Abstract
Description
Technical Field
[0001] This utility model relates to the field of scrap iron recycling technology, and in particular to a crushing device for scrap iron recycling and processing. Background Technology
[0002] Scrap iron processing involves the scientific and rational processing of scrap iron, which can not only effectively reduce the mining of primary iron ore, reduce energy consumption and environmental pollution, but also provide high-quality raw materials for many industries. Among them, the crushing equipment for scrap iron recycling and processing is a device specifically designed to crush large pieces of scrap iron into smaller particles or fragments to facilitate subsequent transportation, smelting and reprocessing.
[0003] Existing technologies generate a large amount of metal powder during use. This metal powder is dispersed randomly with the airflow, reducing the recycling rate of resources. Furthermore, the large amount of metal powder floating in the air will cause serious pollution to the workshop environment and reduce air quality. If users are exposed to such an environment for a long time, their health will be threatened, and they will be prone to respiratory diseases. Moreover, this dust pollution may also cause safety hazards, such as dust explosions. Summary of the Invention
[0004] The technical problem to be solved by this utility model is that the existing technology does not have a structure to collect the metal powder generated during the processing of the device, which causes the metal powder to float in the air and harm the health of the user. To this end, we propose a crushing device for recycling and processing scrap iron.
[0005] To achieve the above objectives, this application adopts the following technical solution: a crushing device for scrap iron recycling and processing, comprising a first housing: a feed hopper is fixedly connected to the top of the first housing; a servo motor is installed on one side of the first housing; a crushing roller is installed at the output end of the servo motor; ventilation slots are provided at both ends inside the feed hopper; a flexible hose is installed inside the ventilation slots; a second housing is installed on one side of the first housing; one end of the second housing is fixedly connected to one end of the flexible hose; a dust extraction fan is installed at both ends of the second housing; mounting slots are provided at both ends inside the second housing; an exhaust fan is installed at the bottom end of the mounting slots; filter screens are installed at both ends of the bottom of the second housing; a mounting bracket is slidably connected to the inner wall of the mounting slot; an extension block is fixedly connected to one side of the mounting bracket; two clamping blocks are rotatably connected to both ends of one side of the second housing via a rotating shaft; and an air filter element body is installed inside the mounting bracket.
[0006] Preferably, a groove is provided on one side of the extension block, and a sliding buckle is slidably connected to the inner wall of the groove, and the inner wall of the sliding buckle is slidably connected to the surface of the clamping block.
[0007] Preferably, a slide rod is installed inside the slide groove, and one end of the slide rod passes through one side of the slide buckle and is fixedly connected to one side of the inner wall of the slide groove.
[0008] Preferably, a spring is fixedly connected to one side of the sliding buckle, and the other end of the spring is fixedly connected to one side of the inner wall of the sliding groove.
[0009] Preferably, a screen is installed at one end of the inner wall of the ventilation groove.
[0010] Preferably, guide rails are fixedly connected to both sides of the inner wall of the mounting groove, and sliders are slidably connected to the inner wall of the guide rails. One side of the slider is fixedly connected to one end of the surface of the mounting bracket.
[0011] Preferably, guide rails are fixedly connected to both sides of the inner wall of the mounting groove, and sliders are slidably connected to the inner wall of the guide rails. One side of the slider is fixedly connected to one end of the surface of the mounting bracket.
[0012] Technical effects and advantages of this utility model:
[0013] In this invention, the user filters metal powder through the air filter body inside the mounting bracket inside the second housing, and then the powder is discharged through the filter screen by the exhaust fan at the bottom of the second housing. When the air filter body needs to be replaced, the user rotates the clamping block through the shaft, causing one end of the clamping block to disengage from the inner wall of the extension block. After the mounting bracket contacts and connects with the second housing, the user pulls the mounting bracket out along the inner wall of the mounting groove, and then takes out the air filter body for replacement. The collection of metal powder by the air filter body avoids the direct emission of metal powder into the air, which would not only waste resources but also pollute the environment and may even pose a potential hazard to the health of the operator.

