The invention relates to the technical field of
ceftriaxone sodium production devices, and provides a
ceftriaxone sodium crude product filtering device which comprises a gradient filtering
tower and a deep purification box, the deep purification box is communicated with the gradient filtering
tower, and the gradient filtering
tower is used for carrying out
solid-liquid separation on a
ceftriaxone sodium crude product; the deep purification box is used for purifying
ceftriaxone sodium crystal particles; the gradient filter tower comprises a tower body, the tower body is composed of a plurality of tower
layers, the adjacent tower
layers are communicated through flow guide holes, each tower layer is provided with a conical filter screen and an automatic scraping and collecting
assembly, and each automatic scraping and collecting
assembly comprises a cleaning anti-blocking scraper blade and a wet
filter cake collecting tank. And the cleaning anti-blocking scraping plate is used for scraping wet filter cakes attached to the conical filter screen to the wet
filter cake collecting tank. Wet filter cakes attached to the conical filter screen can be automatically scraped in time, the blocking risk is reduced, the automatic scraping and collecting
assembly can input scraped
solid crystal particles into the deep purification box, the discharging efficiency is improved, and the product
pollution risk is reduced.
