Description
Technical field
The utility model relates to a kind of coal, ore classifying equipoment, especially relates to comb classification gravity flow screen subset.
Background technology
The method for sieving that ore dressing both at home and abroad at present and coal separation are commonly used and screening plant thereof have: vibratory sieve, shaker screen, roller picker, spiral screen etc.Also have a kind of gravity flow screen, its compass screen surface tilts to install, and material flows through above compass screen surface, and the material being greater than sieve aperture is slipped to bottom, under the material being less than sieve aperture falls compass screen surface through sieve aperture.Aforesaid way can reach comparatively ideal effect in the little situation of material moisture.But when relatively being wet by sieve material and containing certain mud (adhesional wetting materiel), sieve aperture easily blocks, and does not reach desirable effect.
Utility model content
The purpose of this utility model is to provide one can complete stock grading, simultaneously the comb classification gravity flow screen subset of self-cleaning sieve seam.
In order to achieve the above object, the technical solution of the utility model is to provide a kind of comb classification gravity flow screen subset, is provided with comb, and it is below the compass screen surface be made up of multiple castor bars at interval, the sieve formed between adjacent castor bar that interts stitches, and reaches on compass screen surface through sieve seam; Be connected described comb and reductor by arranging circumversion chain with sprocket system, the running of this reductor drives comb to move along screen length direction thus clears up sieve seam.
Described compass screen surface tilts to install, when material moves downward on compass screen surface, the material being greater than sieve seam flows through and is slipped to one end of screenings chute, is slipped to the other end of screenings chute under the material being less than sieve seam falls compass screen surface through sieve seam, in material movement process, completes classification.
Preferably, the diverse location on screen length direction, the gap forming sieve seam between adjacent castor bar is different.
Described circumversion chain and sprocket system, comprise further:
At the chain that the both sides of compass screen surface width are arranged respectively, each chain is around on a drive sprocket and a driven sprocket, and described drive sprocket and driven sprocket lay respectively at the two ends in screen length direction; Connected by a shaft coupling between two drive sprockets, connected by another shaft coupling between two driven sprockets;
Described comb is arranged across compass screen surface width below compass screen surface, and is connected on chain.
Described reductor is connected to the shaft coupling of wherein side drive sprocket, makes each sprocket wheel, each chain rotates with reductor, and then drives comb motion.
Preferably, on described chain, interval is furnished with several comb, and these comb are inserted into the sieve seam being arranged in diverse location on screen length direction simultaneously.
Compared with the prior art, comb classification gravity flow screen subset described in the utility model, fully shows following advantage:
1. consume energy low, additional structure is simple;
2. flexible arrangement, screening efficiency is higher, and the castor bar that can arrange different gap in different section reaches the object of many gradings.
3. the adhesional wetting materiel between castor bar is cleared up, the inaccessiable effect of existing screening plant can be obtained.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the comb classification gravity flow screen subset that the utility model provides, forms compass screen surface by multiple castor bars 1 of inverted trapezoidal section, and this compass screen surface tilts to install; Space between adjacent castor bar 1 forms sieve seam, and when material moves downward on compass screen surface, the material being greater than sieve seam flows through and is slipped to one end of screenings chute; Under being less than the material of sieve seam seam falling compass screen surface through sieve, and be slipped to the other end of screenings chute, in motion process, complete classification.Can make the castor bar 1 being positioned at diverse location on screen length direction, its adjacent gap is different, and such as, at motion process leading portion, the gap of castor bar 1 is little; More to motion process back segment, the gap of castor bar 1 is larger, thus reaches the object of many gradings.
The utility model is also provided with comb 2, and be that it is equipped with circumversion chain and sprocket system separately: as shown in Figure 5, the both sides of compass screen surface width are respectively furnished with a chain 3, each chain 3 is around on a drive sprocket 41 and a driven sprocket 42, and drive sprocket 41 and driven sprocket 42 lay respectively at the two ends in screen length direction; Connected by a shaft coupling 5 between two drive sprockets 41, connected by another shaft coupling 5 between two driven sprockets 42.Comb 2 is arranged across compass screen surface width, and is connected on chain 3; Make comb 2 from interting below compass screen surface between adjacent castor bar 1, and reach on compass screen surface through sieve seam; Several comb 2 can be arranged in interval, to clear up diverse location on compass screen surface simultaneously on chain 3.
As shown in Fig. 4, Fig. 5, Fig. 6, be provided with reductor 6 in the utility model, such as, be connected with the shaft coupling 5 of wherein side drive sprocket 41, make each sprocket wheel 4, each chain 3 rotates with reductor 6, and then drive comb 2 to move through castor bar 1 above, play the effect of defeated logical sieve seam.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
