Description
(54) ПОРОШКОВЫЙ ПИТАТЕЛЬ(54) POWDER FEEDER
1one
Изобретение относитс к аппаратуре дл нанесени газотермических покрытий из порошковых материалов, в частности к пневматическим порошковым питател м, примен емым преимущественно в комплекте с распылительной газопламенной горелкой, снабженной инжектором дл транспортировани порошка.The invention relates to an apparatus for applying gas-thermal coatings made from powder materials, in particular to pneumatic powder feeders, used primarily in combination with a gas flame spray gun equipped with an injector for transporting powder.
Известен порошковый питатель, содержащий резервуар, трубчатый заборник с коническим раструбом на входе, на выходе которого установлен инжектор, смесительна камера с диффузором и сопло 1.A powder feeder is known that contains a reservoir, a tubular intake with a conical socket at the inlet, at the outlet of which an injector is installed, a mixing chamber with a diffuser and a nozzle 1.
Однако известное устройство не обеспечивает качество транспортировани и обладает высокой инерционностью.However, the known device does not provide the quality of transportation and has a high inertia.
Цель изобретени - повышение качества транспортировани порошка и снижение инерционности устройства.The purpose of the invention is to improve the quality of transportation of the powder and reduce the inertia of the device.
Поставленна цель достигаетс тем, что в порошковом питателе, преимущественно в установках дл нанесени газотермических покрытий, содержащем резервуар, трубчатый заборник с коническим раструбом на входе, на выходе которого установлен инжектор, смесительную камеру с диффузором и сопло, инжектор установлен от смесительной камеры на рассто нии 0,7-1,2 диаметра смесительной камеры, диаметр которой составл ет 0,2-0,3 внутреннего диаметра цилиндрической части заборни5 ка.The goal is achieved by the fact that in a powder feeder, mainly in installations for applying thermal coatings containing a reservoir, a tubular intake with a conical socket at the inlet, the outlet of which is equipped with an injector, a mixing chamber with a diffuser and a nozzle, the injector is installed from the mixing chamber at a distance of 0.7-1.2 diameters of the mixing chamber, the diameter of which is 0.2-0.3 of the inner diameter of the cylindrical part of the intake.
На чертеже изображен порошковый питатель , общий вид.The drawing shows a powder feeder, a general view.
Порошковый питатель состоит из резер10 вуара 1, трубчатого заборника 2 с коническим раструбом 3 и сопла 4, на выходе трубчатого заборника 2 установлены инжектор 5, смесительна камера 6 с диффузором 7.The powder feeder consists of a reservoir 10 of the veil 1, a tubular intake 2 with a conical socket 3 and a nozzle 4, an injector 5 is installed at the outlet of the tubular intake 2, a mixing chamber 6 with a diffuser 7.
Порошковый питатель работает следую5 щим образом.The powder feeder works as follows.
За счет инжекции в заборнике 2 создаетс разрежение. В конический раструб 3 заборника 2 поступает порошок, который из конца цилиндрической части заборника 20 транспортируетс в смесительную камеру 6 и, мину диффузор 7 с соплом 4, поступает в гибкий трубопровод. Через трубопровод S порошок транспортируетс в порошковый канал распылительной горелки, в которомDue to the injection in the intake 2, a vacuum is created. Powder enters the conical socket 3 of the inlet 2, which is transported from the end of the cylindrical part of the intake 20 to the mixing chamber 6 and, by the way, the diffuser 7 with the nozzle 4 enters the flexible pipeline. Through pipe S, the powder is transported to the powder channel of the spray burner, in which
