[0002] In the copper smelting process, a large amount of smelting slag is usually generated, which contains a certain amount of valuable metals, such as zinc and lead. In order to effectively recover and utilize these valuable metals, especially zinc, it is necessary to develop an efficient process and equipment that can effectively separate and recover zinc from copper smelting slag.

Detailed Implementation

[0040] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] Please see Figures 1 to 16As shown, the present invention provides a technical solution: a device for separating and recovering zinc from copper smelting slag, comprising a recovery component 1, wherein the recovery component 1 is provided with a driving component 2, an upper fastening component 3, a lower fastening component 4, and a connecting component 5. The recovery component 1 includes an upper support frame 110 and a lower support frame 111.

The drive assembly 2 includes a push rod 202, and the first end of a rotating rod 203 is rotatably connected to the push rod 202. The second end of the rotating rod 203 is provided with a through hole. The upper fastening assembly 3 includes a support slide plate 301 and a trigger block 307. The first end of the support slide plate 301 is slidably connected to the bracket 109, and the second end of the support slide plate 301 is provided with an inclined surface. The first end of the trigger block 307 is provided with an inclined surface. On the other hand, the second end of the trigger block 307 is slidably connected to the rear connecting rod 310, the first end of the rear connecting rod 310 is fixedly connected to the upper support frame 110, the second end of the rear connecting rod 310 is rotatably connected to the first end of the rotating shaft 313, the second end of the rotating shaft 313 is fixedly connected to the first end of the front connecting rod 311, and the second end of the front connecting rod 311 is slidably connected to the groove of the push rod 202. The lower fastening assembly 4 includes a connecting inclined block 403, and a sliding plate 402 is fixedly connected to the connecting inclined block 403. 2. The sliding ring 401 is slidably connected to the sliding ring 401, and the sliding ring 401 is also fixedly connected to the lower support frame 111. The connecting component 5 includes a lower connecting rod 507. The first end of the lower connecting rod 507 is rotatably connected to the lower shaft 118, and the second end of the lower connecting rod 507 is slidably connected to the outer frame 501. An upper limit plate 509 is also fixedly connected to the lower connecting rod 507, and a lower limit plate 508 is also slidably connected to the lower connecting rod 507. Both the lower limit plate 508 and the upper limit plate 509 are provided with inclined surfaces, and the inclined surfaces are in opposite directions.

[0042] like Figure 1 As shown, the drive assembly 2, the upper fastening assembly 3, the lower fastening assembly 4, and the connecting assembly 5 are all provided in two sets and are symmetrically distributed on both sides of the inner furnace 102.

[0043] The recycling assembly 1 also includes a pipe 104, the first end of which is fixedly connected to the upper cover 103, the second end of which is fixedly connected to the first end of the filter box 105, the first end of the condenser tube 106 is fixedly connected to the second end of the filter box 105, the second end of the condenser tube 106 is fixedly connected to the base 108, and a collection box 107 is slidably connected to the second end of the condenser tube 106. The first end of the upper telescopic rod 116 is fixedly connected to the upper support frame 110, the second end of the upper telescopic rod 116 is fixedly connected to the base 108, and an upper shaft 114 is fixedly connected to the upper support frame 110. The first point of the vertical push rod 113 is fixedly connected to the upper shaft 114, and the second end of the vertical push rod 113 is fixedly connected to the crossbar 502.

[0044] The lower support frame 111 is also rotatably connected to the first end of the lower telescopic rod 115, and the second end of the lower telescopic rod 115 is fixedly connected to the base 108. The base 108 is fixedly connected to the fuming furnace 101, and the fuming furnace 101 is provided with a groove for the lower support frame 111 to slide. The base 108 is also fixedly connected to the first end of the rear telescopic rod 117, and the second end of the rear telescopic rod 117 is fixedly connected to the upper support frame 110.

