Description

Technical Field

[0001] The utility model relates to the field of hot air circulation drying devices, and particularly relates to a hot air circulation drying device capable of removing water vapor. Background Technique

[0002] Paper cups are made by vacuum adsorbing and forming wet embryos on special metal molds from pulverized paper pulp, and then the wet embryos are dried by hot air and hot-pressed to obtain formed paper cups. In this production process, a hot air drying device is required. For existing hot air drying devices, in order to avoid wasting heat, hot air is recycled. For example, the Chinese utility model patent with the publication number CN221223154U discloses a hot air circulation drying device. In this utility model, by starting a blower, the hot air blown by a hot air generator is sucked from an air inlet pipe. During the upward movement of the hot air, it passes through medicinal materials, and then through a delivery pipe and finally blows into the interior of the box body through an air outlet pipe. The three air outlet pipes respectively blow hot air onto the medicinal materials on three placement plates, avoiding heat dissipation, recycling hot air, making the hot air blow out evenly, and improving the drying efficiency.

[0003] However, in this utility model, when the hot air rises and comes into contact with the medicinal materials, a large amount of water vapor will be contained in the hot air. When these water vapor are transported by the delivery pipe and the air outlet pipe to the medicinal materials in the box body again, the water vapor in the hot air will flow to the medicinal materials along with the air flow, causing the humidity of the medicinal materials to increase, thereby reducing the drying efficiency of the medicinal materials. Therefore, improvement is needed. Summary of the Utility Model

One end of the air suction pipe 302 is communicated with the drying cylinder 303. The electric heating plate 301 is powered on and heated. Through the heat conduction effect, the workpieces in the drying tray 306 are dried, and the air flow inside the drying box 1 is heated. The hot air flow is extracted by the suction fan 304 and inhaled into the drying cylinder 303. The hot air flow mixed with water vapor passes through the granular desiccant, the ventilation holes of the partition plate 314 and the water-absorbing sponge 315 to remove the water vapor. Then, the hot air flow is discharged into the drying box 1 again through the air inlet pipe 305, so that the heat is conveniently recycled, and the water vapor is removed by the desiccant and the water-absorbing sponge 315, making the drying effect better.

[0023] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the handle rod 310 and the screw rod 313 are respectively fixedly connected to the upper surface and the bottom surface of the cover plate 308. The partition plate 314 is fixedly connected to the screw rod 313. The water-absorbing sponge 315 is fixedly connected to the screw rod 313 and is located below the partition plate 314. The fan blade 317 is fixedly connected to the side surface of the drying tray 306. The hot air circulation assembly 3 further includes a mounting plate 307, a spring 311 and a limiting plate 312.

The handle rod 310 is movably installed on the mounting plate 307. The limiting plate 312 is fixedly connected to the lower end of the handle rod 310. The spring 311 is movably installed on the handle rod 310 and is located between the mounting plate 307 and the limiting plate 312. The hot air circulation assembly 3 further includes a sealing ring 309. The sealing ring 309 is fixedly connected to the cover plate 308 and is movably installed on the drying cylinder 303. The hot air circulation assembly 3 further includes a locking nut 316. The partition plate 314, the water-absorbing sponge 315 and the locking nut 316 are located inside the drying cylinder 303. The locking nut 316 is movably connected to the screw rod 313, and the water-absorbing sponge 315 is located between the partition plate 314 and the locking nut 316. The hot air circulation assembly 3 further includes a support rod 318 and a bearing 319. The support rod 318 is fixedly connected inside the drying box 1, and the support rod 318 is movably installed on the drying tray 306 through the bearing 319. A large number of particle dryers are movably installed on the partition plate 314. There are a large number of gaps between the particles, facilitating the flow of air through. Below the partition plate 314, the water-absorbing sponge 315 is defined by the locking nut 316, and the water-absorbing sponge 315 absorbs the water vapor in the air flow again. When the water-absorbing sponge 315 and the particle desiccant need to be replaced, directly pull the handle rod 310 upward, so that the partition plate 314 and the water-absorbing sponge 315 are removed from the drying cylinder 303. The partition plate 314 will push the particle desiccant out of the drying cylinder 303. After removing the locking nut 316 and replacing the new water-absorbing sponge 315, screw the locking nut 316 back on. After inserting the partition plate 314 into the drying cylinder 303, pour the particle desiccant, so that the desiccant is located above the partition plate 314, thus completing the replacement of the desiccant. After releasing the cover plate 308, the cover plate 308 moves downward under the action of gravity and the spring 311, and the cover plate 308 seals the upper part of the drying cylinder 303 through the sealing ring 309.

[0024] It should be noted that the present utility model is a hot air circulation drying device capable of removing water vapor. An electric heating plate 301 is fixedly connected to the side wall inside the drying box 1. The electric heating plate 301 heats the inside of the drying box 1, causing the temperature of the air flow inside the drying box 1 to rise, drying the workpiece on the drying tray 306. The exhaust fan 304 is started, and air flow is sucked from the upper position of the drying box 1 through the drying cylinder 303 and the suction pipe 302, so that the hot air flow mixed with water vapor in the box enters the drying cylinder 303. A large number of granular desiccants, such as silica gel desiccants, are arranged above the partition plate 314 inside the drying cylinder 303. The shape of the partition plate 314 corresponds to the shape of the drying cylinder 303, and the partition plate 314 slides on the inner wall of the drying cylinder 303. A large number of ventilation holes are arranged on the partition plate 314. A water-absorbing sponge 315 is fixedly connected to the screw 313 at a position below the partition plate 314. With the suction of the exhaust fan 304, the air flow passes through the desiccant, the partition plate 314 and the water-absorbing sponge 315, and is discharged into the drying box 1 again through the air inlet pipe 305. The desiccant and the water-absorbing sponge 315 absorb the water vapor in the hot air. After the hot air flow with the water vapor removed is discharged into the drying box 1 again, the heat is convenient for recycling, and the water vapor contained in the hot air is convenient to remove, making the drying speed faster and the efficiency higher. The air inlet pipe 305 blows the hot air flow against the fan blade 317, causing the drying tray 306 to rotate on the support rod 318 through the bearing 319, so that the workpieces in the drying tray 306 rotate synchronously, and the various sides of the workpieces are constantly switched, fully contacting with the hot air flow, making the drying effect of the workpieces better. Since the desiccant and the water-absorbing sponge 315 will become damp and reduce the dehumidification effect after absorbing a large amount of water vapor, the handle rod 310 is moved upward, causing the cover plate 308 and the limiting plate 312 to move upward synchronously. The limiting plate 312 compresses the spring 311, and the cover plate 308 drives the screw 313 and the partition plate 314 to move upward synchronously. The partition plate 314 pushes the desiccant particles upward and pushes them out of the drying cylinder 303. Then, the partition plate 314 is continuously moved, so that the water-absorbing sponge 315 below the partition plate 314 is moved out of the drying cylinder 303. After the locking nut 316 is removed, the water-absorbing sponge 315 is convenient to replace, so that the desiccant and the water-absorbing sponge 315 are convenient to replace.
