High-temperature plate conveying channel, conveyor and sinter cooling system

Abstract

The invention relates to a high-temperature plate conveying channel (L5) which comprises a channel body (1), side thermal insulating material layers (2), side cover plates (3), a bottom thermal insulating material layer (4) and a bottom cover plate (5), wherein the channel body (1) is of a U-shaped or concave structure, and is provided with a bottom surface and two side surfaces; the side thermalinsulating material layers (2) are arranged on the inner surfaces of the side surfaces of the channel body (1); the side cover plates (3) are arranged on the surfaces of the side thermal insulating material layers (2); the bottom thermal insulating material layer (4) is arranged on the surface of the bottom surface of the channel body (1); the bottom cover plate (5) is arranged on the surface of the bottom thermal insulating material layer (4); and the bottom ends of the side cover plates (3) are connected with the bottom cover plate (5). Heat losses of high-temperature materials at the bottomand on the two sides in the conveying process are reduced, material leakage of a conveyor is reduced, and deformation of the conveying channel in the conveying process is reduced, so that the life cycle of the conveying channel is prolonged, and the service life of the conveyor is also prolonged.

Description

technical field [0001] The invention relates to a metallurgical sinter transport system and a cooling system, in particular to a high-temperature plate-type conveying trough, a conveyor and a sinter cooling system, belonging to the field of metallurgical sinter devices. Background technique [0002] The slat conveyor is a conveying device that uses a closed, cyclically running chain as the traction member, and uses butt or lapped parallel plates, corrugated plates, and trough or box-shaped components as the load-bearing components. Apron conveyors are suitable for conveying both bulk materials and finished items. It has been widely used in metallurgy, coal, chemical industry, electric power, machinery manufacturing and other industrial sectors of the national economy. [0003] In the traditional sintering process, there are two parts of waste heat resources: sensible heat of sintering ore (exhaust gas of ring cooler) and sensible heat of flue gas of sintering machine.

Problems solved by technology

[0006] Aiming at the problems existing in the prior art, the present invention provides a high-temperature plate conveying trough, a conveyor and a sinter cooling system, which can reduce the heat loss at the bottom and both sides during the transportation of high-temperature materials, and combine them in the upper part of the conveying trough The heat preservation cover is set to keep the heat of the high-temperature sinter as much as possible until it enters the vertical cooler, and the heat can be more effectively recovered for power generation; at the same time, it solves the uncontrolled opening angle between the conveying chains of the traditional slat conveyor and the process of transporting materials. The problem that may cause the conveying troughs to contact each other and deform under force can reduce the leakage of the conveyor and reduce the deformation of the conveying trough during transportation, thereby prolonging the service life of the conveying trough and the service life of the conveyor
