Abstract

The invention provides a lithium battery cathode material packaging process. The process includes the following steps that zero-valent iron impurities in a lithium battery cathode material are removed through an electromagnetic iron remover and the material then enters a stock bin through a feeding port of the stock bin so as to be temporarily stored and fed to a vibration feeder through a rotary feeding valve via a discharging port of the stock bin; a packaging bag arranged on an air bag clamping mechanism in a sleeving mode is fed through the vibration feeder, so that the weight of the packaging bag reaches 85% to 95% of the rated weight, the feeding speed is then reduced till the weight of the packaging bag reaches the rated weight, and weighing operation is finished; the weighed full bag is conveyed to a recheck conveyor and rechecked through a weight recheck scale; the packaging bag which is rechecked to be qualified is continuously conveyed to a thermal sealing conveyor, thermally sealed through a vacuumizing thermal sealing machine and conveyed to a stack conveyor, and after being placed in a barrel and sealed through a cover, the packaging bag is stacked. By the adoption of the lithium battery cathode material packaging process, the zero-valent iron impurities in the lithium battery cathode material can be reduced, packaging accuracy is improved, product loss is reduced, and dust pollution is controlled.

Description

The technology of the package of anode material of lithium battery
Technical field
The present invention relates to packing technique field, specifically, relate to a kind of technology of the package of anode material of lithium battery.
Background technology
Lithium cell has lightweight, nontoxic, nonhygroscopic, Heat stability is good, good cycle, and safety performance is given prominence to and the feature of environmentally safe, and be subject to global extensive concern, its application prospect is very wide.Anode material of lithium battery occupies the ratio of more than 40% in the total cost of lithium cell, and the performance of positive electrode directly affects the property indices of lithium cell; Positive electrode resource-constrained, expensive and exist pollute.This just proposes very high requirement to the technology of the package of anode material of lithium battery.In existing lithium cell technology of the package, the fe impurity in anode material of lithium battery is not processed, and fe impurity can have influence on the safety performance of lithium cell.In addition, also there is Accuracy of Packaging in existing lithium cell technology of the package low, the problems such as dust pollution is large.
Summary of the invention
The object of this invention is to provide a kind of technology of the package of anode material of lithium battery, the fe impurity in anode material of lithium battery can be reduced by this technique, improve packaging accuracy rate, reduce product loss, control dust pollution.
The technical scheme realizing the object of the invention is: a kind of technology of the package of anode material of lithium battery, and processing step is as follows:
1), anode material of lithium battery removes fe impurity in anode material of lithium battery through electric magnetic iron remover, then enters buffer memory feed bin from the inlet point of feed bin, then enters vibrating feeder from the discharging opening of feed bin by rotatory feeder valve;
2), vibrating feeder to the packaging bag rapid loading be sleeved on air-bag clipping mechanism to 85 ~ 95% of rated weight, then slow down feed progress, reaches specified weight of weighing, complete and weigh until reinforced;
3), by completing the purseful after weighing delivering to reinspection conveyer, rechecking scale by weight and rechecking;
4), by the qualified packaging bag of reinspection continue transported to heat seal conveyer, after vacuumizing heat-sealing machine heat seal, deliver to stacking conveyor, barrelling capping allows rear piling.
Further, feed in raw material in process at vibrating feeder to the packaging bag be sleeved on air-bag clipping mechanism, filter the positive electrode in dust laden air by dust exhaustor.
Further, step 3) in be manually deliver to reinspection conveyer by roller conveyor by completing the purseful after weighing.
After have employed technique scheme, the present invention has following beneficial effect: anode material of lithium battery is first through electric magnetic iron remover process, electric magnetic iron remover can produce high magnetic flux field, the acuter angles on screen cloth grid top and slight vibration can while the powders of dispersion flows difference, small iron contamination is efficiently removed by the screen cloth be magnetized, reduce the iron contamination content entering the positive electrode of packaging process, guarantee the safety of lithium cell.Vibrating feeder can realize stepless 0 ~ 100% delivery rate by adjustment input voltage, guarantees to pack accuracy rate.Feed in raw material in process at vibrating feeder to the packaging bag be sleeved on air-bag clipping mechanism, the positive electrode in dust laden air is filtered by dust exhaustor, dust pollution can be reduced simultaneously, reduce environmental pollution, guarantee working environment cleans, recycle the positive electrode filtered down, reduce the wasting of resources.

Detailed description of the invention
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation.
As shown in Figure 1, a kind of technology of the package of anode material of lithium battery, processing step is as follows:
1), anode material of lithium battery removes the fe impurity in anode material of lithium battery through electric magnetic iron remover 1, then buffer memory feed bin 2 is entered from the inlet point of feed bin, if feed bin Weighing module judges that feed bin is full, stop charging, in feed bin, the anode material of lithium battery of 2 enters vibrating feeder 4 from the discharging opening of feed bin 2 equably by rotatory feeder valve 3, and rotatory feeder valve 3 can by adjustment reductor speed-ratio regulation anode material of lithium battery flow velocity;
2), packaging bag artificial bagging is on air-bag clipping mechanism 6, fixed packet pack heaved by air bag, pipe capsule valve 5 is opened, vibrating feeder 4 to the packaging bag rapid loading be sleeved on air-bag clipping mechanism to 90% of rated weight, then slow down feed progress, reaches specified weight of weighing, complete and weigh until reinforced, air bags, releases bag;
3), manually deliver to reinspection conveyer 7 by roller conveyor by completing the purseful after weighing, recheck scale 8 by weight and recheck, if recheck nonconformity, it is qualified to be manually adjusted to, and continues circulation;
4), by the qualified packaging bag of reinspection continue transported to heat seal conveyer 9, after vacuumizing heat-sealing machine 10 heat seal, deliver to stacking conveyor 11, barrelling capping allows rear piling.
As shown in Figure 1, feed in raw material in process at vibrating feeder to the packaging bag be sleeved on air-bag clipping mechanism, filtered the positive electrode in dust laden air by dust exhaustor 12, ensure that working environment cleans, recycle the positive electrode filtered down, reduce the wasting of resources.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
