This technology utilizes some special plants with strong tolerance and enrichment ability to heavy metals. The plants used are required to have the characteristics of large biomass, fast growth, strong resistance to diseases and pests, and strong enrichment ability to a variety of heavy metals;

[0003] After the extraction of plants or traditional Chinese medicine components, etc., it is generally necessary to filter the extraction residue, and a filtration device is required. The existing filtration device uses a filter plate to intercept the residue to achieve the filtration of solid residue. However, since traditional Chinese medicine or crushed plant bodies are often relatively fluffy, a lot of essence liquid will be entrained in the filtered solid residue. If the solid residue is directly discarded, a large amount of essence liquid will be wasted, and the filter plate is prone to blockage, affecting the filtration effect. Summary of the Utility Model

The cleaning component includes a mounting cylinder connected to the top surface of the mounting plate. The middle part of the inner top surface of the mounting cylinder is slidably and rotatably connected with a rotating rod. The lower part of the side surface of the rotating rod is threadedly connected with a pressing block, and the pressing block is elastically connected to the inner top surface of the mounting cylinder.

Detailed implementation mode

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] The present utility model will be further described below with reference to the embodiments.

[0021] Referring to Figures 1 to 4 , Embodiment: A plant extraction filtration device includes an upper housing 1 and a lower housing 2, and further includes a pressing plate 3 which is movably connected inside the upper housing 1 through an electric telescopic rod connected to the top surface of the upper housing 1. The upper part of the annular inner surface of the upper housing 1 is penetrated and connected with a liquid inlet pipe 4, and the liquid inlet pipe 4 includes a pipeline and a one-way valve. The upper part of the annular inner surface of the lower housing 2 is provided with a filter plate 5, and a mounting plate 6 is fixedly installed at the lower part of the annular inner surface of the lower housing 2 close to the filter plate 5;

[0022] A cleaning assembly is arranged on the top surface of the mounting plate 6 and is used for cleaning the filter plate 5. The cleaning assembly includes a mounting cylinder 7 connected to the top surface of the mounting plate 6. The middle part of the inner top surface of the mounting cylinder 7 is slidably and rotatably connected with a rotating rod 8. The lower part of the side surface of the rotating rod 8 is threadedly connected with an extrusion block 9, and the extrusion block 9 is elastically connected with the inner top surface of the mounting cylinder 7. The inner bottom surface of the mounting cylinder 7 is penetrated and provided with uniformly distributed connecting holes 10. The top of the rotating rod 8 extends to the outside of the mounting cylinder 7 and is connected with a limiting block 11. The bottom of the side surface of the limiting block 11 is connected with the filter plate 5, and a brush block 12 is arranged at the top of the limiting block 11. A card slot 13 is opened in the middle of the inner bottom surface of the mounting cylinder 7, and a clamping block 14 is fixedly connected to the bottom surface of the rotating rod 8 corresponding to the position of the card slot 13;

[0023] When using this filtering device for filtration, first, the extraction liquid with solid residues enters the interior of the upper housing 1 through the liquid inlet pipe 4. After the addition of the extraction liquid is completed, the electric telescopic rod arranged on the top surface of the upper housing 1 is turned on. At this time, the electric telescopic rod drives the pressing plate 3 to squeeze the extraction liquid inside the upper housing 1 to move in the direction close to the filter plate 5. By squeezing the extraction liquid, the filtration effect of the extraction liquid passing through the filter plate 5 for filtration work is improved. When the pressing plate 3 moves to a position close to the filter plate 5, most of the extraction liquid has been squeezed and filtered. At this time, as the pressing plate 3 continues to move, the pressing plate 3 will further squeeze and filter the residues filtered on the filter plate 5, thereby further removing the residual essence liquid in the solid residues;

[0024] Further, when the pressing plate 3 squeezes the extraction liquid and moves it close to the filter plate 5, since the extraction liquid cannot quickly pass through the filter plate 5 for filtration, the squeezing force of the pressing plate 3 acting on the extraction liquid acts on the filter plate 5. When squeezing, the filter plate 5 squeezes the limit block 11. The squeezing force causes the limit block 11 to drive the rotating rod 8, the extrusion block 9, and the clamping block 14 to move in the direction close to the clamping groove 13 against the elastic force between the extrusion block 9 and the mounting cylinder 7 until the clamping block 14 enters the interior of the clamping groove 13 to complete the clamping work;

[0025] The cleaning component further includes a first connecting pipe 15 uniformly penetrating and connected to the top surface of the mounting plate 6. The lower end of the first connecting pipe 15 is connected to a movable block 16. The movable block 16 is elastically connected to the inner bottom surface of the lower housing 2. The annular inner surface of the lower housing 2 is penetrated and connected with a second connecting pipe 18 at a position close to the mounting plate 6. The annular outer surface of the lower housing 2 is connected with an elastic airbag 17 at a position close to the mounting plate 6. One end of the second connecting pipe 18 away from the lower housing 2 is penetrated and connected to the elastic airbag 17;

