DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0025] Reference Figures 1 to 4 As shown, a waste gas treatment device for the production of positive electrode materials for sodium ion batteries described in an embodiment of the utility model comprises a treatment device housing 1; an air inlet 12 is provided in the middle of the side wall of the treatment device housing 1; an exhaust port 13 is provided at the top of the treatment device housing 1; a filter plate 14 is fixedly connected to the inside of the treatment device housing 1; the filter plate 14 is located between the air inlet 12 and the exhaust port 13; a motor 15 is fixedly connected to the bottom of the inside of the treatment device housing 1; a connecting rod 16 is fixedly connected to the output end of the motor 15; a sliding column 17 is slidably connected to the top of the connecting rod 16; a spring 18 is installed inside the sliding column 17; the other end of the spring 18 is fixedly connected to the top of the connecting rod 16; a scraper 19 is fixedly connected to the top of the sliding column 17 During operation, the production waste gas is injected into the interior of the treatment device housing 1 from the air inlet 12. As the waste gas content inside the treatment device housing 1 increases, the waste gas will rise and be discharged from the interior of the treatment device housing 1 through the exhaust port 13. In this process, some particulate matter in the waste gas will be filtered by the filter plate 14. As time goes by, a large amount of particulate matter will accumulate at the bottom of the filter plate 14. At this time, the starting motor 15 drives the connecting rod 16 and the sliding column 17 to rotate, and then the scraper 19 located on the top of the sliding column 17 will scrape the bottom of the filter plate 14 to brush off the impurities attached to the bottom of the filter plate 14. Through the above structure, the particulate matter in the waste gas can be reduced from blocking the surface of the filter plate 14 when being filtered, thereby reducing the filtering effect of the filter plate 14.

[0026] Reference Figures 1 to 5As shown, a liquid storage box 2 is fixedly connected to the side wall of the treatment device shell 1; a liquid guide tube 21 is fixedly connected to the bottom end of the liquid storage box 2; the liquid guide tube 21 penetrates the side wall of the treatment device shell 1 and enters the interior of the treatment device shell 1, and the end of the liquid guide tube 21 is located between the exhaust port 13 and the filter plate 14; a hollow bolt 22 is threadedly connected to the top of the liquid storage box 2; a first elastic membrane 23 is fixedly connected to the top of the interior of the liquid storage box 2; a small hole is opened in the middle of the first elastic membrane 23, and the small hole is located below the central hollow of the hollow bolt 22; when working, clean water is added to the interior of the liquid storage box 2. Under normal circumstances, the small hole in the middle of the first elastic membrane 23 is in a closed state. At this time, the existence of air pressure above the interior of the liquid storage box 2 prevents the clean water in the hollow bolt 22 from flowing out through the liquid guide tube 21. The hollow bolt 22 is rotated to move the hollow bolt 22 toward the direction of the first elastic membrane 23, thereby The first elastic membrane 23 is squeezed to open the first elastic membrane 23, and then the small hole in the middle of the first elastic membrane 23 is opened, so that external air can enter the interior of the liquid storage box 2 through the hollow hole and the small hole in the middle of the hollow bolt 22. At this time, the liquid in the liquid storage box 2 will flow out along the liquid guide tube 21. By adjusting the opening size of the small hole in the middle of the first elastic membrane 23, water is dripped from the end of the liquid guide tube 21 onto the filter plate 14 at a suitable speed, thereby soaking the filter plate 14 and improving the filtering capacity of the filter plate 14. At the same time, the particles filtered by the filter plate 14 are adsorbed to each other due to water, so that they can fall in a cluster after being scraped by the scraper 19, and it is difficult for them to rise with the exhaust gas. Through the above structure, the filtering effect of the filter plate 14 can be improved, and the impurities cleaned and dropped by the scraper 19 are difficult to flow with the exhaust gas again and block the filter plate 14, thereby improving the filtering effect.

[0027] Reference Figures 1 to 6 As shown, a fixing sleeve 3 is fixedly connected to the middle part of the filter plate 14; a slider 31 is slidably connected to the middle part of the fixing sleeve 3; an inclined surface is provided at the bottom of the slider 31; during operation, as the scraper 19 rotates, the middle part of the scraper 19 will push the slider 31 upward when passing through the slider 31, and after the scraper 19 leaves the bottom of the fixing sleeve 3, the slider 31 will fall back to its original position along the slider 31, thereby driving the filter plate 14 to vibrate due to impact and collision, and shaking off some impurities attached to the bottom of the filter plate 14. Through the above structure, the cleaning effect of the impurities attached to the bottom of the filter plate 14 can be further improved, thereby reducing the influence of the accumulation of impurities on the filtering ability of the filter plate 14.

[0028] Reference Figures 1 to 3As shown, two groups of track plates 4 are fixedly connected to the inner side of the processing device housing 1; a pair of slag collecting boxes 41 are slidably installed on the top of the two groups of track plates 4; adjacent surfaces of the pair of slag collecting boxes 41 are provided with grooves 42; the connecting rod 16 is located between the pair of grooves 42; during operation, after impurities fall, they will fall into the inside of the pair of slag collecting boxes 41, and will not fall on the surface of the motor 15 to affect the operation of the motor 15. When there are a lot of impurities accumulated inside the slag collecting box 41, the slag collecting box 41 can be taken out to clean the impurities. Through the above structure, the situation where impurities fall on the surface of the motor 15 and affect the operation of the motor 15 can be reduced.

