Description

Technical Field

[0001] The utility model belongs to the technical field related to industrial production, and particularly relates to a multifunctional 2-ethylanthraquinone refining kettle. Background Art

[0002] 2-Ethylanthraquinone is an important organic chemical raw material, primarily used in the production of hydrogen peroxide, dye intermediates, and photocurable resin catalysts. In industrial production, the purification of 2-ethylanthraquinone is crucial for improving product purity and production efficiency. Traditional refining processes suffer from uneven heating, inefficient stirring, and high energy consumption. To address these issues, researchers and engineers are constantly exploring new refining technologies and equipment designs.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides Figures 1-6 The multifunctional 2-ethylanthraquinone refining kettle shown in the figure comprises a kettle body 1, wherein the left and right sides of the upper end of the kettle body 1 are connected with a feed pipe 2, the front side of the lower end of the kettle body 1 is connected with a slag discharge pipe 3 for discharging the paste slag produced during the refining process, a manhole 4 is provided on the front side of the upper end of the kettle body 1, a filter tube 5 is connected at the center of the upper end of the kettle body 1, and a discharge pipe 6 is connected at the center of the upper end of the filter tube 5, a plurality of supporting legs 7 are fixedly connected to the outer side of the lower end of the kettle body 1, a heating jacket 8 is sleeved on the outside of the kettle body 1, a stirring motor 9 is fixedly connected to the center of the lower end of the kettle body 1, a stirring shaft 10 is rotatably connected to the center of the upper end of the stirring motor 9 through a rotating shaft, and the stirring shaft 10 is rotatably connected to the inside of the kettle body 1, and the rotating shaft passes through the center of the lower end of the kettle body 1, a plurality of upward stirring blades 11 are provided on the lower side of the stirring shaft 10, and the plurality of upward stirring blades 11 are fixedly connected to the outside of the rotating shaft. In the process of refining 2-ethylanthraquinone, the crude 2-ethylanthraquinone solution is fed into the kettle body 1 through the two feed pipes 2. The crude solution is introduced into the vacuum kettle body 1, and the heating jacket 8 on the outside of the kettle body 1 heats and evaporates the crude solution inside. The evaporated 2-ethylanthraquinone passes through the filter element provided in the filter tube 5 for filtration, and then is discharged through the outlet pipe 6 and condensed, thereby refining the crude solution of 2-ethylanthraquinone to obtain a more refined 2-ethylanthraquinone. The vacuum kettle body 1 can effectively lower the boiling point of the crude solution and improve the evaporation efficiency of 2-ethylanthraquinone. During heating and evaporation, the heated crude solution is stirred by the stirring shaft 10, causing the crude solution to rotate horizontally inside the kettle body 1. At the same time, the crude solution is pushed upward by multiple upwelling stirring blades 11 on the lower side of the stirring shaft 10, causing the crude solution to surge vertically inside the kettle body 1, making the heating of the crude solution more uniform, improving the temperature uniformity inside the crude solution, and preventing the formation of sediment and resulting in the formation of paste residue, thereby improving the refining efficiency and quality of 2-ethylanthraquinone.

[0030] Preferably, a limited fixing ring 12 is fixedly connected to the upper side of the cylindrical inner wall of the kettle body 1, and the lower end of the limited fixing ring 12 and the upper end of the inner wall of the lower end of the kettle body 1 are both rotatably connected to a limited rotating ring 13.

The two limiting rings 13 can rotate inside the kettle body 1 through the plurality of balls 15 and the two rolling grooves 16, and can reduce the friction between the inner wall of the kettle body 1 and the inner wall of the kettle body 1 by the rolling of the plurality of balls 15 in the rolling grooves 16, which can not only improve the service life of the limiting ring 13, but also reduce energy loss, making it more energy-efficient.

[0032] Preferably, a plurality of connecting rods 21 are connected to the outer side of the upper end of the heating sleeve 8, and the plurality of connecting rods 21 are all inserted into the upper end of the kettle body 1, and a heating rod 22 is connected to the side of the lower end of the plurality of connecting rods 21 away from the support leg 7, and the plurality of heating rods 22 are all located between the stirring shaft 10 and the plurality of outer stirring paddles 14. In the process of heating the test solution, the crude solution can be externally heated by the heating sleeve 8 outside the kettle body 1, and can also be internally heated by the plurality of heating rods 22 between the stirring shaft 10 and the plurality of outer stirring paddles 14, thereby improving the heating efficiency, and further improving the refining efficiency of 2-ethylanthraquinone.
