Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and
It is not used in the restriction present invention.
House refuse includes various garbage, such as pit, peel, rotten vegetable leaf, plastic bottle, old newsprint, packing box, ferrum
Nail, cap nut etc..For making full use of resource, typically before rubbish enters refuse depot, the available garbage in rubbish the most by
Reclaim and utilizing, but the less metal waste being entrained in rubbish is difficult to be found and reclaim.In order to preferably reclaim
Utilizing the ferromagnetism garbage in rubbish, the present invention devises a kind of screening rubbish device as shown in Figure 1, including housing 13,
Described housing 13 is provided above hopper 1, housing 13 one side is provided with ventilation duct 14, is provided with blower fan in ventilation duct 14
15, it is provided with along the axial arranged multiple outlets of ventilation duct 14 below housing 13, export 10 including the first outlet 11, second,
3rd outlet 9, described first outlet the 11, second outlet the 10, the 3rd outlet 9 sets to housing 13 opposite side successively from ventilation duct 14
Put.Export 11 and second described first and export 10, between the second outlet 10 and the 3rd outlet 9, be provided with dividing plate 12.Blower fan 15
Air blast in housing 13, the rubbish fallen from the blanking port 16 of hopper 1 is blown to four winds, the rubbish of different densities fall time
Resistance is different, and as pit, fragment of brick, stone fall very fast, that is blown is close together, and plastic bag, newspaper whereabouts resistance are relatively big, are blown
Obtain farther out, therefore can by different sieving garbages out.Falling from different outlets, pit, fragment of brick, stone etc. are near blanking
Out, newspaper, plastic bag are from the 3rd outlet 9 out, marginal from the second outlet for the first outlet 11 below mouth 16
10 out.Consequently facilitating sifting sort, carry out as required reclaiming or abandoning burying.
For filtering out the metal object in garbage, as it is shown in figure 1, be provided with metal screening device, institute in described housing 13
State metal screening device and include conveyer belt 3, electric magnet 4.
Metal screening device is arranged between housing 13 and hopper 1, as shown in Figure 1, Figure 2, above hopper 1 with housing 13
Being provided with opening 5, described conveyer belt 3 is arranged at opening 5, and described conveyer belt 3 includes three cylinders, the respectively first cylinder
201, second tin roller the 202, the 3rd cylinder 203, triangle between three cylinders, three cylinder positioning conveyors 3 also drive
Conveyer belt 3 operates, and conveyer belt 3 rotates from hopper 1 side down over;First cylinder 201 is positioned at hopper with second tin roller 202
1 opening part, second tin roller 202 and the 3rd cylinder 203 are positioned at the opening part on housing 13, and the 3rd cylinder 203 is positioned at housing 13
Outside;When conveyer belt 3 cycle operation, the metal object in the rubbish that will fall in rubbish from hopper 1 adsorbs, then from
Transport inside housing 13.
When conveyer belt 3 operates and passes through electric magnet 4 adsorbing metal thing, need to gather up the metal object adsorbed
Come, in order to reclaim.Need to control electric magnet 4 to be energized operation interval for this.Adsorbing metal thing when electric magnet 4 is energized, during power-off
Release metal object.As in figure 2 it is shown, be provided with pair of conductive contact 401 on electric magnet 4, at the first cylinder 201 and the 3rd cylinder
Being provided with conductive trough 18, conductive trough 18 approach second tin roller 202 between 203, described conductive trough 18 be arranged in parallel with conveyer belt 3,
Conductive trough 18 be arranged in hopper 1 with in housing 13, thus for energising shape time inside electric magnet 4 approach hopper 1 and housing 13
State, it is ensured that electric magnet 4 adsorbing metal thing in this interval.
It is energized and power-off, as it is shown on figure 3, be provided with two on conductive trough 18 to connect electricity respectively for convenience of controlling electric magnet 4
The bus 1801 that source connects, the conductive contact blade 401 on electric magnet 4 contacts with bus 1801;At electric magnet 4 along with conveyer belt
During 3 operating, get final product energizing magnetic when moving to hopper 1 upper conductive groove 18, it is achieved adsorbing metal thing, conductive contact blade
401 contact with conductive trough 18 always, and metal object keeps adsorbed state.Until conductive contact blade 401 goes out in housing 13 with electric magnet 4
When coming, conductive contact blade 491 separates with conductive trough 18, loses magnetism after electric magnet 4 power-off, and metal object drops to the collecting box of lower section
In 7.Circulate work and so forth.
After rubbish pours into hopper 1, owing to rubbish is squeezed in transit, and owing to rubbish containing water
Point, easily harden together, thus electric magnet 4 is difficult to sieve out by metal object.In order to improve screening effect, reduce metal object
Leakage sieve, is provided with agitation oar 17 in hopper 1, and described agitation oar 17 is positioned at above the blanking port 16 of hopper 1.Pour rubbish into
After, agitation oar 17 stirs rubbish so that it is loose off, consequently facilitating screening, adsorbing metal thing.
Blower fan 15 from ventilation duct 14 air blast time, for preferably ensureing that wind advertises direction flowing along blower fan 15, such as Fig. 1 institute
Showing, being provided with ventilated net 6 on described housing 13, described ventilated net 6 is arranged on the side relative with ventilation duct 14, is arranged such
Wind can be made as far as possible linearly to flow, plastic bag, newspaper etc. are taken to the 3rd outlet 9.
Smooth and easy in order to ensure rubbish blanking, simultaneously in order to ensure adsorbable go out metal object in rubbish, to conveyer belt 3 under
Incline direction in hopper 1 requires, and conveyer belt 3 is 30 ° with the angle of vertical direction in hopper 1.
For saving the space of screening rubbish device, reduce its volume, described hopper 1, ventilation duct 14 are arranged on housing
Same one end of 13, such that it is able to shorten the housing 13 length along ventilation duct 14 direction on the premise of ensureing screening effect.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any amendment, equivalent and the improvement etc. made within god and principle, should be included within the scope of the present invention.
