Description

Technical Field

[0001] The invention relates to the technical field of oral liquid processing, and in particular to a device for preparing herbal Chinese medicine oral liquid. Background Art

[0002] The main ingredients of herbal oral liquids are typically derived from Chinese medicinal herbs, such as traditional Chinese medicines and plant extracts. The preparation process for herbal oral liquids requires extracting the active ingredients from the raw materials. After extraction, the herbal extracts need to be filtered to remove impurities and suspended solids. Filtration can be performed through pressure filtration, vacuum filtration, or centrifugal filtration. The filtered liquid needs to be concentrated to achieve an appropriate concentration. Finally, an appropriate amount of excipients is added to the concentrated liquid and packaged.

[0003] Reference is made to a Chinese patent document with authorization publication number CN116550003B, which discloses a drug separation and extraction device for the production of isatis root oral liquid. The device includes a reactor for steaming the isatis root, a heater provided on the reactor, a pump body mounted below the sidewall of the reactor, a discharge port provided on the reactor, a sealing plate secured to the discharge port, a separation mechanism for separating isatis root residue, an adjustment mechanism for adjusting the pressing force, and an impurity removal mechanism for absorbing liquid impurities located below the outer side of the reactor. The pressing effect can be enhanced by pressing the residue with a pressing member that moves in relative vertical directions.

[0004] Regarding the above-mentioned related technologies, during the preparation process of herbal Chinese medicine oral liquid, the medicinal residues produced usually contain coarse and fine medicinal residues. When filtering the medicinal residues, the fine filter residues are easy to clog the filter, thereby affecting the filtration efficiency. At the same time, during the process of pressing the medicinal residues, the fine filter residues may pass through the filter under the action of external force, thereby affecting the quality of the solution. Summary of the Invention

[0005] In view of this, the present invention provides a herbal Chinese medicine oral liquid preparation device, which aims to solve the problems of low filtration efficiency and low quality of filtered solution in existing devices.

[0006] In order to solve the above technical problems, the present invention provides a herbal Chinese medicine oral liquid preparation device, including a frame, a support cylinder fixedly connected to the top of the frame, a feed pipe fixedly connected to the top of the support cylinder, a filter cylinder fixedly connected to the inside of the support cylinder, and the filter cylinder is connected to the feed pipe; a pressure filter fine mesh and a fine filter mesh are provided in the filter cylinder, the fine filter mesh is located below the pressure filter fine mesh, the middle of the filter cylinder is slidably connected to the support tube, a coarse filter mesh is provided in the support tube, the coarse filter mesh is located between the pressure filter fine mesh and the fine filter mesh, a liquid outlet is provided on the side wall of the filter cylinder, an overflow port is provided on the side wall of the pressure filter fine mesh, and a liquid outlet channel connected to the liquid outlet is provided in the filter cylinder; a driving mechanism for driving the fine filter mesh to move upward is provided in the filter cylinder, and the support tube can be driven upward when the fine filter mesh moves up.

[0007] By adopting the above technical solution, the coarse filter mesh first filters the medicinal residue and then filters the medicinal residue through the fine filter mesh, so that the medicinal residue is divided into coarse medicinal residue and fine medicinal residue. The two filtrations can initially improve the filtration efficiency of the medicinal residue, and then the fine filter mesh is pushed up and the medicinal residue is pressure filtered. Since the pressure filter fine mesh is located above the coarse medicinal residue, the coarse medicinal residue can filter the fine medicinal residue, thereby reducing the probability of the fine medicinal residue clogging the pressure filter fine mesh. The medicinal liquid after pressure filtration can flow from the overflow port through the liquid outlet channel to the liquid outlet, thereby further reducing the probability of the medicinal residue mixing into the medicinal liquid and improving the quality of the medicinal liquid.

[0008] Optionally, a first block and a second block are connected to the inner wall of the support tube in a transverse sliding manner, the coarse filter screen is arranged between the first block and the second block, the coarse filter screen can pass over the first block, a spring pin is provided on the side wall of the filter press fine screen, a slot adapted to the spring pin is provided on the inner wall of the support tube, and a third block is connected to the bottom of the inner wall of the support tube in a transverse sliding manner, when the fine filter screen moves up, the third block can be pushed to move the support tube up, and after the support tube is connected to the filter press fine screen, the fine filter screen can pass over the third block.

