Description

Technical Field

[0001] This utility model relates to the field of ore crushing equipment, specifically to an integrated ore crushing and screening equipment. Background Technology

[0002] In the crushing of medium-hardness mineral samples, such as lead-zinc ore and copper ore, in industry laboratories of non-ferrous metal research institutions and universities, the raw materials need to be crushed and graded. When working indoors or in confined spaces, ungraded stone requires multiple crushing and screening operations using crushing and screening equipment of different specifications and apertures due to space limitations. This process is complex, uneven, time-consuming, labor-intensive, inefficient, and pollutes the environment, impacting project progress. Especially in lead-zinc ore crushing, due to its unique properties, it is difficult to crush and grind the ore quickly and effectively. The operation is time-consuming, labor-intensive, and yields poor crushing results, affecting grinding efficiency and experimental results.

[0003] A search revealed application CN202323096706.6, entitled "An Ore Crushing and Grinding Device." This application addresses the existing production process where ore crushing, grinding, and screening are performed using separate crushers, grinders, and screens or screening machines. Materials requiring grinding are then fed into the grinder, involving material transfer processes. This not only occupies a large area but is also inefficient. Furthermore, unsuitable materials screened out are re-sent to the crusher, resulting in cumbersome procedures and low efficiency. The proposed solution utilizes alloy toothed crushing rollers for rotary impact crushing of ore, achieving uniform, efficient, and continuous batch crushing. The crushed material is ground by a grinder within the crushing chamber, followed by precise sieving by a vibrating screen. The conical design at the bottom of the crushing chamber allows for gravity-based natural cascading screening, which can be adjusted according to… Adjusting the size, properties, and actual production requirements of the materials ensures processing accuracy and efficiency, enabling continuous crushing and screening. Finally, grinding pestles are used to grind the materials until they reach the required size of 0.02mm to 0.04mm, at which point they enter the hopper through mesh openings. Continuous grinding operations are possible, achieving integrated crushing, pulverizing, screening, and grinding. This eliminates the need for separate transfer equipment, reducing floor space and improving production efficiency. However, this application still uses a method of crushing first and then screening the ore, preventing simultaneous processing. Furthermore, ore that does not meet the particle size requirements after screening needs to be re-input for multiple crushing cycles, failing to meet the particle size requirements in one go. This reduces efficiency and increases structural complexity. Additionally, the need for a vibrating motor further complicates the structure, suggesting further improvements are possible.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an integrated ore crushing and screening equipment, which has the advantages of simple structure and high working efficiency, thereby solving the problems mentioned in the background technology.

[0006] To achieve the advantages of simple structure and high efficiency mentioned above, the specific technical solution adopted by this utility model is as follows:

[0007] An integrated ore crushing and screening device includes a base and a crushing and screening cylinder. A first frame and a second frame are fixedly installed on the top surface of the base, and the crushing and screening cylinder is installed between the first frame and the second frame. A drive motor is fixedly installed on the other side surface of the first frame. A flap is fixedly installed on the inner wall of the crushing and screening cylinder, and irregularly shaped metal blocks are placed inside the crushing and screening cylinder. Screen holes are opened on the outer wall of the crushing and screening cylinder. A feed pipe is fixedly connected through the surface of the second frame, and a feeding hopper is connected through the top opening of the feed pipe. The feed pipe passes through the other end of the crushing and screening cylinder and is rotatably connected to the other end of the crushing and screening cylinder.

[0008] Furthermore, the irregularly shaped metal blocks include pyramidal metal blocks, square metal blocks, and spherical metal blocks, and multiple sets of pyramidal metal blocks, square metal blocks, and spherical metal blocks are arranged.

[0009] Furthermore, the screen holes are distributed on the middle surface of the crushing and screening cylinder, and the screen holes are densely distributed at equal intervals.

[0010] Furthermore, the other end of the feed pipe is rotatably connected to the other end of the crushing and screening cylinder via a bearing, and the other end of the feed pipe is coaxially arranged with the crushing and screening cylinder.

