Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a drying device for metering chemical instruments. Background Art

[0002] Chemistry is a basic natural science that studies the composition, structure, properties of substances and the interactions between them. Chemical instruments refer to various equipment and tools used in chemical research, teaching, production and analysis, while metrological chemical instruments usually refer to measuring tools and instruments used in chemical experiments or chemical analysis. They ensure that measurements during the experiment are accurate and reliable. The measuring cylinder is a commonly used instrument in chemical metrology. The measuring cylinder needs to be cleaned after use and then placed in a drying device for drying.

[0003] When the existing drying device is used, the cleaned measuring cylinder is usually directly placed in the drying device. However, water droplets adhere to the inner wall of the measuring cylinder just after cleaning. If the water droplets need to be wiped dry, it will take more time to dry. If there is no extra and dry measuring cylinder in the laboratory, the long wait will delay the chemical experiment. Although the water column in the measuring cylinder can be wiped dry immediately after cleaning, it is usually a manual operation, which is troublesome and slow. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 In the embodiment of the utility model, a drying device for measuring chemical instruments includes a workbench 1, a rectangular groove is opened on the top surface of the workbench 1, a receiving cavity 11 is opened through the bottom end of one side of the workbench 1, a rotating mechanism 2 is arranged inside the receiving cavity 11, a drying mechanism 3 is arranged at the bottom end of the rotating mechanism 2, a wiping mechanism 4 is arranged outside the rotating mechanism 2, the inner bottom surface of the rectangular groove is located in an inclined structure, an inner side surface of the rectangular groove is penetrated and fixed with a water outlet pipe, and the rotating mechanism 2 includes a plurality of evenly distributed and intersecting with the inner bottom surface of the rectangular groove. A cylindrical block 21 is passed through and rotated, a circular tube 22 is fixedly passed through the bottom surface of the cylindrical block 21, a connector 23 is rotatably connected to the inner bottom end of the circular tube 22, the wiping mechanism 4 comprises a bottom plate 41 which moves up and down in the accommodating cavity 11, a rotating ring 42 is passed through and rotated with the circular tube 22 at the corresponding position on the top surface of the bottom plate 41, a plurality of vertical rods 43 passing through the cylindrical block 21 at the corresponding position are fixed at equal angles on the top surface of the rotating ring 42, a sponge cover 44 is detachably connected between the plurality of vertical rods 43 at the same rotating ring 42.

[0023] Specifically, firstly, the diameter of the selected sponge sleeve 44 is slightly larger than the diameter of the measuring cylinder, and then the sponge sleeve 44 is inserted between the plurality of vertical rods 43 at the corresponding positions, and then the cleaned measuring cylinders are respectively inserted outside the sponge sleeve 44 at the corresponding positions. Figure 1 As shown, a cover plate is provided on the top surface of the workbench 1, and the cover plate is a transparent structure. The rotation of the multiple circular tubes 22 can make the cylindrical block 21 drive the multiple vertical rods 43 at the corresponding positions to rotate, thereby driving the sponge sleeve 44 at the corresponding positions to rotate. Since the diameter of the sponge sleeve 44 is larger than the diameter of the measuring cylinder, the sponge sleeve 44 can absorb the water droplets on the inner walls of the two measuring cylinders, and then by moving the bottom plate 41 downward, the moved bottom plate 41 can drive the multiple vertical rods 43 to move downward. Since the bottom end of the sponge sleeve 44 contacts the bottom surface of the rectangular groove, the moved vertical rods 43 can compress the sponge sleeve 44 at the corresponding position. The compressed sponge sleeve 44 can squeeze out the absorbed water and flow out from the water outlet pipe, and then the circular tube 22 is filled with hot air through the drying mechanism 3. When the hot air contacts the inner wall of the measuring cylinder, since the measuring cylinder usually has a pointed mouth, the hot air will flow into the rectangular groove from the pointed mouth along the inner wall of the measuring cylinder, thereby drying the measuring cylinder, thereby reducing the drying time of the measuring cylinder and improving the drying efficiency.

[0026] In this embodiment, when the sponge cover 44 is put on the outer wall of the circular tube 22, the stopper 46 is screwed into the top of the vertical rod 43 at the corresponding position. When the two electric push rods 45 are started, the sponge cover 44 will be compressed under the action of the stopper 46, so that the through hole 24 on the circular tube 22 can leak out, which is convenient for the drying mechanism 3 to dry the measuring cylinder, and the water absorbed by the sponge cover 44 can be squeezed out to prevent the sponge cover 44 from no longer having the water absorption function due to saturation of water absorption.

[0029] In this embodiment, multiple worm gears 26 can be driven by the motor 28 to rotate, and the rotating worm gears 26 can cause multiple worm wheels 25 at corresponding positions to drive the circular tubes 22 at corresponding positions to rotate, so that the sponge cover 44 can be rotated in the measuring cylinder, thereby facilitating the absorption of water droplets on the inner wall of the measuring cylinder, thereby facilitating the drying mechanism 3 to quickly dry the moisture on the inner wall of the measuring cylinder.
