Description

Technical Field

[0001] The utility model relates to the technical field of a curing device for injecting polyurethane glue into a dialyzer, in particular to a device for curing a dialyzer at a constant temperature and controlled speed after injecting polyurethane glue. Background Technique

[0002] In a hemodialyzer, the dialysis membrane and the housing material need to be bonded together using a two-component polyurethane glue in some combinations. Glue filling is a key process in the production of dialyzers, that is, injecting the polyurethane glue into the semi-finished dialyzer to fill the space inside the housing, so as to isolate the blood chamber and the dialysate chamber of the dialyzer after glue filling. It is necessary to ensure that all the spaces between the dialysis membrane filaments and the dialyzer housing are completely and absolutely tightly glued together with the polyurethane glue. During the curing process of the polyurethane glue, a curing device is required to ensure the stable curing of the polyurethane glue, provide guarantee for the yield rate of the finished product, and ensure good economic benefits for the enterprise.

[0003] After the two-component polyurethane on the market is mixed, it reacts violently, releases heat and cures, and the temperature is above 80°C. The reaction is fast and the temperature is high, and the bubbles after the reaction are not easy to discharge, resulting in bubbles in the polyurethane glue of the dialyzer, which limits the yield rate of the dialyzer. At the same time, if the dialyzer is placed in a low-temperature environment for curing reaction, the polyurethane glue cures stably, but the time is long, the production efficiency is low, and the cost is high, which is not suitable for large-scale production. Therefore, we propose a device for curing a dialyzer at a constant temperature and controlled speed after injecting polyurethane glue. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for curing a dialyzer at a constant temperature and controlled speed after injecting polyurethane glue, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for curing a dialyzer at a constant temperature and controlled speed after injecting polyurethane glue, including a machine body, a constant temperature box and a fixing jig. A constant temperature deionized water pool is installed at the lower end of the machine body, and ion water conveying pipelines are connected to both ends of the constant temperature deionized water pool. The constant temperature deionized water pool conveys deionized water through the ion water conveying pipeline and a conveying pump.

The middle part of the machine body is communicated with the constant temperature deionized water pool. The upper end of the fixing jig is milled with bosses on both sides, and positioning holes are opened in the middle of both bosses. Friction sliders are welded on both sides of the outer wall of the fixing jig, and the friction sliders are in contact with the outer wall surface of the belt conveyor.

[0006] Preferably, heat exchange fins for heat exchange protection are laid on the inner wall of the heat exchange aluminum plate, and fans are installed at both ends of the heat exchange aluminum plate. Through holes are opened at both ends of the constant temperature box, and the air outlets of the fans are installed on the through holes.

[0007] Preferably, the through holes at both ends of the constant temperature box are connected through pipes, and the constant temperature box and the heat exchange aluminum plate form an air flow constant temperature circulation system through the through holes and pipes.

[0008] Preferably, slide rails are bolted to both sides of the upper end of the machine body, and a belt conveyor for conveying power is laid in the middle of the inner wall of the slide rails.

[0009] Preferably, friction lines are provided on the outer wall surface of the belt conveyor, and the belt conveyor is connected to the servo motor through a connecting belt. A barrier net is laid in the middle of the upper end of the machine body.

Through continuous heat exchange of the heat exchange aluminum plate and the heat exchange fins for the upper part of the machine body, it is ensured that the upper space of the entire machine body is in a suitable constant temperature environment, providing a sufficient and stable curing environment for the polyurethane glue of the glue filling dialyzer shell in the machine body, improving the qualified rate of polyurethane glue curing of the dialyzer, reducing the possibility of bubbles appearing during the curing of the polyurethane glue of the dialyzer, and bringing good economic benefits to the enterprise. The constant temperature box and the heat exchange aluminum plate form an air flow constant temperature circulation system through the through holes and pipes. This kind of constant temperature equipment has low cost and continuous constant temperature, meeting the requirements of green production.

