However, the efficiency of manual processing is low, resulting in too long downtime of the filtration system and reduced extraction efficiency.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0029] like Figure 1-4 As shown, the present application provides a multi-stage filtration device for directional extraction of plants, including a centrifugal separator 1 and a filtering mechanism, a water inlet pipe 3 is installed on the top of the centrifugal separator 1, a conveying mechanism 2 is arranged between the centrifugal separator 1 and the filtering mechanism, the filtering mechanism includes a support seat 4, a top cover 5 and a turntable 6, a connecting column 12 is fixedly connected between the support seat 4 and the top cover 5, the turntable 6 is rotatably connected to the connecting column 12, two filtering channels are provided inside the turntable 6, and filter elements 9 are arranged in the two filtering channels, the filter element 9 includes a filter screen 91, the filter screen 91 is adapted to the filtering channel, and a driving assembly 7 is installed on the top cover 5.

[0030] A connecting groove 13 and a sewage trough 14 are respectively provided on the top of the support seat 4, and a drain pipe 10 and a sewage pipe 11 are respectively installed on the bottom of the support seat 4, the drain pipe 10 is connected with the connecting groove 13, and the sewage pipe 11 is connected with the sewage trough 14, the filter screen 91 is rotatably connected to the inner wall of the filter channel, and the outer wall of the filter screen 91 is fixedly connected to a connecting shaft 92, and the connecting shaft 92 is rotatably connected to the turntable 6, the top of the support seat 4 is fixedly connected to a face gear ring 15, and the end of the connecting shaft 92 away from the filter screen 91 is fixedly connected to a transmission gear 93 meshing with the face gear ring 15, the face gear ring 15 is partially provided with teeth, and the cross-section of the sewage trough 14 is fan-shaped.

[0031] This solution is a kind of equipment used to extract specific components from plant materials. It uses multiple filtering stages to gradually remove unwanted solid impurities and separate valuable extracts.

[0032] Specifically, the plant raw material is introduced into the centrifugal separator 1 through the water inlet pipe 3 for preliminary separation. With the action of the conveying mechanism 2, the plant raw material is conveyed to the filtering mechanism. The filter screen 91 in the filtering mechanism can intercept the plant residues to achieve the purpose of multi-stage filtration. The filtered raw material falls into the connecting groove 13 and is finally discharged through the drain pipe 10 for subsequent treatment. In addition, by periodically closing the conveying mechanism 2 and starting the driving component 7, the conveying mechanism 2 stops conveying the raw material, and the driving component 7 is used to control the turntable 6 to intermittently rotate 180°, so that the two filter screens 91 are swapped in position, and then the conveying mechanism 2 resumes work, and the switched filter screen 91 can continue to carry out plant separation. The interception of plant residues reduces equipment downtime and improves filtration efficiency. However, during the rotation of the turntable 6, one of the transmission gears 93 can mesh with the teeth on the face gear ring 15, causing the transmission gear 93 to rotate, thereby driving the connecting shaft 92 and the filter screen 91 to rotate. When the turntable 6 completes a 180° rotation, the filter screen 91 flips 180°, so that the plant residues intercepted on the surface of the filter screen 91 automatically fall into the sewage tank 14 under the action of gravity. The above operation can be repeated regularly, avoiding the tediousness and inconvenience of manual cleaning, achieving the purpose of self-cleaning of the filter screen 91, ensuring the cleanliness of the filter screen 91 to be switched, reducing labor costs, and improving the convenience of operation.

[0033] During the filtering process, the delivery pump 21, the connecting groove 13 and one of the filtering channels are coaxially arranged to form a plant residue intercepting channel.

[0034] In addition, when the turntable 6 rotates 180° once, the filter screen 91 with sand and gravel intercepted on the surface rotates a certain angle until the filter channel can no longer form a plant residue interception channel with the delivery pump 21 and the connecting groove 13. Only then will the active gear 72 engage with the teeth on the face gear ring 15 to perform a flipping action. This avoids the problem of impurities falling due to premature flipping of the filter screen 91, and ensures that all the intercepted impurities can fall into the sewage tank 14.

