Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solution purification, in particular to a purification mechanism for HEMA solution. Background Art
[0002] HEMA solution is hydroxyethyl methacrylate, and the HEMA solution is purified according to the use requirements.
[0003] The boiling point of HEMA solution is 95°C (1.333kpa), but the purification purity and effect are not very good when it is purified at about 95°C. HEMA solution will have better purification purity and effect under the condition of 67°C (3.5mmhg (lit). Therefore, a purification mechanism for HEMA solution is proposed to solve the above-mentioned problems. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a purification mechanism for HEMA solution, which can purify the HEMA solution at a temperature below 75° C., thereby solving the above-mentioned problems.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a purification mechanism for HEMA solution, comprising a first lifting platform and a second lifting platform, a constant temperature water bath is arranged on the top of the first lifting platform, a stock solution storage bottle is arranged inside the constant temperature water bath, a distillation tube is arranged on the top of the stock solution storage bottle, a straight condenser is arranged on the right side of the distillation tube, a transfer tube is arranged on the right side of the straight condenser, a filter bottle is connected to the transfer tube through a flexible pipe, and a vacuum pump is connected to the filter bottle through a flexible pipe.
[0006] Furthermore, a waste liquid collection bottle is arranged on the top of the second lifting platform, a valve is arranged on the top of the waste liquid collection bottle, a purification collection bottle is arranged on the top of the valve, and the top of the purification collection bottle is connected to the transfer tube.
[0007] Furthermore, the raw liquid storage bottle is connected to the distillation tube via a waterproof tape, and the connection between the waste liquid collection bottle and the valve is a threaded connection.
[0008] Furthermore, a coolant is arranged in the water cooling tube of the straight condenser tube, and the straight condenser tube is connected to a pumping cooling machine through a flexible pipeline.
[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0010] In the purification mechanism for HEMA solution, the vacuum pump reduces the overall internal air pressure and boiling point of the purification mechanism, so that the HEMA solution in the stock solution storage bottle can boil and evaporate when heated to below 75°C. The evaporated HEMA solution passes through a straight condenser tube and then condenses and enters the purification collection bottle through a transfer tube. During the purification operation, the temperature of the HEMA stock solution in the stock solution storage bottle gradually increases during the heating process. The HEMA purified liquid distilled out at the beginning is not retained. After entering the purification collection bottle, it is collected into the waste liquid collection bottle through the opened valve. After the temperature of the HEMA stock solution in the stock solution storage bottle is stabilized, the valve is closed so that the purified HEMA solution is stored in the purification collection bottle.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0014] See also Figure 1 , an embodiment provided by the utility model:
[0015] A purification mechanism for HEMA solution comprises a first lifting platform 1 and a second lifting platform 9, a constant temperature water bath 2 is arranged on the top of the first lifting platform 1, a stock solution storage bottle 3 is arranged inside the constant temperature water bath 2, a distillation tube 4 is arranged on the top of the stock solution storage bottle 3, a straight condenser 5 is arranged on the right side of the distillation tube 4, a transfer tube 6 is arranged on the right side of the straight condenser 5, a filter bottle 7 is connected to the transfer tube 6 through a flexible pipeline, and a vacuum pump 8 is connected to the filter bottle 7 through a flexible pipeline.
[0016] Furthermore, the first lifting platform 1 serves to support the constant temperature water bath 2 and adjust the height of the constant temperature water bath 2. The constant temperature water bath 2 serves to heat the HEMA stock solution in the stock solution storage bottle 3. The stock solution storage bottle 3 serves to store the HEMA stock solution. The distillation tube 4 serves to transport the heated and evaporated HEMA stock solution.
[0017] Furthermore, the coolant in the water-cooling tube of the straight condenser tube 5 can be circulated and transported by the pumping cooler 13 to maintain a low temperature, thereby cooling and condensing the evaporated HEMA solution to obtain a HEMA finished liquid. The inner core of the straight condenser tube 5 and the transfer tube 6 serve to transport the HEMA finished liquid.
[0018] Furthermore, the filter bottle 7 plays a role in filtering impurities such as oil and gas in the vacuum pump 8. The vacuum pump 8 is connected to the transfer tube 6, which plays a role in reducing the overall internal air pressure and boiling point of the purification mechanism.
[0019] Furthermore, the second lifting platform 9 supports the waste liquid collection bottle 10, the waste liquid collection bottle 10 collects waste liquid, the valve 11 controls the liquid in the purification collection bottle 12 to flow downward, and the purification collection bottle 12 collects HEMA finished liquid.
[0020] Working principle: The vacuum pump 8 reduces the overall internal air pressure and boiling point of the purification mechanism, so that the HEMA solution in the stock solution storage bottle 3 can boil and evaporate when heated to below 75°C. The evaporated HEMA solution passes through the straight condenser 5 and then condenses and enters the purification collection bottle 12 through the transfer tube 6. At the beginning of the purification operation, the HEMA purified liquid enters the purification collection bottle 12 and is then merged into the waste liquid collection bottle 10 through the opened valve 11. After the temperature of the HEMA stock solution in the stock solution storage bottle 3 stabilizes, the valve 11 is closed so that the purified HEMA solution is stored in the purification collection bottle 12.
