Description

Technical Field

[0001] This utility model relates to the technical field of asphalt concrete heaters, specifically to a heating device for asphalt concrete processing. Background Technology

[0002] Asphalt concrete, also known as asphalt concrete, is a mixture made by artificially selecting aggregates with a specific gradation, such as crushed stone or crushed gravel, stone chips or sand, and mineral powder, and mixing them with a certain proportion of road asphalt materials under strictly controlled conditions. During the processing of asphalt concrete, the asphalt needs to be heated to ensure thorough mixing with other substances.

[0003] The patent application number "CN215329167U" describes "a heating device for asphalt concrete processing." This utility model discloses a heating device for asphalt concrete processing, including an overall heater structure. The overall heater structure includes a heater main rod, with a heating spiral disc at the bottom and a vertical handle at the top. The heating spiral disc has a heating disc connector at the top. The heater power cord and the heater main rod are connected and fixed by a three-phase connector, which is a plug-in detachable structure. When the heater is not in use, the power cord can be detached and stored, avoiding frequent bending and damage at the base of the power cord, thus improving the service life of the power cord. At the same time, an adjustable heating disc height limit ring is nested on the outside of the heater main rod. Folding rods are provided on both sides of the height limit ring. The height of the heating disc height limit ring can be adjusted according to the height of the asphalt in the asphalt bucket, which is more conducive to the uniform heating of the asphalt, improves work efficiency, and prevents the heating spiral disc from touching the bottom.

[0004] The aforementioned patent addresses this issue. Furthermore, the heater's main rod is nested with a height-adjustable heating plate height-limiting ring. Folding rods are installed on both sides of the height-limiting ring, allowing for adjustment of the ring's height according to the asphalt level in the asphalt tank. This promotes more uniform heating of the asphalt, improves work efficiency, and prevents the heating spiral disc from hitting the bottom. However, traditional asphalt concrete processing heating devices lack a stirring mechanism to assist in enhancing the heating process, leading to uneven heating of the asphalt and aggregate. Adding a stirring mechanism to the heating device increases the contact area between the asphalt and aggregate, accelerating heat transfer and distribution, resulting in more uniform and efficient heating. Additionally, the addition of a self-cleaning tank component should be considered to ensure efficient operation and reduce maintenance requirements. 。 Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Example

[0031] Please see Figures 1-4 The present invention provides the following technical solution:

[0032] A heating device for asphalt concrete processing includes:

[0033] Main heating equipment 1;

[0034] The cleaning and stirring mechanism is located inside the main heating device 1. The cleaning and stirring mechanism includes a motor 2, an output shaft 3, a cooperating rotator 4, a rotating shaft 5, and a stirring and cleaning device 6. There are two rotating shafts 5 and two stirring and cleaning devices 6. The motor 2 is located on the upper side of the main heating device 1. The output shaft 3 is rotatably connected inside the motor 2. The cooperating rotator 4 is fixedly connected to the circumferential surface of the output shaft 3. Both rotating shafts 5 are rotatably connected inside the cooperating rotator 4. The two stirring and cleaning devices 6 are respectively fixedly connected to the lower ends of the two rotating shafts 5.

[0035] In a specific embodiment of this utility model, the cleaning and stirring mechanism is located inside the heating main equipment 1, aiming to achieve uniform heating and stirring of materials, while also having a cleaning function to ensure the cleanliness of the equipment interior and improve processing efficiency. The cleaning and stirring mechanism consists of a motor 2, an output shaft 3, a cooperating rotator 4, a rotating shaft 5, and a stirring and cleaning device 6. There are two rotating shafts 5 and two stirring and cleaning devices 6, forming a symmetrical arrangement to enhance the stirring and cleaning effect. The motor 2 is located on the upper side of the heating main equipment 1, serving as a power source. The output shaft 3 is rotatably connected inside the motor 2, and the cooperating rotator 4 is fixedly connected to the circumferential surface of the output shaft 3. The actuator 4 serves to transmit and distribute power. Both rotating shafts 5 are rotatably connected to the cooperating actuator 4. The rotational power of the motor 2 is transmitted to the rotating shafts 5 through gears 7, chains, or belts. The two stirring and cleaning devices 6 are fixedly connected to the lower ends of the two rotating shafts 5 respectively. When the rotating shafts 5 rotate under the drive of the cooperating actuator 4, the stirring and cleaning devices 6 also rotate, stirring the asphalt concrete in the heating main equipment 1. At the same time, its specially designed cleaning structure can effectively remove the residue on the inner wall and bottom of the equipment, preventing material from clumping or adhering, ensuring the uniformity of heating and the long-term stable operation of the equipment.

[0036] Please refer to the details. Figures 1-4 Two gears 7 are fixedly connected to the circumferential surfaces of the two rotating shafts 5 respectively, and a gear ring 8 is fixedly connected inside the heating main body device 1. The gears 7 and the gear ring 8 mesh with each other.

