Description

Technical Field

[0001] This utility model relates to the technical field of mercaptopropyltrimethoxysilane displacement extraction, and in particular to a mercaptopropyltrimethoxysilane complexation displacement extraction device. Background Technology

[0002] In the preparation process of mercaptopropyltrimethoxysilane, a large rotating disc extraction column is a key piece of equipment for achieving liquid-liquid extraction mass transfer. Its core component is a high-speed rotating shaft that runs through the column body, with multiple rotating discs fixed on the shaft. Under ideal operating conditions, the shaft should rotate precisely along the centerline of the column body. However, in actual use, due to the long length of the shaft in the large rotating disc extraction column, the long and thin shaft will undergo elastic bending deformation under the action of its own gravity, fluid impact force, and unbalanced centrifugal force. This deformation causes the instantaneous geometric centerline of the shaft to deviate from the ideal centerline during rotation, forming a dynamic radial offset.

[0003] During long-term use, radial offset or oscillation of the shaft accelerates the wear of key components such as bearings, shaft seals, and tower internals. This will eventually manifest as serious adverse phenomena such as increased vibration, component failure, media leakage, decreased mass transfer efficiency, and unexpected shutdowns, directly threatening the safety, efficiency, and stability of chemical production. Utility Model Content

[0004] This invention proposes a mercaptopropyltrimethoxysilane complexation displacement extraction device to solve the aforementioned problems.

[0005] To achieve the above objectives, this application proposes a mercaptopropyltrimethoxysilane complexation displacement extraction apparatus, comprising: tower body; The motor is installed at the top of the tower; A stirring shaft connected to the motor and arranged along the axial direction of the tower body; The stirring shaft includes: an active stirring shaft arranged axially inside the tower body and connected to the output end of the motor; a driven stirring shaft connected to the output end of the active stirring shaft and extending to the bottom of the tower body; and a universal joint connecting the output end of the active stirring shaft and the input end of the driven stirring shaft.

[0006] The present application discloses a mercaptopropyltrimethoxysilane complexation displacement extraction device, which divides the stirring shaft into an active stirring shaft and a driven stirring shaft, and connects them through a universal joint. During the operation of the extraction tower, the shaft sections can be connected at different angles, effectively compensating for axial offset and angular deviation, thereby reducing the additional radial load and stress concentration caused by misalignment, and avoiding excessive contact stress and fatigue wear on components such as bearings and seals.

[0007] Furthermore, in order to achieve a universal connection between the active stirring shaft and the driven stirring shaft section, the universal connection part includes: a ball head disposed at the input end of the driven stirring shaft; and a ball socket disposed at the output end of the active stirring shaft and covering the ball head.

[0009] Furthermore, to prevent rigid contact and jamming between the ball head and the ball socket during slight deflection, a rotation gap of 2-3 mm is provided between the end face of the ball socket and the end face of the limiting plate.

[0010] Furthermore, in order to wrap the rotating joint with an elastic pleated structure and isolate the corrosive medium inside the tower while compensating for shaft deflection, a connecting plate is provided on the side wall of the active stirring shaft near the output end, which is symmetrically arranged with the limiting plate, and an annular corrugated pipe is provided between the limiting plate and the connecting plate.

[0011] Furthermore, in order to reduce the installation difficulty between the active stirring shaft and the motor output end, the end of the active stirring shaft is connected to the motor output end via a universal joint.

[0012] Furthermore, in order to reduce the installation difficulty between the driven stirring shaft and the bottom surface of the tower body, the end face of the driven stirring shaft is connected to the bottom surface of the tower body through a universal joint.

[0013] The beneficial effects of this application are as follows: 1. The present application discloses a mercaptopropyltrimethoxysilane complex displacement extraction device, which divides the stirring shaft into an active stirring shaft and a driven stirring shaft, and connects them through a universal joint. During the operation of the extraction tower, the shaft sections can be connected at different angles, effectively compensating for axial offset and angular deviation, thereby reducing the additional radial load and stress concentration caused by misalignment, and avoiding excessive contact stress and fatigue wear on components such as bearings and seals.

