Abstract
The utility model discloses a magnetic sealing ring for a mine ball mill, belongs to the technical field of mine mechanical equipment and is used for sealing a magnetic ore-pulp transfer joint of the mine ball mill. The technical scheme is as follows: the magnetic sealing ring is a sealing ring made of permanent magnet medium, and is flange-shaped; the upper part of the sealing ring is provided with a round disc; fixed screw holes are uniformly distributed at the periphery of the round disc; the lower part of the sealing ring is provided with a sleeve; the diameter of a central through hole of the sleeve is matched with that of a feeding pipe; and a gap is left between the hole wall of the central through hole of the sleeve of the sealing ring and the outer diameter of the feeding pipe. The magnetic sealing ring absorbs magnetic minerals in overflowing ore pulp by utilizing a ring-shaped permanent magnet of the sleeve of the sealing ring so as to compensate a gap between a sealing device and the feeding pipe, form a magnetic liquid O-shaped sealing ring and achieve the sealing effect. The magnetic sealing ring has the advantages that the effect is obvious in use, the wear of the feeding pipe can be reduced, the service life of the feeding pipe is prolonged, the problem of ore throwing of an ore feeding end is effectively solved, the disassembly is more convenient, and the original sealing device can be effectively replaced.
Description
Technical field
The utility model relates to the seal arrangement at pebble mill magnetic ore pulp forwarding interface place, a kind of mine, belongs to the mine mechanism technical field.
Background technique
At present; Mine ore dressing factory pebble mill is the plastic shaping packing seal to the motive sealing form of ore deposit end feeding pipe and pan feeding lining, and this seal arrangement sealing effect is not good, and on-the-spot ore pulp is revealed serious; The wearing and tearing of feeding pipe and pan feeding lining have been increased; Shorten the life time of feeding pipe, also caused to the ore deposit end and get rid of the ore deposit problem, influenced carrying out smoothly of producing.The working life of this seal arrangement is short simultaneously, replacing is frequent, and shutting down to change has also influenced the manufacturing mechanism operating rate.Therefore, it is very necessary existing mine ore dressing factory pebble mill being improved to the dynamic seal apparatus of ore deposit end feeding pipe and pan feeding lining.
The model utility content
The utility model technical problem to be solved provides a kind of good sealing effect, not fragile, the magnetic gasket that is used for the mine pebble mill being convenient to change.
The technological scheme that solves the problems of the technologies described above is:
A kind of magnetic gasket that is used for the mine pebble mill, it is to be the seal ring of material with the permanent magnetism magnetic medium, seal ring is a flange-like; Disk is arranged at the top of seal ring; Disk circumference is evenly equipped with fixing threaded hole, and the bottom of seal ring is a sleeve, and the diameter and the feeding pipe of the center through hole of sleeve are complementary.
The above-mentioned magnetic gasket that is used for the mine pebble mill, gapped between the hole wall of the center through hole of said seal ring sleeve and the feeding pipe external diameter.
The utility model is applicable to the sealing of mine pebble mill magnetic ore pulp forwarding interface; Can utilize the annular permanent-magnet body of seal ring sleeve to draw magnetic mineral in the excessive ore pulp; In order to the gap between compensation sealing device and the feeding pipe; Form magnetic liquid " zero " type seal ring, to reach sealing effect.The utility model in use effect is obvious, can alleviate feeding pipe wearing and tearing, prolong feeding pipe working life, solved to the ore deposit end effectively and got rid of the ore deposit problem, and dismounting is comparatively convenient, can substitute original seal arrangement effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Mark is following among the figure: seal ring 1, feeding pipe 2, pan feeding lining 3, fixing bolt 4, magnetic mineral 5.
Embodiment
The utility model be the magnetic intensity made from a kind of permanent magnetism magnetic medium moderate, keep the seal ring 1 of reasonable clearances to replace original seal arrangement with feeding pipe 2.
Show among the figure that seal ring 1 is a flange-like, disk is arranged at the top of seal ring 1; Disk circumference is evenly equipped with fixing threaded hole; The bottom of seal ring 1 is a sleeve, and the diameter of the center through hole of sleeve and feeding pipe 2 are complementary, and is gapped between the hole wall of the center through hole of seal ring 1 sleeve and feeding pipe 2 external diameters.
Show among the figure that process groove on the pan feeding lining 3 with material entrance, the magnetic seal ring 1 moderate the magnetic intensity of making is bumped into bush end face; With fixing bolt 4 the top disk of seal ring 1 is fixed; Magnetic seal ring 1 needs to keep reasonable clearance with feeding pipe 2, utilizes the annular permanent-magnet body of seal ring 1 sleeve to draw magnetic mineral 5 in the excessive ore pulp, in order to the gap between compensation sealing device and the feeding pipe; Form magnetic liquid " zero " type seal ring, to reach sealing effect.
