Coal-leveling device and coal-leveling method

Abstract

The invention relates to a coal-leveling device and a coal-leveling method. The coal-leveling device comprises a coal-leveling device trolley, wherein the coal-leveling device trolley consists of a small frame, a walking mechanism, electro-hydraulic single-cylinder dual push rods, a gear motor and a coal-leveling mechanism, wherein the coal-leveling device trolley can move reversely along a trolley walking track; the top of a coal cabin between dual tracks of the trolley walking track is provided with a coal-leveling hole; the gear motor is arranged on the small frame; the lower part of the gear motor is connected with the coal-leveling mechanism through the electro-hydraulic single-cylinder dual push rods; the coal-leveling mechanism extends into the coal cabin through the coal-leveling hole; the coal-leveling mechanism can be driven to move upwards and downwards by the electro-hydraulic single-cylinder dual push rods; the electro-hydraulic single-cylinder dual push rods and the coal-leveling mechanism can rotate around a horizontal direction under the driving action of the gear motor. According to the coal-leveling device and the coal-leveling method, a mechanical coal-leveling way is adopted, so that the effective volume of a large-sized storage coal cabin is increased, single-row material-distributing wires on the cabin top can be adopted instead of dual-row material-distributing wires, and the distribution equipment cost is saved; the floor space of a material-distributing plant and other facilities on the coal cabin top is reduced, and the engineering building cost is saved.

Description

technical field [0001] The invention relates to a coal leveling device on the top of a large-scale Kong coal blending bunker, in particular to a coal leveling device and a coal leveling method for the top of a Φ18m and Φ21m large storage and blending bunker. Background technique [0002] At present, coal storage sites in coking plants are mainly divided into two categories: coal yards and large coal bunkers. Recently, the newly promulgated "Coking Industry Access Conditions" (revised in 2014) requires that the newly built coal yard must be closed, which greatly increases the cost of the new coal yard. Therefore, large coal bunkers will increasingly become the first choice for new coking plants. [0003] In order to increase the effective volume of the coal bunker, the existing large-scale coal storage and blending bunker in China generally adopts the double-row distribution method. However, due to the natural accumulation of materials, the effective volume of the coal bunke...

Problems solved by technology

In addition, the use of double-row material distribution by unloading trucks not only increases the cost of material distribution equipment, but also increases the size of the transfer station before entering the coal bunker, and the corridor must also be double-row, which greatly increases the cost of land occupation and infrastructure; if a reversible mobile belt is used The double-row material distribution of the type conveyor will not only increase the equipment cost, but also need to add a layer of material distribution workshop on the top of the coal bunker; therefore, the double-row material distribution method will increase the area of ​​the material distribution workshop on the top of the coal bunker and increase the construction and installation costs of the project.
