Description
Technical field
The present invention relates to a kind of sealing device, the bucket wheel on especially a kind of ball mill and the sealing device at charging aperture place belong to the sealing device technical field on the ball mill.
Background technology
In industries such as cement, silicate product and New Building Materials, ball mill is that material is pulverized the key equipment of pulverizing again afterwards, treats that comminuting matter enters into ball mill from feed arrangement, is pulverized the back and discharges from drawing mechanism.In order to guarantee that material can be fed in the ball mill equably; The feed arrangement of General Spherical grinding machine is all connected to form by bucket wheel and charging quarrel; Material is admitted to the bucket wheel from the charging quarrel, through the pivoting leaf in the bucket wheel material is sent in the ball mill equably.In order to improve the material grinding effect; Generally adopt felt sealing device (as shown in Figure 1) at bucket wheel and charging quarrel place; Charging quarrel 20 is inserted in the bucket wheel 10, and felt 30 is fixed on the bucket wheel 10, and is positioned at the junction of charging quarrel 20 and bucket wheel 10; Felt 30 is pressed on the junction of bucket wheel 10 and charging quarrel 20 through the clamp 40 that is positioned at its outside, thereby reaches the effect of sealing.Because felt 30 is mounted on bucket wheel 10 bodies and rotates with grinding machine, felt 30 wearing and tearing are very fast, and change frequent.Get into the material in the bucket wheel 10, usually be stuck in the gap between bucket wheel 10 and the charging quarrel 20, charging quarrel 20 is caused extruding, make it to produce skew, friction takes place with bucket wheel 10 and damages in charging quarrel 20.The skew of charging quarrel 20; Make felt 30 wearing and tearing aggravations; Sealing is destroyed; Cause the generation of leakage, air leakage phenomena, and the replacing of charging quarrel 20 has relatively high expectations with the concentricity and the fit clearance of bucket wheel 10 inlets to the circularity of charging quarrel 20, charging quarrel 20, cause the maintenance of equipment to change chronic.
Summary of the invention
Technical problem to above-mentioned existence; The objective of the invention is: proposed a kind of simple in structure, cost is low; The phenomenon that can stop to leak, leak out takes place, and can prolong the service life of encapsulant, improves the ball mill bucket wheel and the charging aperture sealing device of operation rate.
Technical solution of the present invention is achieved in that a kind of ball mill bucket wheel and feed hopper mouth sealing device, comprises bucket wheel, charging quarrel and airtight and watertight padding; One side of said bucket wheel is provided with a boss, and boss in have a charging hole that communicates with bucket wheel inside in the heart; Said charging quarrel is inserted in the charging hole; Said airtight and watertight padding is positioned at the boss outside; Also comprise baffle plate, snap ring, fixed head and adjusting bolt; Said airtight and watertight padding extends to the junction of the wheel face and the boss of bucket wheel, and boss is wrapped in the airtight and watertight padding; Said airtight and watertight padding is fixed in the charging quarrel through being positioned at the snap ring in its outside; The plane parallel of said baffle plate and boss, and be pressed in the airtight and watertight padding; Also be provided with the adjusting bolt on the said baffle plate; Said fixed head is fixed on the ball mill; Said baffle plate is connected through regulating bolt with fixed head.
Preferably, the external diameter of said charging quarrel is than the little 25～30mm in charging aperture of bucket wheel.
Preferably, said airtight and watertight padding is the oil immersion packing.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
A kind of ball mill bucket wheel of the present invention and charging aperture sealing device; Owing to adopted the airtight and watertight padding of bucket wheel boss in being wrapped in, bolt is regulated the pressing of airtight and watertight padding and bucket wheel and charging quarrel through regulating, seal degree, and through snap ring airtight and watertight padding is fixed in the charging quarrel; When effectively avoiding the airtight and watertight padding wearing and tearing; Also guaranteed the sealing of its junction, the phenomenon of having stopped to leak material, leak out takes place, and charging aperture is not easy to wear; Change encapsulant make things convenient for, save time, laborsaving, easy to operate, and prolonged service life of encapsulant.The present invention program's ball mill bucket wheel and charging aperture sealing device, it is simple in structure, and cost is lower; Gap between bucket wheel and the charging aperture is increased; Avoid the phenomenon that material is stuck in the gap in the bucket wheel to take place effectively, reduced the wearing and tearing of bucket wheel and charging quarrel, prolonged the service life of equipment; Not only improved the running rate of equipment, production efficiency also is greatly improved.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is ball mill bucket wheel of the prior art and inlet sealing device structural representation;
Accompanying drawing 2 is ball mill bucket wheel of the present invention and inlet sealing device structural representation;
Wherein: 1, bucket wheel; 2, snap ring; 3, fixed head; 4, charging quarrel; 5, regulate bolt; 6, baffle plate; 7, airtight and watertight padding; 8, boss; 9, charging hole.
The specific embodiment
