Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine plaster production technology, and in particular to a raw material filtration device for the production of traditional Chinese medicine plasters. Background Technology

[0002] In the production process of traditional Chinese medicine plasters, raw material filtration is one of the key steps to ensure product quality. The raw materials for traditional Chinese medicine plasters are mostly formed from various Chinese medicinal herbs through extraction and concentration processes. Their composition is complex, often containing impurities such as fibrous residues and incompletely dissolved particulate matter in addition to the active ingredients.

[0003] However, existing technologies, such as Chinese patent application CN213347999U, describe a filtration device for extracting traditional Chinese medicine. This device includes a filter housing. A first filter screen is bolted to the center of the inner wall of the filter housing, and a second filter screen is slidably fitted between two symmetrically shaped grooves at the bottom of the inner wall. The device uses a three-phase motor with a forward / reverse switch to rotate, allowing the pressure plate outside the threaded rod to move up and down, repeatedly squeezing the raw material on the first filter screen to quickly separate the residue from the liquid. The second filter screen further filters large particles of residue squeezed into the liquid, preventing them from becoming impurities and affecting subsequent liquid production. The liquid, filtered by both the first and second filters, is discharged through an outlet pipe. Overall, the device uses two filters for double-layer filtration of the traditional Chinese medicine raw materials, improving the applicability of the extraction filtration device.

[0004] However, during use, it can be observed that fibrous impurities in the herbal raw materials easily accumulate on the filter screen surface, and some particulate impurities may become embedded in the filter screen's pores. As the filtration process continues, the effective filtration area of ​​the filter screen gradually decreases, the filtration resistance continuously increases, leading to a significant decrease in the filtration rate, and even complete clogging of the filter screen. Once the filter screen is clogged, the machine must be stopped to disassemble, clean, or replace it. This not only interrupts the production process and increases the labor intensity of the operators but also prolongs the overall production cycle and reduces production efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problems of easy clogging of filters and low filtration efficiency in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a raw material filtration device for the production of traditional Chinese medicine plasters, comprising a feeding hopper; a crushing chamber connected to and installed at the bottom of the feeding hopper; a crushing component rotatably installed inside the crushing chamber and positioned directly below the feeding hopper; a filtering chamber connected to and installed at the bottom of the crushing chamber; a filtering component movably installed inside the filtering chamber and capable of vibrating up and down within the filtering chamber; and a rinsing component movably installed inside the filtering chamber and capable of reciprocating above the filtering component.

[0007] The technical advantages of adopting the above-mentioned further solution are as follows: The device feeds materials through a hopper, which then crush the raw materials in the crushing chamber before they enter the filtration chamber. The up-and-down vibration of the filter element ensures efficient filtration, while the reciprocating movement of the rinsing element cleans the filter element and prevents clogging, thus achieving efficient filtration of raw materials, reducing waste, and improving the processing effect and efficiency of raw materials for traditional Chinese medicine plasters.

[0008] In a preferred embodiment, the compaction component includes: a set of compaction rollers symmetrically arranged and rotatably mounted inside the compaction chamber; a rotating shaft riveted to the middle of the two compaction rollers, with both ends penetrating the outer wall of the compaction chamber and extending outward; two sets of gear transmission components riveted to the ends of the two rotating shafts, enabling the two compaction rollers to rotate relative to each other; and a drive motor located on one side of the gear transmission components, with its output end connected to the gear transmission components; wherein the two compaction rollers are located directly below the lower opening of the hopper.

[0009] The technical effect of adopting the above-mentioned further solution is that the drive motor drives the rotating shaft through the gear transmission component, causing the sets of crushing rollers in the crushing chamber to rotate relative to each other. Because it is located directly below the feed hopper, it can directly crush the falling raw materials, initially achieving the separation of drug residue and drug liquid, facilitating subsequent filtration, and improving the utilization rate of raw materials and processing efficiency.

[0010] In a preferred embodiment, the filter element includes: two mounting brackets symmetrically arranged and movably installed inside the filter chamber; and multiple filter frames arranged vertically and movably installed between the two mounting brackets; wherein each filter frame has multiple filter holes that pass through it, and the filter holes on the multiple filter frames decrease in size from top to bottom.

