[0023] To address the technical problem that existing high-performance grouting materials are prone to introducing lumpy cement during mixing, affecting product quality, this disclosure provides a high-performance grouting material mixing device for offshore wind power, comprising a vessel body 1, a mixing structure 2, and a screening structure 3. The mixing structure 2 is rotatably installed inside the vessel body 1, and the screening structure 3 for removing lumpy cement is fixedly installed above the vessel body 1. A first inlet 11 and a second inlet 12 are provided above the vessel body 1. The screening structure 3 includes a first conveyor belt 31, a second conveyor belt 32, and a vibrating screen 33. The second conveyor belt 32 is fixedly installed below the first conveyor belt 31, and the vibrating screen 33 is fixedly installed below the end of the first conveyor belt 31. The vibrating screen 33 is fixedly installed at the first inlet 11, and the end of the second conveyor belt 32 is located above the second inlet 12.

[0024] It should be noted that the vibrating screen 33 is driven to vibrate by a vibrating motor, which is installed on the side wall perpendicular to the first feed inlet 11 and perpendicular to the first conveyor belt 31. The vibration of the vibrating screen 33 by a vibrating motor is a very mature technology in the prior art, and will not be elaborated on here.

[0025] It should be noted that the first conveyor belt 31 is a filter conveyor belt, and the mesh diameter of the filter conveyor belt surface is larger than the diameter of the cement particles. The second conveyor belt 32 is a conveyor belt other than a filter conveyor belt that has a solid, seamless or mesh structure, such as a common flat conveyor belt. The filter conveyor belt screens out clumps of cement, allowing unclumped cement particles to pass through the first conveyor belt 31 and fall onto the surface of the second conveyor belt 32 for subsequent use.

[0026] It should be noted that the specific structure and principle of the filter conveyor belt, the flat conveyor belt and the vibrating screen 33 are existing technologies. Therefore, the specific internal structure of the filter conveyor belt, the flat conveyor belt and the vibrating screen 33 will not be described in detail here.

[0027] During the mixing process of high-performance grouting material, the workers first pour cement onto the surface of the first conveyor belt 31. The lumpy cement is intercepted and transported by the filter conveyor belt, i.e., the first conveyor belt 31, while the unlumped cement particles pass through the filter conveyor belt, i.e., the first conveyor belt 31, and fall onto the surface of the second conveyor belt 32. Thus, the unlumped cement particles are transported from the second conveyor belt 32 to the second feed inlet 12, and then enter the reactor body 1 from the second feed inlet 12 to be mixed with the additives.

[0028] The lumpy cement is conveyed by the first conveyor belt 31 to the vibrating screen 33 and falls onto the surface of the vibrating screen 33. The lumpy cement particles are vibrated on the surface of the vibrating screen 33, which causes the slightly lumpy cement particles to disperse and be screened into the second feed port 12, and then enter the interior of the reactor body 1 through the second feed port 12 to mix with the additives.

[0029] The vibrating screen 33 is arranged at an angle. The angled arrangement of the vibrating screen 33 allows slightly agglomerated cement particles to be dispersed by vibration, which increases the filtration efficiency and makes it less prone to clogging, thus facilitating the dispersion of slightly agglomerated cement for screening.

[0030] A recycling bin 34 is fixedly installed at the lower horizontal end of the vibrating screen 33. In conjunction with the inclined arrangement of the vibrating screen 33, the filtration efficiency is improved and clogging is reduced. At the same time, it also facilitates the sliding of heavily clumped cement particles into the recycling bin 34 at the lower horizontal end, so that the heavily clumped cement can enter the recycling bin 34 for recycling and subsequent processing.

[0031] It should be noted that, in order to facilitate cement entering the recycling bin 34, a bin opening 341 is provided between the recycling bin 34 and the first feed inlet. The bottom of the bin opening 341 is inclined to facilitate cement entering the recycling bin 34.

[0032] A discharge port 13 is provided at the bottom of the vessel body 1, and a screw conveyor 14 is fixedly installed at the discharge port 13. After the high-performance grout is mixed, it enters the screw conveyor 14 through the discharge port 13 at the bottom of the vessel body 1, and is discharged by the screw conveyor 14.

[0033] It should be noted that a solenoid valve is fixedly installed in the discharge port 13, thereby controlling the discharge status through the solenoid valve.

[0034] The stirring and mixing structure 2 includes a planetary gear set. The planetary gear set is installed at the axial end of the vessel body 1. A central shaft 21 and an eccentric shaft 22 are fixedly installed on the planetary gear set.

