Description

Technical Field

[0001] This utility model relates to the field of extraction device technology, specifically a combined Soxhlet extraction device. Background Technology

[0002] The Soxhlet extractor is a classic solid-liquid extraction device that achieves efficient extraction of target organic compounds from solid samples through solvent reflux and siphon circulation. It consists of a closed system formed by three vertically connected parts: a heating flask, an extraction cylinder, and a condenser. The extraction cylinder contains a sample filter paper sleeve, and there are siphon tubes and connecting tubes on both sides of the extraction cylinder. It is widely used in food testing, pharmaceutical research and development, environmental analysis and other fields, and has the advantages of low solvent consumption and thorough extraction.

[0003] Existing modular Soxhlet extraction devices, due to their fixed rigid structure, have a fixed size, are difficult to transport, lack dynamic adjustment capabilities, and still occupy a dedicated area when not in operation, resulting in low space utilization. This creates a structural contradiction with the needs of modern field testing, emergency response, and other multi-scenario adaptation and rapid response, and cannot meet emerging needs such as emergency testing and mobile office. Utility Model Content

[0004] The purpose of this invention is to provide a combined Soxhlet extraction device to solve the problem that existing combined Soxhlet extraction devices lack dynamic adjustment capabilities due to their fixed rigid structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A combined Soxhlet extraction device includes a base, a retractable mounting frame fixedly connected to the base, connecting rods rotatably connected to both sides of the base, two connecting rods arranged symmetrically, support feet installed at the front and rear ends of the two connecting rods, and multiple rollers arranged in an array installed at the bottom of the base.

[0007] Preferably, the fixing frame includes a telescopic rod, a support frame, and a positioning gripper. The support frame is fixedly connected to the telescopic end of the telescopic rod, and the positioning gripper is fixedly connected to the surface of the support frame.

[0008] Preferably, both sides of the base are provided with horizontally sliding fixing pins, which are used to fix the connecting rod.

[0009] Preferably, the surface of the connecting rod is provided with a first slot for inserting a fixing pin, and the surface of the connecting rod is provided with a second slot for inserting a fixing pin.

[0010] Preferably, the support foot includes a connecting block, a threaded sleeve, and a threaded rod, wherein the threaded rod and the connecting rod are fixedly connected, the threaded sleeve is threaded onto the surface of the threaded rod, and the connecting block is rotatably connected to the bottom end of the threaded sleeve.

[0011] Preferably, the bottom of the connecting block is movably connected to a support block via a ball joint.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This modular Soxhlet extraction device, through its foldable structure and dynamically adjustable components, successfully solves the problems of traditional fixed devices, such as large size, inconvenient transportation, and poor adaptability to different scenarios. The mounting frame can freely switch between extending to fix the instrument and retracting for standby, achieving volume compression during transportation. The threaded joint and ball joint work together to compensate for terrain slope, allowing deployment or storage to be completed in 3-5 minutes, significantly improving the response efficiency of emergency field detection and providing a lightweight and highly adaptable solution for multiple scenarios such as mobile detection and scientific expeditions.

[0019] 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.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a combined Soxhlet extraction device, including a base 1 and a constant temperature water bath 14. The base 1 is fixedly connected to a retractable fixing frame, which is used to fix the flask, extraction tube, and reflux condenser. Connecting rods 7 are rotatably connected to both sides of the base 1. The two connecting rods 7 are symmetrically arranged, and support feet are installed at both ends of the two connecting rods 7. Multiple rollers 2 arranged in an array are installed at the bottom of the base 1. By connecting the support feet to the connecting rods 7, the support feet can be adjusted to a vertical or horizontal state by rotating the connecting rods 7. When the support feet are in a horizontal state, the rollers 2 are grounded, which facilitates the movement of the device. When the support feet are in a vertical state, it is convenient to support the device for testing.

