Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing equipment technology, and more specifically, to a residue-liquid separator. Background Technology

[0002] Most commercially available Chinese herbal decoction equipment uses bagged decoction, which cannot meet the requirements of traditional loose decoction for separating and extracting the medicinal liquid. Some devices use a decoction tank, but manual filtration and separation of the dregs are still required after decoction.

[0003] Existing equipment and technologies for separating the decoction from the residue after decocting traditional Chinese medicine have the following main problems:

[0004] 1. Low separation efficiency: Traditional separation methods often take a long time and are inefficient, which cannot meet the needs of modern high-efficiency production.

[0005] 2. Incomplete extraction of medicinal liquid: The medicinal liquid in the residue was not fully squeezed out, resulting in a waste of medicinal efficacy, and the residue contained a lot of medicinal liquid, which affected subsequent processing.

[0006] 3. Complex equipment cleaning: After decoction, cleaning the equipment and related components is tedious and can easily cause cross-contamination of the medicinal liquid, affecting the quality of Chinese medicine.

[0007] 4. Insufficient automation: The existing separation equipment has a low level of automation, and operation requires manual intervention, which increases labor intensity and reduces production efficiency.

[0008] The limitations of the aforementioned existing technologies not only restrict the efficiency of decocting and extracting Chinese medicine, but also affect the quality and safety of Chinese medicine. Utility Model Content

[0009] The main purpose of this invention is to provide a residue-liquid separator to solve the problem that existing Chinese medicine decoction equipment cannot meet the requirements for separating and extracting medicinal liquid in traditional decoction methods.

[0010] To achieve the above objectives, this utility model provides a slag-liquid separator, comprising: a frame; a conveying device for conveying medicine barrels, the conveying device including a feeding conveyor line, an intermediate conveyor line, and a discharging conveyor line that are sequentially connected; an extrusion device connected to the frame and located above the intermediate conveyor line, the extrusion device having an extrusion end that can be raised and lowered, the extrusion end being able to extend into the medicine barrel on the intermediate conveyor line to extrude the slag inside the medicine barrel; and a cleaning device located at the intermediate conveyor line, the extrusion end of the extrusion device being able to extend into the cleaning device to clean the extrusion end.

[0011] Furthermore, the intermediate conveyor line is laterally movable relative to the frame and has a conveying position and a clearance position. When the intermediate conveyor line is in the conveying position, it is connected to the feeding conveyor line and the discharging conveyor line, and the extrusion end is located directly above the intermediate conveyor line. When the intermediate conveyor line is in the clearance position, it is staggered from the feeding conveyor line and the discharging conveyor line, and the intermediate conveyor line clears the area directly above the cleaning device.

[0012] Furthermore, the cleaning device can be raised and lowered. When the intermediate conveyor line is in the avoidance position, the intermediate conveyor line is misaligned with the top of the cleaning device. The cleaning device rises and the squeezing end descends, with the squeezing end extending into the cleaning device for cleaning.

[0013] Furthermore, the intermediate conveyor line includes: a sliding frame, which is laterally movable; a conveying roller, which is rotatably mounted on the sliding frame, and the medicine barrel is supported on the conveying roller and conveyed under the drive of the conveying roller; a transmission component, which passes through the side of the sliding frame and is threadedly engaged with the sliding frame; and a sliding drive component, which is drivenly connected to the transmission component and drives the sliding frame to move laterally through the transmission component.

[0014] Furthermore, the intermediate conveyor line also includes a guide member, which is mounted on a sliding frame. The guide member is positioned perpendicular to the conveying direction of the conveying device, and the sliding frame is moved along the guide member's direction.

[0015] Furthermore, the cleaning device includes: a cleaning tank, which is liftable, with a cleaning port on the inner wall of the cleaning tank, through which the cleaning fluid acts on the squeezing end inside the cleaning tank; and a cleaning drive unit, which is connected to the cleaning tank and drives the cleaning tank to move up and down.

[0016] Furthermore, the extrusion device includes: a pressing disc with an extrusion end, the pressing disc being vertically adjustable; and an extrusion drive connected to the pressing disc and driving the pressing disc to move vertically to extrude the medicinal residue.

[0017] Furthermore, the extrusion device also includes a cover, which is positioned above the pressing disc and moves up and down synchronously with the pressing disc. The cleaning device includes a cleaning tank. When the pressing disc is inserted into the tank, the cover is placed on the tank. When the pressing disc is inserted into the cleaning tank, the cover is placed on top of the cleaning tank and blocks the upper opening of the cleaning tank.

