Be attached to tar, carbon black on the bell, need to remove with bell clearing apparatus (common name " door swabbing pig ").The place that must remove, with reference to Figure 12, be be installed in bell body (door-plate) 2 fronts of bell 1 and divide the steel plate 3 of gas passage 7 full peripheral part, be installed in the fore-end (with the contact part of the stove frame 6 that constitutes coke stove peristome) of the knife-edge support 4 on these steel plate 3 outward flanges, the two sides that are installed in the lagging material that slightly is the square column shape 5 of steel plate 3 fronts, bottom surface and above, but bell clearing apparatus in the past, generally the full circumferential portion to steel plate 3 has adopted the scraper plate mode, and lagging material 5 is adopted the rotary cutting mode.But, can not be attached to the tar of knife-edge support 4 fore-ends, the removing of carbon black.
But above-mentioned bell clearing apparatus in the past has following problem:
(1) steel plate 3 is very thin, and with the scraper plate mode of mechanical contact, steel plate 3 sustains damage easily.
(2) overlapping of the core of bell 1 and bell clearing apparatus, all around direction does not all have more than neededly, so scraper plate is difficult to closely contact with the dirt settling cleaning face of steel plate 3.
(3) on steel plate 3, there is bight up and down, in the scraper plate mode, can cause the accumulation of dirt settling in this bight.
(4) when dirt settling is tar, the quality softness, only with scraper plate through not removing fully sometimes.

The structure of present embodiment bell clearing apparatus, as mentioned above.Bell 1 utilizes bell handler (door riser) to be unloaded from coke oven, and revolves and turn 90 degrees, with the bell clearing apparatus over against.At this moment, side swabbing pig 20 is positioned at upper limit position.Then, from high pressure water rotary-jet rifle 201,201 inject high pressure water, while and rotate that (for example, 40～80mm/sec) begin to make side swabbing pig 20 to descend with low speed.And, when the rotary cutter 202,202 on being installed in side swabbing pig 20 arrives the upper level part 5d of lagging material 5 of bells 1, make cylinder 206 actions of opening and closing device 203, rotary cutter 202,202 is pressed in the upper end of lagging material 5, utilize oil motor 205,205 to drive rotary cutter 202,202 rotations simultaneously, and be converted at a high speed (for example, 90～180mm/sec) and begin to make side swabbing pig 20 to descend constantly by this.
Be attached to tar, carbon black on the bell 1, few and past more bottom is many more on top.Therefore, the translational speed of side swabbing pig 20, at about height location of about 1/4 from the bottom of short transverse, with rate conversion be once more low speed (for example, 40～80mm/sec) and drop to lower limit, stop the rotation of high pressure water rotary-jet rifle 201,201 and the rotation of high-pressure water jet and rotary cutter 202,202 in the lower position, make cylinder 206 actions of opening and closing device 203 simultaneously, and discharge rotary cutter 202,202 pushings from lagging material 5.
When side swabbing pig 20 is positioned at the lower position, from the high pressure water rotary-jet rifle 401 inject high pressure water of top swabbing pig 40, while and rotate with swabbing pig above the high-speed mobile 40.Because adhesion amounts such as the tar of the gas passage upper level part 7d of bell 1, the upper front end horizontal component 4d of knife-edge support 4, carbon black are few, so need not move with low speed.Swabbing pig 40 counter-rotating on the mobile terminal makes, and put with the high speed restoring to normal position, and stop the rotation and the high-pressure water jet of high pressure water rotary-jet rifle 401 at allocation, finish cleaning works.Be left in the degree on the upper level part 5d of lagging material 5 according to pyrogenous coke, do not have adherent tar, carbon black.Therefore, even rotary cutter 202,302 as side swabbing pig 20 or following swabbing pig 30 is not set, only get final product with a scraper plate 402.
After the cleaning works of swabbing pig 40 is through with in the above, from high pressure water rotary-jet rifle 201, the 201 inject high pressure water of the side swabbing pig 20 that is positioned at lower limit, while and rotate with the low speed side swabbing pig 20 that begins to rise.When the rotary cutter 202,202 of side swabbing pig 20 arrives the position of lower horizontal part 5c of lagging materials 5, make cylinder 206 actions of opening and closing device 203, rotary cutter 202,202 is pressed in the bottom of lagging material 5, utilize oil motor 205,205 to drive rotary cutters 202,202 rotations simultaneously, and side swabbing pig 20 is risen to be converted to lower-speed state till the position of low speed when descending.Rise to upper limit position from the speed transformation point with high speed, stop the rotation of high pressure water rotary-jet rifle 201,201 and the rotation of high-pressure water jet and rotary cutter 202,202 at upper limit position, make cylinder 206 actions of opening and closing device 203 simultaneously, discharge rotary cutter 202,202 pushings from lagging material 5, the cleaning works of side swabbing pig 20 finishes.
