Technical Field
[0001] The utility model relates to the technical field of mechanical equipment, in particular to a spraying device for changing the acidity of the surface of granite machine-made sand. Background Art
[0002] Asphalt pavement, a seamless, continuous surface, occupies a significant share of modern highway construction due to its sufficient mechanical strength, excellent load bearing capacity, smooth driving, dust-free operation, and low vibration. Commonly used building blocks for asphalt concrete pavements include alkaline limestone and neutral basalt, which are widely used due to their excellent adhesion to asphalt. However, acidic aggregates such as granite and sandstone often lack the required adhesion to asphalt. After pavement construction, water erosion and repeated loading can cause the asphalt to separate from the aggregate, leading to loose particles and the formation of potholes. However, limited natural resources have resulted in a shortage of high-quality aggregates, placing significant pressure on their extraction and supply. Basalt and limestone, ideal coarse aggregates for concrete, are becoming increasingly scarce. Therefore, research on the suitability of weakly alkaline, neutral, and weakly acidic aggregates has become a pressing need in highway construction. Researchers at home and abroad have focused on surface treatment of aggregates to ensure optimal adhesion to asphalt. In order to reduce the acidity of the surface of machine-made sand, this device was invented based on the adhesion between asphalt and aggregate, providing technical support for the subsequent large-scale application of granite aggregate in asphalt pavement projects.

[0026] The stirring assembly includes a stirring shaft 9, a stirring arm 10 and a stirring blade 11. The stirring shaft 9 is vertically installed at the center of the stirring tank 5. The bottom of the stirring shaft 9 is connected to the stirring motor 7 through the mixer belt 8. The top of the stirring shaft 9 passes into the interior of the stirring tank 5. The stirring arm 10 is installed on the side wall of the stirring shaft 9, and the stirring blade 11 is installed on the outer end of the stirring arm 10.
[0027] In the present invention, four stirring arms 10 with different directions are installed on the stirring main shaft 9, and the installation heights of the four stirring arms 10 are different. A stirring blade 11 is installed at the outer end of each stirring arm 10, which can ensure that the stirring component inside the stirring tank 5 can more fully stir the material stored in the stirring tank 5.
[0028] A liquid reservoir 1 filled with limewater is mounted on one side of the mixing tank 5. This reservoir 1 is connected to an air pump 3 via a water pipe 2. The air pump 3 is mounted on a stand 4 and positioned below the mixing tank 5. The air pump 3 is connected to a nozzle 12 mounted inside the mixing tank 5 via the water pipe 2, forming a spraying system.
[0029] In addition, the stirring shaft 9 in this embodiment is a hollow cylindrical structure, and the nozzle 12 is installed on the top of the stirring shaft 9. The water pipe 2 led out from the air pump 3 passes through the inside of the stirring shaft 9 and is connected to the nozzle 12. Through the operation of the air pump 3, the lime water in the liquid storage tank 1 can be sprayed into the stirring tank 5 through the nozzle 12 to adjust the acidity and alkalinity of the material in the stirring tank 5.
[0030] In this embodiment, the installation position of the nozzle 12 is higher than the height of the mixing tank 5, which can further improve the spraying effect of the nozzle 12.
[0031] The stirring tank 5, the stirring main shaft 9, the stirring arm 10 and the stirring blade 11 are all coated with an anti-alkali coating, which can effectively prevent these devices from being corroded by lime water.
[0032] A control panel 6, mounted on a tripod, is mounted at the bottom of the mixing tank 5. This control panel 6 controls the mixing tank 5, air pump 3, and nozzle 12.
