Description

Technical Field

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

[0002] Extraction equipment is a type of mass transfer device used in extraction operations, which can achieve complete separation of the components contained in the feed liquid.

[0003] Extraction equipment is connected to infusion lines, and in actual use, insufficient sealing often occurs. Insufficient sealing is one of the common faults of existing extraction equipment, usually caused by aging, failure, or damage of sealing gaskets. Poor sealing can lead to problems such as solution leakage and solvent evaporation. When such problems occur, it is necessary for staff to disassemble the connecting pipe for maintenance and replace the sealing gaskets. However, the infusion pipes of existing equipment are fixed by multiple bolts, which is relatively laborious to disassemble and is not conducive to long-term maintenance of the extraction equipment, making it quite inconvenient.

[0004] Therefore, we propose a chemical extraction and separation device. Utility Model Content

[0005] One of the technical problems this application aims to solve is that the infusion pipe of the extraction equipment is fixed by multiple bolts, which makes disassembly difficult and inconvenient for long-term maintenance of the extraction equipment.

[0006] To address the aforementioned technical problems, this application provides a chemical extraction and separation device, comprising an extraction tube body connected to a connecting pipe, a second flange at the connecting end of the connecting pipe, and multiple symmetrically distributed positioning grooves on the second flange; an infusion pipe connected to the second flange, a first flange fitting against the second flange at the end of the infusion pipe, and a fixing plate corresponding to the positioning grooves on the first flange; and a locking mechanism, wherein a pair of sleeved steel rings are mounted on the connecting pipe to limit and fix the infusion pipe.

[0007] In some embodiments, the fixing plate is provided with insertion holes.

[0008] In some embodiments, the locking mechanism further includes a support plate fixed to the sleeve steel ring by a connecting plate, a pair of bidirectional screws rotatably connected between the two support plates, and a first moving plate and a second moving plate threadedly connected to the bidirectional screws. The first moving plate and the second moving plate are symmetrically distributed and can approach each other. The opposite sides of the first moving plate and the second moving plate are provided with plug plates that can be inserted into the plug holes.

[0009] In some embodiments, the outer end of the bidirectional lead screw is provided with an operation panel.

[0010] In some embodiments, a sloping surface is provided on the plug-in plate.

[0011] In some embodiments, a plurality of positioning rods are provided between the sleeve steel ring and the support plate, the positioning rods being respectively provided corresponding to the first moving plate and the second moving plate, and the positioning rods being slidably connected to the first moving plate and the second moving plate.

[0012] In some embodiments, an anti-slip rubber strip is provided on the inner wall of the sleeve steel ring.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By setting up No. 1 flange, No. 2 flange, fixing plate, plug plate and locking mechanism, the pipeline is freed from multiple bolts for fixing and disassembly by using tools to tighten multiple bolts one by one. This reduces manpower consumption, reduces workload, facilitates quick pipeline maintenance, improves the maintenance efficiency of the extraction device pipeline, is beneficial to large factories with large workloads, and improves practicality.

[0015] 2. By setting the inclined sliding surface of the plug plate, when the plug plate is inserted into the plug hole, the fixed plate can be gradually pushed by the continuous downward movement of the plug plate and the inclined sliding characteristic of the inclined sliding surface, which forces the infusion tube to be squeezed on the connecting tube, thereby making the internal sealing gasket more compressed, thus improving the sealing performance.

[0022] 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.

[0023] Example 1:

[0024] Please see Figures 1 to 4 The technical solution provided by this utility model is as follows: A chemical extraction and separation device includes an extraction tube body 1, a connecting tube 2 connected to the extraction tube body 1, a second flange 6 provided at the connecting end of the connecting tube 2, and a plurality of symmetrically distributed positioning grooves 15 provided on the second flange 6; an infusion tube 3 connected to the second flange 6, a first flange 5 provided at the end of the infusion tube 3 that fits against the second flange 6, a fixing plate 7 corresponding to the positioning grooves 15 provided on the first flange 5, and an insertion hole 16 provided on the fixing plate 7; it also includes a locking mechanism 4, which is set on the connecting tube 2 by a pair of sleeved steel rings 8 in the locking mechanism 4 for limiting and fixing the infusion tube 3. During installation, the pair of sleeved steel rings 8 are sleeved on the connecting tube 2 and fixed with bolts.

