A spray device for total oil mixture of Chinese herbal medicine granules

Abstract

This application relates to the technical field of granular material mixing equipment, and discloses a spray device for mixing Chinese herbal medicine granules with oil. The device includes a fixed frame, with a hollow drive shaft movably sleeved inside the frame. The right end of the drive shaft is fixedly connected to a drive motor fixedly installed on the top right side of the fixed frame. An inner shell is fixedly sleeved on the middle of the outer surface of the drive shaft, and an end cap is movably sleeved on the left side of the outer surface of the drive shaft, with its end face fixedly connected to the left side of the outer surface of the inner shell. The spray device for mixing Chinese herbal medicine granules with oil provided in this application allows for the atomization of fragrance delivered from a pressure tank via compressed air. This fragrance is then mixed with the Chinese herbal medicine granules "tumbling" within the inner shell, ensuring sufficient contact between the granules and the atomized fragrance. Furthermore, the atomized fragrance, due to its small particle size, does not adhere to the surface of the Chinese herbal medicine granules, preventing clumping.

Description

Technical Field

[0001] This application relates to the field of granular material mixing equipment, and in particular to a spray device for mixing Chinese medicine granules with oil. Background Technology

[0002] A mixer is a mechanical device that uses mechanical force and gravity to uniformly mix two or more materials. Because it can effectively increase the contact surface area between materials, promote chemical reactions between materials, and accelerate physical changes between materials, it is widely used in medical, chemical and other fields.

[0003] In the production and processing of traditional Chinese medicine (TCM), to mask the odor and improve the taste, it is often necessary to uniformly add flavorings (such as sweet orange oil) to the TCM granules using a mixer. However, existing mixers only have a good mixing effect on two or more granular materials. The flavorings added to TCM granules are mostly liquid oils. Because liquid oils have high viscosity, they are difficult to flow between TCM granules. As a result, existing mixers have poor mixing uniformity between TCM granules and flavorings, and the mixing efficiency is relatively low. In addition, liquid oil flavorings are prone to clumping during the stirring process because they adhere to the surface of TCM granules, resulting in poor stability and reliability.

[0004] Therefore, there is an urgent need for a mixing device for Chinese medicine granules and spices to solve the defects of the existing mixers when mixing Chinese medicine granules and liquid oils and spices. Summary of the Invention

[0005] This application proposes a spray device for mixing Chinese herbal medicine granules with oil, which has the advantages of atomizing liquid oily fragrance with nozzles before mixing with Chinese herbal medicine granules, resulting in better uniformity and higher efficiency of mixing. At the same time, it avoids the clumping of liquid oily fragrance due to the adhesion of Chinese herbal medicine granules to the surface. This solves the problems of poor uniformity of mixing between Chinese herbal medicine granules and fragrance in existing mixers, low mixing efficiency, and easy clumping of liquid oily fragrance due to the adhesion of Chinese herbal medicine granules to the surface during the stirring process.

[0006] To achieve the above objectives, this application adopts the following technical solution: a spraying device for total oil mixture of traditional Chinese medicine granules, comprising a fixed frame, a hollow transmission shaft movably sleeved inside the fixed frame, and the right end of the transmission shaft being fixedly connected to a drive motor fixedly installed on the top right side of the fixed frame; an inner shell being fixedly sleeved in the middle of the outer surface of the transmission shaft, and an end cap movably sleeved on the left side of the outer surface of the transmission shaft and fixedly connected to the left side of the outer surface of the inner shell; a nozzle extending into the inner cavity of the inner shell is fixedly installed inside the end cap, and is connected to a pressure storage tank fixedly installed on the left side of the outside of the fixed frame through the hollow structure of the transmission shaft.

[0007] Furthermore, the outer surface of the drive shaft is movably sleeved with an outer shell that encloses the inner shell. The top of the right side of the fixing frame is provided with a planetary gear set that forms a transmission connection with the drive motor. The top of the outer surface of the inner shell is provided with a through groove that communicates with its inner cavity for the flow of Chinese medicine granules temporarily stored at the top of the inner cavity of the outer shell.

[0008] Furthermore, the inner wall of the outer shell is designed as a concave curved surface with the same curvature as the outer surface of the inner shell, so that the inner shell and the outer shell fit together tightly and divide the inner cavity of the outer shell into two sealed chambers, upper and lower.

