Description

The refuse battery processing unit

The utility model belongs to the refuse battery treatment facility.

Along with increasing of portable electronics, use the quantity of battery also sharply to increase, refuse battery also is on the rise to the pollution of environment like this, because heavy metal and hardening agent manganese dioxide such as mercury, mercury chloride, calogreen, cadmium, lead, zinc are arranged in the refuse battery, also has copper and charcoal.Metal pair environmental hazard maximums such as mercury, mercury chloride, calogreen, cadmium, lead wherein, as refuse battery being burnt the meeting contaminated air, bury meeting polluted underground water and soil, and this two makes all thorough contaminated solution problems of kind of way, contaminated environment is a problem that is difficult to solve for a long time.

The purpose of this utility model be design a kind of can make refuse battery free from environmental pollution, and can reclaim the refuse battery processing unit of heavy metal wherein.

For achieving the above object, the utility model has adopted following technical scheme: comprise that top is provided with charging aperture, the bottom is provided with the floss hole of band obstruction and the heating kettle that the upper end is provided with destilling tower; The outlet of destilling tower links to each other with the product groove through the cooler of two polyphones with pipeline, and product groove top has pipeline to link to each other with vacuum pump, and the vacuum delivery side of pump links to each other with acid tank, and the back of last acid tank is the alkali groove; In heating kettle, be equipped with and be fixed with paddle, bottom by rotating shaft, rotating shaft middle part the blender that knife rest and scraper are formed is installed, it is characterized in that at the bottom of the heating kettle it being wedged bottom to the floss hole inclination; In heating kettle suitable for reading, be equipped with the circular sieve plate identical with still mouth internal diameter; On rotating shaft of stirrer top, be equipped with the scraper plate oar below sieve plate, the knife rest of rotating shaft bottom and scraper are for flexibly connecting.

The utility model is refuse battery to be placed in the heating kettle heat, fusing point according to several heavy metal species such as the mercury in the battery, mercury chloride, calogreen, lead, cadmium, zinc is different with boiling point, separate recovery, refuse battery is through long-term storage, calogreen is wherein just separated out part mercury and mercury chloride, therefore contain mercury, mercury chloride, calogreen in the refuse battery, when being heated to 400 ℃, above-mentioned three kinds of materials all are evaporated out (356.9 ℃ of mercury boiling points, 304 ℃ of mercury chloride boiling points, 400 ℃ of distillations of calogreen.) be cooled to mercury, mercury chloride and calogreen, continue cooling through the 2# cooler again through the 1# cooler, after acid tank absorbs remaining mercuryvapour, guarantee whole recovery of mercury, the mercuric nitrate of generation can be done pharmaceutical raw material, nitrogen oxide gas in the gas all absorbs through aqueous slkali.The complete conformance with standard of the gas of Pai Chuing like this, at last; Cadmium in the battery, lead, zinc just utilize different these characteristics of fusing point to separate recovery, and iron reclaims with magnetic selection method, and copper, charcoal reclaim with hydrometer method.It is simple in structure, and is easy to operate, and practicality had both solved the battery pollution problem, has reclaimed various useful components in the battery again, kills two birds with one stone.

Be described further below in conjunction with drawings and Examples.

As shown in Figure 1 and Figure 2, heating kettle of the present utility model 2 tops one side has charging aperture 1, bottom one side has floss hole 4, in floss hole 4, have and stop up 11, outlet at still 2 upper end destilling towers 10 links to each other with 1# cooler 5 with pipeline, and this cooler bottom has drain hole, bottom one side to have pipeline to communicate with 2# cooler 9, cooler 9 usefulness pipelines link to each other with product groove 6, vacuum pump 7, acid tank 8 and alkali groove 20 successively, and product groove 6, each acid tank 8 and alkali groove 20 are enclosed; Be provided with the motor 3 that drives blender on heating kettle 2 tops, this blender is made up of rotating shaft 13, the grader leveling blade oar 21 on axle 13 tops, a plurality of scrapers 16 of paddle 14 and bottom at middle part; On axle sleeve 24 lateral walls of rotating shaft 13 lower ends, three knife rests 15 and coupled three to be installed at least equably scraper 16, scraper 16 be profile of tooth by 18 blade 17 at the bottom of the still; 18 center at the bottom of still is erect locating shaft 19 is installed, and axle 19 inserts in the axle sleeve 24; 18 gradient is 10-15 ° at the bottom of the heating kettle.

