[0001] This utility model relates to the field of magnesium alloy technology, and in particular to a drying structure of a cleaning device for magnesium alloy passivation. Background Technology

[0002] Magnesium alloys are alloys composed of magnesium as the base and other elements. They are characterized by low density, high strength, high elastic modulus, good heat dissipation, good shock absorption, greater impact load capacity than aluminum alloys, and good resistance to corrosion by organic matter and alkalis. The main alloying elements are aluminum, zinc, manganese, cerium, thorium, and small amounts of zirconium or cadmium. The most widely used are magnesium-aluminum alloys, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. They are mainly used in aviation, aerospace, transportation, chemical, rocket and other industrial sectors.

[0003] Chinese patent document CN216880576U discloses a cleaning device with a dehumidification and drying structure for magnesium alloy passivation, belonging to the field of magnesium alloy technology. It aims to solve the problems of solution splashing when removing the material during drying and the difficulty in removing stubborn stains from some material surfaces. The cleaning device for magnesium alloy passivation with a dehumidification and drying structure includes a housing and a reciprocating mechanism movably disposed within the housing. It also includes a rotating mechanism and a drying mechanism disposed within the housing. The rotating mechanism includes a rotating component disposed on one outer wall of the housing, and the drying component is disposed on the rotating component. However, this cleaning device for magnesium alloy passivation has shortcomings. Although it can dry magnesium alloy plates, it has limitations. The design cannot quickly dry all surfaces of the magnesium alloy plate. Furthermore, the direction of the warm air output is not adjustable, which is not conducive to quickly drying the side wall of the magnesium alloy plate near the cleaning liquid. Its drying effect is poor and its efficiency is low.

[0004] Therefore, in order to solve such problems, we propose a drying structure for a cleaning device for magnesium alloy passivation. Utility Model Content

[0023] Reference Figure 1-5 This utility model provides an embodiment of a drying structure for a magnesium alloy passivation cleaning device, comprising a housing 1, a cleaning tank 11 fixedly connected to the bottom wall of the housing 1, a first electric push rod 12 fixedly connected to the bottom wall of the housing 1, the first electric push rod 12 being located between the outer wall of the cleaning tank 11 and the inner wall of the housing 1, a mounting plate 13 fixedly connected to the output end of the first electric push rod 12, a clamping assembly 3 provided at the lower end of the mounting plate 13, the clamping assembly 3 including a clamp 31, the clamp 31 being fixedly connected to the lower end of the mounting plate 13, a magnesium alloy plate 32 fixedly connected to the inner wall of the clamp 31, the magnesium alloy plate 32 being located directly above the cleaning tank 11, and the upper end of the housing 1. A heater 14 is fixedly connected, and an air outlet 15 is fixedly connected to the output end of the heater 14. A connecting hose 16 is fixedly and sealed to the lower end of the air outlet 15. A second electric push rod 2 is fixedly connected to the upper end of the housing 1. A double-tooth rack 21 is fixedly connected to the output end of the second electric push rod 2. Gears 22 are meshed with each other on the side wall of the double-tooth rack 21. A rotating shaft 23 is fixedly connected to one end of each gear 22. An annular air guide duct 24 is fixedly connected to the side wall of the rotating shaft 23. The side wall of the annular air guide duct 24 near the inner top wall of the housing 1 is sealed and fixedly connected to the connecting hose 16. Several air outlets 25 are sealed and fixedly connected to the side wall of the annular air guide duct 24 near the inner bottom wall of the housing 1.

[0024] This setup works by activating the first electric push rod 12, which causes the mounting plate 13 to move vertically upwards. The mounting plate 13 then moves the clamping assembly 3 vertically upwards, causing the magnesium alloy plate 32 to move vertically upwards out of the cleaning chamber 11. Next, the heater 14 is activated, sending hot air into the outlet duct 15. The outlet duct 15 then sends the hot air into the annular air guide duct 24 via the connecting hose 16. The annular air guide duct 24 then outputs the warm air to the surface of the magnesium alloy plate 32 through the air outlet 25, thus drying the cleaned magnesium alloy plate 32. Alternatively, the second electric push rod 2 can be activated, causing the double-toothed rack 21 to move vertically. The double-toothed rack 21 drives two gears 22 to rotate in opposite directions. These gears, through the rotating shaft 23, drive the annular air guide duct 24 to rotate, which in turn drives the air outlet 25 to change the direction of the warm air output, increasing cleaning efficiency.

