Conveying type on-line drying device and drying system with same

Abstract

The invention provides a conveying type on-line drying device and a drying system with the same. The drying device comprises a material conveying bin, a paddle type conveying shaft arranged in the material conveying bin, a material inlet formed in the top of one end of the material conveying bin, a material outlet formed in the lower portion of the other end of the material conveying bin, an openable bin cover arranged on the top of the material conveying bin, and a hot air inlet formed at the material inlet. The bin cover extends from the inner side of the material inlet to the tail end of the material conveying bin. The conveying type on-line drying device is simple in structure, easy to manufacture, apply and popularize and capable of drying broken raw coal on line, and does not need to occupy a large area of land, waiting is avoided, the production efficiency is greatly improved, and particularly the production cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of coal preparation, and in particular relates to an online coal drying device. Background technique [0002] In the traditional coal preparation process, in order to reduce the adverse effects of moisture in the selected materials on the coal preparation equipment, system or process, and to improve the efficiency and quality of coal preparation, the raw coal is generally dried before it is sorted. [0003] The specific method is to stack the crushed raw coal under the shed, and mainly rely on air drying to dry naturally. This method is slow to dry, takes up a lot of land, is inefficient, and is unevenly dried, which increases production costs. Contents of the invention [0004] The purpose of the present invention is to provide an on-line coal drying equipment and system to realize rapid drying of raw coal, reduce land occupation, improve production efficiency and reduce production costs. [0005] The te...
