DEVICE FOR DOSED FEED OF DISPERSED MATERIAL AND GLASS FILAMENTS IN GAS FLOW |
| 摘要 |
FIELD: glass decoration. SUBSTANCE: device has bunker with reserve of material and ejector in form of two coaxial tubes. Small tube of ejector is provided with thread on external surface and secured for rotation about its axis. Device ensures preset uniform feed of material from bunker to gas flow. Rate of feed may be controlled by changing the rotational speed of small tube. If glass filaments are used small tube cuts them prior to feed into sections, length of which depends on thread pitch. For this purpose provision is made for special profile of thread turns. EFFECT: reliable and uniform feed. 2 dwg
