Description

Известны устройства дл  инжекционного напылени  порошкообразных материалов (смол, пластмасс и т. п.) на предварительно нагретую поверхность изделий (например, статоров или роторов электрических машин).Devices for injection spraying powdered materials (resins, plastics, etc.) onto pre-heated products (for example, stators or rotors of electrical machines) are known.

Основными узлами известных устройств  вл ютс  питаюш,ий бачок вихревого типа и инжекторы - распылители, соединенные с бачком при помощи шлангов. К распылител м - инжекторам подаетс  также сухой очиш;енный сжатый воздух, который, проход  через инжектор , увлекает частицы порошка напыл емого материала, наход щегос  во взвешенном состо нии в питающем бачке вихревого типа.The main components of the known devices are a power supply unit, a vortex type tank and injectors — sprayers connected to the tank by means of hoses. Dry-cleaned compressed air is also supplied to the spray guns - the injectors, which, passing through the injector, entrains particles of the powder of the sprayed material, which is suspended in the feed vortex type tank.

Недостатком известных зстройств  вл етс  неравномерность получаемых с их помош;ью покрытий, обусловленна  изменением концентраций воздушно-порошковой смеси, подаваемой к инжекторам.A disadvantage of the known devices is the unevenness of the coatings obtained with their help, due to the change in the concentrations of the air-powder mixture supplied to the injectors.

Изменение концентрации воздушно-порошковой смеси  вл етс  следствием убыли порошка в бач.ке в процессе напылени .The change in the concentration of the air-powder mixture is a consequence of the loss of powder in the tank during the spraying process.

Кроме того, недостатком известных устройств с бачком вихревого типа  вл етс  прерывность их действи , св занна  с необходимостью загрузки порошка н бачок.In addition, a disadvantage of the known devices with a vortex-type tank is their discontinuity associated with the need to load the powder on the tank.

Указанные недостатки устран ютс  в предлагаемом устройстве благодар  использованию питател  (например, шнекового), непрерывно подающего в вихревой бачок напыл емый порошок в количестве, восполн ющем расход порошка при напылении.These drawbacks are eliminated in the proposed device due to the use of a feeder (for example, a screw screw), continuously feeding the sprayed powder into the vortex tank in an amount that compensates for the consumption of powder during spraying.

Благодар  этому достигаетс  посто нство концентрации воздушно-порошково : смеси,Due to this, a constant concentration of air-powder is achieved: mixtures,

Предмет изобретени Subject invention

Устройство дл  инжекциониого напылени  порошкообразных материалов, содержащее бачок вихревого типа и соединенные с ним инжекторы , отличающеес  тем, что, с целью повышени  равномерности наносимого покрыти  при одновременном достижении непрерывности процесса напылен-и , вихревой бачок снабжен питателем непрерывного действи , напридмер шнековым, обеспечивающим непрерывную подачу в Вихревой бачок напыл емого материала в количестве, восполн ющем расход порошка при цапылении.A device for injection spraying of powdery materials, containing a vortex type tank and injectors connected to it, characterized in that, in order to improve the uniformity of the applied coating while simultaneously achieving the continuity of the sprayed process, in the Vortex tank of the sprayed material in an amount that compensates for the consumption of powder during gumming.
