The spraying material ring 2 is connected to the lifting member on the lifting and adjusting frame 1. The spraying material ring 2 is used to connect a plurality of spraying components 3. The spraying material ring 2 and the spraying components 3 are positioned inside the reaction kettle through the lifting and adjusting frame 1. The lifting and adjusting frame 1 can control the spraying material ring 2 to drive the spraying components 3 to perform lifting operations inside the reaction kettle, facilitating the adjustment of the positions of the spraying material ring 2 and the spraying components 3 inside the reaction kettle. A material pipe 21 is fixedly connected to the top of the spraying material ring 2, and the material pipe 21 is used to introduce the material liquid into the spraying material ring 2.

[0020] A plurality of spraying components 3 are respectively arranged in a ring below the spraying material ring 2. The spraying component 3 is composed of a fixing frame 31, a steering driving member 32, and a spraying head 33. A fixing rod 311 is fixedly connected to the top of the fixing frame 31, and the top end of the fixing rod 311 is fixedly connected to the bottom of the spraying material ring 2, stably connecting the fixing frame 31 below the spraying material ring 2. A rotating rod 331 is fixedly connected to the tail end of the spraying head 33, and the rotating rod 331 is rotatably connected to the inside of the fixing frame 31, enabling the spraying head 33 to be rotatably connected to the inside of the fixing frame 31. A communicating pipe 332 is fixedly connected to the tail end of the spraying head 33, and the top end of the communicating pipe 332 is fixedly connected to the spraying material ring 2. The communicating pipe 332 communicates with the spraying material ring 2.
