Description

Technical Field

[0001] This invention relates to the field of dust removal technology in construction, and in particular to a dust collection system for material silos based on the walking paths of construction workers. Background Technology

[0002] In many manufacturing enterprises, raw materials, intermediates, products, or by-products, as well as other powdery solids, are stored in silos. When materials are unloaded and loaded onto trucks, the lack of effective dust collection devices means that a large amount of dust cannot be collected and treated in a timely manner, resulting in a poor working environment and affecting the health of workers. The dust collection system for hardened material yard transport roads involves regularly sweeping and watering the material yard roads to reduce dust and dry them, and increasing the frequency of watering according to the weather conditions. At the same time, transport vehicles are covered with geotextile fabric to prevent spillage during transportation.

[0003] However, the aforementioned dust collection methods still generate dust. After the dust settles by spraying water, it is distributed along the walking paths of construction workers, causing the soles of their shoes to stick and indirectly polluting the production workshop environment. Furthermore, if the settled dust is not cleaned up in time, it will dry after a certain period of time, and when vehicles pass by again, it will cause dust to be stirred up again, affecting the health of the workers. Cleaning with sweeping vehicles not only causes congestion for transport vehicles but also wastes resources and cannot simultaneously handle the dust generated in the workshop, making it time-consuming and labor-intensive. Therefore, the present invention solves the shortcomings of the above-mentioned technical problems. Summary of the Invention

[0004] Based on the aforementioned technical problems, this invention proposes a dust collection system for material silos based on the walking path of construction workers.

[0005] This invention proposes a dust collection system for material silos based on the walking path of construction workers. The system includes a workshop for raw material production. A rectangular array of suction pipes connected to the interior of the workshop is arranged on one side of the workshop. One end of each suction pipe is fixedly connected to a connecting pipe. A first suction fan is mounted on one side surface of the workshop via a connecting block. The air inlet of the first suction fan is fixedly connected to the interior of the connecting pipe via the connecting pipe. A sealing cover is provided outside the workshop. A dust suppression mechanism is provided on the upper surface of the sealing cover, a dust collection mechanism is provided on the lower surface of the sealing cover, and a dust removal mechanism is provided inside the sealing cover.

[0006] The dust-reducing mechanism sprays water mist as it rotates circumferentially, causing the dust to settle.

[0007] The dust collection mechanism cleans and collects the dust settled by the dust settling mechanism.

[0008] The dust removal mechanism filters and collects the dust drawn from the factory and the dust collected by the dust collection mechanism.

[0009] Preferably, the dust suppression mechanism includes a T-shaped water pipe for connection, with water distribution pipes fixedly sleeved on the inner walls of both ends of the T-shaped water pipe, infrared sensors fixedly connected to one side surface of each of the two water distribution pipes, atomizing nozzles fixedly connected to the lower surface of the water distribution pipes in a rectangular array, and a rotating bearing installed on the lower surface of the T-shaped water pipes via a connecting rod, with a support column fixedly sleeved on the outer surface of the rotating bearing.

[0010] Through the above technical solution, the lower surface of the T-shaped water pipe rotates on the surface of the support column via a connecting rod and a rotating bearing. In order to settle the dust raised around the sealing cover, water is supplied to the water distribution pipes at both ends of the T-shaped water pipe and sprayed out through atomizing nozzles to settle the dust. Furthermore, the water pressure causes the T-shaped water pipe to drive the water distribution pipes to rotate circumferentially at a uniform speed, thereby increasing the range of dust settling. In order to prevent pedestrians from being wetted by the atomizing nozzles, an infrared sensor is used to detect pedestrians on the lower surface of the atomizing nozzles. When a pedestrian passes by, the infrared sensor can control the atomizing nozzles to stop operating.

