Description

Technical Field

[0001] The invention belongs to the technical field of generators, and in particular relates to a carbon powder collecting device. Background Art

[0002] The excitation brush holder for a phase-converter generator is an essential component of power plant equipment. It generally consists of two main components: an excitation power unit and an excitation regulator. Generator excitation systems include DC exciters, brushless exciters, and AC exciters.

[0003] During the operation of a condenser's excitation brush holder, friction between the carbon brushes and the slip rings produces fine carbon dust, which scatters onto the insulating components between the slip rings and the brush holder and throughout the unit, causing insulation degradation. Current solutions primarily rely on manual, periodic cleaning, which is labor-intensive.

[0004] After searching, a Chinese patent with publication number CN 222422695 U3 discloses a carbon powder collection device, which is applied to the excitation brush holder of a phase regulator. The excitation brush holder of the phase regulator includes a housing, a fixing frame arranged in the housing, a carbon brush assembly and a slip ring; the carbon powder collection device includes a dust suction pipe, a connecting assembly and a fan assembly. The dust suction pipe is arranged on the fixing frame. The dust suction pipe has a dust suction nozzle, which is aligned with the contact position of the carbon brush assembly and the slip ring. One end of the connecting assembly is connected to the output end of the dust suction pipe, and the other end is connected to the fan assembly. The carbon powder collection device can automatically complete the cleaning and collection of carbon powder, saving labor costs. In the above patent, the back-flushing device adopts pulse control, which can regularly back-flush the filter cartridge, thereby cleaning the carbon powder attached to the filter cartridge and collecting the carbon powder into the collection box below, thereby ensuring the filter cartridge's filtering effect on the carbon powder. However, since the back-flushing pipe of the back-flushing device is fixedly installed, the range of the blown gas is limited, making it difficult to comprehensively clean the surface of the filter cartridge, resulting in poor cleaning and collection effects.

[0028] like Figures 1 to 7As shown, an embodiment of the present invention provides a carbon powder collection device, including a collection box 1, a partition 104 is fixedly connected to the inner side of the collection box 1, a top pressing component 2 is installed in the middle of the partition 104, a collection groove 106 is opened at the bottom of the collection box 1, a support frame 107 is fixedly connected to the inner side of the collection groove 106, a bottom supporting component 3 is installed on the top of the support frame 107, a collection box 108 is installed at the bottom of the collection groove 106, a filter cartridge 105 is installed between the top pressing component 2 and the bottom supporting component 3, a driving component 4 is installed between the partition 104 and the supporting frame 107, a cleaning component 5 is installed on the left side of the driving component 4, and an electromagnetic control component 6 is installed on the front and back of the cleaning component 5. The fixed frame 501 is provided with a movable frame 502 on the front and back sides of the inner side of the fixed frame 501, a cleaning brush 503 is fixedly connected to the inner side of the movable frame 502, fixed blocks 505 are fixedly connected on both sides of the movable frame 502, cylindrical rods 504 are fixedly connected on both sides of the inner wall of the fixed frame 501, and the cylindrical rods 504 are movably connected to the fixed blocks 505. The driving assembly 4 includes a driving motor 401 fixedly connected to the top of the partition 104, the output shaft of the driving motor 401 is fixedly connected to the screw rod 402, the outer side of the screw rod 402 is threadedly connected to the lifting plate 403, the left side of the lifting plate 403 is fixedly connected to the outer side of the fixed frame 501, and the bottom outside the screw rod 402 is fixedly connected to the driving gear 404.

[0029] In the embodiment of the present application, when the cleaning component 5 is in the non-cleaning state, the cleaning component 5 is located at the bottom of the outer side of the filter cartridge 105, and the electromagnetic coil 602 is in a non-energized state. The cleaning brush 503 is separated from the outer surface of the filter cartridge 105. When the filter cartridge 105 needs to be cleaned, the drive motor 401 is started to drive the screw rod 402 to reverse. Under the action of the threaded thrust of the screw rod 402, the lifting plate 403 drives the cleaning component 5 to move vertically upward to the top of the outer side of the filter cartridge 105, and then the drive motor 401 drives the screw rod 402 to rotate forward. At the same time, the electromagnetic coil 602 is energized, and the movable electromagnetic block 603 and the fixed electromagnetic block 604 are attracted, so that the movable electromagnetic block 603 pushes the movable frame 502 through the control rod 605. The cleaning brush 503 moves in the direction close to the surface of the filter cartridge 105 so that the cleaning brush 503 contacts the outer side of the filter cartridge 105. When the screw rod 402 rotates forward, the cleaning assembly 5 is driven to move vertically downward through the lifting plate 403. While the screw rod 402 rotates, the supporting frame 301 is driven to rotate through the meshing action of the driving gear 404 and the driven gear 302, thereby driving the filter cartridge 105 to rotate, so that the cleaning brush 503 moves downward to clean the outer surface of the filter cartridge 105 while the filter cartridge 105 keeps rotating, thereby being able to comprehensively clean the outer surface of the filter cartridge 105. The cleaned carbon powder falls into the inner side of the collection box 108 through the collection groove 106 under the action of gravity, thereby realizing the collection of carbon powder.

[0030] Among them, the bottom of the left side of the collection box 1 is fixedly connected with a collection pipe 101, the top of the right side of the collection box 1 is installed with a negative pressure fan 102, and the four sides of the bottom of the collection box 1 are fixedly connected with support legs 103.

[0031] The negative pressure fan 102 generates negative pressure inside the collection box 1 , and the carbon powder is sucked into the collection box 1 through the collection pipe 101 .

