Description

Technical Field

[0001] This invention relates to the field of asphalt processing technology, and in particular to an asphalt modified mixing machine and its usage method. Background Technology

[0002] In the production of asphalt modified materials, traditional mixers present several significant technical challenges. These challenges directly impact production efficiency, material mixing uniformity, and the cleanliness of the production environment. Firstly, traditional mixers have limitations in raw material input and mixing. Typically, they only have one feed inlet and a relatively simple mixing method, making it difficult to achieve thorough and uniform mixing of different types of raw materials in a short time. This not only reduces production efficiency but may also lead to unstable quality of the mixture, affecting the overall performance of the asphalt modified materials. Secondly, material blockage and dust pollution are another major problem faced by traditional mixers. During mixing, materials easily adhere to the inner walls of the agitator or conveying pipes, causing blockages and affecting the smooth flow of materials. Simultaneously, the dust generated during mixing is difficult to collect and treat effectively, easily polluting the production environment and endangering workers' health. Furthermore, traditional mixers are often large and complex in design, with inflexible connections and transmission methods between components, resulting in poor stability during operation and difficulty in routine cleaning and maintenance. This not only increases maintenance costs and time but also limits the equipment's applicability and flexibility. Summary of the Invention

[0014] A method for using an asphalt modification mixer includes the following steps: Asphalt is conveyed from a feed section one into a mixing bin, and then gradually flows downward through the uppermost guide section. When it falls to the middle guide section, a modifier is conveyed from the feed section two to the middle guide section. At this time, the asphalt and modifier continuously flow in the guide section, thereby achieving a mixing effect. During mixing, the guide section is continuously patted by a tapping section to vibrate it, further ensuring the mixing effect of the asphalt and modifier during flow. Finally, the mixture falls to the top of the inner bottom wall of the mixing bin and is stirred by a mixing section to ensure the mixing effect.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Reference Figures 1-9An asphalt modification mixing machine mainly consists of a mixing tank 1. The top of the mixing tank 1 is equipped with a feed section 2 for initial material addition. Three sets of guide sections 3 are arranged alternately inside the mixing tank 1 to enhance material flow and mixing. A second feed section 4 is located at the top of the second set of guide sections 3 for adding a second or subsequent raw material. A tapping section 5 is installed at the bottom of each guide section 3 and the second feed section 4. When the tapping section rotates, it taps the bottom of the guide section, helping the material fall and preventing blockage. An agitator 6 is installed on the inner wall of the mixing tank 1, below the guide sections 3, for mixing the materials. A dust extraction section 7 is installed on one side of the mixing tank 1 to collect dust within the mixing tank. The dust is extracted through the dust extraction section 7 and stored in a storage tank 8. On the other side of the mixing box 1, a transmission unit 9 is installed to drive the material extraction unit 7 to extract dust. Through the above structure, the mixer achieves uniform mixing of raw materials, effectively reduces dust pollution, and improves work efficiency. The material guide unit 3 includes a sliding seat 31 installed at the mixing box 1. The sliding seat 31 has an inner cavity 311, and an electric heating plate 312 is installed in the inner cavity 311. The electric heating plate 312 is used to heat the material flowing at the sliding seat 31. By setting the electric heating plate 312, the material flowing at the sliding seat 31 can be laid flat, so that the heating effect is more uniform. The surface of the mixing box 1 is provided with a material removal door 11 to facilitate the removal of the mixed material.

[0033] In this invention, the feeding section 2 includes a guide seat 21 installed on the top of the mixing tank 1. The top of the guide seat 21 has a cavity 22, and the top of the cavity 22 has a feed inlet 23. A rotatable drive shaft 24 is installed inside the cavity 22, and drive blades 25 are mounted on the surface of the drive shaft 24. When the raw material enters the cavity 22 from the feed inlet 23, the drive shaft 24 drives the drive blades 25 to rotate, uniformly feeding the raw material into the mixing tank 1. This design ensures that the raw material can enter the mixing tank uniformly and continuously, avoiding problems such as blockage and uneven distribution of raw materials.

[0034] In this invention, a stirring motor 61 is mounted on the surface of the mixing tank 1. A stirring rod 62 is mounted on the output end of the stirring motor 61. The stirring rod 62 is rotatably connected to the inner wall of the mixing tank 1 via a bearing and extends through to the outside of the mixing tank 1. The surface of the stirring rod 62 is equipped with arc-shaped stirring blades 63 for lifting materials. Multiple material leakage grooves 64 are provided on the stirring blades 63 to facilitate better mixing of materials. The stirring motor 61 drives the stirring rod 62 and stirring blades 63 to rotate, achieving uniform mixing of materials. The design of the material leakage grooves 64 further improves the mixing effect.

[0035] In this invention, the tapping part 5 includes a rotating rod 51 installed on the inner wall of the mixing box 1. The rotating rod 51 is rotatably connected to a tapping rod 52 via a rotating shaft, and the tapping rod 52 contacts the bottom of the sliding material seat 31. A belt component 53 is installed between the two rotating rods 51, and a belt component 54 is installed between the rotating rods 51 and the drive shaft 24. When the drive shaft 24 rotates, the belt component 54 drives the rotating rods 51 to rotate, which in turn drives the tapping rod 52 to tap the bottom of the sliding material seat 31. This design ensures that the tapping part 5 can work with the rotation of the drive shaft 24, effectively preventing material blockage at the bottom of the sliding material seat 31.

