Description

Technical Field

[0001] This invention belongs to the field of metal recycling technology, specifically a method and apparatus for low-temperature smelting of antimony resources. Background Technology

[0002] Antimony is a silvery-white, lustrous, hard, and brittle metal (often made into rods, blocks, powder, and other shapes), with a scaly crystal structure. It gradually loses its luster in moist air and burns into white antimony oxide when heated. It is readily soluble in aqua regia and concentrated sulfuric acid. Its relative density is 6.68, melting point is 630°C, boiling point is 1635°C, atomic radius is 1.28 Å, and electronegativity is 2.2.

[0003] A patent with publication number CN106756110A discloses a safe, environmentally friendly, reliable, low-investment, and low-operating-cost method for purifying antimony materials based on arsenic sublimation, suitable for industrial production. It includes the following steps: First, the antimony raw material to be processed is fed into a heating furnace by a feeding device; second, an arsenic and its compound vapor collection device is fixed above the furnace body; third, at least one mesh is placed on top of the arsenic vapor collection device; fourth, the temperature of the heater is set in the temperature range where arsenic sublimates but antimony does not, to continuously heat the antimony raw material; fifth, heating is stopped and the purified antimony raw material is removed after the volume of the collected material on the collection device no longer increases significantly; sixth, new antimony raw material is added, and the purification operation continues.

[0004] In current technologies, before secondary smelting and purification, the existing antimony resources are pulverized to facilitate faster separation of impurities. The raw materials are then mixed with a raw material, flux, and desulfurizing agent on the surface of the dried and pulverized material. However, this mixture of antimony materials causes them to stick together and form small pieces, increasing their volume. This results in blockages on the sieve openings during screening and equalization.

[0005] Therefore, the present invention provides a method and apparatus for low-temperature smelting of antimony resources. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] Firstly, the technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a low-temperature smelting device for antimony resources, comprising a support frame 1 and a low-temperature smelting and purification tank detachably installed on the outer surface of the support frame 1, a limiting slider movably overlapping the top outer surface of the support frame 1, a limiting track bar movably sleeved on the inner wall of the limiting slider on the top surface of the support frame 1, two sets of hydraulic rods 1 fixedly installed on the back of the support frame 1, two sets of motors 2 fixedly installed on the top surface of the limiting slider and at the two side edges, two sets of transmission tracks movably sleeved on the outer surface of the output ends of the two sets of motors 2, a support frame 4 provided on the top surface of the limiting slider and at the other two side edges, a rotating rod movably sleeved on the outer surface of the support frame 4, a disintegration discharge cylinder fixedly installed on one side surface of the support frame 4, a screen plate provided on the inner wall of the disintegration discharge cylinder, and a triangular extrusion arm plate movably overlapping the bottom surface of the screen plate fixedly connected to the bottom end of the rotating rod; A material discharge groove is provided on the surface of the screen plate, a swing plate is fixedly connected to the bottom surface of the screen plate, and a conical push block is fixedly installed on the top surface of the swing plate and movably sleeved on the inner wall of the material discharge groove.

[0008] Preferably, two sets of hydraulic rods are fixedly installed on the top surface of the limiting slider and at the two side edges, and two sets of limiting support rods are fixedly installed on the top surface of the limiting slider and at the two side edges of the hydraulic rods.

[0009] Preferably, a lifting push plate is fixedly connected to the output end of the hydraulic rod two and is movably sleeved on the outer surface of the limiting support rod, and the bottom surface of the support frame four is fixedly connected to the top surface of the lifting push plate.

[0010] Preferably, a support frame three is fixedly connected to the top surface of the lifting push plate and at the two side edges, the bottom surface of the motor two is fixedly installed on the top surface of the support frame three, and a push plate is fixedly installed on the top outer surface of the limiting slider.

[0011] Preferably, a second support frame is fixedly installed on the top surface of the first support frame and disposed on the outer surface of the first hydraulic rod, and four sets of motors are symmetrically fixedly installed on the two side surfaces of the first support frame.

[0012] Preferably, a limiting lap rod is movably sleeved on the outer surface of the support frame one, and a transmission toothed cylinder is provided on the outer surface of the limiting lap rod.

[0013] Preferably, the output end of the motor is threadedly and movably sleeved on the outer surface of the transmission toothed cylinder, and a limiting collar is fixedly installed on the other end of the limiting lap rod on the outer surface of the low-temperature smelting and purification tank.

