Description

Technical Field

[0001] This utility model relates to the field of filter cleaning, and in particular to a filter self-cleaning system. Background Technology

[0002] In the textile industry, as people's requirements for the quality and performance of textiles continue to increase, the development of new yarns has become crucial. ATY, as a yarn with unique appearance and performance, has seen its production technology developed to meet the market's demand for diversified, high-quality textiles.

[0003] ATY's production is primarily based on air-textured yarn technology. This technology utilizes high-speed airflow to spray, intertwine, and shape filaments, giving the yarn a fluffy, soft appearance and characteristics similar to staple fiber yarn. The introduction of moisture plays a crucial role in this process. Moisture helps stabilize the airflow and regulate the yarn's temperature and humidity, thus affecting the yarn's texture and quality.

[0004] Moisture needs to be removed by a fan in a timely manner. ATY's production equipment is equipped with an exhaust pipe, and a filter screen is installed on the pipe between the exhaust pipe and the fan. Because the ATY yarn contains oil, the moisture at this time is somewhat dirty, and the filter screen will often become clogged, causing the fan to fail to remove the moisture in time, which affects product quality and reduces production efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a filter self-cleaning system.

[0006] The filter self-cleaning system provided in this application adopts the following technical solution:

[0007] A filter self-cleaning system includes a first exhaust unit and a second exhaust unit. Both the first and second exhaust units include a fan, a transfer box, and a dirt tank. The fan and the transfer box are connected and communicate with each other through a connecting pipe. The transfer box and the air outlet are connected and communicate with each other through a connecting pipe. The dirt tank is located below the transfer box and is connected and communicated with the transfer box through a connecting pipe. A filter is installed on the connecting pipe near the transfer box.

[0008] A flow meter and a nozzle are installed on the connecting pipe. The flow meter monitors the wind speed of the corresponding fan. The nozzle is located near the filter screen. The nozzle includes an integrally formed vertical pipe section and an inclined pipe section. One end of the vertical pipe section extends into the connecting pipe and the other end extends out of the connecting pipe. The outlet of the high-pressure water is connected to the outside of the vertical pipe section. The end of the inclined pipe section away from the vertical pipe section is inclined towards the filter screen.

[0009] An electric shut-off valve is installed on the second connecting pipe. A control panel is installed on ATY's production equipment. A start button is installed on the control panel. The start button controls the electric shut-off valve and fan of the first exhaust unit to open.

[0010] The control panel is equipped with a PLC control system, which is electrically connected to the start button, anemometer, electric shut-off valve, and high-pressure water drive source.

[0011] Preferably, the first connecting pipe has an installation slot with a central angle of 180°. An installation arc plate is fixedly connected to the outer peripheral wall of the filter screen. The width of the installation arc plate is greater than the width of the filter screen. After the filter screen is inserted into the installation slot, the outer peripheral wall of the filter screen fits against the inner peripheral wall of the first connecting pipe. The inner arc surface of the installation arc plate fits against the outer arc surface of the third connecting pipe. Fixing bolts are provided on both sides of the installation arc plate in the width direction. The fixing bolts pass through the installation arc plate and are threaded to the third connecting pipe.

[0012] Preferably, the dirt tank is provided with a drain outlet, and a door is rotatably provided at the drain outlet, and the door is fixed to the dirt tank by connecting bolts.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. After pressing the start button, the electric shut-off valve and fan of the first exhaust unit open simultaneously. When the anemometer detects that the airflow rate of the fan in the first exhaust unit is lower than the set value, the anemometer sends a signal to the PLC control system. The PLC control system controls the electric shut-off valve and fan of the second exhaust unit to open and close the electric shut-off valve and fan of the first exhaust unit. At this time, the second exhaust unit works normally and the first exhaust unit stops running. Then, the PLC control system controls the high-pressure water drive source of the first exhaust system to turn on. The high-pressure water blows the dirt on the filter screen into the transfer box through the nozzle. Under the effect of the high-pressure water spraying in the inclined direction, the dirt accumulated in the transfer box falls into the dirt box from the connecting pipe three.

[0017] When the anemometer detects that the air velocity and flow rate of the fan in the second exhaust unit are lower than the set value, the anemometer sends a signal to the PLC control system. The PLC control system controls the electric shut-off valve and fan of the first exhaust unit to open and close the electric shut-off valve and fan of the second exhaust unit. At this time, the first exhaust unit works normally and the second exhaust unit stops running.

[0018] The system maintains a good filtration effect at all times, and can automatically and promptly remove the dirt accumulated on the filter screen, keeping the filter screen unobstructed and preventing the filtration performance from being affected by dirt accumulation. This ensures a stable and reliable filtration effect and improves product quality.

[0019] The filter screen ensures the system's continuous and stable operation during the cleaning process, reduces equipment downtime caused by filter screen cleaning, and improves overall production efficiency. Attached Figure Description
