Description

Technical Field

[0001] The present invention relates to the technical field of ES fiber production technology, and in particular to an exhaust device for ES fiber production. Background Art

[0002] ES fiber is a composite fiber with excellent physical properties. During the production process of ES fiber, certain waste gases will be generated, and these waste gases contain dust and fibers sublimated by high temperature. Therefore, an exhaust device is required to discharge and treat the gases.

[0003] When the existing exhaust device is in use, it lacks the ability to recover the sublimated fibers. The fiber gas will be discharged together with the purified gas. These gases are somewhat toxic and will cause air pollution after being discharged. Moreover, there may be a certain amount of dangerous condensation remaining in the exhaust device, resulting in the exhaust purification ability of the exhaust device being affected. At the same time, the existing exhaust device lacks the ability to recover the heat in the waste gas, causing the heat to be wasted and consuming a large amount of energy, which is not conducive to the use of the device.

[0004] Therefore, we propose an exhaust device for ES fiber production to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art, and to propose an exhaust device for ES fiber production.

A corresponding upper fixed cylinder and a lower fixed cylinder are rotatably installed inside the fixed tank. The upper fixed cylinder and the lower fixed cylinder are connected by a fixed pipe. The gas collection plate and the upper fixed cylinder are connected by a guide pipe. A power structure is installed on the purification tower;

[0009] A treatment structure. The treatment structure includes moving grooves opened on the upper fixed cylinder and the lower fixed cylinder. A moving block is sleeved on the fixed pipe. A fixed spring is fixedly connected between the moving block and the inner wall of the moving groove. A fixed ring is slidably sleeved on the fixed pipe. A sealing pad is rotatably sleeved on the side wall of the fixed ring, and the sealing pad is in close contact with the corresponding upper fixed cylinder and lower fixed cylinder. A fixed cam is fixedly sleeved on the fixed pipe. The upper inner wall of the upper fixed cylinder is fixedly connected with an extrusion plate.

[0010] As another technical solution, a collection structure is installed on the lower fixed cylinder. The collection structure includes a collection box fixedly clamped at the bottom end of the purification tower. A fixed through groove is formed between the collection box and the lower fixed cylinder. The fixed pipe passes through the collection structure and extends to the inside of the collection box. A reciprocating lead screw is fixedly sleeved on the fixed pipe. A lead screw slider is mechanically engaged with the reciprocating lead screw. A telescopic bracket is fixedly connected to the lead screw slider. A fixed scraper is fixedly connected to the telescopic bracket. The fixed scraper is slidably connected to the inner wall of the collection box, and the fixed scraper is an elastic telescopic structure.

[0011] As another technical solution, the collection box is a hollow sandwich structure, and a filter layer is fixedly installed inside the collection box.

[0012] As another technical solution, a connecting cylinder is fixedly connected inside the upper fixed cylinder. A connecting plate is fixedly connected inside the connecting cylinder. A return spring is fixedly connected between the connecting plate and the fixed pipe. A spiral ring is fixedly connected to the inner wall of the connecting cylinder. An elastic telescopic rod is fixedly connected to the side wall of the fixed pipe. A pushing block is rotatably connected to the end face of the elastic telescopic rod, and the pushing block abuts against the spiral ring.

[0013] As another technical solution, the power structure includes a motor fixedly connected to the purification tower. The output end of the motor is fixedly connected to a rotating rod. The rotating rod penetrates through the inner walls of the purification tower and the fixed tank and extends to the inside of the fixed tank. A plurality of stirring rods are fixedly connected to the side wall of the rotating rod. A fixed toothed ring is fixedly sleeved on the rotating rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In the present invention, the gas will enter the fixed pipe, and the gas in the fixed pipe is cooled by the cooling water in the fixed tank. The cooling water absorbs the heat, achieving the effect of recovering heat energy. At the same time, the fixed pipe rotates to centrifuge the gas inside it, making the gas approach the inner wall of the fixed pipe, enhancing the heat exchange between the gas and the cooling water, and further improving the effect of heat energy recovery;

[0019] 2. In the present invention, during the cooling process, the fibrous gas in the gas also sublimates into fibrous solids. The fibrous solids are pushed by the subsequent gas and finally enter the collection box to facilitate the recovery of the fibers. Moreover, during the rotation of the fixed tube, the fixed tube vibrates in the horizontal and vertical planes, thereby preventing the fibers from adhering to the inner wall of the fixed tube and enabling them to enter the collection box. At the same time, the rotation of the fixed tube also increases the contact between the fixed tube and the cooling water, further improving the cooling effect, avoiding the situation where some fibers do not sublimate, and enhancing the recovery effect.

