Technical field
The invention belongs to gravitational field preparation equipment technical fields, are related to a kind of low abrasion lump ore gravity separation sorting machine.
Background technique
Lump ore dense medium separation is the highest beneficiation method of sharpness of separation in current gravity separation, and dense medium separation method exists
Coal field is widely applied, and in most coal preparation plants of China, lump coal separation machine is main screening installation, according to highly dense
The difference for spending product means of transportation is divided into vertical wheel, tiltedly wheel and scraper plate sorting machine for user's selection.
The main beneficiation method of ore dressing field be with grind it is floating based on, lump ore purpose higher to some degree of dissociation of mineral monomer
The grade of mineral reach market demands picking can be used or mechanically decoupled method is sorted.Picking is suitable for big lump ore
Stone, and the grade of blocky target minreal is higher, the unstable product quality that this method obtains, low output.Lump ore is mechanically decoupled
Method mainly has photoelectricity identification sorting, ray identification sorting, gravity separation method.Photoelectricity identification separating method be using target minreal with
The surface texture difference of non-target minreal and realize sorting, sharpness of separation depend on difference size and granule size, meet this
The ore of difference is seldom, there is significant limitation in this way；Ray method of identification is strong to the reflection of ray using ore
Degree calculates its density, using executing agency by ore by calculating Density Separation, treating capacity lesser item larger suitable for granularity
Part, and sharpness of separation is to be improved.Gravity separation method includes jigging method and sink and float method, and the sharpness of separation of jigging method is poor, lump ore
Sink and float method sharpness of separation is high, and treating capacity is big, the disadvantage is that serious wear, maintenance workload is big.Our company once with the more Rui Make in Wuxi
Excessively a kind of lump ore heavy-media separator of skill Co., Ltd joint research and development ore dressing field promote and apply, effect is fine, it is insufficient just
It is scraper plate and body inclined bottom plate serious wear, has carried out multiple improvement in material and structure of the site of deployment to this equipment, but
The effect is unsatisfactory.
Summary of the invention
In view of the above-mentioned problems, providing a kind of low abrasion lump ore gravity separation sorting machine, which was both able to achieve the present invention
High-precision sorting is again extremely durable.
A kind of technical solution according to the invention: low abrasion lump ore gravity separation sorting machine, it is characterised in that: including machine

Scraper chain bend wheel is set, scraper chain tensioning is set to the scraper chain driving wheel, tension device for scraper chain and scraper chain bend wheel
On；
Body includes flat bottoms and wedged bottom portion, and the lower part trend of scraper chain is arranged along flat bottoms, wedged bottom portion, corresponds on body oblique
High density material outlet is arranged in the outer end of bottom, and overflow port is arranged in the upper position that hollow cavity is corresponded on body.
As a further improvement of the present invention, the tension device for scraper chain includes the balladeur train being fixed on the frame body of top,
Sliding block is snug fit on the sliding rail of balladeur train, and rotation setting tensioning wheel, sliding block are fixedly connected with adjusting screw rod, the adjusting on sliding block
Screw rod is threadedly engaged with balladeur train and connect.
As a further improvement of the present invention, upper up-flow medium inlet is arranged in the flat bottoms, and upper up-flow medium inlet connects
Logical body hollow cavity.
As a further improvement of the present invention, the hanging plate chain includes round-link chain and scrapes with what the round-link chain was connected
Plate, the scraper plate are provided with hole.
As a further improvement of the present invention, the scraper chain driving wheel is corresponded on the frame body of top and scraper chain tensioning fills
Scraper chain support roller is set between setting, and scraper chain support roller is used for support scraper chain.
As a further improvement of the present invention, at work, body (1) hollow cavity is filled with heavy-media suspension, dense medium
Liquid level high density material outlet (11) 200 ~ 400mm of distance of matter suspension.
The technical effects of the invention are that: when product of the present invention works, hypostasis scrapes liquid level in very short wedged bottom by scraper plate
High density material outlet is just fallen in portion after de-mediated, the chance that particle is blocked between scraper plate lower edge and body wedged bottom portion drops significantly
It is low；After scraping plate spacing expansion, the chance that scraper plate is contacted with organism bottom is reduced；Using scraper plate lower edge and body after T-type scraper plate
The gap of bottom remains in defined section.These improvement reduce abrasion, the body wedged bottom portion of scraper plate lower edge jointly
Abrasion, scraper plate chain guide abrasion, substantially prolong the service life of this equipment, reduce use cost.The height of stock guide
It is the position for changing material and entering sorting machine that degree, which is adjusted, on the one hand can adjust material in the machine intracorporal sorting time, on the other hand
The drop point of hypostasis can be changed, place scraper plate unbalance loading, reduce abrasion.
