Description

Technical Field

[0001] This utility model relates to the field of mining crusher technology, specifically a crushing device used in the mining of gold concentrate. Background Technology

[0002] Gold concentrate refers to the portion of gold-bearing ore with a high gold content. Typically, after mining and initial processing, these ores undergo further refining to extract the gold. The concentrate usually undergoes a series of processes, such as crushing, grinding, flotation, gravity separation, or cyanidation, to increase the gold concentration and purity.

[0003] Chinese utility model patent, authorized announcement number CN215612277U, discloses a crusher for mining, including a crusher body, a crushing shaft, and a water supply pipe. When the crushing is being performed, the water supply pipe sends water into the rotating plate. As the water flows through the water supply pipe, it pushes the blades to drive the rotating shaft to rotate. The rotating shaft drives the rotating plate to rotate around the water supply pipe. Various water spray holes spray the water supplied by the water supply pipe out of the rotating plate in a rotating manner. By spraying water through the rotating plate, the contact area between the water and the stone being crushed by the crushing shaft is larger, resulting in a better dust reduction effect.

[0004] This device reduces dust by spraying water into the crusher body. In the process of gold ore mining, ore needs to be continuously transported out of the mine. However, the volume of mined gold ore is generally large, and direct transportation is not convenient. Therefore, it is usually necessary to crush the gold ore to be transported out first to reduce its volume for easier transportation. During the crushing process, some ore has been crushed into standard particle size. If this part of the ore participates in the secondary crushing in the later stage, it will inevitably reduce the production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a crushing device used in the mining of gold concentrate to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crushing device used in the mining of gold concentrate, comprising a crusher shell and a feed hopper, wherein two crushing rollers are provided on the top of the crusher shell to perform preliminary crushing of gold ore, and a triangular block is fixed at the bottom of the crusher shell, wherein two inclined hollow plates are fixed at the bottom of the triangular block, and the bottom of the inclined hollow plates forms an arc-shaped hollow plate.

[0007] An arc-shaped collecting plate is placed directly below the triangular block;

[0008] A discharge port is formed between the inclined hollow plate and the side wall of the crusher shell, and a conveying mechanism is placed directly below the discharge port.

[0009] Top water pipes are fixed on both sides of the top of the triangular block, and several first nozzles are fixedly connected to the pipe body of the top water pipes.

[0010] The top of the arc-shaped collection plate is equipped with multiple bottom water pipes, and multiple second nozzles are fixedly connected to the pipe body of the bottom water pipes.

[0011] Preferably, a baffle is fixed to the top of each of the two crushing rollers, and the extension lines of the two baffles are V-shaped.

[0012] Preferably, a buffer block made of rubber material is connected to the middle of the triangular block.

[0013] Preferably, the arc-shaped collecting plate includes a base plate and a guide plate, with the guide plate fixed to the top of the base plate;

[0014] The thickness of the guide plate gradually decreases along the conveying direction of the conveying mechanism.

[0015] Preferably, the angle between the second nozzle and the base plate is 30-70 degrees.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The crushing device used in the gold concentrate mining process is equipped with a top water pipe and a first nozzle. The water sprayed from the first nozzle can wash the ore blocks falling along both sides of the triangular block, thereby achieving dust reduction while washing the crushed gold ore.

[0018] Meanwhile, a system consisting of a second water pipe, a second nozzle, an inclined perforated plate, and an arc-shaped perforated plate is installed. Crushed ore that meets the requirements for direct smelting falls to the top of the bottom plate through the inclined and arc-shaped perforated plates. In addition, since the arc-shaped perforated plate can block the water flow, the debris and dust generated by the scouring also fall to the top of the bottom plate through the inclined perforated plate. The second nozzle obliquely scours the guide plate, thereby flushing the crushed gold ore that meets the smelting requirements away from the bottom plate and collecting it, avoiding its re-participation in subsequent secondary crushing and improving production efficiency.

[0019] In addition, a buffer block made of rubber is connected to the middle of the triangular block. The crushed ore falls to the top of the triangular block through the gap between the two crushing rollers. The buffer block can buffer the downward impact force, thereby reducing the vibration during the operation of the crushing device, reducing the noise generated by the machine, and further improving the practicality of the device.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The crushing device in this solution is specifically designed for the preliminary crushing of large blocks of ore during the mining of refined gold, reducing their volume to facilitate their transport out of the mine.

