Description

Technical Field

[0001] This utility model belongs to the field of clamp technology, specifically relating to a convenient ultrafiltration clamp. Background Technology

[0002] When extracting urokinase, urinary gonadotropins and other urinary proteins from human urine, ultrafiltration technology is required to concentrate the urine to a specified volume. During the ultrafiltration process, an ultrafiltration membrane is needed to filter and concentrate the urine, and an ultrafiltration membrane packing clamp is used to fix the ultrafiltration membrane packing during ultrafiltration.

[0003] For example, Chinese patent CN221673910U discloses an ultrafiltration membrane pack clamp, comprising: a membrane pack cavity; clamping plates respectively disposed on both sides of the membrane pack cavity; a connecting member penetrating the membrane pack cavity, with both ends of the connecting member extending outward and fixedly connected to the clamping plates; and locking members disposed at both ends of the connecting member; the membrane pack cavity comprises several sets of stacked and assembled components, with the remaining components correspondingly disposed one-to-one, and the membrane pack placed in the area formed between the clamping plates and the membrane pack cavity; the connecting member comprises several screws symmetrically distributed on the membrane pack cavity; the locking member sequentially comprises a gasket disposed close to the clamping plates, a first nut disposed close to the gasket, and a second nut disposed close to the first nut. This utility model provides an ultrafiltration membrane pack clamp with advantages such as high working efficiency, simple structure, convenient assembly and disassembly, and convenient operation. This device uses clamps on both sides of the membrane pack cavity and connectors to fix the clamp positions, allowing membrane packs to be installed on both sides of the membrane pack cavity. It can also accommodate multiple membrane packs by stacking the membrane pack cavity. However, the locking components on both sides need to be pressurized and locked separately, requiring a secondary operation. When the number of membrane packs stacked on one side is too large, it is equivalent to the function of a regular membrane pack clamp. Moreover, as the number of stacked membrane packs increases, the clamping force required also increases. The pressure between each membrane pack is not uniform, with greater force near the clamping point and less force far from the clamping point, which is not conducive to the separation efficiency of the membrane packs. Utility Model Content

[0004] To address the problems mentioned above in the background technology, a user-friendly ultrafiltration clamp is provided. By spaced auxiliary clamps between membrane packs and adjusting the clamping force of the auxiliary clamps using screws, the clamping force between multiple membrane packs can be balanced, ensuring separation effect and improving work efficiency while stacking membrane packs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a convenient ultrafiltration clamp, comprising a clamp body, a membrane pack, and silicone gaskets. The clamp body includes a first clamp, and a second clamp is arranged parallel to the upper end of the first clamp. The first clamp and the second clamp are connected around their respective centers by four guide rods, and a pressure component is connected to the top of each guide rod. The membrane pack is located inside the clamp body, and the silicone gaskets are spaced apart between the membrane pack and the clamp body. At least two auxiliary clamps are also provided inside the clamp body to fix the membrane pack to the first clamp and the second clamp respectively. A set of connecting components connecting two adjacent auxiliary clamps is also provided on the front and rear sides of each auxiliary clamp.

[0006] Furthermore, the auxiliary fixture includes a square frame, a sliding seat connected to the front and rear guide rods, an arc-shaped groove that engages with the left and right guide rods, and screw support seats symmetrically arranged on both sides of the sliding seat. The sliding seat is connected to the middle of the front and rear sides of the square frame, and arc-shaped grooves are opened in the middle of the left and right sides of the square frame. The screw support seats are connected to the front and rear sides of the square frame. A deep groove for installing the membrane pack is provided inside the square frame.

[0007] Furthermore, the connecting assembly includes washers, a connecting screw, and a fastening nut. The connecting screw is located between two auxiliary clamps, and two washers close to the auxiliary clamps are fitted on the connecting screw. The washers are fixed to the auxiliary clamps by the fastening nut, which is threadedly connected to the connecting screw, and the auxiliary clamps are clamped and positioned.

[0008] Furthermore, the pressure assembly includes a gasket, a bushing, and a fastening nut. The gasket and bushing are fitted onto the upper end of the guide rod, with the bushing positioned above the gasket. The fastening nut is securely connected to the bushing from the top of the guide rod.

[0009] Furthermore, one of the four guide rods, either on the left or right side, is threadedly connected to the first clamping body, while the other three guide rods are fixed to the first clamping body. The second clamping body is slidably connected to the four guide rods.

[0010] Furthermore, the diameter of the arc-shaped groove is not less than the diameter of the guide rod.

[0011] Furthermore, the first clamp body is provided with a liquid inlet on its side end, and the second clamp body is provided with a liquid outlet on its side end.

[0012] The beneficial effects of this utility model are: 1) This utility model sets two auxiliary clamps and a connecting assembly for fixing the auxiliary clamps between the membrane packs, and fixes the multiple stacked membrane packs between the first clamp, the auxiliary clamps and the second clamp respectively, which is convenient to use. In addition, by tightening the nuts, connecting screws and lead screw support seats, clamping force and support can be applied to the membrane packs above and below the auxiliary clamps. When the pressure component at the top of the second clamp is applied, the pressure between the multiple membrane packs at the bottom is more balanced, which can accelerate the separation and filtration of liquid and improve the ultrafiltration effect.

