The schematic implementation methods of the utility model and their descriptions are only used to explain the utility model and are not intended to limit the utility model.

[0026] Example

[0027] like Figures 1 to 4 As shown, the utility model includes a kettle body 1 and a kettle cover 8, and also includes a rotating component 7, the rotating component 7 is provided with a first driving mechanism 5, the movable end of the first driving mechanism 5 is connected to the kettle cover 8, the first driving mechanism 5 is used to drive the kettle cover 8 to move axially along the kettle body 1, and a plurality of second driving mechanisms 4 are also provided on the side wall of the kettle body 1, the movable end of the second driving mechanism 4 is provided with a slider 12 located in the kettle body 1, and the slider 12 is used to drive the slider 12 to move radially along the kettle body 1.

[0028] The kettle body 1 and the kettle cover 8 of the reactor in the prior art are usually connected by flange or thread. Among them, the flange connection method is relatively complicated. The flange connection requires precise alignment and uniform tightening of multiple bolts to prevent deformation caused by uneven force on the flange surface, which is time-consuming. The threaded connection method causes the threads on the kettle cover 8 and the kettle body 1 to easily cause wear after long-term use, affecting the airtightness between the kettle cover 8 and the kettle body 1. For this reason, the technical solution provides a rotating component 7, and a first driving mechanism 5 is provided on the movable end of the rotating component 7. The first driving mechanism 5 is a cylinder, and the movable end of the cylinder is connected to the top of the kettle cover 8. In this way, when working, the first driving mechanism 5 can be used to drive the kettle cover 8 to move in the vertical direction in the kettle body 1, so that the kettle cover 8 is placed in the kettle body 1; and in order to improve the stability of the kettle cover 8 in the kettle body 1 in the present technical solution, a plurality of second driving mechanisms 4 are further arranged on the side wall of the kettle body 1, and the second driving mechanism 4 is a micro cylinder, and a slider 12 is arranged on the movable end of the second driving mechanism 4. When the second driving mechanism 4 is working, it can drive the slider 12 to move radially in the kettle body 1. Therefore, when the kettle cover 8 is extended into the kettle body 1 under the action of the first driving mechanism 5, when the top of the kettle cover 8 moves to the same horizontal plane as the bottom of the slider 12, the second driving mechanism 4 drives the slider 12 to move to the top of the kettle cover 8, and the slider 12 is used to limit the top of the kettle cover 8, thereby ensuring that the kettle cover 8 will not move freely in the kettle body 1, and ensuring that the kettle cover 8 can be stably fixed in the kettle body 1.

[0029] When the reaction is completed and the kettle cover 8 needs to be removed, the second driving mechanism 4 is first used to drive the slider 12 to move back to remove the restriction on the kettle cover 8, and then the first driving mechanism 5 is used to drive the kettle cover 8 to move upward to move the kettle cover 8 located in the kettle body 1 out, and finally the rotating assembly 7 is used to drive the first driving mechanism 5 to rotate on a horizontal plane to remove the kettle cover 8 from the kettle mouth of the kettle body 1, so as to facilitate the removal of the material in the kettle body 1, thereby realizing the rapid opening of the kettle cover 8 and improving the production efficiency.

[0030] The rotating assembly 7 includes a support platform 23, a column 24, a movable cylinder 22 and a rotating arm 18. The column 24 is fixed on the support platform 23, the movable cylinder 22 is mounted on the column 24, and the movable cylinder 22 can rotate around the column 24; one end of the rotating arm 18 is connected to the side wall of the movable cylinder 22, and the other end is connected to the first driving mechanism 5.

[0031] In this embodiment, in order to ensure that the rotating assembly 7 can rotate the first driving mechanism 5 in the horizontal direction, thereby displacing the kettle cover 8 from the kettle mouth of the kettle body 1, so as to facilitate the material to be reacted to be put into the kettle body 1, or to take out the material that has completed the reaction from the kettle body 1, a movable cylinder 22 is sleeved on the column 24. Under the action of the rotating arm 18, the first driving mechanism 5 can be driven to rotate with the movable cylinder 22, thereby realizing the adjustment of the position of the first driving mechanism 5 on the horizontal plane.

[0032] The rotating assembly 7 further includes a pressing plate 20 , and the pressing plate 20 is fixed to the top of the column 24 by a first screw.

[0033] In this embodiment, since the movable cylinder 22 is sleeved on the column 24 from the top of the column 24, in order to prevent the movable cylinder 22 from falling off from the end of the column 24, a pressure plate 20 is also provided on the top of the column 24. The pressure plate 20 is fixed to the top of the column 24 by a first screw for easy loading and unloading. The diameter of the pressure plate 20 is not less than the outer diameter of the movable cylinder 22. Under the limiting action of the pressure plate 20, the movable cylinder 22 can be prevented from moving out of the column 24.

