Description

Technical Field

[0001] The invention relates to the technical field of medicine steaming equipment, in particular to a rotary drum medicine steaming machine. Background Art

[0002] The steaming method in Chinese medicine preparation is to add specified auxiliary materials (wine, vinegar juice, etc.) to the cleaned or cut medicine, or put it into a certain steaming container (or steaming equipment) without adding auxiliary materials and heat it in water or with steam to a certain degree.

[0003] Its main purposes are: 1) to change the properties of drugs and expand the scope of drug use; by steaming, the medicinal properties and efficacy characteristics of some drugs are changed, so that the same drug has different properties and is used to treat different diseases, expanding the scope of use of the same drug. For example, raw rehmannia is cold in nature and has the effect of clearing heat and cooling blood. After steaming mature rehmannia, the medicinal properties change from cold to warm, and the effect changes from clearing to tonic; 2) to reduce adverse reactions; for example, raw rhubarb has a heavy smell and a strong laxative effect, which can easily damage the stomach qi; after steaming with wine, the laxative effect is weakened, which can relieve adverse reactions such as abdominal pain; raw polygonatum irritates the throat, Steaming can eliminate its adverse reactions; 3) Preserve the efficacy; It is conducive to storage. For example, mulberry silkworm cocoons contain a large number of active eggs, which will hatch and lose their efficacy under suitable conditions. Steaming can kill the eggs and facilitate storage; steaming astragalus can destroy the hydrolase coexisting with glycosides, which is conducive to preserving the effective ingredients of glycosides; 4) It is easy to slice; when medicinal materials such as papaya and gastrodia are softened, it is difficult for water to penetrate. Long soaking can easily reduce the content of their effective ingredients and easily cause rot. Softening by steaming can allow water vapor to directly penetrate the medicinal materials, improve the softening effect of the medicinal materials, and make them easy to cut and dry.

[0004] However, the prior art has the following defects: 1. Low efficiency of static steaming: Traditional steaming machines use a fixed steamer structure, and the stacking of medicinal materials leads to uneven steam penetration, which affects the extraction of medicinal effects; 2. Impact on medicinal efficacy: Steam directly contacts medicinal materials and reduces their efficacy. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art and to propose a rotary drum medicine steaming machine.

In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features.

[0021] In the description of the present invention, unless otherwise clearly defined and limited, the terms "mounted", "connected", and "coupled" shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] In the description of this specification, the descriptions with reference to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0023] Embodiment 1 Referring to Figure 1 - Figure 2 , a rotary drum type medicinal herb steaming machine, comprising: A box body 1, which is internally provided with a medicinal herb steaming chamber 3, and a box door 2 is arranged on one side; A rotatable bracket 4, driven by a frequency conversion motor 5, and a medicinal herb steaming container 6 is arranged inside it to achieve continuous tumbling of the medicinal herbs dynamically; A steam spray pipe 7, arranged at the bottom of the box body 1, for delivering steam into the box body 1 to steam the medicinal herbs; A steam recovery pipe 8, arranged at the top of the box body 1, for discharging steam.

[0024] When this device is in use, it is driven by the rotatable bracket 4 and the variable-frequency motor 5, so that the medicinal materials continuously tumble during the steaming process, achieving dynamic heating. The dynamic tumbling increases the heating area of the medicinal materials, avoiding adhesion into lumps. The medicinal materials are heated more evenly during steaming. At the same time, the steam wraps the steaming container 6 from bottom to top, and heats the medicinal materials through the heat conduction of the steaming container 6, avoiding direct contact between the steam and the medicinal materials and reducing the medicinal effect.

