A delivery pipe 305 is connected to the middle of the bottom of the storage tank 301, and a diverter seat 314 is arranged below the delivery pipe 305. A servo motor 306 is installed on one side of the top of the drip tank body 1, and a liquid inlet pipe 4 is connected to the middle of the top of the storage tank 301; a transmission column 309 is connected to the output end of the servo motor 306, and the drip tank body 1 A fixed plate 307 is welded to the middle of the inner wall, and liquid inlets 308 are opened on both sides of the fixed plate 307; a first synchronous wheel 310 is connected to the side of the transmission column 309 away from the servo motor 306, and the first synchronous wheel 310 is connected to the second synchronous wheel 312 through a synchronous belt 311, and a rotating column 313 is welded inside the second synchronous wheel 312, and the top of the outer wall of the rotating column 313 is welded to the diverter seat 314; the floating plate 303 is an "O"-shaped structure, and the cross-section of the floating plate 303 and the scale rod 304 is a "U"-shaped structure, and the top of the storage tank 301 is opened on both sides.

[0022] In specific implementation, in the chemical production process, in order to transport and store liquid through the drip tank, after the liquid reagent is introduced into the storage tank 301 through the liquid inlet pipe 4, since the middle of the outer wall of the storage tank 301 is connected with a transparent observation window 302, and the outer wall of the transparent observation window 302 is provided with scale lines, the amount of liquid in the storage tank 301 is first checked through the transparent observation window 302, and since the storage tank 301 is connected with a floating plate 303, the liquid sample will generate a thrust on the floating plate 303 during this process, so that the floating plate 303 rises with the increase of the liquid sample, and since the floating plate 303 is connected to the scale rod 304, the upward movement of the floating plate 303 will drive the scale rod 304 moves upward together, thereby increasing the portion of the scale rod 304 moving out of the storage tank 301. At this time, the scale rod 304 moves upward to assist the staff to check the amount of liquid in the storage tank 301, and then accurately control the total amount of the liquid sample to be transported to correspond to the actual demand.

[0023] When the liquid sample enters the inside of the dropping tank body 1 through the delivery pipe 305, the servo motor 306 is started in advance. Since the output end of the servo motor 306 is connected to the transmission column 309, the start of the servo motor 306 will drive the transmission column 309 to rotate, and then the transmission column 309 rotates to drive the first synchronous wheel 310 to rotate, and since the first synchronous wheel 310 is connected to the second synchronous wheel 312 through the synchronous belt 311, the rotation of the first synchronous wheel 310 will drive the second synchronous wheel 312 to rotate together, and then the rotation of the second synchronous wheel 312 will drive the rotating column 313 to rotate, and since the rotating column 313 is connected to the diverter seat 314, the rotation of the rotating column 313 will drive the diverter seat 314 to rotate together, and at this time, the high-speed rotating diverter seat 314 is rotated. 14 will generate centrifugal force, and then when the liquid sample enters the inside of the dropping tank body 1 through the conveying pipe 305, it will contact the high-speed rotating diverter seat 314, and then the liquid sample will be dispersed to all directions through the centrifugal force, and then the dispersed liquid sample will be introduced into the bottom of the inner wall of the dropping tank body 1 through the liquid inlet 308 inside the fixed plate 307, so that the liquid sample is evenly dispersed and enters the bottom of the dropping tank body 1, preventing the liquid sample from entering the bottom of the dropping tank body 1 from a certain place, and then the liquid sample is more effectively mixed with the existing liquid in the tank, avoiding the situation of excessively high or low local concentration, and reducing the dependence on stirring, so that when the dropping tank is used for chemical production, it plays a role in facilitating the quantitative addition of liquid and uniform liquid inflow.

This is the prior art and will not be elaborated on here. The total amount of the liquid sample to be transported is accurately controlled by the auxiliary mechanism 3 to make it correspond to the actual demand, thereby preventing excessive addition of liquid reagent, ensuring that the liquid reagent is added according to a predetermined proportion and amount, and reducing unnecessary waste; and making the liquid sample evenly distributed into the bottom of the dropping tank body 1, preventing the liquid sample from entering the bottom of the dropping tank body 1 from a certain place, thereby avoiding the situation where the local concentration is too high or too low.
