Description

Technical Field

[0001] The utility model belongs to the technical field of trimethylsilylamine production, and particularly relates to a trimethylsilylamine production device. Background Technique

[0002] Trimethylsilylamine is an organic compound. It is an important reagent for organic synthesis and organometallic chemical reactions and has specific chemical properties and uses. Trimethylsilylamine can be converted into other useful compounds through different chemical reactions. For example, it can react with phosphorus pentachloride in hexane at 0 °C to form monomeric trichloro(trimethylsilyl)phosphazene, which can be further polymerized into poly(dichlorophosphazene). This polymer has a definite molecular weight and dispersity. In addition, trimethylsilylamine can also react with fluorine gas in acetonitrile at -40 °C to form nitrogen trifluoride, which is an important gas used for plasma etching of silicon chips. Therefore, trimethylsilylamine has an important position and wide application in the chemical industry.

[0003] During the production of trimethylsilylamine, stirring operations need to be performed on a variety of reaction solvents. However, the existing stirring equipment has poor use effects, resulting in insufficient mixing of various reaction solvents. As a result, workers need to remix various reaction solvents, which easily reduces the production efficiency of trimethylsilylamine and cannot meet the usage requirements.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a trimethylsilylamine production device.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present utility model and should not be regarded as an admission or any form of implication that this information constitutes prior art already known to those of ordinary skill in the art.

Detailed implementation manners

[0035] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] As Figures 1 to 6 shown, a trimethylsilylamine production device in an embodiment of the present utility model includes a stirring tank 1 and an auxiliary stirring mechanism 2.

[0037] Among them, an upper cover 101 is connected to the stirring tank 1. Through the mutual cooperation of the upper cover 101, the stirring tank 1 is used to accommodate a variety of reaction solvents so as to mix the various reaction solvents, and then for the production of trimethylsilylamine.

[0038] In addition, a stirring motor 102 is installed on the upper cover 101. The output end of the stirring motor 102 is connected to a stirring shaft 103. The stirring shaft 103 is arranged inside the stirring tank 1. When the stirring motor 102 operates, the stirring motor 102 can drive the stirring shaft 103 to rotate.

[0039] Specifically, an air duct 1031 is provided inside the stirring shaft 103, and a plurality of connecting holes 1032 are provided on the side wall of the stirring shaft 103. The air duct 1031 is communicated with the inside of the stirring tank 1 through the connecting holes 1032. Both the air duct 1031 and the connecting holes 1032 are used for the flow of gas, that is, the gas in the hollow sleeve 203 enters the air duct 1031 through the connecting holes 1032 for flow.

[0040] In addition, a number of stirring rods 104 are connected to the side wall of the stirring shaft 103. When the stirring shaft 103 rotates, the stirring rods 104 can also rotate synchronously with the stirring shaft 103, thereby preliminarily mixing a variety of reaction solvents in the stirring tank 1.

[0041] As Figures 1 to 6 shown, the auxiliary stirring mechanism 2 is installed on the upper cover 101. The auxiliary stirring mechanism 2 is used to further mix a variety of reaction solvents in the stirring tank 1 by cooperating with the stirring rods 104, so as to improve the mixing effect of the various reaction solvents, enabling the staff to avoid repeatedly remixing the reaction solvents, and thus improving the production efficiency of trimethylsilylamine.

[0042] Among them, the auxiliary stirring mechanism 2 includes an air pump 201. An air delivery pipe 202 is connected to the air pump 201. When the air pump 201 operates, it extracts external air and transports it through the air delivery pipe 202.

[0043] In addition, one end of the air delivery pipe 202 is connected to an air injection mechanism. The air injection mechanism is connected to the stirring shaft 103. By the mutual cooperation of the air injection mechanism and the stirring rods 104, a variety of reaction solvents can be further mixed to improve the mixing effect of the various reaction solvents.

[0044] Specifically, the air injection mechanism includes a hollow sleeve 203. The hollow sleeve 203 is rotatably connected to the stirring shaft 103 and is arranged outside the connection hole 1032. The hollow sleeve 203 is used to transport the gas delivered by the air delivery pipe 202 into the air duct 1031 so that the gas can flow through the air duct 1031.

