Description

[0001] The present invention relates to the technical field of liquid medicine extraction, and particularly relates to a liquid medicine extraction tank capable of filtering internal medicinal residues. Background Art

[0002] Liquid medicine refers to a liquid preparation containing drug components, and liquid medicine extraction refers to the process of extracting the effective components from medicinal materials. Liquid medicine extraction is of great significance for improving the efficacy of medicinal materials and facilitating pharmaceutical preparations.

[0003] During the process of extracting liquid medicine with existing devices, generally, medicinal materials are mixed with clear water, and then through high-temperature steaming, the effective components in the medicinal materials can enter the water. Finally, the clear water with the effective components of the medicinal materials is taken out to complete the liquid medicine extraction. However, during the process of liquid medicine extraction with existing devices, the medicinal materials and clear water are usually in a state of direct mixing at the bottom of the extraction tank. After the liquid medicine extraction is completed, there will be a large amount of fine medicinal residues in the liquid medicine, resulting in a decrease in the purity of the liquid medicine.

[0004] Therefore, in view of the above problems, a liquid medicine extraction tank capable of filtering internal medicinal residues is now developed, which can achieve solid-liquid separation and discharge during the liquid medicine extraction process, and avoid the mixing of medicinal residues in the liquid medicine. Summary of the Invention

[0017] 2. The present invention drives the rotating frame to rotate through the output shaft of the first driving motor, so that the rotating frame can be engaged with the connecting rod, and the rotating frame pushes the connecting rod, thereby enabling the fixed rod to drive the sliding frame to rotate, accelerating the mixing speed between the medicinal materials and the clear water, and improving the efficiency of medicinal liquid extraction.

[0018] 3.

Detailed implementation manners

[0031] The following will further illustrate the present invention in combination with specific embodiments. It should also be noted that unless otherwise clearly defined and limited, terms such as: setting, installation, connection, and coupling should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. 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.

[0032] A liquid medicine extraction tank capable of filtering internal medicinal residues, as Figure 1 andFigure 2 As shown in the figure, it includes an extraction tank 1, a water inlet assembly 2, a feed inlet assembly 3, a hydraulic cylinder 4, a cover plate 5, a liquid outlet pipe 6 and a filtering mechanism 7. The upper left side of the extraction tank 1 is connected to the water inlet assembly 2, and the upper right side of the extraction tank 1 is connected to the feed inlet assembly 3. Both the water inlet assembly 2 and the feed inlet assembly 3 include a guide pipe, a shielding cover and a locking member. Guide pipes are connected to the upper left side and the upper right side of the extraction tank 1 respectively. Shielding covers are rotatably connected to the guide pipes, and a plurality of locking members for locking the shielding covers are connected to the guide pipes. The lower left side of the extraction tank 1 is connected to the hydraulic cylinder 4 by bolts, and the lower part of the extraction tank 1 is rotatably connected to the cover plate 5. The left side of the cover plate 5 is connected to the telescopic end of the hydraulic cylinder 4. The front side of the lower part of the extraction tank 1 is connected to the liquid outlet pipe 6 for discharging the medicinal liquid. A filtering mechanism 7 for separating and mixing is provided inside the extraction tank 1.

[0033] It should be noted that when extracting the medicinal liquid from the medicinal materials, first send the medicinal materials into the extraction tank 1 through the feed inlet assembly 3 so that the medicinal materials fall on the filtering mechanism 7. Then, introduce clear water into the extraction tank 1 through the water inlet assembly 2. After discharging the materials, close the feed inlet assembly 3 and the water inlet assembly 2. Then start high-temperature steaming of the extraction tank 1 so that the medicinal materials can fully blend with the clear water to obtain the medicinal liquid. During the mixing process, the filtering mechanism 7 can block and limit the medicinal materials. After the operation, take out the medicinal liquid through the liquid outlet pipe 6. Then control the hydraulic cylinder 4 to open the cover plate 5 and push the filtering mechanism 7 downward. Finally, take out the medicinal residues.

[0034] As Figures 2 - 4 shown in the figure, the filtering mechanism 7 includes a fixed frame 71, a rotating frame 72, a sliding frame 73 and a filtering component 74. The fixed frame 71 is connected to the middle position inside the extraction tank 1. The lower part of the fixed frame 71 is rotatably connected to the rotating frame 72. The sliding frame 73 is slidably connected to the rotating frame 72. The filtering component 74 is connected to the sliding frame 73. The filtering component 74 includes a mounting seat, a sector-shaped filter net and a pull ring. Four mounting seats are evenly connected to the bottom of the sliding frame 73. The sector-shaped filter nets are rotatably connected to the mounting seats. Pull rings are connected to the bottoms of the sector-shaped filter nets.

