Description

Technical Field

[0001] The invention relates to the field of plant extraction, and in particular to a plant extraction impurity separation device. Background Art

[0002] Plant extraction generally involves putting plant materials into a filter cartridge, and then applying mechanical pressure to the plant materials inside the filter cartridge to rupture the cells, thereby squeezing out the active ingredients in the cells and passing them through the filter cartridge. This method is simple and easy, with relatively low cost. For some active ingredients that are unstable to heat, it can avoid damage caused by high temperature, and better maintain the original aroma and activity of the plant materials.

[0003] However, during the plant extraction process, great pressure needs to be applied to the plant raw materials, which will cause the impurities to be squeezed too tightly with the filter cartridge when the subsequent plant residues (impurities) are separated from the device, making it difficult to quickly separate the impurities from the device, affecting subsequent plant extraction operations.

DETAILED DESCRIPTION

[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] The present invention provides Figure 1-Figure 15 The plant extraction impurity separation device shown in the figure comprises: an upper shell 2, a controller 5 is installed on the outside of the upper shell 2, a support plate 23 is fixed to the bottom of the inner part of the upper shell 2, a limit plate 20 is fixed to the inner part of the upper shell 2 above one side of the support plate 23, and a knife holder 22 for cutting plant raw materials is slidably connected between the support plate 23 and the limit plate 20 through a slide groove;

[0047] Support frame 1, support frame 1 is fixed on the top of support plate 23, and a motor 15 is installed on the top of support frame 1, the output shaft of motor 15 penetrates into the inside of support frame 1, the top of support plate 23 is slidably connected with a top block 21 for pushing plant material toward the knife holder 22 through a slide rail on the side facing the knife holder 22, the top block 21 penetrates support frame 1, and the motor 15 drives the top block 21 to do reciprocating motion through a reciprocating mechanism;

[0048] The lower shell 6 is fixed to the bottom of the upper shell 2. A lower air guide cover 14 and an upper air guide cover 19 are fixed inside the lower shell 6. The top opening of the upper air guide cover 19 is located on one side of the tool holder 22. The bottom opening of the upper air guide cover 19 is communicated with the top opening of the lower air guide cover 14. A filter cartridge 40 for primary filtration of plant juice is threadedly connected to the bottom opening of the lower air guide cover 14. The external thread of the filter cartridge 40 is threadedly connected to the connecting cylinder 13. A sealing mechanism is provided at the bottom of the connecting cylinder 13, and a filtering mechanism for secondary filtration of plant juice is provided on one side of the connecting cylinder 13.

[0049] The limiting tube 24 is fixed on the top of the lower air guide cover 14. A pressure column 38 for squeezing the divided plant material is arranged inside the limiting tube 24. The bottom end of the pressure column 38 passes through the interior of the lower air guide cover 14. The diameter of the pressure column 38 matches the inner diameter of the filter cartridge 40. Two sets of lifting components are arranged on the output shaft of the motor 15, and one set of lifting components is used to control the lifting process of the pressure column 38.

[0050] Furthermore, the knife holder 22 includes a rectangular frame and a pull plate, the rectangular frame is slidably connected to the support plate 23 and the limit plate 20 through a slide rail, and a plurality of blades are fixed in a crisscross manner inside the rectangular frame, the pull plate is fixed to one side of the rectangular frame, one end of the rectangular frame passes through the lower shell 6, and the pull plate is fixedly connected to the upper shell 2 by bolts. In order to improve the sealing between the pull plate and the upper shell 2, a sealing gasket can be installed at the junction of the pull plate and the upper shell 2. The specific structure of the knife holder 22 can be referred to the attached manual. Figure 7 , since it is a conventional technology, only the general structure is briefly introduced here.

[0051] Furthermore, a feed box 3 is fixed to the top of the limiting plate 20, and a box cover is rotatably connected to the top of the feed box 3 via a rotating shaft, and a guide plate is provided inside the feed box 3 to guide the plant raw materials to between the tool holder 22 and the top block 21. The feed box 3 can more easily feed the plant raw materials to between the tool holder 22 and the top block 21.