[0011] The technical effect of adopting the above-mentioned further solution is that the filter frame is equipped with filter holes, and the hole diameter gradually decreases from top to bottom, which can finely filter the raw materials step by step. The upper layer blocks large particles and the lower layer filters small impurities, thereby improving the filtration accuracy and effect.

[0012] In a preferred embodiment, the filter element further includes: a connecting column, welded to the top of the two mounting brackets, with one end extending through the top of the filter chamber and outwards; a rotating disk, riveted to the outside of the rotating shaft, with a fixing column welded to its surface; wherein the top of the connecting column is rotatably connected to the fixing column, and the fixing column and the rotating disk are not concentrically arranged. This allows the filter frame to vibrate up and down within the filter chamber. It also achieves a linkage effect between the compaction component and the filter element.

[0013] The technical advantages of adopting the above-mentioned further solution are as follows: the filter element is rotatably connected to the fixed column on the rotating disk via the connecting column. Because the fixed column and the rotating disk are not concentric, the rotation causes the mounting frame and filter frame to vibrate up and down, thereby improving the filtration efficiency. At the same time, it realizes the linkage between the crushing component and the filter element, reduces the power source, optimizes the structure, and enhances practicality.

[0014] In a preferred embodiment, the filter element further includes: a positioning block, welded to the left and right sides of the filter frame; and positioning grooves, symmetrically formed on opposite sides of the two mounting brackets; wherein the positioning block and the positioning groove cooperate with each other.

[0015] The technical advantages of adopting the above-mentioned further solution are: it enables multiple filter frames to be precisely aligned between the mounting frames, avoiding installation misalignment from affecting filtration, while facilitating the disassembly and replacement of filter frames in the future, reducing maintenance difficulty, and ensuring the continuous, stable and efficient operation of the filter components.

[0016] In a preferred embodiment, the flushing component includes: a main pipe, movably installed inside the filter chamber; multiple high-pressure nozzles, connected and installed outside the main pipe; a water tank, installed outside the filter chamber, with one end connected to the main pipe via a corrugated connecting pipe; and a pressure regulating valve, installed on the corrugated connecting pipe.

[0017] The technical advantages of adopting the above-mentioned further solution are as follows: In the rinsing component, the water tank is supplied with water through the main pipeline via a corrugated connecting pipe, and multiple sets of high-pressure nozzles can spray water to clean the filter element. The pressure regulating valve can adjust the water pressure to adapt to different cleaning needs, avoid damage to the filter element or incomplete cleaning due to improper water pressure, ensure the cleanliness of the filter element, prevent filter pore blockage, and maintain filtration efficiency.

[0018] In a preferred embodiment, the flushing component further includes: a connecting frame riveted to the left and right sides of the main pipe; two hydraulic shafts installed outside the filter chamber, with their output ends connected to telescopic rods; wherein the movable end of the telescopic rod penetrates the inner wall of the filter chamber and is riveted to the connecting frame, and the axial direction of the telescopic rod is parallel to the filter frame.

[0019] The technical effect of adopting the above-mentioned further solution is that the hydraulic shaft drives the telescopic rod to extend and retract, and through the connecting frame, it drives the main pipeline to move in the parallel direction of the filter frame, and cooperates with the high-pressure nozzle to achieve a comprehensive rinsing of the filter element.

[0020] In a preferred embodiment, the raw material filtration device for the production of traditional Chinese medicine plasters further includes: a leakage tank, movably installed between the crushing component and the filter component, and having multiple leakage holes through its middle; a sealing door, hinged to the outside of the filter chamber; and a collection chamber, connected to the bottom of the filter chamber, with a collection drawer installed inside via guide rails.

