Technical Field

[0001] This utility model relates to the field of slag discharge technology in power plant slag bins, and more specifically to a slag bin slag discharge control system. Background Technology

[0002] In traditional power plant slag silo discharge processes, at least two workers are required: a driver and an on-site slag discharge operator. During the discharge process, the operator needs to operate the system in real time from the electrical control box. If communication between the driver and the operator is not timely, the vehicle may overflow with slag. Utility Model Content

[0003] This utility model provides a slag discharge control system that reduces labor costs and prevents slag overflow from vehicles, which can at least solve one of the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A slag silo discharge control system includes a slag silo, a slag discharge area, a slag discharge pneumatic door, a vehicle positioning photoelectric switch, a mercury level switch, and a control box; The slag silo stores slag material and is located above the slag discharge area. The slag discharge pneumatic door is installed at the discharge port of the slag silo and is used to open and close to control the discharge of slag material. The slag loading truck drives into the slag discharge area to load slag. The slag discharge area is sequentially set with a front position area, a middle position area, and a rear position area. There are multiple vehicle positioning photoelectric switches, which are respectively installed in each position area to detect whether the slag loading truck has arrived. There are at least two mercury level switches, which are dispersed and hoisted in the slag discharge area at different heights to detect the slag loading level of the slag loading truck at fixed points. The control box establishes communication connections with the vehicle positioning photoelectric switch and the mercury level switch respectively. The control box has a built-in wireless remote control module, which establishes a communication link between the slag discharge pneumatic door and the central control panel of the slag loading truck cab.

[0005] Furthermore, it also includes a bin wall vibrator, at least one of which is installed on the bin wall of the slag bin and establishes a communication connection with the wireless remote control module to vibrate the bin wall of the slag bin to facilitate smooth material discharge.

[0018] See Figures 1-2 This utility model provides a slag bin discharge control system, including a slag bin, a discharge area, a bin wall vibrator 1, a loudspeaker 2, a discharge pneumatic door 3, a vehicle positioning photoelectric switch 4, a mercury level switch 5, and a control box 7. The slag silo stores slag material and is located above the slag discharge area. At least one silo wall vibrator 1 is installed on the silo wall of the slag silo to vibrate the silo wall and facilitate smooth material discharge. The slag discharge pneumatic door 3 is installed at the discharge port of the slag silo and is used to open and close to control the discharge of slag material. A slag truck drives into the slag discharge area to load slag. The slag discharge area is sequentially set with a front position area, a middle position area, and a rear position area. The front position area, the middle position area, and the rear position area are distributed sequentially along the driving-exit direction. There are multiple vehicle positioning photoelectric switches 4, which are installed in each position area to detect whether the slag truck has arrived. There are at least two mercury level switches 5, which are dispersed and hoisted in the slag discharge area at different heights to detect the slag level of the slag truck at fixed points. The control box 7 establishes communication connections with the vehicle positioning photoelectric switch 4 and the mercury level switch 5 respectively. The control box 7 has a built-in wireless remote control module, which establishes communication connections between the bin wall vibrator 1 and the slag discharge pneumatic door 3 and the central control panel of the slag loading truck cab. The control box 7 also has a built-in voice playback board, and the loudspeaker 2 is connected to the voice playback board for outputting audio.

[0019] The specific operating principle of this slag silo discharge control system is as follows: The driver drives the slag-loading truck into the slag discharge area and stops at the front position zone. At this time, the mercury level switch 5, which is hoisted at a lower height, falls into the slag-loading truck's compartment. After the vehicle positioning photoelectric switch 4 detects that the slag-loading truck has arrived, it sends a feedback signal back to the control box 7, triggering the voice playback board to output an alarm prompt and broadcasting "Vehicle in front position zone has arrived" via the loudspeaker 2. After hearing the prompt, the driver uses the central control panel in the cab to remotely open the slag discharge pneumatic door 3 to unload the slag. During the unloading process, when the mercury level switch 5 detects that the slag loaded in the compartment has reached the designated level, it sends a feedback signal back to the control box 7, triggering the voice playback board to output an alarm prompt and broadcasting "Front position zone is full, please move the truck" via the loudspeaker 2. After hearing the prompt, the driver uses the central control panel in the cab to remotely close the slag discharge pneumatic door 3 to stop unloading the slag. At the same time, the driver slowly drives the slag-loading truck to the next area, namely the middle position zone. The detection signal of the vehicle positioning photoelectric switch 4 in the front position zone disappears.

[0020] When the driver drives the slag-loading truck to the middle position zone and stops, the vehicle positioning photoelectric switch 4, located in the middle position zone, detects the truck's arrival and sends a feedback signal back to the control box 7, triggering the voice playback board to output an alarm prompt and broadcasting "Vehicle in middle position zone is in place" via the loudspeaker 2. At this time, the mercury level switch 5 remains inside the slag-loading truck's cargo compartment. After hearing the prompt, the driver uses the central control panel in the cab to remotely open the slag discharge pneumatic door 3 to unload the slag. During the unloading process, when the mercury level switch 5 detects that the slag loaded in the cargo compartment has reached the designated level, it sends a feedback signal back to the control box 7, triggering the voice playback board to output an alarm prompt and broadcasting "Middle position zone is full, please move the truck" via the loudspeaker 2. After hearing the prompt, the driver uses the central control panel in the cab to remotely close the slag discharge pneumatic door 3 to stop unloading and simultaneously drives the slag-loading truck slowly to the next area, namely the rear position zone, where the detection signal of the vehicle positioning photoelectric switch 4 in the middle position zone disappears.

