Description

Technical Field

[0001] The utility model relates to the technical field of ore extraction, and specifically relates to an ore extraction device. Background Art

[0002] Gold ore usually goes through processes such as crushing and grinding to break the ore into particle sizes suitable for further processing, and then the metal is extracted through a flotation device. First, air bubbles are injected into the flotation tank to adsorb the target mineral particles in the ore slurry, making them float on the liquid surface of the flotation tank to achieve the separation and extraction of the ore. However, when the existing extraction devices crush the ore, they uniformly crush the ore without multi-stage crushing. But without multi-stage crushing of the ore, additional steps and workload are required during the extraction process to separate ores of different particle sizes, reducing the extraction efficiency. Moreover, without fine multi-stage crushing of the ore, the equipment inside the extraction device is more likely to be damaged, shortening its service life. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an ore extraction device, which has the advantages of being able to crush the ore step by step, making the mechanical crushing process easier and more efficient, and solves the problem that the extraction efficiency is reduced due to the lack of multi-stage crushing of the ore.

[0004] To solve the above technical problems, the utility model provides the following technical solutions:

[0005] An ore extraction device includes a base of the entire device carrier. A crushing mechanism for crushing the ore is provided on the base. A flotation tank for separating metal substances is provided on the base. A material distribution component for expanding the feeding range is also provided. The crushing mechanism includes a ring body rotatably installed on the base. A grinding roller that rotates in the opposite direction to the ring body is also installed on the base. The diameter of the grinding roller gradually increases from top to bottom. Crushing teeth are fixedly connected to both the inner circle of the ring body and the outer circle of the grinding roller. The ring body is sleeved outside the grinding roller.

[0006] Preferably, a motor is fixedly installed on the base. The output end of the motor is fixedly connected to a transmission shaft. A gear ring is sleeved on the ring body. The output end of the transmission shaft is fixedly connected to a spur gear for driving the ring body to rotate. The spur gear is in meshing transmission with the gear ring.

[0007] Preferably, a connecting shaft is rotatably installed on the base. The grinding roller is fixedly connected to the connecting shaft. A transmission component is provided between the connecting shaft and the transmission shaft.

[0008] Preferably, the material distribution component includes a bearing plate fixedly connected to the connecting shaft. A material distribution plate is fixedly connected to the bearing plate. A guide plate for conveying the ore is fixedly connected inside the material distribution plate. The guide plate is spiral. A guide opening is also provided on the material distribution plate.

[0009] Preferably, the transmission assembly includes pulleys sleeved on the connecting shaft and the transmission shaft, and the pulleys are connected by belt drive.

[0010] Preferably, a material guiding frame is provided on the base, and the material guiding frame is located above the base.

[0011] By means of the above technical solution, the present utility model provides an ore extraction device, which at least has the following beneficial effects:

[0012] 1. For this ore extraction device, by setting the crushing mechanism, since the grinding roller and the ring body rotate in opposite directions, the ore can be crushed by the crushing teeth. And because the grinding roller is frustum-shaped, the ore can be crushed step by step, and the raw material can be decomposed into smaller particles, making the mechanical crushing process easier and more efficient, improving the overall crushing efficiency. The crushed ore particles are smaller and have a larger surface area, which is beneficial to the contact and adsorption of the extracted substances, thereby improving the extraction efficiency.

[0013] 2. For this ore extraction device, the material guiding plate is spiral and can guide the ore to the material guiding port. Since the material distributing plate is in a rotating state, the feeding range of the ore can be increased, so that the ore can be evenly distributed at various positions inside the ring body and the grinding roller when the ore is fed, which helps to ensure the uniformity and stability of the crushing process.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The problems existing in traditional ore extraction devices mainly include low extraction efficiency, energy waste, high cost, etc. To solve these problems, a new type of ore extraction device is designed and adopts multi-stage crushing technology.

[0025] This ore extraction device uses advanced multi-stage crushing technology to perform multi-stage crushing of raw ore into coarse, medium and fine particles, and separately extract the useful minerals therein. Through fine multi-stages, not only the extraction efficiency is improved, the energy consumption is reduced, but also the amount of waste residue generated is reduced. This technology has great application potential in the field of ore extraction, can improve the extraction rate, reduce the production cost, protect the environment, and has received extensive attention and research.

[0026] Embodiment 1:

[0027] Since directly crushing ores with different particle sizes together without multi-stage crushing will result in uneven ore particle sizes and it is difficult to improve the extraction efficiency. Fine particles may not be fully broken and the useful minerals cannot be completely extracted. To solve the above problems, in combination with Figures 1 - 3 As shown, an ore extraction device provided by the present invention is provided with a crushing mechanism 200 for crushing ores on a base 100, and a flotation tank 101 for separating powder substances. The crushed ore particles are smaller and have a larger surface area, which is beneficial to the contact and adsorption of extraction substances, thereby improving the extraction efficiency. It is also provided with a feeding component 300 for expanding the feeding range, which can guide the ore to various positions for crushing and processing by the crushing mechanism 200, facilitating the crushing of the ore.

