The invention relates to the technical field of pulse dust removal, and discloses a pulse dust removal device for asphalt stirring production, the pulse dust removal device comprises a machine body, a dust removal cloth bag and an air nozzle, the bottom of the air nozzle is fixedly connected with an air pipe, the side wall of the air pipe is provided with an air outlet, and the top side in the air pipe is fixedly connected with an air bag. A spring is fixedly connected to the top of the inner side of the air bag, a sliding block is fixedly connected to the bottom of the air bag, and an exhaust groove is formed in the sliding block. The air bag expands to promote the sliding block to move downwards, the sliding block exhausts pulse air, the air bag can continuously drive the sliding block to move downwards due to the fact that the speed of the air entering the air bag is larger than the exhausting speed, the air exhausting groove can release pressurized air every time the air exhausting groove passes through one row of air exhausting holes, and the cloth bag is impacted; and dust on the outer side of the cloth bag is blown off, so that the high-pressure state can still be kept when the pulse gas is transmitted to the bottom of the cloth bag, and the influence of reduced gas pressure on the dust removal effect is avoided.
本发明涉及脉冲除尘技术领域，且公开了一种沥青搅拌生产用脉冲除尘装置，包括机体、除尘布袋和喷气嘴，所述喷气嘴的底部固定连接有气管，所述气管的侧壁开设有出气孔，所述气管内部的顶侧固定连接有气囊，所述气囊内侧的顶部固定连接有弹簧，所述气囊的底部固定连接有滑块，所述滑块的内部开设有排气槽。本发明通过的气囊膨胀促使滑块下移，滑块将脉冲气体排出，由于气体进入气囊中的速度大于排出的速度，使得气囊能不断的带动滑块下移，致使排气槽每经过一排出气孔时均能释放增压的气体，对布袋进行冲击，促使布袋外侧的灰尘被吹落，使得脉冲气体被传输到布袋的底部时仍然能保持高压状态，避免了气体压力减小影响除尘效果。
