[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] The following gives specific embodiments.

[0026] See also Figures 1-5 The utility model provides a sintering furnace gas recovery equipment, including a gas recovery and purification equipment body 1; a tank body 11 is fixedly connected to the side wall of the gas recovery and purification equipment body 1; an air inlet pipe 12 is fixedly connected to the side wall of the tank body 11; a delivery pipe 13 is fixedly connected between the tank body 11 and the gas recovery and purification equipment body 1; a drain pipe 14 is fixedly connected to the side wall of the tank body 11; a servo motor 15 is fixedly connected to the side wall of the tank body 11; an output end of the servo motor 15 passes through the wall of the tank body 11 and is rotatably connected thereto; a spray port 16 is hingedly connected to the output end of the servo motor 15; a push rod 17 is fixedly connected to the side wall of the spray port 16; A connecting pipe 18 is fixedly connected to the side wall of the tank body 11; a guide pipe 19 is fixedly connected between the spray port 16 and the connecting pipe 18; an annular plate 110 is fixedly connected to the inner wall of the tank body 11; a plurality of protrusions 111 are evenly fixedly connected to the bottom of the annular plate 110; when in use, the air inlet pipe 12 is connected to the gas discharge port of the sintering furnace, and then the external water outlet is connected to the connecting pipe 18, so that water flows into the guide pipe 19 to supply water to the spray port 16. When the gas enters the tank body 11, the servo motor 15 is started at the same time, and the spray port 16 is driven to rotate by the servo motor 15. At this time, water mist can be sprayed through the spray port 16. Later, as the spray port 16 rotates, the push rod 17 rotates to correspond to the position of the convex block 111, the push rod 17 can be lifted up by the convex block 111, so that the spray port 16 is tilted. When the two are staggered, they can be automatically reset under the action of the internal torsion spring at the hinge of the spray port 16. At this time, the spray port 16 can be swung by the continuous rotation of the spray port 16, so that the range of water mist spraying is larger. When the spray port 16 rotates to a certain extent, the servo motor 15 is used to reverse to reduce the entanglement of the guide tube 19. The sprayed water mist is contacted and mixed with the large particle residue in the gas, so that it can fall into the tank body. 11, and the gas is transported into the gas recovery and purification equipment body 1 through the delivery pipe 13 for further treatment, and when enough sewage is collected in the tank 11, the sewage is discharged by opening the pipe plug on the side wall of the drain pipe 14. In this process, the contact between the water mist and the gas can remove the larger particle residue contained in the gas, thereby improving the subsequent purification effect of the gas by the gas recovery and purification equipment body 1. At the same time, the swing of the spray port 16 can increase the spray range of the water mist, improve the removal effect of the large particle residue in the gas, and the sprayed water mist can cool the gas.

[0027] Further, such as Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the side wall of the drain pipe 14 is fixedly connected with a plurality of slide rails 2; the slide rails 2 are evenly distributed on the side wall of the drain pipe 14 and have the same structure; the inner wall of the slide rail 2 is slidably connected with a slider 21; the side wall of the slider 21 is fixedly connected with the same filter net bucket 22; when in use, when the pipe plug is opened to discharge the sewage in the tank body 11, the filter net bucket 22 is moved to the bottom of the drain pipe 14 at the same time, and the slider 21 is inserted into the slide rail 2 for fixing. At this time, when the sewage enters the filter net bucket 22, the impurities and dirt in the sewage can be filtered through the filter net bucket 22, and the dirt and impurities are collected by the filter net bucket 22. In this process, the sewage is filtered by the filter net bucket 22, which can play a filtering role when the sewage is discharged, improve the secondary utilization of the filtered sewage, and reduce the need for secondary filtration when the sewage is directly discharged, resulting in a certain increase in workload.

