Among them, the accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principle of the present invention, and are not used to limit the scope of the present invention.

[0020] Such as Figures 1-5As shown in the figure, an embodiment of the present invention provides a ternary sulfide roasting system, which includes: a first sagger transport line 1, a second sagger transport line 2, at least two calcination devices 3, and a sagger picking and placing mechanism 4. The first sagger transport line 1 is used to transport saggers, and the second sagger transport line 2 is used to transport saggers. Each calcination device 3 is docked with the first sagger transport line 1 and the second sagger transport line 2, and is used to calcine the saggers transported by the first sagger transport line 1 or the second sagger transport line 2 and send them to the first sagger transport line 1 or the second sagger transport line 2. The sagger picking and placing mechanism 4 straddles the first sagger transport line 1 and the second sagger transport line 2, and is used to place the saggers to be calcined on the first sagger transport line 1 or the second sagger transport line 2, and take out the saggers that have been calcined on the first sagger transport line 1 or the second sagger transport line 2.

[0021] In the present invention, a first sagger transport line 1, a second sagger transport line 2, and at least two calcination devices 3 are provided. Both ends of the calcination device 3 can feed and discharge materials. Both the first sagger transport line 1 and the second sagger transport line 2 can transport saggers. Each calcination device 3 can calcine saggers. Thus, the entire ternary sulfide roasting system can form multiple operation modes to meet various production requirements.

[0022] In addition, in the normal state, multiple calcination devices 3 can work simultaneously, thereby accelerating the calcination speed per unit time and reducing the waiting time of the uncalcined saggers on the first sagger transport line 1 and the second sagger transport line 2.

[0023] Specifically, the first sagger transport line 1 includes a first transport track 11, a first slider 12, and a first sagger bearing plate 13. The first slider 12 is arranged on the first transport track 11 and can actively slide along the first transport track 11 and stop at any position during its movement, and the first sagger bearing plate 13 is fixed on the first slider 12 for bearing saggers.

[0024] Furthermore, when the first slider 12 moves along the first transport track 11, it has a first picking and placing position where the first sagger bearing plate 13 is in the picking and placing area and first docking positions where the first sagger bearing plate 13 is respectively docked with each calcination device 3; the first slider 12 can switch between the first position and multiple first docking positions.

[0025] Further, a first pusher assembly 14 is provided on the first crucible carrier plate 13. The first pusher assembly 14 has a pusher end for pushing the crucible, and is used to push the crucible to move between the calcination device 3 and the first crucible carrier plate 13 when the first crucible carrier plate 13 is docked with the calcination device 3.

[0026] Further, a first groove 131 for accommodating the first pusher assembly 14 is formed on the first crucible carrier plate 13. The first pusher assembly 14 includes a first pusher sliding rod 141, a first pusher slider 142, a first pusher cylinder 143 and a first pusher plate 144. The first pusher sliding rod 141 is embedded in the first groove 131. The first pusher slider 142 is slidably connected to the first pusher sliding rod 141. The first pusher cylinder 143 is fixed on the first pusher slider 142. The first pusher plate 144 is fixed on the movable end of the first pusher cylinder 143. The movable end of the first pusher cylinder 143 extends and retracts to drive the first pusher plate 144 to retract into the first groove 131 or protrude relative to the first groove 131.

[0027] According to the above structure, the first pusher assembly 14 can push the crucible from the first crucible carrier plate 13 to the calcination device 3, and can also push the crucible from the calcination device 3 to the first crucible carrier plate 13, so as to realize the movement of the crucible.

[0028] Specifically, the second crucible transportation line 2 includes a second transportation track 21, a second slider 22 and a second crucible carrier plate 23. The second slider 22 is arranged on the second transportation track 21 and can actively slide along the second transportation track 21 and stop at any position during its movement. The second crucible carrier plate 23 is fixed on the second slider 22 for carrying the crucible.

[0029] Further, when the second slider 22 moves along the second transportation track 21, it has a second pick-up and discharge position where the second crucible carrier plate 23 is in the pick-up and discharge area and a second docking position where the second crucible carrier plate 23 is docked with the calcination device 3. The second slider 22 can be switched between the second pick-up and discharge position and the second docking position.

[0030] Further, a second pusher assembly 24 is provided on the second crucible carrier plate 23. The second pusher assembly 24 has a pusher end for pushing the crucible, and is used to push the crucible to move between the calcination device 3 and the second crucible carrier plate 23 when the second crucible carrier plate 23 is docked with the calcination device 3.

[0031] Furthermore, a second groove 231 for accommodating the second pusher assembly 24 is formed in the second crucible carrier plate 23. The second pusher assembly 24 includes a second pusher sliding rod 241, a second pusher slider 242, a second pusher cylinder 243, and a second pusher plate 244. The second pusher sliding rod 241 is embedded in the second groove 231. The second pusher slider 242 is slidably connected to the second pusher sliding rod 241. The second pusher cylinder 243 is fixed on the second pusher slider 242. The second pusher plate 244 is fixed on the movable end of the second pusher cylinder 243. The movable end of the second pusher cylinder 243 extends and retracts to drive the second pusher plate 244 to retract into the second groove 231 or protrude relative to the second groove 231.

