Description

Technical Field

[0001] This utility model relates to the field of silver smelting, specifically to a flue gas treatment device for silver smelting. Background Technology

[0002] The flue gas generated during silver smelting contains pollutants such as heavy metals, sulfides, and dust. It needs to be treated through multiple stages to meet emission standards. First, the flue gas needs to be pretreated to collect the flue gas generated by the smelting furnace and prevent it from escaping. In the pretreatment process, the flue gas is mainly collected by a gas collection hood.

[0003] Currently, when collecting flue gas using a gas collection hood, a large amount of dust adheres to the inner wall of the hood. This dust accumulation reduces the cross-sectional area of ​​the hood's inner cavity, thereby increasing airflow resistance and causing a decrease in local wind speed. Consequently, the flue gas collection efficiency is reduced. Furthermore, subsequent shutdown and cleaning of the dust also reduces the flue gas treatment efficiency. Therefore, a flue gas treatment device for silver smelting is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and avoid the problem of dust accumulation on the pipe wall of the gas collection hood leading to a reduction in flue gas treatment efficiency, this utility model proposes a flue gas treatment device for silver smelting.

[0028] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail as follows:

[0029] This application discloses a flue gas treatment device for silver smelting. (Refer to...) Figure 1 A flue gas treatment device for silver smelting, comprising:

[0030] Collection cover 1, with a lower connecting pipe 2 fixedly connected to the top of collection cover 1, and an upper connecting pipe 3 provided at the top of the lower connecting pipe 2;

[0031] Jet assembly 4 is located at the top inside the lower connecting pipe 2;

[0032] Cleaning component 5 is located inside jet assembly 4;

[0033] Reference Figures 2-3 The jet assembly 4 includes a hollow tube 41 that is snapped into the lower connecting pipe 2. A jet port 42 is provided at the bottom of the hollow tube 41. A nozzle 43 is fixedly connected to the bottom of the hollow tube 41 at the jet port 42. The jet ports 42 are evenly distributed at the bottom of the hollow tube 41. The nozzle 43 communicates with the interior of the hollow tube 41 through the jet port 42. The gas inside the hollow tube 41 is ejected through the jet port 42 and the nozzle 43, thereby cleaning the dust adhering to the interior of the lower connecting pipe 2. A connecting valve 44 is provided inside the nozzle 43. A connecting plate 45 is snapped into the bottom end of the nozzle 43. An inlet pipe 46 is fixedly connected to the rear end of the hollow tube 41. The inlet pipe 46 communicates with the interior of the hollow tube 41. The end of the inlet pipe 46 away from the hollow tube 41 extends through the lower connecting pipe 2 to the outside of the lower connecting pipe 2. The inlet pipe 46 is connected to an air pump. At this time, gas can be pumped into the interior of the hollow tube 41 by the air pump.

[0034] Reference Figures 3-5The cleaning component 5 includes two support plates 51 fixedly installed inside the hollow tube 41. A buffer pad 52 is fixedly connected to one end of the two support plates 51 that is far apart from each other. A hollow tube 531 is fixedly connected inside the two support plates 51. A bottom groove 532 is opened at the bottom of the hollow tube 531. A motor 541 is fixedly connected to the left end of the lower connecting tube 2. A drive rod 542 is fixedly connected to the output end on the right side of the motor 541. A connecting rod 543 is fixedly connected to the right end face of the drive rod 542. A through hole 1 that matches the drive rod 542 is opened on the surface of the hollow tube 41. The drive rod 542 extends through the through hole 1 into the interior of the hollow tube 41. A through hole 2 that matches the connecting rod 543 is opened on the surface of the hollow tube 531. The connecting rod 543 passes through the through hole 2 and through the hollow tube 531. The drive motor 541 can drive the drive rod 542 and the connecting rod 543 to rotate. A steel cable 544 is wound around the surface of the connecting rod 543.

[0035] Reference Figures 4-6 A fixing block 551 is fixedly connected to the middle of the right side inside the hollow tube 531. Two sliding sleeves 552 are slidably connected to the surface of the hollow tube 531. A connecting block 553 is fixedly connected inside the sliding sleeve 552. The end of the steel cable 544 away from the connecting rod 543 is fixedly connected to the surface of the connecting block 553. The connecting block 553 is slidably connected inside the hollow tube 531. When the connecting rod 543 rotates, it will wrap around the steel cable 544 and pull the connecting block 553 to slide inside the connecting rod 543. At this time, the connecting block 553 will drive the sliding sleeve 552 to slide, so that the sliding sleeve 552 drives the push block 554 to clean the inner wall of the hollow tube 41. The bottom end of the sliding sleeve 552 is fixedly connected to a push block 554. The buffer pad 52 and the push block 554 are adapted to each other and contact each other. The push block 554 is slidably connected to the bottom wall of the hollow tube 41. The buffer pad 52 can stop and buffer the sliding push block 554. The end of the connecting block 553 near the fixed block 551 is fixedly connected to a metal spiral rope 555. The combination of the connecting block 553, the push block 554 and the metal spiral rope 555 is symmetrically arranged on the right side of the hollow tube 531. The end of the metal spiral rope 555 away from the connecting block 553 is fixedly connected to the surface of the fixed block 551. The two push blocks 554 improve the cleaning efficiency of the inner wall of the hollow tube 41.

[0036] Working principle: The operator can connect the end of the inlet pipe 46 away from the hollow pipe 41 to the output end of the air pump. At this time, the air pump can be controlled to periodically spray gas. The gas will enter the interior of the hollow pipe 41 through the inlet pipe 46. Then, the gas inside the hollow pipe 41 will be sprayed out of the interior of the nozzle 43 through the jet nozzle 42. At this time, the gas will be sprayed down the inner wall of the lower connecting pipe 2 through the nozzle 43, thereby cleaning the dust on the inner wall of the lower connecting pipe 2 and preventing dust from accumulating on the inner wall of the lower connecting pipe 2 and affecting the capture of flue gas.

[0037] After the flue gas collection is completed, the end of the inlet pipe 46 away from the hollow tube 41 can be connected to the output end of the water pump. The water pump can then be driven to pump water into the interior of the hollow tube 41. Afterward, the motor 541 can be driven to rotate the drive rod 542 and the connecting rod 543. When the connecting rod 543 rotates, it will wind the steel cable 544. At this time, the steel cable 544 will pull the fixedly connected connecting block 553. The connecting block 553 is pulled to the left side of the hollow tube 531. At the same time, since the bottom of the connecting block 553 penetrates the inner wall of the bottom groove 532 and the sliding sleeve 552, the connecting block 553 is also pulled to the left side of the hollow tube 531. The connection is fixed, so the connecting block 553 will drive the sliding sleeve 552 to move accordingly. At this time, the sliding sleeve 552 will drive the fixedly connected push block 554 to move accordingly. At this time, the water flows inside the hollow tube 41, and the push block 554 slides inside the hollow tube 41. Therefore, the push block 554 and the water flow can clean the dust that enters the hollow tube 41, so that the dust is discharged through the air nozzle 42 with the water flow. At the same time, the water flow will also be sprayed through the spray pipe 43 to the inner wall of the lower connecting pipe 2, and then the water flow will further clean the dust on the inner wall of the lower connecting pipe 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
