Technical Field

[0001] This utility model relates to the field of concrete mixing technology, specifically to a double-layer centrifugal cement slurry premixing device for improving the uniformity of concrete mixing. Background Technology

[0002] Centrifugal cement slurry premixing equipment is a highly efficient device for preparing cement slurry. It uses centrifugal force to thoroughly mix cement, water, and other additives to form a homogeneous cement slurry. This equipment is widely used in construction, road construction, underground engineering, and other fields, significantly improving the quality of cement slurry and construction efficiency.

[0003] Existing cement slurry premixing equipment uses a mixing tank to hold cement and water, and then an internal mixing rod to agitate them. However, dead zones may exist during the mixing process, resulting in incomplete mixing and localized cement clumping. This affects the smoothness of cement slurry delivery, the uniformity of subsequent molding, and the mixing effect of the concrete, thereby reducing the strength and durability of the structure. Optimization and improvement are necessary. Utility Model Content

[0008] Preferably, a rotating shaft is provided at the middle of the outer side of the mixing cylinder, and the driven wheel is connected to the top of the rotating shaft.

[0009] Preferably, a rotating threaded rod is installed at the top of the feed box, and the pusher plate is connected to the bottom end of the rotating threaded rod.

[0010] Preferably, one end of the feed box is connected to a rotating connecting block, and the extension plate is connected to the inner side of the rotating connecting block.

[0011] Preferably, both sides of the extension plate are connected to elastic connectors, and the inner side of the top of the extension plate is connected to a toggle stop.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1 - Figure 5 As shown, this application provides a double-layer centrifugal cement slurry premixing device for improving the uniformity of concrete mixing, including: a supporting base plate 1, an installation frame 2 is provided at the top center of the supporting base plate 1, and a mixing cylinder 3 is provided on the inner side of the installation frame 2, and a slurry outlet pipe 4 is connected to the bottom end of the mixing cylinder 3. A fixing frame 2 11 is connected to one side of the top of the supporting base plate 1.

[0026] The mixing assembly includes a driven wheel 9, which is located at the top of the mounting frame 2. An inner centrifugal disc 10 is provided on the inner side of the driven wheel 9, and a rotating wheel 7 is provided on the outer side of the driven wheel 9. The mixing assembly is used for the full agitation of the mud.

[0027] Specifically, such as Figure 2 As shown, a fixed frame 5 is installed on the other side of the top of the support base plate 1. A motor 6 is installed on the inner side of the fixed frame 5. A rotating wheel 7 is connected to the top rotating end of the motor 6. The motor 6 controls the rotation of the rotating wheel 7. The rotating wheel 7 meshes with the driven wheel 9. When the driven wheel 9 rotates, it drives the inner mixing drum 3 to perform overall external centrifugal rotation.

[0028] Specifically, such as Figure 3 As shown, a rotating shaft 8 is provided in the middle of the outer side of the mixing cylinder 3. A driven wheel 9 is connected to the top of the rotating shaft 8. The inner ring of the rotating shaft 8 is fixedly connected to the mounting bracket 2. Then, the driven wheel 9 is connected to the top of the outer ring of the rotating shaft 8 to facilitate the rotation of the driven wheel 9.

[0029] The feeding adjustment assembly includes a feeding box 12, which is located at the top of the fixed frame 11. The feeding box 12 has a pusher plate 13 inside and a flow diversion baffle 15 inside. One end of the feeding box 12 has an extension plate 17. The feeding adjustment assembly is used for adjusting the feeding of cement.

[0030] Specifically, such as Figure 4 As shown, a rotating threaded rod 14 is installed at the top of the feed box 12, and a pusher plate 13 is connected to the bottom end of the rotating threaded rod 14. The pusher plate 13 and the rotating threaded rod 14 are threadedly connected, and the pusher plate 13 and the feed box 12 are slidably connected. The pusher plate 13 slides inside the feed box 12 to push the internal material to transfer.

[0031] Specifically, such as Figure 5 As shown, one end of the feed box 12 is connected to a rotating connecting block 16, and the extension plate 17 is connected to the inner side of the rotating connecting block 16. The extension plate 17 and the rotating connecting block 16 are rotatably connected. With the connection of the elastic connecting member 18, the rotation position of the extension plate 17 inside the rotating connecting block 16 can be adjusted.

[0032] Specifically, such as Figure 5 As shown, both sides of the extended material plate 17 are connected to elastic connectors 18, and the inner side of the top of the extended material plate 17 is connected to a toggle bar 19. The extended material plate 17 and the elastic connectors 18 are elastically connected. By toggle the toggle bar 19 to contact the diversion baffle 15, the extended material plate 17 can easily vibrate, allowing the material to be vibrated and transported, which is convenient for dispersion.

[0033] In this embodiment: A driven wheel 9 is provided on the outside of the mixing drum 3 to connect relative centrifugal rotation, and the inner centrifugal disc 10 on the inside can also perform centrifugal rotation at different frequencies to improve the uniformity of mixing. During the cement mixing and feeding process, the material is temporarily stored by the feeding box 12. The cooperation of the pusher plate 13 and the diversion baffle 15 can push the material evenly. Then, the cooperation of the diversion baffle 15 and the extension plate 17 can push the material, so that the extension plate 17 lifts the cement at a certain angle, which facilitates the material to enter the mixing drum 3 for mixing after dispersion.

[0034] Specifically, in the premixing process of concrete slurry, slurry is formed by mixing cement and water according to the specified ratio. Cement is filled into the mixing cylinder 3 through the feed box 12. The pusher plate 13 pushes the cement inward under the action of the rotating threaded rod 14. Then, the diversion baffle 15 disperses the cement evenly and intermittently. The rotation process can also break up the lumps of cement. When the diversion baffle 15 rotates, it will collide with and push the baffle strip 19. Through the rotation connection of the extension plate 17 and the elastic connection of the elastic connector 18, the material on the top of the extension plate 17 can be easily lifted and dispersed, improving the uniformity of mixing. Then, during the mixing process, the inner centrifugal disc 10 rotates centrifugally, and the rotation is adjusted by the meshing rotation of the rotating wheel 7 and the driven wheel 9 on the outside. The inner and outer double-layer centrifugal rotation makes the cement and water form a uniform emulsion mixture and flow out from the slurry outlet pipe 4. The premixed cement slurry is transported to the main mixing equipment to improve the final quality of concrete.
