Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of thickener, in particular to a thickener with defoaming function. BACKGROUND

[0002] The formation of gold deposits is usually related to fault zones, and is often found in ultramylonite, mylonite, micro-sand sugar-like quartzite and talc-schist, which are often the location of gold-rich ore bodies. Among them, talc-schist is a relatively common type of gold deposit, and the talc contained therein has a relatively obvious grinding aid effect, especially for natural gold ore, when the overall grinding fineness of the ore is 70% to 80% of-200 mesh, part of the natural gold can be ground to more than 70% of-400 mesh, and then the gold concentrate obtained by flotation can be concentrated and precipitated by a thickener.

[0003] However, the existing thickener has the following disadvantages:

[0004] For this type of gold ore containing talc, as talc acts as a grinding aid, the grinding effect of natural gold can be significantly improved, although it helps to dissociate gold monomers, but when the thickener is concentrated and precipitated, a large amount of gold concentrate cannot be precipitated in time due to its light weight under the adsorption of flotation reagents, resulting in its adsorption on the foam, and the foam floats on the surface layer of the thickener liquid surface, not only causing the part of gold to be precipitated to the bottom of the thickener to be collected, but also slowly flowing out with overflow, causing loss of gold resources. If the foam is simply broken up, the flow in the thickener will increase and be unstable, which will affect the settling of gold. Currently, a water spraying method is used for the foam, but the effect is not good.

[0005] Therefore, we propose a thickener with defoaming function to solve the problems mentioned above. SUMMARY

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention involves sending upward-moving foam through the gap between two baffles and the defoaming tank to the surface of a sliding plate. The contact between the sliding plate and the foam, along with friction, causes some of the foam to break. Two water pumps are then activated, drawing defoaming agent into two collection tanks via connecting pipes. The defoaming agent enters the baffles through the delivery pipe, treating any remaining small amount of foam. The resulting liquid then enters the thickening tank through a connecting pipe, effectively treating the foam in the solution within the thickening tank and solving the problem of excessive foam affecting gold precipitation in existing thickeners.

[0019] 2. When the equipment of the present invention needs to precipitate gold in metal ore, the metal ore is first transported to the inside of the filter tank. The material moves downward through the first and second slides. Under the action of friction, some of the foam is broken, and the remaining foam remains on the surface of the two slides. Finally, the liquid flows out from the gap between the second slide and the inside of the filter tank, preventing the material entering the thickening tank from containing foam.

[0020] 3. In order to quickly break up a portion of the foam, the device of the present invention starts the forward and reverse motors, which drive the pressure plate to move back and forth on the outer surface of the threaded rod. The foam will be squeezed and broken, turning into liquid that flows out from the inside of the filter tank. Through the action of the filter components, a portion of the foam in the metal ore solution is effectively treated. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 As shown, the present invention provides a technical solution: a thickener with defoaming function, comprising: two fixed rods 1, a thickening tank 2 installed between the outer surfaces of the two fixed rods 1, a defoaming component 5, the defoaming component 5 including a defoaming tank 501, baffles 502 fixedly installed on the opposite inner walls of the defoaming tank 501, sliding plates 503 fixedly connected to the outer surfaces of the two baffles 502, a collection tank 504 provided at the top of the defoaming tank 501 near the two side edges, a water pump 505 provided at the top of the defoaming tank 501 near the two side edges, a connecting pipe 506 fixedly connected to the inlet end of the two water pumps 505, a conveying pipe 507 fixedly connected to the outlet end of the two water pumps 505, and two connecting pipes 509 fixedly connected inside the defoaming tank 501, with perforated plates 508 fixedly installed on the inner walls of the two connecting pipes 509.

[0032] At the same time, according to Figures 1-4 and Figures 7-8As shown, one end of each of the two connecting pipes 506 is fixedly inserted into the interior of the two collection tanks 504, the bottom ends of the two conveying pipes 507 are fixedly inserted into the interior of the defoaming tank 501, and one end of each of the two connecting pipes 509 is inserted into the interior of the thickening tank 2. Defoamer is drawn into the interior of the two collection tanks 504 through the connecting pipes 506, and the defoamer enters the interior of the baffle 502 from the interior of the conveying pipes 507. Then the generated liquid enters the interior of the thickening tank 2 through the connecting pipes 509.

