Embodiment Construction

[0031] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention will now be described with reference to the accompanying drawings.

[0032] Such as figure 1 As shown, the sintering trolley bottom material classification distribution device of the present invention comprises:

[0033] Ring cooler; process sinter bottom material with a certain size and thickness;

[0034] The cold screen is arranged downstream of the annular cooler and connected to the outlet of the annular cooler; the grain size of the cold screen is 16mm, and the sintered ore of a certain grain size and a certain thickness processed by the annular cooler is filtered, and the granular The bottom material with a diameter of more than 16mm is filtered out and sent to the sintered product bin; the bottom material with a particle size of less than 16mm is filtered out and sent to the secondary material sieve;

[0035] The secondary ma...

Abstract

The invention discloses a sintering pallet grate-layer material grading material arrangement device and method. The sintering pallet grate-layer material grading material arrangement device comprisesan annular cooler, a cold screen, a second level material screen, a grate-layer material screen, a grate-layer material bin, a partition plate and a sintering pallet, wherein the annular cooler is arranged on the upstream of the cold screen, the cold screen is arranged on the downstream of the annular cooler, and connected with an outlet of the annular cooler, the granulometric class of the cold screen is 16 millimeters; the second level material screen is arranged on the downstream of the cold screen, the granulometric class of the second level material screen is 5 millimeters; the grate-layer material screen is arranged on the downstream of the second level material screen, the granulometric class of the grate-layer material screen is 12 millimeters; the grate-layer material bin is arranged below the second level material screen; the partition plate is arranged in the grate-layer material bin; the sintering pallet is arranged below the grate-layer material bin; and the distance amongan outlet of a coarse fraction bin, an exit of a fine fraction bin and the sintering pallet is greater than zero. The method adopts the sintering pallet grate-layer material grading material arrangement device. The material arrangement is more even and smooth, the filtration is enhanced, and the content of flue gas and dust is reduced.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a device and method for grading and distributing bottom materials of sintering trolleys, which are used for grading and distributing sintered ore on sintering trolleys. Background technique [0002] At present, most manufacturers at home and abroad use part of sintered ore (10-16mm or 5-16mm) as the base material. Spread a layer of sintered ore with a certain size and thickness on the grate of the sintering trolley as the bottom material, which can protect the grate and reduce the spillage of bulk materials; enhance filtration and reduce the content of flue gas dust; maintain an effective ventilation area , to make the air flow evenly distributed, improve the vacuum system of the sintering process; improve the air permeability of the sintering process, and increase the sintering productivity. [0003] However, the following problems exist in the prior art: the sintering efficiency is p...
