Description

Technical Field

[0001] This utility model relates to the field of asphalt processing technology, and in particular to a special asphalt mixing machine. Background Technology

[0002] Asphalt is a dark brown, complex mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form, with a black surface. It is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementitious material. Specialty asphalt, on the other hand, is a high-grade asphalt material. It is made by adding modifiers (such as rubber, resin, and high-molecular polymers) to asphalt or through mild oxidation processing. Its composition is more complex, and it possesses unique properties and applications.

[0003] In the production and mixing process of specialty asphalt, modifiers need to be added. Modifiers come in various states, including fixed powder, liquid, and latex. Currently, the traditional method is to directly pour the modifier into the mixing tank. This easily leads to uneven mixing of the modifier and asphalt, requiring a long time and thorough mixing, which is time-consuming and energy-intensive. There is an urgent need for a device that can evenly sprinkle different types of modifiers into the mixing tank. To this end, we have designed a specialty asphalt mixing machine. Utility Model Content

[0004] The purpose of this invention is to provide a special asphalt mixing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A special asphalt mixing machine includes a mixing tank and a storage tank. The bottom of the mixing tank is provided with multiple support legs, and a feed inlet is provided on one side of the mixing tank. A circular plate that rotatably mates with the mixing tank is provided on the top of the mixing tank. A toothed ring is fixedly provided on the top of the circular plate. An annular bottom plate is fixedly fitted on the upper part of the outer surface of the mixing tank. A U-shaped frame is provided on the top of the annular bottom plate. A storage tank is provided on the top of the U-shaped frame. A material hopper with a downward-sloping opening is provided at the bottom of the storage tank. A discharge pipe is provided at the bottom of the material hopper. An upper connecting pipe is rotatably fitted on the outer side of the discharge pipe. The top end of the upper connecting pipe is rotatably connected to the inner top wall of the U-shaped frame. The bottom end of the upper connecting pipe is connected to a conveying inclined pipe through a connecting bend A. The other end of the conveying inclined pipe is connected to a lower connecting pipe through a connecting bend B. The lower connecting pipe passes through the circular plate and communicates with the interior of the mixing tank. The lower connecting pipe is fixedly connected to the circular plate.

[0007] As a preferred embodiment of this utility model: a support rod is fixedly provided in the upper connecting pipe along the horizontal direction, and a feeding auger is rotatably provided at the top center of the support rod. The feeding auger passes through the discharge pipe and extends into the interior of the material hopper.

[0008] As a further preferred embodiment of this utility model: the top of the annular base plate is provided with a fixed seat, the top of the fixed seat is provided with a drive motor, the output shaft of the drive motor is connected to a drive gear, and the drive gear is meshed with the gear ring.

[0009] As a further preferred embodiment of this utility model: a rotating shaft is provided at the bottom center of the circular plate, and multiple stirring rods are provided on the outer side of the rotating shaft.

[0010] As a further preferred embodiment of this utility model: a support column is provided at the top center of the circular plate, and the top end of the support column is fixedly connected to the outer surface of the conveying inclined pipe.

[0011] As a further preferred embodiment of this utility model: the top of the storage hopper is provided with a top cover via a hinge, and the top of the top cover is provided with a handle.

[0012] As a further preferred embodiment of this utility model: an installation opening is provided at the top center of the U-shaped frame, and the storage bucket is fixedly embedded in the installation opening.

[0013] The beneficial effects of this utility model are as follows: In this device, the storage tank is used to hold the modifier. Specifically, during use, the drive motor can drive the drive gear to rotate. Through meshing, the gear ring and the circular plate rotate together, which in turn drives the lower connecting pipe, the conveying inclined pipe, and the upper connecting pipe to rotate. That is, the feeding auger in the upper connecting pipe also rotates. With the setting of the material hopper at the bottom of the storage tank, the modifier can be evenly conveyed downwards. The modifier is conveyed to the lower connecting pipe through the upper connecting pipe and the conveying inclined pipe. The lower connecting pipe is embedded in the circular plate and moves in a circular motion with the circular plate, thereby conveying the modifier through the lower connecting pipe. The additive discharged from the pipe can be evenly dispersed from the top of the mixing tank, ensuring rapid, thorough, and uniform mixing with the asphalt and improving work efficiency. It is worth mentioning that the feeding auger is mainly used to transport fixed powdered and latex-like additives, while liquid additives can flow downwards through the gap between the auger blades and the inner wall of the discharge pipe. The feeding auger also plays a certain buffering role for the liquid. Similarly, the liquid additives can also be evenly dispersed into the mixing tank through the circular motion of the lower connecting pipe. Therefore, this device is suitable for the use of different types of additives, and the device has high applicability and practicality. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Please see Figure 1-4 In this embodiment of the present invention, a special asphalt mixing machine includes a mixing tank 1 and a storage tank 7. The bottom of the mixing tank 1 is provided with multiple support legs 2. A feed inlet 16 is provided on one side of the mixing tank 1. A circular plate 4 is rotatably mounted on the top of the mixing tank 1, and a toothed ring 3 is fixedly mounted on the top of the circular plate 4. An annular bottom plate 11 is fixedly fitted onto the upper part of the outer surface of the mixing tank 1. A U-shaped frame 9 is provided on the top of the annular bottom plate 11, and the storage tank 7 is located on the top of the U-shaped frame 9. The bottom of the storage tank 7... A material hopper with a downward-sloping opening is provided. A discharge pipe 20 is provided at the bottom of the material hopper. An upper connecting pipe 15 is rotatably sleeved on the outside of the discharge pipe 20. The top end of the upper connecting pipe 15 is rotatably connected to the inner top wall of the U-shaped frame 9. The bottom end of the upper connecting pipe 15 is connected to a conveying inclined pipe 8 through a connecting bend A. The other end of the conveying inclined pipe 8 is connected to a lower connecting pipe 10 through a connecting bend B. The lower connecting pipe 10 passes through the circular plate 4 and communicates with the interior of the mixing tank 1. The lower connecting pipe 10 is fixedly connected to the circular plate 4.

