Description

Technical Field

[0001] This utility model relates to the field of coating mixing technology, and in particular to a special pump for waterproof coating mixture. Background Technology

[0002] In the field of building waterproofing engineering, waterproof coatings are increasingly widely used due to their ability to effectively prevent water penetration and protect building structures. With rising demands for waterproofing quality, the precise delivery of waterproof coating mixtures (such as high-viscosity coatings containing particulate components) has become a crucial step. Traditional general-purpose pumps are ill-suited to these characteristics, driving the development of specialized pumps for waterproof coating mixtures to meet the needs of efficient and stable construction, ensuring the quality and efficiency of waterproofing projects.

[0003] In scenarios such as mountain photovoltaic projects and complex building structures, existing pumps are inconvenient to install and fix, lack structural designs that adapt to different terrains and construction layouts; they also generate a lot of noise during transmission and operation, which interferes with the construction environment and makes it difficult to accurately coordinate the construction process, thus reducing construction efficiency.

The inner wall of the limiting ring plate is provided with an annular groove, and a second sealing ring gasket is embedded in the inside of the annular groove. The inner wall of the second sealing ring gasket is in contact with the surface of the rotating rod.

[0008] Preferably, the two conveying gears mesh with each other, and the pinion and the gear mesh with each other.

[0009] Preferably, a drive motor is fixedly connected to the surface of the fixed cover, and the output end of the drive motor is fixedly connected to one end of the rotating column.

[0010] Preferably, the top and bottom of the pump casing and the cover plate are fixedly connected to mounting plates, adjacent mounting plates are in contact with each other, and each mounting plate has three mounting holes on its surface.

[0021] Example 2, as Figure 1-4 As shown, the top and bottom of the pump casing 1, near the center, are fixed and connected to a connecting pipe 2, and one end of the connecting pipe 2 is fixedly connected to a flange 3; the surface of the rotating rod 8, near both ends, is rotatably connected to a limiting ring plate 10 with bearings, and the inner wall of the limiting ring plate 10 is provided with annular grooves 11, and the inside of the annular grooves 11 is embedded with a second sealing ring gasket 12, the inner wall of the second sealing ring gasket 12 is in contact with the surface of the rotating rod 8; the two conveying gears 13 mesh with each other, and the small gear 15 and the large gear 16 mesh with each other; the surface of the fixed cover 14 is fixedly connected to a drive motor 18, and the output end of the drive motor 18 is fixedly connected to one end of the rotating column 17; the top and bottom of the pump casing 1 and the cover plate 7 are fixedly connected to mounting plates 20, adjacent mounting plates 20 are in contact with each other, and the surface of the mounting plates 20 is provided with three mounting holes 21.

A limiting ring plate 10 is rotatably connected to the surface of the rotating rod 8 near both ends via bearings. The inner wall of the limiting ring plate 10 has annular grooves 11, and a second sealing ring gasket 12 is embedded inside each annular groove 11. The inner wall of the second sealing ring gasket 12 is in contact with the surface of the rotating rod 8, effectively sealing both ends of the rotating rod 8. The meshing of two conveying gears 13 enables the conveying... The gear 13 meshes and rotates, and the meshing between the small gear 15 and the large gear 16 enables the large gear 16 to drive the small gear 15 to rotate. The drive motor 18 is fixedly connected to the surface of the fixed cover 14, and the output end of the drive motor 18 is fixedly connected to one end of the rotating column 17, enabling the drive motor 18 to drive the rotating column 17 to rotate.

[0023] Working principle: The drive motor 18 starts, driving the rotating column 17 to rotate. The rotating column 17 drives the large gear 16, which meshes with the small gear 15. The small gear 15 is fixed to one of the rotating rods 8. When the rotating rod 8 rotates, it drives the conveying gear 13 that it meshes with to rotate through the cooperation of the cross hole 19 and the limiting plate 9. The other conveying gear 13 rotates synchronously in the opposite direction due to the meshing action. The two conveying gears 13 mesh and rotate within the pump casing 1, forming a low-pressure zone on the side where the gears are disengaged (suction end). The waterproof coating mixture is drawn into the pump under atmospheric pressure. As the gears rotate, the material is carried to the side where the gears are engaged (discharge end), where the volume decreases and the pressure increases. The mixture is then discharged through the connecting pipe 2. The extrusion pump body achieves stable conveying. The first sealing ring gasket 6 of the fixed ring plate 4 fills the sealing ring groove 5 to prevent leakage between the pump casing 1 and the cover plate 7. The second sealing ring gasket 12 of the limiting ring plate 10 is embedded in the annular groove 11 to seal the rotation gap between the rotating rod 8 and the pump casing 1. The double seal ensures the pump body's sealing performance. The limiting plate 9 is limited in the cross hole 19 to ensure that the rotating rod 8 and the conveying gear 13 rotate synchronously. The limiting ring plate 10 restricts the axial displacement of the rotating rod 8 to ensure the gear meshing accuracy and the pump body's operational stability, adapting to the long-term stable conveying requirements of waterproof coating mixtures.

[0024] The wiring diagram of the drive motor 18 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the drive motor 18 will not be explained in detail.
