Description

Technical Field

[0001] The invention relates to an open-air large-scale ring-type integrated crushing system, belonging to the field of crushing equipment. Background Art

[0002] In the current ore processing industry, ore crushing, as a key link in pretreatment, faces multiple challenges in its on-site conditions. Ore crushing sites are usually equipped with multiple crushers, which are divided into coarse crushers (such as jaw crushers), medium crushers (such as cone crushers) and fine crushers (such as impact crushers) according to their crushing particle sizes. They are closely connected through a complex belt conveyor network, and the on-site equipment layout is complicated. This multi-equipment, multi-link tandem operation mode makes the on-site layout complex and changeable, which not only increases the difficulty of management and safety hazards, but also increases the complexity of troubleshooting and maintenance, while also limiting the improvement of production efficiency.

[0003] In addition, since the ore crushing process requires crushing step by step, each crusher needs to occupy a certain operating space and be equipped with corresponding feeding and conveying equipment. Due to the limited processing capacity of the crusher, as the ore processing volume increases, the number of required equipment also increases, resulting in a large area occupied by the entire crushing production line. This not only increases the cost of land use, but also limits the flexible layout and expansion capabilities of the production line.

[0004] Therefore, in view of the current problems of complex layout of ore crushing site, large space occupation, and many equipment requirements, the industry urgently needs a solution that can optimize the layout, reduce the number of equipment, improve production efficiency, and reduce management difficulty. This is also the technical background for the development of the ore crushing system of this application. Summary of the invention

[0005] The present invention aims to solve the problems of numerous equipment, complex layout, large floor space and difficult management in existing ore crushing production lines, and to provide an open-air large-scale ring-type integrated crushing system to achieve efficient crushing operations through integrated design.

[0006] The open-air large-scale ring-type integrated crushing system described in the present invention includes a crusher body, which includes a cylindrical shell with openings on the top and bottom; it also includes a circular base, which is located in the center of the shell, and the annular area between the base and the inner wall of the shell is divided into multiple crushing units, and the ore crushed by the crushing units is discharged from the bottom of the shell.

[0007] The top and bottom of the cylindrical shell are open for the entry and exit of ore. The annular area between the base and the inner wall of the shell is divided into multiple crushing units, which can be fed and crushed at the same time, making full use of the large annular area between the base and the inner wall of the shell, greatly improving the crushing capacity of the device.

[0008] The annular area between the base and the inner wall of the shell is divided into multiple crushing chambers by multiple partitions distributed in a circumferential array. Each crushing unit includes a crushing chamber and multiple movable crushing plates therein. The multiple crushing plates are arranged in a stepped manner. Under the action of the driving mechanism, each crushing plate can move along the radial direction of the base and can form an extrusion effect with the inner wall of the shell. Since larger ores cannot fall, the ores can be crushed step by step in the stepped crushing chamber.

[0009] Furthermore, jaw plates are installed on the front end surface of the crushing plate and the position corresponding to the crushing plate on the inner wall of the shell, which are used to directly contact and squeeze the stone to enhance the crushing effect. The jaw plates are wearing parts and can be replaced.

[0010] In the present invention, the rear end face of the crushing plate is connected to a push rod and a guide column, both of which are slidably arranged in the base, and the guide column is used for sliding guidance; the push rod passes through the base and extends into the driving cavity in the center of the base, and a rotating driving disk assembly is arranged in the driving cavity, and the outer periphery of the driving disk assembly is petal-shaped. Under the action of the elastic reset device, the end of the push rod abuts against the outer periphery of the driving disk assembly, and is driven by the driving disk assembly to provide crushing pressure. When the driving disk assembly rotates, a continuous and variable driving force is formed, driving the push rod to reciprocate back and forth, thereby driving the crushing plate to squeeze and crush the stone.

[0011] Among them, the driving disc assembly is formed by stacking and connecting a plurality of single driving discs with staggered angles. The upper disc is ahead of the lower disc in angle, so that the push rod and crushing plate corresponding to the upper disc can be extended first, and the push rod and crushing plate corresponding to the lower disc can be extended later, so that coarse crushing can be completed first and then fine crushing can be carried out. The action sequence is ingenious and reasonable.

[0012] Furthermore, a universal ball is installed at the end of the push rod, and a slide groove adapted to the universal ball is provided on the outer periphery of the single driving disc. The universal ball abuts in the slide groove, which can ensure the stable transmission of the driving force.

[0013] In addition, in the crushing chamber, gathering plates are provided at both ends of each crushing plate, one end of the gathering plate is rotatably connected to the end of the partition plate, and the other end is provided with a strip-shaped slot hole, which is sleeved on the fixing pin at the end of the crushing plate. The gathering plate and the crushing plate form a linkage. When the crushing plate is pushed out, the gathering plates on both sides are driven to swing toward the center of the crushing chamber, so that the material holding space is contracted, which can reduce the material holding space and improve the ore crushing rate.

