Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust treatment technology, specifically a dust treatment device for non-ferrous metal alloy manufacturing. Background Technology
[0002] The production and manufacturing of non-ferrous metal alloys generates a lot of smoke and dust, which can seriously pollute the environmental quality of the processing workshop and endanger the health of the operators. Therefore, in order to ensure the air quality of the non-ferrous metal alloy processing workshop, dust collectors are installed in the processing workshop to filter the dust in the air.
[0003] However, when using baghouse dust collectors for dust removal in non-ferrous metal alloy processing workshops, the dust generated by metal alloy processing is relatively hard. Therefore, when it enters the dust collector, it will first come into contact with the bottom of the filter bag, which will accelerate the wear of the bottom of the filter bag, resulting in holes or breakage at the bottom of the filter bag, affecting the dust removal efficiency and reducing the service life of the filter bag. Utility Model Content
[0004] The purpose of this utility model is to provide a dust treatment device for non-ferrous metal alloy manufacturing, in order to solve the problem mentioned in the background art that when using a bag filter to remove dust in a non-ferrous metal alloy processing workshop, the dust generated by metal alloy processing is relatively hard. Therefore, when the dust enters the dust collector and comes into contact with the filter bag, the pressure angle will accelerate the wear of the bottom of the filter bag, which will easily cause damage to the bottom of the filter bag, affecting the dust removal efficiency and reducing the service life of the filter bag.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust treatment device for non-ferrous metal alloy manufacturing, comprising a dust collector, wherein the dust collector is provided with a protective component for protecting the filter bag, the protective component comprising multiple ring frames disposed inside the dust collector, each ring frame having a conical head at its bottom, a through groove inside the conical head, and sliding grooves on the outer walls at both ends of each ring frame, wherein a filter bag is disposed outside the ring frames, and extension plates are disposed at both ends of the filter bag, with sliders disposed on the inner side of the extension plates; The ring frame has multiple supports inside, and multiple slots are provided on both sides of each support. Each slot has a retaining spring on its inner wall and a protrusion inside the slot.
[0006] Preferably, the plurality of the ring frame arrays are distributed inside the dust collector, and the ring frame has a double-layer structure, consisting of an inner ring and an outer ring, with a hollow structure between the inner ring and the outer ring.
[0007] Preferably, the conical head is connected to the bottom of the ring frame, and the through groove inside the conical head communicates with the hollow area inside the ring frame, and a mesh plate is installed on the inner wall of the through groove.
[0008] Preferably, the filter bag has a double-layer structure and is layered and fitted on the outer ring of the ring frame. One end of the extension plate is connected to the end of the filter bag by bolts, and the other end extends to the sliding groove area on the outer wall of the ring frame. One end of the slider is connected to the inner side of the extension plate, and the other end extends into the sliding groove and is slidably connected to the inner wall of the sliding groove.
[0009] Preferably, the plurality of supports are arranged in a ring inside the ring frame, and the ends of the supports are connected to the outer wall of the ring frame, and the two sides of the supports abut against the surface of the filter bag outside the ring frame.
[0010] Preferably, the plurality of the hole and groove arrays are distributed on both sides of the bracket, one end of the protrusion is located in the hole and groove and is slidably connected to the inner wall of the hole and groove, and the other end is a conical structure that extends to the outside. The retaining spring is located on the inner wall of the hole and groove and abuts against the protrusion.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By designing the annular fixing frame for installing filter bags inside the baghouse dust collector as a double-layer structure, two layers of filter bags can be installed, improving the dust removal effect. Furthermore, a conical head is added to the bottom of the annular fixing frame. The angle of the conical head can guide the air, and the mesh plate in the through groove inside the conical head can cut the air and disperse the airflow, reducing the pressure when the airflow comes into contact with the filter bag, thereby reducing wear on the filter bag and increasing its service life.
[0012] 2. By setting a support inside the annular fixed frame, and installing multiple retractable sliding protrusions on both sides of the support, the conical ends of the protrusions abut against the surface of the filter bag outside the annular fixed frame. The filter bag can be driven to rotate around the annular frame by the sliders at both ends of the filter bag. During the rotation, the protrusions extending from the outer wall of the support contact the filter bag, causing it to shake and rub off the dust on the filter bag, reducing the burden on the filter bag and ensuring the dust removal effect of the filter bag.
[0013] This invention improves dust removal efficiency by designing the filter bag with a double-layer structure. It also guides and cuts the air as it approaches the filter bag, thereby reducing the pressure when the airflow comes into contact with the filter bag and reducing wear on the filter bag. At the same time, shaking the filter bag can help clean the attached dust, ensuring the filter bag's performance. Attached Figure Description

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.
[0017] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.
