Изобретение относитс к пневмотранспорту сыпучих материалов и может быть использовано , например, дл транспортировани металлического песка.The invention relates to the pneumatic transport of bulk materials and can be used, for example, for transporting metallic sand.
Известно заборное устройство вакуумной пневмотранспортной установки, содержащее корпус, смонтированный в корпусе приемный насадок и закрепленный на наружной поверхности последнего патрубок дл подачи атмосферного воздуха 1.A vacuum intake device for pneumatic conveying installation is known, comprising a housing, a receiving nozzle mounted in the housing and mounted on the outer surface of the latter nozzle for supplying atmospheric air 1.
Недостаток известного устройства заключаетс в том, что оно не обеспечивает эффективного захвата транспортируемого материала вследствие плохой эрозии последнего под действием потока воздуха.A disadvantage of the known device is that it does not ensure the effective capture of the transported material due to the poor erosion of the latter under the action of air flow.
Цель изобретени - повышение эффективности работы устройства.The purpose of the invention is to increase the efficiency of the device.
Поставленна цель достигаетс тем, что приемный патрубок установлен в корпусе под углом к горизонтальной плоскости, равным углу естественного откоса материала, а выходной конец указанного патрубка примыкает к входному торцу насадка и выполнен со скошенным торцом, угол между которым и торцом насадка равен 20-30°, причем в стенке выходного конца этого патрубка,The goal is achieved by the fact that the receiving nozzle is installed in the housing at an angle to the horizontal plane equal to the angle of repose of the material, and the output end of the specified nozzle is adjacent to the input end of the nozzle and is made with a beveled end, the angle between which and the nozzle is 20-30 ° , moreover, in the wall of the output end of this nozzle,
смежной с выходным торцом насадка, выполнен продольный паз.adjacent to the output end of the nozzle, made a longitudinal groove.
На фиг. 1 изображено заборное устройство вакуумной пневмотранспортной установки , общий вид; на фиг. 2 - вид А на фиг. 1.FIG. 1 shows the intake of a vacuum pneumatic conveying installation, general view; in fig. 2 is a view A of FIG. one.
Устройство содержит корпус 1, в котором под углом к горизонту, равном углу естественного откоса материала, установлен приемный насадок 2, соединенный с транспортным трубопроводом. На наружной поверхности насадка 2 смонтирован патрубок 3 The device includes a housing 1, in which an receiving nozzle 2 connected to a transport pipeline is installed at an angle to the horizon equal to the angle of repose of the material. On the outer surface of the nozzle 2 is mounted pipe 3
10 дл подачи атмосферного воздуха, выходной конец которого примыкает к входному торцу а насадка 2. Торец б выходного конца 4 патрубка 3 выполнен скошенным, причем угол между ним и торцом анасадка 2 равен 5 20-30°. Торец а( дл увеличени входного сечени насадка) также имеет скос в. В стенке патрубка 3, смежной с торцом а, выполнен продольный паз в.10 for supplying atmospheric air, the output end of which is adjacent to the inlet end of the nozzle 2. The end end 6 of the outlet end 4 of the nozzle 3 is made bevelled, and the angle between it and the end of the anchor 2 is 5-20-30 °. The butt end (for increasing the inlet cross section of the nozzle) also has a bevel. In the wall of the pipe 3, adjacent to the end a, a longitudinal groove is made in.
Устройство работает следующим образом .The device works as follows.
2020
Материал засыпают в корпус 1..При этом под рабочим торцом устройства за счет его скоса образуетс воздушное пространствоворонка , поверхность которой составит сThe material is poured into the housing 1.. At the same time, under the working end of the device, due to its bevel, an air spacer is formed, the surface of which is
