Description

Technical Field

[0001] This invention relates to the field of dust explosion-proof motor technology, specifically to a dust removal mechanism and a dust explosion-proof motor. Background Technology

[0002] Explosion-proof dust motors are special motors designed to isolate combustible dust.

[0003] The dust explosion-proof motor mainly consists of an explosion-proof shell, a body, and a base. During use, the body is installed on the base with fastening bolts. The outer explosion-proof shell is a protective structure that isolates external dust during the operation of the motor. Dust adhering to the outside of the explosion-proof shell is usually cleaned manually by workers using cleaning tools.

An adapter rod 24 is fixedly connected to the outer sides of both ends of the filter cloth 21. One end of the adapter rod 24 is rotatably connected to... There is an isolation strip 25, and a first insert plate 26 is fixedly connected to the end of the isolation strip 25 away from the adapter rod 24. A first clamping plate 27 is sleeved on the outer side of the end of the first insert plate 26 away from the isolation strip 25, and the end of the first clamping plate 27 away from the first insert plate 26 is fixedly connected to the explosion-proof shell 12.

A fixing component 7 is provided on the upper end of the explosion-proof shell 12, and a blower component 8 is provided on one end of the rotating component 3.

[0022] Example 2: See Figure 1 - Figure 6 Unlike the first embodiment described above, the rotating assembly 3 includes a motor 31 fixedly connected to the outer side of one end of the explosion-proof housing 12. The output shaft of the motor 31 passes through the explosion-proof housing 12 and is fixedly connected to a turntable 32. A rocker arm 33 is rotatably connected to the middle of the turntable 32. A second clamping plate 34 is rotatably connected to the end of the rocker arm 33 away from the turntable 32. A second insert plate 35 is inserted inside the end of the second clamping plate 34 away from the rocker arm 33. The end of the second insert plate 35 away from the second clamping plate 34 is fixedly connected to the filter cloth 21. After the motor 31 is started, the output shaft drives the turntable 32 to rotate. After the turntable 32 rotates, it drives the rocker arm 33 to rotate, thereby allowing the rocker arm 33 to drive the filter cloth 21 to move through the second clamping plate 34 and the second insert plate 35.

[0023] Example 3, see Figure 1 - Figure 6Unlike the second embodiment described above, the elastic component 4 includes a third insert plate 41 fixedly connected to the end of the filter cloth 21 away from the motor 31, and a third clamping plate 42 is sleeved on the outer side of the end of the third insert plate 41 away from the filter cloth 21. A telescopic sleeve 43 is fixedly connected to the side of the third clamping plate 42 away from the third insert plate 41, and a spring 44 is sleeved on the outer side of the telescopic sleeve 43. The end of the spring 44 near the third clamping plate 42 is fixedly connected to the third clamping plate 42, and the end of the spring 44 away from the third clamping plate 42 is fixedly connected to the explosion-proof housing 12. After the filter cloth 21 moves, the third insert plate 41 and the third clamping plate 42 are pulled to move by the positioning rod 51, the rotating cylinder 52, the slider 22, the first slide rail 23, and the second guide rail 72. After the third insert plate 41 and the third clamping plate 42 move, the spring 44 is stretched or compressed under the restriction of the telescopic sleeve 43, thereby causing the slider 22 to move back and forth.

[0024] Example 4, see Figure 1 - Figure 6 Unlike the above embodiment 3, the auxiliary component 5 includes a positioning rod 51 that is attached to the inner side of the middle of the filter cloth 21, and a rotating cylinder 52 is fixedly connected inside the positioning rod 51. The lower end of the rotating cylinder 52 is rotatably connected to the explosion-proof shell 12. After the filter cloth 21 moves, the third insert plate 41 and the third clamping plate 42 are pulled to move by the positioning rod 51, the rotating cylinder 52, the slider 22, the first slide rail 23 and the second guide rail 72.

[0025] Example 5, see Figure 1 - Figure 6 Unlike the above embodiment four, the cleaning component 6 includes a sleeve plate 61 fixedly connected to the inner sides of both ends of the explosion-proof shell 12, and a fixing plate 62 fixedly connected to the upper end of the sleeve plate 61. A cleaning brush 63 is fixedly connected to the lower end of the fixing plate 62, and the side of the cleaning brush 63 away from the fixing plate 62 is attached to the filter cloth 21. The reciprocating movement of the slider 22, together with the fixing plate 62 and the cleaning brush 63, cleans both sides of the filter cloth 21.

[0026] Example 6, see Figure 1 - Figure 6 Unlike the fifth embodiment described above, the explosion-proof housing 12 has three sets of fixing plates 62 and cleaning brushes 63 inserted into the inner side of one end. The reciprocating movement of the slider 22, in conjunction with the fixing plates 62 and cleaning brushes 63, cleans both sides of the filter cloth 21.

