[0018] In order to enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below in conjunction with the drawings in one or more embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this document.

[0019] When the blast furnace slag is turned over, the slag pot power supply is connected to the cable through industrial aviation plugs, welding pliers and other tools to form a circuit to drive the slag pot to move. The operation point is fixed, and the operator can only control it through the electrical control panel in the electrical room. At the same time, the operator's vision is blocked due to the long distance between the slag pot truck and the operator's working line of sight. When tipping over, the tipping angle of the slag pot, the crust on the surface of the slag pot, the slag discharge flow rate, etc. cannot be visually observed and controlled, resulting in red slag splashing and splattering, and even liquid slag explosion accidents due to improper operation and inadequate safety confirmation.

[0020] In order to solve the above problems, the embodiment of the present disclosure provides a remote wireless remote control system for blast furnace slag turning operation, the structural diagram of which is as follows: Figure 1 As shown, it mainly includes: a wireless remote control 10, which is used to issue control instructions; a receiver 20, which is paired with the wireless remote control 10 and is used to receive the control instructions issued by the wireless remote control 10; a drive system 30, which is connected to the receiver 20 through a cable and is used to execute the control instructions to complete the preset actions corresponding to the control instructions. Figure 1 As shown in the figure, the wireless remote controller 10 and the receiver 20 are connected by a dotted line, indicating that the two communicate via a wireless transmission protocol, and the receiver 20 and the drive system 30 are connected by a solid line, indicating that the two are connected using a physical cable.

[0021] Specifically, the driving system 30 is connected with the slag pot to drive it to perform the tilting operation, and at least includes a motor, a residual current operating circuit breaker, a power module, a forward rotation AC contactor, a reverse rotation AC contactor and a self-locking device; wherein, when the motor is started, in combination with the forward rotation or reverse rotation condition, the slag pot is tilted in different directions; the residual current operating circuit breaker is used as a controller for the power-on of the motor, and when it is closed, the motor is connected with the power module to complete the power-on, and when it is disconnected, the motor is also in a power-off state and cannot be operated; when the forward rotation AC contactor or the reverse rotation AC contactor is closed, the motor performs the forward rotation or reverse rotation operation correspondingly; and the self-locking device is used to stop the rotation of the motor in an emergency state to maintain the current tilting state of the slag pot.

[0022] The wireless remote controller 10 and the receiver 20 are paired devices, so that the receiver 20 can accurately receive the instructions sent by the wireless remote controller 10; and the receiver 20 is connected with the driving system 30 through a cable. The wired connection mode is used to ensure the stability of the connection between the two and facilitate the switching between the receiver 20 and different driving systems 30. In fact, there may be multiple slag pots in the slag dumping area of the blast furnace, and each slag pot actually corresponds to a set of driving system 30. When it is actually necessary to operate one of the slag pots, the receiver 20 is connected with the corresponding driving system 30 through a cable, and the driving system 30 can be controlled by the wireless remote controller 10 held by the operator. When the current slag pot is finished dumping and needs to be switched to the next slag pot, the operator can directly disconnect the receiver 20 from the current driving system on site and connect it with the driving system of the next slag pot through a cable, without the need for feedback electrical operation to control the operation.

[0023] The wireless remote controller 10 of the embodiment at least includes a controller, a wireless communication module, a button module and a remote controller power supply. The button module at least includes a start button, a closing button, an opening button, a forward rotation button, a reverse rotation button and an emergency stop button, as shown in Figure 2 Specifically, the start button is a function button for controlling the power-on of the wireless remote controller 10. When the start button is pressed, the controller is connected with the remote controller power supply, and the wireless remote controller is powered on. At this time, by pressing other buttons, the controller will generate the control instructions corresponding to the buttons and send them through the wireless communication module. If the controller is not powered on, the control instructions will not be generated even if the other buttons are pressed.