[0021] The technical advantages of adopting the above-mentioned further solutions are: the leakage tank collects the squeezed medicine residue, and the leakage hole allows the residual medicine liquid to flow down; the sealed door facilitates the maintenance of the filter element; and the collection drawer can collect the filtered medicine liquid.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. This utility model solves the problems of easy clogging and low filtration efficiency of existing devices by using a dual design of vibration anti-clogging and high-pressure flushing. On the one hand, the device uses the linkage structure of the crushing and filtering components to achieve dynamic anti-clogging: when the drive motor drives the crushing roller to rotate, it synchronously drives the rotating disk to rotate. Because the fixed column and the rotating disk are not concentric, the connecting column pulls the mounting frame and filter frame to vibrate up and down at high frequency. This vibration can continuously shake off the medicinal residue attached to the surface of the filter frame and inside the filter holes. When the medicinal liquid carries the medicinal residue through the filter frame, the vibration can break the adsorption force between the medicinal residue and the filter holes, preventing the medicinal residue from accumulating at the edge of the filter holes to form a clogging layer. Especially for the highly viscous components in Chinese medicine raw materials, it can effectively reduce the initial cause of filter hole clogging. On the other hand, when the filtration operation is completed or when regular maintenance is required, the hydraulic shaft drives the telescopic rod to extend and retract, driving the main pipeline to move back and forth along the parallel direction of the filter frame. At the same time, the water in the water tank is regulated by the pressure regulating valve and sprayed out at a suitable water pressure through the high-pressure nozzle. High-pressure water flow can directly impact the filter holes and surface residue of the filter frame. It is especially effective against stubborn blockages that have not been completely cleared by vibration. It can penetrate deep into the filter holes and flush them away. The independent structure of the multi-layer filter frame, combined with the convenient opening and closing of the sealed door, ensures that there are no dead corners in the rinsing process. This avoids the cumbersome process of disassembling the filter screen for cleaning that is required in traditional devices. It protects the integrity of the filter screen structure, completely solves the clogging problem, and extends the service life of the filter screen.

[0024] 2. This invention significantly improves the filtration efficiency of the device through a multi-level gradient filtration and vibration-accelerated penetration design. Firstly, the device employs multiple sets of vertically distributed filter frames, with the filter pore size decreasing from top to bottom. The crushed mixture first passes through the upper large-pore filter frame to intercept larger particles of medicinal residue. After initial separation, the medicinal liquid then flows through the middle and lower smaller-pore filter frames, gradually removing fine impurities. Secondly, the vibration structure and gradient filtration create a synergistic effect. During vibration, the relative motion between the medicinal liquid and the filter screen surface is enhanced, reducing the residence time of the medicinal liquid on the filter screen surface. Simultaneously, it breaks down the concentration difference of the medicinal liquid near the filter pores, promoting the rapid passage of active ingredients through the filter pores.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1:

[0034] Please see Figures 1-5 This embodiment provides a raw material filtration device for the production of traditional Chinese medicine plasters, which separates medicinal residue from medicinal liquid. The specific idea is as follows:

[0035] A raw material filtration device for the production of traditional Chinese medicine plasters includes a feeding hopper 1. The raw material filtration device for the production of traditional Chinese medicine plasters also includes: a crushing chamber 2, a crushing component 3, a filtering chamber 5, a filtering component 4, a rinsing component 6, a leakage tank 10, a sealing door 7, a collection chamber 8, and a collection drawer 9.

[0036] The top of the compaction chamber 2 is connected to the bottom of the hopper 1.

[0037] Among them, the crushing component 3 is the core component for realizing the pretreatment of raw materials. It can rotate relative to the crushing chamber 2 to squeeze out the liquid medicine from the residue.

[0038] As examples, in this embodiment, the rolling element 3 includes: a rolling roller 301, a rotating shaft 302, a gear transmission element 303, and a drive motor 304.

[0039] Among them, the rolling element 3 is composed of a set of symmetrically distributed rolling rollers 301.

[0040] It should be noted that the two symmetrically arranged rolling rollers 301 are rotatably installed inside the rolling chamber 2 via the central rotating shaft 302, and the two ends of the rotating shaft 302 penetrate through the outer wall of the rolling chamber 2 and extend outward.

[0041] In addition, two sets of gear transmission components 303 are assembled at the extended end of the rotating shaft 302.

[0042] It should be noted that the relative rotation of the two rolling rollers 301 is achieved through gear meshing.

[0043] One side of the gear transmission component 303 is connected to a drive motor 304.

[0044] It should be noted that the motor output power is transmitted to the rotating shaft 302 through the gear transmission component 303, which drives the rolling roller 301 to rotate.

