Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and more specifically, to a disc dryer for drying bromochlorohydantoin. Background Technology

[0002] Bromochlorohydantoin is a novel chlorine- and bromine-containing disinfectant with specific properties. In aqueous solution, it reacts with water to generate a highly oxidizing active substance, which effectively disrupts the cell walls, active enzymes, or DNA of microorganisms, causing them to become inactive due to oxidative decomposition. It kills various pathogens, fungi, viruses, algae, and some parasites. It has the inherent advantages of high efficiency, stability, safety, and environmental friendliness, and is a widely used new broad-spectrum disinfectant.

[0003] Currently, the production of bromochlorohydantoin both domestically and internationally mainly uses 5,5-dimethylhydantoin, liquid alkali, bromine, and chlorine as raw materials. The process involves synthesis, centrifugation, drying into powder form, followed by granulation and tableting to produce tablets (blocks). Disc dryers are commonly used in the drying process of bromochlorohydantoin production.

[0004] A disc dryer is a drying device that primarily uses heat conduction. It includes a vertically arranged rotating shaft and a drying disc (heating disc) coaxial with the rotating shaft. A rake rod is connected to the rotating shaft, and multiple rake blades are installed on the rake rod. The rake rod rotates with the rotating shaft, causing the rake blades to agitate the material on the drying disc, allowing the material to be heated evenly and achieving drying.

[0005] In traditional disc dryers, the rake blades and rake rods are prone to deformation during use due to the adhesion of materials during drying. The deformation causes friction when they come into contact with the drying disc, resulting in equipment downtime for maintenance. In addition, the materials may contain magnetic substances, leading to poor product quality.

[0006] A search revealed Chinese patent application number CN202222861326.6, which discloses a disc dryer comprising an upper rake arm assembly, a lower rake arm assembly, and a demagnetizing device. The upper rake arm assembly includes an upper rake rod connected to a rotating shaft, and the lower rake arm assembly includes a lower rake rod connected to the rotating shaft. Multiple rake blades are hung on both the upper and lower rake rods. Both the upper and lower rake arm assemblies also include rake rod frames and rake rod hangers. The rake rod frames of the upper rake arm assembly are spaced apart above the upper rake rods, with one end connected to the rotating shaft and the other end connected to the upper rake rod via the rake rod hanger. The rake rod frames of the lower rake arm assembly are also spaced apart above the lower rake rods, with one end connected to the rotating shaft and the other end connected to the lower rake rod via the rake rod hanger. The demagnetizing device is located on the outer edge of the small heating disc and is used to remove magnetic foreign objects. This disc dryer effectively prevents the rake rods from bending, deforming, or even breaking at the connection point with the main shaft during use, avoids friction between the rake rods and the heating disc, and can remove magnetic foreign objects from the material.

[0007] The above measures effectively prevent the rake bar from bending, deforming, or even breaking at the connection with the main shaft during use. However, it was found during use that raw materials tend to accumulate at the connection points between the rake bar and the rotating shaft, as well as between the rotating shaft and the heating plate, leading to mixing of raw materials from different batches and affecting the consistency of the dried raw materials. At the same time, agglomeration occurs during the drying process, resulting in low drying efficiency.

[0008] In conclusion, there is an urgent need for a disc dryer for drying bromochlorohydantoin to solve the aforementioned problems. Utility Model Content
