Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature oil bath equipment, and more specifically to a constant temperature oil bath pot. Background Art

[0002] At present, with the development of science and technology, the frequency of scientific experiments is gradually increasing. In the existing reflux condensation experiments, constant temperature oil bath pots and condensers are often used. The flask containing liquid is heated by the constant temperature oil bath, so that the liquid vaporizes and enters the inner tube of the condenser, and then cools and refluxes. When testing polyester polyols, the constant temperature oil bath can ensure that the reaction system is carried out at a constant temperature. At a constant temperature, the acylating agent (such as acetic anhydride) can react more fully with the hydroxyl group in the sample, thereby improving the accuracy of the hydroxyl value determination.

[0003] Most of the existing cooling of the inner tube in the condenser uses some water circulation equipment to reuse the cooling water, and often uses a water pump to transport water for cooling. After long-term use, the cooling water absorbs a large amount of heat and the temperature will gradually rise, which will cause the condensation effect to gradually decrease. In addition, the condensed water contains minerals. These minerals will leave deposits on the outer surface of the inner tube of the condenser when heated. The condensed water will take away some of the deposits on the outer surface of the inner tube of the condenser when it passes through the outer surface of the inner tube of the condenser. These deposits pass through the water pump and accumulate in the water pump for a long time, which will cause damage to the water pump. Utility Model Content

[0025] In the present embodiment, when in use, the experimenter connects the flask containing the experimental liquid to the inner tube of the condenser 2, and puts the flask into the constant temperature oil pot 1, firstly transports the cooling water in the water tank 3 into the condenser 2 through the input component 5, so that the cooling water enters through the water inlet of the condenser 2, and the cooling water exists in the gap between the inner tube and the outer tube of the condenser 2, so that the cooling water rises to the water outlet of the condenser 2 and flows out through the water outlet of the condenser 2, and transports the cooling water into the water tank 3 through the output component 6, so that the cooling water can be recycled and resources can be saved.

[0027] In this embodiment, the cooling water in the water tank 3 is transported into the water inlet pipe 501 by the water pump 502, so that the cooling water enters the first hose 503 through the water inlet pipe 501, and enters the gap between the inner tube and the outer tube of the condenser 2 through the first hose 503, thereby cooling the gas entering the inner tube of the condenser 2.

[0028] Specifically, the output component 6 includes a water outlet pipe 601, several second hoses 602 and a connecting pipe 603.

At this time, the staff takes the annular filter screen 708, the fixing plate 707 and the second magnet 706 out of the slot 704 at an angle, and manually cleans the sediment on the annular filter screen 708. When the cleaning is completed, the staff puts the annular filter screen 708, the fixing plate 707 and the second magnet 706 into the water tank 3 at an angle from the slot 704, so that the first magnet 705 and the second magnet 706 are attracted to each other, and the annular filter screen 708 is fixed. The sediment is filtered by the annular filter screen 708 to prevent the sediment from entering the water pump 502 and causing damage to the water pump 502.
