Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine extraction equipment technology, specifically a horizontal rotary extraction tank that facilitates material feeding and discharging. Background Technology

[0002] In the large-scale extraction of traditional Chinese medicine, multi-functional extraction tanks are widely used. However, the heat medium channels of traditional multi-functional extraction tanks are all located outside the tank body. Heat needs to be conducted to the solvent and materials inside the tank through the tank wall, which results in large heat loss and uneven temperature conduction. This leads to prolonged extraction time, increased energy consumption, uneven temperature at different points inside the tank, and is prone to causing local overheating of materials or insufficient extraction.

[0003] A Chinese invention patent (publication number CN109055193B) discloses an inclined drum-type vacuum solid fermentation tank with built-in heat-exchangeable spiral blades. This fermentation tank has the same purpose as the traditional Chinese medicine extraction tank, which requires heating the material inside the tank and ensuring that the tank is in a certain vacuum state. This device makes the spiral blades inside the tank hollow, and injects heat exchange medium into the spiral blades through the water inlet. Combined with the rotation of the tank itself, the tank heats the material faster and more evenly.

[0004] During the heating process described above, the tank needs to rotate along its own axis. Therefore, the device is equipped with a heat exchange medium rotary joint at the end of the tank to ensure that the inlet and outlet pipes do not rotate with the tank. At the same time, since the fermentation tank needs to be kept in a vacuum state during operation, the device is equipped with a vacuum rotary joint at the top of the tank to ensure that the rotation of the tank does not cause the vacuum pipe to rotate with it.

[0005] The above setup results in both ends of the tank being occupied, preventing material from being poured out from the ends of the tank. The device fixes the discharge port on the side wall of the tank, but due to the obstruction of the spiral blades, the material cannot be directly discharged through the discharge port under gravity. Therefore, the material needs to be sent out by the continuous reversal of the tank and the spiral blades.

[0006] However, the discharge structure of this fermenter has defects. Because the discharge port and the tank body rotate continuously and synchronously, the material around the discharge port can only be discharged under gravity when the discharge port rotates to the bottom of the tank body. But at this time, the material inside the tank cannot be sent out. The tank body needs to continue to rotate and be pushed by the spiral blades to send some material to the vicinity of the discharge port. At this time, the discharge port cannot be guaranteed to be facing downwards, so continuous discharge cannot be achieved. Moreover, this discharge structure cannot separate the solid residue and liquid solvent inside the tank body, and cannot discharge the liquid solvent separately. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the main objective of this invention is to provide a horizontal rotary extraction tank that facilitates material loading and unloading, thereby solving the problem that existing rotary extraction tanks are not convenient for loading and unloading materials.

[0012] As a further improvement of the present invention, an electric heating plate is fixedly installed inside the tank, and an electric sliding rail electrically connected to the electric heating plate is fixedly installed at the end of the tank.

A first cleaning nozzle is fixedly connected to one end of the cleaning pipe that connects to the inside of the tank, and the rotary joint is fixedly connected to one end of the cleaning pipe that connects to the bottom of the tank. The rotary joint can also be detachably connected to an external high-pressure water pipe. A second cleaning nozzle that connects to the inside and outside is fixedly installed on the side wall of the cover fixing component. The second cleaning nozzle can be detachably connected to an external high-pressure water pipe. Check valves are installed at the rear ends of the first cleaning nozzle and the second cleaning nozzle.

[0017] As a further improvement of the present invention, a backflush nozzle communicating with the inside and outside of the rotating part of the cover is fixedly provided on the rotating part of the cover.

