Problems solved by technology
For the measurement of the amount of coal delivered, the current technology uses a weighing belt machine to measure the amount of coal conveyed by the flow, which belongs to dynamic measurement, and its accuracy is low, generally with an accuracy of 0.5%, which cannot achieve accurate quantitative coal delivery.
[0003] At the same time, due to the inlet restriction of the weighing belt coal feeder, the outlet size of the raw coal bunker is small, and the coal will creep downward by its own weight, so the outlet is easy to block; especially in rainy days and low temperature conditions, the coal blockage phenomenon is more serious

The invention discloses an overall weighing type raw coal bunker which comprises a raw coal bunker, reinforcing ribs, brackets, weighing sensors, a central feeding machine, a cone, a discharge arm, a chassis, a transmission device, a driving device and a discharge hole, wherein the raw coal bunker is a cylindrical raw coal bunker; the reinforcing ribs are mounted on the outer side of the raw coal bunker and fixed on the brackets; the weighing sensors are fixed on the brackets and are uniformly distributed on the raw coal bunker; the corn is arranged at the bottom inside the raw coal bunker; the chassis is arranged at the outlet in the bottom of the raw coal bunker; a fixed gap is formed between the corn and the chassis; the discharge arm is connected with the chassis and is mounted on the transmission device in an overall embedded manner; the driving device is arranged at the lower part of the transmission device and is connected with the transmission device; the discharge hole is formed in the bottom end of the central feeding machine. The overall weighing type raw coal bunker has the beneficial effects that a coal blocking phenomenon is greatly reduced, overall static weighing of the amount of the raw coal bunker is achieved, and the coal conveying precision can be improved.
Description
technical field [0001] The invention relates to the technical field of raw coal bunkers, in particular to a raw coal bunker based on overall weighing. Background technique [0002] At present, the practical raw coal bunker in the power plant is an important storage link in the pulverization system of the thermal power plant. The continuity of its operation is directly related to the combustion conditions of the furnace, which affects the safe operation of the unit. In order to increase the fluidity of materials, the raw coal bunkers in current thermal power plants are mostly in the form of inverted cones or hyperbolic conical bins below the raw coal bunkers. For the measurement of the amount of coal delivered, the current technology uses a weighing belt conveyor to measure the amount of coal transported by flow, which belongs to dynamic measurement, and its accuracy is low, generally 0.5%, which cannot achieve accurate quantitative coal delivery. [0003] At the same time, ...
