Description

Technical Field

[0001] This invention relates to the field of asphalt recycling roller technology, specifically to a mobile asphalt recycling roller anti-clogging material heating device and method. Background Technology

[0002] In the asphalt recycling process, heating the anti-clogging material in the roller is a crucial step in ensuring production efficiency and product quality. Currently, the mainstream method for heating the anti-clogging material in rollers generally employs a fixed-position heating device. The heating component is typically fixedly installed at the roller feed end, attempting to raise the overall temperature of the recycled asphalt by heating the feed area to prevent material sticking and clogging. This fixed heating structure has developed a relatively mature installation and usage model through long-term application and is widely used in various types of asphalt recycling production equipment.

[0003] However, existing fixed-position heating devices have significant technical drawbacks. Because the heating components are fixed in position, the heating position cannot be flexibly adjusted according to the material adhesion and blockage in different areas within the drum. This results in uneven heating of the recycled asphalt, with areas far from the feed end, such as the middle and tail of the drum, prone to localized low temperatures. This leads to recycled asphalt adhering to the inner wall of the drum, causing material adhesion and blockage. To solve this problem, frequent manual cleaning is required during production, which not only consumes significant manpower and time but also interrupts the production process. Furthermore, frequent material adhesion and blockage accelerates wear on equipment components, increases equipment failure frequency, shortens equipment lifespan, further increases maintenance and replacement costs, and seriously affects the continuity and stability of asphalt recycling production. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a mobile asphalt recycling drum anti-clogging heating device to prevent material sticking and blockage, thereby improving heating efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mobile asphalt recycling drum anti-clogging material heating device includes a drum body, a heating component, a moving component, a temperature detection component, and a control component. The drum body serves as a container and conveyor for the recycled asphalt material. The heating component is sleeved on the outside of the drum body for heating the drum body. The moving component is installed below the heating component for driving the heating component to move along the axis of the drum body. The temperature detection component is used to collect the temperature data of the drum body in real time. The control component is electrically connected to the heating component, the moving component, and the temperature detection component for controlling the overall operation of the device.

[0007] Preferably, the moving component includes a base and a linear motion module; the base is laid along the axial direction of the roller body; the linear motion module is mounted on the base; the heating component is mounted on the linear motion module, and the linear motion module drives the heating component to move along the axial direction of the roller body.

[0008] Preferably, the linear motion module includes a guide rail, a slider, a ball screw, and a drive motor; the drive motor and the guide rail are fixed on the base; the ball screw is rotatably mounted on the base and is connected to the output shaft of the drive motor; the slider is slidably mounted on the guide rail and connected to the ball screw; the heating component is mounted on the slider; the drive motor drives the ball screw to rotate, driving the slider and the heating component to slide on the guide rail.

[0009] Preferably, the heating assembly includes a housing and an electric heater; the housing is mounted on the movable assembly; the housing has a channel for the roller body to pass through; the electric heater is fixed to the housing; and the outer wall of the roller body is heated by the electric heater.

[0010] Preferably, the electric heater is an electric heating tube.

[0011] Preferably, the temperature detection component is a thermocouple temperature sensor.

[0012] Preferably, the thermocouple temperature sensor is arranged in the middle and tail of the drum body.

[0013] Preferably, the control component includes a PLC controller; the PLC controller is electrically connected to a touch screen.

[0014] A method for heating anti-clogging material in a mobile asphalt recycling drum includes the following steps:

[0015] S1. Temperature data of the corresponding area inside the drum body is collected in real time by thermocouple temperature sensors installed in the middle and tail of the drum body, and the temperature data is transmitted to the PLC controller of the control component.

[0016] S2. After receiving the temperature data, the PLC controller compares and analyzes it with the preset target heating temperature to determine whether there are areas of material sticking or blocking inside the drum body.

