Description
Technical field
The present invention relates to a kind of risk explosion-proof air conditioners for building.
Background technique
Gunpowder, explosive, ammunition, fuse and its product risk building refer to development, processing, test, fractionation, destroy and deposit
Put the place of various gunpowder, explosive, ammunition, fuse and its product.This kind of risk building may produce in actual job
It lights a fire explosive dust or explosive gas, explosive wastewater and its dust have extremely strong destructiveness, are easy to produce subsequent explosion.Mesh
Before, the place that may generate explosive dust is substantially with the explosion-proof air conditioner suitable for explosive gas atmosphere
Substitution uses, have ignored explosive wastewater and its dust-ignition temperature and dust performance, existence, dust layer thickness and heat source
Geometry it is related, the electric arc of electric component (as switch, contact, rectifier, brush and like) or cremate, accumulation
Static discharge, mechanical spark relevant to electrical equipment, friction spark or waits factors, and very big safety is brought to Work places
Hidden danger.
Summary of the invention
The purpose of the present invention is to solve the above the deficiencies in the prior art, provide a kind of risk explosion-proof air for building
Adjusting machine, including adjusting air valve, fire arrester and the check-valves being connected in turn using air supply duct；The check-valves and resistance
Firearm passes through flanged joint；The adjusting air valve is connected on host；The air supply duct is connected with interior, air supply duct
It is interior to be equipped with back-flow preventer；The back-flow preventer includes cylindrical shell and sphere, and the upper end of the cylindrical shell passes through
Outlet plate is connected with the gas side that goes out of air supply duct, and the lower end of cylindrical shell is connected by ring flat-plate with the air inlet side of air supply duct；Institute
Several ventholes are uniformly distributed on the outlet plate stated；Conical cavity, the conical cavity are equipped with inside the cylindrical shell
Diameter be sequentially reduced from top to bottom, the sphere is located at the inside of conical cavity, and material is polyurethane；The anti-return
Wind page is equipped with before device outlet plate；Wind-guiding type blade-rotating is equipped with before the wind page；The wind-guiding type blade-rotating is mounted on air outlet.
Preferably, the check-valves is hermetic type check-valves.
Preferably, the host includes compression condensation unit and evaporation blowing unit.
Preferably, the fire arrester filter core is ripple type filter core.
Preferably, the air conditioner is mounted on outdoor.
The utility model has the advantages that
Air conditioner is mounted on outdoor by the present invention, prevents the factors such as the electric arc, mechanical spark, electrostatic of each electric component
Give Work places bring security risk；By back-flow preventer, fire arrester, check-valves etc., danger is prevented to be back to sky
Controlled atmosphere section machine, removes a hidden danger.

It is connected with interior, air supply duct is equipped with back-flow preventer；The back-flow preventer includes cylindrical shell 4 and sphere 5, described
The upper end of cylindrical shell 4 is connected by outlet plate 9 with the gas side that goes out of air supply duct, and the lower end of cylindrical shell 4 passes through ring flat-plate and send
The air inlet side of air piping is connected；Several ventholes 8 are uniformly distributed on the outlet plate 9；It is set inside the cylindrical shell 4
There is conical cavity, the diameter of the conical cavity is sequentially reduced from top to bottom, and the sphere 5 is located at the inside of conical cavity；
Wind page 6 is equipped with before the back-flow preventer outlet plate 9；Wind-guiding type blade-rotating 7 is equipped with before the wind page 6；The wind-guiding type
Blade-rotating 7 is mounted on air outlet.
The check-valves is closed check-valves.
The host includes compression condensation unit and evaporation blowing unit.
The air conditioner is mounted on outdoor.
The fire arrester filter core is ripple type filter core.
Working condition:
1, risk building is flowed to through air supply duct through the air in the processed safety zone of air conditioner.
2, air supply duct has check-valves and back-flow preventer, and danger is prevented to be back to air conditioner, removes a hidden danger.
3, when explosive flame pours into air supply duct, flame is completely cut off by fire arrester, prevents from entering air conditioner.
