Technical Field
[0001] This application relates to the technical field of dust collection devices, and in particular to an electrostatic collection device for polishing dust. Background Technology
[0002] Polishing is an important step in the granite processing. Polishing granite generates a large amount of fine dust, which not only harms the health of workers but also pollutes the environment. Therefore, it is necessary to collect the dust during the polishing process to prevent the dust generated from polishing from affecting the construction environment.
[0003] The existing publication number CN222493775U, entitled "A Precious Metal Jewelry Polishing Dust Recycling Machine," belongs to the field of jewelry processing technology and solves the problem of impurities in the dust collected by existing recycling devices. It includes an isolation cover and a dust collection assembly. The isolation cover is installed on the worktable of a cloth wheel polishing machine. Symmetrically arranged operating channels for hand passage are opened on the front of the isolation cover. A cloth cover is connected to the outer perimeter of the operating channels, and an elastic ring is connected to the end of the cloth cover away from the operating channels. An inclined air collection pipe is provided on the worktable below the cloth wheel. The air inlet of the air collection pipe faces directly below the cloth wheel, and a sieve plate is threadedly connected to the air inlet of the air collection pipe. The top surface of the sieve plate has multiple sieve holes. The air outlet of the air collection pipe is connected to the dust collection assembly. This jewelry polishing dust recycling machine can prevent other impurities from mixing into the polishing dust, thus facilitating the subsequent separation and recycling of the polishing dust.
[0004] Regarding the aforementioned technologies, the inventors discovered that during dust collection, a suction fan is used to introduce external dust into a cloth bag for filtration and removal. However, the cloth bag can only filter and remove large dust particles, leaving small dust particles in the exhaust air. This results in incomplete dust removal and affects the cleanliness of the collected dust. Utility Model Content
[0005] In order to overcome the problem that existing filter bags can only filter and remove large dust particles, leaving small dust particles in the exhaust air, resulting in incomplete dust removal and affecting the cleanliness of dust collection and removal in the air, this application provides an electrostatic collection device for polishing dust.
[0006] The electrostatic collection device for polishing dust provided in this application adopts the following technical solution: A polishing dust electrostatic collection device includes a clamping component, a dust collection hood, a filter cartridge, and a dust removal component. The clamping component includes a clamping seat and a sliding frame. The clamping seat is fixedly assembled by locking bolts, and screw holes are vertically fixed on the side end face of the clamping seat. A sliding frame is horizontally fixed on the top surface of the screw holes on one side of the clamping seat, and a dust collection hood is slidably assembled on the sliding frame. The bottom surface of the dust collection hood is open, and a suction pipe is connected and fixed on the top surface of the dust collection hood. The other end of the suction pipe is connected and assembled with the filter cartridge, and a mesh cylinder is vertically fixed inside the filter cartridge. A cloth sleeve is fitted and fixed on the inner wall of the mesh cylinder. The dust removal component includes a dust collection box. The top surface of the dust collection box is connected and assembled with the bottom end of the filter cartridge, and a suction pump is connected and fixed on the bottom surface of the dust collection box. One side of the dust collection box is open, and a pull-out plate is inserted into the opening of the dust collection box. A discharge electrode is horizontally fixed on the vertical end face of the inner side of the pull-out plate, and multiple dust collection plates are horizontally and vertically inserted into the discharge electrode.
[0007] By adopting the above technical solution, when grinding and polishing granite, the granite is placed on the top surface of the clamping seat of the clamping component. During grinding and polishing, the dust collection hood is pushed to slide on the sliding frame, so that the dust collection hood is above the granite. During polishing, the suction pump at the bottom of the dust collection box is activated, which drives the dust generated during granite polishing into the dust collection hood. The dust-laden air is guided into the filter cartridge through the suction pipe. After the dust-laden air is filtered by the cloth sleeve to remove large particles of impurities, the air containing fine dust particles is guided into the dust collection component. When the air flows in the dust collection box, the air contacts the metal dust collection plate and generates an electrostatic field through the high-voltage power supply, which is used to collect the fine dust particles in the settled air. Then the air is discharged through the suction pump. Therefore, the dust generated during polishing is filtered and removed by the cloth sleeve in the filter cartridge, and the fine dust particles in the air are further removed by the electrostatic dust collection generated by the dust collection component, thus ensuring the cleanliness of the working environment during granite grinding and polishing.
[0008] Optionally, a screw hole is provided through the top of the screw hole frame with a horizontal thread, and a pressing screw is assembled through the screw hole of the screw hole frame with a horizontal thread.
[0009] By adopting the above technical solution, in order to ensure the stability of the granite in the clamping seat during polishing, the extrusion screw in the screw hole of the screw hole frame is rotated, and the granite is extruded and kept stable in the clamping seat during polishing.
[0010] Optionally, a sliding bracket is vertically fixed on the rear vertical end face of the dust collection cover, and the bottom of the sliding bracket is horizontally slidably assembled on the slide frame.
