Technical Field
[0001] This invention relates to the field of medicinal liquid filtration devices, and in particular to a liquid filter paper separation device for Chinese herbal medicine residue. Background Technology
[0002] The liquid-filtration paper separation equipment for Chinese herbal medicine residue is a key auxiliary device in the extraction and production process of Chinese herbal medicine. Its main function is to achieve efficient separation of the medicinal liquid and the residue, ensuring the purity and quality of Chinese herbal preparations. Firstly, this equipment utilizes a special filter medium (usually special filter paper) with its precise pore structure to effectively intercept fine residue, suspended particles, and impurities remaining after decoction or extraction of Chinese herbal medicine. This not only solves the problems of turbidity and clogging in traditional separation methods but also significantly improves the clarity and transparency of the medicinal liquid. Secondly, this equipment significantly improves production efficiency. Through automated or mechanized filtration and extrusion mechanisms, it can quickly complete solid-liquid separation, shortening the production cycle. Simultaneously, the moisture content of the separated residue is significantly reduced, minimizing the waste of effective components and facilitating subsequent residue treatment and resource recycling. Furthermore, this equipment plays a crucial role in ensuring the efficacy of the medicine. It maximizes the retention of effective active ingredients in the medicinal liquid during the separation process, avoiding efficacy loss due to improper filtration. In conclusion, the liquid filter paper separation equipment for Chinese herbal medicine residue plays an irreplaceable role in improving the modernization level of Chinese herbal medicine production, reducing production costs, and ensuring drug safety.
[0003] Traditional filter paper separation equipment is widely used in the pharmaceutical industry, but due to limitations in its structure and working principle, it often suffers from some unavoidable problems. Existing filter paper separation equipment for liquids containing traditional Chinese medicine residues commonly suffers from fixed filter paper shapes and difficulties in adjustment, especially when switching between different filtration modes. The filter paper support structure of such equipment typically adopts an integrated design, with the number and shape of the filter paper layers strictly locked by the mechanical structure. When the production process requires switching from single-layer filtration to multi-layer filtration to meet different precision requirements, the lack of a flexible adjustment mechanism prevents operators from directly adding or removing filter paper layers on the existing equipment. Furthermore, to achieve inter-layer switching, it is often necessary to replace pre-assembled filter paper or prepared filter cartridges with specific layer specifications. This process is not only time-consuming and labor-intensive, severely reducing production continuity, but also frequently increases the procurement costs and inventory burden of filter media. In addition, manually replacing filter paper of different specifications makes it difficult to ensure consistent flatness and sealing during each installation, easily leading to side leakage or incomplete filtration due to installation errors. In summary, the inability to adjust the filter paper shape leads to cumbersome mode switching, which limits the equipment's adaptability to the diverse extraction processes of traditional Chinese medicine, and increases production costs and management difficulty. Summary of the Invention
[0004] Given the existing technical problems that separation equipment cannot change the shape of filter paper to adapt to different usage requirements, a liquid filter paper separation device for Chinese herbal medicine residue is proposed.
[0005] Its purpose is to enable filter paper separation equipment to change the shape of the filter paper, allowing it to switch between single-layer and multi-layer filters.
[0006] The technical solution of the present invention is a liquid filter paper separation device for Chinese herbal medicine residue, including a separator body, a top cover disposed on the top of the separator body, a liquid collection tank disposed on the bottom of the separator body, an air pump disposed on the outside of the liquid collection tank, and an adjustment mechanism disposed inside the separator body. The adjustment mechanism includes pressure plates symmetrically arranged on both sides of the separator body, filter paper arranged at the bottom of the two pressure plates, bolts arranged on both sides of the pressure plates with their bottom ends threaded to the separator body, several horizontal frames arranged in a linear array at the lower middle part of the inner wall of the separator body, several symmetrically opened grooves on the inner wall of the separator body near the two ends of the horizontal frames, sliders arranged inside the grooves, movable plates arranged in two opposite grooves with their ends fixedly connected to the corresponding sliders, vertical rods symmetrically arranged near the two ends of the movable plates, horizontal rods arranged at the top of the vertical rods on the same side of the separator body, lifting rods arranged in the middle of the two horizontal rods, several slots arranged in a linear array on the side of the horizontal rods away from the movable plates, several shells symmetrically arranged on both sides of the inner wall of the separator body near the grooves, pins arranged inside the shells, springs arranged at the ends of the pins away from the horizontal rods with their ends fixedly connected to the pins and the inner wall of the shells respectively, and an expansion unit arranged inside the horizontal frames.
