Description
Technical field
Present invention relates particularly to a kind of advanced screen cylinders.
Background technology
Pressurized screen is the key equipment in paper-making pulping production, and screen cylinder is the heart of pressurized screen, the precision of screen cylinder screen slot again
It decides the quality of good slurry, what is used is all generally at present uniformly to cut tooth socket on the inside of the reinforcing ring that rolls of machinery then to insert
Enter rod to be welded, although also there is preferable performance, since the reinforcing ring rolled has during cutting tooth socket
Stress release is yielding, leads to screen cylinder entirety screen slot low precision, the good slurry slurry yield of screening is low, and the quality of paper cannot be guaranteed.
Invention content
In view of the above technical problems, the present invention provides a kind of advanced screen cylinder.
A kind of advanced screen cylinder includes several reinforcing rings of equidistant arrangement, is connected by pole between the reinforcing ring；Screen cylinder
Be provided at both ends with reinforcement flange；The both ends of pole item respectively with one of flange welding；
The reinforcing ring is made of the first rack ring, fixed ring and the second rack ring successively；The rack ring and the fixation
It is equipped with corresponding pin hole on ring, the connection of rack ring and fixed ring is realized by the resilient key being inserted in pin hole；The tooth
Ring interior annular is placed with tooth socket, and rod is inserted between the tooth socket of the first rack ring and the tooth socket of the second rack ring.
Preferably, the pole is also adapted to the rack ring and the pin hole in the fixed ring；The pole passes through rack
Ring and fixed ring pin hole realize the series connection between reinforcing ring.
Preferably, the rack ring divides rack head and the tail connection to form by several.
Preferably, described that the number of rack is divided to be four, each divide one end of rack to be equipped with tenon, the other end is equipped with and tenon
The mortise of head cooperation.
The present invention provides a kind of advanced screen cylinders, change the screen slot low precision of traditional screen cylinder, need the disadvantage of manual amendment
End, screen slot precision reach error ± 0.01mm, reduce hand labor intensity.Present invention sieve improves passing through in slurrying screening
Ability, good slurry slurry yield is high, and cleaner at paper paper, screen cylinder integral strength height is durable.

Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes.
Embodiment：
Shown in Fig. 1 to 4, a kind of advanced screen cylinder includes several reinforcing rings 1 of equidistant arrangement, passes through pole between the reinforcing ring 1
3 series connection；Flange 2 is reinforced in being provided at both ends with for screen cylinder；It is welded respectively with one of flange 2 at the both ends of pole 3；
The reinforcing ring 1 is made of the first rack ring 11, fixed ring 12 and the second rack ring 13 successively；The rack ring（11、
13）With corresponding pin hole 14 is equipped in the fixed ring 12, pass through the resilient key 15 that is inserted in pin hole 14 and realize rack ring
（11、13）With the connection of fixed ring 12；The rack ring（11、13）Interior annular is placed with tooth socket 16, the first rack ring 11
It is inserted with rod 17 between tooth socket 16 and the tooth socket 16 of the second rack ring 13.
The pole 3 is also adapted to the rack ring and the pin hole 14 in the fixed ring 12.The pole 3 passes through rack ring
（11、13）And the cooperation pin hole 14 of fixed ring 12 realizes the series connection between reinforcing ring 1.
The rack ring（11、13）It is made of 4 points of rack head and the tail connections.Each one end for dividing rack is equipped with tenon 18,
The other end is equipped with the mortise 19 coordinated with tenon 18.
Implementation principle:The technical issues of mainly solving to increase the durable tolerance of screen cylinder while improving the screen slot uniformity,
The sector that tooth socket 16 is cut including multiple inner circles divides rack, divides the both ends of rack to cut out the tenon 18 that male and female coordinates each other in sector
With mortise 19, while several pin holes 14 are evenly distributed on dividing rack, it is each using Tenon to cooperatively form diameter by four points of racks
Different rack ring（11、13）, then by the first rack ring 11, fixed ring 12 and the second rack ring 13 bullet is used by reserved pin hole 14
Property pin 15 form a complete screen cylinder reinforcing ring 1, by 1 spaced equidistant arrangement of several reinforcing rings, installation shape in tooth socket 16
Then the rod 17 that shape is consistent with tooth form uses pole 3 will be each by automatic argon arc welder by rod 17 and 1 firm welding of reinforcing ring
A reinforcing ring 1 is connected, and flange 2 is respectively welded in 3 both ends of pole；
Reinforcing ring 1 is made of the first rack ring 11, fixed ring 12 and the second rack ring 13, is attached using resilient key 15,
When expanding with heat and contract with cold, its own can correct the stress release caused by expanding with heat and contract with cold, and avoid malformation.
The present invention provides a kind of advanced screen cylinders, change the screen slot low precision of traditional screen cylinder, need the disadvantage of manual amendment
End, screen slot precision reach error ± 0.01mm, reduce hand labor intensity.Present invention sieve improves passing through in slurrying screening
Ability, good slurry slurry yield is high, and cleaner at paper paper, screen cylinder integral strength height is durable.
Various modifications to these embodiments will be apparent to those skilled in the art, herein
Defined General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.
