Description
Technical field
The utility model relates to a kind of coke oven maintenance and uses instrument, particularly a kind of coke oven bridge tube inwall graphite clearing device.
Background technology
The synoptic diagram that Fig. 1 derives for coal oven dithio-gas, in the coking production process, bridge tube 3 is connected with effuser 4 with the upcast 2 of coke oven 1, is one of visual plant of raw gas derivation.And coke oven graphite be raw gas under high temperature action, some macromolecular hydrocarbons decomposes and produces methane or hydrocarbon, uncombined carbon and hydrogen are separated out in the pyrolysis under high temperature action of part methane and hydrocarbon, uncombined carbon is attached on the coking furnace shaft, finally forms graphite.Coke oven growth of graphite speed is generally relevant along with coke oven production run state, and especially along with the coke oven increase in furnace life, the growth of graphite and deposition conditions are more serious, have significantly reduced the useful volume of gas flue.For this reason, the removing to bridge tube 3 place's graphite 5 just seems extremely important.Along with the growth of graphite depositing time, its compactness extent increases, and density and degree of graphitization are higher; Void content is low, and reactive decline is difficult to remove; And along with graphite 5 constantly deposits at bridge tube 3 inwalls; Raw gas is derived passage and is dwindled rapidly, thereby causes raw gas to derive difficulty, and fire door, stove frame are smoldered in a large number and burned with anger.For this reason, all coke-oven plants nearly all adopt artificial eradicant eating to remove graphite 5, promptly by force graphite are removed in bridge tube 3 with perching knife with artificial; But because bridge tube 3 cleaning spatial restrictions; After perching knife stretches into from access opening 6, only can clear up by the interior graphite of certain angle, the graphite excessive for angle, that perching knife is difficult to touch just is difficult to remove; And operational difficulty, labour intensity is big.
The utility model content
For addressing the above problem, the utility model provides a kind of coke oven bridge tube inwall graphite clearing device, can clear up the sedimentary graphite of bridge tube inwall effectively, thereby guarantees the unobstructed of raw gas derivation passage.
For realizing above-mentioned purpose, the coke oven bridge tube inwall graphite clearing device of the utility model comprises mandrel, fixed sleeving and a plurality of scraper; The end of said mandrel is provided with disk; Said fixed sleeving is enclosed within on the said mandrel, and said mandrel is provided with clutch shaft bearing, and said fixed sleeving is provided with second bearing; The outside of the said clutch shaft bearing and second bearing is welded with first nut and second nut respectively, and said first nut can be connected the location through screw rod with second nut; Said fixed sleeving is provided with rotating disk, and said rotating disk is enclosed within on the said mandrel, and said rotating disk is connected through the 3rd bearing with fixed sleeving; Each said scraper is hinged through a knife bar and said disk, and the middle part of said knife bar is connected with said rotating disk through connecting rod, and the two ends of said connecting rod are hinged with the middle part and the rotating disk of said knife bar respectively.
Said scraper adopts spring steel to make.
Coke oven bridge tube inwall graphite clearing device through the utility model; Make that sedimentary graphite is able to remove effectively in the bridge tube, guaranteed the unobstructed of gas flue, avoided because bridge tube graphite deposition causes gas flue not smooth; Guarantee that coking chamber pressure is normal; Simultaneously, eliminated in the process of coalingging the situation that derives the coal gas of freely not overflowing in a large number because of raw gas, obvious effects has been arranged improving environment.And, adopt the coke oven bridge tube inwall graphite clearing device of this utility model, operation is convenient, has alleviated labour intensity.

Embodiment
Shown in Fig. 2～4; The coke oven bridge tube inwall graphite clearing device of the utility model comprises mandrel 10, fixed sleeving 20 and a plurality of scraper 30; The end of said mandrel 10 is provided with disk 11; Said fixed sleeving 20 is enclosed within on the said mandrel 10, and said mandrel 10 is provided with clutch shaft bearing 12, and said fixed sleeving 20 is provided with second bearing 22; The outside of the said clutch shaft bearing 12 and second bearing 22 is welded with first nut 13 and second nut 23 respectively, and said first nut 13 can be connected the location through screw rod 40 with second nut 23; Said fixed sleeving 20 is provided with rotating disk 21, and said rotating disk 21 is enclosed within on the said mandrel 10, and said rotating disk 21 is connected through the 3rd bearing 210 with fixed sleeving 20; Each said scraper 30 is hinged through a knife bar 31 and said disk 11, and said scraper is fixed on a side end of knife bar 31, and the end side of knife bar and said disk 11 are hinged; The middle part of said knife bar 31 is connected with said rotating disk 21 through connecting rod 32, and the two ends of said connecting rod 32 are hinged with the middle part and the rotating disk 21 of said knife bar 31 respectively.
Because graphite material is very hard, the scraper 30 of the coke oven bridge tube inwall graphite clearing device of the utility model can adopt spring steel to make.A plurality of said scrapers 30 are uniform distribution preferably along the circumferential direction.
The coke oven bridge tube inwall graphite clearing device of the utility model partly inserts scraper in the bridge tube through access opening in use.In use, fixed sleeving 20 can be erected at and keep on the access opening not rotating.
Before operation, because bridge tube access opening diameter is less, for the coke oven bridge tube inwall graphite clearing device that guarantees the utility model can insert in the bridge tube, this device is contraction-like, promptly shown in Figure 2 state before entering.Treat that scraper 30 gets in the bridge tube, mandrel 10 is pulled back, make head scraper 30, be the expansion shape, state as shown in Figure 4 by the horizontal certain angle that opens up into gradually.Being threaded through screw rod 40 and first nut 13 and second nut 40 then; With the locking position of mandrel 10, at last mandrel 13 is connected with motor, under the rotation of motor with fixed sleeving 20; Scraper 30 is circumferential motion; Can the graphite spatula on the bridge tube inwall be got off, thereby guarantee the unimpeded of bridge tube, make to get into effuser in the raw gas smoothly.