[0029] Reference Figures 1 to 3 As shown, a plurality of elastic bands 5 are fixedly connected to the middle part of the inner part of the treatment device housing 1; a second elastic membrane 51 is fixedly connected to the ends of the plurality of elastic bands 5; the second elastic membrane 51 is located directly below the end of the liquid guiding tube 21; during operation, after water drops from the end of the liquid guiding tube 21, the water drops will fall on the second elastic membrane 51. Since the second elastic membrane 51 is a taut elastic membrane, the water drops falling on the second elastic membrane 51 will splash around, so that they can fall on the top of the filter plate 14 more evenly, making the filter plate 14 more evenly soaked, thereby further improving the filtering effect of the filter plate 14.

[0030] Reference Figures 1 to 3 As shown, a fixed shaft 6 is fixedly connected to the side wall of the processing device housing 1; the fixed shaft 6 is located above the slag collecting box 41; the middle part of the fixed shaft 6 is rotatably connected to a clamping plate 61; during operation, after a pair of slag collecting boxes 41 are installed into the interior of the processing device housing 1, the end of the clamping plate 61 will be located below the fixed shaft 6 due to its own gravity, and the side wall of the slag collecting box 41 will be blocked, so that the slag collecting box 41 is difficult to be separated from the interior of the processing device housing 1 due to the vibration of the equipment when the equipment is running, thereby reducing the occurrence of impurities falling on the surface of the motor 15.

[0031] Reference Figure 4 As shown, a plurality of bristles 7 are fixedly connected to the top of the scraper 19; the plurality of bristles 7 are densely arranged on the top of the scraper 19; during operation, as the scraper 19 rotates, the plurality of bristles 7 will extend into some filter pores at the bottom of the filter plate 14 to clean some of the accumulated impurities inside the filter plate 14. Through the above structure, the decrease in the filtering capacity of the filter plate 14 caused by the clogging of impurities can be further reduced.

[0032] Reference Figure 6As shown, the fixing sleeve 3 and the slider 31 are both plastic products; a counterweight block 8 is fixedly connected to the interior of the slider 31; during operation, since the fixing sleeve 3 and the slider 31 are both plastic products, they will not rust and get stuck due to water vapor corrosion like metal products. At the same time, the setting of the counterweight block 8 can increase the impact force of the slider 31 when it moves down, thereby increasing the vibration strength of the filter plate 14, so that more impurities can be shaken off.

[0033] During operation, the production waste gas is injected into the interior of the treatment device housing 1 from the air inlet 12. As the waste gas content inside the treatment device housing 1 increases, the waste gas rises and is discharged from the interior of the treatment device housing 1 through the exhaust port 13. In this process, some particulate matter in the waste gas will be filtered by the filter plate 14. As time goes by, a large amount of particulate matter will accumulate at the bottom of the filter plate 14. At this time, the start motor 15 drives the connecting rod 16 and the sliding column 17 to rotate, and then the scraper 19 located at the top of the sliding column 17 will scrape the bottom of the filter plate 14 to brush off the impurities attached to the bottom of the filter plate 14. Clean water is added to the inside of the liquid storage box 2. Under normal circumstances, the small hole in the middle of the first elastic membrane 23 is in a closed state. At this time, the existence of the air pressure above the inside of the liquid storage box 2 makes the hollow bolt 22 The clean water will not flow out through the liquid guide tube 21, and the hollow bolt 22 is rotated to move the hollow bolt 22 toward the direction of the first elastic membrane 23, thereby squeezing the first elastic membrane 23 to open the first elastic membrane 23, and then the small hole in the middle of the first elastic membrane 23 is opened, so that the external air can enter the interior of the liquid storage box 2 through the hollow hole and the small hole in the middle of the hollow bolt 22. At this time, the liquid in the liquid storage box 2 will flow out along the liquid guide tube 21, and by adjusting the opening size of the small hole in the middle of the first elastic membrane 23, water is dripped from the end of the liquid guide tube 21 onto the top of the filter plate 14 at a suitable speed, thereby soaking the filter plate 14, improving the filtering capacity of the filter plate 14, and at the same time making the particles filtered by the filter plate 14 adsorbed to each other due to the water, so that the particles filtered by the filter plate 14 are After being scraped, the impurities 9 can fall in a mass and are difficult to rise with the exhaust gas. As the scraper 19 rotates, the middle part of the scraper 19 will push the slider 31 upward when passing through the slider 31. After the scraper 19 leaves the bottom of the fixed sleeve 3, the slider 31 will fall back to its original position along the slider 31, thereby driving the filter plate 14 to vibrate due to the impact and collision, and vibrating some impurities attached to the bottom of the filter plate 14. After the impurities fall, they will fall into the inside of a pair of slag collection boxes 41, and will not fall on the surface of the motor 15 to affect the operation of the motor 15. When there are many impurities accumulated inside the slag collection box 41, the slag collection box 41 can be taken out to clean the impurities. After the water droplets drip from the end of the liquid guide tube 21, the water droplets will fall on the top of the second elastic membrane 51. Since the second elastic membrane 51 is a stretched The water droplets falling on the second elastic membrane 51 will splash around, so that they can fall on the top of the filter plate 14 more evenly, making the filter plate 14 more evenly soaked. After the pair of slag boxes 41 are installed into the interior of the processing device housing 1, the end of the clamping plate 61 will be under the fixed shaft 6 due to its own gravity, and block the side wall of the slag box 41, so that the slag box 41 is difficult to be separated from the interior of the processing device housing 1 due to the vibration of the equipment when the equipment is running. With the rotation of the scraper 19, a plurality of bristles 7 will extend into some filtering pores at the bottom of the filter plate 14 to clean up some accumulated impurities inside the filter plate 14. Since the fixed sleeve 3 and the slider 31 are both plastic products, they will not rust and get stuck due to water vapor corrosion like metal products.At the same time, the setting of the counterweight block 8 can increase the impact force of the slider 31 when it moves down, thereby increasing the vibration strength of the filter plate 14.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
