Description

Technical Field

[0001] The invention relates to the technical field of flow balancing devices for flotation machines, and in particular to a combined flow balancing device for flotation machines. Background Art

[0002] Flotation is a mineral processing technology widely used in the separation of fine-particle minerals. It is widely used in the separation of non-ferrous metals, ferrous metals, coal and other minerals. In addition, it also plays an important role in the petroleum, chemical and sewage treatment industries. As the carrier of the flotation process, the mechanical agitation flotation machine is one of the most important supports for flotation technology. The mechanical agitation flotation machine is generally composed of a tank body, a transmission device, a stirring mechanism, a flow equalizing device and a bubble scraping device. Through the rotation of the impeller, the inhaled or compressed air is mixed and stirred with the slurry containing the ore mud, and the flow is guided through the flow equalizing device and evenly dispersed into the flotation tank. Among them, the flow equalizing device plays a vital role in the mixing and dispersion process of gas-liquid-solid multiphase mineral flow.

[0003] At present, with the rapid development of society and economy, the demand for mineral resources is constantly increasing, which makes the mechanical stirring flotation machine become larger and larger, resulting in a significant increase in the specifications and sizes of the flow-passing parts such as the flow-equalizing device of the flotation machine, which increases the difficulty of production, manufacturing, storage and transportation, and increases production costs. In addition, the flow-passing parts such as the flow-equalizing device of the flotation machine need to be moved to the maintenance area as a whole during maintenance or repair. When a small part of the structure is damaged, the entire part can only be replaced, resulting in economic losses and waste of human resources. Summary of the invention

The two outer ring fixing plates 7 are respectively abutted against the top and bottom of the blade body 5. The two outer ring fixing plates 7 are both located at the end of the blade body 5 away from the axis of the first through hole 2.

[0033] In this embodiment, the guide is made into a split type, and a plurality of blade bodies 5 form a guide. The blade bodies 5 are butted head to tail, and then the blade bodies 5 are fixed by the inner ring fixing plate 6 and the outer ring fixing plate 7, so as to form the first through hole 2 and the second through hole 4. The slurry flows along the guide cavity 3, and the first through hole 2 and the second through hole 4 are convenient for installing other structural parts. The guide is split and fixed by the inner ring fixing plate 6 and the outer ring fixing plate 7. During use, if the flow equalizing device needs to be repaired, the inner ring fixing plate 6 and the outer ring fixing plate 7 at the top can be removed, and then the blade body 5 to be replaced can be removed from the outer ring fixing plate 7 at the bottom. There is no need to disassemble the entire flow equalizing device, and a single blade body 5 is easy to disassemble. When it is installed for the first time, the blade bodies 5 can be assembled one by one, and fewer tools are required, and it takes up less space and is easy to install.

[0034] Furthermore, the blade body 5 includes an upper wall plate 8, a lower wall plate 9 and a guide vane 10, the guide vane 10 is arranged between the upper wall plate 8 and the lower wall plate 9, a plurality of upper wall plates 8 form a first through hole 2, a plurality of lower wall plates 9 form a second through hole 4, a guide cavity 3 is formed between the upper wall plate 8 and the lower wall plate 9, an inner ring fixing plate 6 and an outer ring fixing plate 7 are abutted against the top of the upper wall plate 8, and another outer ring fixing plate 7 is abutted against the bottom of the lower wall plate 9.

[0035] In this embodiment, the structure of the blade body 5 is introduced, specifically: a guide blade 10 is installed between the upper wall plate 8 and the lower wall plate 9, and multiple blade bodies 5 are fixed by an inner ring fixing plate 6 and an outer ring fixing plate 7. The inner ring fixing plate 6 is used to connect the upper wall plate 8, an outer ring fixing plate 7 is connected to the upper wall plate 8, and the other outer ring fixing plate 7 is used to connect the lower wall plate 9.
