DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] The present embodiment provides an automatic cleaning and fire extinguishing system for an oil fume duct 10, which can clean and extinguish the oil fume duct 10 respectively. The temperature in the oil fume duct 10 is monitored by a sensing component 20 arranged in the oil fume duct 10. When the temperature in the oil fume duct 10 exceeds a predetermined value, the main control component 50 controls the fire extinguishing component 40 to start and extinguish the fire in the oil fume duct 10 to avoid explosion in the oil fume duct 10, thereby avoiding threats to surrounding personnel and buildings.

[0027] Combination Figures 1 to 3 As shown, the automatic cleaning and fire extinguishing system of the oil fume duct 10 of this embodiment includes the oil fume duct 10, a sensing component 20, a cleaning assembly 30, a fire extinguishing assembly 40 and a main control component 50. The sensing component 20 is arranged in the oil fume duct 10 to sense the temperature in the oil fume duct 10 in real time, and the cleaning assembly 30 and the fire extinguishing assembly 40 can clean and extinguish the oil fume duct 10 respectively. The main control component 50 can receive and transmit signals to realize all-round control of the system.

[0028] In the present embodiment, the number of sensing components 20 is at least one group and they are arranged in the oil fume duct 10 to monitor the temperature state in the oil fume duct 10. The sensing component 20 in the present embodiment is a temperature sensing cable. The temperature sensing cable is along the length direction of the oil fume duct 10 and is evenly distributed in the oil fume duct 10. The temperature sensing cables evenly distributed in the oil fume duct 10 can monitor the temperature of various places in the oil fume duct 10 in real time, and transmit the monitored temperature data to the main control component 50. When the temperature in the oil fume duct 10 exceeds a predetermined value, the main control component 50 will control the fire extinguishing component 40 to start after receiving the temperature data, and extinguish the fire in the oil fume duct 10 to avoid serious consequences due to untimely fire extinguishing. The temperature sensing cable in the present embodiment can be installed in the oil fume duct 10 or float in the air.

[0029] Combination Figure 1 and Figure 2 As shown, the cleaning assembly 30 includes a cleaning liquid supply box 31 and a cleaning nozzle 32. The cleaning nozzle 32 extends into the oil fume duct 10, sprays the cleaning liquid into the oil fume duct 10, and cleans the inside of the oil fume duct 10. The fire extinguishing assembly 40 includes a fire extinguishing liquid supply box 41 and a fire extinguishing nozzle 42. The fire extinguishing nozzle 42 and the cleaning nozzle 32 are the same nozzle. The cleaning liquid supply box 31 of this embodiment is filled with oil dispersant, and the fire extinguishing liquid supply box 41 is filled with fire extinguishing agent. When it is necessary to clean the inside of the oil fume duct 10, the fire extinguishing assembly 40 includes a fire extinguishing liquid supply box 41 and a fire extinguishing nozzle 42. The fire extinguishing nozzle 42 and the cleaning nozzle 32 are the same nozzle. When cleaning is performed, the cleaning component 30 is started, and the oil dispersant is sprayed out through the cleaning nozzle 32 and enters the oil fume duct 10 to clean the inside of the oil fume duct 10. When the temperature in the oil fume duct 10 exceeds a predetermined value, the fire extinguishing component 40 is started, and the fire extinguishing agent is sprayed out through the fire extinguishing nozzle 42 and enters the oil fume duct 10 to extinguish the fire. The fire extinguishing nozzle 42 and the cleaning nozzle 32 of this embodiment are the same nozzle, which integrates the cleaning function and the fire extinguishing function, reduces the assembly cost of the system, and improves practicality.

[0030] Furthermore, in the present embodiment, a liquid level switch 80 is provided in the cleaning liquid supply box 31 and the fire extinguishing liquid supply box 41 to monitor the liquid levels in the cleaning liquid supply box 31 and the fire extinguishing liquid supply box 41. When the oil dispersant in the cleaning liquid supply box 31 or the fire extinguishing agent in the fire extinguishing liquid supply box 41 is insufficient, the liquid level switch 80 will be opened, and under the action of the external conveying device, the cleaning liquid supply box 31 or the fire extinguishing liquid supply box 41 will be automatically replenished with liquid to prevent the cleaning liquid supply box 31 or the fire extinguishing liquid supply box 41 from being insufficient, which may affect the smooth progress of the cleaning or fire extinguishing operation.

[0031] In this embodiment, the main control component 50 is electrically connected to the sensing component 20, the cleaning component 30 and the fire extinguishing component 40 for information exchange and control. The main control component 50 in this embodiment is a control circuit board that receives and transmits signals to achieve comprehensive control of the system.

[0032] The automatic cleaning and fire extinguishing system of the oil fume duct 10 of the present embodiment further comprises a main frame 60 , on which the cleaning liquid supply box 31 and the fire extinguishing liquid supply box 41 are both arranged.

[0033] Combination Figure 2 and Figure 3 As shown, a water pump 61 is provided in the main frame 60, and the water pump 61 is respectively connected to the cleaning liquid supply box 31 and the fire extinguishing liquid supply box 41 through the connecting pipe 70. Under the action of the water pump 61, the liquid in the cleaning liquid supply box 31 or the fire extinguishing liquid supply box 41 can be pumped out to clean or extinguish the oil fume duct 10.

[0034] In this embodiment, the cleaning nozzle 32 is connected to the water outlet of the water pump 61, and the water pump 61 delivers the extracted liquid into the cleaning nozzle 32, and the cleaning nozzle 32 sprays the corresponding liquid to clean or extinguish the oil fume duct 10.

[0035] Furthermore, a first solenoid valve 71 and a second solenoid valve 72 are provided on the connecting pipeline 70. The first solenoid valve 71 is located at the outlet end of the cleaning liquid supply box 31 to control the opening and closing of the cleaning nozzle 32. The second solenoid valve 72 is located at the outlet end of the fire extinguishing liquid supply box 41 to control the opening and closing of the fire extinguishing nozzle 42. The first solenoid valve 71 and the second solenoid valve 72 of this embodiment are both controlled by the main control component 50, and the main control component 50 can control the cleaning component 30 and the fire extinguishing component 40 respectively through the first solenoid valve 71 and the second solenoid valve 72 to clean or extinguish the oil fume duct 10.

[0036] In actual use of the automatic cleaning and fire extinguishing system for the oil fume duct 10 of this embodiment, the cleaning component 30 can spray the oil dispersant through the cleaning nozzle 32 to clean the oil stains in the oil fume duct 10. When the temperature in the oil fume duct 10 exceeds a predetermined value, the main control component 50 controls the second solenoid valve 72 to open after receiving the temperature data, and the fire extinguishing agent in the fire extinguishing liquid supply box 41 is extracted by the water pump 61 and sprayed into the oil fume duct 10 by the fire extinguishing nozzle 42 to extinguish the fire in the oil fume duct 10, thereby avoiding serious consequences due to untimely fire extinguishing.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
