Description

Technical Field

[0001] This utility model relates to the field of ore flotation technology, specifically to a multi-stage ore flotation mechanism. Background Technology

[0002] Flotation is a mineral processing method that uses the differences in the physical and chemical properties of mineral surfaces to float solid minerals from a suspension in water (slurry). Flotation is widely used in the mineral processing industry and is most suitable for separating disseminated ores with low grade and fine particles.

[0003] A multi-stage ore flotation mechanism, as disclosed in Chinese Patent No. CN213194151U, includes a tank. A feed inlet, a water inlet pipe, and a stirring motor are fixedly installed on the upper surface of the tank top. A main shaft is fixedly installed on the lower surface of the tank top, and stirring blades are fixedly installed on the side of the main shaft. A reaction chamber is opened inside the tank, and a discharge hopper and a blower are fixedly installed on the outer surface of the side of the tank. This invention introduces air into the mounting groove through an air pipe, causing the sealing ring to leave the surface of the mounting groove. The inclined structure of the sealing ring increases the effective contact area between air and reagents, thereby improving gas dissolution efficiency. Stopping the introduction of air into the mounting groove allows the sealing ring to adhere tightly to the mounting groove under the action of a tension spring, preventing ore from clogging the air pipe and reducing the steps required for workers to seal the air pipe, greatly enhancing its practicality.

[0004] In the process of realizing this application, the inventors discovered that the technology has at least the following problems: Although the above technical solution can increase the effective contact area between air and reagent and improve the gas dissolution efficiency, its ventilation method is from the bottom, resulting in a low air flow rate at the top, which leads to uneven dissolution of flotation reagents at different heights and affects the ore flotation effect. Therefore, further improvements can be made. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides the following technical solution: a multi-stage ore flotation mechanism, comprising a processing tank, a support leg fixedly installed at the bottom of the processing tank, a feed hopper provided at the top of the processing tank, a discharge pipe fixedly installed at the center of the bottom of the processing tank, three sets of grading screen plates provided inside the processing tank, a rotating rod rotatably connected to the center of the processing tank, a transmission component for driving the rotating rod to rotate fixedly installed at the top of the processing tank, a stirring assembly for stirring and mixing reagents provided outside the rotating rod, and an aeration assembly for increasing flotation efficiency by inflating the interior of the processing tank.

[0006] As an optimization, the stirring assembly includes an array of slide rails fixedly mounted on the outside of the rotating rod. A support rod is rotatably connected to the middle of the slide rail, and a stirring rod is fixedly mounted at the end of the support rod. A spiral blade is fixedly mounted on the outside of the stirring rod. Elastic support members are provided on both sides of the slide rail to elastically support the stirring rod. The rotation of the rotating rod will drive the stirring rod to rotate around its axis, which will cause the spiral blade to contact the raw material in the tank, thus causing the stirring rod to swing up and down. The elastic support members can assist the stirring rod in swinging up and down while rotating around the rotating rod.

[0007] As an optimization, the elastic support includes a slider that is slidably connected inside both sides of the slide rail. A support is fixedly installed on one side of the middle of the slider, and a support is fixedly installed on the upper and lower sides of the support rod. A connecting rod is hinged between the support and the support. A spring is fixedly installed between the slider and the inner wall of the slide rail.

[0008] As an optimization, guide rods are fixedly installed at the center of the inner sides of the slide rail, and the slider is slidably sleeved on the outside of the guide rods. The guide rods play a limiting and guiding role for the slider, so that the slider keeps sliding vertically.

[0009] As an optimization, the inflation assembly includes a conduit fixedly installed inside the processing tank. A hose is sealed and inserted into the top of the conduit, and the other end of the hose is connected to the air outlet of a high-pressure air pump. Several nozzles are installed on the side of the conduit opposite to the center of the processing tank. By starting the high-pressure air pump, air can be inflated along the hose into the conduit and then discharged into the tank through the nozzles.

[0010] As an optimization, an air guide groove is provided through the outer wall of the nozzle, and the end of the air guide groove near the inside of the nozzle has a frustum-shaped air inlet. The inside of the nozzle is provided with an anti-backflow component to block the air guide groove.

