Abstract
A ball mill sealing apparatus pertains to a cylindrical grinding mill, in particular to a ball mill fitting, which comprises a static sealing ring and a movable sealing ring that is matched with the static sealing ring. The utility model is characterized in that: the static sealing ring is felt on the pressing plate that is movably connected on the flange, while the flange is fixed on the feeding pipe and the discharging pipe and the movable sealing ring is fixed in the spiral pipe. When the sealing ring is abraded and the spiral pipe parallel moves, the pressing plate moves inwards so as to automatically compensate the gap resulting from the abrasion of sealing rings and maintain the tightness. The utility model has the advantages as follows: good in elasticity, wearable, good in sealing capability, long in service life, the utility model can reduce repair and maintain a stable negative pressure in the ball mill and prevent the grinded material from discharging out and is favorable to increase the working efficiency of the ball mill.
Description
Technical field
The utility model relates to the cylindrical shape grater, relates in particular to the ball mill part.
Background technology
Ball mill is widely used in the industries such as metallurgy, coal, building materials.During the ball mill operation, helix tube can produce circumferential movement, parallel motion simultaneously and move up and down, and connected charging and discharging pipe but is in relative static conditions, and it is tight that helix tube and charging and discharging pipe are difficult to sealing.Available technology adopting flange and immersion oil packing or graphite packing seal.Shortcoming is the seal poor flexibility, and is easy to wear, and service life is short, because of wearing and tearing produce the gap, causes negative pressure instability in the ball mill, influences the efficient of ball mill, and the grinding charge material leaks what is more, contaminated environment; Seal will often keep in repair or change, and the ball mill operating rate reduces.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model provides the Sealing means for ball milling machine of a kind of good springiness, wear-resisting, long service life, good seal performance.
Sealing means for ball milling machine, comprise static seal circle and the dynamic seal ring that cooperates with it, be characterized in that the static seal circle is bonded on the pressing plate, pressing plate is movably connected on the flange, flange is fixed on the charging and discharging pipe, dynamic seal ring is fixed in the helix tube during use, and static seal circle roof pressure dynamic seal ring is sealed.
The utility model further improves, and flange is to be formed by connecting by 2 Ha Fuquan, is convenient to processing and installs, and evenly establishes the through hole of wearing screw rod and the installing hole that is connected with the charging and discharging pipe on it; Pressing plate is made up of unconnected ring plate, and ring plate is provided with screw rod, and is corresponding with the through hole on the flange; Screw rod on the pressing plate wears sleeve pipe, spring and nut, is movably connected on the flange by through hole.Adjusting nut can adjust the gap between static seal circle and the dynamic seal ring and compress degree.When ring wear and helix tube parallel motion, pressing plate moves inward the gap that can the automatic compensation sealing circle produces because of wearing and tearing, thereby keeps its sealing.
Compared with prior art, its advantage is: the sealing device good springiness, and wear-resisting, the gap that can produce with the wear automatic-compensation of sealing pair keeps high-seal; The ball mill internal pressure is stable, has stopped material and has leaked, and has improved ball mill efficiency, has reduced environmental pollution; Prolong service life, reduced maintenance and changed, helped improving the operating rate of ball mill.
Description of drawings
The utility model is described in further detail in conjunction with the accompanying drawings.
Fig. 1 Sealing means for ball milling machine structural representation.
Fig. 2 Sealing means for ball milling machine structure side view.
The specific embodiment
By accompanying drawing as can be seen, Sealing means for ball milling machine is made up of flange 1, pressing plate 2, static seal circle 3 and dynamic seal ring 4, and on the static seal circle 3 bonding pressing plates 2, pressing plate 2 is movably connected on the flange 1, and flange 1 is fixed on the charging and discharging pipe 6.Dynamic seal ring 4 is fixed in the helix tube 5, matches, compresses with static seal circle 3 on being bonded in pressing plate 2.
By accompanying drawing as can be seen, flange 1 is formed by connecting by 2 Ha Fuquan, and through hole and installing hole evenly are set on the Ha Fuquan; Pressing plate 2 is made up of the ring plate that is not connected, and it is corresponding with the through hole of flange 1 that ring plate is provided with screw rod 9; Screw rod 9 on the pressing plate 2 puts sleeve pipe 7, spring 8, nut 10, by through hole flange 1 and pressing plate 2 is movably connected.Adjust nut 10, can adjust spring 8, that is adjust the gap of static seal circle 3 and dynamic seal ring 4 and compress degree.