[0011] Furthermore, the flaps are distributed on the inner wall surface of the crushing and screening cylinder, and multiple sets of flaps are distributed at equal angles along the central axis of the crushing and screening cylinder.

[0012] Furthermore, the crushing and screening cylinder has an overall spindle-shaped structure, and the inner walls at both ends of the crushing and screening cylinder are polished.

[0013] Furthermore, the size of the irregularly shaped metal block is larger than the size of the sieve aperture, and the size of the sieve aperture is equal to the target particle size of the ore.

[0014] Furthermore, the surface of the crushing and screening cylinder is provided with an inspection port, and an inspection plate is fixedly connected to the outside of the inspection port by fixing bolts.

[0015] Compared with the prior art, this utility model provides an integrated ore crushing and screening equipment, which has the following beneficial effects:

[0016] (1) This utility model adopts a crushing and screening cylinder. When crushing and screening ore, the ore can be fed into the feeding hopper after being initially crushed by a jaw crusher. The ore enters the crushing and screening cylinder along the feed pipe. The drive motor drives the crushing and screening cylinder to rotate, which in turn drives the flip plate to rotate and flip the ore. At the same time, the irregularly shaped metal blocks are flipped synchronously. The ore is crushed by the collision between the irregularly shaped metal blocks and the ore and the collision between the ores. The ore that meets the particle size requirements passes through the screen holes and is discharged, completing the process of crushing and screening at the same time until the ore is completely crushed to the target particle size. Compared with the traditional equipment that crushes first and then screens, this device crushes and screens at the same time, without the need for repeated feeding and repeated crushing, which improves the working efficiency and the convenience of use. At the same time, the irregularly shaped metal blocks include pyramidal metal blocks, square metal blocks and spherical metal blocks. The collision between the pyramidal metal blocks and the square metal blocks and the ore improves the crushing efficiency of the ore and further improves the crushing effect.

[0017] (2) This utility model uses irregularly shaped metal blocks. During the process of turning and colliding with the ore, the irregularly shaped metal blocks generate high-frequency irregular vibrations. The generated high-frequency irregular vibrations can effectively shake out the ore blocked inside the screen holes, thereby avoiding the phenomenon of blockage. Compared with the traditional screening mechanism, it saves the trouble of using a vibrating motor for vibrating screening, further improving work efficiency and the simplicity of the structure.

