Description

TECHNICAL FIELD

[0001] The present application relates to the field of waste, household garbage, industrial solid waste sorting, in particular to a magnetic separation equipment with anti-blocking function. BACKGROUND

[0002] With the rapid development of society, resources are constantly decreasing due to the continuous increase of waste, so it is necessary to recover useful substances and energy from waste by engineering technology to ensure resource recycling.

[0003] At present, waste containing metal and non-metal (with winding characteristics) generally needs to be separated by the magnetic separation device of the magnetic separation equipment in the recycling process to separate the metal and non-metal (with winding characteristics) in the waste. The existing magnetic separation equipment device includes a magnetic separation device, and the magnetic separation device includes a magnetic separation hopper, a conveying line and a magnetic separation roller. The opposite sides and the bottom of the hopper are open structures. The openings on the opposite sides of the hopper are the inlet and outlet, respectively. The opening at the bottom of the hopper is the discharge port. The discharge port is isolated from the inlet and outlet by a partition. The inlet is connected to the discharge end of the conveying line. The magnetic separation roller is rotatably arranged on the hopper and drivingly connected to the end of the conveying belt of the conveying line, so that the magnetic separation roller rotates with the transmission of the conveying belt. When the waste is conveyed from the beginning to the end of the conveying belt, i.e. the position of the magnetic separation roller, the metal in the waste will be attracted by the magnetic separation roller and be attracted by the magnetic separation roller. The non-metallic material is discharged from the outlet. Since the conveying belt is in a circulating transmission state, when the metal attracted by the magnetic separation roller is conveyed to the lower part and has no magnetic induction with the magnetic separation roller, it will be separated from the conveying belt and fall from the position of the discharge port, realizing the separation of metal and non-metal in the waste.

[0004] However, in the process of separating the metal and non-metal in the waste, some non-metallic materials with winding characteristics may be hung on the partition during the discharge process from the discharge port, or some non-metallic materials with winding characteristics may be pressed by the metal, causing these pressed non-metallic materials with winding characteristics to enter the lower part of the conveying belt with the metal. Thus, these non-metallic materials with winding characteristics will often be hung on the partition and block the discharge port of the metal during the falling process of the metal, which requires manual intervention to ensure the normal operation of the magnetic separation device.

[0034] Please refer to Figures 1-3The application shows a magnetic separation device with anti-blocking function, comprising a magnetic separation device and a screening device; the magnetic separation device comprises a first conveying line 10, a hopper 20, a magnetic separation cylinder 30, a sorting cylinder 40 and a driving device, the first conveying line 10 is used for conveying waste (such as waste containing steel wires); specifically, the first conveying line 10 comprises a rack 101, a power unit and a conveying belt 102, the conveying belt 102 is drivingly arranged on the rack 101, and the waste containing metal objects and non-metal objects with winding characteristics is conveyed on the conveying belt 102; the power unit is arranged on the rack 101 and drivingly connected with the conveying belt 102, and the power unit is used for driving the conveying belt 102 to drive; the material falling port 203 is between the material inlet 201 and the material outlet 202, and the material inlet 201 and the material outlet 202 are isolated from the material falling port 203 by a partition plate; the hopper 20 is connected with the end of the first conveying line for conveying materials through the material inlet 201, that is, the hopper 20 is connected with the rack 101 and the end of the conveying belt 102 is connected with the material inlet 201; the magnetic separation cylinder 30 is rotatably arranged in the hopper 20 or on the rack 101 of the first conveying line 10 and located at the end of the conveying belt 102, the magnetic separation cylinder 30 is a power cylinder for driving the conveying belt 102 to drive, and the magnetic separation cylinder is used for magnetically separating the metal objects and the non-metal objects in the waste and making the separated metal objects and non-metal objects fall from the material falling port 203 and be discharged from the material outlet 202 respectively; the sorting cylinder 40 is rotatably arranged in the hopper 20, and the sorting cylinder 40 is used for cleaning the non-metal objects with winding characteristics hung on the partition plate; the driving device is arranged on the hopper 20 or the rack 101 of the first conveying line 10, and the driving device is used for driving the rotation of the sorting cylinder 40.

[0035] In the embodiment, the screening device 50 comprises a support frame 502, a rotating cylinder 501 and a driving structure 503, the rotating cylinder 501 is rotatably arranged on the support frame 502 and connected with the material outlet 202, the rotation axis of the rotating cylinder 501 is coaxial with the central axis of the material outlet, the driving structure 503 is arranged on the support frame 502 and used for driving the rotation of the rotating cylinder 501, and a screening part is arranged on the bottom of the outer wall of the rotating cylinder 501 and communicated with the inner cavity of the rotating cylinder 501, the screening part is used for screening the iron particles mixed in the non-metal objects entering the rotating cylinder 501.

