Furthermore, "multiple" means two or more.

[0031] like Figure 1 As shown, the waste liquid collection device 100 provided in this embodiment of the present invention includes multiple collection tanks 11 and multiple collection buckets 12. The multiple collection tanks 11 are arranged above the experimental platform 200 and correspond one-to-one with multiple liquid outlets 331 of the reagent adding component 300. The collection tanks 11 are located below the liquid outlets 331, and the vertical distance between the collection tanks 11 and the liquid outlets 331 is adjustable. A drain pipe 13 is connected to each collection tank 11. A locking block 111 is provided on one side of each collection tank 11, and a locking slot 112 is provided on the other side. The multiple collection tanks 11 are sequentially connected by locking blocks 111 and locking slots 112, with the upper limit of the locking block 111 in the horizontal direction located at the upper limit of the locking slot 112, and the locking block 111 movably inserted into the locking slot 112 in the vertical direction. The multiple collection buckets 12 are arranged inside the experimental platform 200, and the multiple collection tanks 11 and multiple collection buckets 12 are connected one-to-one via the drain pipe 13.

[0032] The reagent addition assembly 300 includes a delivery pump 31, an inlet pipe 32, and an outlet pipe 33. Multiple inlet pipes 32, multiple delivery pumps 31, and multiple outlet pipes 33 are connected in a one-to-one correspondence. One end of the inlet pipe 32 is connected to the inlet of the delivery pump 31, and the other end is connected to the reagent bottle 400. One end of the outlet pipe 33 is connected to the outlet of the delivery pump 31 and extends to the collection tank 11; the other end of the outlet pipe 33 serves as the outlet 331 located above the collection tank 11. The inlet pipe 32, outlet pipe 33, and drain pipe 13 are all acid and alkali resistant.

[0033] The delivery pump 31 can deliver the bubbles and residual reagents in the liquid inlet pipe 32 and the liquid outlet pipe 33 to the liquid outlet 331 for discharge, which is received and collected by the collection tank 11 below. At the same time, the reagent in the reagent bottle 400 is also delivered to the liquid outlet 331, and the delivery pump 31 continues to operate, so that the liquid outlet 331 discharges the reagent to be added.

[0034] Among them, a plurality of collection tanks 11 are connected in sequence along the straight line direction, and the clamping block 111 and the clamping groove 112 of the adjacent two collection tanks 11 are clamped and matched, so that the plurality of collection tanks 11 form a modularized collection tank assembly. In practical application, a corresponding number of collection tanks 11 and collection barrels 12 can be configured according to the number of reagent bottles 400 to realize separate collection of multiple reagents. The positions of the plurality of liquid outlets 331 of the reagent adding assembly 300 are usually uniformly spaced in sequence along the straight line direction. Connecting a plurality of collection tanks 11 to form a modularized collection tank assembly can facilitate the quick correspondence of the positions of the plurality of collection tanks 11 and the plurality of liquid outlets 331, modularize and standardize the waste liquid collection, and be beneficial to improve the waste liquid treatment efficiency.

In this way, a plurality of collection tanks 11 can be separated from each other in the vertical direction and can be limited by each other in the horizontal direction.

[0036] Since the distance between the collection tank 11 and the liquid outlet 331 is adjustable, when it is necessary to discharge waste liquid, the distance between the collection tank 11 and the liquid outlet 331 can be adjusted to be small, so as to avoid the waste liquid from splashing onto the experiment table 200 when falling into the collection tank 11. When it is necessary to move a vessel with a large height size to below the liquid outlet 331 for reagent addition, the distance between the collection tank 11 and the liquid outlet 331 can be adjusted to be large, so as to avoid the collection tank 11 from interfering with the reagent addition.

[0037] In the process of discharging waste liquid, the waste liquid flows through the collection tank 11 and the liquid discharge pipe 13 in sequence and is discharged into the collection barrel 12, and the waste liquid collected by the collection barrel 12 is manually taken away for treatment. It can be understood that the volume of the collection barrel 12 is greater than that of the collection tank 11, so as to reduce the number of personnel treatment. Optionally, the volume of the collection barrel 12 is greater than or equal to that of the corresponding reagent bottle 400.
