Description
Technical field
The invention belongs to solution and will mainly rely on the nonmetal carrier bar mud scraper of equipment of import in the key technology of safety and application facet at present, be specifically related to the chain rupture error protection and reach the method for refuting chain fast.
Background technology
Over year, the nonmetal carrier bar mud scraper of import is widely used at China's water treatment field surplus in the of nearly ten.This nonmetal carrier bar mud scraper is to be made of scraper plate, chain, sprocket wheel and motor etc., and wherein most of parts are by the nonmetallic materials manufacturing, so it has the performance of light weight and erosion resistant.Nonmetal carrier bar mud scraper is applied in the square type horizontal sedimentation tank of the dark 4.5m of the wide 8m* of long 50m* usually, the two ends that scraper plate are about 7.8m are installed in respectively on the driving chain that is layed in the sedimentation basin both sides, drive chain by power chain, the scraper plate that makes spacing be about 3m constantly is transported to the mud at the bottom of the pond in the spoil disposal ditch, the scum silica frost of pond face is struck off in the skimming pipe discharge (as shown in Figure 1).But the chain rupture fault can take place in the chain of this mud scraper unavoidably, and its reason is relevant with the device structure characteristics with nonmetal chain characteristic:
Nonmetal chain characteristic
1, because selecting non-metallic material difference and manufacturing forming process difference thereof for use, can there be indivedual chain links or bearing pin bubble to occur in the local area unavoidably, influence quality and fluff because imbibition makes the elasticity of chain closed-loop after the operation with dropping in the water, break or break chain easily.
2, chain normally tensile strength is big and compression strength is little.Such as the chain link of the U.S.-HS730 of company type fiberglass after testing the maximum Fracture Force of its tensile strength be 8.5 tons, and the maximum Fracture Force of compression strength only has 0.4 ton.
3, chain be broken chain in aging meeting of later stage because mechanical performance produces relaxation phenomenon.Oneself decays to 7.5 tons to recheck its tensile strength such as HS730 type fiberglass chain link after using 2 years, and finds after 7 years that in operation the fracture of chain link has become to tear shape.
The device structure characteristics
1, the length of chain closed-loop has 100m, and the span between the sprocket wheel is big, causes the linearity of driving chain center line overproof during installation easily, has influenced the normal engagement of chain and sprocket wheel and chain is broken.When forward and backward changed course sprocket wheel 4 and 3 plane verticality deviation at the bottom of the hypothesis pond are 1 when spending, deviate=the 50000*sin1/cos1=871mm of the linearity of driving chain center line then, and sprocket wheel thickness is 31mm, the chain drum width is 50mm, its deviate has just substantially exceeded design permissible value (50 1 31)=19mm, even if chain is to flexibly connect normal engagement that also cannot say for sure to demonstrate,prove chain and sprocket wheel.
2, the wear extent increase of the axle sleeve (nylon) that cooperates with spool (stainless steel 316) of changed course sprocket wheel can cause the beat amount of sprocket wheel to increase thereupon, can break chain easily. and when the beat amount surpasses 19mm, mud scraper just takes off chain or chain rupture at once after startup, can't move fully.
When chain when the chain rupture fault takes place at the bottom of the pond; cause all torsional deformations or fracture of all scraper plates because can not in time shutting down; the solution of existing fault is: refute chain at the bottom of allowing maintenance mans fall the pond again after the sewage in the pond is all discharged; the sewage that this method is discharged can cause secondary pollution; and water discharge time is long; influence is produced and is reduced equipment efficiency of usage, and operation inconvenience.60 of a certain company of the Guangdong purification of water quality factory import U.S. nonmetal carrier bar mud scrapers for example, the length of this nonmetal carrier bar mud scraper is 115m, wide is 8m, dark is 4.5m, when at the beginning of 04, putting into operation, just taken place ten then surplus time chain rupture fault, and all make the destruction of going to wreck property of equipment at every turn, scraper plates all in pond torsional deformation or fracture all, often want two weeks repair time approximately and surplus lose ten ten thousand yuan.Also having 60 equipment of this factory is to be distributed in south, each 12 Da Chi of two districts, north, and each Da Chi is communicated with by 5 Xiao Chi and forms.When chain rupture has taken place a certain equipment, then going back untreated sewage in 5 Xiao Chi all wants simultaneously discharging simultaneously clean, refute chain at the bottom of allowing maintenance mans fall the pond again, the sewage of 20,000 tons (115m*8m*4.5m*5=20700 tons) of so not only having an appointment can cause secondary pollution, and draining simultaneously needs the time long.
Be CN200957311Y " modified mud scraper protective device " as notification number in the prior art; this device can be by adjusting the position of detection probe; make detection probe can fast detecting have the chain rupture fault of nonmetal carrier bar mud scraper; and stop the work of nonmetal carrier bar mud scraper immediately automatically, thereby intact protection equipment.This patent is mainly carried out the chain rupture protection to nonmetal carrier bar mud scraper; stop fault further to enlarge and damage whole equipment; but this patent does not solve the reparation problem after the chain rupture, refutes chain at the bottom of falling the pond after maintenance mans can only adopt existing method for maintaining with sewage discharge in the pond.
