Abstract
Description

[0003] Traditional reactors have an internal rotating stirring mechanism consisting of a rotor and a stirring paddle. The stirring paddle is typically fixed to the rotor with bolts. However, this method of fixing means that the knob of the bolt is in direct contact with the solution inside the reactor. If the solution is viscous, the bolt may become stuck, and if the solution is corrosive, it may damage the bolt, affecting the connection between the stirring paddle and the rotor. This makes it difficult to remove the stirring paddle from the rotor. Therefore, we propose a stirring mechanism connection structure and its corresponding reactor. Utility Model Content

Detailed Implementation
[0035] 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.
[0036] This utility model provides, for example Figures 1-4The diagram shows a stirring mechanism connection structure, including a stirring mechanism, a positioning mechanism, a squeezing mechanism, a moving mechanism, and a supporting mechanism. The stirring mechanism includes a rotating rod 101 and a stirring paddle 102, with the stirring paddle 102 disposed at the end of the rotating rod 101. The positioning mechanism is disposed between the rotating rod 101 and the stirring paddle 102. The squeezing mechanism is disposed inside the rotating rod 101, the moving mechanism is disposed on the outer wall of the rotating rod 101, and the supporting mechanism is disposed on the outer wall of the rotating rod 101. Through the cooperation of the moving mechanism, the squeezing mechanism drives the positioning mechanism to work, thereby fixing the rotating rod 101 and the stirring paddle 102, allowing the stirring mechanism to perform stable mixing operations. Furthermore, the positioning mechanism is located inside the connecting cylinder 201, preventing the solution in the reaction vessel from directly contacting the positioning mechanism, thus ensuring that the stirring paddle 102 is not affected during disassembly and that the stirring paddle 102 can be disassembled stably.
[0037] The positioning mechanism includes a connecting cylinder 201 and a positioning shaft 203. The connecting cylinder 201 is fixedly connected to the middle of the stirring paddle 102. The bottom end of the rotating rod 101 is movably inserted into the inner wall of the connecting cylinder 201. The outer wall of the rotating rod 101 has symmetrically opened movable holes 202. The outer wall of the positioning shaft 203 is movably inserted into the inner wall of the movable holes 202. The inner wall of the connecting cylinder 201 has symmetrically opened positioning holes 204. The outer wall of the positioning shaft 203 is movably inserted into the inner wall of the positioning holes 204. The positioning shaft 203 is positioned through the movable holes 204. The rotating rod 101 is moved into the positioning hole 204 and fixed to the connecting cylinder 201, so that the stirring mechanism can work stably. A rubber sleeve 801 is attached to the top of the inner wall of the connecting cylinder 201 to seal the gap between the rotating rod 101 and the connecting cylinder 201, so that the solution in the reactor cannot come into contact with the positioning shaft 203. Therefore, when disassembling the stirring paddle 102, it is only necessary to separate the positioning shaft 203 from the positioning hole 204, which improves the convenience of disassembling the stirring paddle 102.
[0038] The extrusion mechanism includes an extrusion rod 302, a conical surface 303, and a hemispherical surface 304. The rotating rod 101 has a movable groove 301 inside. The outer wall of the extrusion rod 302 is movably connected to the inner wall of the movable groove 301. The conical surface 303 is located at the bottom end of the extrusion rod 302, and the hemispherical surface 304 is located at the end of the positioning shaft 203 near the extrusion rod 302. The outer wall of the positioning shaft 203 is provided with a reset mechanism. By moving the extrusion rod 302 downward, the conical surface 303 extrudes the hemispherical surface 304, which causes the positioning shaft 203 to move within the movable hole 202, allowing the positioning shaft 203 to be inserted into the positioning hole 204, thereby positioning the rotating rod 101 and the connecting cylinder 201.
[0039] The reset mechanism includes an annular groove 401, a fixed ring 402, and a compression spring 403. The annular groove 401 is formed on the outer wall of the movable hole 202. The outer wall of the fixed ring 402 is slidably connected to the inner wall of the annular groove 401. The fixed ring 402 is fixedly sleeved on the outer wall of the positioning shaft 203. The compression spring 403 is disposed between one side of the fixed ring 402 and the inner wall of the annular groove 401. The compression spring 403 is sleeved on the outer wall of the positioning shaft 203. When it is necessary to disassemble the agitator 102, it is only necessary to move the compression rod 302 upward until the compression rod 302 is no longer pressing the positioning shaft 203. At this time, under the elastic action of the compression spring 403, the compression spring 403 presses the fixed ring 402 to move, which can make the positioning shaft 203 automatically move in the opposite direction, thereby separating the positioning shaft 203 from the positioning hole 204. Then the rotating rod 101 can be pulled out from the connecting cylinder 201, completing the disassembly of the agitator 102.
[0040] The moving mechanism includes a connecting block 502 and a moving ring 503. The moving ring 503 is sleeved on the outer wall of the rotating rod 101. The connecting block 502 is symmetrically fixedly connected to the inner wall of the moving ring 503. The inner wall of the movable groove 301 is symmetrically provided with a connecting groove 501. The outer wall of the connecting block 502 is slidably connected to the inner wall of the connecting groove 501. The connecting block 502 is symmetrically fixedly connected to the outer wall of the extrusion rod 302. The movement of the moving ring 503 can drive the connecting block 502 to move, and then drive the extrusion rod 302 to move, thereby improving the convenience of operation of the extrusion mechanism.
[0041] The outer wall of the movable ring 503 has an insertion hole, and the inner wall of the insertion hole is movably connected to a fixing bolt 601. The outer wall of the rotating rod 101 has a threaded hole, and the outer wall of the fixing bolt 601 is threadedly connected to the inner wall of the threaded hole. When the movable ring 503 moves down, causing the extrusion mechanism to drive the positioning mechanism to work, the connecting block 502 completely abuts against the inner wall of the connecting groove 501, the insertion hole and the threaded hole are aligned, and the fixing bolt 601 is passed through the insertion hole and screwed into the threaded hole, thus fixing the movable ring 503 on the outer wall of the rotating rod 101. This prevents the extrusion rod 302 from moving up automatically, thus preventing the positioning mechanism from unlocking automatically, thereby ensuring the stability of the positioning mechanism.
[0042] The support mechanism includes a fixture 701, with a connecting hole 702 at the top of the fixture 701. A PTFE bushing 703 is inserted inside the connecting hole 702, and the rotating rod 101 is inserted into the inner wall of the PTFE bushing 703. By supporting the rotating rod 101 with the fixture 701, the rotating rod 101 is less likely to move when it rotates at high speed, thus ensuring the stability of the stirring mechanism.
[0043] This utility model also provides a reaction vessel, including the stirring mechanism connection structure of any of the above. The reaction vessel also includes a vessel head and a vessel cylinder. The solution is stirred and mixed in the vessel cylinder. A circular groove is opened at the bottom of the vessel head. The moving mechanism is located inside the circular groove. Since the solution is inside the vessel cylinder, the solution will not come into contact with the moving mechanism, thereby preventing the solution from affecting the positioning mechanism. At the same time, a circular plate is threadedly connected in the circular groove. This circular plate can block the circular groove, so that the solution splashing during stirring will not come into contact with the moving mechanism. A temperature sensor is inserted and installed in the vessel head. The part of the temperature sensor located below the vessel head is fitted with a temperature measuring sleeve. The fixing device 701 is directly fixed to the temperature measuring sleeve, thereby ensuring the stability of the support mechanism and reducing the use of connecting parts and space occupation.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
