Example 2

[0027] This embodiment discloses a putty powder with good defoaming effect, which comprises the following components in parts by weight: 600 parts of double fly ash powder, 300 parts of hydrated lime powder, 3 parts of graphene oxide fiber, 2 parts of chitosan fiber, 5 parts of vitrified microspheres, 0.3 part of hydroxyethyl cellulose, 5 parts of lignin, and 0.5 part of amylase. Example 3

[0028] This embodiment discloses a putty powder with good defoaming effect, which comprises the following components in parts by weight: 650 parts of double fly ash powder, 200 parts of hydrated lime powder, 2 parts of graphene oxide fiber, 1 part of chitosan fiber, 1 part of vitrified microspheres, 0.1 part of hydroxyethyl cellulose, 3 parts of lignin, and 0.3 part of amylase. Example 4

[0029] This embodiment discloses a putty powder with good defoaming effect, which comprises the following components in parts by weight: 700 parts of double fly ash powder, 400 parts of hydrated lime powder, 4 parts of graphene oxide fiber, 3 parts of chitosan fiber, 10 parts of vitrified microspheres, 0.5 part of hydroxyethyl cellulose, 10 parts of lignin, and 1.0 part of amylase. Example 5

[0030] This embodiment discloses a preparation method of a putty powder with good defoaming effect. The method comprises the following steps: S1. Weigh double fly ash powder, hydrated lime powder, and hydroxyethyl cellulose according to the parts by weight, put them into a stirring device, and at the same time add distilled water, and stir to obtain a paste-like mixture; S2. Add graphene oxide fiber, chitosan fiber, vitrified microspheres, hydroxyethyl cellulose, lignin, and amylase to the paste-like mixture and stir evenly; S3. Take out the mixture stirred evenly in S2 and let it stand for drying; S4. Crush the dried material to 60μm - 80μm, and pack it.

[0031] Among them, the stirring speed in S1 is 500 - 650r / min, and the stirring time is 2 - 3 hours.

[0032] Specifically, the stirring speed in S3 is 800 - 900r / min, and the stirring time is 30 - 40 minutes. Example 6

[0033] This embodiment discloses a stirring device applied to Example 5. Specifically, the stirring device comprises a stirring tank 5, a lifting component, and a stirring component. The lifting component is installed on the outer circumferential surface of the stirring tank 5, and one end of the stirring component is connected to the lifting component, and the other end extends into the stirring tank 5 to stir the material.

[0034] The lifting assembly includes a lifting base 1 and a lifting frame 2, and the lifting frame 2 is installed on the upper end of the lifting base 1. Specifically, the lifting base 1 is a hydraulic cylinder, and the hydraulic cylinder can be controlled by a controller to drive the lifting frame 2 to move up and down. The lifting assembly drives the stirring assembly to move up and down, so that the stirring assembly moves up and down during the stirring process, so that the stirring assembly can stir more evenly.

[0035] Among them, in order to further improve the stirring effect, a number of collision blocks 8 are arranged on the inner wall of the stirring tank 5. When the material is stirred by the stirring component, the material near the wall of the stirring tank 5 collides with the collision blocks 8, thereby forming a turbulent flow, which can improve the stirring effect on the one hand, and prevent the material from adhering to the wall of the stirring tank 5 on the other hand.

[0036] In this embodiment, the stirring assembly includes a motor 3, a transmission shaft 4, a mounting shaft 10 and a plurality of stirring paddles 9. The motor 3 is mounted on the upper end of the stirring tank 5. The transmission shaft 4 is transmission-connected to the output end of the motor 3. One end of the transmission shaft 4 extends into the stirring tank 5. A connecting shaft 21 is provided at the lower end of the transmission shaft 4. The mounting shaft 10 is detachably mounted on the connecting shaft 21. A plurality of stirring paddles 9 are evenly distributed on the mounting shaft 10. Further, a plurality of axial guide limiting edges 20 are provided on the outer surface of the connecting shaft 21. An axial mounting hole 17 cooperating with the connecting shaft 21 is provided on the mounting shaft 10. A guide groove 18 cooperating with the guide limiting edge 20 is provided on the hole wall of the mounting hole 17. A magnet 16 engaging with the connecting shaft 21 is provided at the bottom of the mounting hole 17.

[0037] In this embodiment, the stirring assembly further includes a locking assembly, which locks the installation shaft 10 when the connecting shaft 21 rotates, and releases the locking of the installation shaft 10 when the connecting shaft 21 stops rotating. Specifically, the locking assembly includes a connector 6, a spring 13, and a plurality of stirring paddles 7. The connector 6 is rotatably mounted on the upper end of the installation shaft 10. The connector 6 is provided with an axial mounting hole 15 that matches the connecting shaft 21. The hole wall of the mounting hole 15 is provided with a guide groove 14 that matches the guide limiting rib 20. The groove wall of the guide groove 14 is provided with a convex rib 12 and a spring 13. The guide limiting rib 20 is provided with a slot 19 that matches the convex rib 12. One end of the spring 13 away from the groove wall of the guide groove 14 abuts against the guide limiting rib 20. The plurality of stirring paddles 7 are radially mounted on the connector 6.

[0038] It should be noted that, in order to ensure that the connector 6 can rotate, the width of the second guide groove 14 must be greater than the width of the guide limiting edge 20 .

[0039] As is known to those skilled in the art, since the surface of the stirring shaft is constantly in contact with the object being stirred during operation, the surface is prone to rust and wear. Therefore, the stirring shaft needs to be replaced frequently. However, the existing stirring shafts are usually connected to the motor 3 by bolts, which is inconvenient to disassemble, and the entire stirring shaft needs to be replaced during replacement.

[0040] In the above technical solution, the mounting shaft 10 is detachably connected to the connecting shaft 21 by a magnet 16. During disassembly, only need to pull the mounting shaft 10 downward forcefully so that the magnet 16 in the first mounting hole 17 of the mounting shaft 10 is separated from the connecting shaft 21, then the mounting shaft 10 can be removed. During installation, only need to align the first mounting hole 17 on the mounting shaft 10 with the connecting shaft 21 and put the mounting shaft 10 on until the magnet 16 is attracted to the connecting shaft 21, the mounting and dismounting of the mounting shaft 10 is convenient; moreover, when the transmission shaft 4 rotates, the connecting head 6 rotates accordingly. During the rotation of the connecting head 6, the connecting head 6 is compressed by the reaction force of the material to be stirred against the spring 13, causing the connecting head 6 to rotate relative to the connecting shaft 21. The convex ribs 12 on the connecting head 6 are caught in the card slots 19 on the guiding and limiting ribs 20, forming an axial limit for the mounting shaft 10, improving the connection stability of the mounting shaft 10 during operation. And the stirring paddle two 7 in the locking assembly can improve the overall stirring effect of the device; in this technical solution, when the transmission shaft 4 rotates, the convex ribs 12 on the connecting head 6 are caught in the card slots 19 on the guiding and limiting ribs 20, forming an axial limit for the mounting shaft 10. When the transmission shaft 4 does not rotate, the connecting head 6 resets under the action of the spring 13, and the convex ribs 12 are separated from the card slots 19, then the mounting shaft 10 can be removed, and it is not necessary to replace the entire stirring shaft.

[0041] The above is only an illustration of the best embodiments of the present invention, but it should not be construed as a limitation of the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to vary. All changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
