[0034] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention. The serial numbers assigned to the components in this text, for example: first, second, etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And as used in this application, terms such as connection and coupling, unless otherwise specified, all include direct and indirect connection (coupling).

[0035] A solid phosgene rapid automatic crystallization device convenient for material taking, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 , Figure 10 , Figure 13 and Figure 14 shown, includes a base 1, a tank body 11, a feed pipe 12, a mounting member 13, a cooler 14, a rotating mechanism 2, a tilting mechanism 5 and a discharging mechanism 7. The top of the base 1 is connected with the tank body 11. The upper left side of the tank body 11 is connected with the feed pipe 12. The upper left side of the tank body 11 is bolted with the mounting member 13. The rear side of the inner wall of the tank body 11 is bolted with the cooler 14. The top of the base 1 is provided with the rotating mechanism 2. The rotating mechanism 2 is located inside the tank body 11. The top of the base 1 is provided with the tilting mechanism 5. The right side of the tank body 11 is provided with the discharging mechanism 7.

[0036] As Figure 2 and Figure 4As shown, the rotating mechanism 2 includes a support column 20, a support frame 21, a cooling disk 22, a gear reduction box 23, a motor 24, and a mounting bracket 25. The top of the base 1 is rotatably connected to the support column 20. The support column 20 is located inside the tank body 11. The support frame 21 is welded to the support column 20. The cooling disk 22 is rotatably connected to the support frame 21 at intervals. The cooler 14 can cool the cooling disk 22, and then transfer the liquid trichloromethyl carbonate to the cooling disk 22 for cooling and crystallization. The mounting bracket 13 is connected to the mounting bracket 25. The gear reduction box 23 and the motor 24 are bolted to the mounting bracket 25. The output shaft of the gear reduction box 23 is connected to the support column 20, and the output shaft of the motor 24 is connected to the input shaft of the gear reduction box 23.

[0037] As Figure 2 , Figure 9 and Figure 10 shown, the tilting mechanism 5 includes a guide rail 50, a contact member 51, a limiting rod 52, and a guiding member 53. The guide rail 50 is connected to the top of the base 1. The height of the right side of the guide rail 50 is higher than that of the left side of the guide rail 50. The right side of the guide rail 50 is a convex portion. The guiding members 53 are connected to the bottom of the cooling disk 22. The limiting rods 52 are movably connected to the guiding members 53. The contact members 51 are connected to the limiting rods 52. The lower ends of the contact members 51 rotate within the guide rail 50. When the contact members 51 rotate to the convex portion of the guide rail 50, they can push the cooling disk 22 to rotate upward to pour out the solid phosgene.

[0038] As Figure 1 , Figure 2 , Figure 13 and Figure 14 shown, the discharging mechanism 7 includes a collection box 70, a discharging box 71, and a vibration generator 72. The collection box 70 is connected to the lower right side of the tank body 11. The discharging box 71 is connected to the bottom of the collection box 70 and is in communication with it. The vibration generator 72 is bolted to the collection box 70.

[0039] First, the cooler 14 cools down the cooling plate 22 below it. Then, under the action of the gear reducer 23, the support column 20 is intermittently rotated by the motor 24, driving the support frame 21 and the cooling plate 22 to rotate intermittently, so that the cooled cooling plate 22 rotates to the lower right of the right end of the feed pipe 12, and the next cooling plate 22 can rotate below the cooler 14 for cooling. At the same time, the cooling plate 22 drives the guide member 53, the limiting rod 52, and the contact member 51 to rotate, causing the contact member 51 to rotate within the guide rail 50. At this time, the feed pipe 12 can be externally connected to liquid trichloromethyl carbonate, and the liquid trichloromethyl carbonate can be transported through the feed pipe 12 to the cooled cooling plate 22. The liquid trichloromethyl carbonate is cooled by the cooling plate 22 to produce solid phosgene. This process is repeated. When the contact member 51 rotates to contact the convex part of the guide rail 50, the guide rail 50 will squeeze the contact member 51 to move upward, driving the limiting rod 52 to move upward. The limiting rod 52 pushes the guide member 53 and the cooling plate 22 to rotate upward, and the cooling plate 22 can pour the solid phosgene into the collection box 70. The vibration generator 72 drives the collection box 70 to vibrate, so that the solid phosgene in the collection box 70 can fall downward through the discharge frame 71 and then be collected manually. When the contact member 51 rotates away from the convex part of the guide rail 50, the guide rail 50 will squeeze the contact member 51 to move downward and reset, driving the limiting rod 52 to move downward and reset. The limiting rod 52 pulls the guide member 53 and the cooling plate 22 to move downward and reset. In this way, the collection work of solid phosgene can be automatically completed, and the operation is simple and convenient.

