AI Technical Summary
Technical Problem
In the existing antimony ingot smelting process, uneven airflow distribution causes some filter bags to be overloaded, affecting dust removal efficiency, and the filter cartridges are prone to clogging, reducing the service life of the equipment.
Method used
The system employs a dust collection device, which, through the cooperation of a negative pressure fan and a regular fan, achieves uniform airflow distribution. It also utilizes a sponge ring and heater assembly to clean the filter cartridge, preventing clogging and improving filtration efficiency and equipment lifespan.
Benefits of technology
It achieves uniform airflow distribution, avoids local overload, extends the service life of the filter cartridge, and improves overall filtration efficiency and impurity recovery.

Abstract
The invention belongs to the technical field of smoke dust recycling, and discloses an antimony outlet smoke dust recycling device and method in the antimony ingot smelting process, the antimony outlet smoke dust recycling device comprises a bag-type dust collector shell, a motor is started, the motor drives a rotating shaft and a negative pressure fan to rotate, and negative pressure is generated downwards in the rotating process of the negative pressure fan; negative pressure enters the multiple conical pipes through the conical hopper and the six-pipe barrel and enters the multiple filter element barrels through the multiple conical pipes respectively, so that negative pressure is generated in the filter element barrels at the same time, airflow can be evenly distributed and enter the filter element barrels, each filter element barrel can effectively participate in the filtering process, and the filtering efficiency is improved. The overall filtering efficiency is improved. When the rotating shaft rotates, the fan is driven to rotate, so that the fan disturbs air flow, smoke entering the shell of the bag-type dust collector flows upwards along the bottom of the special-shaped barrel, and the smoke can be dispersed all around in the flowing process through stirring of the fan, so that the smoke suction uniformity of each filter element barrel is further promoted.
