Description

TECHNICAL FIELD

[0001] The utility model relates to a magnetic separator, especially to a broken and dispersed integrated cylinder type magnetic separator. BACKGROUND

[0002] With the continuous exploitation and utilization of mineral resources, higher requirements are put forward for the extraction and separation technology of magnetic substances in ores. Especially in the recycling process of powdery particles, effectively removing impurities such as iron powder is crucial to improve product quality and purity. Therefore, as an important screening device, the magnetic separator has been widely used in mineral processing, resource recycling and other fields. The traditional magnetic separator technology mainly relies on the action of magnetic field, so that the magnetic particles in the ore pulp are magnetized to form "magnetic groups" or "magnetic chains", and then are adsorbed on the cylinder by magnetic force.

[0003] The patent with patent publication number CN218013350U discloses a double-roller magnetic separator, which includes a vertical body, a feed inlet, and two magnetic rollers arranged in the inner cavity of the body. The two magnetic rollers are longitudinally arranged with their axes on the same vertical line. Any magnetic roller includes a magnetic system on its left or right half. The magnetic systems of the two magnetic rollers are arranged on the same side and are fixed. Any magnetic roller also includes a roller shell that wraps the magnetic system. The roller shell is made of non-magnetic material and rotates in the same direction under the drive of the transmission device. The feed inlet is located near the magnetic system of the magnetic roller at the top of the body. The above screening device directly throws the material onto the surface of the rotating magnetic roller, and realizes magnetic separation with the built-in magnetic system. The magnetic material is adsorbed and unloaded to the designated area after the roller rotates. However, this traditional magnetic separation method has significant limitations. Especially when a large amount of raw ore is accumulated, it cannot effectively break and disperse, resulting in uneven material stacking. The upper layer of the material pile may not fully contact the magnetic field, resulting in "missed selection" and reducing the comprehensiveness and efficiency of magnetic selection. SUMMARY

[0018] As shown in Figure 2 The broken roll 4 is replaceably installed in the hopper 3, and different properties of ore can be broken by selecting corresponding broken roll 4, thereby improving the broken efficiency of various ores.

[0019] As shown in Figure 2 And Figure 3 The power element includes a driven wheel 6, a driving wheel 7 and a motor 8, the driven wheel 6 is installed on the rotating shaft 5 of one of the broken rolls 4, the driving wheel 7 is installed on the rotating shaft 5 of the other broken roll 4, the driven wheel 6 and the driving wheel 7 are engaged with each other, the motor 8 is fixedly installed on the rear top of the frame 1, the motor 8 is connected with the rotating shaft 5 on the driving wheel 7 through a shaft coupling, and the motor 8 drives the broken roll 4 to rotate relative to each other and crushes the ore put in through the engagement of the driven wheel 6 and the driving wheel 7.

[0020] As shown in Figure 2As shown, openings are provided on the curved surfaces of the front and bottom sides of the outer shell 2. The front opening is the outlet for the screening of non-magnetic materials, and the bottom opening is the outlet for the screening of magnetic materials. A guide frame 12 is also provided inside the outer shell 2. The guide frame 12 is located on the inner wall of the outer shell 2. The upper plane of the guide frame 12 is a downward sloping surface. The guide frame 12 is located below the connecting slide of the outer shell 2 and the hopper 3.

[0021] like Figure 3 As shown, the outer circumference of the material distribution ring 16 is provided with multiple material distribution plates evenly spaced, and each material distribution plate can be connected to the upper side of the guide frame 12; it also includes a dispersing rod 15, which is disposed inside the sliding opening connecting the outer shell 2 and the hopper 3, and the dispersing rod 15 has a triangular prism structure.

[0022] This magnetic separator can be used when magnetic screening of ore is required. The operator first starts the motor 8. The activated motor 8 drives the corresponding shaft 5 on the drive wheel 7 to rotate counterclockwise through the coupling. The rotating drive wheel 7 meshes with the driven wheel 6, so that the corresponding shafts 5 on the drive wheel 7 and the driven wheel 6 rotate synchronously and in opposite directions.

At this time, the ore to be magnetically separated can be poured into the hopper 3. The ore poured into the hopper 3 will be crushed by the two counterclockwise rotating crushing rollers 4. The crushed ore fragments will first slide down from the discharge port at the bottom of the hopper 3. At this time, the dispersing rod 15 set at the port will divert the crushed ore fragments. The diverted ore fragments fall into the guide frame 1. 2. Under the guidance of the guide frame 12, the fragments slide down sequentially onto the distribution plate compartment on the distribution ring 16. At this time, the counterclockwise rotating distribution ring 16 will drive the movement of various crushed ore fragments. Under the attraction of the strong magnet 11, the non-magnetic ore fragments cannot be attracted by the strong magnet 11. When the non-magnetic ore fragments move with the distribution ring 16 to the front opening of the outer shell 2, they are thrown out. The operator can directly collect the non-magnetic ore at the front opening of the outer shell 2. The magnetic ore fragments will continue to follow the rotation of the distribution ring 16 under the attraction of the strong magnet 11 until the ore fragments move with the distribution ring 16 to the magnetic area gap at the bottom of the strong magnet 11. The magnetic ore fragments that lose attraction will fall from the opening of the outer shell 2, so that the operator can collect the magnetic ore fragments at the same time. This achieves the effect of integrated screening of ore crushing and dispersion. The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