[0028] Since ores that are not crushed step by step are likely to produce a large amount of waste residue and dust, polluting the environment and wasting resources. To reduce the occurrence of waste residue and dust, the ring body 201 rotatably installed on the base 100 is rotated. A grinding roller 202 that rotates in the opposite direction to the ring body 201 is also installed on the base 100. The diameter of the grinding roller 202 gradually increases from top to bottom. Crushing teeth 203 are fixedly connected to both the inner ring of the ring body 201 and the outer ring of the grinding roller 202. The ring body 201 is sleeved outside the grinding roller 202. Ores fall between the ring body 201 and the grinding roller 202. Since the grinding roller 202 and the ring body 201 rotate in opposite directions, the ores can be crushed by the crushing teeth 203. And because the grinding roller 202 is frustum-shaped, the ores can be crushed step by step, and the raw materials can be decomposed into smaller particles, making the mechanical crushing process easier to carry out and more efficient, and improving the overall crushing efficiency.

[0029] If the ring body 201 and the grinding roller 202 rotate in the same direction, due to the restraint of the rotational force, the ores may not be fully crushed, and some useful minerals cannot be effectively extracted, reducing the extraction efficiency. To improve the extraction efficiency, a motor 204 is fixedly installed on the base 100. The output end of the motor 204 is fixedly connected to a transmission shaft 205. A toothed ring 207 is sleeved on the ring body 201. The output end of the transmission shaft 205 is fixedly connected to a spur gear 206 for driving the ring body 201 to rotate. The spur gear 206 is in meshing transmission with the toothed ring 207. When the motor 204 is started to drive the transmission shaft 205 to rotate, the spur gear 206 rotates with the transmission shaft 205. The spur gear 206 drives the ring body 201 to rotate through the toothed ring 207, and then the ring body 201 can be driven to operate to crush the ores. The ring body 201 and the grinding roller 202 rotate in opposite directions. Through this design, the friction and collision between the two can more effectively achieve the crushing effect and improve the crushing efficiency.

[0030] Further, a connecting shaft 208 is rotatably installed on the base 100. The grinding roller 202 is fixedly connected to the connecting shaft 208. A transmission assembly 209 is provided between the connecting shaft 208 and the transmission shaft 205. The transmission assembly 209 includes belt pulleys sleeved on the connecting shaft 208 and the transmission shaft 205. The belt pulleys are connected by a belt in transmission connection. The transmission shaft 205 drives the connecting shaft 208 to rotate through the transmission assembly 209, and can drive the grinding roller 202 to rotate. Thus, the rotation of the ring body 201 and the grinding roller 202 can be realized through a single power source, and the manufacturing cost of the equipment can be reduced.

[0031] According to the embodiment, in the process of step-by-step crushing, the raw materials are crushed multiple times, and a part of the particles are reduced each time, which can reduce wear and extend the service life of the crushing equipment.

[0032] Embodiment Two:

[0033] If the material guiding port 303 is always in a fixed position, it will cause uneven distribution of the ore in the annular crushing device. Some ores may be subjected to uneven crushing, affecting the crushing effect. To solve the above problems, in combination with Figure 1 and Figure 4 As shown, on the basis of the first embodiment, the material distribution assembly 300 includes a load-bearing plate 304 fixedly connected to the connecting shaft 208. A material distribution plate 301 is fixedly connected to the load-bearing plate 304. A material guiding plate 302 for conveying ore is fixedly connected inside the material distribution plate 301. The material guiding plate 302 is spiral. A material guiding port 303 is also provided on the material distribution plate 301. The rotation of the connecting shaft 208 can drive the material distribution plate 301 on the load-bearing plate 304 to rotate. The material guiding plate 302 rotates with the material distribution plate 301. Since the material guiding port 303 is provided at the end position of the material guiding plate 302 and the material guiding plate 302 is spiral, it can guide the ore to the material guiding port 303. Since the material distribution plate 301 is in a rotating state, the feeding range of the ore can be increased, so that the ore can be evenly distributed at various positions inside the ring body 201 and the grinding roller 202 when the ore is fed, which helps to ensure the uniformity and stability of the crushing process.

[0034] Furthermore, a material guiding frame 102 is provided on the base 100. The material guiding frame 102 is located above the base 100 and can continuously introduce the ore into the material distribution plate 301.

[0035] As can be seen from the above embodiments: First, start the machine. The ore enters the material distribution plate 301 through the material guiding frame 102, and then the ore falls between the ring body 201 and the grinding roller 202. At the same time, the motor 204 drives the transmission shaft 205 to rotate. The spur gear 206 rotates with the transmission shaft 205, and the spur gear 206 drives the ring body 201 to rotate through the gear ring 207. Since the grinding roller 202 and the ring body 201 rotate in opposite directions, the ore can be crushed by the crushing teeth 203. The processed powder falls into the flotation tank 101 below, and the flotation tank 101 sorts the gold in the powder, so that the gold in the ore can be extracted.

[0036] It should be noted that the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or apparatus that comprises a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
