Description
Technical field
It the utility model is related to paper making equipment field, more particularly to dewatering box.
Background technology
Papermaking is highly energy-consuming trade, and the major part of its energy consumption is to be used for steam drying.In paper making process, such as
The dehydration of fruit reinforcement screen cloth can then be effectively saved the consumption of steam.Traditional screen cloth dehydration is taken off using individual layer dewatering net
Water, this net elongation is high, and normal net deformation is big, and dehydration is uneven, causes white water consistency big, paper evenness is poor, and Paper Moisture is inclined
It is poor big.And existing dewatering box, much using control manually, automaticity is low, low precision, and the manpower and materials of consumption are larger.
Therefore, how existing dewatering box is improved makes it overcome above mentioned problem, be those skilled in the art urgently
The problem solved.
Utility model content
Main purpose of the present utility model is that providing one kind can automatically control, and dehydrating effect is good, and service life length takes off
Water tank.
To achieve the above objectives, the technical solution adopted in the utility model is：A kind of dewatering box, it is characterised in that：Including
Casing, lower dewatering net, upper dewatering net, drainpipe and grout outlet；The lower dewatering net is arranged above the casing, described de-
The network of rivers is covered on the lower dewatering net, and lower dehydration groove is offered on the lower dewatering net, is offered on the upper dewatering net
Groove is dehydrated, the lower dehydration groove corresponds to the upper dehydration groove and connects setting, and the upper dehydration groove includes oblique flow section and direct current section,
The oblique flow section opening large outlet is small, and the direct current section connects the oblique flow section outlet, and the width of the lower dehydration groove is not more than
The width of the direct current section；The casing includes more sub- casings, and the sub- casing does not connect mutually, and every sub- casing is correspondingly set
It is equipped with the drainpipe and the grout outlet；Slurry passes through the upper dewatering net and lower dewatering net, into the sub- casing, passes through
Collection slurry processes are dehydrated, and the slurry after dehydration flows out from the grout outlet, and moisture flows out from the drainpipe.
As an improvement, the dewatering box also includes control valve and flowmeter, go out described in the control valve connection each
Slurry pipe, the flowmeter are arranged on each grout outlet；The control valve and the flowmeter cooperatively form automation
Configuration system.
Preferably, the drainpipe is arranged at the sub- wall box, the grout outlet is arranged at the sub- casing bottom
Portion.
Further preferably, the upper dewatering net is made of polythene material.
Compared with prior art, the utility model has the advantage of：1st, the double-deck setting of lower dewatering net and upper dewatering net, takes off
Water is more uniform, and paper evenness is more preferable；And the setting of oblique flow section, slurry is smoothly entered upper dehydration groove, reduce slurry to upper
The impact of dewatering net, reduce the possibility of its deformation；Direct current section width can reduce slurry not less than the setting of lower dehydration well width
The impact of more lower dewatering nets so that lower dewatering net need not be changed substantially；In addition, upper dewatering net is made of polythene material,
So that it has certain elastic deformation, its generation is avoided not return the deformation of reverse, while polythene material cost is low, manufacturer
Just.2nd, using control valve and the automatic configuration system of flowmeter so that dehydration control can realize shaping overall process slurry network speed
Poor balanced, effectively control shapes the anisotropy of paper industry.3rd, collection slurry processes dewatering system is crossed so that the final water content of slurry reaches
24%-28%, reach making sheet requirement, can adapt to the conversion of different paper kinds, improve formation of sheet.4th, it is independent due to sub- casing
Set, the dehydration of flow, independent control drainpipe such as can automate according to the observing and controlling of flowmeter, so as to be adjusted to paper shaping
And evenness.
