Description

Technical Field

[0001] This invention relates to the field of dust removal technology, and more specifically to a dust removal device for low-voltage electrical equipment. Background Technology

[0002] Dust removal is necessary in workplaces where precision and high-value low-voltage electrical equipment is located, in order to protect the equipment. Traditional dust removal devices allow air to enter freely and filter the dust in the air to achieve the purpose of dust removal. However, the fluidity of air means that the amount of air entering the dust removal device is very limited, resulting in poor dust removal effect.

[0003] To address the problems existing in traditional dust removal devices, Chinese Patent No. CN221799864U discloses a ventilation and dust removal device, including a liquid storage tank. A first connecting pipe is fixedly connected to one side of the liquid storage tank, and one end of the first connecting pipe is connected to the interior of the liquid storage tank. A sleeve is fitted onto the first connecting pipe, and a second connecting pipe is fixedly connected to the sleeve. An air inlet is fixedly connected to the end of the second connecting pipe, and a first filter screen is fixedly connected to the air inlet. A lifting assembly is fixedly connected to one side of the liquid storage tank, and the output end of the lifting assembly is connected to the sleeve. The system includes a fixed pipe connection, a support shell on one side of the liquid storage tank, a fan fixedly connected to the support shell, a third connecting pipe fixedly connected between the input end of the fan and the liquid storage tank, a support ring fixedly connected inside the liquid storage tank, an installation frame on the upper end of the support ring, a second filter screen fixedly connected inside the installation frame, and a stirring assembly inside the liquid storage tank. In this dust removal device, the fan can introduce air into the liquid storage tank for filtration, and the fan can also guide airflow, promoting dust removal from more air.

[0004] The above-mentioned dust removal device has the following problems during actual use: as the usage time increases, more and more dust will accumulate on the first and second filter screens, causing blockage; in addition, since the first and second filter screens are both fixed inside the liquid storage tank, they are inconvenient to disassemble or replace, so the first and second filter screens cannot be cleaned, the blockage problem cannot be solved, and thus the filtration effect is affected. Summary of the Invention

[0005] The present invention aims to provide a dust removal device for low-voltage electrical equipment to solve the problem of easy clogging of the filter screen in existing dust removal devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dust removal device for low-voltage electrical equipment, comprising a housing and a filter plate, wherein the top of the housing is provided with an exhaust hole, the filter plate is provided with a plurality of filter holes along the length direction of the filter plate, and the inner walls on both sides of the housing are provided with vertical sliding grooves, the filter plate being slidably connected to the sliding grooves; rotating shafts are rotatably connected to both sides of the filter plate inside the housing, and a plurality of flexible cleaning layers are provided on the rotating shafts along the axial direction of the rotating shafts, the flexible cleaning layers being located on the movement trajectory of the filter plate; further comprising a power mechanism for driving the filter plate to reciprocate vertically, a drive mechanism for simultaneously driving the two rotating shafts to rotate, and an introduction mechanism for introducing air into the housing.

[0007] The principles and advantages of this scheme are:

[0008] 1. The outside air is introduced into the chamber through the inlet mechanism. After the dust in the air is filtered by the filter plate, it is discharged from the exhaust port. Compared with the existing technology, this solution can drive the filter plate to move vertically back and forth along the path of the slide groove through the power mechanism, thereby realizing the vibration of the filter plate, which can promote the separation of dust from the filter plate and avoid the clogging of the filter hole.

[0009] 2. During the vertical reciprocating motion of the filter plate in this solution, the top of the filter plate intermittently approaches the upper flexible cleaning layer, and the bottom of the filter plate intermittently approaches the lower flexible cleaning layer, so that the flexible cleaning layer can intermittently clean the filter holes and avoid clogging of the filter holes.

[0010] 3. This solution uses a drive mechanism to simultaneously rotate two shafts, which in turn rotate the flexible cleaning layer, thereby enhancing the cleaning effect on the filter holes and preventing them from becoming clogged.

[0011] Furthermore, the power mechanism includes a side box fixedly connected to the housing, a round shaft rotatably connected to the inside of the side box, a power unit for driving the round shaft to rotate, a slide groove communicating with the inside of the side box, a cylindrical cam coaxially connected to the round shaft, a curved groove provided on the cylindrical cam, a power block slidably connected in the curved groove, and the power block fixedly connected to the filter plate.

[0012] With the above setup, the power unit drives the circular shaft to rotate, the circular shaft drives the cylindrical cam to rotate, and the cylindrical cam drives the filter plate to move vertically back and forth along the path of the slide groove through the curved groove and the power block, thereby realizing the vibration of the filter plate.

