Description
Technical Field
[0001] This invention relates to the field of mineral processing technology, specifically to a high-performance and low-cost mineral processing device. Background Technology
[0002] A mineral separator is a device used for the physical separation and purification of ore raw materials. It mainly separates useful minerals from gangue or impurities by differences in density, particle size, or magnetic and electrical physical properties. This equipment is commonly used in the fields of metal mining, non-metal mining, and tailings reprocessing, and can realize the classification and recovery of minerals.
[0003] For existing mineral processing equipment, flotation is used for separation. Although flotation has a high separation efficiency, it relies on chemical reagents, which can easily lead to serious environmental pollution and high mineral processing costs. Gravity separation, on the other hand, is less polluting, but generally involves large equipment investment and limited separation efficiency. In addition, for low-grade or mixed ores, flotation has low separation efficiency and it is difficult to achieve efficient and clean resource recovery. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the present invention provides a high-performance and low-cost mineral processing device, which solves the problems that although flotation has high separation efficiency, it relies on chemical reagents, which can easily lead to serious environmental pollution and high mineral processing costs.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-performance and low-cost mineral processing device, comprising a hydraulic mixing tank 1, a mineral powder feed hopper fixedly connected inside the hydraulic mixing tank 1, a water inlet pipe 1 inside the mineral powder feed hopper, a water inlet pipe 2 inside the hydraulic mixing tank 1, a coarse mineral powder outlet mechanism at the lower opening of the hydraulic mixing tank 1, a hydraulic mixing tank 2 fixedly connected to the right outer wall of the hydraulic mixing tank 1, a water inlet pipe 3 inside the hydraulic mixing tank 2, an outlet trough 1 and an outlet trough 2 inside the hydraulic mixing tank 2, a water level balancer 1 and a water level balancer 2 fixedly connected to the outer wall of the hydraulic mixing tank 2, both the water level balancer 1 and the water level balancer 2 being equipped with a buoyancy filter mechanism, and a communication mechanism inside both the hydraulic mixing tank 1 and the hydraulic mixing tank 2.
[0006] The above scheme involves a mineral powder feed hopper consisting of a conical hopper and a rectangular channel. The rectangular channel has an inlet pipe to provide water flow for the mineral powder entering the hydraulic mixing tank. The conical hopper allows the material to enter the hydraulic mixing tank under gravity. Both hydraulic mixing tanks 1 and 2 have openings on their contact sides, connected by a connecting mechanism. This allows the mineral powder in the hydraulic mixing tank 1 to mix with water, float in the water, and enter the hydraulic mixing tank 2. After passing through the outlet trough, the material is filtered and separated by a buoyancy filtration mechanism.
[0007] Preferably, the connecting mechanism includes a connecting plate, the outer wall of which is fixedly connected to the interior of hydraulic mixing tank one and hydraulic mixing tank two, and the interior of the connecting plate has a connecting port corresponding to the water outlet tank one.
[0008] Preferably, the buoyancy filtration mechanism includes a buoyancy filter screen and a buoyancy filter screen base plate, the buoyancy filter screen and the buoyancy filter screen base plate are connected, and the outer wall of the buoyancy filter screen base plate is fixedly connected to the inside of the water level balancer.
[0009] Preferably, the hydraulic distribution box two has an inlet trough inside, and the inlet trough is located on the upper side of the hydraulic distribution box two.
[0010] Preferably, both the first and second water level balancers are provided with tailings outlets inside, and the tailings outlets are located on the right side of the first and second water level balancers.
[0011] Preferably, the bottom plate of the buoyancy filter has a groove inside, which guides the tailings outlet.
[0012] Preferably, the first water outlet tank and the first water level balancer are located on the upper side of the second hydraulic distribution box, and the second water outlet tank and the second water level balancer are located on the lower side of the second hydraulic distribution box.
[0013] Preferably, the coarse ore powder outlet mechanism includes a conical frame, the outer wall of which is fixedly connected to the lower opening of the hydraulic mixing tank, a control valve is provided inside the conical frame, and an ore powder outlet is provided inside the conical frame.
[0014] Preferably, each of the first water level balancers has a fine product outlet fixedly connected inside, and the second water level balancer has a medium product outlet fixedly connected inside.
[0015] Preferably, the water level balancer has an inlet hole inside, which corresponds to the fine product outlet and the medium product outlet respectively, and an inner mesh gasket is provided inside the water level balancer.
[0016] Working principle: External clean water is introduced through the inlet pipe to fill the hydraulic mixing tank with appropriate moisture. Mineral powder enters the hydraulic mixing tank through the mineral powder feed hopper and is sorted under the action of gravity. The remaining mineral powder passes through the connecting mechanism and enters the hydraulic mixing tank from the hydraulic mixing tank to the hydraulic mixing tank. The remaining mineral powder is filtered and sorted by the buoyancy filter mechanism through the water level balancer and the water level balancer.
[0017] This invention provides a high-performance and low-cost mineral processing device. It has the following advantages:
[0018] 1. This invention uses a hydraulic mixing tank to perform hydraulic gravimetric separation. The separated mineral powder is discharged through a coarse ore powder outlet mechanism, and then undergoes secondary hydraulic gravimetric separation through a hydraulic mixing tank, separating the mineral powder into three categories: coarse, medium, and fine mineral powder. The coarse ore powder is discharged from the discharge hole at the bottom of the hydraulic mixing tank, the medium ore powder is discharged from the water outlet trough at the bottom of the hydraulic mixing tank, and the fine ore powder enters the water level balancer at the top of the hydraulic mixing tank for filtration and separation. This avoids the use of chemical agents and achieves a pollution-free mineral processing effect. Through a simple structure, it achieves low mineral processing costs and solves the problem of low-grade ore having no mining value.
[0019] 2. This invention filters and sorts mineral powder through a buoyancy filter mechanism using water level balancer one and water level balancer two. Mineral powder that has not been filtered and sorted by the buoyancy filter mechanism flows to the tailings outlet, thus avoiding affecting the use of water level balancer one and water level balancer two. At the same time, it realizes multi-stage filtration and sorting, effectively separating coarse and fine particles, and avoiding the low efficiency of traditional single-stage sorting.
[0020] 3. The present invention, through the setting of the second water inlet pipe, not only provides water flow to the interior of the hydraulic mixing tank, allowing the water flow inside the hydraulic mixing tank to facilitate the guidance of mineral powder that has not passed the hydraulic weight separation, so that the mineral powder can enter the interior of the hydraulic mixing tank for filtration and separation; through the setting of the third water inlet pipe, not only provides water flow to the interior of the hydraulic mixing tank, but also facilitates the flow of water at the bottom of the hydraulic mixing tank, preventing the accumulation of mineral powder at the bottom of the hydraulic mixing tank.

