Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, in particular to a magnetic separator unloading device. Background Art

[0002] A magnetic separator is a screening device used to remove iron and other fines from recycled powdered particles. After the slurry flows through the feed box and into the trough, the water flow from the feed water pipes loosens the ore particles and enters the feed area of the trough. The magnetic field attracts the magnetic particles, forming "magnetic clusters" or "magnetic chains." These "magnetic clusters" or "magnetic chains" are attracted to the magnetic poles within the slurry and are attracted to the cylinder. Because the polarity of the magnetic poles alternates along the direction of the cylinder's rotation and remains stationary during operation, the "magnetic clusters" or "magnetic chains" generate magnetic agitation as the cylinder rotates. Non-magnetic minerals such as gangue are dislodged from these "magnetic clusters" or "magnetic chains" during this churning, ultimately attracting the "magnetic clusters" or "magnetic chains" on the cylinder's surface, which constitute the concentrate. Magnetic separators are widely used in resource recycling, the timber industry, mining, kiln industry, chemical industry, food industry and other factories. They are suitable for wet magnetic separation of materials with a particle size of less than 3mm, such as magnetite, pyrrhotite, roasted ore, ilmenite, etc. They 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 machines in the industry.

[0003] In the prior art, a collection box is placed directly at the bottom discharge port of the magnetic separator. Since it collects non-magnetic materials, when collecting powder materials, a large amount of dust will be dispersed in the air during the process of the powder materials falling from the magnetic separator to the collection box, which reduces the quality of the working environment and is not conducive to the health of the workers. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, the utility model provides a magnetic separator unloading device.

[0005] A magnetic separator unloading device includes a material collection box provided below the discharge port of the magnetic separator, a conveying mechanism provided below the material collection box, the conveying mechanism including a plurality of equally spaced conveyor belts installed on a conveying frame, a plurality of support columns provided below the material collection box and staggered with the conveyor belts, the support columns being installed on a base plate, a weighing device provided at the bottom of the base plate, and a driving mechanism provided at the bottom of the weighing device for driving it to perform reciprocating lifting motion.

[0006] Furthermore, the driving mechanism includes a lifting cylinder installed on the conveying frame, the output end of the lifting cylinder is connected to the support frame, and the weighing device is installed on the support frame.

[0007] Further, a limiting protrusion is provided on the inner side wall of the discharge port of the magnetic separator, and the inner side wall of the limiting protrusion is an inclined surface.

[0008] Further, an iron ore collection box is provided below the iron ore outlet of the magnetic separator.

[0009] Further, fixing frames are provided on both sides of the conveying frame, and a number of guide rods are provided on the fixing frames.

[0010] Due to the adoption of the above technical solutions, the beneficial technical effects of the present utility model are as follows: When the material collection box is conveyed to the lower part of the discharge port of the magnetic separator through the conveyor belt in the present utility model, the support columns rise to lift the material collection box, so that the upper part of the material collection box is inserted into the feeding port of the magnetic separator, effectively reducing the dust diffused in the air during the material feeding process. When the weighing device detects that the collection box reaches the specified weight, the feeding mechanism at the feeding port of the magnetic separator stops feeding and waits for a certain period of time. After all the materials in the magnetic separator have fallen into the material collection box, the support columns descend, and the material collection box is placed back on the conveyor belt again. The material collection box is conveyed to the next working position through the conveyor belt, thereby completing the material feeding. The feeding method is simple and effectively reduces the dust in the air. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to more clearly illustrate the technical solutions of the present utility model, the present utility model will be further described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only one embodiment of the present utility model. For those of ordinary skill in the art, without creative efforts, other embodiments obtained based on this drawing and embodiment all fall within the protection scope of the present utility model.

[0016] According to Figures 1-3As shown in the figure, a discharging device of a magnetic separator 1 includes a material collection box 2 provided below the discharge port of the magnetic separator 1. A conveying mechanism is provided below the material collection box 2. The conveying mechanism includes a number of conveyor belts 4 arranged at equal intervals and installed on a conveying frame 3. A number of support columns 5 are provided below the material collection box 2 and are distributed alternately with the conveyor belts 4. The support columns 5 are installed on a bottom plate 6. A weighing device 7 is provided at the bottom of the bottom plate 6, and a driving mechanism for driving it to perform reciprocating lifting motion is equipped at the bottom of the weighing device 7.

[0017] In the above specific technical solution, when the material collection box 2 is conveyed to below the discharge port of the magnetic separator 1 through the conveyor belt 4, the support column 5 rises to lift the material collection box 2, so that the upper part of the material collection box 2 is inserted into the feeding port of the magnetic separator 1, effectively reducing the dust diffused in the air during the process of material discharging. When the weighing device 7 detects that the collection box reaches the specified weight, the feeding mechanism at the feeding port of the magnetic separator 1 stops feeding, and waits for a certain period of time. After all the materials in the magnetic separator 1 have fallen into the material collection box 2, the support column 5 descends, and the material collection box 2 is placed back on the conveyor belt 4 again. The material collection box 2 is conveyed to the next working position through the conveyor belt 4, thus completing the discharging of the material. The discharging method is simple and effectively reduces the dust in the air.

[0018] The driving mechanism includes a lifting cylinder 8 installed on the conveying frame 3. The output end of the lifting cylinder 8 is connected to a support frame 9, and the weighing device 7 is installed on the support frame 9.

[0019] On the inner side wall of the discharge port of the magnetic separator 1, a limiting protrusion 10 is provided. The inner side wall of the limiting protrusion 10 is an inclined surface. When the upper end surface of the material collection box 2 contacts the limiting protrusion 10, the material collection box 2 stops moving, and the limiting protrusion 10 can also play a sealing role.

[0020] Below the iron ore outlet of the magnetic separator 1, an iron ore collection box 11 is provided.

[0021] On both sides of the conveying frame 3, fixed frames 12 are provided, and a number of guide rollers 13 are provided on the fixed frames 12, which is beneficial to ensuring the connection between the material collection box 2 and the discharge port of the magnetic separator 1.

[0022] It should be noted that a centering device is also provided at the front end of the conveying frame 3 to ensure that the material collection box 2 is located in the middle of the conveyor belt 4, and then is guided and conveyed to directly below the discharge port of the magnetic separator 1 through the guide rollers 13. In addition, a sensor is provided on the conveying frame 3. When the sensor detects that the material collection box 2 is located at the specified position, a signal is sent out, and the lifting cylinder 8 is started to drive the material collection box 2 to rise.
