Description

Technical Field

[0001] The invention relates to the technical field of material extrusion and filtration equipment, and in particular to a special extrusion and filtration device for biological product materials. Background Art

[0002] Biological products refer to medicines prepared from biological materials such as microorganisms, cells, and various animal and human tissues and fluids obtained through ordinary or genetic engineering, cell engineering, protein engineering, fermentation engineering and other biotechnologies, and used for the prevention, treatment and diagnosis of human diseases. Extrusion filtration is one of the important links in the production of biological products. It removes the filter residue and leaves only the filtrate, and finally the required biological products are extracted from the filtrate.

[0003] However, the existing biological material extrusion filtration equipment has low filtration efficiency. The filtrate squeezed out of the biological material at a higher position can easily penetrate into the material below and cause waste. The safety level is poor. It is impossible to conveniently observe the force of the extrusion filtration, and it is impossible to avoid equipment damage when increasing the extrusion force. The position of the material cannot be changed during the extrusion filtration process, and the balanced extrusion filtration of materials at different positions cannot be guaranteed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting the following technical solution: the extrusion and filtration device for biological product materials described in the present invention comprises an outer frame, and the outer portion of the outer frame is provided with: A material receiving tray, which is slidably connected to one side of the outer frame, and a transverse plate arranged at the bottom of the material receiving tray, the bottom of the transverse plate is fixedly connected to a hydraulic cylinder, the bottom of the hydraulic cylinder is fixedly connected to the top of the outer frame, and a circular filter screen is installed at the bottom of the material receiving tray, and the circular filter screen passes through the material receiving tray; A force-bearing plate, which is evenly installed on the inner wall of the material tray, and the force-bearing plate is an elastic plate, and arc-shaped filter screens are installed at positions close to the force-bearing plate and the material tray, and the arc-shaped filter screens penetrate the force-bearing plate and the material tray; An extrusion plate is evenly installed on the inner part of the material holding tray near the force plate, a bracket is installed on the top of the outer frame, a longitudinal tube is installed on the bottom of the bracket, an inclined spring plate is fixedly connected to the top of the extrusion plate, and one end of the top of the inclined spring plate is fixedly connected to the longitudinal tube, which can ensure that the filtrate is filtered out from the side and bottom at the same time during the extrusion filtration of the biological material, avoiding the problem that the filtrate at the top needs to gradually penetrate downward through a certain height of material before it can be discharged after being squeezed out, reducing the waste caused by the filtrate at the extrusion point re-penetrating into the material when passing through the material, accelerating the filtration efficiency, and reducing the loss of extrusion filtration of the biological material.

[0005] Preferably, an inner push spring is fixedly connected to one side of the force-bearing plate, and the end of the inner push spring away from the force-bearing plate is fixedly connected to the material holding plate, which can evenly disperse the material at the top after completing a single extrusion filtration, avoiding the material always being located at the bottom and the filtrate being squeezed from above with too high water content, thereby improving the balance of material extrusion filtration.

[0006] Preferably, the bottom of the bracket is rotatably connected to a rotating rod, and a traction rope is evenly installed at the bottom of the rotating rod. The bottom of the traction rope is fixedly connected to a driving ball, and the driving ball is slidably connected to the extrusion plate, which improves the visualization of the extrusion and filtration force. The magnitude of the extrusion and filtration force can be directly judged by observing the rotation speed of the driving ball, thereby avoiding damage to the equipment due to excessive extrusion force, improving the safety of equipment use, and extruding and filtering the biological material in a variety of ways such as impact and pressing, thereby improving the extrusion and filtration effect of the biological material.

[0007] Preferably, a driving motor is fixedly connected to the top of the bracket, and the output end of the driving motor passes through the bracket and is fixedly connected to the rotating rod. An annular groove is provided at the top of the outer frame below the material receiving tray, and a drainage groove is provided on one side of the annular groove. A water blocking ball is rotatably connected to the inner bottom of the drainage groove, and one side of the water blocking ball is flat. A handle is fixedly connected to the top of the water blocking ball, which is convenient for collecting and storing the filtrate and reduces the difficulty of storing the filtrate.

