Description

Technical Field

[0001] The utility model relates to the technical field of asphalt processing, in particular to an asphalt heating and mixing device for asphalt paving. Background Art

[0002] At present, most roads are paved with asphalt. Asphalt has a series of properties such as certain viscosity, elasticity, and waterproofness. In the asphalt paving process, asphalt heating and mixing is a key step. In the asphalt paving process, asphalt is heated and mixed with aggregates to form a mixture, which is then spread and compacted on the road surface to eventually form a solid and flat road surface. Asphalt pavement has good durability and traffic carrying capacity, and is widely used in road construction and transportation infrastructure.

[0003] When processing asphalt, heating the mixture is a very important process. At present, the method of heating asphalt is mostly to add the raw materials to the mixing equipment, and stir the raw materials through the stirring components in the mixing equipment to achieve uniform mixing of multiple raw materials.

[0004] Although the above method can mix the raw materials, since the shape of the current stirring equipment is a combination of a cylinder and a cone, the raw materials will fall into the conical bin after entering the cylindrical bin, which causes the stirring component to be unable to stir the raw materials at the bottom position inside, which will affect the stirring and mixing of the raw materials, thereby affecting the processing of the raw materials. Therefore, we propose an asphalt heating mixing device for asphalt paving to solve the above problems. Utility Model Content

[0028] Example

[0029] Reference Figure 1-Figure 6 The utility model provides a technical solution: an asphalt heating and mixing device for asphalt paving, comprising a stirring tank 1 and a mixing mechanism 3, the interior of the stirring tank 1 is fixedly connected to an electric heating plate 2, the mixing mechanism 3 comprises a bottom plate 31, the bottom end of the stirring tank 1 is fixedly connected to a damping rod 311, the telescopic end of the damping rod 311 is fixedly connected to the bottom plate 31, a driving motor 321 is installed on the top of the stirring tank 1, the output end of the driving motor 321 is fixedly connected to a stirring rod 32, an electric telescopic rod 33 is fixedly installed on the top of the stirring tank 1, the telescopic end of the electric telescopic rod 33 is fixedly connected to a top plate 331, and the upper surface of the top plate 331 is fixedly connected to the driving motor 321.

[0030] In a preferred embodiment, the stirring rod 32 passes through the interior of the top plate 331 and is rotatably connected to the interior of the top plate 331. The outer surface of the stirring rod 32 is fixedly connected to the stirring plate 4. In order to facilitate the stirring of the raw materials, the stirring rod 32 passes through the interior of the top plate 331 and is rotated inside the top plate 331, so that the stirring plate 4 can be driven to rotate by the stirring rod 32, thereby stirring the raw materials.

[0031] In a preferred embodiment, the top of the mixing tank 1 is fixedly connected to a feed plate 5, and the upper surface of the feed plate 5 is fixedly connected to a shielding plate 6. Since a top plate 331 is installed on the top of the mixing tank 1, the top plate 331 will shield the top of the mixing tank 1. Therefore, in order to facilitate loading, a feed plate 5 is installed on the top of the mixing tank 1, and two feed plates 5 are provided to add a variety of raw materials into the interior of the mixing tank 1 to facilitate mixing and stirring of the raw materials.

[0032] In a preferred embodiment, the interior of the mixing tank 1 is fixedly connected to the hollow cylinder 7, the upper end of the hollow cylinder 7 is fixedly connected to the inner wall of the mixing tank 1, and the outer surface of the hollow cylinder 7 is fixedly connected to the electric heating plate 2. Heating and mixing the raw materials is a very important step in asphalt processing. Therefore, the present device is provided with a hollow cylinder 7 inside the mixing tank 1, and the outer surface of the hollow cylinder 7 is fixedly installed with the electric heating plate 2. By heating the hollow cylinder 7 with the electric heating plate 2, the raw materials can be heated, thereby ensuring the processing effect of the raw materials.

[0033] At the same time, in order to avoid danger caused by excessive heating temperature, a temperature sensor 8 is fixedly connected to the inner wall of the stirring tank 1, the temperature sensor 8 is electrically connected to the PLC controller 9, the PLC controller 9 is electrically connected to the electric heating plate 2, and the temperature of the outer surface of the hollow cylinder 7 is detected by the temperature sensor 8. If the set temperature is reached, the PLC controller 9 can control the electric heating plate 2 to stop heating, thereby effectively preventing danger.