[0032] According to the above structure, the second pusher assembly 24 can push the crucible from the second crucible carrier plate 23 to the calcination device 3, and can also push the crucible from the calcination device 3 to the second crucible carrier plate 23, so as to realize the movement of the crucible.

[0033] Specifically, the calcination device 3 includes a calcination transport assembly 31 and a calcination furnace 32. The two ends of the calcination transport assembly 31 are respectively docked with the first crucible transport line 1 and the second crucible transport line 2. The calcination furnace 32 straddles the calcination transport assembly 31. The calcination transport assembly 31 is used to transport the crucibles transported by the first crucible transport line 1 or the second crucible transport line 2 to the calcination furnace 32 for calcination and transport the crucibles that have been calcined in the calcination furnace 32 to the first crucible transport line 1 or the second crucible transport line 2.

[0034] Furthermore, the calcination transport assembly 31 includes a sliding groove body 311 and a calcination pusher 312. The size of the sliding groove body 311 matches that of the crucible. The calcination pusher 312 is slidably embedded on the sliding groove body 311 and is used to push the crucible to move along the sliding groove body 311 and enter and exit the calcination furnace 32.

[0035] Furthermore, in some feasible solutions, since both ends of the calcination furnace 32 need to feed and discharge materials, two calcination pushers 312 are included, which are respectively arranged at both ends of the calcination furnace 32 and are used to push the crucible into or out of the calcination furnace 32 from both ends.

[0036] Further, a sliding rod is provided at the bottom of the sliding groove body 311. The calcination pusher 312 includes a calcination pusher slider 312a, a calcination pusher cylinder 312b, and a calcination pusher plate 312c. The calcination pusher slider 312a is slidably connected to the sliding rod. The calcination pusher cylinder 312b is fixed on the calcination pusher slider 312a. The calcination pusher plate 312c is fixed on the movable end of the calcination pusher cylinder 312b. The movable end of the calcination pusher cylinder 312b expands and contracts to drive the calcination pusher plate 312c to retract into the sliding groove body 311 or protrude relative to the sliding groove body 311.

[0037] Further, the calcination furnace 32 includes a furnace body 321 and a plurality of heating components. The furnace body 321 straddles the sliding groove body 311. Doors that can be opened and closed are provided at both ends of the furnace body 321 along the direction of the sliding groove body 311. The heating components are arranged on the inner wall of the furnace body 321. When the sagger enters the furnace body 321, the inside of the furnace body 321 is heated, thereby calcining the sagger.

[0038] Specifically, the sagger picking and placing mechanism 4 includes a material rack 41, a picking and placing slider 42, a picking and placing lifter 43, and a clamping jaw 44. The material rack 41 straddles the ends of the first sagger conveyor line 1 and the second sagger conveyor line 2. The picking and placing slider 42 is slidably connected to the material rack 41 and can stably stay at any position in its sliding stroke. The picking and placing lifter 43 is fixed on the picking and placing slider 42 and has a lifting end that lifts and lowers in the vertical direction. The clamping jaw 44 is fixed to the lifting end of the picking and placing slider 42 and is used to grab or release the sagger. The picking and placing slider 42 can slide along the material rack 41 and move back and forth above the first sagger conveyor line 1 and the second sagger conveyor line 2. Therefore, the sagger picking and placing mechanism 4 can choose to pick and place the materials on the first sagger conveyor line 1 or the materials on the second sagger conveyor line 2 according to the situation.

[0039] It can be understood that to improve the efficiency of picking and placing materials, the sagger picking and placing mechanism includes a plurality of the picking and placing sliders 42, the picking and placing lifters 43, and the clamping jaws 44, which can increase the speed of picking and placing materials.

[0040] It should be noted that the clamping jaw 44 includes a double-headed cylinder and a pair of clamping plates. The two movable ends of the double-headed cylinder are respectively fixed to the clamping plates. The two movable ends of the double-headed cylinder drive the clamping plates to move relative to each other, thereby realizing the functions of clamping and releasing the sagger.

[0041] In the present invention, it further includes a sagger feeding line 5 and a sagger discharging line 6. One end of the sagger feeding line 5 is arranged below the material rack 41, and the sagger feeding line 5 transports the saggers towards one end of the calcination device 3. One end of the sagger discharging line 6 is arranged below the material rack 41, and the sagger discharging line 6 transports the saggers towards one end away from the calcination device 3. The pick-and-place slider 42 can slide along the material rack 41, so that the pick-and-place lifting member 43 and the clamping jaws 44 move above the sagger feeding line 5, and grab the saggers fed by the sagger feeding line 5 to the first sagger transportation line 1 or the second sagger transportation line 2, or slide along the material rack 41, so that the pick-and-place lifting member 43 and the clamping jaws 44 move above the sagger discharging line 6, and grab the saggers that have completed calcination on the first sagger transportation line 1 or the second sagger transportation line 2 to the sagger discharging line 6.

