Abstract
The invention relates to the improvement of cooling, oxidative supplying wind and elevating powders of the air classification-type drum lead powder machinery. It is characterized in that: the cooling spray liquid extends into the drum along an axial. The feed and air inlet of the drum locate inside the encloser. Lead shot feeding device extending out of the encloser is at the feed inlet. The air inlet is at the discharge end or near discharge end. Several extending conical separating plates with pointed cones orientating rotation direction are set radial alternatively on the roller inwall. Direct cooling of the lead shot has small hysteresis effect and high precision of temperature control. The error of temperature control is between +-1deg.C. The produced lead powder has small oxidation extent fluctuation. After whistle stop, water or vapor contacts with the lead powder, which accelerates the oxidation rate of the lead shot (powder) and increases the milling productivity. It can increases 5-8% yield than the indirect cooling. The oxidative supplying wind is heated through the interlayer between the roller and the encloser and enters roller. It has stable supplying wind temperature, good oxidation quality of lead powder and stable oxidation rate. The conical separating plates can assure normal raises of lead powder without fan. Compare to lead powder machinery with the same productivity, it has simple structure and can save about 15% of the total power.
Description
Technical field
The present invention relates to a kind of winnowing type drum lead-power machine, relate in particular to that lead-power machine cools, the improvement of oxidation air feed and powder spreading.
Background technology
Wind-sorting drum lead-power machine such as Fig. 1 are to produce the special equipment of battery with lead powder.Pulverizing process lead button (or lead) 9 is in cylinder 4 rotary courses, and collision, friction oxidation become lead powder 10 mutually, makes temperature rising in the cylinder, and while lead button surface contacts oxidized at a certain temperature with the air that enters cylinder be again a kind of exothermic reaction.Above-mentioned pulverizing process all can produce a large amount of heat, makes that temperature constantly rises in the lead-power machine cylinder, and the rising of temperature further accelerated the lead button oxidation rate again, and it is faster to make that temperature raises.If temperature in the cylinder is not controlled, too high temperature can make lead button fusing, caking, even can't produce continuously; Too high in addition temperature also directly influences the important indicator-oxidizability of lead powder.Therefore, be production continuously and stably, and obtain the stable battery lead powder of oxidizability that must control the lead powder built-in temperature in claimed range, and the lead button temperature is stable more in the cylinder, the oxidizability of lead powder is also stable more; Secondly, control the lead button different temperatures, can obtain the lead powder of required different oxidizabilities.
Temperature controlling in the cylinder can be kept thermal balance in the cylinder by increasing the air inducing amount in theory, and reduce the lead button addition, and temperature is at claimed range in the index drum.Yet increase the air inducing amount, can make the high lead powder of bulky grain, apparent gravity, cause the lead powder particle of production big, the apparent gravity height with the sucking-off of air inducing air-flow; Reduce the lead button addition and control temperature rise, when lead button was reduced to some, the interior lead button friction of cylinder was ground and is reduced, and it is temperature required that the heat of generation can not be kept the interior oxidation of cylinder again, and the production degree of oxidation of lead powder is low, output is little.It is reinforced that Chinese patent CN200620025487.X discloses a kind of employing automatic control, evenly reinforced by the control lead button, reduces temperature fluctuation in the cylinder.This mode realizes very complicated, needs to be grouped into weighing system by increasing LOAD CELLS, mechanical part and electric control part, and it is more not only to cause the lead-power machine cost to increase, and owing to control is complicated, fault is increased, and causes and produces instability.Therefore actual above-mentioned dual mode is not used substantially.
