Description

Technical Field

[0001] This utility model relates to the field of analytical testing technology, specifically to a small multi-tube cable extraction device. Background Technology

[0002] Soxhlet extractors are important equipment in fields such as chemical analysis and detection. They achieve continuous extraction of target components from solid samples through solvent reflux and siphon principle. However, traditional extraction devices cannot test multiple samples at the same time, and the operation of condenser tubes in series is cumbersome.

[0003] Traditional apparatuses are mostly single-unit designs, processing only one sample at a time. For batch parallel experiments, repeated operations or multiple devices operating in parallel are necessary, which is not only time-consuming but also prone to errors due to equipment differences. Furthermore, traditional electric heating mantles result in uneven heating, low efficiency, and the heating source is prone to localized overheating. The limited cooling area of ​​the condenser tube leads to excessively long "evaporation-condensation-siphon" cycles, reducing the number of extractions per unit time. They also occupy space and make it difficult to process multiple samples simultaneously. Traditional rubber tubing or simple sleeve structures are prone to wear, cumbersome to operate, and when multiple tubes are connected, individual leaks may occur, causing result deviations. The limited pressure resistance of rubber tubing also hinders simultaneous processing of multiple samples.

[0004] While existing improvements attempt to add multiple units or electronic temperature control, they fail to address core issues such as poor parallel synchronization and easy wear and tear on the sealing structure, resulting in limited efficiency gains. Furthermore, mainstream imported automated Soxhlet extraction devices are complex and have issues with plastic or metal consumables that may come into contact with the sample, potentially causing contamination, or the consumables are proprietary, cumbersome to use, and expensive to replace. Therefore, developing a device with multiple parallel units, columnar heating, and disc-shaped serpentine condensation to increase cycle time, offering convenient adjustment and efficient synergy between temperature control and condensation, using ordinary glass components, is key to overcoming the efficiency bottleneck of traditional Soxhlet extractors.

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.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0035] Example

[0036] This embodiment provides a small multi-tube cable extraction device, including: a heater 1, an extraction device 2, a condensation device 3, a temperature controller, a switching valve, and a cooling water pump;

[0037] Among them, heater 1 has a cuboid structure and has 12 equally spaced heating slots 11 inside;

[0038] An electric heating jacket is fixedly installed in the heating tank 11. The electric heating jacket is made of corrosion-resistant material and is used to uniformly heat the beaker 21 placed in it to ensure stable evaporation of the solvent in the beaker.

[0039] Several adjustable racks 12 are fixedly installed on both sides of the top of the heater 1. The condensing device 3 is placed on the adjustable racks 12. The adjustable racks 12 are used to support the condensing device 3 and flexibly adjust its height to adapt to different specifications of extraction tubes 22.

[0040] The adjustable shelf 12 includes a fixing rod 121 and a shelf body 122.

[0041] The bottom of the fixing rod 121 is vertically fixed to the top wall of the heater 1, providing stable support for the main body 122 of the placement frame;

[0042] A sliding sleeve 121c adapted to the fixed rod 121 is fixedly provided at the bottom of the main body 122 of the placement rack. The sliding sleeve 121c is sleeved on the outer surface of the fixed rod 121 and can slide along its axial direction to realize the adjustment of the height of the condensation device 3.

[0043] The fixing rod 121 has a plurality of first threaded holes 121a equidistantly opened along its height direction, and the sliding sleeve 121c has at least one second threaded hole correspondingly opened. The first threaded holes 121a and the second threaded holes are locked by screwing together with fixing bolts, which can accurately fix the position of the main body 122 of the placement frame and prevent displacement due to vibration during use.

[0044] The main body 122 of the placement rack includes: a placement base 1221 and several vertical rods 1222;

[0045] One side of the placement seat 1221 is fixedly connected to the side wall of the sliding sleeve 121c away from the fixed rod 121, providing a bearing surface for the condensation device 3;

[0046] Several vertical rods 1222 are vertically arranged at equal intervals along the outer periphery of the placement base 1221. The vertical rods 1222 can limit the side of the condensing device 3 and prevent the condensing device 3 from sliding on the placement base 1221.

[0047] A buffer pad is fixedly provided on the top of the placement seat 1221. The buffer pad is made of elastic material, which can reduce the impact damage when the condensation device 3 comes into contact with the placement seat 1221.

[0048] The extraction device 2 includes a beaker 21 and an extraction tube 22.

[0049] Beaker 21 is placed in heating tank 11 to contain extraction solvent and receive refluxed extract, facilitating subsequent collection of target components;

[0050] The bottom opening of the extraction tube 22 is sealed to the opening of the beaker 21. The side of the extraction tube 22 is connected to the steam tube 23 and the siphon tube 24 respectively. The steam tube 23 is used to introduce the solvent vapor evaporated in the beaker 21 into the condenser 3 to realize the recycling of the solvent. When the condensate in the extraction tube 22 reaches a certain height, the siphon tube 24 uses the siphon effect to return the solution mixed with the target components to the beaker 21, completing one extraction cycle.