[0025] Embodiment 2

[0026] Please refer to Figures 1-5, the present utility model provides a technical solution: a device for thermostatic speed control curing after injecting polyurethane glue into a dialyzer. On both sides of the upper end of the machine body 1, slide rails 12 are bolted. In the middle of the inner wall of the slide rails 12, a belt conveyor 13 for conveying power is laid. On the outer wall surface of the belt conveyor 13, friction lines are provided, and the belt conveyor 13 is connected to a servo motor through a connecting belt. In the middle of the upper end of the machine body 1, a barrier net 14 is laid. A fixing fixture 4 is slidably connected to the inner wall of the slide rail 12, and the middle part of the fixing fixture 4 is distributed in a hollow shape. The friction slider 43 is slidably connected to the slide rail 12, and the size of the friction slider 43 matches the size of the slide rail 12. The slide rail 12 and the belt conveyor 13 serve as conveying components to meet the flow requirements of the fixing fixture 4. At the same time, the speed of the belt conveyor 13 is regulated by the servo motor to ensure that the polyurethane glue is cured to a Shore hardness of 80 and then flows out of the machine body 1, providing good curing time for the curing of the polyurethane glue and facilitating the use of the user. At the same time, the slide rail 12 and the belt conveyor 13 adopt a linear conveying form to convey the glue-filled dialyzer housing 6, meeting the first-in-first-out effect of the glue-filled dialyzer housing 6 and providing guarantee for the batch production of the glue-filled dialyzer housing 6. The glue-filled dialyzer housing 6 is mounted on the upper end of the fixing fixture 4, and both ends of the glue-filled dialyzer housing 6 are aligned with the positioning holes 42. The machine body 1, the constant temperature deionized water tank 2, and the barrier net 14 form a lower space constant temperature environment. At the same time, the middle part of the fixing fixture 4 is distributed in a hollow shape and matches the lower space constant temperature environment to ensure that the lower environment of the glue-filled dialyzer housing 6 is also in a constant temperature environment, ensuring that the upper and lower environments of the entire glue-filled dialyzer housing 6 are in a constant temperature state, further meeting the curing requirements of the polyurethane glue.

[0027] Working principle: For the device for thermostatic speed control curing after injecting polyurethane glue into this type of dialyzer, first, the dialyzer housing 6 filled with glue is horizontally placed along the positioning holes 42 of the fixing jig 4. At this time, the user slides the friction sliders 43 on both sides of the fixing jig 4 into the slide rails 12, and the friction sliders 43 are in frictional contact with the belt conveyor 13. Meanwhile, the servo motor is started, and through flexible transmission, the belt conveyor 13 is driven to rotate, transferring the dialyzer housing 6 filled with glue on the fixing jig 4 into the machine body 1. At the same time, the constant temperature box 3, through the through hole 31 and the pipeline, forms an air flow constant temperature circulation system with the heat exchange aluminum plate 5. The polyurethane glue reacts and generates heat energy, and the heat exchange aluminum plate 5 and the heat exchange fin 51 perform heat exchange treatment. When the temperature of the heat exchange aluminum plate 5 and the heat exchange fin 51 is relatively high after heat exchange, the hot air is flowed to the radiator through the pipeline by the fan 52, and then the cooled air is returned to the heat exchange aluminum plate 5 for continuous constant temperature circulation. Meanwhile, the machine body 1, the constant temperature deionized water pool 2, and the barrier net 14 form a constant temperature environment in the lower space. The deionized water is conveyed to the ion water conveying pipeline 21 by pump pressure and then flows into the constant temperature deionized water pool 2. The ion water in the constant temperature deionized water pool 2 performs heat exchange treatment on the heat energy in the lower space. Finally, the polyurethane glue is cured to a Shore hardness of 80 and then flows out of the machine body 1, providing a good curing time for the curing of the polyurethane glue.
