DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0026] In order to achieve the above-mentioned invention object, the utility model provides a conveying device for putting molten copper into a heat preservation furnace, such as Figure 1-Figure 6 As shown, including:

[0027] A furnace 1, wherein the furnace 1 is provided with a blower 12 and an air delivery pipe 13, wherein the input end of the blower 12 is connected to the furnace 1, and the output end of the blower 12 is connected to the air delivery pipe 13, wherein the air delivery pipe 13 is transversely provided with a plurality of insulation pipes 131;

[0028] The primary delivery pipe 2 has one end connected to the furnace 1, the output end of part of the insulation pipe 131 passes through the top wall of the primary delivery pipe 2, and part of the insulation pipe 131 is connected to the inside of the primary delivery pipe 2. A heater 21 is provided in the bottom wall of the primary delivery pipe 2, and a slag trough is provided at the other end of the primary delivery pipe 2;

[0029] One end of the secondary conveying pipe 3 is connected to the slag skimmer, part of the output end of the insulation pipe 131 passes through the top pipe wall of the secondary conveying pipe 3, and part of the insulation pipe 131 is connected to the inside of the secondary conveying pipe 3. The secondary conveying pipe 3 is provided with a motor 31, and a stirring rod 311 is provided at the output end of the motor 31. The stirring rod 311 passes through the side wall of the secondary conveying pipe 3 horizontally, and a stirring blade 312 is provided at the top of the stirring rod 311.

[0030] In this embodiment, when the molten copper is transferred, the heater 21 and the blower 12 are started, and the heater 21 cooperates with the blower 12 to heat and keep the primary conveying pipe 2 and the secondary conveying pipe 3 warm. Then, the molten copper to be transferred comes out of the melting furnace 1 and enters the primary conveying pipe 2. When the molten copper flows through the slag skimming trough, the staff can clean the scum in the molten copper to improve the quality of the molten copper. The motor 31 is started, and the motor 31 drives the stirring rod 311 to rotate. The stirring rod 311 is installed with stirring blades 312 in the secondary conveying pipe 3. The stirring blades 312 stir the molten copper. On the one hand, the flow rate of the molten copper can be accelerated, and on the other hand, the air inside the molten copper can be squeezed out to slow down oxidation.

[0031] In an optional implementation, the slag trough is U-shaped, and slag notches are transversely provided at both ends of the U-shaped slag trough, and the slag notches are C-shaped. In this embodiment, by utilizing the U-shaped design of the slag trough and the C-shaped slag notches, when the molten copper enters the slag trough, the space becomes larger and the flow rate slows down, and the staff can scrape the slag to the C-shaped slag notches. At the C-shaped slag notches, the flow rate of the molten copper is slow, and the staff can quickly and conveniently pick up the slag.

[0032] An optional embodiment further includes a heat preservation furnace 4, and the other end of the secondary conveying pipe 3 is connected to the heat preservation furnace 4. A support seat 41 is transversely provided on the outer side wall of the heat preservation furnace 4, and the base of the motor 31 is fixedly connected to the support seat 41. The stirring rod 311 rotates from the heat preservation furnace 4 to the melting furnace 1. The secondary conveying pipe 3 is also provided with an exhaust pipe 32, which is opened at the top of the secondary conveying pipe 3 and is located between the stirring blade 312 and the heat preservation furnace 4.

[0033] In this embodiment, the motor 31 is designed near the outer side of the secondary conveying pipe 3, and the output end of the motor 31 is connected to the stirring rod 311. When the motor 31 is started, the stirring rod 311 is driven to rotate. By designing the rotation direction and coordinating the flow direction of the molten copper, the stirring blade 312 can accelerate the flow rate of the molten copper in the secondary conveying pipe 3 to prevent the molten copper from being cooled due to long retention time. The internal gas of the molten copper after stirring can be discharged by the exhaust pipe 32 before entering the insulation furnace 4.
