Description
Technical field
The present invention relates to heat exchanger tube technical field, the extruding cleaning device of especially a kind of heat exchanger tube.
Background technique
The cleaning way of Tube Sheet of Heat Exchanger includes physical cleaning, and chemical cleaning, ultrasonic cleaning etc., physics is clear in the prior art
Tube wall is scrubbed by brush in the mode washed, is easy to mark trace in this way, and by the way that spoiler, such as bullet are arranged in pipe
The mode of spring, cleaning it is ineffective；It exists in the prior art in the way of squeezing, so that the dirt and tube body in pipe are pressurized
Separation, so that the cleaning way for cleaning out dirt in pipe is realized, in CN105066748A, by the way that tube body is arranged to bullet
Property deformable material, by being passed through the different fluid of pressure, so that tube body compression distending or contraction, to reach dirt disengaging
Effect；Such cleaning way can effectively take out stains, however the requirement for tube body is more harsh, and tube body material needs
Be it is deformable in a certain range, deform it is more obvious, for the tube body of Light deformation material, only by being passed through pressure not cocurrent flow
Body causes stress difference, and effect is poor.Additionally, there are being squeezed using pressurizing unit tube body, thus detergency, such as
It in CN207703075U, by the cylinder pressure of transverse and longitudinal, applies pressure on plate, then be transmitted on pipe, to realize detergency, in this way
Mode although can be applied to the slightly hard pipe of material, squeezed however, this cleaning device needs to dismantle down heat exchanger tube
Cleaning.Pipe for welded type is simultaneously impracticable, and mode of its cleaning is relatively simple, is only able to achieve and squeezes along pipe is circumferential
Pressure, cleaning way is single, and effect is not obvious.

One end connects connecting rod 3, and the other end connects handle 5, connecting rod 3 and mobile jib 4 and realizes connection, connecting rod 3 one by hinge joint A9
Pawl 2 is cleaned by hinge joint B connection in end, and the other end connects mobile jib 4；Cleaning pawl includes cleaning pawl axis 7, idler wheel 8, pushing block 11, limit
Position tooth 12, ball 14, hinge joint C, left handle 16；Cleaning pawl axis 7 is arc, and left and right two is oppositely arranged, and cleaning 7 one end of pawl axis is
Connection handle, two cleaning pawl axis of left and right respectively correspond left and right handle, are provided with hinge joint at left and right handle and cleaning pawl axis connection position
C15, side is provided with sliding groove in left handle, and pushing block 11 is arranged in sliding groove, is equipped with limiting tooth 12 with sliding groove, pushes away
Block 11 can slide in sliding groove, and be limited by limiting tooth；Right handle 10 and sliding slot corresponding position are arranged to inclined-plane, and pushing block 11 exists
It during being slided up and down along sliding slot, corresponding with inclined-plane can support, so that right handle be pushed to turn in hinge joint C a certain range
It is dynamic；Spring is provided between connecting rod 3；Idler wheel 8 is arranged on cleaning pawl axis 7, idler wheel 8 can be rotated by axis of pawl axis.
Limiting tooth is triangle pawl shape, can stretch out and retract along the direction vertical with left and right handle, realize limit.
One end of left and right handle is arranged with external member 17, and external member 17 is made of elastic deformable material, and left and right bar is enabled to protect
It holds in certain position.
Ball 14 is provided between the every adjacent idler wheel 8 of left and right handle.
Driving device 5 is hydraulic cylinder, one of cylinder.
Fastener 18 is provided in connecting rod, fastener is realized left and right connecting rod buckle and fastened, when cleaning device is realized
When rotation squeezes cleaning, left and right fastener is snapped together, realizes the connection of left and right connecting rod, driving device 5 pushes connecting rod
It realizes to rotate around pipe axis and squeeze.
Cleaning pawl axis 7 is hollow shaft, and elastic plate 19 is provided in hollow shaft, and moving member 20 rotates fixing axle 21, protrusion
22, position corresponding with ball is provided with and is rolled to the hole that size matches on axis, and the ball 14 being arranged in axis can be along diameter
It stretches to out of described hole, each ball is both provided with rotation fixing axle 21, and rotation fixing axle 21 is installed by fixing piece 23
On the side of elastic plate 19, ball can be rotated around axis 21, and the other side and the moving member 20 of elastic plate 19 are oppositely arranged；
Moving member 20 is interval setting multiple raised 22.
Moving member 20 is strip, can be slided along the inner cavity of cleaning pawl axis 7,20 one end of moving member is connected with control
Product 24, control piece 24 are arranged in the opening of left handle and right handle, by sliding up and down control piece 24, enable to moving member 20
It is slided in inner cavity.
By controlling control piece 24, so that moving member 20 is slided in inner cavity, elastic plate 19 is withstood in convex 22 on moving member, when
When being moved to corresponding to ball position, due to top power effect, the ball 14 being mounted on elastic plate is extruded.
Preferably, limiting device is set on control piece 24, to control and keep the position of moving member 20.
After ball 14 pops up, when being limited the position of cleaning, it is farthest that vertical range of the farthest point from cleaning pawl is greater than idler wheel 8
Vertical range of the point from cleaning pawl can guarantee that ball 14 tightly suppresses pipe outer wall when circumferentially cleaning along pipe outer wall in this way, real
Now along the cleaning of pipe circumferential direction.
The course of work:
When cleaning device take compressed axially along pipe clean when, fastener 18 is opened, and connecting rod 3 can be with free-open-close, and by bullet
Spring 6 and actuator 5, which are realized, controls it along pipe outer shaft linear slide；2 sets of pawl will first be cleaned in pipe outer wall, and adjust pushing block 11
Position, thus during the position of adjustable claw, such as 11 slide downward of pushing block, since pushing block is to the inclined-plane in right handle 10
Pressure effect, right handle are to clamp shape, and sliding block, which continues to glide, to be adjusted, and the size until adapting to tube wall finally exists the close clamping of pawl
In pipe outer wall, the effect of limiting tooth locks position, cooperates external member 17, completes the installation to cleaning part.
Driving device 5, which pushes, to be pushed, 3 opening state of connecting rod, and the idler wheel 8 and tube wall cleaned on pawl is in close contact, and
Pipe outer wall is slided, and in sliding process, idler wheel 8 realizes extruding, the dirt of inside pipe wall to tube wall in certain pressure allowed band
It due to the effect of pressure, is detached from tube wall, realizes that the effect removed contamination, driving device 5 recycle, since spring acts on, connecting rod 3 is returned
It receives, executes opposite direction and squeeze cleaning, it is multiple that progress can be recycled.
When cleaning device takes targetedly part extruding cleaning, fastener 18 is fastened, and connecting rod 3 is packed up, driving dress
The downside for being mounted on mobile jib 4 is set, cleans 2 sets of pawl in pipe outer wall, and adjust the position of pushing block 11, thus the position of adjustable claw,
Tightness degree is slightly loose, and being subject to can guarantee that pipe fitting will not be moved significantly, can be adjusted according to the actual needs, at this moment,
Control piece 24 is adjusted, moves it in mounting groove, is ejected until observing dynamic ball 14, it is fixed with limit or locking device
The position of control piece 24.Position and the ball that this process needs to cooperate adjustment pushing block 11, control piece 24 to adjust adjustable claw
Position after being ejected guarantees that ball can be contacted closely with pipe outer wall, realizes the extruding cleaning of pipe circumferential direction, after being installed,
Driving device moves up and down, and enables cleaning pawl around pipe axis rotary squeezing, and in this course, ball 14 is rolled along axis 21
It is dynamic, and tube wall is squeezed, realize cleaning.
