Description

Telescopic smoke exhaust pipeline system with smoking arms

Technical Field

The utility model relates to a smoke exhaust pipe field, concretely relates to retractable smoking arm exhaust pipe system.

Background

Due to the special requirements of the smelting furnace, mainly temperature control is adopted, a dust hood is required to be used for plugging in a non-dust-removing state, when dust is required to be removed, dust removing equipment is butted with a dust removing pipeline of a furnace body, at present, flexible pipelines are mostly adopted, however, the flexible pipelines are difficult to bear the dust removing temperature, the service life of the flexible pipelines is short, and the flexible pipelines are difficult to adapt to the complex working conditions.

In view of the problems existing in the prior art, the utility model discloses combine many years' design and experience of use in relevant field, assist too strong professional knowledge, designed and manufactured a retractable smoking arm exhaust pipe system, overcome above-mentioned defect.

SUMMERY OF THE UTILITY MODEL

To the problem that exists among the prior art, the utility model provides a retractable smoking arm exhaust pipe system can realize exhaust pipe's good butt joint to can improve its life-span.

In order to realize the purpose, the utility model discloses a technical scheme as follows: a telescopic smoke exhaust pipe system with a smoke exhaust arm comprises a base, wherein an oil cylinder is hinged to the base, and the other end of the oil cylinder is connected with a smoke exhaust cover;

the outer arm, outer arm one end side is connected with the smoke absorption cover, the inner arm has been inlayed to outer arm other end cover, the inner arm other end is equipped with adjustable fixing device, the inner arm can be relative adjustable fixing device rotates.

As a preferable technical scheme, a plurality of reinforcing plates are arranged on the outer side of the outer arm.

As a preferable technical scheme, a positioning baffle is arranged on the outer side of the inner arm, and the positioning baffle can position the limit position of the outer arm extending into the inner arm.

Preferably, the cross sections of the outer arm and the inner arm are rectangular.

As a preferred technical scheme, a plurality of wear-resistant guide plates are arranged on the inner side of the outer arm, and the wear-resistant guide plates are arranged at four corners of the inner side of the outer arm.

The utility model discloses an useful part lies in:

1. the utility model discloses a rotatable scalable smoking arm structure has realized exhaust pipe's good butt joint, has both guaranteed to remove dust and has guaranteed the furnace temperature.

2. Through the reinforcing plate, the structural strength of the outer arm opening is guaranteed, and the stability and the sealing performance of the outer arm and the inner arm during relative movement are further improved.

3. The utility model discloses the guiding orientation of inner arm and outer arm is realized through wear-resisting deflector, has and bears the weight of the height and can bear intermittent type and the motion of swaing, need not to refuel in the use and maintain, and assembly, debugging convenience (traditional guiding axle direction occupation space just need often add the lubricating oil lubrication).

Drawings

FIG. 1 is a view of a telescopic smoke exhaust duct system;

FIG. 2 is a partial block diagram of the inner and outer arms of a telescoping smoking arm smoke exhaust duct system.

In the figure: 1-base, 2-oil cylinder, 3-smoke absorbing hood, 4-outer arm, 5-inner arm, 6-reinforcing plate, 7-positioning baffle, 8-adjustable fixing device and 9-wear-resistant guide plate.

Detailed Description

In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, a telescopic smoke exhaust pipe system with a smoke exhaust arm comprises a base 1, wherein an oil cylinder 2 is hinged on the base 1, and the other end of the oil cylinder 2 is connected with a smoke exhaust hood 3; still include

outer arm

4, 4 one end sides of outer arm are connected with smoke absorption cover 3, and outer arm 4 and smoke absorption cover 3 are coaxial, and the other end cover of outer arm 4 has inlayed inner arm 5, and the 5 other ends of inner arm are equipped with adjustable fixing device 8, and inner arm 5 is adjustable fixing device 8 relatively and rotates, and at the butt joint in-process, inner arm 5 stretches out for outer arm 4.

The utility model discloses the 4 outsides of outer arm are equipped with a plurality of reinforcing plates 6, and this structure has guaranteed the structural strength of 4 arm mouths of outer arm, stability and leakproofness when further having improved outer arm 4 and inner arm 5 relative activity, the utility model discloses the 5 outsides of inner arm are equipped with positioning baffle 7, and positioning baffle 7 accessible restriction reinforcing plate 6's position location outer arm 4 stretches into the extreme position of inner arm 5.

The utility model discloses the preferred rectangle in 5 cross-sections of outer arm 4 and inner arm, the 4 inboards of outer arm are equipped with a plurality of wear-resisting deflector 9, and wear-resisting deflector 9 sets up in 4 inboard four angle departments of outer arm, has and bears the weight of highly and can bear intermittent type and the motion of swaying, need not to refuel in the use and maintains, and assembly, debugging convenience (and traditional guiding axle direction occupation space just need often add the lubricating oil lubrication).

It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes, modifications and/or alterations to the present invention may be made by those skilled in the art after reading the technical disclosure of the present invention, and all such equivalents may fall within the scope of the present invention as defined by the appended claims.