[0011] As an optimization, the anti-backflow component includes a fixed plate fixedly installed inside the nozzle. A slide rod is slidably inserted inside the fixed plate. A plug is fixedly installed at one end of the slide rod and is embedded in the port of the nozzle. A piston block is fixedly installed at the other end of the slide rod and is slidably connected inside the nozzle. A compression spring is fixedly installed between the piston block and the fixed plate. A rubber plug is fixedly installed on the outside of the plug at the port of the air guide groove. By inflating the nozzle, the piston block will be pushed to slide along the inner wall of the nozzle, thereby causing the plug to move out of the nozzle port.

[0012] The beneficial effects of this utility model are:

[0013] This multi-stage ore flotation mechanism uses a rotating rod to drive a stirring rod to rotate around its axis. As the spiral blades contact the raw material inside the tank, the stirring rod swings up and down, causing the slider to slide back and forth via a push-pull connecting rod. This compresses and stretches the springs on both sides, thus assisting the stirring rod in swinging and stirring. This improves the mixing effect of the reagents, ensuring full contact between the reagents and the raw material, and increasing flotation efficiency.

[0014] This multi-stage ore flotation mechanism stores elastic potential energy through a compressed spring, which then drives the piston block to slide back and reset when aeration stops. This resets the plug and embeds it in the nozzle port, causing the rubber plug to be squeezed and deformed and stuck into the air guide channel port, thus blocking the air guide channel and preventing liquid backflow in the tank, thereby minimizing liquid backflow blockage.

[0015] This multi-stage ore flotation mechanism uses a high-pressure air pump to inflate the tube into the conduit. Inflating the nozzle pushes the piston block to slide along the inner wall of the nozzle, which in turn moves the plug out of the nozzle port. This prevents the rubber plug from blocking the air guide channel port, allowing air to be inflated into the tank through the air guide channel. This ensures that the reagents and raw materials inside the tank come into full contact, further improving flotation efficiency. Attached Figure Description

[0021] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] 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.

[0023] Please see Figure 1-2 A multi-stage ore flotation mechanism includes a processing tank 1, a support leg 2 fixedly installed at the bottom of the processing tank 1, a feed hopper 3 provided at the top of the processing tank 1, a discharge pipe 4 fixedly installed at the center of the bottom of the processing tank 1, a three-group grading screen plate 5 provided inside the processing tank 1, a rotating rod 6 rotatably connected to the center of the processing tank 1, a transmission component for driving the rotating rod 6 to rotate fixedly installed at the top of the processing tank 1, a stirring assembly 7 for stirring and mixing reagents provided outside the rotating rod 6, and an aeration assembly 8 for improving flotation efficiency by aerating the interior of the processing tank 1.

[0024] Please see Figure 3 The stirring assembly 7 includes an array of slide rails 9 fixedly installed on the outside of the rotating rod 6. Guide rods are fixedly installed at the center of the inner sides of the slide rails 9, and the slider 12 is slidably sleeved on the outside of the guide rods. The guide rods limit and guide the slider 12, so that the slider 12 remains vertically sliding. A support rod is rotatably connected to the middle of the slide rail 9, and a stirring rod 10 is fixedly installed at the end of the support rod. A spiral blade 11 is fixedly installed on the outside of the stirring rod 10. Elastic support members are provided on both sides of the slide rail 9 to elastically support the stirring rod 10. The rotation of the rotating rod 6 will drive the stirring rod 10 to rotate around its axis, which will cause the spiral blade 11 to contact the raw material in the tank. Therefore, the stirring rod 10 will swing up and down. The elastic support members can assist the stirring rod 10 to swing up and down while rotating around the rotating rod 6, thereby improving the mixing effect of the reagent, making the reagent and the internal raw material fully contacted, and improving the flotation efficiency.

[0025] Please see Figure 3The elastic support includes a slider 12 that is slidably connected to the inside of both sides of the slide rail 9. A support 1 is fixedly installed on one side of the middle of the slider 12, and a support 2 is fixedly installed on the upper and lower sides of the support rod. A connecting rod 13 is hinged between the support 1 and the support 2. A spring 14 is fixedly installed between the slider 12 and the inner wall of the slide rail 9. When the stirring rod 10 swings up and down, it will push and pull the connecting rod 13, which will drive the slider 12 to slide back and forth along the inner wall of the slide rail 9. Therefore, it will compress and stretch the springs 14 on both sides respectively. Then, the spring 14 will assist the stirring rod 10 to swing and stir through its own rebound force.