[0034] The rotating assembly 7 further includes a locking screw 21 , which is connected to the side wall of the movable cylinder 22 via a thread, and is used to fix the movable cylinder 22 on the column 24 .

[0035] In this embodiment, in order to prevent the movable cylinder 22 from rotating freely, a locking screw 21 is further provided on the movable cylinder 22. When the movable cylinder 22 needs to be rotated, the locking screw 21 is loosened so that the locking screw 21 does not contact the outer surface of the column 24, thereby allowing the movable cylinder 22 to rotate smoothly on the column 24; and when the movable cylinder 22 needs to be temporarily fixed on the column 24, the locking screw 21 is tightened so that the locking screw 21 moves to the outer wall of the column 24, and the movable cylinder 22 is temporarily fixed on the column 24 by utilizing the friction resistance between the end of the locking screw 21 and the side wall of the column 24.

[0036] A connecting seat 17 is provided on the movable end of the first driving mechanism 5; a second screw 19 is also provided on the top of the kettle cover 8, a ball seat 15 is provided on the second screw 19, a sphere is provided in the ball seat 15, the sphere is movably connected to the ball seat 15 through a pin 16, and the bottom of the connecting seat 17 is connected to the sphere.

[0037] Since the kettle cover 8 is inserted into the kettle body 1 in the vertical direction through the set first driving mechanism 5, and the kettle cover 8 can rotate around the column 24 under the action of the movable cylinder 22, when the kettle cover 8 is not aligned with the central axis of the kettle body 1 under the rotation of the movable cylinder 22, the kettle cover 8 will collide with the kettle body 1 under the action of the first driving mechanism 5, and in severe cases, it will cause damage to the kettle cover 8 or the kettle body 1. In order to prevent the above situation from occurring, this embodiment provides a connecting seat 17 between the kettle cover 8 and the movable end of the first driving mechanism 5, and the connecting seat 17 is connected to the ball on the connecting seat 17, and the set ball is connected to the ball seat 15 through the pin 16, so that the ball can rotate on the ball seat 15. Therefore, when the first driving mechanism 5 drives the kettle cover 8 to extend into the kettle body 1, even if there is a certain deviation of the kettle cover 8, under the action of the ball, the kettle cover 8 can automatically adjust the center, to ensure that the kettle cover 8 can be smoothly inserted into the kettle body 1, and avoid the kettle cover 8 and the kettle body 1 from a violent collision.

[0038] The inner wall of the kettle body 1 is provided with grooves 14 having the same number as the sliders 12 , and the sliders 12 are located in the grooves 14 ; the depth of the grooves 14 along the radial direction of the kettle body 1 is not less than the thickness of the sliders 12 along the radial direction of the kettle body 1 .

[0039] In this embodiment, in order to ensure that the kettle cover 8 can move normally in the kettle body 1 and avoid the slider 12 from obstructing the kettle cover 8, a groove 14 for accommodating the slider 12 is provided on the inner wall of the kettle body 1; at the same time, in order to ensure that the slider 12 can be fully retracted into the groove 14, the depth of the groove 14 is not less than the thickness of the slider 12.

[0040] A limiting platform 10 is further provided on the inner wall of the kettle body 1 , and a protrusion is provided on the side wall of the kettle cover 8 . The protrusion is distributed along the circumference of the kettle cover 8 , and the limiting platform 10 is used to limit the protrusion.

[0041] In this embodiment, in order to ensure that the slider 12 can limit the kettle cover 8 so that it can be stably fixed in the kettle body 1, a limiting platform 10 is also provided in the kettle body 1. When the first driving mechanism 5 drives the kettle cover 8 to extend into the kettle body 1, when the protrusion on the kettle cover 8 moves to the limiting platform 10 in the kettle body 1, the limiting platform 10 is used to limit the kettle cover 8 so that it cannot continue to move downward. At this time, the upper surface of the kettle cover 8 is just flush with the bottom of the slider 12. Therefore, the slider 12 can act on the top of the kettle cover 8 under the action of the first driving mechanism 5, and cooperate with the limiting platform 10 to stably fix the kettle cover 8 in the kettle body 1.

[0042] In order to improve the air tightness between the inner wall of the kettle body 1 and the kettle cover 8, a sealing ring is also provided on the kettle cover 8.

[0043] A first tube body 2 is disposed at the bottom of the kettle body 1 ; a second tube body 3 is also disposed on the side wall of the kettle body 1 .

[0044] The first tube body 2 is used to introduce the gas required for the reaction into the kettle body 1 ; the second tube body 3 is used to discharge the gas after the reaction in the kettle body 1 .

[0045] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model.
