Description
Technical field
The utility model is related to a kind of thermal power plant ball cleaning apparatus of condenser, specially a kind of condenser ball is clear
Horizontal ball-net apparatus in washing.
Background technology
Currently, with the rapid development of the national economy, generating set capacity is increasing, thermal power plant condenser ball
Cleaning device more and more uses horizontal arrangement.But the horizontal ball screen that market provides, there is no because of arrangement side
The change of formula and change, the horizontal ball screen of market popularity only install two support bases additional on the basis of vertical ball screen and
, therefore the ball collecting rate of ball cleaning apparatus is caused to further decrease, equipment failure rate further increases.
There are many ball screen form that power plant uses, and most widely employed is SF type ball screens (see power industry standard
DL/T581-95, ball cleaning apparatus of condenser and recirculated water secondary filter).SF types ball screen when receiving spherical state, by
One electronic execution machine drives two movable screen rotations by transmission mechanism, and the top edge of two movable screens is made to coincide, under
Edge is adjacent to outer casing inner wall, and it is in "∧" type to make two movable screens, and glueballs is stopped by web plate and being glided along net item at this time, through glue
Ball fairlead sucks glueballs pump intake for recycled.Using initial stage, receiving ball efficiency can also reach SF types ball screen
Standard is then just gradually reduced, or even is forced to deactivate, the main reason is that movable screen is connected with transmission shaft using Ω type axle clamping plates
Mode is connect, loosening is easy tod produce, movable screen top edge and lower edge is caused the gap of wide arc gap, especially top edge occurred
It is 2 times of lower edge gap, glueballs is made to run away from there.When this horizontal placement of form ball screen, technological deficiency originally can quilt
It is further amplified, simultaneously because the effect of weight of web plate itself, causes web plate upper and lower gap to change, in turn results in web plate bite,
The unlatching of web plate, closure can not in place, and glueballs is largely escaped to lose.In addition, since glueballs outlet is arranged on pipe centerline, machine
Pool-size is bigger, and the bottom of pipeline and the difference in height of center line are bigger, and the glueballs for entering ball screen is returned in minimum point
It receives, therefore a large amount of glueballs for losing kinetic energy can be gathered before glueballs outlet.Problem above causes the glueballs of horizontal ball screen
The rate of recovery is more undesirable, and equipment service efficiency is lower.
Invention content
The utility model is related to a kind of horizontal ball screen for ball cleaning apparatus of condenser, the purpose is to provide one
Kind improved waterpower self-locking step on the basis of original "∧" type ball screen is promoted and strength recoils from the horizontal ball screen of disturbance,
The efficiency for receiving ball can be greatly improved, and can be come into operation for a long time.
A kind of technical solution of horizontal ball screen for ball cleaning apparatus of condenser of the utility model is realized in
's：In two movable screen top edges of entrance side anastomosis of ball screen setting, one arc head being fixed on outer casing inner wall
Spacing board makes not will produce dynamic deflection and running clearance herein, this is rigidly overlapped, and ensures that ball screen realizes waterpower self-locking work(
Energy；The rotation axis of ball screen movable screen is connected with connecting plate, connecting plate and the slab strip adoption bolt on movable screen
It tightens, connecting plate is made to be fastened together with movable screen, therefore ensure that ball screen movable screen longtime running not will produce loosening,
The rigidity of movable screen is also added simultaneously.An arc lower jaw ring is connected below in contact of the recycling bucket with outer casing inner wall, is kept away
When exempting from equipment operation thus sponge glueballs is omitted.Observation window is set on glueballs fairlead, the fortune of sponge glueballs in observing system
Row situation, while situation, by the adjusting screw rod of transmission mechanism, can be eliminated in time possible in equipment operation according to the observation
The gap of appearance.The ball screen of horizontal arrangement is disposed with three-level disturbing flow device in the entrance of ball screen between receipts ball mouth, to recycling
Sponge glueballs carry out jump-lift, ensure glueballs will not be gathered in net because of factors such as flows, to influence ball collecting rate.
Assemble thrust bearing in the lower part axle bed of ball screen, ensure web plate will not change because of the dead weight of web plate web plate fit-up gap and
The rotation flexibility of web plate, therefore the appearance of bite phenomenon is avoided in equipment running process.In the vertical wire side in the back side of ball screen
Location arrangements have two rows of nozzles, be connected to the outlet of glueballs circulating pump, after pipeline connection, flow that glueballs circulating pump is got
By series of spray nozzles, ball screen is directly sprayed from the ball screen back side, ball screen is formed and forces backwash, while flow is direct
It is ejected into the glueballs being recovered on ball screen face, glueballs can be made to form tabbing, the recycling kinetic energy of glueballs is effectively increased, avoids glueballs
Possible siltation.
The utility model uses above-mentioned innovation scheme, forms completely new waterpower self-locking step promotion and strength recoil is disturbed certainly
Move horizontal ball screen so that ball screen is increased to ball collecting rate 98% or more, and equipment can put into progress for a long time, and that improves equipment can
By property.Have the beneficial effect that waterpower self-locking step ball screen plate, step promote glueballs recycling height, the recoil web plate back side assigns back
Receive the new kinetic energy of glueballs, main shaft bottom thrust bearing ensure web plate do not block, be not puckery, not play, it is mounted on condenser circulating water
It is recycled for cleaning system for recycling glueballs at outlet