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, an integrated ore crushing and screening device is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, an integrated ore crushing and screening device according to an embodiment of this utility model comprises a base 1 and a crushing and screening cylinder 4. The components work together to achieve the innovative function of simultaneous crushing and screening. The base 1, serving as the fundamental support structure of the entire device, is cast from high-strength cast steel and strengthened through a special heat treatment process, possessing excellent compressive and seismic resistance, capable of stably bearing the enormous load generated during equipment operation. On the top surface of the base 1, a first upright 2 and a second upright 10 are fixedly installed through high-precision machining and assembly processes. The first upright 2 and the second upright 10 are arranged parallel and opposite to each other, and both are perpendicular to the base 1. This strict vertical and parallel design, based on rigorous mechanical analysis, ensures the stability of the equipment during operation. To ensure stability and effectively avoid vibration and displacement caused by installation errors, the core working component of the equipment, the crushing and screening cylinder 4, is supported between the first frame 2 and the second frame 10. The crushing and screening cylinder 4 is arranged horizontally, which conforms to the process flow of ore processing and facilitates material flow and handling. A drive motor 3 is fixedly installed on the other side of the first frame 2. The drive motor 3 is a high-power, high-torque industrial-grade motor, and its output end is fixedly connected to the center of one end of the crushing and screening cylinder 4 through a high-strength coupling. This common and mature drive form can efficiently and stably transmit power to the crushing and screening cylinder 4, ensuring the reliability of equipment operation. A flap 5 is fixedly installed on the inner wall of the crushing and screening cylinder 4. The flap 5 is made of wear-resistant alloy material. Its surface undergoes a special hardening treatment, possessing extremely high wear resistance and impact resistance. The main function of the flap 5 is to powerfully agitate the irregularly shaped metal blocks 11 and ore during the rotation of the crushing and screening cylinder 4, causing them to continuously tumble and collide inside the crushing and screening cylinder 4, creating favorable conditions for ore crushing. The crushing and screening cylinder 4 contains irregularly shaped metal blocks 11, which are key elements for achieving efficient crushing. Furthermore, the outer wall of the crushing and screening cylinder 4 is provided with screen holes 6, the design of which directly affects the screening effect and efficiency. The surface of the second vertical frame 10 is fixedly connected to a feed pipe 9, which is made of high-quality seamless steel pipe, possessing good wear resistance and corrosion resistance. The top opening of the feed pipe 9 is connected to a feeding hopper 8. Designed with a large opening and funnel-shaped structure, it facilitates rapid ore input and reduces manual operation difficulty. The feed pipe 9 passes through and rotatably connects to the other end of the crushing and screening cylinder 4. In actual operation, when crushing and screening ore, the ore is first initially crushed by a jaw crusher. This step effectively reduces the initial particle size of the ore, facilitating subsequent processing in this equipment. The initially crushed ore is fed into the feeding hopper 8, and then, relying on its own gravity, smoothly enters the crushing and screening cylinder 4 along with the feed pipe 9. Subsequently, the drive motor 3 starts, driving the crushing and screening cylinder 4 to rotate, simultaneously rotating the tilting plate 5. During the rotation, the tilting plate 5 tilts the ore, and at the same time, the irregularly shaped metal block 11 is also tilted synchronously.The ore is crushed through intense collisions between the irregularly shaped metal blocks 11 and the ore, as well as through collisions between the ore particles themselves. Ore that meets the particle size requirements passes through the screen holes 6 under the influence of gravity and centrifugal force, thus completing the process of simultaneous crushing and screening until the ore is completely crushed to the target particle size. Compared to traditional equipment that crushes first and then screens, this device breaks with conventional processes, performing crushing and screening simultaneously without the need for repeated feeding and crushing. This significantly shortens ore processing time and greatly improves work efficiency and ease of use. Furthermore, the irregularly shaped metal blocks 11 include pyramidal, square, and spherical metal blocks. The edges of the pyramidal and square metal blocks generate powerful impact and shear forces when colliding with the ore, effectively improving the crushing efficiency and further enhancing the crushing effect.

[0028] In one embodiment, the irregularly shaped metal blocks 11 include pyramidal metal blocks, square metal blocks, and spherical metal blocks, and multiple sets of these three types of metal blocks are arranged. During the rotation of the crushing and screening cylinder 4, the irregularly shaped metal blocks 11 generate high-frequency irregular vibrations due to their different shapes and uneven mass distribution during the tumbling and collision with the ore. This unique vibration mode can effectively shake out the ore blocked inside the screen holes 6, thereby avoiding the phenomenon of blockage. Compared with the traditional screening mechanism, this equipment does not require the use of an additional vibration motor for vibration screening, which simplifies the equipment structure, reduces equipment costs and maintenance workload, further improves work efficiency, and also enhances the simplicity and reliability of the structure.

[0029] In one embodiment, the screen holes 6 are distributed on the middle surface of the crushing and screening cylinder 4, and the screen holes 6 are densely distributed at equal intervals. This carefully designed screen hole layout 6 has been verified by a large number of experiments and data analysis, which can significantly improve screening efficiency and uniformity of output. At the same time, the densely distributed screen holes 6 can, to a certain extent, avoid the situation of screening interruption caused by the clogging and failure of some screen holes 6, and ensure that the equipment can operate continuously and stably.

[0030] In one embodiment, the other end of the feed pipe 9 is rotatably connected to the other end of the crushing and screening cylinder 4 via a high-precision bearing 7. This connection method can effectively reduce friction during rotation and stabilize the rotation of the crushing and screening cylinder 4. Furthermore, the other end of the feed pipe 9 is coaxially arranged with the crushing and screening cylinder 4, and the crushing and screening cylinder 4 is also coaxially arranged with the drive motor 3. This strict coaxial design, based on precise machining and assembly processes, can greatly improve the stability of rotation, reduce vibration and noise during equipment operation, and extend the service life of the equipment.

