Description

Technical Field

[0001] The invention relates to the field of traditional Chinese medicine processing, and in particular to a traditional Chinese medicine liquid filtering device. Background Art

[0002] In the production process of traditional Chinese medicine, the filtration of traditional Chinese medicine liquid is very important, and its effect directly affects product quality and production efficiency. However, traditional traditional Chinese medicine liquid filtration devices have exposed many drawbacks in practical applications.

[0003] Traditional filtration devices have a single power mode, mostly relying on gravity sedimentation or simple pressure difference to separate the solid and liquid components in traditional Chinese medicine liquid. This method is barely usable when processing small batches of traditional Chinese medicine liquid; once faced with massive amounts of liquid medicine in large-scale production, it becomes inefficient. The filtration process is extremely slow, and a lot of time is spent waiting, which seriously restricts production efficiency and greatly increases the cost of the production cycle.

[0004] The characteristics of different Chinese medicines vary greatly. Some Chinese medicines contain viscous components such as polysaccharides and mucus. In low temperature environments, the viscous substances tend to accumulate and solidify on the filter, blocking the pores of the filter, causing the filtration efficiency to drop sharply. Traditional devices lack functions such as temperature regulation, making it difficult to cope with such special situations, and their scope of application is limited.

[0005] Filter cleaning has always been a problem for traditional devices. The traditional cleaning method is to simply flush the surface of the filter with water, which cannot effectively remove impurities and sticky substances that penetrate deep into the pores. Over time, the pores of the filter are filled with impurities, and the filtering performance declines sharply. In order to ensure the filtering effect, the filter needs to be replaced frequently, which not only wastes filter materials and increases costs, but the cumbersome operation of replacing the filter will also slow down production progress.

[0006] In terms of waste liquid treatment, the waste liquid after cleaning the filter screen of traditional devices is often discharged directly without treatment, and the residual Chinese medicine components in it will pollute the surrounding water bodies, soil and other ecological environments. In addition, the impurities remaining in the reaction cylinder are difficult to completely remove and will mix into the subsequent Chinese medicine liquid, affecting the purity and quality stability of the product.

[0007] In addition, the traditional device has a low degree of automation in filter switching and maintenance, and relies on manual operation. This not only requires operators to have high skills and concentration, but also has a high probability of manual errors. Improper operation can easily affect the filtering effect and even damage the equipment. At the same time, manual operation means high cost investment, which increases the burden on Chinese medicine manufacturers.

[0008] In summary, the research and development of new Chinese medicine liquid filtration devices that can solve the above-mentioned problems is very necessary to promote the efficient and sustainable development of the Chinese medicine production industry. Summary of the invention

[0043] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0044] Refer to Figures 1 to 10 , a traditional Chinese medicine liquid filtering device, comprising:

[0045] A reaction cylinder 1, at the lower end of the reaction cylinder 1, a plurality of positioning holes 2 are formed at equal angles along the circumferential direction (as Figure 3 shown), and at the upper end of the reaction cylinder 1, a plurality of cleaning sandwich layers 11 are formed at equal angles along the circumferential direction;

[0046] A centrifugal mechanism 12 (as Figure 6 shown), arranged at the lower part of the reaction cylinder 1, including an arc-shaped plate 13 rotatably connected coaxially with the lower end of the reaction cylinder 1;

[0047] A plurality of filter screens 20, respectively fixedly connected to the plurality of positioning holes 2;

[0048] A plurality of flow guiding mechanisms 21, corresponding to the plurality of cleaning sandwich layers 11 one by one, each flow guiding mechanism 21 respectively includes a liquid baffle 25, a rotating brush 31 and a rubber scraper 41, the liquid baffle 25 is arranged on the side of the filter screen 20 close to the axis of the reaction cylinder 1, the rubber scraper 41 is arranged on the side of the liquid baffle 25 close to the filter screen 20, and the rotating brush 31 is arranged on the side of the filter screen 20 far from the axis of the reaction cylinder 1;

[0049] A plurality of drainage covers 44, respectively arranged outside the plurality of filter screens 20 and fixedly connected to the outer wall of the reaction cylinder 1.

[0050] When the device is in operation, the operator pours the traditional Chinese medicine liquid to be filtered into the reaction cylinder 1. Subsequently, the traditional Chinese medicine liquid will fall into the arc-shaped plate 13. Then, when the arc-shaped plate 13 rotates (the specific rotation process will be explained later), the traditional Chinese medicine liquid will flow away from the axis of the reaction cylinder 1 under the action of centrifugal force until the traditional Chinese medicine liquid contacts the corresponding filter screen 20. Subsequently, after passing through the filter screen 20, the traditional Chinese medicine liquid is guided to the collection tank through the corresponding drainage cover 44.

