Test tube dryer

Abstract

The invention discloses a test tube dryer. The dryer is of a hollow right quadrangular frustum pyramid structure, each wall board of the dryer is provided with a drainage channel, each drainage channel comprises a vertical drainage groove in the corresponding wall board and a plurality of branch drainage grooves in an upward launching shape towards the two sides of the corresponding wall board, the branched drainage grooves are connected with the corresponding vertical drainage groove, a through hole is formed in each branch drainage groove, a side turning hole plug is embedded on each through hole and is of a middle hollow structure, the diameter of one end of each side turning hole plug is small, the diameter of the other end of each side turning hole plug is large, and the ends, with the small diameter, of the side turning hole plugs are connected with a drying tube through threads; a heating air blowing mechanism is arranged at the top end of the dryer and comprises a shell, a motor arranged on the shell and a fan connected with the motor through a rotating shaft; a heating wire connected to the inner wall of the shell is arranged below the fan, an air outlet communicated with the interior of a dryer cavity is formed below the shell, and is connected with an air supply channel through a divided manifold, the air supply channel corresponds to the inner board face of each wall board through the corresponding branch pipe, the dryer can rapidly evaporate water remaining in the test tube to dryness, and water in the test tube can flow down through the drainage channels and is recycled.

Description

technical field

[0001] The invention belongs to the field of chemical utensils and equipment, in particular to a test tube dryer. Background technique

[0002] In various experiments, the test tube is a basic experimental equipment commonly used to assemble various solutions. It is generally reused many times after cleaning, and the presence of water in the cleaned test tube affects the accuracy of the experimental data. In order to avoid the influence of water on the experimental data, the water in the test tube must be removed before use, and the speed of natural evaporation is relatively slow, and water stains will be left. For some experiments that require high precision, the remaining water on the test tube Water stains will affect the results of the analysis, and in the process of natural air drying, the dust in the air will adhere to the test tube due to the long-term wetting of the inner wall of the test tube, causing re-contamination of the test tube. In order to en...
