Second scraper device is to rotate 180 ° around axial offset in the relative position of telescopic shaft；First scraper device and the second scraper device
It include multiple blades, blade bearing, multiple supporting elements and connector；Heap is welded with anticorrosion antiwear layer at the blade of the blade, mentions
The service life and scraper effect of high blade, and be uniformly attached on blade bearing for conical helical pattern；The blade bearing is semicircle
Annular and surface are equipped with corrosion resistant thickening layer, and thickening layer plays protection and firm effect to the connection of blade, improve to liquid
Resistance to corrosion, the blade bearing is fixedly connected with one end of multiple supporting elements；The other end of supporting element is solid with connector
It connects calmly and radially distributed outward, the supporting element is small, the big sector structure in extension position with connector connection end
And its surface is uniformly covered with circular through hole, shape, through-hole and the distribution form of supporting element reduce liquid and mention to its impact force
High working efficiency can also prevent the solid-liquid layer that separator well is stired and make muddy when scraper scraper when playing the role of being reliably connected；It is described
Connector is connect with telescopic shaft interference, guarantees the reliable operating of scraper device, effectively scraping material, and can be individually replaced scraper
Device reduces maintenance difficulty.
Preferably, the blade head of second scraper device is provided with hard cleaning brush, can further clean scraper not
With the material of drum inner wall contact portion, the service life of rotary drum is improved, improves working efficiency.
The utility model reached it is following the utility model has the advantages that
1, wear-resistant, corrosion-resistant, impact resistance, long service life.2, the setting of the first scraper device and the second scraper device
Saving material reduces maintenance cost and difficulty.3, the setting of circular through hole sky reduces impact of the liquid to it on supporting element
Corrosion, and the solid layer and liquid level of separated mistake are not upset.4, rotation axis retractable structure keeps it shrinkable when not working
Stoste is avoided to prolong the service life its corrosion in one end of rotary drum.
