Description

Technical Field

[0001] The present application relates to the technical field of bottom-blowing furnace smelting, and in particular to an automatic lifting device for a smoke hood insert plate. Background Art

[0002] The pyrometallurgical plant's smelting furnace uses a banana hood for flue gas collection. When the smelting furnace is shut down, the flue gas from the smelting furnace exhaust port is collected and processed through the banana hood to achieve standard emission. During the normal smelting process, the hood plug plate falls to the production position, and the flue gas from the smelting furnace exhaust port directly enters the waste heat boiler for cooling and waste heat utilization.

[0003] In the event of a sudden power outage, the automatic roll-out mechanism of the bottom-blown furnace is activated. However, since the smoke hood plug-in plate is manually lifted, manual operation is required. At the same time, the smoke exhaust fan also stops running due to the power outage, the on-site environment becomes chaotic, and the vision is blurred, making it more difficult to handle emergencies. Under such special conditions, the staff's operation is restricted, and it is difficult to manually lift the smoke hood plug-in plate at the furnace mouth into place before the bottom-blown furnace is rolled out. During a power outage, the sudden rotation of the bottom-blown furnace will cause damage to the plug-in plate water jacket and the membrane wall of the waste heat boiler, and even leakage, resulting in equipment damage and safety hazards.

[0004] Based on the above problems, it is necessary to strengthen the research on the automatic lifting of the smoke hood plug plate in the event of a power outage to ensure effective response when an emergency occurs, reduce the risk of accidents, and ensure the safety of production equipment and personnel.

[0047] Figure 4 It is a structural schematic diagram of the control box in the embodiment of the present application.

[0048] See also Figure 1-4 , an automatic lifting device for a smoke hood plug board, used for lifting the smoke hood plug board, comprising: an electric hoist 1, a steel cable 2, a controller 3, a backup power supply 4 and a power-off switch 5;

[0049] The controller 3 is a PLC controller, the backup power supply 4 is a UPS power supply system, and the power-off switch 5 is a dual-power automatic switch.

[0050] The electric hoist 1 is connected to the smoke hood plug-in plate 8 through a steel cable 2 to achieve the hoisting of the smoke hood plug-in plate;

[0051] An electrical connection is established between the backup power supply 4 and the power-off switch 5;

[0052] The power-off switch 5 is electrically connected to the electric hoist 1 and the controller 3 respectively;

[0053] The controller 3 is electrically connected to the bottom blowing furnace main control.

[0054] In this embodiment, the electric hoist 1 is connected to the smoke hood plug-in plate 8 through the steel cable 2, and the smoke hood plug-in plate can be lifted by driving the electric hoist 1.

[0064] An electrical connection is established between the second photoelectric sensor 7 and the power-off switch 5;

[0065] An electrical connection is established between the controller 3 and the second photoelectric sensor 7 .

[0066] By setting the second photoelectric sensor 7, when the controller 3 receives the detection signal of the second photoelectric sensor 7, the controller 3 will stop the descent of the electric lift 1, thereby controlling the descending position of the smoke hood plug-in plate 8. This can ensure that the smoke hood plug-in plate 8 stops descending when it reaches a specific height, thereby effectively controlling the position and movement of the smoke hood plug-in plate 8.

[0067] Specifically, in the embodiments of the present application,

[0068] The smoke hood plug plate 8 is provided with two hanging ears 801;

[0069] One end of the steel cable 2 is provided with a hook for connecting and fixing with the hanging ear 801 .

[0070] By providing the hanging ears and the hooks, the smoke hood plug plate 8 and the steel cable 2 can be installed more conveniently, and the stability of the smoke hood plug plate 8 can also be ensured, thereby ensuring the overall installation quality.

[0074] The control box 9 is provided with a keypad 901, and an electrical connection is established between the keypad 901 and the controller 3. The keypad 901 is provided with an up and down button.

[0075] By providing the control box 9, the controller 3 can be protected from the external environment, and the operator can control the rise and fall of the smoke hood plug plate 8 through the buttons on the keypad 901, thereby improving the convenience of operation.

[0076] The embodiments of the present application include the following beneficial effects:

[0077] The automatic lifting device for the fume hood plug plate of the present application can automatically lift the fume hood plug plate 8 in the event of a sudden power outage, thereby ensuring the safety of production equipment and personnel.

[0078] The present application combines the controller 3, the backup power supply 4 and the power-off switch 5 to ensure that the electric hoist 1 can operate normally even when there is a power outage to drive the smoke hood plug plate 8. The present application can effectively control the position and movement of the smoke hood plug plate 8 by setting the first photoelectric sensor 6 and the second photoelectric sensor 7, thereby improving the safety of the operation.

[0079] The automatic lifting device for the smoke hood plug plate in the embodiment of the present application has a good operating effect after being put into use. When the city power is cut off, the smoke hood plug plate 8 can be automatically lifted to a safe position in four seconds, ensuring that the bottom blowing furnace can be safely turned out when there is a sudden power outage.