[0018] Furthermore, the cover has a nozzle and a nozzle channel communicating with the nozzle, through which liquid or gas is transported to the nozzle and sprayed onto the pressure plate.

[0019] Furthermore, the slag-liquid separator also includes a limiting component, which includes: a limiting member located at one end of the intermediate conveyor line near the discharge conveyor line, the limiting member being movable and capable of extending into or out of the conveying path of the medicine barrel to obstruct or avoid the conveying of the medicine barrel; and a limiting drive member connected to the limiting member and driving the limiting member to obstruct or avoid the conveying of the medicine barrel.

[0020] Furthermore, the sludge-liquid separator also includes a positioning component, which includes: a positioning element having a positioning recess, the positioning element being movably configured, and the positioning element and the limiting element being located at different positions around the medicine barrel, the medicine barrel being located within the positioning recess when the positioning element positions the medicine barrel; and a positioning drive element being drivenly connected to the positioning element and driving the positioning element to approach or move away from the medicine barrel in order to position or avoid the medicine barrel.

[0021] By employing the technical solution of this utility model, and by incorporating both a squeezing device and a cleaning device, the squeezing device can both separate the medicinal residue and clean the squeezing end after the first separation. This ensures that any residual medicinal liquid or residue at the squeezing end will not affect subsequent separations. Specifically, a medicine barrel containing medicinal decoction pieces is conveyed to an intermediate conveyor line via a feeding conveyor line. Once on the intermediate conveyor line, the squeezing device activates, lowering its squeezing end and extending it into the medicine barrel to squeeze the medicinal decoction pieces and separate the liquid from the residue. After the liquid is transferred to the packaging equipment, the squeezing plate moves upward, detaches from the medicine barrel, and resets. The medicine barrel can then continue to be conveyed, exiting the equipment via a discharge conveyor line. After the liquid separation, the squeezing end can move downward again and extend into the cleaning device to clean it, removing any residual liquid and residue. After cleaning, the squeezing end rises back to its original position. The above setup can quickly and cleanly separate the decoction and dregs of decocted Chinese herbal medicine, while cleaning the squeezing device that comes into contact with the decoction to ensure the cleanliness of the equipment, prevent cross-contamination of the decoction, improve the automation level and production efficiency of Chinese herbal medicine decoction, and meet the needs of traditional decoction separation and extraction of decoction.

[0037] To address the problem that existing Chinese medicine decoction equipment cannot meet the requirements for separating and extracting medicinal liquid using traditional decoction methods, this invention provides a residue-liquid separator.

[0038] Example 1

[0039] like Figures 1 to 9 The slag-liquid separator shown includes a frame 10, a conveying device 20 for conveying medicine barrels 70, a pressing device 30, and a cleaning device 40. The conveying device 20 includes a feed conveyor 21, an intermediate conveyor 22, and a discharge conveyor 23 that are sequentially connected. The intermediate conveyor 22 is laterally movable relative to the frame 10 and has a conveying position and a clearance position. The pressing device 30 is connected to the frame 10 and is located above the intermediate conveyor 22. The pressing device 30 has a pressing end that can be raised and lowered. When the intermediate conveyor 22 is in the conveying position, it is connected to the feed conveyor 21 and the discharge conveyor 23. The pressing end is located directly above the intermediate conveyor 22 and can extend into the medicine barrel 70 on the intermediate conveyor 22 to press the medicine residue in the medicine barrel 70. The cleaning device 40 is located at the intermediate conveyor 22. When the intermediate conveyor 22 moves laterally to a clearance position to avoid the cleaning device 40, the pressing end of the pressing device 30 can extend into the cleaning device 40, and the cleaning device 40 cleans the pressing end.