[0036] In use, the waste containing metal objects and non-metal objects with winding characteristics is fed from the feeding port 105 of the first conveying line 10 and conveyed on the conveying belt 102, the power of the conveying belt 102 is from the power unit, when the waste is conveyed to the end of the conveying belt 102, the metal objects in the waste are magnetically induced by the magnetic separation drum 30 and are attracted by the magnetic separation drum 30, and the non-metal objects enter the rotating drum 501 from the discharge port 202, since the conveying belt 102 is in a circulating transmission state, when the metal objects attracted by the magnetic separation drum 30 are conveyed to the lower part and are not magnetically induced by the magnetic separation drum 30, the metal objects are separated from the conveying belt 102 and fall from the position of the discharging port 203, so that the metal and non-metal in the waste are separated; in the process of waste separation, when the non-metal objects with winding characteristics hang on the partition plate, the sorting drum 40 rotates under the driving of the driving device to send the non-metal objects with winding characteristics hanging on the partition plate out of the discharging port 203, so as to avoid that the non-metal objects with winding characteristics hang on the partition plate and block the discharging port 203 of the metal objects, thereby ensuring the normal operation of the magnetic separation device without manual intervention, and the non-metal materials entering the rotating drum 501 from the discharge port 202 are turned over with the rotation of the rotating drum 501, so that the iron particles mixed in the non-metal materials in the rotating drum 501 are screened out by the screening part and removed, thereby ensuring the purity of the non-metal materials.

[0037] On the basis of the above structure, the application further comprises a second conveying line 60, which is used for outputting the metal objects falling from the discharging port 203; in addition, the second conveying line 60 is located at the bottom of the rotating drum 501, that is, the screening part makes the inner cavity of the rotating drum 501 communicate with the second conveying line 60, so that the iron particles mixed in the non-metal objects in the rotating drum 501 fall into the second conveying line 60 from the screening part and are output by the second conveying line 60 during the turning over process of the non-metal objects entering the rotating drum 501 with the rotation of the rotating drum 501. It can be known that the second conveying line 60 of the embodiment also has the function of receiving the iron particles screened out by the screening part.

[0038] In the embodiment, the screening part is a plurality of through holes 5011 opened on the outer bottom wall of the rotating drum 501, so that the iron particles mixed in the non-metal objects in the rotating drum 501 fall into the second conveying line 60 from the through holes 5011.

[0039] It should be noted that the driving connection between the rotating drum 501 and the driving structure 503 is a relatively conventional mechanical transmission structure, so it will not be described here; in addition, the structure of the second conveying line 60 is a relatively mature technology in mechanical transmission, which will not be described here.

[0040] Please refer to Figure 2 , Figure 4 andFigure 6 The magnetic separation roller 30 is located above the material falling port 203, and the downward projection of the side of the magnetic separation roller 30 close to the material inlet 201 falls within the material falling port 203. In this way, under the magnetic separation of the magnetic separation roller 30, the metal in the waste will fall from the material falling port 203 into the second conveying line, and the non-metal will enter the rotary drum from the material outlet 202.

[0041] In the embodiment, the magnetic separation device of the present application further comprises a magnetic separator 11 for preliminarily separating the metal in the waste conveyed on the first conveying line 10. That is, it can be understood that when the waste is fed from the feeding port 105 onto the conveying belt 102 on the first conveying line 10 and conveyed to the hopper 20 by the conveying belt 102, the waste on the conveying belt 102 is preliminarily separated from the metal by the magnetic separator 11, and then further separated by the magnetic separation device, thereby improving the magnetic separation effect of the magnetic separation device of the present application.

[0042] In the embodiment, a notch 1011 is formed on the upper surface of the frame 101, which communicates with the conveying belt 102 of the first conveying line 10. Of course, the magnetic separation component of the magnetic separator 11 is located at the position of the notch 1011, so that the magnetic separator 11 can separate the metal in the waste conveyed on the conveying belt 102 of the first conveying line 10.

[0043] It should be noted that the magnetic separator 11 is suitable for separating substances with magnetic differences, and is widely used in mining, timber industry, kiln industry, chemical industry, food industry and other industries, and belongs to the existing mature technology, so the structure and working principle thereof will not be described here.

[0044] In the embodiment, the power unit comprises a driving unit, a driving roller and a driven roller 103. The driving roller and the driven roller 103 are rotatably arranged on the frame 101, and the opposite ends of the conveying belt 102 are drivingly sleeved on the driving roller and the driven roller 103, respectively. The driving unit is drivingly connected with the driving roller. In this way, the conveying belt 102 can be circularly driven between the driving roller and the driven roller 103 under the action of the driving unit driving the driving roller.

[0045] In the embodiment, the conveying belt 102 is arranged obliquely from bottom to top, and specifically, the angle between the conveying belt 102 and the horizontal ground is 45°, but is not limited to 45°. After the feeding port 201 on the hopper 20 is connected to the rack 101, it is ensured that the end surface of the discharging port 202 on the hopper 20 is perpendicular to the horizontal ground, so that the separation effect of the waste can be better achieved. Of course, after the feeding port 201 is connected to the rack 101, and in order to ensure that the end surface of the discharging port 202 on the hopper 20 is perpendicular to the horizontal ground, the feeding port 201 on the hopper 20 is in a “V” shape.