[0009] Furthermore, the inner wall of the inner shell is provided with helical ribs arranged along the rotation direction of the inner shell, and the number of ribs is arranged in a ring array according to the inner diameter of the inner shell.

[0010] Furthermore, the speed at which the Chinese medicine granules stored in the upper chamber of the outer shell flow into the inner shell is directly proportional to the speed at which the outer shell rotates under the transmission action of the planetary gear set, and before the outer shell rotates to a 45° angle, the spices stored in its upper chamber can completely flow into the inner cavity of the inner shell.

[0011] Furthermore, the drive shaft is connected to the pressure tank via a flexible hose, with one end of the hose connected to the bottom of the pressure tank.

[0012] Furthermore, in the initial state, the nozzle is located above the center of the inner shell, which effectively prevents the herbal particles that enter the inner cavity of the inner shell through the channel from clogging the nozzle during the feeding process.

[0013] This invention application has the following technical effects:

[0014] 1. The herbal granule-oil mixture spraying device provided in this application, with the nozzle on the inner shell, can atomize the fragrance delivered by compressed air from the pressure storage tank, and then mix it with the herbal granules "tumbling" in the inner shell. This allows the herbal granules in the inner shell to fully contact the atomized fragrance, resulting in a good mixing effect. At the same time, because the atomized fragrance has a small particle size, it will not adhere to the herbal granules on its surface and cause clumping. As a result, the device has a high degree of uniformity in mixing between herbal granules and fragrance, with both good effect and high efficiency.

[0015] 2. The herbal granule total oil spraying device provided in this application, with the linkage structure between the inner shell and the outer shell, divides a large portion of the herbal granules in the outer shell into several smaller portions, and allows them to contact and mix with the atomized fragrance in the inner shell, further improving the uniformity of the mixing between the herbal granules and the fragrance. During the continuous rotation of the outer shell, the position between the upper and lower chambers is reversed, allowing the granules to flow back into the inner shell, or to be mixed again with atomized fragrance, or to be directly "tumbled" and stirred between the herbal granules, further improving the mixing effect between the herbal granules and the fragrance.

[0016] 3. The herbal granule total oil spraying device provided in this application has a rotation angle of the outer shell and a flow rate of herbal granules, which allows the fragrance stored in the upper chamber to flow completely into the inner cavity of the inner shell. After mixing with the atomized fragrance, the fragrance can fall entirely into the lower cavity of the outer shell, which facilitates feeding or discharging. Furthermore, no leftover herbal granules remain in the inner cavity of the outer shell, resulting in high stability and reliability of the device during operation. Attached Figure Description

[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] like Figure 1 As shown, a spraying device for a total oil mixture of traditional Chinese medicine granules includes a fixed frame 1 that can be fixedly installed on a workbench. A hollow drive shaft 2 is movably sleeved inside the fixed frame 1. The right end of the drive shaft 2 is fixedly connected to a drive motor 5 fixedly installed on the top right side of the fixed frame 1, and can rotate with the drive shaft of the drive motor 5. An inner shell 3 is fixedly sleeved on the middle of the outer surface of the drive shaft 2, and an end cap 4 is movably sleeved on the left side of the outer surface of the drive shaft 2, with its end face fixedly connected to the left side of the outer surface of the inner shell 3. Figure 3 As shown, a nozzle 6 is fixedly installed inside the end cap 4, extending into the inner cavity of the inner shell 3. It is connected to a pressure tank 9 for storing spices, which is fixedly installed on the left side of the fixed frame 1 via a flexible hose through the hollow structure of the drive shaft 2. Clean compressed air can be introduced into the pressure tank 9 to squeeze and deliver the spices stored therein to the nozzle 6. Under the action of the nozzle 6, the spices are atomized and mixed with the Chinese medicine particles in the inner shell 3. This allows the Chinese medicine particles "tumbling" in the inner shell 3 to come into full contact with the atomized spices, resulting in a high mixing effect. At the same time, the atomized spices will not clump due to the adhesion of Chinese medicine particles on the surface.

