Description

Technical Field

[0001] This utility model provides a high-efficiency dust collection device for pyrometallurgical lead smelting, belonging to the technical field of auxiliary equipment for lead smelting. Background Technology

[0002] In the pyrometallurgical lead smelting process, the generation of dust-laden flue gas mainly originates from multiple stages. During the ore roasting stage, high-temperature roasting is required to oxidize and decompose the sulfides in the lead ore, generating large amounts of dust and flue gas containing harmful substances such as lead and sulfur. This dust-laden flue gas contains significant amounts of lead and its compounds, sulfur dioxide, particulate matter, and other harmful substances. Direct emission into the atmosphere would cause serious harm to the environment and human health. Therefore, dust collection and subsequent treatment of the flue gas are necessary.

[0003] When collecting dust from flue gas, filter modules with screens are typically used. These screens are enclosed within the filter module to prevent harmful gases from escaping. However, after a period of time, the screens often need to be replaced. Replacing the screen usually requires manually disassembling the filter module, replacing the screen, and then resealing the module. This process is often manual, cumbersome, and time-consuming, hindering efficient dust collection in pyrometallurgical lead smelting. To address these issues, a high-efficiency dust collection device for pyrometallurgical lead smelting is needed that can completely replace manual operation and efficiently replace the screens, thereby improving dust collection efficiency. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] according to Figure 1-4 As shown: This utility model provides a high-efficiency dust collection device for pyrometallurgical lead smelting: including a smelting furnace 1 and a dust collection component. The dust collection component is connected to the smelting furnace 1 through an exhaust pipe 2 with a valve, and an outlet pipe 5 is connected to the dust collection component.

[0022] The dust collection assembly includes two interconnected dust collection boxes 3. A fixed box 4 is fixedly connected to one side of the smelting furnace 1, and the two dust collection boxes 3 are slidably disposed below the fixed box 4. An adjusting component capable of driving the two dust collection boxes 3 to slide is installed inside the fixed box 4. Figure 3 As shown, the adjustment assembly includes an adjustment motor 7, a bidirectional lead screw 8, and a slider 9. The adjustment motor 7 is mounted on a fixed housing 4, and the bidirectional lead screw 8 is rotatably mounted inside the fixed housing 4 and fixedly connected to the output shaft of the adjustment motor 7. Two sliders 9 are provided, and the two sliders 9 are threadedly connected to corresponding positions of the bidirectional lead screw 8. A guide groove 6 is provided at the bottom of the fixed housing 4, and the two sliders 9 pass through the guide groove 6 and are fixedly connected to the two dust collection boxes 3 respectively. By setting the bidirectional lead screw 8 and sliders 9, the sliding splicing control of the two dust collection boxes 3 can be easily achieved.

[0023] The exhaust pipe 2 and the outlet pipe 5 are flexible hoses, ensuring a normal connection between the dust collection box 3 and the exhaust pipe 2 and outlet pipe 5 even when the two dust collection boxes 3 are sliding. Furthermore, a sealing gasket is installed at the joint of the two dust collection boxes 3 to ensure a tight seal. Also includes:

[0024] Rotary replacement assembly and filter 10; the rotary replacement assembly is rotatably set below the dust collection box 3, and two filters 10 are fixedly connected to the rotary replacement assembly, with one of the filters 10 located at the position where the two dust collection boxes 3 are spliced ​​together.

[0025] like Figure 3As shown, the rotating replacement assembly includes a rotating shaft 11 and a connecting rod 13. The rotating shaft 11 is rotatably positioned below the dust collection box 3, and the connecting rod 13 is fixedly connected to the rotating shaft 11, with the filter screen 10 also fixedly connected to the connecting rod 13. A rotating motor 12 is fixedly installed on the outer wall of the smelting furnace 1, and the rotating shaft 11 is fixedly connected to the output shaft of the rotating motor 12, allowing for convenient rotation control of the rotating shaft 11. Two connecting rods 13 are provided, corresponding to the filter screens 10, and the two filter screens 10 are positioned 180° apart. When the rotating shaft 11 is rotated by the rotating motor 12, the positions of the two filter screens 10 can be quickly changed, thus completing the removal of the old filter screen 10 and the installation of the new filter screen 10 in a very short time.

[0026] like Figure 2 As shown, a receiving box 14 is provided on one side of the smelting furnace 1, located directly below the filter screen 10; when the replaced filter screen 10 is directly cleaned by external cleaning equipment, the wastewater can be collected using the receiving box 14.

[0027] The principle of this utility model

[0028] like Figure 1 , 2 The diagram shows the normal operating state of the dust collection equipment provided in this application. At this time, the flue gas in the smelting furnace 1 can enter the two dust collection boxes 3 through the exhaust pipe 2. After being filtered by the filter screen 10 in the dust collection box 3, it is finally discharged from the outlet pipe 5 to enter the next processing step.

[0029] When filter 10 needs to be replaced, such as Figure 3 , 4 As shown, first, close the valve on exhaust pipe 2 to pause the flue gas discharge process; start the regulating motor 7, and driven by the slider 9, the two dust collection boxes 3 move away from each other, thus opening the dust collection boxes 3. Then, start the rotating motor 12 to drive the rotating shaft 11 to rotate, causing the two filter screens 10 to exchange positions, thus quickly completing the replacement of the filter screens 10. Reverse the regulating motor 7 to drive the two dust collection boxes 3 to reassemble, so that the newly replaced filter screens 10 are firmly held in the dust collection box 3. At this time, the valve can be opened immediately to continue the dust collection work. As for the replaced filter screens 10, they can be washed using external cleaning equipment, and the receiving box 14 can collect the washing wastewater.
