Technical Field

[0001] This utility model relates to the field of plant extraction technology, and in particular to a solid-liquid separation device for extracting medicinal plants. Background Technology

[0002] Medicinal plants, as the name suggests, refer to plant species that possess medicinal properties. A key step in extracting the active ingredients from these plants is using specialized solid-liquid separation equipment to effectively separate the liquid components (commonly known as "sap") from the plant through methods such as pressing.

[0003] Most existing separation devices are large in size, require a large amount of open space, or have a complex structure and operation method, making them inconvenient to use and causing high and cumbersome subsequent maintenance and cleaning costs. Summary of the Invention

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as large size, large space occupation, or complex structure and operation, which are inconvenient to use and result in high and cumbersome subsequent maintenance and cleaning costs. Therefore, a solid-liquid separation device for extracting medicinal plants is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A solid-liquid separation device for extracting medicinal plants includes a main shell, an inlet on one side of the outer wall of the main shell, an upper half-ring plate hinged inside the inlet, a discharge port on one side of the outer wall of the main shell, a lower half-ring plate inserted inside the discharge port, and a liquid outlet pipe fixedly connected to the bottom of the outer wall of the main shell.

[0007] A pressure plate, used for pressing plants, is slidably disposed inside the main shell;

[0008] A filter plate is used to filter the pressed liquid. The inner wall of the main shell has a concave surface, and the filter plate is inserted into the concave surface. The filter plate is fixedly installed on the inner wall of the lower half ring plate.

[0009] A limiting component is used to limit and fix the lower half ring plate and the upper half ring plate, and the limiting component is disposed on the outer wall of the main shell.

[0010] In one possible design, a hydraulic cylinder is fixedly installed on the top inner wall of the main housing, and the bottom end of the piston rod of the hydraulic cylinder is fixedly installed on the top of the pressure plate.

[0011] In one possible design, a fixing plate is fixedly installed on the inner wall of the main housing, and the fixing plate is fixedly sleeved on the outer wall of the hydraulic cylinder.

[0012] In one possible design, the limiting component includes a limiting semi-ring that is slidably sleeved on the outer wall of the main shell, and the limiting semi-ring cooperates with the lower semi-ring plate and the upper semi-ring plate.

[0013] In one possible design, the limiting assembly further includes an outer rod, a lower fixing block is fixedly disposed on the outer wall of the limiting semi-ring, an upper fixing block is fixedly disposed on the outer wall of the main shell, the outer rod is fixedly disposed on the top of the lower fixing block, and the top end of the outer rod slides through the upper fixing block. A sliding cavity is opened inside the outer rod, and an inner plate is slidably disposed inside the sliding cavity. A pressing block, an upper limit block, and a lower limit block are fixedly disposed on one side of the inner plate, and one end of the pressing block, the upper limit block, and the lower limit block slides through to the outside of the outer rod. The upper limit block and the lower limit block are respectively attached to the top and bottom of the upper fixing block.

[0014] In one possible design, the inner plate is provided with multiple compression springs, with the two ends of the compression springs fixedly disposed on one side of the inner plate and the inner wall of one side of the sliding cavity, respectively.

[0015] In one possible design, a plurality of support rods are fixedly provided on the bottom inner wall of the main shell, and the top ends of the plurality of support rods are all in contact with the bottom of the filter plate.

[0016] In this application, during actual use, pressing the pressing block causes it to move the upper and lower limit blocks via the inner plate, retracting them into the outer rod. The outer rod can then be moved to move the limiting half-ring up and down. First, the limiting half-ring is moved downwards to release its restriction on the upper half-ring plate, allowing the upper half-ring plate to open. The medicinal plant is then placed into the main shell through the feed inlet. The upper half-ring plate and the limiting half-ring are then reset. The hydraulic cylinder is then driven to move the pressure plate downwards, pressing the plant against the filter plate below to extract juice. The juice is discharged through the outlet pipe. When the pressed plant residue needs to be removed, the fixing of the limiting half-ring is released in the same way. Then, the limiting half-ring is moved upwards to release its restriction on the lower half-ring plate, allowing the lower half-ring plate to be pulled out. The plant residue is then removed via the filter plate, completing the entire process.

[0017] In this utility model, the solid-liquid separation device for extracting medicinal plants can press the medicinal plants through a pressure plate and a filter plate, and can quickly and evenly apply pressure to effectively extract the liquid components from the medicinal plants. The design of the filter plate ensures that the pressed liquid can pass through smoothly, while preventing solid impurities from entering, thus achieving efficient solid-liquid separation.

[0018] In this utility model, the solid-liquid separation device for extracting medicinal plants can limit and fix the lower half ring plate and the upper half ring plate through the limiting component. When it is necessary to release the limiting state and open, it is only necessary to control the limiting half ring to make the corresponding displacement to achieve the release. The operation is simple and convenient.

[0019] The separation device of this invention has the advantages of small footprint, simple structure and convenient operation, low initial cost and low subsequent maintenance cost. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0026] Reference Figure 1 A solid-liquid separation device includes: a main shell 1, a pressure plate 10, a filter plate 11, and a limiting component.

