Abstract
The utility model relates to a rotating shaft sealing component of a sonic ash collector of a boiler, which belongs to the field of machinery. A rotating shaft is sheathed with a movable carbon seal ring which is sealed with the shaft with zero clearance, both sides of the ring are sheathed with static carbon seal rings which are sealed with the shaft with free clearance, a carbon graphite packing and a gran packing gland bush are orderly sheathed outside the static carbon seal ring at one side, the carbon graphite packing is sealed with the shaft with zero clearance, and the free clearance gran packing gland bush is The rotating shaft is penetrated through the outer shell, the carbon seal ring, the static carbon seal rings, the carbon graphite packing and the gran packing gland bush are all packed in the outer shell, and the outer shell is fixed on a sleeve of the rotating shaft. The gran packing gland bush is connected with the outer shell. Bolts on the gran packing gland bush can be twisted to adjust the sealing pressing force of the carbon graphite packing, the static carbon seal rings and the movable carbon seal ring. The utility model can satisfy the operating requirements of long-term no leakage and free maintenance for a steam type sonic ash-removing rotating shaft under the conditions of high pressure, high temperature and high rotating speed.
Description
1, technical field: boiler sound wave ash cleaner rotatingshaft black box of the present utility model belongs to mechanical field.
2, background technique: the boiler sound wave ash cleaner requires the rotatingshaft sealability must satisfy vapor pressure 2.5Mpa, 450 ℃ of temperature, rotating speed 1450r/min, the non-maintaining service condition of long-term nothing leakage.Xu Hao work " sealing " and German glycolylurea thatch K. Miller work works such as " fluid seals technology-principle and application " all do not have the record of the relevant high rotating speed sealing technique of little space bearing high-temperature.Since the necessary anti-450 ℃ high temperature of sealing material, and certain compression resistance is arranged, therefore can not use products such as polyurethane, polytetrafluoroethylene, rubber.Adopt asbestos packing, working life is very short, must often change, and has strengthened the workload of operation maintenance.Use High Temperature High Pressure graphite asbestos packing, do not rise appreciably working time, and it is still very big to change workload.High pressure-temperature graphite asbestos packing wiry is with in use, and increase working time to some extent, but can not satisfy non-maintaining requirement.Use the support aggregate of metal copper sheet as high pressure-temperature wire graphite asbestos packing, divide ply, though prolonged working life, after operation a period of time, the graphite asbestos packing is all washed away damage, and has increased the replacing difficulty.
3, summary of the invention: the purpose of this utility model is to propose a kind of long-term boiler sound wave ash cleaner rotatingshaft black box that leaks non-maintaining service condition that do not have of realizing.
The purpose of this utility model is achieved in that and is with a moving carbon seal ring on steam type sound wave ashing machine rotatingshaft, for the zero clearance seals, rotates with axle between itself and the rotatingshaft.Being with quiet carbon seal ring in these circle both sides, is free clearance between itself and the rotatingshaft, does not rotate with axle.Order is with carbon graphite packing and Glan packing gland outside the quiet carbon seal ring of a side, for the zero clearance sealing, rotates with axle between carbon graphite packing and the rotatingshaft.Be free clearance between Glan packing gland and the rotatingshaft, do not rotate with axle.Rotatingshaft passes shell, and moving carbon seal ring, quiet carbon seal ring, carbon graphite packing, Glan packing gland all are enclosed in the shell, and shell is fixed on the rotary axle box.The Glan packing gland is connected with shell.Turn the bolt on the Glan packing gland, just can adjust its sealing impacting force carbon graphite packing, quiet carbon seal ring, moving carbon seal ring.
Owing to adopt the technological scheme of graphite plane slipper seal, just can satisfy under the high speed conditions of high pressure-temperature, steam type sound wave ashing rotatingshaft does not have the non-maintaining service condition of leakage for a long time.
4, description of drawings: concrete structure of the present utility model is provided by following drawings and Examples
Fig. 1 is a boiler sound wave ash cleaner rotatingshaft seal component architecture schematic representation
5, embodiment:
Legend: 1, rotatingshaft 2, Glan packing gland 3, shell 4, carbon graphite packing 5, quiet carbon seal ring 6, moving carbon seal ring 7, bolt 8, rotary axle box
Embodiment: as shown in Figure 1, on steam type sound wave ashing machine rotatingshaft 1, be with a moving carbon seal ring 6, its with rotatingshaft 1 between for the zero clearance seals, rotate with axle.Being with quiet carbon seal ring 5 in these circle both sides, is free clearance between itself and the rotatingshaft 1, does not rotate with axle.Order is with carbon graphite packing 4 and Glan packing gland 2 outside the quiet carbon seal ring 5 of a side, for the zero clearance sealing, rotates with axle between carbon graphite packing 4 and the rotatingshaft 1.Be free clearance between Glan packing gland 2 and the rotatingshaft 1, do not rotate with axle.Rotatingshaft 1 passes shell 3, and moving carbon seal ring 6, quiet carbon seal ring 5, carbon graphite packing 4, Glan packing gland 2 all are enclosed in the shell 3, and shell 3 is fixed on the rotary axle box 8.Glan packing gland 2 is connected with shell 3.
Turn the bolt 7 on the Glan packing gland 2, just can adjust sealing impacting force carbon graphite packing 4, quiet carbon seal ring 5, moving carbon seal ring 6.
The utility model is applicable to the sealing of the rotatingshaft 1 under the high pressure-temperature condition of little space, and sealing materials such as its alternative original polyurethane, teflon, rubber substitute Sealings such as high and low pressure graphite asbestos packing.
