[0002] Hydroxyethylpiperazine is a biochemical agent that is used in both biological materials and organic compounds. According to relevant scientific research, hydroxyethylpiperazine can be used to make hydroxyethylpiperazine ethane sulfonic acid, which is used in the cosmetics industry and has the effect of removing skin keratin when used on the skin. The existing production and preparation of hydroxyethylpiperazine requires physical mixing, which uses a mixing device mixing tank. When the mixing tank is used, the mixing is stirred and mixed by a stirring shaft. The existing ordinary stirring shaft has a long mixing time and can only rotate in one direction for mixing. The mixing is not thorough enough and the mixing time is long, which affects the preparation of hydroxyethylpiperazine. Utility Model Content

[0006] Preferably, the first mixing tank and the second mixing tank are in the shape of round cakes.
[0007] Preferably, a filter screen is fixed on the inner wall of the feed inlet.
[0008] Preferably, the horizontal symmetry axis of the connecting pipe coincides with the horizontal symmetry axis of the first mixing tank and the second mixing tank.
[0009] Preferably, the width of the connecting pipe is the same as the width of the first mixing tank, and the height of the connecting pipe is the length of the radius of the first mixing tank.
[0010] Preferably, the stirring blade inside the first mixing tank rotates in the opposite direction to the stirring blade inside the second mixing tank.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] By arranging a first mixing tank, a second mixing tank, a telescopic cylinder and a reduction motor, the materials are inside the first mixing tank, the height of the first mixing tank is lower than that of the second mixing tank, and are mixed by the stirring blades inside the first mixing tank. When the telescopic cylinder is extended to raise the first mixing tank above the first mixing tank, the materials enter the second mixing tank and are mixed by the reversed stirring blades in the second mixing tank, thereby achieving an effect that the two sets of mutually reversed stirring blades stir the materials in two areas respectively, solving the problem that the existing mixing tube only mixes in one direction through the stirring shaft, resulting in incomplete mixing and a long mixing time.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] See also Figures 1 to 4In an embodiment of the utility model, a mixing device for preparing hydroxyethylpiperazine comprises a first mixing tank 1 and a placing table 2. A telescopic cylinder 3 is rotatably arranged at a position near one side of the top of the placing table 2 for raising and lowering the first mixing tank 1. A rotating head 4 is fixed at the top of the telescopic cylinder 3. The rotating head 4 rotates at the bottom of the first mixing tank 1. A positioning plate 5 is fixed at a position near the other side of the top of the placing table 2 for supporting and stabilizing a rotating second mixing tank 6. A second mixing tank 6 is rotatably arranged on the positioning plate 5. The first mixing tank 1 and the second mixing tank 6 are in the shape of round cakes. Such a configuration can fit the width and length of the stirring blade 11, so that the stirring blade 11 can better stir the materials and mix them.
[0020] A connecting pipe 7 is provided between the second mixing tank 6 and the first mixing tank 1, and the horizontal symmetry axis of the connecting pipe 7 coincides with the horizontal symmetry axis of the first mixing tank 1 and the second mixing tank 6. The purpose of the intermediate position design is to make less material remain in the connecting pipe 7 after the material enters the first mixing tank 1 and the second mixing tank 6, so as to avoid insufficient mixing. If the connecting pipe 7 is arranged close to the top, it is impossible to make the material flow well between the first mixing tank 1 and the second mixing tank 6. The width of the connecting pipe 7 is the same as that of the first mixing tank 1, and the height of the connecting pipe 7 is the same as that of the first mixing tank 1. The length of the radius of the mixing tank 1, a feed port 8 is arranged on the top of the first mixing tank 1, a filter screen 14 is fixed on the inner wall of the feed port 8 for filtering the material, a discharge port 9 is arranged on the side of the second mixing tank 6 near the bottom, a rotating shaft 10 is rotated inside the first mixing tank 1 and the second mixing tank 6, a stirring blade 11 is fixed on the surface of the rotating shaft 10, the stirring blade 11 inside the first mixing tank 1 and the stirring blade 11 inside the second mixing tank 6 rotate in the opposite direction, a reduction motor 12 is fixed on the back of the first mixing tank 1 and the second mixing tank 6, and the output of the reduction motor 12 The output shaft is fixedly connected to the end face of the rotating shaft 10, and a support rod 13 is provided at the bottom of the placing table 2. The placing table 2 is stably placed on the ground through the support rod 13. When mixing, hydroxyethyl piperazine needs to be firstly put into the first mixing tank 1 through the feeding port 8, and then the telescopic cylinder 3 is contracted to make the height of the first mixing tank 1 lower than the second mixing tank 6. The hydroxyethyl piperazine is gathered in the first mixing tank 1 and then the reduction motor 12 is started. The reduction motor 12 drives the stirring blade 11 to rotate in the first mixing tank 1 through the rotating shaft 10, and drives the hydroxyethyl piperazine to mix. During the mixing process, the second mixing tank The stirring blades 11 inside the combining tank 6 also rotate in the opposite direction. During the mixing process, the telescopic cylinder 3 is extended to drive the first mixing tank 1 to a height higher than the second mixing tank 6. After the hydroxyethyl piperazine flows into the second mixing tank 6 through the connecting pipe 7, the stirring blades 11 rotating in the opposite direction also reversely mix the hydroxyethyl piperazine. Then, during the extension and contraction of the telescopic cylinder 3, the hydroxyethyl piperazine reciprocates between the first mixing tank 1 and the second mixing tank 6 for mixing, thereby achieving a better mixing effect, and achieving the effect of two sets of mutually reversed stirring blades 11 stirring the materials in two areas respectively.
