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

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] refer to Figures 1 to 10 , a Chinese medicine liquid filtering device, comprising: The reaction tube 1 has a plurality of positioning holes 2 formed at equal angles along the circumferential direction at the lower end of the reaction tube 1 (such as Figure 3 As shown), the upper end of the reaction tube 1 is formed with a plurality of cleaning interlayers 11 at equal angles along the circumferential direction; Centrifugal mechanism 12 (such as Figure 6 As shown), it is arranged at the lower part of the reaction tube 1, and includes an arc-shaped disk 13 coaxially rotatably connected to the lower end of the reaction tube 1; A plurality of filter screens 20 are respectively fixedly connected to the plurality of positioning holes 2; A plurality of flow guide mechanisms 21, corresponding to a plurality of cleaning interlayers 11 one by one, each flow guide mechanism 21 comprises a liquid baffle plate 25, a rolling brush 31 and a rubber scraper 41, the liquid baffle plate 25 is arranged on a side of the filter screen 20 close to the axis of the reaction cylinder 1, the rubber scraper 41 is arranged on a side of the liquid baffle plate 25 close to the filter screen 20, and the rolling brush 31 is arranged on a side of the filter screen 20 away from the axis of the reaction cylinder 1; A plurality of drainage covers 44 are respectively disposed outside the plurality of filter screens 20 and are fixedly connected to the outer wall of the reaction tube 1 .

[0027] When the device is in operation, the operator pours the Chinese medicine liquid to be filtered into the reaction cylinder 1, and then the Chinese medicine liquid falls into the arc disk 13. Then, when the arc disk 13 rotates (the specific rotation process is explained later), the Chinese medicine liquid will flow in the direction away from the axis of the reaction cylinder 1 under the action of centrifugal force until the Chinese medicine liquid contacts the corresponding filter screen 20. Then, the Chinese medicine liquid passes through the filter screen 20 and is guided to the collection tank through the corresponding drainage cover 44.

[0028] During this process, several filter screens 20 are connected to the inside of the reaction cylinder 1 in turn, that is, during the filtering process of the traditional Chinese medicine liquid, one of the two adjacent filter screens 20 is blocked by the corresponding liquid blocking plate 25, and the inner side of the blocked filter screen 20 is cleaned by the rubber scraper 41, and the outer side is cleaned by the roller 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.

[0029] In order to drive the arc-shaped disk 13 to rotate, the following features are also specifically provided: The centrifugal mechanism 12 also includes an active motor 14, an active gear 15, an active gear ring 16 and an adapter plate 17. The active motor 14 is fixedly arranged below the reaction tube 1. The active gear 15 is coaxially fixedly connected to the output end of the active motor 14. The adapter plate 17 is coaxially rotatably arranged at the lower end of the reaction tube 1. The upper end of the adapter plate 17 is fixedly connected to the arc disk 13, and the lower end is fixedly connected to the active gear ring 16. The active gear ring 16 is meshed with the active gear 15. After the active motor 14 is started, its output end drives the active gear 15 to rotate, and the active gear 15 is meshed with the active gear ring 16, thereby driving the adapter plate 17 to rotate around the axis of the lower end of the reaction tube 1. Since the upper end of the adapter plate 17 is fixedly connected to the arc disk 13, the arc disk 13 also rotates synchronously therewith, providing power for filtering the Chinese medicine liquid under the action of centrifugal force.

[0030] 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 liquids, thereby increasing the scope of the device, the following features are also set: The centrifugal mechanism 12 further includes a heater 18 and a heat pipe 19. The heater 18 is fixedly arranged beside the active motor 14. The heat pipe 19 is arranged at the lower end of the arc disk 13 and is coaxially fixedly connected with the output end of the heater 18. When filtering the Chinese medicine liquid that needs to be heated, the heater 18 is turned on, and the heat generated by the heater 18 is transferred to the arc disk 13 through the heat pipe 19. After the arc disk 13 is heated, it can heat the Chinese medicine liquid located thereon, thereby increasing the temperature of the Chinese medicine liquid, meeting the filtering requirements of different types of Chinese medicine liquids, and expanding the scope of application of the device.

[0031] In order to drive the liquid baffle plate 25 to move and ensure that the plurality of filter screens 20 can be sequentially connected to the interior of the reaction cylinder 1, the following features are also specifically provided: The flow guiding mechanism 21 also 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 tube 1. The two limiting rods 24 are respectively arranged on both sides of the liquid baffle plate 25. The two ends of the limiting rod 24 are respectively connected to the inner wall of the reaction tube 1. The upper end of the lifting rod 23 is connected to the output end of the cylinder 22, and the lower end is connected to the upper end of the liquid baffle plate 25. When it is necessary to switch the internal connection state of the filter screen 20 and the reaction tube 1, the cylinder 22 is started, the output end of the cylinder 22 is extended or retracted, and the lifting rod 23 is driven to move up and down. The lifting rod 23 then pushes the liquid baffle plate 25 to move up and down along the direction defined by the limiting rod 24, so as to achieve the blocking or release of the filter screen 20, so that a plurality of filter screens 20 can be connected to the inside of the reaction tube 1 in sequence, and the filtering operation is carried out in an orderly manner.

