Description

Technical Field

[0001] This utility model patent relates to the technical field of stirring structures, specifically to a stirring structure with alternating electromagnetic field for preparing low-carbon, odorless asphalt. Background Technology

[0002] With the development of road construction, the requirements for asphalt performance are increasing. As an environmentally friendly and high-performance asphalt material, the mixing technology in the preparation process of low-carbon, odorless asphalt has become a key link.

[0003] In existing technologies, traditional mixing equipment and methods, such as mechanical mixing, can easily lead to insufficient or uneven mixing in certain areas when processing modified warm mix agents and base asphalt. This is because the viscosity, density, and other characteristics of the modified warm mix agent differ from the physical and chemical properties of the base asphalt, which in turn affects the final quality and performance of the low-carbon, odorless asphalt.

[0004] Moreover, the modified warm mix additive contains nanoparticles, which are prone to agglomeration during conventional mixing, thus failing to fully exert the modifying effect of nanoparticles on asphalt and limiting the improvement of the performance of low-carbon, odorless asphalt.

[0005] Furthermore, to achieve good mixing results, traditional mixing equipment often requires longer mixing times and higher energy consumption. This not only increases production costs but also reduces production efficiency, making it difficult to meet the needs of large-scale production. Utility Model Content

[0006] The purpose of this invention is to provide a mixing structure with alternating electromagnetic field for preparing low-carbon, odorless asphalt, aiming to solve the problem of uneven mixing of modified warm mix agent and base asphalt in the prior art.

[0007] This invention is achieved by a stirring structure for preparing low-carbon, odorless asphalt with an alternating electromagnetic field. The structure includes a stirring drum for mixing a modified warm mix agent with base asphalt to form low-carbon, odorless asphalt, and an alternating magnetic field generator for generating the alternating magnetic field. The modified warm mix agent contains nanoparticles coated with iron(III) oxide. The alternating magnetic field generator surrounds the outer circumference of the stirring drum in a closed circumferential loop, with an annular gap between the alternating magnetic field generator and the outer circumference of the stirring drum.

[0008] Furthermore, the alternating magnetic field generator includes an annular cylinder that surrounds and forms a magnetic field region, a stirring cylinder that is placed in the magnetic field region, an annular gap that is formed between the annular cylinder and the stirring cylinder, and a coil that generates an alternating magnetic field is provided in the annular cylinder.

[0009] Furthermore, the annular cylinder has an annular cavity arranged around the outer periphery of the stirring cylinder, and the coil is placed in the annular cavity and arranged around the circumference of the annular cavity.

[0010] Furthermore, the outer periphery of the stirring cylinder is provided with an annular frame, and the middle part of the annular frame has a central area arranged vertically through it. The annular cylinder is placed in the central area and connected to the annular frame.

[0011] Furthermore, a ring-shaped support ring is formed at the lower part of the central area, and the bottom of the annular cylinder abuts against the support ring so that the annular cylinder surrounds the outer periphery of the middle part of the stirring cylinder.

[0012] Furthermore, the bottom of the annular frame has a bottom plate located below the support ring, and the bottom of the stirring cylinder abuts against the bottom plate.

[0013] Furthermore, the mixing drum has a mixing chamber for containing modified odor-neutralizing asphalt, and the mixing drum has a bottom section located between the support ring and the bottom plate. The bottom section is provided with an outlet for discharging the modified odor-neutralizing asphalt, and the outlet is connected to the mixing chamber.

[0014] Furthermore, the stirring chamber is provided with a stirring shaft, which extends along the depth direction of the stirring chamber; the outer periphery of the stirring shaft is provided with multiple stirring blades, which are staggered along the circumferential and axial directions of the stirring shaft.

[0015] The stirring shaft drives multiple stirring blades to rotate and stir, and the multiple stirring blades stir the modified warm mix agent and the base asphalt to form low carbon odorless asphalt.

[0016] Furthermore, the stirring blades are arranged at an angle, and the stirring blades are provided with a plurality of through holes that penetrate the stirring blades. The through holes are flat strips and extend along the length direction of the stirring blades.

[0017] Furthermore, the outer periphery of the through hole has an inwardly arranged outer peripheral sidewall, which protrudes inward to form multiple pointed protrusions. The multiple pointed protrusions are arranged at intervals along the length direction of the inner sidewall, and a triangular groove area is formed between adjacent pointed protrusions.

