[0002] Blasting smoke suppression device is a device specially designed to reduce the hazards of dust explosion and prevent secondary explosion. Its main purpose is to limit the explosion to a limited range through effective technical means, reduce the generation and spread of smoke, and thus protect the safety of personnel and the environment. However, the existing blasting smoke suppression device has some shortcomings, such as:

[0003] Publication number: CN219061567U is a mine blasting smoke suppression device, which fills water into a water tank through a water inlet on a top plate, and uses a water pump to pump the water in the water tank through a water pipe. A support rod is connected to a support block, and the water pipe is arranged inside the support block to fix the water pipe. The water pipe sprays water through a sprinkler nozzle. Compared with the existing ordinary mine blasting device, this mine blasting smoke suppression device has a dust reduction mechanism, which will not cause dust after drilling to fly around and cause air pollution. However, the device still has certain defects.

[0004] After the blast, the device needs to be manually pushed to a place with more smoke and dust for spraying to reduce dust. Since the smoke and dust are dense and fine, the sprayed water cannot reduce all the smoke and dust. When the water droplets fall to the ground, the smoke and dust on the ground will be stirred up, which can easily choke the workers, and the air carrying the smoke and dust will still enter the workers' mouths and noses.

[0005] Therefore, we propose a blasting smoke suppression device with a back-blowing structure to solve the above-mentioned problems. Utility Model Content

[0019] 1. Through the box, piston pump body, filter plate, pulley group and scraper, when the exhaust fan draws the gas into the box, the smoke and dust in the gas are blocked by the filter plate, and the clean gas is discharged through the air outlet of the box.
