Description

Wear-resistant adjustable bellows flap valve for sintering machine

Technical Field

The utility model relates to a wear-resisting adjustable bellows flap valve for sintering machine.

Background

The sintering process of the belt type sintering machine is completed by means of the ignition combustion of the sintering mixture under a certain negative pressure condition to generate a physical and chemical reaction, generally, an air exhaust section under a sintering machine trolley keeping a certain negative pressure condition is designed to be composed of a plurality of air boxes, different requirements are provided for the negative pressure conditions of different air box sections, and an adjustable air box flap valve of a flue sealing system of the sintering machine is used for adjusting and controlling the negative pressure of different air boxes in the sintering process so as to meet the requirements of the sintering process. The main problems of the prior art of the sintering machine air box flap valve are that poor abrasion resistance easily causes air box sealing failure due to body abrasion and air leakage, poor lubrication condition of a flap rotating shaft bearing part is poor, bearing damage failure easily occurs, poor flap sealing performance caused by design reasons is caused, and the like, so that a large amount of air leakage is generated due to air box flap position sealing failure, the flap rotating shaft bearing is dead due to poor lubrication and flap sealing causes flap abrasion seriously to cause adjustment failure and the like, and great influence is caused on sintering production stability and equipment operation.

Disclosure of Invention

The utility model aims at providing an bellows flap valve with adjustable wear-resisting that sintering machine was used can solve the adjustable bellows flap valve of sintering machine and do not stand wear and tear, turn over lubricated bad and the poor problem of board seal of board pivot bearing, reduce bellows by a wide margin and turn over board position seal failure and produce a large amount of air leakages, turn over board pivot bearing because lubricated bad card is dead and turn over board seal bad and cause to turn over board wearing and tearing seriously and cause and adjust the inefficacy scheduling problem.

The utility model provides a, bellows flap valve with adjustable wear-resisting that sintering machine was used, including the valve body, this internal valve shaft that is setting up of valve and installing the board that turns over on the valve shaft, setting up the wear-resisting square steel of annular that the specification is 100X100mm on the top internal perisporium of valve body, the symmetry is setting up the triangle-shaped gusset on the square steel bottom surface and the internal perisporium of valve body, valve shaft tip outside-in coordinates the suit in proper order and is setting up gland and end cover, constitutes ring shape lubrication chamber between end surface and the valve shaft outer peripheral face in end cover internal perisporium and the gland, the intussuseption of lubrication chamber is being set up solid-state graphite emollient, be the face.

The utility model discloses increasing wearing parts at key wearing and tearing position on the former design basis of bellows flap valve with adjustable original sintering machine, having cancelled and turned over board main shaft bearing, change into on the main shaft lug connection axle sleeve and sealed with the gland, cavity between valve shaft and the end cover uses solid-state graphite lubrication seal lubrication, can keep no longer needing the outside lubrication of refueling within 3 years at least. The utility model discloses compare with original technique and can reduce the phenomenon of leaking out that causes because the body wearing and tearing of adjustable bellows flap valve of sintering machine can be by a wide margin, stop completely because the lubricated bad board main shaft bearing that turns over that causes of board main shaft bearing damages or blocks dead phenomenon and improve by a wide margin and turn over the board leakproofness, reduce because the poor wearing and tearing that cause of board leakproofness turns over, increase sintering machine flue system's gas tightness, improve sintering machine bellows negative pressure regulation efficiency by a wide margin, reduce by a wide margin because the maintenance volume that each position wearing and tearing of flap valve caused with adjustable sintering machine bellows improve the effective operation rate of sintering machine and improve sintering.
