Description

Technical Field

[0001] This utility model relates to the technical field of filtration and liquid separation devices, specifically to an integrated vacuum filtration and liquid separation device. Background Technology

[0002] Vacuum filtration, also known as reduced pressure filtration, uses a vacuum pump to remove air from the filtration flask, creating a negative pressure environment that accelerates the filtration of the solution from the funnel into the flask, thus achieving rapid solid-liquid separation. In chemical experiments, separatory funnels are commonly used to extract, separate, or purify specific components from solutions. In chemistry, biomedicine, physics, materials science, and many other fields, performing separation after vacuum filtration is a very common experimental procedure.

[0003] Existing laboratory filtration and separation devices operate directly in an open environment. During operation, the temperature inside the liquid is easily affected by external temperature, pressure, solvent evaporation, etc., causing drastic changes that affect the separation effect. Furthermore, strict control of operating procedures and stability is required, resulting in high operational difficulty and material loss rate. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] like Figure 1 As shown, in one embodiment, an integrated filtration and separation device includes: a filtration funnel 1, a separation funnel 2, and a jacket 7. The filtration funnel 1 is disposed above the separation funnel 2.

[0025] Furthermore, a jacket 7 is provided on the outside of the filtration funnel 1 and the separating funnel 2. The jacket 7 is used to heat the filtration funnel 1 and the separating funnel 2. The filtration funnel 1 and the separating funnel 2 are integrally formed, and the materials of the filtration funnel 1, the separating funnel 2 and the jacket 7 are glass. While ensuring the airtightness of the operation, the filtration funnel 1 and the separating funnel 2 are kept at the same temperature environment through circulating heating, which can be better suited for isothermal filtration and separation operations with different temperature requirements.

[0026] Please continue reading Figure 1 The filtration funnel 1 is a glass plate funnel with a filter plate in the middle for placing filter media. The filter plate is a flat circular or conical glass plate with a perforated grid. Filter media is placed on the filter plate to cooperate with filtration. The filter media can be one or both of filter paper and filter cloth, allowing liquid to pass through while effectively filtering impurities.

[0027] Furthermore, a suction port 3 is provided on one side of the bottom of the suction funnel 1. The suction port 3 extends through the jacket 7 to the outside of the jacket 7, and a vent valve 4 is provided on the suction port 3. In use, the suction port 3 is connected to a vacuum pump to provide a low-pressure environment, while the vent valve 4 is used to allow air to pass through and break the low-pressure environment of the suction funnel 1.

[0028] Please continue reading Figure 1 A temperature measuring port 10 is provided on one side of the top of the separating funnel 2. The temperature measuring port 10 extends through the jacket 7 to the outside of the jacket 7. A liquid discharge port 6 is provided at the bottom of the separating funnel 2, and a liquid discharge valve 5 is provided in the middle of the liquid discharge port 6. In use, a thermometer is inserted through the temperature measuring port 10 to measure the temperature of the heat-conducting liquid in the jacket 7. When temperature measurement is not required, it can be sealed by a stopper. After the filtration and separation operations are completed, the liquid discharge valve 5 is opened to allow the liquid to flow out from the liquid discharge port 6.

[0029] Please continue reading Figure 1 The filtration funnel 1 and the separating funnel 2 are equipped with a jacket 7 for circulating heating of the filtration funnel 1 and the separating funnel 2. The jacket 7 is provided with a circulating liquid inlet 8 and a circulating liquid outlet 9. The circulating liquid inlet 8 is located on one side of the bottom of the separating funnel 2, and the circulating liquid outlet 9 is located on the other side of the top of the filtration funnel 1.

[0030] Working principle: The filtration funnel 1 and the separating funnel 2 are surrounded by a jacket 7. The heat transfer fluid enters through the lower circulating fluid inlet 8, passes through the filtration funnel 1 and the separating funnel 2, and flows out from the upper circulating fluid outlet 9, providing a stable temperature environment for operation. The air extraction port 3 and the air release valve 4 are located on one side of the separating funnel 2 to regulate and control the internal air pressure environment, while the thermometer socket is located on the top side of the separating funnel 2 for convenient temperature monitoring. The liquid discharge valve 5 and the discharge port are located at the bottom of the separating funnel 2 to facilitate the collection of the processed liquid.

[0031] Through the above technical solution, this application realizes the filtration and separation operation in a closed environment, ensuring that the temperature of the filtration funnel 1 and the separation funnel 2 is kept consistent, effectively reducing the difficulty of operation and the material loss rate.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