[0008] Preferably, both sides of the inner wall of the drainage trough are rotatably connected with a slow flow plate, one side of the slow flow plate is fixedly connected with an elastic rope, and one end of the elastic rope away from the slow flow plate is fixedly connected to the inner wall of the drainage trough, the side of the extrusion plate away from the force plate is fixedly connected with a downward pressing inclined plate, and the side of the extrusion plate away from the downward pressing inclined plate is fixedly connected to a limiting inclined plate, and the driving ball is slidably connected to the limiting inclined plate, and the limiting inclined plate blocks the driving ball from rising to an excessively high position along the extrusion plate during the rotation process, ensuring that the driving ball always slides on the side of the extrusion plate, and the extrusion plate drives the downward pressing inclined plate to move at the same time when the extrusion plate moves to extrude the material, and during the movement of the downward pressing inclined plate, the material is squeezed and compacted obliquely downward, and then the squeezed and compacted material is pushed to move and the material close to the force plate is pushed upward, which can improve the balance of the extrusion of the biological material, and during the extrusion process, the biological material at the bottom is controlled to move to a higher position to avoid the filtrate infiltration of some biological materials that are always at the bottom squeezed by the upper part and contain more water.

[0009] Preferably, a cleaning block is slidably connected to the inner bottom of the annular groove, an elastic reset rope is fixedly connected to the top of the cleaning block, and one end of the elastic reset rope away from the cleaning block is fixedly connected to the outer frame.

[0010] The present invention provides a special extrusion filtration device for biological product materials. It has the following beneficial effects: 1. The extrusion filtration device for biological product materials drives the rotating rod to rotate through the driving motor, and the rotating rod drives the driving ball to rotate. During the rotation of the driving ball, it gradually moves toward the extrusion plate under the action of centrifugation, until the driving ball pushes the extrusion plate to move toward the force plate, and the biological material between the extrusion plate and the force plate is squeezed, and the liquid inside the biological material drips to the outside of the material receiving tray after coming out through the arc filter screen and the circular filter screen, which can ensure that the filtrate is filtered out from the side and the bottom at the same time during the extrusion filtration of the biological material, avoiding the problem that the filtrate at the top needs to gradually penetrate downward through a certain height of the material before it can be discharged after being squeezed out, reducing the waste caused by the filtrate at the extrusion point re-penetrating into the material when passing through the material, accelerating the filtration efficiency, and reducing the loss of biological material extrusion filtration.

[0011] 2. The extrusion and filtration device for biological products controls the driving motor to speed up the rotation speed. The rotating rod rotates faster to drive the driving ball to rotate faster. The driving ball increases the force of the extrusion plate due to the centrifugal effect to squeeze with greater force, thereby improving the visualization of the extrusion and filtration force. The magnitude of the extrusion and filtration force can be directly judged by observing the rotation speed of the driving ball, avoiding damage to the equipment caused by excessive extrusion force, and improving the safety of equipment use.

[0012] 3. The special extrusion filtration device for biological product materials controls the driving motor to stop working after completing a single extrusion filtration, and the driving ball gradually stops rotating. The extrusion plate is no longer squeezed by the driving ball and moves to the initial position under the elastic force of the inclined spring plate. The biological material between the extrusion plate and the force plate is no longer squeezed by the extrusion plate. The inner push spring pushes the force plate to rotate and tilt to the initial position. During the rotation of the force plate, the extruded material is pushed to move to the middle position of the material holding tray. When extrusion filtration is performed again, the extrusion plate pushes the material to stick to the force plate for extrusion. After completing a single extrusion filtration, the material at the top can be evenly dispersed to avoid the material always being at the bottom and the filtrate permeation water content being too high at the upper squeezed position, thereby improving the balance of material extrusion filtration.

[0013] 4. The extrusion filtration device specially designed for biological product materials first contacts and hits the extrusion plate after the driving ball is driven to rotate by the driving motor, and the biological material on one side of the extrusion plate is hit. Then the driving ball pushes the extrusion plate to move and extrude the biological material. The biological material is extruded and filtered by multiple methods such as impact and pressing, thereby improving the extrusion filtration effect of the biological material.

[0014] 5. The special extrusion and filtration device for biological product materials uses a limiting inclined plate to prevent the driving ball from rising to an excessively high position along the extrusion plate during rotation, thereby ensuring that the driving ball always slides on the side of the extrusion plate. When the extrusion plate moves to extrude the material, it drives the downward pressing inclined plate to move at the same time. During the movement of the downward pressing inclined plate, the material is squeezed and compacted diagonally downward, and then the compacted material is pushed to move and the material close to the force plate is pushed upward, which can improve the balance of the extrusion of the biological material. During the extrusion process, the biological material at the bottom is controlled to move to a higher position, thereby preventing part of the biological material from always being at the bottom and being squeezed by the upper part. The filtrate infiltration contains more water.

