[0002] In the production process of cadmium zinc telluride purification of tellurium, purification by distillation is a common method. Distillation is a physical process of separating mixtures by utilizing the characteristics that substances have different vapor pressures at different temperatures. Before distillation, the preheating process is a common step. Preheating can reduce the time to reach the required distillation temperature and improve the efficiency of the distillation process. In the prior art, there is only a single air duct for preheating the tellurium material blank, and the heating direction is not uniform enough, so that the outer surface and the inside of the tellurium material blank cannot be fully heated, affecting the subsequent distillation effect.

[0003] In summary, in order to solve the deficiencies in the prior art, it is necessary to design a distillation preheating device for cadmium zinc telluride purification of tellurium with a simple structure and convenient use. Summary of the Utility Model

[0017] The following combines the embodiments and the attached Figures 1 to 4 , and further elaborates on the technical solutions of the present utility model.

[0018] Embodiment 1

[0019] A distillation preheating device for purifying tellurium from cadmium telluride includes: a box body 2 and a heating device 4. The box body 2 includes a front side plate 21, a rear side plate 22, a bottom plate 23, and a top plate 24. The front side plate 21 is provided with a feed inlet 211, the rear side plate 22 is provided with a discharge outlet 221, and the bottom plate 23 is provided with an S-shaped track groove 231 communicating the feed inlet 211 and the discharge outlet 221. Inside the box body 2, there are a partition plate one 11 and a partition plate two 12. The partition plate one 11 and the partition plate two 12 divide the inside of the box body 2 into a cavity one 51, a cavity two 52, and a cavity three 53. The heating device 4 includes a hot chamber 41, a burner 42, a blower 43, and an air outlet pipe 44. The burner 42 communicates with the inside of the hot chamber 41. The blower 43 is fixed on the hot chamber 41 and sends the hot air inside the hot chamber 41 to the air outlet pipe 44. The air outlet pipe 44 includes a main pipe 441, a branch pipe one 442 communicating with the main pipe 441, and a branch pipe two 443. The branch pipe one 442 communicates with the right end of the cavity one 51, the branch pipe two 443 communicates with the left end of the cavity two 52, and a branch pipe three 444 is connected to the branch pipe two 443. The branch pipe three 444 communicates with the upper end of the cavity three 53. Inside the feed inlet 211, there is a first baffle plate 212 rotatably connected, and outside the discharge outlet 221, there is a second baffle plate 222 rotatably connected.

[0020] As a further preferred embodiment, both the first baffle plate 212 and the second baffle plate 222 include a fixed block 31, a rotating shaft 32, and a rotating plate 33. The fixed block 31 is fixed on the front side plate 21 and the rear side plate 22. The rotating shaft 32 is rotatably connected to the fixed block 31, and the rotating plate 33 is sleeved on the end of the rotating shaft 32.

[0021] As a further preferred embodiment, a branch pipe 445 is provided on the branch pipe three 444, and the branch pipe 445 is located directly above the S-shaped track groove 231.

[0022] As Figures 1 to 4 shown, the working principle of the present utility model: when the tellurium material blank is fed into the box body 2, the tellurium material blank pushes the first baffle 212 inside the feed port 211 until the tellurium material blank completely enters, and then the first baffle 212 rotates inward under its own weight to block the feed port 211. After the tellurium material blank is preheated, it pushes the second baffle 222 until the tellurium material blank is completely sent out, and then the second baffle 222 rotates inward under its own weight to block the discharge port 221, which can reduce the escape of heat from the feed port 211 and the discharge port 221 and improve the preheating effect.

[0023] Feed the tellurium material blank to be preheated into the interior from the feed port 211 of the box body 2, move the tellurium material blank along the S-shaped track groove 231 and then send it out from the discharge port 221. The burner 42 at the upper end heats the air and then sends the hot air in the hot chamber to the air outlet pipe 44 through the blower 43. The air outlet pipe 44 includes multiple branched pipelines. First, the vertical hot air preheating inside the tellurium material blank is realized through the branch pipe three 444 connected to the upper end of the chamber three 53, then the hot air preheating of the right end face of the tellurium material blank is realized through the branch pipe two 443 connected to the upper end of the chamber two 52, and finally the hot air preheating of the left end face of the tellurium material blank is realized through the branch pipe one 442 connected to the upper end of the chamber one 51, which further improves the full heating of the overall outer surface and the interior of the tellurium material blank and ensures the subsequent distillation effect.

[0024] The partition board one 11 and the partition board two 12 divide the interior of the box body 2 into the chamber one 51, the chamber two 52 and the chamber three 53, and single and differently directed hot air preheating is realized in different chambers. The setting of the partition board can prevent the hot air in each chamber from convecting and thus affect the actual hot air effect.

[0025] And the setting of the S-shaped track groove 231 enables the same tellurium material blank to be subjected to multiple vertical hot air preheatings, hot air preheatings of the right end face and hot air preheatings of the left end face, which further improves the preheating efficiency.

[0026] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present application based on the concept of the present utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
