Anti-blocking device for a rotary furnace and rotary furnace comprising it

Abstract

The utility model provides a kind of for rotary furnace's anti-blocking device and the rotary furnace including it, rotary furnace includes furnace body and gas outlet pipe, furnace body includes discharge section, anti-blocking device includes reverse gas outlet mechanism, reverse gas outlet mechanism is located in discharge section and close to the side of gas outlet pipe, reverse gas outlet mechanism includes the gas inlet and gas outlet of intercommunication, gas outlet is used to be connected with gas outlet pipe, the angle between the axis of the opening direction of gas inlet and the rotary axis of rotary furnace along the gas outlet direction of reverse gas outlet mechanism is 0~90 °.The utility model makes that dust material with gas flow is not easy to enter reverse gas outlet mechanism through gas inlet by anti-blocking device, and then also not easy to enter gas outlet pipe from reverse gas outlet mechanism, so that condensation phenomenon will not occur after gas outlet pipe meets cold, so that dust material humidity increases, leading to appear sticky block, avoid the problem of gas outlet pipe blockage, improve the stability and production efficiency of rotary furnace production.

Claims
