Description

Technical Field

[0001] The utility model belongs to the technical field of airflow dryers, and in particular relates to an airflow dryer for glass instruments used in laboratories. Background Art

[0002] In biological and chemical laboratories, glassware is an indispensable experimental equipment in the process of basic experimental research. The cleanliness of glassware has a great influence on the results and accuracy of the experiment. After the glassware is cleaned, the ash is dried through an air flow dryer. The glassware is placed upside down on the drying tube, and then the equipment is started. At this time, the heater in the box will heat the hot air through the fan to form an airflow and discharge it from the heat outlet to dry the glassware.

[0003] A novel airflow dryer for glassware is disclosed in Chinese patent application No. 201721564515.X. The patent comprises two semi-circular metal sheets and screws on the upper part of the drying tube, wherein the two semi-circular metal sheets are connected to the lower hollow cylindrical metal tube and opened at a certain angle. The opening angle of the semi-circular metal sheets can be controlled by controlling the position of the nut to adapt to glassware of different diameters. However, there are multiple drying tubes on the box during use, and glassware will be placed on each drying tube during the drying process. If there are fewer glassware to be dried during use, only fewer glassware can be placed on a part of the drying tubes for drying, and the remaining drying tubes are not equipped with glassware. When the drying process does not involve glassware, the heat outlet holes in the drying tubes where no glassware is placed will also discharge hot air to the outside. This will not only cause waste, but also reduce the amount of hot air in the box, affecting the drying effect of the glassware. For this reason, we propose an airflow dryer for laboratory glassware. Utility Model Content

[0032] The working principle and use process of this utility model:

[0033] When the utility model is in use, the valve 206 on the connecting pipe 207 is opened, and then the glassware to be dried is placed upside down on the top of the drying tube 102. At this time, the drying tube 102 begins to fall due to the weight of the glassware, driving the limit ring 210 and the sealing ring 205 to move. At this time, the spring 202 begins to stretch due to the fall of the limit ring 210, and the bottom of the sealing ring 205 penetrates into the interior of the installation tube 200. Finally, the lower surface of the sealing ring 204 at the bottom of the drying tube 102 contacts the top of the installation tube 200. At this time, the sealing ring 204 at the bottom of the drying tube 102 is in contact with the top of the installation tube 200. The connecting hole 208 on the ring 205 is connected to the top of the connecting pipe 207. At this time, the equipment is started, and then the hot air passes through the connecting pipe 207, the sealing ring 205 and the drying pipe 102, and finally comes out from the heat outlet 103 to dry the glassware. The drying pipe 102 without glassware will not drop. At this time, it is a closed circuit state, and hot air will not be discharged from the drying pipe 102 without glassware. When the glassware is dried, the glassware is taken out, and the drying pipe 102 moves upward and returns to its original position according to the above reverse principle.

[0034] When the device is not in use, the rubber blocking column 300 is used to block the connecting hole 208 exposed to the outside, and then the handle 302 is held to make the rubber blocking rod 301 block the heat outlet hole 103 exposed to the outside, so as to prevent external foreign matter from entering the connecting hole 208 and the heat outlet hole 103. When the device is used, the rubber blocking column 300 and the rubber blocking rod 301 can be pulled out according to the reverse principle mentioned above.
