Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material processing, and particularly relates to a medicinal material pulverizer for preventing overheating, ignition and caking. Background Art

[0002] In the process of traditional Chinese medicine processing, a medicinal material pulverizer is needed to grind traditional Chinese medicine raw materials into fine powder for subsequent use in the pharmaceutical process, so that the effective components of the medicinal materials can be fully released, and the bioavailability and curative effect of the medicine can be improved.

[0003] After retrieval, a patent with the Chinese patent application number 202321289897.5 discloses a traditional Chinese medicine pulverizer, belonging to the technical field of pulverizers. A traditional Chinese medicine pulverizer includes a pulverizing box, and a grinding member is arranged inside the pulverizing box. The grinding member includes a grinding seat installed and connected to the inner wall of the pulverizing box. A rotatable grinding column is arranged inside the grinding seat. A first scraper is installed on the surface of the grinding column. The first scraper contacts the inner wall of the grinding seat. A second scraper is arranged at the gap between the inner wall of the grinding seat and the surface of the grinding column. The second scraper contacts the first scraper; in the utility model, the first scraper effectively cleans the residual powder of traditional Chinese medicine attached to the inner wall of the grinding seat, the second scraper cleans the residual powder of traditional Chinese medicine on the surface of the grinding column, and the third scraper effectively cleans the inner bottom wall of the grinding seat, so as to effectively remove the ground traditional Chinese medicine powder;

[0004] The above patent still has the following deficiencies: (1) The medicinal material powder is prone to catching fire or caking when heated. During the pulverizing process of the medicinal materials, due to the friction of grinding tools such as grinding discs, grinding wheels and cutters, a large amount of heat will be generated. If these heats cannot be effectively dissipated, they will accumulate in the medicinal material powder, easily causing scorching, ignition or caking, resulting in a reduction in the medicinal effect and affecting the normal use of the medicinal materials;

[0005] (2) The medicinal materials are not easy to fall. Since the dried traditional Chinese medicine materials are hard in texture and irregular in shape, directly putting them into the hopper easily causes the medicinal materials to get stuck inside the connecting pipe and not fall easily, affecting the normal use of the device.

[0006] Therefore, there is an urgent need for a medicinal material pulverizer for preventing overheating, ignition and caking to solve the above problems. Summary of the Utility Model

[0037] As Figures 1-5 shown, the medicinal material crusher for preventing overheating, ignition and agglomeration proposed in this embodiment includes a support frame 1, and also includes,

[0038] A powder cylinder 2, fixed on one side of the top end of the support frame 1, and a rotating shaft 14 is rotatably connected inside the powder cylinder 2. A crushing wheel 11 is fixed on one side of the rotating shaft 14, and a second driving wheel 16 is sleeved outside the rotating shaft 14;

[0039] A filter screen 3, fixed inside the bottom end of the powder cylinder 2, and a discharge port 4 is installed at the bottom end of the powder cylinder 2;

[0040] A temperature reduction structure 8, arranged outside the powder cylinder 2. Among them, the temperature reduction structure 8 includes a composite heat preservation shell 801 sleeved outside the powder cylinder 2, a shunt pipe 802 installed on one side of the composite heat preservation shell 801, a return pipe 803 installed on the other side of the composite heat preservation shell 801, and a heat conduction component arranged inside the composite heat preservation shell 801;

[0041] The cover plate 6 is rotatably connected to one side of the cooling structure 8, and crushing teeth 5 are fixed to one side of the cover plate 6. A connecting pipe 7 is installed on the other side of the cover plate 6, and a fixing buckle 12 is installed on one side of the cooling structure 8.

[0042] The hopper 10 is fixed to the top of the cooling structure 8, and a crushing structure 9 is arranged inside the hopper 10.

[0043] The driving motor 15 is installed on one side inside the support frame 1, and a first driving wheel 13 is installed at the rotating end of the driving motor 15.

