Description

Technical Field

[0001] This application belongs to the field of ore separation technology, specifically an ore separation device for gold mine development. Background Technology

[0002] Ore separation equipment in gold mining is mainly used to separate larger and smaller ores. In practice, common methods include gravity separation, flotation, magnetic separation, electrostatic separation, and gravity separation. Gravity separation uses the density difference of the ore for physical separation; flotation separates the ore and other substances through the wet buoyancy difference in water; magnetic separation uses the magnetic differences of the ore to achieve separation; electrostatic separation uses the difference in conductivity of the ore to separate impurities; and gravity separation uses equipment such as shaking tables, spiral cyclones, and hydrocyclones to further separate the ore. In actual production, these methods are selected and combined according to factors such as ore properties, process requirements, and economic benefits to achieve efficient and accurate ore separation, improve ore recovery rate, and increase production efficiency.

[0003] For example, utility model patent CN219400574U discloses a primary ore separation device for gold mining, including a separation box. The top of the separation box has a feed inlet, the upper part of the separation box has a stirring mechanism, and the lower part of the stirring mechanism has a screen plate. The screen plate is inclined. The separation box has a discharge port along the inclined direction of the screen plate. The discharge port is located below the discharge port. The lower part of the separation box has an aeration mechanism located below the screen plate. The upper part of one side of the separation box has a foam outlet with a scraper mechanism. The separation box has a slidable push plate along the inclined direction of the screen plate. The push plate is threaded with a threaded rod that is consistent with the inclined direction of the screen plate. The two ends of the threaded rod are rotatably connected to the inner wall of the separation box. One end of the threaded rod extends out of the separation box and connects to the output end of a second motor. This utility model, through the setting of the second motor, threaded rod and push plate, can realize the removal of residual sludge on the screen plate, and the screen plate can be cleaned more conveniently in the later stage.

[0004] However, it was discovered during actual use that the device drives the scraper shaft to rotate via a third motor in the flotation ore separation method, thereby causing the scraper to rotate, which facilitates the scraping out of the coarse ore and foam floating on the surface.

[0005] However, when the multiple scrapers of this device rotate, a large amount of liquid is discharged from the separation tank. When too much liquid is discharged from the separation tank and the liquid level drops rapidly, it will affect the effective separation of coarse ore and foam. Therefore, an ore separation device for gold mine development is provided. Utility Model Content

[0006] The purpose of this application is to provide an ore separation device for gold mine development in order to solve the problems mentioned above.

A drain pipe is fixedly installed on one side of the collection shell.

[0010] In a preferred embodiment, a triangular support plate is fixedly installed on the outer surface of the aeration shell, and the bottom end of the triangular support plate is fixed to the top surface of the fixing plate.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0014] 1. In this application, due to the adoption of the above-mentioned scheme, the general-purpose motor drives the small pulley 2, the transmission belt 2, the large pulley 2, the stirring rod, and the stirring disc to rotate, thereby promoting the flow of water and flotation liquor in the ore separation shell, promoting the separation of coarse ore and slime. During the flotation process, bubbles attach the mineral particles to be separated to their surface to form a foam layer, and these foam layers float to the liquid surface. The coarse ore is carried by the bubbles to float to the liquid surface. Subsequently, the motor drives the reducer and the small pulley 1 to rotate. The small pulley 1 drives the large pulley 1 to rotate through the transmission belt 1, thereby facilitating the rotation of the rotating rod, scraper, and screen plate by the large pulley 1, discharging the foam and coarse ore floating on the liquid surface into the interior of the collection shell for collection. The rotating rod of this device drives the scraper and screen plate to rotate at a certain speed, which can effectively discharge the foam and coarse ore at the top of the ore separation shell, while not carrying out too much liquid, thus improving the ore separation efficiency.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

The bottom end of the triangular support plate 21 is fixed to the top surface of the fixing plate 2. An agitation mechanism 4 is set inside the ore separation shell 1 below the aeration shell 3. The aeration shell 3 facilitates the entry of subsequent gas, enabling the separation of coarse ore and sludge. The triangular support plate 21 facilitates the reinforcement of the aeration shell 3, improving its stability. The agitation mechanism 4 facilitates the mixing of flotation liquid and ore inside the ore separation shell 1, improving the separation efficiency.

[0022] refer to Figure 1 , Figure 2 and Figure 3 The stirring mechanism 4 includes a stirring rod 14, a stirring disc 15, a large pulley 16, a general-purpose motor 17, and a small pulley 18. The stirring rod 14 is rotatably connected inside the aeration shell 3. The bottom end of the stirring rod 14 extends to the bottom surface of the aeration shell 3. The stirring disc 15 is fixedly installed at the bottom end of the stirring rod 14, and the large pulley 16 is fixedly installed at the top end of the stirring rod 14.

Both the large pulley 16 and the small pulley 18 are fitted with transmission belts. The general-purpose motor 17 drives the small pulley 18. 18 rotates, which facilitates the rotation of the large pulley 2 16 driven by the transmission belt 2, so that the stirring rod 14 can drive the stirring disc 15 to rotate inside the ore separation shell 1. This allows the liquid inside the ore separation shell 1 to flow, which facilitates the separation of coarse ore and slime. During the flotation process, bubbles will attach the mineral particles to be separated to their surface, forming a foam layer. These foam layers will float to the surface of the liquid, and the coarse ore will be carried by the bubbles to float to the surface of the liquid, which facilitates the subsequent separation of coarse ore and discharge of foam. The stirring rod 14 is rotatably connected to the inside of the aeration shell 3 through the bearing seat, and both the top and bottom ends of the stirring rod 14 extend out.

Both the small pulley 13 and the large pulley 10 are fitted with a transmission belt. The motor 12 drives the reducer 11 to rotate. At this time, the reducer 11 drives the small pulley 13 to rotate. This facilitates the small pulley 13 to drive the large pulley 10 to rotate through the transmission belt, which is convenient for the subsequent discharge of foam and coarse ore inside the ore separation shell 1.

The general-purpose motor 17 drives the small pulley 18, the transmission belt 2, the large pulley 16, the stirring rod 14, and the stirring disc 15 to rotate, thereby promoting the flow of water and flotation liquor in the ore separation shell 1, promoting the separation of coarse ore and slime. During the flotation process, bubbles attach the mineral particles to be separated to their surface to form a foam layer, and these foam layers float to the surface of the liquid. The coarse ore is carried to the surface of the liquid by the bubbles. Subsequently, the operator starts... Motor 12 drives reducer 11 and small pulley 13 to rotate. Small pulley 13 drives large pulley 10 to rotate via transmission belt 1, which in turn drives rotating rod 7, scraper 8 and screen 9 to rotate.
