[0021] Embodiment 1:

[0022] As Figure 1 shown, the present utility model provides a technical solution, a grinding device for the mouth of a reaction kettle, including a support frame 1. The bottom of the support frame 1 is welded with support feet, which play a good role in stable support. The central part of the upper surface of the support frame 1 is fixedly installed with a vertically arranged cylindrical column 2 through bolts. The top of the column 2 is provided with a lifting mechanism 3 that can rotate along the axis of the column 2. The outer wall of the middle part of the column 2 is sleeved with a kettle body lifting sliding sleeve 4. One side of the kettle body lifting sliding sleeve 4 is fixedly connected with a kettle body fixing frame 6 for installing the reaction kettle body 5 through bolts. The telescopic end of the lifting mechanism 3 is fixedly connected with one side of the kettle body fixing frame 6 through bolts, and a first driving component for driving the reaction kettle body 5 to rotate is arranged on the kettle body fixing frame 6; on one side of the top of the support frame 1, there is also a grinding disc 7, and a second driving component for driving the grinding disc 7 to rotate is arranged on the support frame 1.

[0023] The above lifting mechanism 3 can adopt a worm and screw jack, and the bottom of the main body of the lifting mechanism 3 is rotationally connected with the bearing at the top of the column 2 through a rotating shaft; the reaction kettle body 5 is rotationally connected with the kettle body fixing frame 6 through a rotating bearing, and the reaction kettle body 5 should be installed upside down on the kettle body fixing frame 6.

[0024] Embodiment 2:

[0025] As Figure 1 shown, the present utility model provides another technical solution, a grinding device for the mouth of a reaction kettle. The difference from Embodiment 1 is that the first driving component is composed of a kettle body rotating motor 8, a driving gear 9 and a kettle body rotating gear disc 10. The kettle body rotating gear disc 10 is fixedly sleeved at the mouth 11 of the reaction kettle. The kettle body rotating motor 8 is fixedly installed at the bottom of the kettle body fixing frame 6 through bolts. The output end of the kettle body rotating motor 8 is fixedly sleeved with a driving gear 9, and the driving gear 9 is meshed with the kettle body rotating gear disc 10.

[0026] As Figure 3 shown, this embodiment provides a specific structure of the driving gear 9 and the kettle body rotating gear disc 10, both of which adopt bevel gears.

[0027] Specifically, the kettle body lifting sliding sleeve 4 can move up and down along the column 2, and the kettle body lifting sliding sleeve 4 can rotate along the axis of the column 2, facilitating the movement of the reaction kettle body 5.

[0028] Embodiment 3:

[0029] As Figure 1 shown, the present utility model provides another technical solution, a reaction kettle mouth grinding device. Different from Embodiment 1, the second driving assembly consists of a grinding motor 12 and a speed reducer 13. The grinding motor 12 is fixedly installed on the support frame 1, and the grinding motor 12 is connected to the grinding disc 7 through the speed reducer 13 and can drive the grinding disc 7 to rotate. In this embodiment, the grinding disc 7 is a resin copper grinding disc.

[0030] Embodiment 4:

[0031] As Figure 2 shown, the present utility model provides another technical solution, a reaction kettle mouth grinding device. Different from Embodiment 1, a baffle 15 is installed on the side wall of the above-mentioned column 2. Rotating the kettle body lifting sliding sleeve 4 clockwise can make the reaction kettle body 5 above the grinding disc 7. And when the kettle body fixing frame 6 contacts the baffle 15, at this time, the reaction kettle mouth 11 and the grinding disc 7 are in the coaxial position. At this time, the fixing between the kettle body lifting sliding sleeve 4 and the column 2 is realized through the locking bolt 16 on the kettle body lifting sliding sleeve 4.

[0032] In this application, the reaction kettle body 5 rotates forward and the grinding disc 7 rotates reversely. The flattening operation of the reaction kettle mouth 11 is realized through the relative movement between the reaction kettle body 5 and the grinding disc 7. From the perspective of the grinding operation, it is not necessary for the reaction kettle mouth 11 and the grinding disc 7 to be strictly coaxially arranged. As long as it is ensured that the grinding disc 7 can contact the reaction kettle mouth 11 and the flattening operation is completed through appropriate pressure and rotation speed; but the coaxial arrangement can greatly improve the processing accuracy, ensure that the reaction kettle mouth has extremely high sealing performance, and the coaxial rotation can also reduce the vibration that may occur during the operation of the equipment, which is of great significance for protecting the accuracy of the equipment and extending its service life.

[0033] Embodiment 5:

Different from Embodiment 1, an electric control box 14 is installed on the support frame 1. In addition, a water tank and a waste water recovery box are also installed. A water pump is installed in the water tank. The water pump is connected to a nozzle through a water pipe, which can realize cooling during the grinding process. The waste water recovery box is used for waste water recovery.

[0035] The above-mentioned electric control box 14 is internally provided with a controller, which can be a PLC controller or an industrial computer. Moreover, the lifting mechanism 3, the kettle body rotation motor 8, the grinding motor 12 and the water pump are all electrically connected to the controller for controlling their operations. Their specific structures and circuits are not within the protection scope of this application, and those skilled in the art can obtain them through common general knowledge, conventional means or simple derivation in this field, so they will not be elaborated here.

[0036] A reaction kettle mouth grinding device provided by the present utility model can drive the reaction kettle body to rotate around the column through the provided kettle body lifting sliding sleeve, kettle body fixing frame and lifting mechanism, and then conveniently move the reaction kettle body above the grinding disc. Moreover, the lifting mechanism can drive the reaction kettle body to move up and down, so that the reaction kettle mouth contacts the grinding disc, facilitating grinding, and the operation is simple; through the provided first driving component and second driving component, the first driving component can drive the reaction kettle body to rotate forward, and the second driving component can drive the grinding disc to rotate reversely. Through the relative rotational movement of the reaction kettle body and the grinding disc, a fast and uniform grinding effect is achieved, improving the grinding efficiency.

[0037] It should be understood that this embodiment is only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the appended claims of this application.