[0045] In addition, the two rolling rollers 301 are positioned directly below the lower opening of the hopper 1, ensuring that the raw material can fall directly between the two rolling rollers 301 after entering from the hopper 1.

[0046] In addition, the bottom of the compaction chamber 2 is connected to the filter chamber 5.

[0047] A leakage groove 10 is movably installed between the rolling element 3 and the filter element 4, and multiple leakage holes 11 are provided in the middle of the leakage groove 10.

[0048] Meanwhile, the bottom of the filter chamber 5 is connected to the collection chamber 8.

[0049] The collection chamber 8 contains a collection drawer 9 installed inside via guide rails.

[0050] In addition, a sealing door 7 is hinged to the outside of the filter chamber 5.

[0051] In this embodiment, when the drive motor 304 drives the two crushing rollers 301 to rotate relative to each other through the gear transmission component 303, it can crush the Chinese herbal raw materials fed from the feed hopper 1, making it easier for the effective components in the raw materials to be extracted. The crushed mixture enters the filter chamber 5 through the leakage hole 11 of the leakage tank 10, while the larger dregs are collected by the leakage tank 10, realizing the initial separation of raw materials and laying the foundation for the subsequent filtration process.

[0052] Example 2:

[0053] like Figures 1-5 As shown in Example 1, this example provides a raw material filtration device for the production of traditional Chinese medicine plasters that achieves efficient filtration of medicinal liquid. The specific idea is as follows:

[0054] The raw material filtration device for the production of traditional Chinese medicine plasters also includes: filter element 4.

[0055] Among them, the filter element 4 is the key component for achieving fine filtration of raw materials, and it is movably installed inside the filter chamber 5.

[0056] As examples, in this embodiment, the filter element 4 includes: a mounting bracket 401, a filter frame 402, a positioning block 403, a positioning groove 404, a connecting column 405, a rotating disk 406, and a fixing column 407.

[0057] The filter element 4 includes two symmetrically arranged mounting brackets 401.

[0058] Meanwhile, multiple filter holders 402 are vertically distributed and movably installed between the two mounting brackets 401.

[0059] It should be noted that each filter holder 402 has multiple filter holes through it, and the size of the filter holes decreases from top to bottom.

[0060] In addition, positioning blocks 403 are welded to the left and right sides of the filter frame 402.

[0061] The two mounting brackets 401 have symmetrically arranged positioning grooves 404 on opposite sides.

[0062] It should be noted that the positioning block 403 and the positioning groove 404 cooperate with each other to ensure that the filter frame 402 is stably installed on the mounting frame 401 and is easy to disassemble and replace.

[0063] In addition, a connecting post 405 is welded to the top of the mounting bracket 401.

[0064] It should be noted that one end of the connecting column 405 passes through the top of the filter chamber 5 and extends outward.

[0065] Meanwhile, a rotating disk 406 is riveted to the outside of the rotating shaft 302 of the rolling part 3.

[0066] Among them, the rotating disk 406 has a fixed column 407 welded on its surface.

[0067] It should be noted that the fixed column 407 and the rotating disk 406 are not concentrically arranged.

[0068] In addition, the top of the connecting column 405 is rotatably connected to the fixed column 407 to form a linkage structure.

[0069] In this embodiment, when the rotating shaft 302 rotates, it drives the rotating disk 406 to rotate synchronously. Since the fixed column 407 is not concentric with the rotating disk 406, it pulls the mounting frame 401 up and down through the connecting column 405, causing the filter frame 402 to vibrate within the filter chamber 5. This vibration, combined with the multiple layers of filter frames 402 with different pore sizes, allows for progressively fine filtration of the crushed raw material, improving filtration efficiency. Simultaneously, the crushing component 3 and the filter component 4 are mechanically linked, reducing the use of a power source and lowering equipment energy consumption.

[0070] Example 3:

[0071] like Figures 1-5 As shown in Example 2, this example provides a raw material filtration device for the production of traditional Chinese medicine plasters that can improve the cleanliness of the filtration components. The specific idea is as follows:

[0072] The raw material filtration device for the production of traditional Chinese medicine plasters also includes: rinsing component 6.

