Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology, and in particular to a solid-liquid separation device for purifying earthworm protein. Background Technology

[0002] Earthworm protein, a multifunctional protein, possesses various biological activities such as fibrinolysis, anticoagulation, and improvement of microcirculation, and has wide applications and importance in the fields of biomedicine and health products. The quality of its products largely depends on the precision of the purification process.

[0003] In the entire process of earthworm protein purification, solid-liquid separation is a crucial step. It not only directly affects the efficiency and purity of subsequent protein extraction, but also plays a decisive role in raw material utilization and production cost control.

[0004] Currently, solid-liquid separation in the purification process of earthworm protein mainly relies on a single separation method, such as centrifugation. While this method can achieve initial and rapid separation of materials using the centrifugal force generated by high-speed rotation, it is often insufficient for high-viscosity materials or situations where liquids are tightly adhered to solid particles, resulting in a significant amount of liquid remaining in the solid phase. This situation increases the difficulty of subsequent purification processes and may affect the quality and yield of the final product. Utility Model Content

[0005] To overcome the aforementioned drawbacks, this invention provides a solid-liquid separation device for purifying earthworm protein.

[0006] The technical implementation scheme of this utility model is as follows: a solid-liquid separation device for purifying earthworm protein, comprising a base frame, a cylinder, a rotating cover, a filter cylinder, a water outlet pipe, a valve, a second electric push rod, a squeezing plate, a power assembly, and an opening and closing assembly. The cylinder is connected to the top of the base frame, and the rotating cover is rotatably connected to the left side of the cylinder. The filter cylinder is rotatably connected to the inside of the cylinder, forming a chamber structure between the filter cylinder and the inner wall of the cylinder. The outer wall of the filter cylinder is evenly and densely perforated along the circumference. The water outlet pipe is installed at the bottom of the cylinder through a detachable sealed connection, and the water outlet pipe communicates with the internal chamber of the cylinder. A valve is installed on the water outlet pipe. The second electric push rod is installed on the right side of the cylinder, and the squeezing plate is connected to the telescopic rod of the second electric push rod. The squeezing plate is connected to the right end of the filter cylinder through a sealed movable connection. The cylinder is equipped with a power assembly and an opening and closing assembly.

[0007] More preferably, the power assembly includes a large gear, a motor, and a small gear. The motor is installed on the bottom right side of the cylinder, and the small gear is connected to the output shaft of the motor. The large gear is connected to the outer side of the right end of the filter cylinder, and the large gear is partially exposed outside the device and meshes with the small gear.

[0008] More preferably, the opening and closing assembly includes a support frame, a first electric push rod, and a push rod. The support frame is connected to the top left side of the cylinder. The first electric push rod is mounted on the support frame by a rotatable connection. The end of the telescopic rod of the first electric push rod is connected to the push rod, and the push rod is rotatably connected to the left side of the rotating cover.

[0009] More preferably, it also includes a filter screen, with the filter screen connected to the upper side of the water outlet pipe.

[0010] More preferably, it also includes a top rod, a lifting frame, and a spring. The lifting frame is slidably connected to the upper side of the cylinder, and multiple top rods are connected at intervals to the bottom of the lifting frame. The outer diameter of the top rod is adapted to the inner diameter of the filter holes on the filter cylinder. Springs are connected between the left and right ends of the lifting frame and the cylinder.

[0011] More preferably, the bottom surface of the top rod is designed to be arc-shaped.

[0012] Compared with existing technologies, this utility model has the following advantages: 1. It adopts a dual mechanism of "centrifugal separation + extrusion separation". First, the filter cylinder is driven by a motor to rotate at high speed, and centrifugal force is used to achieve rapid preliminary separation of materials; then, the second electric push rod drives the extrusion plate to apply pressure to the solid material, further extracting the residual liquid. The dual separation works in synergy, which greatly shortens the overall separation time. Compared with a single separation method, the efficiency is significantly improved, meeting the high-efficiency production requirements of earthworm protein purification.

