Abstract
The utility model discloses an air suction pipeline, which comprises a main pipeline, a plurality of rectangular air suction openings arranged on the main pipeline and a plurality of branch pipelines arranged at the air suction openings, wherein a connecting structure is arranged between the main pipeline and the branch pipelines; connection structure is including fixed the first connecting plate that sets up both sides about the suction opening, interval between first connecting plate and the suction opening is the wall thickness of lateral duct, the left and right sides of lateral duct is fixed respectively and is provided with the second connecting plate, the inboard of the at least tip at both ends about first connecting plate, the slot has been seted up on one of at least tip both ends about the second connecting plate, be provided with on another one of the two with slot matched with grafting portion, fix mutually through the fastener between slot and the grafting portion, not only intensity is high, non-deformable, and easy dismounting.
Description
Technical Field
The utility model relates to an exhaust pipeline.
Background
Air suction pipe among the prior art, as shown in fig. 1, it includes the trunk line, set up in a plurality of air suction openings that are the rectangle on the trunk line, install in a plurality of spinal branch pipelines of air suction opening department, and distribute in air suction opening bolt fastening all around through a plurality of between spinal branch pipeline and the trunk line, the port department of spinal branch pipeline still needs welded connection end plate in addition, the bolt will be connected the end plate and fix on the trunk line, the wall thickness of connecting the end plate at first is less, very easily produce the deformation when fixing its welded connection on the spinal branch pipeline, and will connect the end plate and need more bolt to be connected when fixing on the trunk line, cause and connect end plate multiple spot atress, cause air suction pipe to be at the during operation from this, cause the spinal branch pipeline multiple spot atress inhomogeneous, take place to warp easily and cause the damage phenomenon even.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the defect that exists among the prior art, provide an exhaust duct, not only intensity is high, non-deformable, easy dismounting moreover.
In order to achieve the above object, the technical scheme of the utility model provides an air suction pipeline is provided, include the trunk line, set up in a plurality of air suction openings that are the rectangle on the trunk line, install in a plurality of spinal branch pipes of air suction opening department, its characterized in that: a connecting structure is arranged between the main pipeline and the branch pipelines;
the connecting structure comprises first connecting plates fixedly arranged on the upper side and the lower side of the air suction opening, the distance between the first connecting plates and the air suction opening is the wall thickness of the branch pipe, second connecting plates are fixedly arranged on the left side and the right side of the branch pipe respectively, a slot is formed in one of the inner sides of at least one end part of the left end and the right end of the first connecting plate and at least one end part of the upper end and the lower end of the second connecting plate, an inserting part matched with the slot is formed in the other one of the inner sides and the lower end parts of the first connecting plate, and the slot and the inserting part are fixed through a fastener.
The further improvement is that: the first connecting plates are welded and fixed on the upper side and the lower side of the air suction opening.
The further improvement is that: the second connecting plates are welded and fixed on the left side and the right side of the branch pipeline.
The further improvement is that: the slots are formed in the inner sides of the left end and the right end of the first connecting plate, and the inserting portions are arranged at the upper end and the lower end of the second connecting plate.
The further improvement is that: the fastener is a bolt.
The further improvement is that: and a sealing gasket is arranged between the branch pipeline and the main pipeline.
The utility model has the advantages and the beneficial effects that: during the connection, the fastener is direct to be connected first connecting plate and second connecting plate, and the stress point of bolt does not directly act on trunk line and small transfer line, has significantly reduced the deformation of pipeline, and first connecting plate and second connecting plate both have reduced the use amount of bolt, easy dismounting through the cooperation of pegging graft in addition.
