During in heeling condition, it still can be used, improve the flexibility and safety during use.
During alkali recovery boiler deashing, blowing out for a period of time, is cooled to after personnel can enter after boiler, opens alkali collection pot
Stove manhole 24 is removed after 24 periphery of manhole and furnace interior divide dust stratification, and personnel enter in alkali recovery boiler, the shade screen that will wind up from
Manhole 24 is passed in alkali recovery boiler, and the rope 3 being connect with 2 one end of screen body is tied on furnace outlet boiler tubing 1, shields body 2
After expansion, the other end arrives at dust stratification layer surface；It is artificial remove at the top of alkali recovery boiler furnace outlet and the dust stratification of side wall attachment and
After dust stratification layer surface dust stratification easy to fall off, boring device is passed from manhole 24 in alkali recovery boiler, by external hydraulic oil pipe and cold
But liquid pipe is led through manhole 24 or alkali recovery boiler operation hole in alkali recovery boiler, by the hydraulic motor 4 of boring device and outside
Hydraulic oil pipe connection, by the coolant inlet tube of boring device（22）With coolant outlet tube（23）With external coolant pipe
Connection, by the cutting tool of boring device（7）Dust stratification layer surface is moved to, manipulates boring device, is cut in dust stratification layer surface several
Blind hole, adjacent blind hole intersect or close to each other；Drill steel is hammered into shape from manhole 24 and is passed in alkali recovery boiler, by external power supply pipeline
Led in alkali recovery boiler through manhole 24 or alkali recovery boiler operation hole, by drill steel hammer push rod, cylinder or hydraulic cylinder 16 with
The drill rod 18 that drill steel is hammered into shape is moved to by the blind hole that boring device is cut into, manipulates drill steel by the connection of externally input power source pipeline
Hammer, a part for drill rod 18 is impacted in dust stratification layer, hand steered operating lever 19 agitates drill rod 18, and dust stratification is made to come off, the product to come off
Grey block is outside the removal stove of manhole 24 or after broken through being fallen into ash bucket at alkali recovery boiler tube bank；It repeats to make after clearing up a lamination ash
Drill rod is made with boring device trepanning, using drill steel hammering, agitates drill rod operation, is cleaned out until by dust stratification.
In the prior art, personnel is needed to enter stove because part dust stratification falls into burner hearth bottom in the dust stratification for removing furnace outlet
Thorax bottom is raked off at alkali recovery boiler chute, otherwise can influence the normal boot-strap of alkali recovery boiler, extend the deashing time and
Increase labor intensity.Shade screen is mounted on furnace outlet boiler tubing 1, in deashing process, dust stratification can be prevented to fall into burner hearth
It is interior, the dust stratification of burner hearth bottom is fallen into without entering back into cleaning in stove；Shade screen can also prevent furnace outlet hot gas and
Dust is directly entered personnel operation area, improves operating environment；Improve the safety of operation.With boring device by dust stratification layer from level to level
Ground is cut into blind hole, and the dust stratification on blind hole periphery is made easily to be agitated and is come off, and then falls dust stratification local near dust stratification in sled
It is easily agitated and is come off.The dust stratification characteristic of alkali recovery boiler is influenced by factors such as combustion conditions, run time, dust stratification positions, no
Very big with the dust stratification property difference at operating condition and different location, some hard such as rock, some such as quicksands use common impact gun
During machine operation, although the drill steel of air inflating machine for dismantling tyre can be rapidly entered in dust stratification layer in most cases, performance and work because of air inflating machine for dismantling tyre
Principle is only capable of getting a hole, agitates loose around Shi Yinkong, it is impossible to agitate the dust stratification of bulk, working efficiency is extremely low.And people
Work is impacted drill rod in dust stratification layer using weight, and impact mode can make dust stratification layer cracking bulk come off.Drill steel hammer simulates
The method of manual work impacts drill rod 18 using weight, can obtain and artificial deashing similar in technique effect, with higher work
Industry efficiency, and reduce labor intensity.
Temperature inside blowing out for a period of time inner product grieshoch is still higher, and hundreds of degree are sometime up to inside dust stratification layer（It is internal
Dust stratification is rubescent, and spontaneous radiation has reached the longest wave band in visible ray）, during using boring device trepanning, pass through coolant pair
Rotary shaft 6 and cutting tool 7 are cooled down, and are conducive to keep the performance of cutting tool 7, are prevented from wearing too quickly at high temperature.
