Wholly-weighed storage bin based on plurality of discharging scrapers

Abstract

The invention discloses a wholly-weighed storage bin based on a plurality of discharging scrapers. The wholly-weighed storage bin based on a plurality of discharging scrapers comprises cylindrical storage bins; the outer sides of the storage bins are additionally provided with a plurality of layers of reinforcing ribs fixedly connected with corbel supports; and the corbel supports are fixedly connected to a girder among the storage bins so as to achieve the aim of stabilizing the storage bins. The corbel supports are provided with measuring sensors which are arranged at different heights of the storage bins and are used for measuring each layer so that the average value of all layers measured by the measuring sensors is obtained. The wholly-weighed storage bin based on a plurality of discharging scrapers also comprises the plurality of discharging scrapers, driving devices and a transmission device, and the rotating speeds of the discharging scrapers are regulated by the driving devices and the transmission device according to different discharging requirements so that different discharging rotating speeds are achieved. The wholly-weighed storage bin based on a plurality of discharging scrapers has the beneficial effects that the storage bins can be wholly weighed, precise coal conveyance can be realized, and the relatively high coal conveying requirement can be met.

Description

technical field [0001] The invention relates to the field of thermal power generation, in particular to an integral weighing storage bin based on multiple unloading scrapers. Background technique [0002] At present, the raw coal bunker used in power plants is an important storage link in the pulverization system of thermal power plants. The continuity of its operation is directly related to the combustion conditions of the furnace and affects the safe operation of the unit. In current thermal power plants, in order to increase the fluidity of materials, the bottom of the raw coal bunker is mostly in the shape of an inverted cone or a hyperbolic cone. In addition, limited by the entrance of the weighing belt feeder, the size of the exit of the raw coal bunker is small, and the coal will creep downwards by its own weight, and the exit is easy to block, especially in rainy days and low temperatures, coal blockage will occur more serious. Therefore, for traditional raw coal b...

However, using these two methods is not only inefficient, but also has dead spots to clean up, so the longer the time, the less obvious the effect will be

The discharge scraper method is used to prevent blockage. After the material falls, it is easy to accumulate under the discharge scraper. When encountering large or hard materials, the discharge scraper is prone to warping after a long period of operation. When the unloading scraper is upturned, the anti-blocking effect will be greatly reduced, and it is easy to cause damage to related equipment, resulting in increased production costs
