Description

Technical Field

[0001] This utility model relates to the field of asphalt mixture preparation technology, and in particular to a composite modified asphalt mixture preparation device. Background Technology

[0002] Asphalt is a complex, dark brown mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. In the asphalt production process, mixing is usually achieved by using a mixer. To improve the quality of the mixed asphalt, a heater is usually installed on the outside of the drum to heat the drum body, thereby heating the asphalt inside the drum. However, this heating method can only heat the outer part of the asphalt. Even with a mixing paddle, some of the asphalt in the inner circle still cannot be fully mixed and heated with the drum body, resulting in unsatisfactory quality of the asphalt after remixing.

[0003] To address the aforementioned issues, existing patent (CN221982161U) discloses a composite modified asphalt mixture preparation device. After the asphalt to be mixed is poured into the tank, it disperses into the main mixing tank and multiple auxiliary mixing tanks according to its own fluidity. Then, the heater is activated to heat the tank, raising its internal temperature. When the asphalt in the main and auxiliary mixing tanks is stirred, the heating surface is located inside the asphalt pile, ensuring that the portion inside the asphalt is also fully heated.

[0004] However, in the aforementioned prior art, the existing devices cannot stir the asphalt that has settled to the bottom, resulting in poor stirring effect. Utility Model Content

[0005] The purpose of this invention is to provide a composite modified asphalt mixture preparation device, which aims to solve the technical problem that existing devices in the prior art cannot stir the asphalt that has settled to the bottom, resulting in poor stirring effect.

[0006] To achieve the above objectives, this utility model employs a composite modified asphalt mixture preparation device, comprising a base plate and a fixed frame mixing assembly, wherein the base plate is fixedly connected to the fixed frame and is located below the fixed frame;

[0007] The stirring assembly includes a stirring tank, a fixed ring, a rotating rod, a rotating component, and a stirring component. The rotating rod is rotatably connected to the fixed frame and passes through the fixed frame. The fixed ring is fixedly connected to the rotating rod and is located at one end of the rotating rod. The stirring tank is detachably connected to the fixed ring and is located inside the fixed ring. The rotating component is located on one side of the fixed frame, and the stirring component is located inside the stirring tank.

[0008] The rotating component includes a mounting plate, a placement plate, a worm gear, a worm, and a stabilizing unit. The mounting plate is fixedly connected to the fixed frame and located on one side of the fixed frame. The placement plate is fixedly connected to the fixed frame and located on one side of the fixed frame. The worm gear is detachably connected to the rotating rod and located at the end of the rotating rod away from the fixed ring. The worm is rotatably connected to the mounting plate and located inside the mounting plate, and the worm gear meshes with the worm. The stabilizing unit is located on the side of the fixed frame near the mixing tank.

[0009] The stabilizing unit includes a stabilizing rod, the surface of the fixing frame has a stabilizing groove, the stabilizing rod is fixedly connected to the fixing ring and located on the side of the fixing ring close to the fixing frame, and the stabilizing rod is slidably connected to the stabilizing groove.

[0010] The stirring component includes a top cover, a fixing tube, a heating tube, a first gear, and a stirring unit. The top cover is detachably connected to the stirring tank and is located above the stirring tank. The fixing tube is detachably connected to the stirring tank and is located inside the stirring tank. The heating tube is detachably connected to the stirring tank and is located inside the fixing tube. The first gear is detachably connected to the fixing tube and is located above the fixing tube. The stirring unit is disposed inside the stirring tank.

[0011] The stirring unit includes a connecting rod, a second gear, and a stirring rod. The second gear meshes with the first gear and is located on one side of the first gear. The connecting rod is detachably connected to the second gear and is located above the second gear. The stirring rod is detachably connected to the second gear and is located below the second gear.

[0012] This invention relates to a composite modified asphalt mixture preparation device. Asphalt is poured into a mixing drum. Starting the mixing motor drives the connecting rod to rotate, which in turn drives the second gear to rotate around the first gear. This causes the mixing rod to rotate simultaneously around the heating tube, thereby mixing the asphalt inside the mixing drum. Starting the rotating motor fixed above the placement plate drives the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the rotating rod to rotate. The rotation of the rotating rod causes the fixing ring and the mixing drum to flip. After the mixing drum flips, the asphalt at the bottom is stirred, thus increasing the mixing efficiency and improving the mixing effect. Attached Figure Description

[0022] This utility model provides a composite modified asphalt mixture preparation device, including a base plate 101, a fixing frame 102 and a mixing assembly. The base plate 101 is fixedly connected to the fixing frame 102 and is located below the fixing frame 102.

