Individual sieve chamber is also shed to increase current sieve effect thoroughly with the motion to ore pulp, and the cavity thickness of three sieve chambers can be with rocked position
Difference and change, chamber thickness is changed from small to big and can attract ore pulp from ortho position sieve chamber, and chamber thickness from large to small can squeeze ore pulp at past ortho position
Sieve and presses to screen cloth at chamber, the ore pulp for thus allowing for sieving intracavitary is stirred, it is saturating on one side sieve, while move down, and do not sieve thoroughly
Material is constrained on sieve intracavitary and agitated, and the ore pulp of sieve intracavitary can be mixed well without spilling, and only sieve just can go out to sieve chamber thoroughly.Will
Three sieve chambers deposited the lower compass screen surface for having material after an one-stroke is waved, originally and are transformed into compass screen surface, and did not deposited originally
The upper compass screen surface of material is transformed into lower compass screen surface, through this compass screen surface rotation, makes thin liquid pulp towards lower compass screen surface, this can just be avoided solid accumulation
And influence sieve thoroughly.As moving down for material is gathered in sieve cavity combining body, the change for still having sieve chamber thickness can make top sieve the dilute of chamber
Ore pulp is poured into the dense ore pulp of bottom sieve chamber, although now screening may continue to, screening slows；And will sieve box it is multiple on
Lower upset can just increase movement travel of the material on compass screen surface, make screening speed recover to accelerate.
Compared with existing testing screen (sieve) point utensil, the beneficial effect that folding sieve is hung in experiment of the present invention with stay-supported is：
（1）There are the means of two kinds of raising screening efficiencies, one is the ore pulp layer for pulling turn sieve intracavitary with left and right rotation, two
It is that sieve box is spun upside down to the movement travel to increase material on compass screen surface so that screening speed is fast, and screening precision is high；
（2）Exempt from power supply, utensil low cost, the screening process sound is small；
（3）Charging and feeding are convenient, and the hand of operating personnel can be stained with a small amount of ore pulp once in a while only in charging and feeding,
Screening process hand is clean, and its operating process is light as playing toy for children；
（4）Consumable accessory is bracing wire and covered every slurry that the price accounting of consumable accessory is low, and is convenient to self-changeable.
