[0025] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0026] It should be noted that, in the following embodiments, the “first” and “second” mentioned do not represent an absolute distinction in structure and / or function, nor do they represent a sequential order of execution, but are merely for the convenience of description.

[0027] The present invention provides an energy-saving control system for a single dust collector in a belt transfer station, comprising a material signal collector and a controller electrically connected to the material signal collector, wherein the material signal collector is installed at a first position and a second position of a belt conveyor, and the controller is configured to calculate the material transportation time of the belt conveyor after the material signal collector at the first position detects the material, control the motor speed of the single dust collector to increase after the material reaches the single dust collector, and control the motor speed of the single dust collector to decrease after the material signal collector at the second position fails to detect the material.

[0028] Specifically, the first position is located at the head of the belt conveyor, and the second position is located at the tail of the belt conveyor. The material is transported from the head to the tail of the belt conveyor. A material signal collector is set at a suitable position of the belt conveyor. When the single dust collector controller receives the material head signal, the single dust collector motor speed is fully opened; when the single dust collector controller receives the material tail signal, the single dust collector motor speed is reduced to a suitable speed.

[0029] like Figure 2 As shown, the material signal collector includes a contact plate and a contact sensor electrically connected to the controller. The contact plate is rotatable and configured to trigger the contact sensor. The contact plate is used to contact the material on the conveying belt of the belt conveyor. When the contact plate contacts the conveyed material, the contact plate rotates, triggering the contact sensor, and the contact sensor sends a signal to the controller.

[0030] like Figure 2 As shown, the material signal collector also includes a bracket, the contact plate is rotatably connected to the bracket through a hinge, the contact sensor is fixedly arranged on the bracket, and the bracket is fixedly arranged. The upper end of the contact plate is rotatably connected to the bracket through a hinge, and the lower end of the contact plate is located above the conveyor belt.

[0031] like Figure 2 As shown, the material signal collector also includes a reset spring, which is connected to the contact plate and is configured to control the contact plate to reset. The reset spring applies an elastic force to the contact plate so that the contact plate can be reset in time. When the material contacts the contact plate, the contact sensor is triggered to send a material running signal to the controller; when the material conveying is finished, the spring pulls the contact plate back to its original position, the contact sensor loses the signal, and the first control controller issues an instruction to end the material conveying.

[0032] A material signal collector is provided at the first position. After the material signal collector at the first position detects the material, it sends a signal to the controller, and the controller calculates the first material transportation time t1 of the belt conveyor, t1=L1 / n, wherein L1 is the distance between the material signal collector at the first position and the monomer dust collector, and n is the belt speed of the belt conveyor.

[0033] The first material transportation time is used as the time to determine when the dust collector starts to accelerate. After the running time of the belt conveyor reaches the first material transportation time, the material transported by the belt conveyor reaches the single dust collector, and the controller sends a signal to the single dust collector to control the motor speed of the single dust collector to increase, and the dust removal power of the single dust collector increases to meet the dust collection requirements.

[0034] A material signal collector is provided at the second position. When material transportation is finished, the material signal collector at the second position does not detect the material, and the contact plate does not trigger the contact sensor. The controller calculates the second material transportation time t2 of the belt conveyor, t2=L2 / n, wherein L2 is the distance between the material signal collector at the second position and the monomer dust collector, and n is the belt speed of the belt conveyor.

[0035] The second material transportation time is used as the time to determine when the dust collector starts to decelerate. From the moment when the material signal collector at the second position does not detect the material, after the running time of the belt conveyor meets the second material transportation time, it is determined that the material has left the single dust collector, and then the controller sends a signal to the single dust collector to control the motor speed of the single dust collector to reduce, and the dust removal power of the single dust collector is reduced to achieve the purpose of saving electricity. At the end of material transportation, the belt conveyor is still controlled to operate. The second material transportation time takes into account a certain margin and delay, and takes into account the control of the dust margin during the material transportation process to ensure effective dust removal. During the first material transportation time and the second material transportation time, the single dust collector is in the state of maximum dust removal power and the motor is in the state of highest speed.

[0036] The above-mentioned belt transfer station single dust collector energy-saving control system has the following advantages:

[0037] 1. Energy saving

[0038] Intelligent control of motor speed: The system dynamically adjusts the motor speed according to whether the material has reached the position of the single dust collector through the cooperation of the material signal collector and the controller. When the material head is detected, the motor speed is increased; when the material tail is detected, the motor speed is reduced. This on-demand adjustment mode avoids the dust collector motor from running at high load for a long time and saves energy consumption.

[0039] Reduce idling energy consumption: The dust collector increases the motor speed only when it needs to run efficiently (materials arrive), and keeps running at a low speed when no materials pass through, effectively reducing idling energy consumption.

[0040] 2. Improve dust removal efficiency

[0041] Accurate response to material arrival: The material signal collector can detect the arrival of materials in real time, ensuring that the single dust collector runs at full speed during material transportation, improving dust removal efficiency, and avoiding dust leakage caused by delayed response of the dust collector.