[0024] In the actual operation process, when the closing button is pressed, the controller generates a closing instruction, and the driving system 30 drives the residual current operating circuit breaker to close, so that the motor is connected with the power module to be powered on. When the opening button is pressed, the controller generates an opening instruction, and the driving system 30 drives the residual current operating circuit breaker to open, so that the motor is disconnected with the power module.

[0025] When the forward rotation button is pressed, the controller generates a forward rotation instruction, and the driving system 30 drives the forward rotation AC contactor to close, so that the motor rotates forward; when the forward rotation button is released, the controller stops generating the forward rotation instruction, and the driving system 30 drives the forward rotation AC contactor to open. When the reverse rotation button is pressed, the controller generates a reverse rotation instruction, and the driving system 30 drives the reverse rotation AC contactor to close, so that the motor rotates reversely; when the reverse rotation button is released, the controller stops generating the reverse rotation instruction, and the driving system 30 drives the reverse rotation AC contactor to open.

[0026] In actual operation, if an emergency occurs, such as motor forward and reverse rotation failure, the slag pot can be stopped urgently by pressing the emergency stop button. When the emergency stop button is pressed, the controller generates an emergency stop instruction, and the driving system drives the self-locking device to start, and the motor is urgently braked by the self-locking device to stop the subsequent action of the slag pot.

[0027] In some embodiments, the residual current operating circuit breaker can be implemented by selecting a residual current operating circuit breaker of model PSM7EL-250 / 3N. The wireless remote controller 10 can be customized according to actual appearance requirements, for example, a remote controller of model F21-6S+TX is used as a base body for customization, including a controller, a wireless communication module, a button module, and a remote controller power supply and other components. The controller can be implemented by selecting a single-chip microcomputer of model STM32F051R8T6, or other single-chip microcomputers or microprocessors with the same function, which are not limited in the embodiment. The wireless communication module can execute any one of Bluetooth communication protocol, Zigbee communication protocol, and infrared communication protocol to realize its wireless communication function. The corresponding receiver needs to be set according to the communication protocol used in the remote controller. In addition, the remote controller power supply can select a No. 5 or No. 7 dry battery, or a button battery.

[0028] The embodiment utilizes the wireless remote controller that can be remotely controlled to send control instructions, which are connected through the receiver, and further combined with the cable to realize the communication between the receiver and the driving system for controlling the slag pot to be tilted, so that the tilting operation of the slag pot can be realized by the operator holding the wireless remote controller on site, and the slag pot is adjusted in real time by observing the tilting, slagging, and flow rate of the slag pot, so that the liquid explosion accident is effectively avoided or eliminated.

[0029] Now, the operation of the original manual electrical operation panel and the operation of the wireless remote control system of the embodiment are compared:

[0030] Work efficiency: the length of the slag turning operation path is 150 meters, taking 14 slag pots as an example, the operator needs to connect the wire and the wire pile of each slag pot, and then returns to the operation room to operate the pot turning on the electrical operation panel. Because the distance between the volume end and the operation end is far, the operator needs to walk back and forth to connect and disconnect the wire of 14 slag pots, which affects the work efficiency. The wireless remote control system of the embodiment has small size, light weight and convenient carrying, and the operator can hang the remote control on the body, which can improve the work efficiency by operating on site and cooperating with the wire connection and disconnection.

[0031] Safety: the original operation mode is that the operator operates in the operation room through the buttons on the distribution panel. Because the length of the slag pot car is long, the slag pots at both ends cannot be well controlled in the angle and cannot be intuitively observed in the slag flow size during the tilting process due to the influence of the line of sight, which is easy to cause red slag splashing, spattering and liquid slag explosion accidents, leading to the ignition of the surrounding green area, and even causing personnel burns. Through the operation mode of the wireless remote control system of the embodiment, the operator can operate the pot turning through remote control at a safe distance of 10 meters from the slag pot, can intuitively observe the tilting angle of the slag pot and the size of the slag flow during slagging, and can effectively control the flow rate to prevent safety accidents.

[0032] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present disclosure, but not to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure.