[0045] like Figure 3 and Figure 15 As shown, during use, the copper smelting slag to be treated, along with the required combustion agent and oxidant, are first placed into the inner furnace 102. Then, the upper cover 103 is used to close the inner furnace 102, and the furnace is calcined at high temperature through the heating device inside the fuming furnace 101. As a result, the zinc compounds (usually zinc oxide) undergo a thermal reduction reaction and are converted into gaseous zinc oxide (ZnO). The gaseous zinc oxide is discharged through the flue. The flue gas may also contain other impurities, so it needs to be filtered through the filter box 105 to remove impurities. Finally, it is condensed through the condenser tube 106, causing the zinc oxide to condense into fine particles or liquid, which are then collected through the collection box 107.

[0046] After the copper smelting slag from this batch is processed, the residue needs to be poured out before a new batch is added.

[0047] The drive assembly 2 further includes a reset plate 204. The first end of the reset plate 204 is slidably connected to the convex shaft of the push rod 202. The second end of the reset plate 204 is fixedly connected to the first end of the reset slider 206. The second end of the reset slider 206 is slidably connected to the push rod 202 and the rotating rod 203. A reset push block 205 is also slidably connected to the push rod 202. The reset push block 205 is provided with a push block, which corresponds to the through hole on the rotating rod 203.

[0048] like Figure 5 and Figure 6As shown, push rod 202 is fixedly connected to the output rod of cylinder 201, and cylinder 201 is fixedly connected to base 108. In operation, the push rod 202 is moved up and down by the cylinder 201. The upper support frame 110 moves up and down with the push rod 202 via the sliding groove at the end of the push rod 202 near the upper fastening component 3. When the push rod 202 moves down a certain distance, that is, when the upper cover 103 and the inner furnace 102 are about to be fastened, the through hole on the rotating rod 203 contacts the lower fastening component 4, so that the connecting wedge 403 is inserted into the rotating rod 203. Then, it continues to move down, and the connecting wedge 403 is pushed out through the inclined surface of the connecting wedge 403. The through hole on the rotating rod 203 moves away from the connecting wedge 403. Then, when the copper smelting slag of this batch is finished and the push rod 202 moves up, the connecting wedge 403 is inserted into the through hole on the rotating rod 203 again. Thus, the connecting wedge 403 drives the lower support frame 111 and the inner furnace 102 to move up to perform the tilting process.

[0049] The upper cover 103 and the inner furnace 102 are fastened together in a large-tube-within-a-small-tube configuration, meaning the inner diameter of the upper cover 103 is approximately equal to the outer diameter of the inner furnace 102. This minimizes heat and flue gas loss when the upper cover 103 and the inner furnace 102 are fastened together. After fastening, the upper cover 103 can continue to move downwards a certain distance.

[0050] The first end of the first sliding shaft 302 is fixedly connected to the support slide plate 301. The second end of the first sliding shaft 302 is slidably connected to the bracket 109. The first end of the intermediate slide plate 304 is also slidably connected to the first sliding shaft 302. The first end of the second sliding shaft 305 is fixedly connected to the second end of the intermediate slide plate 304. The first end of the first spring 303 is also fixedly connected to the first end of the intermediate slide plate 304. The second end of the first spring 303 is fixedly connected to the support slide plate 301. The second end of the second sliding shaft 305 is slidably connected to the bracket 109. The second end of the second sliding shaft 305 is also rotatably connected to the first end of the intermediate connecting rod 306. The second end of the intermediate connecting rod 306 is rotatably connected to the trigger block 307.

[0051] A long slide bar 308 is also fixedly connected to the trigger block 307. The first end of the long slide bar 308 is slidably connected to the slide groove of the upper limit block 312, and the second end of the long slide bar 308 is slidably connected to the fixed slider 314. The fixed slider 314 is fixedly connected to the upper support frame 110. The first end of the third spring 309 is fixedly connected to the fixed slider 314, and the second end of the third spring 309 is fixedly connected to the trigger block 307.

[0052] like Figure 7 and Figure 12As shown, a torsion spring is fixedly connected to the first end of the rotating shaft 313, and the second end of the torsion spring is fixedly connected to the rear connecting rod 310 on a side away from the front connecting rod 311. The second end of the front connecting rod 311 is provided with an arc surface, which facilitates the second end of the front connecting rod 311 to move out of the groove on the push rod 202 when the front connecting rod 311 rotates.