[0027] like Figure 2 As shown, in this technical solution, an outer shell 7, which encloses the inner shell 3, is movably sleeved on the outer surface of the drive shaft 2. An inlet and an outlet, respectively, are provided at the upper and lower ends of the outer shell 7, connecting to its inner cavity. A planetary gear set 8 is located on the top right side of the fixing frame 1, forming a transmission connection with the drive motor 5. When the inner shell 3 rotates at a high speed with the drive motor 5, the outer shell 7 can rotate at a lower speed under the transmission action of the planetary gear set 8. Figure 4 As shown, the top of the outer surface of the inner shell 3 is provided with a through groove 11 that connects to its inner cavity, which can be used to circulate the Chinese medicine particles temporarily stored in the top of the inner cavity of the outer shell 7, so that they can enter the inner cavity of the inner shell 3 and mix with the atomized fragrance sprayed by the nozzle 6.

[0028] like Figure 4 As shown, in this technical solution, the inner wall of the outer shell 7 is designed as a concave curved surface 12 with the same curvature as the outer surface of the inner shell 3, so that the inner shell 3 and the outer shell 7 fit together tightly, dividing the inner cavity of the outer shell 7 into two sealed chambers: upper and lower.

[0029] When the through groove 11 on the inner shell 3 rotates to the upper position, the Chinese medicine granules stored in the upper chamber of the outer shell 7 can quantitatively enter the inner cavity of the inner shell 3 and mix with the atomized fragrance. When the through groove 11 on the inner shell 3 rotates to the lower position, the Chinese medicine granules that have been mixed with the fragrance in the inner shell 3 can fall into the lower chamber of the outer shell 7. During one rotation of the inner shell 3, the inner shell 3 can perform one feeding, mixing and discharging action, thereby dividing the large amount of Chinese medicine granules in the outer shell 7 into several smaller groups for mixing, further improving the uniformity of mixing between the Chinese medicine granules and the fragrance.

[0030] Meanwhile, under the transmission action of the planetary gear set 8, the outer shell 7 can rotate at a relatively low speed, and all the Chinese medicine granules in its upper chamber are mixed with spices. When the mixture flows into the lower chamber of the outer shell 7, the relative positions between the upper and lower chambers of the outer shell 7 are reversed. This allows the Chinese medicine granules that have been mixed with spices to flow back into the inner cavity of the inner shell 3, or to be mixed again by introducing atomized spices, or to be directly "tumbled" and stirred between the Chinese medicine granules, further improving the mixing effect between the Chinese medicine granules and spices.

[0031] like Figure 4 As shown, in this technical solution, the inner wall of the inner shell 3 is provided with a spiral-shaped rib plate 10 arranged along the rotation direction of the inner shell 3, and the number of rib plates 10 is arranged in a ring array according to the inner diameter of the inner shell 3, thereby effectively improving the frictional resistance between the Chinese medicine granules and the inner wall of the inner shell 3, so that the Chinese medicine granules can be carried to a higher position and scattered down, further improving the contact and mixing effect between them and the atomized fragrance.

[0032] In this technical solution, the speed at which the Chinese medicine granules stored in the upper chamber of the outer shell 7 flow into the inner shell 3 is directly proportional to the speed at which the outer shell 7 rotates under the transmission action of the planetary gear set 8. Before the outer shell 7 rotates to a 45° angle, the fragrance stored in its upper chamber can completely flow into the inner cavity of the inner shell 3 and mix with the atomized fragrance, and all fall into the lower chamber of the outer shell 7. This facilitates feeding or discharging the granules, and prevents any remaining Chinese medicine granules from the previous feeding from remaining in the inner cavity of the outer shell 7.

[0033] In this technical solution, the drive shaft 2 and the pressure storage tank 9 are connected by a hose, and one end of the hose is connected to the bottom of the pressure storage tank 9. Under the action of compressed air, all the fragrance stored in the pressure storage tank 9 can be squeezed and delivered to the nozzle 6. At the same time, when squeezing and delivering the fragrance, the quantitative delivery of the fragrance can be guaranteed, and the fragrance liquid level in the pressure storage tank 9 will not drop, causing it to not contact the end of the hose and resulting in a large amount of compressed air doing useless work.

[0034] In this technical solution, in the initial state, the nozzle 6 is located above the center of the inner shell 3, thereby effectively preventing the herbal particles that enter the inner cavity of the inner shell 3 through the through groove 11 from clogging the nozzle 6 during the feeding process.
