DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-3 In this embodiment, a metal surface treatment galvanizing drying device includes a drying box 1 and a humidity sensor 25, the humidity sensor 25 is fixedly installed on the inner wall of the drying box 1, a suspended basket 2 is fixedly installed on the inner top wall of the drying box 1, and a plurality of through holes 3 are opened on the left and right sides and the bottom of the suspended basket 2, and an exhaust gas collection mechanism is arranged inside the drying box 1;
[0023] The exhaust collecting mechanism is fixedly mounted on the exhaust hood 4 at the middle of the top of the drying box 1, the exhaust fan 5 is fixedly connected inside the exhaust hood 4, the guide rail 6 is fixedly connected to the outside of the exhaust hood 4, the slide plate 7 is slidably connected to the inside of the guide rail 6, the electric push rod 8 is fixedly connected to the bottom of the guide rail 6, the output shaft of the electric push rod 8 is fixedly connected to a connecting plate 9, the side of the connecting plate close to the guide rail 6 is fixedly connected to the outside of the slide plate 7, the inside of the drying box 1 is fixedly connected to a collecting bucket 10, the inner bottom wall of the drying box 1 is fixedly connected to a slide rail 11, the inner side of the slide rail 11 is slidably connected to a collecting box 12, and the front of the collecting box 12 is fixedly connected to a handle 13, wherein, all water droplets on the outer surface of the workpiece that is continuously blown by hot air until it is dry will first fall into the collecting bucket 10 through the through hole 3, and then be discharged into the inside of the collecting box 12 through the collecting bucket 10, so as to be temporarily stored for centralized cleaning.
[0024] In addition, when the humidity sensor 25 detects that the humidity inside the drying box 1 is too high, the two electric push rods 8 are started at the same time, and the two slide plates 7 are driven away from each other through the connecting plate 10, thereby exposing the opening at the top of the exhaust hood 4. At this time, the exhaust fan 5 is started to quickly exhaust the humid air inside the drying box 1, thereby ensuring the drying effect and avoiding excessive humidity inside the drying box 1.
[0025] It should be noted that when the humidity sensor 25 detects that the humidity inside the drying box 1 has been significantly reduced, the output shafts of the two electric push rods 8 are reset at the same time, so that the two slide plates 7 are close to each other, thereby reclosing the opening at the top of the exhaust hood 4, thereby ensuring the sealing of the drying box 1 and preventing hot air from leaking out.
[0026] Among them, the left and right sides of the drying box 1 are fixedly connected with a hood 14, and the interior of the hood 14 is fixedly connected with an air intake fan 15, an electric heating wire heating tube 16 and an air outlet fan 17. Through the cooperation of the air intake fan 15, the electric heating wire heating tube 16 and the air outlet fan 17, the air in the external environment can be inhaled and heated, and finally the hot air is blown to the position of the suspended basket 2 by convection, so as to perform hot air drying on the workpieces inside the suspended basket 2.
[0027] It should be understood that a grille 18 is fixedly connected to the left and right sides of the hood 14, and a filter 19 is fixedly connected to the bottom of the exhaust hood 4. By providing the grille 18 and the filter 19, the effect of blocking dust and debris is achieved.
[0028] There are two slide plates 7 and two electric push rods 8, and both are relatively distributed on the top of the drying box 1. The bottom of the slide plate 7 is fixedly connected with a sealing gasket 20, which is made of rubber.
[0029] See also Figure 1 and Figure 4The front of the drying box 1 is hinged with a first sealed door 21 and a second sealed door 22, and door handles are welded on the front of the first sealed door 21 and the second sealed door 22. A timer 23 and an alarm 24 are respectively arranged on the front of the first sealed door 21. The timer 23 and the humidity sensor 25 are electrically connected to the alarm 24. By arranging the timer 23 and the alarm 24, the effect of timing the drying time and reminding the staff is achieved.
[0030] It should be noted that there are two warning lights and a sound device on the front of the alarm 24. When the drying time is reached or the humidity inside the drying box 1 is too high, the two warning lights corresponding to different situations will light up respectively, and at the same time, the sound device will emit a beeping sound to remind the staff.
[0031] The working principle of the above embodiment is:
[0032] When in use, the staff first needs to open the first sealed door 21 to expose the interior of the drying box 1, and then neatly arrange the workpieces into the suspended basket 2. When the workpieces are placed, press the timer 23 to start timing, then close the first sealed door 21 and start the air inlet fan 15, the electric heating wire heating tube 16 and the air outlet fan 17, so as to continuously inhale and heat the air in the external environment, and finally blow the hot air to the position of the suspended basket 2 in a convection manner, so as to perform hot air drying on the workpieces in the suspended basket 2. Among them, all water droplets on the outer surface of the workpiece that is continuously blown by the hot air until it is dry will first fall into the collection bucket 10 through the through hole 3, and then through the collection bucket 10 is discharged into the collection box 12 for temporary storage so as to be cleaned together. In addition, when the humidity sensor 25 detects that the humidity inside the drying box 1 is too high, the two electric push rods 8 are started at the same time, and the two slide plates 7 are driven away from each other through the connecting plate 10, so as to expose the opening at the top of the exhaust hood 4. At this time, the exhaust fan 5 is started to quickly exhaust the humid air inside the drying box 1. When the humidity sensor 25 detects that the humidity inside the drying box 1 has been significantly reduced, the output shafts of the two electric push rods 8 are reset at the same time, so that the two slide plates 7 are close to each other, thereby re-closing the opening at the top of the exhaust hood 4, thereby ensuring the sealing of the drying box 1 and preventing hot air from leaking out.
