Description

Technical Field

[0001] The utility model belongs to the technical field of extraction heating equipment, and specifically relates to a new type of heating equipment used for experimental extraction. Background Art

[0002] In the process of chemical analysis, it is usually necessary to extract the substance to be tested before measuring it. Extraction, also known as solvent extraction or liquid-liquid extraction, is an operation to separate a mixture by using the different solubilities of the components in the system in the solvent. That is, the solute substance is transferred to another solvent by using the difference in solubility or distribution coefficient of the substance in two immiscible (or slightly soluble) solvents. In the analytical experiment, appropriately increasing the extraction temperature is conducive to improving the extraction efficiency of the substance, and heating equipment is required during the extraction process.

[0003] The existing commercially available equipment commonly used in the heating process includes electric heating sleeves, water baths and other equipment. The heating process usually involves placing round-bottom flasks, conical flasks, flat-bottom flasks, etc. in the heating equipment for heating. The electric heating sleeve is small in size and easy to use, but there is a problem of uneven heating during the heating process due to the shape and size of the heating container not matching the electric heating sleeve. Sometimes the local temperature is too high, which will cause the heated extracted material to burn, and the solution is easily evaporated during heating, resulting in unstable experimental data and experimental failure. When a water bath is used for the heating extraction and distillation process, due to its large volume, more liquid needs to be injected, and it needs to be heated in advance before the experiment is prepared, which takes a long time; and if the liquid level in the pot is high, the glass container to be extracted is easy to float upside down when it is placed in it, causing the experiment to fail; because when the experimental container is placed in the water bath, the bottom of the extraction container is directly in contact with the bottom of the water bath, and sometimes when the bottom plate temperature is too high, the bottom of the glass container is easy to break, causing danger and experimental failure.

[0004] Therefore, it is necessary to provide a new type of heating equipment for experimental extraction, which can make the extraction container heated more evenly and heat in the medium solution, so that the liquid in the container is not easy to evaporate or burn, the experimental results are more stable, and the extraction efficiency is improved.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0019] like Figure 1 As shown, the novel heating device for experimental extraction comprises an outer tank 1, a temperature control system 2, a rotating table 3, a rotating table controller 4, an elastic steel wire sleeve 5, and a bell-mouth silicone container fixing sleeve 6; the outer tank 1 is made of a high temperature resistant material, which can hold water, mineral oil, other aqueous solutions, etc. The medium solution in the outer tank 1 can be selected to add solutions of different boiling points according to experimental requirements, such as water, glycerin, silicone oil, etc., and a liquid level scale line 9 is provided on the outer tank 1 for measuring and observing the height of the solution in the outer tank 1. A heat preservation cover 8 is installed on the outer tank 1 through a heat preservation cover telescopic arm 7, and the heat preservation cover 8 is adjusted in height by the heat preservation cover telescopic arm 7.

[0020] A temperature control system 2 is arranged in the outer tank 1. A digital temperature adjustment knob 21 electrically connected to the temperature control system 2 is provided on the outer wall of the outer tank 1. The temperature in the heating device is displayed and adjusted by the digital temperature adjustment knob 21. A rotating table 3 is installed at the bottom of the inner cavity of the outer tank 1. The rotating table 3 is made of a material that is resistant to high temperature, oil and water immersion, and is not easy to deform. The rotating table 3 is electrically connected to the rotating table controller 4. A rotating table speed adjustment knob 41 electrically connected to the rotating table controller 4 is provided on the outer wall of the outer tank 1. The rotating table speed adjustment knob 41 is used to adjust the speed and start and stop of the rotating table 3.

[0021] A bird's nest-like elastic steel wire sleeve 5 is installed on the rotating table 3. The rotating table 3 rotates to drive the elastic steel wire sleeve 5 to rotate, so that the extracted solution forms a vortex in the container, thereby improving the extraction efficiency. At the same time, the rotation can also make the heating more uniform and the detection result more stable. The extraction vessel 11 is placed in the elastic steel wire sleeve 5. The bird's nest-like elastic steel wire sleeve 5 can better wrap and fix the inserted extraction vessel 11, and the steel wire sleeve is elastic, so containers of different sizes can be used, and the application range is wide.

[0022] The heat preservation cover 8 is provided with a circular through hole, and the bell-mouthed silicone container fixing sleeve 6 is installed in the outer liner 1 through the circular through hole and is located directly above the elastic wire sleeve 5. The bell-mouthed silicone container fixing sleeve 6 is a hollow structure, and its lower section is a bell-mouthed silicone container, and its upper section is a tubular structure that can be clipped and retracted. When the solution is heated, the upper section of the bell-mouthed silicone container fixing sleeve 6 is stretched and fixed by clips, and the heat preservation cover 8 is put down. The diameter of the extraction vessel 11 in the elastic wire sleeve 5 can be just inserted into the bell mouth of the bell-mouthed silicone container fixing sleeve 6, which can play a certain role in preventing tipping. At the same time, when the heating is completed, When the heat preservation cover 8 is opened, the bell-mouth silicone sleeve section of the bell-mouth silicone vessel fixing sleeve 6 on the heat preservation cover 8 can fix the caliber of the heated extraction vessel 11 by utilizing its own elastic characteristics to lift the extraction vessel 11. In addition, due to the friction between the caliber of the extraction vessel 11 and the bell-mouth silicone sleeve, the extraction vessel 11 can be suspended in the air to cool down and removed after cooling, so as to avoid the operator taking it out by hand and prevent burns. When the device is not in use, the bell-mouth silicone vessel fixing sleeve 6 can be contracted as a whole by the snap-fit ​​and retractable tubular structure of the upper section of the bell-mouth silicone vessel fixing sleeve 6, so as to facilitate storage and placement.

[0023] A tying and fixing belt 10 is provided on one section of the flared silicone sleeve of the flared silicone vessel fixing sleeve 6, which can assist in fixing the extraction vessel 11 when the extraction vessel 11 is lifted after the solution is heated, thereby preventing the extraction vessel 11 from falling.

[0024] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
