Description

Technical Field

[0001] This invention relates to the technical field of iron separation from materials, specifically a drum magnetic separation iron removal device suitable for cylindrical belt conveyors. Background Technology

[0002] Belt conveyors, also known as rubber belt conveyors, are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, and food for the assembly, testing, debugging, packaging, and transportation of objects. Belt conveyors are friction-driven machines that transport materials continuously.

[0003] Magnetic separators are among the most widely used and versatile machines in industry. They are suitable for separating substances with magnetic differences and are widely used in industries such as mining, timber, kilns, chemicals, and food.

[0004] In the process of conveying crushed non-metallic mineral materials using belt conveyors, it is usually necessary to add an iron removal device to remove and separate iron-containing impurities in the non-metallic minerals. However, during the material conveying process, due to the excessive accumulation of materials on the conveyor, when the magnetic separation drum comes into contact with the material, it can only remove iron-containing impurities from the top surface of the material. Moreover, it is difficult to completely remove iron-containing impurities inside the material with a single magnetic separation, requiring multiple operations by personnel. The iron removal efficiency is low, which affects the subsequent processing and production of materials. Therefore, in order to address the above shortcomings, the present invention makes the following improvements. Summary of the Invention

This device solves the problem that when materials accumulate on the conveyor and become too concentrated, the magnetic separation drum can only remove iron-containing impurities from the top surface of the material when it comes into contact with the material, making it difficult to completely remove iron-containing impurities from the inside of the material, thus resulting in low iron removal efficiency.

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5 and Figure 6As shown, this invention provides a drum magnetic separation iron removal device suitable for cylindrical belt conveyors, including a base plate and a frame 1 fixedly connected to the top of the base plate via support legs. A collection frame 5 is movably connected to one side of the top of the base plate to collect materials. A conveyor belt is internally driven in the frame 1. A pre-iron removal mechanism is provided on the top of the frame 1, and the pre-iron removal mechanism includes a leveling and crushing component 2 and an agitating iron removal component 3. The agitating iron removal component 3 includes a first motor 31. A support plate is fixedly connected to the front of the frame 1. The bottom of the first motor 31 is slidably connected to the top of the support plate via a protrusion. A through groove 32 is opened on the top of the frame 1, and a toothed plate 33 is movably connected inside the through groove 32. One end of the output shaft of the first motor 31 is fixedly connected to a rotating rod 34 via a coupling. A gear 35 that meshes with the toothed plate 33 is fixedly connected to the surface of the rotating rod 34. A support ring 36 is fixedly connected to one end of the rotating rod 34, and the surface of the support ring 36 is fixedly connected to... A magnet 37 is provided. A sliding plate 38 is slidably connected to the back of the frame 1 via a fixed plate. A rotating ring 39 is rotatably provided on the front of the sliding plate 38. One end of the magnet 37 is fixedly connected to the surface of the rotating ring 39. A vibrating rod 310 is fixedly connected to the front of the sliding plate 38 and inside the rotating ring 39. A third electric push rod 311 is fixedly connected to both sides of the bottom of the inner wall of the through groove 32. The protruding end of the third electric push rod 311 is connected to the bottom of the toothed plate 33 via a mounting plate 314. The sliding plate 38 is fixedly connected to an L-shaped plate 312 on its back side, and a first electric push rod 313 is fixedly connected to the top of the L-shaped plate 312. The top of the sliding plate 38 has an insertion hole. The flattening and crushing mechanism 2 includes a U-shaped support frame 21 fixedly connected to one side of the top of the frame 1, and a second electric push rod 22 is fixedly connected to the top of the U-shaped support frame 21. The extended end of the second electric push rod 22 is fixedly connected to a flattening plate 23, and a crushing head is fixedly connected to the bottom of the flattening plate 23.

[0030] With the above structure, the material piled on top of the conveyor belt can be pushed downwards to flatten it and further crush it, exposing iron impurities and agitating and dispersing the material, increasing the gaps between the materials, so that the magnet 37 can penetrate deep into the material, improving the quality and efficiency of iron removal.

