The invention discloses an anti-blocking nozzle for continuous casting secondary cooling, and belongs to the technical field of continuous casting production. The anti-blocking nozzle comprises a nozzle body with a spraying hole, a nozzle core is arranged in the nozzle body and located at the distal end distal from the spraying hole, an air inlet channel is formed between the nozzle core and the nozzle body, a water inlet channel and a water dividing hole communicating with the water inlet channel and the air inlet channel are formed in the nozzle core, and a negative pressure ring located onthe upper edge of an opening of the water dividing hole is arranged outside the nozzle core. Compressed air enters from the air inlet channel and then is blocked by the negative pressure ring to flowback at the position of the water dividing hole to form negative pressure, and then cooling water in the water dividing hole is sucked out, scattered and atomized; and the anti-blocking nozzle effectively solves the problem th
