[0019] The buffer mechanism includes a fixed seat 7, a connecting rod 8, a motor 9, and a buffer seat 10; the connecting rod 8 is arranged on the fixed seat 7, and the other end of the connecting rod 8 is arranged on the inner wall of the cover body 3, the buffer seat 10 is located above the fixed seat 7, the motor 9 is arranged in the fixed seat 7, and the output end of the motor 9 is fixedly connected to the bottom of the buffer seat 10 through a rotating shaft; the buffer seat 10 is a pagoda-shaped structure, and the outer wall of the buffer seat 10 is curved, and the spiral buffer groove 6 is located at the top of the pagoda-shaped buffer seat 10.

[0020] In this embodiment: the raw liquid enters the feed hopper 4 and falls into the spiral buffer groove 6. The spiral buffer groove 6 prevents the raw liquid from directly entering the tank body 2 through the connecting pipe 5 vertically downward. Instead, the raw liquid slowly spirals downward through the spiral structure of the spiral buffer groove 6. The spiral buffer groove 6 has a buffering effect on the raw liquid, reducing the impact force of the raw liquid falling, and the bottom of the spiral buffer groove 6 is located above the buffer mechanism. The motor 9 is started, and the buffer seat 10 rotates slowly. The buffer seat 10 has a pagoda-shaped structure, and the outer wall of the buffer seat 10 is curved. The raw liquid in the spiral buffer groove 6 falls onto the buffer seat 10, and the buffer seat 10 again has a buffering effect on the raw liquid, so that the raw liquid will be directly sprayed on the tank wall of the tank body 2. When the subsequent mixing and distillation is carried out, it will not cause impact on the equipment, and the pressure wave inside the equipment can be minimized, so as not to cause impact on the subsequent mixing and distillation equipment. During long-term processing, the device is not easily damaged, thereby improving the service life of the device.

[0025] As a technical optimization solution of the utility model, a spiral blade 15 is arranged in the feeding pipe 13 .

[0026] In this embodiment, the spiral blades 15 play a blocking role, further reducing the flow rate of the stock solution.

[0029] Working principle: First, the raw liquid enters the feeding pipe 13 through the feeding hopper 14. The feeding pipe 13 is arranged horizontally to reduce the flow rate of the raw liquid, making it easy for the raw liquid to slowly flow into the feeding hopper 14. The guide hopper 11 plays a diversion role, making it easy for the raw liquid in the feed hopper 4 to fall into the spiral buffer groove 6. The spiral structure of the spiral buffer groove 6 makes the raw liquid slowly spiral downward. The spiral buffer groove 6 plays a buffering role on the raw liquid, reducing the impact force of the raw liquid falling, and the bottom of the spiral buffer groove 6 is located above the buffer mechanism. Start the motor 9, and the buffer seat 10 rotates slowly. The buffer seat 10 has a pagoda-shaped structure, and the outer wall of the buffer seat 10 is curved. The raw liquid in the spiral buffer groove 6 falls on the buffer seat 10, and the buffer seat 10 plays a buffering role on the raw liquid again, so that the raw liquid will be directly sprayed on the tank wall of the tank body 2. When the subsequent mixed distillation is carried out, it will not cause impact on the equipment, and it can also minimize the pressure wave inside the equipment, and thus will not cause impact on the subsequent mixed distillation equipment.
