Description

Technical Field

[0001] This utility model relates to the field of ore sorting technology, specifically a dewatering tank for mineral processing. Background Technology

[0002] Magnetic dewatering tanks, also known as magnetic washing tanks, are separation devices that combine magnetic force and gravity. They are widely used in magnetic separation processes to remove ores and fine gangue, and can also be used as thickening equipment for filtration. Currently, magnetic dewatering tanks are classified into two types based on their magnetic source: magnetic dewatering tanks and electromagnetic dewatering tanks. Existing cyclone magnetic dewatering tanks are prone to clogging of the discharge pipes during slurry discharge, affecting the equipment's performance. Even if the discharge pipe is opened promptly, the slurry easily clogs it, resulting in poor practicality. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] See Figures 1-3In this embodiment of the present invention, a dewatering tank for mineral processing includes a base 1, a discharge cone 3, a rotating shaft 8, a tower-shaped magnetic system 10, a nozzle 13, and a feeding assembly. A support frame 2 is fixedly connected to the base 1, and the discharge cone 3 is fixedly connected to the support frame 2. A dewatering tank 4 is fixedly connected to the top of the discharge cone 3. Multiple sets of equidistantly distributed second collection tanks 14 are arranged on the inner wall of the dewatering tank 4. The present invention uses the second collection tanks 14 to prevent magnetic mineral particles from being rotated out by centrifugal force. The nozzle 13 is installed at the bottom of the dewatering tank 4 with its nozzle facing upwards. An overflow port 15 is provided at the top of the dewatering tank 4. The rotating shaft 8 is located inside the discharge cone 3, and a conical spiral groove 9 is fixedly connected to the rotating shaft 8. The tower-shaped magnetic system 10 is installed at the top of the conical spiral groove 9. A discharge port 6 is provided at the bottom of the discharge cone 3. The feeding assembly is installed inside the dewatering tank 4 and is used to feed the dewatering particles into the tank. The dewatering tank 4 is continuously fed with raw materials. Firstly, the raw ore is received by the feeding assembly and continuously discharged into the dewatering tank 4. Simultaneously, water is continuously pumped upwards into the dewatering tank 4 through the nozzle 13. At this time, magnetic mineral particles, under the action of magnetic force and gravity, overcome the upward force of the rising water flow and settle to the bottom of the dewatering tank 4. Non-magnetic fine gangue and sludge, under the action of the rising water flow, overcome gravity and other forces and flow into the overflow port 15. Meanwhile, the rotating shaft 8 drives the conical spiral groove 9 and the tower-shaped magnetic system 10 to rotate. The tower-shaped magnetic system 10 then rotates the water in the dewatering tank 4, thereby accelerating the discharge of non-magnetic fine gangue and sludge by the rising water flow. At the same time, magnetic mineral particles attached to the surface of the tower-shaped magnetic system 10 move into the conical spiral groove 9 under the action of centrifugal force, and finally move along the conical spiral groove 9 into the discharge cone 3, and then are discharged through the discharge port 6, thus completing the mineral processing.

[0020] In one instance of this embodiment, please refer to Figures 1-3 The overflow port 15 is provided with a third collection tank 24 fixedly connected to the outer wall of the dewatering tank 4. The third collection tank 24 is provided with a second discharge port 25. The present invention collects the wastewater and slag discharged from the overflow port 15 through the third collection tank 24 and discharges them along the second discharge port 25.

[0021] In one instance of this embodiment, please refer to Figures 1-3 The outer wall of the discharge port 6 is provided with a first collection trough 5 fixedly connected to the bottom of the discharge cone 3. The first collection trough 5 is provided with a first discharge port 23. The present invention collects the raw ore discharged from the discharge port 6 through the first collection trough 5 and discharges it along the first discharge port 23.

[0022] In one instance of this embodiment, please refer to Figures 1-3The bottom of the first collection tank 5 is fixedly connected to a motor 7, and the output shaft of the motor 7 is fixedly connected to a rotating shaft 8. The present invention drives the rotating shaft 8 to rotate through the motor 7.

[0023] In one instance of this embodiment, please refer to Figures 1-3 A main pipe 11 is provided on the outer wall of the dehydration tank 4. The main pipe 11 is connected to the nozzle 13. A connector 12 is connected to the main pipe 11. The present invention connects the water supply equipment through the connector 12 and supplies water to multiple sets of nozzles 13 synchronously through the main pipe 11.

[0024] In one instance of this embodiment, please refer to Figures 1-3 The feeding assembly includes a feeding hopper 16 fixedly connected to the dewatering tank 4. A fixing frame 17 is fixedly connected inside the feeding hopper 16, and a threaded cylinder 18 is fixedly connected to the fixing frame 17. A screw 19 is threadedly connected inside the threaded cylinder 18. A discharge pipe 21 is fixedly connected to the bottom of the feeding hopper 16, and a control valve 22 is slidably connected inside the discharge pipe 21. The control valve 22 is fixedly connected to the screw 19, and a crank handle 20 is fixedly connected to the upper part of the screw 19. The feeding assembly can first pass through the feeding hopper 16. 6. The raw materials are placed in a container and discharged into the dewatering tank 4 through the discharge pipe 21. The screw 19 can be rotated by shaking the handle 20. The screw 19 is connected to the threaded cylinder 18 by a thread, which converts the rotational motion of the screw 19 into the linear motion of the screw 19, thereby driving the screw 19 to rotate and lift. The screw 19 drives the control valve 22 to slide and lift in the discharge pipe 21, thereby adjusting the size of the opening of the discharge pipe 21, and finally realizing the adjustment of the feeding speed.
