Description

Automatic adjusting strike-off board for muller

The utility model is a kind of puddle mixer with automatic adjustable type scraper plate.

At present, in all kinds of puddle mixers, all exist the problem that influences production because of the scraper plate quick abrasion.Tracing it to its cause, is because this kind scraper plate is the stationary structure of an entire plate, and it is with puddle mixer base plate position contacting with apart from can not regulating.So it can not be wiped the scab that is positioned at puddle mixer base plate and wallboard recess off and in time stop like the similar snowball scab to be heaped, and can not sustain caused thus increasing frictional resistance well.In order to prolong the service life of scraper plate, the possessor uses the monoblock scraper plate wear resistant cast iron instead or welds carbide alloy in the bottom of scraper plate to the greatest extent, but this do not seek medical advice this remedial measure of table of controlling still makes the MaLS of scraper plate also can only rest on about four months.In addition, owing to can not eradicating reason---the scab that makes scraper plate wearing and tearing, so, this not only makes the power consumption of puddle mixer increase, and in process of production, the workman must often creep into puddle mixer cleaning scab, both taken the production time, and influenced production efficiency, labor strength is also big.

The purpose of this utility model is the problem at above-mentioned existence, provides a kind of improved puddle mixer with automatic adjustable type scraper plate.This scraper plate is when work, and energy self-regulated does not produce scab, and long service life.

The purpose of this utility model is achieved in that within it, the lower edge of the main body of outer scraper plate, be provided with 1-4 root arc bar, and every bar is fixed at the bottom of two springs on the push rod on the adjuster, a spring side adjuster is fixed on the main body top of outer scraper plate, and the piece that to be fixed with a working face on its push rod be arc.

The structure of above-mentioned end adjuster can be: in the thick cavity of its cover, go up certainly by be equipped with successively down lid that screw thread with it links to each other, with the spring that the push rod head end interlocks, the Kong Houyu bar weldering that the following body of rod of the push rod shaft shoulder then passes thick cavity bottom connects.

The structure of above-mentioned side adjuster can be: in the thick cavity of cover, the briquetting, the push rod that are arranged with lid and are interlocked respectively with both ends of the spring by the right side from a left side, its push rod shaft shoulder connect with the piece weldering after then passing the hole of the thin cavity of cover and lid with the body of rod on the right side.Above-mentioned left and right two lids all link to each other with external threading, and bolt is contacted with briquetting by left worker's lid.

Because it is the automatic adjustable type structure of elasticity that the utility model is changed fixed, so following advantage is arranged:

One has been eradicated the condition that forms scab.This is because under the pressure of the end, side adjuster, the result that bar and piece are kept in touch with the chassis and the sidewall of puddle mixer all the time well.

Its two, be easy to manufacturing, economy and long service life.This is because it is simple in structure, and has eliminated the inevitable outcome that itself and the hidden danger (being scab) of chassis wearing and tearing are brought.

Its three, be easy to existing fixed formula scraper plate is transformed, prolonging its service life and to save the operation of the removing scab of high labour intensity, thereby help enhancing productivity and reducing production costs.

Its four, help reducing the power consumption of puddle mixer, and it is also higher to mix the molding sand quality of system.

In a word, the utility model has overcome defective of the prior art, has brought positive positive effect.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.

The utility model comprises the inside and outside scraper plate 20,21 of arc.

The structure of inside strake 20 as shown in Figure 1 and Figure 2: its main body 3 is arc entire plate, in the lower edge of plate, is provided with three arc bars 1 that match with it.The push rod 10(that bar 1 is welded on end adjuster 2 sees Fig. 5) go up or directly be embedded in the open slot of push rod 10, and every bar 1 can be by adjuster 2 clampings at the bottom of two.End adjuster 2 can be fixed on the main body 3 with bolt or spot welding mode.

As shown in Figure 3, Figure 4, the structure of outer scraper plate 21 is: its main body 6 also is an arc entire plate, is equipped with on its plate and identical bar 1 of inside strake and end adjuster 2, on its left end and bar 1, a side adjuster 5 is installed also.Piece 4 is fixed by bolts on the supporting plate 7, and 7 of supporting plates are with bolt or be weldingly fixed on the open slot of push rod 18 of side adjuster 5.Piece has a curved working face, is beneficial to piece and contacts with the wallboard of puddle mixer.

As Fig. 5, shown in Figure 6, the structure of end adjuster 2 is: a cover 11 is arranged, and the cavity of cover 11 is upper coarse and lower fine.In thick cavity: the shaft shoulder of push rod 10 rests on the thick cavity bottom outlet, and its shaft shoulder top is with spring 9, seals with the lids 8 that link to each other with cover 11 weldering connection or screw thread again.The following body of rod of push rod 10 shaft shoulders then passes bottom outlet and bar 1 weldering connects or embedding connects.

As shown in Figure 7, the structure of side adjuster 5 is: in the thick cavity of cover 15, spring 14 is arranged, spring 14 two ends are enclosed within respectively on the nose of push rod 18, briquetting 19.The other end of briquetting 19 leans against on the lid 13 that links to each other with thick cavity mouth end screw thread, and contacts with the bolt 12 that covers.Pressure with bolt 12 adjustable springs 14.After passing in the hole of the body of rod of push rod 18 by cover 15 thin cavity and sealing ring 17, lid 16, link to each other with supporting plate 7.Lid 16 links to each other with cover 15 screw threads.

Fig. 8 has shown the installation position of inside and outside scraper plate 20,21 in puddle mixer, the same prior art of installation requirement.Sequence number 22,23 and 24 is crosshead, muller and main shafts of puddle mixer.

When puddle mixer is worked, if on its chassis scab is arranged, the push rod 10 of the end adjuster 2 on the so inside and outside scraper plate 20,21, under the effect of spring 9, can be automatically according to the variation (place that scab is arranged of external force, resistance is bigger) carry out upper and lower adjusting, change the spacing between certain root bar 1 and the chassis, thereby scab is removed.In like manner, if on its sidewall scab is arranged, the push rod 18 of the side adjuster 5 on the so outer scraper plate 21 under the effect of spring 14, also can carry out left and right adjusting according to the variation of external force automatically automatically, changes the spacing between piece 4 and the sidewall, so that remove scab.

In a word, the utility model all can not make on the chassis of puddle mixer or the sidewall residual " scab ", and the mulling function is normally worked down.