[0040] This embodiment incorporates a squeezing device 30 and a cleaning device 40. The squeezing device 30 can both separate the medicinal residue and the cleaning device 40 can clean the squeezing end after each separation, ensuring that any residual medicinal liquid or residue will not affect subsequent separations. Specifically, a medicine barrel 70 containing medicinal decoction pieces is conveyed to an intermediate conveyor line 22 via a feeding conveyor line 21. Once on the intermediate conveyor line 22, the squeezing device 30 activates, lowering its squeezing end and extending into the medicine barrel 70 to squeeze the medicinal decoction pieces and separate the liquid from the residue. After the liquid is transferred to the packaging equipment, the squeezing plate moves upward, detaches from the medicine barrel 70, and resets. The medicine barrel 70 can then continue to be conveyed, exiting the equipment via a discharge conveyor line 23. After the liquid separation, the squeezing end can move downward again and extend into the cleaning device 40 to clean it, removing any residual liquid and residue. After cleaning, the squeezing end rises back to its original position. The above setup can quickly and cleanly separate the decoction and dregs of the prepared Chinese herbal medicine, while cleaning the squeezing device 30 that comes into contact with the decoction, ensuring the cleanliness of the equipment, preventing cross-contamination of the decoction, improving the automation level and production efficiency of Chinese herbal medicine decoction, and meeting the needs of traditional decoction separation and extraction of decoction.

[0041] In this embodiment, the extrusion end of the extrusion device 30 and the cleaning device 40 are arranged vertically aligned, with the cleaning device 40 located directly below the extrusion device 30, and an intermediate conveyor line 22 is provided between them. Considering that the intermediate conveyor line 22 may have a certain impact on the cleaning of the extrusion end, the intermediate conveyor line 22 in this embodiment is arranged in a movable manner. Specifically, the intermediate conveyor line 22 is laterally movable relative to the frame 10 and has a conveying position and a clearance position. When the intermediate conveyor line 22 is in the conveying position, it connects with the feeding conveyor line 21 and the discharging conveyor line 23, allowing normal conveying of the medicine barrel 70. At the same time, the extrusion end is located directly above the intermediate conveyor line 22, allowing it to move downwards and extend into the medicine barrel 70 to extrude the medicine residue inside. After the medicine liquid is separated, or immediately after the medicine barrel 70 is conveyed out of the equipment, the intermediate conveyor line 22 moves laterally to the clearance position. At this time, the intermediate conveyor line 22 is staggered from the feeding conveyor line 21 and the discharging conveyor line 23, and it no longer performs a conveying function. At the same time, the intermediate conveyor line 22 avoids the area directly below the extrusion end and directly above the cleaning device 40, allowing the extrusion end to descend and extend into the cleaning device 40 for cleaning, causing the residual medicine liquid and medicine residue on the extrusion end to fall off. After the extrusion end is cleaned, the extrusion end rises and resets. At this time, the intermediate conveyor line 22 resets to the conveying position and resumes its conveying function, thus continuing the conveying of the medicine barrel 70.

[0042] In this embodiment, in addition to the extrusion device 30 being height-adjustable, the cleaning device 40 is also height-adjustable to improve convenience during cleaning. This way, when the extrusion end needs cleaning, the intermediate conveyor line 22 is positioned to avoid it. At this time, the intermediate conveyor line 22 is offset from the top of the cleaning device 40, allowing the cleaning device 40 to rise as the extrusion end descends, ensuring the extrusion end can fully enter the cleaning device 40 for cleaning, guaranteeing cleaning reliability and improving cleaning efficiency. Of course, the cleaning device 40 can also be non-height-adjustable, in which case the lifting stroke of the extrusion end can be set to be larger, allowing the extrusion end to descend into the cleaning device 40.

[0043] like Figure 4 and Figure 5 As shown, in this embodiment, the intermediate conveyor line 22 includes a sliding frame 221, a conveying roller 222, a transmission component 223, and a sliding drive component 224. The sliding frame 221 is laterally movable relative to the frame 10, so as to... Figure 5 The direction of movement is vertical. The sliding frame 221 is the main part of the intermediate conveyor line 22. The conveying rollers 222 are rotatably mounted on the sliding frame 221. Multiple conveying rollers 222 can be provided, and they are arranged at intervals along the conveying direction, so that the medicine barrel 70 can be supported on the conveying rollers 222 and conveyed under the drive of the conveying rollers 222. The transmission component 223 passes through the side of the sliding frame 221 and is threadedly engaged with the sliding frame 221. The transmission component 223 can be a structure such as a lead screw. The axis of the lead screw can be set parallel to the axis of the conveying roller 222. With the setting of the sliding drive component 224, the sliding drive component 224 is driven to drive the transmission component 223. In this way, the sliding drive component 224 drives the transmission component 223 to rotate, and the transmission component 223 can drive the sliding frame 221 to move laterally through the threaded engagement, realizing the switching of the intermediate conveyor line 22 between the conveying position and the avoidance position. The sliding drive component 224 can be a component such as a motor.

