Technical field:
The utility model relates to an oil burner, in general, a burner nozzle with a high pressure oil pump and a high pressure fan required for fuel combustion.The processing technology of this part is complex, the precision is strict, the production cost is high, in the use of the process, the quality of fuel is very high.For example, the LT series burners manufactured by Japan's Olympia industries require 18-21 high-pressure oil pumps and fans at industrial atmospheric pressure, and the burners' core of four oil slots, oil groove conical spiral, with complex processing technology and strict precision requirements, and high production costs.In practical applications, it is easy to produce carbon deposition in the burner nozzle block the fuel tank, so that the entire burner scrap.
The purpose of the utility model is to design a fuel burner whose flame length can be adjusted.Fuel burner works normally, complete combustion is achieved through the configuration of medium and low pressure oil pump and fan.Structure is easy to replace and maintain, simple production process, low cost, and economic and practical.
The utility model includes a combustion nozzle, a piezoelectric igniter and a burner shell device assembly.The combustion nozzle device consists of a nozzle body, a combustion disk, a nozzle connection pipe and a sliding flame to regulate the cylinder liner at the outside diameter of the inlet cylinder.The nozzle body assembly consists of an oil nozzle body, an atomizing disk, an increased pressure plate, an oil inlet groove and a powder copper strainer pressing nut.The nozzle body is provided with an atomizing chamber at the front end of a flat diffusion chamber with a blunt trumpet shape and an external diameter of external threads and internal holes at the rear end of the atomizing chamber.Provided by internal and external threads of nozzle body end-wall.There is an oil injection hole in the center of the atomizing plate and the hole of the atomizing plate into the oil nozzle body and close to the back wall of the atomizing hole cavity.The gas pedal has a spiral opening, which is temporarily small outside the circle of the center to the center hole, and the oil door plate is connected to the atomizing disc.The effect of the screw port is to further increase fuel pressure.The upward pressure velocity of the oil inlet groove increases the pressure booster plate, and the oil inlet groove has a t-shaped oil hole oil passage.The news nut of the filter screen of the powder copper filter screen connects the compression nut as a whole, reducing the number of parts for easy assembly.Clamp the inner hole of the nut.Powder copper strainer pressing nut compression atomizing plate, accelerating pressure increasing plate and oil groove into the nozzle body to form the nozzle body components.The front end of the nozzle body is connected with the thread of the combustion plate, and the back end is connected with the front end of the nozzle connection pipe.The piezoelectric ignition device consists of a convex ceramic tube, a positive core, and a compression spring for electrical conductivity.The outer wall of the combustion tray is equipped with 3 adjusting screws even split.The combustion tray has been installed with combustion nozzle assembly and piezoelectric igniter installation hole.There are several swirling combustion pan air holes, evenly distributed across the combustion pan in the axial direction of the alpha Angle and the alpha Angle is 20-70°.The fuel burner housing assembly consists of a flame regulating cylinder, intake cylinder, luminescent plate and fixing bolt.The inlet cylinder is connected to the flange plate by fixing bolts, and the flame adjusting cylinder liner is in the cylinder and can be adjusted by axial sliding, so that the flame adjusting cylinder can be prolonged or shortened to meet the requirements of a variety of flames.