[0020] 3. In the present invention, by using the rotation of the fixed tube, the fixed scraper moves up and down. The up and down movement of the fixed scraper can scrape the inner wall of the collection box, scraping off the fibers that enter the collection box and causing the fibers to gather at the lower inner wall of the collection box. This is beneficial for the collection of the fibers while not affecting the exhaust. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0030] Refer to Figures 1 - 8 , an exhaust device for ES fiber production, comprising:

[0031] A purification tower 1 and a gas collecting plate 2. A fixed tank 3 is fixedly installed inside the purification tower 1. The fixed tank 3 is filled with cooling water. A water inlet pipe and a drain pipe are fixedly connected to the side wall of the fixed tank 3. A corresponding upper fixed cylinder 5 and a lower fixed cylinder 7 are rotatably installed inside the fixed tank 3. The upper fixed cylinder 5 and the lower fixed cylinder 7 are connected by a fixed pipe 9. The gas collecting plate 2 and the upper fixed cylinder 5 are connected by an air duct 4. A power structure is installed on the purification tower 1;

[0032] The gas enters the upper fixed cylinder 5 of the fixed tank 3 through the gas collecting plate 2 and the air duct 4, then enters the lower fixed cylinder 7 through the fixed pipe 9, and finally is discharged. When the gas enters the fixed pipe 9, the cooling water quickly cools the gas, so that the sublimated fiber gas in the gas is cooled and condensed into a solid. At the same time, under the action of the power device, the upper fixed cylinder 5 and the fixed pipe 9 rotate, and the gas in the fixed pipe 9 is centrifuged, so that the gas can be close to the inner wall of the fixed pipe 9, thereby improving its cooling ability;

[0033] A treatment structure 6. The treatment structure 6 includes moving grooves 61 opened on the upper fixed cylinder 5 and the lower fixed cylinder 7. A moving block 62 is sleeved on the fixed pipe 9. A fixed spring 63 is fixedly connected between the moving block 62 and the inner wall of the moving groove 61. A fixed ring 64 is slidably sleeved on the fixed pipe 9. A sealing gasket 65 is rotatably sleeved on the side wall of the fixed ring 64, and the sealing gasket 65 is in close contact with the corresponding upper fixed cylinder 5 and lower fixed cylinder 7. The sealing gasket 65 plays a sealing role to prevent the cooling water from entering the upper fixed cylinder 5 and the lower fixed cylinder 7. A fixed cam 66 is fixedly sleeved on the fixed pipe 9. The upper inner wall of the upper fixed cylinder 5 is fixedly connected with an extrusion plate 67. The side wall of the extrusion plate 67 is provided with a rounded corner to facilitate the mutual extrusion of the extrusion plate 67 and the fixed cam 66. Multiple extrusion plates 67 are symmetrically arranged with the center of the end face of the fixed pipe 9 as the center of the circle;

[0034] When the fixed tube 9 rotates, the fixed cam 66 fixedly sleeved on the fixed tube 9 will rotate accordingly. During the rotation of the fixed cam 66, it will squeeze the extrusion plate 67, thereby causing the fixed cam 66 and the fixed tube 9 to move, making the fixed spring 63 contract. After the elastic force of the fixed spring 63 causes the fixed cam 66 to separate from the extrusion plate 67, the fixed tube 9 vibrates in the horizontal direction, thus shaking off the sublimated fibers, preventing them from adhering to the inner wall of the fixed tube 9 and facilitating the collection of the fibers. At the same time, the back-and-forth vibration of the fixed tube 9 also increases its contact with the cooling water, improving the cooling effect;

