Abstract
The utility model discloses a rotary joint of a roller slag cooler. The rotary joint comprises a mandrel, a sealing head, a safety valve, a pressure switch, a water inlet shell, a packing seal which is arranged between the mandrel and the water inlet shell, a gland which is adjacent to the packing seal and arranged on the mandrel, a thrust bearing which is adjacent to the gland and arranged on the mandrel, a fastening nut, a water outlet shell, a carbon fiber and muddy packing combined seal which is arranged between the mandrel and the water outlet shell, a bearing seat, a bearing, a bearing cover, a felt ring oil seal which is arranged between the mandrel and the bearing cover, a thermometer which is arranged on one side of the water outlet shell, and a flow switch which is arranged on the other side of the water outlet shell. The rotary joint of the roller slag cooler is compact in structure, steady in operation, low in noise, low in abrasion, safe, reliable, energy-saving, consumption-reducing, high in sealing performance, easy to repair and convenient to monitor, can be widely applied to a circulating fluidized bed boiler slag-cooling system and can be widely applied to other rotary heat exchange equipment.
Description
Technical field the present invention relates to a kind of barrel slag cooler swivel joint, can be widely used in also can be applicable in other the rotating heat transfer equipment in the cold slag system of circulating fluidized bed boiler.
Background technology is along with China's boiler technology makes constant progress, the continuous increase of boiler unit, and the subsidiary engine supporting with it also had huge development.Barrel slag cooler is the nucleus equipment of recirculating fluidized bed bottom slag treatment system, and swivel joint is again the critical component of barrel slag cooler, its performance determine cold slag machine whether can be efficiently, stable, safe operation.The relatively rotating parts of swivel joint is inner mandrel with the cold slag machine drum body rotation and the housing of external stability, and interior inner rotary adopts packing seal, and sealing was lost efficacy easily, easily leaked.There are serious problems in the radial support of swivel joint housing, and the small dimension housing relies on seal to support on the mandrel, and seal is subjected to the compressing of housing deadweight in rotatablely moving, lax below the top pressurized, unbalance stress, seal itself and axle be serious wear all, poor sealing performance easily leaks; Large specification housing adopts independent fixed support, and mandrel is followed together circular runout of cylindrical shell.Therefore, between mandrel and the housing, housing and its occur interfering between fixing, interference can cause seal failure, even causes inner shaft loosening or damage to clamp nut, thereby produces dangerous.Domestic once the appearance because of the swivel joint internal intervention causes nut to lose efficacy, and swivel joint housing fly bomb under water under high pressure promotes penetrates, and causes the dead event of maintainer.The axial restraint of housing adopts fastening nuts, relatively rotates between housing and the mandrel simultaneously, is sliding friction between stainless steel iron plate, and resistance is large, and is large to the clamp nut active force, and nut is loosening, damage easily, can cause serious production accident.Therefore the performance of swivel joint not only is related to the normal operation of equipment, is related to especially personal safety.
Summary of the invention the object of the present invention is to provide a kind of compact conformation, operates steadily, noise is little, wear extent is little, safe and reliable, energy-saving and cost-reducing, good seal performance, maintenance easily, monitor easily barrel slag cooler swivel joint.
In order to achieve the above object, barrel slag cooler swivel joint of the present invention, comprise mandrel, be installed in the end socket in mandrel left side, be installed in the safety valve on the end socket side, be installed in the pressure switch on the seal head end side, be installed on the mandrel, and be fixed on water inlet housing on the end socket, be installed in the packing seal between mandrel and the water inlet housing, be installed in gland on the mandrel near packing seal, be installed in thrust bearing on the mandrel near gland, be installed in clamp nut on the mandrel near thrust bearing, be installed on the mandrel and be fastened to into the water outlet housing of water housing right-hand member, be installed in carbon fiber and muddy packing combination sealing between mandrel and the water outlet housing, be installed in bearing block on the mandrel near combination sealing, be installed in the bearing between mandrel and the bearing block, be fastened to the bearing cap on the pedestal cap, be installed in the felt collar oil sealing between mandrel and the bearing cap, be installed in the thermometer on water outlet housing one side, be installed in the flow switch on the water outlet housing opposite side.
Barrel slag cooler swivel joint of the present invention, its operation principle is: water at low temperature enters swivel joint by water inlet, enters the inner core of mandrel by housing, enter again the heat transfer zone of cold slag machine, high-temperature water after the heating returns the urceolus of mandrel, enters the swivel joint housing again, discharges from delivery port.In let out between the mandrel inner core in district and the stationary housing and adopt packing seal, adopt carbon fiber and muddy packing combination sealing between the swivel joint mandrel urceolus in the district of leaking and the stationary housing.Housing axially and radially all rely on corrosion resisting bearing to fix.
Barrel slag cooler swivel joint of the present invention, in let out between the inner core of mandrel in district and the water inlet housing and adopt packing seal to seal by gland, because the seal external and internal pressure is identical, the bearings gap is even, therefore, light abrasion, sealing is simple.Leak and adopt carbon fiber and muddy packing combination sealing between urceolus and the water outlet housing of mandrel in district, because there being pressure differential inside and outside the seal, this rotatory sealing is complicated, adopts bearings can guarantee that the gap is even, adds conveniently after the muddy packing attrition.Whole standing part radially adopts stainless steel roller bearings and location; Axially rely on the stainless steel thrust bearing to fix.
Barrel slag cooler swivel joint of the present invention, housing adopt toggle that moment of torsion is provided, and utilize bearing to navigate on the mandrel.Whole swivel joint can be followed the cold slag machine drum body radial floating, without inside and outside interference problem.
Barrel slag cooler swivel joint of the present invention, compact conformation, whole shell axially fasten the employing double nut, fastening direction and barrel body rotation opposite direction can not become flexible during work, and be safe and reliable.Because adopting the bearings location, frictional force is little during rotation, and the Water Pressure power that nut only bears is without inside and outside interfering edge.The housing radial support adopts corrosion resisting bearing to support on the mandrel, and housing and mandrel gap are fixed when work, operate steadily, and noise is little, and wear extent is little, and is safe and reliable, energy-saving and cost-reducing.
Barrel slag cooler swivel joint of the present invention adopts the corrosion resisting bearing location between the stationary housing of barrel slag cooler swivel joint and the rotation mandrel, adopt carbon fiber filler and high-quality muddy packing combination sealing, and good seal performance can be added after the attrition online.
Barrel slag cooler swivel joint of the present invention adopts between all housing parts to be threaded, and maintenance easily.Swivel joint is provided with safety valve, water-thermometer, pressure switch, flow switch, and monitoring is convenient.
In sum, barrel slag cooler swivel joint of the present invention, compact conformation operates steadily, and noise is little, and wear extent is little, and is safe and reliable, energy-saving and cost-reducing, good seal performance, maintenance is monitored conveniently easily.
