Problems solved by technology

[0004] Silo coal storage has been adopted in power plants and coal mines, but coal mines and power plants have short coal storage time, small storage capacity, single process flow, low efficiency requirements, single coal variety and do not involve the mixing of different coal types. The most important thing about coal storage in ports is high efficiency, multi-variety, mixed coal, high throughput and long storage time. Appropriate transformation and improvement of coal storage silo in terms of structure, function and use method

Embodiment Construction

[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0019] The bottom of the large coal storage silo in the port is equipped with multiple outlets, and a feeder 2 for unloading can be installed at each outlet. The setting of multiple feeders 2 can increase the maximum unloading capacity . The number of feeders 2 and the arrangement of feeders 2 at the bottom of the silo can be set according to factors such as the size and shape of the silo bottom, the size of the feeder 2, the demand for unloading capacity, and the limitation of unloading speed. At least one belt conveyor 3 can be arranged below a plurality of feeders 2, and the coal stored in the silo can be unloaded from the discharge port through the action o...

Abstract

The invention provides a discharge control method and a system for a silo. The discharge control method includes the following steps of S1, measuring a material flow on a belt conveyor (3) which is started; S2, comparing the measured material flow with a belt conveyor preset value, and S3, adjusting a material discharge quantity of at least one feeder (2) which the belt conveyor (3) corresponds to according to a comparison result. By means of the discharge control method and the system for the silo, the flow of materials to be conveyed can be set as the belt conveyor preset value according to a production scheduling plan of a coal transporting port, the actual material flow of the belt conveyor (3) can accord with the belt conveyor preset value through the adjustment of the material discharge quantity of the feeder (2) located at the bottom of the silo, and thereby the material flow can be controlled.

Description

technical field [0001] The invention relates to material discharge control, in particular to a material discharge control method and a material discharge control system for a large coal storage silo in a port. Background technique [0002] The port is the hub of the main artery of transportation. In order to realize the safe and effective cargo pivot function in the port, professional and automated storage, transportation and loading processes are essential. According to the characteristics of materials, the scale of freight, and the efficiency of material storage and transportation, various material storage scheduling schemes are used in today's port transportation to coordinate freight. For example, grain, cement and other materials are mostly stored in silos, while coal ore is mostly stored in open yards. [0003] For coal transport ports, storage in open storage yards will cause great pollution to the environment and the materials stacked are easily affected by the weat...
