Description

Technical Field

[0001] The utility model relates to the technical field of material preparation, in particular to an emulsification device for preparing BDO. Background Art

[0002] 1,4-Butanediol (BDO), an important organic chemical and fine chemical raw material, appears as a colorless or pale yellow oily liquid. It is soluble in methanol, ethanol, acetone, and slightly soluble in ether. It is flammable and highly soluble. In the field of engineering plastics, BDO is a basic raw material for the production of polybutylene terephthalate (PBT) engineering plastics and PBT fibers. PBT plastics have excellent heat resistance, weather resistance, and mechanical properties, making it one of the most promising of the five major engineering plastics. In addition, BDO is the main raw material for the production of tetrahydrofuran (THF), a key organic solvent. The resulting polytetramethylene glycol ether (PTMEG) is the basic raw material for the production of highly elastic spandex (Lycra fiber).

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0028] It should be noted that the emulsification equipment is preferably suitable for emulsification preparation in the production of high-viscosity or high-concentration 1,4-butanediol (BDO).

[0029] like Figure 1 、 Figure 3 and Figure 4 As shown, an emulsification apparatus for preparing BDO comprises: an emulsification tank 1, a support assembly disposed at the bottom of the emulsification tank 1 for supporting and stabilizing the emulsification tank, and a stirring and emulsifying assembly mounted within the emulsification tank 1; the stirring and emulsifying assembly comprises: a servo motor 2 mounted on the top of the emulsification tank 1, a rotating rod 21 disposed within the emulsification tank 1, and a plurality of stirring rods 22 fixed to the sides of the rotating rod 21; stirring cones 23 are fixed to both ends of the stirring rods 22, and the output end of the servo motor 2 is fixed to the top end of the rotating rod 21; the stirring cones 23 are hollow frustum structures; in the planar direction and in the vertical direction, the larger diameter ends and smaller diameter ends of adjacent stirring cones 23 face opposite directions.

[0030] It should be noted that the side of the rotating rod 21 near the top is rotatably connected to the inner side of the emulsification tank 1 through a bearing; a plurality of stirring rods 22 are distributed on the side of the rotating rod 21 in a linear array; after the material for BDO emulsification is placed inside the emulsification tank 1, the servo motor 2 on the top of the emulsification tank 1 is started to drive the rotating rod 21 at the output end to rotate, thereby driving the plurality of stirring rods 22 on the side of the rotating rod 21 and the stirring cones 23 at both ends of the stirring rod 22 to rotate synchronously. Since the larger diameter end and the smaller diameter end of the adjacent stirring cones 23 are oriented in the same direction in the plane direction and the vertical direction, the rotating rod 21 is rotated synchronously with the stirring rod 22 on the side of the rotating rod 21. On the contrary, in the same rotation direction, a part of the stirring cone 23 first brings in the material at the end with a larger diameter, so that the material is strongly squeezed and sheared when it is discharged to the end with a smaller diameter, which helps to refine the large particles of the material and promote the full mixing of the oil phase and the water phase. The other part of the stirring cone 23 first brings in the material at the end with a smaller diameter, so that the material is pushed to the wall of the emulsification tank 1 when it is discharged to the end with a larger diameter, and then flows back to the end with a smaller diameter of the stirring cone 23 under the action of gravity and the stirring rod 22, forming a circular flow, which helps to distribute and mix the material more evenly and improve its emulsification efficiency.

[0031] like Figure 4 As shown, in some embodiments, a plurality of stirring blades 3 are symmetrically fixed to the side of the stirring rod 22 , and a plurality of dispersion holes 31 are opened on the surface of the stirring blades 3 .

[0032] It should be noted that several stirring blades 3 are arranged perpendicular to the stirring rod 22; when the stirring rod 22 rotates to stir the material, the stirring blades 3 will rotate synchronously with the stirring rod 22, and the material will be further squeezed and sheared when passing through the dispersion holes 31 on the stirring blades 3, thereby being able to quickly and effectively refine the material, which helps to improve the emulsification effect.

