The utility model patent that name is called porcelain axle box (Granted publication number is CN201399380Y, February 10 2010 Granted publication day) discloses a kind of structure of porcelain axle box, and its bottom at least a portion is downward-sloping and move closer to deduster main body.Through practice, find, the effect that bottom only has part to tilt not is fine, and sloping portion dust stratification is more not serious for it.Owing to there is no firing equipment in case, so humidity is wayward, insulation effect is undesirable.Owing to there is no manhole, the service work of porcelain axle box must be carried out from deduster inside, very inconvenient in addition.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of electrostatic precipitator the cloudy porcelain axle box of beating, the problems such as the interior flashover easily occurring in solution original structure, electric discharge, short circuit, guarantee that electrostatic precipitator can normally move, improve operation and overhaul efficiency, guarantee the effect of dedusting, protection against the tide and deashing.
The technical solution of the utility model is: the cloudy porcelain axle box of beating of a kind of deduster, mainly by base plate, top board and side plate, surrounded, between base plate and top board, there is the included angle A of 30 °～45 °, on the extension outer wall of base plate, be attached with successively heat-insulation layer and color steel watt, on side plate, have population door.The outer wall of base plate and top board one end is connected with electrostatic precipitator outer wall by welding manner.The cloudy base plate of making porcelain axle box tilts 30
o～45
oand after extending, be connected with electrostatic precipitator wall, so the moon is beaten the inwall of porcelain axle box base plate, be connected with electrostatic precipitator wall inwall, both outer walls be closely connected.Such connected mode is without re-using dust excluding plate, and porcelain axle box and deduster are in direct communication with one another.During due to common installation porcelain axle box, top board is parallel to horizontal direction, so base plate just has one 30 with horizontal direction
o～45
oinclination angle, the cloudy dust stratification of beating in porcelain axle box just can be drained under the impact of deadweight in natural landing, accumulation that can be not too high.Through repetition test proof 30
o～45
oangle be optimal values.Owing to there being the existence at this inclination angle, base plate is equivalent to make porcelain axle box to whole the moon has increased a support on the other hand, has improved its fixing firm degree.Population door on side plate is for convenient maintenance, particularly changes the internal components such as porcelain axle, needn't take porcelain axle box apart or enter deduster inside and overhaul, and has avoided destroying existing sealing.
In base plate, there is porcelain axle heater, guarantee inner heating, can keep the humidity of porcelain axle box inside like this, avoid because of boiler, electrostatic precipitator stop transport after inner flue-gas temperature decline and cause the reduction of the insulaion resistance that makes moist, when electrostatic precipitator and boiler put into operation again, there will not be and beat the porcelain axle box abnormal situation that puts into operation of making moist because of the moon.
Extension has blows grey hole.Generally, whole porcelain axle box is airtight, but move after a period of time inside, still have dust and adhere to, then can blow grey hole and suck extraneous natural air by natural negative pressure operation by opening, or external air pump is to carrying out deashing in case.
The cloudy outer wall of beating porcelain axle box base plate is connected by welding manner with the outer wall of electrostatic precipitator wall, and the welding of connecting portion must be strengthened, and guarantees well to support the cloudy porcelain axle box of beating.
The cloudy extension outer wall of beating porcelain axle box base plate must install heat-insulation layer and color steel watt additional, attractive in appearance on the one hand, safety on the other hand, because electrostatic precipitator run duration internal temperature by heat transfer to outside, therefore must avoid occurring to scald people's situation appearance.
The utility model is very good by long-term operation proving effect, the cloudy interior dust stratification of porcelain axle box of beating significantly reduces, guaranteed cloudy porcelain axle box inner drying degree (humidity) substantially constant of beating, solve electrostatic precipitator and beaten the problems such as electrostatic precipitator cisco unity malfunction that in porcelain axle box, flashover, electric discharge, short circuit cause because of the moon, got rid of the generation of the electrostatic precipitator fault rate causing because of short circuit, flashover, guarantee that the operation insulation of electrostatic precipitator is more than 100M Ω, improved operational efficiency, facilitate service work, improved the dust removing effects of electrostatic precipitation.
