DETAILED DESCRIPTION

[0031] Now the present invention will be further described in detail with reference to the accompanying drawings:

[0032] Ore refers to rocks containing useful minerals and worth mining, or natural aggregates of minerals in the earth's crust, from which metals or other mineral products necessary for the national economy can be extracted on an industrial scale under modern technological and economic conditions.

[0033] Ore is a stone containing some valuable minerals mined from mines. After crushing, grinding and other processing, it can be used in many engineering fields.

[0034] According to the types of metals contained, it can be divided into metal ores and non-metal ores. Metal ores include iron ore, copper ore, etc.; non-metal ores include graphite, quartz, etc.

[0035] According to their causes and formation conditions, they can be divided into endogenous ores, exogenous ores and metamorphic ores.

[0036] Ore processing refers to the process of selecting, purifying and processing raw ore through a series of physical, chemical and metallurgical processes to finally obtain the desired metal or non-metallic products.

[0037] It mainly includes: the initial crushing of the original ore to make it smaller particles to prepare for the subsequent process. Through physical sorting methods such as magnetic separation, flotation, gravity separation, etc., the ore is divided into different groups according to its different physical properties (such as magnetism, density, hydrophilicity, etc.) for subsequent processing and extraction. Applicable to ores containing magnetic minerals. Magnetic minerals are separated from non-magnetic ores by using magnetic force to achieve concentration and purification. A common ore separation technology that is applicable to many metal ores. This technology is based on the different hydrophilicity of ore and chemical reagents added to water, and uses bubbles to adsorb on the surface of ore particles to separate valuable minerals from waste minerals. Applicable to ores with obvious density differences, such as gold, iron, etc. Gravity or centrifugal force is used to separate different density components in the ore to achieve purification and separation. The ore after preliminary sorting is further refined to achieve the required particle size for subsequent processes. The target metal or non-metal is extracted and refined and processed through chemical and metallurgical processes to obtain the desired final product. For some metal ores, after the previous pretreatment, sintering or smelting process is required, such as blast furnace smelting of iron ore. The remaining waste slag and tailings are processed to reduce the impact on the environment and recover the useful resources in them.

[0038] Multi-stage ore crushing is an important part of ore processing, which aims to reduce the particle size of large ore through multiple crushing to meet the needs of subsequent processing or use. Multi-stage ore crushing means that large ore is crushed through two or more crushing equipment, and then crushed into coarse, medium and fine pieces to achieve the required particle size. This crushing method can improve crushing efficiency, reduce energy consumption, and also help optimize the particle size distribution and shape of the ore.

[0039] There are many types of equipment in mines, such as ore dressing equipment, crushing equipment, sand making equipment, washing equipment, and grinding equipment. These mining machinery and equipment have their own uses and advantages, and include different models. Next, we will discuss the main types.

[0040] Mining crushing equipment: Crushing equipment is mainly used to crush various stones after mining, and crush them into different sizes and specifications according to needs for use in different places. Commonly used crushers are: primary crushing of stones - jaw crusher, medium and fine crushing - impact crusher or cone crusher, direct crushing and one-time forming - hammer crusher.

[0041] Mining sand making equipment: Mining stones become gravel after crushing. If you want to make it into machine-made sand, you need a sand making machine. Common sand making equipment includes impact sand making machine, vertical composite sand making machine, roller sand making machine, and fine crusher. They can all make stones into 0-5mm size and directly used as construction sand.

[0042] Mining washing equipment: Generally, wet sand making production lines will use washing equipment to clean excess stone powder in sand and gravel and to ensure reasonable grading. Bucket sand washing machines and spiral sand washing machines are commonly used, with large output and high washing efficiency.

[0043] Mining grinding equipment: If finer stone powder is needed, a grinding mill is needed. Commonly used grinding mills include vertical grinding mills and Raymond grinding mills (large pendulum grinding mills), and the output size is between 40-425 meshes; if finer, between 400 meshes and 2500 meshes, use ultra-fine vertical grinding mills or ring roller grinding mills. The grinding mill can adapt to a variety of stone materials and run smoothly. For example, calcite, quartz stone, dolomite and other mineral materials. Not only that, some high-quality grinding mills can achieve multi-purpose use, and can even grind metal ores, metallurgical solid waste, coal powder, carbon powder, refractory materials, and chemical raw materials. After grinding, these materials are widely used in coal mining, cement, slag, metallurgy, chemical industry and other powder making fields, achieving high value development.

