Description

Technical Field

[0001] The utility model relates to the technology of lead concentrate beneficiation, in particular to an efficient lead concentrate beneficiation device. Background Art

[0002] The beneficiation process of lead concentrate is generally produced from lead ore through processes such as crushing, ball milling, and foam flotation. Lead concentrate is the main raw material for producing metallic lead, lead alloys, lead compounds, etc.

[0003] When foam flotation is required for lead concentrate beneficiation, through the operation of a flotation machine, the ground lead ore, when being ground or after grinding, is mixed with water and necessary reagents in a stirring tank to form pulp, which is then injected into the pulp tank that has started to stir. Air is introduced into the pulp tank to form a large number of bubbles. Some mineral particles that are not easily wetted by water, that is, generally called hydrophobic mineral particles, adhere to the bubbles and float to the surface of the pulp with the bubbles to form a mineralized bubble layer. Some mineral particles that are easily wetted by water, that is, generally called hydrophilic mineral particles, do not adhere to the bubbles and remain in the pulp. The mineralized bubbles containing specific minerals are discharged, thus achieving the purpose of beneficiation.

[0004] Existing flotation devices for lead concentrate beneficiation are often not convenient for controlling the liquid level height in the pulp tank and not convenient for adjusting the height position of the material stirring component, so that when the material stirring component stirs the bubbles for discharge, it can only stir the bubbles within a fixed height range. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an efficient lead concentrate beneficiation device, which is used to solve the problems that existing flotation devices are often not convenient for controlling the liquid level height in the pulp tank and not convenient for adjusting the height position of the material stirring component.

[0006] To solve the above problems, the utility model provides an efficient lead concentrate beneficiation device, including a pulp tank. A rotatable rotating shaft is arranged inside the pulp tank. A plurality of stirring blades arranged in a circular array are fixed at the bottom of the rotating shaft. An impeller is arranged above the stirring blades. The impeller is fixedly installed with the rotating shaft. A circular plate that can move up and down is slidably connected to the rotating shaft. A floating body is fixed on the circular plate. A discharge pipe is fixedly communicated with the pulp tank. A plurality of adjusting holes are opened on the pulp tank. The adjusting holes are located below the discharge pipe. A collecting frame matched with the plurality of adjusting holes is fixed on the outer side of the pulp tank. A plurality of L-shaped rods are fixed on the circular plate. A material stirring plate is fixed at the free end of the L-shaped rod. A support block is arranged above the impeller. The support block is fixedly connected with the rotating shaft. The lower side of the circular plate can contact the upper side of the support block.

[0007] The efficient lead concentrate beneficiation device provided by the utility model also has the following technical features:

[0008] Further, a plurality of legs are fixed to the bottom of the pulp tank, and a feeding pipe is fixedly connected to the bottom of one side of the pulp tank. One end of the feeding pipe is threadedly connected with a cock.

[0009] Further, the top of the pulp tank is bolted with a bracket, and a motor is fixedly installed in the middle of the bracket. The output end of the motor is fixedly connected to the top of the rotating shaft.

[0010] Further, the material distributing plate is arranged in an inclined shape, and a plurality of through holes are formed in the stirring blades.

[0011] Further, a circular pipe is arranged outside the impeller, and support rods are fixed on the surface of the circular pipe. The free ends of the support rods are fixedly connected to the inner wall of the pulp tank.

[0012] Further, a bottom rod is fixed to the bottom of the stirring blade, a vertical block that can move up and down is slidably connected to the bottom rod, and a scraping rod is fixed to the bottom of the vertical block.

[0013] The utility model has the following beneficial effects: After the ground lead ore is mixed with water and necessary reagents in a stirring tank to form pulp, it is injected into the pulp tank. By making the liquid level at the height position of the adjustment hole, the rotation of the rotating shaft drives the stirring blades, impellers and material distributing plates to rotate. The rotation of the stirring blades can stir the pulp, while the rotation of the impellers can generate a centrifugal force to form a negative pressure, sucking in air to mix with the pulp. The material distributing plate can float on the pulp under the action of the floating body, and the rotation of the material distributing plate can facilitate the foam to be sent into the discharge pipe for discharge. When the pulp or water injected into the pulp tank is too much and the water level exceeds the height position of the adjustment hole, the pulp can be discharged through the adjustment hole into the collection frame. Then when the liquid level is lower than the height position of the adjustment hole, the pulp in the collection frame can be re-injected into the pulp tank or the pulp tank can be refilled with pulp, so as to facilitate the control of the liquid level height in the pulp tank of the pulp tank, and thus facilitate the material distributing plate to stir and discharge the foam.

