Description

Technical Field

[0001] This utility model relates to the field of extract filtration, and in particular to a filtration device for natural plant extracts. Background Technology

[0002] Plant extraction filtration is a key process for separating solid residues from active ingredients, which directly determines product purity and production efficiency. After solvent extraction, plant raw materials (such as roots, leaves, and fruits) contain a large number of suspended particles and colloids (such as pectin and starch). Filtration removes large particulate impurities from the mixture.

[0003] To efficiently filter and separate the active ingredients in plant extracts, the solid residue is extruded. The active ingredients in the solid residue are first separated by extrusion, and then filtered to obtain more of the active ingredients from the plant extract. Utility Model Content

[0004] In view of this, the present invention provides a filtration device for natural plant extraction, the main technical problem to be solved is: by first squeezing and then filtering, more effective components can be obtained from the solid residue.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a filtration device for natural plant extraction, comprising a base, a first support plate fixedly connected to the inner wall of the base, a first filter plate mounted on the first support plate, a first through hole being formed on the surface of the first filter plate, the number of the first through holes being multiple, a second support plate fixedly connected to the inner wall of the base, a pressing frame mounted on the second support plate, a second through hole being formed on the surface of the pressing frame, the number of the second through holes being multiple, a top frame mounted on the top of the base, a cylinder fixedly connected to the lower surface of the top frame, a pressure plate fixedly connected to the bottom of the cylinder, and the pressure plate being located directly above the pressing frame.

[0006] By adopting the above technical solution, when in use, the plant raw materials that have been soaked in solvent are placed into the extrusion frame. The pressure plate is moved downward by the operation of the cylinder to extrude the plant raw materials in the extrusion frame. After being compressed, the effective components inside the plant raw materials are discharged along with the solvent, while the solid residue remains in the extrusion frame. The solvent containing the effective components passes through the second through hole on the extrusion frame to reach the first filter plate. Then, the solvent passes through the first filter plate for primary filtration, which can effectively separate the small particulate solid residue in the solvent.

[0007] As a further description of the above technical solution:

[0008] The upper surface of the first filter plate is equipped with support bars, and there are multiple support bars. The bottom of the extrusion frame is in contact with the upper surface of the support bars.

[0009] By adopting the above technical solution, the bottom of the extrusion frame can be supported by the support strip, which facilitates the extrusion plate to extrude the plant material inside the extrusion frame. At the same time, the support strip can create a gap between the extrusion frame and the first filter plate, which allows the solvent to pass through the first filter plate.

[0010] As a further description of the above technical solution:

[0011] The lower surface of the first filter plate is fixedly connected with a fixing strip, and there are multiple fixing strips.

[0012] By adopting the above technical solution, the strength of the first filter plate can be increased by the fixing strip, making the first filter plate easier to use.

[0013] As a further description of the above technical solution:

[0014] A third support plate is fixedly connected to the inner wall of the base, and a second filter plate is installed on the third support plate.

[0015] By adopting the above technical solution, the solvent after primary filtration can be filtered in a secondary manner through the second filter plate, which facilitates the removal of impurities such as colloids from the solvent.

[0016] As a further description of the above technical solution:

[0017] The second filter plate is inclined and is located below the first filter plate.

[0018] By adopting the above technical solution, the impurities filtered by the second filter plate will slide down the second filter plate and be discharged at the baffle.

[0019] As a further description of the above technical solution:

[0020] The base has an outlet on its side wall, and a baffle is movably connected inside the outlet. The position of the baffle corresponds to the bottom position of the second filter plate.

[0021] By adopting the above technical solution, opening the baffle can remove impurities from the surface of the second filter plate.

[0022] As a further description of the above technical solution:

[0023] A discharge pipe is installed on the side wall of the base, and the discharge pipe is located below the second filter plate.

[0024] By adopting the above technical solution, the solvent after multiple filtrations can be discharged through the discharge pipe.

