Cleaning and drying instrument for laboratory test tubes

Abstract

The invention provides a cleaning and drying instrument for laboratory test tubes. The cleaning and drying instrument comprises test tube ports, an air storage pipeline, a conical air outflow end, an electric stove wire and a thermal insulation plate; the electric stove wire is fixedly installed on the inner side of the thermal insulation plate, and the thermal insulation plate is fixed to the inner wall of a working bin; the left side of the working bin is fixedly connected to the conical air outflow end, the air storage pipeline is fixed to the conical air outflow end, and generated air flows through the conical air outflow end to arrive at the air storage pipeline through the working bin; the outside of the air storage pipeline is fixedly connected with the multiple rows of test tubes, an air inflow valve is installed on each test tube port, the air inflow valves can control air inflowing, and the corresponding air inflow valves on the test tube ports in which no test tubes are inserted can be selectively closed; and a rotating fan is connected with a double-output-shaft motor, cleaning of the test tubes is not influenced while the test tubes are dried, meanwhile, cold and hot wind can be selected for drying, the mode that the thermal insulation plate makes contact with the inner wall of the working bin is adopted for heating the electric stove wire in the working bin, and damage of a device is effectively prevented.

Description

technical field [0001] The invention relates to a test tube cleaning and drying instrument, in particular to a laboratory test tube cleaning and drying instrument. Background technique [0002] The test tube is one of the most important experimental utensils in the experimental process. Most of the experiments in the laboratory use the test tube. The test tube can not only be used as a reaction vessel, but also as a holding device for configuring solvents; The unique structure makes it difficult to clean. At the same time, the inner wall of the cleaned test tube is often dipped in water droplets and cannot be used immediately. The traditional test tube drying method is natural drying. The dry quality is not guaranteed, and the drying time is prolonged, and the drying method of flowing wind can shorten the time and ensure the quality. Contents of the invention [0003] The object of the present invention is to provide a laboratory test tube washing and drying instrument to...
