[0002] In the mold manufacturing and metal heat treatment industries, tempering furnaces are key equipment used to eliminate quenching stress in workpieces, stabilize their microstructure and dimensions, and improve their mechanical properties.

[0003] During the tempering process, the mold material itself may contain oil, coatings or additives. These substances will decompose, volatilize and oxidize at high temperatures, resulting in a large amount of flue gas containing complex components. Therefore, a flue gas treatment device is needed to purify the flue gas emitted from the tempering furnace so that it can meet the emission standards.

[0004] However, in the existing technology, the flue gas from the tempering furnace contains a large number of particulate impurities. If these impurities are directly discharged into the flue gas treatment device, they are prone to adhesion and accumulation over a long period of time, which affects the smoothness of the flue gas flow and the flue gas filtration effect, thus having a certain impact on the flue gas treatment. Therefore, in order to address the above problems, a flue gas treatment device for tempering furnaces used in mold processing is proposed. Utility Model Content

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-6This utility model provides a flue gas treatment device for a tempering furnace used in mold processing, including a flue gas treatment device body 1; a receiving pipe 11 is fixedly connected to the side wall of the flue gas treatment device body 1; a pair of slide rails 12 are fixedly connected to the inner side wall of the receiving pipe 11; the slide rails 12 are symmetrically arranged on both sides of the receiving pipe 11 and have the same structure; a fixing block 13 is slidably connected to the inner side wall of the slide rail 12; a rubber pad 14 is fixedly connected to the side wall of the fixing block 13; a filter screen plate 15 is fixedly connected to the side wall of the fixing block 13; the side wall of the filter screen plate 15 can rotate. A spiral impeller 16 is connected and penetrates its wall; a pair of fixing plates 17 are fixedly connected to the side wall of the spiral impeller 16; the fixing plates 17 are symmetrically arranged on both sides of the spiral impeller 16 and have the same structure; multiple cleaning brushes 18 are evenly fixed to the side wall of the fixing plates 17; in use, first, the filter screen 15 and the spiral impeller 16 are placed into the receiving pipe 11, the fixing block 13 is inserted into the slide rail 12, and the fixing block 13 is fixed by the friction between the rubber pad 14 and the slide rail 12, thereby realizing the cleaning of the filter screen 15 and the spiral impeller 16. After installation and fixing, the external pipe is connected and fixed to the receiving pipe 11. The flue gas generated by the tempering furnace first enters the receiving pipe 11. The filter screen 15 forms a flue gas filtration channel, and large particulate impurities in the flue gas are intercepted and filtered by the filter screen 15. At the same time, the flue gas flow will drive the spiral impeller 16 connected to the side wall of the filter screen 15 to rotate. The symmetrical fixed plate 17 fixed to the side wall of the spiral impeller 16 rotates synchronously with the impeller. The multiple cleaning brushes 18 evenly distributed on the side wall of the fixed plate 17 will then move relative to the surface of the filter screen 15. The filter screen 15 intercepts impurities and cleans them in real time. During this process, the filter screen 15, combined with the slide rail 12 and the fixing block 13, not only achieves a stable flue gas filtration function, but also facilitates the sliding disassembly of the fixing block 13 and the filter screen 15 via the slide rail 12, making it convenient for later maintenance and replacement. The self-cleaning mechanism, composed of the spiral impeller 16, the fixing plate 17 and the cleaning brush 18, is driven by the kinetic energy of the flue gas flow itself, without the need for additional power, to achieve real-time cleaning of the filter screen 15 and avoid the decrease in flue gas flow efficiency caused by impurities clogging the filter screen.

[0027] Furthermore, such as Figures 1-6As shown, a pair of sliding grooves 2 are symmetrically formed on the side wall of the fixed plate 17; the side wall of the sliding groove 2 is slidably connected to the same slider 21; a pair of levers 22 are symmetrically fixed to the side wall of the slider 21; an elastic rope 23 is fixed between the slider 21 and the spiral impeller 16; in use, when the spiral impeller 16 drives the fixed plate 17 to rotate, the sliding grooves 2 symmetrically formed on the side wall of the fixed plate 17 provide sliding space for the slider 21. Under the action of centrifugal force, the slider 21 will slide along the sliding groove 2 in a direction away from the spiral impeller 16, and the levers 22 can deflect the cleaning brush 18. The movement of the slide 21 shakes off the impurities adhering to the surface of the cleaning brush 18. When the flue gas flow decreases, the rotation speed of the spiral impeller 16 decreases, and the elastic rope 23 fixed between the slider 21 and the spiral impeller 16 generates a contraction force, pulling the slider 21 back to its original position along the slide groove 2. During this process, the sliding cooperation between the slide groove 2 and the slider 21 plays a self-cleaning role on the surface of the cleaning brush 18, reducing the accumulation of impurities and increasing the subsequent cleaning effect of the cleaning brush 18. At the same time, combined with the elasticity of the elastic rope 23, the slider 21 can automatically reset for reuse.

