Side clearance is 0.6-0.8mm.
It is using the advantageous effect after above-mentioned technical proposal：Crystallizer discharges to catching in a kind of melamine industrial equipment
Gas control dredge valve on storage pipeline solves melamine plant crystallizer by the technical program using gas control dredging mode
Discharge pipe frequent jams problem adds inflated with nitrogen, nitrogen to enter crystallization through fumarole air seal intracavitary by gas source pipe
The one-way flow control pipeline of gas medium of the device discharge pipe control containing solid particle, high temperature, high pressure blocks, while nitrogen
It being ejected into through fumarole on the rotating disc of break dredger, rotating disc generates rotation under guide vane effect, rotates adjusting handle,
Rotating disc moves forward, and the fixation particle at the easily blocking of crystallizer discharge pipe can be carried out break by the break tool on rotating disc
Processing blocks to reach effective control pipeline, and the production cycle greatly shortens, and really realizes the stabilization of equipment, efficient, long period
Operation.