[0033] according to Figures 1-4 and Figure 6 As shown, a filter assembly 4 is provided at the bottom of the defoaming component 5. The filter assembly 4 includes a filter tank 401. The bottom of the defoaming tank 501 is fixedly connected to the top of the filter tank 401. A support plate 3 is fixedly connected to the bottom of the filter tank 401. The outer surface of the support plate 3 is fixedly connected to the outer surface of the thickening tank 2. A first slope 402 is fixedly connected between the opposite inner walls of the filter tank 401. A perforated plate 403 is fixedly connected to the outer surface of the first slope 402. The opposite outer surfaces of the perforated plate 403 are fixedly connected to the opposite inner walls of the filter tank 401. Metal ore enters the filter tank 401. Inside 01, the material first passes through the first slipway 402. Under the action of gravity, the flow of liquid is greater than that of foam, which retains the foam on the surface of the first slipway 402. Through the action of the support plate 3, the filter tank 401 is made more stable. The defoaming tank 501 and the filter tank 401 are connected to facilitate the entry of foam from the filter tank 401 into the defoaming tank 501. Some of the liquid can directly enter the bottom of the filter tank 401 through the small holes on the surface of the perforated plate 403 and enter the interior of the thickening tank 2 along the discharge pipe 410.

[0034] according to Figure 7 As shown, a second slope 404 is fixedly installed on the outer surface of the filter plate 403. The opposite outer surfaces of the second slope 404 are fixedly connected to the opposite inner walls of the filter tank 401. Limiting blocks 405 are fixedly installed on the opposite outer surfaces of the filter tank 401. A forward and reverse motor 406 is provided on the outer surface of one of the limiting blocks 405. A portion of the liquid continues to move downward along the second slope 404. During the movement, a portion of the foam will be retained on the surface of the second slope 404. Finally, the liquid flows downward from the gap between the second slope 404 and the interior of the filter tank 401. The installation of the forward and reverse motor 406 is facilitated by the function of the limiting block 405.

[0035] according to Figure 6As shown, the output shaft of the forward and reverse motor 406 is fixedly connected to a threaded rod 407. A pressure plate 408 is threadedly fitted onto the outer surface of the threaded rod 407. One end of the threaded rod 407 extends movably through the outside of the limiting block 405. A limiting post 409 is movably embedded inside the pressure plate 408. When the forward and reverse motor 406 is started, the threaded rod 407 is driven to rotate. At the same time, under the limiting action of the limiting post 409, the pressure plate 408 moves back and forth on the outer surface of the threaded rod 407. By extending one end of the threaded rod 407 movably through the outside of the limiting block 405, the threaded rod 407 becomes more stable during rotation.

[0036] according to Figures 1-2 and Figure 6 As shown, the two ends of the limiting post 409 are fixedly connected to the outer surfaces of the two limiting blocks 405 respectively. The filter tank 401 is fixedly connected to the discharge pipe 410 near the bottom. One end of the discharge pipe 410 is fixedly inserted into the interior of the thickening tank 2. The position of the limiting post 409 is fixed by the fixing between the limiting post 409 and the two limiting blocks 405. A portion of the liquid directly enters the bottom surface of the filter tank 401 through the small holes on the surface of the baffle plate 403, and then enters the interior of the thickening tank 2 along the discharge pipe 410.

[0037] according to Figures 1-5 As shown, a fixed frame 6 is fixedly connected to the top of the thickening tank 2, and a support frame 7 is fixedly installed on the top of the fixed frame 6. A transmission device 8 is provided on the inner top surface of the support frame 7, and a rotating rod 9 is provided on the output shaft of the transmission device 8. The bottom end of the rotating rod 9 extends movably through to the outside of the fixed frame 6. Through the action of the fixed frame 6 and the support frame 7, the transmission device 8 is limited, and the rotating rod 9 is driven to rotate by the transmission device 8. By extending the rotating rod 9 through to the outside of the fixed frame 6, the connection between the rotating rod 9 and the target frame 11 is facilitated.

[0038] according to Figures 1-6 As shown, a feeding bucket 10 is fixedly connected to the bottom of the fixed frame 6, and one end of the discharge pipe 410 is fixedly inserted into the inside of the feeding bucket 10. Five target frames 11 are fixedly connected to the outer surface of the rotating rod 9. Before the material enters the inside of the thickening tank 2 through the discharge pipe 410, it first enters the inside of the feeding bucket 10. Through the function of the feeding bucket 10, the discharge pipe 10 is prevented from directly contacting the top of the thickening tank 2, and foam is prevented from being generated by the slurry under the action of gravity. The rotating rod 9 and the target frames 11 rotate to scrape the particles that are stuck on the inner wall of the thickening tank 2 to the center position of the thickening tank 2.

