0002] Mongolian medicine's raw materials are mostly sourced from grasslands and plateaus, including herbs, animal medicines, and mineral medicines. Its preparation process is unique, involving multiple steps such as collection, processing, and compounding, resulting in various dosage forms such as pills, powders, and ointments. Mongolian medicine has significant efficacy in treating certain diseases.

[0003] The high-efficiency hot air circulation oven for Mongolian medicine processing is a special equipment used for drying medicinal materials or raw materials in the production process of Mongolian medicine. It uses a forced hot air circulation method, with a fan circulating heated air inside the oven, so that the hot air can fully contact the Mongolian medicine and achieve a fast and uniform drying effect. In the preparation process of Mongolian medicine, some intermediate or final products also need to be dried. For example, when preparing Mongolian medicine granules, it is usually necessary to dry the extracted paste to remove moisture and make a dry paste, and then carry out subsequent granulation processing.

[0004] In the drying process of Mongolian medicine after preparation, the medicinal materials are usually placed inside the drying oven for heating and drying. However, after drying, when the oven door needs to be opened to take out the medicinal materials, some of the heat inside the oven will be lost. If the heat inside the oven cannot be effectively recovered before the material removal stage, the efficiency of the heat circulation system will be reduced, which will affect the energy utilization efficiency of the entire drying process. Therefore, in order to solve the above problems, a high-efficiency heat circulation drying oven for Mongolian medicine processing is proposed. Utility Model Content

[0031] Please see Figure 1-9 This utility model provides a technical solution:

[0032] A high-efficiency thermal circulation drying oven for processing Mongolian medicine includes a controller 1, a drying chamber assembly 2, and a heating assembly 4.

A movable cylinder 24 is fixedly connected to the bottom of the pull rod 23. A linear spring 25 is fixedly connected to the top of the movable cylinder 24. A cover groove 26 is provided inside the movable cylinder 24. A cover plate 27 is fixedly connected to the front end of the upper chamber 21 by bolts. The heat preservation chamber assembly 3 includes a heat preservation chamber 31. An air pump 32 is fixedly connected to the right side of the insulation box 31.

The bottom of the heating component 4 is fixedly connected to the top of the insulation box 31.

[0033] As a further implementation of this solution, the heating component 4 includes a vertical plate 41, a track groove 42 is opened on the inner side of the vertical plate 41, a microwave generator 43 is fixedly connected to one side of the vertical plate 41, and a material plate 44 slides inside the track groove 42 opened on the vertical plate 41. Through the above settings, the Mongolian medicine can be dried, and the amount of Mongolian medicine dried in a single batch can be increased.

[0034] As a further implementation of this solution, the upper housing 21 has a through hole on the inner side near the cover plate 27, the inner side of the upper housing 21 is hollow, and the rear end of the cover plate 27 has an arc-shaped groove. The rear end of the cover plate 27 is flush with the inner side of the upper housing 21. With the above settings, when the moving cylinder 24 moves, the gas at the upper end of the moving cylinder 24 can be guided through the pressure relief hole 22 to reduce the resistance when the moving cylinder 24 moves. At the same time, the pressure relief hole 22 can penetrate the position inside the upper housing 21 where the moving cylinder 24 is located.

[0035] As a further implementation of this solution, a through hole is provided on the inner side of the cover plate 27 near the first solenoid valve 28. The first solenoid valve 28 is fixedly connected to the inner side of the through hole of the cover plate 27. A rubber ring 29 is fixedly connected to the rear end of the cover plate 27. The rear end of the rubber ring 29 fits against the front end of the upper box 21. Bolts are installed on the inner side of the cover plate 27. The bolts installed on the cover plate 27 are located on the outer periphery of the rubber ring 29. Through the above settings, the interior of the upper box 21 can be sealed. At the same time, through the setting of the first solenoid valve 28, the air pressure inside the upper box 21 is balanced when drying Mongolian medicine.

[0036] As a further implementation of this solution, the pressure relief hole 22 penetrates the upper end of the upper housing 21 and communicates with the inner side of the upper housing 21. The upper end of the linear spring 25 is fixedly connected to the inner side of the upper end of the upper housing 21. A sealing ring is fixedly connected to the outer side of the moving cylinder 24. The moving cylinder 24 fits against the inner side of the upper housing 21 through the sealing ring. The moving cylinder 24 is sleeved on the outer side of the heating component 4 through the cover groove 26. The height of the moving cylinder 24 is 1.2 times the height of the cover plate 27. Through the above settings, the moving cylinder 24 and the upper housing 21 are sealed. The rubber ring 29 is located at the upper end of the moving cylinder 24, which facilitates the entry of external gas into the lower end of the rubber ring 29 and between the moving cylinder 24 and the upper housing 21.