[0035] It should be noted that the filter screen 91 is adapted to the filter channel so that the filter screen 91 can rotate in the filter channel about the axis of the connecting shaft 92, and the centrifuge 1 can quickly separate the solid impurities in the plant material by high-speed rotation. This technology is existing technology, so it will not be elaborated in detail.

[0036] like Figure 3 As shown, a through hole is opened inside the turntable 6, and a connecting post 12 passes through the through hole. The connecting post 12 is rotatably connected to the inner wall of the through hole.

[0037] In this embodiment, the turntable 6 can rotate on the outer side wall of the connecting column 12 through the cooperation between the connecting column 12 and the through hole.

[0038] like Figure 2-3 As shown, the driving assembly 7 includes a motor 71 , the output end of the motor 71 passes through the top cover 5 and is fixedly connected to a driving gear 72 , and the outer side wall of the top cover 5 is fixedly connected to an outer gear ring meshing with the driving gear 72 .

[0039] In this embodiment, the motor 71 is used to control the driving gear 72 to rotate, and the driving gear 72 is meshed with the outer gear ring to control the turntable 6 to intermittently rotate 180°.

[0040] like Figure 3-4 As shown, the conveying mechanism 2 includes a conveying pump 21, and the input end and output end of the conveying pump 21 are respectively installed with a connecting pipe 1 22 and a connecting pipe 2 23, the connecting pipe 1 22 is connected to the bottom of the centrifugal separator 1, and one end of the connecting pipe 23 passes through the top cover 5, and a cleaning assembly 8 is arranged on the top cover 5, and the cleaning assembly 8 includes a cleaning pipe 81 and a high-pressure nozzle 82, the high-pressure nozzle 82 is fixed to the bottom end of the top cover 5, the cleaning pipe 81 is fixed to the top of the top cover 5 and is connected to the high-pressure nozzle 82, the cleaning pipe 81 corresponds to the position of the sewage pipe 11, and the end position of the connecting pipe 23 corresponds to the position of the drain pipe 10.

[0041] In this embodiment, the plant material discharged into the centrifugal separator 1 can be transported to the plant residue interception channel through the provided delivery pump 21. In addition, the cleaning pipe 81 is connected to the external water source. When the turntable 6 completes a single 180° rotation, the filter screen 91 of the intercepted plant residue is directly below the high-pressure nozzle 82. The filter screen 91 can be flushed by the high-pressure nozzle 82 by connecting to the water source. The cleaned sewage falls into the sewage tank 14 and is finally discharged through the sewage pipe 11.

[0042] It should be noted that a reserved groove is provided at the bottom end of the top cover 5 , and the high-pressure nozzle 82 is installed on the inner wall of the reserved groove to avoid affecting the rotation of the turntable 6 .

[0043] Working principle:

[0044] The plant raw material is introduced into the centrifugal separator 1 through the water inlet pipe 3 for preliminary separation. With the action of the conveying mechanism 2, the plant raw material is conveyed to the filtering mechanism. The filter screen 91 in the filtering mechanism can intercept the plant residues to achieve the purpose of multi-stage filtration. The filtered raw material falls into the connecting groove 13 and is finally discharged through the drain pipe 10 for subsequent treatment. In addition, by periodically closing the conveying mechanism 2 and starting the driving component 7, the conveying mechanism 2 stops conveying the raw material, and the driving component 7 is used to control the turntable 6 to intermittently rotate 180°, so that the two filter screens 91 are swapped in position, and then the conveying mechanism 2 resumes work, and the switched filter screen 91 can continue to intercept the plant residues. The operation can reduce equipment downtime and improve filtering efficiency. However, during the rotation of the turntable 6, one of the transmission gears 93 can mesh with the teeth on the face gear ring 15, so that the transmission gear 93 rotates on its own, thereby driving the connecting shaft 92 and the filter screen 91 to rotate. When the turntable 6 completes a 180° rotation, the filter screen 91 flips 180°, so that the plant residues intercepted on the surface of the filter screen 91 automatically fall into the sewage tank 14 under the action of gravity. At this time, the filter screen 91 can be flushed by connecting to a water source and using a high-pressure nozzle 82. The cleaned sewage falls into the sewage tank 14 and is finally discharged through the sewage pipe 11. By regularly repeating the above operation, the purpose of self-cleaning of the filter screen 91 is achieved.

[0045] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
