Description

Technical Field

[0001] This utility model relates to the field of calcium carbide furnace silo feeding technology, and in particular to a high-precision automatic silo positioning device for calcium carbide furnaces. Background Technology

[0002] The current silo feeding system of the calcium carbide furnace batching station transports lime, semi-coke, and coke to the corresponding silos by moving a mobile device to change the position of the conveyor belt. It has both local and remote operation modes. However, during remote operation, the control room personnel cannot see the on-site equipment and need on-site personnel to assist, which makes operation inconvenient. Therefore, the current main method is for operators to start and stop the equipment at the machine and keep an eye on the mobile device, stopping the mobile device at the feed silo position.

[0003] Two main problems were exposed during this process: First, the feeding mobile device was entirely dependent on manual operation. When starting the conveyor belt, the electrician in the central control room had to use a walkie-talkie to call the belt inspector on the fourth floor of the calcium carbide furnace batching station to operate the button distribution box. Each time the belt was started, the inspector had to go to the fourth floor. Moreover, the environment at the feeding site was harsh, with dust and noise seriously damaging the health of the inspector, making it unsuitable for long-term on-site duty. Second, the moving speed of the mobile device was too fast when operated manually, making it difficult to align with the bin in one go. The position of the mobile device had to be adjusted frequently, which had an adverse effect on the feeding efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to control the moving speed of the feeding moving device through the central control room, so that the feeding moving device can accurately align with the bin and complete the material delivery.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a high-precision automatic positioning device for calcium carbide furnace, including a moving device, a hopper, a ranging device, a PLC control device, a transceiver, a PC terminal and a frequency converter. The mobile device is positioned above the silo and is equipped with a conveyor belt. The mobile device moves forward or backward in the direction in which the silo is located. The ranging device is located at the extension line of the centerline of the moving device track, and the ranging device is electrically connected to the PLC control device; The frequency converter is installed on the drive motor of the mobile device and is electrically connected to the PLC control device. The PLC control device and the PC terminal are connected via fiber optic cable through a transceiver.

[0006] The beneficial effects of this utility model are: it realizes remote automated control of the feeding system, reduces on-site manual operation by more than 80%, and significantly reduces the labor intensity and health risks of on-site personnel.

[0007] The positioning accuracy of the mobile device has been significantly improved, with a one-time alignment success rate of over 95%, and the material loading efficiency has been increased by about 30%.

[0008] This will improve the production stability and management level of the entire calcium carbide furnace batching station, reduce the incidence of production accidents caused by human factors, and bring good economic and social benefits to the enterprise.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the transceiver is equipped with a first transceiver and a second transceiver. The first transceiver is located in the field power distribution room and is electrically connected to the PLC control device. The second transceiver is located in the cabinet room and is electrically connected to the PC terminal. The first transceiver and the second transceiver are connected by optical fiber.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by electrically connecting the PLC control device to the PC terminal through the first and second transceivers, workers can send commands to the PLC control device via the PC terminal. The PLC control device receives data from the ranging device, calculates the position of the moving device in real time, and controls the frequency converter to adjust the speed and direction of the moving device according to a preset program, thereby reducing the inertial travel distance when the moving device stops. This ensures that it is accurately aligned with the designated position of the hopper. The PC terminal monitors and records the operation data in real time, achieving automated and efficient management.

[0012] Furthermore, the conveyor belt installed on the mobile device is a reversible belt.

[0013] The advantage of adopting the above-mentioned further solution is that the conveyor belt installed on the mobile device is a reversible belt. Through the forward conveying and reverse vertical movement of the belt, the mobile device can transport materials to the hoppers at both ends of the mobile device.

[0014] Furthermore, the ranging device is a laser rangefinder.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by installing a high-precision laser rangefinder on the mobile device for positioning, and combining it with the positioning algorithm in the control system, the mobile device can be accurately positioned. The positioning accuracy can be controlled within ±5 cm, ensuring that it can be aligned with the warehouse position in one go.

[0016] Furthermore, the ranging device is set two meters from the centerline extension of the mobile device's track via a ranging instrument bracket.

[0017] The ranging device is fixed to the rangefinder bracket with screws, and the ranging device can be vertically set above the head cover of the mobile device.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the mobile device is started on the PC terminal, the position of the mobile device is determined according to the signal transmitted by the rangefinder, and the PLC program determines that the mobile device will automatically stop when it reaches the required position.

[0019] Furthermore, the mobile device, ranging device, transceiver, and frequency converter are all electrically connected to the PC terminal and PLC control device.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the PLC control device receives data from the ranging device, calculates the position of the moving device in real time, and controls the frequency converter to adjust the speed and direction of the moving device according to the preset program, thereby reducing the inertial travel distance when the moving device stops. This ensures that it is accurately aligned with the designated position of the hopper, and the PC terminal monitors and records the operation data in real time, realizing automated and efficient management.