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0023] Reference Figures 1-6As shown, this utility model provides a technical solution: a crushing device for scrap iron recycling and processing, including a first housing 1; a feed hopper 2 is fixedly connected to the top of the first housing 1; a servo motor 3 is installed on one side of the first housing 1; a crushing roller 4 is installed at the output end of the servo motor 3; ventilation grooves 5 are opened at both ends inside the feed hopper 2; a flexible hose 6 is installed inside the ventilation groove 5; a second housing 7 is installed on one side of the first housing 1; one end of the second housing 7 is fixedly connected to one end of the flexible hose 6; dust extraction fans 8 are installed at both ends of the second housing 7; and dust extraction fans 8 are installed inside the second housing 7. Both ends of the first housing 7 have mounting slots 9, and an exhaust fan 10 is installed at the bottom of the mounting slot 9. Filter screens 11 are installed at both ends of the bottom of the second housing 7. A mounting bracket 12 is slidably connected to the inner wall of the mounting slot 9. An extension block 13 is fixedly connected to one side of the mounting bracket 12. Two clamping blocks 14 are rotatably connected to both ends of one side of the second housing 7 via a rotating shaft. An air filter element body 15 is installed inside the mounting bracket 12. When the user is ready to process scrap iron, the servo motor 3 is driven by the control panel on one side of the first housing 1, which in turn drives the crushing roller 4. When scrap iron is poured into the interior of the first housing 1 along the inclined surface of the feed hopper 2, it is crushed by the crushing rollers 4 at both ends of the first housing 1. During this crushing process, a large amount of metal powder is generated. At this time, the dust extraction fans 8 at both ends of the second housing 7 extract the metal powder generated during processing inside the first housing 1 through the ventilation slots 5 opened at both ends of the feed hopper 2 via hoses 6. The air from inside the second housing 7 passes through the air filter body 15 inside the mounting bracket 12 to filter the metal powder, and then passes through the filter screen 11 by the exhaust fan 10 at the bottom of the second housing 7. When the air filter body 15 needs to be replaced, the user rotates the clamping block 14 through the rotating shaft, so that one end of the clamping block 14 is disengaged from the inner wall of the extension block 13, and the mounting bracket 12 is made to contact and connect with the second housing 7. The user then pulls out the mounting bracket 12 along the inner wall of the mounting groove 9 and takes out the air filter body 15 for replacement. The collection of metal powder by the air filter body 15 avoids the direct emission of metal powder into the air, which would not only waste resources but also pollute the environment and may even pose a potential hazard to the health of the operators.
[0024] Reference Figure 5 and Figure 6As shown in this embodiment: a groove 16 is provided on one side of the extension block 13, and a sliding buckle 17 is slidably connected to the inner wall of the groove 16. The inner wall of the sliding buckle 17 is slidably connected to the surface of the clamping block 14. When the user inserts the clamping block 14 into the inner wall of the extension block 13, the sliding buckle 17 is moved along the inner wall of the groove 16, so that the sliding buckle 17 restricts the movement space on both sides of the clamping block 14, preventing it from unfolding to both sides. By restricting the clamping block 14 with the sliding buckle 17, the stability of the connection between the mounting bracket 12 and the second housing 7 is further enhanced, ensuring that the mounting bracket 12 will not detach from the second housing 7 due to vibration or other reasons during the operation of the device, thereby ensuring the continuous and stable operation of the metal powder filtration.
[0025] Reference Figure 5 and Figure 6 As shown in this embodiment: a slide rod 18 is installed inside the slide groove 16. One end of the slide rod 18 passes through one side of the slide buckle 17 and is fixedly connected to one side of the inner wall of the slide groove 16. When the user moves the slide buckle 17 through the surface of the slide rod 18 on the inner wall of the slide groove 16, the movement trajectory of the slide buckle 17 becomes more stable.
[0026] Reference Figure 5 and Figure 6 As shown in this embodiment: a spring 19 is fixedly connected to one side of the sliding buckle 17, and the other end of the spring 19 is fixedly connected to one side of the inner wall of the slide groove 16. When the user moves the sliding buckle 17 along the inner wall of the slide groove 16, the sliding buckle 17 squeezes the spring 19, causing the spring 19 to store and compress. When the user is ready to move the sliding buckle 17 back to its original position, the user releases the sliding buckle 17, causing the spring 19 to release and rebound, pushing the sliding buckle 17 back to its original position automatically. The operation steps of the device are simplified by the spring 19.