[0032] In order to drive the rubber scraper 41 to reciprocate in the vertical direction and ensure that the rubber scraper 41 can clean the inner side of the filter screen 20 during the movement, the following features are specifically provided: The flow guide mechanism 21 also includes a power motor 36, a power gear 37, a reciprocating gear 38, a reciprocating screw sleeve 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 tube 1 (refer to Figure 7 ), the power gear 37 is coaxially connected to the output end of the power motor 36, the reciprocating gear 38 is rotatably connected to the upper end of the reaction tube 1 and meshes with the power gear 37, the reciprocating screw sleeve 39 is coaxially connected to the reciprocating gear 38, the reciprocating screw 40 is threadedly connected to the reciprocating screw sleeve 39, and the extrusion guide plate 43 is slidably connected to the cleaning interlayer 11 (reference Figure 8 ), the lower end of the extrusion guide plate 43 is fixedly connected to the upper end of the rubber scraper 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, and the reciprocating gear 38 drives the reciprocating screw sleeve 39 coaxial therewith to rotate. Since the reciprocating screw 40 is threadedly connected to the reciprocating screw sleeve 39, and the extrusion guide plate 43 limits the rotation of the reciprocating screw 40, the reciprocating screw 40 reciprocates in the vertical direction under the action of the reciprocating screw sleeve 39, thereby driving the extrusion guide plate 43 and the rubber scraper 41 connected thereto to reciprocate in the vertical direction, thereby achieving cleaning of the inner side of the filter screen 20.

[0033] In order to provide distilled water to the filter screen 20 during the movement of the rubber scraper 41, thereby improving the cleaning effect of the filter screen 20, the following features are specifically set: The upper coaxial line of the reaction cylinder 1 is fixedly connected with a fluid cylinder 26, and the flow guiding mechanism 21 also includes a main pump 27 and a conduit 28, the main pump 27 is arranged at the lower end of the fluid cylinder 26 and the input end is communicated with the fluid 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 clean interlayer 11. In the process that the rubber scraper 41 cleans the filter screen 20, the main pump 27 is started, the main pump 27 extracts the distilled water in the fluid cylinder 26, and is transported to the clean interlayer 11 through the conduit 28, and the distilled water flows out from the clean interlayer 11, and when the rubber scraper 41 moves, the distilled water is provided to the filter screen 20, thereby enhancing the cleaning effect of the filter screen 20 and effectively removing the impurities attached to the filter screen 20.

[0034] In order to ensure that the distilled water in the liquid cylinder 26 can fall during the reciprocating movement of the rubber scraper 41, and to facilitate the cleaning of the filter screen 20, the following features are specifically provided: A plurality of limiting grooves 42 are formed at equal intervals on one side of the rubber scraper 41 close to the filter screen 20 (see Fig. 9 ). During the movement of the rubber scraper 41, the limiting groove 42 can store a certain amount of distilled water. As the rubber scraper 41 moves, the distilled water is evenly released onto the filter 20, which not only ensures that all parts of the filter 20 can be fully cleaned, but also makes the distilled water more uniform, improves the cleaning effect, and also helps to reduce the waste of distilled water.

[0035] In order to quickly discharge the cleaning liquid and remove the impurities remaining in the reaction tube 1, the following features are also provided: The lower end of each positioning hole 2 is formed with a liquid guide groove 10 (refer to Figure 3 ), the flow guiding mechanism 21 also includes a liquid discharge plate 3, a lifting push plate 5, two pneumatic push rods 4 and two lifting shafts 6, and the liquid discharge plate 3 is slidably connected to the upper end of the liquid guide groove 10 (refer to Figure 4 and Figure 5 ), the upper ends of the two lifting shafts 6 are respectively fixedly connected to the lower ends of the drainage plate 3, the lower ends of the two lifting shafts 6 are respectively fixedly connected to the upper ends of the lifting push plates 5, and the two pneumatic push rods 4 are respectively arranged at the lower ends of the lifting push plates 5 and the output ends are fixedly connected to the lifting push plates 5. When it is necessary to discharge the cleaning liquid and remove the residual impurities in the reaction cylinder 1, the two pneumatic push rods 4 are started, and their output ends push the lifting push plates 5 to move upward, and the lifting push plates 5 drive the drainage plate 3 to move upward through the lifting shafts 6, opening the liquid guide groove 10, so that the cleaning liquid and impurities can be smoothly discharged through the liquid guide groove 10, realizing the rapid discharge of the cleaning liquid and the effective removal of the residual impurities in the reaction cylinder 1.