[0011] Preferably, the dust suppression mechanism further includes a water inlet pipe for water supply. The lower outer surface of the water inlet pipe and the middle outer surface are both fixedly fitted with limit sealing rings. A rotating cylinder is rotatably fitted onto the outer surface of the water inlet pipe. The upper and lower surfaces of the rotating cylinder are in sliding contact with one side surface of the two limit sealing rings, respectively. The outer surface of the rotating cylinder is fixedly fitted onto the upper inner wall of the T-shaped water pipe.

[0012] Through the above technical solution, in order to use water pressure to make the water distribution pipe rotate at a uniform speed in a circumferential direction, the T-shaped water pipe is connected to the water inlet pipe through the rotating drum. The rotating drum rotates on the outer surface of the water inlet pipe under the action of two limiting sealing rings, thereby enabling the water supply pressure entering the water inlet pipe to cause the water distribution pipe to rotate and achieve a wide range of water mist spraying.

[0013] Preferably, the dust collection mechanism includes a rotating ring rotatably connected to the lower surface of the sealing cover via a bearing. Brush bristles are fixedly connected to the lower surface of the rotating ring in a circular array. Inner ring teeth are fixedly connected to the inner surface of the rotating ring in a circular array. A collection bucket is disposed in the middle of the sealing cover. A magnetic induction liquid level sensor is fixedly installed on the upper surface of the collection bucket. A reduction motor is fixedly connected to one outer surface of the collection bucket via a connecting block. A drive gear is fixedly connected to the outer surface of the output shaft of the reduction motor via a coupling. The outer surface of the drive gear meshes with the surface of the inner ring teeth. A brake wheel is fixedly connected to the lower surface of the collection bucket in a circular array.

[0014] Through the above technical solution, the water mist sprayed by the atomizing nozzle causes dust to settle on the path walked by construction workers around the sealed cover. To avoid dust accumulation or continued dust generation after drying, a rotating ring rotates on the lower surface of the sealed cover, causing the cone-shaped bristles to rotate, thereby sweeping the dust settled on the road surface. In order to drive the rotating ring to rotate the bristles, the reduction motor installed on the outer surface of the collection bucket can be controlled to drive the drive gear to rotate, thus causing the inner ring gear to mesh with it to drive the rotating ring to rotate, realizing the sweeping of the bristles. At the same time, in order to facilitate the movement of the collection bucket to adapt to various places, a brake wheel is set on the lower surface of the collection bucket for movement. In order to detect the volume of dust particles collected in the collection bucket, a magnetic induction liquid level sensor can be used to monitor the volume inside the bucket.

[0015] Preferably, the dust collection mechanism further includes a second suction fan fixedly connected to the inner wall of the sealing cover via a connecting block, the air inlet end of the second suction fan being fixedly connected to a dust collection pipe, and the lower surface of the dust collection pipe being fixedly connected to a conical dust collection hood.

[0016] In order to collect the swept dust, the second suction fan inside the sealed cover operates to draw and collect the swept dust through the conical dust collection hood and dust collection pipe.

[0017] Preferably, the dust removal mechanism includes a conical tube fixedly connected to the inside of the collection bucket. The upper surface of the conical tube is fixedly connected from top to bottom to a first vortex shell and a second vortex shell. The air outlet of the first suction fan is fixedly connected to the air inlet of the first vortex shell through a connecting pipe, and the air outlet of the second suction fan is fixedly connected to the air inlet of the second vortex shell through a connecting pipe.

[0018] Through the above technical solution, in order to filter and remove the dust extracted from the factory and the dust drawn by the second suction fan, the dust enters the conical tube from the first vortex shell and the dust from the second vortex shell for collection. When the dust and dust enter the conical tube, due to the shape of the first and second vortex shells, the dust and dust enter the conical tube at a tangential cyclone angle and form a rotating airflow. The dust particles in the dust and dust will generate inertia with the rotation of the airflow, and thus accumulate on the inner wall of the conical tube. Then the dust particles will be sent into the collection bucket below by the airflow, while the airflow will enter the upper part of the first vortex shell through the area with lower air pressure in the middle of the cyclone.