[0041] Please see the appendix Figure 3 The bottom plate 1402 of the buoyancy filter has a groove inside, which guides the tailings outlet 15.
[0042] Specifically, the grooves in the bottom plate 1402 of the buoyancy filter facilitate the flow of mineral powder that has not been filtered by the filter components through the grooves to the tailings outlet 15 for discharge.

[0044] Specifically, the water level balancer 8 and its connecting structure are located on the upper side of the hydraulic mixing box 6, while the water level balancer 11 and its connecting structure are located on the lower side of the hydraulic mixing box 6, which facilitates the separation of mineral powder on the upper and lower sides of the hydraulic mixing box 6.
[0045] Please see the appendix Figure 5 - Appendix Figure 8 The coarse ore powder outlet mechanism 5 includes a conical frame 501.

[0051] Workflow: When using this mineral concentrator, the material enters the hydraulic mixing tank 1 through the mineral powder feed hopper 2. Clean water is introduced from the outside through the water inlet pipe 3 to provide power for the mineral powder separation process. After the mineral powder mixes with the water inside the hydraulic mixing tank 1, the gravity of the coarse mineral powder is greater than its buoyancy, causing this part of the mineral powder to accumulate on the lower side of the hydraulic mixing tank 1. A conical frame 501 is connected to the lower opening of the hydraulic mixing tank 1. The timed start and stop of the control valve 502 facilitates the timed discharge of the coarse mineral powder accumulated at the conical frame 501 from the ore powder outlet 503, realizing the separation of coarse mineral powder. The remaining mineral powder mixes with water and is introduced from the outside through the water inlet pipe 2. The floating mineral powder inside the hydraulic mixing tank 1 flows into the hydraulic mixing tank 2 6 under the guidance of the connecting mechanism 13.
[0052] The remaining mineral powder is sorted inside the hydraulic mixing tank 26. The medium mineral powder is discharged from the water outlet 210 at the bottom of the hydraulic mixing tank 26. After passing through the water level balancer 211 and the buoyancy filter mechanism 14 on the lower side, the discharged medium mineral powder is sorted. The fine mineral powder is discharged to the water level balancer 8 through the water outlet 17 on the upper side of the hydraulic mixing tank 26. With the cooperation of the water level balancer 18 and the buoyancy filter mechanism 14, the fine mineral powder is filtered and sorted. The mineral powder that passes through the water level balancer 18 and the water level balancer 211 without passing through the filter is discharged through the tailings outlet 15. Finally, the coarse, medium and fine mineral powders are separated through the ore powder outlet 503, the medium product outlet 17 and the fine product outlet 16, thereby realizing the automatic filtration and sorting of mineral powder.