[0035] A collection structure 8 is installed on the lower fixed cylinder 7. The collection structure 8 includes a collection box 10 fixedly clamped at the bottom end of the purification tower 1. The clamped collection box 10 can be conveniently removed. There is a fixed through groove between the collection box 10 and the lower fixed cylinder 7. The fixed tube 9 passes through the collection structure 8 and extends to the inside of the collection box 10. A reciprocating lead screw 81 is fixedly sleeved on the fixed tube 9. A lead screw slider 82 is mechanically engaged with the reciprocating lead screw 81. A telescopic bracket 83 is fixedly connected to the lead screw slider 82. The telescopic bracket 83 ensures that the vibration of the fixed tube 9 will not be affected. A fixed scraper 84 is fixedly connected to the telescopic bracket 83. The fixed scraper 84 is slidably connected to the inner wall of the collection box 10, and the fixed scraper 84 is an elastic telescopic structure; The collection box 10 is a hollow sandwich structure, and a filter layer is fixedly installed inside the collection box 10. Air can be discharged from the filter layer, while the fibers remain in the collection box 10;

[0036] When the fixed tube 9 rotates, the reciprocating lead screw 81 fixedly sleeved on its outer side rotates accordingly, causing the lead screw slider 82 mechanically engaged with the reciprocating lead screw 81 to move up and down reciprocally. The movement of the lead screw slider 82 drives the telescopic bracket 83 to move, causing the fixed scraper 84 to move up and down accordingly. The fixed scraper 84 scrapes the inner wall of the collection box 10, scraping off the fibers on the inner wall of the collection box 10 and making the fibers gather at the lower inner wall of the collection box 10 for easy collection of the fibers;

[0037] A connecting cylinder 68 is fixedly connected inside the upper fixed cylinder 5. The connecting cylinder 68 is sleeved on the outside of the fixed tube 9 and the two are concentric. A connecting plate 69 is fixedly connected inside the connecting cylinder 68. A return spring 610 is fixedly connected between the connecting plate 69 and the fixed tube 9. A spiral ring 611 is fixedly connected to the inner wall of the connecting cylinder 68. The spiral ring 611 is a three-dimensional spiral structure, and its structural shape is similar to a spring. At the same time, the spiral ring 611 is not a complete circle and there is a notch on the spiral ring 611, so that when the pushing block 613 moves to the notch, it can be reset under the action of the return spring 610. An elastic telescopic rod 612 is fixedly connected to the side wall of the fixed tube 9. The end face of the elastic telescopic rod 612 is rotatably connected to a pushing block 613, and the pushing block 613 abuts against the spiral ring 611;

[0038] As the fixed pipe 9 rotates, the elastic telescopic rod 612 and the pushing block 613 rotate together. When the pushing block 613 rotates, it moves along the trajectory of the spiral ring 611, causing the pushing block 613 and the fixed pipe 9 to move downward in the vertical plane, stretching the return spring 610. When the pushing block 613 moves to the end of the spiral ring 611, the elastic force of the return spring 610 causes the fixed pipe 9 to reset, causing the fixed pipe 9 to vibrate in the vertical plane and enhancing the vibration of the fixed pipe 9;

[0039] The power structure includes a motor 11 fixedly connected to the purification tower 1. The output end of the motor 11 is fixedly connected with a rotating rod 12. The rotating rod 12 penetrates through the inner walls of the purification tower 1 and the fixed tank 3 and extends into the interior of the fixed tank 3. A plurality of stirring rods 13 are fixedly connected to the side wall of the rotating rod 12. A fixed gear ring 14 is fixedly sleeved on the rotating rod 12, and a fixed gear 15 meshing with the fixed gear ring 14 is fixedly sleeved on the upper fixed cylinder 5;

[0040] After the motor 11 is started, its output end drives the rotating rod 12 to rotate. When the rotating rod 12 rotates, it drives the stirring rods 13 to rotate accordingly, agitating the cooling water, increasing the amount of cooling water in contact with the fixed pipe 9 for easy cooling. At the same time, when the rotating rod 12 rotates, the fixed gear ring 14 sleeved on its outer side rotates accordingly, causing the fixed gear 15 meshing with the fixed gear ring 14 to rotate, driving the upper fixed cylinder 5 to rotate together;

