Description

Technical Field

[0001] This invention relates to the field of desiccant treatment technology, and more specifically to a silica gel desiccant activation device. Background Technology

[0002] Desiccants are substances that can remove moisture from damp materials. They are generally divided into chemical desiccants and physical desiccants. Chemical desiccants include calcium sulfate and calcium chloride, which dry by combining with water to form hydrates. Physical desiccants include silica gel and activated alumina, which dry by physically adsorbing water. Among them, silica gel desiccants have become the preferred material in the field of moisture protection due to their non-toxic, high-efficiency and renewable characteristics. The weight increase of silica gel desiccants after absorbing moisture is about 30% to 40%, and the specific value is affected by environmental conditions and silica gel type.

[0003] Users can periodically weigh the silica gel desiccant during use. When its weight increases to the specified range, it needs to be replaced with a new silica gel desiccant in time. Then, the replaced silica gel desiccant can be sun-dried or high-temperature dried to activate the silica gel desiccant after it has absorbed moisture, thus achieving the reuse of silica gel desiccant.

[0004] Among the commonly used silica gel desiccant activation methods, equipment suitable for drying is relatively rare in daily life. Therefore, in household environments, silica gel desiccant can mostly only be activated by sun exposure. However, the current standard for judging whether silica gel desiccant has been activated is the measurement of its weight. The activation effect produced by sun exposure is affected by the weather and is not constant. Thus, users need to frequently weigh the silica gel desiccant during the activation process, which is extremely complicated. In view of this, the present invention proposes a silica gel desiccant activation device. Summary of the Invention

A ball seat 202 is coaxially fixed in the middle of the bottom surface of the drying tray 201. The ball seat 202 is a two-thirds sphere structure. A rotating ball 203 is coaxially rotatably connected inside the ball seat 202. A fixing rod 204 is coaxially fixed in the bottom surface of the rotating ball 203. The circular cavity 103... An internal screening mechanism 300 is provided to select the activated silica gel desiccant. The screening mechanism 300 includes a rotating shaft 301, which is a ring structure and is coaxially rotatably connected to the circular cavity 103. A connecting shaft 205 is sleeved on the outside of the fixing rod 204. The lower end of the fixing rod 204 passes through the interior of the rotating shaft 301 and extends to the lower part of the circular cavity 103. The lower end of the fixing rod 204 is coaxially fixedly connected to the bottom surface of the circular cavity 103. Multiple buffer grooves 2011 are evenly opened on the top surface of the drying tray 201 to prevent the silica gel desiccant particles from being too concentrated.

[0069] like Figure 2 , Figure 3 , Figure 7As shown, an exhaust fan 302 is coaxially fixedly connected to the middle of the rotating shaft 301. An air outlet 303 is provided on the top surface of the circular cavity 103 away from the discharge port 102. An air inlet 308 is provided on the bottom surface of the circular cavity 103 opposite to the discharge port 102. The air inlet 308 is U-shaped. A vertical groove 304 is provided on the top surface of the air inlet 308 opposite to the discharge port 102. Multiple through-holes 305 are evenly provided on the upper end of the inner wall of the vertical groove 304 near the receiving groove 101. The size of the through-holes 305 is slightly larger than that of the activated silicon. The desiccant has a through-hole 305 connecting the upper part of the storage trough 101 and the vertical trough 304. The top surface of the through-hole 305 is set with a rounded corner structure on the side near the storage trough 101. The middle part of the vertical trough 304 is connected to the discharge port 102. A filter plate 307 is fixedly installed in the middle part of the vertical trough 304 relative to the lower part of the discharge port 102. The bottom surface of the filter plate 307 and the discharge port 102 are both set with an inclined structure. A partition plate 306 is slidably provided between the through-hole (305) and the vertical trough (304), and between the vertical trough (304) and the discharge port (102). Specifically, a first partition 3061 is slidably connected to the middle of multiple through-holes 305 in the interlayer between the storage groove 101 and the vertical groove 304. A pressing plate 3064 is fixedly provided at the lower end of the side wall of the first partition 3061 near the storage groove 101. The pressing plate 3064 is slidably connected to the outer shell 100. Multiple supporting springs 3065 are fixed between the bottom surface of the pressing plate 3064 and the inner wall of the outer shell 100. The top surface of the pressing plate 3064 is pressed and contacted with the bottom edge of the drying tray 201. A second partition 3062 is slidably connected to the top surface of the discharge port 102. The second partition 3062 is connected and fixed to the two ends of the first partition 3061 by a connecting rod 3063. In this embodiment, the connecting rod 3061 has an L-shaped structure and is slidably connected to the outer shell 100.