Fig. 3 is the structural representation of sieve plate.Sieve plate 22 is filters that sieve aperture 23 is arranged, and its external diameter is identical with still 2 internal diameter sizes suitable for reading, and its effect is to block paper scrap to enter cooler 5, stops up for preventing sieve aperture 23, is equipped with scraper plate oar 21 below sieve plate 22, with foreign material such as removing paper scraps.

Fig. 4, Fig. 5 are the structural representations that stops up.Obstruction 11 in the floss hole 4 is a cylindrical metal stopper, within it by lower wall one side, have a pod apertures 12 vertically, and the stopper shutoff arranged, obstruction 11 and pod apertures stopper are sealed condition during operate as normal, during discharge opeing attitude metal, open the pod apertures stopper, just open at the discharge solid matter and stop up 11.

According to last art design, the inventor manufactures experimently a refuse battery processing unit.Still 2 high 2m, diameter 1.5m, destilling tower 10 diameter 200mm, high 800mm, 18 to 15 ° of floss hole 4 inclinations at the bottom of the still, three knife rests 15 are installed on the axle sleeve 24 equably, and flexibly connect scraper 16 with bearing pin, cutter 16 wide 250mm have stepped tooth on the blade 17, and motor 3 is 3KW.

Treatment process process below in conjunction with the description of drawings refuse battery:

Earlier iron powder is sent in the still 2 by charging aperture 1, the heating of still 2 bottoms, blender work, when still 2 temperature reach 200 ℃, add the refuse battery of pulverizing, make wherein manganese dioxide and iron powder reaction, so as not to the manganese dioxide etching apparatus, simultaneously, start vacuum pump 7, make pressure in the still 2 be controlled at-scope of 100 ± 20mm water column in, when treating that temperature rises to 380 ℃ in the still 2, should slowly be heated to 400 ℃, in this process, mercury, mercury chloride and calogreen become gas gradually, enter 1# cooler 5, be cooled to mercury, mercury chloride and calogreen, the cooler outlet temperature is controlled at below 250 ℃, makes mercury become liquid, mercury chloride, calogreen all is solid-state, reclaim from drain hole,, continue cooling through 2# cooler 9 again for reducing the content of mercury in the gas, gained mercury flows into product groove 6, remaining mercuryvapour is absorbed by the nitric acid in the acid tank 8, and the aqueous slkali of nitrogen oxide in alkali groove 20 in the last gas absorbs, and it is just up to standard fully to discharge gas like this.

For guaranteeing mercury, mercury chloride and calogreen all gasify, the still temperature stops heating in the time of will reaching 450 ℃, vacuum pump 7 quits work simultaneously, but blender will work on, when treating still temperature drop to 325 ℃, pod apertures 12 at the bottom of the still in the obstruction 11 of floss hole 4 flow out liquid cadmiums (every 320.9 ℃ of fusing points), when being heated to 330 ℃, pod apertures flows out liquid lead (327.4 ℃ of plumbous fusing points), is warming up to 420 o'clock pod apertures and flows out liquid Zn (419.4 ℃ of zinc fusing points), stops heating this moment, when treating still temperature drop to 100 ℃, discharge residue, the magnet sucking-off of irony wherein, copper, charcoal sifts out by the proportion difference, probationary certificate, handle refuse battery with this device, not only nuisanceless but also reclaimed useful component, economic benefit and social benefit are all fine.
