A multistage dirt device of catching for surpassing high temperature vacuum sintering furnace

The utility model provides a multistage dirt device of catching for surpassing high temperature vacuum sintering furnace, including enclosed housing, intake pipe, fender gas board, the first round platform of a plurality of form pipe, a plurality of second round platform form pipe and third round platform form pipe, this application utilizes the intake pipe, keep off the gas board, first round platform form pipe, second round platform form pipe and third round platform form pipe have enclosed in enclosed housing and have turned the gas flow passageway to complications more one, meet with whengas circulates in this gas flow passageway stops the collision many times, dust in many times blockking collision in -process gas is isolated from gas, gas outgoing enclosed housing behind the final desorption dust, the dust of isolating gathers in enclosed housing, thereby realized purifying the dirt of catching from super high temperature vacuum sintering furnace combustion gas, make the dust volume that gets into in th