[0027] like Figures 1-4 As shown, this utility model provides a technical solution: a crushing device used in the mining of gold concentrate, including a crusher shell 1 and a feed hopper 101 connected to the inner cavity of the crusher shell 1. Two crushing rollers 2 are arranged on the top of the crusher shell 1, and baffles 3 are fixed on the top of each of the two crushing rollers 2. The extension lines of the two baffles 3 are V-shaped. In this way, when feeding, the baffles 3 can not only buffer the gold ore to reduce the impact force between the ore and the crushing rollers 2, thereby protecting the crushing rollers 2, but also prevent the ore from entering the gap between the crushing rollers 2 and the top wall of the crusher shell 1. To prevent the crushing device from jamming, it is known that the two crushing rollers 2 are driven by a drive motor. The relative rotation of the crushing rollers 2 achieves the initial crushing of gold ore. A triangular block 401 is fixed at the bottom of the crusher housing 1. The cross-section of the triangular block 401 is triangular, and its top is formed with an arc-shaped chamfer. Two inclined hollow plates 402 are fixed at the bottom of the triangular block 401. An arc-shaped hollow plate 403 is formed at the bottom of the inclined hollow plate 402. The material leakage holes opened on the inclined hollow plate 402 and the arc-shaped hollow plate 403 can filter the gold ore fragments produced by crushing that are suitable for direct smelting.

[0028] In this plan, such as Figure 2As shown, a buffer block 404 made of rubber material is connected to the middle of the triangular block 401. That is, the triangular block 401 is divided into two parts, and the buffer block 404 is fixed between the two triangular blocks 401. In this way, the crushed ore falls to the top of the triangular block 401 through the gap between the two crushing rollers 2. The buffer block 404 can buffer the downward impact force, thereby reducing the vibration during the operation of the crushing device and reducing the noise generated by the machine.

[0029] An arc-shaped collecting plate 7 is placed directly below the triangular block 401. The arc-shaped collecting plate 7 includes a base plate 701 and a guide plate 702. The guide plate 702 is fixed to the top of the base plate 701. The upper extension plates on both sides of the guide plate 702 are fixed to the bottom of two arc-shaped hollow plates 403 respectively. The guide plate 702 is used to carry the gold ore fragments that are suitable for direct smelting after being filtered by the inclined hollow plate 402 and the arc-shaped hollow plate 403.

[0030] A discharge port 5 is formed between the inclined perforated plate 402 and the side wall of the crusher housing 1. A conveying mechanism 6 for transporting gold ore is placed directly below the discharge port 5. The conveyor belt of the conveying mechanism 6 can be a rubber belt or a metal belt.

[0031] Top water pipes 8 are fixed on both sides of the top of the triangular block 401. Several first nozzles are fixedly connected to the pipe body of the top water pipes 8. The water sprayed from the first nozzles can clean the ore blocks falling along both sides of the triangular block 401, thereby achieving dust reduction and cleaning the broken gold ore at the same time.

[0032] The top of the arc-shaped collection plate 7 is provided with multiple bottom water pipes 9, and multiple second nozzles 901 are fixedly connected to the pipe body of the bottom water pipes 9, such as... Figure 3 As shown, the angle between the second nozzle 901 and the base plate 701 is 30-70 degrees. This is to facilitate the removal of the crushed gold ore from the guide plate 702. Figure 4 As shown, in this scheme, the thickness of the guide plate 702 gradually decreases along the conveying direction of the conveying mechanism 6.

[0033] The top water pipe 8 and the bottom water pipe 9 can be connected to their respective water pumps and water sources, or a water storage tank can be set up on the ground. The top water pipe 8 and the bottom water pipe 9 are connected through a main water pipe, which is connected to the water storage tank. A water pump is connected to the main water pipe, and the water in the water storage tank is pumped to the first nozzle and the second nozzle 901 respectively.

[0034] As a supplement to this scheme, gold ore is fed into the feed hopper 101, and two crushing rollers 2 perform preliminary crushing on the ore. The crushed ore falls to the top of the triangular block 401 and then falls along both sides of the triangular block 401. During the fall, the water flow sprayed from the first nozzle washes the ore. The crushed ore that is suitable for direct smelting falls to the top of the bottom plate 701 through the inclined perforated plate 402 and the arc-shaped perforated plate 403. In addition, since the arc-shaped perforated plate 403 can block the water flow, the debris and dust generated by the scouring also fall to the top of the bottom plate 701 through the inclined perforated plate 402. The second nozzle 901 obliquely scours the guide plate 702, thereby flushing the crushed gold ore away from the bottom plate 701 and collecting it.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
