[0023] like Figure 1As shown in the figure, a reaction vessel with material stirring includes a vessel body 1 and an end cover 2 mounted thereon. A stirring rod 3 is slidably mounted on the end cover 2, with one end of the stirring rod 3 extending out of the end cover 2. A driven wheel 4 is fitted onto the end of the stirring rod 3 extending out of the end cover 2. A groove 7 is formed on the outer wall of the stirring rod 3 along its length. A slider 8 is provided on the inner wall of the driven wheel 4 and is slidably connected to the groove 7. A motor 5 is mounted on the upper side of the end cover 2. The output shaft of the motor 5 is fitted with a driving wheel 6 that meshes with the driven wheel 4. By starting the motor 5 to rotate forward, the driving wheel 6 can be rotated to mesh with the driven wheel 4, thereby driving the stirring rod 3 to rotate around its own central axis. The stirring rod 3 located inside the vessel body 1 can perform stirring operations. In this embodiment, auxiliary components are provided. The left and right sides of the outer wall of the stirring rod 3 are provided with inner grooves (not shown in the attached figure) along its length direction. The auxiliary components include an auxiliary rod 23 and a limiting rod 25 rotatably connected to one end of the auxiliary rod 23. The end of the auxiliary rod 23 away from the limiting rod 25 is connected to the inner groove through a movable rod 24. The end of the limiting rod 25 not connected to the auxiliary rod 23 is rotatably connected to the inner groove of the stirring rod 3. A movable groove 26 is provided in the inner groove of the stirring rod 3 along its length direction. The end of the movable rod 24 away from the auxiliary rod 23 is slidably connected to the movable groove 26. The ends of the auxiliary rod 23 and the movable rod 24 are rotatably connected. Several sets of auxiliary components are provided and are arranged sequentially on the left and right sides of the stirring rod 3 along its length direction.

[0024] A slot 27 communicating with the inner groove is provided on the upper side of the stirring rod 3. A U-shaped linkage plate 28 is slidably arranged at the slot 27. The left and right ends of the linkage plate 28 are respectively located in the inner grooves on both sides of the stirring rod 3. The left and right ends of the linkage plate 28 are respectively connected to the respective movable rods 24 located on the same side of the stirring rod 3. An L-shaped bracket 9 is vertically slidable on the left outer wall of the vessel body 1. The upper end of the L-shaped bracket 9 is located above the end cover 2, and a motor 10 is fixed in the middle. The output shaft of the motor 10 passes through the L-shaped bracket 9 and is fitted with a rectangular driving plate 11. The right end of the driving plate 11 is located directly above the end cover 2. Arc-shaped fixing plates 15 are arranged opposite each other on the lower left and right sides of the driving plate 11. Arc-shaped movable plates 16 are opposite each other between the two sets of fixing plates 15. The upper side of the movable plate 16 is slidably connected to the lower side of the driving plate 11. A motor 17 is installed on the front outer wall of the drive plate 11. The output shaft of the motor 17 is fitted with a gear 18. A connecting plate 19 is installed on the side of the two sets of movable plates 16 that are close to each other. The ends of the two sets of connecting plates 19 are arranged vertically opposite each other. A rack 20 that meshes with the gear 18 is installed on the side facing the gear 18. The purpose is to clamp and fix the upper end of the stirring rod 3. A cylinder 30 is installed on the upper side of the L-shaped bracket 9. The bottom end of the piston rod of the cylinder 30 passes through the L-shaped bracket 9 and a push plate 31 is installed. An opening 29 for the push plate 31 to pass through is started on the upper side of the drive plate 11. At the same time, a telescopic spring 32 connected to the bottom side of the slot 27 is installed on the lower side of the linkage plate 28 located at the slot 27. The purpose is to automatically reset the linkage plate 28 after it is driven.

[0025] In this embodiment, the linkage plate 28 is provided with notches at intervals. The notches are the connection points between the limiting rod 25 and the inner groove of the stirring rod 3. The purpose is that when the linkage plate 28 drives the sets of movable rods 24 on the same side to move up and down, it will not interfere with the connection points between the limiting rod 25 and the inner groove of the stirring rod 3. A slot 22 is provided on the upper outer wall of the stirring rod 3. The inner wall of the movable plate 16 is provided with a plug block 21 that is inserted into the slot 22. The purpose is to ensure that the inner wall of the movable plate 16 can be stably connected to the stirring rod 3 when it is attached to the upper outer wall of the stirring rod 3.

[0026] A motor 312 is installed on the left side of the outer wall of the vessel body 1. A gear 13 is sleeved on the output shaft of the motor 312. An L-shaped bracket 9 is located at one end of the left side of the vessel body 1 and a rack 14 that meshes with the gear 13 is installed along the height direction of the vessel body 1.

[0027] When personnel do not need to replace the stirring rod 3, the two sets of movable plates 16 are in the closest state, and a set of cylinders 30 located on the end cover 2 are in the extended state. The push plate 31 at the piston rod of the cylinder 30 passes through the opening 29 and presses down on the linkage plate 28. Since the position of the limiting rod 25 and the inner groove of the stirring rod 3 are fixed, the connection between the auxiliary rod 23 and the limiting rod 25 will move out of the inner groove of the stirring rod 3 for stirring the material in the vessel 1. The motor 5 drives the drive wheel 6, and the drive wheel 6 drives the driven wheel 4 to drive the stirring rod 3 to rotate around its own central rod axis.

[0028] When personnel need to replace the stirring rod 3, first place the new stirring rod 3 on the left end of the L-shaped bracket 9 on the outer wall of the vessel body 1. Then, control the motor 17 to reverse, driving the gear 18 to reverse. The two sets of connecting plates 19 begin to move away from each other, and the two sets of movable plates 16 are indirectly driven, each fitting against the upper outer wall of the two sets of stirring rods 3. It should be noted that the slot 22 on the stirring rod 3 needs to be aligned with the insert 21 on the movable plate 16. The stirring rod 3 located at the end cover 2 is adjusted by the motor 5, and the stirring rod 3 located at the L-shaped bracket 9 is adjusted by personnel rotation. After the insertion is completed, the cylinder 30 begins to retract, the telescopic spring 32 returns to its original position, driving the linkage plate 28. The linkage plate 28 begins to pull the movable rod 24 in the movable position. The stirring rod slides upward within the moving groove 26. During this upward movement, the auxiliary rod 23 is driven synchronously until it is parallel to the limit rod 25. Then, the operator starts the motor 12 in the forward direction. The gear 13 engages with the rack 14, driving the L-shaped bracket 9 upward. This indirectly drives the stirring rod 3 at the end cover 2 and the stirring rod 3 on the L-shaped bracket 9 to move upward synchronously. When the stirring rod 3 is positioned above the end cover 2, the control system controls the motor 10 to rotate in the forward direction, allowing the two sets of stirring rods 3 to switch positions. Then, the motor 12 starts to rotate in the reverse direction, and the L-shaped bracket 9 moves downward, allowing the lower end of the new stirring rod 3 to enter the vessel 1 through the end cover 2, completing the replacement of the stirring rod 3. This eliminates the need to disassemble the end cover 2, reducing the workload of manual replacement.

[0029] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
