[0030] Conveyor belts are used throughout material handling systems in a variety of industries, including mining, metallurgy, coal, ports, and the chemical industry. Cleaners are installed at the head and tail of the conveyor belts to remove residual material from the working surface, ensuring safe operation of the entire production line. Winter temperatures in northern ports often drop below 0°C. After the conveyor belts transport materials to their destinations, the material adhering to the conveyor belt surface is susceptible to freezing due to the low temperatures, shortening the service life of the conveyor belts and cleaners. This technical issue presents a problem in the field, as cleaners have limited adaptability.

[0031] Hereinafter, the technical solution of the present application will be described in conjunction with specific embodiments.

[0032] Example 1

[0033] Figure 1 This is a schematic diagram of the structure of a heating conveyor belt cleaner provided in an embodiment of the present application. Figure 1 As shown, in the technical solution of this embodiment, a conveyor belt cleaner is provided, including: a coal scraper, a heater and a heating shield; the heater is installed at the end of the coal scraper away from the conveyor belt, and is in contact with the surface of the coal scraper; the heating shield is installed on the surface of the coal scraper, and is in contact with the surface of the coal scraper.

[0034] The technical problem to be solved by this embodiment is that in the low temperature environment of winter, the materials adhered to the surface of the conveyor belt of the traditional conveyor belt cleaner are easily frozen, resulting in a decrease in the cleaning effect of the cleaner and an increase in the wear of the conveyor belt and the cleaner, which reduces the service life.

[0035] The technical solution of this embodiment installs a heater on the end of the scraper away from the conveyor belt, and a heating shield is attached to the scraper surface to provide heat to the scraper, preventing material from freezing on the scraper. For example, in a northern port, where winter temperatures often drop below 0°C, traditional cleaners are significantly less effective at cleaning material stuck to the conveyor belt due to freezing.

[0036] After adopting the conveyor belt cleaner of this embodiment, the heater and the heating shield can continuously heat the scraper, so that the temperature of the scraper is maintained above the preset temperature, such as above 0°C, effectively preventing the material from freezing on the scraper. In this way, the cleaner can always maintain a good cleaning effect, and the center position of the cleaner will not change due to freezing of the material, thereby making the fit between the cleaner and the conveyor belt tighter and improving the cleaning efficiency. At the same time, due to the improvement in the cleaning effect, there is no need to increase the torque of the cleaner as in traditional treatment methods, thereby reducing the interaction force between the conveyor belt and the cleaner and extending the service life of the conveyor belt and the cleaner. In addition, the use of self-cleaning heated conveyor belt cleaners has greatly improved the operating efficiency of the equipment, so that even in the cold winter, material transportation systems such as ports can still maintain environmentally friendly and efficient operation.

[0037] Example 2

[0038] Figure 2 This is a schematic diagram of the structure of a self-cleaning conveyor belt cleaner provided in an embodiment of the present application. Figure 2 As shown, based on the above embodiment, the conveyor belt cleaner also includes: a slide rail, a coal scraper and a motor; the slide rail is installed on the end of the coal scraper away from the conveyor belt; the coal scraper slides on the slide rail to clean the cleaner; the motor is connected to the coal scraper and is used to drive the coal scraper to slide on the slide rail.

[0039] The technical problem to be solved by this embodiment is to further improve the self-cleaning ability of the sweeper on the basis of solving the problems of reduced cleaning effect and equipment wear of the sweeper in winter, so as to cope with the problem of accumulation of attachments on the sweeper.

[0040] The technical solution of this embodiment is to install a slide rail at the end of the coal scraper away from the conveyor belt, set a coal scraper that can slide on the slide rail, and drive the coal scraper to slide on the slide rail through a motor to clean the cleaner.

