Description

Technical Field

[0001] This utility model relates to the field of drying device technology, specifically to a novel rotatable airflow drying device for glass instruments. Background Technology

[0002] Instruments made of glass are called glass instruments. Glass instruments are widely used in laboratories because glass has high chemical stability, thermal stability, good transparency, certain mechanical strength, and good insulation properties. Glass instruments made using the excellent properties of glass are widely used in various laboratories, such as chemical laboratories, medical testing laboratories, biological laboratories, scientific research laboratories, and teaching laboratories.

[0003] For example, Chinese Patent (CN220892762U) discloses an airflow drying device for laboratory glassware, relating to the field of glassware drying technology. It includes a dryer body and a drying tube. A temperature controller is fixedly connected to the surface of the dryer body, and a control panel is also fixedly connected to the surface of the dryer body. A fixing device is provided on the surface of the dryer body, comprising two connecting frames, both of which are fixedly connected to the arc surface of the dryer body. A rotating plate is rotatably connected to the surface of each of the two connecting frames, and a sliding rod is slidably connected to the surface of the rotating plate. A disc is fixedly connected to the end of the sliding rod away from the rotating plate. This airflow drying device for laboratory glassware, by setting the fixing device, can be attached to the tabletop of the laboratory by suction cups, limiting the position of the dryer body and preventing it from moving during placement, thus facilitating the placement and use of the dryer body.

[0004] The aforementioned device involves placing the glass instrument on a drying tube and then using airflow to dry the interior of the instrument. However, the relative position of the drying tube and the glass instrument remains unchanged, which may result in poor drying in some areas and require a longer time to achieve the desired drying effect. This fixed position may prevent the airflow from effectively removing all moisture, increasing the drying time and affecting the drying efficiency. To address these issues, a novel rotatable airflow drying device for glass instruments is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a novel rotatable airflow drying device for glass instruments. It solves the problem of the current method of placing the glass instrument on a drying tube and then using airflow to dry the inside of the instrument. However, the relative position of the drying tube and the glass instrument remains unchanged, which may result in poor drying effect in some areas and may require a longer time to achieve the desired drying effect. This fixed position may also cause the airflow to be unable to effectively remove all moisture, increasing the drying time and affecting the drying efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel rotatable airflow drying device for glass instruments, comprising a drying chamber, a door rotatably connected to the front of the drying chamber via a hinge, a water collection tank fixedly connected to the bottom surface inside the drying chamber, an inclined guide plate fixedly connected to the upper part of the water collection tank, a heating chamber fixedly connected to the rear of the drying chamber above the water collection tank, an axial flow fan fixedly connected to the rear of the heating chamber, a plurality of heating wires fixedly connected inside the heating chamber, and a rotating assembly arranged at the upper part of the interior of the drying chamber.

[0007] Preferably, an observation window is provided on the front side of the door for observation, and a drain pipe is fixedly connected to the lower right side of the drying box, with the end of the drain pipe passing through the right side wall of the drying box and connected to the water collection tank.

[0008] Preferably, the rotating assembly includes a fixed disk, which is fixedly connected to the top wall inside the drying oven. A connecting disk is fixedly connected to the center of the bottom surface of the fixed disk, and a connecting ring is fixedly connected to the outer side of the bottom of the fixed disk. An arc-shaped T-shaped limiting groove is formed between the connecting disk and the connecting ring.

[0009] Preferably, a plurality of first connecting rods are fixedly connected to the bottom of the connecting ring, and a toothed ring is fixedly connected to the bottom of the connecting ring through the first connecting rods.

[0010] Preferably, the rotating assembly further includes a servo motor, which is fixedly installed on the top of the drying chamber. The output end of the servo motor passes through the top wall of the drying chamber and the middle of the connecting plate and is fixedly connected to a drive shaft. A first gear is fixedly connected to the bottom of the drive shaft.

[0011] Preferably, at least three second gears are provided between the first gear and the gear ring, with the two sides of the second gear meshing with the first gear and the gear ring respectively, and the bottom of each of the three second gears being connected to a clamp via a second connecting rod.

[0012] Preferably, a rotating rod is fixedly connected to the upper center of the second gear, and a limiting piece is fixedly connected to the top of the rotating rod. The rotating rod and the limiting piece are slidably connected inside the limiting groove.