[0013] 2) By disassembling and connecting a guide rod on the left and right sides of the first clamp, this utility model can facilitate the placement or removal of multiple membrane packs and silicone pads. While stacking multiple membrane packs, it ensures that the installation and disassembly speed is fast and saves time. It also makes it easy to clean the clamps. Moreover, the structure is simple and easy to use. Attached Figure Description

[0020] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0021] Example: Figure 1-5As shown, the present invention provides a convenient ultrafiltration clamp, comprising a clamp body 1, a membrane pack 2, and silicone gaskets 173. The clamp body 1 includes a first clamp 4, with a second clamp 5 arranged parallel to the upper end of the first clamp 4. The first clamp 4 and the second clamp 5 are connected around their respective centers by four guide rods 6, with a pressure assembly 7 connected to the top of each guide rod 6. The membrane pack 2 is located inside the clamp body 1, and the silicone gaskets 173 are spaced apart between the membrane pack 2 and the clamp body 1. At least two auxiliary clamps 8 are also provided inside the clamp body 1 to fix the membrane pack 2 onto the first clamp 4 and the second clamp 5 respectively. A set of connecting assemblies 9 connecting adjacent auxiliary clamps 8 is also provided on the front and rear sides of the auxiliary clamps 8. The first clamp 4 has a liquid inlet on its side, and the second clamp 5 has a liquid outlet on its side.

[0022] See Figure 5 In this embodiment, the auxiliary clamp 8 includes a square frame 10, a sliding seat 11 connected to the front and rear guide rods 6, an arc-shaped groove 12 engaged with the left and right guide rods 6, and screw support seats 13 symmetrically arranged on both sides of the sliding seat 11. The sliding seat 11 is connected to the middle of the front and rear sides of the square frame 10. The arc-shaped groove 12 is opened in the middle of the left and right sides of the square frame 10. The screw support seats 13 are connected to the front and rear sides of the square frame 10. A deep groove for installing the membrane pack 2 is provided inside the square frame 10.

[0023] The connecting assembly 9 includes washers 14, connecting screws 15, and fastening nuts 16. The connecting screws 15 are located between the two auxiliary clamps 8. Two washers 14 close to the auxiliary clamps 8 are fitted on the connecting screws 15. The washers 14 are fixed on the auxiliary clamps 8 by the fastening nuts 16 that are threaded to the connecting screws 15, and the auxiliary clamps 8 are clamped and positioned.

[0024] See Figure 4 In this embodiment, the pressure assembly 7 includes a gasket 17, a bushing 18, and a fastening nut 16. The gasket 17 and the bushing 18 are sleeved on the upper end of the guide rod 6, with the bushing 18 located above the gasket 17. The fastening nut 16 is fastened to the bushing 18 from the top of the guide rod 6.

[0025] One of the four guide rods 6, either on the left or right side, is threadedly connected to the first clamp 4, while the other three guide rods 6 are fixed to the first clamp 4. The second clamp 5 is slidably connected to the four guide rods 6. In use, after placing the membrane pack 2, the second clamp 5 is fitted onto the four guide rods 6 from the top and secured by the pressure assembly 7 to perform the ultrafiltration process.

[0026] The diameter of the arc-shaped groove 12 is not less than the diameter of the guide rod 6. In use, the guide rod 6 can be snapped into the arc-shaped groove 12 to position the membrane pack 2, the silicone gasket 173 and the auxiliary clamp 8, preventing misalignment or displacement during installation and affecting the ultrafiltration effect.

[0027] When using the ultrafiltration fixture of this embodiment, refer to Figure 5 Taking the left guide rod 6 as an example (without installation), the right, front, and rear guide rods 6 are all installed on the first clamp 4. At this point, the three auxiliary clamps 8 are initially installed on the guide rods 6 at intervals, and initially positioned using the connecting assembly 9. Then, the membrane pack 2 and silicone pads 173 are placed at the lower end of the auxiliary clamps 8. Specifically, the silicone pads 173 are placed from left to right, followed by the membrane pack 2, and so on, ensuring that the silicone pads 173 are always in contact with the first clamp 4 and the auxiliary clamps 8, with the membrane pack 2 positioned between the silicone pads 173. (Reference) Figure 1 and Figure 2 After placing three membrane packs 2 below the auxiliary clamp 8, adjust the fastening nut 16 on the connecting screw 15 to clamp the three membrane packs 2 and silicone gasket 173 below using the auxiliary clamp 8. Then, place three more membrane packs 2 and silicone gasket 173 above the auxiliary clamp 8. Continue to clamp the connecting component 9 at the upper end of the auxiliary clamp 8. Finally, place the second clamp 5 at the top, allowing it to fit onto the three guide rods 6. Then, install the left guide rod 6 and thread it onto the first clamp 4. Finally, tighten the pressure component 7 to press the auxiliary clamp 8 and the first clamp 4 together, completing the installation process. During ultrafiltration, liquid is introduced through the inlet at the lower end and discharged through the outlet at the upper end. Conversely, during disassembly, first remove the second clamp 5 and the left guide rod 6, then loosen the connecting component 9 on the auxiliary clamp 8. The membrane packs 2 and silicone gasket 173 can then be removed from the left opening without separate operation, saving time.

[0028] This invention utilizes two auxiliary clamps and a connecting assembly for fixing the auxiliary clamps between the membrane packs. Multiple stacked membrane packs are secured between a first clamp, the auxiliary clamps, and the second clamp, making it convenient to use. By tightening nuts, connecting screws, and lead screw support seats, clamping force and support can be applied to the membrane packs above and below the auxiliary clamps. When the pressure component at the top of the second clamp applies pressure, the pressure among the multiple membrane packs at the lower end becomes more even, accelerating liquid separation and filtration, and improving the ultrafiltration effect. Furthermore, by detachably connecting a guide rod on the left and right sides of the first clamp, this invention facilitates the placement or removal of multiple membrane packs and silicone gaskets. Even when multiple membrane packs are stacked, the installation and disassembly speed is maintained, saving time and making it easier to clean the clamps. The structure is simple and easy to use.

[0029] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