[0026] It should be noted that after the extraction liquid is filtered through the filter plate 5, it enters the cavity between the filter plate 5 and the mounting plate 6, and then enters the lower part of the movable block 16 through the first connecting pipe 15. As the amount of extraction liquid entering the lower part of the movable block 16 gradually increases, the extraction liquid squeezes the movable block 16. The squeezing force causes the movable block 16 to move upward inside the lower housing 2 against the elastic force between it and the lower housing 2. During the movement of the movable block 16, the gas in the lower housing 2 located above the movable block 16 is squeezed. Since the bottom of the rotating rod 8 is clamped and restricted by the clamping groove 13 through the clamping block 14, at this time, the gas inside the lower housing 2 cannot squeeze the extrusion block 9 to cause the rotating rod 8 to rotate; Therefore, the squeezing force causes the gas inside the movable block 16 to enter the interior of the elastic airbag 17 through the second connecting pipe 18, causing the elastic airbag 17 to undergo elastic deformation, achieving the effect of storing gas;

[0027] Further, when it is necessary to clean the filter plate 5 after the filtration of the extraction liquid is completed, the upper housing 1 is separated from the lower housing 2. At this time, the extrusion force of the pressing plate 3 on the filter plate 5 disappears. Under the elastic force of the elastic deformation recovery between the extrusion block 9 and the mounting cylinder 7, the extrusion block 9 drives the rotating rod 8 and the clamping block 14 to move away from the clamping groove 13 until the clamping between the clamping block 14 and the clamping groove 13 is cancelled. At this time, the restriction of the clamping groove 13 on the clamping block 14 is cancelled. Under the elastic force of the elastic deformation recovery of the elastic airbag 17, the gas inside the elastic airbag 17 enters the cavity inside the lower housing 2 above the movable block 16 through the second connecting pipe 18, and then enters the inside of the mounting cylinder 7 through the connecting hole 10 to extrude the extrusion block 9. The extrusion force causes the extrusion block 9 to move upward on the surface of the rotating rod 8 against the elastic force between it and the mounting cylinder 7. Since the rotating rod 8 is threadedly connected to the extrusion block 9 and the thread groove gap at the connection is relatively large, the rotating rod 8 will rotate when the extrusion block 9 moves. When the rotating rod 8 rotates, it drives the brush block 12 to rotate through the limiting block 11. When the brush block 12 rotates, it cleans the filter residue on the filter plate 5, and the brush at the lower part of the brush block 12 cleans the filter holes of the filter plate 5, thereby ensuring the filtering effect of the filter plate 5 for the next use.

[0028] Refer to Figure 3 , a uniformly distributed third connecting pipe 20 is connected through the annular inner surface of the mounting cylinder 7 near the connecting hole 10, and the end of the third connecting pipe 20 away from the mounting cylinder 7 extends to the top surface of the mounting plate 6; when the filter plate 5 drives the rotating rod 8 and the clamping block 14 to move closer to the clamping groove 13, the side surface of the extrusion block 9 gradually blocks the opening of the third connecting pipe 20 to avoid the problem of gas entering the inside of the third connecting pipe 20. When cleaning the surface of the filter plate 5, the extrusion block 9 no longer blocks the third connecting pipe 20, and the gas entering the inside of the mounting cylinder 7 enters the inside of the third connecting pipe 20, and then enters between the filter plate 5 and the mounting plate 6 through the third connecting pipe 20. Since the inner diameter of the third connecting pipe 20 is much larger than the inner diameter of the filter holes on the filter plate 5, that is, the amount of gas entering between the filter plate 5 and the mounting plate 6 is greater than the amount of gas discharged through the unblocked filter holes on the filter plate 5, and since the extraction liquid at the lower part of the movable block 16 has not been taken out at this time, the gas cannot enter the cavity at the lower part of the movable block 16 through the first connecting pipe 15. Therefore, as the amount of gas entering between the filter plate 5 and the mounting plate 6 gradually increases, the gas extrusion force causes the gas to enter the filter holes on the filter plate 5. If the filter holes are blocked by filter residue, the gas extrudes the filter residue, and the extrusion force extrudes the filter residue, causing the filter residue to be discharged from the filter holes on the filter plate 5, improving the cleaning effect of the filter plate 5.

[0029] It should be noted that after the filtrate plate 5 is cleaned, the filtered extract inside the lower housing 2 can be taken out through the drain pipe at the lower part of the side of the lower housing 2. After the extract is taken out, the extrusion force of the extract on the movable block 16 disappears. Under the action of the elastic force that restores the elastic deformation between the movable block 16 and the lower housing 2, the movable block 16 moves downward inside the lower housing 2. During the movement, under the action of the external air pressure, the external gas enters between the movable block 16 and the mounting plate 6 through the filter holes on the filtrate plate 5, the third connecting pipe 20, and the connecting hole 10 to perform the gas replenishment work to ensure the normal progress of the next operation.

[0030] Referring to Figure 3 , an elastic layer 21 is connected to the top surface of the limit block 11. The limit block 11 is elastically connected to the brush block 12 through the elastic layer 21. A placement groove 22 is provided on the top surface of the filtrate plate 5 corresponding to the position of the brush block 12; when the pressing plate 3 moves to a position close to the filtrate plate 5 to squeeze the filter residue on the filtrate plate 5, when the pressing plate 3 moves to the brush block 12, it squeezes the brush block 12, and the extrusion force causes the brush block 12 to overcome the elastic force of the elastic layer 21 and enter the inside of the placement groove 22, thereby avoiding the problem that the brush block 12 blocks the pressing plate 3 and affects the extrusion effect of the pressing plate 3 on the filter residue.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present invention.