[0027] Example 7, see Figure 1 - Figure 6Unlike Embodiment Six above, the fixing component 7 includes a cover plate 71 that is attached to the upper side of the explosion-proof housing 12, and a second guide rail 72 is fixedly connected to the lower side of the cover plate 71. The lower end of the second guide rail 72 is sleeved on the outside of the slider 22, and a connecting plate 73 is fixedly connected to both ends of the cover plate 71. A fixing block 74 is attached to the lower side of the connecting plate 73, and the fixing block 74 is fixedly connected to the explosion-proof housing 12 at the end near the explosion-proof housing 12. Bolts 75 are threadedly engaged between the connecting plate 73 and the fixing block 74. The cover plate 71 drives the second guide rail 72 to be inserted into the explosion-proof housing 12. When the second guide rail 72 is inserted, it is sleeved on the outside of the slider 22 on the upper side of the filter cloth 21. At the same time, the connecting plate 73 and the fixing block 74 are attached. Then, the bolts 75 are screwed through and screwed into the connecting plate 73 and the fixing block 74 for fixing.

[0028] Example 8, see Figure 1 - Figure 6 Unlike Embodiment 7 described above, the blower assembly 8 includes a protective shell 81 fixedly connected to the inner side of the explosion-proof housing 12 near the motor 31, and a first gear 82 fixedly connected to the end of the turntable 32 away from the motor 31. The end of the first gear 82 away from the turntable 32 passes through the explosion-proof housing 12 and the protective shell 81 and is inserted into the protective shell 81. The outer teeth of the middle end of the first gear 82 are engaged with a toothed belt 83, and the inner teeth of the toothed belt 83 away from the protective shell 81 are engaged with a second gear 84. One side of the second gear 84 is rotatably connected to the protective shell 81. A fan blade 85 is fixedly connected to the side of the second gear 84 near the filter cloth 21, and the end of the fan blade 85 away from the second gear 84 passes through the protective shell 81. After the first gear 82 rotates, it drives the second gear 84 to rotate through the toothed belt 83. After the second gear 84 rotates, it drives the fan blade 85 to rotate, thereby using the rotation of the fan blade 85 to make the air inside the explosion-proof housing 12 flow.

[0029] Example 9, see Figure 1 - Figure 6 Unlike Embodiment 8 above, the diameter of the first gear 82 is larger than the diameter of the second gear 84, and the rotation of the first gear 82 drives the second gear 84 to rotate through the toothed belt 83.

[0030] Working principle: In use, the filter cloth 21, supported by the adapter rod 24, is first inserted into the explosion-proof housing 12 along with the slider 22. During the insertion process, the first insert plate 26 is inserted into the first clamping plate 27, the second insert plate 35 is inserted into the second clamping plate 34, and the third insert plate 41 is inserted into the third clamping plate 42. Simultaneously, the middle end of the filter cloth 21 is wrapped around the outside of the two sets of rotating cylinders 52. Then, the cover plate 71 is inserted into the explosion-proof housing 12 along with the second guide rail 72. The second guide rail 72 is fitted over the filter cloth 21 during insertion. On the outer side of the upper slider 22, the connecting plate 73 and the fixing block 74 are attached. Then, the bolt 75 is screwed through and into the connecting plate 73 and the fixing block 74 for fixation. In subsequent use, while the explosion-proof shell 12 protects the inner explosion-proof shell 12, the filter cloth 21 at both ends of the explosion-proof shell 12 can also be used for heat exchange. When it is necessary to clean the filter cloth 21 at both ends of the explosion-proof shell 12, the motor 31 can be started. After the motor 31 is started, the output shaft drives the turntable 32 to rotate. After the turntable 32 rotates, it drives the swing arm 33 to rotate. This allows the swing arm 33 to move the filter cloth 21 via the second clamping plate 34 and the second insert plate 35. After the filter cloth 21 moves, it is pulled by the positioning rod 51, the rotating cylinder 52, the slider 22, the first slide rail 23, and the second guide rail 72, causing the third insert plate 41 and the third clamping plate 42 to move. After the third insert plate 41 and the third clamping plate 42 move, they are stretched or compressed by the telescopic sleeve 43, causing the slider 22 to move back and forth. The reciprocating movement of the slider 22, in conjunction with the fixing plate 62 and the cleaning brush 63, cleans both sides of the filter cloth 21. When the turntable 32 rotates, it drives the first gear 82 to rotate under the protection of the protective shell 81. After the first gear 82 rotates, it drives the second gear 84 to rotate through the toothed belt 83. After the second gear 84 rotates, it drives the fan blade 85 to rotate. Thus, the rotation of the fan blade 85 allows the air inside the explosion-proof shell 12 to flow. After the air inside the explosion-proof shell 12 flows, the outside air enters the explosion-proof shell 12 from the filter cloth 21 at the other end of the explosion-proof shell 12. Then, the airflow is discharged from the filter cloth 21 near the end of the fan blade 85, thereby improving the heat dissipation effect.