[0051] During this process, several filter screens 20 are alternately connected to the inside of the reaction cylinder 1. That is, during the filtration of the traditional Chinese medicine liquid, one of the two adjacent filter screens 20 is blocked by the corresponding liquid blocking plate 25. The inner side of the blocked filter screen 20 is cleaned by the rubber scraping plate 41, and the outer side is cleaned by the rolling brush 31 to prevent impurities or fructose in the traditional Chinese medicine liquid from adhering to the inner and outer sides of the filter screen 20 and affecting the filtering function of the filter screen 20.

[0052] In order to drive the arc-shaped plate 13 to rotate, the following features are specifically set:

[0053] The centrifugal mechanism 12 further includes a driving motor 14, a driving gear 15, a driving gear ring 16 and an adapter plate 17. The driving motor 14 is fixedly arranged below the reaction cylinder 1. The driving gear 15 is coaxially fixedly connected to the output end of the driving motor 14. The adapter plate 17 is rotatably arranged coaxially at the lower end of the reaction cylinder 1. The upper end of the adapter plate 17 is fixedly connected to the arc-shaped plate 13, and the lower end is fixedly connected to the driving gear ring 16. The driving gear ring 16 meshes with the driving gear 15. After the driving motor 14 is started, its output end drives the driving gear 15 to rotate. The driving gear 15 meshes with the driving gear ring 16, thereby driving the adapter plate 17 to rotate around the axis at the lower end of the reaction cylinder 1. Since the upper end of the adapter plate 17 is fixedly connected to the arc-shaped plate 13, the arc-shaped plate 13 also rotates synchronously, providing power for the filtration of the traditional Chinese medicine liquid under the action of centrifugal force.

[0054] In order to adapt to the filtration of different types of traditional Chinese medicine liquids and ensure that the device can also heat the traditional Chinese medicine liquid, thereby expanding the application range of the device, the following features are specifically set:

[0055] The centrifugal mechanism 12 further includes a heater 18 and a heat conduction tube 19. The heater 18 is fixedly arranged beside the driving motor 14. The heat conduction tube 19 is arranged at the lower end of the arc-shaped plate 13 and is coaxially fixedly connected to the output end of the heater 18. When filtering the traditional Chinese medicine liquid that needs to be heated, the heater 18 is turned on. The heat generated by the heater 18 is transmitted to the arc-shaped plate 13 through the heat conduction tube 19. After the arc-shaped plate 13 is heated, it can heat the traditional Chinese medicine liquid located on it, thereby increasing the temperature of the traditional Chinese medicine liquid, meeting the filtration requirements of different types of traditional Chinese medicine liquids, and expanding the application range of the device.

[0056] In order to drive the liquid baffle 25 to move and ensure that a number of filter screens 20 can be sequentially communicated with the inside of the reaction cylinder 1, the following features are specifically provided:

[0057] The diversion mechanism 21 further includes a cylinder 22, a lifting rod 23 and two limiting rods 24. The cylinder 22 is fixedly arranged at the upper end of the reaction cylinder 1. The two limiting rods 24 are respectively arranged on both sides of the liquid baffle 25. The two ends of the limiting rod 24 are fixedly connected to the inner wall of the reaction cylinder 1. The upper end of the lifting rod 23 is fixedly connected to the output end of the cylinder 22, and the lower end is fixedly connected to the upper end of the liquid baffle 25. When it is necessary to switch the communication state between the filter screen 20 and the inside of the reaction cylinder 1, the cylinder 22 is started. The output end of the cylinder 22 extends or retracts, driving the lifting rod 23 to move up and down. The lifting rod 23 then pushes the liquid baffle 25 to move up and down along the direction defined by the limiting rod 24, realizing the blocking or release of the filter screen 20, so that a number of filter screens 20 can be sequentially communicated with the inside of the reaction cylinder 1 and perform the filtering operation orderly.

[0058] In order to drive the rubber squeegee 41 to perform reciprocating movement in the vertical direction and ensure that the rubber squeegee 41 can clean the inner side of the filter screen 20 during the movement, the following features are specifically provided:

[0059] The diversion mechanism 21 further includes a power motor 36, a power gear 37, a reciprocating gear 38, a reciprocating nut 39, a reciprocating screw 40 and an extrusion guide plate 43. The power motor 36 is fixedly connected to the upper end of the reaction cylinder 1 (refer to Figure 7 ), the power gear 37 is coaxially fixedly connected to the output end of the power motor 36. The reciprocating gear 38 is rotatably connected to the upper end of the reaction cylinder 1 and meshes with the power gear 37. The reciprocating nut 39 is coaxially fixedly connected to the reciprocating gear 38. The reciprocating screw 40 is threadedly connected to the reciprocating nut 39. The extrusion guide plate 43 is slidably connected to the cleaning sandwich layer 11 (refer to Figure 8 ), the lower end of the extrusion guide plate 43 is fixedly connected to the upper end of the rubber squeegee 41, and the upper end of the extrusion guide plate 43 is fixedly connected to the lower end of the reciprocating screw 40. After the power motor 36 is started, the output end of the power motor 36 drives the power gear 37 to rotate. The power gear 37 drives the reciprocating gear 38 to rotate. The reciprocating gear 38 drives the coaxial reciprocating nut 39 to rotate. Since the reciprocating screw 40 is threadedly connected to the reciprocating nut 39 and the extrusion guide plate 43 restricts the rotation of the reciprocating screw 40, the reciprocating screw 40 performs reciprocating movement in the vertical direction under the action of the reciprocating nut 39, and then drives the extrusion guide plate 43 and the rubber squeegee 41 connected thereto to perform reciprocating movement in the vertical direction, realizing the cleaning of the inner side of the filter screen 20.

[0060] In order to supply distilled water to the filter screen 20 during the movement of the rubber squeegee 41, thereby improving the cleaning effect of the filter screen 20, the following features are specifically provided:

[0061] A liquid cylinder 26 is coaxially and fixedly connected to the upper part of the reaction cylinder 1. The diversion mechanism 21 further includes a main pump 27 and a conduit 28. The main pump 27 is arranged at the lower end of the liquid cylinder 26 and its input end is communicated with the liquid cylinder 26. One end of the conduit 28 is communicated with the output end of the main pump 27, and the other end is communicated with the cleaning interlayer 11. During the process of the rubber squeegee 41 cleaning the filter screen 20, the main pump 27 is started. The main pump 27 pumps out the distilled water in the liquid cylinder 26 and transports it to the cleaning interlayer 11 through the conduit 28. The distilled water flows out from the cleaning interlayer 11. When the rubber squeegee 41 moves, distilled water is provided to the filter screen 20, enhancing the cleaning effect of the filter screen 20 and effectively removing the impurities attached to the filter screen 20.

[0062] In order to ensure that the distilled water in the liquid cylinder 26 can fall during the reciprocating movement of the rubber squeegee 41, and at the same time facilitate the cleaning of the filter screen 20, the following features are specifically set:

[0063] A number of limiting grooves 42 are formed at equal intervals on the side of the rubber squeegee 41 close to the filter screen 20 (refer to Figure 9 ). During the movement of the rubber squeegee 41, the limiting grooves 42 can store a certain amount of distilled water. As the rubber squeegee 41 moves, this distilled water is evenly released onto the filter screen 20, not only ensuring that all parts of the filter screen 20 can be fully cleaned, but also making the distilled water more uniform, improving the cleaning effect, and at the same time helping to reduce the waste of distilled water.

[0064] In order to quickly discharge the cleaning liquid and facilitate the removal of the impurities remaining inside the reaction cylinder 1, the following features are specifically set:

[0065] A liquid guiding groove 10 is formed at the lower end of each positioning hole 2 (refer to Figure 3 ). The diversion mechanism 21 further includes a liquid discharge plate 3, a jacking push plate 5, two pneumatic push rods 4 and two jacking shafts 6. The liquid discharge plate 3 is slidably connected to the upper end of the liquid guiding groove 10 (refer to Figure 4 and Figure 5 ). The upper ends of the two jacking shafts 6 are fixedly connected to the lower end of the liquid discharge plate 3 respectively, and the lower ends of the two jacking shafts 6 are fixedly connected to the upper end of the jacking push plate 5 respectively. The two pneumatic push rods 4 are respectively arranged at the lower end of the jacking push plate 5 and their output ends are fixedly connected to the jacking push plate 5. When it is necessary to discharge the cleaning liquid and remove the impurities remaining in the reaction cylinder 1, the two pneumatic push rods 4 are started, and their output ends push the jacking push plate 5 to move upward. The jacking push plate 5 drives the liquid discharge plate 3 to move upward through the jacking shafts 6, opening the liquid guiding groove 10, so that the cleaning liquid and impurities can smoothly pass through the liquid guiding groove 10 and be discharged, realizing the rapid discharge of the cleaning liquid and the effective removal of the impurities remaining in the reaction cylinder 1.