[0044] The intermediate conveyor line 22 in this embodiment also includes a guide member 225. The guide member 225 can be a structure such as a guide rod. The guide member 225 is inserted on the sliding frame 221. The axis of the guide member 225, the axis of the transmission member 223, and the axis of the conveying roller 222 can be arranged in parallel. In this way, the guiding direction of the guide member 225 is the moving direction of the sliding frame 221, and this direction is perpendicular to the conveying direction of the conveying device 20. This allows the sliding frame 221 to move only laterally between the conveying position and the avoidance position under the guidance of the guide member 225 along the guiding direction of the guide member 225.

[0045] In this embodiment, the intermediate conveyor line 22 is made entirely of stainless steel, which effectively prevents various liquids from adhering to and corroding the parts.

[0046] like Figure 9 As shown, the feeding conveyor line 21 and the discharging conveyor line 23 in this embodiment have roughly the same structure, both including a frame and rollers. The frame can be connected to the machine frame 10, or only docked to the side of the machine frame 10. The rollers are rotatably mounted on the frame, so that the feeding conveyor line 21 and the discharging conveyor line 23 can cooperate with the intermediate conveyor line 22 to transport the medicine barrel 70. Since the feeding conveyor line 21 and the discharging conveyor line 23 do not need to move laterally, they do not need to be equipped with the transmission component 223, sliding drive component 224, and other components of the intermediate conveyor line 22.

[0047] like Figure 8 As shown, in this embodiment, the cleaning device 40 includes a cleaning tank 41 and a cleaning drive unit 42. The cleaning tank 41 is the main body for accommodating and cleaning the extrusion end. The cleaning tank 41 is designed to be height-adjustable relative to the frame 10. The inner wall of the cleaning tank 41 is provided with a cleaning port and corresponding pipes. The cleaning port may include a water inlet, a water outlet, a water outlet, a spray nozzle, etc. The cleaning liquid can be injected into the cleaning tank 41 through the water inlet and applied to the extrusion end inside the cleaning tank 41 through the spray nozzle, thereby cleaning the extrusion end. The wastewater after cleaning can be discharged through the water outlet and the water outlet. The cleaning drive unit 42 may be a cylinder or other component, which is connected to the cleaning tank 41 and drives the cleaning tank 41 to move up and down. Guide rails, guide rods, or other components may also be provided between the cleaning tank 41 and the frame 10 as needed to ensure the stability of the lifting and lowering of the cleaning tank 41.

[0048] like Figure 3 As shown, the extrusion device 30 in this embodiment includes a pressing disc 31 and an extrusion drive 32. The pressing disc 31 has an extrusion end and serves as the main component for extruding the medicinal residue. The pressing disc 31 can be raised and lowered, allowing it to descend to extrude the medicinal residue or to descend into the washing tank 41 for washing. The extrusion drive 32 can be a cylinder or similar component, which is connected to the pressing disc 31 and drives the pressing disc 31 to move up and down to extrude the medicinal residue.

[0049] In this embodiment, multiple through holes are provided on the pressing disc 31. This allows the squeezed medicinal liquid to collect through the through holes, preventing the medicinal liquid squeezed out of the middle part of the dregs from being unable to be discharged, thus improving the extraction and separation effect. At the same time, this embodiment provides multiple extrusion drive units 32. Taking three as an example, all three extrusion drive units 32 are mounted on the frame 10 and connected to the pressing disc 31. The connection positions of the cylinder rods of the three extrusion drive units 32 and the pressing disc 31 are equally spaced along the circumference of the pressing disc 31. This allows the three extrusion drive units 32 to simultaneously apply extrusion force to the pressing disc 31, providing a pressure of about 100 to 700 kg, thereby effectively separating the medicinal liquid and the dregs. At the same time, the medicinal liquid inside the dregs is squeezed out, improving the separation effect of the dregs. Furthermore, due to the equal spacing, the force is applied evenly, making the extrusion more uniform.

[0050] In this embodiment, the pressing disc 31 has a downward-facing recess in the middle, and the inner wall of the recess also has through holes. This recess allows the liquid medicine squeezed out when the pressing disc 31 presses down on the medicine residue to collect in the recess. Simultaneously, this embodiment includes a suction pipe on the pressing device 30, with its suction port located in the recess. This allows the squeezed liquid medicine to be drawn into the packaging equipment through the suction pipe, thus achieving the collection and transfer of the liquid medicine. This method ensures that the medicine residue is fully compressed while maximizing the collection and transfer of the squeezed liquid medicine, guaranteeing sufficient separation and transfer of the medicine medicine.

