Description

TECHNICAL FIELD

[0001] The utility model relates to the auxiliary equipment of anode plate casting, in particular to an anode copper casting flue gas collecting device. BACKGROUND

[0002] The anode copper plate for copper electrolysis is commonly known as an anode plate, which is formed by pouring copper melted in an anode furnace, that is, the anode plate forming die on the disc casting machine is arranged in a circular ring shape, the empty anode plate forming die reaches the pouring runner in turn, copper is poured into the die cavity of the anode plate forming die, and the die containing the copper liquid needs to be sprayed and cooled after moving away from the pouring runner so as to solidify as soon as possible, the initially solidified anode plate is lifted by the lifting mechanism at the plate lifting station and is taken away from the anode plate forming die by the picking mechanism, so as to reach the pouring runner again to form the next anode plate.

[0003] In order to facilitate demolding, the die cavity of the anode plate forming die needs to be coated with barium sulfate as a demolding agent, at the spraying station, high-temperature water vapor carrying barium sulfate forms white water mist that disperses everywhere, which not only seriously affects the production environment but also causes great harm to the health of the on-site operators, and in addition to the strict limitation of environmental protection regulations, the simple scheme of setting a flue gas collection and exhaust system must also be rectified. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing an anode copper casting flue gas collecting device for treating the flue gas generated by the evaporation of the demolding agent in the casting process, intercepting barium sulfate in the flue gas, realizing low-cost treatment of the casting flue gas, and protecting the health of the on-site operators.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anode copper casting flue gas collecting device, comprising a first gas collecting hood, the first gas collecting hood is arranged downstream of the pouring runner and close to the pouring runner, the first gas collecting hood is connected with an exhaust pipe, the hood opening of the first gas collecting hood is suspended above the anode plate and the anode plate forming die, characterized in that: a filter screen is arranged at the downstream end of the exhaust pipe.

[0006] After the above-mentioned technical scheme is adopted, the anode copper casting flue gas is collected by the first gas collecting hood and is discharged through the exhaust pipe, the temperature of the high-temperature water vapor carrying barium sulfate in the form of white water mist gradually decreases, and the barium sulfate is condensed and solidified at the filter screen arranged at the downstream end of the exhaust pipe to be intercepted, and the relatively clean water vapor is freely discharged, avoiding the environmental pollution caused by the direct discharge of barium sulfate mist.

[0012] An anode copper casting smoke collecting device, comprising a first gas collecting cover 10, the first gas collecting cover 10 is arranged downstream of a casting runner and close to the casting runner, the first gas collecting cover 10 is communicated with a smoke exhaust pipeline 40, the cover opening of the first gas collecting cover 10 is suspended above the anode plate and an anode plate forming die A, characterized in that: a filter screen 41 is arranged at the downstream end of the smoke exhaust pipeline 40.

[0013] In the above scheme, the first gas collecting cover 10 is arranged at the working position section of the first spraying section A1, the first gas collecting cover 10 performs water cooling operation on the anode plate forming die, and absorbs the mixed gas of water vapor and barium sulfate particles evaporated by the high-temperature copper liquid.

[0014] After the above technical scheme, the anode copper casting smoke is collected by the first gas collecting cover and discharged through the smoke exhaust pipeline, the temperature of the high-temperature water vapor with white water mist carrying barium sulfate gradually decreases, and the barium sulfate is condensed and solidified at the filter screen arranged at the downstream end of the smoke exhaust pipeline to be intercepted, and the relatively clean water vapor is freely discharged, avoiding environmental pollution caused by direct discharge of barium sulfate mist.

[0015] The anode plate cooled by the first spraying section A1 has been preliminarily solidified, and then the anode plate can be taken away from the anode plate forming die A by the anode plate picking mechanism and placed in a cooling water tank for further cooling. In order to ensure that the anode plate forming die A is in a suitable temperature state to receive the copper liquid flowing from the casting runner, further cooling needs to be implemented on the anode plate forming die A before it reaches the casting position of the casting runner, that is, the second cooling is implemented in the second spraying section A2. The downstream of the first gas collecting cover 10 is provided with a second gas collecting cover 20, the second gas collecting cover 20 is correspondingly arranged at the working position section of the second spraying section A2, and the first gas collecting cover 10 and the second gas collecting cover 20 are respectively connected to the smoke exhaust pipeline 40 through the first branch pipe 11 and the second branch pipe 21.

[0016] The spraying operation of the second spraying section A2 still has barium sulfate release agent dispersed in the form of mist, and the second gas collecting cover 20 can effectively collect the dispersed barium sulfate release agent; the pipeline arrangement scheme that the first gas collecting cover 10 and the second gas collecting cover 20 are respectively connected to the smoke exhaust pipeline 40 through the first branch pipe 11 and the second branch pipe 21 can simplify the pipeline.

[0017] The exhaust fan 50 is arranged on the exhaust pipeline 40. The casting fume is transported to the outdoor exhaust outlet through the exhaust pipeline 40 by the exhaust fan 50.

[0018] As a preferred solution, the filter screen 41 is arranged in the range of 30 cm of the outlet of the exhaust pipeline 40, and 15 pieces of filter screens 41 are arranged at intervals. The filter screen 41 is woven by stainless steel wires with a diameter of 2 mm on a square screen frame, and the mesh size is 3 mm. The mesh hole here is a square hole with a side length of 3 mm. After being intercepted and filtered by the filter screen 41, the barium sulfate particles are retained, avoiding the direct discharge of barium sulfate to the environment.

[0019] Further, the junction of the straight section and the rising section of the exhaust pipeline 40 upstream of the filter screen 41 is provided with a material taking port, and the material taking port is provided with an opening and closing door. In this way, the retained barium sulfate solid can be conveniently taken out and cleaned. The material taking port is arranged at the junction of the straight section and the rising section of the exhaust pipeline 40 because the temperature and kinetic energy of the fume decrease during the rising process, causing the barium sulfate particles to settle at the junction. In addition, the filter screen 41 is arranged at the junction, and the filter screen 41 is assembled through the assembly window. When the filter screen 41 is replaced and cleaned, the intercepted barium sulfate at the junction is also cleaned.
