Description

Spray-propelling atomizer

The utility model relates to the atomising device with rotation vent component, relates in particular to by spraying and promotes the sprayer unit that vent component rotates.

Used traditional cooling tower of last a century, to ventilate and take away heat in the water with exhausting motor, fan blade,, in tower, be placed with a large amount of fillers in order to reach better cooling effect, the water droplet that allows water-locator plant changes moisture film, increases the contact area of wind and water.The patent No. is ZL90106170.0, denomination of invention for the Chinese invention patent of " spray-propelling atomizer " provides the spray-propelling atomizer of using on a kind of cooling tower of new generation, and it comprises and is installed in atomizer and a fan blade, spray propulsion body (feed liquor bindiny mechanism) on the hydroecium.The liquid that is come by pumping ejects and is atomized through atomizer, and produces back thrust, drives the rotation of hydroecium and fan blade, and the wind of generation makes atomized liquid obtain cooling.The spray propulsion body is used for supporting hydroecium, also connects feed tube and uses, and wherein is provided with bearing, lubricating oil and sealing device, makes tumbler and is not able to antifriction between the moving part with lubricated.But the applicant states in the practice of " spray-propelling atomizer " of ZL90106170.0 patent on the implementation, finds that it also exists the some shortcomings place, thereby can not become practical product.Accompanying drawing 1 is the feed liquor bindiny mechanism (being the spray propulsion body) of this spray-propelling atomizer, comes the simple declaration main weak point of this device once below in conjunction with this accompanying drawing 1.

The first, leakage of oil.Among Fig. 1 25,26 bearings are radial bearings of national standard, under turning cylinder 24 middling speed rotation status, the lubricating oil in the bearing is because of being subjected to the rotation heating, and viscosity diminishes, and under the gravity effect downward seepage, the taphole below the side of step 21 (not drawing among the figure) is drained.In the actual motion, lubricating oil just leaked to the greatest extent in about about three months.Just carry out dry friction behind the unlubricated oil in the bearing, and the liquid corrosion bearing that rushes over from sealing ring 27 is so that bearing rubs soon is bad, rust is dead.Among Fig. 1, the 23rd, top chock, the 22nd, top chock mounting flange.

The second, axial float causes the bearing abrasion and influences normal operation.Because there is axial float power in this spray-propelling atomizer when moving, and fluctuates along with the fluctuation of inlet hydraulic, and the common radial ball bearing among Fig. 1 is difficult to bear this axial float power, influences operate as normal so cause the bearing abrasion after the long-time running.

The purpose of this utility model is, improves at the above-mentioned deficiency of aforementioned existing spray propulsion, provides a kind of and can overcome these not enough spray-propelling atomizers.

The spray-propelling atomizer that the utility model provides, comprise hydroecium 1 and install thereon atomizer 2 and fan blade 3 and connecting mechanism for rotating 5 that feed tube and hydroecium 1 are coupled together, turning cylinder 4 is integral with said hydroecium 1 or affixed in this connecting mechanism for rotating 5, moving part and feed tube flange 11 are not affixed for they, in turning cylinder 4 and employing rolling bearing 6,7 antifriction between the moving part, at turning cylinder 4 and be connected in and be not provided with sealing device 8 between the moving part on the feed tube flange 11, it is characterized in that:

(1) in said connecting mechanism for rotating 5, an oil sealing nut 9 that is screwed into turning cylinder 4 lower ends is arranged, it compresses rolling bearing 6,7, there is a cylindrical shape part that makes progress in the outside of oil sealing nut 9, with rolling bearing 6 and 7 and supporting member be contained within wherein, the upper end of this cylindrical shape part flushes with the upper end of upper bearing (metal) 6 basically, is full of lubricating oil in the tube;

(2) bearing block 10 is arranged, comprise the inner cylinder part of block bearing 6,7 and the outer cylinder part of containing oil sealing nut 9, this outer cylinder part is connected on the liquid feeding disc 12 that is connected with feed tube flange 11 with bolt, has several side direction outages 13 around its bottom.

This spray-propelling atomizer that the utility model provides, overcome the aforesaid drawbacks in the existing device, because oil sealing nut 9 has been sealed the lubricating oil in the bearing and blocked the invasion of feed liquor, bearing can not damaged because of oil starvation or corrosion, guaranteed the life-span of bearing, evidence has improved 4-5 doubly than the life-span of the spray-propelling atomizer of aforementioned prior art.This has just improved social benefit (power plant, chemical plant, steel mill can not be shut down maintenance at ordinary times) and economic benefit.

Further describe this spray-propelling atomizer of the present utility model below in conjunction with accompanying drawing, each accompanying drawing is:

The connecting mechanism for rotating schematic diagram of the existing spray-propelling atomizer of Fig. 1;

The structure cutaway view of Fig. 2 preferred embodiment of the present utility model.

Among Fig. 2, the 1st, hydroecium, on revolve atomizer 2 be loaded on hydroecium 1 around, fan blade 3 is loaded on the lower flange of hydroecium 1, turning cylinder 4 is integrally welded with hydroecium 1.In order to bear the bi-directional axial load better, bearing 7 adopts the circular cone thrust bearing, and another bearing 6 adopts spherical rolling bearing.Certainly, also can all use the circular cone thrust bearing by bearing 6,7.Oil sealing nut 9 is screwed into from turning cylinder 4 lower ends with left hand thread, and two rolling bearings 6,7 are pressed on the step of hydroecium 1, and it has one bearing and supporting member thereof be contained within wherein cylinder, is full of lubricating oil in the letter.Hydroecium 1 oil sealing nut 9 with dextrorotation direction band and is rotated together, and like this, it is tight more that oil sealing nut 9 just changes more.For left-handed hydroecium, just use the oil sealing nut of right-handed thread.Certainly, also can lock the oil sealing nut with other method.Liquid feeding disc 12 usefulness bolts are connected with feed tube flange 11, are equiped with sealing device 8 between the outside, turning cylinder 4 lower ends and liquid feeding disc 12.The outer cylinder of bearing block 10 is fixed tightly on the liquid feeding disc 12, and its inner cylinder is used as the supporting base of bearing 6 and 7.Simultaneously, bearing block 10 also has an annular section that stretches on the bearing 6, and the felt circle 14 of a sealing usefulness is installed in the cannelure of this part, and is pressed on the turning cylinder 4.Because fan blade 3 makes between hydroecium 1 and the upper bearing (metal) top and forms negative pressure in the gap, fly ease from here in order to prevent the lubricating oil in the bearing, thereby set up felt circle 14.The installation dimension of the upper end of oil sealing nut 9 flushes with the upper end of upper bearing (metal) 6 basically, although under action of centrifugal force, the lubricating oil in 9 on the oil sealing nut has a small amount of flange and goes out, and it is too many can not fly ease.The outer cylinder of bearing block 10 has several side direction outages 13 around the bottom, passes feed liquor that sealing device 8 rushes out and the lubricating oil that comes that flies to overflow from oil sealing nut 9 tops is discharged from outage 13.