[0018] Compared with the prior art, the mixing structure for preparing low-carbon, odorless asphalt with an alternating electromagnetic field provided by this utility model acts on the modified warm mix agent containing nanoparticles coated with iron(III) oxide through an alternating magnetic field generator. This causes the nanoparticles to move and interact under the action of the magnetic field, which drives the modified warm mix agent to form a dynamic flow field in the mixing drum, thereby enhancing the mixing efficiency between it and the base asphalt and achieving a more uniform mixing effect.

[0019] Furthermore, the alternating magnetic field generator surrounds the outer periphery of the mixing drum in a closed circumferential loop, with an annular gap between them. This layout ensures that the alternating magnetic field can effectively penetrate into the mixing drum and that the magnetic field can act on the material inside the mixing drum in an all-round and uniform manner, thereby further improving the uniformity and efficiency of mixing.

[0028] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0029] A mixing structure for preparing low-carbon, odorless asphalt with an alternating electromagnetic field includes a mixing drum 100 for mixing a modified warm mix agent with base asphalt to form low-carbon, odorless asphalt, and an alternating magnetic field generator for generating an alternating magnetic field. The modified warm mix agent contains nanoparticles coated with iron(III) oxide. The alternating magnetic field generator surrounds the outer periphery of the mixing drum 100 in a closed circumferential loop, and there is an annular gap 201 between the alternating magnetic field generator and the outer periphery of the mixing drum 100.

[0030] The mixing structure for preparing low-carbon, odorless asphalt with an alternating electromagnetic field provided above uses an alternating magnetic field generated by an alternating magnetic field generator to act on the modified warm mix agent containing nanoparticles coated with iron(III) oxide. This causes the nanoparticles to move and interact under the influence of the magnetic field, which in turn drives the modified warm mix agent to form a dynamic flow field within the mixing drum 100, enhancing its mixing efficiency with the base asphalt and thus achieving a more uniform mixing effect.

[0031] Furthermore, the alternating magnetic field generator surrounds the outer periphery of the mixing drum 100 and forms a closed circumferential loop. At the same time, an annular gap 201 is set between the two. This layout ensures that the alternating magnetic field can effectively penetrate into the interior of the mixing drum 100 and that the magnetic field can act on the material inside the mixing drum 100 in an all-round and uniform manner, thereby further improving the uniformity and efficiency of mixing.

[0032] In this embodiment, the alternating magnetic field generator includes an annular cylinder 200, which surrounds and forms a magnetic field region. A stirring cylinder 100 is placed in the magnetic field region, and an annular gap 201 is formed between the annular cylinder 200 and the stirring cylinder 100. A coil 202 for generating an alternating magnetic field is provided in the annular cylinder 200.

[0033] When the annular cylinder 200 generates a stable alternating magnetic field and places the mixing drum 100 in the magnetic field region, the magnetic field can act uniformly on the mixture of modified warm mix agent and base asphalt in the mixing drum 100. The alternating magnetic field interacts with the nanoparticles coated with iron oxide in the modified warm mix agent, driving the nanoparticles to move. This causes the modified warm mix agent to form a dynamic flow field in the mixing drum 100, enhancing its mixing efficiency with the base asphalt, thereby improving the mixing effect and ensuring the quality and performance of low-carbon, odorless asphalt.

[0034] In this embodiment, the annular cylinder 200 has an annular cavity 203, which is arranged around the outer periphery of the stirring cylinder 100. The coil 202 is placed in the annular cavity 203 and is arranged around the annular cavity 203 in a circumferential manner.

[0035] By placing the coil 202 in the annular cavity 203 and arranging it around the circumference, the alternating magnetic field generated by the coil 202 can be more evenly distributed around the entire stirring drum 100. This arrangement improves the utilization efficiency of the magnetic field and ensures that the magnetic field can act on the material in the stirring drum 100 in all directions, further enhancing the uniformity and efficiency of the stirring.

[0036] In this embodiment, an annular frame 204 is provided on the outer periphery of the stirring cylinder 100. The annular frame 204 has a central area arranged vertically in the middle. The annular cylinder 200 is placed in the central area and connected to the annular frame 204.

