Description

Technical Field

[0001] This utility model relates to the technical field of reflux extraction devices, specifically a heating reflux extraction device for effective components of samples. Background Technology

[0002] Reflux extraction is an extraction method that uses volatile organic solvents to heat and circulate the sample raw material for extraction. Its core principle is to use a distillation device to condense the solvent vapor and reflux it back to the raw material container, forming a continuous extraction cycle. It is suitable for the efficient extraction of heat-stable components. This method requires a reflux condenser and a water bath heating system to maintain a boiling state, and the extraction is carried out in stages until all the effective components are extracted.

[0003] Existing heating reflux extraction devices typically consist of a water bath, a beaker, and a condenser. The water bath heats the beaker, causing the sample inside to boil and react. The condenser then refluxes the sample to achieve a circulating extraction. However, the condenser's inlet is usually directly connected to an external water tap, ensuring a continuous water supply. Since the water is discharged directly after condensation, the condenser requires a constant water supply to maintain its cooling effect, thus wasting water resources.

[0004] Therefore, this invention provides a sample active ingredient heating and reflux extraction device to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4As shown, this utility model provides a sample effective component heating reflux extraction device, including a water bath host 1, which includes a water bath tank 11, an equipment box 12 fixedly connected to one side of the water bath tank 11, and a circulating water tank 13 fixedly connected to the other side of the water bath tank 11; a water bath assembly 2, which includes a water bath mesh frame 21, which is placed inside the water bath tank 11, and a beaker 5 is placed inside the water bath mesh frame 21; a cover plate 22 is fixedly connected to the top of the water bath mesh frame 21, and positioning plates 23 are fixedly connected to both sides of the upper surface of the cover plate 22; a lifting assembly 3, which is fixedly connected to the upper surface of the positioning plates 23, and clamping components 4 for clamping and fixing a condenser 6 are arranged in a horizontal array at the lifting end of the lifting assembly 3; a circulating cooler 7, whose inlet and outlet water ends are respectively connected to the first and second boxes of the circulating water tank 13; and equipment cavities are provided at the bottom of both sides of the circulating water tank 13. The internal cavity is connected to a circulating water pump 14, and the outlet end of the circulating water pump 14 is connected to a first water pipe 15. The return end of the circulating water tank 13 is connected to a second water pipe 16. Through the configuration of the circulating water tank 13, the cooling water source for the condenser 6 can be circulated and supplied in cooperation with the circulating water pump 14, the first water pipe 15, and the second water pipe 16, thereby reducing water waste. At the same time, with the cooperation of the circulating cooler 7, the coolant flowing back into the circulating water tank 13 is rapidly cooled to ensure its efficient cooling. In addition, the device can more conveniently clamp and fix the condenser 6 through the cooperation of the lifting component 3 and the clamping component 4. Its adjustable structure further improves its clamping adaptability and meets the clamping and installation of condensers 6 of different heights and diameters. A temperature sensor is installed inside the water bath 11 to accurately control the internal temperature of the water bath 11, ensuring that the extracted components are not easily lost.

[0019] Furthermore, the liquid extraction end of the circulating water pump 14 extends into the interior of the circulating water tank 13. Above the first water pipe 15 and the second water pipe 16, an array of integrally formed diversion pipes are arranged. The first water pipe 15 is connected to the coolant supply end of the condenser 6 via the diversion pipe, and the second water pipe 16 is connected to the coolant outlet of the condenser 6 via the diversion pipe. The circulating water tank 13 is divided into a first chamber and a second chamber. The condensate collected through the second water pipe 16 first enters the first chamber of the circulating water tank 13 and then enters the circulating cooler 7 for cooling. After cooling, it enters the second chamber of the circulating water tank 13, where the circulating water pump 14 extracts the coolant from the second chamber and diverts it to the interior of the condenser 6 via the first water pipe 15.

[0020] Furthermore, the lifting assembly 3 includes a column 31, and an electric push rod 32 is fixedly connected inside the column 31. A crossbar 33 is fixedly connected to the lifting end of the electric push rod 32, and a partition 34 is fixedly connected to the inner wall of the crossbar 33. Limiting grooves 35 are provided on both the front and rear sides of the crossbar 33. By lifting the electric push rod 32, the crossbar 33 can be adjusted up and down, which in turn can adjust the clamping assembly 4 inside the crossbar 33 up and down, so that the device can be adapted to clamp and fix condensers 6 of different heights.

[0021] Furthermore, the clamping assembly 4 includes a gear 41, with racks 42 meshing on both the upper and lower sides of the gear 41. Each rack 42 has a guide rod 43 fixedly connected to its end, and a clamping plate 44 is fixedly connected to the side of the guide rods 43 that are close to each other. A support shaft is rotatably connected to the center of the gear 41, and the support shaft is fixedly connected to the outer wall of the partition 34. Rubber pads are wrapped around the sides of the guide rods 43 and the limiting groove 35 that are in contact with each other. The limiting groove 35 has a damped sliding connection to the guide rods 43. The guide rods 43 have an I-shaped structure corresponding to the limiting groove 35, and the I-shaped structure is slidably connected to the limiting groove 35. The clamping plate 44 is... The V-shaped structure, with anti-slip pads on the inner walls of the clamping plates 44 on the sides that are close to each other, allows for clamping and positioning of the condenser 6. First, one guide rod 43 is pulled outward to widen the distance between the guide rods 43, further positioning the condenser 6. Simultaneously, the guide rods 43 are moved, causing them to move closer together under the synchronous transmission of the rack 42 and gear 41, thus completing the clamping and positioning of the condenser 6. The damped sliding connection between the guide rods 43 and the limiting groove 35 provides a good damping effect, preventing the clamping plates 44 from slipping during clamping.

[0022] Working principle: First, beaker 5 is placed. Then, according to the specifications of condenser 6, the clamping height of clamping component 4 is adjusted. Then, condenser 6 is clamped and fixed by clamping component 4, while ensuring that beaker 5 and condenser 6 are connected. Then, hoses are installed on the condensate inlet and outlet of condenser 6, and the hoses are installed at the first water pipe 15 and the second water pipe 16 respectively. When the water source inside water bath 11 heats beaker 5, the sample inside beaker 5 can be clamped and refluxed for extraction.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
