Sintering machine tail feeding channel

Abstract

The invention relates to a sintering machine tail feeding channel, and belongs to the technical field of sintering production equipment in the metallurgical industry. According to the technical solution, the feeding channel comprises a material chute (5) and a base (6), and the material chute (5) is fixed to the base (6); the material chute (5) is formed by combination of a back plate (12), two side plates (13) and a bottom plate (14), the material chute (5) is internally and successively provided with a plurality of material discharge pockets (9) from top to bottom, and the multiple materialdischarge pockets (9) form a multi-level trapezoid, the back plate (12) inside the material chute (5) is provided with a back plate buffer material bag (10), and a side plate (13) inside the materialchute (5) is provided with a side plate buffer material bag (11); and the back plate (12) outside the material chute (5) is provided with a material receiving chute (7). The feeding channel has the beneficial effects that production process requirements are met, wear resistance and impact resistance are achieved, the service life is two years or above, sinter can be fallen smoothly to a single roll crusher, and the operation rate of the sintering machine is improved.

Description

technical field [0001] The invention relates to a material guide groove at the tail of a sintering machine, which belongs to the technical field of sintering production equipment in the metallurgical industry. Background technique [0002] The tail guide groove of the sintering machine is located between the tail of the sintering machine and the single roll crusher. It is one of the most important links in the sintering production line, and its reliability is crucial to the stability of the entire sintering production. Usually, the relative height difference between the table top of the sintering machine and the trolley surface of the single-roller crusher is greater than four meters. It can reach seven tons, the drop can reach three meters, and the impact force is quite large. The discharge end has been scoured by high-temperature sintered ore for a long time, causing serious wear and tear. Moreover, the material guide groove works continuously at high temperature for 24 h...

AI Technical Summary

Problems solved by technology

Usually, the relative height difference between the table top of the sintering machine and the trolley surface of the single-roller crusher is greater than four meters. It can reach seven tons, the drop can reach three meters, and the impact force is quite large. The discharge end has been scoured by high-temperature sintered ore for a long time, causing serious wear and tear.

Moreover, the material guide groove works continuously at high temperature for 24 hours, which accelerates the wear of the equipment and leads to a short service life.

In particular, the upper square steel and the lower square steel of the guide trough are easily impacted by hot sintered ore, and the wear is the most serious. They need to be adjusted every three months and replaced every six months.

Every overhaul from shutdown, material cleaning, to welding repair, disassembly and replacement is time-consuming and labor-intensive, which seriously affects the operation rate of the equipment

It also increases the cost of the equipment, so there is an urgent need for a material guide trough that prolongs the service life