[0041] The side wall of the purification tower 1 is rotatably connected with a fixed cover plate. The side wall of the purification tower 1 is fixedly connected with a ladder. Opening the fixed cover plate can repair the structure inside the purification tower 1, and at the same time, the fibers in the collection box 10 can be taken out. The ladder facilitates the repair personnel to climb;

[0042] The purification tower 1 is fixedly connected with an exhaust pipe communicating with the inside of the device. The side wall of the purification tower 1 is fixedly connected with an air outlet pipe. The exhaust pipe is installed at the top of the purification tower 1 and is connected to the exhaust fan air duct of the fiber production device. The air outlet pipe is installed at the bottom of the side wall of the purification tower 1;

[0043] A filtering device is installed inside the purification tower 1, and the filtering device is connected to the gas collecting plate 2. The filtering device is an existing device, so its operating principle will not be described in detail. The filtering device is used to filter out dust and other impurities in the gas, and the air enters the gas collecting plate 2.

[0044] During the use of the present invention, the discharged gas enters the upper fixed cylinder 5 of the fixed tank 3 through the filtering device, the gas collecting plate 2 and the air guide pipe 4. The filtering device filters out dust and other impurities in the gas, then enters the lower fixed cylinder 7 through the fixed pipe 9, and finally is discharged;

[0045] When the gas enters the fixed tube 9, the cooling water quickly cools the gas, causing the sublimated fiber gas in the gas to cool and condense into a solid. At the same time, the motor 11 is started. After the motor 11 is started, its output end drives the rotating rod 12 to rotate. When the rotating rod 12 rotates, it will drive the stirring rod 13 to rotate accordingly, agitating the cooling water, causing the cooling water to move as well, increasing the amount of cooling water in contact with the fixed tube 9 for easy cooling. At the same time, when the rotating rod 12 rotates, the fixed gear ring 14 sleeved on its outer side rotates accordingly, causing the fixed gear 15 meshing with the fixed gear ring 14 to rotate, driving the upper fixed cylinder 5 to rotate together. The upper fixed cylinder 5 and the fixed tube 9 rotate, centrifuging the gas in the fixed tube 9, enabling the gas to approach the inner wall of the fixed tube 9, thereby enhancing its cooling capacity;

[0046] When the fixed tube 9 rotates, the fixed cam 66 fixedly sleeved on the fixed tube 9 will rotate accordingly. During the rotation of the fixed cam 66, it will squeeze the extrusion plate 67, causing the fixed cam 66 and the fixed tube 9 to move, making the fixed spring 63 contract. After the elastic force of the fixed spring 63 causes the fixed cam 66 to separate from the extrusion plate 67, the fixed tube 9 vibrates horizontally, thereby shaking off the sublimated fibers, preventing them from adhering to the inner wall of the fixed tube 9 and facilitating the collection of the fibers. At the same time, the back-and-forth vibration of the fixed tube 9 also increases its contact with the cooling water, improving the cooling effect;

[0047] Moreover, the rotation of the fixed tube 9 causes the elastic telescopic rod 612 and the pushing block 613 to rotate together. When the pushing block 613 rotates, it will move along the track of the spiral ring 611, causing the pushing block 613 and the fixed tube 9 to move downward in the vertical plane, stretching the return spring 610. When the pushing block 613 moves to the end of the spiral ring 611, the elastic force of the return spring 610 causes the fixed tube 9 to reset, causing the fixed tube 9 to vibrate in the vertical plane, further enhancing the overall vibration of the fixed tube 9;

[0048] In addition, as the fixed tube 9 rotates, the reciprocating lead screw 81 fixedly sleeved on its outer side rotates accordingly, causing the lead screw slider 82 mechanically engaged with the reciprocating lead screw 81 to move up and down reciprocally. The movement of the lead screw slider 82 drives the telescopic support 83 to move, causing the fixed scraper 84 to move up and down accordingly. The fixed scraper 84 scrapes the inner wall of the collection box 10, scraping off the fibers on the inner wall of the collection box 10, causing the fibers to accumulate at the lower inner wall of the collection box 10 for easy collection of the fibers.