[0046] In the embodiment, the magnetic separation drum 30 is one of the driving drum and the driven drum 103, the magnetic separation drum 30 is rotatably arranged on the rack 101, and the magnetic separation drum 30 is a driving drum, that is, the driving drum is arranged at the end of the conveying belt 102, so that the rotation force of the magnetic separation drum 30 is larger.

[0047] Of course, in other embodiments, the magnetic separation drum 30 can also be the driven drum 103, and if the magnetic separation drum 30 is the driven drum 103, the driven drum 103 is arranged at the end of the conveying belt 102, which is not limited here.

[0048] In the embodiment, the driving unit is used as the driving device, and for this purpose, the sorting drum 40 and the magnetic separation drum 30 are drivingly connected; the driving unit of the embodiment is a driving motor 104 drivingly connected with the magnetic separation drum 30. Therefore, the power for driving the magnetic separation drum 30 and the power for driving the sorting drum 40 are the same, so that a power structure can be saved, and the effect of saving cost is achieved.

[0049] It is worth noting that since the magnetic separation drum 30 and the sorting drum 40 share one power structure, the magnetic separation drum 30 and the sorting drum 40 rotate synchronously and in the same direction, so that the sorting drum 40 can transport the non-metallic objects with winding characteristics hanging on the partition plate to the discharging port 202, avoiding the non-metallic objects with winding characteristics hanging on the partition plate from falling from the position of the discharging port 203, and further improving the separation effect of the anti-blocking magnetic separation device.

[0050] In the embodiment, the linear speeds of the magnetic separation drum 30 and the sorting drum 40 can be set to be consistent or inconsistent, and the specific conditions are reasonably selected and changed by the inventor according to the actual use conditions; since the magnetic separation drum 30 and the sorting drum 40 share one power structure, the linear speeds of the magnetic separation drum 30 and the sorting drum 40 can be controlled by setting different diameters of the magnetic separation drum 30 and the sorting drum 40.

[0051] In the embodiment, the partition plate between the discharge port 202 and the dropping port 203 is the first partition plate 21, and the hopper 20 is further provided with an anti-winding member 24 for preventing the non-metallic objects with winding characteristics in the waste from being hung on the first partition plate 21. In this way, the non-metallic objects with winding characteristics can be further prevented from being blocked on the dropping port 203.

[0052] In the embodiment, the anti-winding member 24 includes a first connecting strip 241 and a second connecting strip 242. The opposite ends of the first connecting strip 241 are connected with the first partition plate 21 and the second connecting strip 242 respectively and are arranged along the length direction of the sorting drum 40. The second connecting strip 242 is arranged upwardly and obliquely from the first connecting strip 241 to the sorting drum 40. In this way, the non-metallic objects with winding characteristics can be effectively prevented from being accumulated on the anti-winding member 24. The spacing between the second connecting strip 242 and the sorting drum 40 in the embodiment is D1, which should satisfy the relationship of 0 < D1 < 0.2 mm. In the embodiment, D1 is set to be 0.1 mm. In this way, the non-metallic objects with winding characteristics can be prevented from being hung between the anti-winding member 24 and the sorting drum 40, and the first partition plate 21. The value of D1 of 0.1 mm can make the second connecting strip 242 not affect the rotation effect of the sorting drum 40 to be optimal. In other embodiments, D1 can also be set to be 0.099 mm or 0.19 mm, which is not limited herein.

[0053] In the embodiment, the partition plate between the discharge port 202 and the dropping port 203 is the first partition plate 21, and the hopper 20 is further provided with an anti-winding member 24 for preventing the non-metallic objects with winding characteristics in the waste from being hung on the first partition plate 21. In this way, the non-metallic objects with winding characteristics can be further prevented from being blocked on the dropping port 203.

[0054] In the embodiment, the spacing between the third partition plate 23 and the conveying belt 102 is D2, which should satisfy the relationship of 0 < D2 < 0.3 m. In the embodiment, D2 is set to be 0.15 mm. In this way, the non-metallic objects with winding characteristics can be prevented from being hung between the third partition plate 23 and the conveying belt 102, and the second partition plate 22. The value of D2 of 0.15 mm can make the third partition plate 23 not affect the transmission effect of the conveying belt 102 to be optimal. In other embodiments, D2 can also be set to be 0.099 mm or 0.299 mm, which is not limited herein. In the embodiment, the third partition plate 23 and the second partition plate 22 can be detachably connected. In this way, the spacing between the second partition plate 22 and the conveying belt 102 can be conveniently adjusted.

[0055] The above embodiments are only the preferred embodiments of the present application, and cannot be used to limit the protection scope of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the protection scope of the present application.
