Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation and screening, in particular to a solid-liquid separation and screening device. Background Art

[0002] In the vaccine production process, the filler plays an important role in the vaccine purification process. Due to its highly rigid matrix, the filler allows high flow rates and high column bed heights, which, combined with high capacity, is the basis for efficient production. In addition, it exhibits affinity for various viruses, making it a universal filler in the production of different viral vaccines. In order to make the filler reusable, it needs to be cleaned and the preservation solution replaced before each use. During the cleaning process, the filler needs to be separated from the preservation solution, which requires the use of a solid-liquid separation and screening device.

[0003] However, when using the existing solid-liquid separation and screening device, the filler and the preservation solution are poured into a separation screen barrel wrapped with silk cloth, and the gravity of the liquid is used for separation. This method takes a long time for separation. At the same time, since the gravity of the filler itself is greater than the mass of the preservation solution, during the long separation process, the filler will accumulate on the surface of the silk cloth, resulting in a decrease in the gaps on the surface of the silk cloth, affecting the descending speed of the preservation solution, and resulting in slow separation efficiency.

DETAILED DESCRIPTION

[0049] The present invention will be further described below with reference to the accompanying drawings: Example

[0050] See also Figure 1-6In this embodiment, the solid-liquid separation and screening device includes: a shell, a separation screen barrel 3, two groups of bases 21 and a high-efficiency separation device.

[0051] In this embodiment, the housing is composed of a detachable lower shell 1 and an upper shell 2.

[0052] In this embodiment, an electric push rod 13 is provided between the lower shell 1 and the upper shell 2 to push the upper shell 2 to move vertically. A feed port is provided on the upper shell 2, and liquid outlets are provided on both sides of the lower shell 1.

[0053] The separation screen barrel 3 is arranged inside the shell and is used for solid-liquid separation; an inlet is opened on the top of the separation screen barrel 3, and an outlet is opened on the bottom.

[0054] In this embodiment, the surface of the separation screen barrel 3 is wrapped with silk cloth, and a through hole is opened on the separation screen barrel 3. The separation screen barrel 3 is shaped like an inverted funnel, and the outlet shape below the separation screen barrel 3 is square.

[0055] The two sets of bases 21 are arranged below the separation screen barrel 3 to prevent the liquid inside the separation screen barrel 3 from flowing out.

[0056] In this embodiment, the base 21 is made of corrosion-resistant rubber material; the size of the base 21 is larger than the size of the opening and the outlet; by moving the base 21, the opening and the outlet can be connected, so that the filler inside the separation screen barrel 3 falls downward through the opening and the outlet.

[0057] A bottom plate is provided above the base 21, and the edge of the bottom plate is fixedly connected to the lower shell 1. An opening is provided in the center of the bottom plate, and the position of the opening is located directly below the outlet; a high-efficiency separation device is provided inside the shell and is located directly above the separation screen barrel 3, for improving the efficiency of solid-liquid separation.

[0058] In this embodiment, the space above the separation screen barrel 3 can be pressurized by a high-efficiency separation device, thereby increasing the separation speed. At the same time, the filler on the surface of the silk cloth will also be cleaned to prevent the filler from clogging the silk cloth, thereby further improving the separation efficiency.

[0059] like Figure 2 As shown, the high-efficiency separation device includes: an air pressure regulating box 4, a screw 5, a first motor 6, a screw nut 7, a piston 8, an air inlet pipe 9, an air outlet pipe 10, two sets of elastic switches 11, a telescopic part and a scraping part 12.

[0060] Specifically, a cavity is formed inside the air pressure regulating box 4; the lead screw 5 is disposed in the cavity, and both ends of the lead screw 5 pass through corresponding positions of the air pressure regulating box 4 and are rotatably connected to the air pressure regulating box 4.

[0061] In this embodiment, the air pressure regulating box 4 can support the rotation of the lead screw 5 .

[0062] The output end of the first motor 6 is fixedly connected to the top end of the lead screw 5 ; the lead screw nut 7 is arranged on the surface of the lead screw 5 and is threadedly connected to the lead screw 5 .

