Description

TECHNICAL FIELD

[0002] The statements in this section merely provide background information related to the technical solutions of the present application to help understand the present application and do not necessarily constitute the prior art for the technical solutions of the present application.

[0003] The feeding mode in metallurgical furnace is various, when the furnace door direction is vertical, the material is generally stably calcined by natural sedimentation, or the material is once put into the furnace for calcination; when the furnace door direction is horizontal, the material is generally fed by one-time feeding. For the feeding mode when the furnace door is vertical, the environmental protection is poor, and dust and smoke overflow easily during feeding, which not only leads to the deterioration of the working environment, but also is harmful to the health of the workers. For the one-time feeding mode when the furnace door is horizontal, the material is generally accumulated, which causes a large temperature difference between the inside and the surface of the material, and is not conducive to the full pyrolysis of the material. Blindly increasing the fuel delivery amount will cause energy waste and valuable metal loss. SUMMARY

[0004] In view of the shortcomings of the above two feeding and pyrolysis modes in metallurgical furnace, the present application improves the material feeding mode and pyrolysis method without changing the direction of the furnace door, adopts a three-dimensional layered stacking bracket, which has a good spatial network structure layout and can be reliably connected between layers without the risk of displacement or tilting. After the material is loaded into the tray and placed in the gap of the layered bracket, all the tools are assembled and placed stably in the furnace by a forklift for preliminary material pyrolysis. Fuel lances are installed at multiple positions on the metallurgical furnace shell, and when the material is pyrolyzed, different positions of the fuel lances are used to spray and burn the material at different positions of the bracket, which can uniformly pyrolyze the material in the tray. The layered layout of the bracket and the tray can greatly reduce the problem of ash scattering, and weaken the disadvantage of insufficient pyrolysis of accumulated material, which has the advantages of ensuring environmental protection in the working area and improving the recovery rate of valuable metals.

[0021] The tray comprises a tray main body 6 and two tray grabbing ears 5 located at both sides of the tray main body 6.

[0022] When the plurality of supporting beams are stacked together, the four lower supporting legs 2 of the upper supporting beam located at the lower four corners of the anti-displacement supporting beam 4 can be clamped in the four anti-displacement upper clamping legs 1 of the lower supporting beam adjacent thereto, so as to ensure that the plurality of stacked supporting beams will not move relatively.

[0023] The charging tool of the present application is used in actual application, through embedding assembly of the lower support 2 of the adjacent bracket and the anti-displacement upper clamping foot 1, the plurality of brackets are stacked into layers in turn, and finally the bracket and the tray placed on the bracket are put into the pyrolysis furnace by the electric forklift to decompose the material, and the valuable precious metal is further extracted from the pyrolysis ash.
