Specific implementation mode

[0019] The following will specifically describe the preferred embodiments of the present invention in conjunction with the accompanying drawings. 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] As Figures 1-5 shown, the embodiment of the present invention provides a sagger rotary calcination treatment line, which includes: the first conveying line 1 of the sagger, the second conveying line 2 of the sagger, and at least two calcination devices 3. The first conveying line 1 of the sagger conveys the sagger along the first direction, the second conveying line 2 of the sagger conveys the sagger along the second direction, and each calcination device 3 is docked with the first conveying line 1 of the sagger and the second conveying line 2 of the sagger, and is used for calcining the sagger conveyed by the first conveying line 1 of the sagger or the second conveying line 2 of the sagger, and sending it to the first conveying line 1 of the sagger or the second conveying line 2 of the sagger.

[0021] In the present invention, at least two calcination devices 3 are provided, and each calcination device 3 can calcine the sagger. When any one of the calcination devices 3 needs to be repaired, the other calcination devices 3 can maintain the normal operation of the entire calcination treatment line and avoid affecting the production progress.

[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 crucibles on the first crucible transportation line 1 and the second crucible transportation line 2.

[0023] Specifically, the first crucible transportation line 1 includes a first transportation track 11, a first slider 12, and a first crucible carrier plate 13. The first transportation track 11 is arranged along a first direction. The first slider 12 is arranged on the first transportation track 11 and can actively slide along the first transportation track 11 and stop at any position in its moving stroke. The first crucible carrier plate 13 is fixed on the first slider 12 and is used for carrying crucibles.

[0024] Furthermore, when the first slider 12 moves along the first transportation track 11, it has a first loading / unloading position where the first crucible carrier plate 13 is in the loading / unloading area, and first docking positions where the first crucible carrier 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] Furthermore, a first pushing component 14 is arranged on the first crucible carrier plate 13. The first pushing component 14 has a pushing end for pushing the crucible, and is used for pushing 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] Furthermore, a first groove 131 for accommodating the first pushing component 14 is formed on the first crucible carrier plate 13. The first pushing component 14 includes a first pushing sliding rod 141, a first pushing slider 142, a first pushing cylinder 143, and a first pushing plate 144. The first pushing sliding rod 141 is embedded in the first groove 131. The first pushing slider 142 is slidably connected with the first pushing sliding rod 141. The first pushing cylinder 143 is fixed on the first pushing slider 142. The first pushing plate 144 is fixed on the movable end of the first pushing cylinder 143. The movable end of the first pushing cylinder 143 expands and contracts to drive the first pushing 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 pushing component 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, thereby realizing the movement of the crucible.

[0028] Specifically, the second transport line 2 of the sagger includes a second transport track 21, a second slider 22, and a second sagger carrier plate 23. The second transport track 21 is arranged along a first direction. The second slider 22 is arranged on the second transport track 21 and can actively slide along the second transport track 21 and stop at any position in its moving stroke. The second sagger carrier plate 23 is fixed to the second slider 22 and is used for carrying the sagger.

[0029] Furthermore, when the second slider 22 moves along the second transport track 21, it has a second pick-and-place position where the second sagger carrier plate 23 is in the pick-and-place area and a second docking position where the second sagger carrier plate 23 is docked with the calcination device 3; the second slider 22 can switch between the second pick-and-place position and the second docking position.

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

[0031] Furthermore, a second groove 231 for accommodating the second pusher assembly 24 is formed on the second sagger 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 to the second pusher slider 242. The second pusher plate 244 is fixed to the movable end of the second pusher cylinder 243. The movable end of the second pusher cylinder 243 expands and contracts 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 realize pushing the sagger from the second sagger carrier plate 23 to the calcination device 3, and can also realize pushing the sagger from the calcination device 3 to the second sagger carrier plate 23, so as to realize the movement of the sagger.

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

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

[0035] Further, 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 crucibles into or out of the calcination furnace 32 from both ends.

[0036] Further, a sliding rod is provided at the bottom of the sliding trough body 311. The calcination pusher 312 includes a calcination pusher slider 312a, a calcination pusher cylinder 312b, and a calcination push 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 push 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 push plate 312c to retract into the sliding trough body 311 or protrude relative to the sliding trough body 311.

[0037] Further, the calcination furnace 32 includes a furnace body 321 and a number of heating components. The furnace body 321 straddles the sliding trough 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 trough body 311. The heating components are arranged on the inner wall of the furnace body 321. When the crucible enters the furnace body 321, the inside of the furnace body 321 is heated, thereby calcining the crucible.

