Description
Technical Field
[0001] The utility model relates to the technical field of pre-baked anode production, in particular to a fire extinguishing device for a smoke exhaust rack of a roasting furnace. Background Art
[0002] During the roasting process of pre-baked anodes in an open roasting furnace, a large amount of flue gas and waste gas are generated and ash accumulates in the flue, which causes the temperature of the smoke exhaust rack to be too high. Even worse, the sparks caused by the damage of the roasting furnace wall are adsorbed on the inner wall of the smoke exhaust rack, which will cause the inside of the smoke exhaust rack to catch fire. At present, the existing smoke exhaust racks do not have temperature and flame monitoring devices and fire extinguishing devices. It can only be found whether the temperature of the smoke exhaust rack is too high or on fire through on-site inspections. Moreover, the smoke exhaust rack is in a sealed state, and the furnace needs to be stopped to handle the fire. The device of the utility model can give an early warning in time by installing a temperature and flame automatic monitoring device on the smoke exhaust rack, and can achieve the purpose of extinguishing the fire in time by installing a fire extinguishing device. Content of the Utility Model
[0003] The purpose of the utility model is to provide a fire extinguishing device for a smoke exhaust rack of a roasting furnace, which solves the problems mentioned in the background art that it can only be found whether the temperature of the smoke exhaust rack is too high or on fire through manual inspections, and the furnace needs to be stopped to handle the fire.
[0004] The utility model adopts the following technical scheme:
[0005] A fire extinguishing device for a smoke exhaust rack of a roasting furnace of the utility model includes a water tank, an alarm device, a controller, a fire extinguishing device and a monitoring device. The alarm device, the controller and the fire extinguishing device are arranged on the side wall of the water tank, and the monitoring device is arranged in the smoke exhaust rack.
[0006] The fire extinguishing device includes a water pump. The water pump is connected to the water tank, and the water pump is connected with a first nozzle and a second nozzle through pipelines. The first nozzle and the second nozzle are arranged in the smoke exhaust rack.
[0007] The alarm device, the monitoring device and the water pump are all electrically connected to the controller.
[0008] Further, the alarm device is an audible and visual alarm light.
[0009] Further, the monitoring device includes a first detector, a second detector and an electric contact thermometer. The first detector, the second detector and the electric contact thermometer are all arranged on the inner side wall of the smoke exhaust rack.
[0010] Further, the first detector and the second detector are both flame monitors.
[0011] Still further, a lifting hook is arranged on the water tank.
[0012] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:
[0013] The present utility model utilizes a monitoring device to automatically monitor and alarm, eliminating the need for personnel patrols, achieving audible and visual alarm reminders, enabling operators to promptly discover when the smoke exhaust rack catches fire or the temperature is too high, and being able to conduct on-line fire extinguishing of the equipment immediately through the installed fire extinguishing device without shutting down the furnace, preventing personnel from approaching the smoke exhaust rack under unclear circumstances and avoiding danger.

Detailed Embodiment
[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clearly understood, the present utility model will be further described in detail below in conjunction with the drawings and embodiments.
[0019] As Figure 1 and Figure 2 shown, in this embodiment, a fire extinguishing device for a roasting furnace smoke exhaust rack is disclosed, which includes a water tank 1, an alarm device 3, a controller 4, a fire extinguishing device 5 and a monitoring device 6. The alarm device 3, the controller 4 and the fire extinguishing device 5 are arranged on the side wall of the water tank 1, and the monitoring device 6 is arranged inside the smoke exhaust rack 7.
[0020] The fire extinguishing device 5 includes a water pump 5-1. The water pump 5-1 is connected to the water tank 1, and the water pump 5-1 is connected with a first spray head 5-2 and a second spray head 5-3 through pipelines. The first spray head 5-2 and the second spray head 5-3 are arranged inside the smoke exhaust rack 7.
[0021] The alarm device 3, the monitoring device 6 and the water pump 5-1 are all electrically connected to the controller 4.
