[0002] Biopharmaceuticals are a high-end industry that integrates research findings from multiple disciplines, including microbiology, biology, medicine, and biochemistry. Through the in-depth development of natural biological materials such as organisms and tissues, it manufactures products for disease prevention, treatment, and diagnosis. Solid-liquid separation is an indispensable and crucial step in the biopharmaceutical process, its effectiveness directly impacting subsequent drug purification and formulation quality, and is vital for ensuring drug quality and production efficiency. However, currently widely used solid-liquid separation equipment still suffers from significant technical bottlenecks. Taking the equipment with announcement number "CN219128530U" as an example, although it uses a motor-driven filter scraper to agitate and separate the solid-liquid mixture, accelerating the discharge of liquid through the filter plate, it has obvious shortcomings in handling solid residue. After completing solid-liquid separation, the equipment must be stopped, and operators must manually restart it to clean the residue. This not only interrupts production and significantly reduces overall production efficiency but also increases labor costs. More importantly, frequent manual intervention greatly increases the risk of drug contamination, making it difficult to meet the stringent requirements of the biopharmaceutical industry for continuous, sterile, and efficient production. Therefore, existing technologies have certain defects and shortcomings, necessitating design improvements. Utility Model Content

[0014] 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.
[0015] Example Please refer to Figure 1-5 A solid-liquid separation device according to this embodiment includes a tank 1. Fixing blocks 2 are fixedly installed on the upper ends of both sides of the tank 1. A driving mechanism 3 is fixedly installed on the top of the fixing blocks 2. A centrifugal screen 4 is fixedly installed at the output end of the driving mechanism 3. The centrifugal screen 4 is rotatably connected to the inside of the tank 1. An agitation component 5 is fixedly installed on the outside of the fixing blocks 2. The bottom of the agitation component 5 extends into the lower end of the centrifugal screen 4. A waste discharge pipe 6 is fixedly connected to the bottom of the centrifugal screen 4. A discharge solenoid valve 7 is fixedly installed in the middle of the bottom of the tank 1. A drain solenoid valve 8 is fixedly installed on one side of the bottom of the tank 1. The input ends of the discharge solenoid valve 7 and the drain solenoid valve 8 are both connected to the inside of the tank 1. The bottom of the waste discharge pipe 6 is inserted into the input end of the discharge solenoid valve 7. The drive mechanism 3 includes an inner support 31, which is fixedly installed on the top of the fixed block 2. An annular rail 32 is fixedly installed in the middle of the top of the inner support 31. A slip ring 33 is rotatably connected inside the annular rail 32. Connecting arms 34 are fixedly connected to both sides of the bottom of the slip ring 33. The bottom of the connecting arms 34 is fixedly connected to both sides of the top of the tank 1. A drive assembly 35 is fixedly installed on one side of the top of the inner support 31. During the application of this device, when the solid-liquid separation equipment is working, after the material to be separated enters the centrifugal screen 4 inside the tank 1, the drive assembly 35 in the drive mechanism 3 is activated, driving the slip ring 33 to rotate inside the annular rail 32. The slip ring 33 drives the centrifugal screen 4 inside the tank 1 through the connecting arms 34. High-speed rotation utilizes centrifugal force to achieve solid-liquid separation. The liquid flows into the bottom of the tank 1 through the mesh of the centrifugal screen 4 and is discharged through the drain solenoid valve 8. The separated solids remain in the centrifugal screen 4. When it is necessary to discharge the solids, the stirring component 5 is activated, with its bottom extending into the lower end of the centrifugal screen 4. In conjunction with the rotation of the centrifugal screen 4, the solid waste is pushed along the conical surface of the centrifugal screen 4 to the waste discharge pipe 6 at the bottom and discharged from the tank 1 through the discharge solenoid valve 7. Throughout the process, the fixed block 2 supports the drive mechanism 3, and the rotational connection between the annular rail 32 and the slip ring 33 ensures the stable rotation of the centrifugal screen 4. The drain solenoid valve 8 and the discharge solenoid valve 7 control the timing of the discharge of the liquid and solid phases, respectively, realizing an automated process for solid-liquid separation and discharge.
[0016] Please refer to Figures 1-3 and Figure 5A fixing ring 9 is fixedly installed on the upper part of the outer surface of the tank body 1. Support legs 10 are fixedly installed at equal intervals in a ring shape at the bottom of the fixing ring 9. The bottom of the tank body 1 is set as a cone shape. The lower end of the centrifugal mesh cylinder 4 is also set as a cone shape. A support base ring 11 is fixedly installed at the bottom of the support leg 10. An anti-slip pad ring is fixedly connected to the bottom of the support base ring 11. The drive assembly 35 includes a gear ring 351 and a first motor 352. The first motor 352 is fixedly installed on the top side inside the support frame. A gear 353 is fixedly installed through the support frame at the output end of the first motor 352. The gear ring 351 is fixedly installed on the top of the slip ring 33. The gear 353 and the gear ring 351 are meshed and connected. A splash shield 12 is fixedly installed at the upper end inside the centrifugal mesh cylinder 4. The splash shield 12 is set in a conical funnel shape. During the application of this equipment, when the equipment is running, the fixing ring 9 and the support leg 10 will stably support the tank body 1 on the ground. The support base ring 11 and the anti-slip pad ring at the bottom are reinforced. To ensure stability and prevent shaking during operation, the conical design at the bottom of the tank 1 and centrifugal screen 4 facilitates the collection and discharge of solid waste after solid-liquid separation. The first motor 352 is started, and its output gear 353 meshes with the toothed ring 351 at the top of the slip ring 33, driving the slip ring 33 to rotate within the annular rail 32. This, in turn, drives the centrifugal screen 4 to rotate at high speed within the tank 1 via the connecting arm 34, achieving solid-liquid separation using centrifugal force. The separated liquid flows through the mesh of the centrifugal screen 4 into the bottom of the tank 1 and is discharged via the drain solenoid valve 8. The conical funnel-shaped anti-splash shield 12 inside the centrifugal screen 4 prevents solid particles from splashing during centrifugation and guides the liquid to flow quickly to the bottom of the tank 1, improving separation efficiency. When solid waste needs to be discharged, the agitator 5 pushes the solid waste along the conical bottom of the centrifugal screen 4 and tank 1 to the waste discharge pipe 6, which then discharges it via the discharge solenoid valve 7, completing the solid-liquid separation and discharge process.