[0022] A support rod 19 is fixedly installed in the upper connecting pipe 15 along the horizontal direction. A feeding auger 21 is rotatably installed at the top center of the support rod 19. The feeding auger 21 passes through the discharge pipe 20 and extends into the interior of the material hopper.

[0023] The top of the annular base plate 11 is provided with a fixed seat 12, and the top of the fixed seat 12 is provided with a drive motor 13. The output shaft of the drive motor 13 is connected to a drive gear 5, and the drive gear 5 is meshed with the gear ring 3.

[0024] A rotating shaft 17 is provided at the bottom center of the circular plate 4, and multiple stirring rods 18 are provided on the outside of the rotating shaft 17. When the circular plate 4 rotates, it can drive the rotating shaft 17 to rotate, which in turn drives the multiple stirring rods 18 to rotate, so as to carry out stirring operations on the material in the mixing tank 1.

[0025] A support column 14 is provided at the top center of the circular plate 4. The top end of the support column 14 is fixedly connected to the outer surface of the conveying inclined pipe 8. The support column 14 is provided to reinforce the position of the conveying inclined pipe 8, the upper connecting pipe 15 and the lower connecting pipe 10, so as to stabilize the connection between them and the circular plate 4 and improve the stability of the conveying inclined pipe 8 and the upper connecting pipe 15 as the circular plate 4 rotates.

[0026] The top of the storage hopper 7 is equipped with a top cover 6 that is movable via a hinge, and the top of the top cover 6 is equipped with a handle. The modifier will not be used up quickly and may need to be stored in the storage hopper 7 for mixing different batches of asphalt. Therefore, when the modifier is stored in the storage hopper 7, the top cover 6 can prevent external contaminants from falling into the storage hopper 7 and ensure the cleanliness of the modifier.

[0027] An installation opening is provided at the top center of the U-shaped frame 9, and the storage bucket 7 is fixedly embedded in the installation opening.

[0028] In this device, the storage tank 7 is used to hold the modifier. Specifically, during use, the drive motor 13 drives the drive gear 5 to rotate. Through meshing, this drives the gear ring 3 and the circular plate 4 to rotate together, which in turn drives the lower connecting pipe 10, the conveying inclined pipe 8, and the upper connecting pipe 15 to rotate as well. That is, the feeding auger 21 in the upper connecting pipe 15 also rotates. With the material hopper at the bottom of the storage tank 7, the modifier can be evenly conveyed downwards. The modifier is conveyed through the upper connecting pipe 15 and the conveying inclined pipe 8 to the lower connecting pipe 10. The lower connecting pipe 10 is embedded in the circular plate 4 and moves in a circular motion with the circular plate 4. Thus, the modifier discharged through the lower connecting pipe 10 can be evenly dispersed from the top of the mixing tank 1, ensuring rapid, thorough, and uniform mixing with the asphalt, and improving the efficiency of the process. The rotating disc 4 also drives the rotating shaft 17 to rotate, which in turn drives multiple stirring rods 18 to rotate, thus stirring the material in the mixing tank 1. This device can achieve both asphalt mixing and uniform feeding of the modifier through a single drive source. It is worth mentioning that the feeding auger 21 is mainly used to transport fixed powdered or latex-like modifiers, while liquid modifiers can flow downwards through the gap between the auger blades and the inner wall of the discharge pipe 20. The feeding auger 21 also provides a certain buffering effect for the liquid. Similarly, the liquid modifier can also be evenly dispersed into the mixing tank 1 through the circularly moving lower connecting pipe 10. Therefore, this device is suitable for the use of different types of modifiers, and has high applicability and practicality.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