[0051] In this embodiment, the extrusion device 30 also includes a cover 33, which is disposed above the pressing disc 31 and moves up and down synchronously with the pressing disc 31. The cover 33 is designed to address two main issues. First, the medicine barrel 70 is open at the top when it is conveyed to the intermediate conveyor line 22. In this case, the pressing disc 31 may squeeze the medicine residue, potentially causing liquid splashing. Therefore, in this embodiment, the cover 33 covers the medicine barrel 70 when the pressing disc 31 is inserted, thus blocking the opening and preventing liquid splashing. Second, the cover 33 can also be used with the cleaning tank 41. Since the cleaning tank 41 is also open at the top, when the pressing disc 31 is inserted into the cleaning tank 41, the cover 33 covers the top, blocking the opening and creating a closed cleaning chamber. This allows the pressing end to be thoroughly cleaned within the chamber, enabling a higher spray pressure without worrying about liquid splashing, thus improving the cleaning effect.

[0052] In this embodiment, in addition to the cleaning port on the inner wall of the cleaning tank 41, a nozzle and a nozzle channel communicating with the nozzle are provided on the cover 33. The nozzle, similar to a spray nozzle, can also introduce liquid into the cleaning chamber to assist in cleaning. In actual use, the nozzle channel can cooperate with an external air or liquid supply system, allowing liquid or gas to be transported through the nozzle channel to the nozzle and sprayed onto the pressure plate 31. During cleaning, liquid can be sprayed into the cleaning chamber through the nozzle via the liquid supply system to assist in cleaning the liquid and residue. Gas can also be sprayed onto the pressure plate 31 through the nozzle via the air supply system to remove residual moisture. Multiple nozzles can be provided, and fan-shaped water surface nozzles can be used to fully cover the upper surface of the pressure plate 31 during cleaning.

[0053] like Figure 1 As shown, in this embodiment, the sludge-liquid separator also includes a limiting component 50 and a positioning component 60. The limiting component 50 is movably positioned and can extend into the conveying path of the medicine tank 70. Thus, when the medicine tank 70 is conveyed to the intermediate conveyor line 22, it abuts against the limiting component 50, preventing further conveying and achieving initial positioning of the medicine tank 70. The positioning component 60 is also movably positioned and can abut against the medicine tank 70. Both the limiting component 50 and the positioning component 60 engage with different positions around the medicine tank 70, allowing the positioning component 60 to further adjust the position of the medicine tank 70 after initial positioning, achieving precise positioning.

[0054] like Figure 7 As shown, the limiting component 50 in this embodiment includes a limiting member 51 and a limiting drive member 52. The limiting member 51 is located on the intermediate conveyor line 22 near the discharge conveyor line 23. The limiting member 51 is movable and can move laterally or longitudinally. When the limiting member 51 extends, it can enter the conveying path of the medicine barrel 70, thereby obstructing the conveying of the medicine barrel 70. When the limiting member 51 retracts, it can exit the conveying path of the medicine barrel 70, thereby avoiding the conveying of the medicine barrel 70 and allowing the medicine barrel 70 to be conveyed onto the discharge conveyor line 23. The limiting drive member 52 can be a component such as a cylinder, which is drivenly connected to the limiting member 51 and drives the limiting member 51 to move, thereby obstructing or avoiding the conveying of the medicine barrel 70.

[0055] like Figure 6As shown, the positioning component 60 in this embodiment includes a positioning member 61 and a positioning drive member 62. The positioning member 61 has a positioning recess 611, the shape of which is adapted to the shape of the side of the medicine barrel 70. The positioning member 61 can be moved laterally, and the positioning member 61 and the limiting member 51 are located at different positions around the medicine barrel 70. The positioning drive member 62 can be a component such as a cylinder, which is driven to connect with the positioning member 61 and drives the positioning member 61 to move closer to or away from the medicine barrel 70 to position or avoid the medicine barrel 70. After the limiting member 50 is initially positioned, the positioning component 60 is activated, and the positioning drive member 62 drives the positioning member 61 to extend and move to position the medicine barrel 70. The positioning member 61 gradually moves closer to the medicine barrel 70, so that a part of the periphery of the medicine barrel 70 is located in the positioning recess 611. The shape of the positioning recess 611 and the pushing of the positioning member 61 move the medicine barrel 70 to a predetermined position, thereby ensuring the accuracy of the fit between the medicine barrel 70 and the pressing plate 31 and other components.

