Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, specifically to a stone iron removal device. Background Technology

[0002] Stone conveyor belts are mainly used to transport stones that have been initially crushed after mining, so that they can be further crushed or processed. Stones often contain iron materials, so iron removal devices are needed to remove the iron materials.

[0003] Existing iron separators include electromagnetic chucks (which use magnetization) and belt separators. Both have certain drawbacks. Electromagnetic chucks are more efficient at adsorbing iron impurities, but after adsorbing a certain amount of iron impurities, they need to be stopped frequently to release the magnetism and remove the impurities. Belt separators have the disadvantage that when iron impurities are small, they are easily carried away by the stones and are not easily captured by the separator. Furthermore, both electromagnetic chucks and belt separators have requirements regarding the thickness of the transported stones. When the stone transport thickness is large, iron impurities are difficult to remove. Utility Model Content

[0007] To achieve the above objectives, the present invention provides the following technical solution: a stone iron removal device, including an iron removal box, an inlet on the top of the iron removal box, a side baffle fixedly installed inside the iron removal box near the inlet, a gate and a first cylinder movably installed on the side baffle, the first cylinder driving the gate to deflect.

[0008] A buffer assembly is installed below the gate.

[0015] (III) Beneficial Effects

[0016] This utility model provides a stone iron removal device. It has the following beneficial effects:

[0017] This stone iron removal device features a rotatable iron separator. When charged, the separator generates a magnetic effect, attracting iron impurities flowing through it. Once a certain amount is attracted, a gate and a flow-stopping plate block further stone flow at that location. Then, the electromagnetic chuck on that side rotates and demagnetizes, expelling the iron impurities. While the electromagnetic chuck is demagnetizing on that side, the stone can be transferred to the other side for transport, eliminating the need for machine downtime. Furthermore, the flow rate of the stone can be controlled via the gate and the tipping shaft, thereby controlling the thickness of the stone flowing through the electromagnetic chuck and ensuring uniform stone flow, thus improving iron removal efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-3 As shown, this utility model provides a technical solution: a stone iron removal device, including an iron removal box 1, the top of which is provided with a feed inlet 2, and a side baffle 3 is fixedly provided inside the iron removal box 1 near the feed inlet 2. A gate 4 and a first cylinder 5 are rotatably installed on the side baffle 3 respectively. The first cylinder 5 can drive the gate 4 to deflect. The opening size of the gate 4 on both sides can be controlled by the first cylinders 5 on both sides, thereby controlling the feeding speed.

[0024] A buffer assembly 6 is provided below the gate 4. The buffer assembly 6 includes an inverted V-shaped diversion platform 61. Stones flow down from both sides of the diversion platform 61. Multiple sets of springs 62 are installed on the top of the diversion platform 61. A buffer plate 63 is installed on the top of the springs 62.

[0025] Below the buffer assembly 6 is a magnetic separator 7, which includes a V-shaped guide plate 71. The guide plate 71 has slots 72 and a discharge port 73 on its two sides and in the middle, respectively. An electromagnetic chuck 74 with a charging and discharging magnetic function is rotatably installed in the slot 72 (the internal electromagnetic components are not shown, and the power line can be centrally located, which is known to be existing technology). The deflection angle of the electromagnetic chuck 74 is controlled at about 10 degrees. A flow-guiding side plate 75 is fixed at each of the four corners of the guide plate 71. The bottom of the magnetic separator 7 conveys the stone out of the magnetic separator box 1 through the guide pipe 8. A belt conveyor 12 is installed below the guide pipe 8.

[0026] The bottom of the diverter 61 is provided with an inclined second cylinder 13 on the left and right sides. The free end of the second cylinder 13 is equipped with a choke plate 14 that can contact the iron remover 7. After the choke plate 14 is fully extended, it does not affect the deflection of the electromagnetic chuck 74.

[0027] A rotatable tipping shaft 15 (driven by an external motor, not shown in the figure) is provided between the buffer assembly 6 and the iron remover 7. The tipping shaft 15 has multiple tipping blades. The stone falls onto the tipping blades and is transferred to the guide plate 71 as it rotates. Therefore, the feeding speed can be controlled by controlling the rotation speed of the tipping shaft 15.

[0028] The back of the iron remover 7 is provided with a guide plate 9, the bottom of the guide plate 9 is provided with a discharge port 10, and the bottom of the discharge port 10 is provided with a storage box 11.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] When in use, stones containing iron impurities enter the iron removal box 1 through the feed inlet 2, and are transported to the buffer plate 63 below by the gates 4 on both sides. The spring 62 at the bottom of the buffer plate 63 buffers and reduces the falling speed of the stones.

[0031] Afterwards, the stone falls from the buffer plate 63 onto the guide plate 71 below. The electromagnetic chuck 74 is powered on and magnetized to generate magnetic attraction (existing technology, not described in detail). It then adsorbs iron impurities in the stone. There is one electromagnetic chuck 74 on each side. When the iron impurities adsorbed by one of the electromagnetic chuck 74 accumulate to a certain amount, the electromagnetic chuck 74 is driven to flip by an external motor or a manual crank (not shown in the figure). Then the power is turned off, the electromagnetic chuck 74 loses its magnetism, the iron impurities are released, and the impurities fall through the guide plate 9 below and finally enter the storage box 11 through the discharge port 10 for temporary storage. The stone is finally discharged from the discharge port 73 and the guide pipe 8 and output through the belt conveyor 12.

[0032] It should be noted that before the electromagnetic chuck 74 flips, the first cylinder 5 on this side is first started to drive the gate 4 on this side to rotate, and the end of the gate 4 abuts against the buffer plate 63 to block the stone from continuing to flow down from this side. At the same time, the second cylinder 13 on this side is started to drive the intercepting plate 14 to extend and abut against the guide plate 71 to prevent the stone from entering the electromagnetic chuck 74. In order to avoid a complete shutdown, the stone continues to flow from the other side of the buffer plate 63, thereby ensuring that the iron removal process proceeds normally. By increasing the rotation speed of the turning shaft 15, the feeding speed of the stone can be controlled.

[0033] In summary, this stone iron removal device, by incorporating a rotatable iron separator, generates a magnetic effect after charging, thereby adsorbing iron impurities flowing through it. When the adsorbed amount reaches a certain level, the flow of stone at that location is blocked by a gate and a flow-stopping plate. Then, the electromagnetic chuck on that side rotates and demagnetizes, expelling the iron impurities. When the electromagnetic chuck demagnetizes at that location, the stone can be transferred to the other side for conveying, eliminating the need to stop the machine and wait. Furthermore, the flow rate of the stone can be controlled by the gate and the tipping shaft, thereby controlling the thickness of the stone flowing through the electromagnetic chuck, ensuring uniform stone flow, and thus improving iron removal efficiency.
