Description

Technical Field

[0001] This utility model relates to the field of drying device technology, and in particular to an experimental drying device. Background Technology

[0002] When conducting experiments, a large number of test tubes are needed. Test tubes are used as reaction containers for small amounts of reagents and are used at room temperature or when heated. After use, test tubes are usually cleaned with pure water and then dried using a drying device.

[0003] To this end, patent CN219368192U discloses an experimental drying device, relating to the field of drying devices. The device includes a main body with a disassembly assembly inside. The disassembly assembly includes a base plate with an air chamber inside. A sliding sleeve is connected to the base plate, and a guide block is fixed to the sliding sleeve. A telescopic rod connects the sliding sleeve and the base plate, and a tension spring is sleeved on the outside of the telescopic rod. A test tube rack is fixed to the top of the base plate. This invention, through the disassembly assembly, allows for direct transfer of the entire test tube rack by disassembling the base plate, eliminating the original test tube transfer step. The base plate can be accurately delivered into the main body via a guide rail corresponding to the limiting block. During this process, the guide block slides under the action of the top block, causing the sliding sleeve to slide out from inside the base plate. When the base plate is fully inside the main body, the sliding sleeve fits snugly against the main body, thus connecting the air chamber with the cavity containing the fan. This design simplifies the use of the drying device and saves test tube transfer time.

[0004] Existing experimental drying equipment is not convenient for positioning test tubes during use, which causes the test tubes to shake easily during drying. During the shaking, the test tubes are prone to collision with the drying rack and be damaged. Utility Model Content

[0005] The purpose of this invention is to provide an experimental drying device to solve the defect of an existing experimental drying device that is inconvenient for positioning test tubes.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an experimental drying device, including a drying chamber, with ventilation openings installed on both sides of the drying chamber, and dustproof nets installed on the ventilation openings; a bottom plate installed inside the drying chamber, with drying racks evenly installed on the top of the bottom plate; a water-absorbing structure provided on the upper surface of the bottom plate; a fan installed on one side inside the drying chamber, with an air outlet installed on one side of the fan; a heating plate installed between the air outlet and the fan; and a positioning mechanism provided at the top of the drying chamber, which can position the test tubes on the drying racks. The clamping mechanism is used to achieve positioning. It includes a drive cylinder, a lifting frame, a positioning plate, a guide rod, a support frame, positioning grooves, and elastic rubber pads. The support frame is installed at the top inside the drying oven. The drive cylinder is mounted on the support frame, and the output end of the drive cylinder is fitted with the lifting frame. Guide rods are symmetrically mounted on the bottom end of the lifting frame, and a positioning plate is mounted on the bottom end of the guide rods. Positioning grooves are evenly spaced on the positioning plate, and elastic rubber pads are installed on the inner walls of each positioning groove. Cleaning structures for removing dust from the dust filter are located on both sides of the positioning mechanism.

[0007] Preferably, the cleaning structure includes connecting rods and brushes, with the connecting rods installed on both sides of the lifting frame and brushes mounted on each connecting rod.

[0008] Preferably, the length of the brush is greater than the width of the dustproof net.

[0009] Preferably, the base plate is a pull-out structure.

[0010] Preferably, the water-absorbing structure includes a locking block, a locking groove, and a water-absorbing cotton pad. The locking block is evenly installed at both ends of the upper surface of the base plate, and the water-absorbing cotton pad is installed on the upper surface of the base plate. The bottom ends of the water-absorbing cotton pad are evenly provided with locking grooves that cooperate with the locking block.

[0011] Preferably, the card block and the card slot form an engaging structure.

[0012] Preferably, the positioning groove and the elastic rubber pad have a structure with a small opening at the top and a large opening at the bottom.

[0013] The experimental drying apparatus provided by this utility model has the following advantages:

[0014] The positioning mechanism clamps the test tubes on the drying rack, thus positioning them and preventing them from shaking during drying. At the same time, the cleaning structure cleans the dust screen to prevent dust from clogging it, and the water absorption structure absorbs any water dripping from the test tubes, preventing water from flowing around and contaminating the drying oven.

[0015] The positioning mechanism drives the cylinder to move the lifting frame down, and the guide rod moves the positioning plate down until the test tube enters the positioning groove and contacts the elastic rubber pad. The elastic rubber pad can clamp the test tube to achieve the purpose of positioning it and prevent the test tube from shaking during drying.

[0016] With the cleaning structure in place, as the lifting frame moves downward, the connecting rod drives the brush downward. During the downward movement, the brush can sweep away the dust adhering to the dust screen, thus achieving the purpose of cleaning and preventing the dust screen from becoming clogged.

[0017] With its designed absorbent structure, the absorbent pad can absorb the water dripping from the test tubes, preventing water from flowing everywhere and contaminating the drying oven. Moving the absorbent pad upwards will cause the locking block to retract from the slot, allowing the absorbent pad to be removed for replacement. Attached Figure Description

The positioning groove 1106 and the elastic rubber pad 1107 have a structure with a small opening at the top and a large opening at the bottom to position test tubes of different sizes.

[0028] Place the test tubes to be dried on the drying rack 10, push the base plate 7 into the drying chamber 2, start the drive cylinder 1101, the drive cylinder 1101 causes the lifting frame 1102 to move down, the guide rod 1104 drives the positioning plate 1103 to move down until the test tube enters the positioning groove 1106 and contacts the elastic rubber pad 1107. The elastic rubber pad 1107 can clamp the test tube and position it to prevent the test tube from shaking during drying. Start the fan 4, and the hot air heated by the heating plate 5 can be blown from the air outlet 6 through the air blowing hole on the drying rack 10 to dry the test tube.

[0029] Reference Figure 1 , Figure 2 and Figure 3 As shown, the cleaning structure 1 for cleaning dust on the dustproof net 3 is set on both sides of the positioning mechanism 11.