[0063] In this embodiment, the model of the first motor 6 is selected according to actual needs and meets the working conditions. When the first motor 6 is running, it will drive the screw 5 to rotate, and the screw 5 will cause the screw nut 7 to move vertically. After the screw nut 7 moves to the bottom, as the screw 5 continues to rotate, the screw nut 7 will move upward. This is the structural characteristic of the screw 5 itself.

[0064] The piston 8 is arranged on the edge of the screw nut 7 and is fixedly connected to the screw nut 7; the edge of the piston 8 is tightly fitted with the inner wall of the air pressure regulating box 4; one end of the air inlet pipe 9 is connected to the cavity, and the other end is connected to the outside; one end of the air outlet pipe 10 is connected to the cavity, and the other end is connected to the inside of the shell.

[0065] In this embodiment, the screw nut 7 drives the piston 8 to move. When the piston 8 moves upward, the outside air is drawn into the cavity through the air inlet pipe 9. When the piston 8 moves downward, the air in the cavity is sent to the shell through the air outlet pipe 10, thereby increasing the pressure inside the shell.

[0066] Two sets of elastic switches 11 are respectively arranged at one end of the air inlet pipe 9 and the air outlet pipe 10 away from the cavity; the top of the telescopic member is fixedly connected to the bottom end of the screw 5; the scraping member 12 is arranged at the bottom end of the telescopic member and fixedly connected to the telescopic member.

[0067] In this embodiment, when the screw 5 rotates, the scraping member 12 will be driven to rotate synchronously through the telescopic member. The scraping member 12 will scrape away the filler accumulated on the inner wall of the separation screen barrel 3, thereby reducing the filler thickness on the inner wall of the separation screen barrel 3 and further improving the separation efficiency.

[0068] The elastic switch 11 consists of two groups of parallel blocking plates, two groups of parallel sliding rods and two groups of springs. One end of the two groups of sliding rods is fixedly connected to one group of blocking plates, and the other end passes through the corresponding position of the other group of blocking plates and is fixedly connected to the air pressure regulating box 4; each group of springs is sleeved on the surface of the sliding rod, and the two ends of the spring are respectively fixedly connected to the blocking plate located in the middle position of the sliding rod and the air pressure regulating box 4.

[0069] In this embodiment, when the piston 8 moves upward, the external gas will apply force to the cavity, and the elastic switch 11 located at the air inlet pipe 9 has space to move into the cavity, so that the spring here is stretched and the sealing plate is separated from the air inlet pipe 9, allowing external air to enter the cavity, while the elastic switch 11 located at the air outlet pipe 10 has no space to move into the cavity, so no gap will be generated.

[0070] When the piston 8 moves downward, contrary to the above situation, the internal gas will exert force to the outside, and the elastic switch 11 located at the air inlet pipe 9 has no space to move to the outside of the cavity, so that the spring here will not be stretched, while the elastic switch 11 located at the air outlet pipe 10 has space to move to the outside of the cavity, so it will stretch the spring here and make the sealing plate detach from the air outlet pipe 10, so that the air in the cavity enters the shell.

[0071] The scraping member 12 is composed of a transverse plate and two groups of scrapers. The two groups of transverse plates are fixedly connected to the two groups of scrapers. The edges of the scrapers are in contact with the inner wall of the separation screen barrel 3.

[0072] like Figure 2 and Figure 4 As shown, the telescopic member includes a rotating shaft 14 and a sleeve member 15.

[0073] Among them, slideways are opened on both sides of the surface of the rotating shaft 14; a notch is opened on the top of the socket 15, and a slider is set at the position of the notch corresponding to the slideway, and the slider is slidably connected to the rotating shaft 14 through the slideway; so that the rotating shaft 14 can extend to the inside of the socket 15.

[0074] In this embodiment, the sleeve 15 can move vertically along the surface of the rotating shaft 14 by sliding between the slider and the slideway. When the rotating shaft 14 rotates, it drives the sleeve 15 to rotate synchronously through the slider.

[0075] During the separation process, due to the large mass of the filler, it will settle downwards, resulting in incomplete cleaning.

[0076] In order to solve the above problems, this embodiment proposes an implementation method, in which the solid-liquid separation and screening device further includes: an adjusting device; the adjusting device is rotatably connected to the telescopic member and is used to adjust the position of the scraping member 12.

