Abstract
The utility model discloses a feeding sealing device of a wet type ball mill, belonging to the technical field of ball mills and comprising a feeding chute of the mill, a sealing ring arranged on the feeding chute, a sealing gland, a sealing ring, a feeding pipe flange and a connecting bolt. In the utility model, the sealing ring is arranged on the feeding chute, so that the traditional radial sealing is developed into the sealing in axial direction and on an inclined plane; and the sealing ring has self-compensation function for wear, good sealing effect and long service life.
Description
Technical field:
The utility model relates to a kind of sealing device, relates to a kind of sealing device that is used for wet ball mill charging place specifically.
Background technology:
Now wet ball-milling machine inlet capable spillage is present ubiquitous problem, and spillage is except influencing environment and maintenance, even leaks to main bearing box pollution lubricating oil and bearing shell, and ball mill can't be moved, and causes serious consequence.
Have based on this, make the utility model.
The utility model content:
At the problem that prior art exists, the purpose of the utility model patent provides a kind of safe and reliable wet ball mill entrance lock.
The technical scheme that the utility model is taked for achieving the above object is: a kind of wet ball mill entrance lock, comprise grinding machine charging elephant trunk, it is characterized in that: be set with sealing ring, sealing ring on the charging elephant trunk, sealing gland is fixed in sealing ring, sealing ring on the feed pipe flange.
Preferably, seal ring set is loaded on the charging elephant trunk, and sealing ring has the portion of curving inwardly, and the contact-making surface of sealing ring and sealing ring is set to the inclined-plane, and the bend of sealing ring matches with the inclined-plane of sealing ring, and sealing ring contacts with the charging elephant trunk along the bend extension.Preferably, sealing gland is fixed sealing ring and sealing ring respectively by connecting bolt.
Main feature of the present utility model is: sealing ring has wear-self-compensation effect, good sealing effect, long service life.The sealing ring that is provided with on the charging elephant trunk assists sealing ring to curve inwardly, and behind the ring wear, internal diameter of the seal ring increases simultaneously, and then sealing ring contacts with sealing ring, prolongs the sealing ring life cycle.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. charging elephant trunk, 2. sealing ring, 3. sealing ring gland, 4. sealing ring, 5. feed pipe flange, 6. connecting bolt.
The specific embodiment:
As shown in the figure, a kind of wet ball mill entrance lock, comprise grinding machine charging elephant trunk 1, be arranged on sealing ring 2, sealing gland 3, sealing ring 4, feed pipe flange 5 and connecting bolt 6 on the charging elephant trunk, wherein sealing ring 2 is set on the charging elephant trunk 1, sealing gland 3, sealing ring 4 are set in sealing ring 2 outsides, and are fixed on the feed pipe flange 5 by connecting bolt 6.
In the utility model, sealing ring 4 has inwardly (axially) bend, sealing ring 2 is set in the exit of charging elephant trunk 1, sealing ring 4 is pressed in sealing ring 2 on the charging elephant trunk 1 on the one hand, and preferably, sealing ring 2 is set to the inclined-plane with the contact-making surface of sealing ring 4, the bend of sealing ring 4 matches with the inclined-plane of sealing ring 2, contacting with charging elephant trunk 1 along the bend elongated end of sealing ring 4, sealing gland 3 is fixed sealing ring 2 and sealing ring 4 respectively, thereby forms a compensate for wear device.When the sealing ring small amount of wear, the automatic resilience of the bend of sealing ring 4 meeting, radius of curvature increases, and guarantees that sealing ring 4 can also contact with charging elephant trunk 1, and further after the wearing and tearing, internal diameter of the seal ring contacts with sealing ring, also can guarantee to seal.So the utlity model has the wear-compensating effect, prolonged the service life of sealing ring, and simple structure compactness, cost low, be easy to realize.
Claims (3)
1. a wet ball mill entrance lock comprises grinding machine charging elephant trunk, it is characterized in that: be set with sealing ring, sealing ring on the charging elephant trunk, sealing gland is fixed in sealing ring, sealing ring on the feed pipe flange.
2. a kind of wet ball mill entrance lock according to claim 1, it is characterized in that: seal ring set is loaded on the charging elephant trunk, sealing ring has the portion of curving inwardly, the contact-making surface of sealing ring and sealing ring is set to the inclined-plane, the bend of sealing ring matches with the inclined-plane of sealing ring, and sealing ring contacts with the charging elephant trunk along the bend extension.
3. a kind of wet ball mill entrance lock according to claim 1 is characterized in that: sealing gland is fixed sealing ring and sealing ring respectively by connecting bolt.
