Description
Technical field
The utility model relates to the boiler equipment technical field, especially relates to a kind of stuffing box gland that is used for exhaust heat boiler mechanical vibrator deashing device.
Background technique
In the hot flue gas of exhaust heat boiler, contain the amounts of dust particle; Therefore on boiler heating surface, assemble easily, the time forms a large amount of dust stratifications once long, has influenced the heat-transfer effect of boiler heating surface; Cause boiler output to descend; Generated energy reduces, and long-time dust stratification also can cause serious problems such as pipe break, and reducing therefore that boiler heating surface dust stratification problem just becomes basically the most also is one of problem that must solve.
In order to improve boiler thermal output; Realize boiler safety, stable operation; Generally need to arrange deashing device, the deashing device that uses on the exhaust heat boiler at present mainly contains: steam sootblower, acoustic wave soot blower, inflammable gas detonation soot blower and mechanical vibrator deashing device etc.What wherein the most often adopt is the mechanical vibrator deashing device, and it utilizes the small capacity motor as power, and the drive main shaft is done and slowly run, and on main shaft, arranges beater.Transferring power was given inner vibrating rod when beater impacted drive link, in the chien shih heating surface transverse vibration at a flash of bump, made the dust stratification that sticks above that produce small slight crack, was destroyed and came off up to the adhesion of dust stratification.Very high to dust burdening in the cement kiln tail kiln gas, the very fast characteristics of tube surface dust stratification speed, adopting the mechanical vibrator deashing is the ideal mode of effect and cost performance.
Since kiln tail kiln gas have negative pressure big (generally reach-5000pa ~-8000pa), in order to reduce radiation loss, boiler is to the high requirement that is sealed with of various pipeline parts through walls; Present various mechanical vibrator deashing devices be sealed with different forms, exist seal form to be not easy to locate but all concentrate, can not guarantee the perpendicularity of drive link; Distortion can not be proofreaied and correct greatly during welding, causes the rapping head of outside rapping apparatus can not be accurate during operation, very easily causes outside vibrating rod distortion, deficiency such as stuck; And because the rapping seal arrangement is fixing through welding; The weld bond One's name is legion, simple frock can't guarantee welding precision, more is difficult for guaranteeing the coaxality of drive link and interior vibrating rod; Cause the drive link fracture in the use, and almost can't reprocess.
The model utility content
The purpose of the utility model be to provide a kind of simple in structure, applied widely, be easy to production and assembly, have the very mechanical vibrator deashing device stuffing box gland of high performance-price ratio.
In order to achieve the above object; The utility model is realized through following technological scheme: a kind of stuffing box gland that is used for exhaust heat boiler mechanical vibrator deashing device, comprise sleeve, flange and seal ring, and the endoporus of its middle sleeve is a step hole; With the connecting end of flange be macropore; Its end face circumferentially is evenly equipped with and the attachment hole of flange screw one to one, and flange bottom connecting end is seated in the endoporus of sleeve, and is fixedly connected with sleeve through the bolt that is installed with spring washer.The lower end sealing surface of flange is an inner conical surface, realizes the sealing of sleeve and flange through being placed on seal ring on the endoporus step surface.On bolt, penetrate spring washer and guaranteed bolted tightness, and help the sealing of mechanism; Have shoulder hole on the sleeve, the location when being convenient to assemble, and can guarantee the perpendicularity that sleeve and sealing seat steel plate weld preferably; The lower end sealing surface of flange is an inner conical surface, when assembling, can play the effect of fastening seal ring, has guaranteed the sealability of stuffing box gland.
As optimization, the outside dimension of described flange bottom connecting end is convenient to the assembling of flange and sleeve, and is helped improving cooperate degree and concentricity is installed between the path size and big footpath size of sleeve step hole.
As preferably, described bolt is selected hexagon socket head cap screw for use, has guaranteed the smooth of rear flange surface is installed, and chooses more conveniently and economical, and helps the location and changes.
Compared with prior art, the beneficial effect of the utility model is:
1, simplified number of spare parts, and bolt is standard piece, is beneficial to the location and changes;
2, optimized processing technology, each part is at first considered centrosymmetric structure, is convenient to machined into, can realize producing in batches, and versatility is extremely strong;
Welding job amount when 3, having reduced assembling changes the place of welding originally into present be threaded, and has improved the harmless replaceability of stuffing box gland;
4, simplified drive link assembly process and positioning tool, need not any frock during assembling, weld bond is one at most, has improved installation efficiency significantly, and mechanism's quality and precision have also obtained the raising of very big degree simultaneously.