[0035] The planetary gear set includes a gear ring 23, a central gear 24, and an eccentric gear 25. The gear ring 23 is rotatably mounted on the inner wall of the end of the vessel body 1. The central gear 24 is rotatably mounted on the inner wall of the end of the vessel body 1 at the axis of the gear ring 23. A drive motor 26 is fixedly mounted on the outside of the end of the vessel body 1 and is coaxially connected to the central gear 24. An eccentric gear 25 is meshed between the central gear 24 and the gear ring 23. A central shaft 21 is fixedly mounted at the axis of the central gear 24. An eccentric shaft 22 is fixedly mounted at the eccentric position of the eccentric gear.

[0036] After cement particles enter the reactor body 1, the drive motor 26 is activated, causing the central gear 24 and central shaft 21 to rotate. The rotation of the central gear 24 drives the eccentric gear 25 to rotate around it, which in turn drives the eccentric shaft 22 to rotate around the central shaft 21. During this rotation, the eccentric shaft 22 also rotates around the axis of the eccentric gear 25, further increasing the complexity of the mixing process and thus improving the mixing effect. The increased complexity of the mixing process, achieved by the rotation of the central shaft 21 and the simultaneous revolution of the eccentric shaft 22 around the central shaft 21 and rotation around the axis of the eccentric gear 25, enhances the mixing effect of the high-performance grouting material and ultimately improves product performance.

[0037] It should be noted that stirring blades for stirring are fixedly mounted on the surfaces of the central shaft 21 and the eccentric shaft 22. Furthermore, the length of the stirring blades fixedly mounted on the eccentric shaft 22 can be adjusted according to the actual application dimensions, thereby ensuring that the stirring blades do not contact the central shaft 21 during the axial rotation of the eccentric shaft 22 around the eccentric gear 25. It should also be noted that the stirring blades on the surfaces of the central shaft 21 and the eccentric shaft 22 are staggered.

[0038] It should be noted that the toothed ring 23, the central gear 34 and the eccentric gear 35 are detachably sealed to the inside of the vessel body 1 by an end cover plate 4, thereby protecting the toothed ring 23, the central gear 34 and the eccentric gear 35.

[0039] The first inlet 11 and the second inlet 12 are arranged adjacent to each other, with the second inlet 12 in contact with the bottom of the first conveyor belt 31. Unagglomerated cement particles screened by the first conveyor belt 31 above the second inlet 12 can fall directly into the second inlet 12 for feeding, while unagglomerated cement particles screened by the first conveyor belt 31 outside the second inlet 12 fall into the second conveyor belt 32 and are fed along the second conveyor belt 32 toward the second inlet 12.

[0040] When mixing high-performance grout, the workers first pour cement onto the surface of the first conveyor belt 31. The lumpy cement is intercepted and transported by the filter conveyor belt, i.e., the first conveyor belt 31, while the unlumped cement particles pass through the filter conveyor belt, i.e., the first conveyor belt 31, and fall onto the surface of the second conveyor belt 32. This allows the unlumped cement particles to be transported from the second conveyor belt 32 to the second feed inlet 12, and then enter the reactor body 1 through the second feed inlet 12 to be stirred and mixed with the additives. This process allows for the screening of cement particles, preventing cement particles with impaired performance from affecting the performance of the high-performance grout. It also helps to ensure the stability of the reaction during the mixing process of the high-performance grout and the construction quality.

[0041] The clumped cement continues to be conveyed by the first conveyor belt 31 towards the vibrating screen 33 and falls onto the surface of the vibrating screen 33. The clumped cement particles are vibrated on the surface of the vibrating screen 33, causing the slightly clumped cement particles to disperse and be screened into the second feed inlet 12, thus entering the reactor body 1 to mix with additives. The heavily clumped cement particles slide into the recovery bin 34 at the lower horizontal end, allowing the heavily clumped cement to enter the recovery bin 34 for subsequent recycling and processing. This process enables the slightly clumped cement particles to disperse and screen out cement particles with stable particle size, while the heavily clumped cement particles with impaired performance are directionally conveyed for recycling.

[0042] After cement particles enter the reactor body 1, the drive motor 26 is activated, causing the central gear 24 and central shaft 21 to rotate. The rotation of the central gear 24 drives the eccentric gear 25 to rotate around it, which in turn drives the eccentric shaft 22 to rotate around the central shaft 21. During this rotation, the eccentric shaft 22 also rotates around the axis of the eccentric gear 25, further increasing the complexity of the mixing process and thus improving the mixing effect. The increased complexity of the mixing process, combined with the rotation of the central shaft 21 and the simultaneous revolution of the eccentric shaft 22 around the central shaft 21 and rotation around the axis of the eccentric gear 25, enhances the mixing effect of the high-performance grout and ultimately improves product performance.

[0043] After the high-performance grout is mixed, it is discharged from the outlet 13 below the reactor body 1 and conveyed by the screw conveyor 14.

[0044] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