[0011] By adopting the above technical solution, the sliding bracket on the dust collection hood slides horizontally on the sliding frame and slides laterally to reach the top of the granite.
[0012] Optionally, the filter cartridge has internal threads on both the upper and lower sides of its inner wall, and the other end of the suction tube and the top of the dust collection box are connected and fixed with screw caps, and the screw caps on the suction tube and the dust collection box are threaded onto the internal threads of the filter cartridge.
[0013] By adopting the above technical solution, when the dust collection hood, filter cartridge and dust removal component are assembled and connected, the suction pipe and the screw cap on the dust collection box are assembled onto the internal thread of the filter cartridge, thus completing the assembly and connection of the dust collection hood, filter cartridge and dust removal component.
[0014] Optionally, a rotating frame is vertically fixed in the screw cover of the dust collector box, and a rotating motor is vertically fixed on the bottom surface of the rotating frame. A scraper is vertically rotatably connected to the top surface of the rotating frame, and the scraper penetrates the bottom surface of the cloth cover and is inserted into the inside of the cloth cover.
[0015] By adopting the above technical solution, in order to ensure the effectiveness of the cloth cover filtration, the rotating motor on the bottom surface of the rotating frame is started to drive the scraper to rotate. The scraper presses against the inner wall of the cloth cover to scrape off the dust and impurities on the inner wall of the cloth cover, thus ensuring the effectiveness of the cloth cover filtration.
[0016] Optionally, brushes are evenly fixed on the vertical end face of the scraper.
[0017] By adopting the above technical solution, the brush fixed on the scraper removes dust and impurities from the inner wall of the cloth cover, ensuring the effectiveness of the cloth cover filtration.
[0018] Optionally, a power supply is fixed on the outer wall of the dust collection plate, and the power output terminal is electrically connected to the discharge electrode through a wire.
[0019] By adopting the above technical solution, an electrostatic field is generated by a power source to collect settled dust.

[0021] By adopting the above technical solution, a controller is used to adjust the output voltage and current of the high-voltage power supply to adapt to working conditions with different dust concentrations.
[0022] In summary, this application includes at least one of the following beneficial technical effects: During the grinding and polishing of granite, the granite is placed on the top surface of the clamping seat of the clamping component. During grinding and polishing, the dust collection hood is pushed to slide on the sliding frame, so that the dust collection hood is positioned above the granite. During polishing, the suction pump at the bottom of the dust collection box is activated, which drives the dust generated during granite polishing into the dust collection hood. The dust-laden air is guided into the filter cartridge through the suction pipe. After the dust-laden air is filtered by the cloth sleeve to remove large particles of impurities, the air containing fine dust particles is guided into the dust collection component. When the air flows in the dust collection box, the air contacts the metal dust collection plate and generates an electrostatic field through a high-voltage power supply, which is used to collect the fine dust particles in the settled air. Then the air is discharged through the suction pump. Therefore, the dust generated during polishing is filtered and removed by the cloth sleeve in the filter cartridge, and the fine dust particles in the air are further removed by the electrostatic dust collection generated by the dust collection component, thereby ensuring the cleanliness of the working environment during granite grinding and polishing.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.
[0026] This application discloses an electrostatic collection device for polishing dust. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A polishing dust electrostatic collection device includes a clamping component 1, a dust collection hood 2, a filter cartridge 3, and a dust removal component 4. The clamping component 1 includes a clamping seat 11 and a sliding frame 15. The clamping seat 11 is fixedly assembled by locking bolts 12, and screw hole frames 13 are vertically fixed on the side end face of the clamping seat 11. The sliding frame 15 is horizontally fixed on the top surface of the screw hole frame 13 on one side of the clamping seat 11, and the dust collection hood 2 is slidably assembled on the sliding frame 15. The bottom surface of the dust collection hood 2 is open, and a suction tube 22 is fixedly connected to the top surface of the dust collection hood 2. The other end of the suction tube 22 is... The filter cartridge 3 is assembled in a connected manner, and a mesh cylinder 31 is vertically fixed inside the filter cartridge 3. A cloth sleeve 32 is fitted and fixed on the inner wall of the mesh cylinder 31. The dust removal component 4 includes a dust removal box 41. The top surface of the dust removal box 41 is connected and assembled with the bottom end of the filter cartridge 3. A suction pump 42 is connected and fixed on the bottom surface of the dust removal box 41. An opening is provided on one side of the dust removal box 41. A pull plate 43 is inserted into the opening of the dust removal box 41. A discharge electrode 44 is horizontally fixed on the vertical end face of the inner side of the pull plate 43. Multiple dust collection plates 45 are horizontally and vertically inserted into the discharge electrode 44. When polishing granite, the granite is placed on the top surface of the clamping seat 11 of the clamping component 1. During polishing, the dust collection hood 2 is pushed to slide on the sliding frame 15, so that the dust collection hood 2 is above the granite. During polishing, the suction pump 42 on the bottom surface of the dust collection box 41 is activated, which drives the dust generated during granite polishing into the dust collection hood 2. The dust-laden air is guided into the filter cartridge 3 through the suction pipe 22. After the dust-laden air passes through the cloth cover 32 to remove large particles of impurities, the air containing fine dust particles is guided into the dust collection component 4. When the air flows in the dust collection box 41, the air contacts the metal dust collection plate 45 and generates an electrostatic field through the high voltage power supply to collect the fine dust particles in the settled air. Then the air is discharged through the suction pump 42. Therefore, the dust generated during polishing is filtered and removed by the cloth cover 32 in the filter cartridge 3, and the fine dust particles in the air are further removed by the electrostatic dust collection generated by the dust collection component 4, thus ensuring the cleanliness of the working environment during granite polishing.