[0025] In this embodiment, the steaming container 6 is integrally formed of ceramic material, and the ceramic material has the following effects: Naturally resistant to acid and alkali corrosion, avoiding possible oxidation pollution of metal containers or chemical substance migration of plastic containers; Does not react with the active ingredients of the medicinal materials, ensuring pure medicinal properties without loss during the steaming process; The low thermal conductivity characteristic of the ceramic forms a uniform thermal field and prevents the medicinal materials from carbonizing due to local overheating; The heat storage characteristic of the ceramic reduces the frequency of repeated heating of the steam and maintains the stability of the thermal field; And in cooperation with the rotatable bracket 4, the following can be achieved: The rotatable bracket 4 continuously tumbles the medicinal materials. In cooperation with the temperature control characteristic of the ceramic, the heat gradient difference when the steam penetrates the medicinal materials is eliminated; The medicinal materials are heated more evenly inside and outside, avoiding incomplete processing or component damage caused by uneven local heating; The rotation action greatly shortens the contact time between the medicinal materials and the inner wall of the container, forming an intermittent contact heating mode, which is especially suitable for the fine processing of easily gelatinized and adhered medicinal materials and precious medicinal materials.

[0026] In this embodiment, a supporting wheel assembly 9 is installed at the bottom of the steaming chamber 3. The supporting wheel assembly 9 forms a support for the bottom of the rotatable bracket 4, and the rolling support reduces the friction resistance of the rotatable bracket 4 and prevents the bracket from deforming during large-load rotation.

[0027] In this embodiment, the rotatable bracket 4 includes annular brackets 10 on both sides and an intermediate limit frame 11 connecting the two annular brackets 10. One side of the intermediate limit frame 11 is designed with an opening, and a limit frame door 12 for closing the opening is detachably installed at the opening. The inner cavity size of the limit frame is adapted to a plurality of steaming containers 6. The opening design facilitates the loading and unloading of the steaming containers 6. The limit frame ensures that the plurality of containers maintain a fixed position during rotation. The limit frame door 12 is connected to the annular bracket 10 on one side by bolts and abuts against the steaming container 6 located on the side to achieve the positioning of the steaming container 6. When loading the medicine, take out the steaming container 6, open the cover body of the steaming container 6 (not shown in the figure) and put the medicinal materials in.

[0028] In this embodiment, a motor installation chamber 13 is further provided inside the box body 1. The motor installation chamber 13 is located on one side of the medicine steaming chamber 3. The variable-frequency motor 5 is installed at the bottom of the motor installation chamber 13. A transmission member 14 is rotatably installed on the wall surface between the motor installation chamber 13 and the medicine steaming chamber 3 through a sealed bearing. Transmission wheels 15 are installed at the driving end of the variable-frequency motor 5 and at one end of the transmission member 14 located inside the motor installation chamber 13. The two transmission wheels 15 are connected by a transmission belt 16. The transmission member 14 is connected to the annular bracket 10 through a flange and bolts. In this way, the variable-frequency motor 5 can drive the corresponding transmission wheel 15 to rotate, thereby driving another transmission belt 16, the transmission member 14, and the rotatable bracket 4 to rotate through the transmission belt 16.

[0029] Embodiment 2 As Figure 3 - Figure 7 shown, the difference between this embodiment and Embodiment 1 is that: In this embodiment, a positioning member 17 is provided on one side of the transmission member 14 located inside the medicine steaming chamber 3. The transmission member 14 is cylindrical. Both the positioning member 17 and the positioning groove 18 are diamond-shaped. A positioning groove 18 adapted to the positioning member 17 is provided on one side of the annular bracket 10. When the transmission member 14 rotates, the annular bracket 10 is driven to rotate through the positioning member 17 and the positioning groove 18. The positioning member 17 and the annular bracket 10 are in limit transmission through the positioning groove 18. On the one hand, the isolation of the motor installation chamber 13 and the medicine steaming chamber 3 can isolate the variable-frequency motor 5 from the steam environment, and the positioning component eliminates rotational slippage. The positioning groove 18 and the positioning member 17 can be fixed by bolts or welding during initial installation to complete the assembly of the positioning groove 18 and the positioning member 17. Of course, if there is a need to frequently remove the rotatable bracket 4, the positioning groove 18 and the positioning member 17 can form a transmission process only by inserting the positioning member 17 into the positioning groove 18. Of course, this process requires that when the box door 2 is closed, a restriction is formed on the side of the rotatable bracket 4 away from the positioning member 17 to prevent the rotatable bracket 4 from forming a horizontal displacement during rotation. This is different from Embodiment 1. Embodiment 1 is a rigid connection, while this embodiment adopts a structural design that is convenient for disassembly.