[0036] In this invention, the extraction unit 7 includes a temporary storage cylinder 71 installed on the side of the mixing tank 1. A piston rod 72 is inserted into the inner wall of the temporary storage cylinder 71, and a connecting spring 73 is installed between the piston rod 72 and the inner wall of the temporary storage cylinder 71. An extraction pipe 74 is installed at the top of the temporary storage cylinder 71, which is inserted into the mixing tank 1, and has multiple extraction heads 75 on its surface. A discharge pipe 76 is also installed at the top of the temporary storage cylinder 71, which is inserted into the air storage tank 8. Both the extraction pipe 74 and the discharge pipe 76 are equipped with one-way valves. When the piston rod 72 moves under the drive of the transmission unit 9, the dust in the mixing tank 1 is drawn into the temporary storage cylinder 71 through the extraction heads 75, and then discharged into the air storage tank 8 through the discharge pipe 76, thus achieving effective collection and storage of dust.

[0037] In this invention, the material guiding unit 3 includes a sliding seat 31 installed on the inner wall of the mixing box 1. A reset member 32 is installed at the bottom of the sliding seat 31, and a scraper 33 is slidably connected to the inner wall of the sliding seat 31. The reset member 32 is used to reset the scraper 33. A baffle plate 34 is installed at the top of the sliding seat 31, and a discharge groove 35 is provided at the bottom of the baffle plate 34. When the scraper 33 moves under material pressure, the reset component 32 resets it, pushing the material adhering to the inner wall of the slide seat 31 through the discharge chute 35. This design ensures that the material can be smoothly discharged from the slide seat 31, reducing material residue in the mixing box. A guide rod 36 is installed on the inner wall of the slide seat 31, and the scraper 33 is connected to the guide rod 36. A limit piece 37 is installed at the end of the guide rod 36 to limit the scraper 33. The design of the guide rod 36 and the limit piece 37 ensures the stability and accuracy of the scraper 33 during movement. The reset component 32 includes a connecting piece 321 installed at the bottom of the slide seat 31, a connecting piece 323 installed on the surface of the scraper 33, and a reset spring 322 installed between the connecting piece 321 and the connecting piece 323. The design of the reset spring 322 ensures that the scraper 33 can quickly reset after being subjected to material pressure, pushing the material out.

[0038] In this invention, the transmission unit 9 includes a half gear 91 mounted on the surface of the stirring rod 62, a connecting rod 93 mounted on the bottom of the piston rod 72, and a rack 92 mounted on the top of the connecting rod 93. The rack 92 meshes with the half gear 91. When the stirring rod 62 rotates, the half gear 91 drives the rack 92 and the connecting rod 93 to move, thereby driving the piston rod 72 to move within the temporary storage cylinder 71. This design achieves linkage between the stirring unit 6 and the material extraction unit 7, improving the working efficiency and automation level of the mixer.

[0039] A method of using an asphalt modification mixer includes the following steps: Asphalt is conveyed from the feed section 2 into the mixing bin 1, and then gradually flows downward through the uppermost guide section 3. When it falls to the middle guide section 3, the modifier is conveyed from the feed section 4 to the middle guide section 3 through the feed section 4. At this time, the asphalt and modifier continuously flow in the guide section 3, thereby achieving the effect of mixing. During the mixing, the guide section 3 is continuously patted by the beater 5, thereby achieving the effect of vibration in the guide section 3, further ensuring the mixing effect of asphalt and modifier during flow. Then, the mixture falls to the top of the inner bottom wall of the mixing bin 1 and is stirred by the stirring section 6, thereby ensuring the mixing effect. Finally, the transmission section 9 drives the extraction section 7 to extract the dust generated in the mixing bin 1 during vibration, mixing and stirring into the storage tank 8 for subsequent recycling and treatment.

[0040] The specific working principle of this invention is as follows: The operator puts the raw material into the cavity 22 through the feed port 23 of the feeding section 2. The drive shaft 24 starts to rotate under the action of the drive device, driving the drive blades 25 to evenly feed the raw material into the mixing box 1. At the same time, the stirring motor 61 starts, driving the stirring rod 62 and stirring blades 63 to rotate, and initially mixing the raw material entering the mixing box 1. After the initial mixing, the raw material enters the sliding seat 31 of the guide section 3. The scraper 33 slides along the guide rod 36 under the material pressure. When the material pressure decreases or disappears, the return spring 322 pushes the scraper 33 to return to its original position, and the material adhering to the inner wall of the sliding seat 31 is discharged through the discharge chute 35. During this process, the rotating rod 51 of the tapping section 5 rotates in linkage with the drive shaft 24 through the belt component 2 54, driving the tapping rod 52 to tap the bottom of the sliding seat 31 to prevent material blockage. When it is necessary to add a second or subsequent raw material... When the mixing process is complete, the operator feeds the raw materials into the mixing tank 1 through the feeding section 2 4. These raw materials are further mixed with the raw materials mixed initially under the action of the stirring blades 63. During the mixing process, the dust generated in the mixing tank 1 is sucked into the storage cylinder 71 through the suction head 75 of the suction section 7. When the stirring rod 62 rotates, the half gear 91 meshes with the rack 92, driving the connecting rod 93 and the piston rod 72 to move in the storage cylinder 71. The movement of the piston rod 72 discharges the dust in the storage cylinder 71 into the air storage tank 8 through the discharge pipe 76 for storage. When the raw materials are mixed to the predetermined requirements, the stirring motor 61 and the transmission device are turned off, and the discharge port at the bottom of the mixing tank 1 is opened. Although not explicitly mentioned in the claims, the mixing machine usually has a discharge device to discharge the mixed material. After completing a mixing task, the mixing machine is cleaned and maintained as necessary, including cleaning the dust in the air storage tank 8 and checking the wear of each component.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
