Abstract
An underwater bearing protection device of blast furnace slag washing system. The device mainly technical problems such as short operational life and inconvenient repair of current bearing in water slag tank of blast furnace slag washing system. Essentials of technical plan of the utility model are: A water tank is installed in the water tank, upper port of the water tank is higher than water level in the water slag tank, a shaft hole for installing a shaft is arranged on one end at lower part of the water tank, the shaft and the shaft hole form sealing fit, lower part of the shaft runs through the shaft hole and makes fit connection with the bearing in the water tank. A seal ring can be also installed between the shaft and the shaft hole, the seal ring makes sealing fit with the shaft hole and the shaft. The utility model can make water sealing for the water tank and the water slag tank, and separates water between the water tank and the water slag tank, the workers can go down to check the bearing at any time, slag washing stop is unnecessary, pumping out water from the tank completely is also unnecessary, so the utility model improves operational environment of the bearing greatly, is favorable for increasing operational life of the bearing, has outstanding economic benefit, and can be widely used for operation in adverse environments such as blast furnace slag washing system.
Description
Technical field
The utility model relates to a kind of bearing protecting device, especially a kind of safety guard that can be used for blast furnace slag flushing system water lower bearing.
Background technology
The existing bearing sealing is just installed rubber seal at the axis hole place of bearing cover and is contacted with bearing, adopt the bearing of this kind method sealing in the dense environment of slag sand, to use, the sealing-ring because slag sand weares and teares gradually, and can enter in the bearing, bearing is worn and torn, thus the work-ing life of having reduced bearing significantly.Bearing will be in the bottom operation near the granulating pit of 90 ℃ of water temperatures under water especially for the big screw feeder of blast furnace slag flushing system, mean lifetime has only two months, also be not easy to check and light maintenance, as carry out routine inspection in every month, must drain Chi Shui, all to stop flushing cinder six hours, not only cause production passive, and have a strong impact on economic benefit.
Summary of the invention
The purpose of this utility model provides a kind of long service life, the blast furnace slag flushing system water lower bearing safety guard of easy access again.
The technical scheme that its technical problem that solves the utility model adopts is: tank 5 is installed in granulating pit 1, and the upper notch that makes tank 5 is higher than the water surface in the granulating pit 1, tank 5 bottoms one side is provided with the axis hole that is used for installation shaft 2, axle 2 becomes to be sealed and matched with axis hole, and spools 2 bottom is passed axis hole and cooperated connection at tank 5 with bearing 4.Also can cooperate sealing-ring 3 is installed between axle 2 and axis hole, sealing-ring 3 is sealed and matched for 2 one-tenth with axle with axis hole respectively.
The beneficial effects of the utility model are: short in order to solve existing bearing operation life in the granulating pit of blast furnace slag flushing system, be not easy to maintenance again, and have a strong impact on problems such as economic benefit, the utility model is installed in the granulating pit by manufacturing and designing a tank, and making notch be higher than the water surface, bearing is installed in the groove.Because tank becomes water-lute that water is between the two isolated mutually with granulating pit, so the workman can go down at any time bearing is checked, needn't stop flushing cinder, must not drain Chi Shui yet.Therefore improve bearing running environment greatly, helped improving the work-ing life of bearing, remarkable in economical benefits.It can be widely used in moving in the severe environment such as various blast furnace slag flushing system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-granulating pit, 2-axle, 3-sealing-ring, 4-bearing, 5-tank.
Embodiment
That the utility model is described in further detail is as follows below in conjunction with embodiment:
Embodiment 1, the utility model is by being equipped with tank 5 in granulating pit 1, and the upper notch that makes tank 5 is higher than the water surface in the granulating pit 1, tank 5 bottoms one side is provided with the axis hole that is used for installation shaft 2, axle 2 becomes to be sealed and matched with axis hole, also can make the top of axle 2 stretch out granulating pit 1 open topped, the bottom of axle 2 is passed axis hole and is cooperated connection at tank 5 with bearing 4, it is short to solve existing bearing operation life in the granulating pit of blast furnace slag flushing system preferably, be not easy to maintenance again, and have a strong impact on problems such as economic benefit, because tank becomes water-lute that water is between the two isolated mutually with granulating pit, so the workman can go down at any time bearing is checked, needn't be stopped flushing cinder, also must not drain Chi Shui; Therefore improve bearing running environment greatly, helped improving the work-ing life of bearing.It can be widely used in moving in the various severe environment such as blast furnace slag flushing system.Consult Fig. 1 to Fig. 3.
