Abstract

The invention discloses a kind of vertical type ring mill Automatic adjusument hammer wheel, hammer wheel is contained on hammer wheel seat, and hammer wheel seat is contained on hammer wheel shaft by self-aligning bearing, equipped with sealing device between the both sides up and down of hammer wheel and hammer wheel shaft。The present invention hammers wheel seat into shape and is contained in hammer wheel shaft by self-aligning bearing, hammer wheel shaft can have drift angle with self-aligning bearing outer ring, possesses following feature: one, the material entered between hammer wheel and rolling ring can both obtain rolling grinding, reduces and avoids smaller material when without passing through hammer wheel and rolling ring when rolling；Two, in the process of grinding, the upper and lower side of hammer wheel and rolling ring can roll simultaneously so that upper and lower side even wearing；Three, adopt ball face sealing structure, when hammer wheel deflection, also can guarantee that sealing。

Description

Vertical type ring mill Automatic adjusument hammer 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 by hammering wheel into shape, the grinding pressure that hammer wheel is formed in rolling ring is made to make crushing material, hammer wheel face remains parallel with rolling ring face, namely rolling region up and down, to roll spacing identical in hammer wheel face and rolling ring face, in the roller compaction process of material, initially enter the upper area between hammer wheel and rolling ring, if it is now bigger, harder material enters this region, then will be formed in this region and bigger roll spacing, size-reduced material will be rolled more greatly spacing and rolling by hammer wheel and rolling ring by what bigger material caused, so, will result in, one, partial material is taken turns when not rolling between rolling ring by hammer, this partial material is caused not pulverized, reduce mill efficiency；Two, roll region on being formed between hammer wheel and rolling ring and it is frequently necessary to pulverize the material that some sizes are big, hardness is high, the working condition that region is rolled in lower end is then contrary, thus makes the hammer rolling region take turns and rolling ring abrasion is accelerated, and the abrasion of upper and lower two ends is uneven。

Summary of the invention

It is an object of the invention to provide a kind of vertical type ring mill Automatic adjusument hammer wheel。

The technical scheme is that, a kind of vertical type ring mill Automatic adjusument hammer wheel, hammer wheel is contained on hammer wheel seat, and hammer wheel seat is contained on hammer wheel shaft by self-aligning bearing, equipped with sealing device between the both sides up and down of hammer wheel and hammer wheel shaft。

Described sealing device is to take turns upper and lower both sides equipped with ball face sealing inner sleeve at hammer, and equipped with ball face sealing overcoat on hammer wheel shaft, 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 can have drift angle with self-aligning bearing outer ring, possesses following feature: one, the material entered between hammer wheel and rolling ring can both obtain rolling grinding, reduces and avoids smaller material when without passing through hammer wheel and rolling ring when rolling；Two, in the process of grinding, the upper and lower side of hammer wheel and rolling ring can roll simultaneously so that upper and lower side even wearing；Three, adopt ball face sealing structure, when hammer wheel deflection, also can guarantee that sealing。

Detailed description of the invention

Such as Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind of vertical type ring mill, equipped with swivel mount 3 on main shaft 12, at the inwall of cylinder 11 equipped with rolling ring 10, by arm shaft 1 equipped with swing arm 2 on swivel mount 3, equipped with vertical type ring mill Automatic adjusument hammer wheel in swing arm 2, described vertical type ring mill Automatic adjusument hammer 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, equipped with sealing device between the both sides up and down of hammer wheel 5 and hammer wheel shaft 4, described sealing device is equipped with ball face sealing inner sleeve 9 in hammer wheel about 5 both sides, equipped with ball face sealing overcoat 8 on hammer wheel shaft 4, 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 such bearing can allow bearing in a range of skew, and after hammer wheel deflection, the less material fallen through hammer wheel upper end larger gap just can realize in lower end rolling grinding, but not directly falls without grinding。