[0031] In one embodiment, the flaps 5 are distributed on the inner wall surface of the crushing and screening cylinder 4, and multiple sets of flaps 5 are distributed at equal angles along the central axis of the crushing and screening cylinder 4. This uniform distribution design can ensure that the ore and irregular metal blocks 11 are flipped more evenly during the rotation of the crushing and screening cylinder 4, thereby improving work efficiency and ensuring the consistency of crushing and screening effect.

[0032] In one embodiment, the crushing and screening cylinder 4 has an overall spindle-shaped structure. This unique shape design is not arbitrary, but rather a result of comprehensive consideration of fluid mechanics and mechanical kinematics. The inner walls at both ends of the crushing and screening cylinder 4 are polished. The smooth inner walls can effectively reduce the accumulation of ore at the ends, making it easier for ore and irregularly shaped metal blocks 11 to be concentrated in the middle of the crushing and screening cylinder 4 for crushing. This optimizes the movement trajectory of the material and improves the crushing efficiency.

[0033] In one embodiment, the size of the irregular metal block 11 is larger than the size of the screen hole 6, and the size of the screen hole 6 is equal to the target particle size of the ore. The size of the irregular metal block 11 is smaller than the distance between the flaps 5. This precise size design ensures that the irregular metal block 11 will not leak out of the screen hole 6, and can smoothly enter between the flaps 5, ensuring the normal operation of the crushing and screening process.

[0034] In one embodiment, an inspection port 14 is provided on the surface of the crushing and screening cylinder 4. The location of the inspection port 14 is reasonably planned to facilitate the staff to inspect and maintain the inside of the equipment. An inspection plate 12 is fixedly connected to the outside of the inspection port 14 by fixing bolts 13. When the equipment needs maintenance and repair, the staff only needs to use the corresponding tools to unscrew the fixing bolts 13 to open the inspection plate 12, so as to conveniently and quickly inspect, replace and repair the internal components of the equipment.

[0035] Working principle:

[0036] The specific process for crushing and screening ore is as follows: First, the mined ore is transported to a jaw crusher for preliminary crushing to reduce the particle size to a range suitable for the equipment. The pre-crushed ore is then transported to the feeding hopper 8. The ore, under its own gravity, smoothly enters the crushing and screening cylinder 4 along the feed pipe 9. After the drive motor 3 starts, it transmits power to the crushing and screening cylinder 4 through a coupling, causing the cylinder to rotate. Simultaneously, the flaps 5 installed on the inner wall of the crushing and screening cylinder 4 also rotate. During rotation, the flaps 5 continuously agitate the ore and irregularly shaped metal blocks 11, causing frequent and intense collisions between the irregularly shaped metal blocks 11 and the ore, and between the ore blocks themselves. The edges of the pyramidal and square metal blocks generate strong impact and shear forces on the ore during these collisions, gradually crushing it. Simultaneously, ore meeting the particle size requirements is further crushed under gravity. Under the combined action of centrifugal force, the ore passes through the screen hole 6 and is discharged from the equipment, completing the screening process. The ore that does not reach the target particle size continues to be further crushed in the crushing and screening cylinder 4. During this process, the high-frequency irregular vibration generated by the shaped metal block 11 when it is tumbling and colliding with the ore can promptly shake out the ore that is blocked inside the screen hole 6, ensuring that the screen hole 6 is unobstructed and maintaining the smooth progress of the screening process until the ore is completely crushed to the target particle size, completing the entire crushing and screening work. Compared with the traditional equipment that crushes first and then screens, this device realizes the simultaneous operation of crushing and screening, avoiding the cumbersome process of repeated feeding and repeated crushing, greatly improving work efficiency, simplifying the process flow, and reducing equipment operating costs and maintenance difficulty. In addition, the unique design of the shaped metal block 11 and the layout of the screen hole 6 further improve the crushing effect and screening efficiency, giving the equipment a significant performance advantage.
