Description
Изобретение относите к трубопроводному транспорту сыпучих материалов, а именно к трубопроводу дл напорного пневмотранспорта .The invention relates to the pipeline transport of bulk materials, namely to the pipeline for pressure pneumatic conveying.
Цель изобретени - повышение срока службы.The purpose of the invention is to increase the service life.
На фиг. 1 изображена установка пневмотранспорта с трубопроводом; на фиг. 2 - узел 1 на фиг. 1; на фиг. 3 - вид А на фиг. 1; на фиг. 4 - вид Б на фиг. 1.FIG. 1 shows the installation of pneumatic transport with a pipeline; in fig. 2 — node 1 in FIG. one; in fig. 3 is a view A of FIG. one; in fig. 4 is a view B in FIG. one.
Трубопровод содержит трубу, выполнен- ную с чередующимис между собой секци ми 1 большего проходного сечени и сек- 1,и ми 2 меньшего проходного сечени .The pipeline contains a pipe made with alternating between each other sections 1 of a larger passage section and section-1, and 2 of a smaller passage section.
Секци 1 имеет длину L(10-15) d где d - диаметр секции 2.Section 1 has a length of L (10-15) d where d is the diameter of section 2.
Площадь проходного сечени секции 1 равна 1,2-3,0 1 , где FC - площадь поперечного сечени секции 2.The flow area of section 1 is 1.2-3.0 1, where FC is the cross-sectional area of section 2.
Транспортируемый материал камерным питателем 3 подаетс в трубопровод. РазгоThe transported material is fed into the pipeline by a chamber feeder 3. Razgo
н сь далее сжатым воздухом, материал на пр молинейном участке приобретает ускорение , после чего он поступает в секцию 1 со скоростью свыше 20 м/с, потом расшир етс и тер ет скорость. На выходе из секции 1 снова разгон етс , однако транспортируемый материал разгон етс медленнее , чем воздух, поэтому скорость материала на выходе из секции 1 не только меньше, чем на входе в нее, но и значительно меньше средней скорости, и составл ет 8,5-12,5 м/с, а концентраци его выше, чем на входе в камеру (что обеспечивает посто нство потока материала по длине трубопровода).Next, with compressed air, the material on the straight line acquires acceleration, after which it enters section 1 at a speed of over 20 m / s, then expands and loses speed. At the exit of section 1, it accelerates again, however, the transported material accelerates slower than air, therefore the speed of the material at the exit of section 1 is not only lower than at the entrance to it, but also significantly less than the average speed, and is 8.5 -12.5 m / s, and its concentration is higher than at the entrance to the chamber (which ensures the constancy of the material flow along the length of the pipeline).
Выполнение трубы с секци ми большего и меньшего сечени позвол ет значительно снизить скорость прохождени материала через колено 4 перед приемным бункером 5, что повышает срок службы трубопровода.Making a pipe with sections of larger and smaller cross sections allows to significantly reduce the speed of material passing through the bend 4 in front of the receiving bin 5, which increases the service life of the pipeline.
