Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment, and in particular to a hopper for a mineral processing machine and mineral processing equipment. Background Technology

[0002] Mineral processing is a process that, based on the physical and chemical properties of different minerals in an ore, involves crushing and grinding the ore, and then using methods such as gravity separation, flotation, and magnetic separation to separate the ore from waste rock, remove or reduce harmful impurities, and obtain raw materials needed for smelting or other industries. Chinese patent application number CN202311470622.6 discloses a fine-material beneficiation device for titanium ore mining and processing, including a base, a material conveying module, a feeding module, a magnetic conveying module, and a material handling assembly. The feeding module feeds the ore into the material conveying module, which then transports the ore to the magnetic conveying module via a horizontally arranged belt drive. Iron ore is attracted and transported by the magnetic conveying module, while the remaining ore is discharged with the material conveying module. This patent achieves both transportation and separation of ore and waste rock through belt conveying.

[0003] However, in the existing technology, the material conveying module and magnetic conveying module for conveying and sorting minerals in such equipment are relatively long, resulting in a large horizontal footprint and requiring a large installation space. Furthermore, the maintenance and repair of the belt conveyor system are quite difficult and require a long maintenance time, which affects production efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a feeding hopper for a mineral processing machine and mineral processing equipment.

[0005] A hopper for a mineral processing machine includes: a feeding unit with its axis extending vertically; a first feed inlet and a second feed inlet at the upper end of the feeding unit, the second feed inlet surrounding the outside of the first feed inlet; a first discharge outlet and a second discharge outlet at the lower end of the feeding unit, the second discharge outlet surrounding the outside of the first discharge outlet; the first discharge outlet and the first feed inlet are connected, and the second discharge outlet and the second feed inlet are connected; the channel between the first feed inlet and the first discharge outlet is independent and not connected to the channel between the second feed inlet and the second discharge outlet; and a diversion unit disposed below the feeding unit; the diversion unit has two independent guide channels inside, the two guide channels being connected to the first discharge outlet and the second discharge outlet respectively.

[0006] The feeding hopper for a mineral processing machine described in this utility model, by setting up a feeding unit and a diversion unit with the axis extending vertically, allows ore and waste rock to enter different channels for final separation under the sorting of the mineral processing machine through free fall. It makes comprehensive use of vertical space, reduces the horizontal footprint of the mineral processing equipment, and utilizes the free fall of ore and waste rock for feeding and transportation in the vertical direction. The separation is achieved by changing the movement trajectory through existing equipment such as air valves, eliminating the need for a belt conveyor system for transportation, simplifying maintenance and increasing work efficiency.

[0009] Furthermore, the cross-sectional areas of the first hopper and the second hopper gradually decrease from top to bottom in the vertical direction, forming a downward sloping surface.

[0010] The above technical solution guides the ore and / or waste rock falling from the upper feed inlet to the lower discharge outlet for discharge.

[0011] Furthermore, the feeding unit also includes reinforcing members, which are respectively laid on the inner peripheral walls of the first hopper and the second hopper.

[0012] The above technical solution protects the inner walls of the first and second hoppers from being damaged by freely falling ore / or waste rock.

[0014] The above technical solution facilitates the disassembly of the second hopper for maintenance or replacement, avoiding the waste of replacing the entire hopper when there is partial damage, and saving on operating costs.

[0018] Through the above technical solution, two independent diversion channels receive ore and waste rock respectively, and transfer them to ore storage bins and waste rock storage bins, thereby achieving the separation of ore and waste rock.

[0019] Furthermore, the diversion unit also includes a second connecting plate, which covers the upper ends of the first and second flow guides and is fixedly connected to them; the surface of the second connecting plate has clearance openings that are respectively connected to the first flow guide inlet and the second flow guide inlet; the lower end of the feeding unit also has a third connecting plate protruding, which extends horizontally; the surfaces of the third connecting plate and the second connecting plate are attached and fixedly connected.

[0020] By using the above technical solutions, the contact area between the feeding unit and the diversion unit is increased, making the connection between the two more stable.