[0014] The upper and lower ends of the fixing pin are respectively fixed on the upper and lower end plates which are integral with the crushing plate. The end plates can cover the slots to prevent the crushed materials from entering the strip-shaped slots and blocking them, thereby affecting the activity of the gathering plate.

[0015] The crusher body described in the present invention is located below the ground, and the edge of the shell is flush with or lower than the ground, so that multiple forklifts or bulldozers can directly feed materials into the crusher body, thereby increasing the feed flow rate and improving the crushing efficiency; the materials can be directly received from the opening below the crusher body (i.e., the drop port) and transported away through the conveying device.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Optimize layout and reduce floor space: By designing the crusher body as a cylindrical shell and dividing the annular area between the base and the inner wall of the shell into multiple crushing units, the integrated design of the equipment is realized. This not only reduces the floor space of the equipment, but also makes the layout of the entire crushing production line more compact and reduces land use costs.

[0018] 2. Improve crushing efficiency: Multiple crushing units can feed and crush ore at the same time, making full use of the space in the annular area and greatly improving the crushing capacity. In addition, the crushing plates are arranged in a stepped manner, which can realize the step-by-step crushing of ore and further improve the crushing efficiency.

[0019] 3. Reduce management difficulty: The integrated design reduces the number of equipment and simplifies the structure of the production line, thereby reducing management difficulty. At the same time, due to the reduction in the number of equipment, the complexity of troubleshooting and maintenance is also reduced accordingly.

[0020] 4. Enhanced crushing effect: The jaw plates installed at the corresponding positions of the front end of the crushing plate and the inner wall of the shell, as well as the ingenious design of the push rod and the drive plate assembly, make the crushing process more stable and powerful, and enhance the crushing effect. In addition, the setting of the gathering plate enables the gathering plate and the crushing plate to form a linkage, so that the material space is closed during crushing, further improving the ore crushing rate.

[0021] 5. Increase feed flow: The main body of the crusher is located below the ground, and the edge of the shell is flush with or below the ground, so that multiple forklifts or bulldozers can directly feed materials into the main body of the crusher, greatly increasing the feed flow and further improving the crushing efficiency.

[0022] 6. Reduce safety hazards: By optimizing the layout and reducing the number of equipment, the safety hazards at the production site are reduced and the safety of production operations is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention is further described below in conjunction with specific embodiments.

[0042] However, the description of the present invention is merely an embodiment of structural and even functional description, and the scope of rights of the present invention is not limited by the embodiments described in the text.

[0043] For example, multiple embodiments may have various modifications and various forms, and it should be understood that the scope of rights of the present invention includes equivalents that can implement the technical concept.

[0044] This embodiment is implemented through the following technical solutions:

[0045] like Figures 1 to 4 As shown, the open-air large-scale ring-type integrated crushing system includes a crusher body 1, a frame 2 and a belt conveyor 3. The crusher body 1 is located below the ground and supported by the frame 2, and its edge is flush with the ground. The belt conveyor 3 is arranged on a slope, one end of which is located below the discharge port of the crusher body 1, and the other end is located on the ground.

[0046] like Figure 5 , 6 As shown, the crusher body 1 includes a shell 4, the upper part of the shell 4 is straight-cylindrical, the lower part is inverted-conical, and the top and bottom are open. The circular base 6 is located in the center of the shell 4, and the annular area between the base 6 and the inner wall of the shell 4 is divided into a plurality of crushing units 13, and the ore crushed by the crushing unit 13 is discharged from the bottom of the shell 4. Specifically, the annular area between the base 6 and the inner wall of the shell 4 is divided into a plurality of crushing chambers 5 by a plurality of partitions 14 distributed in a circumferential array, and each crushing unit 13 includes a crushing chamber 5 and three movable crushing plates therein, namely, an upper crushing plate 10, a middle crushing plate 11 and a lower crushing plate 12, and the upper, middle and lower three crushing plates are arranged in a stepped manner, and replaceable jaw plates are installed on the front end faces of all crushing plates and the positions corresponding to the crushing plates on the inner wall of the shell 4. Each crushing plate can move along the radial direction of the base 6, and can form an extrusion effect with the inner wall of the shell 4 to achieve step-by-step crushing of the ore.