[0018] The beneficial effects of this invention are reflected in: This device addresses the problems of existing rotary extraction tanks where rotating joints occupy both ends of the tank, leading to difficulties in feeding and discharging materials, inability to continuously discharge materials, and failure to separate liquid and sludge. By designing a rotary sealing structure for the tank cover assembly, the rotating part of the cover rotates synchronously with the tank body and can achieve liquid-sludge separation through the built-in filter screen. The fixed part of the cover remains stationary and can continuously discharge the solvent through the centrally penetrating discharge pipe. This allows the solvent to flow out continuously and stably under the action of gravity, unaffected by the rotation of the tank body. The sludge, after being intercepted by the filter screen, can be pushed out by the hollow blades through the reverse rotation of the tank body, thus achieving the separation and thorough discharge of liquid solvent and solid sludge.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 In this embodiment, see Figure 1-10 The present invention provides a horizontal rotary extraction tank for convenient feeding and discharging, comprising: a heating assembly and a tank lid assembly; The heating assembly includes a tilting part 1 fixedly connected to an external base and a mounting frame 2 rotatably mounted on the tilting part 1; a tank 3 is rotatably mounted on the mounting frame 2; the inner wall of the tank 3 is provided with a heating and stirring part 4 for stirring and mixing, and a rotary joint 12 is connected to the end of the heating and stirring part 4; a heat exchange medium flows inside the heating and stirring part 4; the tank 3 rotates along its axis under the action of external force, thereby driving the heating and stirring part 4 to rotate to stir and heat the material inside the tank; The can lid assembly includes: a hinged door support 5 rotatably mounted on a mounting bracket 2; a lid fixing member 6 flexibly connected to the hinged door support 5 via a support spring 501; a lid rotating member 7 coaxially rotatably connected to the lid fixing member 6; a lid bearing 8 assembled between the lid fixing member 6 and the lid rotating member 7 to ensure smooth relative rotation; the lid rotating member 7 is connected to the can opening of the can body 3; the central axis of the lid rotating member 7 communicates with the interior of the can body 3; and the central axes of the lid rotating member 7 and the lid fixing member 6 are located at... The cover fixing component 6 is connected to a vacuum pump port 601 on its side wall, and a discharge pipe 602 is connected to the end of the cover fixing component 6. A valve 603 is installed inside the discharge pipe 602. A filter screen 701 is fixedly installed inside the cover rotating component 7. A pneumatic lock 702 is rotatably installed on the outside of the cover rotating component 7. The pneumatic lock 702 is used to seal the cover rotating component 7 at the mouth of the tank body 3. A tank mouth sealing ring 703 is fixedly installed on the cover rotating component 7 at the mouth of the tank body 3. The rotating part 7 of the cover has a rotating air passage 9 connected to the pneumatic latch 702 on its side, and the fixing part 6 of the cover has a fixing air passage 10 connected to the external air compressor on its side. The rotating air passage 9 and the fixing air passage 10 are rotatably connected. A rotating sealing ring 11 is provided between the rotating part 7 of the cover and the fixing part 6 of the cover. The rotating sealing ring 11 is used to ensure that gas will not leak from the rotation gap between the two when the rotating part 7 of the cover and the fixing part 6 of the cover rotate relative to each other.

[0023] Preferably, the tank body 3 adopts an integrated structure of an elliptical head bottom, a cylindrical middle section, and a conical front end; a rolling ring is provided at the front end of the tank body 3 to cooperate with the supporting rollers on the mounting frame 2; and the outside of the tank body 3 is covered with a heat insulation layer 306.

[0024] Preferably, the valve 603 is a pneumatic butterfly valve.

[0025] In the above configuration, by setting valve 603, the discharge flow rate can be controlled when discharging liquid solvent separately, preventing the solvent from splashing due to excessive flow rate.

[0026] Preferably, the filter 701 is a stainless steel filter 701, and the pore size of the stainless steel filter 701 is 50-100 mesh to meet the requirements of traditional Chinese medicine extraction.

[0027] Preferably, there are 4 to 8 pneumatic locking buckles 702 to ensure that the vacuum inside the tank does not leak.

[0028] In the above configuration, when the cover rotating component 7 is attached to the mouth of the can 3, the moving end of the pneumatic latch 702 extends under the action of external force, locking the can 3 and the cover rotating component 7 to achieve the effect of sealing the mouth of the can. Conversely, the can 3 and the cover are unlocked. During the extraction process, the pneumatic latch 702 can continuously obtain stable compressed air through the rotating air passage 9 and the fixed air passage 10, ensuring that the pneumatic latch 702 always remains locked during the rotation of the can 3, and avoiding sealing failure due to pressure fluctuations.