[0018] Please see Figures 1-4 A dust treatment device for non-ferrous metal alloy manufacturing includes a dust collector 1. The dust collector 1 has a protective assembly inside for protecting filter bags. The protective assembly includes multiple ring frames 2 disposed inside the dust collector 1. The ring frames 2 have a double-layer structure, allowing for double-layer installation of filter bags 5. The double-layer structure of the filter bags 5 increases the dust contact area and contact time, thereby improving dust removal efficiency. Each ring frame 2 has a conical head 3 at its bottom. The conical head 3 guides the angle at which air approaches the ring frame 2 and filter bags 5 from the bottom. The conical head 3 has a through groove 301 inside, allowing the conical head 3 to communicate with the inside of the ring frame 2, and allowing air to pass through. When the filter bag 5 enters the through groove 301, the mesh plate installed in the through groove 301 can cut the air, thereby dispersing the airflow and reducing the pressure when the airflow comes into contact with the filter bag 5. Multiple ring frames 2 are provided with sliding grooves 4 on the outer walls at both ends. Filter bags 5 are provided on the outside of the ring frames 2. Filter bags 5 can adsorb dust in the air to achieve dust removal effect. Extension plates 501 are provided at both ends of the filter bags 5. Extension plates 501 are wrapped around the sliding grooves 4 on the outer wall of the ring frame 2. A slider 502 is provided on the inner side of the extension plate 501. One end of the slider 502 is embedded in the sliding groove 4 on the outer wall of the ring frame 2 and can slide in the sliding groove 4 through electronic control, thereby driving the filter bag 5 to rotate around the ring frame 2.
[0019] Multiple ring frames 2 are arrayed inside the dust collector 1. The ring frame 2 has a double-layer structure, consisting of an inner ring and an outer ring, with a hollow structure between the inner and outer rings. The conical head 3 is connected to the bottom of the ring frame 2, and the through groove 301 inside the conical head 3 communicates with the hollow area inside the ring frame 2. A mesh plate is installed on the inner wall of the through groove 301. The filter bag 5 has a double-layer structure and is layered and fitted on the outside of the inner and outer rings of the ring frame 2. One end of the extension plate 501 is connected to the end of the filter bag 5 by bolts, and the other end extends to the area of the slide groove 4 on the outer wall of the ring frame 2. One end of the slider 502 is connected to the inner side of the extension plate 501, and the other end extends into the slide groove 4 and slides in connection with the inner wall of the slide groove 4.
[0020] Specifically: During use, one end of the slider 502 on the inner side of the extension plate 501 is embedded into the groove 4 on the outer wall of the ring frame 2, thereby wrapping the filter bag 5 around the outside of the ring frame 2. Through the double-layer structure of the ring frame 2, the filter bags 5 can be stacked during installation, thereby increasing the air contact area and contact time, improving the efficiency of the filter bags 5 in capturing dust in the air and improving the dust removal effect. When the air approaches from the bottom of the filter bag 5, it can be guided and diffused through the conical head 3 at the bottom of the ring frame 2. The air can also enter the ring frame 2 through the through groove 301 inside the conical head 3. The mesh plate inside the ring frame 2 cuts the air, causing the airflow to be divided into multiple streams that contact the filter bag 5, dispersing the air pressure, reducing the pressure when in contact with the filter bag 5, reducing wear on the filter bag 5, and increasing the service life of the filter bag 5.
[0021] Please see Figure 2 and Figure 3 The ring frame 2 has multiple supports 6 inside, which can position the structure and angle of the ring frame 2. Multiple slots 7 are provided on both sides of the multiple supports 6 to accommodate the protrusions 8 and to position the angle of the protrusions 8 when they slide. The inner wall of the multiple slots 7 is provided with snap rings 701 to support the protrusions 8 in the slots 7 and push the protrusions 8 to extend outward. The protrusions 8 are provided inside the slots 7, and the conical structure on one side of the protrusions 8 can contact the surface of the filter bag 5.
[0022] Multiple supports 6 are arranged in a ring inside the ring frame 2, and the ends of the supports 6 are connected to the outer wall of the ring frame 2. The two sides of the supports 6 abut against the surface of the filter bag 5 outside the ring frame 2. Multiple slots 7 are arranged in an array on both sides of the supports 6. One end of the protrusion 8 is located in the slot 7 and is slidably connected to the inner wall of the slot 7. The other end is a conical structure and extends to the outside. The retaining spring 701 is located on the inner wall of the slot 7 and abuts against the protrusion 8.
[0023] Specifically: During the dust removal process using filter bag 5, the slider 502 is moved in the groove 4 on the outer wall of the ring frame 2 by electronic control, thereby driving the filter bag 5 to rotate. At the same time as the rotation, the protrusion 8 extending from the outer wall of the support 6 contacts the surface of the filter bag 5. Therefore, the filter bag 5 can rub against the surface of the filter bag 5 when it rotates. The vibration and shaking generated by the friction can shake off the dust attached to the filter bag 5, reduce the burden on the filter bag 5, and ensure the effectiveness of the filter bag 5.
