Description

Technical Field

[0001] The present application relates to the technical field of modified asphalt, and in particular to an anti-segregation storage tank for modified asphalt. Background Art

[0002] Modified asphalt is an asphalt binder made by adding external additives (modifiers) such as rubber, resin, high molecular polymer, ground rubber powder or other fillers, or taking measures such as mild oxidation of asphalt to improve the performance of asphalt or asphalt mixture. There are two mechanisms for modifying asphalt: one is to change the chemical composition of asphalt, and the other is to make the modifier evenly distributed in the asphalt to form a certain spatial network structure.

[0003] For example, Chinese patent CN211077131U discloses an anti-segregation storage tank for modified asphalt, which mainly solves the problem of interference caused by the heating mechanism and the stirring and spraying mechanism being located inside and outside the storage tank respectively, and the heating mechanism heats the modified asphalt evenly, which can effectively prevent the modified asphalt from segregating.

[0004] The length of the stirring blades in the storage tank does not extend directly to the bottom of the inner wall of the tank body, and the stirring blade cover is directly fixed at the upper middle end of the tank body for rotation and stirring. This will cause the asphalt at the edge and the bottom of the tank body to not be fully stirred, thereby greatly reducing the heating efficiency, thereby reducing the effect of preventing asphalt segregation.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] like Figure 1-5 As shown, the utility model provides a technical solution: an anti-segregation storage tank for modified asphalt, comprising a storage tank 1 and a fixed plate 2 fixedly connected to the top of the storage tank 1, a stirring mechanism 31 is arranged inside the storage tank 1, a heating temperature control mechanism 32 is arranged above the stirring mechanism 31, the stirring mechanism 31 comprises a motor 311 fixedly connected to the bottom end of the fixed plate 2, a telescopic rod 312 is fixedly connected to the output end of the motor 311, a limiting groove 313 is provided on the inner wall of the extended end of the telescopic rod 312, a limiting block 314 is slidably connected to the inner wall of the limiting groove 313, a rotating rod 315 is fixedly connected to the outer wall of the limiting block 314, the outer wall of the rotating rod 315 is slidably connected to the inner wall of the extended end of the telescopic rod 312, a stirring blade 316 is fixedly connected to the outer wall of the rotating rod 315, the number of the stirring blades 316 is four, the number of the connected stirring blades 317 is two, the length of the stirring blades 316 and the connected stirring blades 317 is the same as that of the rotating rod 315 The outer wall is equal to the length of the inner wall of the storage tank 1, so that the asphalt can be stirred and flowed, and the asphalt can be fully heated. At the same time, the longer stirring blade 316 can stir the asphalt at the edge of the tank body. The outer wall of the bottom end of the rotating rod 315 is fixedly connected to a connecting stirring blade 317, and the bottom end of the connecting stirring blade 317 is fixedly connected to a second stirring blade 318. The number of the second stirring blades 318 is four, and the second stirring blades 318 are a group of two and are distributed at the bottom of the connecting stirring blade 317 in a left-right symmetrical structure. In this way, the asphalt at the bottom of the storage tank 1 can be stirred by the second stirring blade 318 to prevent the asphalt at the bottom from not being fully stirred, thereby reducing the anti-segregation effect. A threaded groove 319 is provided at one end of the rotating rod 315 away from the telescopic rod 312, and a threaded sleeve 3110 is fixedly connected to the bottom end of the inner wall of the storage tank 1, and the inner wall of the threaded groove 319 is threadedly connected to the inner wall of the threaded sleeve 3110.

[0035] Furthermore, there are two limit grooves 313 and two limit blocks 314, which are distributed on the inner wall of the telescopic rod 312 and the outer wall of the rotating rod 315 in a left-right symmetrical structure. In this way, the left and right ends of the rotating rod 315 are limited, which can make it more stable after limitation.

[0036] Furthermore, the inner wall of the limiting groove 313 fits in with the outer wall of the limiting block 314 , so that the limiting block 314 can be fitted and limited, thereby preventing the rotating rod 315 from being limited during the rotation process.

[0037] The heating and temperature control mechanism 32 includes an air suction pump 321 connected to the top of the storage tank 1, an air outlet pipe 322 is connected to the top of the air suction pump 321, a thermometer 323 is connected to the top of the storage tank 1, a connecting rod 324 is fixedly connected to the outer wall of the telescopic rod 312, and a heating plate 325 is fixedly connected to the bottom end of the connecting rod 324.

[0038] Furthermore, there are two heating plates 325, which are distributed at the bottom end of the connecting rod 324 in a bilaterally symmetrical structure, so as to heat the asphalt, prevent the asphalt from cooling and solidifying, and prevent segregation after cooling.

[0039] Furthermore, the length of the heating plate 325 is equal to the distance between the bottom end of the connecting rod 324 and the bottom end of the inner wall of the storage tank 1, so that the heating plate 325 can fully heat the asphalt from top to bottom, thereby improving the anti-segregation effect.

[0040] The implementation principle of the present application is as follows: first, asphalt is put into the storage tank 1 through the feeding tank at the top thereof. During the long-term placement process, in order to prevent the asphalt from being segregated, the motor 311 can be started to rotate forward and reversely, and its output end drives the telescopic rod 312 to rotate. The rotation of the telescopic rod 312 can drive the rotating rod 315 to rotate, thereby driving the threaded groove 319 at the bottom to rotate, and then the rotating rod 315 can be threadedly rotated with the threaded sleeve 3110. At this time, the rotating rod 315 can be limited by the limiting groove 313 and the limiting block 314, and move upward or downward. In this way, it can also move up and down during the rotation process, thereby driving the stirring blade 316, the connecting stirring blade 317 and the second stirring blade 318 to rotate and move up and down, so that the asphalt inside the storage tank 1 can be fully stirred to prevent the segregation phenomenon when it is left standing;

[0041] When the telescopic rod 312 is rotating, it will also drive the connecting rod 324 to rotate. When the connecting rod 324 rotates, it can drive the heating plate 325 to rotate, and the heating plate 325 is started synchronously to heat the asphalt while the heating plate 325 rotates to prevent the asphalt from solidifying and causing segregation after standing. The temperature inside the storage tank 1 can be observed through the thermometer 323. When the temperature is too high, the suction pump 321 can be started to suck out the hot air and then discharge it through the outlet pipe 322, thereby reducing the temperature inside the storage tank 1 and maintaining a relatively stable temperature.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
