Description

Technical Field

[0001] The utility model relates to the technical field of industrial furnaces, in particular to a smoke exhaust device for an industrial electric furnace. Background Art

[0002] Industrial electric furnaces are heating devices widely used in industries such as metal processing, chemical industry, electronics, and ceramics. They convert electrical energy into heat energy to quickly and efficiently heat materials. There are various types of such electric furnaces, such as resistance furnaces, induction furnaces, arc furnaces, etc., to meet different heating requirements. Their characteristics include precise control of heating temperature and time, the ability to provide a stable heating environment, and ensure product quality. The flue gas of industrial electric furnaces is the waste gas generated during the heating process, which contains various components, such as particulate matter, harmful gases, etc. These flue gases need to be properly treated to reduce environmental pollution and the impact on human health.

[0003] The treatment of flue gas from industrial electric furnaces is an important environmental protection measure. It uses methods such as filtration, adsorption, and combustion to effectively remove harmful substances in the flue gas, reduce pollution to the atmospheric environment, and reduce the harm of harmful gases to human health. At the same time, it meets the requirements of environmental protection regulations and avoids being punished for exceeding emissions. In addition, some treatment methods can also recover useful substances, improve equipment performance, extend service life, optimize production efficiency and product quality.

[0004] One of the most common treatment methods for the flue gas generated by industrial electric furnaces is mechanical dust collectors, such as cyclone dust collectors.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figure 2 - Figure 4 As shown in [the relevant figure], an embodiment provided by the present invention is: A smoke exhaust device for an industrial electric furnace, including a support 1. One side of the support 1 is fixedly connected with a first filter pipe 2. The other side inside the support 1 is fixedly connected with a second filter pipe 3. One side of the outer wall of the first filter pipe 2 is fixedly connected with a smoke inlet pipe 12. One end of the smoke inlet pipe 12 is fixedly connected inside the first filter pipe 2. A double-layer filter pipe 13 is fixedly connected inside the first filter pipe 2. The top of the outer wall of the double-layer filter pipe 13 is threadedly connected with a top cover 9. The top of the double-layer filter pipe 13 is fixedly connected with a connecting pipe 8. One end of the connecting pipe 8 is fixedly connected with a check valve 11. The output end of the check valve 11 is fixedly connected with a smoke outlet pipe 14. The outer wall of the smoke outlet pipe 14 is fixedly connected inside the second filter pipe 3. The outer wall of the smoke outlet pipe 14 is rotatably connected with a sleeve 15. A plurality of stirring blades 16 are fixedly connected to the outer wall of the sleeve 15. A plurality of smoke outlets 17 are provided on the outer wall of the smoke outlet pipe 14. The outer wall of the sleeve 15 is rotatably connected inside the second filter pipe 3. A motor 7 is fixedly connected inside the support 1. The output end of the motor 7 is fixedly connected with a first driving wheel 19. The bottom of the sleeve 15 is fixedly connected with a second driven wheel 20. A belt 21 is arranged between the second driven wheel 20 and the first driving wheel 19. One side of the top of the second filter pipe 3 is fixedly connected with an air outlet pipe 10;

[0035] Specifically, the flue gas is introduced into the interior of the first filter tube 2 through the smoke inlet pipe 12. A double-layer filter tube 13 is arranged inside the first filter tube 2, and an adsorbent is filled inside the double-layer filter tube 13. A negative pressure is generated by the fan 18 at the outlet of the double-layer filter tube 13, which promotes the rapid passage of the flue gas through the double-layer filter tube 13 and into the interior of the double-layer filter tube 13. The larger impurities in the flue gas are adsorbed and removed by the adsorbent inside the double-layer filter tube 13. At the same time, a top cover 9 is arranged at the top of the double-layer filter tube 13, which facilitates the replacement of the internal adsorbent and ensures the continuous and stable adsorption effect. The treated flue gas enters the smoke outlet pipe 14 inside the second filter tube 3 through the connecting pipe 8. The one-way valve 11 prevents backflow, ensuring the stable flow direction of the flue gas and avoiding the backflow phenomenon. A gas permeable membrane is arranged at the smoke outlet 17 inside the smoke outlet pipe 14, which can not only let the flue gas discharge from the second filter tube 3 but also play a certain filtering role, further improving the filtering effect. The driving wheel one 19 is driven by the motor 7, and the driven wheel two 20 is driven to rotate through the belt 21, realizing the stable rotation of the sleeve 15. The stirring blades 16 on the sleeve 15 stir, enabling the flue gas to be fully mixed with the internal chemical reaction liquid, improving the efficiency of the chemical reaction, and better removing the chemical impurities in the flue gas. Finally, the treated flue gas is led out through the air outlet pipe 10, achieving the purpose of purifying the flue gas and reducing environmental pollution.