[0015] 6. The extrusion filtration device specially designed for biological product materials allows the filtrate squeezed out from the material receiving tray to drip into the annular groove, and the drainage groove is blocked by the water blocking ball. After the extrusion filtration is completed, the handle is turned to drive the water blocking ball to rotate, and the filtrate inside the annular groove flows from the flat side of the water blocking ball through the drainage groove to be discharged, which is convenient for the centralized collection of the filtrate for storage and reduces the difficulty of filtrate storage.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses. Example

[0019] See also Figure 1-Figure 5 The present invention provides a technical solution: a special extrusion and filtration device for biological product materials, comprising an outer frame 1, the outer portion of the outer frame 1 is provided with: A material receiving tray 2, which is slidably connected to one side of the outer frame 1, and a transverse plate 3 is arranged at the bottom of the material receiving tray 2, a hydraulic cylinder 4 is fixedly connected to the bottom of the transverse plate 3, and the bottom of the hydraulic cylinder 4 is fixedly connected to the top of the outer frame 1, and a circular filter screen 5 is installed at the bottom of the material receiving tray 2, and the circular filter screen 5 passes through the material receiving tray 2; A force-bearing plate 6, which is evenly installed on the inner wall of the material tray 2, and is an elastic plate, and an arc filter screen 7 is installed at a position close to the force-bearing plate 6 and the material tray 2, and the arc filter screen 7 passes through the force-bearing plate 6 and the material tray 2; An extrusion plate 9 is evenly installed inside the material receiving tray 2 near the force-bearing plate 6. A bracket 10 is installed on the top of the outer frame 1. A longitudinal tube 11 is installed on the bottom of the bracket 10. An inclined spring plate 12 is fixedly connected to the top of the extrusion plate 9. One end of the top of the inclined spring plate 12 is fixedly connected to the longitudinal tube 11.

[0020] An inner push spring 8 is fixedly connected to one side of the force-bearing plate 6 , and one end of the inner push spring 8 away from the force-bearing plate 6 is fixedly connected to the material holding tray 2 .

[0021] The bottom of the bracket 10 is rotatably connected to a rotating rod 14 , the bottom of the rotating rod 14 is evenly installed with a traction rope 15 , the bottom of the traction rope 15 is fixedly connected to a driving ball 13 , and the driving ball 13 is slidably connected to the extrusion plate 9 .

[0022] A driving motor 16 is fixedly connected to the top of the bracket 10 , and an output end of the driving motor 16 passes through the bracket 10 and is fixedly connected to the rotating rod 14 .

[0023] A cleaning block 25 is slidably connected to the inner bottom of the annular groove 17, and an elastic reset rope 26 is fixedly connected to the top of the cleaning block 25, and one end of the elastic reset rope 26 away from the cleaning block 25 is fixedly connected to the outer frame 1. The cleaning block 25 is pushed to move along the annular groove 17 to clean the inside of the annular groove 17, thereby improving the cleaning degree of the equipment.

[0024] During use, the biological material to be squeezed and filtered is poured into the inside of the material tray 2, and the hydraulic cylinder 4 drives the material tray 2 to rise until the squeezing plate 9 moves to the inside of the material tray 2 and contacts with the bottom of the material tray 2, and the driving motor 16 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the driving ball 13 to rotate. During the rotation of the driving ball 13, it gradually moves toward the squeezing plate 9 under the centrifugal action until the driving ball 13 pushes the squeezing plate 9 to move toward the force plate 6, and the biological material between the squeezing plate 9 and the force plate 6 is squeezed. After the force plate 6 is pushed, the inner push spring 8 is compressed and moved to the vertical direction. After the liquid inside the biological material comes out, it passes through the arc filter 7 and the circular filter 5 and drips to the outside of the material tray 2. During the extrusion and filtration of the biological material, the filtrate can be filtered out from the side and the bottom at the same time, avoiding the problem that the filtrate at the top needs to be squeezed out and gradually penetrates downward through a certain height of the material before it can be discharged, reducing the waste caused by the filtrate at the squeezed position re-penetrating into the material when passing through the material, accelerating the filtration efficiency, and reducing the loss of biological material extrusion filtration.