[0028] Further, such as Figure 2 , Figure 4 As shown, the inner side wall of the filter net bucket 22 is fixedly connected to a driving motor 3; the output end of the driving motor 3 is fixedly connected to a plurality of scrapers 31; the scrapers 31 are evenly distributed on the output end of the driving motor 3 and have the same structure; the side wall of the scraper 31 is fixedly connected to a magnetic block 32; the side wall of the filter net bucket 22 is fixedly connected to a plurality of first elastic rods 33; the first elastic rods 33 are evenly distributed on the side wall of the filter net bucket 22 and have the same structure; the end of the first elastic rod 33 is fixedly connected to a magnetic ball 34; when in use, during the process of filtering sewage through the filter net bucket 22, the driving motor 3 is started at the same time, and the driving motor 3 is used to drive the scraper 31 to rotate, so that the scraper 31 scrapes the inner side wall of the filter net bucket 22, and the magnetic block 32 and the magnetic ball 34 are used to filter the sewage. The magnetic attraction effect, when the magnetic block 32 rotates to correspond to the position of the magnetic ball 34, the magnetic ball 34 can be pulled to knock against the side wall of the filter net bucket 22. At this time, the dirt and impurities attached to the inner wall of the filter net bucket 22 can be scraped off by the vibration of the knocking and the scraping of the scraper 31, so that the water can flow out smoothly. When the magnetic ball 34 and the magnetic block 32 are staggered, the elasticity of the first elastic rod 33 can be used to reset the magnetic ball 34. In this process, the scraping of the scraper 31 and the knocking of the magnetic ball 34 can play an anti-clogging role in the filter net bucket 22 during filtration, thereby improving the filtering effect of the filter net bucket 22 and reducing the risk of dirt and impurities accumulating on the inner wall of the filter net bucket 22 and causing blockage when the filter net bucket 22 is used for a long time.

[0029] Further, such as Figure 5As shown, a spring 4 is fixedly connected to the side wall of the slide rail 2; an insert block 41 is fixedly connected to the end of the spring 4; a slot 42 is opened on the side wall of the slider 21; when in use, the insert block 41 is first pulled, and then the slider 21 is inserted into the slide rail 2, so that the slot 42 can correspond to the position of the insert block 41, and at this time, the insert block 41 is released, and the elasticity of the spring 4 can be used to push the insert block 41 into the side wall of the slot 42, so as to fix the slider 21. In this process, by inserting the insert block 41 into the side wall of the slot 42, the fixing effect of the slider 21 in the slide rail 2 can be increased, the firmness of the filter net bucket 22 when in use can be improved, and the poor fixing effect of the slider 21 in the slide rail 2 can be reduced, which leads to the slider 21 easily sliding out of the slide rail 2 when the filter net bucket 22 is accidentally pulled.

[0030] Further, such as Figure 5 As shown, a pair of elastic sheets 5 are fixedly connected to the side walls of the slide rail 2; the elastic sheets 5 are symmetrically arranged on both sides of the slide rail 2 and have the same structure; a second elastic rod 51 is fixedly connected between the elastic sheet 5 and the slide rail 2; when in use, during the process of inserting the slider 21 into the slide rail 2, the slider 21 will squeeze the elastic sheet 5. At this time, the elasticity of the elastic sheet 5 can be used to apply a certain thrust to the slider 21 to push it toward the middle of the slide rail 2. At the same time, the slider 21 will also slide toward the middle of the elastic sheets 5 on both sides. When the two are staggered, the elasticity of the second elastic rod 51 can be used to quickly reset the elastic sheet 5. In this process, the elastic sheet 5 provided can play a limiting role when the slider 21 is inserted into the slide rail 2, thereby improving the convenience of insertion. At the same time, the second elastic rod 51 can play a role in preventing the elastic sheet 5 from being deformed when it is squeezed, thereby improving the service life of the elastic sheet 5.

[0031] Further, such as Figure 5 As shown, the side wall of the plug block 41 is fixedly connected with a pull ring 6; the side wall of the pull ring 6 is symmetrically fixedly connected with a pair of elastic plates 61; when in use, the pull ring 6 is hooked with fingers, and the pull rings 6 on both sides can be pushed open with fingers. When squeezed to a certain extent, the elastic plates 61 can bounce off the fingers and press the fingers against the side walls of the pull ring 6. At this time, the plug block 41 can be moved by pulling the pull ring 6. In this process, the pull ring 6 is set to facilitate the holding and pulling of the plug block 41. At the same time, the elastic plates 61 can prevent the pull ring 6 from falling off when the fingers are hooked and pulled, thereby reducing the inconvenience of holding the plug block 41, which makes it easy to slip off from its side walls when pulled.