[0030] In this embodiment, rotating seats 19 are rotatably installed on both sides of the medicine steaming container 6 and on the inner side of the limit frame door 12 through sealed bearings. Symmetrically arranged positioning rod assemblies 20 and symmetrically arranged positioning hole assemblies 22 are provided on the surface of the rotating seat 19. The positioning rod assemblies 20 are adapted to the positioning hole assemblies 22. The rotating seats 19 with positioning rod assemblies 20 and positioning hole assemblies 22 are provided on both sides of the medicine steaming container 6, and the rotating seats 19 are synchronously configured on the inner side of the limit frame door 12, so that the medicine steaming containers 6 can be quickly stacked and locked through the positioning rod assemblies 20 and the positioning hole assemblies 22.

[0031] In this embodiment, a push rod motor 26 is installed on one side of the interior of the motor installation chamber 13 away from the medicine steaming chamber 3. A push rod 25 is installed at the driving end of the push rod motor 26. The push rod 25 horizontally and movably penetrates through the transmission wheel 15, the transmission member 14, the positioning member 17, and the positioning groove 18 in sequence. And a second positioning rod assembly 21 is installed at one end of the push rod 25 away from the push rod motor 26. The second positioning rod assembly 21 is adapted to the positioning hole assembly 22. In the medicine steaming container 6, the inner sides of the two rotating seats 19 both extend to the inner side of the medicine steaming container 6, and a stirring member 23 is installed between the two rotating seats 19. When the push rod motor 26 drives the push rod 25 to penetrate through the transmission member 14, the second positioning rod assembly 21 can be locked with the positioning hole assembly 22 on the medicine steaming container 6. The transmission member 14 can normally drive the medicine steaming container 6 to rotate. Under the action of the corresponding second positioning rod assembly 21, the rotating seat 19 remains stationary but has relative movement with the medicine steaming container 6, which can break up the lumps of medicinal materials. Of course, in this embodiment, the material of the medicine steaming container 6 is different from that in Embodiment 1. In this embodiment, a metal material can be used, such as metal titanium, iron, etc. Because in the ceramic material, the cost of installing the stirring member 23 is relatively high. Therefore, in Embodiment 1, the stirring member 23 is not provided. In the medicine steaming container 6 made of this metal material, the stirring member 23 is added.

[0032] In this embodiment, a plurality of medicine steaming chambers 3 are provided, and a plurality of steam recovery pipes 8 are provided, corresponding to the plurality of medicine steaming chambers 3 one by one. And the outer end of the steam recovery pipe 8 is connected to a heat exchanger 24, which supports synchronous steaming of different medicinal materials in separate chambers; the recovered waste heat of the steam is converted into hot water for recycling through the heat exchanger 24, realizing cascaded utilization of energy.

[0033] In this embodiment, a filling pad is provided on the contact surface between the medicine steaming container 6 and the rotatable bracket 4, and the material of the filling pad is polyurethane foam, which can buffer the impact of rotational vibration on the container and reduce the noise of metal collision.

[0034] In this embodiment, the supporting wheel assembly 9 includes two supporting wheels rotatably installed at the bottom of the medicine steaming chamber 3, and the two supporting wheels are respectively located on both sides of the bottom of the annular bracket 10, forming a stable triangular supporting surface to disperse the rotational load of the bracket.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
