Abstract

The utility model discloses a blaster box valve of a sinter machine with simple structure and very small occupying space. The blaster box valve of the sinter machine comprises a valve enclosure and a valve plate arranged inside the valve enclosure. The valve plate is provided with a rotating shaft, the end of which close to the external side of the valve enclosure is provided with a rotating handle; the end part of the rotating handle is connected with an output shaft of a driving device.

Description

The sintering machine wind box valve

Technical field

The utility model relates to the sintering machine apparatus field, relates in particular to the sintering machine wind box valve.

Background technique

Sintering machine wind box is one of vitals of sintering machine, and the igniting and the sintering of the mixing material (containing grate-layer material) on the sintering pallet need could carry out under the effect by sintering machine wind box exhausting formation negative pressure smoothly.The hot blast that produces in the sintering process is taken away through the main exhauster that bellows arm and large flue are sintered machine, and fines that falls down from chassis and dust also enter large flue through the bellows arm, so the bellows arm (can reach 450 at high temperature.More than), environment such as negative pressure has a large amount of fineves and dust to pass through in work and the arm down.The sintering machine wind box arm is made up of bellows, bellows valve, reducer pipe compensator and pipeline etc., and a sintering machine contains a plurality of bellows arms.The sintering machine wind box valve is a vitals in the sintering machine wind box arm, valve plate angle by control bellows valve, can regulate exhausting vacuum magnitude in the sintering machine wind box and the required air quantity size of sintering process, to satisfy the bellows air quantity under the igniter and the adjusting requirement of little negative pressure, realize control to sintering process and sintering quality.The driving mode of existing bellows valve has manually and electronic two kinds of patterns.Manual drives is seldom used now because of not satisfying the requirement of automatic control; As shown in Figure 1, the bellows valve of motorized motions mode is controlled the switch of valve by execution device such as more piece connecting rod, electric actuator and power plant, and its shortcoming is: each valve links to each other by the more piece connecting rod, mechanism's complexity, and it is bigger to take up room; Have a plurality of articulating points between connecting rod and the valve, increase the fault point, and maintenance workload increases; When the jam phenomenon appearred in a valve, the opposite side corresponding valve can not normally open and close; The sectional shape of bellows valve has only rectangle this is a kind of in addition.

The model utility content

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, take up room the sintering machine wind box valve minimum.

Sintering machine wind box valve of the present utility model, comprise valve housing and be installed in the interior valve plates of valve housing, valve plates is provided with rotating shaft, and the end that rotating shaft is positioned at the valve housing outside is provided with handler, and the end of described handler links to each other with the output shaft of a drive unit.

Described drive unit is installed on the bellows arm by bearing, and the fuselage and the bearing of drive unit are hinged.

Described drive unit is electric pushrod or Electrohydraulic push rod or electric cylinder.

Compared with prior art, advantage of the present utility model just is: each bellows valve is provided with independent drive unit, has removed complicated more piece linkage mechanism, and taking up room reduces, and the probability that breaks down reduces; When certain bellows valve can't proper functioning, only need overhaul to the bellows valve that goes wrong, need not check the bellows valve of opposite side correspondence, save the repair time, saved the labour force, improved working efficiency; When the jam phenomenon appearred in a bellows valve, other valve can also normally open and close; The fuselage and the bearing of drive unit are hinged, stuck phenomenon occurs when can effectively prevent to promote handler, make transmission more smooth.

Embodiment

As Fig. 2, Fig. 3, shown in Figure 4, sintering machine wind box valve of the present utility model, comprise valve housing 1 that is installed on the bellows arm 4 and the valve plates 2 that is installed in the valve housing 1, valve plates 2 is provided with rotating shaft 21, the end that rotating shaft 21 is positioned at valve housing 1 outside is provided with handler 22, be equiped with drive unit 3 on the bellows arm 4, the output shaft 31 of drive unit 3 links to each other with handler 22, and drive unit 3 is an electric pushrod in the present embodiment.After adopting structure of the present utility model, the bellows valve has been removed complicated more piece linkage mechanism, and taking up room reduces, and the probability that breaks down reduces; When certain bellows valve can't proper functioning, other valve can also normally open and close, and only needed overhaul the bellows valve that goes wrong, and need not check other bellows valve, had saved the repair time, has saved the labour force, had improved working efficiency.Drive unit 3 is installed on the bellows arm 4 by bearing 5, and the fuselage of drive unit 3 and bearing 5 are hinged, stuck phenomenon occurs when can effectively prevent to promote handler, makes transmission more smooth.

Present embodiment provides drive unit 3 to be the mode of execution of electric pushrod, and drive unit 3 also can adopt Electrohydraulic push rod or electric cylinder, and this type of conversion all should drop within the protection domain of the present utility model.