[0034] After the raw materials are mixed and stirred, they need to be unloaded. The present device is different from the existing one in that the bottom of the mixing tank 1 is flat instead of conical. Therefore, in order to facilitate unloading, a unloading mechanism 11 is installed on the bottom plate 31. The unloading mechanism 11 includes a rotating plate 111, a pushing rod 112 and a limiting frame 113. The upper surface of the bottom plate 31 is rotatably connected to the rotating plate 111, and the bottom of the stirring rod 32 is fixedly connected to the rectangular bar 12. The inside of the rectangular bar 12 is slidably connected to the pushing rod 112. The upper and lower ends of the pushing rod 112 are respectively fixedly connected to the limiting frame 113. The outer surface of the mixing tank 1 is rotatably connected to the limiting frame 113, the internal thread of the limiting frame 113 is connected to the screw 14, and one end of the screw 14 is fixedly connected to the circular plate 10. In actual use, a movable bottom plate 31 is installed at the bottom of the mixing tank 1, and a rotatable rotating plate 111 is installed on the upper surface of the bottom plate 31. The rotating plate 111 is pushed to rotate by the pushing rod 112, so as to drive the rotating plate 111 to rotate, and the raw materials on the upper surface of the bottom plate 31 can be pushed out, which is convenient for unloading the raw materials, saving time and improving the unloading efficiency.

[0035] Specifically, the working process or working principle of an asphalt heating and mixing device for asphalt paving is as follows: when processing asphalt, heating and mixing is a very important process. At present, the method of heating asphalt is mostly to add the raw materials to a mixing device, and stir the raw materials through the stirring component in the mixing device to achieve uniform mixing of multiple raw materials.

[0036] Although the above method can mix the raw materials, since the shape of the current stirring equipment is a combination of a cylindrical and a conical shape, the raw materials will fall into the conical bin after entering the cylindrical bin, which makes it impossible for the stirring component to stir the raw materials at the bottom of the inner part, which will affect the stirring and mixing of the raw materials, thereby affecting the processing of the raw materials. Therefore, the present device is designed to solve this problem, connect an external power supply, and add a variety of raw materials to the interior of the stirring tank 1 through the feed plate 5, and enter the interior of the hollow cylinder 7, and at the same time turn on the electric heating plate 2, and the electric heating plate 2 is used to stir the raw materials. The hollow cylinder 7 is heated, and as the temperature of the hollow cylinder 7 continues to rise, the raw materials inside the hollow cylinder 7 will be heated, and then the driving motor 321 is turned on, and the driving motor 321 drives the stirring rod 32 to rotate, and drives the stirring plate 4 to rotate, so as to stir the raw materials and mix the various raw materials evenly together. In order to facilitate the stirring of the raw materials at the bottom end of the hollow cylinder 7, the pushing rod 112 installed inside the rectangular bar 12 will push the rotating plate 111 to rotate, so as to stir the raw materials at the bottom end of the hollow cylinder 7 and improve the mixing effect.

[0037] In order to avoid danger, the device detects the temperature on the hollow cylinder 7 through the temperature sensor 8. If the temperature on the hollow cylinder 7 reaches the set temperature, the PLC controller 9 can control the electric heating plate 2 to stop heating, thereby avoiding danger.

[0038] After the stirring of the raw materials is completed, the raw materials need to be unloaded, and one end of the limit plate 13 is moved out from the bottom of the bottom plate 31. At this time, the telescopic end of the electric telescopic rod 33 is retracted, and the top plate 331 is driven to move downward, so that the stirring rod 32 can be driven to move downward, and the stirring rod 32 is pushed downward, and then the bottom plate 31 is pushed downward to make the bottom plate 31 detach from the bottom of the mixing tank 1. The bottom plate 31 will move slowly under the action of the damping rod 311. When the bottom plate 31 is detached from the mixing tank 1, the raw materials inside the hollow cylinder 7 will fall directly from the opening position, so the staff can place the receiving bin under the mixing tank 1 to collect the raw materials. At this time, the driving motor 321 is continued to be controlled to rotate, and the driving motor 321 drives the stirring rod 32 to rotate. At the same time, the pushing rod 112 will drive the rotating plate 111 to rotate, so that the rotating plate 111 rotates on the upper surface of the bottom plate 31, thereby pushing the raw materials on the bottom plate 31 to fall and fall into the inside of the receiving bin, so that all the raw materials are collected.

[0039] After the collection of the raw materials is completed, the bottom plate 31 can be restored to its initial state, and the limiting plate 13 can be controlled by the screw rod 14 to press against the bottom plate 31 so that the bottom plate 31 will not fall, thereby meeting the requirements of use.

[0040] It should be noted that the electric heating plate 2, the drive motor 321, the electric telescopic rod 33, the temperature sensor 8 and the PLC controller 9 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