[0070] like Figure 4 , Figures 7-10As shown, the drying mechanism 200 and the screening mechanism 300 are driven by the drive mechanism 400. The drive mechanism 400 drives the drying tray 201 to rotate at an incline and drives the screening mechanism 300 to rotate. The drive mechanism 400 includes a turntable 401, which is coaxially and fixedly connected to the upper end of the rotating shaft 301 and rotatably connected to the outer casing 100. A connecting shaft 205 is provided above the turntable 401. The connecting shaft 205 has a ring structure. A disc 206 is coaxially and fixedly connected to the upper end of the connecting shaft 205. A drive rod 207 is fixedly provided on one edge of the top surface of the disc 206. The upper end of the drive rod 207 has a hemispherical structure and slides in contact with the bottom surface of the drying tray 201. Both the connecting shaft 205 and the disc 206 rotate with the outer casing 100. The drive disk 406 is coaxially fixedly connected to the lower end of the connecting shaft 205. A circular groove 104 is coaxially formed inside the outer shell 100 relative to the position of the drive disk 406. The outer wall of the drive disk 406 has a ring-shaped structure with multiple extrusion grooves 4061 at equal intervals. The inner wall of the extrusion grooves 4061 has an L-shaped structure. An extrusion rod 405 is slidably connected to one side of the top surface of the turntable 401 and is in extrusion contact with the extrusion grooves 4061. A compression spring 408 is provided between the extrusion rod 405 and the turntable 401. The compression spring 408 extends and retracts along the radial direction of the turntable 401, so that the extrusion rod 405 can move away from or close to the extrusion grooves 4061. When it is close to the extrusion grooves 4061, it locks the extrusion grooves 4061, causing the connecting shaft 205 and the disc 206 to rotate. Specifically, in this embodiment, the lower end of the extrusion rod 405 is an I-shaped cylindrical structure. The top surface of the turntable 401 is provided with a rod groove 4011 that slides with the lower end of the extrusion rod 405. The inner wall of the rod groove 4011 is elastically connected to a support plate 4081 via a compression spring 408 on one side of the drive disk 406. The side wall of the support plate 4081 away from the drive disk 406 is in contact with the lower end of the outer wall of the extrusion rod 405. A guide block 407 is fixed on one side of the inner wall of the circular groove 104. The inner wall of the guide block 401 is arc-shaped. The guide block 407 guides the extrusion rod 405 to slide along the rod groove 4011 towards the side closer to the drive disk 406 through the arc surface. A toothed ring 402 is provided on the outer wall of the turntable 401. The toothed ring 402 is meshed with a gear 403. The gear 403 is driven to rotate by a motor 33. The motor 404 is embedded inside the outer shell 100.

[0071] Working principle: Users can put the desiccant after absorbing moisture into the device through the opening of the storage tank 101, and then use the drive mechanism 400 to drive the drying tray 201 to turn the desiccant over and dry it.

[0072] During the process of the motor 404 driving the gear 403, the gear ring 402 meshing with the gear 32 drives the turntable 401 and the rotating shaft 301 coaxially fixedly connected to it to rotate synchronously. If the through port 305 is initially closed, the discharge port 102 is connected to the outside. In this way, the exhaust fan 302 coaxially sleeved on the rotating shaft 301 will draw outside air from the discharge port 102 into the vertical groove 304, and then draw it from the air inlet 308 into the circular cavity 103, and finally blow it out of the device from the air outlet 303. If the through port 305 is initially open, the discharge port 102 is closed. In this way, the air will first enter the receiving trough 101 from the outside and then be drawn into the vertical groove 304 from the through port 305. However, at this time, the silica gel desiccant is in a humid state, and the wind cannot draw it from the through port 305 into the vertical groove 304. Therefore, only the air flows in this process.

[0073] It should be noted that the weight of silica gel desiccant after absorbing moisture can reach 130% to 140% of its original weight in its dry state. With such a large weight difference, it is very convenient for staff to control the wind force and thus control whether the silica gel desiccant is blown. In addition, the through-hole 305 is designed as a slender cylindrical shape, which can make more effective use of wind force and increase the suction force of the through-hole 305 near the storage tank 101 on the silica gel desiccant. This allows for convenient and quick screening of the silica gel desiccant to distinguish whether the silica gel desiccant has been activated.