[0037] The ring frame 204 provides a stable support structure for the ring cylinder 200, ensuring that the ring cylinder 200 can be firmly wrapped around the outer periphery of the mixing drum 100. The vertical arrangement of the central area allows the mixing drum 100 to maintain good ventilation and operability under the support of the ring frame 204. This not only improves the overall stability of the equipment, but also provides a strong guarantee for the uniform distribution of the magnetic field.

[0038] In this embodiment, a support ring 205 is formed in the lower part of the central area, and the bottom of the annular cylinder 200 abuts against the support ring 205 so that the annular cylinder 200 surrounds the outer periphery of the middle part of the stirring cylinder 100.

[0039] This enhances the connection stability between the annular cylinder 200 and the mixing drum 100, ensuring that the annular cylinder 200 will not shift or shake during operation, thereby optimizing the range of the magnetic field and enabling the magnetic field to act more precisely on the material inside the mixing drum 100, thus improving the mixing effect.

[0040] In this embodiment, the bottom of the ring frame 204 has a bottom plate 101, which is located below the support ring 205, and the bottom of the stirring cylinder 100 abuts against the bottom plate 101.

[0041] In this way, the bottom plate 101 can provide stable bottom support for the mixing drum 100, ensuring that the mixing drum 100 remains vertically stable during operation. At the same time, the cooperation between the bottom plate 101 and the support ring 205 also enhances the rigidity of the entire mixing structure, improving the load-bearing capacity and operational stability of the equipment.

[0042] In this embodiment, the mixing drum 100 has a mixing chamber 102 for containing modified odorless asphalt. The mixing drum 100 has a bottom section located between the support ring 205 and the bottom plate 101. The bottom section is provided with an outlet for discharging the modified odorless asphalt, and the outlet is connected to the mixing chamber 102.

[0043] This ensures that materials can be discharged smoothly, avoiding accumulation and waste within the mixing drum 100, and improving production efficiency.

[0044] In this embodiment, a stirring shaft 103 is provided in the stirring chamber 102, and the stirring shaft 103 extends along the depth direction of the stirring chamber 102; a plurality of stirring blades 104 are provided on the outer periphery of the stirring shaft 103, and the plurality of stirring blades 104 are staggered along the circumferential and axial directions of the stirring shaft 103.

[0045] The mixing shaft 103 drives multiple mixing blades 104 to rotate and mix, and the multiple mixing blades 104 mix the modified warm mix agent with the base asphalt to form low carbon odorless asphalt.

[0046] By arranging multiple mixing blades 104 in a staggered manner along the circumference and axial direction of the mixing shaft 103, a multi-layered and multi-angle mixing effect can be formed, which enhances the mixing effect of the modified warm mix agent and the base asphalt. This combination of mechanical mixing and alternating magnetic field-assisted mixing further improves the uniformity and efficiency of mixing, ensuring the quality of low-carbon, odorless asphalt.

[0047] In this embodiment, the stirring blade 104 is arranged in an inclined manner, and the stirring blade 104 is provided with a plurality of through holes 105 penetrating the stirring blade 104. The through holes 105 are flat strips and extend along the length direction of the stirring blade 104.

[0048] The inclined arrangement of the stirring blades 104 can generate a more complex fluid flow path, enhance the shearing and mixing effect between materials, and increase the stirring intensity of the stirring blades 104 through the through hole 105, so that the material is subjected to stronger shearing force when passing through the through hole 105, further refining the material particles and improving the uniformity of mixing.

[0049] In this embodiment, the outer periphery of the through hole 105 has an inwardly arranged outer peripheral sidewall. The outer peripheral sidewall protrudes inward to form a plurality of pointed protrusions 106. The plurality of pointed protrusions 106 are arranged at intervals along the length direction of the inner sidewall, and a triangular groove area is formed between adjacent pointed protrusions 106.

[0050] When the material passes through the through hole 105, the pointed protrusion 106 can generate a local high-intensity shear force on the material, which further breaks and disperses the material particles. The triangular groove area provides more paths and space for the flow of the material, enhancing the collision and mixing opportunities between materials, thereby helping to improve the fineness of the mixing and ensuring that the modified warm mix agent and the base asphalt can be uniformly mixed at the micro level.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
