[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-7As shown, a pressure filtration and separation device for processing freeze-dried product slurry includes a processing main cylinder 1, which provides a closed working environment to ensure that the slurry does not leak during processing. Fixed support legs 2 are evenly arranged around the lower end of the processing main cylinder 1. A feeding funnel 3 is designed at the upper end of the processing main cylinder 1. A grinding disc 4 is installed on the upper side of the interior of the processing main cylinder 1. An adjusting power structure 5 is provided on the lower side of the grinding disc 4 to drive the grinding disc 4 to rotate and move, thereby realizing the grinding operation of the slurry. A collection funnel 6 is clamped on the lower side of the interior of the processing main cylinder 1 to collect the ground slurry and guide it to the next stage of processing. An extrusion plate 7, a movable component, is installed on the lower surface of the collection funnel 6 to adjust the pressure of the collection funnel. Pressure is applied to the slurry in section 6 to help discharge the liquid portion, achieving solid-liquid separation. A support filter screen 8 is fixedly welded to the inner side of the lower end of the processing main cylinder 1. The function of the filter screen is to support the slurry while allowing the liquid portion to pass through, thereby achieving further solid-liquid separation. A lifting structure 9 is set at the center of the support filter screen 8. The operator first puts the slurry into the processing main cylinder 1 through the feeding funnel 3, starts the adjusting power structure 5, and drives the grinding disc 4 to grind the slurry. The ground slurry falls into the collecting funnel 6. Then, the position of the extrusion plate 7 is adjusted by the lifting structure 9 to apply pressure to the slurry for solid-liquid separation. The liquid portion is discharged through the support filter screen 8, while the solid portion remains above the filter screen and can be further processed as needed.

[0024] A discharge funnel is fixedly welded to the lower end of the main processing cylinder 1. An output control valve 101 is installed at the output end of the discharge funnel. Cleaning operation ports are opened on both sides of the main processing cylinder 1. A sealing operation plate 102 is hinged to one end of each cleaning operation port. After the slurry is filtered and separated, the operator can discharge the processed material from the discharge funnel by adjusting the output control valve 101. When the main processing cylinder 1 needs to be cleaned and maintained, the operator can open the sealing operation plate 102 and enter the main processing cylinder 1 through the cleaning operation port to perform the operation. After cleaning, the operator needs to close the sealing operation plate 102 and ensure that it is tightly sealed to prevent external impurities from entering the main processing cylinder 1.

[0025] The grinding disc 4 includes a positioning upper pressure plate 401 and a supporting lower grinding disc 402. The positioning upper pressure plate 401 is fixedly installed inside the upper end of the processing main cylinder 1 to ensure that the slurry is stably subjected to pressure during the grinding process, thereby achieving a uniform grinding effect. The supporting lower grinding disc 402 is located inside the positioning upper pressure plate 401 and is the actual grinding component. The adjusting power structure 5 includes a support fixing frame 501, a lifting electric screw 502, a limit slide rod 503, a support connecting plate 504, a rotary motor 505, and a rotating gear ring 506. The adjusting power structure 5 realizes the lifting and rotation adjustment of the grinding disc 4. The support fixing frame 501 is fixedly installed inside the processing main cylinder 1, and the lifting electric screw 502 is fixedly installed inside the processing main cylinder 1. The support is fixedly mounted on the support frame 501. Limiting slide rods 503 are arranged around the support frame 501. A support connecting plate 504 is fitted onto the upper side of the support frame 501. A rotary motor 505 is mounted on one side of the support connecting plate 504. A rotating gear ring 506 is embedded inside the lower grinding disc 402. A power mounting hole is provided at the center of the support frame 501. A lifting electric screw 502 is embedded inside the power mounting hole. The limiting slide rods 503 are fixedly welded to the support frame 501. Limiting sliding holes are provided around the support connecting plate 504, and the limiting sliding holes and the limiting slide rods 503 slide and engage with each other. A limiting sliding hole is provided at the center of the support connecting plate 504. The lifting threaded hole is threadedly connected to the lifting electric screw 502. When it is necessary to adjust the grinding pressure or grinding gap of the grinding disc 4, the operator can adjust the lifting of the lower grinding disc 402 by controlling the rotation direction and speed of the lifting electric screw 502. The precise control of the lifting electric screw 502 can ensure the uniformity and stability of the grinding gap. A rotating connecting groove is provided on the lower side of the lower grinding disc 402. The rotating connecting groove and the supporting connecting plate 504 are rotatably engaged. The rotating gear ring 506 is embedded in the rotating connecting groove. A rotating power groove is provided on one side of the supporting connecting plate 504. The rotating motor 505 is embedded in the rotating power groove. A drive gear is fixedly installed at the output end of the rotary motor 505. The drive gear meshes with the rotating gear ring 506. When it is necessary to change the grinding direction or grinding effect of the slurry, the operator can start the rotary motor 505. Through the meshing action of the drive gear and the rotating gear ring 506, the rotation adjustment of the supporting grinding disc 402 can be realized. The forward and reverse control of the rotary motor 505 can easily change the grinding direction. After the lifting and rotation adjustment is completed, the operator can put the slurry into the processing main cylinder 1 and guide it to the grinding disc 4 through the feeding funnel 3. With the rotation and lifting movement of the supporting grinding disc 402, the slurry will be subjected to uniform grinding and crushing action, thereby achieving the expected processing effect.

[0026] The lifting structure 9 includes a lifting motor 901, a lifting screw 902, a lifting limit frame 903, and a power slider 904, which work together to achieve the lifting and adjustment of the extrusion upper platen 7. The lifting motor 901 is fixedly installed on the lower surface of the supporting filter screen 8 and is the power source of the lifting structure 9. The lifting screw 902 is located at the output end of the lifting motor 901. The lifting limit frame 903 is designed on the upper surface of the supporting filter screen 8. The power slider 904 is snapped into the inside of the lifting limit frame. The lifting motor 901 and the supporting filter screen 8 are fixedly connected at their center positions. The lifting screw 902 and the output end of the lifting motor 901 are fixedly welded together. The upper end of the lifting screw 902 is rotatably engaged with the lifting limit frame 903. A lifting connection hole is opened at the center position of the extrusion upper platen 7. The lifting connection hole is fixedly welded to the lifting limit frame. The inside of the lifting limit frame is... A lifting threaded hole is provided, which is threadedly connected to a lifting screw 902. The threaded portion of the lifting screw 902 interacts with the lifting threaded hole to achieve lifting movement. The operator starts the lifting motor 901, causing it to rotate. The rotation of the lifting motor 901 drives the lifting screw 902 to rotate as well. Since the lifting screw 902 and the lifting threaded hole are threadedly connected, the rotation of the lifting screw 902 is converted into the up-and-down movement of the power slider 904. The up-and-down movement of the power slider 904 drives the connected extrusion platen 7 to adjust its height. In this way, the operator can adjust the height of the extrusion platen 7 by controlling the rotation direction and speed of the lifting motor 901, thereby achieving pressure control of the slurry. During the lifting and lowering process of the extrusion platen 7, the slurry is subjected to pressure from the extrusion platen 7, thus achieving solid-liquid separation. The liquid portion is discharged through the support filter screen 8, while the solid portion remains above the filter screen.