[0077] In this embodiment, Figure 2 、 Figure 3 and Figure 6 As shown, the adjusting device includes: a support plate 16 , an inclined plate 17 , a moving frame 18 , a rotating member 19 and a second motor 20 .

[0078] Specifically, the support plate 16 is rotatably connected to the surface of the sleeve 15 .

[0079] In this embodiment, the support plate 16 can drive the sleeve 15 to move vertically, and the support plate 16 also supports the rotation of the sleeve 15.

[0080] A first cylindrical pin is provided on the surface of the support plate 16 at one end away from the socket 15; a first sliding groove is opened on the surface of the inclined plate 17, so that the first cylindrical pin is set in the first sliding groove, and the inclined plate 17 is slidably connected to the first cylindrical pin through the inner wall of the first sliding groove.

[0081] In this embodiment, when the inclined plate 17 moves horizontally, the support plate 16 moves vertically through the sliding between the first cylindrical pin and the first sliding groove.

[0082] The moving frame 18 is fixedly connected to the side of the inclined plate 17 away from the socket 15; the rotating member 19 is arranged inside the moving frame 18, and the edge of the rotating member 19 is in contact with the inner wall of the moving frame 18; the output end of the second motor 20 is fixedly connected to the axis of the rotating member 19.

[0083] In this embodiment, the model of the second motor 20 is selected according to actual needs and meets the working conditions. When the second motor 20 is running, the output end of the second motor 20 drives the rotating member 19 to rotate. Since the space inside the moving frame 18 is limited, when the rotating member 19 rotates, it will push the moving frame 18 to move horizontally, and the moving frame 18 will also drive the inclined plate 17 to move.

[0084] After the separation is completed, the filler will be retained in the separation screen barrel 3. The existing method of removing the filler requires the separation screen barrel 3 to be disassembled from the shell and then pouring out the filler, which is inconvenient.

[0085] To solve the above problems, this embodiment proposes an implementation method, where the solid-liquid separation and screening device also includes: a moving device; the moving device is arranged below the base 21 and fixedly connected to the base 21, and is used to drive the base 21 to move horizontally.

[0086] In this embodiment, Figure 2 and Figure 5 As shown, the moving device includes: a moving member 22, a rotating rod 23, a connecting member 24, a disc 25 and a turntable handle 26.

[0087] Among them, one end of the moving part 22 is fixedly connected to the base 21; a second cylindrical pin is provided on the side of the surface of the moving part 22 away from the base 21; a second slide groove and a third slide groove are successively opened at both ends of the rotating rod 23, and the rotating rod 23 is slidably connected to the second cylindrical pin through the inner wall of the second slide groove.

[0088] In this embodiment, when the rotating rod 23 rotates, the second cylindrical pin will slide between the second slide groove and the second cylindrical pin, so that the second cylindrical pin drives the moving part 22 to move horizontally, thereby driving the base 21 to move. Since the moving distance of the base 21 is limited and it fits tightly with the bottom plate and the separation screen barrel 3, the preservation solution located on the outside of the separation screen barrel 3 will not penetrate downward from here.

[0089] The connecting member 24 consists of a vertical rod, a third cylindrical pin and a rotating rod. The upper surface of the vertical rod is fixedly connected to the third cylindrical pin; the third cylindrical pin is set in the third slide groove and is slidingly connected to the rotating rod 23 through the third slide groove; one end of the rotating rod is rotatably connected to the vertical rod.

[0090] In this embodiment, when the rotating rod rotates, it will pull the vertical rod and the third cylindrical pin to move horizontally, and the vertical rod will slide between the third cylindrical pin and the third sliding groove, causing the rotating rod 23 to rotate.

[0091] The surface of the disc 25 is rotatably connected to the other end of the rotating rod; the turntable handle 26 is coaxially arranged with the disc 25.

