Description

Rotary blockage clearing device

Technical Field

The utility model relates to clear stifled device field, concretely relates to rotatory clear stifled device.

Background

In daily industrial production, the use of storage bins for granular materials such as coal dust, ore powder and the like is very popular, and the function of the storage bins cannot be underestimated. However, the material blockage phenomenon often occurs in the discharging process of the storage bin, and the normal work of the equipment is seriously influenced. In particular, once the coal powder blockage occurs in a large-scale thermal power plant which is provided with a coal powder cabin of a direct-fired pulverizing system and a coal tower of a coking plant, a generating set is forced to reduce power and throw load urgently, even a large amount of oil is put into the boiler due to unstable combustion, and the boiler is put out of fire and the unit is not shut down in plan more seriously. Once the coal feeding blockage occurs in a coking plant, the whole coal blending proportion is disordered, the coal conveying is interrupted in serious cases, and how to clear the blockage of the storage bin becomes an important problem.

In order to realize the purpose, the utility model provides a technical scheme is:

rotatory clear stifled device, including the hopper, hopper upper end and lower extreme are fixed with respectively and are fitted with a contraceptive ring and lower ring, it is equipped with the lantern ring to fit with a contraceptive ring the pot head on the upper ring, first annular has been seted up to the lower ring inner edge, first annular internal rotation is provided with the inner ring, it passes through a plurality of scraper fixed connection to go up lantern ring and inner ring, the scraper is provided with the clearance with the hopper inner edge, it is fixed with outer ring gear to go up lantern ring outer fringe, the hopper outer fringe is fixed with the layer board, the layer board upper end is fixed with the motor, be fixed with the gear with outer ring gear engagement on the output shaft of motor, the second ring groove has all been seted up on the inner ring inner edge of first annular top and below, two upper and lower second ring groove longitudinal symmetry set up, the second ring.

Specifically, the scraper in the hopper is through a plurality of solid fixed ring fixed connection, and a plurality of solid fixed ring set up along the length direction equipartition of scraper, and a plurality of solid fixed ring from the top down's diameter reduces in proper order.

Specifically, a plurality of universal balls are evenly distributed on the circumference of the outer edge of the inner ring and are in rolling contact with the side groove wall of the first annular groove.

Specifically, the plurality of scrapers are uniformly distributed according to the circumference of the axis of the hopper.

Specifically, the baffle ring is in rotational contact with the groove wall of the second annular groove.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses, simple structure, convenient to use, low in manufacturing cost, stable in structure is reliable, convenient maintenance, and it is effectual to clear stifled, thereby can prevent that the powdery material from entering into the rotation that influences the inner ring in the first annular, has improved its life.