[0074] As the turntable 401 rotates, the extrusion rod 405 on its top surface also rotates. The initial position of the extrusion rod 405 is at the outermost end of the rod groove 4011, and it does not contact the drive disk 406 during rotation. However, when the extrusion rod 405 rotates to the guide block 407, its outer wall slides along the rod groove 4011 towards the drive disk 406 under the guidance of the arc surface of the inner wall of the guide block 407. Because the size of the guide block 407 is fixed, the contact time between the extrusion rod 405 and the extrusion groove 4061 is also fixed. Thus, after each rotation, the extrusion groove 4061 on the drive disk 406 will have one that corresponds exactly to the direction of the guide block 407. The distance between the long side of the inner wall of the extrusion groove 4061 corresponding to the guide block 407 and the arc surface of the guide block 407 is sufficient for the extrusion rod 405 to pass through, until the extrusion rod 405 contacts the short side of the inner wall of the extrusion groove 4061. When the two parts come into contact, the drive disc 406 will rotate under the push of the extrusion rod 405, thereby driving the connecting shaft 205 and the rest of the structure on it to rotate together. When the position of the extrusion rod 405 passes the guide block 407, the extrusion rod 405 will be pushed back to its original position under the rebound force of the compression spring 408. In this way, the turntable 401 will only drive the drive disc 406 to rotate a fixed angle for each rotation. This will allow the disc 206 and the drive rod 207 on its top surface to rotate intermittently. By extruding the bottom surface of the drying tray 201 by the drive rod 207, the drying tray 201 will be tilted at different angles in the storage slot 101, ensuring that the silica gel desiccant on the drying tray 201 is constantly turned over. This ensures that the silica gel desiccant is exposed to sunlight at different times of the day and also allows the silica gel desiccant to be interchanged, preventing them from piling up and affecting the drying process.

[0075] When the drying tray 201 tilts towards the through opening 305 under the drive of the drive rod 207, the bottom surface of the drying tray 201 will exert a squeezing effect on the top surface of the extrusion plate 3064. Then, the extrusion plate 3064 will drive the first partition 3061 and the second partition 3062 to descend together. Subsequently, the first partition 3061 will open the through opening 305, and the second partition 3062 will close the discharge port 102. The bottom surface of the second partition 3062 is set as a slope structure with the same slope as the bottom surface of the discharge port 102, and its bottom surface is provided with a rubber seal. Therefore, after it descends, it can seal the discharge port 102 to ensure that air does not enter from the discharge port 102. Then, the air generated by the exhaust fan 302 The force will create suction on the side of the through-hole 305 near the storage groove 101, drawing the silica gel desiccant of suitable size and weight into the through-hole 305. The silica gel desiccant drawn into the vertical groove 304 is the activated silica gel desiccant, which will fall on the filter plate 307 and be temporarily blocked on the filter plate 307 by the second partition 3062. When the drying tray 201 is rotated to a position where it is not in contact with the extrusion plate 3064, the multiple support springs 408 will lift the first partition 3061 and the second partition 3062 again, and the through-hole 305 will be closed, while the discharge port 101 will be opened again. The user only needs to place a container at the discharge port 102 to collect the activated silica gel desiccant.

[0076] It is worth mentioning that before the second partition 3062 is completely closed, the gap between its bottom surface and the bottom surface of the outlet 102 still allows for air circulation. Since the opening of the outlet 102 is relatively large, the suction force is relatively dispersed and insufficient to generate suction for the activated silica gel desiccant. Therefore, before the second partition 3062 completely seals the outlet 102, the activated silica gel desiccant in the receiving trough 101 will not be sucked into the vertical groove 304. Furthermore, it can be seen that when the second partition 3062 is slightly raised, the activated silica gel desiccant cannot be sucked into the opening of the through-hole 305 on one side of the receiving trough 101. Additionally, the top surface of the opening of the through-hole 305 on one side of the receiving trough 101 is arc-shaped. The structure itself is designed with a relatively high height on the side near the vertical groove 304, so neither the activated nor the unactivated silica gel desiccant can slide into the vertical groove 304 under the action of gravity. When the drying tray 201 is lifted, a small amount of silica gel desiccant located at the opening end of the through-hole 305 will also be squeezed and guided back into the storage tank 101 along the arc-shaped structure on the top surface of the through-hole 305. Similarly, when the through-hole 305 is completely closed, the air drawn into the device by the exhaust fan 302 will completely enter from the discharge port 102. Such suction is even less sufficient to hold the activated silica gel desiccant. Therefore, after the discharge port 102 is opened, the activated silica gel desiccant can slide out of the device smoothly.

[0077] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