The allocation of following swabbing pig 30 is central authorities.When side swabbing pig 20 is positioned at upper limit allocation, make cylinder 306 actions that are installed on the lifting device 303 on the following swabbing pig 30, rotary cutter 302 is pressed on the lower horizontal part 5c of lagging material 5, makes rotary cutter 302 rotations with oil motor 305 simultaneously.At this moment, high pressure water rotary-jet rifle 301 also rises to the cleaning position of the lower horizontal part 4c of the lower horizontal part 7c of gas passage 7 and knife-edge support 4 front ends.At this moment, from high pressure water rotary-jet rifle 301 inject high pressure water, and while rotate make with low speed below swabbing pig 30 after (or left) walked crosswise to the right, end makes its counter-rotating on right (or left side), then, make following swabbing pig 30 left (or to the right) walk crosswise, after a left side (or right) end makes its counter-rotating, return central authorities.Put the rotation that stops high pressure water rotary-jet rifle 301 and the rotation of high-pressure water jet and rotary cutter 302 in centrally-located, make cylinder 306 actions of lifting device 303 simultaneously, and discharge pushing from lagging material 5 to rotary cutter 302, below the cleaning works of swabbing pig 30 finish.
Certainly, in the action of each swabbing pig 20,30,40, starting high pressure water, hydraulic pressure, air pressure, electric each equipment is precondition.About high pressure water, be to fetch water from the face of land, and be stored in water supply tank with the water supply funnel.From the water supply method on the face of land, automatic water-supply that uses the motor valve and the manual water supply that connects flexible pipe with manpower are arranged.In addition, water quality is tap water (tap water) in principle, but can by water supply line set up strainer midway, can use process water or recirculated water.In addition, utilize mobile apparatus equipment as hydraulic power source, pneumatic supply mostly.On method of operation, can select full-automatic or manual.Above-mentioned sequence of operation is shown in example, and certainly change freely in proper order.
Being characterized as of the bell clearing apparatus of present embodiment: (1) has also used high-pressure water jet power (high pressure water rotary-jet rifle 201,301,401) and mechanical cutting (rotary cutter 202,302), (2) traveling time of many grades of conversion side swabbing pigs 20, (3) guarantee the cleaning effective width of high pressure water rotary-jet rifle 201,301,401.
The dirt settling that utilizes the jet power of high pressure water to remove bell 1 is the emphasis of present embodiment, but also is emphasis with mechanical rotary cutter 202,302 and its combination.Only, comprise lagging material 5 and can remove (cleaning) dirt settling, but, need a large amount of water for this reason because the sweep area of lagging material 5 is big with the jet power of high pressure water, and, the problem of the quenching of lagging material 5 also can take place because of using a large amount of water.
Remove the gas passage 7 of bell 1 and the dirt settling of knife-edge support 4 front ends, its bell remove original purpose be prevent the pollution of the environment, the coke ashing, but remove the side of lagging material 5, following, top dirt settling, be when bell is installed on coke oven for the operational requirement of surplus, do not require integrity.Therefore, get final product with rotary cutter 202,302.In addition, because the just temperature height of the bell 1 that takes off from coke oven, so should reduce the water yield of use as far as possible.
Utilize the cleaning effect of high-pressure water jet, determined by the surging force that gives dirt settling removing face (cleaning face).Surging force is shown below.
F: the surging force (kgf) of removing face
Q: injection flow rate (L/min)
G: universal gravity constant (9.8m/s
2)
P: spraying pressure (kgf/cm
2G)
S: distance (cm) from spray nozzle front end to the cleaning face
L: to the distance (cm) of the arrival face of injection
The L of following formula is the value with the nozzle performance decision, common L 100cm, and the boundary of S is 30～50mm (with reference to Fig. 6).In addition, in order to improve cleaning effect necessary surging force, from various experiments and actual effect as can be known, be the relation of F＞3.0kgf.