[0039] according to Figures 1-5As shown, four limiting rods 12 are fixedly connected to the inner wall of the thickening tank 2. A limiting ring 13 is fixedly connected between one end of the four limiting rods 12. The bottom end of the rotating rod 9 extends into the interior of the rotating rod 9. In order to maintain the stability of the rotating rod 9, the limiting rod 9 is limited by the limiting rods 12 and the limiting ring 13, so that it is more stable during rotation.

[0040] according to Figures 1-4 As shown, an inner overflow weir 14 is provided at the top of the thickening tank 2, and a connecting hole 15 is provided on the inner wall of the inner overflow weir 14. A water outlet pipe 16 is fixedly connected inside the inner overflow weir 14. Finally, the clear water at the top of the thickening tank 2 enters the interior of the inner overflow weir 14 through the connecting hole 15 and flows out along the water outlet pipe 16.

[0041] The overall effect of the mechanism is as follows: when it is necessary to precipitate gold in metal ore, the external conveying mechanism is first connected to... Figure 2 The feed chute connected to the surface of the filter tank 401 allows the metal ore to enter the interior of the filter tank 401. The material first passes through the first slipway 402. Under the action of gravity, the flow of liquid is greater than that of foam, causing the foam to be retained on the surface of the first slipway 402. Part of the liquid directly enters the bottom of the filter tank 401 through the small holes on the surface of the perforated plate 403, and then enters the interior of the thickening tank 2 along the discharge pipe 410. The small holes on the surface of the perforated plate 403 can retain larger foam on the outer surface of the perforated plate 403, while smaller foam will also be squeezed out by the action of the perforated plate 403 and flow downward. Another part of the liquid continues to move downward along the second slipway 404. During the movement, some foam will be retained on the surface of the second slipway 404. Finally, all the liquid flows out from between the second slipway 404 and the interior of the filter tank 401. The foam flows downward through the gaps. Because the gap between the second landslide 404 and the filter tank 401 is small, some foam is crushed when it passes through this gap. The unbroken foam remains on the surface of the second landslide 404. Then, the forward and reverse motors 406 are activated, driving the threaded rod 407 to rotate. Simultaneously, under the limiting action of the limiting post 409, the pressure plate 408 moves back and forth on the outer surface of the threaded rod 407. When the pressure plate 408 contacts the inner wall of the filter tank 401, the foam is crushed and becomes liquid, flowing out from the inside of the filter tank 401. Through the action of the filter assembly 4, some of the foam in the metal ore solution is effectively treated, preventing foam from entering the thickening tank 2. Because a large amount of foam remains inside the filter tank 401, another portion of the foam is squeezed upwards during the compression process, flowing out from... Figure 8The foam flows through the gaps between the two baffles 502 and the defoaming tank 501 to the surface of the slide plate 503. Through the contact between the slide plate 503 and the foam, and under the action of friction, some of the foam breaks down, turning into liquid that enters the interior of the defoaming tank 501. Then, two water pumps 505 are activated, drawing defoaming agent into the two collection tanks 504 through connecting pipes 506. The defoaming agent enters the interior of the baffles 502 through the delivery pipe 507. The defoaming agent is composed of surfactants, polysiloxanes, mineral oil, citrate, and dodecyl alcohol. The remaining small amount of foam in the baffles 502 is treated by the defoaming agent. The resulting liquid then enters the thickening tank 2 through the connecting pipe 509. Figure 8 As shown, the two perforated plates 508 prevent unbroken foam from entering the connecting pipe 509. The defoaming component 5 effectively treats the foam in the solution entering the thickening tank 2, solving the problem of excessive foam affecting gold precipitation in existing thickeners. When the material enters the thickening tank 2, the solid particles and liquid interact, colliding and rubbing against each other. During this process, a network structure forms between the solid particles. This structure can aggregate smaller solid particles into larger blocks, and the larger blocks... The lumps sink to the bottom of the thickening tank 2 under their own gravity. Then, the transmission device 8 drives the rotating rod 9 to rotate. The rotating rod 9 and the target frame 11 rotate, scraping the particles stuck on the inner wall of the thickening tank 2 to the center of the thickening tank 2. Finally, they flow out through the discharge port at the bottom of the thickening tank 2. During the rotation of the rotating rod 9, in order to maintain the stability of the rotating rod 9, the limiting rod 9 is limited by the limiting rod 12 and the limiting ring 13 to make it more stable during the rotation. Finally, the clear water at the top of the thickening tank 2 enters the interior of the inner overflow weir 14 through the connecting hole 15 and finally flows out through the water outlet pipe 16, thus completing the precipitation of the metal.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