Detailed Implementation

[0026] To address the drawbacks of existing mineral processing equipment that uses belt conveyors for ore separation, such as large footprint and difficult maintenance, the applicant provides a feeding hopper for a mineral processing machine. This hopper includes a feeding unit and a diversion unit. A first hopper of the feeding unit is embedded inside a second hopper, forming an ore channel at the center of the feeding unit and a waste rock channel surrounding the ore channel. The ore and waste rock then flow through the first and second guide sections to different storage bins for separation. The feeding unit and diversion unit comprehensively utilize vertical space, reducing the horizontal footprint. Furthermore, the vertical feeding is achieved using the gravity of the ore and waste rock, eliminating the need for belt conveyors and avoiding the maintenance difficulties associated with belt-driven transport. This reduces the time required for regular maintenance and improves production efficiency. The following is one embodiment of the feeding hopper for a mineral processing machine provided by this utility model: Please refer to Figures 1 to 7 , Figure 1 A schematic diagram of the spatial structure of the feeding hopper for a mineral processing machine provided by this utility model; Figure 2 for Figure 1 Enlarged view of point A in the middle; Figure 3 A schematic diagram of the spatial structure of the feeding unit provided by this utility model from one perspective; Figure 4 A spatial structure diagram of the feeding unit provided by this utility model from another perspective; Figure 5The front view of the feeding unit provided by this utility model projected along the vertical direction; Figure 6 A schematic diagram of the spatial structure of the diversion unit provided by this utility model from one perspective; Figure 7 A schematic diagram of the spatial structure of the diversion unit provided by this utility model from another perspective.

[0027] This utility model provides a feeding hopper 100 for a mineral processing machine, including a feeding unit 1 and a diversion unit 2. The feeding unit 1 is used to receive ore and waste rock to be sorted, and the diversion unit 2 transports the ore and waste rock to different storage bins respectively.

[0028] The feeding unit 1 includes a first hopper 11, a second hopper 12, and a first connecting plate 13. The first hopper 11 has a first inlet 111 and a first outlet 112 at its upper and lower ends along the vertical direction, respectively. The first hopper 11 is disposed inside the second hopper 12 and connected to it by the first connecting plate 13. The second hopper 12 has a second inlet 121 and a second outlet 122 at both its upper and lower ends, and the first inlet 111 and the first outlet 112 are located on the same horizontal plane as the second inlet 121 and the second outlet 122, respectively. Specifically, the outer peripheral wall of the upper end of the first hopper 11 and the inner peripheral wall of the upper end of the second hopper 12 are spaced apart, forming the second feed inlet 121, which surrounds the outside of the first feed inlet 111 circumferentially; the outer peripheral wall of the lower end of the first hopper 11 and the inner peripheral wall of the lower end of the second hopper 12 are spaced apart, forming the second discharge outlet 122, which surrounds the outside of the second discharge outlet 112 circumferentially. The channel from the first feed inlet 111 to the first discharge outlet 112 and the channel from the second feed inlet 121 to the second discharge outlet 122 are independent and not connected. After separation by the ore beneficiation machine, ore enters the feeding unit 1 from the first feed inlet 111 and is discharged from the first discharge outlet 112, while waste rock enters the feeding unit 1 from the second feed inlet 121 and is discharged from the second discharge outlet 122, thereby achieving the separation of ore and waste rock through two independent channels.

[0029] In this embodiment, the second hopper 12 includes a plurality of outer hopper plates 123 and outer hopper connecting plates 124. The plurality of outer hopper plates 123 are spliced ​​together in pairs along the circumference of the second feed inlet 121 to form a semi-closed structure with openings at both ends. The number of outer hopper connecting plates 124 corresponds to the number of outer hopper plates 123, and their ends are respectively attached to the outer peripheral walls of two adjacent outer hopper plates 123 and connected to the two adjacent outer hopper plates 123, so that the connection between the two adjacent outer hopper plates 123 is stable. Compared with one-piece molding, the second hopper 12 formed by splicing multiple outer hopper plates 123 is convenient to disassemble for maintenance or replacement, saving usage costs.

[0030] Furthermore, the outer peripheral wall of the outer material hopper plate 123 is also provided with a handle 1231, which makes it convenient for workers to apply force to lift and disassemble the outer material hopper plate 123.

[0031] Furthermore, the first hopper 11 and the second hopper 12 have a conical structure, and their cross-sectional areas gradually decrease from top to bottom in the vertical direction, forming a downward sloping surface (not shown in the figure), thereby guiding the ore and / or waste rock falling from the upper feed port to converge to the lower discharge port and be discharged.

[0032] The first connecting plate 13 is used to connect the first hopper 11 and the second hopper 12. Specifically, one end of the first connecting plate 13 is connected to the outer peripheral wall of the first hopper 11, and the other end is connected to the inner peripheral wall of the second hopper 12, thereby connecting the first hopper 11 and the second hopper 12. The first connecting plate 13 is located at one end of the second feed inlet 121, so that a connected waste rock channel is formed between the second feed inlet 121 and the second discharge outlet 122. A plurality of first connecting plates 13 are provided, and the plurality of first connecting plates 13 are evenly distributed circumferentially to improve the stability of the connection between the first hopper 11 and the second hopper 12. In this embodiment, the number of first connecting plates 13 is 10.

