Description
Technical field
The utility model is suitable for high temperature exhaust blower shaft end smoke impervious, belongs to metallurgical off-gas acid-making technical field, specifically
Ground is said, a kind of device for reducing high temperature exhaust blower sealing smoke spillage is related to.
Background technique
During metallurgical off-gas acid-making, flue gas enters high temperature exhaust blower through electric precipitator, since high air draft machine shaft end is close
Positive pressure is larger at envelope, and flue gas is made to leak from sealing place.
Therefore, it is necessary to be improved to existing high temperature exhaust blower shaft sealer, so that high temperature exhaust blower sealing fills
The structure set is more perfect, under the premise of not increasing mass production cost, maximizes and guarantees high temperature exhaust blower shaft sealer
Stability, make it have higher practicability.
Summary of the invention
In order to solve the problems, such as background technique, the utility model provides a kind of reduction high temperature exhaust blower sealing cigarette
The device of gas leakage, to solve poor sealing performance, inconvenient problem with use.
In order to achieve the above objectives, the utility model is implemented by following technical solution:
The device of the reduction high temperature exhaust blower sealing smoke spillage includes fan casing, blower fan main shaft, compresses dress
It sets, sealing device, the sealing device is connect with fan casing by pressing device, and sealing device includes bottom plate, gland, close
Packing material, lower surface of base plate are bonded with casing, and gland is located at plate upper surface, bottom plate and gland and is locked by clamping screw, institute
The bottom plate and gland stated are equipped with the groove to match with airtight and watertight padding size, and airtight and watertight padding is closely connect with blower fan main shaft.
Further, the pressing device is ┐ type block, and pressing device one end is bonded with plate upper surface, the other end and wind
The fitting of machine casing, and locking is connect with fan casing by hold-down bolt.
Further, the sealing device matches with blower fan main shaft size.
Further, the airtight and watertight padding is graphite packing.
Further, the bottom plate and gland are equipped with the bolt hole to match with clamping screw size.
The utility model has the beneficial effects that
The utility model provides a kind of device for reducing high temperature exhaust blower sealing smoke spillage, simple with structure,
The advantages that easy to operate, investment cost is low, safe and practical is installed, it, can be effective suitable for the sealing of high temperature exhaust blower shaft end flue gas
Blower smoke spillage amount is reduced, metallurgical off-gas acid-making industry is widely used in.