[0040] Such as Figure 2 , Figure 5 and Figure 6As shown, it further includes a separating mechanism 3. The separating mechanism 3 includes a driving component, a fixed cylinder 31, a knocking member 32, and a spring 33. Fixed cylinders 31 are welded to the bottom of the cooling plates 22. Knocking members 32 are slidably connected to the fixed cylinders 31. The knocking members 32 are in contact with the bottom of the adjacent cooling plates 22. The up and down movement of the knocking members 32 can knock the cooling plates 22 to separate the solid phosgene from the cooling plates 22, preventing the solid phosgene from sticking to the cooling plates 22. A spring 33 is connected between the knocking member 32 and the fixed cylinder 31. A driving component for driving the knocking member 32 to knock the cooling plate 22 is provided on the base 1. The driving component includes a toggling member 30 and a lever 34. The toggling member 30 is welded to the front side of the top of the base 1. Levers 34 are connected to the lower parts of the knocking members 32. The rotation of the lever 34 will contact the toggling member 30. When the cooling plate 22 is rotating, it will drive the fixed cylinder 31, the knocking member 32, and the lever 34 to rotate. When the lever 34 contacts the toggling member 30, the toggling member 30 will squeeze the lever 34 to move downward, driving the knocking member 32 to move downward and separate from the cooling plate 22, and the spring 33 is compressed. When the lever 34 separates from the toggling member 30, the spring 33 returns to its original state, driving the knocking member 32 and the lever 34 to move upward and reset. The knocking member 32 will knock the cooling plate 22 to make the cooling plate 22 vibrate, preventing the solid phosgene from sticking to the cooling plate 22.

[0041] As Figure 2 , Figure 7 and Figure 8 shown, it further includes a liquid discharging mechanism 4. The liquid discharging mechanism 4 includes a transmission component 40, a fixed frame 41, a reciprocating lead screw 42, a connecting member 43, a piston 44, a liquid storage tank 45, and a one-way valve 46. A fixed frame 41 is connected to the mounting frame 25. The reciprocating lead screw 42 is rotatably connected to the fixed frame 41. The reciprocating lead screw 42 is driven by the output shaft of the motor 24 through the transmission component 40. A connecting member 43 is slidably connected to the fixed frame 41. The connecting member 43 is threadedly connected to the reciprocating lead screw 42. A liquid storage tank 45 is bolted to the mounting member 13. The lower left side of the liquid storage tank 45 is communicated with the right end of the feed pipe 12. A piston 44 is slidably connected to the liquid storage tank 45. The piston 44 is fixedly connected to the connecting member 43. The up and down movement of the piston 44 can intermittently discharge the liquid trichloromethyl carbonate. A one-way valve 46 is connected to the bottom of the liquid storage tank 45. Under the action of the transmission component 40, the motor 24 can be controlled to drive the reciprocating lead screw 42 to rotate intermittently. The reciprocating lead screw 42 can drive the connecting member 43 to move up and down reciprocally. The connecting member 43 drives the piston 44 to move up and down reciprocally. When the piston 44 moves upward, the liquid trichloromethyl carbonate can be pumped into the liquid storage tank 45 through the feed pipe 12. When the piston 44 moves downward, the liquid trichloromethyl carbonate can be transmitted to the cooled cooling plate 22 through the one-way valve 46. In this way, the liquid trichloromethyl carbonate can be intermittently fed, preventing the liquid trichloromethyl carbonate from dripping onto the top of the base 1.

[0042] As Figure 2 , Figure 11 and Figure 12 shown, it further includes an atomizing mechanism 6. The atomizing mechanism 6 includes a connecting pipe 60, a connecting frame 61 and an atomizing plate 62. The bottom of the one-way valve 46 is connected to the connecting pipe 60. The lower end of the connecting pipe 60 is connected to the connecting frame 61. An atomizing plate 62 for atomizing liquid trichloromethyl carbonate is connected in the connecting frame 61. When the liquid trichloromethyl carbonate is discharged through the one-way valve 46, it can be transmitted to the connecting frame 61 through the connecting pipe 60. Then the atomizing plate 62 can atomize and spray the liquid trichloromethyl carbonate, so that the atomized trichloromethyl carbonate can be sprayed on the cooled cooling plate 22, increasing the contact area between the trichloromethyl carbonate and the cooled cooling plate 22 and improving the crystallization efficiency of solid phosgene.
