Embodiment 1

[0034] Please refer to figure 1 with image 3 , a modified asphalt mixing and storage mechanism, including a tank body 1, a motor 2, a motor cover plate 3, a double-layer stirring blade 4, a stirring shaft 5, a pumping mechanism 6, a purification box 7, a spiral heating tube 8, a temperature control Mechanism 9, shaker 10; the stirring shaft 5 passes through the outer wall of the tank body 1 and enters the interior of the tank body 1, the double-layer stirring blade 4 is connected to the end of the stirring shaft 5, the spiral heating tube 8 is installed on the curved surface of the tank body, and the spiral heating tube 8 can be used as a heating mechanism to heat the asphalt in the tank. The outermost side of the curved surface of the tank body 1 is covered with an insulating layer. The temperature control mechanism 9 is connected to the spiral heating pipe 8, and the temperature control mechanism 9 is installed inside the tank body; the stirring shaft 5 and The inside of t...

Embodiment 2

[0052] The difference between embodiment 2 and embodiment 1 is that in embodiment 2, the length of the tank body is greater than 7m and less than 12m, and the two motors 2 are respectively fixed at 1 / 4 of the inward direction on both sides of the upper curved surface of the tank body 1;

[0053] Similarly, two double-layer stirring blades 4 and stirring shafts 5 are also provided with two, and the two stirring shafts 5 enter the tank body at 1 / 4 of the inward direction on both sides of the upper curved surface of the tank body 1 respectively. The leaves 4 are respectively connected with two stirring shafts 5 .

[0054] Similarly, in this embodiment, the purification box 7 is installed at 1 / 2 of the length direction of the upper curved surface of the tank body 1 .

Embodiment 3

[0056] Embodiment 3 discloses a modified asphalt agitation storage method, using the modified asphalt agitation storage device as described in embodiment 1 or embodiment 2, comprising the following steps:

[0057] 1) After the hoisting of the mixing tank is completed, open the feed ports 15 on both sides above the modified asphalt mixing storage device, store the asphalt in the storage tank, and observe the amount of asphalt inside the tank in real time through the high-level observation tube 18 , now open the spiral heating tube 8 in the electric control box 14 and the stirring switch of the motor 2, and add the asphalt modifier, then slowly close the feed port 15;

[0058] 2) Turn on the 6 switches of the shaking screen or the pumping mechanism in the electric control box to add the external admixture. Due to the difference in the form and state of the external admixture, the method of adding the external admixture is slightly different in this embodiment, specifically , whe...

Abstract

The invention discloses a modified asphalt stirring and storage device and method, comprising a tank body, a stirring mechanism, a heating mechanism, a temperature control mechanism and a shaking screen, the stirring mechanism passes through the outer wall of the tank body and enters the inside of the tank body, and the inside of the stirring mechanism is set The channel connected with the outside world is used for the transportation of external admixtures; the heating mechanism is installed on the curved surface of the tank, and the outermost side of the curved surface of the tank is covered with an insulation layer, and the temperature control mechanism is connected to the heating mechanism; the shaker is installed inside the tank, and the shaker The outer tank body is provided with an opening for adding the external admixture, and the external admixture entering the tank body through the opening can fall into the shaking sieve. The invention adopts various methods of adding external admixtures, which is more beneficial to the storage of asphalt.

Description

technical field [0001] The invention relates to the field of asphalt storage, in particular to a modified asphalt stirring storage device and method. Background technique [0002] Modified asphalt refers to adding external additives (modifiers) such as rubber, resin, polymer compound, ground rubber powder or other fillers to asphalt, or taking mild oxidation of asphalt to make asphalt or asphalt mixture Asphalt binder made with improved performance. The modified asphalt has reduced temperature sensitivity, increased softening point, and reduced equivalent brittle point, thereby improving the road performance of asphalt and asphalt mixture. At present, modified asphalt has been widely used in high-grade pavements and airport roads. However, due to compatibility problems between base asphalt and modifiers, and segregation problems in factory production and long-term storage and transportation at construction sites, the storage stability of modified asphalt has become an impo...
