Description
Technical field
The utility model relates to powder milling device, particularly Vertical Mill shock absorption buffering mechanism.
Background technology
In process of production, usually successively through broken, storage, abrasive dust and packaging process, wherein abrasive dust operation is most important, and it is related to calcium carbonate powder granularity for calcium carbonate.When abrasive dust, usual employing Vertical Mill, and Vertical Mill is in milling process, vibration keeps away unavoidable, for ensure abrasive dust continue carry out, be often implemented in line feeding, therefore Vertical Mill is provided with feed pipe, the mounting means of traditional feed pipe is that feed pipe is directly connected with Vertical Mill, but the powder shop condition of our company is limited, and for saving production cost, the length of its feed pipe is shorter, therefore traditional connected mode is adopted, feed pipe self cannot balance out Vertical Mill and vibrate the extruding and stretching that bring, and our company is when designing, its feed pipe will pass wall, therefore when Vertical Mill vibratory output is excessive, feed pipe will pull wall, serious, wall will be pulled bad, thus bring unsafe factor.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of result is simple, the Vertical Mill shock absorption buffering mechanism of long service life and good damping effect.
The purpose of this utility model is achieved through the following technical solutions: Vertical Mill shock absorption buffering mechanism, it comprises Vertical Mill, bellows, feed pipe and tube connector, described bellows two ends are provided with a flange, and the two ends of bellows are connected with tube connector and feed pipe respectively by flange, described tube connector and the charging aperture of Vertical Mill are tightly connected, described bellows is also provided with two parallel up and down flange collars, ripple on bellows is between two flange collars, many Limit screws are connected with between two described flange collars, one end of Limit screw is provided with a locking nut, a pre-compressed spring is provided with between the other end of Limit screw and the lower surface of lower flange collar.
Described bellows is metal bellows.
Described Limit screw is four, and is evenly distributed on the same periphery of flange collar.
One elastic washer is installed between described locking nut and the upper surface of upper convex ring.
The utility model has the following advantages: Vertical Mill shock absorption buffering mechanism of the present utility model, feed pipe is provided with a bellows, the power that Vertical Mill vibrates described generation is fallen by the compression of bellows and stretching Absorbable rod, thus make the deflection of feed pipe very little, serve the effect of damping, buffering; And bellows is provided with Limit screw and pre-compressed spring, the deflection of bellows is diminished, thus extends the service life of bellows, and bellows is under the effect of the spring force of pre-compressed spring, bellows energy Rapid reset can also be made.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is I place cross-sectional schematic in Fig. 1;
In figure, 1-Vertical Mill, 2-bellows, 3-feed pipe, 4-tube connector, 5-flange, 6-flange collar, 7-Limit screw, 8-locking nut, 9-pre-compressed spring, 10-elastic washer, flange collar under 61-, 62-upper convex ring.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As depicted in figs. 1 and 2, Vertical Mill shock absorption buffering mechanism, it comprises Vertical Mill 1, bellows 2, feed pipe 3 and tube connector 4, described bellows 2 two ends are provided with a flange 5, and the two ends of bellows 2 are connected with tube connector 4 and feed pipe 3 respectively by flange 5, flange 5 makes the installation of bellows 2 very convenient, described tube connector 4 is tightly connected with the charging aperture of Vertical Mill 1, described bellows 2 is also provided with two parallel up and down flange collars 6, ripple on bellows 2 is between two flange collars 6, many Limit screws 7 are connected with between two described flange collars 6, one end of Limit screw 7 is provided with a locking nut 8, a pre-compressed spring 9 is provided with between the other end of Limit screw 7 and the lower surface of lower flange collar 61, in actual installation process, pre-compressed spring 9 when mounted, pre-compressed spring 9 is in compressive state, bellows 2 is made to have the trend of compression, when Vertical Mill 1 vibrates, when bellows 2 is subject to thrust and compresses, because bellows 2 has the trend of compression, therefore the compression of bellows 2 is comparatively mild, when Vertical Mill 1 vibrates, bellows 2 under tension and when stretching, the spring force that direction and pre-compressed spring 9 pairs of bellowss 2 of pulling force apply is contrary, thus make the pre-spring force of pre-compressed spring 9 can offset a part of pulling force, thus bellows 2 amount of tension is diminished, when the pulling force suffered by bellows 2 is larger, along with the stretching quantitative change of bellows 2 is large, the opposing spring force that pre-compressed spring 9 is given is also larger, thus reduce the deflection of bellows 2, and after pulling force disappears, bellows 2 will reset under the acting in conjunction of the spring force of therein stress and pre-compressed spring 9.
In the present embodiment, described bellows 2 is metal bellows, the elastic effect of metal material is excellent, after being extruded and stretching, easily resets, and metal material has good toughness, can bear and repeatedly compress and stretch, the inner surface of therefore its long service life, and metal bellows, the wearing and tearing of powder can be born for a long time, thus further ensure the service life of bellows 2.
In the present embodiment, described Limit screw 7 is four, and is evenly distributed on the same periphery of flange collar 6, thus makes the pulling force size suffered by Limit screw 7 identical, bellows is out of shape evenly, thus the damage avoiding bellows to cause because local deformation is excessive.
In the present embodiment, be provided with an elastic washer 10 between described locking nut 8 and the upper surface of upper convex ring 62, elastic washer 10 can absorb the power of a part of bellows compression or stretching, thus reduces the compression of bellows or the deflection of stretching.
