Abstract

The invention discloses a self-adaptive control hammer wheel for a vertical ring mill. The hammer wheel is arranged on a hammer wheel seat, wherein the hammer wheel seat is arranged on a hammer wheel shaft through a self-aligning bearing; a sealing device is arranged among the upper side and the lower side of the hammer wheel and the hammer wheel shaft. The hammer wheel seat is arranged on the hammer wheel shaft through the self-aligning bearing, and a deflection angle can be formed between the hammer wheel shaft and the outer ring of the self-aligning bearing; the self-adaptive control hammer wheel has the characteristics that firstly, materials entering the hammer wheel and a milling ring can be grinded and milled, so that the materials with smaller sizes are prevented from passing through the hammer wheel and the milling ring under the condition of no grinding as much as possible; secondly, during the grinding process, the upper end and the lower end of the hammer wheel and the milling ring can be used for grinding simultaneously, so that the abrasion at the upper end and the lower end is uniform; thirdly, a spherical surface sealing structure is adopted, and sealing can also be ensured when the hammer wheel deflects.

Description

Vertical type ring mill self adaptation governor weight wheel

Technical field

The present invention relates to a kind of vertical type ring mill hammer wheel.

Background technology

In existing ring rolling type flour mill technology, its grinding principle is the centrifugal motion of taking turns by hammer, the grinding pressure that hammer wheel is formed in rolling ring makes crushing material, hammer wheel face remains parallel with rolling ring face, to roll spacing identical rolling up and down region to hammer wheel face and rolling ring face into shape, rolling in process of material, first enter the upper area between hammer wheel and rolling ring, if now larger, harder material enters this region, will form the larger spacing that rolls in this region, material through pulverizing will be subject to compared with large material caused rolling of hammer wheel and rolling ring compared with rolling spacing greatly, like this, will cause, one, partial material is taken turns between rolling ring by hammer in the situation that not rolled, cause this partial material not pulverized, reduce mill efficiency, two, on forming between hammer wheel and rolling ring, roll region and often need to pulverize the material that some sizes are large, hardness is high, the condition of work that region is rolled in lower end is contrary, so just makes the hammer wheel and the rolling ring wearing and tearing that roll region accelerate, and the wearing and tearing of upper and lower two ends are inhomogeneous.

Summary of the invention

The object of this invention is to provide a kind of vertical type ring mill self adaptation governor weight wheel.

Technical scheme of the present invention is, a kind of vertical type ring mill self adaptation governor weight wheel, and hammer wheel is contained on hammer wheel seat, and hammer wheel seat is contained on hammer wheel shaft by self-aligning bearing, sealing device is housed in the both sides up and down of hammer wheel with hammering into shape between wheel shaft.

Described sealing device is, in the upper and lower both sides of hammer wheel, ball face sealing inner sleeve is housed, and on hammer wheel shaft, ball face sealing overcoat is housed, and ball face sealing inner sleeve is concentric with ball face sealing overcoat.

The present invention hammers wheel seat into shape and is contained in hammer wheel shaft by self-aligning bearing, hammer wheel shaft and self-aligning bearing outer ring can have drift angle, possesses following feature: one, enter hammer wheel and can both obtain rolling grinding with the material between rolling ring, reduce and avoid material that size is less taking turns and rolling ring by hammer without roll in the situation that; Two, in the process of grinding, the upper and lower side of hammer wheel and rolling ring can roll simultaneously, makes upper and lower side even wearing; Three, adopt ball face sealing structure, in the time of the deflection of hammer wheel, also can guarantee sealing.

Accompanying drawing explanation

Structural representation when Fig. 1 is normal condition of the present invention.

Top view when Fig. 2 is normal condition of the present invention.

Fig. 3 is that the present invention hammers the structural representation while taking turns deflection into shape.

Top view when Fig. 4 the present invention hammers wheel deflection into shape.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind of vertical type ring mill, swivel mount 3 is housed on main shaft 12, at the inwall of cylindrical shell 11, rolling ring 10 is housed, on swivel mount 3, by arm shaft 1, swing arm 2 is housed, vertical type ring mill self adaptation governor weight wheel is housed in swing arm 2, described vertical type ring mill self adaptation governor weight wheel, hammer wheel 5 is contained on hammer wheel seat 7, hammer wheel seat 7 is contained on hammer wheel shaft 4 by self-aligning bearing 6, the two ends of hammer wheel shaft 4 are contained in swing arm 2, take turns 5 both sides up and down and hammer into shape between wheel shaft 4 at hammer sealing device is housed, described sealing device is Shang Xia 5, both sides ball face sealing inner sleeve 9 to be housed at hammer wheel, on hammer wheel shaft 4, ball face sealing overcoat 8 is housed, ball face sealing inner sleeve 9 is concentric with ball face sealing overcoat 8.

There is end-play and end-play in self-aligning bearing.The play of bearing can allow the skew of bearing in certain limit like this, and after the deflection of hammer wheel, the less material falling through hammer wheel compare great gap, upper end just can be realized and roll grinding in lower end, but not directly falls without grinding.