[0025] By employing the above technical solution, the filtration device for natural plant extraction of this utility model has at least the following beneficial effects:

[0026] Compared with existing technologies, this natural plant extraction filtration device places the plant material, which has been treated with solvent soaking, into a squeezing frame. The cylinder controls the pressure plate to move downward, squeezing the plant material in the squeezing frame. After being squeezed, the effective components inside the plant material are discharged along with the solvent, while the solid residue remains in the squeezing frame. The solvent containing the effective components passes through the second through hole on the squeezing frame to reach the first filter plate. The solvent then passes through the first filter plate for primary filtration, which can effectively separate small particulate solid residues from the solvent. Attached Figure Description

A second support plate 7 fixedly connected to the inner wall of the base 1, and a compression frame 8 mounted on the second support plate 7, are used to compress and filter plant materials that have undergone solvent soaking. Multiple second through holes 9 are provided on the surface of the compression frame 8. A top frame 10 is mounted on the top of the base 1. A cylinder 11 is fixedly connected to the surface, and a pressure plate 12 is fixedly connected to the bottom of the cylinder 11. The operation of the cylinder 11 controls the up and down movement of the pressure plate 12. The pressure plate 12 is located directly above the extrusion frame 8. In use, the plant material that has been soaked in solvent is placed into the extrusion frame 8. The operation of the cylinder 11 controls the pressure plate 12 to move downward, extruding the plant material in the extrusion frame 8. After the plant material is compressed, the effective components inside will be discharged along with the solvent. The solid residue will remain in the extrusion frame 8. The solvent containing the effective components will pass through the second through hole 9 on the extrusion frame 8 to reach the first filter plate 3. Then the solvent passes through the first filter plate 3 for primary filtration, which can effectively separate small particulate solid residues in the solvent.

[0034] The upper surface of the first filter plate 3 is equipped with support bars 5, and there are multiple support bars 5. The bottom of the extrusion frame 8 is in contact with the upper surface of the support bars 5. The support bars 5 can support the bottom of the extrusion frame 8, which makes it easier for the pressure plate 12 to extrude the plant material inside the extrusion frame 8. At the same time, the support bars 5 can create a gap between the extrusion frame 8 and the first filter plate 3, which allows the solvent to pass through the first filter plate 3. The lower surface of the first filter plate 3 is fixedly connected with fixing bars 4, and there are multiple fixing bars 4. The fixing bars 4 can increase the strength of the first filter plate 3 and make it easier to use the first filter plate 3.

[0035] A third support plate 13 is fixedly connected to the inner wall of the base 1. A second filter plate 14 is installed on the third support plate 13. The solvent after primary filtration can be filtered in a secondary manner through the second filter plate 14, which facilitates the removal of impurities such as colloids in the solvent. The second filter plate 14 is inclined and located below the first filter plate 3. The impurities filtered by the second filter plate 14 will slide down the second filter plate 14 and be discharged at the baffle 15.

[0036] The base 1 has an outlet on its side wall, and a baffle 15 is movably connected inside the outlet. The position of the baffle 15 corresponds to the bottom position of the second filter plate 14. Opening the baffle 15 can treat the impurities on the surface of the second filter plate 14. A discharge pipe 16 is installed on the side wall of the base 1. The discharge pipe 16 is located below the second filter plate 14. The solvent after multiple filtrations can be discharged through the discharge pipe 16.

[0037] Working principle: When in use, the plant material that has been soaked in solvent is placed into the extrusion frame 8. The cylinder 11 controls the pressure plate 12 to move downward, extruding the plant material in the extrusion frame 8. After being compressed, the effective components inside the plant material are discharged along with the solvent, while the solid residue remains in the extrusion frame 8. The solvent containing the effective components passes through the second through hole 9 on the extrusion frame 8 to reach the first filter plate 3. The solvent then passes through the first filter plate 3 for primary filtration, which can effectively separate small particulate solid residues in the solvent.
