Description

Technical Field

[0001] This utility model relates to the field of cleaning and drying technology, and specifically to a low-power internal circulation drying device. Background Technology

[0002] Currently, during the processing of workpieces, cleaning fluid is often used to clean them. After cleaning, the cleaning fluid remains on the workpiece surface, which can easily cause corrosion and needs to be removed. For example, the cleaning fluid air-cutting device disclosed in prior art 202320248291.0 uses a high-pressure nozzle at the top to cut the cleaning fluid on the workpiece surface and remove it. However, this method is not only inefficient, but also makes it difficult to completely remove the cleaning fluid from the workpiece surface closer to the bottom due to the weakened air-cutting force and the obstruction of the upper workpiece. This can easily leave residue on the workpiece, causing corrosion and damage, and shortening the service life of the workpiece. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a low-power internal circulation drying device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a low-power internal circulation drying device, comprising a drying chamber with a top opening, heating components and a circulating fan respectively disposed on the sides of the drying chamber, a cover plate movably disposed on the top of the drying chamber, and a driving component for driving the cover plate to open or close the top opening of the drying chamber.

[0007] Preferably, multiple heaters are provided and are vertically arranged inside the heating box, and are placed side by side at intervals along the exhaust direction of the circulating fan.

[0008] Preferably, the top opening of the drying oven is provided with oppositely placed sliding grooves on both sides; the cover plate is slidably disposed in the sliding grooves on both sides.

[0009] Preferably, rollers are provided between the cover plate and the slide groove, and at least two rollers are provided between the cover plate and each side slide groove.

[0010] Preferably, the drive assembly is driven by a cylinder.

[0011] Preferably, the drying oven is provided with a support frame placed at a distance from the bottom of the drying oven; the support frame is used to place a fixture containing the workpiece.

[0012] Preferably, the heating components and the circulating fan are located on opposite or adjacent sides of the drying chamber.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] Appendix Figure 2 This is a cross-sectional view of the low-power internal circulation drying device described in this utility model;

[0018] Appendix Figure 3 for Figure 2 Enlarged view of a portion of point A in the middle.

[0019] The components include: 1. Drying oven; 11. Opening; 12. Slide rail; 2. Heating assembly; 21. Heating chamber; 22. Heater; 23. Temperature sensor; 3. Circulating fan; 31. Exhaust port; 4. Cover plate; 5. Cylinder; 6. Pipeline; 7. Roller; 8. Support frame; 9. Fixture. Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Appendix Figure 1 The low-power internal circulation drying device of this utility model includes a drying chamber 1 with a top opening 11, a heating component 2 and a circulating fan 3 respectively disposed on the side of the drying chamber 1, a cover plate 4 movably disposed on the top of the drying chamber 1, and a driving component for driving the cover plate 4 to open or close the top opening 11 of the drying chamber 1.

[0022] The air intake of the circulating fan 3 is connected to the drying chamber 1, and its exhaust port 31 is connected to the heating component 2 through the pipe 6; the heating component 2 is also connected to the drying chamber 1.

[0023] During operation: The workpiece is placed in the drying chamber 1 by manual or automated equipment, and then the drying device is started. First, the cover plate 4 closes the opening 11 at the top of the drying chamber 1 through the drive component, and then the heating component 2 heats it. At the same time, the circulating fan 3 enables the hot air to circulate internally between the drying chamber 1 and the heating component 2, which greatly reduces the loss of heat exhaust. It has the advantages of high drying efficiency and low power consumption.

[0024] Furthermore, such as Figure 2 As shown, the heating assembly 2 includes a heating chamber 21 connected to the drying chamber 1, a heater 22 disposed in the heating chamber 21, and a temperature sensor 23 disposed in the heating chamber 21; wherein the heater 22 is heating, and the temperature sensor 23 can monitor the temperature inside the heating chamber 21 in real time.

[0025] Furthermore, the heating component 2 is also equipped with an energy-saving control mode. Before the drying process is completed, the heating component 2 will be turned off in advance, and the residual heat will be used to achieve internal circulation. This not only saves energy but also accelerates the cooling of the heating component 2 and improves its overall service life.

[0026] Furthermore, the heating component 2 is also equipped with a triple over-temperature protection control system, namely PID temperature protection, PLC over-temperature power-off, and mechanical over-temperature protector, to achieve three-fold safety protection for the drying device. Since it is existing technology, its structure will not be described in detail.

[0027] Furthermore, multiple heaters 22 are provided and are vertically arranged inside the heating box 21, and are placed side by side at intervals along the exhaust direction of the circulating fan 3, so that the air discharged by the circulating fan 3 can fully contact the multiple heaters 22 and discharge the hot air into the drying box 1.

[0028] Furthermore, such as Figure 3 As shown, the top opening 11 of the drying oven 1 is provided with oppositely placed sliding grooves 12 on both sides; the two sides of the cover plate 4 are slidably disposed in the sliding grooves 12; in this embodiment, the cover plate 4 is slidably moved to facilitate opening the cover plate 4. Of course, a flip-top structure can also be used, as long as the cover plate 4 can be opened or closed automatically.

[0029] Furthermore, such as Figure 3 As shown, rollers 7 are provided between the cover plate 4 and the slide groove 12, and at least two rollers 7 are provided between the cover plate 4 and each side slide groove 12, so that the cover plate 4 can be opened and closed more smoothly and its service life can be improved.

[0030] Furthermore, the drive assembly is driven by a cylinder 5, but it can also be driven by belt drive, gear and rack drive, etc.

[0031] Furthermore, such as Figure 2As shown, the drying oven 1 is provided with a support frame 8 placed at a distance from the bottom of the drying oven 1; the support frame 8 is used to place the fixture 9 containing the workpiece; when the cleaned workpiece is placed in the drying oven 1 through the fixture 9, the cleaning liquid on the surface of the workpiece will drip down and collect at the bottom of the drying oven 1. Since the support frame 8 is placed at a distance from the bottom of the drying oven 1, it can effectively prevent the cleaning liquid at the bottom of the drying oven 1 from contacting the workpiece at the bottom of the fixture 9, thus preventing it from drying completely.

[0032] Furthermore, the heating assembly 2 and the circulating fan 3 are located on opposite or adjacent sides of the drying chamber 1; in this embodiment, as... Figure 1 As shown, the heating element 2 and the circulating fan 3 are located on adjacent sides of the drying chamber 1, which facilitates the connection of the heating element 2 and the circulating fan 3 through the pipe 6. At the same time, when the end cover is opened, it is located directly above the circulating fan 3, making the whole structure more compact.

[0033] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