[0019] Preferably, the dust removal mechanism further includes a dust removal pipe that is fixedly connected to the inside of the first vortex shell, the upper surface of the sealing cover is fixedly sleeved with the outer surface of the dust removal pipe, the upper surface of the dust removal pipe is fixedly connected with the lower surface of the support column, and the lower inner wall and the upper inner wall of the dust removal pipe are both fixedly connected with mounting plates with through holes.

[0020] In order to remove the rotating airflow generated in the conical tube, the above technical solution connects the upper surface of the first vortex shell to a concave dust removal tube, so that the upward airflow enters the dust removal tube through the through hole of the mounting plate for further filtration.

[0021] Preferably, the dust removal mechanism further includes a heating wire cage frame fixedly inserted into the inner wall of the through hole of the mounting plate, the outer surface of the heating wire cage frame is covered with filter adsorption cotton, and a baffle plate whose upper surface contacts the lower surface of the mounting plate is fixedly connected to the inner side wall of the lower end of the dust removal tube, and a material drop hole is opened through the upper surface of the baffle plate.

[0022] Through the above technical solution, in order to filter the dust contained in the upward rotating airflow, the airflow is filtered and adsorbed by the annular array of filter adsorption cotton when passing through the dust removal pipe. At the same time, in order to improve the utilization rate of the filter adsorption cotton, the heating wire cage is used to dry the filter adsorption cotton, which facilitates the desorption of impurities on the filter adsorption cotton, and allows the dust particles to be discharged through the discharge holes on the baffle plate.

[0023] Preferably, the dust removal mechanism further includes a feed pipe fixedly connected to the inner wall of the lower end of the dust removal pipe by a fixing ring. A receiving hopper is provided between the fixing ring of the feed pipe and the baffle plate. The upper surface of the receiving hopper slides in contact with the lower surface of the baffle plate. A rotating motor is fixedly connected to the middle surface of the baffle plate. The outer surface of the output shaft of the rotating motor is fixedly connected to the upper surface of the receiving hopper through a coupling. An L-shaped suction pipe is installed through the surface of the feed pipe and extends into its interior. The lower surface of the receiving hopper is rotatably connected to the upper surface of the suction pipe through a rotating connecting flange.

[0024] Through the above technical solution, the rising rotating airflow passes through the feed pipe and the baffle plate into the dust removal pipe, where it is filtered and adsorbed by the filter adsorption cotton inside. In order to desorb the dry dust particles on the filter adsorption cotton, the motor is rotated to control the receiving hopper to rotate one by one on the upper surface of the suction pipe, so that the upper surface of the receiving hopper corresponds one by one with the discharge hole, and the suction pipe performs a suction action, thereby desorbing the dust particles on the filter adsorption cotton on the upper surface of the discharge hole one by one, so that the dust particles fall into the receiving hopper through the discharge hole and are discharged from the suction pipe.

[0025] Preferably, the dust removal mechanism further includes a third suction fan installed on the inner wall of the sealing cover via a connecting block. One end of the suction pipe is fixedly connected to the air inlet of the third suction fan, and the air outlet of the third suction fan is fixedly connected to a circulation pipe. One end of the circulation pipe is fixedly connected to the interior of the second vortex shell. The upper outer surface of the dust removal pipe is fixedly connected to an exhaust pipe arranged in a ring array, and one end of the exhaust pipe extends into the interior of the sealing cover.

