Description

Technical Field

[0001] This invention relates to the field of solvent separation and extraction equipment technology, and in particular to a traditional Chinese medicine extraction tank with automatic slag discharge capability. Background Technology

[0002] Extraction tanks are commonly used leaching extraction equipment in the pharmaceutical and chemical industries, especially suitable for the leaching extraction of components contained in plant products. The working principle of an extraction tank is a simple decoction process. Chinese herbal medicines are soaked in water and heated with steam. After a certain period of time, the effective components are extracted. After extraction, the liquid and residue are discharged from the bottom slag outlet of the extraction tank. However, existing extraction tanks are usually cone-shaped at the bottom. When discharging residue, the residue blocks the slag outlet, making it difficult to discharge. Often, the operator needs to use an iron rod to loosen the residue blocking the slag outlet before the residue can be discharged. When handling high-temperature residue, it is easy to cause safety accidents and poses safety hazards. Therefore, the prior art proposes a convenient slag removal device for preparing traditional Chinese medicine ointments, patent number CN201810959364.0. Through the arrangement of the traditional Chinese medicine basket, push plate, and lifting drive mechanism, the slag removal from the extraction tank is simple and convenient, with good slag removal effect and efficiency. The heating jacket heats the traditional Chinese medicine and water in the extraction tank, resulting in better extraction effect and higher extraction efficiency. The safety valve balances the external pressure and the pressure inside the extraction tank, ensuring safety. When slag removal is needed, the cylinder drives the push rod to lift the traditional Chinese medicine basket out of the extraction tank and collect it; when descent is needed, the cylinder drives the push rod to lower the traditional Chinese medicine basket to the appropriate position inside the extraction tank. The motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring blades to stir the traditional Chinese medicine slag, improving the soaking or heating extraction effect. The multiple stirring nails disperse the traditional Chinese medicine in the basket, making stirring less strenuous.

[0003] However, when the lifting drive mechanism of this device pushes the push plate upward to push the Chinese medicine residue out of the extraction tank, a large amount of residue is deposited at the bottom of the Chinese medicine frame. The Chinese medicine frame needs to be removed from the lifting mechanism to clean the residue at the bottom. In addition, the lid on top of the Chinese medicine frame needs to be removed before disassembling the Chinese medicine frame. The lid is also equipped with a complex and heavy drive mechanism, which further increases the difficulty of slag removal. After the slag is removed, it needs to be reassembled and reset in sequence, which is quite inconvenient. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a traditional Chinese medicine extraction tank with automatic slag discharge capability, thereby resolving the issues described in the background section.

[0007] As a further embodiment of the present invention: the slag discharge assembly consists of a servo motor, a hydraulic cylinder, a transfer plate, a connecting plate, a filter screen, a transmission rod, an extension column, and a stirring blade; Specifically, a servo motor is fixed inside the upper part of the main tank, and hydraulic cylinders are vertically fixed at the left and right ends of the upper part of the main tank. A transition plate is fixed at the bottom of the push rod at the output end of the two hydraulic cylinders. A connecting plate is fixed at the lower outer wall of the transition plate. A filter screen is fixed at the bottom of the connecting plate. A transmission rod is connected to the bottom of the transmission shaft at the output end of the servo motor. An extension column is embedded inside the lower part of the transmission rod. An agitator is fixed at the lower outer wall of the extension column.

[0008] As a further aspect of the present invention: the bottom end of the extension column is embedded in the middle of the filter screen, and a fixing plate with a cross-sectional area larger than that of the extension column is fixed at the bottom end of the extension column; the outer wall of the filter screen is in close contact with the inner wall of the inner cylinder, and the filter screen moves up and down vertically in the inner cylinder.

[0009] As a further aspect of the present invention: the upper surface of the guide plate is provided with an inclined surface that is lower on the left and higher on the right, and a column is vertically fixed on the upper surface of the guide plate. The column is embedded in the filter hole inside the filter screen, and the upper surface of the column and the upper surface of the filter screen are on the same horizontal plane.

[0010] As a further aspect of the present invention: three connecting plates are fixed vertically in a circular shape on the lower outer side of the adapter plate, and three inner sliding grooves are provided in the vertical opening of the inner wall of the inner cylinder. The connecting plates are precisely embedded in the inner sliding grooves on the inner wall of the inner cylinder, and the cross-sectional area of ​​the inner sliding grooves is the same as that of the connecting plates.