[0041] In winter, material on the conveyor belt surface easily freezes and adheres to the cleaner. Over time, the accumulation of material can significantly impact cleaning effectiveness. In the technical solution of this embodiment, a coal scraper, driven by a motor, slides along a rail to promptly remove material from the cleaner. As the automatic coal scraper moves along the rail, it removes any material adhering to the cleaner. It stops when it reaches the end guard of the rail, completing its cleaning operation and awaiting controller instructions for the next cleaning. This effectively prevents material buildup and keeps the cleaner clean, thereby improving cleaning effectiveness. Furthermore, timely removal of material adhering to the cleaner reduces wear on the cleaner and conveyor belt, extending the life of the equipment. Furthermore, the implementation of the self-cleaning function reduces the workload of cleaning personnel and improves production efficiency. In actual application, the controller controls the time interval and frequency of the automatic coal scraper's reciprocating motion based on the amount of material adhering to the cleaner, enabling the automatic cleaning function of the cleaner and meeting environmental requirements for conveyor belt material handling.

[0042] Example 3

[0043] Figure 3 This is a flow chart of a control method for a conveyor belt cleaner provided in an embodiment of the present application, such as Figure 3 As shown, in the technical solution of this embodiment, a control method for a conveyor belt cleaner based on the above embodiment is provided, the method comprising: judging whether the duration for which the ambient temperature is lower than the preset temperature is greater than or equal to the preset duration; when the duration for which the ambient temperature is lower than the preset temperature is greater than or equal to the preset duration, starting the heater to heat the coal scraper.

[0044] The technical problem to be solved by this embodiment is how to automatically start the heating function of the sweeper according to the ambient temperature to ensure that the sweeper can work normally in a low temperature environment.

[0045] The technical solution of this embodiment is to start the heater to heat the coal scraper when the ambient temperature is lower than the preset temperature for a period of time greater than or equal to the preset time. In actual industrial production, the ambient temperature varies greatly in winter. When the ambient temperature drops to a certain level and lasts for a period of time, the control method of this embodiment can automatically start the heater to heat the coal scraper. For example, the preset temperature is 0°C. When the ambient temperature is lower than 0°C and lasts for a preset time, the heater is started to maintain the temperature of the coal scraper above 0°C to prevent the material from freezing on the coal scraper. This ensures that the sweeper can maintain a good cleaning effect at different ambient temperatures, thereby improving the adaptability and stability of the equipment. At the same time, the automatic control of the heating function can avoid unnecessary energy waste and reduce production costs.

[0046] Example 4

[0047] Based on the above embodiment, the method also includes: the motor includes a first motor arranged at the first end of the slide rail, and a second motor arranged at the second end of the slide rail; when the scraper plate torque is greater than or equal to the torque threshold, the first motor and the second motor are started to drive the scraper plate to slide left and right on the slide rail, and the output power of the heater is increased; when the scraper plate torque is less than the torque threshold, the first motor or the second motor is started to drive the scraper plate to slide left and right on the slide rail.

[0048] The technical problem to be solved in this embodiment is how to adjust the working states of the motor and the heater according to the torque of the coal scraper to achieve efficient cleaning and energy-saving operation.

[0049] The technical solution of this embodiment is to start the first motor (for example, the left motor) and the second motor (for example, the right motor) to drive the coal scraper to slide left and right on the slide rail when the scraper plate torque is greater than or equal to the torque threshold, and to increase the output power of the heater; when the scraper plate torque is less than the torque threshold, start the first motor or the second motor to drive the coal scraper to slide left and right on the slide rail.

[0050] When the scraper is heavily loaded with debris and the scraper torque reaches or exceeds the torque threshold, it indicates significant cleaning resistance. At this point, the first and second motors are activated to work together, increasing the scraper's power and boosting the heater's output, improving cleaning efficiency. When the scraper torque falls below the torque threshold, cleaning resistance is minimal, and a single motor can meet cleaning requirements, saving energy. For example, during winter coal transportation, as coal easily freezes and adheres to the scraper, debris accumulates over time. When the scraper initially operates, the torque is low, and a single motor can complete the cleaning task. Over time, as debris accumulates, the scraper torque increases. When the torque threshold is reached, both motors operate simultaneously, and the heater's power is increased to ensure effective cleaning. This dynamic adjustment improves cleaning efficiency, achieves energy-saving operation, and reduces production costs.

