Abstract
The utility model discloses a multi-grade roller screen device. At least two parallel rollers form a particle-grade-group; at least two particle-grade-groups are positioned on the rack to form the single layer roller screen; a recovery funnel is arranged under the every particle-grade-group. The device can screen in one time and separate it into powder, small grade, qualified grade and big grade. The device also has the advantages of compact structure, high efficiency, lower production cost and maintenance simple.
Description
Technical field
The utility model relates to many grading rollers screen device that a kind of classifying screen that is used for metallurgical production green-ball and coke is got
Background technology
In metallurgical industry is produced, for improving product yield and quality, often need sieve granule materials, reduce the defective grade that enters next process, and the screening of employing roll screen formula device is the effective way that achieves the above object.Equally, in other industry, also often need the product and the products material of variety classes or different stage be sieved.Roll screen in the tradition is subjected to structural limitations, can only sieve out two kinds of grades of size by the size in gap, material greater than the gap passes through from compass screen surface, and leak down from the compass screen surface gap less than the material in gap, equally also fall within qualified grade district but surpass technological requirement super large grade, to such an extent as to can not effectively the grade that satisfies technological requirement be sieved out.For head it off, existing most of producers adopt double-deck roll screen promptly on former roll screen, add one deck roll screen again.Though twice screening can be satisfied certain requirement, but for narrow space, bring difficulty, but also be the waste problem that the screening of failing to solve many grades causes resource to maintenance work.
The utility model content
The purpose of this utility model is to provide a kind of multistage roll screen device, has compact overall structure, the production efficiency height, and can effectively provide size fractionated simultaneously, avoided the waste of resource.
For achieving the above object, technical solution of the present utility model is finished like this: a kind of many grading rollers screen device, it has, and to be arranged in parallel be a grade group and be at least two individual layer roll screens more than the grade group being provided with two on the frame at least, and set up the recovery funnel separately below each grade group roller sieve.
The technical solution of the utility model also comprises:
The gap of described each grade group roller sieve is adjustable or can not mode.
Good effect of the present utility model is: adopts the individual layer setting, formed the roll screen device of size fractionated, and in limited spatial dimension, finished the material of different grain size sieve has been got, had one-machine-multi-function, used easy and simple to handle, economize on resources, reduce production costs and labour intensity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, to this novel being further described.
By many grading rollers screen device shown in Figure 1, comprise by installing on the frame 6 roll screen 1 that is arranged in parallel by some individual layers is set.This roll screen 1 is provided with at least and is arranged as a grade group more than two, and each grade group is at least more than two grade groups.The utility model has provided 4 grade groups.In order to reclaim varigrained material, and below each granularity group of forming by roll screen 1 classification, be respectively equipped with and reclaim funnel 2 to 5.This classification roll screen 1 is owing to be classified into some screening sections, and each sieves the gap difference of the roll screen 1 of section, can increase successively by its gap of screening section.In addition, the requirement according on using can be adjustable structure to roll screen 1 gap to each other of its each grade group, promptly utilizes at each right roll screen roll screen 1 wherein and is added with slack adjuster.This adjusting device can be utilized conventional realizing by on the roll screen bearing regulating spring being set.But also according to the scope of application of special use, its each roll screen 1 location, each grade of setting the gap being remained unchanged be can not mode-structure.
The formation of said apparatus, powder, little grade are sifted out in the gap that anterior grade screening section adopts, leak down required qualified grade successively and collect in the setting gap of grade screening section successively subsequently, the underproof big grade of this screening section is sieved section by entering down the road from compass screen surface, so far all reclaim, thereby reach one deck roll screen carries out many gradation sizings to material purpose.
Claims (2)
1, a kind of many grading rollers screen device, comprise frame and go up the roll screen that is provided with, it is characterized in that being provided with at least on described frame (6) two, to be arranged in parallel be a grade group and be at least two individual layer roll screens (1) the grade group more than, and set up recovery funnel (2-5) below each grade group roller sieve (1) separately.
2, by the described many grading rollers screen device of claim 1, the gap that it is characterized in that described each grade group roller sieve (1) is adjustable or can not mode.
