[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1 to 9As shown, a high-efficiency drying device for cement grinding aid includes a drying mechanism 1 and a filtering mechanism 2. The drying mechanism 1 includes a horizontally placed outer barrel 101. A feed inlet 103 and an exhaust pipe 102 are fixedly connected to the top of the outer barrel 101. A filtering device 107 is fixedly connected to the connection between the exhaust pipe 102 and the outer barrel 101. The advantage of the filtering device is that it prevents the cement grinding aid from flowing out of the exhaust pipe 102 during machine operation, allowing only water vapor to flow out. From the outside to the inside, the outer barrel 101 is sequentially connected to an annular heating device 4, a roller 5, and a stirring mechanism 6. The annular heating device 4 is fixedly connected to the outer barrel 101 and is used to heat and evaporate the moisture from the cement grinding aid. The annular heating device 4 has an opening communicating with the exhaust pipe 102 and the feed inlet 103, facilitating feeding through the feed inlet 103 and exhausting through the exhaust pipe 102. A bracket 104 is fixedly connected to the opening at one end of the outer barrel 101, and a baffle is fixed to the other end. One end of the stirring mechanism 6 is rotatably connected to the opening on the bracket 104, and the other end is rotatably connected to the baffle. This provides support for the stirring mechanism 6 and prevents it from shaking during operation. The drum 5 includes a bottom 501, and five scraper plates 505 are fixedly connected to one side of the bottom 501. The outer side of the scraper plates 505 is rotatably connected to the annular heating device 4. During operation, the scraper plates 505 scrape the inside of the annular heating device 4 to prevent adhesion from forming on the inner wall of the annular heating device 4. A scraper block 506 is fixedly connected inside the scraper plate 505. The scraper block 506 cooperates with the impact block 605, which can strike the scraper block to shake off the cement grinding aid on the scraper plate. A gear ring 502 is fixedly connected to the other side of the barrel wall of the barrel bottom 501. Three limiters are fixed on the side of the barrel bottom 501 with the gear ring 502. Planetary gears 503 are rotatably connected to the limiters. The planetary gears 503 are rotatably connected to the gear ring 502.

[0029] like Figure 6 As shown, the scraper 505 is curved, thinner at both sides and thicker in the middle. The thinner parts facilitate scraping the annular heating device 4, while the thicker parts provide support. The scraper block 506 inside the scraper 505 is also curved. This has the advantage that when rotated clockwise, the cement grinding aid rotates inward, and when rotated counterclockwise, the cement grinding aid rotates outward. It is not necessary to lift one end of the device to move the cement grinding aid out; it can be achieved simply by rotating the drive device 2 3 in both directions.

[0030] like Figure 7As shown, the stirring mechanism 6 includes a shaft 601 rotatably connected to the drum 5. One end of the shaft 601 is fixedly connected to a sun gear 504, which is rotatably connected to a planetary gear 503. A drive device 2 3 is fixedly connected to the outer drum body 101 near the sun gear 504. The extended end of the drive device 2 3 is fixedly connected to the shaft 601. When the drive device 2 3 rotates the shaft 601, the sun gear 504, which is fixedly connected to the shaft 601, drives the planetary gear 503. When the gear ring 502 rotates, the shaft 601 and the drum 5 rotate in opposite directions. Multiple sets of fixing blocks 602 are fixedly connected to the shaft 601 inside the outer drum body 101. A rod 603 is rotatably connected to the fixing block 602. One end of the rod 603 is rotatably connected to a chain 604, and one end of the chain 604 is rotatably connected to an impact block 605. The advantage of this design is that the rods 603 can prevent adjacent sets of rods 603 from getting tangled and knotted, while the chain 604 ensures the flexibility of the connection between the end and the impact block 605. Two bases 105 are fixedly connected to the bottom of the outer barrel 101, and two telescopic devices 106 are fixedly connected to the bases near the support 104.

