[0002] Microporous spinnerets are widely used in various fields, such as chemical industry, biomedicine, petroleum and environmental protection. These microporous spinnerets are usually used to control the injection, dispersion or mixing of gas or liquid to meet the precise flow and uniform injection requirements in different application scenarios.

[0003] In the prior art, microporous spinnerets are usually designed with a fixed aperture. When a higher flow rate is required, the microporous spinneret with a fixed aperture cannot provide sufficient fluid output. In this case, workers are required to replace the microporous spinneret with a different aperture.

[0004] However, when workers replace microporous spinnerets with different apertures, the microporous spinnerets are generally installed between the flange and the spinneret jacket. At this time, workers are required to use auxiliary tools to disassemble and replace the microporous spinnerets, which makes it inconvenient for workers to use and increases downtime, thereby affecting production efficiency.

DETAILED DESCRIPTION

[0024] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1-Figure 9 The utility model provides a technical solution: a combined microporous spinneret device with adjustable aperture, comprising a fixed tube 3, a spinneret 2 is arranged on the left side of the fixed tube 3, an adjusting ring 4 is arranged on the right side of the fixed tube 3, a connecting rod 8 is installed on the right side of the spinneret 2, and the other end of the connecting rod 8 is fixed on the left side of the adjusting ring 4, and an auxiliary tube 5 is installed on the right side of the adjusting ring 4.

[0027] First, rotate the adjusting ring 4 to a 90° angle. At this time, the fixed frame 1 blocks the larger wire outlet holes on the spinneret 2. As the left part of the adjusting ring 4 rotates with the fixed tube 3, the right part of the adjusting ring 4 rotates with the auxiliary tube 5, thereby driving the connecting rod 8 to rotate. At the same time, the spinneret 2 is arranged on the right side of the fixed frame 1, thereby driving the spinneret 2 to rotate 90°, so that the fixed frame 1 blocks the smaller wire outlet holes on the spinneret 2.

[0028] Embodiment 2

[0029] On the basis of embodiment 1, in order to facilitate the clamping of the adjustment ring, a plurality of slide grooves 15 are opened inside the adjustment ring 4, the inner wall of the slide groove 15 is slidably connected to a limit plate 17, the sides close to the upper and lower limit plates 17 are fixedly connected with a clamping block 12, and the inner wall of the slide groove 15 is installed with a spring 16.

[0030] While rotating and adjusting, the spring 16 will drive the limit plate 17 to move, and drive the block 12 to move toward the middle of the adjusting ring 4. When the adjusting ring 4 rotates 90°, the elastic force of the spring 16 will push the block 12 into the inner wall of the slot 11, thereby completing the aperture adjustment, and also locking the adjusting ring 4 to prevent it from rotating.

[0031] Embodiment 3

[0032] On the basis of the second embodiment, in order to facilitate the cleaning of the spinneret, a fixed frame 1 is sleeved on the outer side of the spinneret 2, the front and rear sides of the fixed tube 3 are fixedly connected with fixed blocks 6, the front and rear sides of the fixed frame 1 are fixedly connected with sliders 7, and the sliders 7 are inserted into the fixed blocks 6, and the right part of the fixed block 6 is rotatably connected with bolts a9.

[0033] The worker screws the bolt a9, and because the slider 7 slides inside the fixed block 6 and the slider 7 is threadedly connected to the bolt a9, the slider 7 moves leftward, thereby driving the fixed frame 1 to separate from the fixed tube 3, so that the worker can clean the spinneret 2 more easily.

[0034] Embodiment 4

[0035] On the basis of Example 3, in order to facilitate the disassembly of the spinneret, a connecting shaft 13 is fixedly connected to the right side of the spinneret 2, and the connecting shaft 13 is inserted into the left part of the connecting rod 8. Two bolts b14 are provided on the left part of the connecting rod 8, and the proximal ends of the two bolts b14 are threadedly connected to the right part of the connecting shaft 13.

[0036] The worker first disassembles the fixed tube 3, the adjusting ring 4 and the auxiliary tube 5 on the right side as a whole, then unscrews the bolt b14 and pulls the spinneret 2 to the left. At this time, the connecting shaft 13 will be separated from the connecting rod 8, making it convenient for the worker to disassemble the spinneret 2.

[0037] In actual use, the worker first rotates the adjustment ring 4 to a rotation angle of 90°. At this time, the fixed frame 1 blocks the larger-diameter wire hole on the spinneret 2. As the left part of the adjustment ring 4 rotates with the fixed tube 3, and the right part of the adjustment ring 4 rotates with the auxiliary tube 5, the connecting rod 8 is driven to rotate. At the same time, the spinneret 2 is arranged on the right side of the fixed frame 1, which drives the spinneret 2 to rotate 90°, so that the fixed frame 1 blocks the smaller-diameter wire hole on the spinneret 2. While rotating and adjusting, the spring 16 drives the limit plate 17 to move, and drives the block 12 to move toward the middle of the adjustment ring 4. When the adjustment ring 4 rotates 90°, the elastic force of the spring 16 will push the block 12 into the inner wall of the card slot 11, thereby completing the adjustment of the aperture, and can also lock the adjustment ring 4 to prevent it from rotating.

[0038] After long-term use, a small amount of waste will accumulate on the inner wall of the spinneret 2 hole. At this time, the worker screws the bolt a9, and because the slider 7 slides inside the fixed block 6, and the slider 7 is threadedly connected to the bolt a9, the slider 7 is driven to move to the left, and then the fixed frame 1 is driven to separate from the fixed tube 3, so that the worker can clean the spinneret 2 conveniently.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
