Description
Technical Field
The utility model discloses the paper machine field, concretely relates to vacuum roll sealing strip and sealed water saving fixtures.
Background
In standard configurations of paper machines, there are typically a variety of roll-type components, such as: a web guide roll, a blanket guide roll, a spreader roll, a curved roll, a paper guide roll, a vacuum roll, a calender roll, etc. The different types of rolls have different functions, mainly for support, running of the forming clothing, spreading of the paper web, dewatering and transfer of the paper web. Among the roller parts, the vacuum roll is a key part with a complex structure and the highest operation requirement. Vacuum rolls are generally classified into a couch roll, a suction transfer roll, and a suction press roll. The design principle of different types of vacuum rolls is completely the same. The roller body is a cylinder made of stainless steel, a plurality of small holes are drilled in the roller shell, a vacuum box is arranged in the roller shell of the paper web working section, and the vacuum box and the inner side of the roller wall are sealed by a sealing strip made of HDPE or graphite rubber. The vacuum zone of the vacuum roll continuously draws off the wet web of paper as the paper machine operates.
Fig. 1 is a schematic view showing a structure of a conventional sealing tape 10, and the conventional sealing tape 10 is a rectangular parallelepiped. Fig. 2 is a schematic diagram of the traditional sealing strip installed on the sealing strip support, a second U-shaped groove 14 is formed in the top of the sealing strip support 5, a pressurized air tire 7 is installed on the lower portion of the traditional sealing strip 10, and the pressurized air tire 7 is installed at the bottom of the second U-shaped groove 14 of the sealing strip support 5. Fig. 3 is a schematic diagram of a using state that a traditional sealing strip is installed in a vacuum chamber, the traditional sealing strip 10 is attached to the inner wall of a roller shell 9 of the vacuum roller, a sealing strip support 5 is installed inside a vacuum dehydration chamber 12 through a vacuum box wall plate 13, and a water spray pipe 8 is arranged inside the vacuum dehydration chamber 12. The working mode is as follows: inside hose and the 8 intercommunications of spray pipe of vacuum roll, lubricated water (running water) flows to spray pipe 8 through the inside hose flow direction of vacuum roll, last to traditional sealing strip 10 water spray infiltration traditional sealing strip 10 by spray pipe 8 again, under the effect of pressurized air child 7, traditional sealing strip 10 tightly laminates at vacuum roll roller shell 9 inner wall, traditional sealing strip 10 is in friction state all the time when vacuum roll roller shell 9 is rotatory, water on the traditional sealing strip 10 lasts the vacuum and takes away along vacuum roll roller hole 91 in vacuum dehydration room 12, so the abundant lubrication of sealing strip is vital to the paper machine operation. Because the lubrication of the traditional sealing strip 10 depends on the external spray pipe 8 as shown in figure 3, when the water nozzle of the spray pipe 8 is blocked or the running speed of the paper machine is higher, the traditional sealing strip 10 can aggravate the abrasion of the vacuum roller shell 9 or aggravate the local temperature of the vacuum roller shell 9 too high due to insufficient lubrication degree, and the risk that the paper machine cannot run normally is increased. And when the external spray pipe 8 sprays water, the friction surfaces of the traditional sealing strips and the inner wall of the vacuum roller shell 9 are not uniformly wetted.
The traditional sealing strip needs to be replaced after being used for about 1 year, and the short service life of the traditional sealing strip also increases the probability of damage to the vacuum roll.
