Description

Buret belt cleaning device for food detection Technical Field The utility model relates to the technical field of glass instrument cleaning equipment for food detection, in particular to a burette cleaning device for food detection. Background In the food detection experiment, a burette is a common glass instrument for the projects of acid-base titration, salt content measurement and the like. The traditional burette cleaning mode mainly relies on manual brushing or soaking cleaning. When in manual brushing, an operator needs to hold the hairbrush to repeatedly extend into the slender pipe wall to brush and rub the hairbrush back and forth, but the hairbrush is difficult to enter a narrow gap at the piston part, long-term residual solution is easy to crystallize around the piston to cause clamping, the burette needs to be soaked in the cleaning liquid for a long time during soaking and cleaning, the time is long, a large amount of clean water is still needed to be used for flushing after soaking, and the requirements of emergency detection tasks are difficult to meet. In addition, residual strong acid, strong alkali or organic solvent on the inner wall of the burette after use volatilizes choking smell in the dumping process, and the pipeline can be corroded by directly pouring the strong acid, the strong alkali or the organic solvent into a water tank, and the steps of transferring and neutralizing treatment after collecting by adopting a waste liquid barrel are complex, and the risk of spilling and leaking is also existed in the operation process, so that potential safety hazards and inconvenient operation are brought to experimental staff. In order to solve the problems, the application provides a burette cleaning device for food detection.