[0038] In this embodiment, a number of loading and unloading devices 4 are further included. In some feasible embodiments, the loading and unloading devices 4 are arranged at the ends of the first crucible transportation line 1 and the second crucible transportation line 2 and are used to load and unload the crucibles on the first crucible transportation line 1 and the second crucible transportation line 2.

[0039] In some other feasible embodiments, the pick-and-place device 4 is arranged on one side of the corresponding positions of the first shuttle transportation line 1 and the second shuttle transportation line 2 of the shuttle and the calcination device 3.

[0040] The pick-and-place device 4 includes a manipulator. The clamping end of the manipulator can pick up a shuttle from the outside and place it on the first shuttle transportation line 1 or the second shuttle transportation line 2, and can also pick up the shuttle on the first shuttle transportation line 1 or the second shuttle transportation line 2 and place it outside. The manipulator is a conventional device in the prior art, and those skilled in the art have sufficient understanding of it, so the specific structural content will not be elaborated here.

[0041] Thus, multiple calcination methods can be realized: 1. The pick-and-place device 4 is arranged at the ends of the first shuttle transportation line 1 and the second shuttle transportation line 2. The shuttle is placed on the first shuttle transportation line 1 at the end of the first shuttle transportation line 1. The first shuttle transportation line 1 sends the uncalcined shuttle into the calcination transportation component 31 and then into the calcination furnace 32 for calcination. The calcined shuttle is sent by the calcination transportation component 31 to the second shuttle transportation line 2 and taken away from the end of the second shuttle transportation line 2; or the uncalcined shuttle is placed at the end of the second shuttle transportation line 2. The second shuttle transportation line 2 sends the uncalcined shuttle into the calcination transportation component 31 and then into the calcination furnace 32 for calcination. The calcined shuttle is sent by the calcination transportation component 31 to the first shuttle transportation line 1 and taken away from the end of the first shuttle transportation line 1; thus, a one-way circulation line of the first shuttle transportation line 1, the calcination device 3, and the second shuttle transportation line 2 is formed. 2. The pick-and-place device 4 is arranged at the ends of the first shuttle transportation line 1 and the second shuttle transportation line 2. The uncalcined shuttle is sent from the first shuttle transportation line 1 and the second shuttle transportation line 2 into the calcination transportation component 31 and then into the calcination furnace 32 for calcination. The calcined shuttle is sent by the calcination transportation component 31 to the first shuttle transportation line 1 and the second shuttle transportation line 2, and multiple calcination furnaces 32 work alternately; thus, feeding and discharging are carried out simultaneously on two conveying lines. Compared with the single-line single-furnace circulation calcination method in the prior art, the calcination material capacity per unit time is increased significantly, the heat energy utilization efficiency of the calcination furnace is higher, and the production efficiency is improved. 3. The loading and unloading device 4 is arranged on one side of the corresponding positions of the first refractory container transportation line 1 and the second refractory container transportation line 2 and the calcination device 3. The refractory container is placed on the first refractory container transportation line 1, and the first refractory container transportation line 1 sends the uncalcined refractory container into the calcination transportation component 31 and then into the calcination furnace 32 for calcination. The calcined refractory container is sent by the calcination transportation component 31 to the second refractory container transportation line 2. The corresponding loading and unloading device 4 takes away the calcined refractory container and places the uncalcined refractory container. The uncalcined refractory container is then transported by the second refractory container transportation line 2 to the position of another calcination device 3, and the uncalcined refractory container is sent into the calcination transportation component 31 and then into the calcination furnace 32 for calcination. The calcined refractory container is sent by the calcination transportation component 31 to the first refractory container transportation line 1. Thus, the transportation time and the waiting time of the calcination device 3 can be significantly shortened, heat waste in the calcination device 3 can be avoided, and the utilization efficiency of thermal energy and the production efficiency can be improved.

[0042] The beneficial effects of the present invention are as follows: The present invention includes a first refractory container transportation line, a second refractory container transportation line, and at least two calcination devices. The first refractory container transportation line transports the refractory containers in a first direction, and the second refractory container transportation line transports the refractory containers in a second direction. Each calcination device is docked with the first refractory container transportation line and the second refractory container transportation line, and is used to calcine the refractory containers transported by the first refractory container transportation line or the second refractory container transportation line and send them to the first refractory container transportation line or the second refractory container transportation line. In the present invention, at least two calcination devices are provided, and each calcination device can calcine the refractory containers. When any one of the calcination devices needs to be repaired, the other calcination devices can maintain the normal operation of the entire calcination processing line and avoid affecting the production progress.

[0043] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of 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.