[0021] Furthermore, multiple silos are provided, and the multiple silos are arranged side by side on the travel route of the mobile device. The mobile device moves forward or backward along the direction in which the multiple silos are located.

[0022] The beneficial effect of adopting the above-mentioned further solution is that when the mobile device moves to one of the hoppers, the material in the mobile device can be transported to the hoppers at both ends of the mobile device by the forward and reverse rotation of the belt.

[0023] Furthermore, the PLC control device is located in the central control room.

[0024] The beneficial effect of adopting the above-mentioned further solution is that by setting the PLC control device in the central control room, a human-machine interface can be realized in the central control room, making its operation simpler and more intuitive. Important data such as equipment status, alarm information, and feeding progress are centrally displayed on one interface, making it easy for operators to grasp the operation of the entire feeding system at a glance.

[0025] Furthermore, a PC terminal is set up on-site.

[0026] The advantage of adopting the above-mentioned further solution is that the PC terminal is set up on-site, mainly for monitoring and controlling the mobile device and displaying the operating status of the ranging device and the frequency converter. Attached Figure Description

The mobile device 1 is positioned above the hopper 2. The mobile device 1 is equipped with a conveyor belt and moves forward and backward in the direction in which the hopper 2 is set. The ranging device 3 is located at the extension line of the centerline of the track of the moving device 1, and the ranging device 3 is electrically connected to the PLC control device 4; The frequency converter 8 is installed on the drive motor of the mobile device 1, and the frequency converter 8 is electrically connected to the PLC control device 4. The PLC control device 4 is connected to the PC terminal via a transceiver using optical fiber.

[0031] Specifically, when the mobile device 1 rotates forward to position 1#, the belt rotates forward and the material on the belt is fed into the discharge port; when the mobile device 1 rotates forward to position 1#, the belt reverses and the material is fed into hopper 2#; when the mobile device 1 reverses to position 1#, the belt rotates forward and the material is fed into hopper 2#; when the mobile device 1 reverses to position 2#, the belt reverses and the material is fed into hopper 2#.

[0032] In this embodiment, the frequency of the inverter 8 is set to 20Hz.

[0033] In this embodiment, the preset program of the PLC control device 4 is existing technology and will not be described in detail here.

[0034] Based on the above technical solution, the present invention can be further improved as follows.

[0035] like Figure 1 As shown, the transceiver includes a first transceiver 5 and a second transceiver 6. The first transceiver 5 is located in the field power distribution room and is electrically connected to the PLC control device 4.

[0036] Specifically, the PLC control device 4 is electrically connected to the PC terminal 7 via the first transceiver 5 and the second transceiver 6. This allows workers to send commands to the PLC control device 4 through the PC terminal 7. The PLC control device 4 receives data from the ranging device 3, calculates the position of the moving device 1 in real time, and controls the frequency converter 8 to adjust the speed and direction of the moving device 1 according to a preset program. This reduces the inertial travel distance of the moving device 1 when it stops, ensuring precise alignment with the designated position in the hopper 2. The PC terminal 7 monitors and records the operation data in real time, achieving automated and efficient management.

[0042] like Figure 1 As shown, the ranging device 3 is set two meters from the centerline extension of the track of the mobile device 1 via a rangefinder bracket.

[0043] The ranging device 3 is fixed to the rangefinder bracket by screws, and the ranging device 3 can be vertically set above the head cover of the moving device 1.

[0044] Specifically, the mobile device 1 is started on the PC terminal. The position of the mobile device 1 is determined based on the signal transmitted by the rangefinder. The PLC program determines the position and automatically stops the mobile device 1 when it reaches the required position.

[0045] In this embodiment, when the mobile device 1 is about to move to the position of the ranging device 3, the top of the head cover of the mobile device 1 is perpendicular to the ranging device 3, which is equivalent to having a camera installed on the top of the head, with the camera vertically above the head.

[0046] like Figure 1 As shown, the mobile device 1, the ranging device 3, the transceiver and the frequency converter 8 are all electrically connected to the PC terminal 7 and the PLC control device 4.

This ensures that it is accurately aligned with the designated position of the hopper 2. The PC terminal 7 monitors and records the operation data in real time, realizing automated and efficient management.

[0048] like Figure 1 As shown, there are multiple hoppers 2, which are arranged side by side on the track of the moving device 1. The moving device 1 moves forward or backward along the direction in which the multiple hoppers 2 are arranged.

[0050] like Figure 1 As shown, the PLC control device 4 is located in the central control room.

[0051] Specifically, the PLC control device 4 is located in the central control room, enabling a human-machine interface that makes operation simpler and more intuitive.