[0042] Specifically, the sagger feeding line 5 includes a feeding line main body 51 and a blocking assembly 52. One end of the feeding line main body 51 is connected to the sagger pick-and-place mechanism 4. The blocking assembly 52 is arranged at one end of the feeding line main body 51 where it is docked with the sagger pick-and-place mechanism 4. The blocking assembly 52 has a blocking end that can move relative to the feeding line main body 51, and can block or release the saggers on the feeding line main body 51. The purpose of such a design is to block the saggers to be grabbed at the end of the feeding line main body 51, facilitating the sagger pick-and-place mechanism 4 to grab them.

[0043] Furthermore, the feeding line main body 51 is a conventional transportation line in the prior art, so it will not be elaborated here.

[0044] Furthermore, the blocking assembly 52 includes a pair of lifting and blocking air cylinders 521 and a blocking plate 522. The pair of lifting and blocking air cylinders 521 are fixed on both sides of the feeding line main body 51. The blocking plate 522 straddles the feeding line main body 51, and both ends are respectively fixed to the movable ends of the lifting and blocking air cylinders 521. The lifting and blocking air cylinders 521 drive the blocking plate 522 to lift and lower. When the movable ends of the lifting and blocking air cylinders 521 rise to the highest position, the distance between the blocking plate 522 and the feeding line main body 51 allows the saggers to pass through. When the movable ends of the lifting and blocking air cylinders 521 drop to the lowest position, the blocking plate 522 contacts the feeding line main body 51 to block the saggers on the feeding line main body 51.

[0045] Specifically, the sagger discharging line 6 is a conventional transportation line in the prior art, so it will not be elaborated here.

[0046] Thus, multiple calcination methods can be achieved: 1. When the first transport line of the sagger, the second transport line of the sagger, and each calcination device are all operating normally, the sagger loading and unloading mechanism places the saggers fed into the line on the first transport line of the sagger and the second transport line of the sagger. The first transport line of the sagger feeds the saggers into the calcination device for calcination. After the calcination is completed, it retreats to the first transport line of the sagger and is sent to the sagger loading and unloading mechanism for discharging and reloading; the saggers on the second transport line of the sagger enter the calcination device from the other side of the calcination device for calcination. After the calcination is completed, they are sent to the second transport line of the sagger and then to the sagger loading and unloading mechanism for discharging and reloading; thus, an alternating cycle is formed, significantly reducing the idling time in the calcination device and improving the utilization efficiency of the heat energy in the calcination device. In addition, since the calcination time of the calcination device is relatively long, in order to match the working efficiency of the calcination device with that of the first transport line of the sagger, the second transport line of the sagger, and the sagger loading and unloading mechanism, multiple calcination devices are provided, which can greatly improve the efficiency.

[0047] 2. When maintenance is required for the calcination device, multiple calcination devices can be alternately shut down for maintenance, so that the entire ternary sulfide roasting system can maintain operation and avoid shutdown; 3. In some special usage cases, the ternary sulfide roasting system can be changed to a one-way circulation mode; for example: the sagger loading and unloading mechanism places the saggers to be calcined on the first transport line of the sagger, the first transport line of the sagger sends the saggers to be calcined to the calcination device. After the calcination device completes the calcination, it sends the saggers to the second transport line of the sagger, and the second transport line of the sagger sends them to the placement location of the sagger loading and unloading mechanism, thus completing the one-way circulation; 4. When maintenance is required for the first transport line of the sagger or the second transport line of the sagger, the ternary sulfide roasting system is changed to a one-sided round-trip mode. For example: when the second transport line of the sagger is shut down for maintenance, the sagger loading and unloading mechanism places the saggers to be calcined on the first transport line of the sagger, the first transport line of the sagger sends the saggers to be calcined to the calcination device. After the calcination device completes the calcination, it sends the saggers to the first transport line of the sagger, and the second transport line of the sagger sends them to the placement location of the sagger loading and unloading mechanism for material taking and discharging, thus completing the one-sided round-trip feeding.

[0048] The beneficial effects of the present invention are: The present invention includes a first shuttle kiln transportation line, a second shuttle kiln transportation line, at least two calcination devices, and a shuttle kiln picking and placing mechanism. The first shuttle kiln transportation line is used to transport shuttle kilns, and the second shuttle kiln transportation line is used to transport shuttle kilns. Each of the calcination devices is docked with the first shuttle kiln transportation line and the second shuttle kiln transportation line, and is used to calcine the shuttle kilns transported by the first shuttle kiln transportation line or the second shuttle kiln transportation line and send them to the first shuttle kiln transportation line or the second shuttle kiln transportation line. The shuttle kiln picking and placing mechanism straddles the first shuttle kiln transportation line and the second shuttle kiln transportation line, and is used to place the shuttle kilns to be calcined on the first shuttle kiln transportation line or the second shuttle kiln transportation line, and take out the shuttle kilns that have completed calcination on the first shuttle kiln transportation line or the second shuttle kiln transportation line. In the present invention, both ends of the calcination device can be fed and discharged, both the first shuttle kiln transportation line and the second shuttle kiln transportation line can transport shuttle kilns in both directions, and each of the calcination devices can calcine shuttle kilns. Therefore, the entire ternary sulfidation roasting system can form multiple operation modes to meet multiple production requirements.

[0049] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
