[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, it is a structural diagram of a metal calcium slag distillation recovery and treatment device provided by an embodiment of the present invention, including a distiller body 1, the distiller body 1 is composed of a distiller body 11 and a top cover 12, a distillation chamber 111 is downwardly opened on the surface of the distiller body 11, a guide tube 121 is fixedly installed on the top cover 12, and the end of the guide tube 121 away from the top cover 12 is connected to an external condenser, a carrying plate 2 is arranged in the distillation chamber 111, and the surface of the carrying plate 2 is provided with evenly distributed distillation mesh holes, a swinging assembly 4 connected to the carrying plate 2 is arranged on the side wall of the distiller body 11, and the swinging assembly 4 is used to control the carrying plate 2 to reciprocate in the distillation chamber 111 to a tilted state, and a flipping mechanism 3 is arranged on the surface of the carrying plate 2, and the flipping mechanism 3 includes a flipping plate 31. A positioning component 32 and a rotating component 33. The positioning component 32 is located on the surface of the supporting plate 2 and is connected to the flipping plate 31. The positioning component 32 is used to support multiple groups of flipping plates 31 above the supporting plate 2. The rotating component 33 is located on the surface of the supporting plate 2 and is connected to the positioning component 32. When the supporting plate 2 is tilted, the rotating component 33 controls the flipping plate 31 to rotate above the supporting plate 2 by cooperating with the positioning component 32. The distillation chamber 111 is provided with a stirring mechanism 5 located below the supporting plate 2. The stirring mechanism 5 includes a stirring rod 51 and a transmission component 52. The transmission component 52 is located on the bottom wall of the supporting plate 2 and is connected to the stirring rod 51. The swinging supporting plate 2 and the transmission component 52 cooperate with each other to control the stirring rod 51 to rotate in the distillation chamber 111.

[0024] When in use, a batch of calcium slag is put into the distillation chamber 111, and the calcium slag falls onto the surface of the supporting plate 2. When the calcium slag is distilled, the swinging component 4 can control the supporting plate 2 to rotate back and forth in the distillation chamber 111 to an inclined state. When the supporting plate 2 swings back and forth, the calcium slag moves back and forth synchronously on the surface of the supporting plate 2. When the calcium slag moves back and forth on the surface of the supporting plate 2, the stacking effect of the calcium slag can be effectively destroyed, so that the calcium slag is fully in contact with the high-temperature steam, and the metallic calcium in the calcium slag is converted into a gaseous state and flows into the condenser through the guide tube 121.

[0026] When in use, the side plates 321 and the rotating columns 322 cooperate with each other to support and position the flipping plates 31, so that multiple groups of flipping plates 31 are stably located above the supporting plate 2. When the supporting plate 2 swings back and forth, the rotating assembly 33 controls the rotating columns 322 to rotate between the two groups of side plates 321. The rotating columns 322 drive the flipping plates 31 to rotate synchronously, and the flipping plates 31 can flip the calcium slag on the surface of the supporting plate 2.

[0027] like Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, as a preferred embodiment of the present invention, the rotating component 33 includes two groups of relatively distributed slide grooves 332 opened on the surface of the supporting plate 2, and a sliding column 333 is slidably installed in the slide groove 332. The two ends of the rotating column 322 respectively extend to the outside of the side plate 321 and are fixedly installed with a fixed toothed disk 331. The surface of the sliding column 333 extends to the outside of the slide groove 332 and is fixedly installed with a first rack 334 that meshes with the fixed toothed disk 331.

[0028] When the supporting plate 2 swings back and forth in the distillation chamber 111, the sliding column 333 moves back and forth synchronously along the slide groove 332 under the action of gravity. When moving, the sliding column 333 drives the first rack 334 to move synchronously. The first rack 334 contacts and meshes with the fixed gear disc 331.

[0032] When the supporting plate 2 swings, it drives the arc bar 523 to move synchronously, and the arc bar 523 drives the second rack 524 to move synchronously. The second rack 524 is meshed with the control gear disc 522 for transmission, which can drive the control gear disc 522 to rotate. The control gear disc 522 cooperates with the rotating rod 521 to drive the stirring rod 51 to rotate around the rotating rod 521. When the stirring rod 51 rotates, the calcium slag under the supporting plate 2 can be fully stirred.

[0035] The working principle of the present invention is: when in use, a batch of calcium slag is put into the distillation chamber 111, and the calcium slag falls onto the surface of the supporting plate 2. When the calcium slag is distilled, the motor 43 drives the transmission disk 46 to rotate, and the transmission disk 46 drives the control column 47 to rotate synchronously. The control column 47 cooperates with the control groove 45 to drive the swing plate 44 to swing back and forth in the control box 41. When the swing plate 44 swings, it drives the rotating rod 42 to swing back and forth synchronously, and the rotating rod 42 drives the supporting plate 2 to swing back and forth synchronously in the distillation chamber 111. When the bearing plate 2 swings back and forth, the calcium slag moves back and forth synchronously on the surface of the bearing plate 2. When the calcium slag moves back and forth on the surface of the bearing plate 2, the stacking effect of the calcium slag can be effectively destroyed, so that the calcium slag is fully in contact with the high-temperature steam, and the metal calcium in the calcium slag is converted into a gaseous state and flows into the condenser through the guide tube 121. When the bearing plate 2 swings back and forth, the sliding column 333 moves back and forth synchronously along the slide groove 332 under the action of gravity. When the sliding column 333 moves, the first rack 334 moves synchronously. The first rack 334 contacts and meshes with the fixed toothed disc 331. The first rack 334 meshes with the fixed toothed disc 331 for transmission, which can drive the fixed toothed disc 331 to rotate, and the fixed toothed disc 331 drives the rotating column 322 to rotate synchronously. The rotating column 322 drives the flipping plate 31 to rotate synchronously, and the flipping plate 31 can flip the calcium slag on the surface of the bearing plate 2. The flipping plate 31 can further flip the calcium slag on the surface of the bearing plate 2, effectively improving the recovery rate of the metal calcium in the calcium slag. While the calcium slag on the surface of the supporting plate 2 is being turned over, the supporting plate 2 drives the arc bar 523 to move synchronously when it swings, and the arc bar 523 drives the second rack 524 to move synchronously, and the second rack 524 engages with the control gear disc 522 for transmission, which can drive the control gear disc 522 to rotate, and the control gear disc 522 cooperates with the rotating rod 521 to drive the stirring rod 51 to rotate around the rotating rod 521, and the stirring rod 51 can fully stir the calcium slag under the supporting plate 2 when it rotates.
