Description

Technical Field

[0001] This utility model relates to the field of building coating mixing technology, and in particular to a mixing device for building wall coatings. Background Technology

[0002] In the construction industry, the mixing quality of building coatings directly affects the coating performance and construction effect. Currently, building coatings (such as latex paint, waterproof coatings, and thick-film putty) are mostly composed of multiphase components such as pigments, fillers, emulsions, and additives. The different components have large differences in density and particle size, and are prone to stratification and sedimentation after standing (such as heavy pigments sinking and emulsion phases floating). Therefore, uniform mixing is required before construction or during production.

[0003] Existing mixing technologies mainly rely on paddle or turbine mixing devices: paddle mixing propels materials through the circular motion of blades, but its radial disturbance is strong while its axial circulation is insufficient, which easily leads to uneven mixing of materials between upper and lower layers. Especially for high-viscosity coatings, dead zones are easily formed between the edge of the paddle and the container wall, causing pigment agglomeration or insufficient dispersion of additives. Turbine mixing forms strong vortices through high-speed rotation. Although it has high mixing efficiency, it will entrain a large amount of air, leaving residual air bubbles in the coating. After application, defects such as pinholes and bulges are likely to occur. Moreover, the strong shear force generated by high speed can significantly damage sensitive additives (such as defoamers and film-forming aids). Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a building wall coating mixing device that effectively solves the problems of insufficient mixing and residual air bubbles that cause pinholes during construction.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows:

[0006] A wall coating mixing device for building construction includes a mixing box. A first rotating column is rotatably arranged inside the mixing box. A second rotating column rotating in the opposite direction is rotatably installed inside the first rotating column. A first rotating plate is installed at both ends of the first rotating column. A second rotating plate corresponding to the first rotating plate is installed at both ends of the second rotating column. A plurality of through holes are opened on both the first rotating plate and the second rotating plate. A scraper that is slidably connected to the inner wall of the mixing box is provided at one end of both the first rotating plate and the second rotating plate.

[0007] Preferably, a motor is installed at the upper end of the mixing box, and a drive bevel gear is fixedly connected to the output end of the motor. A first auxiliary bevel gear and a second auxiliary bevel gear are respectively meshed at both ends of the drive bevel gear. The first auxiliary bevel gear is fixedly installed on the upper end of the first rotating column, and the second auxiliary bevel gear is fixedly installed on the upper end of the second rotating column.

[0008] Preferably, mounting brackets are provided at both ends of the second rotating column, and the second rotating plate is fixedly connected to the mounting brackets.

[0009] Preferably, the mixing box is provided with a feeding port at the upper end.

[0010] Preferably, the lower end of the mixing box is provided with a discharge pipe, and a valve is provided on the discharge pipe.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] By using a first and second rotating plate with through holes, and rotating in opposite directions, the coating is cut through the through holes and formed into multiple fluid streams as the two porous rotating plates rotate circumferentially. The uniform distribution of the through holes ensures that the material is subjected to equal disturbance at different radial positions, avoiding insufficient mixing in certain areas. In addition, the first and second rotating plates can form opposite fluid movements, causing the coating to generate vortices in both the axial and radial directions, breaking the tendency of layering and ensuring that pigments, additives and other components are fully mixed.

Detailed Implementation

[0018] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1-4As shown, a building wall coating mixing device includes a mixing box 1. A first rotating column 9 is rotatably arranged inside the mixing box 1. A second rotating column 13 rotating in the opposite direction is rotatably installed inside the first rotating column 9. A first rotating plate 10 is installed at both ends of the first rotating column 9. A second rotating plate 12 corresponding to the first rotating plate 10 is installed at both ends of the second rotating column 13. A plurality of through holes 14 are opened on the first rotating plate 10 and the second rotating plate 12. A scraper 11 that is slidably connected to the inner wall of the mixing box 1 is provided at one end of the first rotating plate 10 and the second rotating plate 12.

