[0028] Please see Figure 1 , Figure 2 , Figure 1 This is a schematic diagram of the structure of a chemical raw material intermediate preparation and purification device according to an embodiment of the present invention. The chemical raw material intermediate preparation and purification device includes: a water bath tank 1, a material tank 2, a heating component 3, and a collection component 4. The interior of the water bath tank 1 is hollow. The material tank 2 is built into the water bath tank 1. The heating component 3 is built into the water bath tank 1. The collection component 4 includes a collection tank 41, a guide pipe 42, and a filter element 43. The collection tank 41 is placed outside the water bath tank 1 and connected to the water bath tank 1. One end of the guide pipe 42 is connected to the interior of the material tank 2, and the other end is connected to the interior of the collection tank 41. The filter element 43 is built into the guide pipe 42 and connected to the guide pipe 42.

[0029] In this device, a material tank 2 is provided inside the water bath tank 1 for placing the material to be purified. The heating component 3 is built into the water bath tank 1 and can heat the material by means of a water bath. The inside of the collection tank 41 is connected to the inside of the material tank 2 through the guide pipe 42, and the inside of the guide pipe 42 is connected to the filter element 43.

[0030] Compared with the prior art, by setting a filter element 43 on the guide pipe, the filter element 43 can filter and separate the water vapor in the intermediate, preventing the water vapor from entering the collection tank 41 along with the intermediate along the guide pipe 42. This solves the technical problem in the prior art where the water vapor generated in the container enters the collection frame along with the intermediate, thus reducing the purity of the intermediate.

[0031] Furthermore, the water bath tank 1 in this device is a sealed reaction vessel structure that is common and easy to purchase on the market, and the top of the material tank 2 is provided with an inverted funnel-shaped guide bucket, which is conducive to the gaseous intermediate entering the collection tank 41 along the guide pipe 42. The water bath tank 1 and the material tank 2 are conventional settings known to those skilled in the art, and will not be described in detail here.

[0032] In this embodiment, as Figure 1 , Figure 2As shown, the guide pipe 42 includes a first pipe body 421 and a second pipe body 422. One end of the first pipe body 421 is connected to the inside of the material tank 2, and one end of the second pipe body 422 is connected to the inside of the collection tank 41, while the other end is detachably connected to the other end of the first pipe body 421.

[0033] The guide pipe 42 is a two-section detachable structure, which can be connected to the interior of the material tank 2 and the collection tank 41 respectively.

[0034] In one embodiment, such as Figure 2 As shown, the other end of the first tube 421 is provided with a first external thread, the other end of the second tube 422 is provided with a second external thread, and the filter element 43 includes a connecting sleeve 431. Both ends of the connecting sleeve 431 are respectively provided with internal threads, and both ends of the connecting sleeve 431 are respectively threaded to the first external thread or the second external thread.

[0035] The guide tube 42 is detachably connected to the first tube body 421, the second tube body 422 and the connecting sleeve 431 by means of threaded connection, which is simple in structure and easy to operate.

[0036] In one embodiment, such as Figure 2 As shown, the filter element 43 also includes filter cotton 432, which is circular and embedded in the connecting sleeve 431. Both ends of the filter cotton 432 abut against the other end of the first tube 421 and the other end of the second tube 422, respectively.

[0037] By providing a filter cotton 432 inside the connecting sleeve 431, water vapor contained in the gaseous intermediate can be filtered. The filter cotton 432 is a common and readily available part on the market and is a conventional setting known to those skilled in the art, so it will not be described in detail here.

[0038] Furthermore, both ends of the filter cotton 432 are respectively connected to the other ends of the first tube 421 and the second tube 422, which can ensure the stability of the filter cotton 432 installation and improve the filtration efficiency.

[0039] In one embodiment, such as Figure 2 As shown, the connecting sleeve 431 has an annular groove on its circumferential inner wall. The annular groove is connected to the interior of the connecting sleeve 431, and the filter cotton 432 is stuck in the annular groove.

[0040] The filter cotton 432 is engaged with the annular groove, which can improve the stability of the filter cotton 432 installation and improve the filtration efficiency.

[0041] In one embodiment, such as Figure 2As shown, the filter element 43 also includes two sealing rings 433, which are respectively disposed at both ends of the filter cotton 432, and both ends of the sealing rings 433 abut against the filter cotton 432 and the other end of the first tube 421 or the other end of the second tube 422.

