[0020] In summary, the improvement of this embodiment lies in: The mixing, blending, and filtration functions are integrated into the same device. The raw material slurry and water are directly and uniformly dispersed and initially filtered in the mixing and filtering cylinder 2, avoiding material loss or unevenness caused by intermediate transfer, simplifying the process and improving production efficiency. The conical filter plate 42, together with multiple cleaning rollers 44 set on the ring plate 41, uses the meshing transmission of gear 444 and fixed conical tooth ring 445 to realize the revolution and high-speed rotation of the cleaning rollers 44 simultaneously during the mixing process. The bristles on the roller body 442 continuously scrape the surface of the conical filter plate 42, pushing the trapped residue towards the center, effectively preventing filter hole blockage and maintaining high-throughput stable filtration. Air is supplied to the air chamber inside the cleaning roller through the air pump 51. The gas is sprayed out through the aeration holes to form microbubbles and upward airflow, which on the one hand agitates the filter residue to prevent compaction, and on the other hand reduces filtration resistance and improves the filtrate permeability. In the cleaning stage, it can also help to flush away residues and improve cleaning efficiency.

[0021] Based on the above, other structures also need to be disclosed in detail, such as: A central opening is provided on the conical filter plate 42, and a collection cylinder 6 is installed in the central opening. The collection cylinder 6 rests against the circular block 43. A bottom filter plate 61 is fixedly connected to the bottom of the cylinder. The diameter of the filter holes of the bottom filter plate 61 is smaller than that of the conical filter plate 42. An installation plate 71 is fixedly connected to the inner wall of the liquid storage cylinder 1. Two waterproof electric telescopic rods 72 are symmetrically fixedly connected to the installation plate 71. A rectangular block 73 is fixedly connected to the telescopic end of the waterproof electric telescopic rods 72. Two fixing plates are symmetrically fixedly connected to the collection cylinder 6. 62. The fixed plate 62 has a rectangular opening, and the rectangular block 73 passes through the rectangular opening. An L-shaped plate 63 is fixedly connected to the fixed plate 62, and the rectangular block 73 abuts against the L-shaped plate 63. The fixed plate 62 has an installation opening, and the rectangular block 73 has an installation groove. Installation bolts 74 are fixedly installed in the installation opening and the installation groove. The waterproof electric telescopic rod 72 is controlled to retract, which drives the collecting cylinder 6 to move downward. The collecting cylinder 6 moves to abut against the lower end face of the conical filter plate 42, and the liquid filtered from the conical filter plate 42 enters the collecting cylinder 6.

[0022] A liquid outlet 11 is provided on the lower end face of the liquid storage cylinder 1, and a connecting cover 111 is provided on the liquid outlet 11. A through-hole is provided on the liquid storage cylinder 1, and an arc-shaped sealing plate 12 is provided at the through-hole. The arc-shaped sealing plate 12 is fixedly connected to the liquid storage cylinder 1 by fixing bolts. The filtered and clarified plant beverage flows into the lower part of the liquid storage cylinder 1 for storage and can be discharged from the liquid outlet 11 at the bottom for subsequent filling. By opening the arc-shaped sealing plate 12, the collection cylinder 6 can be easily removed, the filter residue can be poured out and cleaned.

[0023] In summary, the working principle of this solution is as follows: Open the cylinder cover 211 and initially mix the plant raw material powder with an appropriate amount of dispersant in the feed cylinder 21 to form a readily flowable slurry. Close the cylinder cover 211 and inject a measured amount of water into the stirred filter cylinder 2 through the water inlet pipe 8. Start the motor 31 to drive the stirring assembly. At the same time, open the switch valve at the lower end of the feed cylinder 21 to allow the plant slurry to flow into the stirred filter cylinder 2. Under the planetary composite stirring of multiple stirring plates 36, the slurry and water are quickly and evenly dispersed and mixed to form the plant slurry to be filtered. The mixed slurry flows towards the conical filter plate 42 under the action of gravity. Larger particles and fibers in the slurry are trapped on the surface of the conical filter plate 42, while the filtrate flows downward through the filter holes. During this process, the vertical rod 34 of the stirring assembly drives the cleaning roller 44 to revolve. At the same time, through the meshing of the gear 445 and the fixed conical tooth ring 444, the cleaning roller 44 is driven to rotate at high speed. The bristles on it continuously scrape the surface of the conical filter plate 42, pushing the trapped filter residue to the center of the bottom of the cone to prevent the filter holes from clogging and ensure continuous and smooth filtration. The filtered clarified plant beverage flows into the lower part of the storage tank 1 for storage and can be discharged from the bottom outlet 11 for subsequent filling. After filling, water is added through the water inlet pipe 8, and the waterproof electric telescopic rod 72 is controlled to retract, which drives the collecting cylinder 6 to move downward. When the collecting cylinder 6 moves to the lower end face of the conical filter plate 42, the motor 31 and the air pump 51 are started. The cleaning roller 44 continues to revolve and rotate. The gas sprayed by the air pump 51 is transported through the pipeline to the air chamber of each cleaning roller 442 and sprayed out from the aeration hole. The sprayed bubbles generate agitation, further preventing the filter residue from accumulating and compacting on the surface of the filter plate, and forming an upward micro-airflow to reduce the filtration resistance. The liquid filtered from the conical filter plate 42 enters the collecting cylinder 6. After filtration is complete, stop motor 31 and air pump 51, open the arc-shaped sealing plate 12 on the side, and the collection cylinder 6 can be easily removed, the filter residue poured out and cleaned, and then reinstalled.

[0024] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