[0029] In the above setup, under the action of external force, the tilting part 1 controls the mounting bracket 2 to tilt the tank body 3 backward, thereby adjusting the tank opening to a high position; after the solvent and medicine are placed inside the tank body 3, under the action of external force, the hinge door support 5 is rotated, thereby causing the cover rotating part 7 to fit and seal at the tank opening of the tank body 3, while simultaneously closing the valve 603; an external air compressor is used to control the pneumatic lock 702 through the fixed air passage 10 and the rotating air passage 9, so that the cover rotating part 7 is sealed at the tank opening; an external vacuum pump is used to perform vacuuming treatment inside the tank through the vacuum pipe port 601; Then, under the action of external force, the tank 3 rotates along its own axis and heat exchange medium is introduced into the heating and stirring section 4 through the rotary joint 12 to carry out the extraction work; After extraction, under the action of external force, the tilting part 1 controls the tank body 3 to tilt forward to adjust the tank opening to a low position and open the valve 603. At this time, under the action of gravity, the solvent flows out from the discharge liquid pipe 602 through the filter screen 701, and the residue is blocked by the filter screen 701. After the solvent has finished flowing, the pneumatic lock 702 is unlocked and the hinge door support 5 is rotated to separate the cover rotating part 7 from the tank opening. Then, the tank body 3 is rotated in the opposite direction to rotate and discharge the residue under the drive of the heating and stirring part 4.

[0030] Furthermore, the tilting part 1 includes a base frame 101 rotatably connected to the mounting frame 2. The base frame 101 is fixedly mounted on the external base. A tilting drive component 102 is rotatably connected to the base frame 101, and the moving end of the tilting drive component 102 is rotatably connected to the mounting frame 2.

[0031] Preferably, the tilting drive 102 is a linear hydraulic rod.

[0032] Preferably, the top of the base frame 101 is rotatably mounted with four bearing rollers to cooperate with the arc support slide rail at the bottom of the mounting frame 2 to support the overall weight of the mounting frame 2 and the extraction tank, and to allow the mounting frame 2 to tilt relative to the base frame 101.

[0033] Preferably, the tilting angle of the tank 3 is in the range of -25° to 25°, and the hydraulic drive adjustment speed is 5° / min.

[0034] In the above configuration, the moving end of the tilting drive 102 extends or shortens under the action of external force, thereby controlling the tank 3 to tilt forward or backward under the drive of the mounting bracket 2.

[0035] Furthermore, a rotation drive component 201 is fixedly installed on the mounting bracket 2, and a rotation follower component 202 is coaxially and fixedly connected to the end of the tank body 3. The rotation drive component 201 and the rotation follower component 202 are linked together through a transmission component 203. The rotation drive component 201 rotates under the action of external force, and drives the rotation follower component 202 to rotate under the linkage of the transmission component 203, thereby causing the tank body 3 to rotate along its own axis.

[0036] Preferably, the rotation drive 201 is a motor connected to a belt drive pulley, the rotation driven 202 is a belt driven pulley, and the transmission 203 is a belt.

[0037] Furthermore, the heating and stirring part 4 includes: two hollow blades 401 fixedly disposed inside the tank body 3 and spiral in the same direction; an outer conduit 402 connected to the two hollow blades 401 fixedly disposed outside the tank body 3; and two superheated pipes 403 fixedly disposed at the tail ends of the two hollow blades 401 respectively.

[0038] In the above configuration, the heat exchange medium enters the interior of a hollow blade 401 from a superheated pipe 403 under the action of external force. Then, the heat exchange medium flows from the hollow blade 401 into another hollow blade 401 through the outer conduit 402. Finally, the heat exchange medium flows out from another superheated pipe 403, so as to realize the continuous flow of the heat exchange medium inside the tank 3 and transfer heat to the solvent.

[0039] Preferably, the heat exchange medium includes hot water, steam, heat transfer oil, etc.