[0026] Through the above technical solution, in order to generate a suction action in the suction pipe, a third suction fan is set at one end to adsorb dust particles on the filter adsorption screen. The suction dust particles are then re-filtered through the circulation pipe into the conical pipe. The filtered gas is then discharged from the top of the filter adsorption cotton to the discharge pipe, and then discharged into the sealed cover so that the second suction fan can perform suction to complete the circulation filtration.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. By setting up a dust suppression mechanism, dust generated along the walking path of construction workers can be suppressed. During the adjustment process, water is supplied to the distribution pipes at both ends of the T-shaped water pipe, and the water is sprayed out through atomizing nozzles to achieve dust settling. The water pressure causes the T-shaped water pipe to rotate the distribution pipes at a uniform speed, thereby increasing the dust settling range. In order to prevent pedestrians from getting wet from the atomizing nozzles, infrared sensors are used to detect pedestrians on the lower surface of the atomizing nozzles. When a pedestrian passes by, the infrared sensor can control the atomizing nozzles to stop operating. Thus, during the production process in the silo, the uniformly rotating atomizing nozzles can continuously suppress dust in the surrounding environment, avoiding the health impact of dust on construction workers.

[0029] 2. By setting up a dust collection mechanism, the dust settling from the dust suppression mechanism can be swept and collected in a timely manner. During the adjustment process, the rotating ring rotates on the lower surface of the sealing cover, causing the cone-shaped bristles to rotate, thereby sweeping the dust settling on the road surface. The second suction fan inside the sealing cover operates to draw and collect the swept dust through the cone-shaped dust collection hood and dust collection pipe, thus avoiding the need for manual labor to clean the settling dust irregularly and preventing the re-spreading of dust that could affect the health of construction workers.

[0030] 3. By setting up a dust removal mechanism, the dust drawn from the factory and the dust collected by the dust collection mechanism can be filtered and collected. During the adjustment process, the dust and powder enter the conical tube at a tangential cyclone angle and form a rotating airflow. The dust and powder particles will generate inertia with the rotation of the airflow, and thus accumulate on the inner wall of the conical tube. Then the dust particles will be sent into the collection bucket below by the airflow. The airflow will enter the upper part of the first vortex shell through the area with lower air pressure in the middle of the cyclone, and be filtered and adsorbed by the filter adsorption cotton of the ring array when passing through the dust removal pipe. The filtered gas is discharged from the upper end of the filter adsorption cotton to the discharge pipe, and then discharged into the sealed cover for the second suction fan to draw in and complete the cycle filtration, thereby avoiding the occurrence of dust. At the same time, the dust collected in the collection bucket can be reused, thus avoiding resource waste. Attached Figure Description

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0048] Reference Figures 1-15 A dust collection system for a material silo based on the walking path of construction workers includes a workshop 1 for raw material production. Suction pipes 2 are arranged in a rectangular array on one side of the workshop 1 and communicate with its interior. One end of the suction pipes 2 is fixedly connected to a connecting pipe 3. A first suction fan 4 is installed on one side surface of the workshop 1 through a connecting block. The air inlet of the first suction fan 4 is fixedly connected to the interior of the connecting pipe 3 through a connecting pipe. A sealing cover 5 is provided outside the workshop 1. A dust suppression mechanism 6 is provided on the upper surface of the sealing cover 5. A dust collection mechanism 7 is provided on the lower surface of the sealing cover 5. A dust removal mechanism 8 is provided inside the sealing cover 5.

[0049] like Figures 2-5 As shown, the dust settling mechanism 6 sprays water mist as it rotates circumferentially, thus settling the dust that has been raised.

[0050] To settle the dust raised around the sealing cover 5, the dust settling mechanism 6 includes a T-shaped water pipe 61 for connection. Water distribution pipes 62 are fixedly sleeved on the inner walls of both ends of the T-shaped water pipe 61. Atomizing nozzles 64 are fixedly connected to the lower surface of the water distribution pipes 62 in a rectangular array. A rotating bearing 65 is mounted on the lower surface of the T-shaped water pipe 61 via a connecting rod. A support column 66 is fixedly sleeved on the outer surface of the rotating bearing 65. The lower surface of the T-shaped water pipe 61 rotates on the surface of the support column 66 via the connecting rod and the rotating bearing 65, distributing water through the T-shaped water pipe 61 to its two ends. Water is supplied inside the water distribution pipe 62 and sprayed out through the atomizing nozzle 64 to achieve dust settling. The water pressure causes the T-shaped water pipe 61 to drive the water distribution pipe 62 to rotate circumferentially at a uniform speed, thereby increasing the dust settling range. In order to prevent pedestrians from being wetted by the atomizing nozzle 64, infrared sensors 63 are fixedly connected to one side of the surface of both water distribution pipes 62. The infrared sensors 63 detect pedestrians on the lower surface of the atomizing nozzle 64. When a pedestrian passes by, the infrared sensors 63 can control the atomizing nozzle 64 to stop operating.

