Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Please see Figures 1 to 6 The present invention provides a technical solution: A reactor with an integrated hanger includes a hanger assembly, a drive assembly, and a replacement assembly. The drive assembly is mounted on the hanger assembly, and the replacement assembly is located on the underside of the hanger assembly.

[0020] The hanger assembly includes a gantry frame 11, a fixed housing 12, a first motor 13, a lead screw 14, a slider 15, and a lifting frame 16. The fixed housing 12 is mounted on the gantry frame 11. The first motor 13 is mounted on the fixed housing 12 by bolts. The lead screw 14 is rotatably connected to the inner wall of the fixed housing 12 and fixedly connected to the output shaft of the first motor 13. The slider 15 is threadedly connected to the lead screw 14. The lifting frame 16 is fixedly connected to the slider 15. The hanger assembly is the mechanism that enables the overall lifting of the drive assembly. When the first motor 13 rotates, its output shaft directly drives the lead screw 14 to rotate, which in turn drives the slider 15, which is threadedly engaged with the lead screw 14, to move up and down. The lifting frame 16, which is fixedly connected to the slider 15, moves synchronously. The gantry frame 11 is the support frame. The fixed shell 12 provides support and vertical guidance for the lead screw 14. The first motor 13 is the power source, and the lifting frame 16 is the installation platform for the drive assembly.

[0021] The drive assembly is used to drive the stirring, and the drive assembly is mounted on the lifting frame 16. The drive assembly is the mechanism that performs the stirring action. It achieves docking or separation with the lower vessel 33 by raising and lowering the lifting frame 16.

[0022] The replacement components include a second support 31, an annular frame 32, a vessel body 33, casters 34, and a linear track 35. The linear track 35 is fixedly connected to the gantry frame 11 via a connecting rod. The casters 34 are installed at the bottom of the second support 31. The annular frame 32 is integrally formed on the second support 31. The vessel body 33 is set on the annular frame 32, and the casters 34 are set on the linear track 35.

[0023] The component replacement mechanism is a modular mobile platform that enables rapid loading and unloading of the vessel body 33. Manually pushed, the casters 34 mounted on the bottom of the second support 31 roll along a linear track 35 fixed to the gantry frame 11, thus moving the entire component horizontally in and out of the working position. The second support 31 is a mobile base, the ring frame 32 supports and positions the vessel body 33, which is the reaction vessel, and the casters 34 are the moving parts. The casters 34 integrate a self-locking structure, which can fix the vessel body 33 on the linear track 35. The linear track 35 provides precise movement guidance, allowing the vessel body 33 to quickly move to the center position under the drive component.

[0024] Furthermore, both the slider 15 and the lifting frame 16 are slidably connected to the fixed housing 12. The threaded pair between the slider 15 and the lead screw 14 provides the main driving force. The sliding connection between the slider 15, the lifting frame 16 and the fixed housing 12 constrains the direction of movement, ensuring that they can only move in a straight line along the guide rail of the fixed housing 12, preventing rotation or swaying during the lifting process, and ensuring smooth operation and accurate positioning.

[0025] Furthermore, an inverted trapezoidal groove is provided on the straight track 35. The wheel surface of the caster 34 cooperates with the inverted trapezoidal groove. Utilizing its structure of being wider at the bottom and narrower at the top, it can generate a downward restraining force on the caster 34, effectively preventing the caster 34 from dislodging from the track when bearing weight or subjected to slight lateral forces, greatly enhancing the stability and safety during movement and positioning.

[0026] Furthermore, a guide slope 36 is provided at one end of the linear track 35. The guide slope 36 is a gentle slope. When the vessel assembly with casters 34 is pushed from the ground onto the linear track 35, the guide slope 36 can guide the casters 34 to smoothly and effortlessly transition into the inverted trapezoidal groove of the track, eliminating the need for manual lifting and simplifying the loading operation of the vessel 33.

[0027] Furthermore, the drive assembly includes a universal joint 21, a second motor 22, a seal 23, a vessel lid 24, a stirring shaft 25, and a stirring rod 26. The universal joint 21 is mounted on the lifting frame 16. The upper end shaft of the universal joint 21 is fixedly connected to the output shaft of the second motor 22. The second motor 22 is mounted on the universal joint 21. The lower end shaft of the universal joint 21 is fixedly connected to the stirring shaft 25. The stirring rod 26 is mounted on the stirring shaft 25. The seal 23 is fixedly connected to the lifting frame 16. The vessel lid 24 is fixedly connected to the seal 23.

[0028] The second motor 22 operates, and the power is transmitted to the stirring shaft 25 through the universal joint 21, which drives the stirring shaft 25 and the stirring rod 26 on it to rotate, thereby stirring the material. The universal joint 21 is used to compensate for the slight coaxiality error that may exist between the stirring shaft 25 and the output shaft of the second motor 22. The seal 23 is a static transition piece connecting the lifting frame 16 and the stirring shaft 25, and integrates a dynamic sealing structure. The lid 24 is a component that covers the opening of the vessel body 33.

[0029] Furthermore, a rubber ring is bonded to the outer side of the vessel lid 24, and the outer side of the vessel lid 24 matches the vessel body 33. When the drive assembly descends and the vessel lid 24 is pressed into the top opening of the vessel body 33, the rubber ring bonded to the outer side of the vessel lid 24 will be squeezed and deformed against the inner wall gasket of the vessel body 33, filling all microscopic gaps, thereby forming a reliable static seal to prevent material or gas from leaking from the joint between the vessel lid 24 and the vessel body 33 during the reaction process.

[0030] Furthermore, one end of the stirring shaft 25 passes through the seal 23 and is rotatably connected within the seal 23. The stirring shaft 25 is rotatably connected within the seal 23 via a bearing, ensuring smooth rotation.

[0031] Furthermore, a second switch 41 and a first switch 42 are fixedly connected to one side of the gantry frame 11. The first switch 42 and the second switch 41 are used to control the forward and reverse rotation of the first motor 13 and the second motor 22, respectively, thereby indirectly controlling the lowering and raising actions of the drive assembly and the stirring action of the drive assembly.

[0032] The reactor 33 is made of high borosilicate glass, the second motor 22 is a 400W servo motor, the lid 24 is made of stainless steel, the bottom of the reactor body 33 is connected to a quick-opening stainless steel discharge valve, and the first motor 13 is a stepper motor.

[0033] The operating principle of this invention is as follows: During operation, the replacement assembly containing the vessel body 33 is pushed into the working position below the gantry frame 11 via the universal wheels 34 along the straight track 35. The guide slope 36 assists in positioning. The first switch 42 is operated to start the first motor 13 to rotate forward, driving the lifting frame 16 to descend via the lead screw 14, which in turn drives the entire drive assembly to descend synchronously until the vessel cover 24 is pressed into the vessel body 33 and sealed by rubber rings and gaskets. The second motor 22 is then started, and power is transmitted to the stirring rod 26 via the universal joint 21 and the stirring shaft 25 to start stirring. The stirring shaft 25 rotates within the sealing element 23, and leakage is prevented by the dynamic seal. After the operation is completed, the second motor 22 is stopped, and the second switch 41 is operated to reverse the first motor 13, raising the drive assembly. The entire vessel body 33 of the replacement assembly can be pulled out along the straight track 35, and another vessel body 33 that has been prepared can be pushed in to quickly carry out the next batch of reaction, realizing rapid material change in intermittent production, improving efficiency. The universal joint 21 compensates for centering errors, and the inverted trapezoidal groove track ensures movement stability.
