Specific embodiment
The utility model is further described below with attached drawing combined with specific embodiments below.
Embodiment
As shown in Figure 1 and Figure 2, the present embodiment a kind of high backfin of self-cleaning type move spray equipment, mainly include outer tube 1,
Spray tube 2, wig-wag 3 and tube brush device 5.
Wherein, outer tube 1 is used as support member, when in use, across the two sides for being mounted on press section of a paper machine, outer tube 1
Both ends outer pipe support 102 is installed, fixation is supported to outer tube 1 by outer pipe support 102.Herein, outer 102 knot of pipe support
Structure is as shown in Figure 7 comprising U-shaped card 104 and pedestal 105, pedestal 105 is used as installation foundation, is supported to outer tube 1, U-shaped
Outer tube 1 is then fastened on pedestal 105 by bolt by card 104.The middle position of outer tube 1 opens up a long slot hole 101, and
The length of long slot hole 101 is greater than the width of processed felt.
Spray tube 2 cleans felt for spraying water, and is actively plugged in outer tube 1, and in-between and both ends position
Installation support slipper 4 is set, is arranged in outer tube 1 by the support of support slipper 4, so that spray tube 2 can be along the axial shifting of outer tube 1
It is dynamic.One end of spray tube 2 has water inlet 202, and water inlet 202 installs pipe fitting, the evacuation that pipe fitting is opened up from outer tube 1
It is stretched out outside outer tube 1 in hole, external water source can be connected；The medium position of spray tube 2 opens up spray apertures, spray apertures and outer tube 1
On long slot hole 101 it is corresponding, the water sprayed from spray apertures may pass through long slot hole 101 and directive felt.It should be noted that spray
It drenches hole and one row is set along 2 length direction of spray tube, and the length of long slot hole 101 is greater than the total length of spray apertures, have swing empty
Between.Meanwhile nozzle 201 being installed in the spray apertures of spray tube 2, so that water column is concentrated, impact force is big, cleans more clean；And
And nozzle 201 uses ruby high pressure needle nozzle herein, has good wearability and impact resistance, diameter of spraying water
0.9mm, irrigation pressure meet felt cleaning demand up to 30bar.
Straight line of the spray tube 2 in outer tube 1, which swings back and forth, to be realized by wig-wag 3, and wig-wag 3 is mounted on outer tube
1 one end, and partially protrude into outer tube 1, it is connect with 202 one end of water inlet of spray tube 2, and wig-wag 3 passes through pin 8 and spray
The end of shower pipe 2 connects, easy disassembly；And position corresponding with pin 8 offers dismounting hole 103 on outer tube 1, convenient for tearing open for pin
Dress.Wig-wag 3 can be used oscillating oil cylinder, rotary actuator, oscillating motor etc. it is existing in relatively conventional equipment, as long as can be realized
The linear reciprocation of spray tube 2 is swung, and is not particularly limited.The reciprocally swinging movement that spray tube 2 is driven by wig-wag 3, can
The cleaning blind area between adjacent nozzle 201 is avoided, the continuous cleaning line free of discontinuities along felt wide cut direction is formed, felt can be made complete
Uniformly, page moisture is uniform for width washing, improves product quality.
In order to there was only linear reciprocation swing when the work of spray tube 2, without rotating, caused water spray position becomes
To change, in the present embodiment, support slipper 4 is mounted on spray tube 2, gib block 7 is equipped with by screw 6 on the inner wall of outer tube 1,
The guide groove matched with gib block 7 is offered on support slipper 4.By the cooperation of gib block 7 and 4 upper guide groove of support slipper, make
Obtaining spray tube 2, only straight line is swung back and forth, without rotating, guarantees that 201 water spraying direction of nozzle is constant, flushing is more concentrated.
The long-time service of spray tube 2 can be formed in the interior thereof dirt, and be easy on the inner wall for being adhered to spray tube 2,
It is easy plug nozzle 201, in order to which to preferable cleaning blowdown is carried out inside spray tube 2, the present embodiment is non-spray tube 2
202 one end of water inlet is installed by tube brush device 5.In conjunction with shown in Fig. 1, Fig. 2 and Fig. 6, tube brush device 5 includes brush holder 501, brush axis 502, bristle
503 and brush handle 505；Wherein, brush holder 501 is installed on the end of spray tube 2 by flange, and has sewage draining exit on brush holder 501
504, dirt in spray tube 2 can be discharged under the impact force of water；The support of brush axis 502 is arranged in brush holder 501, and passes through brush holder
In 501 insertion spray tubes 2, bristle 503 is distributed on the brush axis 502 in insertion spray tube 2；Brush axis 502 is arranged in brush handle 505
Outer end, rotation brush handle 505 can drive brush axis 502 to rotate.In order to play the role of preferable cleaning, axis of the bristle 503 along brush axis 502
It is distributed to Spiral distribution or along the radial arrays of brush axis 502；Herein, bristle 503 is distributed with along the carry out circumference array of brush axis 502
Three rows, bristle 503 are contacted with 2 inner wall of spray tube, can be by bristle 503 to adhering on 2 inner wall of spray tube when brush axis 502 rotates
Dirt is cleared up, and the dirt after cleaning is discharged from sewage draining exit 504 again, guarantees the cleannes inside spray tube 2, nozzle 201 is not
It is easy blocking.
In actual production, often the both sides of the edge of felt are easier to pollute, and will lead to wet web when serious and go out splenium and fall side
Phenomenon generates disconnected paper, for this purpose, the spray apertures on spray tube 2 open up a row along its length, and both ends distribution is closeer than intermediate distribution
Collection, felt edge relative intermediate position flushing frequency is higher, guarantees quality.
When specifically used, 30-50 DEG C of clear water is passed through spray tube 2 after high-pressure hydraulic pump pressurizes, through water inlet 202
It is interior, and water outlet pressure is sprayed up to the water column of 30bar from nozzle 201, while under the action of wig-wag 3,2 linear reciprocation of spray tube
It swings, high quality cleaning is carried out to felt.It swings back and forth by the way that wig-wag 3 is high-precision, excessively cleaning can be eliminated and leakage is clear
The phenomenon that washing cleans felt entire surface, the effective quality for improving paper and the service life for extending felt.If for a long time
When using causing nozzle 201 to block, spray tube 2 can be extracted out online and cleaned and replaced, greatly ensure that the stabilization of production
Property.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design
Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
