[0030] Example 1

[0031] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a dust suppression device for feeding materials into a thermal power plant boiler. The device includes...

[0032] The mounting mechanism 100 includes a base 101, a housing 102 fixedly connected to the top of the base 101, and a protective door 103 rotatably connected to the outside of the housing 102. A protective net 104 is fixedly connected to the outside of the housing 102. An air intake component 105 is adapted to be installed on the outside of the housing 102. A power component 106 is provided inside the housing 102. An output component 107 is provided inside the housing 102. An auxiliary component 108 is provided inside the housing 102. A dust collection component 109 is adapted to be installed on the outside of the auxiliary component 108.

[0033] Specifically, the air intake component 105 includes an air pipe 105a fixedly connected to the outside of the housing 102, a connector 105b fixedly connected to one end of the air pipe 105a, and a reciprocating assembly 105c disposed on the outside of the air pipe 105a.

[0034] Furthermore, the power component 106 includes a motor 106a adapted to be installed on the inner wall of the housing 102, a water pipe 106b fixedly connected to the output end of the motor 106a, and a disc 106c fixedly connected to the outside of the water pipe 106b. A round rod 106d is fixedly connected to the outside of the disc 106c, and a crescent block 106e is fixedly connected to the outside of the disc 106c. An opening and closing component 106f is provided inside the water pipe 106b.

[0035] Furthermore, the output component 107 includes a first rotating rod 107a rotatably connected inside the housing 102, a first protrusion 107b fixedly connected to the outside of the first rotating rod 107a, and a drive assembly 107c disposed on the outside of the first rotating rod 107a.

[0036] Preferably, the drive assembly 107c includes a connecting plate 107c-1 fixedly connected to the outside of the first rotating rod 107a, a sliding groove 107c-2 opened on the outside of the connecting plate 107c-1, and an arc-shaped groove 107c-3 opened on the outside of the connecting plate 107c-1. A fixing block 107c-4 is fixedly connected to the outside of the connecting plate 107c-1, and a semi-circular block 107c-5 is fixedly connected to the outside of the fixing block 107c-4.

[0037] It should be noted that the auxiliary component 108 includes a second rotating rod 108a rotatably connected inside the housing 102, a second protrusion 108b fixedly connected to the outside of the second rotating rod 108a, and a stop block 108c fixedly connected to the outside of the second rotating rod 108a. A connecting component 108d is provided on the outside of the second rotating rod 108a.

[0038] Preferably, the connecting assembly 108d includes a turntable 108d-1 fixedly connected to the outside of the second rotating rod 108a, a turntable 108d-1 fixedly connected to the outside of the first rotating rod 107a, and a belt 108d-2 disposed on the outside of the two sets of turntables 108d-1.

[0039] The dust collection component 109 includes a sleeve 109a respectively sleeved on the outside of the first rotating rod 107a and the second rotating rod 108a, a groove 109b opened on the inside of the sleeve 109a, and a dust-absorbing cotton 109c disposed on the outside of a set of sleeves 109a.

[0040] When in use, connect the connector 105b to the vacuum head, connect one end of the water pipe 106b to the water source, install the two sets of sleeves 109a on the first rotating rod 107a and the second rotating rod 108a respectively, and make the vacuum cotton 109c located between the pressure block 105c-5 and the air pipe 105a.

[0041] While vacuuming, the motor 106a is started. The operation of the motor 106a drives the water pipe 106b to rotate. The water pipe 106b drives the disc 106c, the crescent block 106e, and the round rod 106d fixedly connected to the outside of the disc 106c to rotate. When the round rod 106d rotates, it will continuously rotate into the slide groove 107c-2. The push of the round rod 106d will drive the connecting plate 107c-1 to rotate. The connecting plate 107c-1 will drive the first rotating rod 107a to rotate. At the same time, the first rotating rod 107a will drive the second rotating rod 108a to rotate through the turntable 108d-1 and the belt 108d-2. This will drive the two sets of sleeves 109a to rotate and roll up the vacuuming cotton 109c.

[0042] The arc-shaped groove 107c-3 design ensures the stability of the connecting plate 107c-1 during rotation. Simultaneously, because each rotation of the round rod 106d corresponds to one small rotation of the connecting plate 107c-1 in conjunction with the sliding groove 107c-2, it ensures that during dust collection, the sucked-in dust enters the air pipe 105a and continuously adheres to the surface of the dust-collecting cotton 109c. The intermittent rotation of the connecting plate 107c-1 ensures that the dust-collecting cotton 109c is fully hydrated. This device effectively absorbs dust. While fully utilizing the dust-absorbing cotton 109c, it also allows for continuous replacement, ensuring its sustained and effective dust absorption. By continuously rewinding the dust-laden cotton 109c, the surface dust can be easily collected. Once dust collection is complete, simply remove the cotton 109c; this method is more convenient and faster than traditional transmission methods.