[0073] The flushing component 6, used for cleaning and maintaining the filter element 4, is installed inside the filter chamber 5.

[0074] As examples, in this embodiment, the flushing component 6 includes: a main pipe 601, a high-pressure nozzle 602, a corrugated connecting pipe 603, a water tank 604, a pressure regulating valve 605, a connecting frame 606, a hydraulic shaft 607, and a telescopic rod 608.

[0075] The main pipe 601 is movably installed inside the filter chamber 5.

[0076] In addition, multiple sets of high-pressure nozzles 602 are installed on the external connection of the main pipe 601.

[0077] Meanwhile, a water tank 604 is installed outside the filter chamber 5.

[0078] The water tank 604 is connected to the main pipe 601 via a corrugated connecting pipe 603.

[0079] It should be noted that a pressure regulating valve 605 is installed on the corrugated connecting pipe 603 to control the flushing water pressure.

[0080] Connecting brackets 606 are riveted to both sides of the main pipe 601.

[0081] Meanwhile, two hydraulic shafts 607 are mounted on the outside of the filter chamber 5.

[0082] The output end of the hydraulic shaft 607 is connected to a telescopic rod 608.

[0083] In addition, the movable end of the telescopic rod 608 penetrates the inner wall of the filter chamber 5 and is riveted to the connecting frame 606, and the axial direction of the telescopic rod 608 is parallel to the filter frame 402.

[0084] It should be noted that the flushing component 6 is located above the filter component 4, and its range of motion covers the entire area of ​​the filter frame 402. Together with the filter chamber 5, filter component 4, and other structures, it constitutes a complete filtration system.

[0085] In this embodiment, after prolonged use, the filter element 4 is extended or retracted via the hydraulic shaft 607 driving the telescopic rod 608, which in turn causes the main pipe 601 to move cyclically along the parallel direction of the filter frame 402. Simultaneously, water from the water tank 604 is transported to the main pipe 601 via the corrugated connecting pipe 603 and sprayed out at a set pressure through the high-pressure nozzle 602 to thoroughly rinse the filter frame 402. This process effectively removes residual dregs from the filter holes of the filter frame 402, preventing clogging and ensuring stable filtration efficiency. The pressure regulating valve 605 adjusts the water pressure according to the degree of clogging of the filter frame 402, preventing damage to the filter frame 402 due to excessive water pressure. The flexible design of the corrugated connecting pipe 603 adapts to the movement requirements of the main pipe 601, ensuring a stable water supply.

[0086] Working Principle: This equipment is a raw material filtration device for the production of traditional Chinese medicine plasters. In use, the raw materials to be processed are first fed into the hopper 1, and then enter the crushing chamber 2. The drive motor 304 is turned on, and power is transmitted to the rotating shaft 302 through the gear transmission component 303, driving two sets of crushing rollers 301 to rotate relative to each other, crushing the raw materials. The crushed mixture falls into the drain trough 10, and the medicinal liquid flows into the filter chamber 5 through the drain holes 11, while larger medicinal residues remain in the drain trough 10. During this process, the rotating shaft 302 synchronously drives the rotating disk 406 to rotate. Because the fixed column 407 is not concentric with the rotating disk 406, the connecting column 405 pulls the mounting frame 401 up and down, causing the filter frame 402 to vibrate. Under the action of vibration, the medicinal liquid is filtered step by step through the multi-layer filter frame 402, with the filter holes decreasing in size from top to bottom, achieving fine separation. Finally, the filtered medicinal liquid flows into the collection tray 9 of the collection chamber 8. After filtration is complete, turn off the drive motor 304, open the sealing door 7 to remove the leakage tank 10 to clean the residue, and pull out the collection tray 9 through the guide rail to collect the liquid. If it is necessary to clean the filter frame 402, start the hydraulic shaft 607, and the telescopic rod 608 drives the main pipe 601 to move back and forth along the filter frame 402. At the same time, the water in the water tank 604 is transported to the high-pressure nozzle 602 through the corrugated connecting pipe 603 to flush the filter frame 402 at the set pressure, remove residual impurities in the filter holes, and ensure filtration efficiency for the next use.
