Description

Technical Field

[0001] This utility model relates to the field of fluid extraction technology, and in particular to a pressurized fluid extraction apparatus. Background Technology

[0002] Pressurized fluid extraction (PFE) is an important instrument for sample pretreatment under high temperature and pressure conditions, widely used in environmental monitoring, food safety, pharmaceuticals, and materials science. PFE can extract target compounds from solid or semi-solid samples in a short time, offering advantages such as high extraction efficiency, fast speed, and low solvent consumption.

[0003] In the internal structure of the pressurized fluid extractor, the collection bottle is placed in the collection bottle holder. Multiple placement holes are provided on the surface of the collection bottle holder to store the collection bottle, and the solvent that has been extracted can be collected in a timely manner through the collection bottle.

[0004] However, impurities can easily remain inside the placement holes due to solvent splashing and extract dripping. Although a typical collection bottle holder is easy to remove from the machine and clean the placement holes inside the holder separately, the large number of placement holes on the surface of the collection bottle holder makes it inconvenient to clean the bottom of the placement holes, resulting in a heavy cleaning burden and extended waiting time. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in cleaning the bottom of the placement hole, and to propose a pressurized fluid extraction instrument.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The design includes a pressurized fluid extraction instrument, comprising a body, a fixed base fixedly mounted on the bottom of one side of the body, a base plate fixedly mounted on the upper surface of the fixed base, a limiting protrusion fixedly mounted on the inner side of the base plate, a sliding plate provided on the inner side of the base plate, grooves formed on both sides of the sliding plate, the limiting protrusion slidably disposed in the grooves, a container rack fixedly mounted on the upper surface of the sliding plate, a rotating groove formed on the inner side of the container rack, a bottle plate rotatably disposed inside the rotating groove, and a placement hole formed inside the bottle plate.

[0007] Preferably, the upper surface of the fixed base is provided with a receiving groove, the receiving groove is located inside the base plate, and a rotating wheel is rotatably arranged inside the receiving groove.

[0008] Preferably, the axial direction of the wheel is perpendicular to the length direction of the sliding plate.

[0009] Preferably, the length direction of the sliding plate is parallel to the length direction of the limiting protrusion.

[0010] Preferably, a magnet is fixedly installed on the inner wall surface of the base plate that is in contact with the sliding plate.

[0011] Preferably, the central axis of the container rack coincides with the central axis of the bottle plate, and the placement holes are provided in a plurality of them and are arranged in a circular array around the central axis of the bottle plate.

[0012] Preferably, an insulation layer is fixedly installed on the inner wall surface of the container rack.

[0013] Preferably, a protective layer is fixedly installed on the bottom surface of the insulation layer.

[0014] The pressurized fluid extractor proposed in this utility model has the following advantages: When in use, the sliding plate can easily enter the inner side of the base plate through the cooperation of the groove and the limiting protrusion, which facilitates the disassembly and assembly of the container rack. When the sliding plate is pushed to move, the rotating wheel provides support for the sliding plate, reducing frictional resistance and making it more labor-saving. After the machine completes the extraction, the solvent can be directly injected into the collection bottle. Pulling the container rack outward makes it easy to pick up the collection bottle, reducing the probability of damage to the collection bottle. At the same time, the upper part of the container rack can be unscrewed to facilitate cleaning of the container plate and the inside of the container rack. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Refer to Figure 1-5 The pressurized fluid extraction apparatus includes a body 1. A fixed base 2 is fixedly installed on the bottom side of the body 1. A base plate 3 is fixedly installed on the upper surface of the fixed base 2. A limiting strip 4 is fixedly installed on the inner side of the base plate 3. A sliding plate 5 is provided on the inner side of the base plate 3. The length direction of the sliding plate 5 is parallel to the length direction of the limiting strip 4. Grooves 6 are opened on both sides of the sliding plate 5. The limiting strip 4 is slidably disposed in the grooves 6. A container rack 9 is fixedly installed on the upper surface of the sliding plate 5. The container rack 9 is used to store a collection bottle for collecting the extracted solvent. Pushing the container rack 9 can move the sliding plate 5. The sliding plate 5 slides along the length direction of the limiting strip 4 through the grooves 6, which facilitates the installation of the container rack 9 into the inner side of the base plate 3 and also facilitates the removal of the container rack 9 from the inner side of the base plate 3.

