Abstract
The utility model provides a spiral tube sealing device of a ball mill belonging to a sealing device. The utility model is characterized in that in the ring clearance between the spiral tube and the feed-discharge pipe, a dead sealing ring is arranged on an outer surface of the feed-discharge pipe; a serrated ring groove is arranged on an outer ring surface and the right and left side surfaces of the dead sealing ring; the left surface of the dead sealing ring and the step surface of the spiral tube are pressed each other for sealing; the right surface of the dead sealing ring and the lateral surface of the flange are pressed each other for sealing; a flexible sealing ring with a pointed toothed outer layer is embedded in the serrated ring groove on the outer ring surface of the dead sealing ring; a pointed tooth and a internal column surface are pressed each other for sealing, which always plays a good role in sealing; in addition, between a right end surface of the spiral tube and the flange, a moving sealing ring is arranged on the right end surface of the spiral tube rotating along with the spiral tube and pressing on the lateral surface of the flange for sealing, which plays a role in sealing while a little powder of the material to mill is released out. The utility model has the advantages of the good sealing effect, the wear-resistance, the long service life, and the easy maintenance.
Description
Technical field
The utility model belongs to seal arrangement, especially relates to a kind of pebble mill seal arrangement.
Background technique
Pebble mill is widely used in the industries such as metallurgy, coal, electric power, building materials.During the pebble mill operation, volute can produce circular movement, parallel motion simultaneously and move up and down, connected feed and exhaust tube but is in relative static conditions, it is tight that volute and feed and exhaust tube are difficult to sealing, available technology adopting flange plate and immersion oil packing or graphite packing seal, shortcoming is the Sealing poor flexibility, easy to wear, working life is short, often produces the gap because of wearing and tearing, cause negative pressure instability in the pebble mill, influencing the efficient of pebble mill, is that the grinding charge material leaks befouling environment what is more, Sealing will often keep in repair or change, and the pebble mill operating rate is low.
Summary of the invention
The purpose of this utility model provides a kind of ball crusher spiral pipe sealing equipment, good springiness, wear-resisting, and long service life reduces cost, good seal performance, the efficient of raising pebble mill.
The purpose of this utility model is achieved like this: a kind of ball crusher spiral pipe sealing equipment, by volute, feed and exhaust tube and flange plate are formed, it is characterized in that the place, annular space between volute and feed and exhaust tube, the static seal circle is set on the outer surface of feed and exhaust tube, all make on the outer ring surface of this static seal circle and the left and right sides face and have the profile of tooth annular groove, be to be the tooth limit on the outer side of axial cross section of this static seal circle and the limit, the left and right sides, the left surface of this static seal circle compresses mutually and seals with the step surface of volute, the right flank of this static seal circle compresses mutually and seals with the side of flange plate, the setting-in skin is the elastic seal ring of pointed dentation in the profile of tooth annular groove of the outer ring surface of static seal circle, the pointed tooth of this elastic seal ring and the inner periphery of volute offset and seal, when frictional force is little between the two, elastic seal ring is in relative static conditions, when frictional force is excessive between the two, elastic seal ring rotates with volute, all the time play good seal action, in addition, between the right side and flange plate of volute, on the right side of volute, dynamic seal ring is installed, dynamic seal ring rotates together with volute and compresses mutually with the side of flange plate and seal, when the powder of a small amount of grinding charge material leaks, play seal action.
The ball crusher spiral pipe sealing equipment that the utility model proposed, rational in infrastructure, safe and reliable, good sealing effect, wear-resisting, the life-span is long, easy care has improved the working efficiency of pebble mill.