[0032] Further, such as Figure 4As shown, a rubber sleeve 7 is fixedly connected to the side wall of the magnetic ball 34; during use, when the magnetic ball 34 strikes the side wall of the filter mesh hopper 22, the rubber sleeve 7 can be used to block between the two to protect the filter mesh hopper 22. During this process, through the rubber sleeve 7 provided, it can play a protective role when the magnetic ball 34 strikes the side wall of the filter mesh hopper 22, improve the service life of the filter mesh hopper 22, and reduce the damage of the filter mesh hopper 22 that is likely to occur when the magnetic ball 34 strikes the filter mesh hopper 22 for a long time, thereby affecting the service life.

[0033] Working principle: When in use, the air inlet pipe 12 is connected to the gas discharge port of the sintering furnace, and then the external water outlet is connected to the connecting pipe 18, so that the water flows into the guide pipe 19 to supply water to the spray port 16. When the gas enters the tank body 11, the servo motor 15 is started at the same time, and the spray port 16 is driven to rotate by the servo motor 15. At this time, water mist can be sprayed through the spray port 16. After that, as the spray port 16 rotates, the push rod 17 rotates to correspond to the position of the protrusion 111. The push rod 17 can be lifted up by the protrusion 111, so that the spray port 16 is tilted. When the two are staggered, the internal torsion spring at the hinge of the spray port 16 can automatically reset. At this time, the continuous rotation of the spray port 16 can make the spray port 16 swing. The range of water mist spraying is made larger. When the spray port 16 rotates to a certain extent, the servo motor 15 is used to reverse to reduce the entanglement of the guide tube 19. The sprayed water mist is contacted and mixed with the large particle residue in the gas, so that it can fall into the tank body 11, and the gas is transported into the gas recovery and purification equipment body 1 through the delivery pipe 13 for further treatment. When enough sewage is collected in the tank body 11, the sewage is discharged by opening the pipe plug on the side wall of the drain pipe 14. When in use, when the pipe plug is opened to discharge the sewage in the tank body 11, the filter net bucket 22 is moved to the bottom of the drain pipe 14 at the same time, and the slider 21 is inserted into the slide rail 2 for fixing. At this time, when the sewage enters the filter net bucket 22, it passes through the filter net The bucket 22 can filter impurities and dirt in the sewage, and collect the dirt and impurities through the filter net bucket 22. When in use, during the process of filtering the sewage through the filter net bucket 22, the drive motor 3 is started at the same time, and the drive motor 3 is used to drive the scraper 31 to rotate, so that the scraper 31 scrapes the inner wall of the filter net bucket 22, and the magnetic attraction between the magnetic block 32 and the magnetic ball 34 is used. When the magnetic block 32 rotates to correspond to the position of the magnetic ball 34, the magnetic ball 34 can be pulled to knock against the side wall of the filter net bucket 22. At this time, the dirt and impurities attached to the inner wall of the filter net bucket 22 can be scraped off by the vibration of the knocking and the scraping of the scraper 31, so that the water can flow out smoothly. When the magnetic ball 34 is staggered with the magnetic block 32, the first elastic rod 33 is used to pull the magnetic ball 34 to the inner wall of the filter net bucket 22. The elasticity of the spring 4 can reset the magnetic ball 34. When in use, first pull the plug block 41, and then insert the slider 21 into the slide rail 2, so that the slot 42 corresponds to the position of the plug block 41. At this time, release the plug block 41, and use the elasticity of the spring 4 to push the plug block 41 onto the side wall of the slot 42, so as to fix the slider 21. When in use, during the process of inserting the slider 21 into the slide rail 2, the slider 21 will squeeze the elastic sheet 5. At this time, the elasticity of the elastic sheet 5 can be used to apply a certain thrust to the slider 21 to push it toward the middle of the slide rail 2. At the same time, the slider 21 will also slide toward the middle of the elastic sheets 5 on both sides. When the two are staggered, the elasticity of the second elastic rod 51 can be used to quickly reset the elastic sheet 5. When in use, by hooking the pull ring 6 with your fingers,The fingers can push open the pull rings 6 on both sides. When squeezed to a certain extent, the elastic plate 61 can bounce off the fingers and press the fingers against the side walls of the pull rings 6. At this time, by pulling the pull rings 6, the insertion blocks 41 can be moved. When in use, when the magnetic balls 34 knock on the side walls of the filter net hopper 22, the rubber sleeve 7 can be blocked between the two to protect the filter net hopper 22.,