[0051] In order to utilize water pressure to make the water distribution pipe 62 rotate at a uniform speed, the dust suppression mechanism 6 also includes a water inlet pipe 67 for water supply. The lower outer surface and the middle outer surface of the water inlet pipe 67 are fixedly fitted with limit sealing rings 68. A rotating cylinder 69 is rotatably fitted on the outer surface of the water inlet pipe 67. The upper and lower surfaces of the rotating cylinder 69 slide in contact with one side surface of the two limit sealing rings 68 respectively. The outer surface of the rotating cylinder 69 is fixedly fitted with the upper inner wall of the T-shaped water pipe 61, so that the T-shaped water pipe 61 is connected to the water inlet pipe 67 through the rotating cylinder 69. Under the action of the two limit sealing rings 68, the rotating cylinder 69 rotates on the outer surface of the water inlet pipe 67, thereby causing the water supply pressure entering the water inlet pipe 67 to cause the water distribution pipe 62 to rotate and achieve a wide range of water mist spraying.

[0052] By setting up a dust suppression mechanism 6, dust generated along the walking path of construction workers can be suppressed. During the adjustment process, water is supplied to the water distribution pipes 62 at both ends of the T-shaped water pipe 61, and the water is sprayed out through the atomizing nozzles 64 to achieve dust settling. The water pressure causes the T-shaped water pipe 61 to drive the water distribution pipes 62 to rotate at a uniform speed, thereby increasing the dust settling range. In order to prevent pedestrians from getting wet from the atomizing nozzles 64, the infrared sensor 63 detects pedestrians on the lower surface of the atomizing nozzles 64. When a pedestrian passes by, the infrared sensor 63 can control the atomizing nozzles 64 to stop operating. Thus, during the production process of the silo, the uniformly rotating atomizing nozzles 64 can continuously suppress dust in the surrounding environment, which can prevent dust from affecting the health of construction workers.

[0053] like Figures 6-8 As shown, the dust collection mechanism 7 performs a sweeping and collecting action on the dust settled by the dust settling mechanism 6.

[0054] The water mist sprayed from the atomizing nozzle 64 causes dust to settle on the path walked by construction workers around the sealing cover 5. To prevent dust accumulation or continued dust generation after drying, the dust collection mechanism 7 includes a rotating ring 71 rotatably connected to the lower surface of the sealing cover 5 via bearings. Brush bristles 72 are fixedly connected in a ring array on the lower surface of the rotating ring 71, and inner ring teeth 73 are fixedly connected in a ring array on the inner surface of the rotating ring 71. A collection bucket 74 is located in the middle of the sealing cover 5. The rotation of the rotating ring 71 on the lower surface of the sealing cover 5 causes the conical brush bristles 72 to rotate, thereby cleaning the dust settled on the road surface. To detect the volume of dust particles collected in the collection bucket 74, the collection bucket 74... A magnetic induction liquid level sensor 75 is fixedly installed on the upper surface. In order to drive the rotating ring 71 to rotate the brush bristles 72, a geared motor 76 is fixedly connected to one side of the outer surface of the collection bucket 74 through a connecting block. The outer surface of the output shaft of the geared motor 76 is fixedly connected to a drive gear 77 through a coupling. The outer surface of the drive gear 77 meshes with the surface of the inner ring tooth 73, thereby controlling the geared motor 76 installed on the outer surface of the collection bucket 74 to drive the drive gear 77 to rotate. Thus, the inner ring tooth 73 meshing with it can drive the rotating ring 71 to rotate, thereby cleaning the brush bristles 72. In order to facilitate the movement of the collection bucket 74 to adapt to various places, brake wheels 78 are fixedly connected in a ring array on the lower surface of the collection bucket 74.