[0017] Please refer to Figures 1-4The agitation assembly 5 includes an outer support 51, which is fixedly installed on the outside of the fixed block 2. A top plate 52 is fixedly installed on the top of the outer support 51, and a second motor 53 is fixedly installed on the top of the top plate 52. The output end of the second motor 53 passes through the top plate 52 and is fixedly installed with a rotating shaft 54. The end of the rotating shaft 54 passes through the inner side of the annular rail 32 and the slip ring 33 and extends into the interior of the centrifugal mesh cylinder 4. A stirring auger 55 is fixedly connected to the lower end of the outer surface of the rotating shaft 54. The top of the stirring auger 55 is... Both the bottom and the top are conical, and the side of the stirring auger 55 is diamond-shaped. The overall cross-sectional shape of the slip ring 33 and the internal cavity cross-sectional shape of the annular rail 32 are both convex. During the application of this equipment, when the stirring component 5 is working, the outer support 51 is fixed to the outside of the fixed block 2. After the second motor 53 on the top plate 52 is started, the output end drives the rotating shaft 54 to rotate. The rotating shaft 54 passes through the inner side of the annular rail 32 and the slip ring 33 and extends into the centrifugal mesh cylinder 4. Since both the slip ring 33 and the annular rail 32 are conical, the overall cross-sectional shape of the slip ring 33 and the internal cavity cross-sectional shape of the annular rail 32 are convex. The centrifugal screen 4 has a convex cross-section, forming a stable sliding fit. When the rotating shaft 54 rotates, it will not cause the slip ring 33 to deviate, ensuring that the rotation of the centrifugal screen 4 and the transmission of the stirring component 5 do not interfere with each other. The stirring auger 55 at the lower end of the rotating shaft 54 has a double conical structure. The diamond-shaped design on the side increases the contact area and pushing force with the solid waste. When the centrifugal screen 4 rotates at high speed under the action of the drive mechanism 3 to perform solid-liquid separation, the second motor 53 is started. The stirring auger 55 rotates with the rotating shaft 54. Its conical top cooperates with the anti-splash shield 12 at the upper end of the centrifugal screen 4 to guide the solid waste to move downward. The bottom conical structure fits against the conical inner wall of the lower end of the centrifugal screen 4. Through the spiral pushing action of the diamond-shaped side, the waste is concentrated along the conical wall of the centrifugal screen 4 to the bottom and finally discharged through the waste discharge pipe 6. In this process, the conical and diamond-shaped structure design of the stirring auger 55 can not only adapt to the spatial structure of the centrifugal screen 4, but also efficiently assist the discharge of solid waste through the axial thrust generated by the rotation, thereby improving the overall processing efficiency of the equipment.
[0018] Operating principle and advantages: During application, this device achieves efficient solid-liquid separation and solid discharge through the coordinated design of the drive mechanism 3 and the stirring component 5. In the solid-liquid separation stage, the drive mechanism 3 plays a core role: after the material to be separated is placed in the tank inside the centrifugal mesh cylinder 4, the first motor 352 is started. The output shaft of the motor drives the gear 353 to rotate. The gear 353 meshes with the gear ring 351, causing the gear ring 351 to generate circumferential motion. The slip ring 33 fixedly connected to the bottom of the gear ring 351 rotates synchronously and drives the centrifugal mesh cylinder 4 to rotate inside the tank 1 through the connecting arm 34. The high-speed rotation of the centrifugal mesh cylinder 4 generates a centrifugal force field, realizing the effective separation of the solid and liquid phases. In addition, the conical funnel-shaped anti-splash shield 12 installed inside the centrifugal mesh cylinder 4 prevents solid particles from splashing under the action of centrifugal force. On the other hand, its flow guiding structure guides the separated liquid phase to be discharged through the drain solenoid valve 8 at the bottom of the tank 1, optimizing the separation process and improving the solid-liquid separation efficiency. In the solid material discharge stage, the stirring component 5 and the drive mechanism 3 work together. After the discharge solenoid valve 7 is opened, the second motor 53 is started. Its output shaft drives the rotating shaft 54 and the stirring auger 55 fixed on the rotating shaft 54 to rotate. At the same time, the first motor 352 drives the centrifugal screen 4 to rotate in the opposite direction. Under the relative motion of the two, the stirring auger 55 pushes the solid waste in the centrifugal screen 4 downward. Combined with the conical structure of the centrifugal screen 4 itself, the solid waste enters the discharge solenoid valve 7 through the waste discharge pipe 6 and is discharged from the equipment. This design does not require disassembly of the equipment and realizes the automated discharge of solid waste. After the discharge is completed, the next round of material loading and separation operation can be carried out, reducing equipment downtime and improving production continuity. In addition, the conical shape of the stirring auger 55 is adapted to the conical contour of the bottom of the centrifugal screen 4, which reduces the internal space occupancy of the equipment while ensuring the material pushing effect, and further improves the overall processing efficiency.
