Description

Technical Field

[0001] This application relates to the field of traditional Chinese medicine preparation technology, and in particular to a calcination machine for traditional Chinese medicinal materials. Background Technology

[0002] Calcining refers to the process of placing cleaned Chinese herbs in a suitable refractory container and heating them at high temperatures until they are red-hot or brittle. Therefore, a suitable refractory container that can withstand high temperatures is required. However, if too much Chinese herb is added, it will accumulate to a certain height inside the refractory container, causing the herbs closer to the heat source to be heated excessively while those farther away from the heat source are heated insufficiently. This uneven heating affects the efficacy of the Chinese herb.

[0003] Regarding calcination machines for Chinese medicinal herbs, there are many existing technologies, such as:

[0004] Chinese patent application CN201820883501.2 discloses a traditional Chinese medicine calcination machine. The calcination machine includes a calcination chamber, a chamber cover, and a spiral lifting device. The chamber cover is installed on top of the calcination chamber during calcination. The spiral lifting device includes a spiral motor and a vertical spiral body. The spiral motor drives the vertical spiral body to rotate, and the vertical spiral body is disposed inside the chamber cover. The spiral lifting device is configured such that during calcination, the vertical spiral body transports the medicinal materials at the bottom of the calcination chamber upwards. There is a gap between the vertical spiral body and the inner wall of the calcination chamber. This invention, by setting a spiral lifting device in the calcination chamber, achieves vertical rotation of the medicinal materials, ensuring uniform heating of the medicinal materials in the calcination chamber. This solves the problem of over-calcination of the bottom medicinal materials and under-calcination of the upper surface medicinal materials during calcination, thus improving the calcination effect of the medicinal materials.

[0005] The integrated design of the calcination container in the calcination machine makes cleaning the container inconvenient and cumbersome. It also results in some Chinese medicine residue remaining in the container and stirring device. If not cleaned in time, the residue will cause the medicine to be impure during the next calcination, affecting its medicinal properties. In view of this, we propose a Chinese medicinal herb calcination machine. Utility Model Content

[0026] 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.

[0027] Please see Figures 1-5 As shown, this embodiment provides a calcining machine for Chinese medicinal materials, including a calcining machine body 1. Medicinal materials are placed into the calcining machine body 1 for calcination. If the calcining machine is cumbersome to operate, requiring multiple steps and wasting manpower, and if the medicinal materials are incorrectly combined, other effects may occur, affecting the medicinal properties, the surface with remaining medicinal materials must be cleaned promptly after calcination to prevent the residue from affecting the medicinal properties during the next calcination. Therefore, specifically: the calcining machine body 1 is hollow inside and has a pull-out cavity 5 on the first side. Using the pull-out cavity 5 reduces the user's operation when using the calcining machine; only a pulling action is required.

[0028] First, the specific structure of the pull-out cavity 5 is disclosed. A baffle 50 is welded to the right side of the pull-out cavity 5. A hollow cavity 51 is welded to the middle of the side of the baffle 50 near the main body 1 of the calcining machine. A concave groove 510 is fixedly installed on the bottom of the inner side of the hollow cavity 51. A calcining barrel 52 is provided inside the hollow cavity 51. A protrusion 520 is provided at the bottom of the calcining barrel 52. The calcining barrel 52 is embedded in the concave groove 510 through the protrusion 520. By embedding the calcining barrel 52 in the concave groove 510 through the protrusion 520, the calcining barrel 52 can be disassembled, which is convenient for users to clean the calcining barrel 52.

[0029] The improvement in this embodiment is that a pull-out cavity 5 is set inside the calcining machine body 1, and a detachable calcining barrel is set inside the pull-out cavity 5, which is convenient for users to operate and can also clean up the residue of medicinal materials in a timely manner.

[0030] Considering the difficulty for users to move the calcining machine body 1 and the pull-out cavity 5, the following measures are taken: four rectangular pulleys 11 are fixedly installed circumferentially on the inner wall of the calcining machine body 1; two symmetrically distributed handles 12 are fixedly installed at the top of the second side of the calcining machine body 1; and four universal wheels 13 with braking function are provided at the bottom. The first side and the second side are opposite to each other, which makes it convenient for users to hold the handles 12 and move the calcining machine body 1 by means of the universal wheels 13. When pulling out the machine, the pulleys 11 can be used to make it convenient and easy to move.