Water is a kind of good cooling medium, is used to cooling in many occasions.Yet lead powder is extremely avoided water and humid air, after lead powder is met water and humid air, can cause leady oxide aggravation temperature to raise, the temperature that raises has further been aggravated leady oxide again, and it is faster to make that temperature raises, thereby causes oxidized yellow lead or the red lead of becoming of lead powder, therefore though people know water and can lower the temperature, but really dare not directly add water for cooling to lead powder in system lead powder process, this has formed a kind of technology prejudice, and never the someone breaks through for a long time.Therefore, interior lead button (powder) temperature of prior art control lead-power machine cylinder, all unique employing is forced cooling indirectly to the cylinder outer wall water spray, thereby makes interior lead button (powder) temperature of cylinder controlled.Fig. 1 (the Chinese patent CN2657827 that comprises Chinese patent CN2291236 and applicant application) has shown that a kind of prior art is to cylinder spray cooling mode, between lead-power machine swing roller 4 and outer cover 3 interlayers, valve control spray equipment 8 is set, add hydrofuge fan 7 on the outer cover, cooling water 5 is controlled the cylinder outer wall spraying cooling by valve 6, temperature is then detected by the thermal detector 11 that is arranged in the cylinder in the cylinder, show or FEEDBACK CONTROL water spray intensity, reach lead button 9, lead powder 10 temperature in the control lead-power machine cylinder.This kind is by making lead button (powder) mode that cools indirectly to cylinder outer wall water spray, its deficiency is: lead button (powder) cooling is to realize by the cylinder outer wall cooling in the cylinder, again by the discharge gate thermometric, control cool water shower amount, cooling and temperature control hysteresis effect are bigger, temperature control is the most accurate also to be had ± 2 ℃ of errors, and cause interior lead button (powder) true temperature departure of cylinder and fluctuation big, produce degree of oxidation of lead powder and fluctuate still bigger; And the cylinder outer wall temperature is higher, usually more than 100 ℃, makes the cooling water that is sprayed onto cylinder surface become water vapour immediately, and therefore need install the hydrofuge fan additional discharges outer cover with it, has worsened production environment.
In addition, the required oxygen of prior art lead button oxidation is by high pressure positive blower 12 charging, the air inlet 1 of natural wind outside being arranged on case 3 to be sent into cylinder.The lead button oxidation is big to the air requirements amount, need to be equipped with the bigger high pressure positive blower of power, with the 24T/D lead-power machine is example, the air feed power of fan requires about 18 kilowatts, for making the even cylinder domestic demand of air feed air distribution pipeline and nozzle (not providing among the figure) is set, and has not only increased equipment appurtenance and complexity, increased equipment cost, and the oxygen supply consumed power is big, and the blower fan operating noise is big, and production environment is poor.Secondly, because of blowing to lead button wind-warm syndrome degree, can directly influence the oxidizability of lead powder, usually require EAT in 20 ℃～70 ℃ scopes, the degree of oxidation of lead powder of producing is more stable, and actual owing to reach seasonal variations round the clock, the temperature of natural wind can not be constant and can fluctuates thereupon, sometimes the minimum temperature of requirement also can occur being lower than, thereby cause the oxidizability fluctuation of lead powder bigger, quality is extremely unstable.For eliminating the wind-warm syndrome fluctuation that the variations in temperature reach season round the clock causes, the oxidizability of steady production lead powder, oxidizability when especially environment temperature is low, can only set up heater (not providing among the figure) in the inlet and/or the outlet of high pressure positive blower, with this constant ventilation temperature, make the natural wind temperature of feed roller satisfy the degree of oxidation of lead powder requirement; Or reduce and supply with intake.Though the former can keep EAT, guarantee EAT in claimed range, because wind supply quantity is bigger, therefore require heater power also bigger, cause energy consumption and equipment cost further to increase; The latter passes through to reduce intake, though can improve oxidizability, the one, troublesome poeration needs often adjust with the temperature fluctuation, and the 2nd, intake reduces, and has reduced the lead-power machine production capacity, also can increase the lead powder manufacturing cost.
