[0002] Medicinal powder is obtained by crushing medicinal materials, and can be used to prepare drugs in dosage forms such as granules, tablets, capsules, and powders. For example, Mongolian medicine powder is obtained by crushing Mongolian medicine. Mongolian medicine is similar to traditional Chinese medicine, mainly herbal medicine, and is made by grinding a variety of herbs into medicinal powder. Specifically, in the preparation process of Mongolian medicine, each herb is first crushed, and then the crushed Mongolian medicine powder is mixed in a certain proportion. After that, according to the type of medicine, the mixed Mongolian medicine powder is screened, dried, granulated or tableted, and finally tested and packaged to obtain the finished Mongolian medicine. In other words, the preparation process of Mongolian medicine requires the use of a powder mixing device.

[0003] The existing medicine powder mixing device adds various Mongolian medicine powders used to prepare Mongolian medicine into a mixing tank according to a certain proportion, and then mixes the various Mongolian medicine powders entering the mixing tank through a stirring paddle in the mixing tank. After the mixing process is completed, a certain amount of Mongolian medicine powder will adhere to the stirring paddle, resulting in poor accuracy in the ratio of the Mongolian medicine powder obtained after mixing, and causing waste of Mongolian medicine powder.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0025] refer to Figures 1 to 3 The present application provides a medicine powder mixing device, comprising:

[0026] A mixing box 100 , the top of which is connected to a feeding pipe 101 ; wherein the feeding pipe 101 is used to add various Mongolian medicine powders for preparing Mongolian medicine into the mixing box 100 .

[0027] The mixing component 200 is arranged on the mixing box 100, and is used for mixing the medicinal powder entering the mixing box 100 from the feeding pipe 101; wherein, the mixing box 100 is provided with a discharge port, and the various Mongolian medicine powders for preparing Mongolian medicine in the mixing box 100 are mixed by the mixing component 200 to obtain a uniformly mixed Mongolian medicine powder, and the uniformly mixed Mongolian medicine powder is discharged to the outside of the mixing box 100 through the discharge port on the mixing box 100 and collected.

[0028] The jet pipe 300 is used to introduce compressed gas into the mixing box 100. One end of the jet pipe 300 penetrates the side wall of the upper section of the mixing box 100 and extends into the mixing box 100. A branch pipe 301 is vertically connected downwardly on the jet pipe 300 near the outer wall of the mixing box 100. The jet pipe 300 located in the mixing box 100 is connected with a plurality of first jet nozzles 400. The branch pipe 301 is connected with the mixing box 100 through a plurality of second jet nozzles 401 (the jet ports of the second jet nozzles 401 penetrate and extend into the mixing box 100). The compressed gas may be an inert gas, air, etc. The multiple first air nozzles 400 on the air injection pipe 300 blow air vertically downward into the mixing box 100, while the multiple second air nozzles 401 on the branch pipe 301 blow air horizontally into the mixing box 100, so that the mixing component 200 can be purged by compressed gas from the vertical and horizontal directions during the rotation of the mixing component 200, thereby effectively blowing the Mongolian medicine powder attached to the mixing component 200 to the inner bottom of the mixing box 100, thereby improving the purging efficiency of the Mongolian medicine powder attached to the mixing component 200. In addition, please refer to Figure 2, the horizontal distance between one end of the jet pipe 300 located in the mixing box 100 and the feeding pipe 101 is a preset distance (which can be set according to actual needs, so the present application does not specifically limit it here), so that the Mongolian medicine powder falling from the feeding pipe 101 will not fall on the jet pipe 300. And the part of the mixing assembly 200 in the mixing box 100 for mixing the Mongolian medicine powder therein is below the jet pipe 300 in the mixing box 100, and the mixing box 100 is provided with a visual observation window 104, through which the height of the Mongolian medicine powder added to the mixing box 100 is less than or equal to the height of the mixing assembly 200 in the mixing box 100 for mixing the Mongolian medicine powder therein, that is, the maximum height of the Mongolian medicine powder added to the mixing box 100 is less than the height of the jet pipe 300, so that the Mongolian medicine powder will not adhere to the jet pipe 300 during the mixing assembly 200 in the mixing box 100 stirring the Mongolian medicine powder therein.