[0027] Reference Figure 1 and Figure 4 As shown in this embodiment: a screen 20 is installed at one end of the inner wall of the ventilation groove 5. When the user starts the equipment, the dust extraction fan 8 is made to extract dust from the inside of the first housing 1 through the screen 20, which prevents large metal particles from splashing and damaging the dust extraction fan 8, extends the service life of the dust extraction fan 8, and thus ensures the stable dust extraction effect of the entire crushing device during operation.
[0028] Reference Figure 4 and Figure 5 As shown in this embodiment: guide rails 22 are fixedly connected to both sides of the inner wall of the mounting groove 9, and sliders 23 are slidably connected to the inner wall of the guide rails 22. One side of the slider 23 is fixedly connected to one end of the surface of the mounting bracket 12. When the user installs the air filter body 15 into the interior of the mounting bracket 12 along the limiting rod 21, the limiting rod 21 limits the air filter body 15 to prevent the air filter body 15 from shaking or shifting during operation.
[0029] Reference Figure 4 and Figure 5 As shown in this embodiment: guide rails 22 are fixedly connected to both sides of the inner wall of the mounting groove 9, and sliders 23 are slidably connected to the inner wall of the guide rails 22. One side of the slider 23 is fixedly connected to one end of the surface of the mounting bracket 12. When the user moves the mounting bracket 12 along the inner wall of the guide rails 22 through the sliders 23 at both ends, the vibration generated when the mounting bracket 12 moves further ensures the stability of the equipment operation and reduces the risk of equipment wear and failure caused by vibration.
[0030] Working principle:
[0031] Step one: When the user prepares to process scrap iron, they first drive the servo motor 3 via the control panel on one side of the first housing 1. The servo motor 3 then drives the crushing roller 4 to rotate. The user pours the scrap iron into the interior of the first housing 1 along the inclined surface of the feed hopper 2. The scrap iron is crushed by the crushing rollers 4 at both ends inside the first housing 1. During the crushing process, a large amount of metal powder is generated. At this time, the dust extraction fans 8 at both ends of the second housing 7 enter the ventilation slots 5 at both ends of the feed hopper 2 through the hoses 6 to extract the metal powder generated during processing inside the first housing 1. As air enters the second housing 7, it is filtered by the air filter body 15 inside the mounting bracket 12. Metal powder is trapped and collected by the air filter body 15. The filtered air is then discharged through the filter screen 11 by the exhaust fan 10 at the bottom of the second housing 7. When the air filter body 15 needs to be replaced, the user first rotates the clamp 14 through the shaft to disengage one end of the clamp 14 from the inner wall of the extension block 13. Then, the mounting bracket 12 is brought into contact with the second housing 7. Next, the mounting bracket 12 is pulled out along the inner wall of the mounting groove 9. Finally, the air filter body 15 is taken out for replacement.
[0032] Step two: After the user inserts the clamping block 14 into the inner wall of the extension block 13, the sliding buckle 17 is then moved along the inner wall of the slide groove 16. Guided by the surface of the slide rod 18, the movement trajectory of the sliding buckle 17 is made more stable. During this process, the sliding buckle 17 squeezes the spring 19, causing the spring 19 to store and compress, thereby restricting the movement space on both sides of the clamping block 14, preventing it from unfolding to the sides. By restricting the clamping block 14 with the sliding buckle 17, the stability of the connection between the mounting bracket 12 and the second housing 7 is further enhanced, ensuring that the mounting bracket 12 will not detach from the second housing 7 due to vibration or other reasons during the operation of the device, thus ensuring the continuous and stable operation of the metal powder filtration. When the user is ready to move the sliding buckle 17 back to its original position, simply release the sliding buckle 17, and the spring 19 will release and rebound to push the sliding buckle 17 back to its original position automatically.
[0033] Step 3: When the user starts the equipment, the screen 20 plays a role. When the dust extraction fan 8 extracts dust from the inside of the first housing 1, it effectively prevents large metal particles from splashing and damaging the dust extraction fan 8, thereby extending the service life of the dust extraction fan 8 and ensuring the stable dust extraction effect of the entire crushing device during operation. When the user installs the air filter body 15 into the mounting bracket 12 along the limiting rod 21, the limiting rod 21 limits the air filter body 15 to prevent it from shaking or shifting during operation. When the user moves the mounting bracket 12 along the inner wall of the guide rail 22 via the sliders 23 at both ends, the cooperation between the sliders 23 and the guide rail 22 can absorb the vibration generated when the mounting bracket 12 moves.
[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
