Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing equipment, and in particular to a fine screening mineral processing equipment. Background Art

[0002] Ore dressing is the process of selecting useful minerals from collected raw minerals based on their physical and chemical properties. It involves various methods, including gravity separation, flotation, magnetic separation, and electrostatic separation. Magnetic separators, among others, utilize magnetic fields to separate magnetic and non-magnetic materials based on the magnetic properties of various ores. They are commonly used to separate fine-grained magnetic ores or to remove magnetic materials mixed with non-magnetic materials.

[0003] The magnetic separator uses permanent magnets or electromagnets to generate a magnetic field. After being crushed and ground, the ore enters the magnetic field area through a conveying device. The magnetic ore is adsorbed on the drum of the magnetic separator and then carried out of the magnetic field area as the drum rotates and discharged from the discharge port. In actual production, the ore on the conveying device often piles up together, making it difficult for the magnetic ore buried at the bottom to be adsorbed on the drum, affecting the fineness of the ore screening. Therefore, the utility model proposes a fine screening and beneficiation device. Utility Model Content

[0004] The utility model provides a fine screening and beneficiation device, which solves the problem of poor fineness of magnetic ore screening in magnetic beneficiation devices in the related art.

[0005] The technical solution of the present utility model is as follows: A fine screening and mineral processing device comprises a screening box, a feed port, two discharge ports, a magnetic separation component, a conveying mechanism, a material shifting component, a connecting frame and a vibration mechanism. A screening cavity is provided inside the screening box. The conveying mechanism is provided in the screening cavity for conveying the mineral material to the magnetic separation component. The material shifting component is provided on the conveying mechanism for shifting the mineral material on the conveying mechanism evenly. The connecting frame is provided between the conveying mechanism and the magnetic separation component, and the connecting frame is fixedly connected to the inner bottom wall of the screening cavity. The vibration mechanism is provided at the bottom of the magnetic separation component for lifting the accumulated mineral material.

[0006] Preferably, the vibration mechanism includes a second motor, a rotating shaft, a sorting platform, a cam and a spring. The second motor is installed on the outer wall of the screening box. The screening box is rotatably connected to the rotating shaft. One end of the rotating shaft passes through the screening box and is fixedly connected to the output end of the second motor. The sorting platform is slidingly connected to one end of the connecting frame close to the magnetic separation component. A plurality of cams are fixedly connected to the rotating shaft. The top ends of the plurality of cams are all in contact with the bottom end of the sorting platform. A plurality of springs are installed between the bottom end of the sorting platform and the inner bottom wall of the screening chamber.

[0007] Preferably, the conveying mechanism includes a motor 1, a driving roller, a driven roller and a conveyor belt. The motor 1 is installed on the outer wall of the screening box. The driving roller and the driven roller are both rotatably connected to the inner wall of the screening chamber. One end of the driving roller passes through the screening box and is fixedly connected to the output end of the motor 1. The conveyor belt is sleeved on the outside of the driving roller and the driven roller.

[0008] Preferably, the material-dispensing assembly includes a material-dispensing roller, a driven wheel, a driving wheel and a transmission belt. The material-dispensing roller is rotatably connected to the inner wall of the screening chamber, and the material-dispensing roller is fixedly connected to the driven wheel, and the driving roller is fixedly connected to the driving wheel, and the transmission belt is sleeved on the outside of the driving wheel and the driven wheel.

[0009] Furthermore, a plurality of material-moving pieces are installed on the material-moving roller.

[0010] Furthermore, the top ends of the connecting frame and the sorting table are both configured as inclined surfaces.

[0011] Furthermore, a sealing strip is provided on the connection frame at a position where the connection frame is slidably connected to the sorting table.

[0012] Furthermore, both sides of the sorting table are fixedly connected with a material blocking plate.

[0013] Furthermore, the top end of the connecting frame is located below the edge of the conveyor belt.

[0014] Furthermore, sealing rings are provided at positions on the screening box that are rotatably connected to the active roller and the rotating shaft.

[0015] The beneficial effects of the utility model are:

[0016] In the utility model, when the mineral material needs to be magnetically screened, the active roller is driven to rotate by the motor 1, and the active roller drives the conveyor belt to transport the mineral material backward. The motor 1 drives the active roller to rotate and drives the material-discharging roller to rotate at the same time. The material-discharging roller levelly spreads the mineral material accumulated on the conveyor belt, and then the mineral material falls onto the sorting table through the connecting frame. The rotating shaft is driven to rotate by the motor 2, and the rotating shaft drives the cam to rotate. The sorting table rises and falls with the rotation of the cam, and under the action of the spring, the sorting table continuously swings up and down, thereby lifting the mineral material on the sorting table.

[0017] Compared with the problem of poor screening fineness of magnetic ore in existing magnetic mineral separation devices, in the utility model, the material can be evenly distributed on the conveyor belt through the material shifting component, and the accumulated ore can be lifted up when passing through the magnetic separation component through the vibration mechanism, so that the magnetic ore at the bottom can also be adsorbed by the magnetic separation component, thereby improving the screening accuracy of the mineral separation device.