[0013] Furthermore, the drive mechanism includes a worm gear coaxially connected to the rotating shaft and a worm located on both sides of the cylindrical cam coaxially connected to the round shaft. The rotating shaft extends into the interior of the side box, and the worm meshes with the worm gear.

[0014] With the above setup, during the rotation of the circular shaft, the circular shaft drives the upper and lower worm gears to rotate synchronously. The worm gears mesh with the worm wheel to drive the rotating shaft to rotate, that is, the rotating shafts on the upper and lower sides of the filter plate rotate synchronously.

[0015] Furthermore, the side wall of the filter plate is provided with a side groove, which communicates with the filter holes; the box body is provided with an extension plate, which extends into the side groove and can move vertically relative to each other within the side groove; the top and bottom of the extension plate are provided with several anti-clogging rods for passing through the filter holes.

[0016] With the above settings, during the vertical reciprocating motion of the filter plate, the extension plate moves relatively vertically within the side groove. The anti-clogging rod at the top of the extension plate continuously moves in and out of the filter hole, and the anti-clogging rod at the bottom of the extension plate also continuously moves in and out of the filter hole, thereby preventing the filter hole from becoming clogged.

[0017] Furthermore, the width of the anti-blocking rod gradually decreases from the end near the extension plate to the free end.

[0018] With the above settings, the change in the width of the anti-clogging rod enhances the cleaning effect on the filter holes and prevents clogging.

[0019] Furthermore, the rotating shaft is provided with several cleaning layers along the axial direction of the rotating shaft, and the cleaning layers are located between two adjacent flexible cleaning layers; the cleaning layer includes a cleaning block and several cleaning rods fixedly connected to the cleaning block. The cleaning block is provided with a circular hole, through which the rotating shaft passes, and the diameter of the rotating shaft is smaller than the diameter of the circular hole; the bottom of the cleaning rod is provided with several first bristles, and the free ends of the first bristles are in contact with the filter plate; it also includes a linkage mechanism that drives multiple cleaning blocks to reciprocate along the axial direction of the rotating shaft at the same time as the two worm gears rotate.

[0020] With the above configuration, during the rotation of the circular shaft, the linkage mechanism drives multiple cleaning blocks to reciprocate along the axial direction of the shaft. The cleaning blocks drive the first brush bristles to reciprocate laterally via the cleaning rod. The first brush bristles can clean the position between adjacent filter holes on the filter plate, avoiding dust accumulation and thus preventing dust from clogging the filter holes.

[0021] Furthermore, the linkage mechanism includes linkage blocks located on both sides of the filter plate, linkage arms fixedly connected to the cleaning block, and a disc coaxially connected to the worm gear. The distance between the two linkage blocks is greater than the distance between the two rotating shafts. The linkage blocks are laterally slidably connected to the housing, and the linkage arms are fixedly connected to the linkage blocks. A swing arm is rotatably connected to the eccentric part of the disc, and the end of the swing arm away from the disc is rotatably connected to the linkage block.

[0022] With the above setup, during the rotation of the worm gear, the worm gear also drives the disc to rotate, and the disc drives the linkage block to reciprocate laterally through the swing arm, and the linkage block drives the cleaning block to reciprocate laterally through the linkage arm.

[0023] Furthermore, the flexible cleaning layer includes a plurality of second bristles circumferentially fixed to the rotating shaft, the second bristles being inclined and located on the movement trajectory of the filter holes; the cleaning rod is inclined, and the second bristles are located on the movement trajectory of the cleaning rod.

[0024] With the above settings, during the rotation of the shaft, the shaft drives multiple sets of second brushes to rotate, allowing more second brushes to enter and exit the filter holes, increasing the frequency of the second brushes entering and exiting the filter holes, enhancing the cleaning effect of the filter holes, and preventing clogging.

[0025] During the horizontal reciprocating motion of the cleaning rod, it can extend between adjacent second brush bristles to clean them, preventing dust from adhering to the second brush bristles and ensuring the cleaning effect of the second brush bristles on the filter holes. In addition, the rotating shaft can drive multiple sets of second brush bristles to rotate at the same time, so that multiple second brush bristles in each set can pass over the cleaning rod one by one, thereby enhancing the cleaning effect of each set of second brush bristles.

[0026] Furthermore, the top of the box is connected to several spray pipes, and spray nozzles are connected to the spray pipes.

[0027] With the above setup, clean water is introduced into the spray pipe, and the clean water is sprayed through the nozzles onto the inside of the chamber, which can reduce dust; in addition, it can also clean the first brush bristles, the second brush bristles, the filter plate and the filter holes, and prevent the filter holes from becoming clogged.