[0051] Example 5

[0052] Based on the above embodiment, before starting the coal scraper, the method also includes: judging whether the current time is within the preset time period and whether the belt conveyor is running; if the current time is within the preset time period and the belt conveyor is running, starting the coal scraper.

[0053] The technical problem to be solved in this embodiment is how to reasonably control the activation time of the coal scraper to ensure efficient cleaning without affecting production. The technical solution of this embodiment is to determine whether the current time is within a preset time period and whether the belt conveyor is running before activating the coal scraper; if the current time is within the preset time period and the belt conveyor is running, the coal scraper is activated.

[0054] In order to improve production efficiency and save energy, it is necessary to reasonably control the start-up time of the coal scraper. In the technical solution of this embodiment, whether to start the coal scraper is determined by judging whether the current time is within the preset time period and whether the belt conveyor is running. For example, the preset time period is the time outside the production peak period. Only when the current time is within this preset time period and the belt conveyor is running, the coal scraper is started for cleaning. This can avoid starting the coal scraper during maintenance and improve production safety. At the same time, starting the coal scraper when the belt conveyor is running can ensure that the cleaning work is carried out synchronously with the material transportation, thereby improving the cleaning effect. In addition, reasonable control of the start-up time of the coal scraper can also reduce unnecessary operation of the equipment, reduce energy consumption, and extend the service life of the equipment.

[0055] Example 6

[0056] Based on the above embodiment, when the first motor fails, the output power of the heater is increased, and the second motor is started to drag the coal scraper for uninterrupted sliding; when the second motor fails, the output power of the heater is increased, and the first motor is started to drag the coal scraper for uninterrupted sliding.

[0057] The technical problem to be solved by this embodiment is how to ensure that the coal scraper operates uninterruptedly to ensure the cleaning effect when the motor fails.

[0058] The technical solution of this embodiment is to increase the output power of the heater when the first motor fails, and start the second motor to drag the coal scraper to slide continuously; when the second motor fails, increase the output power of the heater, and start the first motor to drag the coal scraper to slide continuously. Motor failure is a common problem. If the motor fails and the coal scraper stops running, it will seriously affect the cleaning effect. In the technical solution of this embodiment, when the first motor fails, the output power of the heater is increased to enhance the cleaning effect, and at the same time, the second motor is started to drag the coal scraper to slide continuously to ensure the continuous cleaning work. Similarly, when the second motor fails, corresponding measures are also taken. This can minimize the impact of motor failure on the cleaning effect and ensure the normal production. In addition, by switching the motor and increasing the power of the heater in a timely manner, the reliability and stability of the equipment can be improved, and the maintenance cost and the risk of production interruption can be reduced.

[0060] Figure 4 Schematic diagram of the structure of a control device for a conveyor belt cleaner provided in an embodiment of the present application. Figure 4 As shown, in the technical solution of this embodiment, a control device for a conveyor belt cleaner based on the above embodiment is provided, and the device includes: a judgment module for judging whether the duration for which the ambient temperature is lower than the preset temperature is greater than or equal to the preset duration; and a control module for starting the heater to heat the coal scraper when the duration for which the ambient temperature is lower than the preset temperature is greater than or equal to the preset duration.

[0061] The technical problem to be solved by this embodiment is how to automatically start the heating function of the sweeper according to the ambient temperature to ensure that the sweeper can work normally in a low temperature environment.

[0062] The technical solution of this embodiment is to start the heater to heat the coal scraper when the ambient temperature is lower than the preset temperature for a period of time greater than or equal to the preset time. In actual industrial production, the ambient temperature varies greatly in winter. When the ambient temperature drops to a certain level and lasts for a period of time, the control method of this embodiment can automatically start the heater to heat the coal scraper. For example, the preset temperature is 0°C. When the ambient temperature is lower than 0°C and lasts for a preset time, the heater is started to maintain the temperature of the coal scraper above 0°C to prevent the material from freezing on the coal scraper. This ensures that the sweeper can maintain a good cleaning effect at different ambient temperatures, thereby improving the adaptability and stability of the equipment. At the same time, the automatic control of the heating function can avoid unnecessary energy waste and reduce production costs.

