Description

Technical Field

[0001] This utility model relates to the field of TBM belt conveyor technology, and in particular to an intelligent iron removal device for the protection of TBM belt conveyors. Background Technology

[0002] In mineral processing, large ore blocks extracted from the mine need to undergo several stages of crushing: coarse, medium, and fine. Because mining is mechanized, iron impurities inevitably mix into the ore. These impurities are typically removed using belt conveyors. However, existing belt conveyors are generally installed above the belt conveyor and are primarily effective at removing iron filings. Larger objects, such as drill bits, shovel teeth, liners, wire ropes, and drill rods, can easily damage the iron removal components. Furthermore, when these larger objects are transferred to the next TBM belt conveyor, they can damage the conveyor belt below, as well as the crushing walls or roller surfaces of the mineral processing equipment. In severe cases, this can jam the equipment, causing production disruptions and frequently affecting its normal operation. This not only reduces production efficiency but also increases the workload for workers. Moreover, the damage caused by iron impurities significantly impacts the lifespan of the equipment, resulting in high maintenance costs. Therefore, a device is needed to remove iron impurities from ore to prevent these impurities from affecting the mineral processing equipment and thus improve production efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intelligent iron removal device for the protection of TBM belt conveyors. This iron removal device can intercept large-diameter iron foreign objects, preventing them from damaging the next conveyor belt or mineral processing equipment and affecting the transport and screening of ore.

[0004] To achieve the above objectives, this utility model provides an intelligent iron removal device for the protection of a TBM belt conveyor, including a belt conveyor, a metal detector installed above the belt conveyor, and an iron removal box located at the outlet end of the belt conveyor. The iron removal box has a feed inlet at its top and an interceptor frame at the feed inlet. The iron removal box contains multiple first electromagnetic adsorption plates and multiple second electromagnetic adsorption plates, which are staggered below the interceptor frame. The side of each of the multiple first electromagnetic adsorption plates furthest from the second electromagnetic adsorption plate is fixed to a first... On the connecting column, multiple second electromagnetic adsorption plates are fixed on the side away from the first electromagnetic adsorption plate. The upper and lower ends of the first and second connecting columns are fixed to the top and bottom plates of the iron removal box, respectively. Each electromagnetic adsorption plate is inclined, and the side of each electromagnetic adsorption plate adjacent to the connecting column it is higher than the side away from the connecting column. The bottom of the iron removal box is inclined, and a discharge port is provided on the side of the iron removal box, and the discharge port is located on the lower side of the bottom surface of the iron removal box. The metal detector is connected to the power control terminal of the first and second electromagnetic adsorption plates.

[0005] A preferred technical solution of the present invention is as follows: a support frame is fixedly connected to the bottom of the outlet end of the belt conveyor, and a slot is provided at the bottom of the support frame, in which the iron removal box is slidably engaged.

[0006] The preferred technical solution of the present invention is as follows: a power supply is fixedly connected to the front end face of the iron removal box, and the power supply is electrically connected to the first electromagnetic adsorption plate and the second electromagnetic adsorption plate respectively; two sets of metal detectors are provided, which are respectively mounted above the feed inlet and discharge outlet of the belt conveyor through support frames; the signal output terminals of the two sets of metal detectors are connected to the control terminal of the power supply.

[0007] The preferred technical solution of the present invention is as follows: the discharge port of the iron removal box is provided with a rotatable flip cover, the flip cover is rotatably connected above the discharge port, and a flip cover limiting mechanism is provided at the connection between the flip cover and the iron removal box, and the flip cover is limited by the flip cover limiting mechanism when the flip cover is open.

[0008] A preferred technical solution of the present invention is that there are two of each of the first and second connecting posts, and they are symmetrically distributed.

[0009] The preferred technical solution of the present invention is as follows: the flip cover limiting mechanism includes a fixed block fixedly connected to the side wall of the iron removal box and a limiting post threadedly connected to the inside of the fixed block, and a connecting block is fixedly connected to the outside of the limiting post; the inside of the flip cover is provided with a limiting groove, and in the limiting state, the end of the limiting post away from the connecting block is engaged with the inside of the limiting groove.