[0009] By adopting the above technical solution, the first block and the second block can temporarily fix the position of the coarse filter screen. When the fine filter screen moves upward, it first abuts against the third block and then pushes the third block to move upward together with the support tube. During the upward movement of the support tube, it can be connected with the filter press fine screen under the action of the spring pin. Then, during the upward movement, the fine filter screen squeezes the third block into the inner wall of the support tube and passes over the third block. The coarse filter screen can pass over the first block. The movement of the fine filter screen and the coarse filter screen can filter the medicinal residue, thereby squeezing out the medicinal liquid in the medicinal residue. After the filter press fine screen is connected to the support tube, the coarse filter screen and the fine filter screen are located in the support tube. When the filter press fine screen is taken out, the coarse filter screen and the fine filter screen can be taken out at the same time, which is conducive to the discharge of the filtered medicinal residue.

[0010] Optionally, the coarse filter includes a support frame, which is arranged between the first block and the second block. A sliding plate is vertically slidably connected above the support frame. A plurality of connecting tubes and extrusion rods are fixedly connected to the top of the support frame. The connecting tubes and the extrusion rods are both slidably connected to the sliding plate, and a first return spring is sleeved on the connecting tubes and the extrusion rods.

[0011] By adopting the above technical solution, since the coarse medicinal residues are large, the gaps between them are too large, and the compression efficiency is low. The setting of the extrusion rod can squeeze the coarse residues, thereby speeding up the speed of squeezing out the medicinal liquid and improving the filtration efficiency.

[0012] Optionally, the coarse filter can pass over the first block when moving up or down, and after the fine filter passes over the second block, the second block can support the fine filter, and the second block and the third block have the same shape.

[0013] By adopting the above technical solution, the coarse filter can squeeze the first block and shrink into the inner wall of the support tube when moving upward or downward. When the coarse filter moves up, it passes over the first block to compress the medicinal residue. When the coarse filter moves downward during installation, it can pass over the first block to preliminarily fix its position. The setting of the second block and the third block enables the fine filter to pass over the second block and the third block, and at the same time can limit and support the position of the fine filter.

[0014] Optionally, the driving mechanism includes a hydraulic cylinder fixedly mounted on the bottom of the filter cartridge, the driving shaft of the hydraulic cylinder is fixedly connected to a support plate, the filter cartridge is fixedly connected to a support column, the support plate is vertically slidably connected to a support ring, the support ring can support the fine filter screen, and the support column can support the support ring.

[0015] By adopting the above technical solution, the setting of the support ring allows for liquid discharge at the bottom of the fine filter. When the hydraulic cylinder drives the fine filter upward, the support ring breaks away from the support of the support column and slides into the interior of the support plate, thereby enabling the fine filter to be evenly forced to move upward. At the same time, the bottom of the fine filter can be sealed to prevent fine drug residue from passing through the fine filter and affecting the quality of the drug liquid.

[0016] Optionally, a second return spring is fixedly connected between the first clamping block, the second clamping block, the third clamping block and the inner wall of the support tube.

[0017] By adopting the above technical solution, the provision of the second return spring can make the first clamping block, the second clamping block and the third clamping block retract into the inner wall of the support tube and then return to their initial state.

[0018] Optionally, the feeding tube is configured to be funnel-shaped.

[0019] By adopting the above technical solution, the funnel-shaped feed pipe is conducive to smoothly guiding the material into the filter barrel, and at the same time can reduce the adhesion and accumulation of the material on the pipe wall, thereby ensuring that the material continuously and stably enters the filter barrel.

[0020] Optionally, an L-shaped chute is provided on the inner wall of the filter cartridge, and a slider capable of sliding in the L-shaped chute is fixedly connected to the side wall of the filter press fine mesh.

[0021] By adopting the above technical solution, the slider can simply fix the filter press fine mesh after sliding in the L-shaped slide groove, which facilitates the removal of the filter press fine mesh in the subsequent process.

[0022] In summary, compared with the prior art, the present invention has at least one of the following beneficial technical effects:

[0023] 1. The two filtrations can separate the medicinal residue into coarse and fine residues, which is beneficial to the filtration of the medicinal liquid, thereby preliminarily improving the filtration efficiency of the medicinal residue. Then the filter residue is pressed, and the fine medicinal residue is located below the coarse medicinal residue. During the upward pressing process, the coarse medicinal residue can filter the fine medicinal residue, thereby reducing the probability of the fine medicinal residue clogging the filter screen and improving the quality of the medicinal liquid.

[0024] 2. The overflow port is set to allow the liquid medicine to flow upward and be collected, thereby reducing the probability of the residue flowing out with the liquid medicine, thereby improving the quality of the liquid medicine;

[0025] 3. During the filter pressing process of the medicinal residue, the support tube can be connected to the filter press fine mesh, the coarse filter mesh is located inside the support tube, and the fine filter mesh can enter the support tube. When the filter press fine mesh is taken out, the coarse filter mesh and the fine filter mesh can be taken out together, which is conducive to the discharge of the medicinal residue.