[0028] Furthermore, such as Figures 1-6 As shown, a magnetic block 3 is fixedly attached to the side wall of the spiral impeller 16; a plurality of elastic rods 31 are fixedly attached to the side wall of the filter screen plate 15; the elastic rods 31 are evenly distributed on the side wall of the filter screen plate 15 and have the same structure; a magnetic ball 32 is fixedly attached to the end of the elastic rod 31; in use, when the magnetic block 3 fixed to the side wall of the spiral impeller 16 rotates with the spiral impeller 16, it will generate a periodic repulsive force with the magnetic ball 32 at the end of the elastic rod 31 evenly distributed on the side wall of the filter screen plate 15. When the magnetic block 3 approaches the magnetic ball 32, the magnetic attraction pushes the magnetic ball 32 to cause the elastic rod 31 to bend and deform, causing the magnetic ball 32 to approach and impact the filter screen plate 15, and the attached impurities are shaken off by the impact vibration. When the magnetic block 3 moves away from the magnetic ball 32, the elastic restoring force of the elastic rod 31 causes the magnetic ball 32 to reset. During this process, the deformation and reset of the elastic rod 31 will cause the filter screen plate 15 to vibrate slightly. In this process, the magnetic effect of the magnetic block 3 and the magnetic ball 32 combined with the elasticity of the elastic rod 31 can make the filter screen plate 15 vibrate without additional power. The auxiliary cleaning brush 18 shakes off stubborn impurities on the surface of the filter screen, further improving the self-cleaning effect and preventing impurities from adhering and clogging the filter screen plate 15. The evenly distributed structure of the elastic rod 31 makes the vibration of the filter screen plate 15 more uniform, preventing excessive local vibration from damaging the filter screen plate 15 and extending the service life of the filter screen plate 15.

[0029] Furthermore, such as Figures 1-6As shown, multiple sliding cylinders 4 are fixedly connected to the side wall of the receiving pipe 11; the sliding cylinders 4 are evenly distributed on the side wall of the receiving pipe 11 and have the same structure; a spring 41 is fixedly connected to the inner side wall of the sliding cylinder 4; a sliding rod 42 is fixedly connected to the end of the spring 41; the sliding rod 42 and the sliding cylinder 4 are in sliding fit; a protective plate 43 is fixedly connected to the end of the sliding rod 42; in use, when the receiving pipe 11 is subjected to external impact, the external force first acts on the protective plate 43 fixed to the end of the sliding rod 42, the protective plate 43 transmits the external force to the sliding rod 42, and the sliding rod 42 slides inward along the sliding cylinder 4 and is compressed. Spring 41 absorbs impact energy through deformation, and then spring 41 elastically recovers to push slide bar 42 and protective plate 43 to reset. During this process, the buffer structure of protective plate 43, combined with slide bar 42, slide cylinder 4 and spring 41, can effectively absorb external impact force, prevent the bearing pipe 11 from being directly damaged by impact, and protect the filter screen plate 15 and spiral impeller 16 inside the bearing pipe 11. Multiple evenly distributed slide cylinders 4 and slide bars 42 can make the protective force more uniform, improve the overall impact resistance of bearing pipe 11, and adapt to the complex working environment of mold processing workshop.

[0030] Furthermore, such as Figures 1-6 As shown, the slide rod 42 has a groove 5 on its side wall; a plurality of elastic plates 51 are uniformly fixed to the side wall of the groove 5; in use, when the slide rod 42 slides along the slide cylinder 4, the plurality of elastic plates 51 uniformly fixed in the groove 5 on the side wall of the slide rod 42 will make contact friction with the inner side wall of the slide cylinder 4. During the process of the slide rod 42 compressing the spring 41, the elastic plates 51 are squeezed and deformed, further absorbing the kinetic energy generated by the impact. When the spring 41 pushes the slide rod 42 to reset, the elastic restoring force of the elastic plates 51 can assist the slide rod 42 to reset smoothly, avoiding the slide rod 42 from resetting too quickly and colliding with the end of the slide cylinder 4. During this process, the elastic plates 51 in the groove 5 can form a double buffer with the spring 41, further improving the impact resistance of the slide rod 42 and the protective plate 43, reducing the impact of external forces on the bearing pipe 11. The friction damping effect of the elastic plates 51 can make the slide rod 42 slide more smoothly, avoiding the slide rod 42 from jamming or violent shaking during the sliding process, and extending the service life of the slide rod 42 and the slide cylinder 4.

