Problems solved by technology

[0003] At present, a smelting furnace is needed to recycle scrap copper, but there are still some deficiencies in the existing smelting furnace. Further heating, the copper water will continue to boil in the smelting furnace, and it will easily splash out of the smelting furnace, which is very dangerous. However, if the sealed method is used for smelting, the pressure in the smelting furnace will continue to rise, which is also very dangerous. Therefore, it is urgently needed Design a smelting furnace for scrap copper smelting and recycling to solve the above problems

Embodiment 1

[0028] refer to Figure 1-2 , a smelting furnace for smelting and recycling scrap copper, comprising a combustion chamber 1, a smelting furnace body 3 and a flame gun 4, the top outer wall of the combustion chamber 1 has an installation opening, and the smelting furnace body 3 is fixedly arranged in the installation opening, and the flame The gun 4 is fixedly arranged on the bottom inner wall of the combustion chamber 1, and the outer wall around the combustion chamber 1 is fixedly connected with a side plate 7, and the top outer wall of the side plate 7 is fixedly connected with a hydraulic cylinder 8, and one end of the piston of the hydraulic cylinder 8 is provided with a cover plate 9. The cover plate 9 is provided with a smoke exhaust mechanism, and the inside of the smelting furnace body 3 is provided with a splash prevention mechanism.

[0029] The anti-splash mechanism includes a splash-proof bucket 5 and a fixed cover 17. The splash-proof bucket 5 is fixedly arranged ...

Embodiment 2

[0037] refer to Figure 3-4 , a smelting furnace for smelting and recycling waste copper. Compared with Embodiment 1, this embodiment also includes a pressure relief port on one side of the outer wall of the combustion chamber 1, and a pressure relief cylinder is fixedly connected to the inner wall of the pressure relief port. 18. A spring 20 is fixedly connected to one side of the inner wall of the pressure relief cylinder 18, and a rubber plug 21 is fixedly connected to one end of the spring 20. The outer wall of the pressure relief cylinder 18 is provided with pressure relief holes 19 equidistant and circularly distributed.

[0038] Working principle: When the flame gun 4 heats the melting furnace body 3, the air in the combustion chamber 1 will be heated and the air pressure will increase. When the air pressure exceeds a certain value, the rubber plug 21 will be urged to compress the spring 20 in the pressure relief cylinder 18 , so that the rubber plug 21 is removed from ...

Abstract

The invention discloses a smelting furnace for waste copper smelting recovery. The smelting furnace comprises a combustion chamber, a smelting furnace body and a flame gun, wherein a mounting openingis formed in the outer wall of the top of the combustion chamber, and the smelting furnace body is fixedly arranged in the mounting opening; the flame gun is fixedly arranged on the inner wall of thebottom of the combustion chamber; side plates are fixedly connected to the outer walls of the periphery of the combustion chamber, and hydraulic cylinders are fixedly connected to the outer walls of the tops of the side plates; a cover plate is arranged at one end of a piston of each hydraulic cylinder, and a smoke exhaust mechanism is arranged on each cover plate; a splash-proof mechanism is arranged in the smelting furnace body and comprises a splash-proof hopper and a fixed cover; and the splash-proof hopper is fixedly arranged on the inner wall of the smelting furnace body, and dischargingholes which are annularly distributed at equal intervals are formed in the outer wall of the splash-proof hopper. According to the smelting furnace, molten copper is prevented from being splashed outof the smelting furnace, the safety performance of the smelting furnace in the using process is effectively improved, pollution of smoke dust to air is effectively avoided, and the requirements for energy conservation and environment protection are met.

Description

technical field [0001] The invention relates to the technical field of scrap copper recovery, in particular to a melting furnace for smelting and recycling scrap copper. Background technique [0002] With the rapid development of the national economy, on the one hand, copper consumption has increased rapidly and copper prices have soared, while my country's copper resources are in short supply, and the output of copper concentrates cannot meet the demand. On the other hand, waste household appliances and waste cables have also increased rapidly in recent years, causing environmental pollution. pollution, so the recycling of scrap copper is a shortcut for the rapid development of my country's copper industry to make up for the shortage of raw materials. For a long time, copper rod manufacturers in various countries have been trying to increase the proportion of scrap copper in raw materials. [0003] At present, a smelting furnace is needed to recycle scrap copper, but there a...
