[0002] Water-reducing agents are concrete admixtures that reduce the amount of mixing water while maintaining a relatively constant concrete slump. Most of them are anionic surfactants, such as lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. After being added to concrete mixtures, they disperse cement particles, improve workability, reduce unit water consumption, and improve the fluidity of concrete mixtures; or reduce unit cement consumption, thus saving cement. In the preparation of water-reducing agents, the raw materials used in the preparation of water-reducing agents need to be dried.
[0003] A typical drying device consists of a tank and a hot air blower. The hot air blower is located inside the tank. The raw materials to be dried are put into the tank, and the hot air blower is started to dry the raw materials.
[0004] During their research and improvement efforts, the researchers discovered that the location of the raw materials inside the tank was fixed, and the hot air blower only targeted a portion of the raw materials. The portion of the raw materials further away from the hot air blower had a poor drying effect, resulting in lower raw material quality. Utility Model Content
[0005] In order to improve the quality of raw materials, this application provides a drying apparatus for preparing water-reducing agents.

[0038] Reference Figure 2 and Figure 3 A hot air blower 3 is installed on the inner wall of the top of the tank body 1. An air outlet 31 is opened on the air outlet pipe of the hot air blower 3. A rotating pipe 2 passes through the air outlet 31 and a sealing component 4 is provided between the rotating pipe 2 and the air outlet 31. A ventilation hole is opened on the peripheral wall of the section through which the rotating pipe 2 passes through the air outlet 31. Multiple ventilation holes are opened at intervals along the peripheral wall of the rotating pipe 2. A corrugated pipe 32 is connected to the top of the vertical pipe 22. An air outlet end 33 is sleeved on the peripheral wall of the section of the vertical pipe 22 away from the horizontal pipe 21. The air outlet end 33 is connected to the end of the corrugated pipe 32 away from the vertical pipe 22.
[0039] Reference Figure 2 and Figure 4 A baffle 34 is formed at the bottom of the air outlet 33. The surface of the baffle 34 is inclined away from the rotation direction of the air outlet 33. The air outlet 33 is sleeved and slides on the periphery of the vertical pipe 22. A sliding port for connecting the air outlet 33 to the corrugated pipe 32 is opened on the vertical pipe 22. The sliding port is opened along the length of the vertical pipe 22. The air outlet 33 is sleeved and threaded to the lead screw 15. A conductive slip ring 5 for connecting the circuit of the second motor 14 is sleeved on the section of the rotating pipe 2 away from the first motor 13.
[0040] Reference Figure 2 A first stirring plate 231 is welded to the periphery of the crossbar 23. Two first stirring plates 231 are spaced apart along the length of the crossbar 23. A rotating block 233 is welded to the bottom of the crossbar 23. The rotating block 233 is located at the midpoint of the length of the crossbar 23 and is rotatably connected to the inner wall of the bottom of the tank 1.

[0041] Reference Figure 2 The surfaces of the first stirring plate 231 and the second stirring plate 221 are inclined in the direction of rotation of the connected horizontal bar 23 and vertical pipe 22, respectively. When the first stirring plate 231 and the second stirring plate 221 rotate with the horizontal bar 23 and the vertical pipe 22, the inclined surfaces of the first stirring plate 231 and the second stirring plate 221 scoop up the raw materials. The first stirring plate 231 is fixed with a wear-resistant plate 232 by bolts on the side near the bottom of the tank 1. The wear-resistant plate 232 is set along the length of the first stirring plate 231. The side of the wear-resistant plate 232 away from the first stirring plate 231 is attached to the inner wall of the bottom of the tank 1. The side of the second stirring plate 221 near the side wall of the tank 1 is attached to the inner wall of the tank 1.
[0042] When using this drying device, the raw material is fed into the tank 1 through the feed inlet 11. The first motor 13 is started, causing the rotating tube 2 to drive the horizontal tube 21 and the vertical tube 22 to rotate. At the same time, the horizontal rod 23 and the vertical rod 24 rotate with the horizontal tube 21 to agitate the raw material in the tank 1. The horizontal rod 23 and the vertical rod 24 can increase the stability of the vertical tube 22 when agitating the raw material in the tank 1. The rotating block 233 can increase the stability of the drying device when agitating the raw material and extend the service life of the drying device. The hot air blower 3 and the second motor 14 are started. At this time, hot air enters the rotating tube 2 through the ventilation hole of the rotating tube 2, and then flows through the horizontal tube 21 and the corrugated pipe 32 to the air outlet 33. The air outlet 33 moves up and down in the tank 1 along the circumference of the vertical tube 22 with the rotation of the screw 15, so that... Hot air covers the entire tank 1. The baffle 34 of the air outlet 33 can reduce the amount of raw material entering the air outlet 33 when it moves along the vertical pipe 22, ensuring the safety and stability of the air outlet 33 during operation. Together with the first stirring plate 231 and the second stirring plate 221, which are in contact with the inner wall of the tank 1, the raw material in the tank 1 can be stirred and brought into contact with the hot air. The wear-resistant plate 232 can extend the service life of the first stirring plate 231. The inclined plates of the first stirring plate 231 and the second stirring plate 221 can turn the raw material on the side wall and bottom of the tank 1 when the first stirring plate 231 and the second stirring plate 221 rotate inside the tank 1, thereby improving the stirring effect of the drying device on the raw material, improving the drying effect of the raw material, and improving the quality of the raw material.
[0043] Reference Figure 2 and Figure 3 The sealing assembly 4 includes a sealing ring 41 that is snapped into the opening of the air outlet 31. Two sealing rings 41 are provided and are located at the openings at both ends of the air outlet 31. The cross-section of the sealing ring 41 is U-shaped. The inner side of the sealing ring 41 abuts against the peripheral wall of the rotating tube 2, and the outer side of the sealing ring 41 is embedded and snapped into the opening of the air outlet 31. The U-shaped openings of the two sealing rings 41 are opposite each other. A wear-resistant ring 42 is formed on the side of the sealing ring 41 near the rotating tube 2. Two wear-resistant rings 42 are provided and are located at the top and bottom of the side of the sealing ring 41 near the rotating tube 2, respectively. The side of the wear-resistant ring 42 near the rotating tube 2 is in contact with the peripheral wall of the rotating tube 2. Bearings 311 are installed at both ends of the air outlet 31. The inner wall of the bearing 311 is sleeved on the peripheral wall of the rotating tube 2.
[0044] The sealing ring 41 increases the sealing performance at the connection between the air outlet 31 and the rotating pipe 2, reduces the loss of hot air output from the hot air blower 3, improves the drying efficiency of the drying device for raw materials, enhances the drying effect of the raw materials, and improves the quality of the raw materials. The wear-resistant ring 42 can contact the peripheral wall of the rotating pipe 2, reduce the wear of the sealing ring 41, ensure the safety and stability of the sealing ring 41 during operation, and extend the service life of the sealing ring 41. The bearing 311 increases the stability of the rotating pipe 2 during rotation, ensures that the sealing ring 41 can seal the connection between the rotating pipe 2 and the air outlet 31, reduces the wear of the sealing ring 41 caused by the shaking generated during the rotation of the rotating pipe 2, and extends the service life of the sealing ring 41.
[0045] Reference Figure 1 A vibrating ring 6 is welded to the outer wall of the tank body 1, and a vibrating motor 61 is installed on the vibrating ring 6.