[0031] Furthermore, such as Figures 1-6As shown, a rubber sleeve 6 is fixed to the side wall of the magnetic ball 32. During use, the side wall of the magnetic ball 32, which is fixed to the end of the elastic rod 31, is wrapped with the rubber sleeve 6. When the magnetic ball 32 impacts the filter screen 15, the rubber sleeve 6 can isolate the magnetic ball 32 from direct contact with the filter screen 15, avoiding wear caused by the collision. At the same time, when the elastic rod 31 drives the magnetic ball 32 to vibrate, the rubber sleeve 6 can buffer the impact noise between the magnetic ball 32 and the filter screen 15, reducing noise generation. During this process, the rubber sleeve 6 can effectively protect the filter screen 15, avoiding surface wear caused by long-term collision, and improving the service life of the filter screen 15. The buffering and sound insulation effects of the rubber sleeve 6 can reduce collision noise during operation and improve the workshop working environment.

[0032] Working principle: In use, first, place the filter screen plate 15 and the spiral impeller 16 into the receiving pipe 11, insert the fixing block 13 into the slide rail 12, and use the friction between the rubber pad 14 and the slide rail 12 to fix the fixing block 13, thus realizing the installation and fixation of the filter screen plate 15 and the spiral impeller 16. Then, connect and fix the external pipe to the receiving pipe 11. The flue gas generated by the tempering furnace first enters the receiving pipe 11. The filter screen plate 15 forms a flue gas filtration channel, and large particulate impurities in the flue gas are intercepted and filtered by the filter screen plate 15. At the same time, during the flow of flue gas, it will drive the spiral impeller 16, which is rotated and connected to the side wall of the filter screen plate 15, to rotate. The symmetrical fixing plate 17 fixed to the side wall of the spiral impeller 16 rotates synchronously with the impeller. The side wall of the fixing plate 17 is evenly distributed Multiple cleaning brushes 18 of the cloth move relative to the surface of the filter screen 15, cleaning the impurities intercepted by the filter screen 15 in real time. During use, when the spiral impeller 16 drives the fixed plate 17 to rotate, the symmetrically opened grooves 2 on the side wall of the fixed plate 17 provide sliding space for the slider 21. Under centrifugal force, the slider 21 slides away from the spiral impeller 16 along the grooves 2. The paddle 22 can move the cleaning brushes 18, shaking off the impurities adhering to their surfaces. When the flue gas flow decreases, the speed of the spiral impeller 16 decreases, and the elastic rope 23 fixed between the slider 21 and the spiral impeller 16 generates a contraction force, pulling the slider 21 back to its original position along the grooves 2. During use, the magnetic block 3 fixed to the side wall of the spiral impeller 16 moves with the spiral impeller 16. 6. During rotation, the magnetic block 3 generates a periodic repulsive force with the magnetic balls 32 at the ends of the elastic rods 31 evenly distributed on the sidewall of the filter screen 15. When the magnetic block 3 approaches the magnetic balls 32, the magnetic attraction pushes the magnetic balls 32, causing the elastic rods 31 to bend and deform, making the magnetic balls 32 approach and impact the filter screen 15. The impact vibration shakes off the attached impurities. When the magnetic block 3 moves away from the magnetic balls 32, the elastic restoring force of the elastic rods 31 causes the magnetic balls 32 to return to their original position. During this process, the deformation and return of the elastic rods 31 will cause the filter screen 15 to vibrate slightly. In use, when the receiving pipe 11 is subjected to external impact, the external force first acts on the protective plate 43 fixed to the end of the sliding rod 42. The protective plate 43 transmits the external force to the sliding rod 42, and the sliding rod 42 slides inward along the sliding cylinder 4 and compresses the elastic rod. Spring 41 absorbs impact energy through deformation, and then elastically recovers to push slide rod 42 and protective plate 43 back to their original positions. During use, when slide rod 42 slides along slide cylinder 4, multiple elastic plates 51 uniformly fixed in the groove 5 on the side wall of slide rod 42 will contact and rub against the inner side wall of slide cylinder 4. During the compression of spring 41 by slide rod 42, the elastic plates 51 are compressed and deformed, further absorbing the kinetic energy generated by the impact. When spring 41 pushes slide rod 42 back to its original position, the elastic recovery force of the elastic plates 51 assists slide rod 42 in smoothly returning to its original position, preventing slide rod 42 from returning too quickly and colliding with the end of slide cylinder 4. During use, the side wall of the magnetic ball 32 fixed to the end of elastic rod 31 is wrapped with a rubber sleeve 6. When the magnetic ball 32 impacts the filter screen plate 15...The rubber sleeve 6 isolates the magnetic ball 32 from direct contact with the filter screen 15, preventing wear caused by collision. Simultaneously, when the elastic rod 31 drives the magnetic ball 32 to vibrate, the rubber sleeve 6 buffers the impact noise between the magnetic ball 32 and the filter screen 15, reducing noise generation.
