Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a negative pressure dust collection device for textile machines. Background Technology

[0002] In the textile industry, the continuous operation of textile machines generates a large amount of lint. This lint not only adheres to the textile equipment, affecting its normal operation and lifespan, but also disperses throughout the workshop, causing serious air pollution and harming workers' health. Therefore, efficient ventilation and dust removal equipment is crucial for the production environment of textile workshops.

[0003] Currently, negative pressure fans for textile machinery are widely used for ventilation in textile workshops. They generate negative pressure to extract air containing lint from the workshop, thereby improving the air quality. However, existing negative pressure fans have obvious defects in actual use: on the one hand, most fans are only equipped with simple filters, which are not effective at filtering fine lint; on the other hand, the exhaust port design of the fans is not targeted and does not take into account the control of lint emissions. This results in a large amount of unfiltered lint being dispersed outdoors with the exhaust airflow when the negative pressure fan is running.

[0004] Therefore, a negative pressure dust collection device for textile machines is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a negative pressure dust collection device for textile machines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure dust collection device for textile machines, comprising a fan cover, an exhaust port on the surface of the fan cover, a preliminary filter screen on the inner wall of the exhaust port opening, a circumferentially distributed exhaust port on the other side of the fan cover, a filter screen on the inner wall of the exhaust port, a motor at the center of the side of the fan cover away from the exhaust port, a fan shaft fixedly connected to the output end of the motor and extending into the exhaust cavity, fan blades fixedly connected to the outer surface of the fan shaft, a collar fixedly connected to the outer surface of the fan shaft, a cleaning block fixedly connected to the outer surface of the collar, a groove on the side of the cleaning block facing the filter screen, a cleaning sponge inserted into the inner wall of the groove, and the cleaning sponge fitting snugly against the filter screen.

[0007] Preferably, the collar has a cleaning fluid tank inside, and the cleaning fluid tank is filled with cleaning fluid. Both one end of the cleaning fluid tank and the inner wall of the cleaning block have water seepage holes. The collar and the cleaning block are normally in the state of the cleaning block on top, so that the cleaning fluid in the cleaning fluid tank can be kept in a hanging state when the fan shaft is not rotating.

[0008] Preferably, the top of the cleaning block has an installation opening, and a roller is inserted into the inner wall of the installation opening. A rotating shaft is fixedly connected to the surface of the roller, and the rotating shaft is rotatably connected to the inner wall of the installation opening through a bearing. The top of the roller fits against the inner wall of the exhaust port, so that when the collar rotates with the fan shaft, the top of the cleaning block is prevented from wearing against the inner wall of the exhaust port, while coordinating the stability of both ends.

[0009] Preferably, a limiting frame is inserted into the inner wall of the air outlet, the filter screen is fixed to the inner wall of the limiting frame, the limiting frame is fan-shaped, a sealing strip is fixedly connected to the outer wall of the limiting frame, and a sealing groove is opened on the inner wall of the air outlet to engage with the sealing strip, so as to strengthen the sealing connection between the filter screen and the air outlet and prevent fine lint from escaping.

[0010] Preferably, a baffle is fixedly connected to one side of the limiting frame, and the surface of the baffle covers the opening of the air outlet, further enhancing the sealing effect between the air outlet and the installation location of the limiting frame. At the same time, the limiting frame can be removed from the inner wall of the air outlet by snapping on the baffle.

[0011] Preferably, a water-filled sealing plug is inserted into the surface of the collar, which facilitates the direct injection of cleaning fluid from the water-filled sealing plug. One of the limiting frames can be removed from the air outlet corresponding to the water-filled sealing plug, and then the cleaning fluid can be injected. At the same time, the water-filled sealing plug has a rebound sealing effect, and the cleaning fluid can be injected through a needle hole, which facilitates the automatic closure of the water-filled sealing plug.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Firstly, when this device is installed and used, the exhaust vent can initially block textile lint. As the air is discharged from the outlet, finer textile lint will pass through the filter screen for secondary blocking. At the same time, the rotation of the fan shaft causes the collar to rotate, carrying a cleaning sponge to wipe the surface of the filter screen, directly and simultaneously cleaning the filtered screen. In addition, the collar contains cleaning fluid, which can be swung into the inner wall of the groove through the drainage holes by the rotation of the fan shaft, saturating the cleaning sponge. This makes the cleaning sponge moist, which not only makes the filter screen better at absorbing textile lint, but also makes it easy to wipe. The wiped filter screen can always keep its surface moist, forming a third blocking barrier, thereby improving the practicality of existing negative pressure dust collection equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 An embodiment of this utility model is provided: a negative pressure dust collection device for textile machines, including a fan cover 1, an exhaust port 2 is provided on the surface of the fan cover 1, a preliminary filter screen is provided on the inner wall of the exhaust port 2, a circumferentially distributed exhaust port 3 is provided on the other side of the fan cover 1, a filter screen 4 is provided on the inner wall of the exhaust port 3, a motor 5 is provided at the center of the side of the fan cover 1 away from the exhaust port 2, a fan shaft 6 is fixedly connected to the output end of the motor 5 and passes through the cavity of the exhaust port 2, a fan blade 7 is fixedly connected to the outer surface of the fan shaft 6, a collar 8 is fixedly connected to the outer surface of the fan shaft 6, a cleaning block 9 is fixedly connected to the outer surface of the collar 8, a groove 10 is provided on the side of the cleaning block 9 facing the filter screen 4, a cleaning sponge 11 is inserted into the inner wall of the groove 10 and the cleaning sponge 11 is in contact with the filter screen 4.