[0052] Furthermore, the filtering mechanism includes a filter 7 , a liquid inlet end of the filter 7 is connected to the connecting cylinder 13 through a pipeline, and a liquid outlet end of the filter 7 is connected to a liquid collecting cylinder 8 through a pipeline, and the liquid collecting cylinder 8 is located inside the lower shell 6 .

[0053] Furthermore, the reciprocating mechanism includes a driving wheel 31 and a driven wheel 30, the driving wheel 31 is mounted at the bottom end of the output shaft of the motor 15, the driven wheel 30 is mounted on the top of the support plate 23 through a bearing, the driving wheel 31 is meshed and connected with the driven wheel 30, a connecting rod 32 is fixed to the top of the driven wheel 30 near its edge, a connecting arm 33 is provided between the connecting rod 32 and the top block 21, the connecting arm 33 is rotatably connected to the connecting rod 32 through a bearing, and the connecting arm 33 is rotatably connected to the top block 21 through a rotating seat. When the plant material enters between the tool holder 22 and the top block 21, the controller The motor 15 drives the driving wheel 31 to rotate, and then the driving wheel 31 drives the driven wheel 30 to rotate, and the top block 21 can be moved back and forth in cooperation with the connecting rod 32 and the connecting arm 33. When the top block 21 moves toward the knife holder 22, the plant material can be pushed toward the knife holder 22 and squeezed, so that the plant material is forcibly cut into "small pieces" by the blade on the knife holder 22. When the top block 21 moves away from the knife holder 22, the distance between the top block 21 and the knife holder 22 becomes larger, so that the plant material falls back between the top block 21 and the knife holder 22, so as to cut the plant material again. (During the movement of the top block 21, the end of the top block 21 away from the knife holder 22 will never move out of the support frame 1 to prevent the plant material from entering the interior of the support frame 1. Considering the sealing problem between the support frame 1 and the top block 21, since the plant material is not completely crushed during cutting, the sealing requirements between the support frame 1 and the top block 21 can be appropriately reduced).

[0054] Furthermore, the two lifting assemblies include a turntable 36, which is fixed on the output shaft of the motor 15 in an inclined state, and U-shaped connecting frames 41 are arranged on both sides of the turntable 36, and the edges of both sides of the turntable 36 extend to the inside of the two U-shaped connecting frames 41, and the inner top and inner bottom of the U-shaped connecting frame 41 are installed with balls 42;

[0055] The bottom of one of the U-shaped connecting frames 41 is connected to a lower movable rod 35, and the bottom end of the lower movable rod 35 is connected to a pressure column 38;

[0056] The top of the other U-shaped connecting frame 41 is connected to the upper movable rod 34 .

[0057] When the output shaft of the motor 15 rotates, the turntable 36 is driven to rotate. Since the turntable 36 is in an inclined state, the U-shaped connecting frame 41 is driven to move up and down during the rotation of the turntable 36, thereby driving the upper movable rod 34 and the lower movable rod 35 to move up and down as a whole;

[0058] When the lower movable rod 35 moves downward, it drives the pressing column 38 to move toward the inside of the filter cartridge 40, thereby squeezing the segmented plant material inside the filter cartridge 40 (in the actual process, the depth of the pressing column 38 entering the filter cartridge 40 will not be too deep, and the pressing column 38 can be controlled to extend into one fifth of the filter cartridge 40 to prevent the pressing column 38 from occupying too much space in the filter cartridge 40);

[0059] After the lower movable rod 35 drives the pressure column 38 to move upward and separate from the filter cartridge 40, the plant material cut inside the lower guide cover 14 will enter the filter cartridge 40 again, and the cut plant material will be forced to be squeezed to achieve the "juice extraction" operation. The specific structure of the lower guide cover 14 is shown in the attached manual. Figure 8 As shown, its own structure will "guide" the cut plant material to the inside of the filter cartridge 40;

[0060] During the "juicing" operation, the plant juice will pass through the filter cartridge 40 to complete the preliminary filtration of the plant juice, and then the preliminary plant juice will enter the interior of the connecting cylinder 13, and then enter the filter 7 through the pipeline. After being filtered by the filter 7, a purer plant juice is obtained and finally stored in the liquid collecting cylinder 8, while the plant residue part or the impurities on the surface of the plant are located in the filter cartridge 40 and the filter 7. (The plant residue and impurities inside the filter cartridge 40 account for the main part, and the filter 7 accounts for a small part. The filter 7 in the present invention is actually a very conventional liquid filter in the prior art. Common household drinking water filters in reality can be used as the filter 7 in the present invention).

