[0036] According to one aspect of the present application, a coal slag processing system is provided, which is used to realize the transportation of coal slag.

[0037] Specifically, see Figures 1 to 3 , the coal slag treatment system includes:

[0038] At least two unmanned vehicles 1, each of which has a slag inlet hole on its top;

[0039] The main body 2, the slag discharge pipe 3, the slag discharge door 4 and the pressure sensor 5, the interior of the main body 2 is hollow to form a chamber 201; the side wall of the main body 2 is provided with an inlet and outlet for the unmanned vehicle 1 to enter and exit; the top of the chamber 201 is vertically provided with a slag discharge pipe 3, the lower end of the slag discharge pipe 3 is provided with a slag discharge port, and the slag discharge port is connected to the slag discharge door 4; the bottom of the chamber 201 is provided with the pressure sensor 5;

[0040] A motor and a controller 7, wherein the motor is connected to the slag discharge door 4 and is used to control the opening or closing of the slag discharge door 4; the motor and the pressure sensor 5 are respectively connected to the controller;

[0041] When the unmanned vehicle 1 enters the chamber 201, the slag inlet hole corresponds to the slag outlet, and the unmanned vehicle 1 is located above the pressure sensor 5; when the pressure data detected by the pressure sensor 5 is greater than the first threshold, the controller 7 is used to control the motor to open the slag outlet door 4 according to the detection data of the pressure sensor 5, and the coal slag passes through the slag outlet pipe 3 and the slag inlet hole in sequence and enters the interior of the unmanned vehicle 1;

[0042] When the unmanned vehicle 1 is full, the controller 7 is used to control the motor to close the slag discharge door 4, and the unmanned vehicle 1 drives out of the chamber 201; at the same time, another unmanned vehicle 1 drives into the chamber 201; wherein, at least two unmanned vehicles 1 are used to alternately output coal slag.

[0043] In the embodiment of the present application, when the unmanned vehicle 1 drives into the chamber 201, the slag inlet hole corresponds to the slag outlet, and the unmanned vehicle 1 is located above the pressure sensor 5; when the pressure data detected by the pressure sensor 5 is greater than the first threshold value, the controller 7 is used to control the motor to open the slag outlet door 4 according to the detection data of the pressure sensor 5, and the coal slag passes through the slag outlet pipe 3 and the slag inlet hole in turn into the interior of the unmanned vehicle 1, thereby preventing the coal slag from being scattered on the ground and improving the transportation efficiency of the coal slag.

[0044] Furthermore, by using at least two unmanned vehicles 1 to alternately output the coal slag, the coal slag can be transported in a timely manner, effectively avoiding the storage of the coal slag in the coal slag warehouse, and further significantly improving the transportation efficiency of the coal slag.

[0045] In addition, when the unmanned vehicle 1 is full, the controller 7 controls the motor to close the slag discharge door 4, and the unmanned vehicle 1 drives out of the chamber 201. At the same time, another unmanned vehicle 1 drives into the chamber 201, which facilitates the automatic control of the transportation of coal slag and is very simple to operate.

[0046] Exemplarily, the controller 7 uses an STM32H743 single-chip microcomputer, which is directly connected to the DCS system of the thermal power plant through a lora communication module, and displays the data of the pressure sensor 5 and the infrared ranging unit 8 in real time on the DCS system.

[0047] In a specific implementation, the pressure sensor 5 monitors the pressure data in real time, and transmits the pressure data to the STM32H743 single-chip microcomputer through the circuit. The STM32H743 single-chip microcomputer performs real-time calculation and processing on the data. When the pressure data is greater than or equal to the first threshold, the information is wirelessly transmitted from the lora communication module to the controller 7 via the lora communication base station in the factory. The controller 7 calculates the pressure data, and transmits the calculation result to the motor through the circuit. The motor controls the slag discharge door 4 to open according to the signal.

[0048] Alternatively, see Figure 1 and Figure 3 , the coal slag treatment system also includes an infrared distance measuring unit 8, and the infrared distance measuring unit 8 is connected to the controller 7;

[0049] The infrared distance measuring unit 8 is arranged inside the cargo box of the unmanned vehicle 1, and the infrared distance measuring unit 8 is used to measure the accumulation height of the coal slag in the cargo box; wherein, a slag inlet hole is arranged on the cargo box;

[0050] When the accumulation height of the coal slag in the cargo box is greater than a second threshold, the unmanned vehicle 1 is full; at the same time, the controller 7 is used to control the motor to close the slag discharge door 4 according to the detection data of the infrared ranging unit 8.

