Abstract

The utility model discloses a spiral screening plant wholly is the heliciform, adds the section by support, base, pan feeding mouth, spiral main part, minus sieve material collecting pipe, plus sieve material bin outlet, screen cloth, support iron bar and spiral main part and forms. The support is fixed on the base, and the spiral main part props the iron bar through a plurality of spinal branchs and welds on the support, and the pan feeding mouth is in spiral main part upper end. The spiral main part is two -layer, and middle screen cloth with laying separates, and screening material gets into the upper strata from the pan feeding mouth, and the lower floor is confined minus sieve material collecting vat. A plurality of minus sieve material collecting pipes are equipped with to minus sieve material collecting vat bottom for collect the minus sieve material, the plus sieve part is discharged from the plus sieve material bin outlet of spiral main part lower part. Be provided with the spiral main part that is used for increasing spiral length simultaneously and add the section, can connect at spiral screening plant through bolted construction terminal, make full use of the factory building space, reduced the screening cost, reduced the capital expenditure.

Description

Spiral screening plant

Technical field

The utility model is related to a kind of screening plant, more particularly to a kind of wet screening device of coal separation ore dressing field.

Background technology

In coal separation ore dressing process, screening is a requisite link, can be used to being classified, is dehydrated, de-mediated and desliming Deng.Efficient screening plant can improve the classification efficiency of mineral, and then improve the separating effect of mineral；Meanwhile, efficient sieve Divide and cause the dehydration desliming effect of product more significantly, be conducive to improve product quality, meet user's requirement.But, current institute Screening plant floor space is big, limits the increase of sieving area, meanwhile, want the disposal ability for increasing screening plant, The number of units of screening plant will be increased, the efficiency of screening will be not only limit, the raising of screening cost will be also resulted in, a large amount of factory buildings will be taken Space, increased capital expenditure.

The content of the invention

The purpose of this utility model is to provide a kind of screening efficiency height, makes full use of hall space, reduces capital expenditure, drop The spiral screening plant of low production cost.

The technical solution of the utility model is：A kind of spiral screening plant, it is overall in the shape of a spiral, including support, base, Feeding mouth, helical body, undersize material collecting pipe, on-the-sieve material discharge gate, screen cloth, support iron staff and helical body addition section group Into.Support is fixed on base, and helical body supports iron staff to be welded on support by some, and feeding mouth is in helical body End.Helical body is two-layer, and the screen cloth of centre laying separates, and screening materials carrying enters upper strata from feeding mouth, and lower floor is closing Undersize material feeder.Undersize material collects trench bottom and some undersize material collecting pipes is housed, for collecting undersize material, sieve Discharge from the on-the-sieve material discharge gate of helical body bottom upper part.The helical body for increasing helix length is provided with simultaneously Addition section, can be bolted in screw sieving device end, when feeding coal increases, sieving area be increased, at raising Reason ability.

The beneficial effects of the utility model：Spiral screening plant described in the utility model, screening efficiency is high, fully profit With hall space, screening cost is reduced, reduce capital expenditure.

Fig. 2 is helical body double-layer structure schematic diagram.

Fig. 3 is that helical body adds section schematic diagram.

Specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail, but is not to limit the utility model.

Referring to accompanying drawing, the spiral screening plant of the utility model, including support 1, base 2, feeding mouth 3, helical body 4, Undersize material collecting pipe 5, on-the-sieve material discharge gate 6, screen cloth 7, support iron staff 8 and helical body addition section 9 are constituted.Support 1 is consolidated It is scheduled on base 2, helical body 4 supports iron staff 8 to be welded on support 1 by some, and feeding mouth 3 is in the upper end of helical body 4.Spiral shell Rotation main body 4 is two-layer, and the screen cloth 7 of centre laying separates, and screening materials carrying enters upper strata from feeding mouth 3, and lower floor is the sieve of closing Lower material collection groove.Undersize material collects trench bottom and some undersize material collecting pipes 5 is housed, for collecting undersize material, sieve Discharge from the on-the-sieve material discharge gate 6 of the bottom of helical body 4 upper part.The spiral master for increasing helix length is provided with simultaneously Body adds section 9, can be connected to screw sieving device end by bolt arrangement 10, when feeding coal increases, increases screening surface Product, improves disposal ability.When device works, material is entered in helical body 4 on sheaf space, i.e. screen cloth 7 from feeding mouth 3, and Helix on screen cloth 7 along helical body 4 is moved downward, in motion process, material of the granularity less than the screen size of screen cloth 7 Into the lower floor of helical body 4, and discharge from undersize material collecting pipe 5；Granularity is more than the material of the screen size of screen cloth 7 from spiral master The on-the-sieve material discharge gate 6 on the upper strata of body 4 is discharged.When feeding coal increases, helical body addition section 9 can be connected with bolt arrangement 10 The end of helical body 4 is connected to, increases sieving area.
