Abstract
The utility model relates to a roller screen for industrial production, in particular to a high efficiency cone-shaped roller screen which solves the problem of material accumulation and mesh blocking as materials in the existing roller screen drop slowly. The high efficiency cone-shaped roller screen comprises a screen body; and the screen body has a tapered structure; and the diameter of the front side of the tapered structure is less than that of the back side of the tapered structure; the roller screen is reasonable and reliable in structure design and overcomes the problem of material accumulation; simultaneously the retention period of the materials in the roller screen is ensured; the requirement on complete material screening and fast screening speed is finally realized; and the roller screen has the advantages of simple structure, convenient processing and the like.
Description
Technical field
The utility model relates to the industrial production roller screen, is specially a kind of high-efficiency taper roller screen.
Background technology
Inevitably run into less fine ore of some granularities or feed stock for blast furnace in the industrial production, as coke powder, the iron ore fine ore, manganese ore fine ore etc., and along with international in recent years, constantly riseing of massive price on the domestic market, enterprise begins to use on a large scale fine ore for reducing cost, but owing to have quite a few to be Powdered fully in the fine ore, as go into stove and smelt and to cause that thereby raw material gas permeability difference causes security incident easily in the stove, also have influence on simultaneously product quality, must sieve it in the actual production, and can go into stove after the powder ore deposit made a processing.
Usually can adopt roller screen to sieve in actual production process, common roller screen is to use steel wire by specific mesh specification to be straight-tube shape to roll and make, and rotates the screening that realizes an interior material by driven by motor net tube.But because the net tube is cylindric, owing to blanking velocity causes solid accumulation slowly, thereby block mesh the problem that screening effect is looked into and the screening progress is slow appears in rolling process.
Summary of the invention
The utility model provides a kind of high-efficiency taper roller screen in order to solve the problem that existing roller screen blanking velocity causes solid accumulation slowly and blocks mesh.
The utility model is to adopt following technical scheme to realize: the high-efficiency taper roller screen, comprise sieve nest, and described sieve nest is the cone structure of front side (being charging aperture one side) diameter less than the rear side diameter.During operation, material enters from the front side of sieve nest, increased of the influence of material self gravitation on the basis that utilizes roller screen rotating band animal material screen to divide, in cylinder, pass through speed, overcome the problem that existing roller screen blanking velocity causes solid accumulation and obstruction mesh slowly thereby accelerated material to it.
The utility model reasonable in design is reliable, has overcome the problem of solid accumulation, has guaranteed the time of staying of material in roller screen simultaneously, has realized that finally material screening is thorough, sieve fireballing requirement, has advantages such as simple in structure, easy to process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the 1-sieve nest.
The specific embodiment
The high-efficiency taper roller screen comprises sieve nest 1, and described sieve nest 1 is the cone structure of front side diameter less than the rear side diameter.In the specific implementation process, requirement according to screening raw material size, design circular cone roller screen props up the round steel that holds round with diameter 20 outward, jackshaft uses hollow thick-walled pipe, the round steel that each filtering ring is saved diameter 6 evenly separates, divide the specification that reaches the requirement filtration with this, material loading is to enter feed bin by the forklift material loading, different material piece and the charge levels of each specification of screening after feeding enters roller screen through charging belt, material through screening is falling from feed opening through feeding belt output, waste material is directly handled by forklift, whole machining.
Claims (1)
