Spoiler

Abstract

The invention relates to a spoiler which comprises two circular ring sleeves at both end parts and a circular ring sleeve positioned between the two end part circular ring sleeves. The two end part circular ring sleeves are connected with the middle circular ring sleeve by beams; and a plurality of beams are uniformly distributed along the peripheral directions of the circular ring sleeves. The spoiler is characterized in that a plurality of pan head screws are uniformly arranged on the outer peripheral surface of each circular ring sleeve; the diameter of a pan head at the end part of each pan head screw is greater than that of the pan head screw; each beam is provided with a plurality of through holes which are respectively matched with the pan head screws on the corresponding circular ring sleeve; the beams are hung on the pan head screws by the through holes; each circular ring sleeve is formed by connecting three arc longitudinal beam assemblies; the longitudinal beam assemblies are connected by screw rods at the end parts; one end of each screw rod is provided with a first supporting nut; and the other end of each screw rod is provided with a second supporting nut and a third supporting nut. According to the invention, inserted pins are not required for insertion in the installing process of the beams and the circular ring sleeves; the structure of the spoiler is simplified; the number of accessories is reduced; labor intensity of installation is reduced; and safety and reliability of use are improved.

Description

technical field [0001] The invention relates to a spoiler, in particular to a spoiler for overcoming the formation of a water ring in a drying cylinder by condensed water of a high-speed paper machine, and belongs to the technical field of papermaking machinery. Background technique [0002] The turbulence can make the condensate ring oscillate, so that a strong turbulent flow can be obtained; at the same time, the turbulence can also divide the inner wall of the drying cylinder into many open compartments, and the condensate is guided by the turbulence to flow axially The end entering the tank is discharged by a fixed siphon, and there will be no water ring that rotates with the tank. Compared with the rotary siphon drainage device without spoiler, the drying capacity can be increased by about 30% by using the spoiler and the fixed siphon drainage device.

AI Technical Summary

Problems solved by technology

[0003] The spoiler mentioned in the third edition of "Pulp and Paper Machinery and Equipment" "China Light Industry Press" in June 2011 has the following defects: (1) There is no reinforcement at the hook of the longitudinal beam. Elastic deformation occurs, the compression of the beam of the siphon is not strong enough, and the friction between the cylinder wall and the cylinder wall is not strong enough, which is easy to cause safety hazards; (2) Another set of siphon requires hundreds of pins connecting the longitudinal beam and the beam, Moreover, due to the deviation of the position of the beam and longitudinal beam, it will be very laborious to insert and insert the latch, which will bring a lot of workload to the installation work in the harsh environment in the dryer.
