Description
Technical field
The utility model relates to a kind of fire tube boiler smoke pipe maintain and replace specific purpose tool, belongs to boiler service technique field, especially changes construction and specific purpose tool.
Background technology
Smoke pipe is the main heating surface of fire tube boiler, is positioned at drum, is welded on the tube sheet of front and back through the sagging plate play supporting role, and is the in a row tube bank be staggered in arrangement in column, the general hundreds of root of quantity.During boiler operatiopn, red-hot flue gas passes through at a high speed in pipe, the water outside heating tube.Due to washing away by flying dust in flue gas, the light pipe portion in smoke pipe porch easily forms ring-type pit, and then worn out leakage.And flue gas is maximum at middle part flow, flow velocity, so this part smoke pipe early start damages.
On smoke pipe external diameter and tube sheet, the design maximum gap of pore only has about 1mm, due to boiler longtime running, gap therebetween by the blocking such as incrustation scale, rust deposite, when changing smoke pipe, new pipe cannot in the past, in, pass in the pore of back tube sheet.Before and after tube sheet can to polish in the smoke box outside drum attachment, but be arranged in the tube sheet at middle part, distance front and back tube sheet often counts meter Yuan, and personnel cannot polish in distance so far away at all; Equally because distance, gap are little, smoke pipe also cannot align through.
Smoke pipe is once leak, just blowing out immediately must repair replacing, because the problem that on sagging plate, pore is polished several meters away and bored a hole cannot be solved, the method of current employing is dismantled damaging the smoke pipe do not damaged on smoke pipe top together, formation personnel can descend sagging plate to carry out the passage operated, and the good pipe torn open is often also more than the bad pipe that will change.Dismantle the last smoke pipe damaged except causing unnecessary damage to forward and backward tube sheet, because length shortens, cannot recycle, also must be replaced by new pipe, add investment and workload.Had the passage that personnel are upper and lower, workmen just can enter in narrow and small, moist drum, pore of polishing before sagging plate.Help centering at sagging plate place again after polishing is good, successively carry out smoke pipe installation from lower to upper by row.Narrow space, humidity in drum, there is larger security risk in temporary electricity, polishing in such restricted clearance, must take strict safety prevention measure, add input equally, reduce work efficiency.Because above-mentioned deficiency, so when damaging smoke pipe negligible amounts, generally take the interim measure of two ends shutoff, the smoke pipe after shutoff no longer participates in heat exchange, boiler output reduces.When damaging the smoke pipe quantity of shutoff and being more, larger on boiler output impact, just this part smoke pipe is changed.
In order to avoid above-mentioned two kinds of construction Problems existing, sometimes also take another interim measure, namely damage smoke pipe is extracted out certain length in drum, excised by damaged location, groovewelding connects one section of newly pipe.In order to the smoke pipe welded being resetted, also weld reinforcement to be polished flat, i.e. that section of local replacing smoke pipe damage.Due to the weld reinforcement without a booster action, weld seam is positioned at drum again, and specification does not allow.
Utility model content
The purpose of this utility model be overcome existing fire tube boiler smoke pipe maintain and replace difficulty, cost is high, efficiency is low, unsafe defect, provides a kind of fire tube boiler smoke pipe maintain and replace specific purpose tool.
The utility model comprises tube sheet sanding apparatus and seeker, and wherein: tube sheet sanding apparatus is made up of grinding head, extension bar and slowspeed machine, grinding head is welded on the front end of extension bar, and the end of extension bar is connected with motor; Seeker is umbrella-shaped structure, comprises conical head and is connected short circuit, and the diameter at the bottom of taper nose cone is consistent with the external diameter of smoke pipe to be replaced, connects the central through hole matched in clearance of short circuit and smoke pipe to be replaced.
The utility model can change the smoke pipe of damage in boilers quickly and efficiently, and cost is few, labour intensity is low, safety coefficient is high.
Accompanying drawing explanation
Fig. 1 is sagging plate of the present invention polishing schematic diagram;
Fig. 2 is the smoke pipe poling schematic diagram that seeker is housed of the present invention.
In figure: sagging plate 1, grinding head 2, extension bar 3, back tube sheet 4, square connector 5, universal joint 6, slowspeed machine 7, conical head 8, connection short circuit 9, anti-fall ring 10, pull rope 11, smoke pipe 12, front tube sheet 13.
Detailed description of the invention
Below in conjunction with accompanying drawing, concrete description is done to the present invention:
From Fig. 1 and Fig. 2, the utility model comprises tube sheet sanding apparatus and seeker, wherein:
Tube sheet sanding apparatus is made up of grinding head 2, extension bar 3, square connector 5 and slowspeed machine 7, and grinding head 2 is welded on the front end of extension bar 3, and square connector 5 is welded on the end of extension bar 3, is connected with slowspeed machine 7 by universal pipe nipple 6.
Seeker is umbrella-shaped structure, comprises conical head 8 and is connected short circuit 9, and the diameter that its conical head 8 bores the end is consistent with the external diameter of smoke pipe 12 to be replaced, and connecting short circuit 9 with the central through hole of smoke pipe 12 to be replaced is matched in clearance.
The tail end of described connection short circuit 9 is connected with pull rope 11 by anti-fall ring 10, can effectively prevent seeker from coming off from smoke pipe 12 to be replaced.
The file that described grinding head 2 is manual adjustable reamer or is uniformly distributed along the circumference.
When carrying out fire tube boiler smoke pipe maintain and replace, will damage after smoke pipe extracts out, manual adjustable reamer or the external diameter of file that is uniformly distributed along the circumference will be adjusted to sagging plate 1 pore intended diameter.
(A) sagging plate pore is cleared up:grinding head 2 penetrates from back tube sheet 4, enters sagging plate 1, slowspeed machine 7 is suspended on the position suitable with pore height of waiting to polish, connects extension bar 3 end and slowspeed machine 7 by universal joint 6, the pore switched on power on polishing sagging plate 1.
(B) poling:the pull rope 11 length being greater than smoke pipe 12 to be installed is fixed on the anti-fall ring 10 in seeker rear portion, and pull rope 11 is passed in smoke pipe 12, connects short circuit 9 and puts in smoke pipe 12, then pull rope is fixed at smoke pipe 12 end.The smoke pipe 12 front portion being equipped with seeker penetrates from back tube sheet 4, automatic capturing when seeker enters the pore on sagging plate 1, is flowed slowly over as helical rotation by smoke pipe during sagging plate 1 12, after smoke pipe 12 passes from front tube sheet 13, take off seeker, complete poling.
(C)repeat step (A) (B), until all smoke pipes have all been worn, then carry out expand tube and welding by operation.