[0014] Preferably, an impurity collection trough is movably connected to the bottom surface of the support frame one and located at the bottom edge of the output end of the low-temperature smelting and purification tank, and the output end of the hydraulic rod one is fixedly connected to the surface of the push plate.

[0015] Preferably, the outer surface of the bottom end of the rotating rod is movably sleeved at the center position of the screen plate, and the outer surfaces of the two sets of transmission tracks are movably adjusted to the top edge position of the rotating rod.

[0016] Secondly, a low-temperature smelting method for antimony resources includes the following steps: S1. The antimony raw material after one purification is crushed, and the crushed antimony raw material is dried and preliminarily removed. S2. Add mixing agent, flux and desulfurizing agent to the inside of the antimony particles after the first impurity removal, and guide the antimony particles into the inside of the conveying tank; S3. At this time, the delivery device moves the conveying tank to the top edge of the low temperature smelting and purification tank, and the triangular extrusion arm plate shakes the antimony raw material inside the low temperature smelting and purification tank evenly down in sequence. S4. When the antimony raw material is heated at high temperature, the mixed raw materials, flux and desulfurizing agent adhering to the surface of the antimony raw material will cause the residue inside the antimony raw material to be discharged, and the low temperature smelting and purification tank will carry out secondary heating and purification treatment of the antimony raw material. S4. After the antimony raw material is purified for the second time, the slag floating on the top layer is collected and the remaining antimony raw material is recycled.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses a method and apparatus for low-temperature smelting of antimony resources. Antimony raw materials mixed with raw materials, flux, and desulfurizing agents are placed inside a differentiation and feeding cylinder, causing the antimony raw materials to accumulate on the surface of a screen plate. A hydraulic rod then pushes a pair of limiting sliders, causing the limiting sliders to slide on the surface of a limiting track, moving the differentiation and feeding cylinder to the top edge of the low-temperature smelting and purification tank. A motor then drives a transmission belt, causing the transmission belt to rotate a rotating rod and a triangular extrusion arm plate on the surface of a support frame. When the triangular extrusion arm plate slides on the bottom surface of the screen plate, it extrudes the antimony raw materials accumulated on the top surface of the screen plate, causing the antimony raw materials to gradually slide down from the surface of the screen plate into the interior of the low-temperature smelting and purification tank. This achieves the effect of using the transmission belt to rotate the rotating rod, allowing the antimony raw materials on the top surface of the screen plate to gradually slide downwards and fall into the low-temperature smelting and purification tank, reducing the blockage of antimony raw materials on the top surface of the screen plate. 2. The method and apparatus for low-temperature smelting of antimony resources according to the present invention, when the rotating rod drives the triangular extrusion arm plate to rotate on the bottom surface of the screen plate, the inclined surface on the top surface of the triangular extrusion arm plate will slide on the bottom surface of the swing plate. As the triangular extrusion arm plate moves continuously, it will lift the swing plate upward, and cause the conical pushing block on the top surface of the swing plate to lift upward from the inner side wall of the material drop trough. The spikes on the top surface of the conical pushing block will pierce the bottom surface of the antimony raw material and the antimony raw material accumulated on the top surface of the screen plate, and cause the antimony raw material to separate towards the periphery of the conical pushing block. At this time, a certain space will be generated between the material drop trough and the conical pushing block. The antimony raw material that slides down will pass through the space and fall into the low-temperature smelting and purification tank. This achieves the effect of relaxing and diverting the antimony raw material accumulated at the bottom under the continuous lifting and pushing of the triangular extrusion arm plate by the conical pushing block. 3. The method and apparatus for low-temperature smelting of antimony resources according to the present invention, when the antimony raw material continuously falls into the low-temperature smelting and purification tank, a heating device on the inner wall of the low-temperature smelting and purification tank is used to heat the antimony raw material at high temperature, so that the antimony raw material that enters the low-temperature smelting and purification tank first begins to be preheated. After the antimony raw material has completely entered the low-temperature smelting and purification tank, a pair of limit sliders are pulled back with the hydraulic rod, so that the bottom surface of the decomposition discharge cylinder can be away from the low-temperature smelting and purification tank, so as to avoid the high temperature generated when heating the antimony raw material inside the low-temperature smelting and purification tank causing the bottom surface of the decomposition discharge cylinder to soften and deform due to high temperature. 4. The low-temperature smelting method and apparatus for antimony resources described in this invention involves the formation of three layers inside the low-temperature smelting purification tank after secondary purification of the antimony raw material: slag floating on the top layer, antimony matte in the middle layer, and crude antimony and precious antimony at the bottom layer. At this time, four sets of motors on both sides of the support frame rotate a pair of transmission gear cylinders, causing the transmission gear cylinders to drive the limiting connecting rods and the low-temperature smelting purification tank to rotate on the surface of the support frame. As the low-temperature smelting purification tank tilts continuously, the slag floating on the top layer is poured into the impurity collection tank, thereby recovering the slag from the secondary purification of the antimony liquid. After the top layer of slag is completely cleaned, the impurity collection tank is replaced, and the antimony matte, crude antimony, and precious antimony inside the low-temperature smelting purification tank are recovered separately, achieving the effect of sequentially recovering the secondary purified antimony liquid and slag.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 9As shown, an antimony resource low-temperature smelting device according to an embodiment of the present invention includes a support frame 11 and a low-temperature smelting and purification tank 12 detachably mounted on the outer surface of the support frame 11. A limiting slider 13 is movably connected to the top outer surface of the support frame 11. A limiting track 111 is provided on the top surface of the support frame 11 and movably sleeved on the inner wall of the limiting slider 13. Two sets of hydraulic rods 113 are fixedly installed on the back of the support frame 11. Two sets of motors 136 are fixedly installed on the top surface of the limiting slider 13 and at the two side edges. Two sets of transmission tracks 137 are movably sleeved on the outer surface of the output ends of the two sets of motors 136. A support frame 138 is provided on the top surface of the limiting slider 13 and at the other two side edges. A rotating rod 1311 is movably sleeved on the outer surface of the support frame 138. A distribution rod is fixedly installed on one side surface of the support frame 138. The material discharge cylinder 139 has a triangular extrusion arm plate 1312 fixedly connected to the bottom end of the rotating rod 1311, which is movably connected to the bottom surface of the screen plate 1310. Two sets of hydraulic rods 132 are fixedly installed on the top surface of the limiting slider 13 and at the two side edges. Two sets of limiting support rods 133 are fixedly installed on the top surface of the limiting slider 13 and at the two side edges of the hydraulic rods 132. A lifting push plate 134 is fixedly connected to the output end of the hydraulic rods 132 and is movably sleeved on the outer surface of the limiting support rods 133. The bottom surface of the support frame 138 is fixedly connected to the top surface of the lifting push plate 134. A support frame 135 is fixedly connected to the top surface of the lifting push plate 134 and at the two side edges. The bottom surface of the motor 136 is fixedly installed on the top surface of the support frame 135. A push plate 131 is fixedly installed on the top outer surface of the limiting slider 13.