[0043] In summary, when the equipment is performing dust suppression work, the intermittently rolled-up dust-collecting cotton 109c can not only effectively collect dust and facilitate the overall use by the staff, but also ensure that the dust-collecting cotton 109c is fully utilized and its purpose is fully realized.

[0044] Example 2

[0045] Referring to 7, which is the second embodiment of the present invention, this embodiment differs from the first embodiment in that: the reciprocating assembly 105c includes a pressure rod 105c-1 slidably connected to the outside of the air tube 105a, a connecting plate 105c-2 fixedly connected to the outside of the pressure rod 105c-1, and a hinge rod 105c-3 hinged to one end of the pressure rod 105c-1. A fixing rod 105c-4 is hinged to the other end of the hinge rod 105c-3. A pressure block 105c-5 is fixedly connected to one end of the fixing rod 105c-4. A protrusion 105c-6 is fixedly connected to the outside of the air tube 105a. A first spring 105c-7 is provided at the top of the protrusion 105c-6. The fixing rod 105c-4 slides on the outside of the air tube 105a.

[0046] During use, when the connecting plate 107c-1 operates intermittently, it causes the fixing block 107c-4 and the semi-circular block 107c-5 on the outer side of the fixing block 107c-4 to rotate. As the semi-circular block 107c-5 rotates, it presses against the pressure rod 105c-1, and through the connecting plate 105c-2 on the outer side of the pressure rod 105c-1, it presses against the first spring 105c-7, causing the first spring 105c-7 to contract. Simultaneously, the sliding pressure rod 105c-1, in conjunction with the hinge rod 105c-3, moves the pressure block 105c-5 at one end of the fixing rod 105c-4 away from the dust-collecting cotton 109c, thereby... This ensures that when the vacuuming cotton 109c is being rolled up, the pressure block 105c-5 will not squeeze the vacuuming cotton 109c, thus ensuring the stability of the vacuuming cotton 109c during the rolling process. Because the pressure block 105c-5 is removed, the airflow during vacuuming causes the vacuuming cotton 109c to adhere tightly to the pressure block 105c-5. Therefore, when the vacuuming cotton 109c moves during rolling, it will not come into contact with the air pipe 105a, thus preventing the vacuuming cotton 109c from rubbing against the air pipe 105a during movement and causing dust to fall. This further improves the dust collection efficiency of the equipment.

[0047] In summary, while the dust-collecting cotton 109c is in operation, the pressure block 105c-5 will not compress the dust-collecting cotton 109c. This ensures that the dust-collecting cotton 109c can be stably wound up, and also prevents the dust-collecting cotton 109c from rubbing against the air tube 105a during the winding process, which would cause dust to fall. This further improves the dust collection effect of the equipment.

[0048] Example 3

[0049] Reference Figure 8 This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the opening and closing component 106f includes a second spring 106f-1 fixedly connected inside the water pipe 106b, a long rod 106f-2 fixedly connected to one end of the second spring 106f-1, and a plug 106f-3 fixedly connected to the outside of the long rod 106f-2. A short rod 106f-4 is slidably connected inside the crescent block 106e. An arc-shaped block 106f-5 is fixedly connected to one end of the short rod 106f-4. A connecting rod 106f-6 is hinged to the other end of the short rod 106f-4. The other end of the connecting rod 106f-6 is hinged to one end of the long rod 106f-2.

[0050] When in use, as the connecting plate 107c-1 rotates, it causes the end of the sliding groove 107c-2 of the connecting plate 107c-1 to rotate to the inner arc of the crescent block 106e, and squeezes the arc block 106f-5 on the inner side of the crescent block 106e. With the design of the short rod 106f-4 and the connecting rod 106f-6, the long rod 106f-2 will squeeze the second spring 106f-1, and cause the plug 106f-3 on the outside of the long rod 106f-2 to be misaligned with the nozzle on the outside of the water pipe 106b, thereby causing the water inside the water pipe 106b to spray out through the nozzle.

[0051] The sprayed water can pre-wet the dust-collecting cotton 109c, thereby further improving the dust collection effect of the dust-collecting cotton 109c and ensuring that the equipment can collect dust efficiently and stably.

[0052] In summary, when the equipment is performing dust suppression, the intermittently wound dust-collecting cotton 109c, combined with the pre-wetting design of the dust-collecting cotton 109c, can not only effectively collect dust, but also ensure the stability of the dust-collecting cotton 109c during winding, avoiding the dust falling off due to friction between the dust-collecting cotton 109c and the air pipe 105a during the winding process. This further improves the dust collection effect of the equipment.
