Description

Technical Field

[0001] The present application relates to the technical field of mineral processing, and in particular to a device for automatically separating metal impurities from magnetite. Background Art

[0002] At present, iron removal in the mineral processing process can be said to be a major problem in the industry, and some mineral processing plants have also made some attempts. There are many ways to remove iron in the mineral processing process, and there are two common ones: one is to set up a metal detector, which is linked with the belt. After the metal detector detects metal, the belt stops, and the post worker set up next to the belt picks out the iron, and then the post worker contacts the centralized control operator to resume the belt operation. Although this method has a good iron removal effect, the shutdown will seriously affect the output and requires full-time personnel to complete it; the other is to set up an iron remover above the belt. Since the material of the iron remover is an electromagnet or a permanent magnet, this method can only remove magnetic iron, but not non-magnetic metals, and the post needs to regularly clean up the scrap iron adsorbed on the iron remover. This method cannot remove non-magnetic metals, and the sense of responsibility of the post affects the iron removal effect of magnetic iron. With the large-scale equipment, relying on manual iron picking by stopping the machine has problems such as high labor intensity, missed picking, and reduced processing volume. Relying on the iron remover to remove iron cannot remove non-magnetic metals, and requires high professional quality of the post.

[0003] In summary, the industry urgently needs to invent an automatic iron removal system that can remove metal debris in the ore dressing process to protect crushers, high-pressure rollers and other equipment. This process cannot affect the output and can be completed automatically without human intervention. Therefore, we proposed an automatic separation device and method for magnetite metal impurities.

[0041] like Figure 3 As shown: a metal detector 6 is provided on the left side of the second conveying device, and the second conveying device is inserted in the middle of the metal detector 6.

[0042] Specifically: the metal detector 6 adopts the existing equipment on the market.

[0043] like Figure 3 As shown: the upper and lower sides of the right end of the separator 9 are fixedly connected with the first outlet and the second outlet respectively, and the middle of the left end of the first outlet and the second outlet is connected with a connecting shaft through a bearing, and the left end of the connecting shaft is fixedly connected with a partition 10, and the front end of the connecting shaft is fixedly connected with a flap driving device 8.

[0044] Specifically, the flap driving device 8 can rotate in the inner cavity of the separator 9, so as to divide the separator 9 into two channels.

[0045] like Figure 1 and Figure 4 As shown: the flap drive device 8 includes a second worm gear reducer 8-1, a second rotating rod 8-2, a third limit switch 8-3, a second positioning rod 8-4, a fourth limit switch 8-5 and a second motor 8-6, the second motor 8-6 is fixedly connected to the motor bracket, and the rotating shaft of the second motor 8-6 is connected to the input shaft of the second worm gear reducer 8-1, and the output shaft of the second worm gear reducer 8-1 is connected to the second rotating rod 8-2, and the second rotating rod 8-2 is connected to the rotating rod of the bracket.

[0046] The third limit switch 8-3 and the fourth limit switch 8-5 are fixedly connected to the rear side and the right side of the upper end of the second worm gear reducer 8-1, respectively. A second positioning rod 8-4 is provided on the outer side of the second rotating rod 8-2, and the second positioning rod 8-4 is located between the third limit switch 8-3 and the fourth limit switch 8-5.

[0048] like Figure 1 and Figure 3 As shown: the upper and lower parts of the right end of the separator 9 are respectively fixedly connected with two outlets, and the two outlets are respectively connected with the upper and lower sides of the partition 10, and the lower parts of the two outlets are respectively provided with a second conveyor belt 1-3 and a third conveyor belt 1-2.

[0049] Specifically, the second conveyor belt 1-3 and the third conveyor belt 1-2 are both prior art and are existing equipment on the market.

[0050] When the equipment is working, the first conveyor belt 1-1 conveys the initial ore. If the ore contains magnetic iron pieces, they will be adsorbed when passing through the adsorption area of ​​the electromagnetic iron remover 3. This cycle will continue. When the iron pieces adsorbed by the electromagnetic iron remover 3 reach the limit (too much adsorption and no more adsorption), the rotating device 4 will drive the bracket to rotate, so that the electromagnetic iron remover 3 rotates to the top of the scrap iron collection box 5 to release the iron pieces, and then returns to the original position after release.

[0051] The adsorption limit of the electromagnetic iron remover 3 is judged. The amount of iron adsorbed by the electromagnetic iron remover 3 is detected by the first weighing sensor 2-1 and the second weighing sensor 2-2. When the weight is greater than or equal to a certain value, it is considered that the adsorption limit is reached. The weight signal is connected to the peripheral PLC controller for judgment.

[0052] The second conveyor can remove non-magnetic metal pieces mixed in the ore. The magnetic roller 7 has a certain adsorption effect on the magnetic ore, so the movement trajectories of the non-magnetic metal pieces and the magnetic ore are different. By changing the position of the partition 10, the purpose of separating the non-magnetic metal and the magnetic ore is achieved. When there is no non-magnetic metal, the partition 10 is close to the lower end surface of the separator 9, and all the ore is discharged from the upper outlet of the right end of the separator 9. When non-magnetic metal pieces are mixed in the ore, the metal detector 6 sends a signal to the PLC control system, and then the PLC control system sends an instruction to control the flap drive device 8 to rotate the partition 10 to the specified position, and the magnetic ore and the non-magnetic metal pieces are separated by the action of the magnetic roller 7. After the magnetic ore is adsorbed by the magnetic roller 7, the running trajectory will be biased downward, so that the magnetic ore and the non-magnetic metal pieces pass through the partition 10 in the middle of the separator 9 and enter different outlets, and fall on the second conveyor belt 1-3 and the third conveyor belt 1-2 for transportation, that is, the non-magnetic metal pieces enter the non-magnetic metal collection box, and the magnetic ore enters the next process.

[0053] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. It will be apparent to those skilled in the art that various modifications to these embodiments are possible, and the general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest scope consistent with the principles and novel features applied for by the present application.