[0007] Furthermore, short shafts are provided at both ends of the movable plate, and the middle part of the short shafts is fixedly connected to the bottom end of the vertical rod.
[0008] Furthermore, a support shaft is provided at the top of the vertical rod, and a shaft hole is provided at the connection between the horizontal rod and all the vertical rods, with the inner wall of the shaft hole rotatably connected to the corresponding support shaft.
[0009] Furthermore, the chute consists of a vertical groove and an arc-shaped groove, with the tops of the vertical groove and the arc-shaped groove connected to each other.
[0010] Furthermore, the expansion unit includes a rack disposed inside the crossbeam, several short plates symmetrically disposed on both sides of the rack, a drive rod disposed on one end of the rack away from the crossbeam, and a knob disposed on the side of the drive rod away from the crossbeam.
[0011] Furthermore, a gear is provided at the connection between the short plate and the cross frame, and the gear meshes with the corresponding rack.
[0012] Furthermore, a limit block is provided in the middle of the drive rod, and the knob is rotatably connected to the limit block on the side near the drive rod.
[0013] Furthermore, the outer side of the knob is provided with threads, and a threaded hole is provided at the connection between the separator body and the knob, with the threaded hole being threadedly connected to the knob.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting an adjustment mechanism, operators can use this mechanism to change the stacking method of the filter paper, setting the filter paper to a single layer or multiple layers. This function enables the equipment to adapt to different usage needs. When facing production scenarios that require different filtration accuracy or throughput, the equipment can flexibly switch working modes by adjusting the number of filter paper layers, which can not only meet basic filtration requirements, but also cope with high-standard separation tasks, thus enhancing the versatility and applicability of the equipment.
[0015] 2. By setting up an expansion unit, after the unit completes the expansion action, the expansion component contacts and supports the top filter paper. The residue accumulates on the filter paper, and the weight increases accordingly. The expansion unit provides continuous support to the filter paper, shares the pressure on the filter paper, prevents the filter paper from breaking due to excessive weight of the residue, ensures that the filter paper remains intact under load, avoids filtration failure due to excessive weight, ensures the stability of the separation process between the liquid medicine and the residue, and maintains the continuous operation of the equipment.
[0016] 3. By setting up filter paper, the mixture of medicinal liquid and residue flows through the surface of the filter paper. Utilizing the interception effect of the filter paper, the residue is blocked on one side of the filter paper, while the medicinal liquid flows through the filter paper to the other side, thereby achieving the separation of medicinal liquid and residue. This process separates solid particles from liquid, obtaining a pure medicinal liquid, which meets the basic requirements for the purity of extract in the production of traditional Chinese medicine and completes a key step in the production process.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0020] Example 1, referring to Figures 1-15This is the first embodiment of the present invention, providing a liquid filter paper separation device for traditional Chinese medicine residue, including a separator body 1, a top cover 2 placed on top of the separator body 1, a liquid collection tank 3 snapped onto the bottom of the separator body 1, a vacuum pump 4 fixedly connected to the outside of the liquid collection tank 3, and an adjustment mechanism 5 installed inside the separator body 1; the adjustment mechanism 5 includes pressure plates 51 symmetrically abutting against both sides inside the separator body 1, filter paper 52 fixedly connected to the bottom of the two pressure plates 51, bolts 53 rotatably connected to both sides of the pressure plates 51, the bottom ends of the bolts 53 threadedly connected to the separator body 1, several linear arrays fixedly connected to the lower middle part of the inner wall of the separator body 1, several symmetrically opened grooves 55 on the inner wall of the separator body 1 near the two ends of the grooves 54, and sliders 56 slidably connected inside the grooves 55. The movable plate 57 is slidably connected inside two opposing slide grooves 55. The two ends of the movable plate 57 are fixedly connected to the corresponding sliders 56. The vertical rods 58 are symmetrically fixedly connected to the movable plate 57 near both ends. The horizontal rods 59 are rotatably connected to the top of the vertical rods 58 on the same side of the separator body 1. The lifting rods 510 are rotatably connected to the middle of the two horizontal rods 59. Several slots 511 are linearly arrayed on the side of the horizontal rods 59 away from the movable plate 57. Several housings 512 are symmetrically fixedly connected to both sides of the inner wall of the separator body 1 near the slide grooves 55. The pins 513 are slidably connected inside the housings 512. The springs 514 are fixedly connected to the end of the pins 513 away from the horizontal rods 59. The two ends of the springs 514 are fixedly connected to the pins 513 and the inner wall of the housings 512, respectively. And the expansion unit is assembled inside the crossbar 54.
