Description

Technical Field

[0001] This invention relates to the fields of metallurgy and mineral engineering, specifically to a crushing and iron removal device for mineral processing waste rock. Background Technology

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself possesses certain usable properties. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, while other ores are usually expressed as a percentage. Ore grade is often used to measure the value of ore. However, the composition of gangue (useless minerals or minerals with very low content of useful components that cannot be utilized) and the amount of harmful impurities in ores with the same effective components also affect the value of ore.

[0003] Chinese patent CN214077233U discloses a magnetic sorting machine for pre-selecting and removing waste rock in mining. Through the installation of a hydraulic rod, a magnetic plate can be brought close to the iron ore, facilitating its adsorption. A first motor, threaded rod, and threaded sleeve allow the magnetic plate to move along the conveyor belt, increasing the contact area with the iron ore and further enhancing its adsorption. When the magnetic plate with adsorbed iron ore rotates to the top of the collection box, an electric push rod and scraper scrape the iron ore off. Under gravity, the iron ore falls into the collection box, while the waste rock is transported elsewhere by the conveyor belt, thus achieving the sorting of iron ore.

[0004] However, when the iron ore is transported and discharged by a conveyor belt, the iron ore is easily thrown out due to the inertia of the conveyor belt, causing it to impact the collection box and potentially damaging it. Furthermore, the iron ore is discharged from a single point and tends to accumulate in one place, which is not conducive to the collection box's ability to collect the iron ore. Summary of the Invention

[0039] Please refer to Figure 8This embodiment provides a mineral processing waste rock iron removal and crushing device.

The number of tensioning wheels 3875 is greater than two sets. The bottom of tensioning wheel 3875 is in contact with conveyor belt 35.

[0040] Example 2:

[0041] This embodiment provides a mineral processing waste rock iron removal and crushing device, such as... Figure 5 As shown, the right end of the inclined plate 3831 is provided with an embedding groove 383a, and the inner front and rear end walls of the embedding groove 383a are provided with rubber pads 383b. When the collection module 4 approaches the inclined plate 3831, the handrail on the collection module 4 will be embedded in the embedding groove 383a. The rubber pads 383b limit the handrail on the collection module 4, thereby assisting in the positioning of the collection module 4 and facilitating the placement of the collection module 4.

[0042] The tensioning wheel 3875 on the far right can be equipped with a cleaning brush 3877. The cleaning brush 3877 wraps around the surface of the tensioning wheel 3875 and comes into contact with the surface of the conveyor belt 35, which can assist in cleaning the surface of the conveyor belt 35, increase the service life of the conveyor belt 35, and increase the functional versatility of the tensioning structure 387.

[0043] During use, the ore beneficiation waste rock is transported through the conveyor belt module 1, and the iron removal module 3 is activated at the same time. When the waste rock passes the bottom of the magnet 37, the iron ore is absorbed by the magnetic force on the magnet 37.

[0044] At the same time, the servo motor 32 drives the conveyor belt 33 to rotate, thereby driving the conveyor roller 34 to rotate and drive the conveyor belt 35 to rotate on the conveyor roller 36, thereby conveying the adsorbed iron ore to the right end of the conveyor belt 35. As the iron ore is conveyed to the right end, the magnetic force on the magnet 37 decreases, and due to its own gravity, the iron ore is discharged to the right end of the conveyor belt 35. The remaining ore is conveyed to the crushing module 2 through the conveyor belt module 1 for crushing and collection.

[0045] When the iron ore is discharged at the right end of the conveyor belt 35, it is guided by the inclined plate 3831 and the buffer plate 3834. At the same time, the buffer plate 3834 will compress the spring 3835 to deform and absorb the impact force on the iron ore. While preventing the iron ore from being thrown out, it can buffer and guide the iron ore to prevent it from hitting the end wall of the collection module 4 and increase the service life of the collection module 4. Meanwhile, the drive motor 382 drives the inclined plate 3831 to swing through the movable rod 3833. Adjusting the tilt angle of the inclined plate 3831 can guide the iron ore to different positions in the collection module 4 and prevent the iron ore from accumulating at one point.

[0046] Furthermore, by setting up a tensioning and guiding mechanism 38, the tensioning wheel 3875 is in contact with the upper right end wall of the conveyor belt 35. While guiding the conveyor belt 35, the tensioning force on the spring damper 3871 can keep the tensioning wheel 3875 in close contact with the conveyor belt 35, tensioning the conveyor belt 35 and preventing it from becoming loose, which would affect the efficiency of conveying iron ore. In addition, multiple tensioning wheels 3875 are added to increase the contact pairs with the conveyor belt 35, making the conveyor belt 35 convey smoothly.

[0047] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
