Design of the forming device with a vertical blow head for the production of synthetic fibers intended for filter process in the mining industry

摘要

It is generally known that the underground water is also extracted into the mining process during the mining of rocks, solids ordifferent liquid substances. These mining processes need to be drained and, given the increased demand for organic processes, water has tobe separated from undesirable substances. One of the undesirable substances in the mining process is the oil from the hydraulics miningmachines that can contaminate this water. Various technologies and devices are used for filtration, for example, separators. Theseseparators contain filters that can also be made from synthetic fibrous materials. The synthetic fibrous materials for the filters aremanufactured by different technologies. The article presents the technology of producing synthetic fiber material by vertical blowing methodfrom thermoplastic raw materials. Namely, the characteristics of the fiber forming device (blow head with an annular converging nozzle) aredefined and designed. As a result of the blow head investigation, the values of air rarefaction and air flow in the central hole of the annularnozzle were determined from the process parameters. Also, the result of the blow head study is the determination of the designcharacteristics, the influence assessment of various design and operational factors on its work, allowing the elementary fibers to be drawnout in a single technological cycle to form a fibrous material for the filters.
