Description

Technical Field

[0001] The utility model relates to the field of asphalt powder processing, in particular to an asphalt powder mixing device. Background Art

[0002] Asphalt powder refers to a material primarily composed of asphalt, ground into a powder. It is composed primarily of asphaltene, resin, and mineral oil, which give it unique physical and chemical properties, such as viscosity and elasticity. Asphalt powder appears as a black or brownish-black powder with excellent adhesion, enabling it to effectively bond and fix other materials in construction. With the development of the petroleum industry, a growing understanding of oil exploration, drilling, gathering, transportation, and water injection processes has led to a growing role for mud materials in oil exploration and development, and their use is also increasing. Currently, the main anti-collapse agents used in high-temperature, deep-well drilling in the domestic market are sulfonated asphalt powder and asphalt paste. However, sulfonated asphalt powder has drawbacks, including severe foaming in drilling fluids, which impacts drilling operations; low ability to reduce high-temperature, high-pressure fluid loss in mud, resulting in limited wall protection and anti-collapse effectiveness; and insufficient coagulation inhibition and dispersion of drill cuttings. Therefore, there is an urgent need to develop a high-density non-tackifying cationic asphalt powder for drilling fluid that is resistant to high temperatures and suitable for various mud systems. During the processing of this asphalt powder, a mixing device is required to mix asphaltene and resin.

[0003] After searching, the Chinese patent publication number CN220179803U is disclosed, which discloses a rubber powder mixing device for rubber asphalt production. By setting up a mixing mechanism, rubber powder particles are placed in an aggregate box, and the spiral blade can be driven to rotate by the first motor to send the rubber powder particles in the aggregate box to the surface of the bulk material disk. While the second motor drives the stirring rod to rotate, the fifth gear can be driven to rotate through the sixth gear, driving the third rotating shaft to rotate, and then the third gear is driven to rotate through the fourth gear, driving the second rotating shaft to rotate, and then the first gear is driven to rotate by the second gear, so that the first rotating shaft drives the bulk material disk to rotate, and the rubber powder particles are evenly dispersed in the inner cavity of the mixing tank, which facilitates mixing and improves mixing efficiency.

[0004] Since mineral oil or other liquid additives need to be added during the mixing process, the asphalt powder may clump during the mixing process, affecting the uniformity of the mixture. Utility Model Content

After unloading, the baffle is reset under the action of the spring force to seal the feeding port to prevent dust generated during the mixing process from floating out with the feeding funnel 201. When the amount of material to be added is too little to open the baffle, a worker is required to open the baffle. A discharging funnel is welded at the bottom of the mixing drum 2, and a control valve is provided in the discharging funnel.

[0026] A stirring mechanism is provided in the mixing drum 2, and the stirring mechanism includes a first stirring assembly and a second stirring assembly. The first stirring assembly includes a first rotating shaft 301 rotatably connected to the inner top wall of the mixing drum 2, and the outer wall of the first rotating shaft 301 is fixedly connected to a plurality of circumferentially arranged first stirring plates 302. The second stirring assembly includes a second rotating shaft 303 rotatably connected to the inner top wall of the mixing drum 2, and the outer wall of the second rotating shaft 303 is fixedly connected to a plurality of circumferentially arranged second stirring plates 304. The first stirring plates 302 and the second stirring plates 304 are staggered and inclined. The first stirring plates 302 and the second stirring plates 304 are elastic. The top of the first stirring plate 302 and the bottom of the second stirring plate 304 are fixedly connected to a plurality of friction strips 305, and the friction strips 305 increase the rubbing force of the first stirring plates 302 and the second stirring plates 304 on the materials.

[0027] The stirring mechanism also includes a power assembly, which is used to drive the first rotating shaft 301 and the second rotating shaft 303 to rotate in opposite directions. The power assembly includes a mounting bracket 401 bolted to the top of the mixing drum 2. The mounting bracket 401 is L-shaped. A rotating motor 402 is bolted to the mounting bracket 401. The output end of the rotating motor 402 is connected to an auxiliary shaft 403 through a coupling. The bottom end of the auxiliary shaft 403 is rotatably connected to the top of the mixing drum 2. A synchronous belt 404 is connected between the auxiliary shaft 403 and the first rotating shaft 301 through a pulley. The transmission between the auxiliary shaft 403 and the first rotating shaft 301 is achieved through the pulley and the synchronous belt 404. A driving gear 405 is fixedly connected to the auxiliary shaft 403. The top end of the second rotating shaft 303 extends out of the mixing drum 2 and is fixedly connected to a driven gear 406.

The first rotating shaft 301 drives the first stirring plate 302 to rotate. The rotation of the auxiliary shaft 403 will drive the driving gear 405 to rotate. The driving gear 405 engages with the driven gear 406 to drive the driven gear 406 to drive the second rotating shaft 303 to rotate, and the second rotating shaft 303 drives the second stirring plate 304 to rotate. When the first stirring plate 302 on the first rotating shaft 301 overlaps with the second stirring plate 304 on the second rotating shaft 303, the first stirring plate 302 and the second stirring plate 304 move relative to each other, providing a rubbing force for the material mixed in the middle, which facilitates the dispersion of the agglomerated material and ensures the mixing effect.
