Problems solved by technology

When sampling the existing blast furnace, only one sample can be taken from one tuyere, and the actual temperature in the furnace cannot be measured. In view of the current difficulties, there is an urgent need for an electromechanical device that can safely take samples in the furnace and actually measure the high temperature in the furnace during the production of the blast furnace. Improve blast furnace productivity
In addition, when the blast furnace is produced with wind, when the furnace condition is not good, it is necessary to feed a small set of materials to the tuyere to block the tuyere. At present, the only way to block the tuyere is to stop the production by shutting down the wind. Therefore, it is urgent to Only by feeding with wind to block the tuyere and opening the tuyere with wind can the production efficiency of the furnace be improved

Abstract

The invention relates to a real-time air taking and conveying device and method used in a blast-furnace tuyere in the metallurgical ironmaking process, and belongs to the technical field of machines.The device structurally comprises a rail, a chassis walking mechanism, front and rear chain seats, a rack and an air taking and conveying system. A temperature measurement display is arranged on achassis, the bottom of the rack is fixed on the chassis; a guide rail mechanism parallel to the rail and used for guiding the air taking and conveying system to move is arranged at the top of the rack, the air taking and conveying system comprises a taking and conveying pipe capable of moving in the guide rail mechanism, the tail end of the taking and conveying pipe is connected with a sample tank ora feeding tank through a control valve, and the top end of the taking and conveying pipe enters the blast furnace tuyere small sleeve through a smelting furnace measuring controller and a blowpipe. The method has the beneficial effects that real-time analysis of solid, gas and temperature in the furnace in the blast furnace production process is fully achieved, air blocking with wind, air openingwith wind and material spraying in the blast furnace are fully achieved, the purposes of saving energy and increasing yield are achieved, the blast furnace production efficiency is improved, the costis reduced, the domestic technical blank is filled up, and the world advanced level is achieved.

Description

technical field [0001] The invention relates to a real-time air extraction system for blast furnace tuyeres in the metallurgical ironmaking process. [0002] The invention relates to a delivery device and a delivery method, in particular to a blast furnace tuyere belt delivery machine and a delivery method, and belongs to the field of mechanical technology. Background technique [0003] At present, when the blast furnace is in normal production, it is impossible to sample and analyze the inside of the furnace. The existing blast furnace tuyere sampling device cannot effectively control the high temperature of 2500°C and the temperature of 4-6kg / cm2 in the blast furnace. 2 The pressured gas and furnace charge are sprayed out, and samples can only be taken when the wind is off, so that the samples cannot fully reflect the situation in the furnace. The applicant applied for "a furnace measurement controller and measurement control method" on 2016.07.18, patent number 201610567...
