Description

Technical Field

[0001] The utility model relates to the field of non-ferrous metal smelting, in particular to a fume extraction and dust removal device for non-ferrous metal smelting. Background Art

[0002] Non-ferrous metal smelting refers to the production process of separating associated elements from ores, concentrates, secondary resources or other materials to produce non-ferrous metals or their compounds. During the non-ferrous metal smelting process, a large amount of flue gas and dust need to be extracted. In addition to a large amount of nitrogen, sulfur dioxide and oxygen, the smelting flue gas also contains some solid and gaseous harmful substances. These harmful substances are directly discharged into the air, which will cause serious damage to the environment.

[0003] At present, in the process of non-ferrous metal smelting, waste gas is usually introduced into water to allow the water to absorb harmful substances and dust in the waste gas. However, after a long period of absorption, the water will become turbid and not conducive to the subsequent treatment of the waste gas. The mixture of water and harmful substances needs to be replaced frequently by humans, resulting in low waste gas treatment efficiency. In addition, the water fluidity in most waste gas treatment devices is poor, resulting in insufficient mixing of water and waste gas, which leads to insufficient treatment of the waste gas.

DETAILED DESCRIPTION

[0016] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, and bonding in the prior art, which will not be described in detail here.

[0017] Example 1: A fume extraction and dust removal device for non-ferrous metal smelting, such as Figure 1-Figure 4 As shown, it includes a box body 1, support legs 2, a one-way valve 3, an air inlet pipe 4, a stirring rod 5, a support frame 6, a servo motor 7, a water inlet pipe 8, a water outlet pipe 9, a limit plate 10, a sliding rod 11, a reset spring 12 and an air outlet pipe 13. The bottom of the box body 1 is connected to two support legs 2 by bolts. The two support legs 2 are symmetrically arranged. Both support legs 2 are H-shaped structures. The lower part of the box body 1 is fixedly connected to a one-way valve 3, and the one-way valve 3 is connected to an air inlet pipe 4 through a flange. The air inlet pipe 4 is connected to the box body 1. The middle part of the box body 1 is rotatably connected to a stirring rod 5, and a plurality of short rods are arranged on the stirring rod 5. The stirring rod 5 is horizontally arranged. One side of the box body 1 is A support frame 6 is connected with rivets, and a servo motor 7 is connected to the center of the support frame 6 by bolts. One end of the stirring rod 5 is fixedly connected to the output shaft of the servo motor 7. A water inlet pipe 8 is connected to the top of the box body 1 through a flange, and the water inlet pipe 8 is connected to the box body 1. A water outlet pipe 9 is fixedly connected to the bottom of the box body 1, and the water outlet pipe 9 is connected to the box body 1. Limiting plates 10 are welded to the top and bottom of the box body 1, and a sliding rod 11 is slidably connected between the two limiting plates 10. A reset spring 12 is connected between the two limiting plates 10 and the sliding rod 11 through a hook. An air outlet pipe 13 is connected to the top of the box body 1 through a flange, and the air outlet pipe 13 is connected to the box body 1.

[0018] Initially, the sliding rod 11 blocks the water inlet pipe 8 and the water outlet pipe 9. First, the box 1 is filled with water, and the exhaust gas enters the box 1 from the air inlet pipe 4. The exhaust gas passes through the one-way valve 3, so that the exhaust gas can only enter but not exit. The operator starts the servo motor 7, and the servo motor 7 drives the stirring rod 5 to rotate through the output shaft, so that the exhaust gas and water are evenly mixed and fully integrated, so that the water can fully absorb the harmful substances and dust in the exhaust gas, which is more conducive to the discharge of the exhaust gas. The treated exhaust gas is discharged through the water outlet pipe 9, and the dust will settle at the bottom of the box. When it is necessary to replace the water and harmful substances When a mixture of water and harmful substances is needed, the operator manually pulls the sliding rod 11, the sliding rod 11 moves outward, the reset spring 12 is compressed, the sliding rod 11 no longer blocks the water inlet pipe 8 and the water outlet pipe 9, and water enters the box body 1 from the water inlet pipe 8. At the same time, the mixture of water and harmful substances and dust in the box body 1 flow out from the water outlet pipe 9. When there is no need to replace the mixture of water and harmful substances, the operator only needs to loosen the sliding rod 11, the reset spring 12 is reset and drives the sliding rod 11 to reset, and the sliding rod 11 blocks the water inlet pipe 8 and the water outlet pipe 9 again.

[0019] Embodiment 2: Based on embodiment 1, Figure 3 As shown, a cam 14 is also included. The other end of the stirring rod 5 is connected to the cam 14 through a flat key. Two protrusions are provided on the side of the cam 14 away from the box body 1. The two protrusions on the cam 14 will contact the sliding rod 11 in turn.

[0020] Secondly, when the stirring rod 5 rotates, the cam 14 will be driven to rotate, and the two protrusions on the cam 14 will contact the sliding rod 11 in turn. When the protrusion on the cam 14 contacts the sliding rod 11, the sliding rod 11 will move away from the servo motor 7, and the reset spring 12 will be compressed. When the protrusion on the cam 14 is separated from the sliding rod 11, the reset spring 12 will reset and drive the sliding rod 11 to move toward the servo motor 7, and the sliding rod 11 will reciprocate in the direction of approaching or away from the servo motor 7. The water in the box 1 will be continuously replaced, and the dust precipitated in the water will be discharged. The treated exhaust gas will be discharged through the exhaust pipe 13, thereby improving the exhaust gas treatment efficiency. When the exhaust gas treatment is completed, the operator can turn off the servo motor 7.

[0021] Embodiment 3: Based on embodiment 2, Figure 3-Figure 4As shown, it also includes a connecting rod 15, a compression spring 16, a filter screen 17 and an activated carbon filter 18. The connecting rod 15 is slidably connected to the side of the box body 1 close to the servo motor 7. An eccentric wheel is provided at the end of the stirring rod 5 close to the servo motor 7. The connecting rod 15 and the eccentric wheel are located in the same horizontal plane. A compression spring 16 is connected between the connecting rod 15 and the box body 1 through a hook. A filter screen 17 is welded to one end of the connecting rod 15. An activated carbon filter 18 is fixedly connected to the top of the filter screen 17. The filter screen 17 and the activated carbon filter 18 are both located in the exhaust pipe 13. The filter screen 17 and the activated carbon filter 18 are used for secondary treatment of the exhaust gas.

[0022] Finally, when the stirring rod 5 rotates, it will drive the eccentric wheel to rotate, and the rotation of the eccentric wheel will contact the connecting rod 15. When the eccentric wheel contacts the connecting rod 15, the connecting rod 15 will move away from the stirring rod 5, the compression spring 16 will be compressed, and the connecting rod 15 will drive the filter screen 17 and the activated carbon filter 18 to move horizontally. When the eccentric wheel is separated from the connecting rod 15, the compression spring 16 will reset and drive the connecting rod 15 to move toward the stirring rod 5, thereby driving the filter screen 17 and the activated carbon filter 18 to move back and forth in the direction close to or away from the stirring rod 5, and reciprocate in turn. The filter screen 17 and the activated carbon filter 18 move back and forth, and the exhaust gas passing through the outlet pipe 13 will fully contact the filter screen 17 and the activated carbon filter 18, so that the treated exhaust gas in the box 1 will be secondary treated in the process of passing through the outlet pipe 13, which will be more sufficient and filtered more cleanly.