[0047] like Figures 7-10 As shown, the rear end face of the crushing plate is connected to the push rod 17 and the guide column 18, and the push rod 17 and the guide column 18 are both slidably arranged in the base 6; the push rod 17 passes through the base 6 and extends into the driving cavity in the center of the base 6, and a rotating driving disk assembly 16 is arranged in the driving cavity, and the outer periphery of the driving disk assembly 16 is petal-shaped. Under the action of the elastic reset device 21, the end of the push rod 17 abuts against the outer periphery of the driving disk assembly 16. The driving disk assembly 16 is driven by a high-power motor 9 through a reducer 8 and a transmission shaft 15. The reducer 8 is installed on the dust cover 7 above the driving cavity, and the outer wall of the dust cover 7 is provided with a plurality of vertical strip-shaped heat sinks. When the driving disk assembly 16 rotates, a continuous and variable driving force is formed, which drives the push rod 17 to reciprocate back and forth, provides crushing pressure, and thus drives the crushing plate to squeeze and crush the stone.

[0048] Among them, the drive disc assembly 16 is composed of three single drive discs 23 stacked and connected at staggered angles. The upper disc is ahead of the lower disc in angle, so the push rod 17 and the crushing plate corresponding to the upper disc can be extended first, and the push rod 17 and the crushing plate corresponding to the lower disc can be extended later, so that coarse crushing can be completed first, and then fine crushing can be carried out. The action sequence is ingenious and reasonable, and the load of the high-power motor 9 can be more uniform without large fluctuations.

[0049] In addition, the end of the push rod 17 is connected to a hydraulic shaft 19, which is sleeved in the push rod 17. A hydraulic chamber is set between the hydraulic shaft 19 and the push rod 17, and the pressure relief valve 22 installed on the outer wall of the push rod 17 is connected to the hydraulic chamber inside the push rod 17. When an ore with too high hardness to be crushed appears in a certain crushing chamber 5, and the high-power motor 9 continues to run, the corresponding pressure relief valve 22 will be overloaded and opened, firstly to protect the equipment from damage, and secondly, it will not affect the operation of other crushing units, so that the crushing work can continue (at this time, no more material will be fed into the crushing unit, and the equipment will be shut down and re-pressurized into the hydraulic chamber, and it can be reused after maintenance). A universal ball 20 is installed at the end of the hydraulic shaft 19, and a slide groove 24 adapted to the universal ball 20 is provided on the outer periphery of the single drive disc 23. The universal ball 20 abuts in the slide groove 24 to ensure the stable transmission of the driving force.

[0050] like Fig.11 , 12As shown, in the crushing chamber 5, both ends of each crushing plate are provided with a gathering plate 25, one end of the gathering plate 25 is rotatably connected to the end of the partition plate 14, and the other end is provided with a strip-shaped slot 26, and the slot 26 is sleeved on the fixing pin 27 at the end of the crushing plate. The gathering plate 25 forms a linkage with the crushing plate. When the crushing plate is pushed out, the gathering plates 25 on both sides are driven to swing toward the center of the crushing chamber 5, so that the material storage space is closed, the material storage space can be reduced, and the ore crushing rate can be improved. Among them, the upper and lower ends of the fixing pin 27 are respectively fixed on the upper and lower end plates 28 that are integrated with the crushing plate, and the end plates 28 can cover the slot 26 to prevent the crushed material from entering the strip-shaped slot 26 and blocking it and affecting the movement of the gathering plate 25.

[0051] like Figures 13 to 17 As shown, the frame 2 supporting the crusher body 1 includes a plurality of columns 29, the bottom of the columns 29 is fixed by anchor bolts, and the tops of the plurality of columns 29 are connected by an arc-shaped ring beam 30. Since there is a construction gap between the ring beam 30 and the ground, a circle of connecting plates 32 is installed and laid between the ring beam 30 and the ground. In order to prevent the surrounding soil from collapsing, arc-shaped guard plates 33 are installed between adjacent columns 29. A forklift or bulldozer takes materials from a stone pile 34 on the side, and a guardrail 31 is installed above the ring beam 30. Without affecting the forklift or bulldozer from directly feeding materials into the crusher body 1, it plays a limiting role for the forklift or bulldozer, thereby improving the safety of the crushing site. Among them, the single column 29 and the single ring beam 30 are both made of I-beams; the vertical profiles at both ends of the single guardrail 31 are made of channel steel, and multiple steel bars are welded between the tops of the two channel steels; the single connecting plate 32 is made of patterned steel plate, and the single guard plate 33 is made of smooth steel plate. The above materials can be assembled and installed on site by bolt modularization.

[0052] Of course, the above contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the embodiments of the present invention. The present invention is not limited to the above examples, and equal changes and improvements made by ordinary technicians in the technical field within the essential scope of the present invention should all fall within the scope of the patent coverage of the present invention.
