Description
Technical field
The utility model belongs to solid caustic soda production equipment technical field, more particularly to a kind of piece alkali for solid caustic soda production system
Machine rotary drum.
Background technology
Flake caustic unit rotary drum is the core equipment in solid caustic soda production system, and operation principle is that 32 °C of cooling waters pass through water inlet end
Fixation hollow axis enters the spray equipment inside rotary drum, is shunted by spray equipment, uniformly spray table in rotary drum cylindrical shell
On face, 420 °C of lye are uniformly sprayed by upstream equipment on rotary drum cylindrical shell outer surface, and cooling water passes through rotary drum cylindrical shell
Body cools down lye, and lye is set on rotary drum cylindrical shell outer surface, and 50 °C of solid caustic soda are scraped by the scraper on auxiliary device, is formed
Piece alkali to the downstream of 20mm × 20mm × (0.8~1.5) mm is packed, and is formed finished product and is stored, is stored after cool water shower
Inside rotary drum cylindrical shell, by the way of pressure and inhaling rainbow, flowed out from water outlet fixation hollow axis, by downstream processes,
It recycles.The flake caustic unit rotary drum of the prior art includes cylindrical shell, left flat cover, right flat cover, fixation hollow axis, rotation hollow shaft
And spray equipment.But there are the following problems for flake caustic unit rotary drum in the prior art：
（1）Since the cylindrical shell of rotary drum is rolled by polylith carbon steel sheet welding, i.e., the cylindrical shell of rotary drum is by polylith
Tablet is rolled into cylinder welding, then by multiple cylinder butt welding, thus on the cylindrical shell of rotary drum formed multiple tracks longitudinal seam and
Multiple tracks girth joint, lye spray on the outer surface of the cylindrical shell of rotary drum, and the outer surface of cylindrical shell is easily corroded, and cylinder
The outer surface of shell is smooth surface, keeps finished product sheet alkali shapes and sizes all irregular, need to can be only achieved into through subsequent processing
Product requirement；