[0040] The spiral hollow blades 401 in the above configuration have the following three functions: 1. When the tank 3 rotates forward, the hollow blades 401 play a stirring role; 2. When the tank 3 rotates in reverse, the hollow blades 401 push the material outward to play a slag removal role; 3. When the heat exchange medium flows in the internal channel of the hollow blades 401, it has a heat exchange function to ensure that the solvent is heated and extracted evenly.

[0041] Furthermore, an electric heating plate 301 is fixedly installed inside the tank body 3, and an electric sliding rail 302 electrically connected to the electric heating plate 301 is fixedly installed at the end of the tank body 3. The electric sliding rail 302 is used to supply power to the electric heating plate 301 when the tank body 3 rotates.

[0042] In the above setup, depending on the different extraction processes of various drugs, an electric heating plate 301 can also be installed on the inner wall of the tank 3 to realize a dual-mode heating mode that combines fluid heating and electric heating, adapting to the temperature requirements of different materials.

[0043] Furthermore, a door closing cylinder 204 is rotatably connected to the mounting bracket 2, and the moving end of the door closing cylinder 204 is rotatably connected to the hinge door support 5.

[0044] In the above configuration, the moving end of the door-closing cylinder 204 extends under the action of external force, thereby pushing the can body 3 bracket to rotate relative to the mounting bracket 2, thereby causing the cover rotating part 7 to fit against the can opening of the can body 3; conversely, the cover rotating part 7 moves away from the can opening of the can body 3.

[0045] Example 2 In this embodiment, due to the structural limitation of the tilt angle of the tank body 3, it is impossible to invert the tank opening vertically downwards, resulting in the inability to completely empty the liquid inside the tank. As a result, the total amount of liquid extracted by the extraction tank in a single extraction during the production process will decrease, affecting the production efficiency of the extraction tank.

[0046] To address the aforementioned issues, the rotating cover component 7 further comprises: an end cap 704 and a connecting ring 705 coaxially fixed to the front end of the end cap 704; the connecting ring 705 is coaxially rotatably connected to the cover fixing component 6; the rotating air passage 9 is provided on the periphery of the connecting ring 705 and the cover bearing 8 is installed thereon; a water-scooping plate 706 is fixedly disposed inside the end cap 704, the water-scooping plate 706 having a spoon-shaped structure arranged in a circumferential array; and a spiral blade-shaped anti-backflow component 707 is coaxially fixed inside the connecting ring 705.

[0047] In the above configuration, the water-scooping plate 706 rotates under the action of external force, thereby collecting the liquid located at the bottom of the tank opening into the water-scooping plate 706. When the water-scooping plate 706 continues to rotate upward to the top, the liquid flows out from the water-scooping plate 706 under the action of gravity and falls into the gap of the spiral blade of the anti-backflow component 707 of the connecting ring 705. The spiral blade can prevent the liquid from flowing back from the connecting ring 705 into the tank 3 under the action of inertial flow. At the same time, the rotation of the spiral blade under the action of external force can continuously push the liquid outward, thereby reducing the liquid residue in the tank.

[0048] Example 3 In this embodiment, since the tank 3 needs to rotate at an inclined angle, the traditional method is to install a bearing coaxially at the end of the tank 3 and directly fit the bearing onto the mounting bracket 2. However, due to the inevitable influence of machining errors, assembly errors, load deformation and temperature changes on the mechanical device, there are axial, radial and angular offsets between the tank 3 and the mounting bracket 2, which causes the bearing to jam, which not only generates noise but also shortens the bearing life.

[0049] To further address the aforementioned issues, a hollow tank bottom support shaft 303 is coaxially and fixedly connected to the end of the tank body 3. The superheating pipe 403 is installed inside the tank bottom support shaft 303, and the superheating pipe 403 is connected to a rotary joint 12 fixedly installed at the end of the tank bottom support shaft 303. A universal support part 13 is rotatably connected to the outside of the tank bottom support shaft 303. The universal support part 13 includes: left and right supports 1301 fixedly installed on the mounting frame 2, and an outer support ring 1302 rotatably connected to the left and right supports 1301 in the horizontal radial direction. The outer support ring 1302 is connected to the left and right supports 1301 via left and right rotating shafts 1303. The outer support ring 1302 provides the tank body 3 with the freedom to rotate up and down. The inner support ring 1304 is rotatably connected to the vertical diameter inside the outer support ring 1302. The inner support ring 1304 is connected to the outer support ring 1302 via up and down rotating shafts 1305. The inner support ring 1304 provides the tank body 3 with the freedom to rotate left and right. The inner support ring 1304 is rotatably connected to the tank bottom support shaft 303. A support bearing 1306 is provided between the inner support ring 1304 and the tank bottom support shaft 303.

