Abstract
A kind of purification fan with groove clamp-type air duct port, including hexahedron shell, purification air duct and centrifugal blower, it is characterized in that, the air inlet and air outlet for purifying the both ends in air duct are located at hexahedron shell opposite face: the air inlet and air outlet external clamp-type air duct port, it is fixedly connected on shell, clamp-type air duct port outer rim is equipped with groove, and clamp-type air duct port aperture is designed using reduced pipe, and clamp-type air duct port is connect with extension pipeline using groove pipe fitting.It only needs to fix on the port of air duct when external pipe is installed in this way, it is simple and convenient.Not only the problem of having can solve blower purification air duct leakproofness differential loss bad blower, but also centrifugal blower can be protected to run well, extend the service life of blower.
Description
Technical field
The present invention relates to a kind of air cleaning units, and in particular to a kind of purification wind with groove clamp-type air duct port
Machine.
Background technique
Pipeline groove interconnection technique is risen in the U.S. of the 1950s, introduces China the end of the nineties.Hereafter, with its peace
Fill convenient, reliable in quality, it is economic and environment-friendly outstanding advantages of, received and promoted by domestic market rapidly.In national legislation policy
A clear guidance under, the technology is widely used to fire water-supply, domestic water, central air-conditioning, sewage treatment, petroleum at present
The multiple fields such as work, thermoelectricity and military project, and gradually replace flange and weld both traditional pipeline connection types, become gas,
The first-elected technology of liquid pipe road connection.
Existing new blower ventilation shaft is both tradition using flange and welding with the connection type of extension pipeline
Pipeline connection type is there are poor sealing performance, noise also larger problem when fan operation.It is more serious to the loss of blower simultaneously,
The service life of blower greatly reduces.
Summary of the invention
The technical problem to be solved by the present invention is to overcome drawbacks described above of the existing technology, provide a kind of purification wind
Road good airproof performance, the purification fan with groove clamp-type air duct port of fan operation low noise.
The technical solution adopted by the present invention to solve the technical problems is as follows: a kind of with groove clamp-type air duct port
The centre of purification fan, including hexahedron shell, purification air duct 9 and centrifugal blower 5, the purification air duct 9 is equipped with filter screen 4,
The air inlet 3 and air outlet 6 for purifying the both ends in air duct 9 are located at hexahedron shell opposite face: air inlet 3 and air outlet 6 are outer respectively
It is connected to clamp-type air duct port, is fixedly connected on hexahedron shell, the clamp-type air duct port outer rim of air inlet 3 is equipped with air inlet
The clamp-type air duct port aperture of oral groove slot 302, air inlet 3 is designed using reduced pipe, including air inlet mouth width diameter hole 301 and air inlet
The clamp-type air duct port in the narrow diameter hole 303 of mouth, air inlet is connect with extension pipeline using groove pipe fitting；Clamp-type air duct end
It is fixed when port clamp-type air duct port is connect with extension pipeline using groove pipe fitting equipped with clip；The clamp-type air duct
Port, which passes through bolt or is welded and fixed, to be connected on hexahedron shell.
Further, the clamp-type air duct port of air inlet 3 is bolted to connection on shell communicates with air outlet 6；
The clamp-type air duct port of air outlet 6 is arranged with the clamp-type air duct port of air inlet 2.
Further, local intake stack 1 and local wind pipe 8 are flexible duct.
Air inlet and air outlet are connect behaviour by groove pipe fitting with external pipe due to clamp-type air duct port by the present invention
Make simple, required operating space becomes smaller, and brings for maintenance in the future and many facilitates condition.When pipeline needs repairing and more
When changing, only need to unclamp two panels clip can arbitrarily replace, rotate, modifying a Duan Guanlu.It is thus not required to destroy surrounding wall, subtract
Maintenance time and maintenance cost are lacked.
The invention has the advantages that: there are unique flexibility characteristics with clamp-type air duct port, make to purify air duct and extension
Pipeline closely connects, good integrity, has anti-vibration, anti-shrink and the ability of expansion, compared with welding with flanged joint, ventilation
The leakproofness and stability of pipe-line system are more preferable, and are more suitable for the variation of temperature, so that blower be protected to operate normally, increase blower
Service life, decrease destruction of the ventilation shaft stress to structural member.

Embodiment
The present embodiment have groove clamp-type air duct port purification fan, including hexahedron shell, purification air duct 9 and from
The centre of heart blower 5, purification air duct 9 is equipped with filter screen 4, and the air inlet 3 and air outlet 6 for purifying the both ends in air duct 9 are located at six faces
Body shell body opposite face: air inlet 3 and air outlet 6 are circumscribed with clamp-type air duct port respectively, are fixedly connected on hexahedron shell,
The clamp-type air duct port outer rim of air inlet 3 is equipped with air inlet groove 302, and the clamp-type air duct port aperture of air inlet 3 uses
Reduced pipe design, including air inlet mouth width diameter hole 301 and the narrow diameter hole 303 of air inlet, the clamp-type air duct port of air inlet and extension
Pipeline is connected using groove pipe fitting；The clamp-type air duct port of air inlet 3 is bolted to connection on shell and air outlet 6
It communicates；The clamp-type air duct port of air outlet 6 is arranged with the clamp-type air duct port of air inlet 2, local intake stack 1 and part
Wind pipe 8 is flexible duct.