[0013] Compared with the prior art, the advantages of this utility model are as follows: By setting a rotating component, this utility model can make the glass instrument both rotate on its own axis and revolve around the sun, which can ensure that each surface can come into contact with hot air, avoiding uneven heat accumulation in some parts. During the rotation of the instrument, moisture is continuously carried to different areas, increasing the chance of moisture coming into contact with hot air. The combination of rotation and revolution helps each surface of the glass instrument to be heated evenly, thereby accelerating the evaporation of moisture, shortening the drying time, and thus increasing the evaporation rate. Especially when the bottle mouth is placed downwards, the moisture is more easily carried away, reducing the possibility of water droplets recondensing inside the glass instrument.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] Reference Figures 1-9 As shown, a novel rotatable airflow drying device for glass instruments includes a drying chamber 1. A door 2 is hinged to the front of the drying chamber 1. A water collection tank 6 is fixedly connected to the bottom of the drying chamber 1. An inclined guide plate 7 is fixedly connected to the upper part of the water collection tank 6. The guide plate 7 is designed with a 15° inclination and uses a superhydrophobic nano-coating to increase the condensate dripping speed. A heating chamber 3 is fixedly connected to the rear of the drying chamber 1 above the water collection tank 6. An axial flow fan 4 is fixedly connected to the rear of the heating chamber 3. Several heating wires 5 are fixedly connected inside the heating chamber 3. A rotating component 9 is installed at the upper part of the drying chamber 1. A control panel (not shown in the figure) is integrated on the drying chamber 1 to control the operation of the components. During drying, the drying temperature should generally be within the range of 40℃-50℃ to promote moisture evaporation without being too high, causing the internal moisture to quickly turn into steam and re-condense. The glass instruments achieve 360° heating without dead angles through a dual-drive mode (revolution + rotation). Compared with traditional single-layer tray drying, this increases the hot air contact area and shortens the drying time.

[0027] Optionally, an observation window is provided on the front side of the door 2 for observation. The observation window is made of double-layer hollow explosion-proof glass and is equipped with an LED lighting system to achieve clear observation while maintaining a constant temperature inside the chamber, reducing the number of times the chamber is opened. A drain pipe 8 is fixedly connected to the lower right side of the drying chamber 1. The end of the drain pipe 8 passes through the right side wall of the drying chamber 1 and is connected to the water collection tank 6. The drain pipe 8 adopts a one-way valve design to prevent exhaust gas from backflowing and polluting the drying environment.

[0028] Furthermore, the rotating assembly 9 includes a fixed disk 901, which is fixedly connected to the inner top wall of the drying oven 1. A connecting disk 902 is fixedly connected to the center of the bottom surface of the fixed disk 901, and a connecting ring 904 is fixedly connected to the outer side of the bottom of the fixed disk 901. An arc-shaped T-shaped limiting groove 905 is formed between the connecting disk 902 and the connecting ring 904. A rotating rod 911 is fixedly connected to the center of the upper part of the second gear 910. A limiting piece 912 is fixedly connected to the top of the rotating rod 911. The rotating rod 911 and the limiting piece 912 are slidably connected inside the limiting groove 905. The arc-shaped T-shaped limiting groove 905, the rotating rod 911, and the limiting piece 912 are designed to have three-point contact, which automatically balances the centrifugal force during the revolution.

[0029] Specifically, a number of first connecting rods 906 are fixedly connected to the bottom of the connecting ring 904, and a gear ring 907 is fixedly connected to the bottom of the connecting ring 904 through the first connecting rods 906. The three-stage gear transmission (first gear 909 → second gear 910 → gear ring 907) forms a differential motion to ensure that the glass instruments maintain a dynamic distance and eliminate the hot air blind spot.

[0030] Specifically, the rotating assembly 9 also includes a servo motor 903, which is fixedly installed on the top of the drying chamber 1. The output end of the servo motor 903 passes through the top wall of the drying chamber 1 and the middle of the connecting plate 902 and is fixedly connected to a drive shaft 908. A first gear 909 is fixedly connected to the bottom of the drive shaft 908. The contact points of the first gear 909, the second gear 910 and the gear ring 907 are all provided with a nano-waterproof coating, which can prevent oxidation and rust in a humid environment, thus avoiding uneven rotation.

[0031] Furthermore, at least three second gears 910 are provided between the first gear 909 and the gear ring 907. The two sides of the second gear 910 mesh with the first gear 909 and the gear ring 907 respectively. The bottom of each of the three second gears 910 is connected to a clamp 914 via a second connecting rod 913. The specific structure and working principle of the clamp 914 can be found in the patent with publication number CN222363521U. This is prior art and will not be elaborated on here. The second connecting rod 913 is connected to one half of the clamp ring, which is the fixed part, while the other part is the movable part used for inserting glass. The clamp 914 is provided with an anti-slip rubber ring, which can prevent scratches on the surface of the glass instrument when clamping it.

[0032] Working principle: First, open the door 2, place the glass instrument bottle with the mouth facing up and fix it in the clamp 914, then close the door 2. Set the temperature and wind speed through the control panel. The axial flow fan 4 draws ambient air into the heating chamber 3, heats it to the set temperature through the heating wire 5, and then distributes it evenly in the drying chamber 1. The servo motor 903 drives the transmission shaft 908 to rotate, thereby driving the first gear 909 to rotate. The second gear 910 meshes with the gear ring 907, driving the three second gears 910 to revolve around the gear ring 907 and rotate around their own axis. The second gears 910 drive the clamp 914 to perform planetary motion through the second connecting rod 913, so that the glass instrument is exposed to wind at multiple angles during rotation. The condensate formed by the hot air contacting the cold glass surface flows into the water collection tank 6 along the guide plate 7 and is discharged out of the chamber through the drain pipe 8, preventing water droplets from flowing back and contaminating the instrument.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
