Bucket wheel reclaimer applied to bulk cargo blending operation

Abstract

The invention discloses a bucket wheel reclaimer applied to bulk cargo blending operation. The bucket wheel reclaimer comprises a bucket wheel, a cantilever belt conveyer, a steel structure, a first head funnel, a buffer bucket, an electric gate, a vibrating feeder, a weighting feeder, a second head funnel and a material guiding chute; the bucket wheel is arranged at one end of a cantilever crane,the other end of the cantilever crane stretches into the first head funnel, and the cantilever belt conveyer is arranged on the upper surface of the cantilever crane; the bottom of the first head funnel is connected with the top of the buffer bucket, the vibrating feeder is arranged under the bottom of the buffer bucket, and the electric gate is arranged on the side wall of the bottom of the buffer bucket; and the weighting feeder is arranged at an outlet of the vibrating feeder, the second head funnel is arranged at an outlet of the weighting feeder, and the material guiding chute is arranged under the second head funnel and located over a storage yard belt conveyer. According to the bucket wheel reclaimer applied to bulk cargo blending operation, the purpose that different varieties ofbulk cargoes are precisely fed according to the proportioning requirements is achieved, it is guaranteed that the flow is accurate and controllable, the bulk cargoes are gathered to the storage yard belt conveyer located on the same way, and high-precision blending is achieved.

Description

technical field [0001] The invention relates to the technical field of port bulk cargo mixing operations, in particular to a bucket wheel reclaimer applied to bulk cargo mixing operations. Background technique [0002] Under the strong impetus of industrial development, in order to meet the needs of coal for power plant fuel and iron ore for steel mill raw materials, in recent years, many large coal reserve base terminals and iron ore transfer terminals have been built along the coast of my country to meet the needs of coal and iron ore. Unloading, loading, stockpiling and other operation requirements of stone in the port. [0003] my country's coal reserves are very rich, mainly concentrated in Shanxi, Shanxi, and western Inner Mongolia. The coal characteristics of each region, including key indicators such as moisture content, ash content, sulfur content, and calorific value, vary greatly, and coal purchase prices also vary greatly. Coal is an important fuel cost for power...

Problems solved by technology

[0006] For method 1, the mixing function is simple and the overall cost is low. However, during the reclaiming process of the bucket wheel reclaimer, the reclaimed weight of each bucket fluctuates greatly, reaching about 5-10%, which makes the mixing of different types of bulk goods difficult. The matching accuracy is low, only rough matching can be achieved, and it is difficult to meet the quality control requirements of power plants and steel mills after mixing

[0007] For the second method, because the material is discharged through the silo, the discharge flow is controllable, and the mixing accuracy is high, which can reach about 0.5~1%, which meets the quality control requirements of power plants and steel mills after mixing. However, due to the silo Independent construction is required, and supporting facilities such as electric control, water supply and drainage, fire protection, and dust removal are required, which makes the overall cost high and also affects the promotion and use of this method in the industry
