Description

Technical Field

[0001] This utility model belongs to the field of polymer material processing technology, specifically relating to a hydrophilic and antifouling modification device for polyethersulfone hemodialysis membranes. Background Technology

[0002] Polyethersulfone (PES) is a thermoplastic polymer with excellent comprehensive properties, including superior heat resistance, physical and mechanical properties, and insulation properties. In the application of hemodialysis membranes, PES is widely used as a biomedical membrane material due to its good thermal stability, mechanical strength, chemical stability, and spinnability. In addition, the pore size and pore size distribution of PES materials can be controlled by adjusting the composition of the spinning solution, which makes it important for applications in medical fields such as hemodialysis. The hydrophilic and antifouling modification of PES hemodialysis membranes can be achieved through blending modification, which can significantly improve the hydrophilicity, antifouling properties, and protein retention rate of PES dialysis membranes.

[0003] When performing blending modification of polyethersulfone hemodialysis membranes, the traditional method requires the experimenter to hold a three-necked flask and shake it to mix. This mixing method is inconvenient and prone to being dropped.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a hydrophilic and antifouling modification device for polyethersulfone hemodialysis membranes.

[0005] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a hydrophilic and antifouling modification device for polyethersulfone hemodialysis membranes to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A hydrophilic and antifouling modification device for polyethersulfone hemodialysis membranes includes:

[0009] The installation mechanism includes a first mounting base and a second mounting base fixedly connected to one end of the first mounting base. A movable component is provided on the upper surface of the second mounting base, and a base is provided on the upper surface of the movable component. A receiving chamber is fixedly connected to the upper surface of the base, and a receiving groove is provided in the receiving chamber, in which a beaker is placed.

[0010] A mixing mechanism includes a reciprocating motor fixedly mounted on a first mounting base. The output end of the reciprocating motor is connected to a drive shaft, and a gear is fixedly connected to the drive shaft. Several tooth blocks are fixedly connected to the peripheral side of the base, and the tooth blocks mesh with the gear.

[0011] Preferably, the movable component includes a movable column fixedly connected to the lower surface of the base and a bearing mounted on the upper surface of the second mounting base, wherein the movable column is rotatably engaged with the second mounting base via the bearing.

[0012] Preferably, a motor parameter control panel is fixedly mounted on the front surface of the first mounting base, and the motor parameter control panel is electrically connected to the reciprocating motor.

[0013] Preferably, the beaker has a plurality of branch tubes on its circumferential side, the number of which is three. The branch tubes are connected to the beaker and a sealing plug is provided at one end of each branch tube.

[0014] Preferably, the accommodating compartment is provided with positioning cylinders on its periphery, and there are two positioning cylinders. The positioning cylinders have threaded holes inside, and positioning screws are screwed into the threaded holes.

[0015] Preferably, a rubber positioning post is slidably connected inside the threaded hole, one end of the rubber positioning post is in contact with the positioning screw, and the other end of the rubber positioning post is in a compression fit with the beaker.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) By setting up a receiving chamber with a receiving groove, when it is necessary to perform a blending modification operation on the polyethersulfone hemodialysis membrane, the required blending material solution can be poured into the beaker from the three branch tubes respectively. After locking and fixing the beaker, the reciprocating motor can be started to drive the gear to reciprocate at a certain frequency. Then, the gear can drive the top beaker to reciprocate through its meshing with the tooth block, so that the liquid in the beaker can be fully blended. Thus, there is no need for the experimenter to shake manually, and the blending effect is more uniform.

[0018] (2) This utility model provides a positioning cylinder with positioning screws and rubber positioning pins. The beaker is placed in the receiving groove. At this time, the positioning screws can be rotated to squeeze the rubber positioning pins. Then the rubber positioning pins slide into the threaded hole to provide squeezing and positioning measures for the beaker. The soft material of the rubber positioning pins can avoid damaging the beaker.

Detailed Implementation

[0025] 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.

[0026] Example 1:

[0027] Please see Figures 1-4 As shown, a hydrophilic and antifouling modification device for a polyethersulfone hemodialysis membrane includes:

[0028] The installation mechanism includes a first mounting base 1 and a second mounting base 2 fixedly connected to one end of the first mounting base 1. A movable component is provided on the upper surface of the second mounting base 2, and a base 5 is provided on the upper surface of the movable component. A receiving chamber 6 is fixedly connected to the upper surface of the base 5. A receiving groove 7 is opened in the receiving chamber 6, and a beaker 8 is placed in the receiving groove 7.

[0029] The mixing mechanism includes a reciprocating motor 13 fixedly mounted on the first mounting base 1. The output end of the reciprocating motor 13 is connected to a drive shaft 14. A gear 15 is fixedly connected to the drive shaft 14. Several tooth blocks 16 are fixedly connected to the periphery of the base 5. The tooth blocks 16 mesh with the gear 15.

[0030] Specifically, the movable component includes a movable column 4 fixedly connected to the lower surface of the base 5 and a bearing 18 mounted on the upper surface of the second mounting base 2. The movable column 4 is rotatably engaged with the second mounting base 2 through the bearing 18.

[0031] Specifically, a motor parameter control panel 3 is fixedly mounted on the front surface of the first mounting base 1. The motor parameter control panel 3 is electrically connected to the reciprocating motor 13 and is used to control the opening and closing, speed and rotation mode of the reciprocating motor 13.

[0032] Specifically, the beaker 8 has several branch tubes 9 on its sides. There are three branch tubes 9, which are connected to the beaker 8. A sealing plug 17 is provided at one end of each branch tube 9.

[0033] As can be seen from the above, this device, by setting up a receiving chamber 6 with a receiving tank 7, allows the required blending solution to be poured into beaker 8 from the three branch pipes 9 when it is necessary to perform blending modification on the polyethersulfone hemodialysis membrane. After locking and fixing the beaker 8, the reciprocating motor 13 can be started to drive the gear 15 to reciprocate at a certain frequency. In turn, the gear 15, through its meshing with the tooth block 16, can drive the top beaker 8 to reciprocate, thereby fully blending the liquid in the beaker 8. This eliminates the need for manual shaking by the experimenter, and the blending effect is more uniform.

[0034] Example 2:

[0035] Please see Figures 1-4 As shown, two positioning cylinders 10 are provided on the sides of the 6-sided container. The positioning cylinders 10 have threaded holes 11 inside, and positioning screws 12 are screwed into the threaded holes 11.

[0036] Specifically, a rubber positioning post is slidably connected inside the threaded hole 11. One end of the rubber positioning post is in contact with the positioning screw 12, and the other end of the rubber positioning post is in a compression fit with the beaker 8.

[0037] As can be seen from the above, this device uses a positioning cylinder 10 with a positioning screw 12 and a rubber positioning post to place the beaker 8 in the receiving groove 7. At this time, the positioning screw 12 can be rotated to squeeze the rubber positioning post, and then the rubber positioning post slides into the threaded hole 11 to provide a squeezing positioning measure for the beaker. Moreover, the soft material of the rubber positioning post can avoid damaging the beaker 8.