[0011] As a further aspect of the present invention: three sets of stirring blades are equidistantly arranged from top to bottom on the lower part of the outer wall of the extension column, the rotation area of ​​the stirring blades is the same as the cross-sectional area of ​​the filter screen, and the bottom end of the stirring blade at the bottom of the outer wall of the extension column is in close contact with the upper surface of the filter screen.

[0012] As a further aspect of the present invention: the extension column is arranged in a pentagonal shape, the outer wall of the extension column is closely attached to the inner wall of the transmission rod, and the extension column moves up and down vertically inside the transmission rod.

[0013] As a further aspect of the present invention: five slots are provided in the vertical opening at the middle of the outer wall of the transmission rod, the middle of the slots and the middle of the stirring blade are on the same vertical horizontal plane, and the width of the slots is the same as the width of the stirring blade.

[0014] As a further aspect of the present invention: a slag discharge port is provided at the upper right side opening of the inner cylinder and the main tank, and the slag discharge port is located at the upper left side of the outer frame. When the filter screen moves upward in the inner cylinder and is close to the bottom of the transmission rod, the upper surface of the filter screen and the bottom end of the slag discharge port are both on the same horizontal plane.

[0015] 1. After the Chinese medicine is soaked and extracted in the water in the inner cylinder, two hydraulic cylinders simultaneously pull the extension column upward at the bottom of the transmission rod through the push rod, adapter plate, connecting plate, and filter screen at their bottom output ends. At this time, the medicine liquid falls through the filter holes in the filter screen, filtering out the medicine residue in the medicine liquid. When the filter screen moves up in the inner cylinder and sticks tightly to the bottom of the transmission rod, because the lowest set of stirring blades of the extension column is in close contact with the upper surface of the filter screen, the servo motor drives the stirring blades to rotate through the transmission rod and the extension column. The lowest set of stirring blades pushes the medicine residue filtered out on the upper surface of the filter screen to slide on the surface of the filter screen. At this time, the medicine residue generates centrifugal force and passes through the slag discharge port in the inner cylinder and the main tank into the outer frame, falling into the collection box at the bottom of the outer frame for storage. This can quickly separate the medicine residue and medicine liquid, and can quickly collect the separated medicine residue. The slag discharge effect is good and it is not easy to leave residue, making it more convenient to use.

[0016] 2. When the Chinese medicine and water are poured into the inner cylinder of the main tank for soaking and extraction, the servo motor drives the stirring blades through the transmission rod and extension column to stir the Chinese medicine and water. At the same time, the two hydraulic cylinders pull or push the extension column repeatedly up and down at the bottom of the transmission rod through the push rod, adapter plate, connecting plate and filter screen at its bottom output end, adjusting the stirring height of the Chinese medicine and water, so that the medicine and water are fully mixed. At the same time, the circulation pump can also introduce the water and medicine residue that have settled at the bottom of the inner cylinder from bottom to top into the feed hopper, so that the water and medicine residue that have settled at the bottom of the inner cylinder fall into the water at the top of the inner cylinder, making the Chinese medicine and water mix more evenly, and at the same time, it can prevent the Chinese medicine from settling at the bottom of the water or floating on the surface of the water for a long time, further improving the soaking and extraction effect of the Chinese medicine.

[0018] Legend: Main tank 1, feed hopper 101, discharge pipe 102, solenoid valve 103, circulation pump 104, outer frame 2, collection box 201, inner cylinder 202, servo motor 3, hydraulic cylinder 301, adapter plate 302, connecting plate 303, filter screen 304, transmission rod 305, extension column 306, stirring blade 307, guide plate 308, column 309. Detailed Implementation

[0019] Example 1, please refer to Figure 1-7 An automatic slag discharge extraction tank for traditional Chinese medicine includes a main tank body 1, a feed hopper 101, a discharge pipe 102, and a solenoid valve 103. The feed hopper 101 is embedded and fixed at both the left and right ends of the top of the main tank body 1. The discharge pipe 102 is horizontally embedded on the left side of the bottom of the main tank body 1. The solenoid valve 103 is fixed in the middle of the discharge pipe 102. The circulation pump 104 is fixed to the front bottom of the main tank body 1 by a bracket. The outer frame 2 is vertically fixed on the right side of the main tank body 1. The collection box 201 is horizontally embedded at the bottom of the outer frame 2. The inner cylinder 202 is fixed at the bottom of the main tank body 1. The slag discharge assembly is provided inside the main tank body 1. The guide plate 308 is fixed at the bottom of the inner cylinder 202.

