The utility model discloses an increase the counter weight ring on the telescopic joint outer lane, guarantee its rigidity and toughness demand, realize the telescopic joint freely flexible distortion not appearing removing the in-process, prevent that the telescopic joint pipeline from blockking up, guarantee the air volume and the effect of gathering dust, satisfy negative pressure ventilation operation requirement, improved equipment reliability, simple structure, the effect is obvious, economical and practical, safety ring protects.
Description
Technical Field
The utility model relates to a dust collector for mud bag workshop, specifically a dust collector import telescoping device.
Background
The dust collector system for the loading lane of the cement bagged workshop, which ensures that no dust occurs in the loading link by virtue of a dust collector in the production process, has different heights and shapes of vehicles, increases a dust collector inlet expansion device for ensuring the dust collecting effect, extends or compresses the end part along with the adjustment of the loading height, installs a common dust collector negative pressure expansion joint in the initial stage, and has a larger swing amount in the operation process, which can reach 70-80 cm at most, when the expansion joint has the swing condition and finishes the expansion operation, the expansion joint is distorted and deformed, and blocks a pipeline, so that the ventilation volume is reduced, the dust collecting effect is reduced, and the dust is caused to occur, thereby having great influence on the vehicles, personnel and the whole environment.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem to provide a dust collector import telescoping device that can prevent distortion, pipeline jam, guarantee air volume and dust collection effect.
The utility model provides a problem, the technical scheme who adopts is:
the utility model provides a dust collector import telescoping device, includes tuber pipe, telescopic joint, the dust cage of gathering dust, the upper end and the lower extreme of telescopic joint are connected through double-deck staple bolt and tuber pipe and dust cage of gathering dust respectively, and the interval is provided with a plurality of sleeves from top to bottom on the outer lane of telescopic joint, is provided with the counter weight ring in the sleeve.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:
① the counterweight ring is added on the outer ring of the telescopic joint to meet the requirements of rigidity and toughness, the telescopic joint can freely stretch without distortion in the moving process, the pipeline of the telescopic joint is prevented from being blocked, the ventilation quantity and dust collection effect are ensured, the use requirement of negative pressure ventilation is met, and the reliability of equipment is improved.
② has simple structure, obvious effect, economy, practicality, safety and environmental protection.
Preferably, the present invention further provides:
the telescopic joint is telescopic canvas, and the sleeve is the canvas cover with telescopic canvas structure as an organic whole, and counter weight ring suit is in the canvas cover, and telescopic joint and sleeve adopt the canvas to make an organic whole structure, and the structure is simpler, and preparation and equipment are more convenient.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is an enlarged view of a portion of the section A-A in FIG. 1;
in the figure: a dust collection air pipe 1; an expansion joint 2; a dust collection cover 3; a sleeve 4; a counterweight ring 5.
The specific implementation mode is as follows:
the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.
Referring to fig. 1 and 2, the dust collector inlet expansion device comprises a dust collection air pipe 1, an expansion joint 2 and a dust collection cover 3, wherein the upper end and the lower end of the expansion joint 2 are respectively connected with the dust collection air pipe 1 and the dust collection cover 3 through double-layer hoops, a plurality of sleeves 4 are arranged on the outer ring of the expansion joint 2 at intervals from top to bottom, and counterweight rings 5 are arranged in the sleeves 4.
The utility model discloses owing to increase counter weight ring 5 on the 2 outer lanes of telescopic joint, under the influence of gravity, realize telescopic joint 2 and freely stretch out and draw back the disappearance distortion in the removal in-process, prevent that 2 pipelines of telescopic joint from blockking up, guarantee the air volume and the effect of gathering dust, satisfy negative pressure ventilation operation requirement, improved equipment reliability, simple structure, the effect is obvious, economical and practical, safety ring protects.
The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.
