AI Technical Summary

Technical Problem

Existing double cone dryers are not suitable for adding salicylic acid to wet materials during the drying process under vacuum conditions, which increases the number of drying and unloading operations and affects efficiency.

Method used

A double-cone dryer for anti-caking salicylic acid was designed. Through the cooperation of a horizontal feeding pipe and a feeding sleeve, the wet material can be continuously added. The internal scraper and agitator is driven by a drive mechanism to rotate and scrape off the adhering material, simplifying the unloading process.

Benefits of technology

This allows for the easy addition of salicylic acid to wet materials during the drying process, reducing the number of drying and unloading operations and improving drying efficiency.

Abstract

The utility model relates to the technical field of double-cone drying machines, in particular to an anti-caking double-cone drying machine for salicylic acid, which comprises a support frame, a double-cone drying tank is transversely and rotatably connected onto the support frame, a feeding pipe and a breather pipe are respectively arranged on the left side and the right side of the double-cone drying tank, and the feeding pipe is communicated with the inside of the double-cone drying tank. An anti-caking inner scraping stirring frame attached to the inner side wall of the double-cone drying tank is arranged in the double-cone drying tank, the double-cone drying device further comprises a driving mechanism for driving the anti-caking inner scraping stirring frame to rotate, a feeding sleeve with a trough in the middle is arranged in the feeding pipe in a sealed rotating and sliding fit mode, and the top of the feeding pipe fixedly communicates with a hopper matched with the trough. According to the anti-caking device, salicylic acid wet materials can be conveniently added in the drying process, then the drying and discharging times are reduced, and the drying efficiency is improved.
