Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a device for extracting and separating tailings iron ore powder. Background Art

[0002] Iron ore is a mineral aggregate containing iron or iron compounds that can be economically utilized, and iron ore is an important raw material for steel production enterprises. Tailings are gradually separated into iron ore powder through crushing, grinding, magnetic separation, flotation and gravity separation. In this process, an extraction and separation device is required to process the tailings. However, the existing tailings iron ore powder extraction and separation device still has certain defects during use;

[0003] An iron tailings extraction and separation device proposed in application number CN202122501966.1 specifically relates to the technical field of iron tailings extraction, including a mounting frame, a crushing box is installed on the right upper end of the mounting frame, a mounting seat is fixedly installed on the middle upper end of the mounting frame, a driving mechanism is fixedly installed on the upper end of the mounting seat, a crushing mechanism is arranged in the crushing box, two connecting columns are fixedly installed on the lower end of the mounting frame, and a screening component is commonly connected to the lower ends of the two connecting columns, a feeding pipe is connected to the right lower end of the crushing box, and the feeding pipe is fixedly connected to the right part of the screening component, and three discharging pipes are fixedly installed at the lower end of the screening component at equal distances. In actual use, the iron tailings extraction and separation device drives the first rack and the second rack to collide with each other through the vertical plate to achieve the crushing of the tailings. Such a crushing method is prone to incomplete crushing, which reduces the crushing effect, and needs to be driven by a driving source alone during the crushing of the tailings and the screening process after crushing, which is not convenient for the crushing structure and the screening structure to be linked, thereby reducing the environmental protection effect.

[0004] Therefore, we propose a device for extracting and separating tailings iron ore powder in order to solve the above-mentioned problems. Utility Model Content

[0013] By adopting the above-mentioned structural design, while the servo motor drives the first crushing roller to rotate, the first crushing roller can utilize the meshing connection between the driving gear and the driven gear to drive the second crushing roller to rotate in the opposite direction, which is beneficial to the effective crushing and pulverizing of the tailings and improves the tailings treatment effect of the tailings iron ore powder extraction and separation device.

[0014] Preferably, stirring rods are installed on the rotating rod at equal angles and intervals.

[0015] The above structural design makes it easier for the rotating rod to stir the crushed tailings when driving the stirring rod to rotate, avoiding the crushed tailings from falling on the screen plate in clumps, which is beneficial for the screen plate to fully screen the crushed tailings.

[0017] Preferably, the top plate and the connecting rod form an elastic reset structure with the screening bin via a spring, and the transmission rod forms a reciprocating transmission structure with the top plate via a cam.

[0018] The above-mentioned structural design makes it easier for the vibrating screening mechanism to drive the screen plate to perform reciprocating lifting and vibration inside the screening bin, which is beneficial to the effective screening of the crushed tailings and avoids the discharge of large-particle tailings.