[0037] In this embodiment, two gears 7 are fixedly connected to the circumferential surfaces of the two rotating shafts 5 respectively. This design allows the gears 7 to rotate synchronously with the rotation of the rotating shafts 5. A gear ring 8 is fixedly connected inside the heating main unit 1, forming a precise meshing relationship with the gears 7. When the motor 2 starts and drives the output shaft 3 to rotate, the rotating shaft 5 rotates accordingly through the transmission of the rotating device 4, thereby driving the gears 7 fixed on its circumferential surface to rotate. Since the gears 7 mesh with the gear ring 8, the rotation of the gears 7 will cause the gear ring 8 to rotate or swing accordingly. This linkage mechanism allows the stirring and cleaning device 6 to perform stirring and cleaning while rotating with the rotating shaft 5, and at the same time, through the meshing action of the gears 7 and the gear ring 8, the stirring and cleaning device 6 can also achieve radial movement or swinging, expanding the coverage of stirring and cleaning, ensuring uniform stirring and thorough cleaning of the materials inside the heating main unit 1, avoiding material clumping or adhesion, and improving processing efficiency and product quality.

[0038] Please refer to the details. Figures 1-4 The upper end of the heating main equipment 1 is fixedly connected to a cover 9, the upper end of the cover 9 is fixedly connected to a motor 2, and the inside of the cover 9 is rotatably connected to an output shaft 3.

[0039] In this embodiment, the upper part of the heating main device 1 is fixedly connected to the cover 9. This design is intended to provide closed protection for the device, while providing a stable platform for the installation of the motor 2 and the output shaft 3. The upper part of the cover 9 is firmly fixedly connected to the motor 2, which serves as the power source for the entire stirring and cleaning mechanism, ensuring the normal operation of the device.

[0040] Please refer to the details. Figures 1-4 The main heating device 1 is equipped with a heating tank 10, and a toothed ring 8 is fixedly connected inside the heating tank 10. Two stirring and cleaning devices 6 are provided inside the heating tank 10.

[0041] In this embodiment, each heating tank 10 is equipped with two stirring and cleaning devices 6, which are fixedly connected to the lower ends of the two rotating shafts 5. This symmetrical arrangement not only balances the force exerted by the stirring and cleaning devices 6 within the heating tank 10, ensuring the uniformity of stirring, but also improves the efficiency of stirring and cleaning through the coordinated work of the two stirring and cleaning devices 6, ensuring the heating and stirring quality of asphalt concrete, while reducing the adhesion of materials to the inner wall of the heating tank 10, facilitating subsequent cleaning and maintenance.

[0042] Please refer to the details. Figures 1-4The rear end of the heating main device 1 is fixedly connected to the inlet 11, and the front end of the heating main device 1 is fixedly connected to the outlet 12.

[0043] In this embodiment: the rear end of the heating main equipment 1 is fixedly connected to the inlet 11. This design provides a convenient channel for the addition of asphalt concrete raw materials, ensuring that the materials can smoothly and quickly enter the heating tank 10. The front end of the heating main equipment 1 is fixedly connected to the outlet 12, which serves as the output port of the finished asphalt concrete.

[0044] Please refer to the details. Figures 1-4 The lower end of the main heating device 1 is fixedly connected with multiple support feet 13.

[0045] In this embodiment, multiple support feet 13 are fixedly connected to the lower part of the heating main device 1. This design aims to provide stable support and balance for the device, ensuring the stability and safety of the heating main device 1 during operation.

[0046] Please refer to the details. Figures 1-4 Multiple heat dissipation vents 14 are provided on both sides of the main heating device 1, and a controller 15 is fixedly connected to one side of the main heating device 1.

[0047] In this embodiment, multiple heat dissipation vents 14 are provided on both sides of the main heating device 1. This design aims to achieve effective heat dissipation during the operation of the device, prevent overheating caused by internal heat accumulation, and avoid affecting processing efficiency and equipment life. The controller 15 can automatically adjust the heating power and stirring speed to adapt to different material characteristics and processing requirements, thereby improving heating efficiency and product quality.

[0048] The working principle and usage process of this utility model are as follows: First, the asphalt concrete raw material to be heated is added through the feed inlet 11 at the rear end of the heating main equipment 1. Then, the motor 2 located on the upper end of the cover 9 is started, and the output shaft 3 inside the motor 2 begins to rotate. Through the cooperation of the rotator 4, the power is transmitted to the two rotating shafts 5. As the rotating shafts 5 rotate, the stirring and cleaning device 6 fixed at its lower end begins to stir the material in the heating tank 10. At the same time, the gear 7 on the circumferential surface of the rotating shaft 5 meshes with the toothed ring 8 fixed inside the heating tank 10, so that while the stirring and cleaning device 6 rotates, it can also achieve radial movement or oscillation through the interaction between the gear 7 and the toothed ring 8, expanding the stirring and cleaning range and ensuring that the material is heated evenly. During the heating process, the heat dissipation vents 14 on both sides of the heating main equipment 1... This device helps dissipate heat inside the equipment, keeping the operating temperature within a safe range. Simultaneously, the controller 15 monitors and regulates various parameters of the heating process in real time, ensuring precise control. After processing, the finished asphalt concrete is discharged through the outlet 12 at the front end of the main heating equipment 1. This device solves the problem of traditional asphalt concrete processing heating devices lacking a stirring mechanism to assist in enhancing the heating process, which leads to uneven heating of asphalt and aggregates. However, by adding a stirring mechanism to the heating device, the contact area between the asphalt and aggregates increases when they are stirred, thereby accelerating heat transfer and distribution, making the heating more uniform and efficient. Furthermore, the addition of self-cleaning parts to the drum should be considered to ensure efficient operation of the device and reduce maintenance requirements.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