[0023] The stirring assembly includes a stirring tank 103, a fixing ring 104, a rotating rod 105, a rotating component, and a stirring component. The rotating rod 105 is rotatably connected to the fixing frame 102 and passes through the fixing frame 102. The fixing ring 104 is fixedly connected to the rotating rod 105 and is located at one end of the rotating rod 105. The stirring tank 103 is detachably connected to the fixing ring 104 and is located inside the fixing ring 104. The rotating component is disposed on one side of the fixing frame 102, and the stirring component is disposed inside the stirring tank 103.

[0024] In this embodiment, asphalt is poured into the mixing tank 103. Starting the mixing motor 120 drives the connecting rod 116 to rotate, which in turn drives the second gear 117 to rotate around the first gear 115. This causes the mixing rod 118 to rotate on its own axis while simultaneously rotating around the heating tube 114, thereby achieving the purpose of mixing the asphalt inside the mixing tank 103. Starting the rotating motor 119 fixed above the placement plate 107 drives the worm gear 109 to rotate. The rotation of the worm gear 109 drives the worm wheel 108 to rotate, which in turn drives the rotating rod 105 to rotate. The rotation of the rotating rod 105 causes the fixing ring 104 and the mixing tank 103 to flip. After the mixing tank 103 is flipped, the asphalt at the bottom can be mixed, thereby increasing the mixing efficiency and improving the mixing effect.

[0025] Further, the rotating component includes a mounting plate 106, a placement plate 107, a worm gear 108, a worm 109, and a stabilizing unit. The mounting plate 106 is fixedly connected to the fixed frame 102 and is located on one side of the fixed frame 102. The placement plate 107 is fixedly connected to the fixed frame 102 and is located on one side of the fixed frame 102. The worm gear 108 is detachably connected to the rotating rod 105 and is located at the end of the rotating rod 105 away from the fixed ring 104. The worm 109 is rotatably connected to the mounting plate 106 and is located inside the mounting plate 106, and the worm gear 108 meshes with the worm 109. The stabilizing unit is disposed on the side of the fixed frame 102 near the mixing tank 103.

[0026] In this embodiment, the mounting plate 106 fixes the position of the worm gear 109. Activating the rotating motor 119 fixed above the placement plate 107 drives the worm gear 109 to rotate. The rotation of the worm gear 109 drives the worm wheel 108 to rotate, which in turn drives the rotating rod 105 to rotate. The rotation of the rotating rod 105 causes the fixing ring 104 and the mixing tank 103 to flip. After the mixing tank 103 is flipped, the asphalt at its bottom can be stirred, thereby increasing the stirring efficiency and improving the stirring effect.

[0027] Furthermore, the stabilizing unit includes a stabilizing rod 110, the surface of the fixing frame 102 has a stabilizing groove 111, the stabilizing rod 110 is fixedly connected to the fixing ring 104 and is located on the side of the fixing ring 104 close to the fixing frame 102, and the stabilizing rod 110 is slidably connected to the stabilizing groove 111.

[0028] In this embodiment, when the fixed ring 104 flips, the stabilizing rod 110 will slide in the stabilizing groove 111, thereby sharing part of the load borne by the rotating rod 105, thus increasing the stability of the mixing tank 103 when it flips.

[0029] Furthermore, the stirring component includes a top cover 112, a fixing tube 113, a heating tube 114, a first gear 115, and a stirring unit. The top cover 112 is detachably connected to the stirring tank 103 and is located above the stirring tank 103. The fixing tube 113 is detachably connected to the stirring tank 103 and is located inside the stirring tank 103. The heating tube 114 is detachably connected to the stirring tank 103 and is located inside the fixing tube 113. The first gear 115 is detachably connected to the fixing tube 113 and is located above the fixing tube 113. The stirring unit is disposed inside the stirring tank 103.

[0030] In this embodiment, the fixing tube 113 fixes the position of the first gear 115, and the heating tube 114 can heat the asphalt in the mixing tank 103.

[0031] Furthermore, the stirring unit includes a connecting rod 116, a second gear 117, and a stirring rod 118. The second gear 117 meshes with the first gear 115 and is located on one side of the first gear 115. The connecting rod 116 is detachably connected to the second gear 117 and is located above the second gear 117. The stirring rod 118 is detachably connected to the second gear 117 and is located below the second gear 117.

[0032] In this embodiment, starting the stirring motor 120 can drive the connecting rod 116 to rotate, thereby driving the second gear 117 to rotate around the first gear 115, so that the stirring rod 118 rotates on its own axis while rotating around the heating tube 114, thereby achieving the purpose of stirring the asphalt inside the mixing tank 103.