[0021] The fixing frame includes a telescopic rod 11, a support frame 12 and a positioning claw 13. The support frame 12 is fixedly connected to the telescopic end of the telescopic rod 11, and the positioning claw 13 is fixedly connected to the surface of the support frame 12. The positioning claw 13 can clamp and fix the flask, extraction tube and reflux condenser tube. Multiple positioning claws 13 can be set according to the number of clamping requirements.

[0022] To adapt to situations where power is scarce in the wild, the telescopic pole 11 is designed to be manually telescopic and equipped with a U-shaped pin. After the telescopic pole 11 is extended, the U-shaped pin is inserted into the telescopic joint to prevent the telescopic end from retracting.

[0023] To adapt to situations where power is scarce in the wild, the rotation of the connecting rod 7 is also manually adjustable. Both sides of the base 1 are provided with horizontally sliding fixing pins 10, which are used to fix the connecting rod 7. The surface of the connecting rod 7 is provided with a first slot 8 for the fixing pin 10 to be inserted, and when the fixing pin 10 is inserted into the first slot 8, the support foot is in a vertical state. The surface of the connecting rod 7 is provided with a second slot 9 for the fixing pin 10 to be inserted, and when the fixing pin 10 is inserted into the second slot 9, the support foot is in a horizontal state.

[0024] The support foot includes a connecting block 4, a threaded sleeve 5, and a threaded rod 6. The threaded rod 6 and the connecting rod 7 are fixedly connected. The threaded sleeve 5 is threaded onto the surface of the threaded rod 6. The connecting block 4 is rotatably connected to the bottom end of the threaded sleeve 5. By rotating the threaded sleeve 5, the threaded pair between it and the threaded rod 6 can drive the connecting block 4 and the threaded sleeve 5 to move axially synchronously, thereby adjusting the vertical height of the support system, compensating for road unevenness, and keeping the main body of the device in a horizontal state.

[0025] The bottom of the connecting block 4 is movably connected to the support block 3 via a ball joint. The ball joint can swing freely within ±30° in the X, Y, and Z axes. When the height of the connecting block 4 is adjusted by the thread, the ball joint allows the support block 3 to maintain full contact with the ground, compensating for multi-directional angular deviations caused by terrain tilt and ensuring the spatial stability of the support system.

[0026] The base 1 is fixedly connected to the bottom of the constant temperature water bath 14.

[0027] The specific solution is as follows: Manually rotate the symmetrical connecting rods 7 on both sides to rotate the support feet to a horizontal state, push the horizontally sliding fixed pin 10 to insert it into the second slot 9 positioning hole on the surface of the connecting rod 7, lock the support feet to a horizontal state, and at this time the roller 2 at the bottom of the device is grounded, which facilitates movement;

[0028] Push the device to the test area using the bottom roller 2, ensuring the ground is flat or easy to adjust the support feet. Pull out the fixing pin 10 to disengage from the second slot 9. Manually rotate the connecting rod 7 until the support foot connecting block 4 is vertically downward. Then insert the fixing pin 10 into the positioning hole of the first slot 8 on the surface of the connecting rod 7 to lock the support feet in a vertical position. Rotate the threaded sleeve 5 to drive the connecting block 4 and the threaded sleeve 5 to move axially synchronously through the threaded pair transmission, so that the ball joint support block 3 at the bottom of the connecting block 4 contacts the ground. Observe the levelness of the main body of the device. Fine-tune the height by rotating the threaded sleeve 5 to compensate for uneven terrain.

[0029] Manually stretch the telescopic rod 11 of the fixing frame to the required height, insert the U-shaped pin to fix the telescopic joint and prevent it from retracting, assemble the flask, extraction tube and reflux condenser tube in sequence, place them on the constant temperature water bath 14, and clamp and fix them with the positioning claw 13.

[0030] Add extraction solvent to the flask, load the sample to be extracted into the extraction tube, and connect the reflux condenser. Heat the flask according to the standard Soxhlet extraction procedure, control the temperature to allow the solvent to reflux, circulate the extraction sample, observe the reflux status of the condenser, and ensure that the device is well sealed.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