[0027] The main shell 1 serves as the core structure of the entire device. A feed inlet 7 is located on one side of its outer wall for adding the medicinal plants to be pressed. An upper ring plate 6 is hinged inside the feed inlet 7, allowing it to be opened or closed. A discharge port 8 is also located on one side of the main shell 1 for discharging solid waste after pressing. A lower ring plate 5 is inserted inside the discharge port 8, also allowing it to be opened or closed. Handles or other auxiliary components can be added to the surfaces of the upper and lower ring plates 6 and 5 to facilitate opening. A liquid outlet pipe 4 is fixedly connected to the bottom of the main shell 1's outer wall for discharging the pressed liquid.

[0028] Reference Figure 2 The press plate 10 is used to press the plant and is slidably disposed inside the main shell 1. When the press plate 10 moves downward, it presses the medicinal plant placed on the filter plate 11, thereby separating the liquid.

[0029] The filter plate 11 is used to filter the pressed liquid, ensuring that the liquid does not contain solid impurities. A concave surface 12 is provided on the inner wall of the main shell 1, and the filter plate 11 is inserted into the concave surface 12 and fixedly mounted on the inner wall of the lower half-ring plate 5. Thus, when the lower half-ring plate 5 closes the discharge port 8, the filter plate 11 is also fixed, ensuring the stability of the filter plate 11 during the pressing process. To prevent solid impurities from falling off when the filter plate 11 is removed, an arc-shaped protective plate can be installed at the top edge of the filter plate 11.

[0030] Furthermore, a hydraulic cylinder 2 is fixedly installed on the top inner wall of the main shell 1, and the bottom end of the piston rod of the hydraulic cylinder 2 is fixedly installed on the top of the pressure plate 10. By controlling the extension and retraction of the hydraulic cylinder 2, the pressure plate 10 can be driven to move up and down, thereby realizing the pressing of medicinal plants.

[0031] To ensure the stability of the hydraulic cylinder 2, a fixing plate 9 is fixedly installed on the inner wall of the main housing 1, and the fixing plate 9 is fixedly sleeved on the outer wall of the hydraulic cylinder 2. In this way, the hydraulic cylinder 2 will be more stable during the extension and retraction process and will not shake.

[0032] This application can be used in the field of plant extraction, or in other fields applicable to this application. Example 2

[0033] refer to Figure 3-4 An improvement upon Example 1: A solid-liquid separation device for medicinal plant extraction, applied in the field of plant extraction, wherein a limiting component is used to limit and fix the lower half-ring plate 5 and the upper half-ring plate 6 to prevent them from accidentally opening during the pressing process. The limiting component is located on the outer wall of the main shell 1.

[0034] The specific structure of the limiting assembly includes a limiting semi-ring 3, an outer rod 17, a lower fixing block 14, an upper fixing block 15, an inner plate 16, a pressing block 18, an upper limiting block 20, and a lower limiting block 21. The limiting semi-ring 3 is slidably sleeved on the outer wall of the main shell 1 and cooperates with the lower semi-ring plate 5 and the upper semi-ring plate 6. When it is necessary to fix the lower semi-ring plate 5 or the upper semi-ring plate 6, simply slide the limiting semi-ring 3 to the corresponding position.

[0035] The outer rod 17 is fixedly mounted on the top of the lower fixed block 14, and the top end of the outer rod 17 slides through the upper fixed block 15. A sliding cavity 22 is provided inside the outer rod 17, and an inner plate 16 is slidably mounted inside the sliding cavity 22. A pressing block 18, an upper limit block 20, and a lower limit block 21 are fixedly mounted on one side of the inner plate 16.

[0036] Specifically, pressing down on the pressing block 18 causes it to move the upper limit block 20 and lower limit block 21 via the inner plate 16, retracting them into the outer rod 17. At this point, the outer rod 17 can be moved to move the limiting half-ring 3 up and down. First, the limiting half-ring 3 is moved downwards to release its restriction on the upper half-ring plate 6. Then, the upper half-ring plate 6 can be opened, and the medicinal plant can be placed into the main shell 1 through the feed inlet 7. Afterwards, the upper half-ring plate 6 and the limiting half-ring 3 are reset, and then the plant can be driven... The hydraulic cylinder 2 drives the pressure plate 10 to move downwards. The pressure plate 10 causes the plant to be squeezed against the filter plate 11 below, thereby extracting juice. The juice is discharged through the outlet pipe 4. When it is necessary to remove the plant residue after pressing, the fixing of the limiting half ring 3 is released in the same way. Then, the limiting half ring 3 is moved upwards to release the limitation on the lower half ring plate 5. At this time, the lower half ring plate 5 can be pulled out. The plant residue is removed by the lower half ring plate 5 through the filter plate 11, thus completing the whole process.

[0037] To increase the stability of the inner plate 16, multiple compression springs 19 are also provided inside the inner plate 16. The two ends of the compression springs 19 are fixedly installed on one side of the inner plate 16 and one side of the inner wall of the sliding cavity 22, respectively. In this way, when the pressing block 18 is released, the compression springs 19 will push the inner plate 16 to reset, thereby ensuring the reliability of the limiting assembly.

[0038] In addition, multiple support rods 13 are fixedly installed on the bottom inner wall of the main shell 1. The top ends of the multiple support rods 13 are all in contact with the bottom of the filter plate 11. In this way, during the pressing process, the filter plate 11 will be supported by the support rods 13, thus being more stably fixed inside the concave surface 12.

[0039] It has the advantages of small footprint, simple structure and easy operation, low initial cost and low subsequent maintenance cost.

[0040] However, as is well known to those skilled in the art, the working principle and wiring method of the hydraulic cylinder 2 are commonplace and are all conventional means or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
