Description
Technical field
The utility model belongs to technical field of burner, more particularly, to a kind of outer circulation low NO.
Background technique
Outer circulation low NO is one kind of metal fiber burner, belongs to the burning of premixed gas surface, mixed in advance
It closes uniform gas-air mixture and flows to burner head, fired in the uniform metal fibre interlacement superficial layer of gas permeability
It burns.When being premixed to air and fuel, precision has been carried out to regulation and control, has guaranteed being thoroughly mixed for the air of combustion gas,
Keep burning more abundant, pre-mixing type combustion apapratus exists because air filter blocks, and air inlet windage is caused to become larger, and reduces blower work effect
The problem of rate, and when blocking to a certain extent, the mixed proportion of air and combustion gas much deviates preset value, it will caused safety
Problem.
Utility model content
The purpose of this utility model is the deficiencies in the prior art place to be solved, and is provided a kind of with prompting function, peace
The high outer circulation low NO of full performance.
The purpose of this utility model is solved through the following technical scheme:
A kind of outer circulation low NO, it is characterised in that: including blower, mixing drum and combustion barrel；It is equipped on the right side of blower
Air inlet, air inlet are equipped with filter and servo motor, and the blower motor of driving blower is equipped on the left of blower, is on rear side of blower
Blower inner cavity, blower inner cavity rear side is air outlet, and air outlet is connect with mixing drum, and mixing drum is equipped with fuel gas inlet, mixing drum
Rear side is equipped with combustion barrel, is equipped with fire rod on the outside of combustion barrel；
The blower inner cavity is equipped with alarm pressure switch and switching on and shutting down pressure switch.
Preferably, the utility model further includes having controller, which is arranged on the left of blower, the blower motor,
Servo motor, fire rod, alarm pressure switch, switching on and shutting down pressure switch are electrically connected with controller.
Preferably, filter described in the utility model is metallic filter.
Preferably, alarm pressure switch described in the utility model and booting pressure switch are externally provided with protective device, the protection
Device includes side wall and lid, and the side wall is disposed around outside alarm pressure switch and booting pressure switch, the lid shape with
Sidewall shape matches, and lid side is hinged with side wall, and the lid other side is mutually clamped with side wall.
Preferably, sealing ring is equipped in lid described in the utility model.
Preferably, lid described in the utility model is made of clear material.
Compared to the prior art the utility model have the characteristics that and the utility model has the advantages that
1, blower inner cavity is equipped with alarm pressure switch and switching on and shutting down pressure switch, by adding double pressure switches, has served as
When filter blocking is to the first stage, the preset pressure value of alarm pressure switch is reached, alarm pressure switch alarm reminds user clear
Wash filter.If user does not clean filter, when plugged filter is to second stage, the pre- of shutdown pressure switch is reached
If value, shutdown pressure switch is started to work, and forced stoppage, user has to clean filter, by the protection of double pressure switches,
Substantially increase the safety coefficient of burner.
2, the setting of protective device can effectively alarm pressure be switched and is switched on pressure switch and the external world separate, avoid its because
External world's collision or pollution and be damaged, while alarm pressure can be switched and be switched on pressure switch and blower inner cavity junction into
The sealing of one step avoids causing blower chamber pressure to change because its junction leaks.
Detailed description of the invention
