Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separation devices, in particular to a linear magnetic separation device. Background Art

[0002] Magnetic separators are widely used in many industrial fields, mainly for separating materials with different magnetic properties. For linear magnetic separators with conveyors, refer to Figure 1 The material is transported backward on the material conveyor belt below, and the magnetic separation conveyor belt is located above the material conveyor belt, and the lower belt part of the magnetic separation conveyor belt and the upper belt part of the material conveyor belt move in the same direction at the same speed or at a differential speed. As the material is transported, the magnetic material will be adsorbed on the magnetic separation conveyor belt. Figure 1 This type of conveying magnetic separation method has the following problems. Since the magnetic separation conveyor belt and the adjacent side of the material conveyor belt move in the same direction, the closer the lower belt of the magnetic separation conveyor belt is to the rear section, the more magnetic substances are adsorbed on it. The more magnetic substances are adsorbed, the worse the magnetic attraction effect at the corresponding position will be. Figure 1 As shown, due to the accumulation of a large amount of magnetic material in the second half of the magnetic separation conveyor belt, the magnetic attraction effect in the second half is greatly reduced, resulting in poor magnetic separation effect of the material.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] Reference Figure 2 A linear magnetic separation device includes a material conveyor 1 and a magnetic material conveyor 17. Both conveyors are operated by a motor-driven supporting roller. The material conveyor 1 includes a first endless conveyor belt 2, which includes a material upper conveyor belt portion 7. The magnetic material conveyor 17 includes a second endless conveyor belt 12, which includes a horizontal belt portion 19 parallel to the material upper conveyor belt portion 7. The magnetic material conveyor 17 includes a third magnetic attraction member 18 located on the inner side of the horizontal belt portion 19. The magnetic force of the third magnetic attraction member 18 can penetrate the horizontal belt portion 19 to magnetically attract the ferromagnetic material on the material upper conveyor belt portion 7. The movement direction of the horizontal belt portion 19 is opposite to the movement direction of the material upper conveyor belt portion 7.

[0017] refer to Figure 2 When the device is working, the material is placed upstream of the upper conveyor belt 7. During the material conveying process, the third magnetic element 18 attracts the ferromagnetic substances mixed in the material upward by magnetic attraction. Since the horizontal belt 19 is arranged below the third magnetic element 18, the ferromagnetic substances are adsorbed on the bottom surface of the horizontal belt 19. The movement direction of the horizontal belt 19 of the device is opposite to the movement direction of the upper conveyor belt 7 of the material, that is, the upper conveyor belt 7 of the material is conveyed to the right, and the horizontal belt 19 is conveyed to the left. This working mode has the following advantages: since the horizontal belt 19 is on the right The end has just entered the magnetic attraction part, so the right end of the horizontal belt portion 19 is relatively clean, and the distribution of ferromagnetic materials adsorbed below the horizontal belt portion 19 gradually increases from right to left. Therefore, the magnetic attraction effect of the right end of the horizontal belt portion 19 is stronger than that of the left end. Due to the magnetic attraction of the magnetic conveyor 17, the ferromagnetic materials on the conveyor belt portion 7 on the material gradually decrease from left to right. Therefore, the end of the conveyor belt portion 7 on the material with less ferromagnetic materials corresponds to the end of the magnetic conveyor 17 with stronger suction. Therefore, when the material moves to the end, it can be more thoroughly magnetically separated and impurities removed.

[0018] During magnetic separation, part of the material will be adsorbed on the ferromagnetic material, causing part of the material to be adsorbed on the second circular conveyor belt 12 together with the ferromagnetic material. The second circular conveyor belt 12 includes a vertical belt portion 9, and the vertical belt portion 9 is connected to the downstream of the horizontal belt portion 19. The magnetic material conveyor 17 includes a first magnetic attraction component 8 located on the inner side of the vertical belt portion 9. The first magnetic attraction component 8 and the third magnetic attraction component 18 are continuously arranged. A vibration roller group 11 is provided on the inner side of the vertical belt portion 9. The vibration roller group 11 can make the vertical belt portion 9 vibrate continuously in the horizontal plane.

[0019] The ferromagnetic material transitions from the horizontal belt portion 19 to the vertical belt portion 9 in a vertical state, and the vertical belt portion 9 is provided with a vibrating roller group 11 that can make the vertical belt portion 9 vibrate continuously in the horizontal plane. The separation of the ferromagnetic material and the material is achieved through the vibration of the vertical belt portion 9. Since the vertical belt portion 9 is vertically arranged, part of the ferromagnetic material may also be shaken off during the shaking of the vertical belt portion 9. In the process of the ferromagnetic material falling downward, it will be re-adsorbed by the first magnetic suction component 8 on the surface of the vertical belt portion 9. Through this implementation method, the loss of material can be reduced.

[0020] The vibration roller group 11 only needs to be able to achieve a small amplitude vibration of the vertical belt portion 9. For example, a supporting roller is set, and multiple round rollers are rotatably connected on the supporting roller, and the round rollers are supported on the back of the vertical belt portion 9. Since there is ferromagnetic material in front of the vertical belt portion 9, the vertical belt portion 9 will be squeezed against the round roller. The supporting roller is vibrated by a vibration motor, and the vibrating supporting roller is used to vibrate multiple round rollers, and the vertical belt portion 9 is driven to vibrate through the round roller.

[0021] As an embodiment, the second circular conveyor belt 12 includes a first bend portion 16 and a second bend portion 20, the first bend portion 16 is connected to the downstream of the vertical belt portion 9, the magnetic material conveyor 17 includes a second magnetic member 10 located at the upstream end of the inner side of the first bend portion 16, the second magnetic member 10 and the first magnetic member 8 are continuously arranged, the second bend portion 20 is connected between the downstream of the first bend portion 16 and the upstream of the horizontal belt portion 19, and a magnetic material receiving container 21 is provided at the corner position of the first bend portion 16 and the second bend portion 20. When the ferromagnetic material moves to a position where there is no second magnetic member 10, the magnetic force disappears, and the ferromagnetic material finally follows the second circular conveyor belt 12 to move to the first bend portion 16 and falls into the magnetic material receiving container 21, completing the separation of the ferromagnetic material and the second circular conveyor belt 12.

[0022] Due to the effect of magnetic force, the ferromagnetic material will drive the horizontal belt portion 19 to approach the third magnetic component 18. In order to prevent the horizontal belt portion 19 from being squeezed, the magnetic material conveyor 17 includes a support roller group 15, which is arranged between the horizontal belt portion 19 and the third magnetic component 18, and supports the back side of the horizontal belt portion 19 through the support roller group 15.

[0023] The material conveyor 1 includes a vibration component arranged below the conveyor belt portion 7 on the material, and the vibration component includes a support plate 5 arranged parallel to the conveyor belt portion 7 on the material, and an elastic support leg 3 capable of vertical extension and contraction is installed between the bottom of the support plate 5 and the frame of the material conveyor 1, and a vibration motor 6 is installed at the bottom of the support plate 5. A plurality of thrust springs 4 are installed at intervals on the top surface of the support plate 5, and the top end of the thrust spring 4 abuts against the bottom surface of the conveyor belt portion 7 on the material. The support plate 5 is driven to vibrate by the vibration motor 6, and the thrust spring 4 is driven by the support plate 5 to push the conveyor belt portion 7 on the material to vibrate, so that the material can be better separated from the ferromagnetic material.

[0024] The first magnetic attraction component 8 , the second magnetic attraction component 10 , and the third magnetic attraction component 18 are all electromagnets.

[0025] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technical solution, concept, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