[0031] like Figures 8 to 9 As shown, the filter mechanism 2 includes a second bracket 202, with four casters 205 fixedly connected to the bottom for easy movement. A bucket support 208 is fixedly connected to the upper part of the second bracket 202, surrounding the internal filter bucket 206. This design prevents dust from scattering when the dry cement grinding aid is sieved. The filter bucket 206 is rotatably connected inside the bucket support 208. The filter bucket 206 has a semi-enclosed design, with a mounting post 2061 fixedly connected to one side. The mounting post 2061 passes through the bucket support 208 and is fixedly connected to a driven gear 204. A drive device 201 is fixedly connected to the second bracket 202 on one side of the bucket support 208. A drive gear 203 is fixedly connected to the extended end of the drive device 201, and the drive gear 203 is rotatably connected to the driven gear 204. A limit switch 207 is fixedly connected to one side of the second bracket 202.

[0032] The limiting device 207 is fixedly connected to the extended end of the telescopic device 106. An opening on one side of the filter barrel 206 is rotatably connected to the outer barrel body 101. A ramp on one side of the barrel support 208 facilitates material discharge; after sieving, the cement grinding aid slides down the ramp for easy collection by workers. The filter barrel 206 includes a barrel body 2062, with multiple sets of 180° filter holes 2063 on the barrel wall. The size of the filter holes 2063 can be designed according to specific requirements. A waste outlet 2064 is provided on the opposite side of the barrel wall of the multiple sets of filter holes 2063, allowing the discharge of waste material remaining after sieving. During drying operations, one side of the inside of the filter barrel 206 abuts against the outer barrel body 101 to prevent leakage of the cement grinding aid.

[0033] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0034] Working process: First, the telescopic device 106 is in the retracted state, ensuring that the filter mechanism 2 and the drying mechanism 1 are in a sealed state, and the annular heating device 4 is started. The upper cover of the feed inlet 103 is opened, cement grinding aid is added inside, and the upper cover is closed after filling is completed.

[0035] The second step is to start the drive device 2 3. The drive device 2 3 drives the drum 5 and the stirring mechanism 6 to rotate, which accelerates the drying of the cement grinding aid. During the operation, water vapor will be discharged through the exhaust pipe 102. The exhaust pipe 102 is equipped with a filter device 107 to prevent the cement grinding aid from being discharged. When the cement grinding aid is drying quickly, it is easy to clump together. The scraper 505 on the drum 5 can scrape the cement grinding aid on the inner wall of the annular heating device 4. The impact block 605 on the stirring mechanism 6 generates vibration by striking the scraper block 506, which can vibrate down the cement grinding aid remaining on the scraper 505. The impact block 605 can also break up large pieces of cement grinding aid during the stirring process.

[0036] After the cement grinding aid is completely dried in the third step, the telescopic device 106 is activated. The telescopic device 106 pushes the filter mechanism 2 to move outward. After the movement is completed, the drive device 2 3 reverses, and the scraper 505 reverses, moving the dried cement grinding aid inside into the filter barrel 206 of the filter mechanism 2. The impact block continues to strike the scraper 506, moving a small amount of cement grinding aid stuck on the scraper 505 into the filter barrel. The drive device 1 201 is activated, and the filter barrel 206 is rotated through gear meshing, causing the filter barrel 206 to swing back and forth 30°. The powdered cement grinding aid falls through the filter hole 2063 onto the barrel support 208 and is transported to the outside. The large pieces of cement grinding aid produced after filtration can be retracted by the telescopic device 106 and returned to the drying mechanism 1 for secondary crushing. If other impurities are filtered out, the filter barrel 206 can be rotated 180° by the drive device 1 201, and the other impurities can be discharged through the waste outlet 2064.

[0037] In the fourth step, the telescopic device 106 retracts, causing the filter mechanism to move towards the drying mechanism 1 to await the second drying.

[0038] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