[0056] In this embodiment, the positioning component 61 uses a positioning plate, and multiple positioning plates are provided. This embodiment takes two as an example. The two positioning plates are stacked one on top of the other, and each positioning plate has a positioning recess 611 on the same side, thus forming a contoured double-plate design. This effectively prevents the cylindrical medicine barrel 70 from slipping due to compression, ensuring the safety of positioning. Furthermore, the number of positioning components 60 can be set as needed. For example, positioning components 60 can be provided on both opposite sides of the medicine barrel 70. In this way, the positioning components 60 on both sides can simultaneously push and clamp the medicine barrel 70, making the positioning of the medicine barrel 70 more accurate and reliable.

[0057] like Figure 2 As shown, the rack 10 in this embodiment adopts a cabinet structure, which serves as the main support and organically integrates various functional components. The relative dimensions ensure that each functional component can effectively perform its function. Of course, the rack 10 can also adopt a frame structure.

[0058] The overall working process of the sludge-liquid separator in this embodiment is as follows:

[0059] The feeding conveyor line 21 receives the medicine barrel 70 transferred from the previous process. At this time, the intermediate conveyor line 22 is in the conveying position. The medicine barrel 70 is fed into the intermediate conveyor line 22. When the intermediate conveyor line 22 transfers again, the limiting component 50 stops the medicine barrel 70 at a specific position on the intermediate conveyor line 22. The positioning components 60 on both sides push out to accurately position the medicine barrel 70. The extrusion device 30 drives the pressing plate 31 to descend through the cylinder to extrude the Chinese herbal medicine liquid in the medicine barrel 70 to separate the liquid from the residue. After the liquid is transferred to the packaging equipment, the pressing plate 31 moves up and away from the top of the medicine barrel 70. The limiting component 50 retracts, and the intermediate conveyor line 22 starts again to transfer the medicine barrel 70 along with the residue inside to the discharge conveyor line 23. The discharge conveyor line 23 transfers the medicine barrel 70 to the next process. Once the medicine tank 70 is detached from the intermediate conveyor line 22, the intermediate conveyor line 22 moves to the cleaning position. The cleaning tank 41 of the cleaning device 40 moves upward and begins to inject water into the cleaning tank 41. At the same time, the pressing plate 31 of the squeezing device 30 moves downward and enters the cleaning tank 41. After the cover 33 closes with the cleaning tank 41, the spray nozzles in the cleaning tank 41 and the nozzles on the cover 33 spray clean water to clean the pressing plate 31, removing residual medicine and attached medicine residue from the pressing plate 31. After cleaning is completed, the pressing plate 31 moves upward, the cleaning tank 41 moves downward and discharges wastewater. The intermediate conveyor line 22 returns to the conveying position, waiting for the next medicine tank 70 to enter for medicine separation.

[0060] Example 2

[0061] The difference from Embodiment 1 is that the intermediate conveyor line 22 does not adopt a laterally movable configuration.

[0062] In this embodiment, the intermediate conveyor line 22 does not have an avoidance position. A channel can be reserved in the middle of the intermediate conveyor line 22. For example, the intermediate conveyor line 22 can be in the form of a conveyor belt, and the area between the two conveyor belts is the channel. In this way, the channel allows the extrusion end to descend into the cleaning device 40 even when the intermediate conveyor line 22 is not moving, thereby achieving cleaning of the extrusion end. In addition to the above form, other forms of channels can also be used. For example, if the intermediate conveyor line 22 uses conveyor rollers, the gap between the conveyor rollers can be increased to form a channel. It should be noted that in the above method, the medicine barrel 70 needs to be conveyed away from directly below the extrusion end before cleaning can be performed.

[0063] Of course, in addition to the channel setting method, other forms can also be used to achieve cleaning of the extrusion end. For example, the cleaning device 40 is not set directly below the middle conveyor line 22, but is set at the lower side. Similarly, the extrusion end can move horizontally in addition to moving up and down, so that the extrusion end can move from directly above the middle conveyor line 22 to directly above the cleaning device 40, thereby achieving the cleaning action.

[0064] It should be noted that "multiple" in the above embodiments refers to at least two.

[0065] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0066] 1. This solves the problem that existing Chinese medicine decoction equipment cannot meet the requirements of traditional decoction separation and extraction of medicinal liquid;
