Description
Technical field
The present invention relates to field of papermaking, specifically a kind of no cabinet roll-type suction flat box.
Background technique
Suction flat box is the important equipment of paper machine, is widely used in the wet end and press section of paper machine, mainly uses
In to page dehydration or cleaning paper making felt.Main cabinet and vacuum tank panel composition, cabinet is a top surface axial aperture
Container is fixed in paper machine rack, and cabinet is connected to vacuum line, and wear-resistant material is installed in box top axial aperture and is manufactured
Vacuum tank panel, vacuum tank panel surface contacts with paper making felt, there is vacuum pumping channel in panel, aspirates from page
Or the steam in net blanket, to achieve the purpose that page dehydration or cleaning net blanket.
In normal production, the net blanket of paper machine is in high-speed cruising state, the negative-pressure adsorption that paper making felt passes through vacuum tank
Effect is adsorbed on vacuum tank panel surface, face under certain pressure and face contact always between vacuum tank panel and paper making felt
Sliding friction state, the sliding friction of this face and face contact can be lost net blanket and vacuum tank panel, reduce net blanket and vacuum
The service life of case panel, the power consumption for also resulting in the operation of net blanket are larger.
Summary of the invention
In order to extend the service life of net blanket, reduce the power consumption of net blanket operation, it is true that the present invention provides a kind of no cabinet roll-type
Suction water tank, the water suction box structure is simple, and friction when operation between paper making felt is small, power consumption is low, paper making felt
Service life can be extended.
The technical solution adopted by the present invention to solve the technical problems is: the present invention is mainly filled by guide roller set, axial seal
It sets, end face seal, support composition, guide roller set, axial sealer and end face seal are all installed on the support, and guide roller set is by least
Two deflector roll compositions being parallel to each other, the deflector roll of guide roller set is vacuum guide roller, mainly by being uniformly distributed the shell of suction hole, aspirating
Case, bearing support assembly composition, suction box are installed inside housings, and suction box is contacted by sealing strip and inner walls, shell
The axial ends of suction box is supported on by bearing support assembly.Axial sealer is mainly by sealing strip seat and sealing strip group
At axial sealer is fixed on the support by seal receptacle axial ends, and the seal receptacle and sealing strip of gland seal device are all long
Bar part, sealing strip are mounted on seal receptacle, and sealing strip and seal receptacle pass through axial pivot structure connection or sliding groove structure
It is coupled, the roll surface contact of the sealing surface and deflector roll of sealing strip, aspirates lower box part axis in the position of gland seal device sealing strip and deflector roll
It is corresponding to the position of sealing strip.The end for the axial space that end face seal is formed between adjacent two deflector roll shells, axis
To the lower section of intermediate axial position of the sealing device between adjacent two deflector rolls, the axis of axial sealer and deflector roll
Axis is parallel, the roll surface contact of the sealing strip of axial sealer and adjacent two deflector rolls.
The invention has the advantages that the present invention does not have box part, structure is simple, and the present invention is carried out to paper making felt
When suction, the net blanket pressure of generation is aspirated by the bearing support of deflector roll, the surface linear speed of deflector roll is synchronous with net blanket, net blanket and deflector roll
There is no sliding friction between roll surface, thus be greatly reduced paper making felt abrasion, reduce because overcome net blanket and suction box surface it
Between sliding-frictional resistance and the power consumption that generates.
