Description

Technical Field

[0001] This utility model belongs to the field of hollow fiber nanofiltration membrane filter element assembly technology, and particularly relates to a membrane tube and end cap assembly device for filter elements. Background Technology

[0002] Hollow fiber nanofiltration membrane cartridges are core filtration components for fluid purification. They typically consist of porous membrane tubes, end caps, and a support structure, and are made of materials including ceramic, PVDF, and stainless steel. Utilizing the precise pore size of the membrane tubes for sieving and adsorption, they intercept suspended solids, gaseous dust, or liquid impurities in water while allowing qualified fluids to pass through. They are widely used in water treatment, industrial production, pharmaceutical sterilization, and food purification, and are key equipment for achieving fluid separation and purification.

[0003] Existing hollow fiber nanofiltration membrane filter cartridges have some drawbacks during assembly, such as the need for manual alignment and assembly of the membrane tube and end cap, resulting in poor positioning accuracy and susceptibility to eccentricity and tilting, directly leading to sealing failure or filter cartridge installation compatibility issues. Therefore, we propose a membrane tube and end cap assembly device for filter cartridges. Utility Model Content

[0004] The purpose of this invention is to provide a membrane tube and end cap assembly device for filter cartridges, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a membrane tube and end cap assembly device for filter elements, including a base, and further comprising:

[0006] A sliding groove is formed inside the base, and two sliding strips are slidably installed inside the sliding groove. A power cavity is formed inside the base, and two sliding plates are slidably installed inside the power cavity. The two sliding plates are respectively located on both sides of the sliding groove.

[0007] A driving component, located within the base, is used to drive two sliding bars to slide.

[0008] The first motor is fixedly installed in the power cavity. The output shaft of the first motor is fixedly installed with a threaded rod. One end of the threaded rod passes through two sliding plates. The threaded rod is provided with two sections of threads with opposite directions. The threaded rod is threadedly connected to the two sliding plates. Rotation grooves are opened in both sliding plates. Several rectangular plates are slidably installed in both rotation grooves.

[0009] Two sets of power components are located in two sliding plates and are used to drive several rectangular plates to slide.

[0010] In this technical solution, the membrane tube is first placed between two sliding bars. Through the set driving component, the two sliding bars can be driven to slide and move closer to each other, and the two sliding bars can fix the membrane tube.

[0011] Then the head body is placed between several rectangular plates. Through the set power component, the rectangular plates can be driven to slide, and the rectangular plates can fix the position of the head body.

[0012] Finally, the staff applied glue to both ends of the membrane tube, then started the first motor and drove the threaded rod to rotate. Under the action of the thread, the threaded rod drove the two sliding plates to move closer to each other. The two sliding plates respectively drove the two end caps to contact the membrane tube. Finally, the two end caps and the membrane tube were assembled with glue. The operation is convenient and simple, and the assembly efficiency is improved.

[0015] In this technical solution, the membrane tube is placed between two sliding bars, then the second motor is started and drives the disc to rotate. The disc pulls the two connecting rods to rotate, and the two connecting rods pull the two sliding bars to slide and move closer to each other. The two sliding bars can fix the membrane tube.

[0016] In the above technical solution, the power component further includes:

[0017] The third motor is fixedly mounted on the sliding plate. The output shaft of the third motor passes through the sliding plate and extends into the rotating groove. A rotating disk is fixedly mounted on the output shaft of the third motor. Several guide grooves are opened on the rotating disk. Guide columns are slidably installed in each of the several guide grooves. The several guide columns are respectively fixedly connected to several rectangular plates.

[0018] In this technical solution, the end cap is placed between several rectangular plates. Then, the third motor is started and drives the rotating disk to rotate. The rotating disk can drive several guide columns to slide through the guide groove. The guide columns drive several rectangular plates to slide respectively. The rectangular plates drive several anti-slip rubber pads to fix the position of the end cap.

[0019] In the above technical solution, further, two second guide rods are fixedly installed in the power cavity, one end of each of the two second guide rods passes through two sliding plates, and the two sliding plates are slidably connected to the two second guide rods respectively.

A plurality of third guide rods are fixedly installed in each of the two rotating grooves, one end of each of the plurality of third guide rods passes through a plurality of rectangular plates, and the plurality of rectangular plates are slidably connected to the plurality of third guide rods respectively.

[0020] In this technical solution, by setting two second guide rods, a first guide rod, and several third guide rods, it is ensured that the two sliding plates, two sliding bars, and several rectangular plates can all slide stably.

[0021] In the above technical solution, furthermore, anti-slip rubber pads are fixedly installed on one side of each of the rectangular plates.

[0022] In this technical solution, the anti-slip rubber pad is set to compress and deform the end cap body, ensuring that the end cap body can be stably clamped and fixed.

[0023] In the above technical solution, further, several rectangular plates are distributed in a ring at equal intervals on the sliding plate.

[0024] In this technical solution, it is ensured that several rectangular plates can stably clamp and fix the head body.

[0025] In the above technical solution, the threaded rod is rotatably connected to the power cavity, the disc is rotatably connected to the sliding groove, the rotating disk is rotatably connected to the rotating groove, and the output shaft of the third motor is rotatably connected to the sliding plate and the rotating groove.

[0048] Finally, the staff applied glue to both ends of the membrane tube, then started the first motor 6 and drove the threaded rod 7 to rotate.

