Description

Technical Field

[0001] The utility model relates to the technical field of dichlorohydantoin production, and particularly relates to an efficient drying mechanism for dichlorohydantoin production. Background Technique

[0002] Dichlorohydantoin is an important organic intermediate and has various uses in the chemical industry. Its application scope includes fields such as organic synthesis, pesticide production, and pharmaceutical intermediates. In the production process of dichlorohydantoin, the drying step is very important for obtaining a pure final product. The drying process aims to remove moisture and solvent residues in the reaction product and improve the purity and stability of dichlorohydantoin.

[0003] Currently, the drying methods for dichlorohydantoin are usually evaporation drying, vacuum drying, spray drying, freeze drying, etc. Among them, spray drying atomizes the dichlorohydantoin solution into fine droplets and quickly contacts with hot air to complete the drying process, making the working efficiency of the device relatively high. However, in the use of some current devices, the atomized dichlorohydantoin may stay on the inner wall of the drying box, making it more laborious for operators to clean the inside of the drying box. Although some current devices can scrape the dichlorohydantoin on the inner wall through devices such as cleaning plates arranged inside the box, when the above devices are used, since hot air needs to be generated to dry dichlorohydantoin, the energy consumption of the device increases, and the energy consumption of the device may be further increased by setting components such as cleaning plates, increasing the operating cost of the device. Therefore, an efficient drying mechanism for dichlorohydantoin with low energy consumption is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide an efficient drying mechanism for dichlorohydantoin production, which can solve the problem of relatively high energy consumption of some current dichlorohydantoin drying devices.

By controlling the start of the bidirectional motor 801, the fan blade 808 is driven to rotate through the settings of the first transmission wheel 802, the second transmission wheel 803 and the transmission belt 810, thereby generating wind power. By controlling the setting of the heating resistance wire 809, the air can be heated, so that the fan blade 808 can drive the hot air.

When controlling the start of the bidirectional motor 801, the drying rod 12 is driven to rotate, so that the drying rod 12 can drive the nozzle 14 to rotate, and then the nozzle 14 can dry a larger range of dichlorohydantoin, improving the working efficiency of the device to a certain extent. At the same time, the cleaning plate 15 can be driven to scrape the inner wall of the drying box 1 to prevent dichlorohydantoin from remaining on the inner wall of the drying box 1, so as to better collect dichlorohydantoin.