Gas passage 7 has adhered to tar, carbon black in the dry distillation of coal, stopped up gas passage, and the ratio that this gas passage sectional area is blocked is called plugging rate, and represents with per-cent (%).Be used to remove the cleaning energy (jet power) that stops up tar, carbon black, with the product representation of the water yield and pressure, it concerns as shown in Figure 7.When the jet power of high pressure water is certain (350kgf/cm for example
2～550kgf/cm
2) time, and plugging rate 100% dropped at 20% o'clock, that is, the improvement rate is that 80% needed flow is about Q
L 25L/min.But the bell clearing apparatus of present embodiment all uses with each release coke to be condition, because of the plugging rate of a dry distillation of coal does not reach 100%, is 70～80%.Therefore, the improvement rate of this moment is 50～60%, also can reduce to clean energy (required flow) (Q
L 15～18L/min).
From the water of nozzle ejection, as shown in Figure 6, its straight ahead arrives dirt settling and removes face (cleaning face), and destroys dirt settling, and experimental result is that its destruction width is about 10 times of nozzle diameter.For example, effective cleaning width of φ 0.7mm bore nozzle is 7mm.Therefore, the high-pressure water jet orbit interval is that 7mm is an essential condition.Make high pressure water rotary-jet rifle 201,301,401 while rotate, 20,30,40 o'clock injection track of mobile swabbing pig as shown in Figure 8.
Utilize the jet power of high pressure water to remove the gas passage 7 of dirt settlings such as tar, carbon black, have certain width, and because of stove group (battery) different.In addition, not only gas passage 7, effectively clean width and also must comprise knife-edge support 4 front ends.The high pressure water rotary-jet rifle 201,301,401 of present embodiment, can be by changing nozzle installing space (being 80mm among the figure) shown in Figure 8, can will effectively clean width and be suitable for the gas passage width, and can enlarge effective cleaning width by changing the setting angle of nozzle.
On the other hand, with reference to Fig. 9, with following formula can obtain rotary cutter 202 cutting be attached to lagging material 5 lateral, by the carbon black change the cutting force of tar.
P=K
pBh
m(formula 2)
P: required cutting power (kgf)
K
p: the cutting power (kgf/mm of unit
2)
B: what be cut adheres to carbon black width (mm)
h
m: average carbon black thickness of cutting (mm)
According to following formula, as if being 5mm by removing the accompanying amount of carbon blacks of a dry distillation of coal once with cutting unit, then standard is P 170kgf.But, in fact since side swabbing pig 20 make lifting action, so by the cleaning face number of times be twice.
At this moment, on the short transverse of bell 1, the amount difference of accompanying tar, carbon black.That is, top, pars intermedia are fewer, more down many more.When on one side when high pressure water rotary-jet rifle 201 inject high pressure water move it on one side, the cleaning energy that translational speed is then cleaned face slowly is big.Therefore, can accelerate translational speed at the top and the pars intermedia of the little bell 1 of plugging rate, and, along with slowing down toward the bottom operation.The dirt settling amount of bell 1 length direction generally is above-mentioned tendency, but the tendency difference of each bell 1.The bell clearing apparatus of present embodiment has adopted frequency control system in the lifting driving control of side swabbing pig 20, can adhere to trend and the translational speed of stepless change side swabbing pig 20 according to tar, the carbon black of bell 1.And, can also realize the shortening of the time of cleaning with this.
More than, according to the bell clearing apparatus of also using the present embodiment of high-pressure water jet power and mechanical type rotary cutter, the effect of its acquisition is: (1) is because the dirt settling removing method of gas passage 7 is to utilize the noncontact mode of high-pressure water jet power, so can not bring damage, (2) even the core of deciding of bell 1 and bell clearing apparatus has all around skew, but because of the high-pressure water jet width has affluence, therefore can obtain to clean fully effect, (3) owing to utilize the cleaning method of high-pressure water jet power, mechanically do not contact with cleaning face, so also can easily pass through the bight up and down of gas passage 7, in addition, because dirt settling disperses because of jet power, so the accumulation of dirt settling can not take place, (4) adhere to the tar temperature when high, be soft ground, but owing to utilizing inject high pressure water to make its cooling, and it is dispersed with jet power, even also can remove so matter is soft, (5) jet width by high pressure water is added and expands the width that can comprise knife-edge support 4 front ends to and can clean, and does not have damage.
In addition, driving side swabbing pig 20 liftings is electric motor.By this electric motor of variable frequency control, can infinitely change rising or falling speed.Different with the bell clearing apparatus of conventional art, can with this to the few bell top of hard and adhesion amount with high speed lifting, soft and bell bottom that adhesion amount is many with low speed elevation, in the limited time (coke is released the time (about 2 minutes)), obtain the cleaning effect of the best.
