Abstract
The utility model provides a sealing device for a kiln head of a rotary kiln, comprising an ash collecting hopper arranged at the kiln head and a sealing plate obliquely arranged between the ash collecting hopper and the kiln body. The sealing device is characterized in that a friction plate is arranged between the ash collecting hopper and the kiln body in circumferential direction; the sealing plate is arranged outside the friction plate; and a space formed by the sealing plate, the kiln body and the ash collecting hopper is filled with sealing filler. In the utility model, the space formed by the sealing plate, the kiln body and the ash collecting hopper is filled with the sealing filler, the friction plate with the T-shaped longitudinal section is arranged between the ash collecting hopper and the kiln body in circumferential direction, and an internal layer of sealing steel sheet adopts a welding steel ring structure; and simultaneously the internal layer of sealing steel sheet and an external layer of sealing steel sheet are fixed respectively by thick nuts and thin nuts; therefore, the sealing effect of the kiln head is greatly improved, the abrasion of the sealing steel sheet can be effectively reduced, the replacement frequency of the easily damaged parts can be reduced, the assembly and maintenance are convenient, and the connection is reliable and safe, thus being beneficial to prolonging the service life of the sealing device.
Description
Technical field
The utility model relates to a kind of rotary kiln end sealing device.
Background technology
The rotary kiln end sealing device is to the efficient operation of rotary kiln and stablize the thermal technology and play the very effect of key.In the normal course of operation of rotary kiln, because kiln hood is negative pressure state, it is not too obvious to leak grey phenomenon, and in case operate out of joint, then kiln hood leak ash will be very serious.
Existing Sealing of Rotary Kiln device is circumferentially tiltedly to establish plate sealing together to seal between flue-dust retainer that is arranged at kiln hood and kiln body.Though this hermetically-sealed construction is simple, sealing effectiveness is bad.
Summary of the invention
The purpose of this utility model is to provide a kind of rotary kiln end sealing device of good seal performance.
The purpose of this utility model is to realize like this, a kind of rotary kiln end sealing device, comprise that the flue-dust retainer that is arranged at kiln hood reaches the sealing plate that tiltedly is located between described flue-dust retainer and the kiln body, it is characterized in that: be circumferentially with friction plate between described flue-dust retainer and the kiln body, described sealing plate is arranged on the outside of described friction plate, fills up airtight and watertight padding in the space that described sealing plate and kiln body, flue-dust retainer form.
In order to strengthen sealing effectiveness, the longitudinal section of above-mentioned friction plate is the T type.
For easy for installation, above-mentioned friction plate is two semi-rings and connects by bolt.
In order to improve the sealing device functional reliability, above-mentioned sealing plate is made of intermediate seal plate, outer seal steel plate and internal layer seal steel plate.
In order further to improve the reliability of sealing device and to be convenient to install and maintenance, be provided with support below the above-mentioned flue-dust retainer, above-mentioned outer seal steel plate and internal layer seal steel plate are fixed on the described support by thickness nut and above-mentioned intermediate seal plate.
In order to be connected firmly, be provided with pressing plate between above-mentioned thickness nut and the described outer seal steel plate.
In order to alleviate wearing and tearing, above-mentioned internal layer seal steel plate is the weldable steel ring structure.
In order further to improve sealing effectiveness, the outside of above-mentioned sealing plate is provided with steel wire rope stretching device.
The utlity model has following beneficial effect, the utility model is at sealing plate, fill up airtight and watertight padding in the space that kiln body and flue-dust retainer form, and the friction plate that the longitudinal section is the T type is set circumferentially between flue-dust retainer and kiln body, the internal layer seal steel plate adopts the weldable steel ring structure, simultaneously, adopt the thickness nut fixing respectively to internal layer seal steel plate and outer seal steel plate, not only increased substantially sealing effectiveness, and can effectively reduce the wearing and tearing of seal steel plate, reduce the replacing frequency of consumable accessory, promptly be convenient to installation and maintenance, connect reliable and securely again, help prolonging life-span of sealing device.