[0042] The sealing rings 433 are respectively disposed between the filter cotton 432 and the other end of the first tube 421 or the other end of the second tube 422, and respectively abut against the other end of the filter cotton 432 and the other end of the first tube 421 or the other end of the second tube 422, which can improve the sealing of the connection and prevent leakage of the intermediate body.

[0043] Furthermore, the sealing ring 433 here is a common and readily available part on the market, and is a conventional setting known to those skilled in the art, so it will not be described in detail here.

[0044] In one embodiment, such as Figure 1 As shown, the second tube 422 is in the shape of an inverted "U", and one end of the second tube 422 is built into the collection tank 41 and connected to the collection tank 41.

[0045] The second tube 422, which is inverted "U" shape, is connected at one end to the inside of the collection tank 41 and at the other end to the first tube 421, so that the gaseous intermediate can be formed into a liquid at one end of the second tube 422 and flow into the collection tank 41.

[0046] In one embodiment, such as Figure 1 As shown, the collection component 4 also includes a cooling component 44, which includes a cooling coil 441. The cooling coil 441 is wrapped around the outer wall of one end of the second tube body 422 for heat exchange with one end of the second tube body 422.

[0047] The cooling coil 441 is wrapped around the outer wall of one end of the second tube 422, which can accelerate the liquefaction of the intermediate.

[0048] In one embodiment, such as Figure 1 As shown, the cooling component 44 also includes a circulating water tank 442, an inlet pipe 443, an outlet pipe 444, and a water pump 445. The circulating water tank 442 is connected to the water bath tank 1. One end of the inlet pipe 443 is connected to the interior of the circulating water tank 442, and the other end is connected to the cooling coil 441. One end of the outlet pipe 444 is connected to the interior of the circulating water tank 442, and the other end is connected to the cooling coil 441. The water pump 445 is connected to the circulating water tank 442, and the inlet end of the water pump 445 is connected to the interior of the circulating water tank 442, and the outlet end is connected to one end of the inlet pipe 443.

[0049] The circulating water tank 442, the inlet pipe 443, the outlet pipe 444, and the water pump 445 are used to realize the circulation of coolant in the cooling coil 441.

[0050] Furthermore, the circulating water tank 442, inlet pipe 443, outlet pipe 444, and water pump 445 are all common and readily available equipment on the market, and will not be described in detail here.

[0051] In one embodiment, such as Figure 1 As shown, the collection component 4 also includes an insulation sleeve 45, which is fitted onto the outer wall of the guide tube 42 and the connecting sleeve 431.

[0052] By installing an insulation sleeve 45 on the outer wall of the guide tube 42 and the connecting sleeve 431, the liquefaction of the intermediate on the first tube 421 or the connecting sleeve 431 can be reduced, thereby improving the purification efficiency.

[0053] Furthermore, the insulation jacket 45 here is a common and readily available piece of equipment on the market, so it will not be described in detail here.

[0054] To better understand this utility model, the following is combined with... Figures 1 to 2 The technical solution of this utility model is described in detail below:

[0055] The water bath tank 1 is equipped with a material tank 2 for holding the material to be purified. The heating component 3 is built into the water bath tank 1 and can heat the material by water bath. The inside of the collection tank 41 is connected to the inside of the material tank 2 through the guide pipe 42. At the same time, the inside of the guide pipe 42 is connected to the filter element 43. Compared with the prior art, by setting the filter element 43 on the guide pipe, the water vapor in the intermediate can be filtered and separated, preventing the water vapor from entering the collection tank 41 along with the intermediate along the guide pipe 42. This can solve the technical problem in the prior art where the water vapor generated in the container enters the collection box along with the intermediate, thus reducing the purity of the intermediate.

[0056] In the specific working process of this utility model, the heating component 3 heats the water in the water bath tank 1, causing the material in the material tank 2 to be gradually vaporized. The gaseous intermediate enters the collection tank 41 through the guide pipe 42, the connecting sleeve 431, and the filter cotton 432. The water vapor is filtered out by the filter cotton 432 and cannot continue to enter the second tube 422 and the collection tank 41. The cooling coil 441 can continuously exchange heat with one end of the second tube 422, causing the gaseous intermediate to condense at one end of the second tube 422 and form a liquid intermediate, which is collected by the collection tank 41.

[0057] This device, through the aforementioned structure, can solve the technical problem in the prior art where water vapor generated inside the container enters the collection frame along with the intermediate, thereby reducing the purity of the intermediate.

[0058] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
