Circulating pump, spray-wash system, washing machine and washing method

Abstract

The invention provides a circulating pump, a spray-wash system, a washing machine and a washing method. The circulating pump comprises a motor, an impeller and a volute. The motor comprises a motor casing and an output shaft. The impeller is mounted on the output shaft of the motor. The volute is mounted on the motor casing and arranged outside the impeller in a covering manner. The volute is provided with a water inlet located in the center position of the volute, a first water outlet and a second water outlet, wherein the first water outlet and the second water outlet deviate from the center position of the volute. The washing machine is full-automatic washing equipment special for a laboratory; manual washing can be completely replaced, and quite high washing cleanliness and a stable washing effect can be obtained through the washing machine; and the requirement for traceability can be met.

Description

technical field [0001] The present invention generally relates to the field of washing machines, in particular to a circulation pump, a spray washing system, a washing machine and a cleaning method for utensils. Background technique [0002] At present, glassware commonly used in various laboratories, such as beakers, test tubes, pipettes, volumetric flasks, etc., are cleaned manually, which not only takes up a lot of manpower, but also has low cleaning efficiency, and the uniformity of cleanliness of the containers is poor, and the cleaning effect is also poor. Difficult to guarantee. [0003] In response to the above problems, some laboratories try to use dishwashers instead of manual cleaning of various utensils. However, since the dishwasher is suitable for containers with particulate matter such as grease or food residues, the main design of the dishwasher is to remove grease and filter out food residues. High-precision experiments require high-clean vessels, especial...

AI Technical Summary

Problems solved by technology

High-precision experiments require high-clean vessels, especially in precise quantitative analysis and biological experiments, residual metal ions and biological contamination will have a huge impact on experimental results

Therefore, laboratory utensils have higher requirements for cleanliness, and the cleanliness of final cleaning is required to reach PPM level or even PPB level, but the design of dishwashers cannot meet this cleanliness requirement
