The purpose of this utility model is achieved in that
A kind of direct injection combustion device, comprise burner, air jet pipe and Fen Huogai, be provided with air cavity in the burner, the burner top is provided with the air nozzle that is communicated with air cavity, the air nozzle wall is provided with gas mixed hole, and the air jet pipe lower end is connected with air nozzle, it is characterized in that: described burner periphery is provided with cover body, the corresponding air jet pipe of cover body end face offers resigning hole, and the air jet pipe upper end passes resigning hole and is connected with dividing the fire lid.
The purpose of this utility model can also adopt following technical measures to solve:
As scheme more specifically, when described cover body and burner bottom maintained an equal level, the cover body end face was positioned at the middle part of air jet pipe.
Described air cavity comprises center air cavity and outer shroud air cavity, and the burner periphery is provided with center air cavity air inlet pipe and outer shroud air cavity air inlet pipe; Air jet pipe comprises center air jet pipe and peripheral air jet pipe, and the center air jet pipe is provided with one, also is communicated with the center air cavity by an air nozzle, and peripheral air jet pipe is laid with many, and the peripheral air jet pipe of each root is communicated with the outer shroud air cavity by an air nozzle respectively; Divide the fire lid to comprise that center branch fire lid and outer shroud divide fire to cover, center Fen Huogai is threaded with center air jet pipe upper end, and outer shroud divides the fire lid to be arranged on the peripheral air jet pipe.
Described outer shroud divides the outer ring surface of fire lid to be surrounded by the multistage camber line, and inner ring surface extends spoke to center air jet pipe direction.Outer shroud divides the outer ring surface of fire lid to be petal-shaped, makes the girth of outer ring surface greater than the circular perimeter concentric with it, and firepower is bigger.
Described outer shroud divides fiery hd top face to be laid with many spacing bars.
Described air nozzle is threaded with burner.
The beneficial effects of the utility model are as follows:
(1) this kind of burner is provided with cover body above burner, effectively avoids foreign material to fall to burner, and the gas mixed hole that prevents air nozzle stops by foreign material and prevent that air nozzle from being stopped up by foreign material, uses saferly, more can improve the fuel gas buring rate, avoids causing energy waste;
When (2) cover body was installed and used, its end face was positioned at the air jet pipe center, and long air jet pipe is had certain booster action, improved the structural strength of air jet pipe, effectively reduced the diastrophic risk of air jet pipe.