[0061] Furthermore, the sealing mechanism includes a connecting ring 12 and a support tray 11, the connecting ring 12 is fixed to the outer bottom of the connecting tube 13, the support tray 11 is located below the connecting ring 12, and a circular bottom plate 48 that can move up and down is arranged inside the support tray 11, the diameter of the circular bottom plate 48 is the same as the diameter of the filter tube 40, and a pressure sensor 49 for monitoring the pressure of the circular bottom plate 48 is installed at the bottom of the circular bottom plate 48 inside the support tray 11, and an electric lifting rod 10 is installed inside the lower shell 6, and the lifting end of the electric lifting rod 10 is connected to the support tray 11 through a bracket.

[0062] Refer to the attached instructions for reference Fig.12 As shown, the bottom of the filter cartridge 40 is in an open state. The advantage of such a setting is that after the "juice extraction" operation is completed, the "columnar" plant residues inside the filter cartridge 40 can be "discharged";

[0063] During the "juicing" operation, the circular bottom plate 48 will be blocked at the bottom of the filter cartridge 40. When the plant is "juicing" inside the filter cartridge 40, the pressure on the plant will be transmitted to the circular bottom plate 48. At this time, the pressure on the plant can be observed in real time through the pressure sensor 49 (this value can refer to the pressure range of the filter cartridge 40 to avoid damage to the filter cartridge 40, or in the actual process, gradually adjust the pressure value to set the pressure at the pressure when most of the "juice" of the plant inside the filter cartridge 40 is squeezed out). When the pressure reaches a certain value, the working process of the motor 15 is stopped, and then the discharge mechanism is started to discharge the columnar plant residue inside the filter cartridge 40. (During the "juicing" operation, the sealing between the connecting ring 12 and the support tray 11 and the sealing between the circular bottom plate 48 and the support tray 11 can be sealed with a sealing rubber ring to prevent "leakage". In the present invention, the electric lifting rod 10 is selected with strong pressure bearing capacity, or a hydraulic rod is used instead. The motor 15 uses a motor with low speed but high torque to provide better power output).

[0064] Specifically, a discharge mechanism for discharging the filter cartridge 40 is provided inside the pressure column 38;

[0065] The discharging mechanism includes a discharging execution component and a power output component for providing power to the discharging execution component;

[0066] The discharge execution component includes a cylindrical groove 45 and a pressure plate 39. The cylindrical groove 45 is opened inside the pressure column 38. The pressure plate 39 is located at the bottom of the pressure column 38. A lower piston 44 that can move up and down is arranged inside the cylindrical groove 45. The bottom of the lower piston 44 is connected to a push rod 46. The top of the push rod 46 is connected to the lower piston 44. The bottom end of the push rod 46 passes through the pressure plate 39, and the bottom end of the push rod 46 is connected to the pressure plate 39. The outside of the push rod 46 is located at the bottom of the lower piston 44 and is sleeved with a spring 47.

[0067] Specifically, the power output assembly includes an air box 16 and an air cylinder 17, and both the air box 16 and the air cylinder 17 are fixed on the top of the support frame 1;

[0068] An upper piston 53 that can move up and down is arranged inside the air cylinder 17, the top end of the upper movable rod 34 passes through the top of the support frame 1, and the top end of the upper movable rod 34 extends to the inside of the air cylinder 17 and is connected to the upper piston 53, the top end of the air cylinder 17 is connected to an air inlet pipe 54, and an air inlet check valve 51 is installed on the air inlet pipe 54, and an air guide pipe 50 is connected to one side of the air cylinder 17 near the top position thereof, and an air outlet check valve 52 is installed on the air guide pipe 50, and the end of the air guide pipe 50 is connected to the air box 16;

