Abstract
The invention discloses a kiln tail sealing device which comprises a rotary kiln. A feeding bracket is arranged on the rotary kiln; the tail part of the rotary kiln is provided with a smoke chamber; a cold air sleeve is arranged between the smoke chamber and the rotary kiln; a kiln tail flake seal is arranged between the cold air sleeve and the smoke chamber; a lubricating device is arranged on the smoke chamber wall at the upper part of the kiln tail flake seal; the lubricating device comprises a lubricating oil barrel and an oil spraying pipe which are fixed on a platform on the side wall of the smoke chamber; the oil spraying pipe is communicated with the lubricating oil barrel by a pipeline; the oil spraying pipe is fixed right above the kiln tail flake seal; and the oil spraying pipe which is over against the kiln tail flake seal is provided with a plurality of oil spraying holes. Tests show that since the lubricating device is additionally arranged for over 1 year, the cold air sleeve and a flake are not worn out; the lubricating device is simply designed and uses waste oil eliminated by other equipment; and the scheme has the advantages of low investment and easiness in maintenance.
Description
Technical field
The present invention relates to the new type nonaqueous cement production line field, relate in particular to rotary kiln flap seal lubrication.
Background technology
The dry method production line seal of rotary kiln is the requisite part of system, and it is directly connected to production line energy consumption height.At present, the sealing of using in the industry mostly is: graphite block sealing, flap sealing, air-cylinder type sealing, its various sealing pluses and minuses differ.
My rotary kiln designing institute of company is sealed into the graphite block sealing for its kiln tail that designs, and because its fault rate is high, and can not change online, does not want to stop kiln if this just causes, just can only let alone to leak out, system energy consumption increases, and increases production cost.Company technique personnel designed, designed and installation, the sealing of kiln tail has been replaced with the fish scale lamellar seal in May, 2009, the 16Mn steel plate (thickness is 8mm) that cold wind shroud adopts, what flap used is 1Cr18Ni9Ti steel plate (thickness is 3mm).Because the cold wind shroud material is softer, cause six months cold wind shroud just by mill thoroughly, cold wind shroud also is replaced by the thick 1Cr18Ni9Ti steel plate of 8mm subsequently, incident is that flap just all wore and tore in the most multiplex 2 months.
Summary of the invention
The object of the present invention is to provide a kind of kiln tail sealing device, can prolong the rotary kiln flap and seal service life.
For achieving the above object, the present invention is by the following technical solutions:
A kind of kiln tail sealing device, comprise rotary kiln, be provided with the feeding carriage at rotary kiln, afterbody at rotary kiln is provided with smoke-box, between smoke-box and rotary kiln, be provided with cold wind shroud, be provided with the sealing of kiln tail flap between cold wind shroud and the smoke-box, smoke-box wall on kiln tail flap sealing top is provided with lubricating arrangement, lubricating arrangement comprises the lubricating oil cylinder that is fixed on the smoke-box sidewall platform and drenches oil pipe, drenching oil pipe is communicated with the lubricating oil cylinder by pipeline, and drench oil pipe be fixed on the sealing of kiln tail flap directly over, one drench oil pipe and be provided with several and drench oilhole what face the sealing of kiln tail flap.
Above-mentioned kiln tail sealing device drenching the oil pipe one side opposite with the sealing of kiln tail flap by a threeway connection petroleum pipeline, drenches oil pipe and is communicated with the lubricating oil cylinder by petroleum pipeline.
Above-mentioned kiln tail sealing device is provided with ball valve at petroleum pipeline.
Above-mentioned kiln tail sealing device drenches oil pipe apart from kiln tail flap sealing 20mm.
Above-mentioned kiln tail sealing device, described pouring tubing diameter is 25, and length is 200mm, and two sealing, and it is 8 circular pouring oilholes of 4 that relative one side with the sealing of kiln tail flap has diameter.
Lubricating method among the present invention is directly oil to be drenched on cold wind shroud by drenching oil pipe, to form oil film, plays the effect that guarantees cold wind shroud and flap.The lubricating oil cylinder is fixed on the platform of smoke-box sidewall, and petroleum pipeline is all processed according to on-the-spot actual size is on-the-spot with the pouring oil pipe, and drenching oil pipe is to make with coating steel pipe, directly is fixed on oily.
Drenching oil in the lubricating arrangement among the present invention is automatic oil-spraying, drenches oil mass and adjusts the pouring oil mass by regulating the ball valve aperture.
The invention has the advantages that: 1, through test, cold wind shroud and flap are not worn 2, this lubricating arrangement simplicity of design mainly with coming to install lubricating arrangement 1 year additional, usefulness be that other equipment waste oil 3, this formula investing of eliminating are little, easy care.
