Abstract

The invention discloses conveying equipment for a coal mill outlet. The conveying equipment comprises a front end conveying pipeline, a rear end conveying pipeline and a bend. The front end conveyingpipeline and the rear end conveying pipeline are used for coal conveying. The bend is used for changing the coal conveying direction. One end of the front end conveying pipeline is connected with thecoal mill outlet, and the other end of the front end conveying pipeline is connected with the bend. One end of the bend is connected with the front end conveying pipeline, and the other end of the bend is connected with the rear end conveying pipeline. The conveying equipment is characterized in that each of the front end conveying pipeline, the rear end conveying pipeline and the bend comprises an outer-layer casing pipe and an inner-layer liner plate arranged in the outer-layer casing pipe; a spiral conveying groove is formed in the front end conveying pipeline, a strengthening layer is arranged in the bend and used for screening coal, the strengthening layer divides the bend into a bend upper layer and a bend lower layer, a partition layer is arranged in the rear end conveying pipeline,and the partition layer is connected with the strengthening layer.

Description

technical field [0001] The invention relates to the field of coal conveying equipment, in particular to a conveying equipment used for the outlet of a coal mill. Background technique [0002] Coal is currently one of the main sources of national energy. The utilization efficiency of coal is related to its size. The smaller the size, the more fully the coal will be burned. Therefore, coal pulverizers are mostly used in coal processing. The coal pulverizer is a machine that breaks the coal block and grinds it into coal powder. After the coal is ground into coal pulverized by the coal pulverizer, it is transported through the conveying equipment at the outlet of the coal mill. The conveying equipment can realize horizontal conveying, inclined conveying, etc., conveying The equipment is being conveyed. In order to change the conveying direction, elbows are generally used to change the conveying direction. The existing conveying equipment at the outlet of the coal mill has coal ...
