I have been working hard in tunneling all year round. Usually, I wear the dust mask issued by the company when going into the well. Even if I change the filter element every shift, there is still some coal dust in the sputum I cough up after a shift. I have been trying on the mask invented by Master Xu for almost a month now, and the phlegm I cough up every day is clear Xu Mingjin, a worker from Comprehensive Excavation Zone 1, happily told me.
Xu Jihai, the inventor of liquid filtration dust and gas masks, is an ordinary miner at Xin'an Coal Industry Company. After nearly 20 years of working hard in tunneling, he is still an "inventor" with four national invention patents. The liquid filtration dust and gas mask and portable dust mask invented by him have obtained national patent certificates and registered trademarks.
In order to turn his invention into reality, Xu Jihai cooperated with professional mechanical processing and manufacturing factories such as Xuzhou and Rizhao. After 19 model updates and spending 150000 yuan, he produced a batch of experimental products using non-toxic materials such as silicone and plastic. After more than 100 frontline workers in the mine tried them on, the response was good.
In addition, his invented disinfectant chopstick box and rubber boot cleaning machine have also obtained national utility model invention patent certificates.
