[0007] Preferably, a second filter layer is fixedly connected to the inner wall of the processing chamber away from the bottom of the first filter layer, and a hole is opened on the outer wall of the processing chamber between the first filter layer and the second filter layer. The second filter layer filters heavy metal dust in the exhaust gas. The second filter layer is arranged in an arc shape. In the process of blowing out air from the air outlet, part of the water flow will be driven to impact the second filter layer. The heavy metal dust filtered by the second filter layer will accumulate at the bottom of the second filter layer, and the dust will fall down under the flushing of the water flow. The impact of the water flow is used to reduce the accumulation of dust at the bottom of the second filter layer, thereby ensuring that the second filter layer continues to filter the exhaust gas.

[0012] The present invention provides a waste gas recovery and treatment device for electrolytic copper production. It has the following beneficial effects: 1. The waste gas recovery and treatment device for electrolytic copper production uses a fan to suck the waste gas from the waste gas outlet and transport it to the treatment chamber. The outlet carries the waste gas and blows it into the treatment chamber. The water in the treatment chamber first cools the waste gas to avoid the high temperature affecting the operation of other electronic devices and prolonging the service life of other electronic devices. The water in the treatment chamber will filter the heavy metal dust in the waste gas, and the dust is intercepted by water to ensure the filtering effect of the waste gas.

[0013] 2. The waste gas recovery and treatment device for electrolytic copper production filters heavy metal dust in the waste gas through the second filter layer.

[0014] 3. The waste gas recovery and treatment device for electrolytic copper production, through the outlet, sprays water to impact the bottom of the placement plate, and cooperates with the water in the treatment chamber to increase the temperature of the waste gas during cooling. Therefore, when the water flow flushes the fixing agent, the fixing agent is melted and drips into the water in the treatment chamber, ensuring the treatment of harmful substances and thus ensuring the treatment effect of the waste gas.

[0015] 4. The waste gas recovery and treatment device for electrolytic copper production filters heavy metal dust in the water flow through the filter plate, so the heavy metal dust is intercepted in the water pressure chamber, and the remaining water is discharged into the treatment chamber again, avoiding excessive dust in the water in the treatment chamber and ensuring the filtering effect of the treatment chamber on the waste gas. When the filter plate descends, it will guide the dust accumulated at the bottom of the filter plate to descend, and when the circular plate descends, it will squeeze the ring plate to follow the decline. At this time, the circular plate and the pressure plate will be squeezed onto the pressure plate when they descend. The clamping of the two makes the dust accumulate together, and the lumps of dust will sink and then remain in the water pressure chamber, which guides the dust and reduces the accumulation of dust.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] For example, see Figure 1-5 The present invention provides a technical solution: a waste gas recovery and treatment device for electrolytic copper production, comprising a frame 1, an electrolytic copper electrolysis device 2 is fixedly connected to the inner wall of the frame 1, a waste gas outlet 4 is fixedly connected to the top of the electrolytic copper electrolysis device 2, an outer wall of the waste gas outlet 4 is fixedly connected to the top of the frame 1, an outer wall of the electrolytic copper electrolysis device 2 is fixedly connected to a solenoid valve outlet 3, a filter screen 5 is fixedly connected to the inner wall of the waste gas outlet 4, and a recovery mechanism 6 is fixedly connected to the top of the waste gas outlet 4; The recycling mechanism 6 includes: A suction bin 61, the suction bin 61 is fixedly connected to the top of the exhaust port 4; A connecting pipe 62, one end of which is fixedly connected to the outer wall of the suction bin 61, and the other end of which is fixedly connected to a fan 63; The connecting chamber 64 , the other end of the fan 63 is fixedly connected to the outer wall of the connecting chamber 64 .

[0021] The top of the connecting chamber 64 is fixedly connected with an air outlet 65 , the outer wall of the frame 1 is fixedly connected with a processing chamber 66 , and the top of the air outlet 65 is plugged into the bottom of the processing chamber 66 .

[0022] When in use, an appropriate amount of electrolytic copper is added to the electrolytic copper electrolysis device 2 through the solenoid valve outlet 3, and then the electrolysis procedure is carried out. The exhaust gas in the electrolysis process will rise to the exhaust port 4, and the fan 63 is powered on and started to be connected to the suction bin 61 through the connecting pipe 62, and then the exhaust gas in the exhaust port 4 is sucked, and then the fan 63 is transported to the processing bin 66 through the air outlet 65 on the connecting bin 64. An appropriate amount of water is put in the processing bin 66 in advance, and the air outlet 65 carries the exhaust gas to the processing bin 66. The water in the processing bin 66 first cools the exhaust gas, and then the water in the processing bin 66 filters the heavy metal dust in the exhaust gas.

[0023] For example 2, please refer to Figure 1-6 Based on the first embodiment, the present invention provides a technical solution: The outer wall of the processing chamber 66 is fixedly connected with a processing mechanism 7 . The processing mechanism 7 includes a first filter layer 71 . The first filter layer 71 is fixedly connected to the inner wall of the processing chamber 66 .

