Description

Dust humidifier and dust air-humidification method

The present invention relates to a kind of dust damping device, and relate to the method that this device of use carries out the dust humidification, particularly relate to a kind of dust damping device that adds the strong dust of wet adhesion.

The dust of dry dust removal systematic collection when outward transport discharging for avoiding reentrainment of dust need add wet process.Existing various dust humidifier, as the drum-type humidifier, the spiral humidifier of single shaft, twin axle humidifier etc., wherein any, in the dust humidification, form annular adhesion layer (hereinafter to be referred as adhesion layer) in the gap of capital between cylinder inner surface and paddle top, wearing and tearing along with the paddle top, this adhesion layer can be more and more thicker, and preceding DRP DE2615506 discloses a kind of mixing arrangement, because its rotating speed height, the also corresponding increase of centrifugal force easilier forms solid adhesion layer at cylinder inner surface.U.S. Pat 4483625 disclosed a kind of mixing arrangements, because its rotating speed is restricted, be difficult to add the composition of hydrophily difference in the wet dust, and adhering composition in the dust, except cylinder inner surface, also forming adhesion layer at the outer surface of shaft and paddle.Adhesion layer not only makes the humidifier performance reduce, and humidification efficiency descends, and energy consumption increases, humidifying component wearing and tearing aggravation, and make motor overload when serious, see commentaries on classics, and especially when adding the strong dust of wet adhesion, this problem is more outstanding.In order to address this problem, the method for taking is usually for example used ceramic material scraper plate or puddler, can only reduce the wearing and tearing of humidifying component; Though the water flushing is feasible, but usually muddy water flows over, form secondary pollution, if following flow device is belt conveyer or other transporter, just do not allow the water flushing, as for adopting method for oscillating to remove adhesion layer, be commonly referred to be impossiblely, for example in the design of jigging conveyer, just think " jigging conveyer generally is not suitable for toughness or granularity is carried less than the 0.06mm powder " (the 160th page of publishing house of construction material Machine Design Wuhan Polytechnical Univ front page in July nineteen ninety).Have close-burning dust in humidifier behind the humidification viscosity stronger, wet viscous material is under the vibration of vibrator, the adhesion layer that is positioned at the cylindrical shell upper inside wall can be shaken, but adhesion layer in the cylindrical shell bottom interior wall, may shake more real and more real, moisture content also can increase the bur humidity near the cylindrical shell bottom interior wall along with vibration moves down.Therefore, also do not adopt vibrator to solve the dust humidifier of dust bonding so far.

The objective of the invention is to provide a kind of under the prerequisite that satisfies the dust humidification requirement, can reduce amount of water reduces by dust damping device and the dust air-humidification method of humidification stirring thing adhesiveness to prevent effectively or to reduce adhesion layer and make adhesion layer be easy to remove, even being stirred thing by humidification is the strong dust of adhesiveness, also can prevent owing to adhere to the stirring efficiency decline that is caused, and can reduce or remove the adhesion layer of cylinder inboard wall effectively, can also accelerate to be stirred thing and discharge from discharging opening by humidification.

The described dust damping device of purpose of the present invention is to realize with following technical scheme: comprise transmission mechanism, bearing block, level or comprise cylindrical shell to barrel and mixing drum, be bearing in shaft on the bearing block, be positioned to the charging aperture on the barrel, the injection apparatus on the cylindrical shell to what discharging opening tilted to install, the frame of supporting transmissioning mechanism and cylindrical shell, be positioned at the dust humidifier of the discharging opening of the relative end in cylindrical shell below, it is characterized in that being equipped with anti-bonding device with charging aperture.

The described dust air-humidification method of purpose of the present invention is to realize with following technical scheme: serve as to reduce adhesiveness that amount of water reduces material behind the humidification preventing effectively or to reduce adhesion layer and make adhesion layer be easy to remove, make near cylinder inner surface and/or scrape or the moisture content that falls of shaking is high is stirred thing by humidification and comprise being mixed by humidification stirring thing of flying dust near the cylindrical shell center from the adhesion layer of cylinder inner surface.Can also scrape or the moisture content that shakes is high by humidification that back time-delay the stopping feed that stops to feed water or stop to feed water when stirring thing makes it and mixes from the dry dust that charging aperture enters.

The prone puddler in installing end can significantly improve the performance of rotary beating type dust humidifier on the shaft.The high speed rotating stirring rod has revolves the effect of loosing that impacts, and the material of being broken up runs foul of each other and mixes.What the humidity of the close cylinder inboard wall of the prone part handle in puddler end was bigger is hit to the cylindrical shell center by humidification stirring thing, and the straight line portion of puddler hits to cylinder inboard wall being stirred thing by humidification, both strengthened immixture, can reduce adhesion again cylinder inboard wall.Puddler should evenly distribute in whole inner barrel, as for the arrangement mode of puddler on shaft can be arbitrarily, whether hit the characteristic did not influence for revolving of puddler, but helical arrangement is a kind of puddler evenly distributed a kind of simple and clear arrangement mode in whole cylindrical shell three dimensions that makes by helical arrangement.The antecurvature part in this outer end can be made of high-abrasive material, and for example carbide alloy, pottery, ultra-high molecular weight polyethylene etc. also can adopt the method for build-up wear-resistant alloy.

