Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, in particular to a permanent magnet direct-driven electric drum type magnetic separator. Background Art

[0002] There are wet, dry, flat and cylindrical magnetic separators. The current beneficiation process of the magnetic separator relies on an independent motor to drive the conveyor belt to transport the ore. When the ore passes through the stationary magnetic separator, the magnetic material in the ore is attracted and screened out. The current magnetic separator and the power part are dispersed and independent, the structure is relatively dispersed, and it occupies a large area inside the device, which is easy to compress other parts in the device. Utility Model Content

[0003] The utility model aims at the deficiencies of the prior art and provides the following technical solutions:

[0004] A permanent magnet direct-drive electric drum magnetic separator comprises a machine base, a stator mechanism is fixedly mounted on the upper surface of the machine base by bolts, end covers are fixedly connected to the outer walls at both ends of the stator mechanism by bearings, a magnetic separation mechanism is fixedly mounted on the end covers by bolts, and a wiring groove is provided at the left end of the stator mechanism.

[0005] As an improvement of the above technical solution, the stator mechanism includes a shaft, an iron core and a coil. The outer wall of the shaft is clamped to the upper surface of the base through a flat key, the inner cavity of the iron core is fixedly connected to the outer wall of the shaft, and the coil is wound in the inner cavity of the outer wall of the iron core.

[0006] As an improvement of the above technical solution, the magnetic separation mechanism includes an outer cylinder, a magnetic isolation cylinder, an inner cylinder, an inner magnetic steel, an outer magnetic steel and a stainless steel protective cylinder. The two ends of the outer cylinder are fixedly connected to one end close to each other with the end cover by bolts, the outer wall of the magnetic isolation cylinder is fixedly connected to the inner wall of the outer cylinder, the outer wall of the inner cylinder is fixedly connected to the inner wall of the magnetic isolation cylinder, the outer wall of the inner magnetic steel is fixedly connected to the inner wall of the inner cylinder, the outer wall of the outer magnetic steel is fixedly connected to the inner cavity of the outer wall of the outer cylinder, and the inner wall of the stainless steel protective cylinder is fixedly connected to the outer walls of the outer cylinder and the outer magnetic steel, respectively.

[0007] As an improvement of the above technical solution, a rubber pad is installed on the lower surface of the base.

[0008] Beneficial effects of the utility model:

[0009] 1. First, the wires are used to energize the stator mechanism through the wiring groove at the left end of the stator mechanism. The internal magnetic steel inside the stator mechanism and the magnetic separation mechanism forms a magnetic field, which causes the magnetic separation mechanism to rotate and magnetically separate the materials, thereby achieving the combination of the magnetic separator and the power device, saving space inside the device, without occupying a large space, so as not to compress other internal parts, and making the arrangement of parts in the device more reasonable.

[0010] 2. The stator mechanism is powered by the wiring groove at the left end of the stator mechanism, so that a magnetic field is formed between the stator mechanism and the inner magnetic steel, thereby causing the inner magnetic steel to rotate. The rotation of the inner magnetic steel drives the inner cylinder, the magnetic isolation cylinder and the outer cylinder to rotate. The rotation of the outer cylinder causes the outer magnetic steel and the stainless steel protective cylinder to rotate to screen the materials, thereby realizing the combination of the power device and the magnetic separator, saving space inside the device, without occupying a large space, so as not to compress other internal parts, and making the arrangement of parts in the device more reasonable.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0017] See also Figure 1-4The utility model provides a technical solution: a permanent magnet direct-drive electric drum magnetic separator, comprising a machine base 1, a stator mechanism 2 is fixedly installed on the upper surface of the machine base 1 by bolts, the outer walls of the two ends of the stator mechanism 2 are fixedly connected with end covers 3 by bearings, and the end covers 3 are fixedly installed with magnetic separation mechanisms 4 by bolts, and a wiring groove 5 is opened at the left end of the stator mechanism 2. First, the wire is energized to the stator mechanism 2 through the wiring groove 5 opened at the left end of the stator mechanism 2, and the stator mechanism 2 and the internal magnetic steel 404 inside the magnetic separation mechanism 4 form a magnetic field, so that the magnetic separation mechanism 4 is rotated to magnetically separate the material, thereby achieving the combination of the magnetic separator and the power device, saving the space inside the device, and not occupying a large space, so as not to compress other internal parts, so that the arrangement of parts in the device is more reasonable.

[0018] Specifically, the stator mechanism 2 includes a shaft 201, an iron core 202 and a coil 203. The outer wall of the shaft 201 is clamped to the upper surface of the base 1 through a flat key, the inner cavity of the iron core 202 is fixedly connected to the outer wall of the shaft 201, and the coil 203 is wound in the inner cavity of the outer wall of the iron core 202.

The outer wall of the magnetic isolation cylinder 402 is fixedly connected to the inner wall of the outer cylinder 401, the outer wall of the inner cylinder 403 is fixedly connected to the inner wall of the magnetic isolation cylinder 402, the outer wall of the inner magnetic steel 404 is fixedly connected to the inner wall of the inner cylinder 403, the outer wall of the outer magnetic steel 405 is fixedly connected to the inner cavity of the outer wall of the outer cylinder 401, and the inner wall of the stainless steel protective cylinder 406 is respectively connected to the outer walls of the outer cylinder 401 and the outer magnetic steel 405. The stator mechanism 2 is fixedly connected and powered by the wiring groove 5 arranged at the left end of the stator mechanism 2, so that a magnetic field is formed between the stator mechanism 2 and the inner magnetic steel 404, and then the inner magnetic steel 404 rotates. The rotation of the inner magnetic steel 404 drives the inner cylinder 403, the magnetic isolation cylinder 402 and the outer cylinder 401 to rotate. The rotation of the outer cylinder 401 causes the outer magnetic steel 405 and the stainless steel protective cylinder 406 to rotate to screen the materials, thereby realizing the combination of the power device and the magnetic separator, saving space inside the device, and not occupying a large space, so as not to compress other internal parts, making the arrangement of parts in the device more reasonable.