[0042] Dynamically adapt to conveying status: The system can adapt to the dust removal needs under different conveying conditions, avoiding excessive or insufficient dust removal problems caused by fixed speed design, thereby achieving efficient dust removal.

[0043] 3. Reduce operating costs

[0044] Reduced equipment wear: By reducing unnecessary high-speed operation time, the wear of the motor and related components is reduced, the service life of the equipment is extended, and the maintenance and replacement costs are reduced.

[0045] Elastic recovery structure reduces failure rate: The contact plate is automatically reset by the reset spring, which reduces the risk of mechanical jamming of the signal collector and improves the stability of equipment operation.

[0046] 4. Flexible and reliable material detection mechanism

[0047] ·Contact sensor has high accuracy: the contact plate is in direct contact with the material, the trigger signal is highly accurate, and it can quickly respond to the movement state of the material to avoid missed detection and false detection.

[0048] Self-reset function enhances sensitivity: The reset spring enables the contact plate to quickly return to its initial position after detection, ensuring that the signal collector can continuously detect the passing status of multiple material batches.

[0049] Strong resistance to environmental interference: Compared with non-contact sensors (such as photoelectric or ultrasonic), contact sensors are not easily affected by ambient light, dust or humidity, and are suitable for harsh industrial environments.

[0050] 5. Reasonable structural design

[0051] Stability of the contact plate and bracket: The contact plate is connected to the bracket through a hinge, and the bracket is fixed. The overall structure is stable and durable, and can adapt to long-term operation and frequent material detection work.

[0052] ·Easy to install and maintain: The combined structure of the contact plate, bracket and return spring is simple, easy to install, debug and maintain, and reliable operation can be ensured without complicated operations.

[0053] Non-intrusive material detection: The contact plate only contacts the material without causing any interference to the conveyor belt, which will not affect the material conveying and the normal operation of the belt.

[0054] 6. Improved environmental performance

[0055] Reduce dust pollution: By dynamically adjusting the dust collector speed, dust in the transportation process is captured in time, reducing dust emissions in the transfer station and surrounding environment, and improving environmental protection performance.

[0056] Reduce noise pollution: The dust collector motor keeps running at a low speed when there is no material passing through, which helps to reduce operating noise and provide better comfort for the working environment.

[0057] 7. High degree of intelligence

[0058] Convenient automatic control: The controller can automatically judge and respond to material signals without manual intervention, which improves the intelligence level and operation efficiency of the system.

[0059] Support parameter adjustment and optimization: The system can adjust controller parameters according to the characteristics of different materials, such as signal delay, speed adjustment range, etc., to further optimize system performance.

[0060] 8. Precise timing

[0061] Material transportation time calculation: Through clear mathematical formulas, the time it takes for materials to arrive at or leave the single dust collector from the detection point is accurately calculated to ensure that the dust collector operates at the best state during the material passing.

[0062] Dynamically adjust dust removal power: Based on the real-time material position, control the acceleration and deceleration of the single dust collector motor, avoid the problem of early or delayed start, and improve the accuracy of system response.

[0063] · Operate the dust collector on demand: The highest dust removal power is turned on only when the material passes through the single dust collector, avoiding the waste of long-term high-load operation of the dust collector, thereby effectively reducing energy consumption.

[0064] Consider the dust margin: set the second material transportation time, fully consider the dust problem at the end of material transportation, even if the material transportation is finished, the belt conveyor and dust collector will continue to run for a period of time to ensure complete dust collection. This design achieves a balance between energy saving and dust removal effect.

[0065] The present invention also provides an energy-saving control method for a single dust collector of a belt transfer station, which adopts the energy-saving control system for the single dust collector of the belt transfer station and comprises the following steps:

[0066] S1, belt conveyor starts to transport materials;

[0067] S2, after the material signal collector at the first position detects the material, it sends a signal to the controller, and the controller calculates the first material transportation time of the belt conveyor;

[0068] S3, after the material reaches the single dust collector, the controller sends a signal to the single dust collector to control the motor speed of the single dust collector to increase;

[0069] S4, when the material transportation is finished, the material signal collector at the second position does not detect the material, and the controller calculates the second material transportation time of the belt conveyor;

[0070] S5. After the material leaves the single dust collector, the controller sends a signal to the single dust collector to control the motor speed of the single dust collector to decrease.

[0071] In the above step S2, the material signal collector at the second position sends a signal to the controller after detecting the material.

[0072] In the above step S2, the first material transportation time t1=L1 / n, wherein L1 is the distance between the material signal collector at the first position and the monomer dust collector, and n is the belt speed of the belt conveyor.

[0073] In the above step S4, the second material transportation time t2=L2 / n, wherein L2 is the distance between the material signal collector at the second position and the monomer dust collector, and n is the belt speed of the belt conveyor.

[0074] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