[0036] Refer to Figure 1 、 Figure 5 And Figure 6 , the outer wall of the smoke inlet pipe 12 is threadedly connected with a driving ring 22. A limiting block 23 is slidably connected inside the driving ring 22. One end of the limiting block 23 is fixedly connected with a slider 24. One side of the slider 24 is rotatably connected with a transmission plate 25. An annular array of limiting rods 27 is fixedly connected to one side of the outer wall of the smoke inlet pipe 12. One side of the transmission plate 25 is rotatably connected with a clamping jaw 26. A limiting groove 28 is formed inside the clamping jaw 26. The outer wall of the limiting rod 27 is slidably connected inside the limiting groove 28. A sealing assembly is arranged inside the smoke inlet pipe 12, and the sealing assembly is used for sealing when the smoke inlet pipe 12 is connected to the smoke outlet. The sealing assembly includes a sealing gasket 29, and the outer wall of the sealing gasket 29 is fixedly connected to one side of the inner wall of the smoke inlet pipe 12;

[0037] Specifically, when the device processes the flue gas generated by the industrial electric furnace, the driving ring 22 can be driven, so that the driving ring 22 pulls the slider 24 through the limiting block 23, and then the slider 24 pulls the transmission plate 25. Then, the transmission plate 25 can pull the clamping jaw 26 to retract. Since the limiting rod 27 slides in the limiting groove 28 inside the clamping jaw 26, the clamping jaw 26 can be clamped towards the middle, so that the clamping jaw 26 clamps the smoke exhaust port of the industrial electric furnace. By driving the driving ring 22, the movement of the clamping jaw 26 can be controlled. By pulling the slider 24 through the limiting block 23, the slider 24 can move in a straight line direction, thus ensuring that the movement track of the clamping jaw 26 is a straight line. By pulling the transmission plate 25 by the slider 24, since the limiting rod 27 slides in the limiting groove 28 inside the clamping jaw 26, the movement range of the clamping jaw 26 can be restricted, so that the clamping jaw 26 can be clamped towards the middle, and the clamping jaw 26 can clamp the smoke exhaust port, thereby improving the stability and reliability of the clamping jaw 26 clamping the smoke exhaust port.

[0038] Refer to Figure 1 And Figure 2 , a two-way pump 4 is fixedly connected to the top of the bracket 1. The output end of the two-way pump 4 is fixedly connected to a first water suction pipe 5, and the output end of the two-way pump 4 is fixedly connected to a second water suction pipe 6. One end of the second water suction pipe 6 is fixedly connected to one side inside the second filter pipe 3;

[0039] Specifically, a two-way pump 4 is arranged on one side of the second filter pipe 3. The two-way pump 4 can discharge or introduce the chemical reaction liquid through the second water suction pipe 6, so as to facilitate the replacement of the internal chemical reaction liquid. The setting of the two-way pump 4 makes the discharge and introduction of the chemical reaction liquid more convenient, and the replacement operation can be quickly completed, improving the work efficiency.

[0040] Working principle: When the device processes the flue gas generated by the industrial electric furnace, the driving ring 22 can be driven to pull the slider 24 through the limiting block 23, so that the slider 24 pulls the transmission plate 25, and then the transmission plate 25 can pull the clamping jaw 26 to retract. Since the limiting rod 27 slides in the limiting groove 28 inside the clamping jaw 26, the clamping jaw 26 can be clamped towards the middle, so that the clamping jaw 26 clamps the smoke outlet of the industrial electric furnace, and the flue gas is introduced into the first filter pipe 2 through the smoke inlet pipe 12. A double-layer filter pipe 13 is arranged inside the first filter pipe 2, and an adsorption substance can be filled inside the double-layer filter pipe 13. Then, a negative pressure is generated by the fan 18 at the outlet of the double-layer filter pipe 13, so that the flue gas inside the first filter pipe 2 passes through the double-layer filter pipe 13 and enters the inside of the double-layer filter pipe 13. Thus, the larger impurities in the flue gas are adsorbed and removed by the adsorption substance inside the double-layer filter pipe 13. At the same time, a top cover 9 is arranged at the top of the double-layer filter pipe 13 to replace the adsorption substance inside the double-layer filter pipe 13. The treated flue gas will pass through the connecting pipe 8 into the smoke outlet pipe 14 inside the second filter pipe 3, and the one-way valve 11 is used to prevent its backflow. The flue gas will be discharged through the smoke outlet 17 inside the smoke outlet pipe 14. A gas permeable membrane is arranged on the smoke outlet 17, which can allow the flue gas to discharge from the second filter pipe 3. At the same time, the motor 7 drives the first driving wheel 19, and then drives the second driven wheel 20 to rotate through the belt 21. Then, the second driven wheel 20 can drive the sleeve 15 to rotate, so that the stirring blades 16 on the sleeve 15 stir, so that the flue gas is fully mixed with the internal chemical reaction liquid, so as to react and remove the chemical impurities in the flue gas, and is led out by the air outlet pipe 10. A two-way pump 4 is arranged on one side of the second filter pipe 3, and the two-way pump 4 can discharge or introduce the chemical reaction liquid through the second water suction pipe 6, so as to facilitate the replacement of the internal chemical reaction liquid.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
