[0028] The present utility model provides a preparation device 100 for rubber composite modified asphalt.

[0029] As Figures 1-4 shown, in an embodiment of the present utility model, the preparation device 100 for rubber composite modified asphalt includes a mixing cylinder 10, an asphalt cylinder 20, a rubber powder cylinder 30, and a crosslinking agent cylinder 40. The lower ends of the asphalt cylinder 20, the rubber powder cylinder 30, and the crosslinking agent cylinder 40 are respectively provided with a delivery pipe 50, and the delivery pipe 50 is communicated with the mixing cylinder 10. A first baffle 33 is provided on the rubber powder cylinder 30, and a second baffle 43 is provided on the crosslinking agent cylinder 40.

[0030] Among them, the first baffle 33 blocks the falling channel of the rubber powder cylinder 30, and the second baffle 43 blocks the falling channel of the crosslinking agent cylinder 40. Weighing sensors 60 are provided on both the first baffle 33 and the second baffle 43 to weigh the added rubber powder and crosslinking agent. When the first baffle 33 and the second baffle 43 are moved, the raw materials in the rubber powder cylinder 30 and the crosslinking agent cylinder 40 can smoothly slide down into the mixing cylinder 10 and be uniformly mixed with the asphalt.

[0031] In this embodiment, the weighing sensor 60 is a prior art and will not be elaborated here. A receiving plate 61 is provided above the weighing sensor 60. The receiving plate 61 on the first baffle 33 weighs the added rubber powder, and the receiving plate 61 on the second baffle 43 weighs the added crosslinking agent. A micro display screen can be connected to one side of the weighing sensor 60 to display and record the weight of the raw materials on the receiving plate.

[0032] An observation window 11 is provided on the mixing cylinder 10, which is conducive to the staff observing and recording the working conditions inside the mixing cylinder 10. Support frames 13 are provided on both sides of the mixing cylinder 10, and a discharge port 12 is provided at the lower end. The uniformly mixed composite modified asphalt falls from the discharge port 12.

[0033] The selected content of the rubber powder can be 3.0% - 8.0% of the weight of the asphalt, and the content of the cross-linking agent is 2.0% - 6.0% of the weight of the rubber powder. In this way, by separately arranging the rubber powder cylinder 30 and the cross-linking agent cylinder 40, and with the cooperation of the weighing sensor 60, the dosage of each raw material can be very precisely controlled, thereby improving the reaction precision and ensuring the performance of the prepared rubber composite modified asphalt.

[0034] In an embodiment of the present invention, a first notch 31 is formed on the side wall of the rubber powder cylinder 30, a second notch 41 is formed on the side wall of the cross-linking agent cylinder 40, the first baffle 33 can be slidably installed in the first notch 31, and the second baffle 43 can be slidably installed in the second notch 41; a first recess 32 is formed on the inner wall of the rubber powder cylinder 30, the first recess 32 corresponds to the first notch 31, and one end of the first baffle 33 is stuck in the first recess 32; a second recess 42 is formed on the side wall of the cross-linking agent cylinder 40, the second recess 42 corresponds to the second notch 41, and one end of the second baffle 43 is stuck in the second recess 42.

[0035] In this embodiment, a handle 62 is respectively provided on the first baffle 33 and the second baffle 43. Through the handle 62, the first baffle 33 can be pulled out along the first notch 31; the second baffle 43 can be pulled out along the second notch 41, and a limiting platform 63 is provided at the bottom of both the first baffle 33 and the second baffle 43. The limiting platform 63 can prevent the first baffle 33 from completely detaching from the rubber powder cylinder 30; prevent the second baffle 43 from completely detaching from the cross-linking agent cylinder 40. It can be understood that when the first baffle 33 is pulled out, the rubber powder on the receiving plate 61 of the first baffle 33 drops from the rubber powder cylinder 30 into the mixing cylinder 10; when the second baffle 43 is pulled out, the cross-linking agent on the receiving plate 61 of the second baffle 43 drops from the cross-linking agent cylinder 30 into the mixing cylinder 10 and is mixed and stirred with the asphalt, realizing precise control of the raw materials and improving the performance of the rubber composite modified asphalt.

[0036] In an embodiment of the present invention, a stirring roller 71 is arranged inside the mixing cylinder 10, and a driving motor 70 is arranged outside. The driving motor 70 is connected to the stirring roller 71 to drive the stirring roller 71 to rotate. Heating elements 80 are arranged both inside the mixing cylinder 10 and inside the asphalt cylinder 20. The heating elements 80 are used to heat the asphalt; a switching valve 21 is arranged at the lower end of the asphalt cylinder 20. First, the asphalt is heated in the asphalt cylinder 20, and then the switching valve 21 is opened to make the asphalt drop into the mixing cylinder 10.

[0037] In this embodiment, the drive motor 70 is a common servo motor, and the heating element 80 is a heating pipe. Both are prior arts and will not be elaborated here. It can be understood that the heating element 80 in the asphalt cylinder 10 heats the asphalt to a temperature between 110°C and 200°C. The asphalt enters the mixing cylinder 10 from the asphalt cylinder 20. Then, according to the weight of the added asphalt, a corresponding amount of rubber powder is added to the rubber powder cylinder 30, and a corresponding amount of crosslinking agent is added to the crosslinking agent cylinder 40. Then, the first baffle 33 and the second baffle 33 are opened, and the rubber powder and the crosslinking agent enter the mixing cylinder 10. The drive motor 70 is started to drive the stirring roller 71 to fully mix the asphalt, rubber powder and crosslinking agent in the mixing cylinder 10. At the same time, the heating element 80 in the mixing cylinder 10 keeps the asphalt warm continuously, and thus the preparation of the rubber composite modified asphalt is completed.

[0038] Working principle: An appropriate amount of asphalt is loaded into the asphalt cylinder 20. The heating element 80 in the asphalt cylinder 20 heats the asphalt. Then, a corresponding amount of rubber powder is added to the rubber powder cylinder 30, and a corresponding amount of crosslinking agent is added to the crosslinking agent cylinder 40. Then, the first baffle 33 and the second baffle 33 are opened, and the rubber powder and the crosslinking agent enter the mixing cylinder 10. Then, the drive motor 70 is started to drive the stirring roller 71 to fully mix the asphalt, rubber powder and crosslinking agent in the mixing cylinder 10, realizing the precise control of the raw materials, that is, the dosage of the raw materials can be very precisely controlled, thereby improving the reaction precision and ensuring the performance of the prepared rubber composite modified asphalt.