[0053] When in use, when the top cover 103 is in the initial position, the support slide plate 301 is not close to the rear connecting rod 310, while the trigger block 307 is close to the upper limit block 312. The first end of the long slide rod 308 on the upper limit block 312 is located inside the upper limit block 312, and the third spring 309 on the second end of the long slide rod 308 is in a relaxed state, that is, it is not compressed. The torsion spring on the rotating shaft 313 is not twisted. Thus, the rear connecting rod 310 and the front connecting rod 311 are collinear, which is equivalent to a straight rod. Therefore, when the push rod 202 moves up and down, it can drive the front connecting rod 311 through the slide groove, thereby driving the top cover 103 to move up and down.

[0054] When the push rod 202 moves the upper cover 103 upward to the initial position, and the inner furnace 102 needs to be tilted, the push rod 202 continues to move upward, causing the upper cover 103 to move upward a distance further. This causes the upper stop rod 315 to act on the inclined surface of the trigger block 307, squeezing the trigger block 307 to slide towards the fixed slider 314 on the rear connecting rod 310. This pulls the second end of the intermediate connecting rod 306, and the first end of the intermediate connecting rod 306 pulls the intermediate sliding plate 304 to slide towards the rear connecting rod 310 on the first sliding shaft 302, squeezing the first spring 303. The elastic force of the first spring 303 pushes the support sliding plate 301 to slide on the bracket 109, causing the support sliding plate 301 to enter below the rear connecting rod 310, thereby supporting the rear connecting rod 310. Furthermore, when the trigger block 307 moves, it causes the long slide bar 308 to slide on the upper limit block 312 and the fixed slider 314, and compresses the third spring 309. When the first end of the long slide bar 308 completely leaves the upper limit block 312, that is, when the support slide plate 301 moves below the rear connecting rod 310 and can support the rear connecting rod 310, at this time, the front connecting rod 311 and the rear connecting rod 310 are no longer restricted by the long slide bar 308. The front connecting rod 311 and the rear connecting rod 310 are no longer equivalent to a straight rod. As a result, the upper cover 103 and the rear connecting rod 310 and other parts move downwards due to gravity and fall onto the support. On the skateboard 301, the support skateboard 301 is supported, and the second end of the front connecting rod 311 is pulled by the rear connecting rod 310, so that the front connecting rod 311 rotates around the rotating shaft 313 and twists the torsion spring on the rotating shaft 313, so that the second end of the front connecting rod 311 moves away from the push rod 202. The second end of the front connecting rod 311 rests against the side of the push rod 202 near the front connecting rod 311, and the first end of the long sliding rod 308 abuts against the side of the upper limit block 312 away from the front connecting rod 311, so that the elastic force of the third spring 309 and the first sliding shaft 302 is fixed, thereby maintaining the position of the upper cover 103.

[0055] During the above process, the inner furnace 102 is tilted. After the tilting is completed, the push rod 202 is moved downward. The groove on the push rod 202 contacts the second end of the front connecting rod 311 again. Under the action of the torsion spring on the rotating shaft 313, the front connecting rod 311 rotates, so that the second end of the front connecting rod 311 enters the groove on the push rod 202. When the front connecting rod 311 and the rear connecting rod 310 are collinear, the spring force of the third spring 309 and the first sliding shaft 302 pushes the trigger block 307 and the support slide plate 301 to reset. That is, the support slide plate 301 moves away from the rear connecting rod 310. The first end of the long slide bar 308 on the trigger block 307 enters the upper limit block 312 again, so that the rear connecting rod 310 and the front connecting rod 311 are restricted, making them equivalent to a straight rod. Then, the push rod 202 controls the movement of the upper cover 103.

[0056] The lower fastening assembly 4 also includes a central slide rod 404, which is fixedly connected to the connecting inclined block 403. A central spring 405 is provided on the central slide rod 404. The first end of the central spring 405 is fixedly connected to the connecting inclined block 403, and the second end of the central spring 405 is fixedly connected to the lower support frame 111. An inclined surface is provided on the end of the connecting inclined block 403 near the push rod 202.