[0071] Embodiment 9

[0072] Based on the above embodiment, this embodiment provides an application example.

[0073] The invention relates to a self-cleaning heated conveyor belt cleaner and a control method, which is mainly used in cleaning conveyor belts in bulk cargo ports and belongs to the field of cleaning technology and environmental protection industry.

[0074] Conveyor belts play a crucial role in modern industrial production, operating throughout material handling systems in industries such as mining, metallurgy, coal mining, ports, and the chemical industry. Because materials can adhere and accumulate during conveyance, cleaners are installed at the head and tail of conveyor belts to maintain their cleanliness. These cleaners are used to remove residual material from the working surface and ensure safe operation of the entire production line. Based on their operating principle, these cleaners can be categorized into three types: traditional, electromagnetic, and spring-loaded. The first is the traditional cleaner: the conveyor belt cleaner contacts the conveyor belt and uses cleaning elements such as scrapers or brushes to remove debris attached to the surface of the conveyor belt and collect it into a designated collection device; the second is the electromagnetic cleaner: it uses the electromagnetic principle to generate a strong magnetic field through the electromagnetic coil. When the conveyor belt is adsorbed on the magnet under the action of magnetic force, the solenoid valve opens to unload the load of the conveyor belt, thereby achieving cleaning; the third is the spring-type cleaner: the spring-type cleaner uses the reset and buffering functions of the spring to enable the cleaner to stick close to the conveyor belt and automatically and quickly change the gap with the conveyor belt, thereby improving the cleaning effect.

[0075] With the strengthening of national environmental protection regulations, port enterprises must implement environmental dust suppression measures during material transportation. A key step is to add water to the material being transported on the conveyor belt to increase its moisture content, thereby preventing dust from forming during transportation and meeting national environmental standards. However, winter temperatures in northern ports often fall below 0°C. After the conveyor belt transfers material to its destination, the material adhering to the conveyor belt surface is susceptible to freezing due to the low temperatures. This leads to two technical issues when the cleaner removes the adhering material: First, the cleaning efficiency of the cleaner decreases. As the amount of material frozen on the cleaner increases, the center position of the cleaner shifts, resulting in a loose fit between the cleaner and the conveyor belt, weakening the cleaner blade's ability to remove adhered material and reducing cleaning efficiency. Second, it increases wear on the conveyor belt and cleaner, shortening their service life. When the cleaner's cleaning efficiency decreases, the traditional approach is to increase the torque of the cleaner to achieve a tighter fit between the cleaner and the conveyor belt. However, this increases the interaction force between the cleaner and the conveyor belt, shortening the service life of both the conveyor belt and the cleaner. In addition, cleaning the frozen attachments on the sweeper in low temperature weather is time-consuming and labor-intensive, affecting the normal operation of production, and operational errors can easily cause damage to the conveyor belt.

[0076] In the face of these problems, port enterprises need to take more effective countermeasures. This application designs a new self-cleaning conveyor belt cleaner with heating to address these technical issues. A heating system is added to the traditional cleaner to maintain the temperature of the belt and cleaner surface, preventing the formation of frozen coal. A self-cleaning device is also added to promptly clean the cleaner of debris, improving the cleaner's effectiveness in winter and reducing the labor intensity of cleaners.

[0077] (1) Implementation of the sweeper heating function

[0078] The sweeper heating components include: a sweeper coal scraper 101, a self-limiting temperature flame-retardant heater 106, a heater shield 102, fixing bolts, a power supply and a power cord.

[0079] The self-regulating flame-retardant heaters 106 are evenly arranged along the back of the scraper blade. The stainless steel heater shield 102 and the self-regulating flame-retardant heater plates 106 are bolted to the surface of the scraper. When powered on, the heat from the heaters 106 is evenly and continuously transferred through the stainless steel heater shield 102 to the outer surface of the shield 102, heating the material adhering to the scraper and maintaining the temperature of the scraper above a preset temperature, such as 0°C, to prevent the material from freezing on the scraper.

[0080] 101- coal scraper of sweeper, 102- heater shield, 103- automatic coal scraper, 104- slide rail end guard, 105- upper and lower slide rails, 106- self-limiting temperature flame retardant heater.