[0044] Through the eccentric rotation of the cone crushing head, the crushed ore rolls onto the surface of the screen plate. The screen plate follows the rotation of the cone crushing head, so that the falling crushed ore rotates and tilts with the screen plate, increasing the residence time of the ore on the surface of the screen plate and the screening and grading efficiency. The crushed small particles of ore fall onto the surface of the folding screen ring plate through the screening holes of the screen plate. The small pieces of ore are further screened by the folding screen ring plate. The screened ore is graded and dispersed into the inside of the first-level sub-cavity, while the ore staying on the surface of the folding screen ring plate is tilted and guided by the folding screen ring plate to the inside of the second-level sub-cavity, thus completing the crushing, grading and screening of the ore.

[0045] See also Figure 1-4 As shown, in this embodiment, a multi-stage ore crushing and refining device for ore processing is provided, including a support component 1 and a processing component 2;

[0046] The support assembly 1 includes a support plate 101, a grounding block 102 is provided at the bottom of the support plate 101, a fine material outlet 103 is provided at the bottom of the support plate 101, a coarse material outlet 104 is provided at the bottom of the support plate 101 and on one side of the fine material outlet 103, a transmission 105 is provided at the top of the support plate 101, and a transmission box 106 is provided at the top of the support plate 101. The support assembly 1 not only ensures the stability and safety of the overall structure through the reasonable layout of various functional units, but also promotes the effective classification and processing of materials in the filtration process, thereby improving the working efficiency and reliability of the entire valve.

[0047] The processing component 2 includes a connection box 201 and a transmission cylinder 203. The connection box 201 is fixedly arranged on the top of the transmission box 106. The top of the connection box 201 is provided with a vibration box 202. The transmission cylinder 203 is fixedly arranged on the top of the support plate 101. A protruding rotating wheel 204 is arranged on the bottom side of the transmission cylinder 203. An elliptical wheel 205 is arranged on the top side of the transmission cylinder 203. The elliptical wheel 205 is connected to the vibration box 202.

Among them, the vibration box 202 and the elliptical wheel 205 connected thereto work together to enhance the self-cleaning ability of the filtering device; and the connection box 201 and the transmission cylinder 203 ensure that the materials can flow smoothly inside the system. The use of the protruding rotating wheel 204 can further optimize the material conveying path and state. These designs jointly improve the performance and reliability of the entire valve filtration system.

[0048] The innovative introduction of an adjustable reciprocating structure is used to control the material entry speed and amount. This design can be dynamically adjusted according to the properties of the ore, effectively avoiding blockage caused by uneven feeding. By precisely controlling the material feed, it ensures that each crushing stage can operate efficiently, thereby improving the overall crushing efficiency. The addition of a reciprocating structure not only improves the fluidity of the material, but also enhances the anti-blocking ability of the equipment, especially when processing ores with high water content or strong viscosity. It can effectively reduce the residence time of the material in the crushing chamber, reduce the risk of blockage, and ensure production continuity.

[0049] In terms of usage, the support plate 101 and the grounding block 102 are used to support and control the object, and the transmission box 106 and the transmission 105 are used to stably connect the object. The transmission of the transmission cylinder 203 and the connection of the transmission 105 can control the rotation of the elliptical wheel 205, so as to adjust and control the rotation of the vibration box 202, facilitate the entry of the object, and prevent blockage.

[0050] In this embodiment, the support plate 101 is in the shape of a square plate, and the grounding block 102 is in the shape of an inverted U. The grounding blocks 102 are symmetrically arranged, so as to be used for supporting connection, and facilitate the subsequent control of stable support of the top object. By combining the support plate 101 with the grounding blocks 102 in the shape of an inverted U and arranged in a symmetrical manner, the design scheme can effectively achieve stable support for the top object. This combination not only takes into account the basic principles of structural mechanics, that is, how to reasonably distribute the load and how to resist external interference forces, but also takes into account the convenience and safety in actual use.

[0051] In this embodiment, a power motor 1051 is provided on one side of the transmission 105, and a rotating wheel 1052 is provided on one side of the transmission 105. The transmission 105 is used as a whole to provide power, and the power motor 1051 is used to provide power to the transmission 105. The advantages of this configuration are its flexibility and controllability. Through the adjustment of the transmission 105, the speed and torque of the output end can be flexibly adjusted to adapt to different workloads or environmental conditions without changing the output of the power motor 1051. This design also has high efficiency because the power motor 1051 is directly connected to the transmission 105, reducing the loss of energy during the transmission process. At the same time, such a structure is also convenient for maintenance and repair because the connection between the various components is clear and definite, and it is easy to disassemble and reassemble.

