Description

Technical Field

[0001] The present application relates to the technical field of isopropyl alcohol processing, and in particular to a stirring adsorption device for pharmaceutical-grade isopropyl alcohol with low ultraviolet absorption. Background Art

[0002] Isopropyl alcohol is a colorless, transparent liquid with an odor similar to a mixture of ethanol and acetone. It is soluble in water and most organic solvents such as alcohol, ether, and chloroform. Isopropyl alcohol is an important chemical product and raw material, mainly used in the pharmaceutical, cosmetic, plastic, fragrance, coating and other industries. It is widely used in industry as a solvent. At the same time, isopropyl alcohol plays a very important role as a solvent in pharmaceutical production.

[0003] Take 5000ML of industrial-grade isopropyl alcohol, add impurity remover potassium borohydride at a ratio of 3g / L, heat to react for 2 hours, and stop heating after the reflux reaction is complete. After the material cools to room temperature, add 6 grams of powdered activated carbon, stir and adsorb for 3 hours, then filter and separate the activated carbon. Then add 6 grams of reducing dehydrating agent calcium hydride to the filtered isopropyl alcohol, heat to reflux and dehydrate for 2 hours, heat and distill, and collect isopropyl alcohol in the range of 82-83°.

[0004] After completing the stirring and adsorption work, the activated carbon and isopropyl alcohol are filtered and separated through the filter. During the separation process, the activated carbon will stick to the surface of the filter. At this time, part of the activated carbon will clog the filter mesh, resulting in a slow separation speed of isopropyl alcohol. Utility Model Content

[0035] A guide rod 504 is provided inside the fixed frame 503 to provide stability to the structure on the rod during displacement. A filter plate 505 is provided outside the guide rod 504 to perform filtering and separation. A spring 506 is provided above the filter plate 505 to facilitate vertical extrusion.

[0036] The guide rod 504 is vertically welded to the inner side of the "C"-shaped plate of the fixed frame 503, which provides stability when limiting;

[0037] The filter plate 505 can be displaced vertically on the guide rod 504, facilitating the vibration effect brought about by the subsequent vertical displacement;

[0038] The spring 506 is welded on the top of the filter plate 505, and the spring 506 facilitates the vertical extrusion work; and the spring 506 is arranged on the outside of the guide rod 504, which makes it very stable when providing the extrusion work.

[0046] The implementation principle of the low UV absorption pharmaceutical grade isopropyl alcohol stirring adsorption device of the present application is as follows:

[0047] First, isopropyl alcohol is added with potassium borohydride, an impurity remover, for heating reaction. After the temperature is cooled to room temperature, powdered activated carbon is added and motor 2 is started. When motor 2 rotates, shaft 3 on the output end is driven to rotate. When shaft 3 rotates, the stirring blade 4 on the shaft is driven to rotate synchronously, thereby completing the stirring work. At this time, the activated carbon will adsorb the impurities in the isopropyl alcohol.

[0048] Secondly, when the activated carbon and isopropyl alcohol need to be filtered and separated, the baffle 602 is rotated by connecting the rotating shaft 601. At this time, the baffle 602 is in a vertical state, which can limit the fixed frame 503 and prevent the internal structure of the fixed frame 503 from shifting during vertical displacement.

[0049] Finally, motor 507 is started, driving shaft 508 on the output end to rotate. This rotation drives the curved block 509 on the shaft, which then moves the filter plate 505 above. Guide rod 504 allows the filter plate 505 to move stably. As the filter plate 505 rises, it is squeezed by spring 506 and lowered back to its original position, causing vibration. This effectively prevents clogging during filtration. It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above and that other specific forms of the present application can be employed without departing from the spirit or essential features of the present application. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects. The scope of the present application is defined by the appended claims, not the foregoing description, and all variations that fall within the meaning and scope of equivalents of the claims are intended to be encompassed within the present application. Any reference numerals in the claims should not be construed as limiting the claims to which they relate.
