[0002] Electronic components are components of electronic elements and small electrical machines and instruments. They are often composed of several parts and can be used interchangeably in similar products. They often refer to certain parts of industries such as electrical appliances, radios and instruments, such as capacitors, transistors, hairsprings and springs. Common ones include diodes, etc.

[0003] Ceramic powder needs to be dried before use in order to achieve two purposes: one is to remove moisture, and the other is to increase the strength of the particles. There are many drying methods, and the main industrial applications include hot air drying, infrared drying, spray drying, freeze drying and other types.

[0004] Among them, the hot air drying method in the hot air drying box is fast in drying powder and can be dried continuously in large quantities. However, since it generates hot air for drying, it cannot fully contact the container containing the ceramic powder in all directions to increase the temperature for drying, which can easily cause uneven temperature distribution and affect the drying effect.

[0005] Based on this, it is necessary to propose a powder drying device that can keep the dry hot air in full contact with the container containing the ceramic powder in all directions and maintain a uniform temperature. Utility Model Content

[0027] 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 of 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.

[0028] See also Figure 1-4 , the utility model provides a technical solution: a ceramic powder drying device, comprising: a drying unit and a guide unit;

[0029] The drying unit includes a hot air blower 100, a drying box 110, a receiving box 120, and a material storage box 130;

[0030] An air duct is provided on the side of the hot air blower 100 . The air duct passes through one side of the drying box 110 and is located at the side of the object receiving box 120 . The material storage box is concavely installed inside the object receiving box 120 .

[0031] The hot air from the hot air blower 100 can be transported to the drying box 110 through the air duct to keep the inside of the drying box 110 dry, so as to keep the receiving box 120 dry, and further dry the material box 130 so that the ceramic powder in the material box can be dried.

[0032] See also Figure 2 , Figure 3 The guide unit includes an air guide groove 200, a coil spring 210, a flip plate 220, an air guide port 230, an air guide plate 231, and an exhaust port 2311. The air guide groove 200 passes through the object receiving box 120 in the direction of the air guide duct. Through the air guide groove 200, the air guide duct can blow hot air into the object receiving box 120, so that the hot air directly contacts the material box 130.

[0033] The coil spring 210 is symmetrically installed on the inner wall of the air guide groove 200, and the flip plate 220 is connected to the coil spring 210 in the air guide groove 200. The coil spring 210 and the flip plate 220 can seal the air guide groove 200, and the flip plate 220 can block the hot air so that the hot air flows upward. The air guide port 230 passes through the upper and lower partitions between the two air guide grooves 200, and the exhaust port 2311 passes through the air guide plate 231 installed in the air guide port 230.

[0034] The air guide plate 231 is arranged in an arc shape, and the lower end of the air guide plate 231 contacts the top of the flip plate 220 .

[0035] See also Figure 3 The bottom of the air guide plate 231 contacts the top of the flip plate 220, which can reduce the outflow of wind from between the two structures, and can maximize the hot air entering initially and the hot air being guided to form a stable hot air retention area, and maintain the temperature between the flip plate 220 and the air guide plate 231. The hot air contacts the air guide plate 231 from the air guide port 230 and blocks the air flow in the air guide slot 200 from the air inlet direction, so that the wind stays near the flip plate 220 of the material box 130 to continuously dry the material and perform hot air drying. The bottom of the flip plate 220 is above the exhaust port 2311, and part of the hot air will pass through the exhaust port 2311 and move upward to dry and heat the flip plate 220 above it, reduce its heat absorption, and maintain its temperature stability.

[0036] For details, see Figure 2 , Figure 3 The flip plate 220 is tilted inside the air guide groove 200. When no external force is applied to the flip plate 220, the end of the flip plate 220 close to the material box 130 is lower, and the end of the flip plate 220 away from the material box 130 is higher, wherein the coil spring 210 is arranged on the side of the flip plate 220 close to the lower end of the material box 130. When the flip plate 220 is not subjected to force, the wind will be guided to move obliquely upward when it flows to the flip plate 220. When the flip plate 220 is subjected to downward pressure, the elasticity of the coil spring 210 is overcome, and the side of the air guide groove 200 can be opened, and the material box 130 can be placed in or taken out of the receiving box 120.

[0037] See also Figure 3 Further preferably, there are a plurality of air outlets 2311 evenly arranged on the air guide plate 231 , and the top of the air guide plate 231 and the bottom of the flip plate 220 are chamfered.

[0038] The hot air can pass through the air guide plate 231 and move upward through the plurality of air outlets 2311 , and can stay between the air guide plate 231 and the flip plate 220 through the gap between the air guide plate 231 and the flip plate 220 .

[0039] See also Figure 4 Further preferably, the lower surface of the drying box 110 is connected to the guide rail 300 by bolts, and the storage box 120 is slidably connected to the guide rail 300 by a slider 310 .

[0040] The guide rail 300 and the slider 310 facilitate the movement of the object receiving box 120 into and out of the drying box 110 , and facilitate the dragging out of the object receiving box 120 for cleaning and removal of powder residues.