[0051] In the above embodiment, the stacking height of the coal slag in the cargo box can be accurately measured by the infrared distance measuring unit 8. When the stacking height of the coal slag in the cargo box is greater than the second threshold value (that is, the cargo box is full), the controller 7 controls the motor to close the slag discharge door 4 according to the detection data of the infrared distance measuring unit 8, so that the operation of loading the coal slag by the unmanned vehicle 1 is very simple, and it is easy to realize the automatic control of coal slag loading.

[0052] Exemplarily, the infrared distance measuring unit 8 detects the stacking height of the coal slag in the cargo box in real time, and transmits the height data to the STM32H743 single-chip microcomputer through the circuit. The single-chip microcomputer calculates and processes the data. When the distance data is less than or equal to the second threshold, the information is wirelessly transmitted to the controller 7 by the lora communication module through the lora communication base station in the factory. After receiving the signal, the controller 7 calculates the height data, transmits the calculation result to the motor through the circuit, and the motor controls the slag discharge door 4 to close according to the signal.

[0053] For example, the slag discharge door 4 is rotatably connected to the slag discharge pipe 3 via a rotating shaft, and the rotating shaft is fixed to the output shaft of the motor, that is, the rotation angle of the rotating shaft is controlled by rotating the output shaft of the motor, thereby controlling the opening or closing of the slag discharge door 4, which is simple to operate.

[0054] Optionally, the cross section of the slag discharge pipe 3 is annular, which helps the coal slag to enter the cargo box of the unmanned vehicle 1 through the slag discharge pipe 3 .

[0055] Optionally, the inner diameter of the middle part of the slag discharge pipe 3 is larger than the inner diameter of the end part of the slag discharge pipe 3. This allows part of the coal slag to be stored in the slag discharge pipe 3, thereby better optimizing the volume of the coal slag storage.

[0056] Alternatively, see Figure 1 and Figure 3 The slag treatment system further includes a tracking module 9, which is disposed on the unmanned vehicle 1 and connected to the controller 7. The tracking module 9 helps the unmanned vehicle 1 to travel along a preset route.

[0057] Exemplarily, a black path can be laid on the path along which the unmanned vehicle 1 runs to facilitate identification and recording by the tracking module, or the positioning component can cooperate with the tracking module to facilitate the unmanned vehicle 1 to record multiple routes, thereby facilitating the unmanned vehicle 1 to transport on multiple routes without human operation through the tracking module, thereby saving manpower and improving the convenience and safety of the use of the unmanned vehicle 1.

[0058] Optionally, the tracking module 9 is arranged at the bottom of the unmanned vehicle 1. This facilitates the tracking module 9 to identify the preset route.

[0059] Optionally, the coal slag treatment system further includes an ultrasonic ranging module 10 , which is disposed on the unmanned vehicle 1 , and is connected to the controller 7 .

[0060] In the above embodiment, the ultrasonic ranging module 10 helps to detect the environment around the unmanned vehicle 1 and ensure the safety of the unmanned vehicle 1 during its movement.

[0061] Optionally, the front side, the rear side, the left side, and the right side of the unmanned vehicle 1 are all provided with the ultrasonic ranging module 10. This helps to better ensure the safety of the unmanned vehicle 1 during its travel.

[0062] Optionally, the coal slag processing system further includes a braking component and a driving component, the braking component and the driving component are both arranged on the unmanned vehicle 1, and the braking component is connected to the controller 7;

[0063] The braking component is connected to the driving component to brake the driving component, and the driving component is used to drive the unmanned vehicle 1 to move.

[0064] In the above embodiment, the controller 7 can better control the braking components, thereby realizing the driving of the driving components, better ensuring that the unmanned vehicle 1 moves along the preset route under the action of the controller 7, and improving the automation of the coal slag transfer operation.

[0065] Optionally, there are two unmanned vehicles 1. This can improve the efficiency of coal slag transportation and save costs.

[0066] In a specific embodiment, the pressure sensor 5 is arranged below the slag discharge pipe 3. The unmanned vehicle 1 is parked above the pressure sensor 5 according to the path. When an unmanned vehicle 1 is in position below the slag discharge port (above the pressure sensor 5), the slag discharge door 4 is opened, and the coal slag freely falls from the slag discharge door 4 of the slag discharge pipe 3 into the cargo box. There is an infrared ranging unit 8 in the cargo box. When the infrared ranging unit 8 detects that the coal slag is full, the slag discharge door 4 is closed, and the unmanned vehicle 1 drives away from the bottom of the slag discharge port, and the next unloaded unmanned vehicle 1 is replaced to load the coal slag, and the cycle is carried out in this way. The degree of automation is high, and the transportation efficiency of the coal slag is high.

[0067] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
