Described curved entire body 3 is made up of curved logical body 6, attachment flange 7, packing seal 8, seal cover cap 9, binding bolt group 10, along having square opening on curved logical body 6 extrados 12, the square opening periphery is fixed with attachment flange 7, seal cover cap 9 is pressed on the packing seal 8, be fixed on by bolt of rear end plate group 10 on the attachment flange 7 of curved logical body 6, form the closed channel 11 of gas delivery;
Described pipeline reducing 2,4 is connected and composed by pipe transfer line 14 and hemispherical dome reducing 15 two parts;
All adopt Type of Welding fixing as a whole between described curved entire body 3, hemispherical dome reducing 15, pipe transfer line 14, the pipeline connecting flange, finish the function that material pneumatic or dust-contained airflow are altered course and carry jointly;
Described pipeline connecting flange 1,5 adopts nonstandard dust suction and strength transfer line butt flange;
The cross section of described curved logical body 6 is square for ease of processing;
Curved logical body 6 adopts the large radius arc forms, wholely constitutes one section cavity ring 13, and more than six times of the desirable pipeline diameter of center arc radius guarantee that transported substance materials flow or dust-contained airflow can slick and sly changed course transition;
The curved logical steering angle of described changed course can adopt different angles according to practical application, to satisfy need of work.
This structure of the present utility model, the curved logical existence of common changed course that has solved pipeline changed course position employing is stopped up and the two big drawbacks of wearing and tearing, prevent curved logical the obstruction thereby reached, the problem that easy access is changed, simultaneously, reduce the replacement cost of worn parts, reduced the work capacity of plant maintenance, alleviated the labour intensity of service personnel.

The specific embodiment
Below cooperate specific embodiment, further set forth structure design of the present utility model and technology.Should be understood that following embodiment only to be used to the utility model is described and be not used in the scope of the present utility model that limits.
The dust suction of present embodiment and the curved exchange device of strength transfer line changed course are with reference to Fig. 1-9, comprise curved entire body 3, curved entire body 3 two ends are respectively equipped with the pipeline reducing 2 of hemispherical dome, 4, curved entire body 3 is by pipeline reducing 2,4 respectively with pipeline connecting flange 1,5 are connected, curved entire body 3 is by curved logical body 6, attachment flange 7, packing seal 8, seal cover cap 9, binding bolt group 10 is formed, along having square opening on curved logical body 6 extrados 12, the square opening periphery is welded with attachment flange 7, seal cover cap 9 is pressed on the packing seal 8, be fixed on by bolt of rear end plate group 10 on the attachment flange 7 of curved logical body 6, form the closed channel 11 of gas delivery; Pipeline reducing 2,4 is connected and composed by pipe transfer line 14 and hemispherical dome reducing 15 two parts; All adopt Type of Welding fixing as a whole between curved entire body 3, pipe transfer line 14, hemispherical dome reducing 15, the pipeline connecting flange 1,5, finish the function that material pneumatic or dust-contained airflow are altered course and carry jointly; Pipeline connecting flange 1,5 adopts nonstandard dust suction and strength transfer line butt flange, the cross section of curved logical body 6 is square for ease of processing, curved logical body 6 adopts the large radius arc form, one section cavity ring 13 of whole formation, more than six times of the desirable pipeline diameter of center arc radius, guarantee that transported substance materials flow or dust-contained airflow can slick and sly changed course transition, the curved logical steering angle of changed course can adopt different angles according to practical application, to satisfy need of work.
When delivery air enters the pipeline reducing 4 that links to each other with pipeline connecting flange 5 along pipeline in, by pipeline reducing 4 delivery air is imported curved entire body inner sealing passage 11, because the large radius arc structure of curved logical body 6, guaranteed that delivery air obtains rounding off changed course and do not produce latch up phenomenon, delivery air after the changed course enters the transfer line of the other end by pipeline reducing 2 and pipeline connecting flange 1, realizes the smooth changed course of delivery air.
Compared with the prior art the utility model has the following advantages:
Curved logical body 6 adopts the large radius arc structure to guarantee the slick and sly changed course of delivery air and does not produce latch up phenomenon, because curved logical body 6 extrados 12 are to bear delivery air to impact maximum position, is the curved exchange device position the most easy to wear that alters course.Therefore, on curved logical body extrados 12, have square opening 13, and seal, both guaranteed the single-piece closure, guarantee again after wearing and tearing, can be convenient for changing, avoided integral replacing simultaneously, reduced replacement cost with seal cover cap and packing seal along extrados.