[0034] Example

[0035] The basics are as follows: Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 As shown: A dust removal device for low-voltage electrical equipment includes a housing 10 and a filter plate 11. An exhaust port 12 is provided on the top of the housing 10. A plurality of filter holes 111 are provided along the length of the filter plate 11, and the filter plate 11 is located inside the housing 10. It also includes an air intake mechanism for introducing air into the housing 10. The air intake mechanism is an air intake pump 13. The input end of the air intake pump 13 is connected to the outside, and the output end of the air intake pump 13 is connected to the inside of the housing 10, with the output end of the air intake pump 13 located near the bottom of the housing 10.

[0036] Vertical grooves are formed on the inner walls of both sides of the housing 10, and the filter plate 11 is slidably connected to the grooves. Rotating shafts 20 are rotatably connected to the upper and lower sides of the filter plate 11 inside the housing 10. Several flexible cleaning layers are provided on the rotating shafts 20 along the axial direction of the rotating shafts 20. The flexible cleaning layers are located on the movement trajectory of the filter plate 11. The flexible cleaning layers include several second bristles 21 circumferentially fixed to the rotating shafts 20. The second bristles 21 are inclined from left to right and are located on the movement trajectory of the filter holes 111, that is, the second bristles 21 can extend into the filter holes 111 for cleaning.

[0037] It also includes a power mechanism for driving the filter plate 11 to reciprocate vertically. The power mechanism includes a side box 30 fixedly connected to the housing 10, a round shaft 31 rotatably connected to the inside of the side box 30, and a power unit for driving the round shaft 31 to rotate. The slide groove on the right side of the housing 10 communicates with the inside of the side box 30. The round shaft 31 is vertically arranged, and a cylindrical cam 32 is coaxially connected to the round shaft 31. A curved groove is opened on the cylindrical cam 32, and a power block 33 is slidably connected in the curved groove. The power block 33 is fixedly connected to the filter plate 11.

[0038] It also includes a drive mechanism for simultaneously driving two rotating shafts 20 to rotate. The drive mechanism includes a worm wheel 40 coaxially connected to the rotating shaft 20 and a worm 41 coaxially connected to the cylindrical cam 32 on the upper and lower sides. The rotating shaft 20 extends into the interior of the side box 30, and the worm wheel 40 is located inside the side box 30. There are two worms 41, which are located at the upper and lower ends of the cylindrical shaft 31 respectively, and the worms 41 mesh with the worm wheel 40.

[0039] A side groove 42 is formed on the side wall of the filter plate 11. The side groove 42 is located on the rear side of the filter plate 11 and communicates with the filter hole 111. An extension plate 43 is fixedly connected to the rear inner wall of the housing 10. The extension plate 43 extends into the side groove 42. During the vertical reciprocating motion of the filter plate 11, the extension plate 43 can move relatively vertically within the side groove 42. Several anti-clogging rods 44 for passing through the filter hole 111 are fixedly connected to the top and bottom of the extension plate 43. The width of the anti-clogging rods 44 gradually decreases from the end near the extension plate 43 to the free end.

[0040] A plurality of cleaning layers are provided on the rotating shaft 20 along the axial direction of the rotating shaft 20, and the cleaning layers are located between two adjacent flexible cleaning layers. The cleaning layer includes a cleaning block 50 and a plurality of cleaning rods 51 fixedly connected to the cleaning block 50. The cleaning block 50 has a circular hole, through which the rotating shaft 20 passes. The diameter of the rotating shaft 20 is smaller than the diameter of the circular hole, that is, the cleaning block 50 can move along the axial direction of the rotating shaft 20 without affecting the rotation of the rotating shaft 20. A plurality of first bristles 52 are fixedly connected to the bottom of the cleaning rods 51. The free ends of the first bristles 52 are in contact with the filter plate 11, and the free ends of the first bristles 52 are located between two adjacent filter holes 111. The cleaning rods 51 are inclined from right to left, that is, the inclination direction of the cleaning rods 51 is opposite to that of the second bristles 21. The second bristles 21 are located on the movement trajectory of the cleaning rods 51, so that the cleaning rods 51 can act on the second bristles 21.

[0041] It also includes a linkage mechanism that drives multiple cleaning blocks 50 to reciprocate along the axial direction of the rotating shaft 20 as the two worm gears 41 rotate. The linkage mechanism includes linkage blocks 60 located on the upper and lower sides of the filter plate 11, linkage arms 61 fixedly connected to the cleaning blocks 50, and a disc 62 coaxially connected to the worm gears 41. The distance between the two linkage blocks 60 is greater than the distance between the two rotating shafts 20. The linkage blocks 60 are laterally slidably connected to the housing 10. The linkage blocks 60 can extend into the side housing 30 and reciprocate laterally within the side housing 30. The linkage arms 61 are fixedly connected to the linkage blocks 60. A swing arm 63 is rotatably connected to the disc 62 at an eccentric position. The end of the swing arm 63 away from the disc 62 is rotatably connected to the linkage blocks 60. The two linkage blocks 60 move in the same direction.