[0023] Antimony raw material, mixed with raw agent, flux, and desulfurizing agent, is placed into the interior of the differentiation feeding cylinder 139, causing the antimony raw material to accumulate on the surface of the screen plate 1310. At this time, hydraulic rod 113 pushes the limiting slider 13, causing it to slide on the surface of the limiting track 111, moving the differentiation feeding cylinder 139 to the top edge of the low-temperature smelting and purification tank 12. Motor 136 then drives the transmission track 137, causing it to rotate the rotating rod 1311 and the triangular extrusion arm plate 1312 on the surface of the support frame 138. When the triangular extrusion arm plate 1312 slides on the bottom surface of the screen plate 1310... The conical pushing block a3 on the top surface of the swing plate a2 will be pushed upward, and the conical pushing block a3 will extend through the inner wall of the material drop chute a1 to the top surface of the screen plate 1310. After passing the screen plate 1310, it will squeeze the bottom layer of antimony raw material accumulated on the top surface of the screen plate 1310, and cause the antimony raw material to gradually slide down from the surface of the screen plate 1310 into the interior of the low temperature smelting and purification tank 12. This achieves the effect of using the transmission track 137 to rotate the rotating rod 1311, so that the antimony raw material on the top surface of the screen plate 1310 can gradually slide downward and fall into the interior of the low temperature smelting and purification tank 12, thereby reducing the blockage of antimony raw material on the top surface of the screen plate 1310.

[0024] like Figure 4 - Figure 6 and Figures 8 to 9 As shown, the outer surface of the bottom end of the rotating rod 1311 is movably sleeved at the center position of the screen plate 1310, and the outer surfaces of the two sets of transmission tracks 137 are movably adjusted at the top edge position of the rotating rod 1311. A material drop groove a1 is provided on the surface of the screen plate 1310, and a swing plate a2 is fixedly connected to the bottom surface of the screen plate 1310. A conical push block a3 is fixedly installed on the top surface of the swing plate a2 and is movably sleeved on the inner wall of the material drop groove a1.