[0057] like Figure 9 and Figure 10 As shown, the connecting inclined block 403 is equipped with multiple sets of sliding plates 402. During use, when the push rod 202 moves downwards, the through hole on the rotating rod 203 passes through the connecting inclined block 403 and presses against the inclined surface of the connecting inclined block 403, causing the connecting inclined block 403 to push the sliding plates 402 to slide on the sliding ring 401. The connecting inclined block 403 also presses against the central spring 405, and the central sliding rod 404 slides on the lower support frame 111. Continuing to move the push rod 202 causes the rotating rod 203 to move away from the connecting inclined block 403. After the reaction is complete, the push rod 202 is controlled to move upwards, and the through hole of the rotating rod 203 contacts the connecting inclined block 403. The connecting inclined block 403 enters the through hole, so that when the push rod 202 moves upwards, it drives the connecting inclined block 403 to move upwards, thereby moving the lower support frame 111 and the inner furnace 102 through the sliding plates 402 and the sliding ring 401.

[0058] When it is necessary to disengage the rotating rod 203 from the connecting wedge block 403, manually press the reset push block 205. The reset push block 205 pushes the connecting wedge block 403 away from the connecting wedge block 403. At the same time, control the push rod 202 to move upward, so that the connecting wedge block 403 can disengage from the through hole on the rotating rod 203.

[0059] The first end of the vertical slide rod 505 is slidably connected to the horizontal frame 502. The first end of the horizontal slide rod 504 is slidably connected to the second end of the vertical slide rod 505. The second end of the horizontal slide rod 504 is slidably connected to the outer frame 501. The first end of the horizontal return spring 506 is fixedly connected to the second end of the horizontal slide rod 504. The second end of the horizontal return spring 506 is fixedly connected to the vertical slide rod 505. The first end of the trigger rod 503 is also fixedly connected to the vertical slide rod 505. The second end of the trigger rod 503 is slidably connected to the outer frame 501, and the second end of the trigger rod 503 is provided with an inclined surface.

[0060] like Figures 13 to 16 As shown, the outer frame 501 rests on the upper shaft 114 due to gravity, and when the upper part of the outer frame 501 contacts the upper shaft 114, the lower part of the outer frame 501 also contacts the second end of the lower connecting rod 507.

[0061] When the upper support frame 110 moves downward, due to gravity, the outer frame 501 moves along with the upper shaft 114 on the upper support frame 110. When the bottom of the outer frame 501 contacts the base 108, the outer frame 501 no longer moves downward with the upper support frame 110 due to the supporting force of the base 108. Therefore, when the upper support frame 110 moves downward, it pushes the horizontal frame 502 downward through the upper shaft 114 and the vertical push rod 113, thereby controlling the horizontal slide rod 504 and the trigger rod 503 to slide downward on the outer frame 501. Then, when the upper support frame 110 drives the upper cover 103 to engage with the inner furnace 10, During process 2, the horizontal frame 502 controls the trigger rod 503 to contact the upper limit plate 509 via the vertical slide rod 505. The inclined surface of the upper limit plate 509 presses the trigger rod 503, thereby pushing the vertical slide rod 505 outward on the horizontal frame 502 and pulling the transverse return spring 506 on the horizontal slide rod 504, continuing its movement. When the trigger rod 503 leaves the upper limit plate 509, it returns to its original position under the action of the transverse return spring 506. At this time, the upper cover 103 engages with the inner furnace 102, and the trigger rod 503 is positioned between the upper limit plate 509 and the lower limit plate 508. After the reaction is complete, when the upper cover 103 is moved upward, the trigger rod 503 pushes the upper limit plate 509, which in turn pushes the lower shaft 118 and the lower support frame 111 upward via the upper limit plate 509 and the lower connecting rod 507. Finally, the inner furnace 102 slides upward on the fumigation furnace 101 and leaves the fumigation furnace 101.

