Description

Technical Field

[0001] This application belongs to the technical field of extraction and separation equipment, specifically relating to an extraction and separation device for fine chemical production. Background Technology

[0002] In the production of fine chemical products, it is often necessary to extract natural products through extraction methods, such as extracting fragrances, natural pigments, or effective components of traditional Chinese medicine from plants. This is usually done using extraction equipment.

[0003] Chinese patent publication CN222829102U discloses a low-temperature extraction device for traditional Chinese herbal plant juices. This device includes a tank with two positioning frames fixedly connected inside. An extraction tank is fixedly installed between the two positioning frames. A filter plate is fixedly connected to the bottom of the inner side of the extraction tank, and a docking groove is provided at the bottom of the extraction tank, with the top of the docking groove extending to the bottom of the filter plate. After the extraction process is completed, the material inside the extraction tank cannot be forcibly dehydrated, and the material still contains a certain amount of water. Furthermore, the concentration of extracts in this water is relatively high, requiring transfer to a separation device for solid-liquid separation. This not only increases the equipment purchase quantity and cost but also increases the plant area occupied, reducing the economic value per unit area of ​​the plant. Simultaneously, the material is easily contaminated during transfer, rendering the separated liquid unusable. Utility Model Content

Detailed Implementation

[0036] The attached figure shows the preferred embodiment of an extraction and separation device for fine chemical production. The following is a more detailed description of this application in conjunction with the attached figure.

[0037] Depend on Figures 1 to 7As shown, an extraction and separation device for fine chemical production includes a tank body 1. The top of the tank body 1 is provided with a material inlet / outlet and a drive device 5. A removable cover plate 4 is provided on the material inlet / outlet, and the drive device 5 is an electric motor. A drain pipe 3 is connected to the bottom of the tank body 1, and an electric shut-off valve is connected in series on the drain pipe 3.

[0038] The tank body 1 is equipped with a rotating rod 7 coaxially inside, and a material placement assembly 8 is connected to the rotating rod 7. The driving device 5 drives the rotating rod 7 to rotate.

[0039] Depend on Figure 4 As shown, in this embodiment, the rotating rod 7 includes a rod body 701. The top of the rod body 701 extends to the outer side of the upper part of the tank body 1 and is connected to a driven gear 702. A limiting rod 704 is coaxially connected to the lower part of the rod body 701. The limiting rod 704 drives the material placement assembly 8 to rotate, and the output end of the driving device 5 drives the driven gear 702 to rotate.

[0040] For the convenience of arranging the position of the drive device 5, the output shaft of the drive device 5 is connected to a drive gear 6, which meshes with the driven gear 702 or is connected via a transmission belt.

[0041] The horizontal cross-sectional shape of the limiting rod 704 is polygonal. Figure 5 As shown, the material placement assembly 8 includes a sleeve 801, which is sleeved on the limiting rod 704. The inner cavity shape of the sleeve 801 is the same as the horizontal cross-sectional shape of the limiting rod 704. Several material cylinders 803 are connected to the circumferential surface of the sleeve 801 through a connecting plate 802.

[0042] The material cylinder 803 has an open top and several through holes on its surface. In this embodiment, the granular solid material to be extracted is placed in a water-permeable bag, and then the bag is inserted into the material cylinder 803 through the open top. After the extraction is completed, the bag is removed from the material cylinder 803.

[0043] For ease of material handling, the material handling ports are arc-shaped, with at least two spaced-apart material handling ports located directly above the material cylinder 803 on the top surface of the tank body 1. Materials can be sequentially handled by rotating the material placement assembly 8.

[0044] To allow the material to immerse in the liquid and achieve immersion extraction, the material cylinder 803 is positioned as close as possible to the lower part of the tank 1 during the extraction operation. However, this position makes it inconvenient to load or unload the material. When loading or unloading, the material cylinder 803 should be closer to the loading / unloading port for easier operation. This necessitates that the material cylinder 803 can move vertically. To achieve this vertical movement, in this embodiment, a slide rod 703 is coaxially arranged above the driven gear 702.

[0045] The sleeve 801 is provided with several vertically arranged pull rods 805. The upper end of the pull rod 805 passes through the driven gear 702. The top of the pull rod 805 is fixed with a sliding sleeve 806, which is sleeved on the sliding rod 703.

[0046] A lifting drive assembly is fixed to the top of the tank body 1, which controls the up-and-down movement of the sliding sleeve 806. Further, the lifting drive assembly includes a vertically arranged electric linear module 10. The sliding part of the electric linear module 10 is fixed with a semi-circular retaining sleeve 9 via a connecting rod 901. The semi-circular retaining sleeve 9 is rotatably connected to the sliding sleeve 806. Specifically, the upper and lower ends of the sliding sleeve 806 are provided with limiting rings with larger outer diameters, and the semi-circular retaining sleeve 9 is engaged between the two limiting rings.

[0047] Thus, during the extraction process, the drive device 5 drives the material placement assembly 8 to rotate via the rotating rod 7, with the rotation speed controlled at 40-100 r / min. This agitates the liquid during extraction, ensuring that the content of effective components extracted from different areas of the liquid is uniform, thereby improving extraction efficiency. To enhance the turbulence effect, a baffle plate 804 protrudes from the outer circumferential surface of the material cylinder 803.

[0048] After the extraction operation is completed, the drain pipe 3 is opened and the liquid flows out. However, when the liquid level inside the tank 1 is lower than that inside the material cylinder 803, the power of the drive device 5 is increased and the rotation speed of the material placement assembly 8 is increased to more than 1000 r / min. The material inside the material cylinder 803 is spun dry by centrifugal force to achieve solid-liquid separation.

[0049] In order to support the rotating rod 7, in this embodiment, the bottom of the rotating rod 7 is inserted into the support shaft 11, and the support shaft 11 is rotatably connected to the bottom of the tank body 1.

[0050] The tank body 1 has a bearing hole at its bottom, and a support shaft 11 is connected to the bearing hole through a bearing. Several drain holes 101 are arranged in a circular array around the bearing hole. The tank body 1 has a liquid collection tank 2 at its bottom, which is located directly below the drain holes 101. The drain pipe 3 is connected to the liquid collection tank 2.

[0051] Depend on Figure 7As shown, the top surface of the support shaft 11 is recessed with an insertion hole 1101, the bottom of the limiting rod 704 is inserted into the insertion hole 1101, and a limiting plate 1102 is provided on the circumferential surface of the support shaft 11, which is placed above the bearing hole.

[0052] An electric heating device is installed inside the tank 1 to achieve high-temperature extraction.

[0053] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