[0026] Please see Figure 2 and Figure 4 The aeration assembly 8 includes a conduit 15 fixedly installed inside the processing tank 1. A hose 16 is sealed and inserted into the top of the conduit 15. The other end of the hose 16 is connected to the outlet of the high-pressure air pump. Several nozzles 17 are installed on the side of the conduit 15 opposite to the center of the inside of the processing tank 1. By starting the high-pressure air pump, air can be aerated along the hose 16 into the conduit 15 and then discharged into the tank through the nozzles 17, thereby enabling the reagent and the raw material inside to fully contact each other and improve the flotation efficiency.

[0027] Please see Figure 4 An air guide groove 18 is formed through the outer wall of the nozzle 17. One end of the air guide groove 18 near the interior of the nozzle 17 has a frustum-shaped air inlet 19. An anti-backflow component is provided inside the nozzle 17 to block the air guide groove 18. The anti-backflow component includes a fixing plate 20 fixedly installed inside the nozzle 17. A sliding rod 21 is slidably inserted into the fixing plate 20. A plug 22 is fixedly installed at one end of the sliding rod 21 and is embedded in the port of the nozzle 17. A piston block is fixedly installed at the other end of the sliding rod 21. 23, and piston block 23 is slidably connected inside nozzle 17. Compression spring 24 is fixedly installed between piston block 23 and fixed plate 20. Rubber plug 25 is fixedly installed on the outside of plug 22 corresponding to the port of air guide channel 18. By inflating the nozzle 17, piston block 23 will be pushed to slide along the inner wall of nozzle 17, which will then drive plug 22 to move out of the port of nozzle 17. Therefore, rubber plug 25 will no longer block the port of air guide channel 18, and air can be inflated into the tank through air guide channel 18.

[0028] In use, flotation reagents are first added into the tank through the hopper 3. Then, the rotating rod 6 is driven to rotate through the transmission component, which in turn drives the stirring rod 10 to rotate around its axis. This causes the spiral blades 11 to contact the raw materials in the tank, which in turn causes the stirring rod 10 to swing up and down. This pushes and pulls the connecting rod 13, which in turn causes the slider 12 to slide back and forth along the inner wall of the slide rail 9. This compresses and stretches the springs 14 on both sides, and the springs 14 themselves rebound force assists the stirring rod 10 in swinging and stirring.

[0029] At the same time, the high-pressure air pump will inflate the tube 15 through the hose 16. Inflate the nozzle 17, which will push the piston block 23 to slide along the inner wall of the nozzle 17. This will cause the plug 22 to move out of the nozzle 17 port, so that the rubber plug 25 will no longer block the air guide channel 18 port. At this time, air can be inflated into the can through the air guide channel 18, so that the medicine and the internal raw materials can be fully contacted.

[0030] When the nozzle 17 is no longer filled with air, the compressed spring 24 will cause the piston block 23 to slide back and reset, which will cause the plug 22 to reset and be embedded in the port of the nozzle 17. This will cause the rubber plug 25 to be squeezed and deformed and stuck into the port of the air guide channel 18, thus blocking the air guide channel 18 and preventing the liquid in the tank from flowing back.

[0031] In summary, this multi-stage ore flotation mechanism, by rotating the rotating rod 6, drives the stirring rod 10 to rotate around its axis. As the spiral blades 11 contact the raw material inside the tank, they cause the stirring rod 10 to swing up and down. This causes the slider 12 to slide back and forth via the push-pull connecting rod 13, which in turn compresses and stretches the springs 14 on both sides. This assists the stirring rod 10 in swinging and stirring, thereby improving the mixing effect of the reagents and ensuring that the reagents and the raw material inside are in full contact, thus improving the flotation efficiency.

[0032] By accumulating elastic potential energy through the compressed spring 24, the piston block 23 can be driven to slide back and reset when inflation stops. This will cause the plug 22 to reset and be embedded in the port of the nozzle 17. Consequently, the rubber plug 25 will be squeezed and deformed and stuck into the port of the air guide 18, thus blocking the air guide 18 to prevent the liquid in the tank from flowing back, thereby minimizing the risk of liquid backflow and blockage.

[0033] The high-pressure air pump inflates the tube 15 through the hose 16. Inflating the nozzle 17 pushes the piston block 23 to slide along the inner wall of the nozzle 17, which in turn moves the plug 22 out of the nozzle 17 port. This prevents the rubber plug 25 from blocking the air guide channel 18 port. At this point, air can be inflated into the tank through the air guide channel 18, which allows the reagent and the raw material inside to come into full contact, thereby further improving the flotation efficiency.