[0017] The utility model will be described in detail below with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0018] Such as Figures 1 to 3In the embodiment of the high-efficiency lead concentrate beneficiation equipment of the present utility model shown, the high-efficiency lead concentrate beneficiation equipment includes a pulp tank 1. Inside the pulp tank 1, there is a rotatable rotating shaft 2. There is a pulp trough inside the pulp tank 1. At the bottom of the rotating shaft 2, a plurality of stirring blades 3 arranged in a circular array are fixed. Above the stirring blades 3, there is an impeller 4. The impeller 4 is fixedly installed with the rotating shaft 2. A circular plate 5 that can move up and down is slidably connected to the rotating shaft 2. A floating body 6 is fixed on the circular plate 5. The pulp tank 1 is fixedly communicated with a discharge pipe 7. A plurality of adjustment holes 8 are opened on the pulp tank 1. The adjustment holes 8 are located below the discharge pipe 7. A collection frame 9 that cooperates with the plurality of adjustment holes 8 is fixed on the outside of the pulp tank 1. A plurality of L-shaped rods 10 are fixed on the circular plate 5. A material shifting plate 11 is fixed at the free end of the L-shaped rod 10. Above the impeller 4, there is a support block 12. The support block 12 is fixedly connected with the rotating shaft 2. The lower side of the circular plate 5 can contact the upper side of the support block 12. After the ground lead ore is mixed with water and necessary reagents in a stirring tank to form pulp, it is injected into the pulp trough in the pulp tank 1. By making the liquid level at the height position of the adjustment hole 8, the rotating shaft 2 drives the stirring blades 3, the impeller 4 and the material shifting plate 11 to rotate. The rotation of the stirring blades 3 can stir the pulp, and the rotation of the impeller 4 can generate a centrifugal force to form a negative pressure, sucking in air to mix with the pulp. The material shifting plate 11 can float on the pulp under the action of the floating body 6, and the rotation of the material shifting plate 11 can facilitate sending the foam into the discharge pipe 7 for discharge. When the pulp or water injected into the pulp tank 1 is too much and the water level exceeds the height position of the adjustment hole 8, the pulp can be discharged through the adjustment hole 8 into the collection frame 9. Then when the liquid level is lower than the height position of the adjustment hole 8, the pulp in the collection frame 9 can be reinjected into the pulp tank 1 or the pulp tank 1 can be refilled with pulp, so as to facilitate controlling the liquid level height in the pulp trough in the pulp tank 1, so as to facilitate the material shifting plate 11 to stir and discharge the foam. And the floating body 6 can rise and fall with the liquid level height. Thus, when the liquid level is higher than the height position of the adjustment hole 8, the material shifting plate 11 can still discharge the bubbles in the foam.

[0019] In an embodiment of the present application, preferably, a plurality of legs are fixed at the bottom of the pulp tank 1. At the bottom of one side of the pulp tank 1, a blanking pipe 13 is fixedly communicated. One end of the blanking pipe 13 is threadedly connected with a plug. The blanking pipe 13 can discharge the beneficiated pulp in the pulp tank 1.

[0020] In an embodiment of the present application, preferably, the top of the pulp tank 1 is bolted with a bracket 14. A motor 15 is fixedly installed in the middle of the bracket 14. The output end of the motor 15 is fixedly connected with the top of the rotating shaft 2. By starting the motor 15, the rotating shaft 2 can be driven to rotate.

[0021] In an embodiment of the present application, preferably, the material shifting plate 11 is arranged in an inclined shape. A plurality of through holes are opened on the stirring blades 3. The inclined material shifting plate 11 can facilitate stirring the bubbles within a certain height range, and has a wider application range.

[0022] In an embodiment of the present application, preferably, a circular tube 16 is provided outside the impeller 4. A support rod 17 is fixed on the surface of the circular tube 16, and the free end of the support rod 17 is fixedly connected to the inner wall of the pulp tank 1.

[0023] In an embodiment of the present application, preferably, a bottom rod 18 is fixed to the bottom of the stirring blade 3. A vertically movable vertical block 19 is slidably connected to the bottom rod 18, and a scraping rod 20 is fixed to the bottom of the vertical block 19. The scraping rod 20 can facilitate the cleaning of the inner bottom wall of the pulp tank 1.

[0024] When the present utility model is in use, after the ground lead ore is mixed with water and necessary medicaments and adjusted into pulp in a stirring tank, it is injected into the pulp tank in the pulp tank 1. By making the liquid level at the height position of the adjustment hole 8, starting the motor 15 can drive the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 drives the stirring blade 3, the impeller 4 and the feeding plate 11 to rotate. The rotation of the stirring blade 3 can stir the pulp, and the rotation of the impeller 4 can generate a centrifugal force to form a negative pressure, sucking in air to mix with the pulp. The feeding plate 11 can float on the pulp under the action of the floating body 6, and the rotation of the feeding plate 11 can facilitate the foam to be sent into the discharge pipe 7 for discharge. When the pulp or water injected into the pulp tank 1 is too much and the water level exceeds the height position of the adjustment hole 8, the pulp can be discharged into the collection frame 9 through the adjustment hole 8. Then when the liquid level is lower than the height position of the adjustment hole 8, the pulp in the collection frame 9 can be re-injected into the pulp tank 1 or the pulp tank 1 can be refilled with pulp, so as to facilitate the control of the liquid level height in the pulp tank in the pulp tank 1, thus facilitating the feeding plate 11 to stir and discharge the foam. Moreover, the floating body 6 can rise and fall with the liquid level height. Therefore, when the liquid level is higher than the height position of the adjustment hole 8, the feeding plate 11 can still discharge the foam. Due to the inclined setting of the feeding plate 11, when the liquid level is lower than the height position of the adjustment hole 8 within a certain range, the feeding plate 11 can still discharge the foam.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