[0020] The inlet end of the discharge pipe 102 is embedded in the bottom left side of the inner cylinder 202. The inlet end of the circulation pump 104 is connected to the inside right side of the discharge pipe 102 through a pipe. The outlet end of the circulation pump 104 is connected to the inside of the two feed hoppers 101 through a pipe. When the Chinese medicine and water are poured into the inner cylinder 202 of the main tank 1 for soaking and extraction, the circulating pump 104 can introduce the water and small medicinal residues deposited at the bottom of the inner cylinder 202 from bottom to top into the feed hopper 101. This allows the water and medicinal residues deposited at the bottom of the inner cylinder 202 to fall into the water at the top of the inner cylinder 202 along the feed hopper 101, making the Chinese medicine and water mix more evenly. This can prevent the Chinese medicine from being deposited at the bottom of the water or floating on the surface for a long time, and further improve the soaking and extraction effect of the Chinese medicine. After the solenoid valve 103 in the drug discharge pipe 102 is opened, the drug liquid flows out from the drug discharge pipe 102.

[0021] Example 2, please refer to Figure 1-7 The difference between Example 2 and Example 1 is that the slag discharge assembly consists of a servo motor 3, a hydraulic cylinder 301, a transfer plate 302, a connecting plate 303, a filter screen 304, a transmission rod 305, an extension column 306, and a stirring blade 307. A servo motor 3 is fixed inside the upper part of the main tank 1. A hydraulic cylinder 301 is vertically fixed at the left and right ends of the upper part of the main tank 1. A transition plate 302 is fixed at the bottom of the push rod at the output end of the two hydraulic cylinders 301. A connecting plate 303 is fixed at the lower part of the outer wall of the transition plate 302. A filter screen 304 is fixed at the bottom of the connecting plate 303. A transmission rod 305 is connected to the bottom of the transmission shaft at the output end of the servo motor 3. An extension column 306 is embedded inside the lower part of the transmission rod 305. An stirring blade 307 is fixed at the lower part of the outer wall of the extension column 306. The bottom end of the extension column 306 is embedded in the middle of the filter screen 304. The bottom end of the extension column 306 is fixed with a fixing plate with a cross-sectional area larger than that of the extension column 306. The outer wall of the filter screen 304 is in close contact with the inner wall of the inner cylinder 202. The filter screen 304 moves up and down vertically in the inner cylinder 202. When the extension column 306 drives the fixed plate at its bottom to rotate, the filter screen 304 can pull and push the extension column 306 up and down in the transmission rod 305 by limiting the extension column 306 through the connecting plate. When the Chinese medicine and water are poured into the inner cylinder 202 of the main tank 1 for soaking and extraction, the servo motor 3 drives the stirring blade 307 to stir the Chinese medicine and water through the transmission rod 305 and the extension column 306. At the same time, the two hydraulic cylinders 301 pull or push the extension column 306 repeatedly up and down at the bottom of the transmission rod 305 through the push rod, the adapter plate 302, the connecting plate 303 and the filter screen 304 at their bottom output ends, so as to adjust the stirring height of the Chinese medicine and water, so that the medicine and water are fully mixed. At the same time, it can prevent the Chinese medicine from settling at the bottom of the water or floating on the surface of the water for a long time, further improving the soaking and extraction effect of the Chinese medicine. The upper surface of the guide plate 308 is provided with an inclined surface that is lower on the left and higher on the right. A column 309 is vertically fixed on the upper surface of the guide plate 308. The column 309 is embedded in the filter hole inside the filter screen 304. The upper surface of the column 309 and the upper surface of the filter screen 304 are on the same horizontal plane. When the two hydraulic cylinders 301 move to the bottom of the inner cylinder 202 simultaneously through the push rod, adapter plate 302, connecting plate 303 and filter screen 304 at their bottom output ends, the column 309 on the guide plate 308 will be embedded in the filter hole inside the filter screen 304, so as to clean the medicine residue stuck in the filter hole of the filter screen 304 and avoid the medicine residue stuck in the filter hole from affecting the solid-liquid separation speed of the medicine liquid; Three connecting plates 303 are vertically fixed in a ring shape on the lower outer side of the adapter plate 302. Three inner grooves are provided in the vertical opening of the inner wall of the inner cylinder 202. The connecting plates 303 are perfectly embedded in the inner grooves of the inner wall of the inner cylinder 202. The cross-sectional area of ​​the inner grooves is the same as that of the connecting plates 303. The connecting plate 303 limits the filter screen 304 by being embedded in the inner groove of the inner cylinder 202, so as to prevent the extension column 306 from rotating the filter screen 304 during the rotation process, and so that the filter holes inside the filter screen 304 are not on the same vertical horizontal plane as the column 309 on the guide plate 308. The connecting plate 303 is embedded in the inner groove to prevent the rotating stirring blade 307, which is in close contact with the inner wall of the inner cylinder 202, from contacting it and causing the stirring blade 307 to be unable to rotate normally. Three sets of stirring blades 307 are equidistantly arranged from top to bottom on the lower part of the outer wall of the extension column 306. The rotation area of ​​the stirring blades 307 is the same as the cross-sectional area of ​​the filter screen 304. The bottom end of the stirring blade 307 at the bottom of the outer wall of the extension column 306 is in close contact with the upper surface of the filter screen 304. When the filter screen 304 moves upward and closely adheres to the bottom of the transmission rod 305 in the inner cylinder 202, since the lowest set of stirring blades of the extension column 306 is always in close contact with the upper surface of the filter screen 304, the servo motor 3 drives the stirring blades 307 to rotate through the transmission rod 305 and the extension column 306. The lowest set of stirring blades 307 will push the dregs filtered out on the upper surface of the filter screen 304 to slide on the upper surface of the filter screen 304, and push the filtered filter screen 304 into the dregs discharge port for collection. The extension column 306 is arranged in a five-lobed column shape. The outer wall of the extension column 306 is closely attached to the inner wall of the transmission rod 305. The extension column 306 moves up and down vertically inside the transmission rod 305. Because the extension column 306 is arranged in a pentagonal shape, the servo motor 3 can still drive the extension column 306 to rotate normally through the transmission rod 305 during the process of the extension column 306 moving up and down inside the transmission rod 305.