[0019] The container rack 9 has a rotating groove 10 on its inner side, and a bottle-holding plate 11 is rotatably mounted inside the rotating groove 10. The central axis of the container rack 9 coincides with the central axis of the bottle-holding plate 11, allowing the bottle-holding plate 11 to rotate within the rotating groove 10. Users wearing gloves can easily rotate the bottle-holding plate 11 by inserting their fingers into the placement holes 12; alternatively, they can directly rotate the collection bottle, place it in the placement hole 12, and the rotation of the collection bottle will rotate the bottle-holding plate 11. Alternatively, a handle can be provided on the surface of the bottle-holding plate 11 for easy rotation. The bottle-holding plate 11 has multiple placement holes 12 arranged in a circular array around its central axis, used to hold collection bottles. The placement holes 12 have different diameters to accommodate collection bottles of different sizes.

[0020] Furthermore, as shown in the attached diagram, the container rack 9 consists of upper and lower parts connected by threads. A groove 10 is precisely located inside the upper part of the container rack 9. When the upper and lower parts of the container rack 9 are threaded together, the space in the groove 10 is perfectly suited to accommodate the container plate 11, and the container plate 11 can rotate freely within the groove 10. After the container rack 9 is removed, its upper part can be detached, facilitating the removal of the container plate 11. This allows for thorough cleaning of the interior of both the container rack 9 and the container plate 11, preventing impurities from contaminating subsequent batches of extraction. Compared to the placement holes in existing bases, the placement hole for the container plate 11 is vertically continuous, eliminating the problem of difficult cleaning at the bottom. Cleaning is more convenient, and the entire unit can be disassembled for cleaning, resulting in high cleaning efficiency.

[0021] The upper surface of the fixed base 2 is provided with a receiving groove 7, which is located inside the base plate 3. A rotating wheel 8 is rotatably arranged inside the receiving groove 7. The axial direction of the rotating wheel 8 is perpendicular to the length direction of the sliding plate 5. The top of the rotating wheel 8 is in contact with the bottom of the sliding plate 5. The sliding plate 5 is supported by the rotating wheel 8, which can reduce the pressure of the sliding plate 5's own weight on the limiting protrusion 4, reduce the resistance between the limiting protrusion 4 and the sliding plate 5, and thus improve the smoothness of the sliding plate 5 during the sliding process.

[0022] A magnet 15 is fixedly installed on the inner wall surface of the base plate 3, which is in contact with the sliding plate 5. When the sliding plate 5 is fully pushed into the inner side of the base plate 3, the magnet 15 can attract and fix the sliding plate 5 to the inner side of the base plate 3, preventing the sliding plate 5 from slipping out of the inner side of the base plate 3 and improving the overall stability of the container rack 9. Furthermore, the use of magnetic attraction greatly improves the ease of assembly and disassembly.

[0023] Working principle: When using this pressurized fluid extractor, the collection bottle is placed in the placement hole 12. By matching the groove 6 with the limiting protrusion 4, the sliding plate 5 can enter the inner side of the base plate 3. During the movement of the sliding plate 5, the rotating wheel 8 provides support for the sliding plate 5, which can reduce the resistance between the limiting protrusion 4 and the sliding plate 5. Continue to push the sliding plate 5 and fix it to the base plate 3 through the magnetic block 15, thus completing the installation of the container rack 9. After the machine body 1 completes the extraction of the solvent, the solvent is injected into the collection bottle to complete the collection of the solvent. When the collection bottle is removed later, the container rack 9 can be pulled out. By rotating and removing the upper part of the container rack 9, it is easy to remove the container plate 11 for thorough cleaning.

[0024] Example 2: In Example 1, the extracted solution needs to be stored in a collection bottle for a period of time before subsequent analysis. During this period, some solvents require short-term insulation. Therefore, this example is proposed. (Refer to...) Figure 1 In another preferred embodiment of this utility model, based on embodiment 1, a heat insulation layer 13 is fixedly installed on the inner wall surface of the container rack 9, and a protective layer 14 is fixedly installed on the bottom surface of the heat insulation layer 13. The heat insulation layer 13 is made of ceramic cotton structure, which can have excellent heat insulation effect. The protective layer 14 is made of sponge structure and is relatively thin, which can protect the bottom of the collection bottle without affecting the heat insulation effect of the heat insulation layer 13.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
