[0036] The principle of baghouse dust collectors is to use fiber filtration and surface interception to filter copper smelting dust. Then, in conjunction with a pulse blowing device, the surface dust layer is peeled off. The peeled dust falls into the ash hopper due to gravity and is centrally processed by a pneumatic ash conveying device.

[0037] However, due to the high moisture content of copper smelting dust, when the collected dust has a high moisture content, it can significantly impact the pneumatic dust conveying system. This can cause the transport pipes to become clogged with moisture, affecting the operation of the dust collection device and impacting production efficiency. Furthermore, the high moisture content of copper smelting dust can also affect subsequent production processes, impacting product quality.

[0054] Specifically, the drying and dust collection device for copper smelting dust also includes a receiving hopper 9; the pneumatic dust conveyor 4 is connected to the receiving hopper 9 through a pipeline and is used to transport dust into the receiving hopper 9.

[0055] In this embodiment, four dust collectors are pneumatically driven to transport the dust to the receiving hopper 9 to facilitate subsequent construction.

[0056] The controller 5 establishes electrical connections with the bag filter 1, heat exchanger 2, screw conveyor 3, and pneumatic ash conveyor 4, respectively.