[0037] As a further implementation of this solution, a through hole is provided on the inner side of the insulation box 31 near the second solenoid valve 36, and an upper vent 38 is provided through the upper end of the insulation box 31. The upper vent 38 and the third solenoid valve 37 are located inside the upper box 21. The movable groove 33 is cylindrical in shape, and the movable disc 35 is cylindrical in shape. A sealing ring is fixedly connected to the outer side of the movable disc 35. The movable disc 35 fits against the inner side of the movable groove 33 in the insulation box 31 through the sealing ring. With the above settings, air can be evacuated from the inside of the movable groove 33. When negative pressure is applied, the movable disc 35 moves, thereby indirectly recovering most of the hot air inside the upper box 21.

[0038] Work process: When drying Mongolian medicine, the Mongolian medicine is evenly spread on the upper groove of the material plate 44, and then the material plate 44 is slidably installed in the rail groove 42 opened in the vertical plate 41. After the Mongolian medicine is loaded, a gap is left between multiple material plates 44. Then, the cover plate 27 is fixed to the upper box 21 with bolts. The cover plate 27 and the upper box 21 are sealed with rubber ring 29. The microwave generator 43 is started to dry the Mongolian medicine on the material plate 44 by microwave heating. At the same time, the first solenoid valve 28 is started. The first solenoid valve 28 can relieve the pressure inside the upper box 21 and prevent the upper box 21 from deforming due to thermal expansion.

[0039] While recovering some heat from the interior of the upper housing 21, and simultaneously removing the Mongolian medicine from the material plate 44 to replace it with other Mongolian medicines with drying functions, the first solenoid valve 28 closes, and the second solenoid valve 36 and the third solenoid valve 37 open. The vacuum pump 32 is activated to evacuate air from the movable groove 33. At this time, a negative pressure is generated at the lower end of the movable disc 35. Under the action of this negative pressure, the movable disc 35 moves downwards, pressing against the spring extension rod 34. This creates a negative pressure inside the upper housing 21. Under the action of this negative pressure, the moving cylinder 24 drives the pull rod 23 to move downwards, causing the linear spring 25 to extend elastically. At this time, most of the hot air inside the upper housing 21 is drawn out through the upper vent 3. 8. Push it into the interior of the movable groove 33, that is, the upper part of the movable disc 35. Observe the moving distance of the moving cylinder 24 through the pressure relief hole 22. After the moving cylinder 24 moves to the top of the heat preservation box 31, the heat recovery is completed. Then close the third solenoid valve 37 and the second solenoid valve 36. At this time, the heat is concentrated and stored in the interior of the movable groove 33, that is, the upper end of the movable disc 35. It is kept warm by the heat preservation box 31. Then open the first solenoid valve 28. The external air enters the lower end of the rubber ring 29. Under the action of the elastic tension of the linear spring 25, the moving cylinder 24 is pulled upward, so that the moving cylinder 24 is away from the heating component 4. Then open the cover plate 27 and take out the medicine inside the heating component 4.

[0040] When recycling the recovered heat, after placing the dried Mongolian medicine inside the heating component 4, the cover plate 27 is fixed to the upper box 21, the first solenoid valve 28 is opened, and the pull rod 23 is pressed down. When the bottom of the moving cylinder 24 is in contact with the top of the heat preservation box 31, the first solenoid valve 28 is closed. At this time, the rubber ring 29 is at the top of the cover plate 27. Then, the second solenoid valve 36 and the third solenoid valve 37 are opened at the same time. Under the action of the elastic force of the spring telescopic rod 34, the hot air at the top of the movable disc 35 is pushed into the upper box 21 through the upper vent 38, which is the lower end of the moving cylinder 24. At the same time as the second solenoid valve 36 is opened, the pull rod 23 is released. At this time, the hot air flows back into the upper box 21, achieving the effect of efficient heat circulation.

[0041] Based on the above principles, the device can recover heat during the process of extracting Mongolian medicine, reducing the large amount of heat loss caused by opening the box door. This not only improves the efficiency of drying Mongolian medicine, but also improves energy utilization efficiency.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