[0045] In addition, a number of fixing rods 204 are connected between the top wall of the hollow sleeve 203 and the upper cover 101 to fix the hollow sleeve 203, making it not easy for the hollow sleeve 203 to rotate with the stirring shaft 103.

[0046] Preferably, an anti-corrosion layer is provided on the outer side of the fixing rods 204 to improve the service life of the fixing rods 204.

[0047] As Figures 1 to 6 shown, one end of the stirring shaft 103 away from the hollow sleeve 203 is connected to a base 205. The base 205 is used to install a hollow tube 206. A hollow tube 206 is fixedly connected to the base 205, and a number of through holes are provided through the hollow tube 206. The gas in the hollow tube 206 can be discharged into the stirring tank 1 through the through holes, and the gas can be used to remix the various reaction solvents in the stirring tank 1 to ensure the mixing effect of the solvents.

[0048] Among them, a connecting pipe 207 is connected between the hollow tube 206 and the air duct 1031. The gas in the air duct 1031 enters the hollow tube 206 through the connecting pipe 207.

[0049] In addition, a one-way valve 208 is installed on the connecting pipe 207, so that the gas in the air duct 1031 can only enter the hollow pipe 206 unidirectionally, and the solvent in the stirring tank 1 will not enter the air duct 1031 through the connecting pipe 207.

[0050] Preferably, the gas delivery pipe 202 is made of a heat-conducting metal material, and a heating wire 209 is wound around the outside of the gas delivery pipe 202. If it is necessary to heat the solvent in the stirring tank 1, the heating wire 209 can be made to generate heat. The heating wire 209 can instantaneously heat the gas flowing in the gas delivery pipe 202, and then be used to increase the temperature of the gas entering the stirring tank 1, so that the solvent can be better mixed.

[0051] Specifically, a protective sleeve is provided outside the heating wire 209 to protect the heating wire 209.

[0052] In addition, an air outlet pipe is provided on the upper cover 101 to discharge the gas in the stirring tank 1, so that the gas pressure in the stirring tank 1 is not likely to be too high.

[0053] As Figures 1 to 6 shown, one end of the air outlet pipe located outside the upper cover 101 is connected to a purification box 3, and the gas in the stirring tank 1 will enter the purification box 3 through the air outlet pipe. A wire mesh rack is installed in the purification box 3, and activated carbon is placed on the wire mesh rack. An air outlet net 301 is provided at the top of the purification box 3. After the gas in the purification box 3 is purified by the activated carbon, it is discharged through the air outlet net 301.

[0054] Among them, a replacement door 302 is hingedly connected to the side wall of the purification box 3. The replacement door 302 corresponds to the activated carbon, which is convenient for replacing the activated carbon.

[0055] During specific use, a variety of reaction solvents are added to the stirring tank 1, and the stirring motor 102 is operated. The stirring motor 102 drives the stirring shaft 103 and the stirring rod 104 to rotate. The rotating stirring rod 104 can preliminarily mix the variety of reaction solvents in the stirring tank 1.

[0056] The air pump 201 is operated. The air pump 201 extracts external gas, and the external gas enters the hollow sleeve 203 through the gas delivery pipe 202, and then enters the air duct 1031 through the connection hole 1032 for flow. The gas in the air duct 1031 enters the hollow pipe 206 unidirectionally through the connecting pipe 207, and is sprayed into the reaction solvent in the stirring tank 1 through a plurality of through holes on the side wall of the hollow pipe 206. Since the hollow pipe 206 rotates with the stirring shaft 103, that is, the gas sprayed by the hollow pipe 206 will be in a spiral shape. Therefore, the gas sprayed by the hollow pipe 206 can transport the reaction solvent from the bottom of the stirring tank 1 upward, and combined with the stirring action of the stirring rod 104, the variety of reaction solvents can achieve a better mixing effect.

[0057] The gas in the stirring tank 1 enters the purification box 3 through the gas outlet pipe. After being purified by activated carbon, it is discharged through the gas outlet net 301.