Though whole cylindrical shell can be made of being difficult for binding material, the present invention is that mixing drum is with being difficult for binding material for example stainless steel or ultrahigh molecular weight polyethylene work.Though whole cylinder inboard wall all can serve as a contrast to be difficult for binding material, only at the stirring section installing liner plate of cylindrical shell, its advantage is to reduce manufacturing cost in the present invention.Liner plate can be with being difficult for and the material that is stirred the thing bonding by humidification, as polytetrafluoroethylene (PTFE), polyethylene, ultra-high molecular weight polyethylene, stainless steel etc., traditional manufacture method is with screw, rivet or binding agent liner plate to be fixed in cylindrical shell or the mixing drum, also can adopt method of spray plating at inner barrel spraying plating polytetrafluoroethylene (PTFE), polyethylene or other non-caked material.

Vibrator can be contained in the top of cylindrical shell, also can be contained in the cylindrical shell side, can adorn one and also can adorn two, can certainly adorn more than two.But adorn one simple in structure and can make cylindrical shell produce the approximate circle vibration, help removing the barrel adhesion layer.The present invention adopts following air-humidification method when adopting vibrator: stop feedwater before vibrator starts, or stop simultaneously feeding water and charging, or back time-delay the stopping charging that stops to feed water, make scraped or adhesion layer that the moisture content that falls of shaking is high with from the dry dust that enters to barrel and/or comprise being stirred thing by humidification and mixing of flying dust near the cylindrical shell center, moisture content is reduced, the also corresponding reduction of adhesiveness can be removed adhesion layer effectively, can save energy water saving again.In addition, also can take following measure: by starting vibrator continuously or off and on before each shutdown and in whipping process, before the cylinder inboard wall adhesion layer is strong in time with its removing.Can certainly when starting vibrator, stop feed and continue feedwater, utilize vibration and water to clean barrel, but usually muddy water flow over, form secondary pollution, should not adopt.This structure also is applicable to existing dust humidifier is undergone technological transformation.

Said anti-bonding device also comprises the prone puddler in end, inwall is lined with the liner plate that is difficult for the binding material making or with being difficult for the mixing drum that binding material is made, with the three kinds of wherein any two kinds combinations of device of one or more vibrators on the shell that is contained in cylindrical shell, or adopt above-mentioned three kinds of devices simultaneously, mainly select, also be convenient to existing dust humidifier is undergone technological transformation according to the caking property of dust.

In order to reduce the resistance of puddler incision adhesion layer, the antecurvature part in the end of puddler is the conical or flat edge of a knife shape that head comes to a point, and the angle of inclination of the longitudinal axis of the edge of a knife and cylindrical shell is 0 ° to 60 °.When the edge of a knife when the discharging opening direction tilts, also have stirred the effect that thing hits to the discharging opening direction by humidification, can accelerate to be stirred thing effectively and discharge by humidification, reduce the material stock amount of inner barrel, reduce to stir resistance.If edge of a knife inclined in opposite directions partly then can strengthen mixing stirring action.But the edge of a knife corresponding to those puddlers of discharging opening on the shaft should be parallel with tubular axis, helps being stirred thing by humidification and discharge from discharging opening and avoid discharging opening to see plug.On a shaft, can only adopt a kind of in above-mentioned two kinds of prone puddlers in end, but adopting two kinds of puddler the bests simultaneously, and two kinds of puddlers should alternately be arranged.

The preferred plan of lining plate structure is to make full use of the sheet bending advantages of high strength, sheet material is curved external diameter put into cylindrical shell or mixing drum less than the cylindrical shape of cylinder internal diameter, after removing external force, sheet material is close on the inwall of cylindrical shell or mixing drum by its elasticity, the liner plate that promptly is difficult for bonding and connecting of cylindrical shell or mixing drum be utilize sheet material high resiliency and without fixtures such as bolt, rivet or binding agents, simple in structure, mounting or dismounting are convenient, especially can freely stretch without restriction during rising-heat contracting-cold.This method also is specially adapted to existing dust humidifier is undergone technological transformation.The thickness of sheet material determines that according to the diameter of cylindrical shell and the elasticity of material both having guaranteed has the enough power that is adjacent between sheet material and cylindrical shell or the mixing drum, guarantee that again the internal stress that is produced when sheet bending becomes cylindrical shape is no more than the allowable stress of material.

