Description

Technical Field

[0001] This utility model relates to a bag-breaking device and a flux feeding device for its application, specifically belonging to the field of pyrometallurgical technology for anode mud. Background Technology

[0002] Flux plays a crucial role in pyrometallurgical processes, primarily by: lowering melting temperature and improving smelting efficiency; controlling melt flow and increasing impurity separation efficiency; controlling impurity flow direction and slag formation; and controlling slag viscosity and density. In anode mud pyrometallurgical processes, the required amount of flux is small, and it is stored using either bulk stockpiling or ton bag packaging.

[0003] In the pyrometallurgical process of anode mud, the traditional method of flux feeding involves hoisting ton bags to the operating platform and manually opening them with knives. During this process, the knives can easily injure operators if they are not careful; material dust spills out during manual bag opening, also posing a risk; after opening, the material accumulates on the operating platform and needs to be manually transferred to the unloading hopper, increasing the labor intensity; and during manual material transfer, the particle size of the material is not screened and the flow rate cannot be controlled, reducing the uniformity and stability of flux addition. Based on these issues, this invention proposes a flux feeding device. Summary of the Invention

[0004] In view of the above situation, this utility model proposes a bag breaking device and a flux feeding device for its application to overcome the problems existing in the current ton bag feeding.

[0005] The present invention provides a bag-breaking device (9) consisting of four blades arranged in a cross shape and fixed at the central axis inside the bag-breaking chamber (3).

[0006] The upper part of the blade is an inverted right triangle, and the lower part is a rectangle, and it is fixed to the bottom of the bag breaking chamber (3) by bolts.

[0007] A flux feeding device consists of a lug device (1), a support device (2), a bag breaking chamber (3), a valve assembly (4), a flange assembly (5), a discharge chamber (6), a flux receiving device (7), a lifting device (8), a bag breaking device (9), a screen assembly (10), a frame (11), a ton bag lifting hook (12), an operating platform (14), and a chute (15);

[0008] A lifting device (8) is provided on the frame (11), and a ton bag lifting hook (12) is provided below the lifting device (8); the bag breaking bin (3) is supported by the support device (2), and two sets of hanging ear devices (1) are symmetrically fixed on the inner wall of the upper bin opening of the bag breaking bin (3) for easy lifting. A bag breaking device (9) is fixedly installed in the bin, and a valve assembly (4) is provided at the discharge port below the bin; the discharge bin (6) is fixed on the operating platform (14) through the flange assembly (5), and the chute (15) provided below the conical bin cavity is connected to the flux receiving device (7).

[0009] The support device (2) is fixedly supported on the operating platform (14).

[0010] The valve assembly (4) is a slide gate valve.

[0011] The fixed screen assembly (10) is fixed to the outer edge of the upper opening of the discharge bin (6) by four sets of symmetrically arranged bolts.

[0012] The center of the screen assembly (10) at the top of the bag breaking bin (3) is directly opposite to the top of the discharge bin (6).

[0013] The beneficial effects of this utility model are as follows: By setting up a bag-breaking device, the flux feeding device of this utility model allows the material after the bag is broken to flow directly into the bag-breaking hopper by its own weight, avoiding the spillage of material dust and avoiding the possible injury to operators caused by manual use of bag-breaking knives. This improves the efficiency of bag-breaking operations and personnel safety, and reduces labor intensity. By setting up a screen assembly, materials with qualified particle sizes are screened out and flow into the discharge hopper, improving the stability of material particle size.