[0036] Reference Figure 1 and Figure 2 A device for preparing oral liquid of herbal Chinese medicine comprises a frame 1 placed on a horizontal surface, a filtering mechanism for filtering medicinal residue twice, and a filter pressing mechanism for squeezing the filter screen. A support cylinder 11 is fixedly connected to the top of the frame 1, a funnel-shaped feed pipe 12 is fixedly connected to the inner wall of the support cylinder 11, the filtering mechanism and the filter pressing mechanism are both arranged in a filter cylinder 13, the filter cylinder 13 is fixedly connected to the inside of the support cylinder 11, and the filter cylinder 13 and the support cylinder 11 are coaxially arranged. A liquid outlet 131 is opened in the middle of the filter cylinder 13 for the filtered medicinal liquid to flow out, and a liquid outlet pipe 111 is connected to the support cylinder 11 to collect the medicinal liquid.

[0037] Reference Figure 2 and Figure 3The filtering mechanism includes a fine filter screen 15 and a coarse filter screen 17. The coarse filter screen 17 is located above the fine filter screen 15. A plurality of liquid inlets 133 are provided on the side wall of the filter cylinder 13. The medicinal residue raw liquid can enter the filter cylinder 13 through the feed pipe 12 and the liquid inlet 133. A support tube 16 is vertically slidably connected to the filter cylinder 13. A first card block 3 and a second card block 31 are horizontally slidably connected to the support tube 16. The coarse filter screen 17 is located between the first card block 3 and the second card block 31. The fine filter screen 15 is located above the liquid outlet 131.

[0038] When the medicinal residue raw material needs to be filtered, the medicinal residue raw material is introduced into the feed pipe 12, and the medicinal residue is first filtered through the coarse filter 17, so that the coarse medicinal residue accumulates on the coarse filter 17, and then the medicinal residue is filtered again through the fine filter 15. The medicinal liquid passes through the fine filter 15 and flows out from the liquid outlet 131, thereby realizing the preliminary collection of the medicinal liquid.

[0039] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The filter press mechanism includes a driving mechanism 2 for driving the fine filter screen 15 to move upward, a third clamping block 34, a filter press fine filter screen 14, an overflow port 141, and a liquid outlet channel 132. The driving mechanism 2 includes a hydraulic cylinder 21, a support plate 22, a support column 23, and a support ring 24. The hydraulic cylinder 21 is fixedly installed at the bottom of the filter cartridge 13, the support plate 22 is fixedly connected to the driving shaft of the hydraulic cylinder 21, the support column 23 is fixedly connected to the bottom wall inside the filter cartridge 13, and the support ring 24 is slidably connected to the support plate 22. The support ring 24 can support the fine filter screen 15 and leave a gap between the fine filter screen 15 and the support plate 22 to facilitate the outflow of the liquid medicine. The support column 23 can support the support ring 24. The support is performed so that the top of the support ring 24 extends out of the support plate 22, and the third block 34 is horizontally slidably connected to the inner wall of the support tube 16. The third block 34 and the second block 31 are both configured as trapezoidal blocks. A gap is left between the support plate 22 and the filter cartridge 13 to facilitate the support plate 22 to pass over the third block 34. The first block 3, the second block 31, and the third block 34 are all fixedly connected to the inner wall of the support tube 16 with a second reset spring to facilitate the reset of the first block 3, the second block 31, and the third block 34.

[0040] Reference Figure 6 and Figure 7 An L-shaped chute 4 is provided on the inner wall of the filter cartridge 13, and a slider 41 which can be in the L-shaped chute 4 is fixedly connected to the side wall of the filter press fine mesh 14. The filter press fine mesh 14 can be installed in the filter cartridge 13 by sliding the slider 41 in the L-shaped chute 4.

[0041] Reference Figure 4 、 Figure 6 and Figure 7A card slot 33 is provided on the inner wall of the support tube 16, and a spring pin 32 that cooperates with the card slot 33 is provided on the outer wall of the filter press fine mesh 14. The filter press fine mesh 14 is arranged at the top of the filter cartridge 13, and the overflow port 141 is provided on the top side wall of the filter press fine mesh 14 to facilitate the outflow of the liquid through the filter press fine mesh 14. The liquid outlet channel 132 is provided on the inner wall of the filter cartridge 13, and the liquid flowing out of the overflow port 141 can flow into the liquid outlet channel 132 and flow from the liquid outlet channel 132 to the liquid outlet 131. The top of the filter cartridge 13 is detachably connected with an end cover 134.