[0010] This utility model has the following beneficial effects:

[0011] (1) This utility model includes a detector and an iron removal box. The iron removal box is installed between two belt conveyors or at the outlet of the belt conveyor. The detector is installed above the conveyor belt. When the belt conveyor is used to transport the ore, after the detector detects that the ore contains metal fragments, the power is turned on to drive the first electromagnetic adsorption plate and the second electromagnetic adsorption plate to run. When the ore enters the iron removal box, it is first blocked by the interceptor frame, so that the larger foreign objects are intercepted. The remaining ore falls to the bottom of the iron removal box after being adsorbed by the first electromagnetic adsorption plate and the second electromagnetic adsorption plate, which avoids the blockage of the ore flow channel by larger foreign objects and helps to improve the iron removal efficiency of the device.

[0012] (2) This utility model sets up a flip cover, a limiting post and a connecting block. The connecting block is used to turn the limiting post to release the limiting of the rotating plate, and the rotating plate is flipped. Then the connecting block is used to drive the limiting post to rotate, so as to engage with the inside of the limiting groove and realize the limiting of the flip cover. This makes it easy to open the discharge port of the iron removal box, so as to facilitate the conveying of the ore inside the iron removal box. It can also make it easy to clean the iron impurities adsorbed on the electromagnetic adsorption plate. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] An intelligent iron removal device for the protection of a TBM belt conveyor is provided in the embodiment, with reference to... Figure 1-4 The system includes a belt conveyor 1, which is mainly installed at the mine outlet to transport ore or soil excavated from the mine to the next conveyor. Due to the height difference between the mine and the ground, the system requires the belt conveyor 1 to transport the soil upwards from the mine. Therefore, in this embodiment, the discharge end of the belt conveyor 1 is at the higher end. The iron removal device includes a metal detector 3 installed above the belt conveyor 1 and an iron removal box 2 located at the outlet end of the belt conveyor 1. Two sets of metal detectors 3 are respectively mounted above the inlet and outlet of the belt conveyor 1 via support frames 9. The bottom of the outlet end of the belt conveyor 1 is fixedly connected to the support frame 9, and the bottom of the support frame 9 has a slot 14, in which the iron removal box 2 is slidably engaged.

[0020] In the embodiments, as shown Figures 1 to 4 As shown, the iron removal box 2 has a feed inlet at the top and an interceptor frame 4 at the feed inlet. The gap of the interceptor frame 4 is larger than the particle size of normal ore or soil, but less than 5-10 cm, which can intercept larger foreign objects. The iron removal box 2 is equipped with multiple first electromagnetic adsorption plates 5 and multiple second electromagnetic adsorption plates 6. The first electromagnetic adsorption plates 5 and the second electromagnetic adsorption plates 6 are staggered below the interceptor frame 4. The side of each of the multiple first electromagnetic adsorption plates 5 away from the second electromagnetic adsorption plates 6 is fixed to the first connecting column 10. The multiple second electromagnetic adsorption plates 6... The side furthest from the first electromagnetic adsorption plate 5 is fixed to the second connecting post 11. The upper and lower ends of the first connecting post 10 and the second connecting post 11 are respectively fixed to the top and bottom plates of the iron removal box 2. Each electromagnetic adsorption plate is inclined, and the side of each electromagnetic adsorption plate closest to the connecting post it is higher than the side furthest from the connecting post. A power supply 12 is fixedly connected to the front end of the iron removal box 2, and the power supply 12 is electrically connected to both the first electromagnetic adsorption plate 5 and the second electromagnetic adsorption plate 6. The signal output terminals of the two sets of metal detectors 3 are connected to the control terminals of the power supply 12. There are two of each of the first connecting post 10 and the second connecting post 11, and they are symmetrically distributed. Setting two first connecting posts 10 and two second connecting posts 11 helps to enhance the stability of the connection between the first electromagnetic adsorption plate 5 and the second electromagnetic adsorption plate 6.

