Description

Technical Field

[0001] The utility model relates to the technical field of test tube drying, in particular to a hot air drying rack for test tubes. Background Art

[0002] A glass test tube is a container for a small amount of reagent reaction and can also be used to collect a small amount of gas. According to its use, it is often divided into a bottle-mouth test tube, a turned-mouth test tube, etc. After the glass test tube is used, residues will remain inside the glass test tube. To ensure that the internal reagent reaction will not be affected when the glass test tube is used next time, it is necessary to ensure the cleanliness of the glass test tube and perform a cleaning treatment on the glass test tube. After the glass test tube is cleaned, water stains will inevitably remain inside the glass test tube. These water stains usually need to be drained and then dried.

[0003] Since the glass test tube needs to be drained first and then dried, when the existing glass test tube is placed on the drying rack for drying, due to the need to wait for draining, the drying efficiency is low.

[0004] In summary, there is a need for a hot air drying rack for test tubes at present. Content of the Utility Model

[0032] The protective pad 110 can protect the clamping surface of the glass test tube to avoid clamping damage.

[0033] Embodiment Three

[0034] As Figures 1 - 5 shown, on the basis of the above embodiment, this embodiment further gives the following content:

[0035] In this embodiment, the drying box 9 includes a blower 901. The blower 901 is provided on one side of the drying box 9. A filter screen is provided at the air inlet of the blower 901. The blower 901 is connected to an air delivery pipe 903. The air delivery pipe 903 is disposed through the inside of the drying box 9. One end of the air delivery pipe 903 away from the blower 901 is connected to an external hose 8. The drying box 9 further includes an electric heating plate 902. An electric heating plate 902 and an ultraviolet germicidal lamp 904 are provided inside the drying box 9. The ultraviolet germicidal lamp 904 is provided inside the electric heating plate 902.

[0036] The gas flowing in the air delivery pipe 903 is further sterilized by the ultraviolet germicidal lamp 904, improving the cleanliness and hygiene of the hot air for drying.

[0037] The working principle and usage process of the present utility model are as follows:

[0038] In the usage state:

[0039] First step: Pull the front pull frame 112. The pull frame 112 acts on the first clamping frame 108 through the connecting plate frame 111. The first clamping frame 108 compresses the spring 107, inserts the glass test tube through the corresponding opening groove 106, releases the pull frame 112, and under the action of the corresponding spring 107, the first clamping frame 108 is pushed to cooperate with the second clamping frame 109 to clamp and fix the glass test tube. The protective pad 110 can protect the clamping surface of the glass test tube to avoid clamping damage.

[0040] Second step: First, clamp a batch of glass test tubes on the front side of the limit frame 105 for water drainage. The water droplets are collected by the front collection box 113. After the water drainage is completed, under the action of the electric telescopic rod 104, the sliding frame 102 is pulled to move and adjust on the slide rail 101, so that the glass test tube is positioned above the through-opening groove 10. At the same time, the glass test tube clamped and fixed at the rear opening groove 106 of the limit frame 105 is drained of water, and the water stains are collected by the rear collection box 113 for subsequent drying treatment, which helps to improve the drying efficiency.

[0041] Third step: Drive the lead screw 3 to rotate through the motor 4, so that the moving frame 5 moves and adjusts on the lead screw 3, so that the air blowing pipe 6 rises to an appropriate position inside the glass test tube. Gas is drawn in through the blower 901 and conveyed through the air delivery pipe 903. The filter screen provided at the air inlet of the blower 901 reduces the entry of dust and impurities. The gas conveyed in the air delivery pipe 903 is heated by the electric heating plate 902. The gas flowing in the air delivery pipe 903 is further sterilized by the ultraviolet germicidal lamp 904. The heated gas is conveyed to each air blowing pipe 6 through the external hose 8 and the horizontal pipe 7 to blow hot air inside the glass test tube for drying.
