Further, described conveyer belt is a wire netting conveyer belt.Be beneficial to conveyer belt and transfer heat to electron wastes placed on it.
Further, described hot air apparatus comprises air blast and heater, is arranged in hot air circulating pipe both it, and the air port of described air blast is facing to heater blowing.The wind of air blast blowout becomes hot blast after heater, enters in bellows, then from air outlet out, enters hot air circulating pipe and get back to air blast, realize recycling of hot blast through hot air circulating pipe to from air inlet.
Further, described recycling of WEEE device also comprises an air curtain, and described recycling of WEEE device also comprises an air curtain, and this air curtain is arranged on the top of the opposite end opening of described hot box, and facing to below blowing.Cut off hot box by this air curtain flow with extraneous air, prevent the lost of heat in hot box.
Further, described recycling of WEEE device also comprises one makes hot box and the extraneous air curtain curtain cut off, and this air curtain curtain is arranged on the edge of the opposite end opening of described hot box.Prevent scattering and disappearing of heat in hot box.
Further, described recycling of WEEE device also comprises a heat insulation foam, and the outer surface of described hot box and hot air circulating pipe or interlayer are covered with this heat insulation foam.Play heat insulation and insulation effect.
In order to understand better and implement, describe the present invention in detail below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the perspective view of the side of recycling of WEEE device of the present invention.
Fig. 2 is the perspective view in the device of recycling of WEEE shown in Fig. 1 front.
Detailed description of the invention
Please refer to the perspective view that Fig. 1 and Fig. 2, Fig. 1 are recycling of WEEE device sides of the present invention, Fig. 2 is the perspective view in the device of recycling of WEEE shown in Fig. 1 front.This recycling of WEEE device comprises support 1, hot box 2, connecting gear 3, hot air circulating pipe 4 and hot air apparatus 5.Described hot box 2 is arranged on support 1, and described hot box 2 two ends are provided with opening, and described connecting gear 3 to be arranged on support 1 and to run through this hot box 2 by this opening.Described hot box 2 is provided with air inlet 21 and air outlet 22, and this air inlet 21 and air outlet 22 can be separately positioned on two ends up and down or the two ends relatively far apart of hot box 2.Described hot air circulating pipe 4 is connected with air outlet 22 with described air inlet 21, and described hot air apparatus 5 to be arranged in hot air circulating pipe 4 and to produce hot blast.The hot blast that described hot air apparatus 5 blows out enters into hot box 2 through hot air circulating pipe 4 from air inlet 21, and acts on the electron wastes being arranged on the connecting gear 3 running through hot box 2, then gets back to hot air apparatus 5 from air outlet 22 through hot air circulating pipe 4.
Particularly, described connecting gear 3 comprises motor 31, roller bearing 32 and conveyer belt 33.Described roller bearing 32 is arranged on described support 1, and described conveyer belt 33 to be laid on this roller bearing 32 and end to end in the bottom of support by running through hot box 2 opposite end opening.Described motor 31 is coaxially connected by gears meshing with this roller bearing 32.Drive roller bearing 32 to rotate by motor 31, roller bearing 32 drives conveyer belt 33 cycle operation on it.The speed that described motor 31 drives described conveyer belt 33 to move is adjustable, makes it match with the length of described conveyer belt 33.
Described hot air apparatus 5 comprises air blast 51 and heater 52, is arranged in hot air circulating pipe 4 both it, dries facing to heater 52 in the air port of described air blast 51.
Further, this recycling of WEEE device also comprises an air curtain 6, this air curtain 6 is arranged on the top of the opposite end opening of described hot box 2, and facing to below blowing, thus form an air curtain, cut off hot box 2 by this air curtain flow with extraneous air, prevent the lost of heat energy in hot box 2.Preferably, can also arrange an air curtain curtain, this air curtain curtain is arranged on described hot box 2 opposite end edge, and in further minimizing hot box 2, heat scatters and disappears.
Preferably, the recycling of WEEE device in the present embodiment also comprises a heat insulation foam (not shown), and outer surface or the interlayer of described hot box 2 and hot air circulating pipe 4 are covered with this heat insulation foam.Prevent the heat loss of hot blast, play heat insulation and insulation effect.
During use, the wind that air blast 51 blows out, after heat blower 52 becomes hot blast, is transported in hot box 2 by hot air circulating pipe 4 and air inlet 21, makes to be full of hot blast in hot box 2.Air blast 51 blows hot air circulation flowing simultaneously, ensures that the temperature in hot box 2 keeps not lowering the temperature.Electron wastes is placed on conveyer belt 33, along with conveyer belt 33 enters in hot box 2.Hot blast heats electron wastes in hot box 2.Along with the rising of temperature, therefore the plastic portions of electron wastes almost remains unchanged because thermal conductivity is poor, but the thermal conductivity of the metal object in electron wastes is very good, it is subject to the heating of hot blast and temperature rises rapidly, the temperature of metal object constantly raises and then makes the coated plastic portions of its periphery start expanded by heating and fusing when electron wastes passes hot box 2 with conveyer belt 33, and namely metallic member is easily extracted the object reaching separation by the instrument such as available pliers.
Compared to prior art, the present invention is directly heated electron wastes by hot blast, and be separated relative to poach, the efficiency of heating surface is high, more energy-conserving and environment-protective.Further, due to the metal object in electron wastes be rapidly heated after the plastic cement of its periphery can be made to expand and micro-molten, do not need the strength that expense is very large during separation, soon, efficiency is high, can carry out the recycling of discarded object in enormous quantities for separating rate.Simultaneously relative to the method for poach electron wastes, hot blast of the present invention can recycle in a device, greatly saves resource.
As to further optimization of the present invention, described air inlet 21 is arranged on bottom this hot box 2, and described air outlet 22 is arranged on this hot box 2 top, makes hot blast from the bottom of connecting gear 3 to blowing up.Like this, the hot blast that heater 52 produces can act on and the electron wastes on conveyer belt the very first time.In addition, this conveyer belt is metal mesh structure, is beneficial to its heat conduction.Meanwhile, the power of adjustable air blast 51 increases, and when the wind-force that it produces is enough large, can blows the electron wastes rolling on conveyer belt, make its homogeneous heating.Meanwhile, the conveyer belt of metal material can simultaneously stability hot blast heat and be increased to enough temperature to the swollen effect of the plastic cement produce heat-dissipating on it, thus improve the efficiency of itself and metal separation further.
The present invention does not limit to and above-mentioned embodiment, if do not depart from the spirit and scope of the present invention to various change of the present invention or distortion, if these are changed and distortion belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these changes and distortion.
