Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ore crushing, in particular to a non-ferrous metal ore crushing processing device. BACKGROUND

[0002] Mine stones are important materials indispensable to the construction industry, which also include many non-ferrous metal ores. In the mining and recycling of mine stones, in order to facilitate the transportation of ores, a crushing device is needed to crush large ores into smaller ones.

[0003] The current crushing device mainly includes a jaw crusher, a hammer crusher, an impact crusher and a roller crusher, etc. The ores fall into the device through the feeding port at the top of the device, and the ores are crushed by the jaw friction, hammer impact or roller stirring force, so as to realize the crushing of the ores. The finished ores leak out from the bottom of the crushing device to achieve the purpose of crushing the ores.

[0004] In order to ensure the crushing effect, the current ore crushing device usually adopts different crushing devices for crushing according to different ore raw materials. For example, different crushing devices are needed for non-ferrous metal ores with different hardness. However, the existing crushing device is usually limited to a single crushing form, such as jaw type and hammer type. The conventional operation is to connect any multiple crushing devices through a conveyor belt, which greatly increases the energy consumption of the device during the crushing process and increases the cost of ore crushing.

[0010] Further, the first crushing assembly comprises an outer wall connected to the top of the stabilizing support, a lower hopper extending outward from the side of the outer wall away from the stabilizing support, a fixed crushing wall fixedly arranged on the inner side of the outer wall close to the side of the second crushing assembly, a movable crushing piece movably arranged on the inner side of the outer wall away from the fixed crushing wall, and a conveying belt embedded in the discharge port.

[0032] In specific implementation, first, the operator can introduce non-ferrous metal ore into the outer wall 11 between the movable crushing wall 17 and the fixed crushing wall 13 along the feeding hopper 12, and then open the output shaft 15. In some optional embodiments of the present application, the output shaft 15 is connected with a motor in the axial direction. The motor can be arranged opposite to the output shaft 15 in the axial direction of the outer wall 11. In addition, the non-ferrous metal ore crushing device of the present application is also provided with a controller. The controller can be arranged at any position on the non-ferrous metal ore crushing device which is convenient for the operator to operate. The controller can be an MCU (Microcontroller Unit) chip to control the whole non-ferrous metal ore crushing device. The controller is electrically connected with the non-ferrous metal ore crushing device, and the electrical connection includes wired connection and wireless connection. The wireless connection includes but is not limited to Bluetooth connection, WiFi, IF radio frequency, zigbee, and the wired connection includes but is not limited to USB line connecting the non-ferrous metal ore crushing device with the controller. Then, when the operator controls the motor to drive the output shaft 15 to rotate, the output shaft 15 drives the eccentric shaft 16 connected with it in the axial direction to rotate eccentrically. In some optional embodiments, the output shaft 15 and the eccentric shaft 16 can be connected through a double-shaft support 331, or connected through at least one bearing at any position deviating from the center of the output shaft 15 and the eccentric shaft 16, so that the output shaft 15 is driven by the eccentric shaft 16 to move the movable crushing wall 17 vertically to the ground track during rotation. In addition, the stabilizing piece 18 arranged at the bottom of the movable crushing wall 17 supports the bottom of the movable crushing wall 17, so that the originally vertical movable crushing wall 17 inclines to the side of the fixed crushing wall 13, and moves towards or away from the fixed crushing wall 13, and preliminarily crushes the non-ferrous metal ore in the middle by extruding and rubbing. When the volume of the ore is smaller than the space below the conical guide hole, the ore can be introduced onto the surface of the conveyor belt 110 below, and the conveyor belt 110 introduces the preliminarily crushed ore into the secondary crushing assembly 3 for multi-stage crushing. Specifically, first, the operator can control the driving motor 4 to open through the controller, and the driving motor 4 drives the driving gear 323 to rotate. During the process, the driving gear 323 drives the crushing disc 332 to rotate along the stabilizing shaft 321 in the axial direction. At the same time, the driving gear 323 drives the upper first eccentric crushing piece 32 to rotate, and the first eccentric crushing piece 32 drives the upper double-shaft support 331, the crushing disc 332 and the crushing wall 333 in turn to rotate. During the rotation, the second eccentric crushing piece 33 and the first eccentric crushing piece 32 do not rotate around the same center, which can be understood by those skilled in the art. The principle can refer to the above-mentioned eccentric shaft 16. At the same time, one driving motor 4 can be used to drive two crushing pieces to perform double crushing operation.

[0033] Further, when the initially crushed ore is introduced into the secondary crushing assembly 3, a first stage crushing operation is first performed by the second eccentric crushing piece 33. In order to improve the stability of the crushing disc 332 and the crushing wall 333, a limiting groove 313 is provided on the top of the crushing cylinder 31 for accommodating part of the second eccentric crushing piece 33. When the ore falls into the area of the second eccentric crushing piece 33, the ore between them can be crushed by the movement track of the second eccentric crushing piece 33 adhering to the inner wall of the crushing cylinder 31. In addition, in order to avoid the situation that a large amount of ore simultaneously flows into the crushing cylinder 31, which easily causes device jamming and reduces the crushing efficiency, the second eccentric crushing piece 33 can effectively isolate part of the ore from entering the first eccentric crushing piece 32 below. While the second eccentric crushing piece 33 is rotating and crushing the ore, it also controls the discharging of the ore. It can be understood that when the second eccentric crushing piece 33 rotates to one side, the other side is empty, and the ore can fall into the first eccentric crushing piece 32 along the other side. At the same time, the second eccentric crushing piece 33 is always in a state of movement, and the ore on its top affected by the centripetal force will also be thrown into the first eccentric crushing piece 32 below after staying. In some optional embodiments, in order to avoid the splashing of the ore, a conical discharging hopper similar to the discharging hopper 12 can be added at the top of the crushing cylinder 31 to cooperate with the discharging.

[0034] Subsequently, the ore crushed by the second eccentric crushing piece 33 falls into the covered area of the first eccentric crushing piece 32 to perform the second stage crushing. Specifically, due to the limited size of the ore, the ore that does not meet the size requirement will be intercepted between the crushing cone 325 and the arc-shaped crushing wall 311, and will be crushed by the crushing cone 325 along the trajectory of the arc-shaped crushing wall 311. The crushing cone 325, due to the eccentricity of the eccentric seat 324, changes the original axial rotation trajectory along the stable shaft 321 to eccentric rotation towards the arc-shaped crushing wall 311, thereby implementing the second stage crushing of the ore between the arc-shaped crushing wall 311 and the crushing cylinder 31. Then, the ore that meets the size requirement can be guided out through the discharge slot 314 to complete the final ore crushing operation.

[0035] In summary, after the ore is initially crushed by the primary crushing assembly 1, the driving motor 4 can be turned on to drive the first eccentric crushing piece 32 to rotate, and the first eccentric crushing piece 32 can in turn drive the upper double-shaft support 331 and the second eccentric crushing piece 33 to rotate. During the rotation, the second eccentric crushing piece 33 and the first eccentric crushing piece 32 do not rotate around the same center, and the double crushing operation can be performed by one driving motor 4, which solves the problem of connecting multiple crushing devices by a conveyor belt, greatly increasing the energy consumption of the crushing device and the cost of ore crushing.
