Description

Technical Field

[0001] This utility model relates to the field of mineral slurry treatment technology, specifically to a mineral slurry sorting tank. Background Technology

[0002] In mineral slurry sorting operations, improving the recovery rate of target minerals is one of the core requirements. However, traditional sorting equipment generally suffers from low recovery rates due to structural design defects.

[0003] On the one hand, traditional equipment mostly adopts a single stirring and foaming separation structure, which only uses a stirring rod to drive the slurry and reagents to mix and form foam. The minerals are separated by relying on the natural floating of the foam. It lacks precise control of the separation process and secondary capture design. When the slurry is stirred and overflows, some residual foam that has not been completely separated is often carried in the overflow slurry. Traditional equipment does not have a special interception structure, which causes this residual foam to be discharged directly with the overflow slurry, resulting in the loss of target minerals and low slurry separation recovery rate. Therefore, a slurry separation tank is provided to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a slurry sorting tank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A slurry sorting tank includes a tank body, within which a stirring chamber and a transfer chamber are provided. An overflow port connects the stirring chamber and the transfer chamber. A support plate A is welded and fixedly installed above the stirring chamber. A stirring rod is rotatably mounted through the lower surface of the support plate A, and a stirring motor is fixedly installed on the upper surface of the support plate A. The output end of the stirring motor is fixedly connected to the upper end of the stirring rod via a coupling. A foam transfer trough is welded and installed on the front surface of the tank body. The lower surface of the inner cavity of the foam transfer trough is inclined. The rear surface of the tank has a feed inlet, and the discharge end of the foam transfer tank is connected to the external fine sorting tank. A screen plate is installed obliquely inside the transfer chamber. The screen plate is located below the overflow port, and the lower end of the screen plate is located inside the feed inlet. A support plate B is welded and fixedly installed above the transfer chamber. A double material blocking device is installed on the outside of the support plate B. The double material blocking device is located in front of the overflow port. A foam discharge device is installed inside the stirring chamber. The foam discharge device is used to push the foam in the stirring chamber into the foam transfer tank.

[0006] Preferably, the dual material blocking device includes a hydraulic telescopic rod A and a hydraulic telescopic rod B. Material blocking plates A and B are respectively fixedly installed on the lower surfaces of the hydraulic telescopic rod A and the hydraulic telescopic rod B. The lower surfaces of the material blocking plates A and B are in contact with the upper surface of the screen plate, and the left and right surfaces of the material blocking plates A and B are in contact with the inner wall of the transfer chamber.

[0007] Preferably, two U-shaped blocks are fixedly installed on the front and rear surfaces of the support plate B, respectively, and the material blocking plate A and the material blocking plate B are slidably disposed between the two U-shaped blocks that are opposite each other.

[0008] Preferably, the foam removal device includes a shaft and a servo motor. The shaft is rotatably installed inside the stirring chamber, and three connecting plates are fixedly installed on the outer surface of the shaft by bolts. Push plates are fixedly installed between the rear ends and the front ends of the three connecting plates. The servo motor is fixedly installed on the left surface of the tank, and the output end of the servo motor is fixedly connected to the left end of the shaft by a coupling.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention employs a dual structure of "initial foaming and sorting in the mixing chamber + secondary interception by the sieve plate in the transfer chamber," combined with a stirring rod and a foam removal device, to achieve graded capture of minerals in the slurry, effectively improving the mineral recovery rate. The stirring rod thoroughly mixes the slurry and reagents to form foam, and the rotating pusher plate of the foam removal device pushes the foam to the foam transfer tank. The sieve plate intercepts residual foam in the overflow slurry, preventing the loss of target minerals.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: A slurry sorting tank includes a tank body 1, a stirring chamber 11 and a transfer chamber 12 are provided inside the tank body 1, and an overflow port 13 is provided between the stirring chamber 11 and the transfer chamber 12. A support plate A2 is welded and fixedly installed above the stirring chamber 11. A stirring rod 21 is rotatably installed through the lower surface of the support plate A2, and a stirring motor 22 is fixedly installed on the upper surface of the support plate A2. The output end of the stirring motor 22 is fixedly connected to the upper end of the stirring rod 21 through a coupling. A foam transfer tank 3 is welded and installed on the front surface of the tank body 1. The lower surface of the inner cavity of the foam transfer tank 3 is inclined. A feed inlet 31 is provided on the rear surface of the foam transfer tank 3, and the discharge end of the foam transfer tank 3 is connected to an external fine sorting tank.

[0019] A screen plate 121 is fixedly installed at an inclination inside the transfer chamber 12. The screen plate 121 is located below the overflow port 13, and the lower end of the screen plate 121 is located inside the feed inlet 31. A support plate B4 is welded and fixedly installed above the transfer chamber 12. A double material blocking device 5 is installed on the outside of the support plate B4. The double material blocking device 5 is located in front of the overflow port 13.

[0020] A foam removal device 6 is installed in the mixing chamber 11. The foam removal device 6 is used to push the foam in the mixing chamber 11 into the foam transfer tank 3.

