Description
Technical Field
[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a rapid dust removal equipment for limestone processing. Background Technology
[0002] The generation and spread of lime powder are common problems during limestone processing. If lime powder is discharged directly into the environment without effective treatment, it will not only cause air pollution and affect the surrounding ecological environment, but may also pose a potential threat to the health of operators.
[0003] Existing dust collection equipment for limestone processing mostly employs methods such as bag filters. While bag filters can filter some dust, the bags are prone to clogging after prolonged use, leading to decreased dust collection efficiency. Frequent bag replacements increase operating costs and maintenance difficulty, and the cleaning process is cumbersome, difficult to thoroughly remove dust, and prone to secondary dust re-entrainment, further affecting dust collection effectiveness. Furthermore, existing equipment typically collects lime powder in a loose state, which not only occupies a large space but also easily spills during cleaning, recycling, storage, and transportation, hindering subsequent processing and utilization. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a rapid dust removal device for limestone processing, which solves some of the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a rapid dust removal device for limestone processing, including a dust removal table, a ventilation hood fixedly installed at the upper end of the dust removal table, and ion air bars evenly distributed on the inner top wall of the ventilation hood near the left side. A sliding cavity is provided in the middle of the interior of the dust removal table, and a fixed platform is fixedly installed near the upper side inside the sliding cavity. Slots with staggered distribution are provided on the fixed platform. A lifting plate is slidably installed inside the sliding cavity at the lower side of the fixed platform. Metal rods with staggered distribution are fixedly installed at the upper end of the lifting plate. The metal rods pass through and are slidably connected inside the slots. An electromagnetic plate is installed between the upper ends of the metal rods. The size of the electromagnetic plate is adapted to the fixed platform.
[0006] Furthermore, a positive high-voltage power supply is installed at the upper end of the ventilation hood near the left side, and the positive high-voltage power supply is electrically connected to the ion fan bar.
[0007] Furthermore, the lifting plate is fixedly connected to the middle of both its front and rear ends, and the dust removal platform is provided with lifting grooves in the middle of the sliding cavity at both its front and rear ends, with the fixing members passing through and slidably connected inside the lifting grooves.
[0008] Furthermore, electric push rods are fixedly installed at both the front and rear ends of the dust removal table, and the lower output end of the electric push rod is fixedly connected to the fixing component.
[0009] Furthermore, the dust removal table has a transverse cavity located on the upper side of the fixed platform. Inside the transverse cavity, a material picking frame is slidably installed at the upper end of the fixed platform. The inner wall of the material picking frame matches the fixed platform, and a handle is fixedly connected to the right end of the material picking frame.
[0010] The advantages of this utility model are as follows: A positive high-voltage power supply powers the ionizing air bars, charging the lime powder. Simultaneously, multiple staggered metal bars connected to a negative high-voltage power supply create an electrostatic field. This dual action precisely adsorbs the charged lime powder, effectively stripping it from the airflow. Compared to traditional single dust removal methods, this design improves dust removal efficiency, rapidly reduces lime powder concentration in the work area, improves the working environment, reduces dust hazards to equipment and personnel, and ensures the safety and stability of the production process. Furthermore, an electric push rod lowers the metal bars and disconnects the power supply. After scraping off the attached lime powder onto a fixed platform, a strong magnetic field is generated by passing a strong current through an electromagnetic plate to hold the metal bars in place. During descent, the lime powder is compressed into a stable block structure. This design avoids loose accumulation of lime powder, reduces secondary dusting during cleaning, and lowers cleaning difficulty and cost. At the same time, the compacted lime powder is easier to store and transport to the next process, improving the recycling rate of lime powder and achieving effective resource integration and utilization.

