Description

Technical Field

[0001] The utility model belongs to the field of tailings filtration, in particular to a tailings filter for mining areas. Background Art

[0002] Tailings are solid mineral materials such as silicates or carbonates formed from the natural dehydration of tailings slurry discharged from mineral processing plants. Tailings particles vary in size and contain a high level of impurities, requiring filtration and screening before refining. A mining tailings filter is a device specifically designed for processing mine tailings. Its primary purpose is to process tailings, which contain large amounts of water and fine particles, through filtration and dehydration processes, reducing them to a solid material with a lower moisture content that is easier to handle or reuse.

[0003] For example, the Chinese utility model patent application number 2023217180538 discloses a tailings filter, which combines a dewatering screen and a drum screen. After the naturally dewatered tailings are filtered and screened by the drum screen, impurities and coarse sand are separated. The fine tailings enter the dewatering screen for further dehydration to obtain dry fine tailings, which facilitates the transportation and reuse of the tailings.

[0004] However, when conveying tailings, the thickness of the tailings on the tailings screen cannot be controlled. If it is too thick, it will cause a heavy screening burden and lead to insufficient screening accuracy.

[0005] In summary, there is a need for a filter that can evenly disperse tailings. Utility Model Content

[0006] The utility model aims to provide a tailings filter for mining areas.

[0007] The technical solution adopted by the utility model to solve the above problems is: a mining tailings filter, comprising:

[0012] Bidirectional helical blades are a specially designed screw conveying device, commonly used for applications such as material mixing. Compared to unidirectional helical blades, bidirectional helical blades can simultaneously convey materials in two opposite directions. The operating principle of bidirectional helical blades is based on the basic principles of screw conveying. An electric motor drives the central shaft through a speed reducer and coupling, which in turn rotates the helical blades. Due to the bidirectional design of the blades, the thrust of the blades can simultaneously move materials in two opposite directions. The specific direction of material flow depends on the rotation direction of the helical blades (left-hand or right-hand) and the rotation direction of the drive mechanism.

[0013] A further preferred technical solution is that: the screen frame is provided with a through slot for the tailings screen to pass through, and the tailings screen is connected to the mounting frame via a spring rod.

[0014] A further preferred technical solution is that a baffle is fixedly connected to the screen frame.

[0016] A further preferred technical solution is that it also includes a dust removal device, which includes an installation box, which is fixedly connected to the side of the installation frame, a suction fan is installed on one side of the installation box, a filter is fixedly connected to the inner wall of the installation box, the filter is in contact with the scraper, and a dust suction pipe is connected to the installation box, and one end of the dust suction pipe is connected to a dust hood.

[0019] A further preferred technical solution is that the dust hood is fixedly connected to the top of the screen frame, and a dust suction port is provided at the bottom of the dust hood.

[0020] A further preferred technical solution is that the tailings screen is arranged obliquely on the screen frame.

[0021] A further preferred technical solution is that the filter is located between the dust suction pipe port and the suction fan, and the dust suction pipe is fixedly connected to the mounting frame through a support frame.

[0022] In summary, the present invention has the following advantages:
