Description

Technical Field

[0001] The invention relates to the technical field of chemical production, in particular to a drying device for producing diphenylamine. Background Art

[0002] Diphenylamine is an important chemical raw material, primarily used in synthetic rubber antioxidants, dye intermediates, and important stabilizers. Aniline is produced using a variety of methods, including the continuous aniline process and the nitrobenzene process. The diphenylamine produced in these processes typically contains a certain amount of water and other impurities. The presence of water can affect the purity, stability, and other properties of diphenylamine. Removing water through drying equipment can improve the quality of diphenylamine, making it more suitable for subsequent processing and application requirements.

[0003] Existing devices primarily use hot air blowers to heat and dry horizontally conveyed chemical raw materials. Much of the existing technology resembles a drying device for producing 2,5-diphenylamino terephthalic acid. Patent number CN113606921A describes a structure comprising a ground-mounted base with a vertical plate mounted on top. These plates are equipped with multiple, parallel mesh conveyor belts, each driven by a motor. A heat shield houses several hot air blowers evenly distributed below the conveyor belts, and an exhaust fan is located on top of the shield. While this invention can dry chemical products such as 2,5-diphenylamino terephthalic acid, it still has room for improvement.

[0004] Existing devices mainly use hot air to heat and dry the raw materials on the conveyor belt, which makes it difficult for some devices to evenly scatter the raw materials in the high-temperature air flow, resulting in inconvenience in uniform heating and drying of the raw materials. Secondly, some devices mainly use a one-way conveying method to dry the raw materials, which makes it difficult for some devices to lift the raw materials below the inside of the warm air box to a high place, resulting in inconvenience in circulating and drying the raw materials. Finally, some devices use a hot air drying system, which makes it difficult for some devices to automatically clean the filter plate structure, resulting in clogging of some filter plates and affecting the discharge of water vapor, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a drying device for diphenylamine production is proposed. Summary of the Invention