[0021] It should be noted that, in combination Figure 1 and Figure 4As shown, the dual material blocking device 5 includes a hydraulic telescopic rod A51 and a hydraulic telescopic rod B52. Material blocking plates A511 and B521 are fixedly installed on the lower surfaces of the hydraulic telescopic rods A51 and B52, respectively. The lower surfaces of the material blocking plates A511 and B521 are in contact with the upper surface of the screen plate 121, and the left and right surfaces of the material blocking plates A511 and B521 are in contact with the inner wall of the transfer cavity 12.

[0022] The extension and retraction of hydraulic telescopic rods A51 and B52 can respectively drive the material blocking plate A511 and material blocking plate B521 to move up or down, thereby realizing the blocking or releasing action of material on screen plate 121.

[0023] In addition, to ensure the stability of the movement of the material blocking plate A511 and the material blocking plate B521, two U-shaped blocks 41 that are arranged opposite each other need to be fixedly installed on the front and rear surfaces of the support plate B4 respectively. The material blocking plate A511 and the material blocking plate B521 are slidably arranged between the two U-shaped blocks 41 that are arranged opposite each other on the left and right sides, which can ensure the stability of the two material blocking plates when they are raised and lowered.

[0024] Specifically, the foam removal device 6 includes a shaft 61 and a servo motor 64. The shaft 61 is rotatably installed in the stirring chamber 11, and three connecting plates 62 are fixedly installed on the outer surface of the shaft 61 by bolts. Push plates 63 are fixedly installed between the rear end and the front end of the three connecting plates 62. The servo motor 64 is fixedly installed on the left surface of the tank 1, and the output end of the servo motor 64 is fixedly connected to the left end of the shaft 61 through a coupling.

[0025] After the servo motor 64 is started, it can drive the shaft 61 to rotate. The shaft 61 drives the push plates 63 on both sides to rotate through the connecting plate 62, thereby pushing out the foam and minerals in the stirring chamber 11 and causing them to fall into the foam transfer tank 3.

[0026] In addition, to facilitate the discharge of residual liquid in the transfer chamber 12, a slurry pump 7 needs to be fixedly installed on the right side of the tank 1. A suction pipe 71 is connected between the inlet end of the slurry pump 7 and the transfer chamber 12, and a discharge pipe 72 is connected to the discharge end of the slurry pump 7. The discharge end of the discharge pipe 72 is located in the external fine separation tank. By setting up the slurry pump 7, the slurry filtered in the transfer chamber 12 can be supplied to the external fine separation tank for reuse, thus saving resources.

[0027] Finally, since the foam has a certain stickiness, in order to ensure that the foam in the screen plate 121 and the foam transfer tank 3 can slide down smoothly, it is necessary to install water spray pipes with nozzles on the transfer chamber 12 and the foam transfer tank 3 respectively. After connecting the water spray pipes to the external high-pressure water supply equipment, water can be supplied to the transfer chamber 12 and the foam transfer tank 3 using the water flow and the inclination of the screen plate 121 and the foam transfer tank 3 to facilitate the next process in which the foam can slide down smoothly.

[0028] Working principle: During use, the slurry is injected into the mixing chamber 11, and frothers, collectors, and modifiers are added. The stirring motor 22 drives the stirring rod 21 to mix the slurry and reagents, creating foam. This causes the minerals in the slurry to float on the surface with the foam. Then, the foam removal device 6 separates the foam and minerals into the foam transfer tank 3. During the continuous injection and stirring process, the overflow slurry in the mixing chamber 11 can enter the transfer chamber 12 through the overflow port 13 and pass through the sieve plate. The foam filter in the transfer chamber 121 intercepts the foam. The intercepted foam is briefly held on the screen plate 121 by the double material blocking device 5. After the slurry enters the transfer chamber 12, the discharge position of the screen plate 121 is opened by the double material blocking device 5, and the foam is flushed down by the water pipe and enters the foam transfer tank 3 through the feed inlet 31. Finally, the foam in the foam transfer tank 3 enters the external fine sorting tank under the drive of the water flow for fine sorting again.

[0029] In summary, this device employs a dual design of "preliminary foaming and sorting in the stirring chamber 11 + secondary interception by the screen plate 121 in the transfer chamber 12" to achieve graded capture of minerals. Inside the stirring chamber 11, the reagent and slurry are thoroughly mixed by the stirring rod 21 to form foam. Minerals float to the surface with the foam and are precisely pushed to the foam transfer tank 3 by the rotating push plate 63 of the foam discharge device 6. Simultaneously, the overflow slurry from the stirring chamber 11 enters the transfer chamber 12 through the overflow port 13. The screen plate 121 effectively intercepts residual foam in the overflow slurry that has not yet been completely separated, preventing the target minerals from being lost with the residual slurry. The dual material blocking device 5 can adjust the residence time of the foam intercepted by the screen plate 121. After the slurry enters the transfer chamber 12, the foam is released, thereby improving the mineral capture rate. Compared to traditional sorting equipment, this device can effectively improve the mineral recovery rate.