[0025] The cleaning tank 11 has a mounting groove 111 on its side wall, a first sliding groove 112 and a second sliding groove 113 on its upper end. A servo motor 17 is installed inside the cleaning tank 11 and is fixedly connected to the bottom wall of the mounting groove 111. A bidirectional threaded rod 171 is fixedly connected to the output end of the servo motor 17. A first slider 172 is threadedly connected to the side wall of the bidirectional threaded rod 171 and is slidably connected to the first sliding groove 112. A mounting post 173 is fixedly connected to the side wall of the first slider 172, and a rubber scraper is fixedly connected to the side wall of the mounting post 173. 18. The end of the mounting post 173 away from the first slider 172 is fixedly connected to the second slider 174. The second slider 174 is slidably connected to the second slide groove 113. By starting the servo motor 17, the servo motor 17 drives the bidirectional threaded rod 171 to rotate, which in turn drives the first slider 172 to slide in the first slide groove 112. This causes the first slider 172 to move the rubber scraper 18 directly above the magnesium alloy plate 32 via the mounting post 173. Then, as the magnesium alloy plate 32 is removed from the cleaning tank 11, the rubber scraper 18 scrapes off the cleaning fluid from the side wall of the magnesium alloy plate 32.

[0026] The distance between the two annular air ducts 24 is greater than the width of the mounting plate 13. This is to prevent the mounting plate 13 from colliding with the annular air ducts 24 when it is raised. Secondly, it helps to increase the drying area of ​​the magnesium alloy plate 32 by the warm air output from the air outlet 25.

[0027] The mounting plate 13 is T-shaped. Even when the cleaning liquid in the cleaning tank 11 is not flush with the upper surface of the cleaning tank 11, the magnesium alloy plate 32 can still be fully immersed in the cleaning liquid, which helps to reduce the use of cleaning liquid and lower cleaning costs.

[0028] The rubber scraper 18 is at a 45° angle to the horizontal plane to prevent the magnesium alloy plate 32 from getting stuck when it rises vertically, thus increasing the smoothness of the structure's operation.

[0029] Both rubber scrapers 18 have beveled ends at their adjacent ends to increase the contact area between the rubber scrapers 18 and the magnesium alloy plate 32, thereby increasing the removal effect of the cleaning fluid on the surface of the magnesium alloy plate 32.

[0030] Working principle: First, by starting the servo motor 17, the servo motor 17 drives the bidirectional threaded rod 171 to rotate. The bidirectional threaded rod 171 drives the first slider 172 to slide within the first slide groove 112. The first slider 172, through the mounting post 173, drives the rubber scraper 18 to move directly above the magnesium alloy plate 32. By starting the first electric push rod 12, the first electric push rod 12 drives the mounting plate 13 to move vertically upward. The mounting plate 13 drives the clamping assembly 3 to move vertically upward, and the magnesium alloy plate 32 moves vertically upward out of the cleaning box 11. At the same time, the rubber scraper 18 scrapes off the cleaning fluid from the side wall of the magnesium alloy plate 32. Then, the heater 14 is started, and the heater 14 inputs hot air into the air outlet duct 15. The air outlet 15 introduces hot air into the annular air guide 24 through the connecting hose 16. Then, the annular air guide 24 outputs warm air to the surface of the magnesium alloy plate 32 through the air outlet 25, thereby drying the cleaned magnesium alloy plate 32. Next, the second electric push rod 2 can be activated. The second electric push rod 2 drives the double tooth rack 21 to move vertically in a straight line. The double tooth rack 21 drives two gears 22 to rotate, and the two gears 22 rotate in opposite directions. The two gears 22 drive the annular air guide 24 to rotate through the rotating shaft 23, thereby changing the direction of the warm air output through the air outlet 25, and quickly drying the side wall of the magnesium alloy plate 32 near the cleaning liquid.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