[0014] 2. This application uses an annular corrugated pipe to compensate for shaft deflection while isolating corrosive media inside the tower, thereby enhancing the corrosion resistance of the universal joint.

[0015] 3. The end of the active stirring shaft of this application is connected to the output end of the motor through a universal joint, and the end face of the driven stirring shaft is connected to the bottom surface of the tower body through a universal joint, which reduces the alignment requirements of the shaft during installation, thereby reducing the installation difficulty and improving the convenience of maintenance.

[0019] The following will be combined with the appendix Figures 1-3 The embodiments of the technical solutions of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other. Specific implementation method one: like Figures 1-3 This application illustrates a mercaptopropyltrimethoxysilane complex displacement extraction device. In order to compensate for the axial offset and angular deviation between the active stirring shaft 31 and the driven stirring shaft 32 when the extraction tower is working, this application provides a universal joint 33 to connect the active stirring shaft 31 and the driven stirring shaft 32.

[0021] Specifically, an axial stirring shaft 3 is installed inside the tower body 1. This stirring shaft 3 is composed of an active stirring shaft 31 and a driven stirring shaft 32 connected by a universal joint 33. The upper end of the active stirring shaft 31 is connected to the output end of the motor 2 via a universal joint, and the lower end is connected to the upper end of the driven stirring shaft 32 via the universal joint 33. The lower end of the driven stirring shaft 32 is connected to the bottom surface of the tower body 1 via a universal joint. The universal joint 33 includes a limiting plate 331 provided on the end face of the input end of the driven stirring shaft 32. A ball head 332 is fixed on the end face of the limiting plate 331, and a ball socket 333 covering the ball head 332 is provided at the output end of the active stirring shaft 31. During the extraction operation, the motor 2 drives the active stirring shaft 31 to rotate. Through the spherical cooperation between the ball head 332 and the ball socket 333, the driven stirring shaft 32 is allowed to deflect at multiple angles within a 2-3mm rotation gap. This effectively compensates for the dynamic offset of the axis caused by the large length-to-diameter ratio of the tower body 1, avoids stress concentration caused by traditional rigid connections, and reduces fatigue wear of components such as bearings and seals. Specific Implementation Method Two: like Figures 1-3 This illustration depicts a mercaptopropyltrimethoxysilane complexation displacement extraction apparatus. To achieve a sealed and isolated universal joint 33, a connecting plate 311 is symmetrically arranged on the side wall of the active stirring shaft 31 near the output end. An annular bellows 34 is fitted between the connecting plate 311 and the limiting plate 331 of the universal joint 33. The annular bellows 34 is made of corrosion-resistant material, and its elastic corrugated structure deforms dynamically when the shaft deflects, always maintaining a sealed enclosure of the gap between the limiting plate 331 and the connecting plate 311. When a corrosive medium containing mercaptopropyltrimethoxysilane attempts to enter the universal joint 33 within the tower body 1, the annular bellows 34 forms a physical barrier through its continuous sealing surface, effectively blocking the medium intrusion path, preventing corrosion of the contact surface between the ball head 332 and the ball socket 333, extending the service life of the universal joint 33, and maintaining its rotational flexibility. Specific implementation method three: like Figures 1-3 This illustration depicts a mercaptopropyltrimethoxysilane complexation displacement extraction apparatus according to this application. To reduce the difficulty of shaft installation, the upper end of the active stirring shaft 31 is connected to the output end of the motor 2 via a universal joint, and the lower end of the driven stirring shaft 32 is connected to the bottom surface of the tower body 1 via a universal joint. Both universal joints adopt a standard component structure, allowing for a certain angular deviation of the shaft axis during installation.

[0024] As a preferred embodiment, during the assembly process, the output shaft of motor 2 and the upper end of the active stirring shaft 31 are non-rigidly aligned via a universal joint cross-shaped structure, while the lower end of the driven stirring shaft 32 and the bottom surface of the tower body 1 are also angularly compensated via a universal joint. This design reduces the stringent requirements for shaft coaxiality in traditional rigid connections, decreases the precision adjustment procedures during assembly, improves the convenience of component replacement during maintenance, and ensures the stability of power transmission at each connection point during rotation.
