Description

Technical Field

[0001] This utility model belongs to the field of textile filter cleaning technology, and in particular relates to an automatic cleaning device for Lyocell textile filter screens. Background Technology

[0002] Currently, the filter screens used in the lyocell spinning industry are replaced frequently. Due to material adhering to the screen and the small pores, the removed screens are difficult to clean thoroughly. Microscopic examination of the cleaned screens reveals that many pores are not completely cleaned and are not fully permeable. This problem remains difficult to solve. Typical lyocell spinning companies use the following method to clean and inspect the cleaning effect: The removed filter screens are placed on a fixed support, and a manual high-pressure water gun is used to spray high-pressure water onto the screens for cleaning. The manual cleaning of Lyocell textile filters is labor-intensive and creates a harsh working environment due to the splashing of high-pressure water, especially in the cold winter. During the cleaning process, workers' clothes become soaked from the water spray, which has a serious impact on their health and does not comply with employee safety and hygiene regulations. Even after workers believe the cleaning is complete, the filters are sent to the inspection room for testing. It is found that many filter holes are not thoroughly cleaned, requiring them to be returned to the cleaning room for further cleaning. This repeated process not only affects spinning production but also increases the workload for filter cleaners and negatively impacts their health. Therefore, in the current technology, manual cleaning of Lyocell textile filters is inconvenient and inefficient. Summary of the Invention

[0003] This invention addresses the technical problems of inconvenient and inefficient cleaning of lyocell textile filters in existing technologies by providing an automatic cleaning device for lyocell textile filters. The device includes a cleaning tank with an open top. Inside the tank is a horizontally positioned support platform, which is fixed to the inner wall of the tank. A vertically positioned rotating shaft is rotatably mounted on the support platform. The upper end of the rotating shaft extends upwards above the support platform, and a horizontally positioned placement platform for the filter screen is fixed to the top of the rotating shaft. The lower end of the rotating shaft extends downwards below the support platform. A drive mechanism is located on the right side of the cleaning tank, and is connected to the lower end of the rotating shaft. The drive mechanism includes a motor bracket fixed to the right side of the cleaning tank, with a vertically positioned drive motor mounted on the bracket. A driven pulley is fixed to the lower end of the rotating shaft, and a drive pulley is fixed to the power output shaft of the drive motor. A transmission belt connects the drive pulley and the driven pulley. The drive motor is connected to a power supply and control system via a cable. Starting the drive motor causes the rotating shaft to rotate via the transmission belt, thereby rotating the placement platform at the top of the rotating shaft. The rear of the cleaning tank is equipped with a front-to-back displacement mechanism, which includes a horizontally arranged slide rail with a U-shaped groove. A slider matching the groove is slidably connected in the groove. The mechanism also includes a lead screw arranged parallel to the slide rail, with both ends of the lead screw rotatably mounted on the ends of the slide rail. A lead screw motor is fixed to the outer end of the slide rail. The power output shaft of the lead screw motor is connected to the lead screw drive, and the slider is threadedly connected to the lead screw. The lead screw motor is connected to the power supply and control system via a cable. When the lead screw motor is started, it pushes the slider along the slide rail through the lead screw, thus adjusting the distance between the slider and the cleaning tank. Above the front-to-back displacement mechanism is a vertically installed lifting mechanism. The lower end of the lifting mechanism is fixed to the front-to-back displacement mechanism. The lifting mechanism includes a vertically installed lower support tube, the bottom end of which is fixed to the top end of the slider. A vertically installed upper support tube is sleeved on the upper end of the lower support tube, and the top end of the upper support tube is fixed to the bottom end of the support plate. An electric actuator is installed inside the lower end of the lower support tube. The bottom end of the electric actuator is hinged to the bottom end of the lower support tube, and the top end of the electric actuator is hinged to the bottom end of the upper support tube. The electric actuator is connected to the power supply and control system through a cable. When the electric actuator is activated, it pushes the upper support tube to move freely in the vertical direction along the inner wall of the lower support tube, thereby adjusting the distance between the water spray head and the placement platform. The top of the lifting mechanism is fixed with a horizontally set support plate. Above the support plate is a Z-shaped water pipe. Several supporting columns are fixed between the water pipe and the support plate. Several spray heads are fixed to the right end of the water pipe. It also includes a water pump. A hose connects the water pump to the water pipe. A drainage mechanism is set at the left end of the cleaning tank. The water pump is connected to the power supply and control system through a cable. The water pump delivers cleaning water to the spray heads and uses the spray heads to perform high-pressure rinsing of the filter screen.

[0004] Preferably, the drainage mechanism includes a water storage tank located below the left end of the support platform, a drain pipe at the bottom of the water storage tank, and a cleaning box extending from the lower end of the drain pipe.

[0005] Preferably, the water storage tank is equipped with a filter screen that serves as a filter.

[0006] Preferably, the top surface of the support platform is an inclined surface with the left side lower than the right side, which facilitates the flow of sewage and wastewater after rinsing the filter screen into the water storage tank.

[0007] The above scheme has the following advantages: The drive mechanism rotates the placement platform via a rotating shaft, causing the filter screen on the platform to rotate with it. This allows for comprehensive cleaning of the filter screen under the action of the water spray head, increasing the cleaning area and improving cleaning efficiency. The lifting mechanism adjusts the distance between the water spray head and the filter screen on the placement platform, thus adjusting the cleaning area of ​​the filter screen sprayed with rinsing water and improving cleaning efficiency. The front and rear displacement mechanism adjusts the distance between the water spray head and the center of the placement platform as needed, enabling cleaning of filter screens of different sizes and improving adaptability. In conjunction with the lifting mechanism, the water spray head can be moved out of the water tank for easy loading and unloading of the filter screen on the placement platform.

[0014] Usage process: In use, this invention first activates the electric push rod 73 within the lifting mechanism 7. The electric push rod 73 pushes the upper support tube 72 upward along the inner wall of the lower support tube 71 until the spray head 41 moves upward out of the cleaning tank 1. Then, the lead screw motor 55 on the front-to-back displacement mechanism 5 is activated. The lead screw motor 55 pushes the slider 53 away from the cleaning tank 1 via the lead screw 54 until the spray head 41 is completely removed from the cleaning tank 1. Then, the filter screen to be cleaned is placed on the placement platform 2. Finally, the front-to-back displacement mechanism 5 and the lifting mechanism 7 again move the spray head 41 upward.
