Description

Technical Field

[0001] This utility model relates to the field of metallurgical engineering and sintering process technology, and in particular to a sintering cooling waste gas filtration and collection box. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted during human production and daily life, especially from chemical plants, steel mills, pharmaceutical factories, coking plants, oil refineries, and domestic waste gas generated by human life. The emitted waste gas has a strong odor, seriously pollutes the environment and affects human health. Waste gas contains many types of pollutants with very complex physical and chemical properties and varying toxicity. Due to the different raw materials and processes used in industrial production, various harmful gases and solid wastes are emitted, containing various components such as heavy metals, salts, and radioactive substances. For example, in the sintering process of the iron and steel metallurgy industry, the sintering process mixes iron ore powder, fuel, and flux at high temperatures and sinters them into blocks to provide raw materials for blast furnace ironmaking. This process generates a large amount of waste gas containing dust and harmful gases.

[0003] If industrial waste gas is discharged into the atmosphere without being treated to meet standards, it will inevitably lead to a decline in air quality, serious harm to human health, and huge losses to the national economy. Therefore, a series of treatments must be carried out on the waste gas. For example, the waste gas generated in the sintering process in the iron and steel metallurgy industry needs to be filtered after cooling before it can be discharged. In the existing treatment process, most of the sintering cooling waste gas filtration and collection boxes use filter bags for filtration. However, the filter bags are all installed on an integral frame, which makes it inconvenient to replace a small number of individual filter bags. Utility Model Content

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.

[0018] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 An embodiment of this utility model provides a sintering cooling exhaust gas filtration and collection box, including a hollow shell 1. A fixing plate 15 is fixedly connected to the inner wall of the hollow shell 1. Multiple slide rails 17 are fixedly connected to the inner wall of the fixing plate 15. A slide rail 18 is slidably connected to the inner wall of the slide rail 17. A fixing plate 23 is slidably connected to the inner wall of the slide rail 18. Multiple filter bags 20 are slidably connected to the middle of the inner wall of the fixing plate 23. A fixing ring 19 is fixedly connected to the top of the filter bags 20. A handle groove 24 is opened on the front side of the fixing plate 23. A rotating shaft 25 is rotatably connected to the inner wall of the handle groove 24. A handle 26 is rotatably connected to the outer wall of the rotating shaft 25. Pins 21 are slidably connected to the left and right sides of the inner wall of the fixing plate 23. Multiple magnets 22 are fixedly connected to the bottom of the inner wall of the fixing plate 23. A platform 6 is fixedly connected to the bottom of the front side of the hollow shell 1. A climbing mechanism 2 is provided on the front side of the platform 6. The climbing mechanism 2 is used to make equipment maintenance more convenient. Specifically, slide rail 2 18 and slide rail 1 17 cooperate to form a double-layer sliding structure. This design not only increases the stability and flexibility of sliding, but also can withstand a large load, ensuring that there will be no jamming or shaking when the internal components are pulled out and pushed in. The filter bag 20 is the core filter element of the entire filter collection box, with high-efficiency filtration performance and a large filtration area. The filter bag 20 can effectively capture particulate matter and impurities in the exhaust gas, so that the exhaust gas meets environmental protection standards. The fixing ring 19 plays the role of fixing the position of the filter bag 20 and preventing the filter bag 20 from shifting during use. The pin 21 is used to fix the entire sliding structure to prevent it from moving during equipment operation. The magnet 22 not only enhances the fixing effect of the pin 21, but also can be used to determine the engagement state of the pin 21 after it is inserted into place.

[0019] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The climbing mechanism 2 includes multiple hooks 201. The rear side of hook 201 is slidably connected to the top of platform 6. The bottom end of hook 201 is fixedly connected to a connecting post 202. Multiple pedals 203 are fixedly connected to the outer wall of connecting post 202. Multiple suspension rods 204 are fixedly connected to the left and right sides of connecting post 202. Hook 3 208 is provided on the rear side of the outer wall of suspension rod 204. A shelf 207 is fixedly connected to the front side of hook 3 208. Hook 2 205 is provided on the front side of the outer wall of suspension rod 204. Connecting post 206 is fixedly connected to the bottom of hook 2 205. Specifically, the suspension rod 204 provides more functional expansion space for the climbing mechanism 2. The shelf 207 and the hook 208 can be engaged with the corresponding suspension rod 204 as needed to facilitate the placement of tools. The design of the hook 201 makes the entire climbing mechanism 2 easy to place and the climbing position can be adjusted as needed. There is no need for complicated disassembly and reinstallation operations during the process, which greatly improves work efficiency.