[0025] In this embodiment, as Figure 3 and Figure 4 As shown, the locking mechanism 4 also includes a support plate 9 fixed to the sleeve steel ring 8 by a connecting plate. A pair of bidirectional screw rods 10 are rotatably connected between the two support plates 9. An operating plate 12 is provided at the outer end of the bidirectional screw rod 10. A first moving plate 11 and a second moving plate 14 are threadedly connected to the bidirectional screw rod 10. The first moving plate 11 and the second moving plate 14 are symmetrically distributed and can approach each other. The opposite sides of the first moving plate 11 and the second moving plate 14 are provided with a plug plate 13 that can be inserted into the plug hole 16.

[0026] In this embodiment, as Figure 3 and Figure 4As shown, during installation, while flange 5 and flange 6 are fitted together, fixing plates 7 are inserted into positioning slots 15. At this time, insertion plates 13 are aligned with insertion holes 16. Rotating the operating disc 12 counterclockwise, the threads of moving plates 11 and 14 are opposite to those of the double-acting screw 10, allowing them to approach each other until insertion plates 13 are tightly inserted into insertion holes 16. This completes the process. The operation is simple, eliminating the need to use tools to tighten multiple bolts one by one, reducing labor costs, facilitating rapid pipeline maintenance, improving the maintenance efficiency of extraction device pipelines, and is beneficial for large factories with heavy workloads, thus enhancing practicality.

[0027] In this embodiment, as Figure 3 and Figure 4 As shown, a sloping sliding surface 17 is provided on the plug plate 13. When the plug plate 13 is inserted into the plug hole 16, the fixed plate 7 can be gradually pushed by the continuous downward movement of the plug plate 13 and the sloping sliding characteristic of the sloping sliding surface 17, which forces the infusion tube 3 to be squeezed on the connecting tube 2, thereby making the internal sealing gasket more compressed and thus improving the sealing performance.

[0028] In this embodiment, as Figure 3 and Figure 4 As shown, multiple positioning rods 18 are provided between the sleeve steel ring 8 and the support plate 9. The positioning rods 18 are respectively provided with corresponding positions to the first moving plate 11 and the second moving plate 14. The positioning rods 18 are slidably connected to the first moving plate 11 and the second moving plate 14. The first moving plate 11 and the second moving plate 14 can move on the positioning rods 18, thereby avoiding rotation caused by the threaded connection force, achieving the function of stable displacement, and having high practicality.

[0029] The implementation principle of a chemical extraction and separation device according to an embodiment of this application is as follows: During installation, while the No. 1 flange 5 and the No. 2 flange 6 are fitted together, the fixing plates 7 are respectively inserted into the positioning grooves 15. At this time, the insertion plates 13 are respectively aligned with the insertion holes 16. The operating disc 12 is rotated counterclockwise. The No. 1 moving plate 11 and the No. 2 moving plate 14 are connected to the bidirectional lead screw 10 in opposite directions, so that they can be brought closer to each other until the insertion plates 13 are tightly inserted into the insertion holes 16. The operation is simple, eliminating the need to use tools to tighten multiple bolts one by one, reducing labor costs, facilitating quick maintenance of pipelines, improving the maintenance efficiency of the extraction device pipelines, and is beneficial for use in large factories with large workloads, thus improving practicality.

[0030] Example 2:

[0031] Please see Figure 5 The technical solution provided by this utility model is as follows:

[0032] Unlike Embodiment 1, an anti-slip rubber strip 19 is provided on the inner wall of the sleeve steel ring 8. This arrangement can increase friction and has an anti-slip function, making the installation of the sleeve steel ring 8 more stable and improving its practicality.