[0023] Specifically, the collar 8 has a cleaning fluid tank 15 inside, which contains cleaning fluid. One end of the cleaning fluid tank 15 and the inner wall of the cleaning block 9 both have water seepage holes 16. The collar 8 and the cleaning block 9 are normally in the state of the cleaning block 9 being on top, so that the cleaning fluid in the cleaning fluid tank 15 can be kept hanging when the fan shaft 6 is not rotating.

[0024] Specifically, the top of the cleaning block 9 has an installation port 12, and a roller 13 is inserted into the inner wall of the installation port 12. A rotating shaft 14 is fixedly connected to the surface of the roller 13. The rotating shaft 14 is rotatably connected to the inner wall of the installation port 12 through a bearing. The top of the roller 13 fits against the inner wall of the exhaust port 2, so that when the collar 8 rotates with the fan shaft 6, the top of the cleaning block 9 is prevented from wearing against the inner wall of the exhaust port 2, while coordinating the stability of both ends.

[0025] Specifically, a limiting frame 18 is inserted into the inner wall of the air outlet 3, and the filter screen 4 is fixed to the inner wall of the limiting frame 18. The limiting frame 18 is fan-shaped, and a sealing strip 20 is fixedly connected to the outer wall of the limiting frame 18. A sealing groove 19 is opened on the inner wall of the air outlet 3 to engage with the sealing strip 20, which can strengthen the sealing connection between the filter screen 4 and the installation point of the air outlet 3 and prevent fine lint from escaping.

[0026] Specifically, a baffle 21 is fixedly connected to one side of the limiting frame 18. The surface of the baffle 21 covers the opening of the air outlet 3, further enhancing the sealing effect between the air outlet 3 and the installation location of the limiting frame 18. At the same time, the limiting frame 18 can be removed from the inner wall of the air outlet 3 by pulling the baffle 21.

[0027] Specifically, a water-filled sealing plug 17 is inserted into the surface of the collar 8, which facilitates the direct injection of cleaning fluid from the water-filled sealing plug 17. One of the limiting frames 18 can be removed from the air outlet 3 corresponding to the water-filled sealing plug 17, and then the cleaning fluid can be injected. At the same time, the water-filled sealing plug 17 has a rebound sealing effect, and the cleaning fluid can be injected through a needle hole, which facilitates the automatic closure of the water-filled sealing plug 17.

[0028] The operating steps are as follows: When in use, turn on motor 5. Motor 5 drives fan shaft 6 to rotate, which in turn drives fan blades 7 to rotate, creating negative pressure inside the fan shroud 1. Air containing lint enters the fan shroud 1 through the exhaust port 2. The initial filter screen initially blocks larger pieces of textile lint. The air continues to flow, passing through the circumferentially distributed exhaust ports 3. Finer textile lint is then further blocked by the filter screen 4 within the limiting frame 18 on the inner wall of the exhaust port 3. As fan shaft 6 rotates, it drives collar 8 to rotate, causing cleaning blocks 9 on collar 8 to rotate accordingly. The rollers 13 on top of cleaning blocks 9 roll on the inner wall of the exhaust port 2, preventing wear between the cleaning blocks 9 and the inner wall of the exhaust port 2, and ensuring stability at both ends. The cleaning sponge 11 on the cleaning block 9 is attached to the surface of the filter screen 4 to wipe it and remove the lint. At the same time, the centrifugal force generated by the rotation of the collar 8 causes the cleaning liquid in the cleaning liquid tank 15 to be thrown into the groove 10 through the seepage hole 16, which wets the cleaning sponge 11 and keeps it moist. This not only helps to better absorb lint, but also makes wiping easier. The surface of the filter screen 4 remains moist after wiping, forming a third barrier. In addition, after the equipment has been used for a period of time, the limiting frame 18 can be removed from the inner wall of the air outlet 3 by pulling the baffle 21 to perform deep cleaning or replacement of the filter screen 4. If cleaning liquid needs to be added, it can be added again through the water filling sealing plug 17.