[0033] Furthermore, the feeding unit 1 also includes reinforcing members 14, which are respectively laid on the inner peripheral walls of the first hopper 11 and the second hopper 12. When ore enters the first hopper 11 through the first feed inlet 111, the ore falls freely and contacts the reinforcing members 14, which protect the first hopper 11 from being damaged by the ore. Similarly, when waste rock enters the second hopper 12 through the second feed inlet 121, the reinforcing members 14 protect the second hopper 12 from being damaged by the waste rock. The reinforcing members 14 can be made of silicone, rubber, polyurethane, etc. In this embodiment, the reinforcing members 14 are rubber parts.

[0034] Furthermore, the first hopper 11, the second hopper 12, and the first connecting plate 13 are all made of sheet metal, thereby improving the structural strength of the first hopper 11, the second hopper 12, and the first connecting plate 13.

[0035] The diversion unit 2 includes a first guide section 21, a second guide section 22, and a second connecting plate 23. The first guide section 21 and the second guide section 22 are two independent guide channels. The upper end of the first guide section 21 has a first guide inlet 211 that communicates with the first discharge port 112, and the upper end of the second guide section 22 has a second guide inlet 221 that communicates with the second discharge port 122. The upper end of the first guide section 21 passes through the outer peripheral wall of the second guide section 22 and extends into the second guide section 22, such that the second guide inlet 221 and the first guide inlet 211 are located on the same horizontal plane, and the second guide inlet 221 surrounds the outside of the first guide inlet 211. The second connecting plate 23 connects the feeding unit 1 and the diversion unit 2. It covers the first guide section 21 and the second guide section 22 and extends horizontally. The surface of the second connecting plate 23 has a clearance opening (not shown) that communicates with the first guide inlet 211 and the second guide inlet 221. The second connecting plate 23, the first guide section 21, and the second guide section 22 can be an integrated design or connected by welding or other methods. A third connecting plate 125 is also provided at one end of the second hopper 12 near the second discharge port 122. The third connecting plate 125 extends horizontally. During assembly, the surfaces of the third connecting plate 125 and the second connecting plate 23 are fitted together and fixedly connected by screws or welding. Thus, the first guide inlet 211 is connected to the first discharge port 112, and the second guide inlet 221 is connected to the second discharge port 122. During operation, the ore is separated by the ore beneficiation machine. The ore passes through the first hopper 11 and enters the first guide section 21 through the first guide inlet 211, and is then transferred to the ore storage bin through the first guide section 21. The waste rock passes through the second hopper 12 and enters the second guide section 22 through the second guide inlet 221, and is then transferred to the waste rock storage bin through the second guide section 22, thereby achieving the separation of ore and waste rock.

[0036] Furthermore, the outer peripheral walls of the first flow guide 21 and the second flow guide 22 are respectively provided with a first inspection door 212 and a second inspection door 222, which facilitates regular maintenance of the interior of the diversion unit 2.

[0037] This utility model also provides a mineral processing device, including a mineral processing machine (not shown) and a hopper 100 for the mineral processing machine. Vertically, the mineral processing machine is positioned above the hopper 100 for separating ore and waste rock in the ore material. Specifically, the mineral processing machine is equipped with a separation unit that identifies the ore and waste rock in the ore material and causes them to fall along different paths, entering the first feed inlet 111 and the second feed inlet 121 respectively to achieve the separation of ore and waste rock. In this embodiment, the sorting unit includes a radiation detection device and an air valve. The radiation detection device and the air valve are arranged horizontally. During operation, the ore falls freely inside the concentrator. The radiation detection device identifies the ore and calculates its position. When the detected ore reaches the air valve, if the detection result is ore, the air valve does not release air, and the ore falls along the middle into the first feed inlet 111. If the detection result is waste rock, the air valve releases air, changing the trajectory of the waste rock, causing it to fall from all sides into the second feed inlet 121, thereby separating the waste rock and ore in the ore. The detailed structure and sorting process of the sorting unit are existing technologies and will not be described in detail here. Furthermore, in the hopper 100, since the first feed inlet 111 is located at the center of the feeding unit 1, and the second feed inlet 121 surrounds the outer periphery of the first feed inlet 111, the air valve can be set around the hopper 100. At this time, both ore and waste rock can be fed 360°, improving the feeding efficiency.

[0038] Compared with existing technologies, the feeding hopper for mineral processing machines provided by this utility model has the following advantages: (1) By making comprehensive use of vertical space to separate ore and waste rock in the feed material, the horizontal area occupied is reduced, making the application range wider.

[0039] (2) The ore and waste rock are transported by free fall in the vertical direction. The separation is achieved by changing the movement trajectory through the air valve. There is no need to use a belt system for transportation. The maintenance is simple and the work efficiency is high.

[0040] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