[0025] When it is necessary to speed up the filtration, the driving motor 16 is controlled to increase the rotation speed. After the rotating rod 14 rotates faster, it drives the driving ball 13 to rotate faster. The driving ball 13 increases the force of pushing the extrusion plate 9 due to the centrifugal effect to squeeze with greater force, thereby improving the visualization of the extrusion and filtration force. The size of the extrusion and filtration force can be directly judged by observing the rotation speed of the driving ball 13, avoiding damage to the equipment caused by excessive extrusion force, and improving the safety of equipment use.

[0026] After completing a single extrusion filtration, the control driving motor 16 stops working, the driving ball 13 gradually stops rotating, and the extrusion plate 9 is no longer squeezed by the driving ball 13 and moves to the initial position under the elastic force of the inclined spring plate 12. The biological material between the extrusion plate 9 and the force-bearing plate 6 is no longer squeezed by the extrusion plate 9. The inner push spring 8 pushes the force-bearing plate 6 to rotate and tilt to the initial position. During the rotation of the force-bearing plate 6, the extruded material is pushed to move to the middle position of the material holding tray 2. When extrusion filtration is performed again, the extrusion plate 9 pushes the material to stick to the force-bearing plate 6 for extrusion, which can evenly disperse the material at the top after completing a single extrusion filtration, avoiding the material always being at the bottom and being squeezed by the upper part. The filtrate penetration water content is too high, thereby improving the balance of material extrusion filtration.

[0027] After being driven to rotate by the driving motor 16, the driving ball 13 first contacts and hits the extrusion plate 9, and the biological material on one side of the extrusion plate 9 is hit. Then the driving ball 13 pushes the extrusion plate 9 to move and extrude the biological material. The biological material is extruded and filtered by multiple methods such as impact and pressing, thereby improving the effect of extrusion and filtration of the biological material. Example

[0028] See also Figure 1-Figure 7The present invention provides a technical solution: on the basis of Example 1, an annular groove 17 is provided at the top of the outer frame 1 below the material holding tray 2, a drainage groove 18 is provided on one side of the annular groove 17, a water blocking ball 19 is rotatably connected to the inner bottom of the drainage groove 18, one side of the water blocking ball 19 is a plane, and a handle 20 is fixedly connected to the top of the water blocking ball 19.

[0029] Both sides of the inner wall of the drainage groove 18 are rotatably connected with a slow flow plate 21 , one side of the slow flow plate 21 is fixedly connected with an elastic rope 22 , and one end of the elastic rope 22 away from the slow flow plate 21 is fixedly connected to the inner wall of the drainage groove 18 .

[0030] A side of the extrusion plate 9 away from the force-bearing plate 6 is fixedly connected to a downward pressing inclined plate 23 , and a side of the extrusion plate 9 away from the downward pressing inclined plate 23 is fixedly connected to a limiting inclined plate 24 , and the driving ball 13 is slidably connected to the limiting inclined plate 24 .

[0031] When in use, the limiting inclined plate 24 prevents the driving ball 13 from rising to an excessively high position along the extrusion plate 9 during the rotation process, thereby ensuring that the driving ball 13 always slides on the side of the extrusion plate 9. When the extrusion plate 9 moves to extrude the material, it drives the downward pressing inclined plate 23 to move at the same time. During the movement of the downward pressing inclined plate 23, the material is squeezed and compacted diagonally downward, and then the squeezed and compacted material is pushed to move and the material close to the force-bearing plate 6 is pushed upward, which can improve the balance of the extrusion of the biological material. During the extrusion process, the biological material at the bottom is controlled to move to a higher position, thereby preventing part of the biological material from always being in the bottom where the filtrate is squeezed from the upper part and containing more water.

[0032] The filtrate squeezed out from the material receiving tray 2 drips into the annular groove 17, and the drainage groove 18 is blocked by the water blocking ball 19. After the extrusion filtration is completed, the handle 20 is turned to drive the water blocking ball 19 to rotate, and the filtrate inside the annular groove 17 flows from the plane side of the water blocking ball 19 through the drainage groove 18 to be discharged, which is convenient for the centralized collection of the filtrate for storage and reduces the difficulty of filtrate storage.

[0033] When the filtrate passes through the drainage trough 18, it is blocked by the slow flow plate 21 to reduce the flow speed. After being pushed by the filtrate, the slow flow plate 21 stretches and deflects the elastic rope 22 for buffering, which can avoid splashing caused by excessive flow speed when the filtrate is discharged and collected.

[0034] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