[0069] The outside of the air box 16 is connected to a pressure relief pipe 25, on which a pressure relief solenoid valve 29 is installed, and the outside of the air box 16 is installed with a pressure gauge 27 for monitoring the internal air pressure;

[0070] The top of the pressure column 38 is threadedly connected to the connecting air hood 37, an injection pipe 43 is connected between the connecting air hood 37 and the air box 16, and an electromagnetic three-way valve 28 is installed between the injection pipe 43 and the air box 16, wherein two channels of the electromagnetic three-way valve 28 are connected to the injection pipe 43 and the air box 16 respectively, and the remaining channel of the electromagnetic three-way valve 28 is connected to the exhaust pipe 4.

[0071] When the upper movable rod 34 moves upward, it will simultaneously drive the upper piston 53 to move toward the top of the inner part of the air cylinder 17. Since the gas cannot be discharged through the inlet check valve 51, the air will enter the inner part of the air box 16 through the outlet check valve 52 and the air guide pipe 50 and be compressed.

[0072] When the upper movable rod 34 moves downward, it will also synchronously drive the upper piston 53 to move toward the lower part of the inner part of the cylinder 17. At this time, the air in the external environment will be forcibly drawn into the inner part of the cylinder 17 through the air intake check valve 51.

[0073] Since the gas outlet check valve 52 cannot allow the gas inside the gas box 16 to be discharged, and when the electromagnetic three-way valve 28 and the pressure relief electromagnetic valve 29 are not opened, the gas will always remain in the gas box 16;

[0074] Therefore, during the multiple upward and downward movements of the upper movable rod 34, the gas pressure inside the gas box 16 gradually increases, and the pressure value inside the gas box 16 can be observed by using the pressure gauge 27. Similarly, a threshold value is set for the gas pressure of the pressure gauge 27. The threshold value is preferably a pressure range that the gas box 16 can normally withstand to prevent the gas box 16 from being damaged. When the pressure gauge 27 shows that the current gas pressure of the gas box 16 exceeds the threshold value, the pressure relief solenoid valve 29 will automatically open to release the pressure of the gas box 16.

[0075] In addition, when the discharge mechanism is started, the electromagnetic three-way valve 28 connects the jet pipe 43 with the air box 16. At this time, the high-pressure gas inside the air box 16 will enter the interior of the connecting air hood 37 through the jet pipe 43. Then the high-pressure gas will push the lower piston 44 downward along the cylindrical groove 45, thereby driving the ejector rod 46 and the pressure plate 39 to move downward as a whole to eject the "columnar" plant residue inside the filter cartridge 40. During this process, the electric lifting rod 10 will first drive the support tray 11 to descend to avoid affecting the discharge process of the plant residue. After seeing the plant residue being ejected, the staff can connect the jet pipe 43 with the exhaust pipe 4 through the electromagnetic three-way valve 28 , so that the air injection pipe 43 and the air box 16 are closed, and then under the action of the spring 47, the lower piston 44 can be reset to discharge the excess gas inside the air injection pipe 43, the connecting air cover 37 and the cylindrical groove 45, so that the pressure column 38 can be used again later; (During the discharge process, the state of the pressure column 38 at this time is: the bottom end of the pressure column 38 is located inside the filter cartridge 40, and the top end of the pressure column 38 is located inside the limit tube 24. The advantage of this is that during the discharge process, the unpressed plant material will not enter the filter cartridge 40 and be discharged, and it also prevents the unpressed plant material from being located at the top of the pressure column 38 and then being taken out of the lower guide cover 14);

[0076] The discharged "column-shaped" plant residue will be located on the top of the support tray 11. At this time, the staff only needs to push the "column-shaped" plant residue backward into the waste bin 18.