[0042] When the coarse filter 17 moves upward or downward, it can squeeze the first block 3 and retract it into the inner wall of the support tube 16, so that the coarse filter 17 can pass over the first block 3, which is beneficial to the installation of the coarse filter 17 and can also move the coarse filter 17 to squeeze the coarse medicinal residue. The fine filter 15 can squeeze and pass over the second block 31 and the third block 34 when moving upward, but the second block 31 and the third block 34 can support the coarse filter 17 or the fine filter 15 to achieve the limitation of the coarse filter 17 or the fine filter 15.

[0043] Reference Figure 3 and Figure 8 The coarse filter 17 includes a support frame 171, a sliding plate 172, a connecting pipe 173, an extrusion rod 174, and a first return spring 175. The support frame 171 is located between the first clamping block 3 and the second clamping block 31 and is configured as a cylinder. The connecting pipe 173 and the extrusion rod 174 are both fixedly connected to the inner bottom wall of the support frame 171. The sliding plate 172 is sleeved on the side walls of the connecting pipe 173 and the extrusion rod 174. The first return spring 175 is sleeved on the connecting pipe 173 and the extrusion rod 174 and is fixedly connected between the sliding plate 172 and the support frame 171. Since the coarse medicinal residue is relatively large in volume, the pounding of the material by the extrusion rod 174 can enhance the extrusion effect of the coarse medicinal residue, thereby improving work efficiency.

[0044] When it is necessary to filter the medicinal residue, the hydraulic cylinder 21 is started to drive the support plate 22 to move upward. During the upward movement of the support plate 22, the support column 23 can be separated. As the support plate 22 continues to move, the support ring 24 enters the support plate 22, and then the support plate 22 pushes the fine filter screen 15 to move upward. At this time, the support plate 22 fits the fine filter screen 15 to prevent leakage of the medicinal liquid and fine medicinal residue. During the upward movement of the fine filter screen 15, it will abut against the third block 34, and then push the third block 34 to make the support tube 16 move upward. As the support tube 16 moves upward, the support tube 16 is connected to the filter press fine mesh 14 under the action of the spring pin 32 and the card slot 33, thereby limiting the upward movement of the support tube 16. The support plate 22 continues to push the fine filter screen 15, causing the fine filter screen 15 to pass over the third block 34, and then the medicinal residue is squeezed under the action of the fine filter screen 15, the coarse filter screen 17 and the filter press fine mesh 14, so that the medicinal liquid passes through the filter press fine mesh 14 and overflows from the overflow port 141. The overflowed medicinal liquid enters the liquid outlet channel 132 and then flows out from the liquid outlet 131.

[0045] The filter press fine mesh 14 is connected to the support rod tube, and the coarse filter mesh 17 and the fine filter mesh 15 are both located in the support tube 16. When the filter press fine mesh 14 is taken out, the coarse medicinal residue between the filter press fine mesh 14 and the coarse filter mesh 17 and the fine medicinal residue between the coarse filter mesh 17 and the fine filter mesh 15 can be taken out, which is conducive to the discharge of the medicinal residue.

[0046] The implementation principle of the herbal Chinese medicine oral liquid preparation device of the embodiment of the present invention is: first, the medicinal residue raw material is poured into the feed pipe 12, and the medicinal residue raw material passes through the coarse filter 17 and the fine filter 15 in turn, and the coarse medicinal residue remains on the coarse filter 17, and the fine medicinal residue remains on the fine filter 15. The filtered medicinal liquid flows from the liquid outlet 131 into the support cylinder 11, and then the medicinal liquid flows out from the liquid outlet pipe 111 and is collected.

[0047] The hydraulic cylinder 21 is started to drive the fine filter screen 15 to move upward. The upward movement of the fine filter screen 15 can squeeze the fine medicinal residue. Then, when the fine medicinal residue pushes the coarse filter screen 17 upward, the coarse filter screen 17 moves upward to squeeze the coarse medicinal residue. With the support of the filter press fine screen 14, the medicinal liquid in the coarse medicinal residue and the fine medicinal residue passes through the filter press fine screen 14, and then the medicinal liquid flows out from the overflow port 141 and flows to the liquid outlet 131 through the liquid outlet channel 132.

[0048] During the process of filter pressing the medicinal residue, the support tube 16 can be connected to the filter press fine mesh 14, the coarse filter mesh 17 is located inside the support tube 16, and the fine filter mesh 15 can enter the support tube 16. When the filter press fine mesh 14 is taken out, the coarse filter mesh 17 and the fine filter mesh 15 can be taken out together, which is conducive to the discharge of the medicinal residue.

[0049] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0050] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