[0055] In order to collect the swept dust, the dust collection mechanism 7 also includes a second suction fan 79 fixedly connected to the inner wall of the sealing cover 5 by a connecting block. The air inlet end of the second suction fan 79 is fixedly connected to a dust collection pipe 791, and the lower surface of the dust collection pipe 791 is fixedly connected to a conical dust collection hood 792. The second suction fan 79 inside the sealing cover 5 operates to draw and collect the swept dust through the conical dust collection hood 792 and the dust collection pipe 791.

[0056] By setting up a dust collection mechanism 7, the dust settled by the dust settling mechanism 6 can be swept and collected in a timely manner. During the adjustment process, the rotating ring 71 rotates on the lower surface of the sealing cover 5, causing the cone-shaped bristles 72 to rotate, thereby sweeping the dust settled on the road surface. The second suction fan 79 inside the sealing cover 5 operates, drawing and collecting the swept dust through the cone-shaped dust collection cover 792 and the dust collection pipe 791. This avoids the need for manual labor to clean the settled dust irregularly and also prevents dust from being stirred up again, thus avoiding the impact on the health of construction workers.

[0057] like Figure 7 and Figures 9-15 As shown, the dust removal mechanism 8 filters and collects the dust drawn from the factory 1 and the dust collected by the dust collection mechanism 7.

[0058] To filter and remove dust extracted from the factory 1 and dust drawn by the second suction fan 79, the dust removal mechanism 8 includes a conical tube 81 fixedly connected to the inside of the collection tank 74. A first vortex shell 82 and a second vortex shell 83 are fixedly connected from top to bottom on the upper surface of the conical tube 81. The outlet of the first suction fan 4 is fixedly connected to the inlet of the first vortex shell 82 via a connecting pipe, and the outlet of the second suction fan 79 is fixedly connected to the inlet of the second vortex shell 83 via a connecting pipe. Dust is filtered from the first vortex shell 82 and dust... Dust enters the conical tube 81 from the second vortex shell 83 for collection. When dust and particulate matter enter the conical tube 81, due to the shape of the first vortex shell 82 and the second vortex shell 83, the dust and particulate matter enter the conical tube 81 at a tangential cyclone angle and form a rotating airflow. The dust particles in the dust and particulate matter will generate inertia with the rotation of the airflow, and thus accumulate on the inner wall of the conical tube 81. Then the dust particles will be sent into the collection bucket 74 below by the airflow, while the airflow will enter the area above the first vortex shell 82 through the area with lower air pressure in the middle of the cyclone.

[0059] In order to remove the rotating airflow generated in the conical tube 81, the dust removal mechanism 8 also includes a dust removal pipe 84 that is fixedly connected to the inside of the first vortex shell 82. The upper surface of the sealing cover 5 is fixedly sleeved with the outer surface of the dust removal pipe 84, and the upper surface of the dust removal pipe 84 is fixedly connected to the lower surface of the support column 66. The inner sidewall of the lower end and the inner sidewall of the upper end of the dust removal pipe 84 are both fixedly connected with mounting plates 85 with through holes. The dust removal pipe 84, which is concave in shape, is connected to the upper surface of the first vortex shell 82, so that the upward airflow enters the dust removal pipe 84 through the through hole of the mounting plate 85 and is then filtered.

