[0029] like Figures 1-9 As shown, this utility model discloses a drying device for polycarboxylate superplasticizer, including a support frame 1 and a drying tank 2 mounted on the support frame 1. The drying tank 2 has a drying chamber 7 and a heating chamber 8, which are connected by an air inlet pipe 10. A hot air pipe 9 is provided on the drying tank 2 and is connected to the heating chamber 8. The device also includes a centrifugal atomizer 3, a feeding cylinder 4, a heat recovery assembly 5, and an inner wall cleaning assembly 6. The top of the support frame 1 has a feeding port, and the centrifugal atomizer 3 is located at the feeding port. Inside the drying chamber 7, the bottom of the drying tank 2 is provided with a feeding pipe, the feeding cylinder 4 is provided on the feeding pipe, the support beam is provided on the support 1, the support beam is provided with a support 29, the outer shell 14 is provided on the support 29, the feeding cylinder 4 is provided with a discharge pipe 12, and the inner wall cleaning assembly 6 is provided inside the drying chamber 7; a rotating shaft 22 is provided inside the feeding cylinder 4, a spiral blade 23 is sleeved on the rotating shaft 22, a second motor 24 is provided on the feeding cylinder 4, and one end of the rotating shaft 22 is provided on the output shaft of the second motor 24.
[0030] The heat recovery assembly 5 includes a gas supply pipe 13, a housing 14, and a screw ribbon 15. The housing 14 is sleeved on the feeding cylinder 4. The screw ribbon 15 is located in the cavity formed between the feeding cylinder 4 and the housing 14 and is wound around the feeding cylinder 4. One end of the gas supply pipe 13 is located on the drying tank 2 and communicates with the drying chamber 7. The other end of the gas supply pipe 13 is located on the housing 14. An exhaust pipe 16 is provided on the side of the housing 14 away from the gas supply pipe 13.
[0031] The inner wall cleaning assembly 6 includes a cleaning scraper 17, a toothed ring 18, and a connecting rod 19. The drying tank 2 is provided with a rotating groove 11. The toothed ring 18 is rotatably disposed in the rotating groove 11. The connecting rod 19 is disposed on the toothed ring 18. The cleaning scraper 17 is disposed on the connecting rod 19. The cleaning scraper 17 is used to clean the inner wall of the drying tank 2. The drying tank 2 is provided with a first motor 21. The output shaft of the first motor 21 is provided with a gear 20, which meshes with the toothed ring 18. Two sets of cleaning scrapers 17 are symmetrically arranged.
[0032] The drying tank 2 is equipped with a liquid pump 25, with an inlet pipe 26 at the inlet of the liquid pump 25 and an outlet pipe 27 at the outlet of the liquid pump 25. The other end of the outlet pipe 27 is connected to the inlet of the centrifugal atomizer 3. The drying tank 2 is equipped with a temperature sensor 28, which is used to monitor the temperature inside the drying chamber 7.
[0033] In practical use, hot air is sent into the heating chamber 8 through the hot air pipe 9 and into the drying chamber 7 through the air inlet pipe 10, thereby raising the temperature inside the drying chamber 7. The temperature inside the drying chamber 7 can be monitored by the temperature sensor 28. The polycarboxylate superplasticizer is pumped into the centrifugal atomizer 3 by the liquid pump 25 and sprayed into the drying chamber 7 by the centrifugal atomizer 3. The high-speed centrifugal force rapidly atomizes the liquid into a mist, which allows the polycarboxylate superplasticizer to be dried more quickly, helping to improve drying efficiency and drying effect. The dried solid powder enters the conveying cylinder 4, and the second motor 24 drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the spiral blades 23 to rotate, and the spiral blades 23 convey the powder in the conveying cylinder 4, and finally discharge the powder through the discharge pipe 12. The hot steam generated during the drying process can enter the outer shell 14 through the gas delivery pipe 13, thereby further drying the material in the conveying cylinder 4. This not only improves the drying effect of the material but also reduces energy waste. The spiral ribbon 15 extends the flow path of the hot steam, thereby improving the heat recovery rate. The first motor 21 drives the gear 20 to rotate, which in turn drives the gear ring 18 to rotate. The gear ring 18 drives the cleaning scraper 17 to rotate via the connecting rod 19. When the cleaning scraper 17 rotates, it cleans the inner wall of the drying tank 2, preventing the dried powder from adhering to the inner wall.
[0034] In summary, this solution includes a heat recovery component 5. The hot steam generated during the drying process can enter the outer shell 14 through the gas delivery pipe 13, thereby further drying the material in the material delivery cylinder 4. This not only improves the drying effect of the material but also reduces energy waste. The spiral ribbon 15 can extend the flow path of the hot steam, thereby improving the heat recovery rate. This solution also includes an inner wall cleaning component 6. The first motor 21 can drive the gear ring 18 to rotate, which in turn drives the cleaning scraper 17 to rotate. During the rotation of the cleaning scraper 17, the inner wall of the drying tank 2 can be cleaned to prevent the dried powder from adhering to the inner wall.
