In view of the above-mentioned problems in the prior art, main purpose of the present utility model is to address the deficiencies of the prior art, and provides a kind of and integrates temperature sense warning, automatic fire prevention, automatic powder spraying fire extinguishing and kitchen exhaust pipeline automatic fire prevention extinguishing device to smoke exhaust fan auto-breaking.
The utility model provides a kind of kitchen exhaust pipeline automatic fire prevention extinguishing device, exhaust fume collecting hood is provided with below the left end of wherein smoke discharging pipe, and the right-hand member of described smoke discharging pipe is provided with smoke exhaust fan, comprise the first temperature sensor, dry powder pipe extinguishing device, dry powder storage tank and control cabinet, described first temperature sensor to be arranged in described smoke discharging pipe and to be positioned at the top of described exhaust fume collecting hood, described smoke discharging pipe inside is also provided with the second temperature sensor and three-temperature sensor, described second temperature sensor is arranged on the position in the middle of described smoke discharging pipe, described three-temperature sensor is arranged on the one end near smoke exhaust fan in described smoke discharging pipe, described dry powder pipe extinguishing device is arranged on the inside of described smoke discharging pipe, described dry powder pipe extinguishing device is connected with described dry powder storage tank by dry powder conveyance conduit, the right side being positioned at described dry powder pipe extinguishing device in described smoke discharging pipe is provided with fire-fighting air-valve, described control cabinet and described first temperature sensor, second temperature sensor, three-temperature sensor, dry powder pipe extinguishing device, fire-fighting air-valve is connected with described smoke exhaust fan, described control cabinet outer setting has a temperature alarm, described temperature alarm is connected with described control cabinet.
Optionally, described smoke discharging pipe is provided with clarifier near the left side of described smoke exhaust fan.
Optionally, the lower end of described dry powder conveyance conduit is connected with described dry powder storage tank bottom, is delivered in dry powder pipe extinguishing device by the dry powder in dry powder storage tank by this dry powder conveyance conduit.
The utility model has the following advantages and beneficial effect: the utility model provides a kind of kitchen exhaust pipeline automatic fire prevention extinguishing device, has following characteristics or advantage:
1, under prior art condition, cannot to catch fire sensed in advance to kitchen exhaust pipeline, what thus prior art condition was carried out is all the passive measure taked after catching fire, and namely once catching fire is exactly the injection that sprays fire extinguisher, or to fetch water in pipeline fire extinguishing with applicator; The utility model by arranging the first temperature sensor and the second temperature sensor in smoke discharging pipe, can the exception of temperature in sensed in advance to smoke discharging pipe, once the first temperature sensor, the second temperature sensor or three-temperature sensor find the exception of temperature in smoke discharging pipe, described temperature alarm realizes reporting to the police, by cutting off the power supply of smoke exhaust fan, contingent fire is made to lose combustion-supporting power; Namely launch the fire prevention of pro-active intervention formula and fire-fighting work by control cabinet simultaneously, contingent fire is shifted to an earlier date the starting stage that anti-lost or elimination is in advance being caught fire;
2, occur in smoke discharging pipe because pipeline catches fire, and smoke discharging pipe shape, length and tendency are different, extinguish material all cannot or can not all be sprayed on fire by existing fire extinguisher and sprinkling fire method, and thus its extinguishing effect is had a greatly reduced quality even does not have effect; Dry powder pipe extinguishing device is directly installed at smoke discharging pipe inside by the utility model, thus dry powder can be sprayed directly on comburant, and utilize high pressure dust fire extinguishing principle stamp out a fire rapidly.
Accompanying drawing explanation
Fig. 1 is the structural representation of kitchen exhaust pipeline automatic fire prevention extinguishing device of the present utility model.
Detailed description of the invention
With specific embodiment, the utility model is further described below with reference to accompanying drawings.
As shown in Figure 1: a kind of kitchen exhaust pipeline automatic fire prevention extinguishing device of the utility model embodiment, exhaust fume collecting hood 1 is provided with below the left end of wherein smoke discharging pipe 2, and the right-hand member of described smoke discharging pipe is provided with smoke exhaust fan 9, comprise the first temperature sensor 5, dry powder pipe extinguishing device 6, dry powder storage tank 4 and control cabinet 3, described first temperature sensor to be arranged in described smoke discharging pipe and to be positioned at the top of described exhaust fume collecting hood, described smoke discharging pipe inside is also provided with the second temperature sensor 11 and three-temperature sensor 12, described second temperature sensor 11 is arranged on the position in the middle of described smoke discharging pipe, described three-temperature sensor 12 is arranged on the one end near smoke exhaust fan in described smoke discharging pipe, described dry powder pipe extinguishing device 6 is arranged on the inside of described smoke discharging pipe, described dry powder pipe extinguishing device 6 is connected with described dry powder storage tank by dry powder conveyance conduit 10, the right side being positioned at described dry powder pipe extinguishing device 6 in described smoke discharging pipe 2 is provided with fire-fighting air-valve 7, described control cabinet 3 and described first temperature sensor 5, second temperature sensor 11, dry powder pipe extinguishing device 6, fire-fighting air-valve 7 is connected with described smoke exhaust fan 9, described control cabinet 3 outer setting has a temperature alarm 13, when described first temperature sensor 5, second temperature sensor 11 or three-temperature sensor 12 find the exception of temperature in smoke exhaust pipe 2, this temperature alarm 13 can realize warning function, the utility model by arranging the first temperature sensor 5 and the second temperature sensor 10 in smoke discharging pipe 1, can the exception of temperature in sensed in advance to smoke discharging pipe, once the first temperature sensor or the second temperature sensor find the exception of temperature in smoke discharging pipe, described temperature alarm realizes reporting to the police, by cutting off the power supply of smoke exhaust fan, contingent fire is made to lose combustion-supporting power, namely launch the fire prevention of pro-active intervention formula and fire-fighting work by control cabinet simultaneously, contingent fire is shifted to an earlier date the starting stage that anti-lost or elimination is in advance being caught fire, simultaneously dry powder extinguishing installation is directly installed at smoke discharging pipe inside by the utility model, thus dry powder can be sprayed directly on comburant, and utilizes the dust principle of fire extinguishing of high pressure to stamp out a fire rapidly.
