[0046] One side of the base (1) is provided with a control device (31), and the control device (31) is in electrical connection with the first motor (5), the electric telescopic rod (20) and the second motor (26).

[0047] The control device (31) is provided with control buttons and a display screen, which are used for the operation control of the first motor (5), the electric telescopic rod (20) and the second motor (26) during the operation of the device.

[0048] The residual liquid automatic collection device comprises an electric telescopic rod (20) installed at the bottom of the lifting support (11), a first connecting rod (21) connected to the bottom of the electric telescopic rod (20), a disc (22) connected to the bottom of the first connecting rod (21), a second connecting rod (23) connected to the bottom of the disc (22), a collection tank (24) connected to the bottom of the second connecting rod (23), a third connecting rod (25) connected to the side of the disc (22), a second motor (26) installed at the bottom of the third connecting rod (25), a conveying pipe (27) connected to the top of the collection tank (24), and a receiving pipe (29) connected to one side of a rotary joint (28) connected to one end of the conveying pipe (27).

[0049] When the reaction is completed, the operator timely closes the burette valve (19), controls the second motor (26) to drive the upper joint part of the rotary joint (28) to rotate together with the receiving pipe (29) through the control device (31), aligns the receiving pipe (29) with the bottom of the burette (18), controls the electric telescopic rod (20) to drive the first connecting rod (21) to rise, and makes the bottom of the receiving pipe (29) contact with the bottom of the burette (18), so that the residual liquid remaining in the burette (18) below the burette valve (19) is received, the residual titration liquid in the receiving pipe (29) is recovered into the collection tank (24) through the passage formed by the receiving pipe (29), the rotary joint (28) and the conveying pipe (27), and the titration agent collected in the collection tank (24) is discharged for recycling by opening a liquid discharge valve (32).

[0050] A screw hole is formed through the side surface of one side of the titration mechanism mounting frame (14) and the inner side thereof and is threadedly connected with the second locking screw (15).

[0051] When the fixing seat (16) is placed in the titration mechanism mounting frame (14), the second locking screw (15) is tightened to fix the titration mechanism mounting frame (14).

[0052] The working principle and usage process of this utility model: When using this device, after loosening the first locking screw (12), the height of the lifting bracket (11) can be adjusted so that the bottom height of the burette (18) can adapt to the height of the conical flask to be used. After the adjustment is completed, the first locking screw (12) is tightened again, and the conical flask to be used to hold the solution to be tested is placed inside the conical flask placement seat (7). The position of the clamp (9) is adjusted by rotating the adjusting screw (8). The conical flask is fixed by the clamp (9) cooperating with the inner wall of the conical flask placement seat (7). Before installing the titrant bottle (17), the titrant is injected into the titrant bottle (17), and the titration mechanism mounting bracket (14) is rotated so that the fixed seat is adjusted. (16) The first threaded connector on the fixed seat (16) is turned downwards. After the titrant bottle (17) is threadedly connected to the first threaded connector on the fixed seat (16), the titration mechanism mounting bracket (14) can be rotated to flip it over and open the liquid inlet control valve (30). The titrant in the titrant bottle (17) can then enter the burette (18). When the titrant inside the burette (18) is filled to a certain amount, the liquid inlet control valve (30) can be closed to stop adding titrant to the burette (18). Then the titration work can begin. The first motor (5) drives the gear (6) to rotate, which drives the annular turntable (3) to rotate synchronously, so that the mouth of the conical bottle inside the conical bottle holder (7) moves to the bottom of the burette (18). Then, the burette valve (19) can be opened, allowing the titrant inside the burette (18) to flow downwards and drip into the conical flask inside the conical flask holder (7) through the dripping port at the bottom of the burette (18). The titrant reacts with the solution to be tested in the conical flask. When the reaction is complete, the operator promptly closes the burette valve (19) and controls the second motor (26) via the control device (31) to rotate the upper connector part of the rotary joint (28) along with the receiving tube (29), aligning the receiving tube (29) with the bottom of the burette (18). The operator also controls the electric telescopic rod (20) to raise the first connecting rod (21), bringing the bottom of the receiving tube (29) into contact with the bottom of the burette (18), thus cleaning the solution remaining in the burette (18). 8) The residual liquid located below the burette valve (19) is collected and flows into the receiving pipe (29). The residual titrant is then collected in the collection tank (24) through the passage formed by the receiving pipe (29), rotary joint (28), and delivery pipe (27). At the same time, the first motor (5) drives the gear (6) to rotate along with the annular turntable (3), causing the conical flask holder (7) to move with the rotation of the annular turntable (3), so that the next set of conical flask holders (7) moves to the bottom of the burette (18). At this time, the amount of titrant used in this titration can be observed through the scale on the side of the burette (18), and the concentration and content of the substance to be measured in the conical flask can be calculated. After the residual liquid at the bottom of the burette (18) is drained,The second motor (26) and electric telescopic rod (20) can be controlled to operate, driving the receiving pipe (29) to reset and move away from below the burette (18). At this time, the next set of titration tests can be carried out. After the titration is completed, the residual liquid in the burette (18) located inside the burette valve (19) is collected by the residual liquid collection device. This can prevent this part of the residual liquid from continuing to drip into the conical flask and causing waste. Opening the drain valve (32) can discharge the titrant collected in the collection tank (24) for recycling. At the same time, by setting the automatically rotating annular turntable (3) that can carry multiple conical flasks at the same time, multiple sets of samples can be continuously tested automatically. Compared with the existing technology, when multiple sets of samples are continuously tested, the process of changing conical flasks between two testing processes is eliminated. The disassembly and replacement of conical flasks after the test is completed can be carried out at the same time as another set of conical flasks is tested, which can effectively improve the testing efficiency.
