Abstract

This utility model relates to the field of active pharmaceutical ingredient (API) intermediates technology, specifically a ventilation device for safe production of API intermediates. It includes a ventilation box with a hinged door on its front. Inside the ventilation box, several arc-shaped support frames are fixedly connected from top to bottom, and a filter mechanism is mounted on each arc-shaped support frame. A diversion pipe is fixedly connected to the right side of the ventilation box, and a sealing mechanism is provided between the diversion pipe and the filter mechanism. A locking mechanism is provided between the ventilation box and the filter mechanism. This utility model, through the combined use of the locking mechanism and the arc-shaped support frames, achieves a stable fixation of the filter mechanism, solving the safety hazard of filter structure displacement or loosening due to vibration during fan operation, and improving the reliability of equipment operation.