[0013] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figures 1-3 A rapid dust removal device for limestone processing includes a dust removal table 1. A ventilation hood 2 is fixedly installed on the upper end of the dust removal table 1. Ionizing air bars 3 are evenly distributed and fixedly installed on the inner top wall of the ventilation hood 2 near the left side. A sliding cavity 5 is provided in the middle of the interior of the dust removal table 1. A fixed platform 6 is fixedly installed near the upper side inside the sliding cavity 5. Slots 7 are provided on the fixed platform 6. A lifting plate 8 is slidably installed inside the sliding cavity 5 at the lower side of the fixed platform 6. Metal rods 9 are fixedly installed at the upper end of the lifting plate 8, passing through and slidably connected to the inside of the slots 7. Electromagnetic plates 10 are installed between the upper ends of the metal rods 9. The size of the electromagnetic plates 10 is adapted to the fixed platform 6. A ventilation duct structure is formed by the enclosed space between the dust removal table 1 and the ventilation hood 2. When the airflow carrying lime powder passes through, a positive high-voltage power supply 4 powers the ionizing air bars 3, energizing the lime powder. Simultaneously, multiple sets of staggered... The metal rods 9, distributed in a specific position, are connected to a negative high-voltage power supply to form an electrostatic field that adsorbs charged lime powder, thereby separating the lime powder from the airflow and achieving a dust removal effect. By opening the electric push rod 13, its output end drives the fixing part 11 to descend, which in turn drives the lifting plate 8 to descend. The descent of the lifting plate 8 drives the metal rods 9 to descend, and at the same time, the power supply to the metal rods 9 is disconnected, which allows the lime powder attached to the metal rods 9 to be scraped off and collected at the upper end of the fixed platform 6. This process is repeated. When enough lime powder has been collected, when the metal rods 9 are driven down again by the lifting plate 8, a strong current is passed through the electromagnetic plate 10, which generates a strong magnetic field that firmly attracts the metal rods 9. As the metal rods 9 drive the electromagnetic plate 10 to descend and approach the fixed platform 6, the electromagnetic plate 10 can squeeze the lime powder collected on the fixed platform 6, thereby compacting the lime powder and forming a stable block structure.
[0015] Please see Figures 1-3A positive high-voltage power supply 4 is installed near the left side of the upper end of the ventilation hood 2. The positive high-voltage power supply 4 is electrically connected to the ion air bar 3. Fixing components 11 are fixedly connected to the middle of the front and rear ends of the lifting plate 8. Lifting grooves 12 are provided at the middle of the sliding cavity 5 at the front and rear ends of the dust removal table 1. The fixing components 11 pass through and slide inside the lifting grooves 12. Electric push rods 13 are fixedly installed at the front and rear ends of the dust removal table 1. The lower output end of the electric push rod 13 is fixedly connected to the fixing component 11. A transverse cavity 14 is provided inside the dust removal table 1 on the upper side of the fixed platform 6. The transverse cavity 14 is located inside the fixed platform 6. A material picking frame 15 is slidably installed at the upper end of the fixed platform 6. The inner wall of the material picking frame 15 matches the fixed platform 6. A handle 16 is fixedly connected to the right end of the material picking frame 15. Finally, after the electromagnetic plate 10 is de-energized and the metal rod 9 is disengaged from it and descends into the slot 7, the material picking frame 15 is moved outward by pulling the handle 16. Thus, the lime powder pressed into blocks is brought out from the upper end of the fixed platform 6 through the material picking frame 15. This not only completes the dust removal operation, but also keeps the collected lime powder in a relatively stable form, which is not only convenient for cleaning and recycling, but also convenient for storage or transfer to the next process.
[0016] Working Principle: In operation, the enclosed space between the dust collection table 1 and the ventilation hood 2 forms a ventilation duct structure. When the airflow carrying lime powder passes through, the positive high-voltage power supply 4 powers the ionizing air bar 3, charging the lime powder. Simultaneously, multiple sets of staggered metal bars 9 are connected to a negative high-voltage power supply, forming an electrostatic field that adsorbs the charged lime powder, thus peeling the lime powder off from the airflow and achieving the dust removal effect. By opening the electric push rod 13, its output end drives the fixing part 11 to descend, thereby driving the lifting plate 8 to descend. The descent of the lifting plate 8 drives the metal bars 9 to descend, and at the same time, the power supply to the metal bars 9 is disconnected, allowing the lime powder adhering to the metal bars 9 to be scraped off and collected at the top of the fixing table 6. This process is repeated until enough lime powder is collected, and the metal bars 9 are driven down again by the lifting plate 8. By passing a strong current through the electromagnetic plate 10, a strong magnetic field is generated, which firmly attracts the metal rod 9. As the metal rod 9 lowers the electromagnetic plate 10 closer to the fixed platform 6, the electromagnetic plate 10 can compress the lime powder collected on the fixed platform 6. This compression compacts the lime powder into a stable block structure. Finally, by de-energizing the electromagnetic plate 10 and causing the metal rod 9 to detach and descend into the slot 7, the handle 16 is pulled to move the material picking frame 15 outward. The material picking frame 15 then carries the compressed lime powder out from the upper surface of the fixed platform 6. This not only completes the dust removal operation but also maintains the collected lime powder in a relatively stable form, making it easy to clean, recycle, store, or transfer to the next process.
