Description

Technical Field

[0002] A retanning agent anti-condensation drying device is a specialized piece of equipment used to prevent condensation during the drying process of retanning agents. Through specific structural designs, such as optimized hot air circulation and control of drying temperature and humidity, it avoids moisture condensation during the drying of retanning agents, thus preventing it from affecting product quality. The reason for using a drying device to dry retanning agents is that drying removes excess moisture from the retanning agents, bringing them to the specified moisture content standard. This ensures the chemical stability, storage safety, and performance of the retanning agents when used in leather processing, preventing the retanning agents from deteriorating, clumping, or affecting the accuracy of the tanning process due to excessive moisture.

[0003] However, existing retanning agent drying equipment suffers from insufficient material disturbance during use. This leads to uneven heating of the retanning agent during the drying process, which not only prolongs the drying time and reduces production efficiency, but also causes some retanning agents to deteriorate due to over-drying, or affects the quality of subsequent processing due to insufficient drying, making it difficult to meet the needs of high-quality production.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 As shown, this utility model is a drying device for anti-condensation of retanning agents, including a bottom 1, and further including: a rotating part 2, which is disposed at the top of the bottom 1; and a feeding part 3, which is disposed on the left side of the rotating part 2.

[0020] The rotating part 2 includes a rotating assembly 21, which is mounted on the top of the bottom part 1; and a driving assembly 22, which is mounted on the rotating assembly 21. The rotating assembly 21 includes a support ring assembly 211 fixedly connected to the top of the bottom part 1. A drying tank 212 is rotatably connected to the support ring assembly 211. Several lifting plates 213 are fixedly connected to the inner wall of the drying tank 212. A rotating shaft 214 is rotatably connected to the support ring assembly 211. Two small gears 215 are sleeved on the outer wall of the rotating shaft 214. Two large gears 216 are sleeved on the outer wall of the drying tank 212.

By setting the rotating part 2, during use, the retanning agent requiring drying is placed into the hopper 321 and introduced into the feed pipe 312. Then, the motor 218 is started. The motor 218 drives two small gears 215 and a toothed pulley 315 to rotate synchronously via the rotating shaft 214. When the toothed pulley 315 rotates, it is driven by the toothed belt 316 and the toothed pulley on the rotating rod 313, enabling the rotating rod 313 and the rotating shaft 214 to rotate synchronously. During the rotation of the 13, the auger blades 314 on it can transport the retanning agent in the feed pipe to the drying tank 212.

[0021] The feeding section 3 includes a feeding assembly 31, which is installed on the left side of the drying tank 212; and a circulation assembly 32, which is installed on the feeding assembly 31. The circulation assembly 32 is located on top of the feeding assembly 31. The feeding assembly 31 includes an L-shaped rod 311 fixedly connected to the support ring assembly 211. A feeding pipe 312 is sleeved on the L-shaped rod 311. The right end of the feeding pipe 312 extends into the drying tank 212 and is rotatably connected to the drying tank 212. A rotating rod 313 is rotatably connected to the feeding pipe 312. The left end of the rotating rod 313 extends out of the feeding pipe 312. The outer wall of the rotating rod 313 is fitted with an auger blade 314, which is adapted to the feed pipe 312. A transmission component is provided on the rotating rod 313. The L-shaped rod 311 is located to the left of the support ring assembly 211. The circulation assembly 32 includes a hopper 321 fixedly connected to the outer wall of the feed pipe 312.

A second rotating shaft 325 has a fan blade 326 fitted on its outer wall, and a filter element is installed inside the circulation shroud 322. The hopper 321 is connected to the feed pipe 312. The transmission component includes toothed pulleys 315 fitted on the outer walls of the first rotating shaft 214 and the first rotating rod 313, with toothed belts 316 wound around their outer walls. The toothed pulleys 315 on the outer walls of the first rotating shaft 214 and the first rotating rod 313 have the same external dimensions. The filter element includes two filter screens 327, each installed on the inner wall of the circulation shroud 322. The two filter screens 327 are respectively located on both sides of the circulation shroud 322, and are connected by a feed pipe. Part 3, when the retanning agent is dried in conjunction with hot air in the drying tank, motor 2 324 can also be started. Motor 2 drives fan blade 326 to rotate through shaft 2 325, which generates negative pressure in the circulation hood 322. Under the action of negative pressure, hot air carries the moisture in the drying tank and is discharged through hopper 321 and feed pipe 312. This convection method significantly accelerates the moisture discharge speed, shortens the drying cycle, and improves drying efficiency. At the same time, the hot air in the drying tank is continuously refreshed to ensure that the retanning agent is always in a high-efficiency drying environment, reducing energy consumption, realizing energy-saving production, and meeting the dual requirements of drying efficiency and quality for large-scale industrial production.

[0022] A specific application of this embodiment is as follows: During use, the retanning agent requiring drying is placed in the hopper 321 and fed into the feed pipe 312. Then, the motor 218 is started. The motor 218 drives two small gears 215 and a toothed pulley 315 to rotate synchronously via the rotating shaft 214. When the toothed pulley 315 rotates, it is driven by the toothed belt 316 and the toothed pulley on the rotating rod 313, causing the rotating rod 313 and the rotating shaft 214 to rotate synchronously. During the rotation of the rotating rod 313, the auger blades 314 on it can transport the retanning agent in the feed pipe to the drying tank 212. This design effectively prevents the retanning agent from clogging the feed pipe. After the retanning agent enters the drying tank, dehumidified hot air is introduced into the tank through the hot air pipe 222. At this time, the two large gears 216 on the outer wall of the drying tank mesh with the two small gears 215 on the outer wall of the rotating shaft, driving the drying tank... The internal rotating plates 213 uniformly agitate the retanning agent, preventing uneven heating and promoting the full evaporation of moisture into the hot air. This design improves drying uniformity and prevents the retanning agent from denaturing due to localized overheating, ensuring product quality. When the drying tank is used in conjunction with hot air to dry the retanning agent, motor 324 can be activated. Motor 324 drives the fan blades 326 to rotate via shaft 325, creating negative pressure in the circulation hood 322. Under this negative pressure, the hot air carries the moisture from the drying tank and discharges it through the hopper 321 and feed pipe 312. This convection method significantly accelerates the moisture discharge, shortens the drying cycle, and improves drying efficiency. At the same time, it continuously refreshes the hot air in the drying tank, ensuring that the retanning agent is always in a highly efficient drying environment, reducing energy consumption, achieving energy-saving production, and meeting the dual requirements of drying efficiency and quality for large-scale industrial production.
