Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum dehydration equipment, and more particularly to a vacuum dehydration device for sodium fatty acylmethyl taurate suitable for high viscosity systems. Background Technology
[0002] Sodium fatty acyl methyl taurate is a type of anionic surfactant. It is relatively stable to acidic and alkaline solutions and hard water. It is generally prepared by the condensation of oleoyl chloride and sodium methyl taurate. Vacuum dehydration equipment can remove residual water or solvents from its synthesis or processing to improve product purity, stability and storage performance.
[0003] Sodium fatty acylmethyl taurate has a high viscosity, which leads to problems such as high heat transfer resistance, easy adhesion to the wall and clumping, and slow moisture diffusion during the drying process. In the process of vacuum dehydration and drying, it has poor fluidity, low heat transfer efficiency and easy clumping. The dehydration and drying of sodium fatty acylmethyl taurate in high viscosity system is quite inconvenient. Utility Model Content
[0004] In view of this, the present invention provides a vacuum dehydration device for sodium fatty acylmethyl taurate suitable for high viscosity systems. The main technical problem to be solved is that sodium fatty acylmethyl taurate has poor fluidity, low heat transfer efficiency and easy agglomeration during vacuum dehydration.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vacuum dehydration device for sodium fatty acylmethyl taurate suitable for high viscosity systems, comprising a shell, an inner liner fixedly connected inside the shell, a motor fixedly connected to the outer surface of the shell, a rotating shaft fixedly connected to the output end of the motor, the end of the rotating shaft away from the motor passing through the shell to the right side of the shell, an inner cavity opened inside the rotating shaft, a sealing plug installed at the right end of the rotating shaft, an air inlet pipe fixedly connected inside the sealing plug, the left end of the air inlet pipe located inside the inner cavity, an air outlet pipe fixedly connected inside the sealing plug, the left end of the air outlet pipe located inside the inner cavity, the length of the air outlet pipe being greater than the length of the air inlet pipe, and a spiral blade fixedly connected to the outer surface of the rotating shaft, the spiral blade being located inside the inner liner.
[0006] By adopting the above technical solution, the material to be dehydrated is added into the inner liner during use, and high-temperature steam is introduced into the air inlet pipe. The high-temperature steam enters the inner cavity, heats the rotating shaft, and then heats the spiral blades. Afterwards, the high-temperature steam in the inner cavity is discharged from the air outlet pipe. Combined with the high-temperature steam in the steam heating chamber, it heats the inner liner from multiple angles, enabling multi-faceted contact heat transfer to the vacuum dehydrated material in the inner liner. This avoids the problem of clumping caused by the high heat transfer resistance and low heat transfer efficiency of high-viscosity fatty acylmethyl taurate sodium. The motor drives the rotating shaft to rotate, which in turn drives the spiral blades to rotate, which can forcibly stir the material, break up the clumps, increase the heat transfer area, and facilitate the vacuum dehydration of the material.

[0008] A sealing ring is installed between the outer casing and the rotating shaft, and there are two sealing rings.
[0009] By adopting the above technical solution, the sealing ring is a dynamic seal, which can increase the sealing performance of the internal space of the shell and prevent material leakage.
[0010] As a further description of the above technical solution:
[0011] A feed pipe is fixedly connected to the upper surface of the outer shell, and the bottom of the feed pipe is fixedly connected to the outer surface of the inner liner.
[0012] By adopting the above technical solution, the material is added into the inner liner through the feed pipe for vacuum dehydration.

[0014] A flow guide ring is fixedly connected inside the feed pipe, and an air extraction pipe is fixedly connected to the outer surface of the feed pipe, with the air extraction pipe located below the flow guide ring.
[0015] By adopting the above technical solution, air can be extracted from the inner liner through the air extraction pipe, thereby removing moisture.
[0016] As a further description of the above technical solution:
[0017] An end cap is installed at the top of the feed pipe.
[0018] By adopting the above technical solution, the end cap seals the feed pipe.
[0019] As a further description of the above technical solution:
[0020] A discharge pipe is fixedly connected to the lower surface of the outer shell, and the top of the discharge pipe is fixedly connected to the outer surface of the inner liner. A control valve is installed inside the discharge pipe.
[0021] By adopting the above technical solution, the material after vacuum dehydration is discharged from the discharge pipe.
[0022] As a further description of the above technical solution:
[0023] A steam heating chamber is formed between the outer shell and the inner liner. A steam inlet pipe is fixedly connected to the upper surface of the outer shell, and the bottom of the steam inlet pipe is located inside the steam heating chamber. A steam outlet pipe is fixedly connected to the lower surface of the outer shell, and the top of the steam outlet pipe is located inside the steam heating chamber.
[0024] By adopting the above technical solution, high-temperature steam is introduced into the steam heating chamber through the steam inlet pipe to heat the inner liner. When the material comes into contact with the inner liner, it can be heated, which facilitates the removal of moisture from the material.
[0025] By employing the above technical solution, the vacuum dehydration equipment for sodium fatty acylmethyl taurate in high viscosity systems of this utility model has at least the following beneficial effects:
[0026] 1. Compared with existing technologies, this vacuum dehydration equipment for sodium fatty acylmethyl taurate, suitable for high-viscosity systems, adds the material to be dehydrated into the inner liner and introduces high-temperature steam into the air inlet pipe. The high-temperature steam enters the inner cavity, heats the rotating shaft, and then heats the spiral blades. Afterward, the high-temperature steam in the inner cavity is discharged from the air outlet pipe. Combined with the high-temperature steam in the steam heating chamber, it heats the inner liner, enabling multi-faceted contact heat transfer of the vacuum dehydrated material in the inner liner. This avoids the problem of agglomeration caused by high-viscosity sodium fatty acylmethyl taurate due to high heat transfer resistance and low heat transfer efficiency.
[0027] 2. Compared with existing technologies, this vacuum dehydration equipment for sodium fatty acylmethyl taurate, which is suitable for high viscosity systems, uses a motor to drive the rotating shaft, which in turn drives the spiral blades to rotate. This can forcefully stir the material, break up agglomerates, increase the heat transfer area, and facilitate vacuum dehydration of the material. Attached Figure Description