[0025] When the rotating rod 1311 drives the triangular extrusion arm plate 1312 to rotate on the bottom surface of the screen plate 1310, the inclined surface on the top surface of the triangular extrusion arm plate 1312 slides on the bottom surface of the swing plate a2. As the triangular extrusion arm plate 1312 moves continuously, it lifts the swing plate a2 upward, causing the conical pushing block a3 on the top surface of the swing plate a2 to lift upward from the inner wall of the material drop trough a1. The spikes on the top surface of the conical pushing block a3 pierce the bottom surface of the antimony raw material and the antimony raw material accumulated on the top surface of the screen plate 1310, causing the antimony raw material to separate towards the periphery of the conical pushing block a3. At this time, a certain space is generated between the material drop trough a1 and the conical pushing block a3. The antimony raw material that slides down will pass through the space and fall into the low temperature smelting and purification tank 12. This achieves the effect of relaxing and diverting the antimony raw material accumulated at the bottom by using the conical pushing block a3 under the continuous lifting and pushing of the triangular extrusion arm plate 1312.

[0026] like Figures 1 to 9 As shown, an impurity collection trough 118 is movably connected to the bottom surface of the support frame 11 and the bottom edge of the output end of the low temperature smelting and purification tank 12. The output end of the hydraulic rod 113 is fixedly connected to the surface of the push plate 131. A screen plate 1310 is provided on the inner wall of the dispersing and dropping cylinder 139.

[0027] As the antimony raw material continuously falls into the low-temperature smelting and purification tank 12, the heating device on the inner wall of the low-temperature smelting and purification tank 12 heats the antimony raw material at high temperature, so that the antimony raw material that enters the low-temperature smelting and purification tank 12 first begins to be preheated. After the antimony raw material has completely entered the low-temperature smelting and purification tank 12, the hydraulic rod 113 pulls back the limiting slider 13, so that the bottom surface of the differentiation dropping cylinder 139 can be away from the low-temperature smelting and purification tank 12. This avoids the high temperature generated when heating the antimony raw material inside the low-temperature smelting and purification tank 12 from causing the bottom surface of the differentiation dropping cylinder 139 to soften and deform due to high temperature.

[0028] like Figures 1 to 4 As shown, a second support frame 112 is fixedly installed on the top surface of the support frame 11, which is located on the outer surface of the hydraulic rod 113. Four sets of motors 114 are symmetrically fixedly installed on the two sides of the support frame 11. A limiting lap rod 115 is movably sleeved on the outer surface of the support frame 11. A transmission toothed cylinder 116 is provided on the outer surface of the limiting lap rod 115. The output end of the motor 114 is threaded and movably sleeved on the outer surface of the transmission toothed cylinder 116. A limiting collar 117 is fixedly installed on the other end of the limiting lap rod 115, which is located on the outer surface of the low-temperature smelting and purification tank 12.

[0029] After secondary purification, the antimony raw material forms three layers inside the low-temperature smelting purification tank 12: slag floating on the top layer, antimony matte in the middle layer, and crude and precious antimony at the bottom layer. At this time, four sets of motors 114 on both sides of the support frame 11 rotate the transmission gear cylinder 116, causing the transmission gear cylinder 116 to drive the limit connecting rod 115 and the low-temperature smelting purification tank 12 to rotate on the surface of the support frame 11. As the low-temperature smelting purification tank 12 tilts continuously, the slag floating on the top layer is poured into the impurity collection tank 118, thereby recovering the slag from the secondary purification of antimony liquid. After the top layer of slag is completely cleaned, the impurity collection tank 118 is replaced, and the antimony matte, crude antimony, and precious antimony inside the low-temperature smelting purification tank 12 are recovered separately, achieving the effect of sequentially recovering the secondary purification of antimony liquid and slag.

[0030] Example 2: As Figure 10 As shown, an embodiment of the present invention provides a method for low-temperature smelting of antimony resources, comprising the following steps: S1. The antimony raw material after one purification is crushed, and the crushed antimony raw material is dried and preliminarily removed. S2. Add mixing agent, flux and desulfurizing agent to the inside of the antimony particles after the first impurity removal, and guide the antimony particles into the inside of the conveying tank; S3. At this time, the delivery device moves the conveying tank to the top edge of the low temperature smelting and purification tank, and the triangular extrusion arm plate shakes the antimony raw material inside the low temperature smelting and purification tank evenly down in sequence. S4. When the antimony raw material is heated at high temperature, the mixed raw materials, flux and desulfurizing agent adhering to the surface of the antimony raw material will cause the residue inside the antimony raw material to be discharged, and the low temperature smelting and purification tank will carry out secondary heating and purification treatment of the antimony raw material. S4. After the antimony raw material is purified for the second time, the slag floating on the top layer is collected and the remaining antimony raw material is recycled.