[0033] like Figure 3 As shown, in some embodiments, the middle portion of the emulsification tank 1 is straight-cylindrical and the bottom is arc-shaped, which can prevent the BDO raw material from accumulating at the bottom of the emulsification tank 1 to form a dead zone.

[0034] In some embodiments, a heating layer 4 is provided inside the emulsification tank 1 , and the heating layer 4 is heated by heat conduction or heat radiation. The provision of the heating layer 4 can provide the required emulsification temperature during BDO emulsification.

[0035] In some embodiments, a feed cylinder 5 is fixed to the top of the emulsification tank 1, a discharge cylinder 51 is fixed to the bottom of the emulsification tank 1, and a valve 52 is installed on the side of the discharge cylinder 51; the interiors of the feed cylinder 5 and the discharge cylinder 51 are both connected to the interior of the emulsification tank 1; through the provision of the feed cylinder 5, the raw materials for the emulsification preparation of BDO can be added to the interior of the emulsification tank 1, and through the provision of the discharge cylinder 51, after emulsification is completed, the valve 52 is opened to discharge the emulsified material through the discharge cylinder 51.

[0036] In some embodiments, an air inlet pipe 6 for providing the required gas during emulsification is fixed to the top of the emulsification tank 1, and the interior of the air inlet pipe 6 is connected to the interior of the emulsification tank 1; through the setting of the air inlet pipe 6, during emulsification, the top end of the air inlet pipe 6 is externally connected to the gas delivery device, thereby being able to deliver the gas environment during emulsification, such as hydrogen and nitrogen, to the interior of the emulsification tank 1.

[0037] In some embodiments, a pressure gauge 7 for monitoring the internal pressure of the emulsification tank 1 is installed on the top of the emulsification tank 1 , and a temperature gauge 71 for monitoring the internal temperature of the emulsification tank 1 is installed on the side of the emulsification tank 1 .

[0038] like Figure 1 As shown, in some embodiments, an observation window 8 for observing the internal conditions of the emulsification tank 1 is provided on the side of the emulsification tank 1; the provision of the observation window 8 facilitates the staff to observe the internal conditions of the emulsification tank 1 from the outside.

[0039] like Figure 1As shown, in some embodiments, the support assembly includes: a base 9 arranged at the bottom of the emulsification tank 1, and a support frame 91 fixed to the top of the base 9; one side of the support frame 91 is fixed to the side of the emulsification tank 1; through the fixation of the support frame 91, the emulsification tank 1 can be supported, and through the setting of the base 9, it can be placed stably.

[0040] When the present invention is used, the material to be emulsified by BDO is placed inside the emulsification tank 1 through the feeding barrel 5. The top end of the air inlet pipe 6 is connected to the gas delivery device to deliver the gas environment during emulsification to the inside of the emulsification tank 1. The required emulsification temperature is provided by the heating layer 4. The servo motor 2 on the top of the emulsification tank 1 is started to drive the rotating rod 21 at the output end to rotate, thereby driving the multiple stirring rods 22 on the side of the rotating rod 21 and the stirring cones 23 at both ends of the stirring rod 22 to rotate synchronously. Since the larger diameter end and the smaller diameter end of the adjacent stirring cones 23 are in opposite directions in the plane direction and the vertical direction, in the same rotation direction, the larger diameter end of a part of the stirring cones 23 first brings in the material. The material is first brought into the mixing cone 23 at the end with a smaller diameter, so that when the material is discharged to the end with a larger diameter, it is pushed to the wall of the emulsification tank 1, and then flows back to the end with a smaller diameter of the mixing cone 23 under the action of gravity and the stirring rod 22, forming a circular flow, which helps to distribute and mix the material more evenly and improve its emulsification efficiency. At the same time, the stirring blade 3 will rotate synchronously with the stirring rod 22, and the material will be further squeezed and sheared when passing through the dispersion holes 31 on the stirring blade 3, thereby being able to quickly and effectively refine the material and helping to improve the emulsification effect.