[0017] S3. If there is a material blockage area, the PLC controller calculates the deviation between the current temperature and the target heating temperature according to the PID algorithm. It quickly responds to the deviation through the proportional link, eliminates the steady-state error through the integral link, and suppresses the trend of deviation change through the derivative link, and outputs a control signal to the moving component. After receiving the signal, the drive motor of the moving component drives the ball screw to rotate, and drives the slider and heating component to move along the guide rail to the outer wall of the roller body corresponding to the material blockage area, so as to achieve precise positioning.

[0018] S4. After the heating component moves to the designated position, the PLC controller adjusts the output power of the electric heater of the heating component according to the control signal output by the PID algorithm to perform directional heating on the outer wall of the drum body in the blocked area; until the temperature data collected by the thermocouple temperature sensor reaches the target heating temperature, the PLC controller controls the electric heater to maintain a constant temperature or turn it off.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] Through a mobile heating design, the heating components can move flexibly along the drum axis. Combined with precise temperature detection of key areas of the drum, targeted heating can be applied to areas prone to material sticking and clogging, fundamentally solving the uneven heating problem caused by traditional fixed heating methods and achieving precise anti-sticking and clogging. The directional heating mode concentrates heating power on the clogged area, avoiding the energy waste caused by traditional all-area heating. While improving overall heating efficiency, it effectively reduces energy consumption and energy costs in the production process. Frequent manual cleaning is eliminated, significantly reducing manpower and time investment, and lowering labor costs in the production process. At the same time, it reduces equipment failures caused by material sticking and clogging, reduces equipment wear, extends equipment life, and thus reduces various costs associated with equipment maintenance and replacement. With the help of an adaptive temperature control system, all components work together to ensure that the asphalt recycled material inside the drum remains in a uniform and stable heating state, avoiding production interruptions caused by localized temperature anomalies and ensuring the continuous and stable operation of the asphalt recycling production process.

[0026] The invention will now be further described with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1 , Figure 2As shown, a mobile asphalt recycling drum anti-clogging material heating device includes a drum body 1, a heating component 4, a moving component 2, a temperature detection component 5, and a control component 3. The drum body 1 serves as a carrier for containing and conveying asphalt recycling material, providing a stable containing space and conveying path for the asphalt recycling material, and ensuring the basic operation of the production process. The heating component 4 is sleeved on the outside of the drum body 1 and is used to heat the drum body 1. The moving component 2 is installed at the lower part of the heating component 4 and is used to drive the heating component 4 to move along the axial direction of the drum body 1. The temperature detection component 5 is used to collect the temperature data of the drum body 1 in real time. The control component 3 is electrically connected to the heating component 4, the moving component 2, and the temperature detection component 5 and is used to control the overall operation of the device.

[0029] In this embodiment, the moving component 2 includes a base 22 and a linear motion module; the base 22 is laid along the axial direction of the roller body 1; the linear motion module is installed on the base 22; the heating component 4 is installed on the linear motion module, and the heating component 4 is driven to move along the axial direction of the roller body 1 through the linear motion module, so as to realize the directional movement of the heating component 4 and provide structural support for accurately aligning the sticky and blocked areas.

[0030] In this embodiment, the linear motion module includes a guide rail 23, a slider, a ball screw 21, and a drive motor. The drive motor and the guide rail 23 are fixed on the base 22. The ball screw 21 is rotatably mounted on the base 22 and is connected to the output shaft of the drive motor. The slider is slidably mounted on the guide rail 23 and connected to the ball screw 21. The heating component 4 is mounted on the slider. The drive motor drives the ball screw 21 to rotate, which in turn drives the slider and the heating component 4 to slide on the guide rail 23. The mechanical transmission structure ensures the smoothness of the movement and the positioning accuracy of the heating component 4, meeting the heating needs of different areas.

[0031] In this embodiment, the heating component 4 includes a housing 42 and an electric heater 41; the housing 42 is mounted on the moving component 2; the housing 42 has a channel for the roller body 1 to pass through; the electric heater 41 is fixed on the housing 42; the outer wall of the roller body 1 is heated by the electric heater 41, and the electric heater 41 is made to fit close to the outer wall of the roller by means of a sleeve connection, thereby improving the heat transfer efficiency and realizing directional heating.

