[0018] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0019] A platinum-carbon catalyst production drying device, such as Figure 1-Figure 4 As shown, it includes a box body 1, a closing door 2, a heating tube 3, a rotating rod 4, a tray 5 and a drying box 6. The front part of the box body 1 is rotatably connected to the closing door 2, and a sealing strip is provided on the edge of the closing door 2. The sealing strip is used to isolate the air inside the box body 1 from the outside of the box body 1, thereby ensuring that the box body 1 has good sealing performance. The upper inner side of the box body 1 is fixedly connected to the heating tube 3, the inner side of the box body 1 is rotatably connected to the rotating rod 4, and the middle part of the rotating rod 4 is fixedly connected to four trays 5, and two drying boxes 6 are provided on the top of each tray 5. The drying boxes 6 are semi-cylinders, and a semi-circular avoidance groove for the rotating rod 4 to pass through is opened in the middle of the opposite side of the drying boxes 6 on each layer of the tray 5.

[0020] Initially, there is no drying box 6 on the tray 5. When the platinum-carbon catalyst needs to be dried, the platinum-carbon catalyst is poured into the drying box 6, the door 2 is opened and closed, the drying box 6 is placed on the tray 5, the door 2 is closed and closed, and the heating tube 3 is started. The heating tube 3 can heat the air inside the box 1, and the hot air can heat and dry the platinum-carbon catalyst. After the platinum-carbon catalyst is heated and dried, the door 2 is opened and closed, and the drying box 6 is taken out from the tray 5. In this way, the drying process of the platinum-carbon catalyst is completed. The platinum-carbon catalyst only contacts the drying box 6. When cleaning the device, only the drying box 6 needs to be cleaned, which is very convenient.

[0021] like Figure 1 and Figure 2 As shown, it also includes an air pump 7, which is fixedly connected to the right side of the box body 1. The air suction end of the air pump 7 is fixedly connected to the upper right side of the box body 1, and the exhaust end of the air pump 7 is fixedly connected to the lower right side of the box body 1. The air suction section and the exhaust end of the air pump 7 both pass through the right side of the box body 1.

[0022] After starting the heating tube 3, start the vacuum fan 7, which draws hot air from the upper inner side of the box 1 through the vacuum end, and then discharges the hot air to the lower inner side of the box 1 from the exhaust end of the vacuum fan 7, so that the hot air in the box 1 circulates continuously to heat the platinum-carbon catalyst, and the platinum-carbon catalyst in the drying box 6 is heated evenly, preventing the platinum-carbon catalyst from showing different degrees of dryness due to different temperatures between the upper and lower parts of the box 1, thereby improving the drying efficiency of the device.

[0023] like Figure 1-Figure 3 As shown, it also includes a cylinder 8, a screw 9 and a nut 10. The cylinder 8 is fixedly connected to the top of the box body 1. The piston rod of the cylinder 8 passes through the top of the box body 1. The screw 9 is fixedly connected to the piston rod of the cylinder 8. The nut 10 is clamped on the top of the rotating rod 4, and the screw 9 and the nut 10 are threadedly connected.

[0024] When drying the platinum-carbon catalyst, start the cylinder 8, so that the piston rod of the cylinder 8 moves downward, driving the screw 9 to move downward and threadedly connected with the nut 10, so that the nut 10 rotates and drives the rotating rod 4 to rotate, and the rotation of the rotating rod 4 drives the tray 5 and the drying box 6 on the tray 5 to rotate, so that the hot air can fully contact the platinum-carbon catalyst, accelerate the drying of the platinum-carbon catalyst, and further improve the drying efficiency of the device.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a guide ring 11 and a window 12. The guide ring 11 is fixedly connected to the upper inner side of the box body 1, and the window 12 is fixedly connected to the left side of the box body 1. The window 12 passes through the left side of the box body 1 and is fixedly connected to the guide ring 11. A notch is provided at the connection between the guide ring 11 and the window 12, and an inclined through groove is provided at the top of the guide ring 11.

[0026] The platinum-carbon catalyst will generate water vapor when drying, and the water vapor will adhere to the inner wall of the box body 1 to form water droplets. The water droplets can flow from the inner wall of the box body 1 to the inclined groove of the guide ring 11, and then flow from the notch of the guide ring 11 to the window 12, and finally flow out of the box body 1 from the window 12. Leading the water vapor in the box body 1 to the outside of the box body 1 can keep the inside of the box body 1 dry, and prevent the water in the platinum-carbon catalyst from being unable to be dried when the humidity of the hot air in the box body 1 is the same as the water content of the platinum-carbon catalyst, thereby further improving the drying efficiency of the device.

[0027] like Figure 2 and Figure 3 As shown, it also includes a guide block 13, a first connecting rod 14 and a second connecting rod 15. The guide block 13 is fixedly connected to the bottom inner side of the box body 1, and a groove is opened on the top of the guide block 13. The bottom end of the rotating rod 4 is slidably connected in the groove of the guide block 13, and the bottom of the rotating rod 4 is rotatably connected to the first connecting rod 14. The other end of the first connecting rod 14 is rotatably connected to the second connecting rod 15, and the other end of the second connecting rod 15 is hinged to the inner wall of the closing door 2.

[0028] When the door 2 is opened and closed, the second connecting rod 15 and the first connecting rod 14 are driven to rotate, and finally the rotating rod 4 is pulled to move forward along the groove of the guide block 13. The rotating rod 4 moves forward and drives the tray 5 and the drying box 6 to move forward and be exposed outside the box body 1. At this time, the drying box 6 can be taken out of the tray 5 or the drying box 6 can be placed on the tray 5. When the door 2 is closed and closed, the second connecting rod 15 and the first connecting rod 14 are driven to rotate, and finally the rotating rod 4 is pushed to move backward along the groove of the guide block 13. The rotating rod 4 moves backward and drives the tray 5 and the drying box 6 to move backward back into the box body 1. The rotating rod 4 is rotated to make the nut 10 engage with the rotating rod 4 to complete the resetting of the rotating rod 4. After the platinum-carbon catalyst is dried, there is still a large amount of high-temperature gas in the box body 1. Exposing the tray 5 and the drying box 6 outside the box body 1 can prevent people from being scalded by the high-temperature gas in the box body 1 when taking out the drying box 6, making it more convenient to take and put the drying box 6.

[0029] like Figure 1 As shown, a door opener 16 is also included. The upper front part of the box body 1 is fixedly connected with the door opener 16, and the connecting arm of the door opener 16 is fixedly connected to the left front part of the closing door 2. When the closing door 2 needs to be opened, the door opener 16 is started, and the door opener 16 can open the closing door 2 and move the rotating rod 4, the tray 5 and the drying box 6 out of the box body 1. Since the rotating rod 4, the tray 5 and the drying box 6 are heavy, it is difficult for people to manually open the closing door 2. The door opener 16 can make the opening and closing of the closing door 2 easier, thereby improving the working efficiency of the device.

[0030] like Figure 3 As shown, it also includes bosses 17, and six bosses 17 are fixedly connected to the top of each tray 5. The drying box 6 is clamped with the tray 5 through the bosses 17 on each tray 5. When the drying box 6 is placed on the tray 5, the bosses 17 can clamp the drying box 6 on the tray 5 to prevent the drying box 6 from being thrown out of the tray 5 when the rotating rod 4 rotates, resulting in drying failure. The bosses 17 can also play a positioning role, making it convenient to place the drying box 6 on the tray 5.
