Abstract
The utility model discloses a kiln head cover for a rotary kiln. The kiln head cover is placed on a wheel (8) and comprises a lower cover (2) and an upper cover (3); an access door (6) is arranged on the lower cover (2); an instrument interface (4) is formed on the upper cover (3); a contact elastic sheet seal (5) is arranged between a rotary kiln cylinder and the kiln body cover; an ash outlet (7) is formed at the lower part of the lower cover (2) at a position adjacent to the tail end side of the cylinder; and a discharge port (9) of the kiln head cover deviates from the distance L relatively to the center line of the rotary kiln cylinder. An observation hole (10) is formed on the access door (6). An access door (1) is arranged at the discharge port (9) of the kiln head cover. The utility model provides a novel kin head cover device for the rotary kiln used in the chemical, cement, metallurgy and other engineering, which can improve the production efficiency, reduce heat loss, facilitate the manual operation and reduce the running cost.
Description
Technical field
The utility model relates to a kind of kiln hood closure assembly that is installed on the rotary kiln.
Background technology
In the engineerings such as chemical industry, cement and metallurgy, rotary kiln is the key equipment of integrated artistic.Often rotary kiln running stability is directly connected to the economic benefit of whole factory.The kiln hood cover is the important device on the rotary kiln, and it is installed between rotary kiln and the cooler blanking scraper-trough conveyer.The kiln hood cover is the mounting platform of main control instrument of rotary kiln and burner.Traditional kiln hood cover structure complexity is installed difficulty, and is had problems in the actual use.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of rotary kiln head-shield is provided, overcoming the kiln hood cover structure complexity that prior art exists, difficulty is installed, and have deficiency such as problems in the actual use.
The utility model is taked following technical scheme: the kiln hood cover is placed on the wheel, the kiln hood cover comprises cover and last cover down, following cover is provided with access door, on last the cover, instrumentation tap is set, contact flat spring sealing is set between cylinder of rotary kiln and kiln hood cover, under cover the bottom and be provided with ash hole near the barrel tip side; Kiln hood cover feed opening is with respect to cylinder of rotary kiln center line deviation distance L, 1/5～1/3 of L value and cylinder of rotary kiln diameter.
Peep hole is set on access door.
The place is provided with access door at kiln hood cover feed opening.
The utility model provides a kind of novel kiln hood closure assembly for the rotary kiln that uses in the engineerings such as chemical industry, cement and metallurgy, can enhance productivity, and reduces heat loss, makes things convenient for the workman to operate, and reduces operating cost.

Fig. 2 is structural representation of the present utility model, side view;
Fig. 3 is that A among Fig. 2 is to view.
The specific embodiment
Embodiment of the present utility model: constituent components of the present utility model is: access door 1, following cover 2, on cover 3, instrumentation tap 4, shell fragment sealing 5, access door 6, ash hole 7, wheel 8, feed opening 9, peep hole 10 etc.The kiln hood cover is placed on the wheel 8, the kiln hood cover comprises cover 2 and last cover 3 down, covers 2 down to be provided with access door 6, and instrumentation tap 4 is set on last cover 3, contact flat spring sealing 5 is set between cylinder of rotary kiln and kiln hood cover, under cover the bottom and be provided with ash hole 7 near the barrel tip side; Kiln hood cover feed opening 9 is with respect to cylinder of rotary kiln center line deviation distance L, 1/5～1/3 of L value and cylinder of rotary kiln diameter.
Peep hole 10 is set on access door 6.
9 places are provided with access door 1 at kiln hood cover feed opening.
Under cover 2 and be connected with last cover 3 usefulness bolts, form the main body of kiln hood over body case.Generally there are castable refractory or refractory brick to play the effect of protection housing in the housing.The central circular hole of housing is used for install combustion device burner.Instrumentation tap 4 is used for various sensors such as setting pressure and temperature, so that the normal operation of control rotary kiln.Rotatory sealing between cylinder of rotary kiln and the kiln hood cover realizes that with contact flat spring sealing 5 convection current with gas inside and outside the minimizing kiln influences the stable of rotary kiln thermal regulation.A small amount of material and dust can be discharged from ash hole 7.Maintenance and maintenance when access door 1 and access door 6 are used for equipment installation and rotary kiln running generally are provided with peep hole 10 on the access door 6.Wheel 8 can make the kiln hood cover move with respect to cylindrical shell, and breaks away from kiln cylinder body, and convenient the installation overhauled.Wheel 8 usefulness car bumpers were fixed when rotary kiln normally moved.
Kiln hood cover feed opening is with respect to cylinder of rotary kiln center line deviation distance L, and the distance of skew and direction are determined by the rotating speed and the rotation direction of rotary kiln.Normally in service at rotary kiln, material rotates under the drive at kiln cylinder body, must accumulate in the bottom, a left side (right side) of cylindrical shell, as shown in Figure 3.So offset distance L can better make material enter in the cooler cylindrical shell by cooler blanking scraper-trough conveyer smoothly, and has protected the kiln hood cover.
The place increases by an access door 1 at kiln hood cover feed opening.In rotary kiln running, bulk materials or idol have the bulk of peeling off to water material feeding often to be stuck in kiln hood cover feed opening place, hinder the material normal descend in cooler, increase access door 1, can be better with bulk materials or water material feeding and from access door 1, take out, offering convenience to workman's operation.
Claims (3)
1. rotary kiln head-shield, it is characterized in that: the kiln hood cover is placed on the wheel (8), the kiln hood cover comprises cover (2) and last cover (3) down, following cover (2) is provided with access door (6), instrumentation tap (4) is set on last cover (3), contact flat spring sealing (5) is set between cylinder of rotary kiln and kiln hood cover, is provided with ash hole (7) near the barrel tip side in following cover (2) bottom; Kiln hood cover feed opening (9) is with respect to cylinder of rotary kiln center line deviation distance L, and the L value is 1/5～1/3 of a cylinder of rotary kiln diameter.