[0029] The powder mixing device provided in the present application mixes various Mongolian medicine powders added into the mixing box 100 from the feed pipe 101 through the mixing component 200, and after the mixing process is completed (meaning that the evenly mixed Mongolian medicine powder is discharged to the outside of the mixing box 100 and collected), Mongolian medicine powder is attached to the mixing component 200, and compressed gas is introduced into the mixing box 100 through the jet pipe 300, and the jet pipe 300 is located in the mixing box 100. The tube body of the jet pipe 300 is located in the upper section of the mixing box 100 and is vertically connected to a branch pipe 301 near the inner wall of the mixing box 100, and the compressed gas entering the jet pipe 300 is vertically downward into the mixing box 100 through a plurality of first jet nozzles 400 thereon. Compressed gas is sprayed, and the compressed gas entering the branch pipe 301 is blown horizontally into the mixing box 100 through the multiple second air nozzles 401 thereon, and during the air jetting process, the mixing component 200 is opened to put it in a working state for mixing the medicine powder (i.e., a rotating state), so that the compressed gas sprayed from the first air nozzle 400 on the air jet pipe 300 and the second air nozzle 401 on the branch pipe 301 blows the Mongolian medicine powder attached to the mixing component 200 to the inner bottom of the mixing box 100, and discharges it to the outside of the mixing box 100 to be collected together with the Mongolian medicine powder obtained by mixing in the previous step, thereby avoiding the waste of Mongolian medicine powder and improving the accuracy of the ratio of the Mongolian medicine powder obtained after mixing.

[0030] In some embodiments, reference Figure 2 The feed pipe 101 in the present application is connected to the middle part of the top of the mixing box 100, and the length of the tube body of the air jet pipe 300 located in the mixing box 100 is less than half the length of the mixing box 100; this prevents the Mongolian medicine powder entering the mixing box 100 from the feed pipe 101 from falling on the air jet pipe 300 and affecting the accuracy of the Mongolian medicine powder ratio, so that all kinds of Mongolian medicine powder entering the mixing box 100 can be mixed by the mixing assembly 200 to obtain evenly mixed Mongolian medicine powder.

[0031] The air outlets of the multiple first air nozzles 400 connected on the tube body of the air jet pipe 300 located in the mixing box 100 are all directed vertically downward, and the air outlets of the multiple second air nozzles 401 connected on the branch pipe 301 are all inclined downward. In this way, during the mixing process of the mixing component 200 (i.e., the rotation of the mixing component 200 in the mixing box 100), the compressed gas ejected from the multiple first air nozzles 400 on the air jet pipe 300 and the compressed gas ejected from the multiple second air nozzles 401 on the branch pipe 301 both blow the Mongolian medicine powder attached to the mixing component 200 toward the inner bottom of the mixing box 100, so that the Mongolian medicine powder attached to the mixing component 200 can quickly fall off it, thereby improving the purging efficiency of the Mongolian medicine powder attached to the mixing component 200.

[0032] In some embodiments, reference Figure 1 The top of the feed pipe 101 in the present application is connected to a storage hopper 1011, and the feed pipe 101 is provided with an electrically connected rotary feed valve 1013 and a powder flow meter 1012 from top to bottom. The specifications and models of the powder flow meter 1012 and the rotary feed valve 1013 can be purchased according to actual needs, and therefore, the present application does not specifically limit them. In addition, the rotary feed valve 1013 is close to the discharge port of the storage hopper 1011, so that after the rotary feed valve 1013 is closed, the Mongolian medicine powder in the storage hopper 1011 no longer falls.

[0033] In the above embodiment, Mongolian medicine powder for preparing Mongolian medicine is added into the storage hopper 1011. Since the amount of each Mongolian medicine powder required for preparing Mongolian medicine is determined (in order to ensure the accuracy of each Mongolian medicine powder added into the mixing box 100 through the storage hopper 1011, after one Mongolian medicine powder is added into the storage hopper 1011, the storage hopper 1011 is replaced and another Mongolian medicine powder is added into the mixing box 100 through the replaced storage hopper 1011), the rotary feeding valve 1013 is opened to feed the quantitative Mongolian medicine powder into the mixing box 100. Mongolian medicine powder is added through the feed pipe 101, and the amount of each Mongolian medicine powder is accurately measured by the powder flow meter 1012. After measuring the determined amount of Mongolian medicine powder, the powder flow meter 1012 gives an electrical signal to the rotary feeding valve 1013 electrically connected to it, and the rotary feeding valve 1013 is closed. The Mongolian medicine powder measured by the powder flow meter 1012 flows into the mixing box 100 through the feed pipe 101 below it, thereby achieving accurate quantification of Mongolian medicine powder, thereby improving the accuracy of the Mongolian medicine preparation process.