[0081] The self-cleaning components of the sweeper include: a first motor 1071, a second motor 1072, a steel wire 108, upper and lower sliding rails 105, an automatic coal scraper 109, a left end guard plate 1041 of the sliding rail, a right end guard plate 1042 of the sliding rail, a sweeper 100, a heater shield 102, a self-limiting temperature flame-retardant heater 106, mounting screw holes 110, a controller, etc.

[0082] The automatic coal scraper 103 is mounted on upper and lower guide rails 105. A first motor 1071 and a second motor 1072 drive a steel wire rope 108, allowing the automatic coal scraper 109 to move left and right on the heater shield 102. As the automatic coal scraper 109 moves along the rail, it removes material adhering to the cleaner 100. It stops when it reaches the end guard plate 1041 or 1042 of the guide rail, completing the cleaning process and awaiting the controller's instruction to proceed with the next cleaning operation. The controller controls the interval and frequency of the automatic scraper 109's reciprocating motion based on the amount of material adhering to the cleaner 100, enabling the automatic cleaning function and meeting the environmental requirements of conveyor belt material handling.

[0084] About heating system logic. Figure 5This is a schematic diagram of a heater control process provided by an embodiment of the present application. After the process starts, it is first determined whether the heating plate control is started. If started, then it is determined whether the ambient temperature is less than, for example, 0°C. If the ambient temperature is not less than 0°C, the process temporarily does not perform the heating plate start-up operation. If the ambient temperature is less than 0°C, it is further determined whether the duration of the temperature below 0°C meets the preset time length. If the preset time length is met, the heating plate is started; if the preset time length is not met, the heating plate is not started, and the ambient temperature and duration continue to be monitored. When the heating plate is started, the corresponding heating operation is performed until the stop condition is met or other intervening factors appear, and the heating plate stops, at which time the heating plate control ends.

[0085] About the startup logic of the coal scraper system. Figure 6 This is a schematic diagram of the coal scraper system startup process provided by an embodiment of the present application. First, the scraper is activated, followed by the dual motors, and then the scraper torque is tested. If the scraper torque is greater than or equal to a threshold, both motors continue to operate, and the heating plate increases the heating temperature. If the scraper torque is less than the threshold, only one motor operates, and the heating plate maintains a constant temperature. Figure 7 This is another schematic diagram of the coal scraper system startup process disclosed in an embodiment of the present invention. Alternatively, the coal scraper can be started first, and then a determination is made as to whether the scraper has been running for a specified time. If the specified time has not been met, or if the time has been met but the conveyor is not running, the coal scraper is stopped. Otherwise, the coal scraper is started, and the operating frequency and speed of the coal scraper are adjusted based on the temperature.

[0086] About motor switching control logic. Figure 8 This is a schematic diagram of a motor switching process provided in an embodiment of the present application. For each operating motor, a determination is made as to whether the motor is faulty. If the motor is fault-free, normal operation occurs. If a motor fault occurs, a motor alarm sounds, the system stops operation, and maintenance personnel are notified to perform on-site repairs. In the event of a motor failure, the system automatically switches to single-motor operation and disengages dual-motor mode, while the scraper system continues to operate to ensure effective cleaning.

[0087] The use of self-cleaning heated conveyor belt cleaners not only successfully overcomes the reduced cleaning effectiveness caused by low temperatures in winter but also significantly reduces the challenges associated with clean production. This technology effectively reduces friction between the cleaner and the belt surface, extending the life of the conveyor belt. Furthermore, the cleaners ensure that coal cleaners can more efficiently and conveniently clear frozen coal accumulations.

[0088] Furthermore, the use of self-cleaning heated conveyor belt cleaners has significantly improved equipment efficiency, enabling material handling systems in ports and other locations to maintain environmentally friendly and efficient operation even during the cold winter months. The cleaner's heating function prevents material from freezing, eliminating potential safety hazards. Through these comprehensive measures, self-cleaning heated conveyor belt cleaners not only improve operating safety but also meet the demands for greener and more efficient industrial production.