Besides, existing lead-power machine lead oxide powder 10 is discharged, and is to send into high pressure draught by high pressure positive blower to cylinder, lead powder is blown afloat separate with lead button 9 and be suspended in (genus is praised powder) in the cylinder, is discharged outside the cylinder by discharge end 2 negative pressure exhausting, thereby realizes producing continuously.This kind need equally not only need the bigger high pressure positive blower of power by sending into high pressure draught powder spreading mode, increase the powder spreading power consumption; And need complicated blower and the nozzle (not providing among the figure) of configuration in cylinder, and auxiliary equipment is many, and complex structure is installed loaded down with trivial details.And the high-power blower fan exists operating noise big, poor working environment equally.Especially, in the lead-power machine running, as take out the powder negative-pressure air fan and damage, also can lead powder be blown out outside the cylinder contaminated environment because of the malleation of powder spreading.
Above-mentioned deficiency makes wind-sorting drum lead-power machine, and not only production consumed power is bigger, and quality of production instability, and fluctuation is big.Therefore still having is worth improved place.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of simple in structure, and energy-conservation, Controllable Temperature is good, and temperature control is accurate, and the oxidation ventilation temperature is not subjected to reach round the clock seasonal variations to be influenced, without blower fan also powder spreading automatically, produce the stable wind-sorting drum lead-power machine of degree of oxidation of lead powder.
The object of the invention realizes that mainly improving one is directly to move in the swing roller cylinder cooling cooling hydrojet (water), is direct cooling thereby become lead button (powder) cooled indirectly; The 2nd, cylinder oxidation air feed is directly entered outward by lead-power machine, change into through entering after the interlayer preheating between cylinder and case, for example make cylinder charging, air inlet, by lead-power machine case external contracting (case and cylinder interlayer) to case, and stretching out lead button feeding device outside the case in charging, air inlet setting, case discharging or nearly discharge end (feed end dorsad) have air inlet; The 3rd, at the radially alternate conical separator sediment element that stretches out that some pointed cones are set towards direction of rotation of swing roller internal face, make cylinder in rotary course, by of the centrifugation of conical separator sediment element two inclined-planes, reach pulverizing back lead powder and separate the powder spreading of realization lead powder with lead button material.Thereby overcome the prior art deficiency, realize the object of the invention.Specifically, wind-sorting drum lead-power machine of the present invention comprises swing roller and more fixing case outward, and cooling liquid-jet device and thermal detector is characterized in that cooling off hydrojet and extended in the cylinder by the cylinder axially open; Cylinder charging, air inlet are positioned at case, and charging aperture has the lead button feeding device that stretches out outside the case, and case discharging or nearly discharge end have air inlet; The inner wall of rotary drum face diameter is to the alternate conical separator sediment element that stretches out that some pointed cones are set towards direction of rotation.
The said cooling cooling of the present invention hydrojet (water) can be a water, can also be other easy gasifying liquids of lowering the temperature, and wherein water is the simplest, economic a kind of cooling medium.
Said cooling water spray is extended in the cylinder by the cylinder axially open, can be at drum shaft to two or one end perforate, will cool off sparge pipe and stretch into cylinder, also can be to cool off sparge pipe directly to stretch into cylinder by charging, air inlet and/or exhausting discharge gate.The present invention preferentially selects the latter for use, can be omitted in cylinder end face opening separately.
Test finds, because of temperature in the lead-power machine cylinder greater than the vapourizing temperature of cooling liquid, spray into and be vaporized into steam immediately after cooling fluid enters cylinder, and under exhausting negative pressure discharge fan action, discharge outside the cylinder by discharging opening rapidly, thereby can be in the cylinder inner accumulated; Cylinder is in continuous rotation in addition, and its cooling effect has limited temperature and further raise, and therefore can not cause the lead powder burning to become yellow lead or red lead, thereby overcome people's technology prejudice, can directly lower the temperature to lead button (powder).Cooling water is directly directly lowered the temperature to lead button (powder), makes the temperature control hysteresis effect reduce greatly, temperature-controlled precision can reach ± 1 ℃ in, the oxidizability of having guaranteed to produce lead powder is stable.By thermometric FEEDBACK CONTROL injection flow rate, can obtain required lead button (powder) temperature, thereby obtain different oxidizability lead powder.
