Description

Technical Field

[0001] This utility model belongs to the field of hydrometallurgical technology, specifically relating to a powder ton bag breaking device. Background Technology

[0002] Package breakers are mainly used for breaking up packages of solid granular and powdery materials. In hydrometallurgical processes, they are widely used in the leaching and feeding stages of cobalt, nickel, and manganese salts. The feeding stage is a core step before leaching, directly affecting leaching efficiency, metal recovery rate, production safety, and production cycle time. It mainly includes: raw material feeding (ore, intermediate products) and reagent feeding (acids, reducing agents, oxidizing agents, etc.). In cobalt hydrometallurgy, package breakers are not only a crucial "entry point" for improving feeding efficiency but also core equipment for ensuring production safety and environmental compliance. Current technology involves hanging the package with hooks, hoisting it to the silo opening, and then manually opening the package with tools to release the material. This method is labor-intensive, and the falling material easily generates a large amount of dust, resulting in a poor workshop environment. Summary of the Invention

[0003] To overcome the problems of manual opening and unloading of ton bags using tools in the prior art, which is labor-intensive and generates a lot of dust during the material's fall, resulting in a poor workshop environment, this utility model provides a powder ton bag breaking device. The ton bag material is hung up with hooks and transported to the unloading cylinder 1, where it is broken and unloaded by a conical cutter head 5 and a blade connecting plate 4. A cylinder cover 2 is provided at the top, and the entire device is sealed during the feeding process. Dust is sucked up by an annular dust suction groove 6, creating a negative pressure inside the unloading cylinder 1 to prevent dust from overflowing. This device avoids manual operation with tools, reduces the labor intensity of employees, improves the safety of employee operation, avoids the risk of tools falling into the breaking machine, and improves feeding efficiency.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A powder ton bag breaking device mainly includes a feeding cylinder 1, a cylinder cover 2, a hydraulic cylinder 3, a blade connecting plate 4, a conical cutter head 5, and an annular dust collection groove 6. The feeding cylinder 1 is installed on the top of the silo via a flange. A lever arm 21 is provided on one side of the cylinder cover 2, and the cylinder cover 2 is hinged to the feeding cylinder 1 via the lever arm 21. The two ends of the hydraulic cylinder 3 are respectively hinged to the side of the feeding cylinder 1 and the end of the lever arm 21. The cylinder cover 2 is provided with a strip-shaped opening 10 to prevent it from getting dry with the lifting rope. The bottom ends of the four blade connecting plates 4 are evenly installed inside the feeding cylinder 1, and the top ends of the four blade connecting plates 4 are connected and fixed to each other. The four blade connecting plates 4 are generally conical in shape. The conical cutter head 5 is installed on the top of the four blade connecting plates 4. An annular dust collection groove 6 is installed on the outer wall of the top of the feeding cylinder 1, and a dust collection port 11 communicating with the annular dust collection groove 6 is provided on the inner wall of the feeding cylinder 1. The annular dust collection groove 6 is connected to the dust suppression equipment in the workshop via a fan.

[0005] Furthermore, a bracket 12 is installed at the bottom of the inner end of the feeding cylinder 1, a turntable 13 is installed on the bracket 12, a centrifugal throwing plate 14 is provided on the turntable 13, and a motor 15 is installed on the outer wall of the feeding cylinder 1. The turntable 13 and the motor 15 are connected by a belt drive structure.

[0006] Furthermore, the belt drive structure is covered with a dust cover 16.

[0007] Furthermore, the inner side of the top of the feeding cylinder 1 is provided with an annular water pipe 7, which is connected to the workshop water supply system, and a nozzle is provided on the annular water pipe 7.

[0008] Furthermore, the blade connecting plates 4 are connected by reinforcing support strips 17.

[0009] The beneficial effects of this utility model are:

[0010] This invention involves hanging ton bags of material with hooks and hoisting them into a feeding cylinder. The conical cutter head and blade connecting plate inside the cylinder then break up the bags and discharge the material. A cylinder cover at the top ensures the entire equipment remains sealed during feeding. A ring-shaped dust extraction groove creates negative pressure inside the feeding cylinder, preventing dust from overflowing. This design eliminates the need for manual operation with tools, reducing labor intensity, improving worker safety, mitigating the risk of tools falling into the bag-breaking machine, and increasing feeding efficiency.
