Description

Technical Field

[0001] This invention relates to the field of asphalt heating technology, and more particularly to a base asphalt heating device. Background Technology

[0002] Currently, base asphalt heating mostly employs a fixed heating tank structure, relying on electric or gas heating to raise the temperature of the asphalt inside the tank. Common equipment is usually equipped with simple stirring blades, which achieve a certain degree of mixing through rotation. However, its stirring direction is unidirectional and its range of action is limited, making it difficult to achieve sufficient flow of materials at different levels and radial positions within the tank. Especially when processing high-viscosity asphalt, traditional stirring methods easily create heating dead zones, leading to localized excessively high or low temperatures, which affects the overall quality and performance stability of the asphalt.

[0003] Publication number CN 221951052 U The patent document discloses a heating and stirring device for preparing asphalt. It includes a preparation box with a preparation chamber inside, a stirring box inside the preparation box, a stirring chamber inside the stirring box, a cover on the top of the preparation box, a filter screen on the side of the stirring chamber near the bottom of the stirring box, a first drive motor at the bottom of the stirring box, a rotating shaft on the side of the drive motor facing the top of the stirring box, multiple stirring rods distributed vertically on the rotating shaft, sliding components corresponding to the bottom of the preparation box and the bottom of the stirring box, a shaking component inside the preparation box to shake the stirring box, at least one discharge port at the bottom of the preparation box, and support feet at the four corners of the bottom of the preparation box. This invention reduces heat loss from the stirring box by placing the preparation box outside the stirring box, and increases the mixing area by shaking the stirring box from side to side while stirring inside, thus achieving uniform mixing.

[0004] In the aforementioned solutions and existing technologies, asphalt heating devices often lack real-time temperature monitoring and control capabilities, and cannot dynamically adjust the stirring intensity or direction according to the actual temperature distribution inside the tank. On the one hand, the stirring structure is usually at a fixed angle, which cannot adapt to the material conveying requirements of different viscosities or heating stages; on the other hand, the material is often added into the heating tank all at once, which easily leads to accumulation and uneven heating. In addition, asphalt easily generates dust and volatiles during feeding and heating, and most existing equipment is not equipped with an effective collection and treatment system, which not only wastes raw materials but also pollutes the working environment. These problems limit further improvement in heating efficiency and product quality; therefore, this invention proposes a matrix asphalt heating device to solve this problem. Summary of the Invention

[0015] The beneficial effects of this invention are as follows: 1. In this invention, a base asphalt heating device is described, which loads raw materials into a feeding hopper and starts a feeding motor to drive a rotating grid to rotate, so that the mesh on the rotating grid is intermittently connected with the feed inlet on the feeding grid, thereby allowing the raw materials to gradually enter the heating tank, and then starts an electric heating tube to heat the asphalt raw materials in the heating tank. 2. In this invention, the matrix asphalt heating device drives the drive motor to rotate the active gear. The active gear, through meshing with the driven magnetic force, drives the positioning cylinder to rotate. The positioning cylinder drives the mounting cylinder to rotate. The mounting cylinder drives the inclined blades and arc-shaped blades to perform circumferential motion. When the inclined blades on both sides rotate, they convey the raw material to both sides, realizing the horizontal conveying of the raw material. When the inclined blades rotate, they push the raw material close to the positioning cylinder to the outside, making the raw material radially conveyed. They also bring the material close to the inner wall of the tank into the inside of the rotating cylinder through the through hole, realizing the circulatory conveying of the raw material. This allows the raw material to be fully mixed and exchange heat in different directions, thereby improving the heating uniformity. 3. In this invention, the matrix asphalt heating device monitors the asphalt temperature at different locations within the heating tank using a first temperature sensor and a second temperature sensor. When the temperature difference detected by the second temperature sensors on the left and right sides exceeds a preset value, the controller controls the electric push rod on the left side to move the cylinder on the left side horizontally, which in turn moves the mounting ring and the spiral cylinder horizontally. The fixed cylinder, in cooperation with the limiting strip, causes the spiral cylinder to rotate synchronously with the positioning cylinder. Simultaneously, the spiral cylinder, through the cooperation of the spiral groove and the mounting plate, causes the mounting plate to rotate. The mounting plate causes the first connecting shaft to rotate. The first connecting shaft, through the meshing of the active bevel gear and the small bevel gear, causes the rotating shaft and the inclined blade to rotate, thereby adjusting the angle of the inclined blade and increasing the angle of attack of the inclined blade. This increases the horizontal conveying capacity generated by the inclined blade during its circular motion and reduces the temperature difference of the raw materials at different locations on the left and right sides. 4. In this invention, when the difference between the temperature value monitored by the first temperature sensor and the temperature value of the second stable sensor exceeds a preset value, the controller controls the electric push rod on the right side to start, the mounting plate on the right side and the second connecting shaft to rotate. The second connecting shaft drives multiple screws to rotate through the meshing of the small gear and the large gear. The screws drive the moving frame to move left and right through the threaded engagement with the moving frame. The moving frame drives multiple spiral columns to rotate through the engagement of the spiral hole and the spiral strip. The spiral columns drive the mounting shaft and the arc blades to rotate, thereby increasing the workpiece of the arc blades and increasing the speed of radial conveying of the raw materials. This allows the raw materials in the inner and outer rings of the heating tank to be more fully mixed and heat exchanged, thereby improving the temperature uniformity of the raw materials inside and outside the heating tank. 5. In this invention, the matrix asphalt heating device extracts air from the collection box by starting a negative pressure fan, allowing the air mixed with raw material powder and dust at the top of the feed hopper to enter the collection box through the collection pipe, rotating pipe, air distribution plate, and air distribution holes. The air is then filtered and collected through multiple filter screens, achieving the recycling of solid materials. Simultaneously, as the air passes through the rotating pipe, it drives the rotating pipe and air distribution plate to rotate by pushing the spiral blades, thereby ensuring that the air discharged from the air distribution holes is evenly distributed on the filter screens, avoiding filtration in one area, making full use of the filtration area of ​​the filter screens, and reducing environmental pollution. 6. In this invention, the matrix asphalt heating device achieves gradual and uniform feeding of raw materials through a feeding mechanism, avoiding uneven heating caused by feeding a large amount of material at once. A rotating mechanism drives inclined and arc-shaped blades in circular motion, achieving bidirectional conveying of raw materials in both horizontal and radial directions, promoting material circulation and heat exchange within the tank, and significantly improving heating uniformity. The device is equipped with multiple temperature sensors to monitor the asphalt temperature at different locations in real time. When the temperature difference exceeds a preset range, the controller automatically activates the adjustment mechanism, driving a bevel gear or gear set structure via an electric push rod to dynamically adjust the blade angle or actuation intensity, thereby enhancing the material conveying capacity in the corresponding direction and effectively reducing the temperature difference within the tank. Furthermore, a collection mechanism, in conjunction with a negative pressure fan and filter screen, recovers dust and raw material powder, reducing environmental pollution and improving raw material utilization. The overall structure is rationally designed, combining high heating efficiency, temperature controllability, and environmental friendliness. Attached Figure Description