[0031] Example 2

[0032] Please see Figure 1 and Figure 4As shown, a secondary iron removal mechanism 4 is provided on the other side of the top of the frame 1. The secondary iron removal mechanism 4 includes upright plates 41 fixed to the front and back of the frame 1 respectively, and a magnetic separator 42 is rotatably connected between opposite sides of the two upright plates 41. A second motor 43 is fixedly connected to the surface of the upright plate 41 on the front side, and one end of the output shaft of the second motor 43 is fixedly connected to one end of the magnetic separator 42 through a coupling. A placement plate is fixedly connected between one side of the two upright plates 41, and a collection box 44 is movably connected to the top of the placement plate. 44 collects iron-containing impurities. A connecting plate 45 is fixedly connected to one side of the upright plate 41 on the front by a connecting rod. A scraper 46 is movably connected to the top of the connecting plate 45. The top of the scraper 46 contacts the surface of the magnetic separator drum 42. A T-shaped block 47 is fixedly connected to the bottom of the scraper 46. A T-shaped groove adapted to the T-shaped block 47 is opened on the top of the connecting plate 45, which can realize the replacement of the scraper 46 and avoid the problem of iron-containing impurities falling into the gap between the scraper 46 and the surface of the magnetic separator drum 42 due to wear.

[0033] With the above structure, residual iron-containing impurities in the material can be adsorbed, achieving complete removal of iron-containing impurities. It can also automatically clean the iron-containing impurities adsorbed on the surface of the magnetic separator 42 and collect them uniformly, reducing the labor required.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] The working principle of this invention is as follows: During use, the crushed non-metallic mineral material is discharged on top of the conveyor belt. The external switch is controlled to make the conveyor belt transport the material. When the material passes the U-shaped support frame 21, the second electric push rod 22 is activated, so that the extended end of the second electric push rod 22 drives the flat plate 23 to move downward. With the setting of the crushing head, the material can be pushed downward to flatten it, avoid accumulation, and can be crushed to a certain extent again, so that the iron impurities inside the material are exposed. The third electric push rod 311 is controlled to drive the toothed plate 33 to move downward through the mounting plate 314. At this time, the toothed plate 33 disengages from the gear 35, and the first motor 31 is activated, so that the first motor 31 drives the rotating rod 34 to rotate. Then the rotating rod 34 drives the magnet rod 37 to rotate through the support ring 36. At the same time, the vibrating rod 310 is activated. When the material passes the magnet rod 37, the rotation of the magnet rod 37 and the vibration of the vibrating rod 310 can disperse the material and increase the porosity of the material. The magnet rod 37 can insert into the material to adsorb the iron impurities inside.

[0036] After the iron is pre-removed by the magnet 37, the material is conveyed to the bottom of the surface of the magnetic separator 42. At this time, the second motor 43 is controlled to rotate, which drives the magnetic separator 42 to rotate. The magnetic separator 42 can further remove any iron-containing impurities that may remain in the material. As the magnetic separator 42 rotates, the material is scraped up by the scraper 46 and demagnetized by the demagnetizer. The iron-containing impurities that have lost their magnetism fall into the collection box 44 through the scraper 46. After the iron-containing impurities inside the material are completely removed, the second motor 43 can be turned off. The material after the iron-containing impurities are removed falls into the collection frame 5 for statistical collection.

[0037] The first electric push rod 313 is controlled to extend upward from the insertion hole, thereby releasing the limit on the sliding plate 38. The third electric push rod 311 is controlled to drive the toothed plate 33 to rise upward, so that the toothed plate 33 and the gear 35 mesh with each other. Then the first motor 31 is started, so that the first motor 31 drives the rotating rod 34 to rotate to the right. While rotating, the first motor 31 can move to the right at the top of the support plate until the magnet rod 37 moves to the bottom of the surface of the magnetic separation drum 42. The magnet rod 37 is then controlled to rotate. At this time, the iron-containing impurities adsorbed on the surface of the magnet rod 37 are removed to the surface of the magnetic separation drum 42 and finally scraped by the scraper 46 into the collection box 44, thus completing the cleaning work on the surface of the magnet rod 37.

[0038] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
