A plurality of filter bags 6 are installed on the circulating feeding assembly 5 for standby, and the filter bags 6 are moved to the discharge end of the negative pressure assembly 7 for receiving by the belt drive assembly in turn. The filter bag 6 is switched by the machine instead of manual operation, which not only reduces the labor intensity of workers, but also helps to improve the replacement efficiency of the filter bag 6, thereby reducing the machine downtime, ensuring the continuous production capacity of the regenerator, and effectively improving the work efficiency.

When the filter bag 6 is connected with the negative pressure assembly 7, the electric telescopic rod 77 is elongated to drive the lifting platform 75 to move downward, and the lifting platform 75 is pressed on the connecting block 53 on the filter bag 6, so that the metal hose 74 is connected with the inside of the filter bag 6 to transport the dust;