[0036] In order to facilitate the centralized treatment of the waste liquid flowing into the liquid guiding groove 10, the following features are also specifically provided: The lower coaxial line of the reaction cylinder 1 is fixedly connected with a liquid collecting barrel 9, and the flow guiding mechanism 21 also includes a liquid guiding tube 7 and an auxiliary pump 8. The auxiliary pump 8 is arranged on the side of the liquid guiding groove 10 close to the liquid collecting barrel 9, one end of the liquid guiding tube 7 is connected with the liquid guiding groove 10, and the other end is connected with the input end of the auxiliary pump 8, and the output end of the auxiliary pump 8 is connected with the liquid collecting barrel 9. After the cleaning liquid and impurities are discharged through the liquid guiding groove 10, the auxiliary pump 8 is started, and the auxiliary pump 8 sucks the waste liquid in the liquid guiding groove 10 through the liquid guiding tube 7 and transports it to the liquid collecting barrel 9, realizing the centralized collection and treatment of the waste liquid, facilitating the subsequent unified disposal of the waste liquid, and avoiding the pollution to the environment caused by the random discharge of the waste liquid.

[0037] In order to facilitate the rolling brush 31 to rotate while moving along the side of the filter screen 20 away from the axis of the reaction tube 1, the following features are also specifically provided: The lower coaxial line of the fluid cylinder 26 is fixedly connected with an annular guide rail 34, and the lower coaxial line of the annular guide rail 34 is fixedly connected with an annular gear ring 30 (such as Figure 5 As shown in FIG. 1 ), the flow guide mechanism 21 further includes a drive motor 29, a limit gear 33, a brush holder 32 and a limit claw 35, and the limit claw 35 is slidably connected to the annular guide rail 34 (as shown in FIG. 1 ). Figure 4 As shown in FIG. 1 ), the limit claw 35 is fixedly connected to the brush holder 32, the brush holder 32 is rotatably connected to both ends of the roller brush 31, and the limit gear 33 (as shown in FIG. Fig. 9 As shown in the figure, the upper end of the limit claw 35 is rotatably connected and meshed with the annular gear ring 30. The drive motor 29 is fixedly connected to the upper end of the limit claw 35 and the output end is fixedly connected to the limit gear 33 coaxially. When cleaning the outside of the filter screen 20, the drive motor 29 is started, and the output end of the drive motor 29 drives the limit gear 33 to rotate, and the limit gear 33 meshes with the annular gear ring 30. Since the limit claw 35 is connected to the brush holder 32 and slides on the annular guide rail 34, the limit claw 35 moves in a circle along the annular guide rail 34 under the drive of the limit gear 33. At the same time, the drive motor 29 also drives the roller brush 31 to rotate, so that the roller 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.

[0038] The working principle of the device is that when the device is working, the operator first pours the Chinese medicine liquid to be filtered into the reaction cylinder 1. The active motor 14 is started, and the active motor 14 drives the active gear 15 to rotate, and the active gear 15 is meshed with the active gear ring 16, so that the connecting plate 17 and the arc disk 13 connected thereto rotate. Under the centrifugal force generated by the rotation of the arc disk 13, the Chinese medicine liquid flows 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. In this process, half of the filter screen 20 remains in an open state, and the other half of the filter screen 20 is in a closed state, so that when the next batch of Chinese medicine is filtered later, several filter screens 20 can be opened in turn to achieve uninterrupted operation, and the filter screen 20 in the closed state can be cleaned with distilled water.

[0039] During the filtering process, the cylinder 22 is in motion, and the liquid baffle plate 25 is driven to move through the lifting rod 23, so that the filter screen 20 is connected to the inside of the reaction cylinder 1 in sequence. When a certain filter screen 20 is working, the adjacent filter screen 20 is blocked by the liquid baffle plate 25 and cleaned at the same time. The power motor 36 is started, driving the rubber scraper 41 to move back and forth in the vertical direction, and the main pump 27 transports the distilled water in the liquid cylinder 26 to the cleaning interlayer 11 through the conduit 28, and cooperates with the rubber scraper 41 to clean the inside of the filter screen 20, and the limiting groove 42 on the rubber scraper 41 can release the distilled water more evenly.

[0040] For the outside of the filter 20, the driving motor 29 drives the roller brush 31 to rotate and move along the outside of the filter 20 for cleaning. The cleaned waste liquid and impurities are discharged through the liquid guide groove 10, and 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 barrel 9 for centralized treatment. If there is a Chinese medicine liquid that needs to be heated, the heater 18 heats the arc disk 13 through the heat pipe 19, and then heats the Chinese medicine liquid to meet different filtering requirements. Through the coordinated operation of various components, efficient filtration of the Chinese medicine liquid and cleaning and maintenance of the filter 20 are achieved.

[0041] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