[0035] It should be noted that during the process of steaming and extracting the medicinal liquid from the medicinal materials, after the medicinal materials are sent into the extraction tank 1 through the feeding port assembly 3, the medicinal materials will all fall on the filtering assembly 74. Then, as the clear water enters the extraction tank 1, the feeding port assembly 3 and the water inlet assembly 2 are both closed, and the extraction tank 1 starts to be heated at a high temperature. The medicinal materials inside the extraction tank 1 begin to continuously blend with the clear water to produce the medicinal liquid. At this time, during the blending process, the filtering assembly 74 can limit and block the solid medicinal materials to prevent the medicinal material residues from mixing with the extracted medicinal liquid. After the extraction of the medicinal liquid is completed, the operator extracts the medicinal liquid through the liquid outlet pipe 6. Then, as the cover plate 5 is opened, the sliding frame 73 needs to be pulled downward, so that the filtering assembly 74 moves downward until the filtering assembly 74 moves to the lower opening of the extraction tank 1, and then the filtering assembly 74 is opened to enable the medicinal residues on the filtering assembly 74 to be quickly discharged. To sum up, by isolating and placing the medicinal materials through the filtering assembly 74, solid-liquid separation is achieved during the extraction of the medicinal liquid, preventing the medicinal material residues from mixing with the medicinal liquid and resulting in the medicinal residues being mixed in the extracted medicinal liquid. After the extraction is completed, by pushing the sliding frame 73, the isolated medicinal residues can be quickly processed, improving the efficiency of medicinal liquid extraction and medicinal residue treatment.

[0036] As Figure 2 , Figure 5 and Figure 6 shown, it further includes a rotating mechanism 8. The rotating mechanism 8 includes a fixed rod 81, a connecting rod 82, a first spring 83, a rotating frame 84, and a first driving motor 85. Four fixed rods 81 are evenly connected to the bottom of the sliding frame 73. The bottoms of the fixed rods 81 are all slidably connected to the connecting rods 82. A first spring 83 is connected between each connecting rod 82 and the adjacent fixed rod 81. The first springs 83 are all located inside the adjacent connecting rods 82, and the first springs 83 can buffer the connecting rods 82. The bottom of the cover plate 5 is bolted with a first driving motor 85. A rotating frame 84 is connected to the output shaft of the first driving motor 85. The rotating frame 84 can push the connecting rods 82, and the sides of the rotating frame 84 in contact with the adjacent connecting rods 82 are all inclined surface structures.

[0037] It should be noted that in order to improve the efficiency of liquid medicine extraction, during the high-temperature cooking of medicinal materials and clear water, the first driving motor 85 is started. The output shaft of the first driving motor 85 drives the rotating frame 84 to rotate, so that the rotating frame 84 pushes the adjacent connecting rod 82, causing the connecting rods 82 to all slide upward by a small distance. At this time, the corresponding first springs 83 are all compressed under force, and at the same time, the rotating frame 84 is engaged with the adjacent connecting rods 82 at this time. As the rotating frame 84 continues to rotate, the rotating frame 84 will push the connecting rods 82 to rotate, so that the fixed rods 81 all start to rotate. At this time, the fixed rods 81 will drive the sliding frame 73 to rotate, and at the same time, the rotating frame 72 will continuously rotate, thereby accelerating the mixing speed between the medicinal materials and the clear water and improving the liquid medicine extraction efficiency. After the extraction is completed, just turn off the first driving motor 85. To sum up, the output shaft of the first driving motor 85 drives the rotating frame 84 to rotate, so that the rotating frame 84 can be engaged with the connecting rod 82, and the rotating frame 84 pushes the connecting rod 82, so that the fixed rod 81 drives the sliding frame 73 to rotate, accelerating the mixing speed between the medicinal materials and the clear water and improving the liquid medicine extraction efficiency.

[0038] As Figure 2 and Figure 7 shown, it further includes a locking mechanism 9. The locking mechanism 9 includes a limiting member 91, a fixing plate 92, a connecting rod 93 and a lifting frame 94. Four limiting members 91 are evenly connected to the bottom of the sliding frame 73. The fixing plates 92 are all slidably connected to the limiting members 91. The fixing plates 92 are used to lock and fix the filtering assembly 74. Lifting frames 94 are connected to the non-adjacent sides of the connecting rods 82. The lifting frames 94 are slidably connected to the adjacent fixed rods 81, and a connecting rod 93 is rotatably connected between the lifting frames 94 and the adjacent fixing plates 92.