[0032] In this embodiment, the electric heater 41 is an electric heating tube, which is a high-efficiency and stable heating element to ensure sufficient heating power, quickly increase the temperature of the blocked area, and avoid material sticking and blockage.

[0033] In this embodiment, the temperature detection component 5 is a thermocouple temperature sensor, which uses a high-precision temperature detection element to accurately collect temperature data inside the drum, providing a reliable basis for subsequent control decisions.

[0034] In this embodiment, thermocouple temperature sensors are installed in the middle and tail of the drum body 1 to monitor the temperature in key areas that are prone to clogging in traditional technologies, ensuring that risks are detected and dealt with early.

[0035] In this embodiment, the control component 3 includes a PLC controller; the PLC controller is electrically connected to a touch screen, and the PLC controller realizes the coordinated control of various components. The touch screen simplifies human-machine interaction and makes it convenient for operators to set parameters and monitor the operating status.

[0036] Working principle:

[0037] This device uses temperature detection component 5 to collect real-time temperature data from the middle and rear of the drum body 1 and transmits it to control component 3. Control component 3 compares and analyzes the collected temperature data with the preset target heating temperature to determine if there are any areas of material adhesion or blockage. When a blockage area is identified, control component 3 sends a drive command to moving component 2. Moving component 2, through a mechanical transmission structure, drives heating component 4 to move along the axis of drum body 1 to the corresponding outer wall position of the blockage area. Subsequently, control component 3 activates heating component 4 to directionally heat the blockage area until the temperature reaches the preset target value. Control component 3 then controls heating component 4 to maintain a constant temperature or turn it off, achieving adaptive temperature control and precise anti-blocking, ensuring continuous and stable operation of asphalt recycling production.

[0038] Example 2

[0039] like Figure 3 As shown, a method for heating anti-clogging material in a mobile asphalt recycling drum includes the following steps:

[0040] S1. By using thermocouple temperature sensors installed in the middle and tail of the drum body 1, the temperature data of the corresponding area inside the drum body 1 is collected in real time, and the temperature data is transmitted to the PLC controller of the control component 3. The temperature information of the middle and tail of the drum is obtained in real time, providing data support for judging the risk of sticking and reducing the error and cost of manual monitoring.

[0041] After receiving the temperature data, the S2 and PLC controllers compare and analyze it with the preset target heating temperature to determine whether there are areas of material sticking or blocking inside the drum body 1. By comparing and analyzing the data, the blocking areas are accurately identified, achieving adaptive judgment, reducing manual intervention, and improving the level of intelligent control.

[0042] S3. If there is a blockage area, the PLC controller calculates the deviation between the current temperature and the target heating temperature according to the PID algorithm. It quickly responds to the deviation through the proportional link, eliminates the steady-state error through the integral link, and suppresses the trend of deviation change through the derivative link, and outputs a control signal to the moving component 2. After receiving the signal, the drive motor of the moving component 2 drives the ball screw 21 to rotate, and drives the slider and heating component 4 to move along the guide rail 23 to the outer wall of the roller body 1 corresponding to the blockage area, so as to achieve precise positioning, avoid blind heating, ensure targeted heating, and reduce energy consumption.

[0043] S4. After the heating component 4 is moved to the designated position, the PLC controller adjusts the output power of the electric heater of the heating component 4 according to the control signal output by the PID algorithm, and performs directional heating on the outer wall of the drum body 1 in the material blockage area; until the temperature data collected by the thermocouple temperature sensor reaches the target heating temperature, the PLC controller controls the electric heater to maintain a constant temperature or turn it off, quickly raising the temperature to the target value, solving the material sticking and blockage problem caused by uneven heating from the root, and maintaining a constant temperature to ensure production stability.

[0044] Through the touchscreen human-machine interface, users can set the target temperature and PID parameters (proportional coefficient P, integral time I, derivative time D), and can also display information such as the current temperature and heating status in real time, which facilitates parameter adjustment and status monitoring and ensures production continuity.