[0032] Among them, the top pressing assembly 2 includes a movable tube 201 movably sleeved in the middle of the partition 104, the top of the movable tube 201 is movably sleeved with a fixed rod 202, the bottom of the fixed rod 202 is fixedly connected to a pressing plate 204, the top of the fixed rod 202 is fixedly connected to a control panel 203, and the bottom of the pressing plate 204 is in close contact with the top of the filter cartridge 105.

[0033] A ventilation slot is provided in the middle of the partition 104 , and the movable tube 201 is movably sleeved inside the ventilation slot and has a rotation function.

[0034] The outer movable sleeve of the fixed rod 202 is provided with a pressure spring 205 , and the pressure spring 205 is located between the pressing plate 204 and the movable tube 201 .

[0035] The pressure spring 205 exerts a downward push on the pressing plate 204 , so that the pressing plate 204 exerts a downward squeezing force on the filter cartridge 105 , thereby enabling the filter cartridge 105 to be stably installed between the pressing plate 204 and the support frame 301 .

[0036] The bottom of the outer side of the movable tube 201 is fixedly connected to a rubber sheet 206 , and the edge of the bottom of the rubber sheet 206 is fixedly connected to the four sides of the pressing plate 204 .

[0037] The rubber sheet 206 can seal the gap between the movable tube 201 and the pressing plate 204 , thereby preventing air carrying carbon powder from being directly discharged from the gap between the movable tube 201 and the pressing plate 204 .

[0038] The bottom support assembly 3 includes a support frame 301 rotatably connected to the top of the support frame 107 , and a driven gear 302 is fixedly sleeved on the bottom outside the support frame 301 . The driven gear 302 is meshed with the driving gear 404 .

[0039] The bottoms of the support frame 301 and the filter cartridge 105 are adapted to each other. When the drive motor 401 drives the screw rod 402 to rotate, the support frame 301 can be driven to rotate through the engagement of the driving gear 404 and the driven gear 302, thereby driving the filter cartridge 105 to rotate, and no relative rotation will occur between the filter cartridge 105 and the support frame 301.

[0040] Among them, the driving component 4 also includes a positioning rod 405 movably sleeved on the top of the lifting plate 403, one end of the positioning rod 405 is fixedly connected to the bottom of the partition 104, and the other end of the positioning rod 405 is fixedly connected to the top of the support frame 107.

[0041] The lifting plate 403 plays a role in positioning the positioning rod 405, so that when the screw rod 402 rotates, it can drive the lifting plate 403 to move up and down without offset rotation.

[0042] Among them, the electromagnetic control component 6 includes an external shell 601 fixedly connected to the surface of the fixed frame 501, and the electromagnetic coil 602 is fixedly connected around the inner wall of the external shell 601. One end of the inner wall of the external shell 601 is fixedly connected to the fixed electromagnetic block 604, and the inner side of the fixed electromagnetic block 604 is movably sleeved with a control rod 605. One end of the control rod 605 is fixedly connected to the surface of the movable frame 502, and the other end of the control rod 605 is fixedly connected to the movable electromagnetic block 603.

[0043] When the cleaning assembly 5 moves to the top position of the outer side of the filter cartridge 105, the electromagnetic coil 602 is energized, so that the movable electromagnetic block 603 and the fixed electromagnetic block 604 generate magnetism, and the movable electromagnetic block 603 and the fixed electromagnetic block 604 are attracted together, so that the movable electromagnetic block 603 pushes the control rod 605 to extend outward, and then the cleaning brush 503 contacts the outer side of the filter cartridge 105.

[0044] Among them, the end of the movable electromagnetic block 603 away from the control rod 605 is fixedly connected to the movable rod 606, and the end of the movable rod 606 away from the movable electromagnetic block 603 is fixedly connected to the stop block 607. The outer movable sleeve of the movable rod 606 is provided with a return spring 608, and the return spring 608 is located between the stop block 607 and the outer side of the external shell 601.

[0045] When the electromagnetic coil 602 is not energized, under the elastic force of the return spring 608 , the movable rod 606 drives the movable electromagnetic block 603 to move away from the fixed electromagnetic block 604 , thereby separating the cleaning brush 503 from the outside of the filter cartridge 105 .

[0046] Working principle and usage process:

[0047] When the filter cartridge 105 is not in the cleaning state, the cleaning assembly 5 is located at the bottom of the outer side of the filter cartridge 105, and the electromagnetic coil 602 is in the non-energized state. The cleaning brush 503 is separated from the outer surface of the filter cartridge 105. When the filter cartridge 105 needs to be cleaned, the drive motor 401 is started to drive the screw rod 402 to reverse. Under the action of the threaded thrust of the screw rod 402, the lifting plate 403 drives the cleaning assembly 5 to move vertically upward to the top of the outer side of the filter cartridge 105, and then the drive motor 401 drives the screw rod 402 to rotate forward. At the same time, the electromagnetic coil 602 is energized, and the movable electromagnetic block 603 and the fixed electromagnetic block 604 are attracted, so that the movable electromagnetic block 603 pushes the movable frame 502 to move closer to the filter cartridge 105 through the control rod 605. The cylinder 105 moves in the direction of the surface, so that the cleaning brush 503 contacts the outer side of the filter cylinder 105. When the screw rod 402 rotates forward, the cleaning component 5 is driven to move vertically downward through the lifting plate 403, and while the screw rod 402 rotates, the supporting frame 301 is driven to rotate through the meshing action of the driving gear 404 and the driven gear 302, thereby driving the filter cylinder 105 to rotate, thereby realizing the downward movement of the cleaning brush 503 to clean the outer surface of the filter cylinder 105 while the filter cylinder 105 keeps rotating, so that the outer surface of the filter cylinder 105 can be fully cleaned, and the cleaned carbon powder falls into the inner side of the collection box 108 through the collection groove 106 under the action of gravity, thereby realizing the collection of carbon powder.