[0039] It should be noted that as the connecting rods 82 are all pushed by the rotating frame 84 and start to slide upward, at this time, the connecting rods 82 will drive the adjacent lifting frames 94 to move upward, so that the lifting frames 94 will drive the adjacent connecting rods 93 to rotate, and push the fixing plates 92 to slide toward the side close to each other, thereby blocking and limiting the adjacent filtering assemblies 74, and then locking the filtering assemblies 74 to prevent the medicinal materials from being too heavy and causing the filtering assemblies 74 to accidentally open, resulting in the direct mixing of the medicinal materials and the clear water. To sum up, the rotating frame 84 drives the connecting rod 82 to move upward, so that the lifting frame 94 drives the connecting rod 93 to rotate, and then the fixing plates 92 lock the filtering assemblies 74 to prevent the filtering assemblies 74 from accidentally opening, resulting in abnormalities during the solid-liquid separation and discharge.

[0040] As Figure 2 and Figure 8As shown in the figure, it further includes a scraping mechanism 10. The scraping mechanism 10 includes a magnetic scraping frame 101, a mounting frame 102, and a second spring 103. The mounting frame 102 is connected to the sliding frame 73. The magnetic scraping frame 101 is slidably connected to the front, rear, left, and right sides of the mounting frame 102. The magnetic scraping frame 101 can be adsorbed to the fixed frame 71 and clean the attached medicinal residues at the same time. The non-adjacent sides of the magnetic scraping frame 101 are all arc-shaped structures and can fit with the fixed frame 71. A second spring 103 is connected between the magnetic scraping frame 101 and the mounting frame 102.

[0041] It should be noted that in the initial state, the second springs 103 are all in a state of being stretched by force. As the sliding frame 73 starts to slide downward, at this time, the sliding frame 73 will drive the mounting frame 102 to move downward, so that the mounting frame 102 drives the magnetic scraping frames 101 to slide downward. As the magnetic scraping frames 101 move downward, in this process, the magnetic scraping frames 101 will scrape the medicinal residues attached to the fixed frame 71, and at the same time, the magnetic scraping frames 101 will start to contract and reset along the inner wall of the fixed frame 71. At this time, the second springs 103 gradually start to return to the non-force state. When the sliding frame 73 continues to slide downward, the magnetic scraping frames 101 will all be detached from the adsorption state with the fixed frame 71. At this time, under the action of the second springs 103, the magnetic scraping frames 101 will all contract and move toward the side close to each other. To sum up, by driving the mounting frame 102 to slide downward through the sliding frame 73, the magnetic scraping frames 101 scrape most of the medicinal residues attached to the inner wall of the fixed frame 71. In this process, the second springs 103 continuously buffer the magnetic scraping frames 101 until the magnetic scraping frames 101 are detached from the fixed frame 71, and the second springs 103 will drive the magnetic scraping frames 101 to fully contract.

[0042] As Figure 2 and Figure 9 As shown in the figure, it further includes a flushing mechanism 11. The flushing mechanism 11 includes a second driving motor 111, a gear 112, a nozzle 113, and a water inlet pipe 114. The second driving motor 111 is connected to the upper side of the rear part of the extraction tank 1 by bolts. The nozzle 113 is rotatably connected to the top of the extraction tank 1. The water inlet pipe 114 is connected to the top of the nozzle 113. Gears 112 are connected to the upper part of the nozzle 113 and the output shaft of the second driving motor 111 respectively, and the gears 112 mesh with each other.

[0043] It should be noted that after the medicinal liquid extraction is completed, take the medicine and clean the inside of the extraction tank 1 to avoid the influence of residual medicinal residues on subsequent operations. At this time, the water supply device can be connected and communicated with the water inlet pipe 114, and then the second driving motor 111 is started. The output shaft of the second driving motor 111 rotates to drive the gears 112 to start rotating, so that the nozzle 113 starts to rotate and spray clean water, achieving the effect of comprehensively cleaning the inside of the extraction tank 1.

[0044] As Figure 2 and Figure 10 shown, it further includes a reinforcement mechanism 12. The reinforcement mechanism 12 includes a first fixing block 121, a second fixing block 122, and a reinforcement ring 123. The right side of the cover plate 5 is connected to the first fixing block 121. The reinforcement ring 123 is rotatably connected to the first fixing block 121. The lower right side of the extraction tank 1 is connected to the second fixing block 122. The second fixing block 122 can be clamped with the reinforcement ring 123 to improve the stability of the cover plate 5.

[0045] It should be noted that in order to prevent the internal pressure of the extraction tank 1 from being too high, which may cause the hydraulic cylinder 4 to be difficult to support and control the cover plate 5, the reinforcement ring 123 is clamped with the second fixing block 122, so that the cover plate 5 and the extraction tank 1 can be stably clamped, preventing the cover plate 5 from accidentally rotating and opening. When it is necessary to open the cover plate 5, the reinforcement ring 123 and the second fixing block 122 can be disengaged from the clamping connection.