[0077] Specifically, a fixed box 9 is fixed to the outside of the electric lifting rod 10 inside the lower shell 6, and a waste box 18 for holding plant residues is arranged on the back of the fixed box 9 inside the lower shell 6. A dustproof mesh cover 26 is threadedly connected to the top of the air cylinder 17. The fixed box 9 can be used to further protect the electric lifting rod 10. At the same time, the height of the fixed box 9 is the same as that of the waste box 18. Therefore, it is convenient to quickly push accidentally fallen plant residues into the waste box 18. The dustproof mesh cover 26 can improve the cleanliness of the air entering the interior of the air cylinder 17 from the air intake check valve 51.

[0078] The overall principle of the above technical solution is as follows:

[0079] When in use, the plant material to be extracted is put into the feed box 3, and then the plant material enters between the knife holder 22 and the top block 21. Then, the motor 15 drives the driving wheel 31 to rotate through the controller 5, and then drives the driven wheel 30 to rotate. The top block 21 can be made to move back and forth in coordination with the connecting rod 32 and the connecting arm 33. When the top block 21 moves toward the knife holder 22, the plant material can be pushed toward the knife holder 22 and squeezed, so that the plant material is forcibly cut into "small pieces" by the blade on the knife holder 22;

[0080] The cut plant material will enter the upper guide cover 19 and the lower guide cover 14 in sequence and fall into the filter cartridge 40. At the same time, the turntable 36 will rotate along with the output shaft of the motor 15. Since the turntable 36 is in an inclined state, the U-shaped connecting frame 41 will be driven to move up and down during the rotation of the turntable 36, thereby driving the upper movable rod 34 and the lower movable rod 35 to move up and down as a whole.

[0081] When the upper movable rod 34 moves upward, it will simultaneously drive the upper piston 53 to move toward the top of the inner part of the air cylinder 17. Since the gas cannot be discharged through the inlet check valve 51, the air will enter the inner part of the air box 16 through the outlet check valve 52 and the air guide pipe 50 and be compressed.

[0082] When the lower movable rod 35 moves downward, it drives the pressing column 38 to move toward the inside of the filter cartridge 40, thereby squeezing the segmented plant material inside the filter cartridge 40 to achieve the "juice extraction" operation;

[0083] The squeezed plant juice will pass through the filter cartridge 40 into the interior of the connecting cylinder 13, and then enter the filter 7 through the pipeline. After being filtered by the filter 7, a purer plant juice is obtained and finally stored in the liquid collecting cylinder 8, while the plant residues and impurities will be located in the filter cartridge 40 and the filter 7. The filter 7 can be replaced regularly.

[0084] During the "juicing process", the circular bottom plate 48 will be blocked at the bottom of the filter cartridge 40. When the plant is "juicing" inside the filter cartridge 40, the pressure on the plant will be transmitted to the circular bottom plate 48. At this time, the pressure on the plant can be observed in real time through the pressure sensor 49. When the pressure reaches a certain value, the working process of the motor 15 is stopped, and then the discharge mechanism is started to discharge the columnar plant residues inside the filter cartridge 40.

[0085] The working principle of the discharge mechanism is as follows:

[0086] The electromagnetic three-way valve 28 connects the jet pipe 43 with the air box 16. At this time, the high-pressure gas inside the air box 16 enters the interior of the connecting air cover 37 through the jet pipe 43. Then, the high-pressure gas pushes the lower piston 44 downward along the cylindrical groove 45, thereby driving the ejector rod 46 and the pressure plate 39 to move downward as a whole, so as to eject the "columnar" plant residues inside the filter cartridge 40.

[0087] After the staff sees that the plant residues have been pushed out, they can connect the jet pipe 43 with the exhaust pipe 4 through the electromagnetic three-way valve 28, close the gap between the jet pipe 43 and the air box 16, and then under the action of the spring 47, the lower piston 44 and the pressure plate 39 can be reset to discharge the excess gas inside the jet pipe 43, the connecting air hood 37 and the cylindrical groove 45, so that the pressure column 38 can perform the plant "juice extraction" operation again later.

[0088] In the present invention, all the live components can be controlled by the controller 5. Since they are all conventional electronic components and belong to common knowledge in the art, they will not be described in detail again.

[0089] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