[0052] In this embodiment, a second wheel 1061 is provided on one side of the transmission box 106, and the first wheel 1052 and the second wheel 1061 are meshed, so as to realize the adjustment control to transmit the power of the transmission 105 to the transmission box 106, wherein the structure and principle of the transmission 105, the transmission box 106 and the power motor 1051 are well known in the art, and will not be described in this application, and through the above design, the whole system realizes the effective transmission of power from the power source to the final actuator. This structure can not only flexibly adjust the power parameters, but also ensure the efficient transmission of power between different components.

[0053] In this embodiment, a movable cylinder 2021 is slidably provided on the top of the vibration box 202, a protruding plate 2022 is provided on one side of the movable cylinder 2021, and a feed port 2023 is provided through the top of the vibration box 202. The movable cylinder 2021 is reciprocated up and down to achieve the controlled movement of the regulated object, which is convenient for subsequent control and adjustment. Through the reciprocating up and down motion of the movable cylinder 2021, the material can be effectively introduced into the vibration box 202 and vibrated in the box. This design not only improves the efficiency of material processing, but also enhances the automation of the system and reduces the need for manual intervention.

[0054] In this embodiment, the interior of the transmission cylinder 203 is hole-shaped, and the protruding rotating wheel 204 is connected to the second rotating wheel 1061, so as to achieve the function of adjusting and controlling power transmission. The hole-shaped design inside the transmission cylinder 203 provides necessary space and protection for the transmission components inside it. The connection between the protruding rotating wheel 204 and the second rotating wheel 1061 realizes the power transmission from the transmission 105 to the transmission cylinder 203. This design allows the system to adjust the power parameters as needed, so that it can maintain efficient operation under different working conditions.

[0055] In this embodiment, an elliptical wheel 205 is provided on one side of the transmission cylinder 203, and the elliptical wheel 205 runs through the transmission cylinder 203 and is provided with a passive wheel 2051. The protruding wheel 204 and the passive wheel 2051 are connected by a transmission belt 206 to realize power transmission, wherein the control of the lifting and lowering of the movable cylinder 2021 can be adjusted by the rotation of the elliptical wheel 205. The transmission cylinder 203 realizes power transmission from the power source to the elliptical wheel 205 through the elliptical wheel 205 and the passive wheel 2051 inside it, and the protruding wheel 204 and the transmission belt 206 outside. The rotation of the elliptical wheel 205 further controls the lifting and lowering of the movable cylinder 2021 through a mechanical mechanism, thereby completing the material processing task. This design not only improves the flexibility and controllability of the system, but also ensures the efficiency and reliability of power transmission.

[0056] In this embodiment, the elliptical wheel 205 is connected to the protruding plate 2022 on one side of the vibration box 202, and the structure of the elliptical wheel 205 causes the movable cylinder 201 on one side of the vibration box 202 to vibrate up and down. When the elliptical wheel 205 starts to rotate, due to its non-circular shape, it generates a constantly changing contact force with the protruding plate 2022 on one side of the vibration box 202. This changing contact force causes the protruding plate 2022 and the entire vibration box 202 to move up and down.

[0057] In this embodiment, one side of the connecting box 201 is conical, and the bottom of the connecting box 2021 passes through the stirring mechanism inside the transmission box 106. This special design of the connecting box 201 not only optimizes the flow path of the material, but also enhances the effect of subsequent processing steps, thereby improving the working efficiency and performance of the entire filtering device.

[0058] In this embodiment, the output end of the transmission box 106 is connected to the coarse material outlet 104, and the transmission box 106 is connected to the side of the fine material outlet 103. A filter is provided at the input end of the fine material outlet 103. This design not only enhances the filtering efficiency, but also simplifies the maintenance process, because the filter can be cleaned regularly to keep the system in good operating condition. At the same time, it also ensures the high quality of the output material to meet specific application requirements.

[0059] In summary, the comparative documents have described a structure that can be used for crushing and refining. The present application improves upon it by providing an adjustable and controlled reciprocating structure that can facilitate the control of the entry of objects, thereby preventing blockage.
