Abstract
The invention discloses a method for recycling active substances of a scrapped polar plate of a storage battery. The method comprises the following steps of: 1) immersing a scrapped lead-acid storage battery polar plate by pure water; 2) knocking away the active substances of the immersed polar plate in a wet state; 3) putting the knocked active substances into a grinding machine, adding the pure water, and grinding the active substances until the active substances are paste-like; and 4) discharging the ground paste-like active substances from the grinding machine, screening in the pure water to screen out possibly mixed grid broken strips, and immersing the screened active substances for later use. By adopting the structure, lead dust is not produced, so that the health of an operator cannot be damaged, and pollution to the surrounding environment is reduced; and furthermore, the purity of the active substances is higher after some impurities are screened out, and the performance of the recycled product is higher.
Description
Technical field
The present invention relates to storage battery field, is specifically a kind of recovery method of storage battery discarded pole plate active material.
Background technology
Storage battery due to its raw material be easy to obtain, cheap and use on have sufficient reliability, be widely used in various field.Storage battery small volume, therefore the size of its pole plate is also less, is all multi-joint design usually, and this sheet of multi-joint is called grid, and then on this grid, coats lead plaster form.In normal pole plate production process, usually have the positive plate of about 0.3% ~ 1% because point plate is cut partially, active material comes off, change into the reason such as bad and scrap.These pole plates scrapped usually can by as waste recovery, or the active material of pole plate is struck lower after again through grinding, sieve.But this method can produce a large amount of lead powder dust, can damage the healthy of operating personnel, meanwhile, also can to the environment of surrounding.
Summary of the invention
Technical problem to be solved by this invention is, provides one not produce lead powder dust, can not damage the healthy of operating personnel, also avoids the recovery method of the accumulator plate active material polluting surrounding environment
For solving the problems of the technologies described above, the recovery method of storage battery discarded pole plate active material of the present invention, it comprises the following steps:
1) first the accumulator plate pure water scrapped is soaked the time of more than 1 day;
2) active material of the pole plate after immersion is struck down in a wet state;
3) again the active material under striking is put into grinder, grind after adding pure water, active material is made to grind to form pulpous state, the weight at every turn adding the pulpous state active material that grinder carries out grinding is 100kg ~ 150kg, the weight of the pure water added is 20kg ~ 50kg, and the time of grinding is 1 hour; The grinder used comprises motor, base, urceolus, rotary main shaft and at least one cylinder, described motor is arranged in base, urceolus is connected on base, one end of rotary main shaft is connected with the output shaft of motor, rotary main shaft is positioned at urceolus, rotary main shaft is connected with transverse slat away from one end of motor output shaft, and transverse slat is vertical with rotary main shaft, and the two ends of cylinder are connected with transverse slat respectively by respective adjustable connecting plate mechanism; Described each adjustable connecting plate mechanism is by upper plate and lower plate composition, one end of upper plate and one end of lower plate all have long lumbar hole, the other end of upper plate is connected with transverse slat, the long lumbar hole of upper plate and the long lumbar hole of lower plate are connected by screw, and the other end of lower plate and one end of cylinder are rotationally connected; The inside of described cylinder is cavity, and cavity is built with fine sand; Described rotary main shaft is connected with scraper by scraper arm, and the tool bit part of scraper and the inner peripheral wall of urceolus offset;
4) after ground, the active material of pulpous state is discharged grinder, sieve through 100 orders in pure water, make the grid fault wall bar grizzl(e)y that may be mixed into leach, the active material after sieving soaks stand-by with pure water again, and requirement pure water soaks stand-by active material was finished in 3 days.
When carrying out active material recycling, each by lead powder amount 1% ~ 3% ratio add, now active material is by weight in wet base calculating, and these active materials will add before adding lead powder.
After adopting above method, the wet type absorption method that the present invention adopts with have compared with technology, have the following advantages: due to the active material on the accumulator plate scrapped is struck lower before soak through pure water, therefore, operate in a wet state; In addition, be also add pure water to grind during grinding; Therefore, in whole removal process, the active material of accumulator plate is in a kind of wet state all the time; So, on the one hand, lead powder dust can not be produced, thus the healthy of operating personnel can not be damaged, reduce the pollution to surrounding environment; On the other hand, after sieving goes out some impurity, the purity of active material is higher, and the properties of product after being reused are better.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
A recovery method for storage battery discarded pole plate active material, it comprises the following steps:
1) first the accumulator plate pure water scrapped is soaked;
2) active material of the pole plate after immersion is struck down in a wet state;
3) again the active material under striking is put into grinder, grind after adding pure water, make active material grind to form pulpous state;
4) after ground, the active material of pulpous state is discharged grinder, sieve in pure water, make the grid fault wall bar grizzl(e)y that may be mixed into leach, the active material after sieving soaks stand-by with pure water again.
From the structural representation of the grinder shown in Fig. 1 and Fig. 2, described step 3) in, the grinder used comprises motor 7, base 9, urceolus 3, rotary main shaft 1 and at least one cylinder 8, described motor 7 is arranged in base 9, urceolus 3 is connected on base 9, one end of rotary main shaft 1 is connected with the output shaft of motor 7, and rotary main shaft 1 is positioned at urceolus 3, and the axial two ends of described cylinder 8 are connected with the other end of rotary main shaft 1 respectively.Described rotary main shaft 1 is connected with transverse slat 2 away from one end of motor 7 output shaft, and transverse slat 2 is vertical with rotary main shaft 1, and the two ends of cylinder 8 are connected with transverse slat 2 respectively by adjustable connecting plate mechanism.