For the strong dust of adhesiveness, need bigger exciting force, the also corresponding increase of the amplitude of cylindrical shell.For satisfying the requirement of cylindrical shell large amplitude, cylindrical shell or mixing drum are bearing on the frame with the isolated supporting device and/or vibrating mass and do not install flexible sealing arrangement between the vibrating mass.The isolated supporting device guarantees that cylindrical shell or mixing drum have bigger amplitude, but the amplitude of complete machine is then less.The oscillating component of cylindrical shell and other do not need certain clearance between the vibrating mass, dust just may be overflowed from this gap, at vibrating mass and do not install flexible sealing arrangement between the vibrating mass, flexible sealing arrangement can prevent that dust from escaping for this reason, and does not influence the cylindrical shell vibration.Flexible sealing arrangement comprises flexible seal circle and clip, the flexible seal circle can use materials such as TR thin rubber, polyester canvas, asbestos canvas, artificial leather to make, preferably make bellow-shaped, clip is used for the flexible seal circle is separately fixed at vibrating mass and vibrating mass not.

If whole cylindrical shell all vibrates, owing between the batcher of cylindrical shell and charging aperture top relative motion is arranged, between charging aperture and feed pipe, establish the flexible seal circle for this reason, charging aperture comprises outer tube and interior pipe, interior pipe stretches in the feed pipe, one end of flexible seal circle is fixed on the charging aperture outer tube with clip, and the other end is fixed on the feed pipe with clip.When should guaranteeing to vibrate, the gap in the charging aperture between pipe and outer tube and the feed pipe can not collide.

If the shell portion ginseng is shaken, flexible sealing arrangement should be located between barrel and the mixing drum, mixing drum is bearing on the frame with the isolated supporting device, be fixed on the frame and stretch in the mixing drum to barrel, one end of flexible seal circle is fixed on the mixing drum with clip, and the other end is fixed on the flange to barrel with clip.This structure also is specially adapted to existing dust humidifier is undergone technological transformation.

The control vibrator starts or the electric current relay or the current sensor of cutting out usefulness is connected on the power line of shaft drive motor, be used to start or close the A.C. contactor of vibrator and the normal opened contact of electric current relay or current sensor links, in humidification mix process, when cylinder inboard wall adhesion layer when thickening firms gradually, the stirring resistance increases, the also corresponding increase of the electric current of shaft driving motor, when electric current surpasses setting value, electric current relay or current sensor action, the normal opened contact closure is used to start or closes the A.C. contactor action of vibrator, and vibrator starts, otherwise vibrator stops.Therefore vibrator is to start or stop with electric current relay or the current sensor size of current according to the shaft drive motor.The batcher of the magnetic valve of control water and control charging and vibrator interlock.Certainly, also can rule of thumb or by the size of current of ammeter observation shaft driving motor operate by artificial.

Cylindrical shell is tiltedly installed with and is beneficial to quickening and is stirred beyond the region of objective existence row by humidification, especially can accelerate to be effluxed by the vibrator adhesion layer that falls that shakes.Similar to jigging conveyer, vibrator tilts to install also can be accelerated to be stirred beyond the region of objective existence row by humidification.The prone puddler in this outer end also can be accelerated to be stirred beyond the region of objective existence row by humidification.

Though increased energy consumption after adding vibrator, because the frictional resistance of puddler and cylinder inboard wall adhesion layer reduces, total is still energy-conservation.Several dust humidifiers that production capacity is similar in production practices, wherein the power of a dust humidifier is 11KW, and stall often takes place, and changes 22KW into and just deals with problems; The power of an external dust humidifier of introducing is 18KW; Another dust humidifier is when the stronger dust of humidification caking property, and power is 7.5KW, because the vibrating motor of a 0.75KW of installing works well, stall does not take place.

The as above detailed description of being done, dust humidifier of the present invention, the prone puddler in the end, and/or the vibrator of installing on the shell of cylindrical shell, and/or under the effect of bond breaker, can make effectively near cylinder inner surface and/or scrape or the moisture content that falls of shaking is high is stirred thing by humidification and comprise being mixed by humidification stirring thing of flying dust near the cylindrical shell center from the adhesion layer of cylinder inner surface.Can also scrape or the moisture content that shakes is high by humidification that back time-delay the stopping feed that stops to feed water or stop to feed water when stirring thing makes it and mixes from the dry dust that charging aperture enters.The adhesion layer of cylinder inner surface can be scraped effectively or shake, and therefore, even the adhesiveness of handled dust is strong, can prevent that also the whipping performance that the cylinder inner surface adhesion layer is caused from descending.Since be just to form at adhesion layer but before strong as yet it is not shaken, so energy consumption is low, effective.And be to take the method that stops to spray water when starting vibrator, make to be scraped or the high adhesion layer of moisture content that falls that shakes mixes with the dry dust that enters from charging aperture, its humidity is reduced, adhesiveness and stir resistance also along with reducing and being easy to discharge from discharging opening.Therefore, when reducing and removing adhesion layer, can economize on water, energy-conservation.Do not emit dry ash and the few effect of amount of water when reaching behind the humidification dust emission, the caking property of dust has realized the purpose that prevents or reduce adhesion layer and make adhesion layer be easy to remove also along with reduction behind the humidification simultaneously.