[0021] Specifically, when the filter paper 52 needs to be in a single-layer filtration state, rotate all the bolts 53 to release the fixing of the pressure plate 51, allowing the pressure plate 51 to move up and down. Then, pass one end of the filter paper 52 through the bottom of the two pressure plates 51 in sequence, and position the filter paper 52 above all the crossbars 54 and the moving rods. Then, rotate the bolts 53 to move the two pressure plates 51 down to press the filter paper 52 tightly. After the filter paper 52 is pressed, it should be in a flat state, and the flat surface at the top of the crossbar 54 should support the bottom surface of the filter paper 52. Unfold the expansion unit, and then clamp the bottom of the separator body 1 with the collection tank 3. Next, the dregs are placed on top of the filter paper 52 and flattened. Then, the top cover 2 is closed, and the vacuum pump 4 is started to create a negative pressure between the collection tank 3 and the separator body 1. Under the action of negative pressure, the liquid passes through the filter paper 52 and falls into the collection tank 3, completing the filtration. When multi-layer filtration is required, the restriction of the two pressure plates 51 is released, and a filter paper 52 of appropriate length is taken, so that one end passes through the space between the bottom of the cross frame 54 and the top of the movable plate 57. Then, the two ends of the filter paper 52 are fixed by the pressure plates 51. After the two ends of the filter paper 52 are fixed, the two cross bars 59 are moved upward by moving the lifting rod 510 upward. The vertical rod 58 connected to it moves upward, which in turn moves the corresponding movable plate 57 upward. Simultaneously, the movable plate 57 moves the corresponding slider 56 upward. The slider 56, constrained by the slide groove 55, can only move along the slide groove 55, thus ensuring the movable plate can also only move along the slide groove 55. During movement, the movable rod first moves upward with its long side perpendicular to the ground, simultaneously pulling the filter paper 52 upward. Then, after the movable plate 57 reaches its maximum stroke along the arc-shaped groove of the slide groove 55, it deflects towards the adjacent horizontal frame 54 with its wide side facing downward, thus moving the filter... The filter paper 52 is bent, resulting in a multi-layered state. When the lifting rod 510 drives the moving plate to deflect downwards, the crossbar 59 also moves downwards in an arc. After moving down a certain distance, it presses the pin 513, causing the pin 513 to move towards the spring 514. After the crossbar 59 moves down to its maximum stroke, the pin 513 aligns with the slot 511. At this time, the spring 514 pushes the pin 513 out, so that it engages with the slot 511 to fix the crossbar 59, thereby fixing the moving plate. At this time, the dregs are put into the top of the filter paper 52, and the vacuum pump is started to perform multi-layer filtration.
[0022] Reference Figures 8-13 The movable plate 57 has short shafts at both ends, and the middle of the short shafts is fixedly connected to the bottom end of the vertical rod 58.
[0023] Specifically, the movable plate 57 is connected to the corresponding slider 56 via a short shaft, and the vertical rod 58 is also connected to the movable plate 57 via a corresponding short shaft. The short shaft transmits the force from the horizontal rod 59 and the lifting rod 510 to the moving rod, and the slider 56 and the groove 55 at both ends of the short shaft constrain its movement path.
[0024] Reference Figure 10 The top of the vertical rod 58 is provided with a support shaft, and the connection between the horizontal rod 59 and all the vertical rods 58 is provided with shaft holes. The inner wall of the shaft hole is rotatably connected to the corresponding support shaft.
[0025] Specifically, the vertical rod 58 is connected to the horizontal rod 59 via a support shaft, and the support shaft is connected to the shaft hole, allowing the vertical rod 58 and the horizontal rod 59 to rotate relative to each other, so that they can adapt to changes in relative position under different motion states.