[0042] The specific implementation process is as follows:

[0043] Install the housing 10 in the desired position, start the air pump 13 to introduce outside air into the housing 10, filter the dust in the air through the filter plate 11 and discharge it from the exhaust port 12, and collect the dust at the bottom of the housing 10.

[0044] Over time, dust will accumulate near the filter holes 111. To prevent dust from clogging the filter holes 111, the following methods can be used:

[0045] When the motor is started, the output shaft of the motor drives the drive gear to rotate. The drive gear meshes with the driven gear to drive the round shaft 31 to rotate. The round shaft 31 drives the cylindrical cam 32 to rotate. The cylindrical cam 32 drives the filter plate 11 to move vertically back and forth along the path of the slide groove through the curved groove and the power block 33, thereby realizing the vibration of the filter plate 11, which can promote the separation of dust from the filter plate 11 and prevent the filter holes 111 from being blocked.

[0046] During the vertical reciprocating motion of the filter plate 11, the extension plate 43 moves relatively vertically within the side groove 42. The anti-clogging rod 44 at the top of the extension plate 43 continuously moves in and out of the filter hole 111, and the anti-clogging rod 44 at the bottom of the extension plate 43 also continuously moves in and out of the filter hole 111, thereby preventing the filter hole 111 from becoming clogged. Furthermore, due to the change in the width of the anti-clogging rod 44, the cleaning effect on the filter hole 111 is enhanced, preventing clogging.

[0047] During the vertical reciprocating motion of the filter plate 11, the top of the filter plate 11 intermittently approaches the upper second brush bristles 21, and the bottom of the filter plate 11 intermittently approaches the lower second brush bristles 21, so that the second brush bristles 21 can intermittently extend into the filter holes 111 for cleaning and to prevent the filter holes 111 from becoming clogged.

[0048] During the rotation of the circular shaft 31, the circular shaft 31 drives the upper and lower worm gears 41 to rotate synchronously. The worm gears 41 mesh with the worm wheel 40 to drive the rotating shaft 20 to rotate, that is, the rotating shafts 20 on the upper and lower sides of the filter plate 11 rotate synchronously. During the rotation of the rotating shaft 20, the rotating shaft 20 drives multiple sets of second bristles 21 to rotate, so that more second bristles 21 enter and exit the filter hole 111, and also increases the frequency of the second bristles 21 entering and exiting the filter hole 111, thereby enhancing the cleaning effect on the filter hole 111 and preventing clogging.

[0049] During the rotation of the worm gear 41, the worm gear 41 also drives the disk 62 to rotate. The disk 62 drives the linkage block 60 to move laterally and reciprocally via the swing arm 63. The linkage block 60 drives the cleaning block 50 to move laterally and reciprocally via the linkage arm 61. The cleaning block 50 drives the first brush bristles 52 to move laterally and reciprocally via the cleaning rod 51. The first brush bristles 52 can clean the position on the filter plate 11 between adjacent filter holes 111, avoiding dust accumulation and thus preventing dust from clogging the filter holes 111. Furthermore, because the second brush bristles 21 are tilted to the right... The cleaning rod 51 is tilted to the left, so during its lateral reciprocating motion, it can reach between adjacent second bristles 21 to clean them, preventing dust from adhering to the second bristles 21 and ensuring the cleaning effect of the second bristles 21 on the filter holes 111. In addition, the rotating shaft 20 can drive multiple sets of second bristles 21 to rotate simultaneously, so that the multiple bristles 21 in each set can pass over the cleaning rod 51 one by one, thereby enhancing the cleaning effect of each set of second bristles 21.

[0050] In this embodiment, the top of the housing 10 is connected to several spray pipes, and the spray pipes are connected to nozzles 70, which are located inside the housing 10. Clean water is introduced into the spray pipes, and the clean water is sprayed through the nozzles 70 to act on the inside of the housing 10, which can reduce dust. In addition, it can also clean the first bristles 52, the second bristles 21, the filter plate 11 and the filter holes 111, so as to prevent the filter holes 111 from becoming clogged.

[0051] In this embodiment, the bottom of the box 10 has a discharge port, and a bottom block 80 is threaded onto the discharge port; the mixture of dust and water will be collected at the bottom of the box 10. When it is necessary to clean the inside of the box 10, the bottom block 80 can be removed from the discharge port to complete the cleaning work.