[0092] In this embodiment, the disc 25 is driven to rotate by rotating the turntable handle 26, and the disc 25 will cause the rotating rod to rotate slightly and move horizontally at the same time; the rotating rod simultaneously drives the vertical rod and the third cylindrical pin to move horizontally; the vertical rod will rotate by sliding between the third cylindrical pin and the third slide groove; the rotating rod 23 will slide between the second slide groove and the second cylindrical pin, so that the second cylindrical pin drives the moving member 22 to move horizontally; at this time, the moving direction of the moving member 22 is opposite to the moving direction of the vertical rod; the moving member 22 drives the base 21 to move, thereby opening the opening below the separation screen barrel 3, so that the filler falls into the collection box 27, which is convenient for removing the filler.

[0093] The solid-liquid separation and screening device further includes: a collecting box 27; the collecting box 27 is arranged directly below the bottom plate, and the collecting port of the collecting box 27 corresponds to the position of the opening.

[0094] Working principle:

[0095] When the solid-liquid separation and screening device is in use, a mixed liquid of required filler and preservation solution is added into the separation screen barrel 3 through the feed port on the upper shell 2 .

[0096] Subsequently, the first motor 6 is operated so that the output end of the first motor 6 drives the lead screw 5 to rotate; the lead screw 5 first moves the lead screw nut 7 upward; after reaching the top, the lead screw nut 7 moves downward; the lead screw nut 7 simultaneously drives the piston 8 to move; when the piston 8 moves upward, the external gas will apply force to the cavity; and the elastic switch 11 located at the air inlet pipe 9 has space to move toward the inside of the cavity, so that the spring here is stretched and the sealing plate is separated from the air inlet pipe 9, allowing external air to enter the cavity; and the elastic switch 11 located at the air outlet pipe 10 has no space to move toward the inside of the cavity, so no gap is generated; and when the piston 8 moves downward, contrary to the above situation, the internal The gas will exert force to the outside; the elastic switch 11 located at the air inlet pipe 9 has no space to move to the outside of the cavity, so that the spring here will not be stretched; the elastic switch 11 located at the air outlet pipe 10 has space to move to the outside of the cavity, so it will stretch the spring here and make the sealing plate separate from the air outlet pipe 10, so that the air in the cavity enters the shell, thereby increasing the air pressure above the separation screen barrel 3, and then improving the separation efficiency; at the same time, when the screw 5 rotates, the scraping member 12 will be driven to rotate synchronously through the telescopic member; the scraping member 12 will scrape away the filler accumulated on the inner wall of the separation screen barrel 3, thereby reducing the filler thickness on the inner wall of the separation screen barrel 3, and further improving the separation efficiency.

[0097] After the filler sinks to the bottom, the second motor 20 is operated and the output end of the second motor 20 drives the rotating member 19 to rotate; due to the limited space inside the moving frame 18, when the rotating member 19 rotates, it will push the moving frame 18 to move horizontally toward the direction of the rotating shaft 14; the moving frame 18 also drives the inclined plate 17 to move, and the inclined plate 17 will slide between the first cylindrical pin and the first slide groove, so that the support plate 16 moves vertically upward; the support plate 16 drives the socket 15 to move, so that the socket 15 moves vertically upward along the surface of the rotating shaft 14 by sliding between the slider and the slideway, thereby raising the position of the scraping member 12; it stops after reaching the specified position, and as the screw 5 continues to rotate, the scraping member 12 will play a stirring role; and the purpose of raising the scraping member 12 is to make the stirring position more biased towards the middle position, thereby increasing the stirring force.

[0098] After separation is completed, the separated preservation liquid is discharged through the liquid outlets on both sides of the lower shell 1. Subsequently, the disc 25 is driven to rotate by turning the turntable handle 26. The disc 25 will cause the rotating rod to rotate slightly and move horizontally at the same time; the rotating rod simultaneously drives the vertical rod and the third cylindrical pin to move horizontally; the vertical rod will slide between the third cylindrical pin and the third slide groove, causing the rotating rod 23 to rotate; the rotating rod 23 will slide between the second slide groove and the second cylindrical pin, causing the second cylindrical pin to drive the moving part 22 to move horizontally; at this time, the moving direction of the moving part 22 is opposite to the moving direction of the vertical rod; the moving part 22 drives the base 21 to move, thereby opening the opening below the separation screen barrel 3, allowing the filler to fall into the collection box 27, making it easy to take out the filler, and completing the use of this device.