[0013] 2. In the filter hole anti-clogging component, the push rod is inserted into the filter hole of the filter cylinder, and the bottom surface of the push rod adopts an arc-shaped design. During the rotation of the filter cylinder, it can circulate and clean the blockage in the filter hole, reduce frictional resistance, avoid damage to the filter hole, ensure that the filter hole of the filter cylinder is continuously unobstructed, maintain the stable and efficient operation of the equipment, eliminate the need for frequent shutdowns to clean the filter hole, and improve the efficiency of equipment use.

[0014] 3. The filter screen installed in the outlet pipe can perform secondary filtration on the liquid after solid-liquid separation, intercepting residual solid particles in the liquid, effectively ensuring the purity of the discharged liquid, providing high-quality liquid raw materials for the subsequent earthworm protein purification process, and reducing the interference of impurities in subsequent processing steps.

[0020] Example: A solid-liquid separation device for purifying earthworm protein, such as... Figures 1-3 As shown, the system includes a base frame 1, a cylinder 2, a rotating cover 6, a filter cylinder 7, a water outlet pipe 11, a valve 12, a second electric push rod 14, a squeezing plate 15, a power assembly, and an opening and closing assembly. The cylinder 2 is connected to the top of the base frame 1. The rotating cover 6 is rotatably connected to the left side of the cylinder 2 to realize the opening and closing function. The filter cylinder 7 is rotatably connected inside the cylinder 2, forming a chamber structure between the filter cylinder 7 and the inner wall of the cylinder 2. The outer wall of the filter cylinder 7 has filter holes evenly and densely distributed along the circumference to achieve liquid filtration in the solid-liquid separation process. The bottom of the cylinder 2 is connected by a detachable sealing connection. A water outlet pipe 11 is installed in the connection method, which is connected to the internal cavity of the cylinder 2. A valve 12 is installed on the water outlet pipe 11 to control the discharge of liquid. A second electric push rod 14 is installed on the right side of the cylinder 2. A squeezing plate 15 is connected to the telescopic rod of the second electric push rod 14. The squeezing plate 15 and the right end of the filter cylinder 7 are connected in a sealed movable manner to ensure that the liquid in the material can be discharged through the filter hole of the filter cylinder 7 during the squeezing process, while preventing the material from leaking from the connection between the squeezing plate 15 and the filter cylinder 7. The cylinder 2 is equipped with a power assembly and an opening and closing assembly.

[0021] like Figures 2-3 As shown, the power assembly includes a large gear 8, a motor 9, and a small gear 10. The motor 9 is bolted to the bottom right side of the cylinder 2, and the small gear 10 is connected to the output shaft of the motor 9. The large gear 8 is connected to the outer side of the right end of the filter cylinder 7. The large gear 8 is partially exposed outside the device and meshes with the small gear 10. The motor 9 drives the small gear 10 to rotate. By utilizing the gear meshing transmission principle, the large gear 8 and the filter cylinder 7 are driven to rotate at high speed to achieve solid-liquid separation of materials.

[0022] like Figure 1As shown, the opening and closing assembly includes a support frame 3, a first electric push rod 4, and a push rod 5. The support frame 3 is bolted to the top left side of the cylinder 2. The first electric push rod 4 is mounted on the support frame 3 via a rotatable connection. The push rod 5 is connected to the end of the telescopic rod of the first electric push rod 4. The push rod 5 is rotatably connected to the left side of the rotating cover 6. By activating the first electric push rod 4, its telescopic rod is shortened, and the first electric push rod 4 rotates around the support frame 3. At the same time, the push rod 5 pulls the rotating cover 6 to rotate outward around the cylinder 2 and open it. After the rotating cover 6 is fully opened, the earthworm protein material to be purified is added into the filter cylinder 7. After the material is loaded, the telescopic rod of the first electric push rod 4 is extended and reset, pushing the rotating cover 6 to reverse and close, ensuring that a sealed connection is formed between the rotating cover 6 and the cylinder 2 to prevent material leakage during equipment operation.

