Abstract
The utility model relates to a hot-air guide roll for a paper-making machine. The utility model comprises a rotary shaft and a hollow roll body arranged on the rotary shaft. The end face of the roll body is provided with a static seal plate which is provided with a circular arc-shaped through groove. The external end face of the static seal plate is provided with an air intake end head. The external side wall of the air intake end head is provided with a hot-air inlet. The position that the air intake end head is corresponding to the circular arc-shaped through groove of the static seal plate is provided with a hot-air outlet. The end surface of the middle of the roll body is provided with a wind-proof partition board. The outer wall of the roll body is distributed with rows of downwind boards at intervals along the axial direction, and the outer diameter of the downwind boards is same with the outer diameter of a movable seal plate. A cross wind board is fixedly connected between each downwind board in the ring gap of a movable seal sleeve and the roll body.
Description
The utility model relates to the hot blast deflector roll of paper machine.
The potential of at present a lot of paper machines is not all given full play of inadequately because of the ability of drying nest.Drying capacity improves at the group number that former oven dry portion increases drying cylinder in some enterprise, though the speed of a motor vehicle is obviously improved, cost is too high, is difficult for accepting.Also there are a lot of people directly the hot blast deflector roll to be improved, as CN1036808A disclosed " roller of paper machine or paper curing machine or cylinder ", this roller comprises a columnar roller shell and a fixed axis that is installed in the roller shell, a plurality of nozzles are housed on axle, have a hot-fluid inlet port on the end face of axle, hot-fluid enters axle by this mouth, gives the roller shell through nozzle to the inner cylinder face injection of hollow roll shell and with thermal energy transfer.To be its heat energy system be delivered to the roller outer surface by the inner cylinder face that acts on roll body to the shortcoming of this deflector roll more just acts on and treat dried paper web, and efficient is not high.
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, treats dried paper web and carries out evenly dry hot blast deflector roll for paper machine provides a kind of dryer felt that the directly even cloth of hot blast can be acted on.
The hot blast deflector roll of realizing the utility model purpose comprises rotating shaft and is installed in hollow roll body in the rotating shaft, the end face of described roll body is provided with a static seal plate that has an arc-shaped slot pass, be provided with an air intake termination in the outer face of static seal plate, on the lateral wall of air intake termination, have a hot blast import, have a hot-blast outlet in the relative position of the arc-shaped slot pass with the static seal plate of air intake termination, on the endface position of the middle part of roll body, be provided with a wind blocker, in the outer wall upper edge of roll body axial distribution number its external diameter of row downwind plate of distributing alternately identical with the external diameter of movable sealing plate arranged, be connected with a beam wind plate between each downwind plate in the annular space between movable sealing sleeve and roll body.Dryer felt is overlapped on the movable sealing sleeve of roll body and the downwind plate and drags roll body and rotates with respect to the static seal plate during work, hot blast enters respectively in the different wind district that is separated into by beam wind plate, movable sealing sleeve inwall and deep bead by the arc-shaped slot pass on the static seal plate from motionless air intake termination, blows to dryer felt and play the oven dry effect under the guiding of downwind plate.
Be to guarantee the sealing property between movable sealing sleeve and the static seal plate, can between sealing shroud and static seal plate, be provided with one by toroidal cavity, the corresponding maze-type structure that round ring boss constituted that is located on the movable sealing sleeve end concentric that are located on the static seal plate end face with rotating shaft.
The downwind plate that described downwind plate can be designed to a rectangular tubular connects dryer felt to be of value to holder.
The utility model compared with prior art has following advantage:
1. by being set, beam wind plate, downwind plate and wind blocker constituted many air channel structures different in size, that do not wait apart from rotating shaft centre distance, hot blast is blown out from radially exporting through axial ducts, both the hot blast subregion was imported, can regulate the ventilation that strengthens the deflector roll mid portion, thereby solved page mid portion slow evaporation, the fast inhomogeneous dry problem of both sides evaporation effectively, drying efficiency and quality all are improved;
2. forms external surface by the even roller of downwind plate, beam wind plate, wind blocker and becomes radial roll body, have in light weight, the rotation flexible characteristic, make dryer felt can drive its rotation easily, thereby can save the driving member in the driving-chain, make compact conformation, solve the rotation problem of roll body effectively.
3. the dryer felt that blows through of hot blast enters paper machine oven dry portion pocket type plenum area, evaporates the moisture on the dryer felt rapidly and increases the temperature in bag district, thereby improve the drying capacity of oven dry portion, and then can improve the speed of a motor vehicle of paper machine.On the other hand, the raising of the aridity of dryer felt also is of value to the service life of improving dryer felt;
4. easy for installation, can exchange fully with common dryer felt deflector roll and use and need not the paper machine is done any change.Be applicable to all kinds of paper machines.
Provide embodiment below in conjunction with accompanying drawing.But content of the present utility model is not limited in the content of present embodiment.