[0022] Example 3, please refer to Figure 1-7 The difference between Embodiment 3 and Embodiment 2 is that the transmission rod 305 has five slots in the vertical opening at the middle of its outer wall. The middle of the slots and the middle of the stirring blade 307 are on the same vertical horizontal plane, and the width of the slots is the same as the width of the stirring blade 307. The main function of the five slots on the outside of the transmission rod 305 is that when the filter screen 304 moves up and is close to the bottom of the transmission rod 305, the stirring blade 307 on the extension column 306 will be embedded in the slots of the transmission rod 305, so as to avoid the stirring blade 307 directly contacting the transmission rod 305 and causing the filter screen 304 to be unable to move up normally in the inner cylinder 202. The inner cylinder 202 and the main tank 1 have a slag discharge port on the upper right side. The slag discharge port is located on the upper left side of the outer frame 2. When the filter screen 304 moves up in the inner cylinder 202 and is close to the bottom of the transmission rod 305, the upper surface of the filter screen 304 and the bottom end of the slag discharge port are on the same horizontal plane. When the filter screen 304 moves upward and closely adheres to the bottom of the transmission rod 305 in the inner cylinder 202, the bottommost set of stirring blades of the extension column 306 is in close contact with the upper surface of the filter screen 304. As the servo motor 3 drives the stirring blades 307 to rotate through the transmission rod 305 and the extension column 306, the bottommost set of stirring blades 307 will push the medicine residue filtered out from the upper surface of the filter screen 304 to slide on the upper surface of the filter screen 304, so that the medicine residue generates centrifugal force and passes through the slag discharge port in the inner cylinder 202 and the main tank 1 into the outer frame 2. Once the dregs enter the outer frame 2, they will fall into the collection box 201 at the bottom of the outer frame 2 due to gravity and be stored thereafter. The dregs can be processed by removing the collection box 201, thus achieving rapid collection of the separated dregs.

[0023] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
