Abstract
The utility model proposes a kind of cement grinding mill tail discharging weight flap valve valve shaft sealing device, it includes cement grinding mill tail discharging weight flap valve valve body and valve shaft, the fixed valve shaft sealing device of difference on valve body both sides, fill out in each valve shaft sealing device and set felt filler, each valve shaft sealing device sets FC rolling bearing units respectively, set weight linkage respectively at valve shaft two ends, valve shaft also sets valve plate.This utility model is by multi-sealed to carrying out between turnover panel valve shaft and valve body, it is ensured that effective sealing of valve shaft and valve body, has stopped cement dust and has outwards run and emit, has eliminated the pollution to site environment.
Description
Technical field
This utility model relates to cement grinding mill tail discharging weight flap valve, is specifically related to a kind of cement grinding mill tail discharging weight flap valve valve shaft sealing device.
Background technology
Cement mill afterbody discharging lock wind devices is monolayer weight flap valve, it is mainly made up of parts such as valve body, valve plate, valve shaft, connecting rod, weights, the method mainly utilizing equalising torque realizes lock wind and unloads ash, i.e. when the moment that the moment that the material acted on turnover panel produces produces more than weight rocking bar, valve plate is opened and is unloaded ash, after once dust stratification sheds, the moment that weight and connecting rod produce makes valve plate close rapidly, it is thus possible to ensure to lock wind in time when not unloading ash.Seal between original valve shaft and valve body and use monolayer felt seal, two ends support and use SN206 rolling bearing units, in actual production process, flap valve is after a period of operation, arise that the situation that felt weares and teares, at this moment will outwards emit ash from the space between valve shaft and valve body, pollute site environment, in order to solve to emit ash problem, need to regularly change felt seal.
Summary of the invention
Technical problem to be solved in the utility model relates to a kind of cement grinding mill tail discharging weight flap valve valve shaft sealing device, and utilizing this device to make between valve shaft and valve body can effectively seal, and solves to emit grey situation because sealing felt abrasion causes.
For solving above-mentioned technical problem, technical solution adopted in the utility model is: a kind of cement grinding mill tail discharging weight flap valve valve shaft sealing device, including cement grinding mill tail discharging weight flap valve valve body and valve shaft, on the basis of valve shaft center, on valve body, fixed valve shaft sealing device is distinguished in described valve body both sides, fill out in each valve shaft sealing device and set felt filler, each valve shaft sealing device sets FC rolling bearing units respectively, sets weight linkage respectively at valve shaft two ends, valve shaft also sets valve plate.
This utility model uses the cement grinding mill tail discharging weight flap valve valve shaft sealing device designed by technique scheme, due to multi-sealed to having carried out between turnover panel valve shaft and valve body, use FC form rolling bearing units simultaneously, there is sealing these bearing both sides, make to form a confined space by steel duct between valve body and bearing block, ensure that effective sealing of valve shaft and valve body, stopped cement dust and outwards run and emit, eliminated the pollution to site environment.
Accompanying drawing explanation
Fig. 1 represents the structural representation of this utility model cement grinding mill tail discharging weight flap valve valve shaft sealing device.
Detailed description of the invention
Below in conjunction with the accompanying drawings the structure of this utility model cement grinding mill tail discharging weight flap valve valve shaft sealing device is illustrated.
See Fig. 1, this utility model cement grinding mill tail discharging weight flap valve valve shaft sealing device, including cement grinding mill tail discharging weight flap valve valve body 1 and the valve shaft 2 being installed on valve body 1, on the basis of valve shaft center, on valve body 1, fixed valve shaft sealing device 6 is distinguished in valve body 1 both sides, valve shaft sealing device 6 is with steel pipe one joint that a length of 80mm internal diameter is 100mm, its one end is welded on valve body 1, other end welding circular flange.Fill out in each valve shaft sealing device 6 and set felt filler 7, felt filler 7 be be cut to internal diameter be 30mm external diameter be the multilamellar felt of 100mm.Each valve shaft sealing device 6 sets FC rolling bearing units 3 by connecting bolt 8 respectively and replaces the SN206 rolling bearing units of existing use, bearing block flange is attached fixing with welded flange of steel tube bolt, set weight linkage 4 respectively at valve shaft 2 two ends, valve shaft 2 also sets valve plate 5.
This utility model is tried out through design improvement, it is possible to realize effective sealing of valve shaft and valve body, has stopped cement dust and has outwards run and emit, has eliminated the pollution to site environment.