[0021] When the driver drives the slag-loading truck to the rear position area and stops, the vehicle positioning photoelectric switch 4 located in the rear position area detects that the slag-loading truck has arrived and sends a feedback signal back to the control box 7, triggering the voice playback board to output an alarm prompt and broadcasting "Vehicle in rear position area has arrived" via the loudspeaker 2. At this time, the mercury level switch 5 is still inside the slag-loading truck. After hearing the prompt, the driver uses the central control panel in the cab to remotely open the slag discharge pneumatic door 3 to unload the slag. During the unloading process, when the mercury level switch 5 detects that the slag loaded in the truck has reached the designated level, it sends a feedback signal back to the control box 7, triggering the voice playback board to output an alarm prompt and broadcasting "Rear position area is full, please move the truck" via the loudspeaker 2. After hearing the prompt, the driver uses the central control panel in the cab to remotely close the slag discharge pneumatic door 3 to stop unloading the slag and drives the slag-loading truck away from the slag discharge area. The detection signal of the vehicle positioning photoelectric switch 4 located in the rear position area disappears.

[0022] It is important to note that in the front position zone, if the mercury level switch 5 at the lower hoisting height does not activate within the predetermined unloading time (the unloading time is pre-set), it indicates that the slag bin may be experiencing a blockage at the discharge port. This will trigger the activation of the bin wall vibrator 1 (the operating time is pre-set) to vibrate the bin walls, facilitating smooth material discharge. During subsequent unloading, the driver can remotely activate the bin wall vibrator 1 from the cab at any time. Conversely, if the driver does not move the vehicle to the middle position zone after the mercury level switch 5 activates (i.e., the vehicle positioning photoelectric switch 4 in the middle position zone does not detect the vehicle's arrival signal), the mercury level switch 5 at the higher hoisting height will activate, closing the slag discharge pneumatic door 3. Simultaneously, it will trigger the voice playback board to output an alarm prompt, broadcasting "Slag door closed" via the loudspeaker 2. Upon hearing the prompt, the driver must move the vehicle to the middle position zone and remotely open the slag discharge pneumatic door 3 to restart the unloading process as described above. The same procedure applies if the same situation occurs in the middle or rear position zones.

[0023] It should be noted that, in this application, the specific division of the slag discharge area should be adjustable according to the size of the slag loading truck. For example, it can be set as "front position area - middle position area - rear position area" or "front position area - rear position area", which is flexible and applicable. Similarly, the specific number and installation position of the vehicle positioning photoelectric switch 4 and the mercury level switch 5 should also be adjusted according to the specific division of the slag discharge area.

[0024] In this embodiment, the control box 7 is equipped with a remote controller, which establishes a communication connection with the control box 7 for remotely controlling the bin wall vibrator 1 and the slag discharge pneumatic door 3. Similarly to the remote control via the cab center console, the remote controller operates independently of the center console. In any area, the driver can manually press the remote controller to control the bin wall vibrator 1 and the slag discharge pneumatic door 3, thus improving safety, convenience, and flexibility.

[0025] In this embodiment, an observation mirror 6 is also included. The observation mirror 6 is installed in the slag discharge area and is used to observe the slag loading status of the slag truck compartment. Throughout the slag discharge operation, the driver can use the observation mirror 6 to help judge the slag loading status of the compartment. After the operation stabilizes, it will be used as a manual observation tool in emergency situations.

[0026] In this embodiment, the control box 7 is connected to the remote DCS / PLC control system via Modbus communication to realize remote monitoring and control of the slag discharge operation, thereby improving the safety and remote operability of the slag discharge operation.

[0027] In summary, this utility model addresses the problem that traditional slag bin discharge requires at least two workers, and that communication difficulties between the driver and the discharge operator can easily lead to overflowing slag. It proposes a slag bin discharge control system. Specifically, the discharge area is divided into multiple zones based on the size of the slag truck compartment. Each zone has a vehicle positioning detection system and a slag loading level detection system. Combined with a voice alarm function, the driver can remotely start or stop the discharge process. Simultaneously, the mercury level switch is linked to the bin wall vibrator and the pneumatic discharge door, automatically linking to ensure safe operation under special conditions. This utility model revolutionizes traditional slag discharge control, freeing up manpower and reducing the number of operators (one driver is sufficient), while also preventing overflow and improving discharge efficiency.

[0028] It should be understood that the examples and embodiments described herein are for illustrative purposes only and are not intended to limit the present invention. Those skilled in the art can make various modifications or changes based on them. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