[0034] In some embodiments, reference Figure 2The mixing assembly 200 in the present application includes a rotating shaft 201 and a plurality of mixing plates 202; specifically, the top end of the rotating shaft 201 vertically penetrates the bottom of the mixing box 100 and extends into the mixing box 100, and the plurality of mixing plates 202 are vertically arranged at equal intervals on the shaft body of the rotating shaft 201 located in the mixing box 100, and the bottom end of the rotating shaft 201 is driven by a driving motor 500. The shaft body of the rotating shaft 201 is rotatably connected to the bottom of the mixing box 100 through a sealed bearing.

[0035] In the above embodiment, the driving motor 500 is turned on, and the rotating shaft 201 is driven to rotate by the driving motor 500. During the rotation, the rotating shaft 201 drives the multiple mixing plates 202 thereon to rotate accordingly. During the rotation, the multiple mixing plates 202 mix the various Mongolian medicine powders in the mixing box 100 to obtain uniformly mixed Mongolian medicine powders.

[0036] In some embodiments, reference Figure 1 The bottom of the mixing box 100 in the present application is provided with a support frame 102, on which a bearing plate 1021 for placing the driving motor 500 is provided, and the output shaft of the driving motor 500 is connected to the bottom end of the rotating shaft 201. The driving motor 500 is supported by the bearing plate 1021, so that the stability of the driving motor 500 is achieved, so that the mixing component 200 has a higher stability in the mixing process of various Mongolian medicine powders in the mixing box 100.

[0037] In some embodiments, reference Figure 1 and Figure 3 The bottom of the mixing box 100 in the present application is connected to a first discharge pipe 103, a rotary discharge valve 1031 is provided on the discharge pipe 103, the bottom end of the discharge pipe 103 is connected to a horizontal buffer bin 600, a screw conveyor 601 is provided in the horizontal buffer bin 600, and one end of the horizontal buffer bin 600 away from the discharge pipe 103 is connected to a second discharge pipe 602, and a draft fan 6021 is provided on the second discharge pipe. The specifications and models of the rotary discharge valve 1031 can be selected according to actual needs, so the present application does not specifically limit it.

[0038] In the above embodiment, after the mixing process is completed, the rotary unloading valve 1031 and the induced draft fan 6021 are opened, and under the suction of the induced draft fan 6021, the evenly mixed Mongolian medicine powder in the mixing box 100 enters the horizontal buffer bin 600 through the discharge pipe 103, and then is output through the screw conveyor 601 in the horizontal buffer bin 600. On the one hand, the screw conveyor 601 improves the output efficiency of the Mongolian medicine powder in the horizontal buffer bin 600, and on the other hand, it allows the Mongolian medicine powder to be further mixed in the horizontal buffer bin 600, thereby improving the mixing efficiency of the Mongolian medicine powder.

[0039] In some embodiments, reference Figure 1 In the present application, a gas compressor 302 is arranged at one end of the jet pipe 300 located outside the mixing box 100. The gas compressor 302 is a power device that converts mechanical energy into gas pressure energy, and is commonly used for pneumatic tools to provide gas power. In the present application, the gas enters the gas compressor 302 through the air inlet of the gas compressor 302, and after being compressed by the gas compressor 302, a compressed gas with a certain pressure (so that it has a purging power) is obtained, and the compressed gas enters the jet pipe 300 through the air outlet of the gas compressor 302, and then is ejected through the multiple jet nozzles 400 on the jet pipe 300 and the multiple jet nozzles 400 on the branch pipe 301 in sequence, and blows off the Mongolian medicine powder attached to the mixing assembly 200, thereby improving the purging efficiency of the Mongolian medicine powder.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