One end of each of the several third guide rods 20 passes through several rectangular plates 9, and the several rectangular plates 9 are slidably connected to the several third guide rods 20.

[0057] The system includes two second guide rods 19, a first guide rod 13, and several third guide rods 20, which ensure that the two sliding plates 5, the two sliding bars 3, and the several rectangular plates 9 can all slide stably. Example 3:

[0058] This embodiment provides a membrane tube and end cap assembly device for filter cartridges, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] In this embodiment, anti-slip rubber pads 18 are fixedly installed on one side of several rectangular plates 9.

[0060] Among them, the anti-slip rubber pad 18 is set to compress and deform the end cap body, ensuring that the end cap body can be stably clamped and fixed. Example 4:

[0061] This embodiment provides a membrane tube and end cap assembly device for filter cartridges, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0062] In this embodiment, several rectangular plates 9 are distributed in a ring at equal intervals on the sliding plate 5.

[0063] Among them, several rectangular plates 9 are used to ensure that the head body can be stably clamped and fixed. Example 5:

[0064] This embodiment provides a membrane tube and end cap assembly device for filter cartridges, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0065] In this embodiment, the threaded rod 7 is rotatably connected to the power chamber 4, the disc 11 is rotatably connected to the sliding groove 2, the rotating disc 15 is rotatably connected to the rotating groove 8, and the output shaft of the third motor 14 is rotatably connected to the sliding plate 5 and the rotating groove 8.

[0066] Specifically, it ensures that the threaded rod 7 can rotate stably in the power chamber 4, that the disc 11 can rotate stably in the sliding groove 2, that the rotating disc 15 can rotate stably in the rotating groove 8, and that the output shaft of the third motor 14 can rotate stably in the sliding plate 5 and the rotating groove 8.

[0067] Working principle: First, place the membrane tube between the two sliding bars 3. Then, start the second motor 10 and drive the disc 11 to rotate. The disc 11 pulls the two connecting rods 12 to rotate. The two connecting rods 12 pull the two sliding bars 3 to slide and move closer to each other. The two sliding bars 3 can fix the membrane tube.

[0068] Then the end cap is placed between several rectangular plates 9. Next, the third motor 14 is started and drives the rotating disk 15 to rotate. The rotating disk 15 can drive several guide posts 17 to slide through the guide groove 16. The several guide posts 17 drive several rectangular plates 9 to slide respectively. The several rectangular plates 9 drive several anti-slip rubber pads 18 to fix the position of the end cap.

[0069] Finally, the staff applied glue to both ends of the membrane tube, then started the first motor 6 and drove the threaded rod 7 to rotate. Under the action of the thread, the threaded rod 7 drove the two sliding plates 5 to move closer to each other. The two sliding plates 5 respectively drove the two end caps to contact the membrane tube. Finally, the two end caps and the membrane tube were assembled with glue. The operation is convenient and simple, and the assembly efficiency is improved.

[0070] In conventional understanding, membrane tube and end cap assembly equipment typically requires independent positioning and driving mechanisms, along with additional calibration components to ensure coaxiality, resulting in complex equipment structures and large space requirements. This embodiment, however, cleverly integrates the sliding bar 3 (membrane tube positioning) and the sliding plate 5 (end cap support) within the sliding groove 2 and power chamber 4 of the base 1. Utilizing a single power source—the first motor 6 driving the threaded rod 7—it simultaneously achieves the opposing movement of the sliding plate 5 (end cap advancement) and the synchronous positioning of the sliding bar 3 (membrane tube fixing), breaking the conventional design concept of "multiple power sources driving multiple mechanisms." Furthermore, the combination of the rotating groove 8 and the rectangular plate 9 eliminates the need for additional calibration components; automatic end cap alignment is achieved solely through the sliding clamping of the rectangular plate 9. This overturns the technical understanding that "high-precision assembly must rely on complex calibration structures," simplifying the equipment structure, reducing the number of parts, lowering the probability of equipment failure and maintenance costs, and providing a new design approach for the development of miniaturized, low-cost filter assembly equipment.

[0071] Furthermore, the combination of base 1, sliding groove 2, sliding bar 3, power chamber 4, sliding plate 5, first motor 6, threaded rod 7, rotating groove 8, rectangular plate 9, and power assembly forms a composite functional system of "bidirectional synchronous positioning - adaptive clamping," resulting in adaptability effects exceeding those of conventional assembly equipment. When faced with membrane tubes and end caps of different diameters, the sliding bar 3 in sliding groove 2 can flexibly adjust its spacing through the drive assembly to adapt to changes in the outer diameter of the membrane tube; simultaneously, the first motor 6 in power chamber 4 drives the threaded rod 7 to move the sliding plate 5, and in conjunction with the sliding of the rectangular plate 9 in rotating groove 8 under the action of the power assembly, it can automatically adjust the clamping range to adapt to end caps of different diameters. This dual-dimensional adaptive adjustment capability of "membrane tube-end cap" breaks through the limitation of "single specification adaptation" of traditional assembly equipment, allowing the assembly of filter elements of various sizes to be completed without changing the clamps, greatly improving the equipment's versatility and scenario adaptability, and eliminating the need for downtime debugging when switching specifications, further shortening production preparation time and indirectly improving overall assembly efficiency.

[0072] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
