Description
Affiliated technical field
The utility model belongs to the seal of rotary kiln technical field, and what relate generally to is the rotary kiln bidirectional sealing device.
Technical background
Rotary kiln is the high-temperature sintering equipment of the products such as grog of industry extensive uses such as building materials, coloured, metallurgy and chemical industry.
It is inevitable when being connected with stationary object to have the gap that exists between the cylinder of rotary kiln of constant slope, high temperature rotation and static kiln hood and the kiln tail and be moving object.When this clearance seal was bad, cold air will bleed in the kiln by the gap under the draft of powerful exhaust blower, can reduce the temperature and the firing temperature of burning so first, influenced the calcining of heat exchanger effectiveness and goods, increased energy consumption; Second cause kiln tail exhaust smoke level to increase, strengthened the load of exhaust blower, increased power consumption.Because rotary kiln is factory's " heart " equipment, thus the sealing quality of rotary kiln end and kiln tail, the thermal regulation when being directly connected to rotary kiln running in the kiln, the stability of the output of grog, quality, operation simultaneously, has also reduced the running rate of rotary kiln.Therefore, sealing is a vitals of rotary kiln, also is one of criterion of rotary system design level.
Early stage be sealed with labyrinth sealing, it is to adopt a moving labyrinth ring and quiet labyrinth ring formation that is nested together, and does not have contact-making surface.Come in contact at the volley for fear of dynamic and static sealing ring, that considers cylindrical shell expands with heat and contract with cold, goes here and there factors such as moving, bending, circular runout, no matter labyrinth sealing all can not be too little at radial and axial preset clearance, therefore, the labyrinth sealing disadvantage is that sealing effectiveness is undesirable, only is applicable to occasion that pressure is little or is used in combination with other sealing.
The radial friction sealing of invention at the end of the nineties in last century is to use more sealing device at present, this sealing is mainly assembled around kiln cylinder body by all polylith graphite blocks (movable friction plate), the size of graphite block and quantity are decided according to kiln diameter and the graphite source of goods and specification, and general section is a rectangle.Graphite block is pressed to cylindrical shell by the radial pressure (pressure at right angle) that top spring produces, and both are kept in touch, and graphite block both had been close to the cylindrical shell cylindrical, can make radial floating with the beat of kiln again, can also allow the axial float of cylindrical shell.Because the degree of tension of spring is adjustable, thereby the pressure of sealing contact surface needn't be excessive, keeps in touch to get final product.But the problem that exists during this sealing is used is:
1, the bottom graphite block is easily blocked by the grog particle, can not reset, and graphite block and cylindrical shell are disengaged, and forms the slit of leaking out;
2, the metal flange (both parts of kiln hood) that directly pasting in the axial direction of graphite block (both movable friction plates) rather than be the static friction sheet, therefore, often the bad kiln that need stop the long period of metal flange (both parts of kiln hood) wearing and tearing is repaired or upgraded;
3, graphite block (both movable friction plates) can only be pressed to cylindrical shell by the radial pressure (pressure at right angle) that top spring produces, and makes graphite block radially paste cylindrical shell, radial seal that can only be relative.Scurried downslide (both endwisely slipping) in the meeting because rotary kiln expands with heat and contract with cold when producing, gravity glides, produce influencing of factor such as adjustment.Therefore, graphite block still can not paste static friction sheet (flange) in the axial direction, produces the gap between the dynamic and static friction plate and cause, and causes axially and leaks out.Thereby the only enough limited control of radial friction sealing leaks out, and is not to control fully, and sealing effectiveness is general, and the scope of application also has been subjected to certain restriction.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of rotary kiln bidirectional sealing device.Solve the problem of leaking out of rotary kiln end and kiln tail.
The utility model realizes that the technical scheme that above-mentioned purpose is taked is: it mainly is made up of movable friction plate, static friction sheet, slideway cylindrical shell, axle spring, guide pillar, slip pipe nipple and radial spring, movable friction plate is made up of a plurality of identical rectangular blocks, be positioned on the slideway cylindrical shell of rotary kiln body, locate by the spring radial compaction; The static friction sheet is a cirque structure, be arranged on the slideway cylindrical shell of rotary kiln body, between movable friction plate and kiln hood, the slideway cylindrical shell is provided with the retaining platform of annular, be distributed with a plurality of spring bases on the circumference of this retaining platform, be equipped with axle spring and guide pillar in each spring base, the front end of guide pillar compresses the slip pipe nipple, by the slip pipe nipple movable friction plate and static friction sheet are axially fitted tightly, between movable friction plate and static friction sheet and slip pipe nipple, formed the radial and axial two way seal that all is subjected to spring compression thus.
The utility model is by endwisely slipping at slip pipe nipple that is provided with on the kiln body and the slideway between the slideway cylindrical shell, the axial stretching amount when relying on a spring to absorb the cylindrical shell operation.Simultaneously, compress dynamic friction piece and static friction sheet and form axial seal; Radial seal is to utilize radially relatively rotating between movable friction plate and the spring to realize.Formed axial and two way seal radially; This seal of rotary kiln device has good sealing effect, and is simple in structure, reliable, easy for installation, reduced maintenance workload significantly, and the output and the quality stable, grog of the thermal regulation of rotary kiln played crucial effects.Have the coal consumption of reduction, improve yield and quality, improve comprehensive functions such as rotary kiln running rate and economic benefit.