[0020] Please see the appendix Figure 1 and attached Figure 2 Multiple inspection doors 7 are rotatably connected to the front side of the outer wall of the hollow shell 1. A handle 8 is fixedly connected to the front side of the inspection door 7. A suspension rod 9 is fixedly connected to the top of the hollow shell 1 near the edge. A bracket 5 is fixedly connected to the bottom of the outer wall of the hollow shell 1 near the edge. An air outlet 14 is opened on the right side of the hollow shell 1. An ash hopper 3 is connected to the bottom of the hollow shell 1. A collection cart 4 is installed at the bottom of the ash hopper 3. Specifically, the second suspension rod 9 can be used to connect the climbing mechanism 2, making it convenient for staff to reach the top of the equipment for maintenance. The air outlet 14 is the channel for the filtered clean exhaust gas to be discharged from the equipment. The ash hopper 3 has an inverted cone shape, which is conducive to collecting and discharging the dust and particulate matter filtered from the exhaust gas. The design of the maintenance door 7 provides a convenient passage for the inspection, maintenance and replacement of the internal components of the equipment.

[0021] Please see the appendix Figure 2 and attached Figure 4 A fan 10 is fixedly connected to the top front side of the hollow shell 1. The output end of the fan 10 is connected to a pipe 11. The rear side of the pipe 11 is connected to an air storage box 12. The inner wall of the air storage box 12 is connected to a pipe 2 13. The top of the inner wall of the pipe 2 13 is connected to multiple pulse solenoid valves 16. The bottom of the inner wall of the pipe 2 13 is connected to multiple nozzles 27. Specifically, the pulse solenoid valve 16 is a key control component of the pulse cleaning system. It can quickly open and close according to a preset time interval and pulse width to realize pulse cleaning of the filter bag 20 inside the hollow shell 1. The air storage tank 12 is a container for storing compressed gas, providing a stable air source for pulse cleaning. The fan 10 is the power source for the entire gas delivery and pulse cleaning system.

[0022] Working principle: When a worker needs to replace a single filter bag 20, the operation is simple and efficient. First, open the inspection door 7 corresponding to the filter bag 20 to be replaced. Then, pull out the pins 21 fixed to both sides of the fixing plate 23. Next, the worker grasps the handle 26 and pulls it outwards with slight force. Thanks to the sliding guide action between the slide rail 17, slide rail 18, and fixing plate 23, the fixing plate 23 can be smoothly pulled out of the equipment. In this way, the worker can easily replace a single filter bag 20. This greatly shortens the replacement time and effectively improves work efficiency. After the filter bag 20 is replaced, the fixing plate 23 is reset to its original position. Then, the pin 21 is reinserted into its original position. Due to the presence of multiple magnets 22 on the bottom of the inner wall of the fixing plate 23, when the pin 21 is engaged, it will immediately attract the magnets 22. This design not only makes it easy for staff to quickly determine the engagement status of the pin 21, but also effectively prevents the pin 21 from loosening during use, ensuring the stability and safety of the equipment operation. The climbing mechanism 2 consists of three parts working together. The section below hook 205 is an extension section. In actual use, if the existing length cannot meet the climbing requirements, the staff can easily engage hook 205 with a suitable suspension rod 1 204 to extend the length of the climbing mechanism 2. Hook 1 201 can be placed on platform 6 or on suspension rod 2 9. Furthermore, hook 1 201 has a sliding function, allowing the staff to freely adjust the position of the climbing mechanism 2 according to the actual needs on site. In addition, the part composed of the storage plate 207 and hook 3 208 is a module that can be engaged with the corresponding suspension rod 1 204 according to specific needs. During the climbing process, the staff can place the required tools, parts, and other items on the storage plate 207, eliminating the need to carry a large number of items while climbing. This reduces the burden and improves the safety of climbing, providing strong support for the inspection, maintenance, and repair of the equipment.

[0023] 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.
