Description

Technical Field

[0001] The present application relates to a test equipment drying technology, and in particular to a test tube drying device. Background Art

[0002] After use, the test tube can be used again after cleaning and wiping or drying. At present, in the laboratory, a test tube rack with a plurality of support rods in the top array is generally used to support the test tube to be dried. Specifically, the test tube is inverted on these support rods, the support rods are hollow inside and have vents along the sides, and the test tube is dried by passing hot air into the support rods. In this way, since the position of each vent is fixed, the inside of the test tube facing the vent position will be dried first, and then the drying will spread to other areas, that is, some areas are mainly dried by convection, and some areas are dried by heat conduction and convection combined, and the drying efficiency can be further improved. In some schemes, the rotation operation of the test tube is added on this basis to improve the drying efficiency, but since the ventilation position is fixed, the effect improvement brought by the rotation is not obvious. Utility Model Content

[0003] In order to solve the deficiencies of the above-mentioned prior art, the present application provides a test tube drying device, which can realize continuous adjustment of the position of the vent holes, so that the inner wall of the test tube can be evenly affected by the hot air discharged from the vent holes at various positions during the drying process, thereby improving the drying efficiency.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

The rotating shaft of one of the pulleys is connected to an output shaft of a motor. A driving gear is meshed with the tooth portion of at least one rotating sleeve.

[0010] The beneficial effects of the utility model are:

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0017] The present application embodiment provides a test tube drying device, such as Figure 1 and Figure 4 As shown, it includes a box body 1, a plurality of conical bases 2, a plurality of rotating sleeves 3, etc. The box body 1 is hollow inside and is used to set an air intake pipe 21 and a driving mechanism, etc. The conical bases 2 are arranged in an array on the top surface of the box body 1.

[0018] like Figure 2 As shown, the top surface of the conical base 2 is provided with a guide rod 24, a vent hole 22, and a matching ring 23. The vent hole 22 penetrates downward and is connected to the air inlet pipe 21 provided on the bottom surface of the box body 1. Figure 4There are multiple vent holes 22 distributed in the area between the matching ring 23 and the guide rod 24. A support head 25 is detachably mounted on the top of the guide rod 24 to support the test tube 4.

[0019] The number of rotating sleeves 3 is the same as that of the conical base 2. Figure 3 As shown, the rotating sleeve 3 is a hollow cylindrical structure with openings at both ends, and is sleeved on the guide rod 24 when used. Figure 1 and Figure 4 As shown, after sleeve installation, one end is matched with the bottom of the support head 25, and the other end is matched with the top surface of the conical base 2. Specifically, the rotating sleeve 3 is installed first, and then the support head 25 is installed. After installation, the inner wall of the rotating sleeve 3 is rotated and matched with the outer wall of the matching ring 23.

[0020] like Figure 3 As shown, multiple rows of spirally arranged air outlet holes 30 are provided through the inner and outer walls of the rotating sleeve 3. Preferably, each air outlet hole 30 covers a different height, and the height refers to the distance from the other end to the one end of the rotating sleeve 3 along the axis of the rotating sleeve 3; and through all the air outlet holes 30, it is ensured that the projection collection of all the air outlet holes 30 toward the axis of the rotating sleeve 3 can cover the entire area from the other end to the one end of the axis of the rotating sleeve 3. The outer periphery of the other end of the rotating sleeve 3 is provided with a tooth portion 31, which can be connected to a driving mechanism, and the driving mechanism acts on the tooth portion 31 to drive the rotating sleeve 3 to rotate.

[0021] When in use, the rotating sleeve 3 is first installed on the guide rod 24, and then the support head 25 is installed on the top of each guide rod 24, and each air inlet pipe 21 is connected to the hot air supply channel to receive and introduce hot air into the device, and then the test tubes 4 to be dried are placed on the support head 25. After the test tubes 4 are placed, the driving mechanism is turned on to rotate the rotating sleeve 3, and the hot air enters the area between the rotating sleeve 3 and the guide rod 24 through the air inlet pipe 21 and the air vent 22, and then is sent to the test tube 4 through the spirally arranged air outlet holes 30 to dry the inner wall of the test tube 4. Since the rotating sleeve 3 is rotating and the air outlet holes 30 thereon are arranged in a spiral array, the air flow enters the area between the test tube 4 and the outer wall of the rotating sleeve 3, and is kept relatively uniform at different positions. The inner wall of the test tube 4 is affected by the hot air directly corresponding to the air outlet holes 30 in different directions along the axis, which improves the convective heat transfer effect and is more conducive to drying. Furthermore, in practical applications, the coverage effect of the convection effect on different positions can be made more ideal by adjusting the rotation speed of the rotating sleeve 3. Specifically, since the air outlet holes 30 are arranged in a spiral array, the airflow can form a rotating upward flow after being rotated and sent out, and can act on the top of the test tube 4, ensuring that the entire inner wall of the test tube 4 can be affected.

[0022] Preferably, in order to ensure that the test tube 4 is mainly supported by the support head 25 after being placed and supported, and does not contact the rotating sleeve 3 and maintains a spacing to provide airflow circulation space, the maximum outer diameter of the support head 25 can be larger than the outer diameter of the rotating sleeve 3, so that when the support and the device are started, the test tube 4 will not rotate with the rotating sleeve 3. Among them, after the test tube 4 is placed, the downward tube mouth of the test tube 4 is higher than the bottom end of the rotating sleeve 3.

[0023] In the above embodiment, the matching ring 23 cooperates with the rotating sleeve 3 to provide rotation limitation for the rotation of the rotating sleeve 3, and the lower part of the rotating sleeve 3 covers the matching ring 23, which also prevents the test tube 4 with water droplets remaining on the inner wall from dripping into the matching ring 23 and affecting the air intake channel after being placed. At the same time, the setting of the conical base 2 can also cooperate with the dripping water to discharge the water to the outer peripheral side.

[0024] As one of the specific implementation forms of the driving mechanism, Figure 1 and Figure 4 As shown, the driving mechanism includes a plurality of driving gears 32, the rotating shaft of each driving gear 32 passes through the bottom surface of the box body 1 and is connected to a pulley 33, and the plurality of pulleys 33 are connected by a synchronous belt 34, wherein the rotating shaft of one pulley 33 is connected to the output shaft of a motor 35, and a driving gear 32 is meshed with at least one tooth portion 31 of the rotating sleeve 3, that is, a driving gear 32 can be configured for each tooth portion 31, and it is also possible to consider saving power and simplifying the structure, and configure a meshing driving gear 32 for 2, 3 or 4 tooth portions 31, as shown in FIG. Figure 1 As shown, a driving gear 32 is meshed with the teeth 31 of two rotating sleeves 3. The motor 35 starts to drive the pulley 33 connected to it and other pulleys 33 driven by the synchronous belt 34 to rotate, so as to rotate each driving gear 32, thereby realizing the effect on each tooth 31, and achieving the purpose of rotating the rotating sleeve 3. In terms of the configured power source, only one motor is needed to achieve it.

[0025] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
