Description

Technical Field

[0001] The utility model relates to the technical field of flakers, in particular to a rotary drum structure of a caustic soda flake flaker. Background Art

[0002] The caustic soda flake machine mainly includes a drum, a driving motor, a transmission wheel, a transmission belt, a spray structure, a scraper structure, a cooling structure, a recovery plate and a frame. The alkali solution is sprayed on the drum by the spray structure, and then cooled by the cooling structure on the drum. The cooled caustic soda flakes are scraped off by the scraper structure on the other side of the drum. The main problem at present is that the cooling structure on the drum is either set outside the drum or inside the drum. Although the cooling effect is good, there is still room for improvement. At the same time, the distribution of the cooling structure should be that the drum is cooled in a specific area above the spray structure. Otherwise, in the area where the drum is below the spray structure, after the blank is cooled, it is sprayed again by the spray structure as the drum rotates, which is easy to produce layered caustic soda flakes, which is not conducive to scraping by the scraper, and the caustic soda flakes are easy to break. For example, a Chinese patent (CN116371294B) discloses a rotary drum cooling crystallization flake machine, which belongs to the technical field of flake machines and includes a bracket and a rotary drum. The rotary drum is driven by a motor. A spray plate is provided on one side of the rotary drum. Shrapnel and a guide frame are fixedly connected to the spray plate. The slurry can be sprayed on the rotary drum to form a slurry layer. The rotary drum drives the slurry layer thereon to rotate. The slurry layer will be cooled by the coolant inside the cooling tube during the rotation, thereby forming flakes. The flakes will be scraped off when they encounter a scraper. The scraper is controlled by an airbag to exert a pressing force on the rotary drum, and the air inside the airbag will cool down the scraper when it is discharged through the air outlet, thereby promoting the detachment of the flakes and avoiding affecting the subsequent scraping work. The scraped flakes will fall into the receiving frame and can be taken out by opening the baffle door. The technical solution adopts an annular cooling tube arranged in the rotary drum, which can easily cause the area of ​​the rotary drum below the spray structure to form flakes, which are not easy to form flakes after being scraped by the scraper.

Moreover, since double internal and external cooling is performed only on the upper side of the drum between the cooling structure and the scraper structure, stratification of caustic soda flakes caused by cooling of the drum in other areas is avoided, thereby improving the flaking effect.

[0011] 1. The utility model arranges cooling devices inside and outside the upper side of the drum, and adopts a bow-shaped cooling pipe to clamp inside and outside of one end of the drum, thereby improving the cooling effect.
