Description
Technical field
The utility model is related to the automatic cleaning device that net is roused for sea water filter, for rousing the drum in net to sea water filter
Network framework carries out automatic cleaning.
Background technology
Current sea water filter drum net species is a lot, and drum type filter screen is one of which.Drum net is one and net is circumferentially housed
The rotational circle cylinder of piece, seawater enters drum net inside from both sides end face, and 3mm tiny microorganism is less than by wire side filter diameter
And after other impurity, circumferentially outer water outlet, its filter water includes being supplied to cooling water of nuclear power system etc..The equipment needs length
Time operates, once failure, influences the offer of nuclear reactor cooling water, accident easily occurs.
Drum net is global facility, and including drum network framework, skeleton outer cover wire side, elevator bucket is put positioned at skeletal internal level
Put, with the rotation of skeleton, continuously clear up the dirt impurity that drum net inside is entered after filter, rushed after lifting to platform with water
Walk, because skeletal internal dirt is easily accumulated to center, elevator bucket can not fill dirt close to outer end, in half dummy status,
Not only elevator bucket utilization rate is low, and the water flow velocity excessively of the influence channel water inlet of skeletal internal dirt accumulation and wire side, makes in skeleton
Outer water-head is more than 0.8m, and immense pressure is produced to skeleton structure, can result in damage parts, influences the service life of product,
Increase maintenance cost.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of automatic cleaning device that net is roused for sea water filter,
It can just realize that parts are transformed in the time between overhauls(TBO) of nuclear power system equipment, beneficial to the service life of extension drum network framework, save
Manually drag for dirty cost and system maintenance expense, it is ensured that the normal operation of nuclear power system.
To solve problem above, concrete technical scheme of the present utility model is as follows：It is a kind of for sea water filter rouse net from
Dynamic clearing apparatus, central rotating shaft drives drum net rotation, skeleton is provided with the inside of drum net, provided with pendulum on intraskeletal crossbeam
It is flexibly connected raking arm on axle, balance staff, the top connection stay cord of raking arm, the middle part of raking arm is connected by extension spring with skeleton；Its
Medium pulling rope bypasses the pulley connected on skeleton and stretches out drum net；Several wedge shapes provided with circle distribution outside the periphery of drum net
Guide pad, the end for stretching out the drawstring of drum net is provided with roller bearing, the surface contact slide of roller bearing successively with wedge-shaped guide pad.
The end of described drawstring is provided with pull rod shaft, and guide sleeve is provided with the inner surface of drum net, and pull rod shaft passes through guide sleeve
It is connected afterwards with roller bearing.
Described wedge-shaped guide pad is symmetrical structure, and centre is provided with stopper slot, and the pull rod shaft being connected with roller bearing passes through spacing
Groove.This is used to sea water filter and rouses automatic cleaning device of net using with the rotation of drum net, and roller bearing is along fixed wedge shape
The inclined-plane upward sliding of guide pad, and pull raking arm to be swung in skeleton by pulley driving steel wire rope, when roller bearing is led from wedge shape
When being fallen on to block inclined-plane, extension spring resets raking arm, so as to complete raking arm in intraskeletal reciprocally swinging, raking arm pendulum
Continuously skeletal internal dirt is cleared up to both sides in dynamic process, it is ensured that the elevator bucket of both sides is filled and discharged after dirt.
Part strength is not only improved, and ensure that the position of roller bearing provided with pull rod shaft and through guide sleeve in the end of drawstring
Wedge-shaped guide pad can not be departed from during rotating repeatedly by putting, it is ensured that everything goes well with your work is carried out.
Wedge-shaped guide pad is symmetrical structure, and centre is provided with stopper slot, it is ensured that roller bearing even running on lozenges.