And, the bell clearing apparatus of present embodiment, use constrictive cylinder 206,306 with rotary cutter 202,302 press to lagging material 5 sides and below, can improve the concavo-convex rapid reaction of corresponding cleaning face, and improve 202,302 pairs of driven property of cleaning face of rotary cutter, can remove dirt settling in noresidue ground.Promptly, when on actuator, using hydraulic pressure, because hydraulic efficiency oil is incompressibility liquid, so to lagging material 5 sides and below concavo-convex slow in reacting, be difficult to closely contact with cleaning face owing on actuator, used constrictive pressurized air, so can corresponding sensitively lagging material 5 sides and below concavo-convex, about and off-centre, inclination up and down, with hydraulic pressure mutually specific energy rotary cutter 202,302 is more closely contacted with cleaning face, and can improve the cleaning effect.
In addition, the bell clearing apparatus of conventional art, because the cleaning method of its gas passage 7 is mechanical scraper plate modes, therefore must advance to bell 1 just to make it to the center, but when the time to the cleaning direction inject high pressure water of gas passage, can be with the position of rotation of the installation site of clearing apparatus and bell 1 to the center, and can not need bracing frame and front and back driving and reversing mechanism and can adopt fixedly, can shorten time at center and improve the center precision.In addition, also needn't as in the past, make bell clearing apparatus front and back advance and retreat.
In addition, for bell clearing apparatus and bell to the center, side swabbing pig 20 possesses opening and closing device 203, make rotary cutter 202,202 about surplus is arranged.If the cleaning agency (high pressure water rotary-jet rifle 201) of gas passage 7 can be installed on the rotary cutter installation bracket (part of lifting chassis 200), then can carry out the center with gas passage 7 more accurately.Because it is scraper plate that the gas passage of the bell clearing apparatus of conventional art is removed mechanism, so can not do like this, but the bell clearing apparatus of the high pressure water of present embodiment and usefulness, gas passage cleaning agency are the high-pressure water jet formulas, thus can with rotary cutter 202,202 shared stands.Therefore, can improve the cleaning effect again exactly to the center.
In addition, bell clearing apparatus of the present invention is not limited to the foregoing description, in the scope that does not break away from aim of the present invention various changes is arranged certainly.
For example, will be attached to tar on the bell 1 with inject high pressure water and mechanical cutting, when carbon black is removed, remove thing and be bonded at spray nozzle front end sometimes, stop up jet orifice.In order to take precautions against its generation, as shown in figure 10, preferably go up installation and have the cover 201c (301c, 401c) that passes through peristome 201d (301d, 401d) corresponding to the high pressure water of nozzle 201a (301a, 401a) front end nozzle diameter at nozzle bearing 201b (301b, 401b).At this cover 201c (301c, 401c) inside, owing to pass through high pressure water, so be always negative pressure, when covering 201c (301c at this, installation side 401c) is provided with peristome 201e (301e, in the time of 401e), atmosphere is attracted, and pass through peristome 201d (301d from the high pressure water of cover leading section, the air that 401d) is attracted, to be blown on the cleaning face with high pressure water at a high speed, can remove the tar on the cleaning face of being attached to effectively, dirt settlings such as carbon black, with only compare with high-pressure water jet, the cleaning effect can be further improved, and the obstruction of nozzle can be prevented.
In addition, when stopping the injection of high pressure water, because of siphonage can temporarily be in negative pressure in nozzle is supplied with the high pressure water pipeline, and will fly in the airborne dust inlet nozzle, dust is the bridge formation shape and is deposited in the nozzle when inject high pressure water next time, causes obstruction, in order to prevent its generation, preferably when stopping high-pressure water jet, automatically in the high pressure water pipeline, supply with pressurized air, make it be in malleation, and do not attract dust.
In addition, side, following soft tar, the carbon black of also having adhered to of the lagging material of removing with rotary cutter 202,302 5, when removing with rotary cutter 202,302, cause the obstruction that is attached to the cutting unit slot part, the device of preferably inciting somebody to action, clean, clean the rotary cutter 202,302 of this blocked state be arranged on side swabbing pig 20 and below the allocation of swabbing pig 30.This washing unit, have a plurality of nozzles of arranged spaced in accordance with regulations, after cleaning finishes, when the rotary cutter 202 of side swabbing pig 20 and below the rotary cutter 302 of swabbing pig 30 when restoring to normal position is put respectively, utilize nozzle ejection high pressure water or pressurized air, cleaning rotary cutter 202,302.At this moment, rotary cutter 202,302 is rotated with its week entirely of high pressure water or blast injection.