[0031] Working principle: Antimony raw material mixed with raw agent, flux, and desulfurizing agent is placed into the interior of the differentiation feeding cylinder 139, causing the antimony raw material to accumulate on the surface of the screen plate 1310. At this time, hydraulic rod 113 pushes the limiting slider 13, causing the limiting slider 13 to slide on the surface of the limiting track 111, moving the differentiation feeding cylinder 139 to the top edge of the low-temperature smelting and purification tank 12. At this time, motor 136 drives the transmission track 137, causing the transmission track 137 to drive the rotating rod 1311 and the triangular extrusion arm plate 1312 on the support frame 1. The triangular extrusion arm plate 1312 rotates on the surface of the screen plate 1310. When the triangular extrusion arm plate 1312 slides on the bottom surface of the screen plate 1310, it extrudes the antimony raw material accumulated on the top surface of the screen plate 1310 and causes the antimony raw material to gradually slide down from the surface of the screen plate 1310 into the interior of the low temperature smelting and purification tank 12. This achieves the effect of using the transmission track 137 to rotate the rotating rod 1311, so that the antimony raw material on the top surface of the screen plate 1310 can gradually slide down and fall into the interior of the low temperature smelting and purification tank 12, thereby reducing the blockage of the antimony raw material on the top surface of the screen plate 1310. When the rotating rod 1311 drives the triangular extrusion arm plate 1312 to rotate on the bottom surface of the screen plate 1310, the inclined surface on the top surface of the triangular extrusion arm plate 1312 will slide on the bottom surface of the swing plate a2. As the triangular extrusion arm plate 1312 moves continuously, it will lift the swing plate a2 upward, and cause the conical pushing block a3 on the top surface of the swing plate a2 to lift upward from the inner side wall of the discharge trough a1. The spikes on the top surface of the conical pushing block a3 will pierce the bottom surface of the antimony raw material and the antimony raw material accumulated on the top surface of the screen plate 1310, and cause the antimony raw material to separate towards the periphery of the conical pushing block a3. At this time, a certain space will be generated between the discharge trough a1 and the conical pushing block a3. The antimony raw material that slides down will pass through the space and fall into the low temperature smelting and purification tank 12. This achieves the effect of relaxing and diverting the antimony raw material accumulated at the bottom by using the conical pushing block a3 under the continuous lifting and pushing of the triangular extrusion arm plate 1312. As the antimony raw material continuously falls into the low-temperature smelting and purification tank 12, the heating device on the inner wall of the low-temperature smelting and purification tank 12 heats the antimony raw material at high temperature, so that the antimony raw material that enters the low-temperature smelting and purification tank 12 first begins to be preheated. After the antimony raw material has completely entered the low-temperature smelting and purification tank 12, the hydraulic rod 113 pulls back the limiting slider 13, so that the bottom surface of the differentiation dropping cylinder 139 can be away from the low-temperature smelting and purification tank 12, so as to avoid the high temperature generated when heating the antimony raw material inside the low-temperature smelting and purification tank 12 from causing the bottom surface of the differentiation dropping cylinder 139 to soften and deform due to high temperature. After secondary purification, the antimony raw material forms three layers inside the low-temperature smelting purification tank 12: slag floating on the top layer, antimony matte in the middle layer, and crude and precious antimony at the bottom layer. At this time, four sets of motors 114 on both sides of the support frame 11 rotate the transmission gear cylinder 116, causing the transmission gear cylinder 116 to drive the limit connecting rod 115 and the low-temperature smelting purification tank 12 to rotate on the surface of the support frame 11. As the low-temperature smelting purification tank 12 tilts continuously, the slag floating on the top layer is poured into the impurity collection tank 118, thereby recovering the slag from the secondary purification of antimony liquid. After the top layer of slag is completely cleaned, the impurity collection tank 118 is replaced, and the antimony matte, crude antimony, and precious antimony inside the low-temperature smelting purification tank 12 are recovered separately, achieving the effect of sequentially recovering the secondary purification of antimony liquid and slag.
