Description

A kind of single dryer gluing thing removal device

Technical field

The utility model relates to a kind of device of removing the gluing thing of the dried net surface of single dryer drying equipment.

Background technology

In paper industry, the general mode of many group drying cylinder group heatings that adopts is carried out drying to the l Water Paper page or leaf.Along with improving constantly of paper machine speed, the time get lodged in the middle of the drying cylinder in order to reduce the page broken end, the pattern of single dryer has appearred in drying section.In front in several groups of drying cylinders, when page moisture is big, when intensity is low, dried net places the top of drying cylinder that page is close to dryer surface to carry out drying, if occur broken end in the production process, page will be fallen downstairs, and can not be blocked between the drying cylinder.Several groups of drying cylinders in back are then taked the mode of two-layer arrangement up and down, can effectively reduce the difference of paper smoothness for two sides like this.

Single dryer following row's drying cylinder of double drying cylinder originally replaces with vacuum furnace.The densely covered aperture in vacuum furnace surface relies on the suction of vacuum, and vacuum furnace can be taken page away effectively in the moist steam that last row's drying cylinder is evaporated, and improves the drying efficiency of drying section.In addition, vacuum action has also been offset the centrifugal force that vacuum furnace produces in running up, and paper web can be close to be done on the net, and unstable degree reduces, and the broken end number of times reduces, thereby has improved the operational efficiency of drying section.

At present, this pattern of single dryer has obtained widespread usage in high-speed paper machine.At home, simple with the wood pulp be raw material the paper mill seldom, all use waste paper to be raw material mostly.Waste paper kind difference, the foreign material that it contained are also different.Most of impurity can both rely on screening and cleaning equipment to remove, though the gluing thing can still be remained in the slurry by granular in hot decentralized system.These gluing things are subjected to action of high temperature at drying section, and it is glutinous that deliquescing becomes, and is easy to adhere to the surface that the paper hair is bonded at dried net and drying cylinder.Along with the increase of paper machine operation time, these gluing things and paper hair are cumulative, and the air permeability that causes doing net descends, and dryer surface conducts heat uneven, not only influences into the water uniformity and the outward appearance of paper, and very easily cause production process to interrupt paper.

The utility model content

The utility model provides the gluing thing on a kind of effective removal drying cylinder and the dried net surface, has improved production efficiency and has reduced the single dryer gluing thing removal device of production cost.

In order to solve the problems of the technologies described above, the utility model adopts following scheme:

A kind of single dryer gluing thing removal device, comprise drying cylinder A1, the vacuum furnace B1, drying cylinder A2, vacuum furnace B2, drying cylinder A3, vacuum furnace B3, drying cylinder A4, deflector roll C1, idler roller, corrector roll and the deflector roll C2 that hold by dried net, the gluing thing is installed between deflector roll C1 and idler roller shifts deflector roll C3.On gluing thing transfer deflector roll C3, the doctor blade device of removing the gluing thing is installed also.

The utility model is by increasing a subsidiary deflector roll that doctor blade device is installed in the deflector roll of drying cylinder, effectively remove dryer surface and dried online gluing thing, keep doing the cleaning of net, reduce cleaning and do the frequency of net and the consumption of dried net cleaning agent, improve production efficiency, saved production cost.

Accompanying drawing 1 is the utility model master TV structure schematic diagram.

The specific embodiment

Understanding for the ease of those skilled in the art is further described the utility model below in conjunction with drawings and Examples:

As shown in Figure 1, a kind of single dryer gluing thing removal device, comprise drying cylinder A1, the vacuum furnace B1, drying cylinder A2, vacuum furnace B2, drying cylinder A3, vacuum furnace B3, drying cylinder A4, deflector roll C1, idler roller 1, corrector roll 2 and the deflector roll C2 that hold by dried net, gluing thing transfer deflector roll C3 is installed in deflector roll C1 and 1 of idler roller.On gluing thing transfer deflector roll C3, the doctor blade device 3 of removing the gluing thing is installed also.

In the actual moving process, the concrete pass order of doing net is: drying cylinder A1, vacuum furnace B1, drying cylinder A2, vacuum furnace B2, drying cylinder A3, vacuum furnace B3, drying cylinder A4, deflector roll C1, gluing thing shift deflector roll C3, idler roller 1, corrector roll 2, deflector roll C2.The page of coming when press section is during by one group of single dryer, page be in drying cylinder with do net between, be subjected to the dryer surface high temperature action, water evaporates is come out.Simultaneously, part gluing thing and paper hair stick to drying cylinder and the surface of doing net.Because drying cylinder itself is furnished with doctor blade device, thus the on-stream gluing thing that can get rid of the overwhelming majority, and the gluing thing of doing on the net front all can not be removed by drying cylinder and vacuum furnace the time.When dried network operation when the gluing thing shifts deflector roll C3, doing the net front contacts with gluing thing transfer deflector roll C3, do the just natural surface of transferring to gluing thing transfer deflector roll C3 of part gluing thing on the net front, shift the subsidiary doctor blade device of installing 3 of deflector roll C3 by the gluing thing then the gluing thing is removed.

Claims (2)

1. single dryer gluing thing removal device, comprise drying cylinder A1, the vacuum furnace B1, drying cylinder A2, vacuum furnace B2, drying cylinder A3, vacuum furnace B3, drying cylinder A4, deflector roll C1, idler roller (1), corrector roll (2) and the deflector roll C2 that hold by dried net, it is characterized in that: doing between deflector roll C1 and idler roller (1) is equipped with the gluing thing on the net and shifts deflector roll C3.

2. single dryer gluing thing removal device according to claim 1 is characterized in that: described gluing thing shifts on the deflector roll C3 doctor blade device (3) is installed.