[0028] In this embodiment, during use, the raw material is loaded into the feed hopper 301 and the feed motor 304 is started to drive the rotating grid 306 to rotate, so that the mesh on the rotating grid 306 is intermittently connected with the feed port on the feed grid 302, thereby allowing the raw material to gradually enter the heating tank 1, and the electric heating tube 105 is started to heat the asphalt raw material in the heating tank 1. Inclined blades 501 are arranged around the mounting cylinder 401 and are initially in an inclined state. The drive motor 407 is started to drive the drive gear 406 to rotate. The drive gear 406 drives the positioning cylinder 404 to rotate through meshing with the driven gear 405. The positioning cylinder 404 drives the mounting cylinder 401 to rotate. The mounting cylinder 401 drives the inclined blades 501 and the arc blades 601 to perform circular motion. When the inclined blades 501 on both sides rotate, they convey the raw materials to both sides through their inclined surfaces to achieve horizontal conveying of the raw materials. When the inclined blades 501 rotate, they push the raw materials close to the positioning cylinder 404 to the outside and let the material inside the rotating cylinder 402 enter the outside of the rotating cylinder 402 through the through hole 4021 to achieve the circulation conveying of the raw materials. This allows the raw materials to be fully mixed and exchange heat in different directions, thereby improving the heating uniformity. The asphalt temperature at different locations within the heating tank 1 is monitored by a first temperature sensor 103 and a second temperature sensor 104. When the temperature difference detected by the second temperature sensors 104 on the left and right sides exceeds a preset value, the controller 8 controls the electric push rod 702 on the left side to move the cylinder 703 on the left side horizontally, which in turn moves the mounting ring 707 and the spiral cylinder 704 horizontally. The fixing ring, in cooperation with the limit strip, causes the spiral cylinder 704 to rotate synchronously with the positioning cylinder 404. At the same time, the spiral cylinder 704 connects with the mounting plate 70 through the spiral groove 7041. The cooperation of 5 drives the mounting plate 705 to rotate, the mounting plate 705 drives the first connecting shaft 505 to rotate, and the first connecting shaft 505 drives the rotating shaft 502 and the inclined blade 501 to rotate through the meshing of the driving bevel gear 504 and the driven bevel gear, thereby adjusting the angle of the inclined blade 501, increasing the angle of attack of the inclined blade 501, thereby increasing the horizontal conveying capacity generated by the inclined blade 501 when it performs circular motion, so that the raw materials can be fully mixed, so that the local temperature of the raw materials is too high or too low, thereby reducing the temperature difference between the raw materials at different positions on the left and right. When the difference between the temperature value monitored by the first temperature sensor 103 and the temperature value monitored by the second temperature sensor exceeds a preset value, the controller 8 activates the electric push rod 702 on the right side. The electric push rod 702 drives the cylinder 703 on the right side to move horizontally, and also drives the mounting ring 707 and the spiral cylinder 704 to move horizontally. The mounting plate 705 on the right side and the second connecting shaft 603 rotate. The second connecting shaft 603 drives multiple screws 607 to rotate through the meshing of the small gear 605 and the large gear 606. The screws 607 drive the moving frame 604 to move through the threaded engagement with the moving frame 604. The moving frame 604 drives multiple spiral columns 608 to rotate through the engagement of the spiral hole and the spiral strip. The spiral columns 608 drive the mounting shaft 602 and the arc blade 601 to rotate, thereby increasing the workpiece of the arc blade 601 and improving the angle of attack for radial conveying of raw materials, making the process more efficient. The raw materials inside and outside the heating tank 1 can be more fully mixed and heat exchanged, thereby improving the temperature uniformity of the raw materials inside and outside the heating tank 1. By starting the negative pressure fan 207, the air in the collection box 201 is extracted, and the air mixed with raw material powder and dust at the top of the feed hopper 301 enters the collection box 201 through the collection pipe 202, rotating pipe 2082, air distribution plate 208 and air distribution hole 2081. It is then filtered and collected by multiple filter screens 2061 to realize the recycling of solid materials. At the same time, when the air passes through the rotating pipe 2082, it drives the spiral blades 2083 to drive the rotating pipe 2082 and air distribution plate 208 to rotate, so that the air brought out from the air distribution hole 2081 can be evenly distributed on the filter screen 2061, avoiding filtration in one area, making full use of the filtration area of ​​the filter screen 2061 and reducing environmental pollution.

[0029] In this embodiment, the electric heating tubes 105 are set in multiple groups, and each tube is individually temperature controlled to achieve constant temperature control of the raw materials. The electric heating tubes 105 adopt an elliptical bottom design, which not only achieves a large heat exchange area but also greatly reduces the heat load on the surface of the heat exchanger, so that the quality of the materials can be ensured when the equipment heats up rapidly.
