The utility model provides a technical scheme that above-mentioned technical problem adopted does: a kiln head cover of a rotary kiln is characterized in that: comprises a main body, a main ash bucket, a flange ring, a discharging pipe, an auxiliary ash bucket and a flexible sealing plate; the main ash bucket is arranged below the main body, an opening at the upper end of the main ash bucket is inserted and fixed on the lower side end face of the main body and is communicated with the inside of the main body, the flange ring is vertically and concentrically fixed on the lower side end face of the main body and is arranged at the inner side of the main ash bucket, a plurality of auxiliary ash buckets distributed annularly are fixed on the inner wall of the flange ring, a discharging pipe is arranged between the opening at the lower end of each auxiliary ash bucket and the main ash bucket, the upper end of each discharging pipe is connected to an opening at the lower end of each auxiliary ash bucket, the lower ends of the discharging pipes are inserted and fixed on the side face of the main ash bucket and are communicated with the inside of the main ash bucket, and a flexible sealing plate is fixed outside the inner side of each auxiliary ash bucket.

Preferably, a plurality of concentrically arranged material blocking rings with different inner diameters are further fixed at the bottom of the inner part of the main body.

Preferably, wind deflectors which are transversely distributed are further fixed inside the main ash bucket.

Compared with the prior art, the utility model has the advantages of: the utility model greatly improves the sealing effect to avoid ash leakage and air leakage, thereby preventing the environmental pollution of the factory and greatly reducing the cleaning workload of the kiln head, simultaneously preventing the temperature reduction of secondary air and tertiary air, and ensuring the coal feeding amount of the kiln head and the stability of the system; in addition, the material ash between the connecting position of the kiln head cover and the rotary kiln can be automatically guided away, and the operation is time-saving and labor-saving.

Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and components may be omitted.

As shown in fig. 1-2, a kiln head cover of a rotary kiln comprises a main body 8, a main ash bucket 3, a flange ring 9, a blanking pipe 4, an auxiliary ash bucket 5 and a flexible sealing plate 6; main ash bucket 3 locates the below of main part 8, the upper end opening part of main ash bucket 3 inserts to be fixed on the downside terminal surface of main part 8 and communicates each other with the inside of main part 8, flange ring 9 is vertical and fixes on the downside terminal surface of main part 8 with one heart and locates the inboard of main ash bucket 3, be fixed with a plurality of hoop distribution's vice ash bucket 5 on the inner wall of flange ring 9, all be equipped with a unloading pipe 4 between the lower extreme opening part of every vice ash bucket 5 and main ash bucket 3, the lower extreme opening part at vice ash bucket 5 is connected to the upper end of unloading pipe 4, the lower extreme of unloading pipe 4 inserts to be fixed in the side of main ash bucket 3 and communicates each other with the inside of main ash bucket 3, the inboard outside of every vice ash bucket 5 all is fixed with a flexible sealing board 6.

The inside bottom of main part 8 still is fixed with a plurality of concentric settings and the internal diameter diverse keeps off material ring 1, and the inside of main ash bucket 3 still is fixed with transversely distributed's deep bead 2.

When in use: the end part of each flexible sealing plate 6 is upwards attached to the lower side end surface of a sealing sleeve 7 arranged below the rotary kiln 10 by utilizing the elasticity of the flexible sealing plate; a lower opening of the main ash hopper 3 is connected with a blanking scraper-trough conveyer to guide away the collected fly ash; when the rotary kiln 10 is operated, if fly ash runs to the lower end face of the main body 8, the fly ash is firstly blocked by the plurality of material blocking rings 1, the fly ash blocked above the main ash hopper 3 by the plurality of material blocking rings 1 falls into the main ash hopper 3 and is collected and guided away by the discharging chute, and the wind shield 2 can prevent the captured fly ash from rising due to airflow, so that secondary flying dust is prevented from escaping; the fly ash blocked by the material blocking rings 1 at the inner side of the opening at the upper end of the main ash hopper 3 can slide into the auxiliary ash hoppers 5, and then is guided into the main ash hopper 3 through the discharging pipe 4, and finally is collected and guided away through the discharging scraper-trough conveyer after being mixed with the fly ash in the main ash hopper 3.

After stopping and shunting of a plurality of material rings 1, most escape flying ashes have been collected, and remaining trace flying ashes can escape to the below of sealing sleeve 7, nevertheless can be blockked and can not reveal to the outside by a plurality of flexible sealing plate 6 to in following flexible sealing plate 6 equal landing to vice ash bucket 5, also entering into main ash bucket 3 inside according to the same principle at last.

The utility model greatly improves the sealing effect to avoid ash leakage and air leakage, thereby preventing the environmental pollution of the factory and greatly reducing the cleaning workload of the kiln head, simultaneously preventing the temperature reduction of secondary air and tertiary air, and ensuring the coal feeding amount of the kiln head and the stability of the system; in addition, the material ash between the connecting position of the kiln head cover and the rotary kiln can be automatically guided away, and the operation is time-saving and labor-saving.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
