Description
Technical field
The invention belongs to grate kiln production technology field, especially relate to a kind of deashing device for grate kiln hot air duct.
Background technology
In grate-kiln pelletizing process production technology, thermal engineering pipeline occupies critical role in whole pelletizing process.The unimpeded of thermal engineering pipeline is one of necessary condition ensureing pellet roasting quality.Grate-kiln pelletizing process technological design thermal technology principle is: be evenly arranged iron charge ball on grate plate top, and at drying grate cloth grate plate bottom symmetric arrays bellows, bellows are connected with hot blast manifold respectively, and many group hot blast manifolds are connected with main pipeline.When the even cloth of iron charge ball is in grate plate, with grate plate double symmetry organize more bellows move time, by the effect of bellows hot air flow, reach the object of solidification iron charge ball.
In production real process, Problems existing is: when in the grate plate that iron charge ball is in motion with in its motion process, by the moisture of iron charge ball own, temperature, vibrations, the factor cause influence such as distinguished and admirable, the iron charge ball and the broken end that have part explosion fall into the bellows of bottom and the hot blast manifold of hot air duct by motion grate plate, cause iron charge thing in hot blast manifold to pile up.There will be indivedual hot blast manifold time serious and blocked situation.When occurring in indivedual hot blast manifold that iron charge ball and broken end are piled up, the thermal technology of system balances destroyed.Cause iron charge ball can not be cured by production engineering specifications on grate plate.Whole system hot air flow balance is broken simultaneously, distinguished and admirable flow velocity in part hot blast manifold can be caused to accelerate, heat energy transmits uneven, and the iron charge ball that the meeting that flow velocity is large dispels in grate plate burns out grate plate, and the meeting that flow velocity is little causes the iron charge ball in grate plate not complete production engineering specifications.Larger impact is had on product quality.The positive and negative pressure state being in elevated-temperature seal due to system is run, and when occurring having deposit or indivedual hot blast manifold to be blocked in thermal engineering pipeline, processes when necessarily waiting until stop production to overhaul.The processing method generally adopted now is: by maintainer after stop production to overhaul tube-cooled to normal temperature, enter in thermal engineering pipeline and check, to there being the pipeline section of deposit to dismantle in pipeline, re-assembly after labor cleaning, or operating personnel directly clears up in sleeping in-line portion of climbing.Carrying out dismounting cleaning not only causes the repair time long, and costly, environmental pollution is large, and process in artificial nest, and working space is little, bad environments, and labour intensity is large, and operating personnel is operation in pipeline, very big to the health hazards of operating personnel.
Summary of the invention
The object of this invention is to provide a kind of structure simple, deashing device for grate kiln hot air duct easy to use, existing technological design can be solved online and occur the problem that individual tubes is blocked by pellet or breeze in process of production, guarantee thermal engineering pipeline is unimpeded, the thermal efficiency of raising system, reduces system energy consumption.

Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
The specific embodiment of the present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, deashing device for grate kiln hot air duct of the present invention, it is characterized in that comprising the injection tube 8 vertically penetrating and be arranged on hot air duct 7 tube wall, be fixedly connected on the air positioning disk 6 that this injection tube 8 is positioned at the inner termination inside hot air duct 7, the air that the inner termination of injection tube 8 socket-connects therewith divides to pipe 5, be located at this air to divide to pipe 5 inside and the block-resistant protection blast cap control lever 2 be slidably connected with it, the block-resistant protection blast cap 4 that is fixedly connected with of termination, block-resistant protection blast cap control lever 2 top therewith, be located at described air and divide block-resistant protection blast cap return spring 1 to pipe 5 inside, be located at the air valve 9 on tube wall that described injection tube 8 is positioned at outside hot air duct 7, the air valve controller 10 that is connected of air valve 9 therewith, the compressed-air line 11 be connected with described air valve 9, described block-resistant protection blast cap return spring 1 is connected with the termination, bottom of described block-resistant protection blast cap control lever 2, described air divides the top to pipe 5 to be provided with one group of air and divides to hole 3.
It is the strip hole longitudinally arranged that described air divides to hole 3.
The guide angle α of described air positioning disk 6 is 0 degree of-60 degree.
Described injection tube 8 diameter is 20 millimeters-40 millimeters.
