[0002] Iron concentrate is mainly used in the production of steel, therefore its quality and quantity are closely related to the quality and quantity of steel. Among these processes, slurry filtration is one of the core steps in iron concentrate production; the essence of filtration is to achieve solid-liquid separation.

[0003] Since mineral slurry is a liquid mixture of solid raw materials such as ores and clays with water and other auxiliary agents, current filtration methods utilize the pressure difference across the filter media to achieve solid-liquid separation. Commonly used equipment includes various types of vacuum filters and filter presses.

[0004] However, the current slurry still contains a small amount of larger solids before filtration, which can easily lead to damage to the filter media during the filtration process. Utility Model Content

[0005] To address the technical problem that existing technologies easily damage the filter media when filtering ore slurry, this utility model provides a filtration device for iron concentrate processing. By filtering larger solids in the ore slurry first, it has the advantage of not causing damage to the filter media.

[0040] Example:

[0041] See Figure 1 , Figure 2 and Figure 3 This embodiment discloses a filtration device for iron concentrate processing, including a frame (not shown in the figure), support wheels 1, rollers 2, cover plates 3, feed troughs 4, motors 5, baffles 6, and drive components. Specifically, there are multiple support wheels 1, all of which are mounted on the frame, and the axes of all support wheels 1 are parallel to each other.

[0042] The roller 2 has multiple filter holes 7, all of which are closely distributed. The roller 2 is cylindrical, with openings at both ends, and is arranged along the water direction.

[0043] Both ends of the roller 2 are respectively matched with the wheel surfaces of multiple support wheels 1, so that the roller 2 can be fixed in relative position through the support wheels 1, and the roller 2 can rotate around its own axis on the support wheels 1.

[0044] The motor 5 is fixedly mounted on the frame, and a gear is provided on the output shaft of the motor 5. At the same time, a gear ring is provided on one end of the drum 2, and the gear meshes with the gear on the output shaft of the motor 5. Thus, the motor 5 can directly drive the drum 2 to rotate. In addition, the speed of the output shaft of the motor 5 can be controlled, so the speed of the drum 2 can also be controlled.

[0045] A cover plate 3 is provided at one end of the roller 2, and a baffle plate 6 is provided at the other end. Both the cover plate 3 and the baffle plate 6 are circular and have the same diameter, which is greater than or equal to the diameter of the roller 2. The cover plate 3 and the baffle plate 6 are coaxially arranged with the roller 2.

[0046] The cover plate 3 is fixedly mounted on the frame. There is a gap between the cover plate 3 and the end of the drum 2. A feed inlet is provided on the upper half of the cover plate 3. A feed trough 4 is provided on the feed inlet. The feed trough 4 is fixedly mounted on the frame. The slurry that needs to be pre-filtered can be directly added into the drum 2 through the feed trough 4.

[0047] The top of the baffle 6 is rotatably connected to the frame. The shaft of the baffle 6 on the frame is set in the horizontal direction. The output end of the drive component is connected to the baffle 6 and can directly drive the baffle 6 to rotate on the frame.

[0048] During use, the motor 5 directly drives the drum 2 to rotate continuously, and then the slurry is introduced into the drum 2 through the feed chute 4. The slurry passes through the filter holes 7 on the drum 2, and larger solids remain in the drum 2. After the filtration work has been carried out for a certain period of time, the baffle 6 is opened by the drive assembly, and then the larger solids in the drum 2 can be cleaned.

[0049] In this technical solution, preliminary filtration can be performed between multiple slurry filters to remove larger solids, thereby avoiding damage to the filter media during slurry filtration.

[0050] In one specific embodiment:

[0051] In order to better fix the relative position of the roller 2 in the frame, the wheel surface of the support wheel 1 is set with a concave positioning groove structure. Then, a positioning ring is set at each end of the roller 2 and the positioning ring is locked in the positioning groove, thereby restricting the movement of the roller 2 in its axial direction.

[0052] Preferably, all support wheels 1 are located in the lower half of the roller 2 to provide support for the roller 2.

[0053] In another specific embodiment:

[0054] Two guide plates 8 are respectively provided on both sides of the drum 2. The guide plates 8 are arc-shaped, and there is a gap between the bottoms of the two guide plates 8. The tops of the guide plates 8 are close to the upper half of the drum 2. The guide plates 8 are fixedly mounted on the frame. By providing a guide plate 8 on each side of the drum 2, the slurry filtered from the drum 2 can be collected below the drum 2.

[0055] In another specific embodiment:

[0056] The drive assembly includes a connecting rod 9 and a hydraulic cylinder 10. The connecting rod 9 is located on the side of the baffle 6 away from the roller 2 and is arranged in a horizontal direction. The connecting rod 9 is located in the upper half of the baffle 6 and has a gap with the rotating shaft of the baffle 6.

[0057] The length of the connecting rod 9 is greater than the diameter of the roller 2. A hydraulic cylinder 10 is provided at each end of the connecting rod 9. Specifically, the piston rod end of the hydraulic cylinder 10 is rotatably connected to the end of the connecting rod 9 and is perpendicular to each other. One end of the cylinder body of the hydraulic cylinder 10 is rotatably connected to the frame, and one end of the cylinder body of the hydraulic cylinder 10 extends in a downward inclined direction.

[0058] A hydraulic cylinder 10 is provided at each end of the connecting rod 9, and the two hydraulic cylinders 10 are arranged symmetrically.

[0059] In this embodiment, the two hydraulic cylinders 10 move synchronously. When the piston rod of the hydraulic cylinder 10 extends, it acts directly on the end of the connecting rod 9. The connecting rod 9 drives the baffle 6 to rotate on the frame, thereby realizing the opening and closing of the baffle 6 at the end of the roller 2.

[0060] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