[0021] After the ore enters the iron removal box 2, it is blocked by the interceptor frame 4, which intercepts larger foreign objects. The remaining ore falls to the bottom of the iron removal box 2 after being attracted by the first electromagnetic adsorption plate 5 and the second electromagnetic adsorption plate 6. This prevents larger foreign objects from blocking the ore flow channel and helps improve the iron removal efficiency of the device. The bottom of the iron removal box 2 is inclined, which facilitates the sliding of the ore. When the ore slides onto the belt conveyor below, it can effectively avoid damage to the conveyor belt of the belt conveyor below. The first connecting column 10 and the second connecting column 11 can be removed from the first fixing block 9, so as to clean the iron metal and other materials attracted by the first electromagnetic adsorption plate 5 and the second electromagnetic adsorption plate 6 and remove larger foreign objects.

[0022] In the embodiments, as shown Figures 1 to 4 As shown, the bottom of the iron removal box 2 is inclined, and a discharge port 8 is provided on the side of the iron removal box 2, with the discharge port 8 located on the lower side of the bottom surface of the iron removal box 2. A rotating flip cover 13 is provided at the discharge port 8 of the iron removal box 2. The flip cover 13 is rotatably connected above the discharge port 8. A flip cover limiting mechanism 7 is provided at the connection between the flip cover 13 and the iron removal box 2, and the flip cover 13 is limited by the flip cover limiting mechanism 7 when it is open. The flip cover limiting mechanism 7 includes a fixing block 700 fixedly connected to the side wall of the iron removal box 2 and a limiting post 701 threadedly connected to the inside of the fixing block 700. A connecting block 702 is fixedly connected to the outside of the limiting post 701. A limiting groove 703 is opened inside the flip cover 13. In the limited state, the end of the limiting post 701 away from the connecting block 702 is engaged with the inside of the limiting groove 703.

[0023] A fixed column is fixedly connected to the inner wall of the iron removal box 2. The flip cover 13 is rotatably mounted on the fixed column on one side. The flip cover can rotate along the fixed column. The limiting column 701 is installed using the second fixing block 700, and the limiting column 701 can be rotated by rotating the connecting block 702. When the flip cover 13 of this utility model is opened, the limiting column 701 is turned by the connecting block 702 to release the limiting of the flip cover 13, and the flip cover 13 is flipped. Then, the limiting column 701 is rotated by the connecting block 702, thereby engaging with the inside of the limiting groove 703 to limit the flip cover 13. This makes it easy to directly drop the iron-removed ore onto the conveyor belt of the TBM belt conveyor below for transportation when the device is in use.

[0024] The working process of this utility model is as follows: Due to the height difference between the mine shaft and the ground, the device requires a belt conveyor 1 to transport the ore from the mine shaft upwards. After detection by two sets of metal detectors 3, it is determined that there are metal fragments inside. The power supply 12 is then activated to drive the first electromagnetic adsorption plate 5 and the second electromagnetic adsorption plate 6. The ore enters the iron removal box 2 from the output port of the belt conveyor 1 and is blocked by the interceptor frame 4, thus intercepting larger foreign objects. The remaining ore falls off after being adsorbed by the first electromagnetic adsorption plate 5 and the second electromagnetic adsorption plate 6. The bottom of the iron removal box 2 is inclined to prevent large foreign objects from blocking the ore flow channel, which helps to improve the iron removal efficiency of the device. The bottom of the iron removal box 2 is inclined to facilitate the sliding of the ore. By using the connecting block 702 to turn the limiting post 701 to release the limit on the flip cover 13, the flip cover 13 is flipped over. Then, the connecting block 702 drives the limiting post 701 to rotate, thereby engaging with the inside of the limiting groove 703 to limit the flip cover 13. This makes it easy for the iron-removed ore to fall directly onto the conveyor belt of the TBM belt conveyor below for transportation when the device is in use.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