[0050] In the above configuration, the universal support 13 provides the tank 3 with the freedom to rotate left and right and up and down while ensuring that the tank 3 can rotate normally along its own axis. This automatically compensates for the processing error, assembly error, load deformation and deformation caused by temperature changes between the tank 3 and the mounting frame 2.

[0051] Example 4 In this embodiment, since mixing different traditional Chinese medicines may lead to the cancellation of their medicinal properties, and an extraction tank produces more than one product, the extraction tank needs to be thoroughly cleaned when changing the extraction product. After extraction, residues of medicinal materials and solvents are easily left on the inner wall of the tank body 3, the hollow blades 401, and the sealing surface of the tank opening. Existing equipment's rinsing devices mostly use fixed nozzles, and the tank body 3 is stationary and structurally limited, resulting in cleaning dead zones. The residual substances pose a risk of cross-contamination, affecting the purity of subsequent batches of extracted products. To further address the aforementioned technical issues, a cleaning pipe 304 is fixedly installed inside the side wall of the tank body 3. A first cleaning nozzle 305 is fixedly connected to one end of the cleaning pipe 304 that connects to the inside of the tank body 3, and the rotary joint 12 is fixedly connected to the other end of the cleaning pipe 304 that connects to the bottom of the tank body 3. The rotary joint 12 can also be detachably connected to an external high-pressure water pipe. A second cleaning nozzle 604, connecting the inside and outside, is fixedly installed on the side wall of the cover fixing member 6. The second cleaning nozzle 604 can be detachably connected to an external high-pressure water pipe. Check valves are fitted at the rear ends of the first cleaning nozzle 305 and the second cleaning nozzle 604.

[0052] Preferably, the first cleaning nozzle 305 and the second cleaning nozzle 604 are high-pressure nozzles.

[0053] Preferably, the first cleaning nozzle 305 and the second cleaning nozzle 604 are equipped with check valves at their rear ends to ensure that the vacuum inside the tank will not leak during extraction and that the liquid solvent will not flow out through the cleaning nozzles during the extraction of the medicine.

[0054] Preferably, 3 to 4 first cleaning nozzles 305 are evenly arranged inside the tank body 3. The first cleaning nozzles 305 form an angle of 15° to 45° with the inner wall of the tank body 3, and the first cleaning nozzles 305 can perform rinsing while the tank body 3 rotates.

[0055] In the above setup, when it is necessary to clean the tank 3, agitator, and cover, the first cleaning nozzle 305 and the second cleaning nozzle 604 are connected to an external high-pressure water pipe. The high-pressure water pipe is turned on, and the tank 3 is controlled to rotate at a low speed. The nozzle sprays high-pressure clean water (or special cleaning fluid) to fully rinse the inner wall of the tank 3, the hollow blades 401, and the inside of the tank cover assembly.

[0056] Example 5 In this embodiment, because the size of the drug residue varies, the drug residue will move towards the filter screen 701 under the action of gravity during the process of draining the liquid solvent, and accumulate at the filter screen 701, which will lead to poor drainage of the liquid solvent.

[0057] To solve the above-mentioned technical problems, further, a back-blowing nozzle 14 is fixedly provided on the rotating cover 7, which is connected to the inside and outside of the rotating cover 7. A three-way solenoid valve 15 is fixedly connected to one end of the back-blowing nozzle 14, and the other two ends of the three-way solenoid valve 15 are fixedly connected to the rotating air passage 9 and the pneumatic lock 702, respectively.