[0031] Considering that users may find it difficult to pull out the calcining machine due to the smooth surface, making it hard to find a suitable point of force, and that excessive pulling may cause the pull-out cavity 5 to fall off, or that too much medicine in the calcining barrel 52 may cause the pull-out cavity 5 to tilt due to excessive weight, the following design is implemented: two narrow circular grooves 10 are provided on the bottom side of the calcining machine body 1; a heating device 4 is fixedly installed inside the calcining machine body 1; a limiting mechanism 500 is fixedly installed on the baffle 50 near the bottom side of the calcining machine body 1; and a roller 501 is fixedly installed at the center of the bottom of the baffle 50. A pull-out handle 502 is provided to facilitate the user's pulling action. The pull-out cavity 5 slides in the narrow circular groove 10 through the limiting mechanism 500. Because the end size of the limiting mechanism 500 is larger than the outlet size of the narrow circular groove 10, it can block the user's movement when pulling out, preventing the pull-out cavity 5 from falling. In addition, because a roller 501 is fixedly installed at the bottom center of the baffle 50 and the bottom of the roller 501 is flush with the ground, the roller 501 provides support when the user pulls outward.

[0032] Considering that stirring is required during the calcination process to ensure uniform heating of the medicinal materials, a stirring device 3 is fixedly installed on the second side of the calcination machine body 1. The stirring device 3 is connected to the stirring shaft 32 extending into the interior of the calcination machine body 1 by fixing screws 30 and fixing nuts 31. The stirring device 3 can uniformly stir the medicinal materials, ensuring uniform heating and preventing excessive heating at the bottom and insufficient heating at the top.

[0033] Considering that the stirring shaft 32 of the stirring device 3 needs to be inserted deep into the calcining machine body 1 to rotate, and that the stirring shaft 32 needs to be disassembled after calcination to remove the pull-out cavity 5, if the top of the calcining machine body 1 is closed, there will be no extra space for rotation and the stirring shaft 32 cannot be disassembled. Therefore, the top of the calcining machine body 1 cannot be closed. Thus, the following is feasible: two openable semi-circular covers 2 are embedded in the center of the top of the calcining machine body 1. The center of the two semi-circular covers 2 is provided with a semi-circular notch 20 for alignment and splicing. By setting the two semi-circular covers 2, the stirring shaft 32 can be disassembled. The semi-circular notch 20 provides the space required for the top of the stirring shaft 32 to rotate.

[0034] In summary, the working principle of this solution is as follows:

[0035] The user removes the two semi-circular covers 2 and adds medicinal materials to the calcination barrel 52. After adding the materials, the user closes the two semi-circular covers 2 to seal the calcination body 1. Once sealed, calcination can begin. After calcination, the user removes the two semi-circular covers 2 to provide space for removing the stirring shaft 32. Then, the user removes the fixing screws 30 and fixing nuts 31 to remove the stirring shaft 32. The user then cleans any remaining medicinal materials from the stirring shaft 32 and places them into the calcination barrel 52. After cleaning, the user can remove the pull-out cavity 5 and use the two handles to lift the calcination barrel 52 to pour out the medicinal materials. After the calcination barrel 52 is poured out, it is cleaned. After cleaning, the bottom protrusion 520 of the calcination barrel 52 is embedded into the concave groove 510 by using the two handles, so that the calcination barrel 52 is fixed inside the pull-out cavity 5. At the same time, the pull-out cavity 5 is pulled inward so that its baffle 50 is aligned with the second side of the calcination machine body. Then, the stirring shaft 32 and the stirring device 3 are installed. Finally, the two semi-circular covers 2 are put on. The pull-out and detachable device makes it convenient for users to operate the calcination machine and clean up the remaining medicinal materials, which provides convenience and increases the calcination effect.