[0023] During the solid-liquid separation process for earthworm protein purification, the rotating cover 6 is first opened by the first electric push rod 4, allowing the material to be added into the filter cylinder 7. Then, the rotating cover 6 is closed, and the motor 9 is started. The filter cylinder 7 rotates at high speed via the transmission of the small gear 10 and the large gear 8. Under centrifugal force, the solid particles in the material are thrown towards the inner wall of the filter cylinder 7, while the liquid phase flows out through the filter holes on the filter cylinder 7 and enters the chamber between the filter cylinder 7 and the cylinder body 2, achieving preliminary solid-liquid separation. After the preliminary solid-liquid separation is completed, the motor 9 is turned off to stop the rotation of the filter cylinder 7. The second electric push rod 14 is then started, extending its telescopic rod and driving the extrusion plate 15 to move to the left along the inner wall of the filter cylinder 7, extruding the solid material inside the filter cylinder 7. During the extrusion process, the residual liquid in the material is further discharged through the filter holes under the extrusion pressure, improving the solid-liquid separation effect. After extrusion, the first electric push rod 4 is restarted, and the rotating cover 6 is opened. At this time, the second electric push rod 14 continues to extend, and the extrusion plate 15 pushes the solid material in the filter cylinder 7 to the left for collection. After collection, the extension rod of the second electric push rod 14 is controlled to shorten and reset, driving the extrusion plate 15 to move to the right and return to the initial position. Finally, the valve 12 is turned to open it, allowing the liquid in the chamber of cylinder 2 to be discharged through the water outlet pipe 11, completing the entire solid-liquid separation process for earthworm protein purification.

[0024] like Figure 2 As shown, it also includes a filter screen 13. The filter screen 13 is connected to the upper side of the water outlet pipe 11. When the valve 12 is opened to discharge the liquid after solid-liquid separation in the cylinder 2, the filter screen 13 can trap the residual solid particles in the liquid, realizing secondary filtration of the liquid, thereby effectively ensuring the purity of the discharged liquid. After the equipment completes its operation, the water outlet pipe 11 can be disassembled to clean the solid impurities trapped on the filter screen 13 for the next use.

[0025] like Figure 1 , Figure 2 and Figure 4As shown, it also includes a top rod 16, a lifting frame 17, and a spring 18. The lifting frame 17 is slidably connected to the upper side of the inner cylinder 2. Multiple top rods 16 are welded at intervals to the bottom of the lifting frame 17. The outer diameter of the top rod 16 is adapted to the inner diameter of the filter holes on the filter cylinder 7. The bottom surface of the top rod 16 is designed to be arc-shaped, which makes it smoother when in contact with the edge of the filter holes of the filter cylinder 7, and can cut into the filter holes with less resistance. Springs 18 are connected between the left and right ends of the lifting frame 17 and the cylinder 2.

[0026] When the filter cylinder 7 rotates at high speed under the drive of the motor 9 to perform solid-liquid separation, as the filter cylinder 7 rotates, the filter holes on the filter cylinder 7 successively contact the top rod 16 and push the top rod 16, causing the lifting frame 17 to move upward against the elastic force of the spring 18. At this time, the spring 18 is stretched. When the filter cylinder 7 rotates to the next filter hole aligned with the top rod 16, the spring 18 releases its elastic potential energy, pushing the lifting frame 17 and the top rod 16 to move downward and reset, so that the top rod 16 is inserted into the corresponding filter hole. Through the continuous rotation of the filter cylinder 7, the top rod 16 can repeatedly insert and connect with each filter hole, effectively removing solid particles that may clog the filter holes, ensuring the unobstructed flow of the filter holes on the filter cylinder 7, and maintaining the high efficiency of solid-liquid separation.
