Abstract
The utility model discloses a lead powder refining and grading system. An airflow grading machine system is arranged between a lead powder machine (5) and lead powder hoppers (6), the lead powder machine (5) is connected with an inlet of the airflow grading machine system, a fine material outlet at the upper part and a coarse material outlet at the lower part of the airflow grading machine system are respectively provided with one lead powder hopper (6), the lead powder hopper (6) for collecting fine powder is connected with a paste collecting machine (7) for making positive lead paste, and the lead powder hopper (6) for collecting coarse powder is connected with a paste collecting machine (7) for making negative paste. The utility model ensures that particle sizes of the active lead powder at a positive electrode and the active lead powder at a negative electrode are distributed more narrowly and uniformity of the active lead powder is improved, thereby improving the utilization rate of the active powder of a battery and prolonging the service life of a battery pack while lead consumption is reduced. Because the yield of the lead powder machines is in positive correlation with the average particle size of the lead powder, after the refining and grading device is additionally provided, the yield is not influenced while the quality of the lead powder is improved.
Description
Technical field
The utility model belongs to the lead acid accumulator field, specifically, relates to the system of processing of the refinement of a kind of lead acid accumulator lead powder, classification.
Background technology
Under the present lead powder production technology; The relative broad of particle size distribution of the lead powder that lead-power machine is produced; The smear that normally directly is used for the battery plus-negative plate plate; Require relatively low negative pole not distinguish in technology and equipment reason to have relatively high expectations anodal of lead powder average grain diameter and particle size distribution with to lead powder average grain diameter and particle size distribution in the SC service ceiling of lead powder; So limited the inhomogeneity lifting of lead powder, also restricted the lead powder specific aim and used further lifting battery uniformity, life-span and lead loss index.
The battery of many serial connections of lean solution formula AGM to battery inhomogeneity require increasingly high; Around inhomogeneity raising, people battery production water sheet and aspects such as smear weight, curing and chemical synthesis technology, battery capacity and voltage screening have obtained obvious progress; Along with the expansion of lead-acid battery in railway, communication, electric motor car and hybrid vehicle application; The voltage of battery develops to height, requires the uniformity of battery further to promote.The inhomogeneity lifting of the pole plate active matter material lead powder of lead acid accumulator is very favorable to the consistency raising of battery.Lead powder is carried out refinement; Satisfy the anodal requirement narrower to lead powder average grain diameter and granularity (owing to the negative pole utilance far above positive pole; Be met in the time of with meal); Make the particle size distribution of both positive and negative polarity active matter lead powder narrower, the active matter uniformity promotes, and then life-span of improving the utilance of the active matter of battery, when reducing lead loss, improving battery pack.
The utility model content
For solving above technical problem, when the purpose of the utility model was to provide a kind of processing lead powder, lead powder was further divided into the system of processing of the meal of the fine powder that is used for positive plate and negative plate through refinement.
The utility model purpose is achieved in that the system of a kind of lead powder refinement and classification; Comprise lead-power machine (5), lead powder bucket (6), close cream machine (7); Its key is: be provided with the gas flow sizing machine system between said lead-power machine (5) and the lead powder bucket (6); Said lead-power machine (5) is connected with gas flow sizing machine system import; Outlet is connected a lead powder bucket (6) respectively with the bottom coarse fodder in this gas flow sizing machine system top fines outlet, and the lead powder bucket (6) of collecting fine powder connects the cream machine that closes (7) of making positive lead plaster, and the lead powder bucket (6) of collecting meal connects the cream machine that closes (7) of making negative lead plaster.Lead pig is pulverized by lead-power machine (5) and is obtained lead powder, and lead powder is divided into two kinds of thicknesses through the gas flow sizing machine system with the lead powder that gets into, and the lead bullion powder gets into respectively in the different hoppers with thin lead powder; Adorn the hopper of thin lead powder lead powder is sent into the cream machine that closes, add the anodal auxiliary material of sour water simultaneously and mix and make positive lead plaster; The hopper of dress lead bullion powder is sent lead powder into the cream machine that closes, and adds sour water negative pole auxiliary material simultaneously and mixes and make negative lead plaster.
Said flow grader system comprises charger (1), grader (2), bag collector (3) and air inducing unit (4) composition; Wherein charger (1) is communicated with grader (2) lower inlet through feed pipe; This grader (2) top is communicated with bag collector (3); Said grader (2) bottom is the outlet of lead bullion powder, and the lower part outlet of said bag collector (3) is thin lead powder outlet, and said air inducing unit (4) is communicated with bag collector (3) through pipeline.The lead powder that charger (1) gets into is got into by feed pipe under air inducing unit (4) draft effect; Dispersion plate in the classified machine (2) spreads in the air-flow that rises; The air-flow of lead powder carried under one's arms rises to the classification part, and getting into then through guide vane, rotor carries out classification; Guide vane can make air-flow and lead powder particle produce gyration, presorts level, and captures the coarse granule that is thrown away by rotor, and the speed of air-flow is evenly distributed on the height of whole rotor.Lead bullion powder particles by guide vane captures is fallen on the meal cone, discharged by the lead bullion powder outlet of grader (2), and thin lead powder particle and air-flow gets into the rotor middle part through rotor blade, are sent to bag collector (3) by the fine powder outlet; Grader can be confirmed the thickness lead powder ratio of output in the lead powder amount that positive and negative green plate need be used.
Key data contrast table before and after table 1, the lead powder classification
3) because the grading wheel of high speed rotating to the collision of lead powder, partly has lead oxide pulverizes and the positive effect of depolymerization.The fine powder that will make positive plate powder with classification is come out is compared; The thicker D90 of raw material lead powder of lead-power machine output drops to 16.0 (22.85) um by 25.05um; D98 drops to 23.95 (35.34) um by 43.42um; Average grain diameter is reduced to 6.04 (8.38) um by 12.43um, and it is 5.55 (4.96) m2/cm3 that the surface area of while lead powder is increased substantially by 0.85m2/cm3; The meal that is used for negative plate that grader is told is thinner than raw material lead powder, and surface area increases.
Experiment shows the purpose that adopts the one-level grader just can reach the refinement and the classification of lead powder.
Beneficial effect: the utility model is in the process of system's processing lead powder; Simultaneously as required lead powder is carried out abundant refinement; Thickness grading again; Can reach easily and be suitable for the appropriate refinement that purposes needs and the classification of arbitrary proportion; Fully satisfied positive pole to lead powder average grain diameter and the narrower requirement (negative pole is met simultaneously) of granularity, made that the particle size distribution of both positive and negative polarity active matter lead powder is narrower, the active matter uniformity promotes, and then the life-span of improving the utilance of the active matter of battery, when reducing lead loss, improving battery pack.Because the output of lead-power machine and the average grain diameter positive correlation of lead powder, output can not be affected when can reach the raising of lead powder quality behind interpolation refinement and the grading plant.
