Description

Technical Field

[0001] The utility model relates to the technical field of laboratory instruments, in particular to an instrument bottle shaking device. Background Art

[0002] The power plant's chemical oil quality technical supervision and analysis project requires acid value determination of oil samples. This determination consists of two steps: 5-minute reflux in a constant-temperature water bath and titration. The acid value determination process requires constant shaking of the conical flask during reflux. However, this process is performed in a 90°C constant-temperature water bath, requiring manual shaking with gloves and a separate 5-minute timer for each shake, which is inefficient. Furthermore, the uneven manual shaking force impedes oil-liquid separation, leading to errors in the oil sample analysis results. Furthermore, the titration process must be completed within 3 minutes, but the temperature of the newly removed conical flask is high, requiring gloves to be worn, which also reduces titration efficiency.

[0019] Specifically, a motor 10 is provided inside the base 1, and the motor 10 is transmission-connected to the bottom of the column 2;

[0020] The motor 10 is used to drive the column 2 to rotate back and forth, so as to drive the bracket 3 and the instrument clamp 4 to shake the instrument bottle 6.

[0021] Preferably, the rear end of the bracket 3 can be slidably sleeved on the column 2 and fixed by tightening screws 5.

[0022] Optionally, the support 3 comprises a foldable support.

[0023] Optionally, an adjustable valve 7 is provided at the connection between the instrument clamp 4 and the bracket 3 for adjusting the tightness of the instrument clamp 4 holding the instrument bottle 6 .