[0051] The condensing device 3 includes: a condensing box 31, 12 connectors 32 fixedly disposed at the bottom of the condensing box 31, and 12 serpentine condensing tubes 33 fixedly disposed inside the condensing box 31.

[0052] The left and right sides of the condenser 31 are respectively connected to an inlet pipe 311 and an outlet pipe 312. The inlet pipe 311 is used to introduce cooling water, and the outlet pipe 312 is used to discharge the hot water after heat absorption, forming a continuous cooling cycle to ensure the condensation effect.

[0053] Twelve connectors 32 are equidistantly arranged at the bottom of the condensation box 31. The spacing and arrangement of each adjacent connector 32 are consistent with the spacing and arrangement of each adjacent heating tank 11, ensuring that each connector 32 can be connected to the corresponding extraction tube 22, so that the 12 extraction processes can be carried out simultaneously.

[0054] The bottom of the connector 32 is sealed to the top opening of the extraction tube 22. It can also be sealed with a high-temperature resistant sealing material to prevent leakage of liquid after condensation and reduce solvent loss.

[0055] The bottom inlet of each serpentine condenser tube 33 penetrates the bottom wall of the connector 32 and communicates with the internal environment of the extraction tube 22. The bottom of the serpentine condenser tube 33 is sealed to the bottom wall of the connector 32 to ensure that the cooling water in the condensation box 31 does not seep into the extraction tube 22 and avoids contamination of the extract.

[0056] The outlet at the top of the serpentine condenser tube 33 penetrates the top wall of the condenser box 31 and connects to the external environment to balance the gas pressure inside the condenser tube and ensure that the condensate drips smoothly.

[0057] The bottom wall of connector 32 prevents the cavity of condenser 31 from communicating with the cavity of extraction tube 22, thus isolating the cooling system and extraction system from each other and ensuring that their respective functions are not interfered with.

[0058] A temperature controller is fixedly installed on the side wall of heater 1. The temperature controller is electrically connected to the electric heating mantle. The temperature controller can accurately adjust the heating temperature of the electric heating mantle. The corresponding temperature can be set according to the boiling point of different solvents to avoid excessive temperature causing solvent decomposition or damage to the target components.

[0059] The inlet end of the water inlet pipe 311 is connected to the outlet end of the switch valve, and the inlet end of the switch valve is connected to the outlet end of the cooling water pump. The switch valve is used to control the on / off of the cooling water, and the cooling water pump provides power for the cooling water circulation, ensuring that the cooling water continuously flows through the condenser box 31 and carries away the heat of the serpentine condenser tube 33.

[0060] In a preferred embodiment, the sealing fit in this embodiment is a pipe connection with a frosted opening; the frosted opening includes an outer frosted surface and an inner frosted surface disposed at the end of the connecting component, and the two are tightly fitted to form a sealing structure.

[0061] In a preferred embodiment, the apex of the siphon tube 24 is located at 1 / 3 of the height of the extraction tube 22 to shorten the time required for a single siphon.

[0062] When using, place the sample to be extracted into the filter paper tube inside the extraction tube 22, add an appropriate amount of extraction solvent to the beaker 21, place the beaker 21 in the heating bath 11, and seal the bottom of the extraction tube 22 with the beaker 21.

[0063] By adjusting the height of the sliding sleeve 121c of the adjustable placement rack 12, the connector 32 of the condensation device 3 is sealed to the top of the extraction tube 22, and the fixing bolt is tightened to fix the position.

[0064] Connect the inlet pipe 311, the switch valve, the cooling water pump, and the outlet pipe 312 to ensure unobstructed cooling water circulation.

[0065] Turn on the temperature controller, set the appropriate heating temperature, and the electric heating mantle starts to heat the beaker 21. The vapor generated by the solvent evaporation enters the serpentine condenser 33 through the steam pipe 23.

[0066] Turn on the switch valve and cooling water pump, and cooling water enters the condenser 31, absorbing the heat of the steam in the serpentine condenser tube 33. The steam condenses into liquid and drips into the extraction tube 22, making full contact with the sample for extraction.

[0067] When the condensate in the extraction tube 22 reaches the highest point of the siphon tube 24, the liquid flows back to the beaker 21 through the siphon tube 24, completing one extraction cycle.

[0068] After repeating the above cycle several times, turn off the temperature controller, cooling water pump and switch valve, disassemble the device, and take out beaker 21 to obtain the extract.

[0069] In summary, the solenoid extraction device of this embodiment significantly improves extraction efficiency through multiple parallel structures, the adjustable rack adapts to extraction containers of different sizes, and the temperature control and efficient condensation design ensures extraction results. It is suitable for multi-batch component extraction in the food, pharmaceutical and other fields, providing an efficient and stable solution for scientific research and production.

Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of this utility model should be included within the protection scope of this utility model.
