Slag discharging device for dust collector

The present invention relates to the preparation of titanium tetrachloride, slag discharge means disposed at the bottom of the precipitator dust collector (15), comprising a dust collector plate (10) and the blade slagging machine, dust collector plate (10) the dust collector is connected by bolts (15) a flange (12), with a seal (11) seal, dust collector plate (10) with a residue collection hopper (13); slagging machine during work, the motor (1 ) by reduction gearbox (2) to the driven bevel gear (5), (6), and then the drive shaft (8) to the power transmission residue scraping plate (9), scraping residue plate (9) about an axis (8) weeks rotation, the bottom plate precipitator dust will fall on the slag (10) fall into the slag hopper scraper (13), the timing slagging valve opening (14), the dust collection slag discharged slag pool. The present invention is good airtight performance, safety and reliability, avoids the problem of adhesion of slag dust collection equipment, can improve the operating rate of the equipment, stable furnace conditions conducive to environmental protection to achieve good results smooth discharge of slag dust collection.
