However, the current method for feeding sodium carbonate powder commonly used in the industry has significant problems, and a more efficient and environmentally friendly feeding and conveying device is urgently needed to improve it.

[0003] Traditional sodium carbonate feeding typically involves unpacking ton bags from a discharge port. This method is not only labor-intensive but also presents a significant risk of dust emission. The sodium carbonate powder easily flies during unpacking and conveying, polluting the environment and posing a serious health risk to operators. This dust emission complicates cleanup and maintenance and poses a potential threat to the stable operation of production equipment.

[0004] At present, the PTA industry generally uses the method of unpacking ton bags from the discharge port when adding sodium carbonate powder. This is labor-intensive and causes sodium carbonate dust to float, causing environmental pollution and harm to human health. There is an urgent need for a closed feeding method to solve the dust dispersion problem. Utility Model Content

[0035] Working principle:

[0036] The powder is first placed in the funnel 2. The filter plate 25 inside the funnel 2 can effectively remove impurities in the powder, ensuring that the powder entering the system is pure. The lower end of the funnel 2 is connected to the drive motor 27 through the rotating blade 26. The start of the drive motor 27 drives the rotating blade 26 to rotate, promoting the uniform fall of the powder and effectively preventing the accumulation of powder in the funnel 2. When the powder in the funnel 2 reaches the preset amount, the vacuum device 8 of the vacuum feeder 7 starts to work, generating negative pressure, and extracting the powder from the funnel 2 through the first pipe 13 and transporting it to the inside of the vacuum feeder 7. After the powder enters the vacuum feeder 7, it passes through the internal fixed filter 9, which can purify the air entering the system, prevent dust from damaging the equipment, and ensure the purity of the powder. The vacuum feeder 7 accurately controls the powder delivery rate through the rotary valve 12 connected to its lower end, ensuring that the powder is continuously and stably supplied to the sodium carbonate dissolution tank 10. During powder conveying, a dust shield 17 fixed to the side of the bracket 1 and a symmetrical dust shield 3, both flexibly connected, form a dust isolation system, effectively preventing powder from dispersing during handling. The dust shield, formed by the first stretch curtain 6 at the upper end of the bracket 1 and the multi-stage stretch rod 19, slide column 21, and second stretch curtain 24 at the lower end, can be adjusted to accommodate different packaging bag sizes, further enhancing dust isolation, protecting operator health, and reducing environmental pollution. A Roots blower 15, fixed to one side of the vacuum loader 7 and connected to the vacuum loader 7 via a second pipe 14, provides powerful airflow for powder conveying. The squat design of the Roots blower 15 not only facilitates installation and maintenance but also reduces the impact of noise and vibration on the surrounding environment. After being compressed by the Roots blower 15, the powder is delivered through the discharge port 16 into the sodium carbonate dissolution tank 10 or other designated location. A discharge door 11, flexibly connected to the lower end of the vacuum loader 7, facilitates maintenance and cleaning during equipment downtime. The fixing bolts 28 fixedly connected to the funnel 2 ensure a firm connection between the various components of the equipment, thereby improving the stability and safety of the equipment operation.