[0062] During the upward movement of the lower support frame 111 and the upper support frame 110, the lower telescopic rod 115, the upper telescopic rod 116, and the rear telescopic rod 117 are pulled respectively. When the upper cover 103 returns to the initial position and continues to move upward, the upper cover 103 is supported. At this time, the lower telescopic rod 115, the upper telescopic rod 116, and the rear telescopic rod 117 have reached their limits and cannot be pulled any further. Furthermore, springs are provided on the lower telescopic rod 115, the upper telescopic rod 116, and the rear telescopic rod 117. The spring on the lower telescopic rod 115 is in a relaxed state when the inner furnace 102 is inside the fuming furnace 101, while the springs on the upper telescopic rod 116 and the rear telescopic rod 117 are in a relaxed state when the upper cover 103 is in the initial position. That is, at this time, the spring on the lower telescopic rod 115 is in a stretched state, while the springs on the upper telescopic rod 116 and the rear telescopic rod 117 are in a slightly stretched state. Therefore, when push rod 202 continues to move upward, it pushes the end of lower support frame 111 away from lower telescopic rod 115 upward through connecting wedge block 403. At this time, upper support frame 110 no longer moves with push rod 202, outer frame 501 rests on upper shaft 114, and lower end of outer frame 501 contacts the second end of lower connecting rod 507. Under the action of spring on lower telescopic rod 115, the end of lower support frame 111 near lower telescopic rod 115 is always under downward force, but because the lower end of outer frame 501 and The lower connecting rod 507 supports the lower shaft 118, preventing the lower support frame 111 from being driven by the spring on the lower telescopic rod 115. Thus, when the push rod 202 moves upward, causing the end of the lower support frame 111 away from the lower telescopic rod 115 to move upward, the spring on the lower telescopic rod 115 can pull the end of the lower support frame 111 near the lower telescopic rod 115 downward, causing the lower support frame 111 to rotate counterclockwise on the lower shaft 118, causing the inner furnace 102 to tilt and pour out the residue inside the inner furnace 102.

[0063] When it is necessary to disengage the trigger rod 503 from the lower limit plate 508 and the upper limit plate 509, the push rod 202 controls the upper cover 103 to engage with the inner furnace 102. Then, the push rod 202 continues to move downward, thereby pushing the horizontal frame 502 through the vertical push rod 113. Through the inclined surface on the trigger rod 503, when the trigger rod 503 contacts the lower limit plate 508, the trigger rod 503 pushes the vertical sliding rod 505 to slide on the horizontal frame 502, thereby causing the trigger rod 503 to fall below the lower limit plate 508. Then, the push rod 202 is controlled to move upward, thereby triggering... The lever 503 pushes the lower limit plate 508 to slide on the lower connecting rod 507. When the lower limit plate 508 contacts the upper limit plate 509, the trigger lever 503 can no longer push the lower limit plate 508. Thus, through the inclined surface of the lower limit plate 508, the trigger lever 503 pushes the vertical sliding rod 505 to slide on the horizontal frame 502 and then continues to move upward. The trigger lever 503 moves along the side of the lower limit plate 508 and the upper limit plate 509. The trigger lever 503 disengages from the upper limit plate 509, so when the push rod 202 moves upward, it no longer drives the inner furnace 102 to move.

[0064] A process for separating and recovering zinc from copper smelting slag, comprising the following steps:

[0065] Step 1: Place the copper smelting slag to be recycled into the inner furnace 102, and add an appropriate amount of fuel and oxidant.

[0066] Step 2: Start cylinder 201 and control push rod 202 to move downward, thereby driving the lower support frame 111 and upper cover 103 to move downward through upper fastening assembly 3, so that upper cover 103 is fastened to inner furnace 102.

[0067] Step 3: As the lower support frame 111 moves downward, the trigger rod 503 is pushed by the vertical push rod 113 to lock between the lower limit plate 508 and the upper limit plate 509.

[0068] Step 4: Start the heating device inside the fuming furnace 101 to calcine the copper smelting slag in the inner furnace 102 at high temperature, producing flue gas mixed with gaseous zinc oxide.

[0069] Step 5: The flue gas enters the filter box 105 through the pipe 104 for filtration.

[0070] Step Six: Then, the zinc oxide is condensed through the condenser tube 106, causing it to condense into fine particles or liquid, which fall into the collection box 107.
