[0002] In the existing production technology of the smelting workshop, the zinc oxide produced is heat collected by the waste heat boiler, cooled by the surface cooler, and smoke collected by the bag dust collector. The flue gas is desulfurized and discharged, and the smoke is collected and stored. The cooled zinc oxide smoke is collected by the ash collection bin, and the scraper conveyor transports the smoke in the ash collection bin to the collection bin, and then transported to the cooling smoke collection bin by the water-cooled screw conveyor. The cooled zinc oxide smoke is packaged by the baler and then transported and stored.

On the other hand, during the process of transportation after packaging, there is a risk of damage to the packaging bags due to external forces, resulting in metal loss and environmental pollution caused by flying metal dust.

The top of the ash tank 2 is respectively installed with a cyclone dust collector 8 and a bag dust collector 14, and the inside of the bag dust collector 14 is provided with a flushing component 9. A drop pipe 12 is connected between the air dust collector 8 and the ash tank 2. After dust removal, the zinc oxide will fall into the drop pipe 12, and then fall into the ash tank 2 through the drop pipe 12. A flap valve 10 is installed on the drop pipe 12, and the flap valve 10 can play a cutting and throttling role. An air supply pipe 13 is connected between the cyclone dust collector 8 and the bag dust collector 14. The gas in the cyclone dust collector 8 will enter the bag dust collector 14 through the air supply pipe 13. A material guide pipe 3 is connected between the silo 1 and the feed pipe 6.
[0029] Specifically, the flushing assembly 9 includes a motor 901 installed on one side of the top of the bag-type dust collector 14 and a hollow shaft 905 arranged inside the bag-type dust collector 14 through a bearing. A plurality of water outlets 906 are provided on both sides of the hollow shaft 905, and a one-way valve 907 is installed inside the water outlet 906. A driven gear 903 is sleeved on the upper part of the outer wall of the hollow shaft 905, and a water inlet pipe 904 is inserted at the top of the hollow shaft 905. The water inlet pipe 904 can be connected to the water outlet end of an external water pump to transport water. The output end of the motor 901 is connected to a driving gear 902, and the main gear 907 is connected to the driving gear 903. The driving gear 902 is meshed with the driven gear 903. The diameter of the driving gear 902 is smaller than that of the driven gear 903. When the dust inside the bag-type dust collector 14 needs to be cleaned, the user can start the motor 901. The motor 901 will drive the driving gear 902 to rotate, and then drive the driven gear 903 to rotate. The driven gear 903 will drive the hollow shaft 905 to rotate. After the hollow shaft 905 rotates, the water inside it will enter the water outlet 906, and then flow out through the one-way valve 907, so as to flush the inner wall of the bag-type dust collector 14.

[0032] When the zinc oxide material in the ash tank 2 needs to be discharged, the zinc oxide material will fall into the rotary discharge valve 20 and then be discharged through the discharge port 11. One end of the discharge port 11 is for filling with packaging bags, and the other end is connected to compressed air to realize the filling of the tank truck. When the dust inside the bag dust collector 14 needs to be cleaned, the user can start the motor 901. The motor 901 will drive the driving gear 902 to rotate, and then drive the driven gear 903 to rotate. The driven gear 903 drives the hollow shaft 905 to rotate, and water will enter the hollow shaft 905 through the water inlet pipe 904. As the hollow shaft 905 rotates, the water inside it will flow to the one-way valve 907, and then be sprayed out through the one-way valve 907, so as to flush the inside of the bag dust collector 14.
