Description

Technical Field

[0001] This utility model relates to the field of waste rock treatment machinery technology, specifically a comprehensive recycling and treatment equipment for waste rock from metal mining. Background Technology

[0002] During the mining process of metal mines, a large amount of waste rock (such as surrounding rock, low-grade ore, etc.) is generated. These waste rocks usually contain a small amount of valuable metals or recyclable minerals. However, due to the low efficiency of traditional treatment methods (such as stockpiling and landfilling) and the ease with which they cause resource waste and environmental pollution, there is an urgent need for efficient and environmentally friendly resource recycling technologies.

[0003] A search revealed a utility model patent with patent authorization announcement number CN222586696U, which discloses a pretreatment equipment for mining waste rock recycling, including a crushing device, a screening device, and a sorting device. The discharge port A of the crushing device corresponds to the feed port B of the screening device. The drum screen in the screening device is equipped with a primary screen, a secondary screen, and a tertiary screen, which can screen fine particles, coarse particles, from left to right. The corresponding discharge port B is provided below each level of screen.

[0004] Currently, waste rock resource utilization typically employs processes such as crushing, grinding, and sorting. Traditional crushing equipment, such as jaw crushers and cone crushers, can achieve coarse crushing, but it is difficult to flexibly adjust the crushed particle size, resulting in low subsequent sorting efficiency. At the same time, traditional crushing equipment lacks supporting cleaning functions, and impurities adhering to the ore surface can affect the sorting accuracy. Utility Model Content

[0005] The purpose of this utility model is to provide a comprehensive recycling and processing equipment for waste rock from metal mining, which solves the problem that traditional crushing equipment is difficult to adjust the crushing particle size flexibly, and also solves the problem that traditional crushing equipment lacks a matching cleaning function, and that impurities attached to the ore surface will affect the sorting accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a comprehensive recycling and processing equipment for waste rock from metal mining, comprising a machine compartment, a grinding seat fixedly connected to the inner side of the upper opening of the machine compartment, two supports fixedly connected to the upper outer side of the machine compartment, a support base fixedly connected between the two supports, and the support base located above the machine compartment, a motor fixedly installed at the middle of the upper end of the support base, the output shaft of the motor passing through the support base and connected to the support base via a bearing, a polygonal shaft fixedly connected to the end of the output shaft, a bushing slidably sleeved on the outer side of the polygonal shaft, a crushing seat fixedly connected to the bottom of the bushing, the crushing seat located inside the grinding seat, a gap being left between the crushing seat and the grinding seat, and an adjustment mechanism provided on the outer side of the bushing.

[0007] Preferably, a fixing rod is fixedly connected to the bottom of the grinding seat, and a ring pipe is fixedly connected to the bottom of the fixing rod. A nozzle is provided on the inner wall of the ring pipe, and a water inlet pipe is connected to the outer wall of the ring pipe. The water inlet pipe passes through the machine compartment and extends to the outside of the machine compartment. After the water inlet pipe is connected to a high-pressure water source through a connecting hose, water can be injected into the ring pipe and then sprayed out through the nozzle, thus cleaning the crushed stone.

[0008] Preferably, a connecting rod is fixedly connected to the bottom of the pulverizing seat, a support rod is fixedly connected to the lower section of the connecting rod, and a protective ring net is fixedly connected to the end of the support rod. The protective ring net is located inside the ring tube, and its position corresponds to the position of the nozzle. The protective ring net provides protection for the nozzle.

[0009] Preferably, a guide sleeve is fixedly connected to the bottom of the grinding base, and the protective ring mesh is located inside the guide sleeve. The guide sleeve helps to separate the gap between the protective ring mesh and the grinding base, preventing gravel from spilling out to the nozzle.

[0010] Preferably, the adjusting mechanism includes a linkage seat fixedly connected to the upper outer side of the bushing. Two U-shaped pins are rotatably connected inside the linkage seat. A hydraulic cylinder is fixedly installed on the upper left side of the support seat. The telescopic shaft of the hydraulic cylinder passes through the support seat and is slidably connected to it. The end of the telescopic shaft is fixedly connected to the U-shaped pins on the left side. By setting up the adjusting mechanism, the axial position of the bushing on the polygonal shaft can be adjusted, thereby adjusting the gap between the crushing seat and the grinding seat, achieving the purpose of multi-stage crushing of waste ore.

[0011] Preferably, a guide post is fixedly connected to the top of the convex pin on the right side. The guide post passes through the support base and is slidably connected to the support base. The guide post guides and balances the force on the linkage seat during lifting and lowering.

[0012] Preferably, the exterior of the cabin is welded with multiple support legs, which are arranged in a circular array. These support legs provide structural support.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model adjusts the gap between the crushing seat and the grinding seat through an adjustment mechanism to meet the crushing requirements of waste rock of different particle sizes. Specifically, the hydraulic cylinder drives the convex pin to move the bushing up and down along the polygonal shaft, thereby precisely controlling the distance between the crushing seat and the grinding seat. This multi-level adjustment function can adapt to the differences in ore hardness and particle size, and can both coarsely crush large pieces of waste rock and finely grind them to the target particle size, significantly improving the resource recovery rate.

[0015] 2. This utility model features a ring tube fixed to the bottom of the grinding base by a fixing rod. The outer ring of the ring tube has a water inlet pipe extending to the outside of the machine chamber, while the inner ring of the ring tube has a nozzle. When the water inlet pipe is connected to a high-pressure water source, water can be injected into the ring tube and then sprayed out through the nozzle. This process can clean the crushed stone, and the water flow can effectively remove clay and impurities from the surface of the ore, providing clean raw materials for subsequent sorting and reducing metal loss.

[0024] Please see Figures 1-3An adjustment mechanism 8 is provided on the outer side of the bushing 6. This mechanism adjusts the axial position of the bushing 6 on the polygonal shaft 5, thereby adjusting the gap between the crushing seat 7 and the grinding seat 101 to achieve multi-stage crushing of waste ore.

[0025] The specific implementation process of this utility model is as follows: In use, the motor 4 is started first, and the motor 4 drives the polygonal shaft 5 to rotate. The polygonal shaft 5 drives the crushing seat 7 to rotate through the cooperation with the bushing 6. Then, the water inlet pipe 11 is connected to the high-pressure water source through the pipeline. Then, the waste ore is put into the machine chamber 1 from the top. The waste ore is crushed between the crushing seat 7 and the grinding seat 101. Then, it is cleaned by the spray nozzle 12 on the ring pipe 10 spraying clean water. The water flow can effectively remove clay and impurities from the surface of the ore, providing clean raw materials for subsequent sorting and reducing metal loss. In addition, the hydraulic cylinder 83 drives the convex pin 82 to drive the bushing 6 to slide up and down along the polygonal shaft 5, thereby precisely controlling the distance between the crushing seat 7 and the grinding seat 101. This multi-level adjustment function can adapt to the differences in ore hardness and particle size. It can coarsely crush large pieces of waste ore and finely grind them to the target particle size, significantly improving the resource recovery rate.
