Automatic shaking-up device for volumetric flask after constant volume treatment

Abstract

The invention discloses an automatic shaking-up device for a volumetric flask after constant volume treatment, belonging to the field of inspection and detection. The automatic shaking-up device disclosed by the invention comprises a pedestal, a machine top cover, a front cover plate, a rear cover plate and a machine shell, wherein the pedestal is arranged at the lower end of the rear cover plate,the machine top cover is arranged at the upper end of the rear cover plate, the rear cover plate, the pedestal and the machine top cover form a cavity, a motor is arranged in the cavity, the motor isfixed on the rear cover plate by virtue of a fixed seat, the motor and the pedestal are connected by virtue of a motor supporting frame, a splint motherboard is arranged on an output shaft of the motor, multiple volumetric flask grooves are formed in the splint motherboard, a splint cover plate matched with the splint motherboard is arranged in front of the splint motherboard, a front cover plateis arranged outside the splint cover plate, and a main control circuit panel is arranged on the front cover plate. The automatic shaking-up device disclosed by the invention effectively solves the problems of an automatic shaking-up action after the constant volume treatment on the volumetric flask, fracture prevention and leakage prevention, is reasonable to design and compact in structure, inspection working efficiency is effectively improved, inspection errors are reduced, and the labor intensity of inspection personnel is reduced.

Description

Technical field [0001] The invention relates to the field of inspection and detection, in particular to a device for automatically shaking a volumetric flask after a constant volume. Background technique [0002] According to the relevant standards of inspection and testing, solvent preparation is a common standard operation in quality inspection work, and this process is mostly carried out in a volumetric flask. Take the preparation of standard solvents as an example, add standard substances in a certain proportion, and then use the prescribed solvent (water, dilute acid, etc.) to make the volume up to the volumetric flask scale, cap and shake for 5-10 minutes to make the standard substances in the volumetric flask well mixed. It can be seen that the shaking operation after constant volume is a repetitive daily work in the field of quality inspection, which not only consumes time and effort, but also directly affects the accuracy of the inspection results. [0003] At present, t...

Problems solved by technology

It can be seen that the shaking operation after constant volume is a repetitive daily work in the field of quality inspection, which is not only time-consuming and labor-intensive, but also directly affects the accuracy of the inspection results

[0003] At present, the shaking devices that have appeared on the market are mostly used for test tubes, Erlenmeyer flasks and other utensils, and only simply snap and fix the test tubes without a protection mechanism. Insufficient shaking may also cause problems such as test tube shock and rupture, solvent spilling, etc.

For the volumetric flask, due to the small upper space, it needs to be shaken according to the standard action. At the same time, the volumetric flask is mostly a thin-walled glass vessel, and it is easy to cause the bottle wall to break when it is violently mechanically shaken without an external protection mechanism. , and the simple oscillating shaking method may lead to insufficient shaking of the solvent, which will affect the follow-up experimental work
