Description

Technical Field

[0001] The utility model relates to the technical field of purification devices, in particular to a purification device in the production of chemical reagents. Background Art

[0002] In the production process of chemical reagents, purification is a crucial link. High-purity chemical reagents play a key role in many fields such as scientific research, pharmaceutical manufacturing, and the electronics industry. With the continuous development of various industries, the purity requirements for chemical reagents are getting higher and higher. Traditional purification methods and devices are gradually unable to meet the needs. Therefore, the development of efficient and accurate chemical reagent purification devices has become an important topic in the current chemical field. New purification devices need to improve purification efficiency while reducing energy consumption and reducing impurity residues to adapt to the ever-evolving market demand.

[0003] Common chemical reagent purification devices mainly use a simple combination of distillation and filtration. The distillation part usually heats the chemical reagent to boiling, turning the volatile components into steam, and then cools the steam into liquid through a condenser to achieve preliminary separation. The filtration part mostly uses a single filter medium, such as filter paper or filter mesh, to simply filter the distilled reagent to remove solid particulate impurities. The technical principle of this traditional device is relatively simple, relying on the differences in the physical properties of the substances for separation.

[0004] The chemical reagent purification device in the prior art has the problem of concentrated heating area during the distillation process, which leads to low heating efficiency. Since the heating is concentrated at the bottom, the temperature distribution inside the reagent is uneven. Some reagents may decompose or deteriorate due to local overheating, affecting product quality. At the same time, the concentrated heating area also causes large heat loss, and more energy is required to maintain the distillation process. This uneven heating method will also affect the steam generation speed and quality, thereby reducing the working efficiency of the entire purification device. In addition, the traditional device also has deficiencies in the filtration link and cannot effectively remove ionic impurities, further affecting the purity of the chemical reagent. For this reason, a purification device for chemical reagent production is proposed to solve the above problems. Utility Model Content

The side wall of the filter 22 is fixedly connected with a support frame 23. The support frame 23 is made of aluminum alloy and has high The strength and stability of the filter 22 are ensured by welding. The support frame 23 is fixed to the side wall of the filter 22 to provide stable support for the filter 22. The bottom of the support frame 23 is fixedly connected to the top of the base 1 to ensure the stability of the position of the entire filter assembly. The top of the filter 22 is fixedly connected to the booster pump 21. The input end of the booster pump 21 is fixedly connected to one end of the output pipe 20.

The inner wall of the filter 22 is fixedly connected to a support arm 27. The support arm 27 is made of corrosion-resistant stainless steel and has high strength and rigidity. The support arm 27 is firmly fixed to the inner wall of the filter 22 by welding, providing stable support for the push rod 28. The side wall of the support arm 27 is fixedly connected to the push rod 28. The outer shell of the push rod 28 is made of aluminum alloy, which has good heat dissipation performance and corrosion resistance.

After the work is completed, the chemical reagent is pumped out by the liquid suction pump 19 and output to the next link through the output pipe 20. This achieves efficient and rapid purification of chemical reagents. When the chemical reagent enters the booster pump 21 from the output pipe 20, the booster pump 21 starts working to pump the reagent into the filter 22. The reagent first passes through the filter layer 1 25 and then through the filter layer 2 26, and then flows into the space between the filter layer 2 26 and the filter layer 3 31. At this time, the push rod 28 starts working to push the movable rod 29 to move. The displacement of the movable rod 29 pushes the displacement of the piston 30, and squeezes out the solvent and passes through the filter layer 3 31, and finally flows into the receiving barrel 24, thereby achieving the effect of quickly filtering ionic impurities in the chemical reagent.