In addition, according to above-mentioned design of utility model and technical scheme, charging, air inlet branch are arranged, and only contract in the air inlet.
Offer air inlet on the case, for fully making air intake obtain heating, a kind of better is to make it as far as possible away from air inlet, better is to make case air inlet and cylinder air inlet be divided into drum shaft to both sides therefore, be that the cylinder air inlet is located at cylinder one end face, the case air inlet is located at opposite case end face.
Charging aperture stretches out the outer lead button feeding device of case, effect is case to be treated as a stranger the powder process lead button send in the swing roller, promptly to the swing roller feed, it can adopt multiple mode to realize, for example can be that an end stretches into the cylinder charging aperture, an end stretches out the outer level of case or the circulation material conveying band of approximate horizontal, also can be perpendicular or the oblique charging conduit that passes case, and stretch into charging aperture swash plate combined feed device, for example similar cement mixer feed arrangement.
Said conical separator sediment element can be right angle, acute angle or obtuse triangle, also can criteria of right and wrong taper, and for example arc taper has centrifugation equally.
The present invention radially is provided with conical separator sediment element, and test shows its quantity, extension elongation, can influence output, oxidizability and the apparent density of lead-power machine.Test comparison shows that, conical separator sediment element is to centre of the drum's extension elongation, be suitably 50～250mm, if conical separator sediment element extends radially out too short, powder spreading effect and effect are not clearly, but extend radially out longly, can cause again in the cylinder that control of temperature difficulty or ease or lead powder apparent density are higher, influence the lead powder quality.Conical separator sediment element quantity, test are relatively comparatively more suitable with 5～10, and the very few powder spreading weak effect of quantity too much also can cause bowl temperature to be difficult to control.
Wind-sorting drum lead-power machine of the present invention, to cool off sprays water directly stretches into spray cooling in the cylinder owing to adopt, the cooling water vapor, and discharge outside the cylinder by discharging opening rapidly, directly heat in the cylinder to be taken away, this directly lowers the temperature to lead button (powder), the temperature control hysteresis effect is little, temperature-controlled precision height, temperature control can reach ± 1 ℃ in, the degree of oxidation of lead powder fluctuation of producing is little; Test is found in addition, and cylinder is directly sprayed water, and the short stay of water or steam contacts with lead button (powder), has quickened the oxidation rate of lead button, has increased the powder process production capacity, can cool off the output that increases about 5-8% more indirectly.Secondly, the oxidation air feed sucks case and cylinder interlayer under the discharge negative pressure, through cylinder and the heating of case interlayer, enter cylinder again, ventilation temperature is stable, not being subjected to reach round the clock seasonal variations influences, not only avoided outside air directly to enter cylinder and caused the ventilation temperature fluctuation, influenced the lead powder quality, the leady oxide quality is good, oxidizability is stable, and interlayer heating air feed can also take away the heat that produces at pulverizing process, chilling roll also had positive role, but also can omit high-power air feed machine, affiliated facilities such as air-supply pipeline and air feed heater, equipment cost and power consumption have been reduced, save the energy, reduced the powder process cost, do not influenced production capacity, do not have the blower fan operating noise, also improved working environment greatly.Especially thoroughly eliminated and taken out the powder negative-pressure air fan and damage, the lead powder that former malleation air feed may the bring pollution that leaks.Besides, the alternate setting of inner wall of rotary drum face to the center stretch out, pointed cone is towards the conical separator sediment element of direction of rotation, can also can guarantee still under the blower fan that lead powder normally kicks up omitting, and has energy-conservation, abridged edition and noise reduction effect equally.Test is compared, and identical production capacity lead-power machine can be saved general power about 15%.
