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...

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 ensure the accuracy of the experimental data, no Do not clean again, time-consuming and labor-intensive

[0003] The commonly used method of drying the water on the inner wall of the test tube is to dry the test tube at a high temperature in a constant temperature drying box, but it takes a long time, and there is no special test tube rack in the drying box, and there will still be water stains in the flat test tube, while The temperature of the test tube after drying is high, it is difficult to handle, and it is easy to break the test tube. In order to quickly dry the test tube, a hair dryer is often used to blow hot air directly at the test tube mouth, but the test tube mouth is small, and the hot air blown by the hair dryer is not easy to blow in. In the test tube, sometimes it may even cause burns to the hands. During the drying process of the tubular dryer, the water droplets on the glass instrument cannot be discharged in time, which will cause energy waste for the dryer, and some of them are drying There is a water receiving plate under the water receiving plate, and a water diversion pipe is set at the bottom of the water receiving plate, and the water diversion pipe flows to the drain outlet, but it is provided with a drain outlet, which must be close to the water tank, and the position of the dryer is limited