[0060] In order to filter the dust contained in the upward rotating airflow and to improve the utilization rate of the filter adsorption cotton 87, the dust removal mechanism 8 also includes a heating wire cage frame 86 fixedly inserted into the inner wall of the through hole of the mounting plate 85. The outer surface of the heating wire cage frame 86 is covered with filter adsorption cotton 87. The lower inner wall of the dust removal pipe 84 is fixedly connected to a baffle plate 88 whose upper surface contacts the lower surface of the mounting plate 85. The upper surface of the baffle plate 88 is provided with a discharge hole 89, so that the airflow is filtered and adsorbed by the annular array of filter adsorption cotton 87 when it passes through the dust removal pipe 84, and the heating wire cage frame 86 dries the filter adsorption cotton 87, which facilitates the desorption of impurities on the filter adsorption cotton 87, and allows dust particles to be discharged through the discharge hole 89 on the baffle plate 88.

[0061] The rising, rotating airflow passes through the feed pipe 90 and the baffle plate 88 into the dust removal pipe 84, where it is filtered and adsorbed by the filter adsorption cotton 87 inside. To desorb the dry dust particles on the filter adsorption cotton 87, the dust removal mechanism 8 also includes a feed pipe 90 fixedly connected to the inner wall of the lower end of the dust removal pipe 84 by a fixing ring. A receiving hopper 91 is provided between the fixing ring of the feed pipe 90 and the baffle plate 88. The upper surface of the receiving hopper 91 slides in contact with the lower surface of the baffle plate 88. A rotating motor 92 is fixedly connected to the middle surface of the baffle plate 88. The outer surface of the output shaft of the rotating motor 92 is connected to the receiving hopper 92 via a coupling. The upper surface of the hopper 91 is fixedly connected to the feed pipe 90, which extends through the surface and into the interior of the hopper. An L-shaped suction pipe 93 is installed therein. The lower surface of the receiving hopper 91 is rotatably connected to the upper surface of the suction pipe 93 via a rotating flange. The receiving hopper 91 is rotated one by one on the upper surface of the suction pipe 93 by the rotating motor 92, so that the upper surface of the receiving hopper 91 corresponds one by one with the discharge hole 89. This causes the suction pipe 93 to perform a suction action, thereby desorbing the dust particles on the filter adsorption cotton 87 on the upper surface of the discharge hole 89 one by one. The dust particles fall into the receiving hopper 91 through the discharge hole 89 and are discharged from the suction pipe 93.

[0062] To enable the suction pipe 93 to perform a suction action, the dust removal mechanism 8 also includes a third suction fan 94 installed on the inner wall of the sealing cover 5 via a connecting block. One end of the suction pipe 93 is fixedly connected to the air inlet of the third suction fan 94, and the air outlet of the third suction fan 94 is fixedly connected to a circulation pipe 95. One end of the circulation pipe 95 is fixedly connected to the interior of the second vortex shell 83. The upper outer surface of the dust removal pipe 84 is fixedly connected to an exhaust pipe 96 in a ring array. One end of the exhaust pipe 96 extends into the interior of the sealing cover 5. Through the operation of the third suction fan 94, it adsorbs dust particles on the filter adsorption net. The suctioned dust particles enter the conical pipe 81 through the circulation pipe 95 for further filtration. The filtered gas is discharged from the upper end of the filter adsorption cotton 87 to the exhaust pipe 96, and then discharged into the sealing cover 5 so that the second suction fan 79 can perform suction to complete the circulation filtration.