[0026] Reference Figures 2-8 The chute 55 consists of a vertical groove and an arc-shaped groove, with the tops of the vertical groove and the arc-shaped groove connected to each other.
[0027] Specifically, the slide 55 restricts the movement path of the movable plate 57 through the cooperation between the vertical groove and the arc groove, so that the movable plate can be in a wide-face downward posture after moving to the maximum stroke under the action of the slider 56, the vertical rod 58 and the horizontal rod 59.
[0028] Example 2, refer to Figures 1-15 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the expansion unit includes a rack 515 slidably connected inside the crossbeam 54, several short plates 516 symmetrically meshing and connected to both sides of the rack 515, a drive rod 517 fixedly connected to one end of the rack 515 away from the crossbeam 54, and a knob 518 rotatably connected to the side of the drive rod 517 away from the crossbeam 54.
[0029] Specifically, by rotating the knob 518, the knob 518 moves along its own axis under the action of the thread, causing the knob 518 to move closer to the crossbeam 54. At the same time, the knob 518 moves, driving the drive rod 517 to move. At the same time, the drive rod 517 moves, driving all the racks 515 to move synchronously. After the racks 515 move, they drive the short plate 516 to move. After being subjected to force, the short plate 516 will rotate around the connection point with the crossbeam 54. Through the drive rod 517, all the short plates 516 can be expanded. After the short plates 516 are rotated to a state perpendicular to the crossbeam 54, the top surfaces of the crossbeam 54 and the short plates 516 will jointly support the filter paper 52.
[0030] Reference Figure 7 A gear is provided at the connection between the short plate 516 and the cross frame 54, and the gear meshes with the corresponding rack 515.
[0031] Specifically, while the rack 515 moves, it drives the short plate 516 to rotate via the gear. The short plate 516 is constrained by the cross frame 54 and can only rotate around the connection point with the cross frame 54. The maximum rotation angle of the cross frame 54 is ninety degrees.
[0032] Reference Figure 6 A limit block is provided in the middle of the drive rod 517, and the knob 518 is rotatably connected to the limit block on the side near the drive rod 517.
[0033] Specifically, the drive rod 517 is connected to the knob 518 through a limit block, so that it can move along the axis of the knob 518 without affecting the rotation of the knob 518.
[0034] Reference Figure 4 and Figure 6 The knob 518 has a thread on its outer side, and a screw hole is provided at the connection between the separator body 1 and the knob 518. The screw hole is threadedly connected to the knob 518.
[0035] Specifically, when the knob 518 is rotated, it will move along its own axis under the action of the thread, and at the same time drive the drive rod 517 to move synchronously. The opening and closing of the expansion unit can be controlled by rotating the knob 518. The rest of the structure is the same as that of Embodiment 1.
[0036] Based on embodiments 1-2, the working principle of this invention is as follows: Switch between single-layer and multi-layer modes according to filtration requirements. In single-layer filtration, rotate bolt 53 to release the pressure plate 51, allowing filter paper 52 to be laid flat on the crossbeam 54 and the lower movable plate 57. Then lock the pressure plate 51. Next, rotate knob 518, which drives drive rod 517 and rack 515 to move via threaded transmission. The rack 515 meshes with gears, causing short plate 516 to rotate perpendicular to the crossbeam 54, forming a large support surface to hold the filter paper 52 and prevent damage. After installing the collection tank 3 and adding the dregs, start the vacuum pump 4. The negative pressure forces the liquid to pass through the filter paper 52, completing the filtration process. During multi-layer filtration, a suitable length of filter paper 52 is passed through the crossbar 54 and the movable plate 57 and both ends are fixed. The lifting rod 510 moves upward, driving the crossbar 59, the vertical rod 58 and the movable plate 57 to move along the slide groove 55. The slider 56 first rises along the vertical groove to pull the filter paper 52, and then forces the movable plate 57 to flip and deflect through the arc groove, bending the filter paper 52 into a multi-layer overlapping state. When the crossbar 59 moves down to the position, it squeezes the pin 513 to retract. After alignment, the spring 514 pushes the pin 513 into the slot 511 locking mechanism. At this time, the medicine residue is added and the vacuum pump is started, and the medicine liquid can penetrate the multi-layer filter paper 52 to achieve deep filtration.
[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