[0020] In use, pigments, fillers, emulsions, and other coating raw materials are added to the mixing tank 1. The first rotating column 9 is controlled to rotate, which drives the first rotating plate 10 to rotate. At the same time, the second rotating column 13 drives the second rotating plate 12 to rotate in the opposite direction to the first rotating plate 10. During the rotation of the first rotating plate 10 and the second rotating plate 12, due to the setting of the through holes 14, when the two porous rotating plates rotate circumferentially, the coating is cut through the through holes 14 on the plates and forms multiple fluid streams. The uniform distribution of the through holes 14 can ensure that the material is subjected to equal disturbance at different radial positions, avoiding insufficient local mixing. In addition, the first rotating plate 10 and the second rotating plate 12 can form opposite fluid movements, causing the coating to generate complex vortices in both the axial and radial directions, breaking the stratification trend and ensuring that the pigments, additives, and other components are fully mixed.

[0021] A motor 3 is installed at the upper end of the mixing box 1. The output end of the motor 3 is fixedly connected to a drive bevel gear 4. The two ends of the drive bevel gear 4 are respectively meshed with a first auxiliary bevel gear 6 and a second auxiliary bevel gear 5. The first auxiliary bevel gear 6 is fixedly installed on the upper end of the first rotating column 9, and the second auxiliary bevel gear 5 is fixedly installed on the upper end of the second rotating column 13.

[0022] like Figure 1 and 2 As shown, when motor 3 is working, the output end of motor 3 drives the active bevel gear 4 to rotate. The active bevel gear 4 drives the first auxiliary bevel gear 6 and the second auxiliary bevel gear 5 to rotate in opposite directions. The first auxiliary bevel gear 6 drives the first rotating column 9 to rotate, and the second auxiliary bevel gear 5 drives the second rotating column 13 to rotate.

[0023] The second rotating column 13 has mounting brackets 15 at both ends, and the second rotating plate 12 is fixedly connected to the mounting brackets 15.

[0024] like Figure 3 As shown, the mounting bracket 15 serves to fix and support the second rotating plate 12, ensuring that the second rotating plate 12 can rotate with the second rotating column 13.

[0025] The mixing box 1 is provided with a feeding port 2 at its upper end.

[0026] like Figure 1 As shown, the raw materials are added into the mixing box 1 through the feeding port 2.

[0027] The lower end of the mixing box 1 is provided with a discharge pipe 7, and a valve 8 is provided on the discharge pipe 7.

[0028] like Figure 1 As shown, the uniformly stirred coating can be discharged through the discharge pipe 7, and the valve 8 can control the opening and closing of the discharge pipe 7.

[0029] The working process of this utility model is as follows: When in use, pigments, fillers, emulsions, and other coating raw materials are added to the mixing box 1 through the feeding port 2. The motor 3 is controlled to work, and the output end of the motor 3 drives the active bevel gear 4 to rotate. The active bevel gear 4 drives the first set of bevel gears 6 and the second set of bevel gears 5 to rotate in opposite directions. The first set of bevel gears 6 drives the first rotating column 9 to rotate, and the second set of bevel gears 5 drives the second rotating column 13 to rotate. The first rotating column 9 drives the first rotating plate 10 to rotate. At the same time, the second rotating column 13 drives the second rotating plate 12 to rotate in the corresponding direction. The rotating plates 10 rotate in opposite directions. During the rotation of the first rotating plate 10 and the second rotating plate 12, due to the setting of the through holes 14, the coating is cut through the through holes 14 on the plates and forms multiple fluid streams when the two porous rotating plates rotate in a circle. The uniform distribution of the through holes 14 can make the material be disturbed equally at different radial positions, avoiding insufficient local mixing. In addition, the first rotating plate 10 and the second rotating plate 12 can form opposite fluid movements, so that the coating generates complex vortices in both the axial and radial directions, breaking the tendency of layering and ensuring that pigments, additives and other components are fully mixed.

[0030] Open valve 8 to discharge the well-stirred paint through discharge pipe 7.
