Abstract
The utility model discloses a feeding device with blockage prevention and air locking functions of a petroleum coke vertical mill, which comprises a feed hopper and a discharge tube and is characterized in that an impeller shell is connected between the feed hopper and the discharge tube; a rotating shaft is arranged in the impeller shell; and the rotating shaft is connected with windshield stirring blades. The feeding device has compact structure and small volume and can adapt to the limited installation conditions when the petroleum coke vertical mill is positioned at a limited place. The feeding device has the air locking function so as to maintain the constant working condition of a negative pressure of between 5KPa and 6KPa and the constant air separation airflow in the mill, provide the stable working condition for the mill, ensure the quality requirement on the granularity of 200 meshes of ground petroleum coke powder and provide the high-quality petroleum coke powder for spray burning of a kiln.
Description
Technical field
The utility model belongs to petroleum coke vertical mill pay-off, is specifically related to the charging gear of the burnt vertical mill of a kind of float glass process PetroChina Company Limited..
Background technology
In the float glass process, what use always in the vertical mill feeding system of petroleum coke is the belt conveyor feed, and its shortcoming is: belt conveyor takes up an area of big, seals bad and easy blocked portion in the feed process, can not satisfy the required operating mode of grinding machine operate as normal, institute's grinding stone oil coke quality can not guarantee.
Summary of the invention
The purpose of this utility model is to provide a kind of petroleum coke vertical mill charging gear that deters kayser wind that has, to address the above problem.
The technical solution of the utility model is: have the petroleum coke vertical mill charging gear that deters kayser wind, it comprises feed hopper, and discharge nozzle is characterized in that connecting impeller housing between feed hopper and the discharge nozzle, establish rotating shaft in the impeller housing, connect the material toggling blade that keeps out the wind in the rotating shaft.
The described material toggling blade that keeps out the wind is symmetricly set on the impeller sleeve, and impeller sleeve is connected with rotating shaft; The end of the material toggling of keeping out the wind blade is provided with scraper plate.
Institute is set forth in and is hingedly connected with feed hopper charging aperture adjustable plate in the feed hopper.
The contact position of described impeller housing and feed hopper is provided with the guide stiffener.
Described rotating shaft is connected with drive unit.
The utility model compact conformation, volume is little, has in limited time at place, petroleum coke vertical mill place, can adapt to limited mounting condition.Charging gear has lock wind function, keeps 5KPa～6KPa negative pressure operating mode and selection by winnowing air-flow in the constant grinding machine, for grinding machine provides steady working condition, guarantees the quality requirement of institute's grinding stone oil coke powder 200 order granularities, for the kiln torch firing provides high-quality petroleum coke powder.
Description of drawings
Fig. 1 has the petroleum coke vertical mill charging gear structural representation that deters kayser wind.
