Description

Flow spoiler

Technical field

The present invention relates to a kind of flow spoiler, especially a kind of flow spoiler that forms water ring for overcoming high-speed paper machine condensate water in drying cylinder, belongs to papermaking equipment technical field.

Background technology

The flow spoiler water ring that can make to condense produces vibration, thereby can obtain very strong turbulent flow; Meanwhile, flow spoiler also can be divided into drying cylinder inwall the lattice storehouse much opening wide, and condensate water is directed to axial flow by flow spoiler and enters the cylinder end siphon pipe that is fixed and discharge, and there will not be the water ring with cylinder rotation.Use flow spoiler to compare with the rotation siphon pipe drainage arrangement of unconfined flow device with stationary siphon drainage arrangement, drying capacity can improve 30% left and right.

There is following defect in the flow spoiler that < < pulp and paper industry machinery and equipment > > " China Light Industry Press " mention in the third edition in June, 2011: (1) longeron eave tile place does not strengthen, in tensioner process, easily produce strain, the compression that siphon device crossbeam is subject to is large not, and the frictional force producing between casing wall is large not, easily produce potential safety hazard; (2) other a set of siphon device needs the latch of up to a hundred longitudinal beam connecteds and crossbeam, and because the deviation plug-in mounting latch of crossbeam longeron position can be required great effort very much, omits installment work under environment bring very large workload to evil in drying cylinder.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of flow spoiler is provided, rational in infrastructure, functional, safe and reliable, long service life.

According to technical scheme provided by the invention, a kind of flow spoiler, two annulus that comprise both ends overlap and the annulus cover between both ends annulus cover, and the annulus cover at both ends is connected by crossbeam with middle annulus cover, and crossbeam is uniformly distributed a plurality of along the circumferencial direction of annulus cover; Feature is: on the outer circumference surface of described annulus cover, a plurality of pan head screws are evenly set, the diameter of pan head screw end coiled hair is greater than the diameter of pan head screw; On described crossbeam, be provided with and a plurality ofly put with annulus the through hole that pan head screw matches respectively, crossbeam is hung on pan head screw by through hole.

Described annulus cover is formed by connecting by three arc longeron components, and longeron component connects by the screw rod of end, and the first stretching nut is set in one end of screw rod, at the other end of screw rod, the second stretching nut and the 3rd stretching nut is set.

Stiffener is welded respectively in both sides in described longeron component end.

Compared with the prior art the present invention has following advantage: in (1) flow spoiler of the present invention, the two sides, termination that form the longeron component of annulus cover are all welded with stiffener, have guaranteed that arc longeron component can bear larger clamping force; (2) longeron component of the present invention end is provided with pan head screw, and the top of pan head screw is provided with plush copper, and the pan head screw crossbeam that directly hangs tag, does not need latch plug-in mounting; The structure of having simplified flow spoiler, has reduced number of fitting parts, has reduced installation labour intensity, has improved the security reliability of using; (3) the easy standardization of structural design of the present invention, seriation, can be according to the needs of user's drying cylinder fabric width and strain, as long as change part of crossbeam, just can change the topology requirement that many moneys meet user; (4) crossbeam of flow spoiler of the present invention uniform punching on rectangle stainless steel pipe surface, buckles conveniently anticorrosion antiwear with longeron component; (5) the present invention has reduced workman's installation strength, and shortened downtime, reduced customer using cost.

The specific embodiment

Below in conjunction with concrete accompanying drawing, the invention will be further described.

As shown in Fig. 1～Fig. 6: as described in flow spoiler comprise annulus cover 1, crossbeam 2, screw rod 3, the first stretching nut 4-1, the second stretching nut 4-2, the 3rd stretching nut 4-3, pan head screw 5, stiffener 6, longeron component 7, through hole 8 etc.

As shown in Figure 1 and Figure 2, the present invention includes two annulus covers 1 at both ends and overlap two annulus covers 1 between 1 at both ends annulus, the annulus cover 1 at both ends is connected by crossbeam 2 with two middle annulus covers 1, and crossbeam 2 is uniformly distributed a plurality of along the circumferencial direction of annulus cover 1;

As shown in Figure 3, described annulus cover 1 is formed by connecting by three arc longeron components 7; As shown in Figure 4, described longeron component 7 connects by the screw rod 3 of end, and the first stretching nut 4-1 is set in one end of screw rod 3, at the other end of screw rod 3, the second stretching nut 4-2 and the 3rd stretching nut 4-3 is set;

As shown in Figure 4, a plurality of pan head screws 5 are evenly set on the outer circumference surface of described longeron component 7, the diameter of pan head screw 5 end coiled hairs is greater than the diameter of pan head screw 5; As shown in Figure 5, Figure 6, be provided with a plurality of through holes 8 that match with pan head screw 5 on annulus cover 1 respectively on described crossbeam 2, crossbeam 2 is hung on pan head screw 5 by through hole 2;

As shown in Figure 5, in the both sides of described longeron component 7 ends, weld respectively stiffener 6, guaranteed that arc longeron component can bear larger clamping force.

The mounting means of flow spoiler of the present invention: adopt three arc longeron components 7, on the circle of same cross section, by three screw rods 3, three longeron components 7 are connected into a full circle ring set 1,6 or 7 (being determined by cylinder diameter size) pan head screws 5 on each longeron component 7, have along the circumferential direction been evenly arranged, the diameter of pan head screw 5 end coiled hairs is greater than the diameter of pan head screw 5, pan head screw 5, for the crossbeam 2 that directly hangs tag, does not need latch plug-in mounting; At drying cylinder two ends, connect two groups of annulus cover 1, these two annulus covers 1 first needn't stretching; Corresponding pan head screw 5 on the annulus cover 1 at two through holes 8 at two ends on flow spoiler crossbeam and two ends is hung tag (guaranteeing that crossbeam is level), and mounting of one one, crossbeam, the blank of flow spoiler becomes; Adopt again longeron component 7 to be assembled into middle annulus cover 1, flow spoiler is shaped like this, next the 3rd stretching nut 4-3 is made to the diameter swell of annulus cover 1 to the outer end back-out promotion longeron component 7 of screw rod 3, extruding crossbeam 2 is close to drying cylinder inner surface, when all longeron components 7 all stretching crossbeam 2, and during correct position, the second stretching nut 4-2 and the 3rd stretching nut 4-3 are spouted extremely mutually, flow spoiler has formed the firm body of squirrel-cage frame structure together with drying cylinder inner surface, well flow-disturbing, improves steam heat efficiency.
