Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation in arc welding rooms, and in particular to a ventilation component for arc welding rooms. Background Technology
[0002] The ventilation of an arc welding room is achieved by using a forced ventilation system to quickly expel high concentrations of fumes, harmful gases (such as ozone and nitrogen oxides), and high-temperature air generated during the welding process, while introducing fresh air to maintain indoor air quality and a safe working environment. Typically, a top exhaust hood and a side suction device are used to capture rising fumes, which, together with bottom or side wall air inlets, form a directional airflow.
[0003] In existing arc welding rooms, exhaust gas is discharged directly during ventilation. The high temperature carried in the exhaust gas can cause the temperature of the transmission pipes to rise directly, which can lead to pipe rupture over time and affect the service life. At the same time, particulate matter in the exhaust gas can be blocked by the filter screen during the discharge process. Excessive accumulation can cause exhaust blockage and affect the normal operation of the equipment. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figures 1-3This utility model provides an embodiment of an arc welding chamber ventilation assembly, comprising: a welding chamber 1 for support; a ventilation pump 3 fixedly connected to a protruding plate of the welding chamber 1; an air inlet pipe 2 fixedly connected to the output end of the ventilation pump 3; the inner side of the air inlet pipe 2 fixedly connected to the left side of the welding chamber 1; an extraction pipe 5 fixedly connected to the left side of the top of the welding chamber 1; an extraction pump 4 fixedly connected to the outside of the extraction pipe 5; a cooling box 6 fixedly connected to the top of the welding chamber 1 to the right side of the extraction pipe 5; and a cooling spiral pipe 15 fixedly connected to the right side of the extraction pipe 5. The bottom end of the cooling spiral tube 15 is fixedly connected to the external discharge pipe 17. The cooling box 6 is equipped with a water flow cooling component to cool the high temperature gas. The water flow cooling component includes a cooling air plate 14 fixed inside the cooling box 6. The top end of the cooling air plate 14 is fixedly connected to the lower air supply pipe 9. The outer top end of the lower air supply pipe 9 passes through the top end of the cooling box 6 and is fixedly connected to the cooling air pump 8. The bottom end of the cooling air pump 8 is fixed to the top end of the cooling box 6 by a mounting bracket. A one-way valve 10 is fixedly connected to the upper outer side of the lower air supply pipe 9.
[0028] The air exchange pump 3 delivers fresh air from outside to the welding chamber 1 through the air inlet pipe 2. At the same time, the exhaust pump 4 draws the exhaust gas from the welding chamber 1 upwards to the cooling spiral tube 15 through the exhaust pipe 5. During the cooling process, the cooling pump 8 starts and delivers outside air to the cooling air plate 14 through the lower air delivery pipe 9. The air is then evenly discharged through its slot. The cooling box 6 is filled with coolant. The large-area cooling spiral tube 15 significantly increases the heat exchange area. The coolant continuously reduces the temperature of the outer wall of the spiral tube. Meanwhile, the cooling air plate 14 provides auxiliary cooling for the coolant, forming a dual cooling mechanism. This design not only greatly improves the treatment efficiency of high-temperature exhaust gas, but also effectively prevents the pipe from cracking due to high temperature, ensuring the long-term stable operation of the system.
[0029] Refer to entry 4. Figure 5 and Figure 6A filter sleeve 12 is installed on the right side of the top of the welding chamber 1. Multiple activated carbon filter plates 16 are fixedly connected inside the filter sleeve 12. A rotating rod 26 is rotatably connected inside the filter sleeve 12. A second bevel gear 25 is fixedly connected to the left side of the rotating rod 26. A drive motor 13 is fixedly connected to the right side of the filter sleeve 12, and the drive end of the drive motor 13 is fixedly connected to the right side of the rotating rod 26. A particle blocking assembly is installed inside the filter sleeve 12 to achieve stable exhaust operation. The particle blocking assembly includes a support frame 21 located inside the filter sleeve 12. A particle blocking mesh plate 22 is fixedly connected inside the support frame 21. A rotating column 23 is rotatably connected inside the particle blocking mesh plate 22. The left side of the rotating column 23 is fixedly connected to the left side. A rotating sleeve 19 is connected, and multiple scrapers 20 are fixedly connected to the outer circumference of the rotating sleeve 19. A first bevel gear 24 is fixedly connected to the bottom end of the rotating column 23. A second bevel gear 25 is meshed with the first bevel gear 24. The outer end of the external discharge pipe 17 is fixedly connected to the left side of the filter sleeve 12. The outer end of the rotating rod 26 is rotatably connected to the inside of the activated carbon filter plate 16. A collection round frame 18 is nested on the left side of the filter sleeve 12. An installation sleeve 11 is fixedly connected to the top of the collection round frame 18. Magnetic blocks 7 are fixedly connected to both sides of the bottom end of the installation sleeve 11. The magnetic blocks 7 are distributed on the outside and magnetically attracted to the inside of both sides of the filter sleeve 12. Multiple drive motors 13 are fixedly connected to the inner side of the scraper 20 to achieve the cleaning of surface particles.
[0030] The exhaust gas first enters the filter sleeve 12 through the exhaust pipe 17. When the exhaust gas comes into contact with the particulate blocking mesh 22, the particulate matter is effectively intercepted. Then, the drive motor 13 starts, driving the rotating rod 26 to rotate. Through the meshing transmission of the first bevel gear 24 and the second bevel gear 25, the rotating column 23 is driven to rotate synchronously. At this time, the edge of the scraper 20 contacts the left side of the support frame 21, scraping off the particulate matter attached to the left side of the particulate blocking mesh 22. The scraped particulate matter slides down the inclined angle into the collection round frame 18 for centralized collection. When cleaning is required, the accumulated particulate matter can be removed by simply pushing the mounting sleeve 11 outward. This design not only significantly improves the operational stability of the exhaust system, but also greatly simplifies the waste particulate matter treatment process, and has the advantages of simple operation and convenient maintenance.
[0031] Working principle: External air is introduced into the welding chamber 1 through the air inlet pipe 2 by the air exchange pump 3. The exhaust pump 4 is activated to discharge the gas inside the welding chamber 1 upwards through the exhaust pipe 5, thereby discharging the exhaust gas into the cooling spiral tube 15. At this time, the cooling air pump 8 is activated to introduce external air into the lower air outlet pipe 9, thereby discharging the air into the cooling air plate 14. The air is discharged outwards through the slot of the cooling air plate 14. Cooling fluid is added to the cooling box 6. The cooling spiral tube 15 has a large surface area, increasing the area for air cooling. The water flow lowers the external temperature of the cooling spiral tube 15, while the cooling air plate 14 cools the coolant. To improve the cooling effect of the device, the exhaust gas is discharged into the interior of the filter sleeve 12 through the exhaust pipe 17. The airflow contacts the particle blocking mesh plate 22, blocking the particulate matter in the exhaust gas. At this time, the drive motor 13 is started to rotate the rotating rod 26, thereby rotating the rotating column 23 through the meshing between the second bevel gear 25 and the first bevel gear 24. The edge of the scraper 20 contacts the left side of the support frame 21, thereby scraping off the particles on the left side of the particle blocking mesh plate 22. As the angle of inclination increases, the particles fall into the interior of the collection circle frame 18, and are collected by the frame inside the collection circle frame 18. The mounting sleeve 11 is then pulled outward to clean up the accumulated particles.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