[0028] Reference Figure 3 and Figure 5 A sliding bracket 21 is vertically fixed to the rear vertical end face of the dust collection cover 2, and the bottom of the sliding bracket 21 is horizontally slidably assembled on the sliding frame 15. The sliding bracket 21 on the dust collection cover 2 slides horizontally on the sliding frame 15 and slides laterally to reach the top of the granite.
[0029] Reference Figure 3 The filter cartridge 3 has internal threads on both the upper and lower sides of its inner wall. The other end of the suction tube 22 and the top of the dust collection box 41 are both connected and fixed with screw caps 23. The screw caps 23 on the suction tube 22 and the dust collection box 41 are threaded onto the internal threads of the filter cartridge 3. When the dust collection hood 2, filter cartridge 3, and dust collection component 4 are assembled and connected, the assembly and connection of the dust collection hood 2, filter cartridge 3, and dust collection component 4 are completed by threading the screw caps 23 on the suction tube 22 and the dust collection box 41 onto the internal threads of the filter cartridge 3.
[0030] Reference Figure 3 A rotating frame 33 is vertically fixed in the screw cap 23 of the dust collector box 41, and a rotating motor 34 is vertically fixed on the bottom surface of the rotating frame 33. A scraper 35 is vertically rotatably connected to the top surface of the rotating frame 33, and the scraper 35 penetrates the bottom surface of the cloth cover 32 and inserts into the interior of the cloth cover 32. To ensure the filtration effectiveness of the cloth cover 32, the rotating motor 34 on the bottom surface of the rotating frame 33 is activated to drive the scraper 35 to rotate. The scraper 35 presses against the inner wall of the cloth cover 32 to scrape away dust and impurities, ensuring the filtration effectiveness of the cloth cover 32. Brushes 36 are evenly fixed on the vertical end face of the scraper 35. The brushes 36 fixed on the scraper 35 are used to brush away dust and impurities on the inner wall of the cloth cover 32, ensuring the filtration effectiveness of the cloth cover 32.
[0031] Reference Figure 4 A power supply 46 is fixed to the outer wall of the dust collection plate 45, and the output terminal of the power supply 46 is electrically connected to the discharge electrode 44 via a wire. The power supply 46 generates an electrostatic field to collect the settled dust. A controller 47 is connected in series with the output terminal of the power supply 46 via a wire. The controller 47 is used to adjust the output voltage and current of the high-voltage power supply to adapt to different dust concentrations.
[0032] The implementation principle of the electrostatic dust collection device for polishing in this application embodiment is as follows: During the polishing of granite, the granite is placed on the top surface of the clamping seat 11 of the clamping member 1. During polishing, the dust collection hood 2 is pushed to slide on the sliding frame 15. When the dust collection hood 2, filter cartridge 3, and dust removal component 4 are assembled and connected, they are threaded onto the internal thread of the filter cartridge 3 via the suction pipe 22 and the screw cap 23 on the dust removal box 41, thus completing the assembly and connection of the dust collection hood 2, filter cartridge 3, and dust removal component 4, placing the dust collection hood 2 above the granite. During polishing, the suction pump 42 on the bottom surface of the dust removal box 41 is activated, driving the dust generated during granite polishing into the dust collection hood 2. The dust-laden air is guided into the filter cartridge 3 through the suction pipe 22, and the dust-laden air passes through the cloth cover 32. After filtering out large particles of impurities, in order to ensure the effectiveness of the filter by the cloth sleeve 32, the rotating motor 34 on the bottom surface of the rotating frame 33 is started to drive the scraper 35 to rotate. The scraper 35 presses against the inner wall of the cloth sleeve 32 to scrape off the dust and impurities on the inner wall of the cloth sleeve 32, thus ensuring the effectiveness of the filter by the cloth sleeve 32. The air containing fine dust particles is guided into the dust collector 4. When the air flows in the dust collector box 41, the air contacts the metal dust collection plate 45 and generates an electrostatic field through the high voltage power supply to collect the fine dust particles in the settled air. Then the air is discharged through the suction pump 42. Therefore, the dust air generated by polishing is filtered out by the cloth sleeve 32 in the filter cartridge 3, and the fine dust particles in the air are further removed by the electrostatic dust collection generated by the dust collector 4.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
