Description

A device for switching intermediate melt flow direction in continuous smelting process

technical field

The utility model relates to the field of nonferrous metallurgy, in particular to a device for switching intermediate melt flows in a continuous smelting process.

Background technique

At present, in the continuous smelting process, the diversion of the intermediate melt flow between the primary smelting furnace and the sub-furnaces of the secondary refining is time-consuming and labor-intensive, serious flue gas pollution, poor heat preservation effect and many other new working conditions. According to the poor implementation of the live observation function, there are mainly the following deficiencies:

(1) It is difficult to control the water content of the mud used for artificial plugging and diversion (too high water content leads to blasting of copper liquid, which is a dangerous working condition; too low water content leads to low plasticity of the mud and is easy to be washed away), which leads to long time-consuming diversion and production low efficiency.

(2) When diverting to remove mud and dredging, the hot agglomerated mud is easily washed away by the melt, resulting in blockage of the feed port of the downstream secondary refining furnace, which is likely to cause secondary labor and affect normal production.

(3) Since the working stations are located between the furnaces, and the natural gas musket blowing flame and thermal insulation seal of the original plan is poor, the ambient temperature of the working condition is high, which is not suitable for workers to work for a long time. It is harmful to the health of workers, and the labor cost of the multi-person alternate rotation operation mode is high.

Contents of the invention

The purpose of the utility model is to provide a melt flow switching device in the middle of a continuous smelting process in order to solve the deficiencies of the prior art.

The new technical solution of the utility model is: a continuous smelting process intermediate melt flow switching device, including a swing tank, a branch chute, a primary melting furnace, and a refining furnace. The swing tank is divided into a swing tank main part and a swing tank side ear. The inner cavity of the main body of the swing tank is connected to the inner cavity of the side ears of the two swing tanks; the branch chute is divided into No. 1 branch chute and No. 2 branch chute, and one end of the No. 1 branch chute and No. 2 branch chute is respectively fixed by bolts On the side ear of the swing tank, and placed under the side ear of the swing tank to accept the melt, the other ends of the No. 1 branch chute and the No. 2 branch chute are respectively connected to the No. 1 secondary refining furnace and the No. 2 secondary refining furnace. There is also a copper spout on the top.

The swing groove can swing at any angle.

The copper outlet nozzle is welded on the copper outlet of the primary smelting furnace.

The side lugs of the pendulum groove are upturned.

The beneficial effects of the utility model are: the device is ingeniously designed, the components are relatively simple in action, more suitable for harsh working conditions, high in operation stability, long in service life, and easy to maintain; The work purpose requires that the melt diversion time is greatly shortened and manpower hours are reduced; the chute insulation cover has a good sealing effect, and the natural gas consumption is reduced by 30% compared with the previous scheme while ensuring the inner cavity temperature, reducing the emission of flue gas.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

A device for switching the flow direction of melt in the middle of a continuous smelting process, comprising a swing tank 1, a branch chute 2, a primary smelting furnace 3, and a refining furnace 4. The swing tank 1 is divided into a swing tank main body 5 and a swing tank side ear 6. The inner cavity of the groove main body 5 is connected to the inner cavity of the side ears 6 of the two pendulum grooves; the branch chute 2 is divided into the No. 1 branch chute 7 and the No. 2 branch chute 8, and the No. 1 branch chute 7 and the No. 2 branch chute 8 One end is respectively fixed on the side ear 6 of the swing tank by bolts, and placed under the side ear 6 of the swing tank to receive the melt. The other ends of No. 1 branch chute 7 and No. 2 branch chute 8 are respectively connected to No. 1 secondary refining furnace 9 and No. 2 secondary refining furnace The refining furnace 10 is also provided with a copper sprue on the primary smelting furnace 3 .

The swing tank 1 can swing at any angle.

The copper outlet nozzle is welded on the copper outlet of the primary smelting furnace 3 .

The side lugs 6 of the swing groove are upturned.

The swing tank 1 can swing at any angle from left to right. When the No. 1 secondary refining furnace 9 is fed, the motor drives the swing tank 1 to rotate so that the side ear 6 of the swing tank is connected to the No. 2 branch chute 8. At this time, the other swing tank The material outlet of the side ear 6 leaves the No. 1 branch chute 7, and the melt flows into the No. 2 branch chute 8 to complete the diversion of the melt flow, and work alternately in sequence.