[0066] In order to facilitate the centralized treatment of the waste liquid flowing into the liquid guiding groove 10, the following features are specifically set:

[0067] A liquid collecting bucket 9 is coaxially and fixedly connected to the lower part of the reaction cylinder 1. The diversion mechanism 21 further includes a liquid guide pipe 7 and a sub-pump 8. The sub-pump 8 is arranged on one side of the liquid guide groove 10 close to the liquid collecting bucket 9. One end of the liquid guide pipe 7 is communicated with the liquid guide groove 10, and the other end is communicated with the input end of the sub-pump 8. The output end of the sub-pump 8 is communicated with the liquid collecting bucket 9. After the cleaning liquid and impurities are discharged through the liquid guide groove 10, the sub-pump 8 is started. The sub-pump 8 sucks the waste liquid in the liquid guide groove 10 through the liquid guide pipe 7 and transports it to the liquid collecting bucket 9, realizing the centralized collection and treatment of the waste liquid, facilitating the subsequent unified disposal of the waste liquid, and avoiding environmental pollution caused by the random discharge of the waste liquid.

[0068] In order to facilitate the rotation of the rotary brush 31 while moving along the side of the filter screen 20 away from the axis of the reaction cylinder 1, the following features are specifically set:

[0069] An annular guide rail 34 is coaxially and fixedly connected to the lower part of the liquid cylinder 26. The lower end of the annular guide rail 34 is coaxially and fixedly connected with an annular gear ring 30 (as Figure 5 shown). The diversion mechanism 21 further includes a driving motor 29, a limiting gear 33, a brush holder 32 and a limiting claw 35. The limiting claw 35 is slidably connected to the annular guide rail 34 (as Figure 4 shown). The limiting claw 35 is fixedly connected to the brush holder 32. The brush holder 32 is rotatably connected to both ends of the rotary brush 31. The limiting gear 33 (as Figure 9 shown) is rotatably connected to the upper end of the limiting claw 35 and also meshes with the annular gear ring 30. The driving motor 29 is fixedly connected to the upper end of the limiting claw 35 and the output end is coaxially and fixedly connected to the limiting gear 33. When cleaning the outside of the filter screen 20, the driving motor 29 is started. The output end of the driving motor 29 drives the limiting gear 33 to rotate. The limiting gear 33 meshes with the annular gear ring 30. Since the limiting claw 35 is connected to the brush holder 32 and slides on the annular guide rail 34, the limiting claw 35 makes a circular motion along the annular guide rail 34 driven by the limiting gear 33. At the same time, the driving motor 29 also drives the rotary brush 31 to rotate, so that the rotary brush 31 rotates while moving along the side of the filter screen 20 away from the axis of the reaction cylinder 1, thereby comprehensively and efficiently cleaning the outside of the filter screen 20.

[0070] The working principle of this device is as follows. When the device is working, the operator first pours the traditional Chinese medicine liquid to be filtered into the reaction cylinder 1. Start the driving motor 14, which drives the driving gear 15 to rotate. The driving gear 15 meshes with the driving gear ring 16, causing the connecting disk 17 and the arc-shaped disk 13 connected thereto to rotate. Under the action of the centrifugal force generated by the rotation of the arc-shaped disk 13, the traditional Chinese medicine liquid flows in a direction away from the axis of the reaction cylinder 1, contacts the filter screen 20, and the filtered liquid flows into the collection tank through the drainage cover 44. During this process, half of the filter screen 20 remains open, and the other half is in a closed state, so that when filtering the next batch of traditional Chinese medicine, several filter screens 20 can be opened alternately to achieve uninterrupted operation, and the filter screen 20 in the closed state can be cleaned with distilled water.

[0071] During the filtering process, the air cylinder 22 acts, driving the liquid blocking plate 25 to move through the lifting rod 23, so that the filter screen 20 is sequentially connected to the inside of the reaction cylinder 1. When a certain filter screen 20 is working, the adjacent filter screen 20 is blocked by the liquid blocking plate 25 and is cleaned at the same time. The power motor 36 is started, driving the rubber scraping plate 41 to reciprocate vertically. The main pump 27 transports the distilled water in the liquid cylinder 26 to the cleaning interlayer 11 through the conduit 28, cooperating with the rubber scraping plate 41 to clean the inner side of the filter screen 20. The limit groove 42 on the rubber scraping plate 41 can release the distilled water more evenly.

[0072] For the outside of the filter screen 20, the driving motor 29 drives the brush roller 31 to rotate and move along the outside of the filter screen 20 for cleaning. The waste liquid and impurities after cleaning are discharged through the liquid guide groove 10. The pneumatic push rod 4 pushes the lifting push plate 5 and the liquid discharge plate 3 to open the liquid guide groove 10, and the auxiliary pump 8 pumps the waste liquid into the liquid collection bucket 9 for centralized treatment. If it is necessary to heat the traditional Chinese medicine liquid, the heater 18 heats the arc-shaped disk 13 through the heat conduction pipe 19, and then heats the traditional Chinese medicine liquid to meet different filtering requirements. Through the coordinated operation of each component, efficient filtration of the traditional Chinese medicine liquid and cleaning and maintenance of the filter screen 20 are realized.

[0073] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