[0024] The second filter layer 72 is fixedly connected to the bottom of the inner wall of the processing chamber 66 away from the first filter layer 71 , and a hole is opened on the outer wall of the processing chamber 66 between the first filter layer 71 and the second filter layer 72 .

[0025] A first sealant 73 is fixedly connected to the outer wall of the processing chamber 66 at the position of the hole, and a placement plate 74 is inserted into the hole of the processing chamber 66 .

[0026] The outer wall of the placement plate 74 is fixedly connected with a second sealant 75 , and the outer wall of the placement plate 74 is provided with a leakage hole 76 .

[0027] When in use, the exhaust gas flows toward the top of the processing chamber 66, and the airflow will be filtered through the second filter layer 72, thereby filtering the heavy metal dust in the exhaust gas. The second filter layer 72 is arranged in an arc shape, and the air outlet 65 is arranged at the arc position of the second filter layer 72. Therefore, when the air outlet 65 blows out the airflow, part of the water flow will be driven to impact the second filter layer 72. The heavy metal dust filtered by the second filter layer 72 will accumulate at the bottom of the second filter layer 72, and the dust will fall down under the flushing of the water flow. Combined with Figure 5 As shown, the placement plate 74 is inserted into the hole of the processing chamber 66, and the hole is located between the first filter layer 71 and the second filter layer 72. A proper amount of solid adsorbent is placed in the multiple grooves on the placement plate 74 in advance, and then the water flow sprayed from the air outlet 65 hits the bottom of the placement plate 74, and then flows through the leakage hole 76 to the solid fixative in the placement plate 74. The water in the processing chamber 66 will increase the temperature of the exhaust gas during the cooling process, so when the water flow flushes the fixative, the fixative is melted and drips into the water in the processing chamber 66. The water mixed with the fixative treats the harmful substances. The use of solid fixative can delay the falling of the fixative, thereby extending the use time of the fixative. After the fixing agent in the placement plate 74 is used up, the placement plate 74 can be pulled out and solid fixing agent can be added again. When the placement plate 74 is inserted into the hole of the processing chamber 66, the second sealant 75 fits with the first sealant 73 to prevent airflow from being discharged.

[0028] For example 3, please refer to Figure 1-8 Based on the first and second embodiments, the present invention provides a technical solution: The bottom of the processing chamber 66 is fixedly connected to an auxiliary mechanism 8, which includes a water pump 81, the bottom of which is plugged into the water pump 81, and the outer wall of the frame 1 is fixedly connected to a hydraulic chamber 82, the bottom of which is plugged into the hydraulic chamber 82.

[0029] The top of the hydraulic bin 82 is fixedly connected to the guide tube 83, and the guide tube 83 is inserted into the bottom of the processing bin 66. The outer wall of the frame 1 is fixedly connected to a telescopic machine 87, and the top of the telescopic machine 87 is movably connected to a telescopic rod 84, and the telescopic rod 84 is inserted into the bottom of the hydraulic bin 82. The top of the telescopic rod 84 is fixedly connected to a filter plate 85, and the outer wall of the telescopic rod 84 is fixedly connected to a circular plate 89. The outer wall of the circular plate 89 is provided with a hole, and a limiting column 810 is inserted into the hole of the circular plate 89. The bottom of the limiting column 810 is fixedly connected to a ring plate 88, and the inner wall of the hydraulic bin 82 is fixedly connected to a pressure plate 86 at the bottom of the ring plate 88.

[0030] When in use, the water pump 81 is powered on and started during the exhaust gas filtering process. The water pump 81 sucks the water at the bottom of the processing chamber 66, and then discharges the water into the processing chamber 66 again through the connection between the hydraulic chamber 82 and the guide pipe 83. The guide pipe 83 blows the water flow toward the water pump 81, and the air outlet 65 is also arranged on the right side, so that the heavy metal dust sinking to the bottom of the water can be guided to flow toward the water pump 81. Combined with Figure 7 and 8 As shown, when the water flows through the hydraulic chamber 82, the filter plate 85 filters the heavy metal dust in the water flow, so the heavy metal dust is intercepted in the hydraulic chamber 82, and the remaining water is discharged into the processing chamber 66 again. The telescopic machine 87 is powered on to start and drive the telescopic rod 84 to move telescopically, which drives the filter plate 85 to descend and guides the dust accumulated at the bottom of the filter plate 85 to descend, and then the circular plate 89 will squeeze the annular plate 88 to follow the decline, and at this time, the circular plate 89 and the pressure plate 86 will be squeezed onto the pressure plate 86 when they descend, and the clamping of the two causes the dust to accumulate together, and the lumps of dust will sink and then remain in the hydraulic chamber 82. A door panel is set on the outside of the hydraulic chamber 82, and the remaining dust can be taken out after opening.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