[0044] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, the heat conduction component includes a connecting copper plate 804 embedded on the outer side of the powder cylinder 2 and heat conduction columns 805 fixed on the outer side of the connecting copper plate 804. There are several groups of heat conduction columns 805 arranged on the outer side of the connecting copper plate 804, and several groups of heat conduction columns 805 are evenly distributed on the outer side of the connecting copper plate 804. The shunt pipe 802 is connected to the return pipe 803 through the composite heat preservation shell 801. The connecting copper plate 804 is made of copper material. Connect the cooling pipeline to the shunt pipe 802, introduce cold water into the shunt pipe 802, so that the shunt pipe 802 shunts the cold water and injects it into the composite heat preservation shell 801, so that the cold water flows in the cavity inside the composite heat preservation shell 801. The thickness of the powder cylinder 2 is reduced through the connecting copper plate 804, so as to facilitate the heat conduction from the inside of the powder cylinder 2. At the same time, the heat conduction columns 805 increase the contact area between the connecting copper plate 804 and the cold water, accelerating the heat dissipation. The hot water inside the composite heat preservation shell 801 is led out through the return pipe 803 for recycling.

[0045] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, as a preferred embodiment, on the basis of the above method, further comprising a first crushing roller 904 installed on one side inside the hopper 10, a first transmission gear 903 fixed to one side of the second crushing roller 905, a third transmission wheel 901 installed on one side of the first transmission gear 903, a second transmission gear 906 meshing with one side of the first transmission gear 903, a second crushing roller 905 fixed to one side of the second transmission gear 906, and a fourth transmission wheel 902 installed outside the rotating shaft 14. The power of the rotating shaft 14 is transmitted to the third transmission wheel 901 through the fourth transmission wheel 902 via a transmission belt, causing the third transmission wheel 901 to rotate the first crushing roller 904 and the first transmission gear 903 counterclockwise. Immediately afterwards, the first transmission gear 903 drives the second transmission gear 906 to rotate clockwise through the engagement of the teeth, causing the second crushing roller 905 to rotate clockwise. When the medicinal materials fall between the second crushing roller 905 and the first crushing roller 904, the second crushing roller 905 and the first crushing roller 904 crush the medicinal materials, preliminarily crushing the medicinal materials and reducing the volume of the medicinal materials.

[0046] Specifically, when the medicinal material pulverizer for preventing overheating, ignition and caking is in use: Pour the medicinal materials into the hopper 10, start the drive motor 15 to rotate, so that the drive motor 15 drives the rotating shaft 14 to rotate through the first transmission wheel 13 and the second transmission wheel 16. At the same time, the crushing structure 9 operates to preliminarily crush the medicinal materials in the hopper 10, reducing the volume of the medicinal materials and facilitating the falling of the medicinal materials. The medicinal materials enter the inside of the powder cylinder 2 through the connecting pipe 7. The rotating shaft 14 drives the crushing wheel 11 to rotate at high speed, so that the crushing wheel 11 and the crushing teeth 5 crush the medicinal materials. The medicinal materials are filtered through the filter screen 3. The qualified medicinal material powder passes through the filter screen 3 and is discharged from the discharge port 4. By removing the fixing buckle 12 and pushing the cover plate 6 to flip to one side, the powder cylinder 2 is opened to facilitate the cleaning of the inside of the powder cylinder 2. The inside of the powder cylinder 2 is cooled by the cooling structure 8.

[0047] Connect the cooling pipeline to the shunt pipe 802, introduce cold water into the shunt pipe 802, so that the shunt pipe 802 shunts the cold water and injects it into the composite heat-insulating shell 801, so that the cold water flows in the cavity inside the composite heat-insulating shell 801. The thickness of the powder cylinder 2 is reduced through the connecting copper plate 804 to facilitate the conduction of the heat inside the powder cylinder 2. At the same time, the heat-conducting column 805 increases the contact area between the connecting copper plate 804 and the cold water, accelerating the dissipation of heat. The hot water inside the composite heat-insulating shell 801 is led out through the return pipe 803 for recycling;

[0048] The power of the rotating shaft 14 is transmitted to the third driving wheel 901 through the fourth driving wheel 902 via a transmission belt, causing the third driving wheel 901 to rotate, and the first crushing roller 904 and the first driving gear 903 to rotate counterclockwise. Immediately afterwards, the first driving gear 903 drives the second driving gear 906 to rotate clockwise through the engagement of the teeth, causing the second crushing roller 905 to rotate clockwise. When the medicinal materials fall between the second crushing roller 905 and the first crushing roller 904, the second crushing roller 905 and the first crushing roller 904 crush the medicinal materials, initially crushing the medicinal materials and reducing the volume of the medicinal materials.
