Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, in particular to a preselection crawler magnetic separator for ore particles. Background Technique

[0002] Magnetic separators are used to remove iron powder and the like from recycled powdery particles. Magnetic separators are widely used in resource recovery, wood industry, mining industry, kiln industry, chemistry, food and other workshops. They are suitable for wet magnetic separation of materials such as magnetite, pyrrhotite, roasted ore, ilmenite, etc. with a particle size of less than 3 mm, and are also used for iron removal operations of materials such as coal, non-metallic minerals, and building materials. They are one of the most widely used and highly versatile machine types in the industry.

[0003] When the existing crawler magnetic separator feeds materials, the ore from a distance is sent onto the conveyor belt inside the crawler magnetic separator through a conveyor belt. Due to the height difference between the two, the ore will impact the conveyor belt inside the magnetic separator under the action of gravity, greatly reducing the service life of the magnetic separator.

[0004] In order to solve the above problems, we made improvements and proposed a preselection crawler magnetic separator for ore particles. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model provides a preselection crawler magnetic separator for ore particles, including a conveyor belt. A magnetic separation device is installed on the right side of the conveyor belt, and a housing is installed on the left side of the conveyor belt. The inner top of the housing is hinged with a second inclined plate. The lower end surface of the second inclined plate is hinged with a plurality of telescopic electric cylinders, and the bottom ends of the telescopic electric cylinders are hinged to the inner side wall of the housing. The bottom of the housing is hinged with a first inclined plate. A lifting mechanism is arranged on the left side of the top end of the first inclined plate, and the right end of the first inclined plate is arranged at the discharge port of the housing.

Detailed implementation

[0021] The following is a description of the preferred embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0022] Embodiment: As Figures 1-3 shown, a preselection crawler magnetic separator for ore particles includes a conveyor belt 1. A magnetic separation device 2 is installed on the right side of the conveyor belt 1, and a housing 3 is installed on the left side of the conveyor belt 1. The inner top of the housing 3 is hinged with a second inclined plate 15. A plurality of telescopic electric cylinders 18 are hinged to the lower end surface of the second inclined plate 15, and the bottom ends of the telescopic electric cylinders 18 are hinged to the inner side wall of the housing 3. The bottom of the housing 3 is hinged with a first inclined plate 13. A lifting mechanism is arranged on the left side of the top end of the first inclined plate 13. The right end of the first inclined plate 13 is arranged at the discharge port of the housing 3. The left bottom of the housing 3 is fixedly connected with an extension housing 4, and the left end of the first inclined plate 13 is arranged inside the extension housing 4;

[0023] The ore falls into the interior of the housing 3 and then collides with the second inclined plate 15, consuming the kinetic energy of the ore. The telescopic electric cylinders 18 expand and contract cyclically, opening and closing the gap between the second inclined plate 15 and the housing 3. The ore falls onto the first inclined plate 13 from the gap and then slides out of the housing 3 along the first inclined plate 13. The kinetic energy of the ore is reduced in two stages, playing a role in protecting the conveyor belt 1 and extending the service life of the equipment. The lifting mechanism works to drive the left end of the first inclined plate 13 to move up and down, which can assist in feeding the ore from the first inclined plate 13.

[0024] Specifically, as Figure 2 and Figure 3As shown in the figure, the lifting mechanism includes a motor 8, and the motor 8 is fixedly connected to the top end of the extension shell 4. The output end of the motor 8 is fixedly connected to a turntable 9. A connecting block 10 is hinged at a position near the circumference on the left side of the turntable 9. The bottom end of the connecting block 10 is slidably connected to a connecting rod 11. The bottom end of the connecting rod 11 is fixedly connected to a plurality of connecting ropes 12, and the bottom ends of the connecting ropes 12 are fixedly connected to the upper end surface of the first inclined plate 13. Limit frames 7 are fixedly connected to both the front and rear sides of the top end of the extension shell 4, and the two limit frames 7 are respectively slidably connected to the front and rear ends of the connecting rod 11. When the motor 8 works to drive the turntable 9 to rotate, the connecting block 10 makes a circular motion, thereby driving the connecting rod 11 to drive the connecting ropes 12 to move up and down, so that the left end of the first inclined plate 13 moves up and down.

[0025] Specifically, as Figure 1 shown in the figure, a feeding funnel 5 is fixedly connected to the top end of the housing 3. A plurality of elastic plates 6 arranged up and down are fixedly connected to the inside of the feeding funnel 5, and the elastic plates 6 are arc-shaped plates. By expanding the feeding opening of the feeding funnel 5, after the ore enters the feeding funnel 5, it acts on the elastic plates 6, and the elastic plates 6 deform, consuming part of the kinetic energy of the ore and further reducing the impact of the ore on the conveyor belt.

[0026] Specifically, as Figure 3 shown in the figure, a plurality of guide rods 16 are fixedly connected to the upper end surface of the first inclined plate 13, and a plurality of deceleration rods 17 are fixedly connected to the top end of the second inclined plate 15. The guide rods 16 guide the ore to prevent the ore from sliding sideways when sliding along the first inclined plate 13 and then moving out of the conveyor belt. The deceleration rods 17 decelerate the ore sliding on the second inclined plate 15, further reducing the kinetic energy of the ore.

[0027] Specifically, as Figure 3 shown in the figure, a telescopic plate 14 is installed at the opening where the extension shell 4 is connected to the housing 3, and the bottom end of the telescopic plate 14 abuts against the upper end surface of the first inclined plate 13. The telescopic plate 14 is arranged between the extension shell 4 and the housing 3 to prevent the ore from entering the extension shell 4.

[0028] Working principle: After the ore enters the feeding funnel 5, it acts on the elastic plates 6, and the elastic plates 6 deform, consuming part of the kinetic energy of the ore. The ore falls into the interior of the housing 3 and then collides with the second inclined plate 15, consuming the kinetic energy of the ore. The telescopic cylinder 18 extends and retracts cyclically, opening and closing the gap between the second inclined plate 15 and the housing 3. The ore falls from the gap onto the first inclined plate 13. The motor 8 works to drive the turntable 9 to rotate, making the connecting block 10 make a circular motion, thereby driving the connecting rod 11 to drive the connecting ropes 12 to move up and down, making the left end of the first inclined plate 13 move up and down, causing the first inclined plate 13 to vibrate, and then making the ore slide out of the housing 3 along the first inclined plate 13.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
