Problems solved by technology

However, in practice, many factors in the continuous dynamic weighing process of electronic belt scales will affect the measurement accuracy of electronic belt scales, such as changes in belt tension, belt deviation, and changes in material types. For the electronic belt scale on the material belt machine, the accuracy of the measurement data of each material cannot be guaranteed
[0004] The measurement of bulk materials on ships at the wharf is also carried out by ships after unloading, and then transferred to truck scales for static measurement. This measurement method can ensure the accuracy of measurement data, but the cost of transshipment is high and all bulk raw materials for steel plants and thermal power plants are used. This method requires a lot of manpower and material resources, and because there are many ships unloaded at the wharf, there are many types of materials, large quantities, and high cost, so it is unrealistic to use all the truck scales for static measurement.

Abstract

The invention discloses an automatic static metering system and an automatic control method for continuous material unloading at a dock. The automatic static metering system comprises a material distributor of a material conveying device, a material weighing device, a metering operation station, a local metering server, a PLC and a basic automatic operation station. The material weighing device is composed of a first weighing hopper, a second weighing hopper, a first weighing sensor set, a second weighing sensor set, a first weighing instrument and a second weighing instrument. The PLC controls the material distributor and a hydraulic drive device of the material weighing device. The PLC, the first weighing instrument and the second weighing instrument are connected with the metering operation station. The metering operation station is used for reading signals of the PLC and data displayed by the first weighing instrument and the second weighing instrument in real time and storing the data in the local metering server. The basic automatic operation station controls the PLC. Information of bulk materials on ships from the moment when the materials enter the dock to the moment when the materials are weighed and unloaded is mastered comprehensively, and the material metering accuracy is improved.

Description

technical field [0001] The invention relates to continuous automatic metering of materials in metallurgy, mines and wharves, in particular to an automatic static metering system for continuous unloading of wharf materials and an automatic control method. Background technique [0002] For a long time, large-scale iron and steel plants, thermal power plants and other enterprises have measured bulk materials such as iron ore, coal, pellets, and limestone transported by ships through ship inspection. After the ship has checked the heavy load, the ship The material is transported to the rear land storage area through the belt conveyor, and the operation process is a continuous unloading process. [0003] The most important issue in the unloading of bulk materials at the wharf is the continuity of unloading, and the effective measurement and statistics of bulk materials can be carried out without affecting the unloading operation rate. With the advancement of science and technolo...