[0063] By setting up a dust removal mechanism 8, the dust drawn from the factory 1 and the dust collected by the dust collection mechanism 7 can be filtered and collected. During the adjustment process, the dust and powder enter the conical tube 81 at a tangential cyclone angle and form a rotating airflow. The dust and powder particles will generate inertia with the rotation of the airflow and thus accumulate on the inner wall of the conical tube 81. Then the dust particles will be sent into the collection bucket 74 below by the airflow. The airflow will enter the area above the first vortex shell 82 through the area with lower air pressure in the middle of the cyclone and be filtered and adsorbed by the filter adsorption cotton 87 of the annular array when passing through the dust removal pipe 84. The filtered gas is discharged from the upper end of the filter adsorption cotton 87 to the discharge pipe 96, and then discharged into the sealing cover 5 so that the second suction fan 79 can draw it to complete the cycle filtration, thereby avoiding the occurrence of dust. At the same time, the dust collected in the collection bucket 74 can be reused, thus avoiding the waste of resources.

[0064] Working principle: In a specific embodiment of the present invention, the dust generated by the production raw materials in the production room can be sucked out by the first suction fan 4, so that the dust is discharged through the suction pipe 2 and enters the conical pipe 81 from the first vortex shell 82 for collection through the connecting pipe 3.

[0065] At this time, water is supplied to the inlet pipe 67, and the water flow from the inlet pipe 67 enters the T-shaped water pipe 61. Water is then supplied to the water distribution pipes 62 at both ends of the T-shaped water pipe 61, so that the atomizing nozzle 64 atomizes and sprays out to achieve the settling of dust. Furthermore, the water pressure causes the T-shaped water pipe 61 to drive the water distribution pipe 62 to rotate circumferentially at a uniform speed, thereby increasing the range of dust settling. When a pedestrian passes under the atomizing nozzle 64, the infrared sensor 63 can detect the pedestrian and control the atomizing nozzle 64 to stop operating to avoid getting the pedestrian wet.

[0066] After the water mist generated by the atomizing nozzle 64 causes the dust to settle, the reduction motor 76 installed on the outer surface of the collection bucket 74 drives the drive gear 77 to rotate, which in turn causes the inner ring gear 73 to mesh with it to drive the rotating ring 71 to rotate, causing the bristles 72 distributed in a cone shape to rotate, thereby sweeping the dust settled on the road surface.

[0067] During the cleaning process of the brush 72, the second suction fan 79 inside the sealing cover 5 operates, allowing it to draw and collect the swept dust through the conical dust collection cover 792 and dust collection pipe 791. The collected dust enters the conical pipe 81 from the second vortex shell 83. When the dust enters the conical pipe 81, due to the shape of the first vortex shell 82 and the second vortex shell 83, the dust enters the conical pipe 81 at a tangential cyclone angle, forming a rotating airflow. The dust particles in the dust will generate inertia as the airflow rotates, thus accumulating on the inner wall of the conical pipe 81. Then, the dust particles will be sent into the collection bucket 74 below by the airflow, while the airflow will enter the area above the first vortex shell 82 through the area with lower air pressure in the middle of the cyclone.

[0068] The upward airflow enters the dust removal pipe 84 through the through hole of the mounting plate 85 and is filtered and adsorbed by the filter adsorption cotton 87 of the ring array. The filtered gas is discharged from the upper end of the filter adsorption cotton 87 to the discharge pipe 96, and then discharged into the sealing cover 5 so that the second suction fan 79 can perform suction to complete the cycle filtration.

[0069] The dust adsorbed on the filter cotton 87 is periodically desorbed to improve the utilization rate of the filter cotton 87. The filter cotton 87 is dried by the heating wire cage 86, which facilitates the desorption of impurities on the filter cotton 87. The receiving hopper 91 is rotated one by one on the upper surface of the suction pipe 93 by the rotating motor 92, so that the upper surface of the receiving hopper 91 corresponds one by one with the discharge hole 89. Then, the third suction fan 94 operates to make the suction pipe 93 perform a suction action, thereby desorbing the dust particles on the filter cotton 87 on the upper surface of the discharge hole 89 one by one. The dust particles fall into the receiving hopper 91 through the discharge hole 89. The dust particles in the receiving hopper 91 enter the conical pipe 81 through the circulation pipe 95 for re-filtration, thereby keeping the environment clean along the construction personnel's walking path.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
