Abstract
This application discloses a kind of high-temperature blower shaft sealers, belong to high-temperature centrifugal fan field, the sealing for blower fan main shaft and fan casing comprising the sealed base being welded on fan casing is equipped with connecting plate by bolt assembly on sealed base；Seal casinghousing is equipped with by bolt assembly on the connecting plate, is equipped with asbestos pad between seal casinghousing and connecting plate, between connecting plate and sealed base；The other end of seal casinghousing is connect with seal receptacle.In view of above-mentioned technical proposal, the application can be realized the sealing between fan casing and transmission shaft, solve the problems, such as that gas leaks.
Description
Technical field
The application belongs to high-temperature centrifugal fan field, specifically, more particularly to a kind of high-temperature blower shaft sealer.
Background technique
High-temperature centrifugal fan is widely used in chemical industry, petroleum, metallurgy, forging usually as a kind of machinery for conveying gas
The field of industrial production such as pressure, electric power can usually generate certain high temperature in these field of industrial production, with mordant gas
Body, in the case where general physical seal, high pressure corrosive gas still is able to let out from the gap between casing and transmission shaft
Leakage causes serious pollution to the working environment at scene, impacts to the physical and mental health of operator.
Summary of the invention
The application's is designed to provide a kind of high-temperature blower shaft sealer, provides a kind of combination sealing mode,
It can be realized the sealing between fan casing and transmission shaft, solve the problems, such as that gas leaks.
In order to achieve the above objectives, the application is achieved through the following technical solutions:
High-temperature blower shaft sealer described herein is installed at the blower fan main shaft between fan casing and body
There is sealed chamber, pressure-air snorkel is connected in sealed chamber.
Further speaking, sealed chamber described herein includes the sealed base being welded on fan casing, close
Connecting plate is equipped with by bolt assembly on back cover seat；Seal casinghousing is equipped with by bolt assembly on the connecting plate, is sealed
Asbestos pad is equipped between shell and connecting plate, between connecting plate and sealed base；The other end and seal receptacle of seal casinghousing connect
It connects.
Further speaking, the link position of seal casinghousing described herein, connecting plate, sealed base and blower fan main shaft
It is mounted on the sealing ring that asbestos cord is material.
Compared with prior art, the beneficial effect of the application is:
The application can be realized the sealing between fan casing and blower fan main shaft, prevent the pernicious gas of high temperature and pressure from upper
It states and is leaked in gap between the two, provide a kind of comfortable safe working environment for field personnel.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the application.
In figure: 1, fan casing；2, sealed base；3, asbestos board；4, pressure-air snorkel；5, asbestos cord；6, it seals
Seat；7, body；8, blower fan main shaft；9, connecting plate；10, seal casinghousing.
Specific embodiment
Technical solution described herein is described further with reference to the accompanying drawings and embodiments.
Embodiment 1: a kind of high-temperature blower shaft sealer, including the blower fan main shaft 8 between fan casing 1 and body 7
Place is equipped with sealed chamber, and pressure-air snorkel 4 is connected in sealed chamber.The sealed chamber includes being welded on fan casing
Sealed base 2 on 1, is equipped with connecting plate 9 by bolt assembly on sealed base 2；Pass through bolt group on the connecting plate 9
Part is equipped with seal casinghousing 10, is equipped with asbestos pad between seal casinghousing 10 and connecting plate 9, between connecting plate 9 and sealed base 2
3；The other end of seal casinghousing 10 is connect with seal receptacle 6.The seal casinghousing 10, connecting plate 9, sealed base 2 and blower fan main shaft 8
Link position be mounted on asbestos cord 5 be material sealing ring.
As shown in Figure 1, the designing points of the application are to carrying out high pressure sealing between fan casing 1 and blower fan main shaft 8
The sealing of chamber solves the gas leakage problem between fan casing 1 and blower fan main shaft 8, suitable work is provided for Workplace
Environment.
Specifically, in this application, the blower fan main shaft 8 stretches out body 7, and is equipped in one end of main shaft 8
Fan casing 1.It is welded with sealed base 2 on the fan casing 1, connecting plate 9 is equipped with by bolt on sealed base 2,
The contact position of connecting plate 9 and blower fan main shaft 8 is equipped with the sealing ring with asbestos cord 5 for material.The connecting plate 9 and sealing
Asbestos board 3 is installed, asbestos board 3 itself has characteristic resistant to high temperature, but also can be to connecting plate 9 and sealing between pedestal 2
The connecting portion of pedestal 2 plays sealing function.
The both ends of seal casinghousing 10 described herein are connect with connecting plate 9, seal receptacle 6 respectively, and seal casinghousing
10 it is same as at the link position of connecting plate 9 asbestos board 3 is installed, to play the effect of high temperature resistant and sealing.The sealing
Pressure-air snorkel 4 is through at the top of shell 10, there are cavitys for the inside of seal casinghousing 10, and in seal casinghousing 10 and wind
The contact position of owner's axis 8 is equally equipped with the sealing ring with asbestos cord 5 for material.
The high pressure gas can form the positive differential pressure relative to fan casing 1 in the inside of seal casinghousing 10, avoid
Because the pressure in fan casing 1 is higher than the pressure outside fan casing 1 so as to cause the leakage of high temperature corrosive gas.
