Description

Technical Field

[0001] The utility model relates to a spinning duct, in particular to a circular spinning duct for spandex production. Background Art

[0002] A spinning duct is an important component on a spinning machine, mainly used to provide a space for the formation of nascent fibers. In the production of spandex filaments, the spandex filament solution is extruded from the spinneret orifice and enters the spinning duct. Through the action of the hot air flow in the duct, harmful solvents in the solution stream quickly volatilize, the viscosity of the solution stream reaches a certain critical value to achieve solidification, forming spandex filaments. The volatilized harmful solvents are carried away by the hot air flow, and the spandex filaments gradually remove the harmful solvents.

[0003] A spinning duct disclosed in a patent application with the reference publication number CN213232579U includes: a duct body, a duct inlet and a duct outlet provided at both ends of the duct body, and further includes: an air inlet chamber provided on the top side of the duct body; a return air chamber provided on the top side of the duct body and symmetrically arranged with respect to the vertical center line of the duct body; a circulation pipeline with one end communicating with the air inlet chamber and the other end communicating with the return air chamber; a regulating plate provided at the bottom side of the air inlet chamber and arranged at a predetermined angle α with the duct body; a return air outlet provided at the bottom side of the regulating plate and communicating with the air inlet chamber through the circulation pipeline. This spinning duct of the utility model maximally reduces the content of harmful solvents in spinning, improves the physical indexes and subsequent processes of spinning, extends the storage time, and meets the environmental protection requirements.

[0004] As shown in the above prior art, a filter screen is provided in the air inlet chamber of the duct in the prior art to ensure the air quality of the air supply. Timely cleaning of the filter screen can effectively reduce the pressure difference before and after and solve the problem of uneven wind speed distribution. In the prior art, most filter screens are fixedly installed in the air inlet chamber, resulting in inconvenient cleaning of the filter screen and mostly requiring manual cleaning, which consumes manpower.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] The present utility model provides two technical solutions:

[0034] A duct body 1, with an air inlet chamber 2 installed on one side of the duct body 1. The air inlet chamber 2 is divided into a first pipe 3 and a second pipe 4. The first pipe 3 is fixedly connected to the duct body 1, and the second pipe 4 is fixed to one side of the duct body 1 through a bracket 5;

[0035] A filtering component is installed between the first pipeline 3 and the second pipeline 4 and is used to filter the hot air entering the main body 1 of the passageway.

[0036] The filtering component includes:

[0037] Two sliding sleeves 6 are respectively slidably connected to the outer walls of the first pipeline 3 and the second pipeline 4. A second sealing ring 18 is fixed to the inner wall of the sliding sleeve 6, and the second sealing ring 18 is in close fit with and slidably connected to the outer wall of the air inlet chamber 2.

[0038] Two filter meshes 7 are rotatably connected to the outer wall of the main body 1 of the passageway through a rotating shaft 9. The two filter meshes 7 are symmetrically fixed to the outer wall of the rotating shaft 9, and one of the filter meshes 7 is located between the first pipeline 3 and the second pipeline 4.

[0039] A first motor 8 is fixed to the outer wall of the main body 1 of the passageway, and the output end of the first motor 8 is fixed to the rotating shaft 9.

[0040] A descaling component is fixed to the outer wall of the main body 1 of the passageway and is used to scrape off the dirt on the filter mesh 7.

[0041] A sealing component is installed on the outer wall of the first pipeline 3 and is used to seal and connect the first pipeline 3, the filter mesh 7 and the second pipeline 4.

[0042] Three limiting blocks 10 are evenly and fixedly arranged on the outer walls of the first pipeline 3 and the second pipeline 4 at equal intervals. A sliding rod 11 is slidably connected to the inner wall of the limiting block 10, and the three sliding rods 11 on the same side are fixed to one side of the sliding sleeve 6.

[0043] The sealing component includes a slider 12 fixed to one side of the sliding sleeve 6. A bidirectional screw 13 is rotatably connected to the outer wall of the first pipeline 3, and the other end of the bidirectional screw 13 is rotatably connected to the outer wall of the second pipeline 4. The two sliders 12 are symmetrically threadedly connected to the outer wall of the bidirectional screw 13. A second motor 14 is fixed to the outer wall of the first pipeline 3, and the output end of the second motor 14 is fixed to the bidirectional screw 13.

[0044] A first sealing ring 15 is fixed to the opposite sides of the two sliding sleeves 6.

[0045] Through the setting of the filter mesh 7, the first motor 8 and the sealing component, when hot air is introduced into the spinning passageway, the hot air can be filtered by the filter mesh 7 through the air inlet chamber 2 to ensure good air quality, and during the interval of production shutdown, the filter mesh 7 can be quickly switched and cleaned electrically without manual operation, reducing labor consumption and ensuring cleaning efficiency.

[0046] Figure 2 The second embodiment is shown. The main difference from the first embodiment is that the descaling component includes a support rod 16 fixed directly below the first motor 8, and scraping plates 17 are symmetrically fixed above the support rod 16.

[0047] By providing a descaling component, during the process of switching and using the filter screen 7, both sides of the filter screen 7 can be cleaned simultaneously, ensuring the cleanliness of the filter screen 7. The cleaning work is simple and fast.

[0048] Working principle:

[0049] The duct body 1 adopts the duct body, air return opening, circulation pipeline, solvent recovery tank, etc. in CN213232579U, which is prior art and will not be elaborated here.

[0050] When using this spinning duct to produce spandex filaments, hot air needs to be introduced into the air inlet chamber 2 so that the hot air enters the duct body 1. To ensure the air supply quality, the filter screen 7 for filtering hot air in time needs to be cleaned after being used for a period of time.

[0051] During the interval when the production of spandex filaments stops, drive the second motor 14 to rotate the bidirectional screw 13, driving the slider 12 to move in a direction away from each other, so that the sliding sleeve 6 drives the sliding rod 11 to move within the limit block 10, and the sliding sleeves 6 move away from each other. Subsequently, the first motor 8 drives the rotating shaft 9 to rotate, turning the filter screen 7 originally located between the two sliding sleeves 6 downward, so that the dirty filter screen 7 passes between the scraping plates 17, and the dirt on both sides of the dirty filter screen 7 is scraped off by the scraping plates 17. At the same time, another filter screen 7 rotates to between the two sliding sleeves 6. The second motor 14 is started again, making the two sliding sleeves 6 move closer to each other until both first sealing rings 15 are in close contact with the filter screen 7 to complete the sealing of the air inlet chamber 2, and then hot air can be introduced into the air inlet chamber 2 to continue the spandex production work.
