TECHNICAL FIELD

[0001] The utility model relates to bitumen processing equipment technical field, concretely relates to a modified bitumen cooling container. BACKGROUND

[0002] In the field of modern road construction and maintenance, modified bitumen is widely used due to its excellent performance. In the production process of modified bitumen, the temperature of finished modified bitumen is usually maintained at about 180 degrees. This high temperature state is crucial to ensure the quality of modified bitumen, because appropriate temperature helps the uniform dispersion and fusion of the modifier in the bitumen, ensuring that its performance indicators achieve the expected effect. In order to reduce the temperature of modified bitumen under the premise of ensuring its quality.

[0003] The common practice at present is to first manufacture a high-concentration mother liquor. The specific operation process is as follows: first, a mother liquor containing a high-concentration modifier is prepared, and then base bitumen with a temperature of 110 to 120 degrees is poured into the mother liquor. In this way, the temperature of the overall mixture is adjusted using the relatively low temperature of the base bitumen, in an attempt to achieve the purpose of cooling. However, this cooling method has obvious limitations. After a large number of tests, it is found that the temperature of modified bitumen can only be reduced by about 5 degrees using this method. Such slow cooling speed far fails to meet the demand for rapid cooling of modified bitumen in actual production, and it is difficult to effectively curb the aging process of bitumen at high temperature. Therefore, we propose a modified bitumen cooling container to solve the above problems. SUMMARY

[0030] Working process description:

[0031] (I) Preparation work

[0032] According to the production requirement, a proper amount of modified asphalt mother liquor and base asphalt are prepared (the temperature of the modified asphalt mother liquor is relatively high, close to 180 degrees, and the temperature of the base asphalt is 110-120 degrees), and the two kinds of asphalt are added to the inside of the feeding bin 3 through the feeding pipes 4 in a certain proportion, and the feeding amount and feeding speed of the two kinds of asphalt are controlled during the feeding process (the existing technology has a device for controlling the feeding rate, which is not the problem to be solved by the application, and therefore will not be described here), so that the two kinds of asphalt can be mixed in a proper proportion.

[0033] (II) Cooling process

[0034] When the mixed asphalt falls from the collecting tank 1, the fan 6 is operated to generate airflow, the airflow is used to accelerate the heat dissipation of the surface of the asphalt in a convection manner, at the same time, the water inlet and the water outlet of the cooling pipe 7 are opened, so that the cooling water flows in the cooling pipe 7, and the cooling water flowing through the cooling pipe 7 can absorb the heat transferred from the asphalt in the collecting tank 1, thereby further reducing the temperature of the asphalt.

[0035] The modified asphalt cooling container accelerates the dissipation of heat on the surface of the asphalt by using air convection through the cooperation of the air hood 5 and the fan 6, and realizes double cooling of the asphalt (one side is cooled by air convection, and the other side is cooled by cooling water conduction) by combining the circulation of cooling water in the cooling pipe 7, which greatly improves the cooling speed. Compared with the traditional method of adjusting the temperature of base asphalt, the device can quickly reduce the temperature of the modified asphalt to the appropriate range, effectively solving the problem of slow cooling speed in the prior art.

[0036] As shown in Figure 1 In some embodiments, the discharge chute 201 is arc-shaped, and the lower side thereof is connected to the top of the cooling pipe 7. More specifically, since the discharge chute 201 is arc-shaped, this shape conforms to the characteristics of the flow of asphalt liquid, can reduce the flow resistance, and enables the asphalt to flow more smoothly from the aggregate tank 1 to the top of the cooling pipe 7, just like water flowing in a curved river. The arc-shaped discharge chute 201 provides a natural “channel” for the asphalt, avoiding the occurrence of dead angles or stagnation of the asphalt during the flow process, and ensuring the continuity of the entire cooling process.

[0037] As shown in Figure 2 In some embodiments, the air hood 5 is inclined upward. More specifically, during the cooling process of the modified asphalt, the asphalt is in a liquid state and has a certain flowability. The air hood 5 is inclined upward, and the direction of the air flow generated by the fan 6 is consistent with the inclination direction of the air hood 5. The asphalt droplets will flow downward along the inner wall of the air hood 5 under the action of gravity, rather than entering the fan 6 against the direction of the air flow. This is like placing an inclined baffle in a water flow. The water flow (air flow) will flow along the direction of the baffle, and the heavier objects (asphalt droplets) will deposit under the action of gravity.

[0038] As shown in Figure 1 In some embodiments, the edge of the aggregate tank 1 gradually decreases in height from the side close to the mounting block 2 to the other side. More specifically, when the edge of the aggregate tank 1 gradually decreases in height, a natural “slope” structure is formed inside the aggregate tank 1. Under the action of gravity, hot air has a tendency to rise, and cooler air will sink. This height difference creates favorable conditions for natural convection of air. Air convection circulation can continuously transfer heat from the surface of the asphalt to the surrounding air. With the rising of hot air and the replenishment of cold air, heat can be dissipated more quickly from the surface of the asphalt to the outside.

[0039] As shown in Figure 4As shown in the drawings, in some embodiments, a stirring piece 8 is further included, which is arranged on the inner bottom side of the feeding bin 3, and is used to mix the asphalt mother liquor with the base asphalt, the stirring piece 8 comprises a driving motor 801 installed on the back of the feeding bin 3, and an output shaft of the driving motor 801 is connected with a rotating table 802 penetrating through the outer wall of the feeding bin 3, and a plurality of stirring plates 803 are fixedly arranged on the edge side of the rotating table 802 in an annular array, and the bottom of the feeding bin 3 is circular, and the end of the stirring plate 803 away from the rotating table 802 is slidably connected with the inner wall of the feeding bin 3, and more specifically, when the motor output shaft rotates, the rotating table 802 is driven to rotate, so that the stirring plate 803 installed on the rotating table 802 can also perform circumferential motion, and this motion conversion mechanism ensures that the stirring plate 803 can effectively stir and mix the asphalt inside the feeding bin 3, and mix the asphalt mother liquor and the base asphalt together.

[0040] As Figure 4 shown in the drawings, in some embodiments, the stirring plate 803 is arc-shaped, and more specifically, compared with the design of right angle or sharp edge, the arc shape has no obvious dead angle, and the asphalt is easy to accumulate at the right angle or sharp angle, because the flow of the asphalt is not smooth at these places, and the transition of the arc shape enables the asphalt to continuously flow and not suddenly accumulate at a certain point, and is not easy to stick, and in the production process, the asphalt is not likely to form a thick adherent layer on the stirring plate 803, which greatly reduces the frequency and difficulty of cleaning.

[0041] The above description of disclosed embodiments enables those skilled in the art to carry out or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
