Between size and shape be adjusted.
Preferably, a pipeline 22 is connected in each suction nozzle, multiple pipelines 22 are connected to a general pipeline, general pipeline
Both ends be respectively connected with moisture separation device and vacuum blower.This design can effectively aspirate the high speed near sandwich layer later roller
Air-flow, so that the surface layer air-flow from lowermost position be made preferably to run along slurry with the bottom air-flow for coming from above position
Direction merge compound, which reduces the disturbances of air-flow herein.
Cabinet 21 includes top plate 211, bottom plate 212, backboard 213 and two side plates, and there are a side openings.Top plate 211 with
Bottom plate 212 is oppositely arranged, backboard 213 cabinet 21 length direction connection top plate 211 and bottom plate 212 one side edge, and with
Suction intake 215 is oppositely arranged.Two side plates are set to the both ends of top plate 211 Yu bottom plate 212 in the length direction of cabinet 21, and
Top plate 211, bottom plate 212 and side plate are connected, to form suction chamber 214.Preferably, length of two side plates perpendicular to cabinet 21
Direction.It is formed with suction nozzle on top plate 211, bottom plate 212 is far from being provided with heating device 25 on a side surface of top plate 211.
Top plate 211 is formed with top baffle 216 on the side far from backboard 213.Top baffle 216 by top plate 211 side
Extend at edge to the direction far from bottom plate 212, and is vertically arranged with top plate 211.The top baffle 216 of right angle moulding designs, this
The liquid that sample can be such that baffle outer surface collects can be taken away in time after drippage.Top plate 211 is towards on a side surface of bottom plate 212
It is provided with air door orifice plate 217.Air door orifice plate 217 is tilted towards backboard 213, is spaced and is arranged with bottom plate 212, to form suction intake
215.Preferably, multiple through-holes are formed on air door orifice plate 217.Suction intensity in order to guarantee suction intake 215 is uniform, suction
The height of entrance 215 is incremented by design from both side ends to middle position.It specifically, is by the fore side of steam collection device 20
It is incremented by design with east side both side ends Xiang Zhongjia peace position is passed.For example, the height of suction intake 215 is in both side ends
16mm, at middle position, the height of suction intake 215 is 36mm.Preferably, air door orifice plate 217 is welded on the top plate of cabinet 21
On 211.
Bottom plate 212 is formed with lip 218 on the side far from backboard 213.Lip 218 is from the edge of bottom plate 212 to separate
The direction of top plate 211 extends, and forms obtuse angle between bottom plate 212.Preferably, on the direction far from backboard 213, bottom plate
212 length is greater than the length of top plate 211, so that the position of lip 218 is provided projectingly relative to top baffle 216, avoids
The dropping liquid that top baffle 216 drips falls into running screen cloth.
Heating device 25 includes steam-heating pipe 251 and warm water heating tube 252, and steam-heating pipe 251 and warm water heat
Pipe 252 is spaced apart from each other setting.The operating condition that warm water heating tube 252 is used to spray in starch provides warm water heating, steam to cabinet 21
The operating condition that heating tube 251 is used to spray in non-starch provides steam heating to cabinet 21, and wherein the temperature of warm water heating, which is lower than, forms sediment
The gelatinization point of powder.Preferably, warm water heating tube 252 is square tube, and steam-heating pipe 251 is round tube.
Thermally conductive polishing plate 26 cooperatively forms the space for accommodating heating device 25 with bottom plate 212, and steam-heating pipe 251 is round tube
And at least with bottom plate 212 keep interval setting, warm water heating tube 252 be square tube and respectively with bottom plate 212 and thermally conductive polishing plate 26
Contact setting.
The original intention of such design is: under the operating condition for the starch spray that do not come into operation, enabling steam-heating pipe 251, steam heating
There are the gaps of 2mm with bottom plate 212 on design position for pipe 251, do not contradict directly, therefore will not be excessively high due to vapor (steam) temperature
And the phenomenon that causing bottom plate 212 to heat unevenly, generating hot-spot.Under the operating condition for the starch spray that comes into operation, deactivated steam adds
Heat pipe 251 uses warm water heating tube 252 instead, and warm water is provided by autonomous system, it is ensured that water temperature is accurately controlled in 50 DEG C or so, is lower than 60
℃.In view of warm water temperature is not high, the warm water heating tube 252 for the warm water that circulates directly is contacted with bottom plate 212 on design position,
Square tube design is contacted to the greatest extent with bottom surface for warm water tube to ensure the uniform of heating.Meanwhile this warm water temperature was both
It can guarantee the demand of heating, and will not make starch gelatinization (starch will be gelatinized at 60~70 DEG C) that can thus form sediment
The drip tray bottom surface for being exposed to recombination region overhead is obtained effectively under different working conditions when powder spray comes into operation or do not come into operation
Heating, to prevent the condensate drop of water vapour, starch granules or slurry suspension object.
Preferably, lip 218 and thermally conductive 26 junction of polishing plate are in 30 degree of angles, and outside carries out polishing grinding processing, so that
It is detached in time under the action of the moisture on 218 surface of lip is in suction airstream along lip 218, without on 218 surface of lip
Form dropping liquid.
In the above-described embodiment, steam collection device 20 can be coated on the outer surface micron-sized does not glue micro- painting
Layer, so that 20 bottom surface of steam collection device and side have the distribution of relatively uniform micropore and lower surface tension, thus really
Water conservation 20 bottom surface of vapour collection device and cornice side are not easy to adhere to dirty particles or drop slurry under recombination region complexity stream conditions.
Preferably, it is stainless steel SS316L material that steam collection device 20 is whole, it is ensured that in the damp and hot chemical environment of wet end
Under it is not perishable.
By the above-mentioned means, starch granules, pulp particle and the water mist etc. that are drifted around capable of preferably drawing, and two
The different heating method of kind can preferably prevent the condensations such as starch granules to be slurried, therefore can reduce what drip tray frequently occurred
Slurry problem is dripped, the operating status of paper machine equipment and the quality of product are improved.
The beneficial effects of the present invention are: being in contrast to the prior art, the steam of web part of paper machine of the invention collects dress
Set and designed using vacuum pumping-type, can actively draw around starch granules, pulp particle and the water mist etc. that drift, be no longer by
Dynamic accept, therefore can be good at preventing these particles or water mist etc. from drifting everywhere, and at the outside bottom of cabinet
Portion is provided with heating device, and the condensations such as starch granules is further prevented to be slurried, therefore can reduce the drop that drip tray frequently occurs
Slurry problem improves the operating status of paper machine equipment and the quality of product.
Mode the above is only the implementation of the present invention is not intended to limit the scope of the invention, all to utilize this
Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content, it is relevant to be applied directly or indirectly in other
Technical field is included within the scope of the present invention.
