Description

Technical Field

[0001] The present invention relates to the technical field of tunnel engineering, and in particular to an intelligent ventilation design method and system for high-altitude and cold environments. Background Art

[0002] The structure of a tunnel consists of two parts: the main building and ancillary equipment. The main building consists of the tunnel body and the tunnel portal. The ancillary equipment includes a car shelter, fire-fighting facilities, emergency communications and drainage facilities. When building a tunnel, ventilation equipment is a particularly critical facility. It can effectively replace the harmful gases and dust generated during tunnel mining to ensure the air quality inside the tunnel.

[0003] Existing ventilation equipment usually uses a ventilator connected to an air duct to discharge harmful gases and dust out of the tunnel, and then purifies them through purification equipment before discharge. This treatment method has a single purification effect and requires the use of dedicated harmful gas and dust treatment equipment for treatment respectively. The ventilation cost is high and the treatment efficiency is low. Harmful gases and dust cannot be graded and filtered. After the treatment, excessive harmful gases and dust may still exist in the exhaust gas. Therefore, this application provides an intelligent ventilation design method and system for high-altitude and cold environments to meet the needs. Summary of the Invention

The right end of the air suction hood is connected to a rotating shaft, and two groups of connecting holes are symmetrically arranged on both sides of the rotating shaft.

[0008] Optionally, each group of connecting holes is provided with four equally spaced holes on the side wall of the rotating shaft, and four connecting rods are provided at equal angles on the outside of each connecting hole. One end of the rotating shaft is connected to a pulley group, and the end of a pulley in the pulley group is connected to a drive motor, and the drive motor is installed on the top of the mounting frame.

[0009] Optionally, one end of the rotating shaft is connected to an air outlet hood, a storage box is sleeved on the outer side of the rotating shaft, stirring rods are distributed at equal angles on the inner side of the storage box, spherical activated carbon is arranged on the inner side of the storage box, and spiral grooves are arranged on the inner sides of the air suction hood and the air outlet hood.

[0010] Optionally, the spray assembly includes a water tank, which is installed on the top of the mounting frame. One end of the water tank is connected to a spray ring 1 through a pipeline, and the spray ring 1 is installed between the right end of the suction hood and the rotating shaft.

[0011] Optionally, one end of the water tank is connected to spray ring 2 through a pipeline, and spray ring 2 is installed at the end of the air outlet hood. Atomizing nozzle 1 is installed at an equal angle distribution on the inner side of spray ring 1, and atomizing nozzle 2 is installed at an equal angle distribution on the inner side of spray ring 2.

[0012] Optionally, the adsorption component includes an electrostatic generator, which is evenly distributed on the inner side of the side wall of the rotating shaft. There are four groups of electrostatic generators, and each group of electrostatic generators is symmetrically arranged on both sides of the rotating shaft. There are two electrostatic generators in each group, and each of the two ends of the electrostatic generator is symmetrically connected to two powered ends.

[0013] Optionally, an installation box is connected between the two powered ends, the powered ends are nested in the side walls of the installation box, springs are respectively sleeved on the outsides of the two powered ends, the springs are connected to the ends of the corresponding powered ends, the tail ends of the springs are connected to the inner wall of the installation box, and a counterweight is nested on the inside of the installation box.

[0014] Optionally, the counterweight block slides on the inner side of the mounting box, a contact block is nested on one side of the mounting box, the contact block is in contact with the contact plate, the connecting ends of the two symmetrical contact plates are respectively connected to the ends of two connecting rods in the four connecting rods, the outer sides of the four groups of connecting rods are provided with a synchronous wheel group, the end of one synchronous wheel in the synchronous wheel group is connected to a bevel gear, the bevel gear and the bevel gear are engaged with each other, and the bevel gear is installed at the end of a pulley in the pulley group.

[0015] This application also provides another technical solution: a method for using an intelligent ventilation system for a high-altitude cold environment, the method comprising the following steps:

[0016] S1. The operator transports the intelligent ventilation equipment to the designated location using a carrier, connects the ventilation pipe to the end of the auxiliary fan, and starts the ventilator and auxiliary fan during tunnel construction. Gas and dust are drawn in from the end of the ventilator and into the dustproof box. Large dust particles in the gas are isolated by the dustproof net.

[0017] S2. Driven by a driving motor, the stirring rod inside the storage box stirs and mixes the spherical activated carbon during rotation. The spherical activated carbon enters the inner channel of the rotating shaft through the connecting hole on the side wall of the rotating shaft and is located between the four connecting rods. The spherical activated carbon is evenly spaced in the vertical direction. When the exhaust gas passes through the inner channel of the rotating shaft, the spherical activated carbon located between the four connecting rods absorbs harmful substances in the exhaust gas. The spherical activated carbon located between the four connecting rods can be exchanged with the spherical activated carbon inside the storage box that is constantly stirred by the stirring rod due to the rotation of the storage box.

[0018] S3. As the air suction hood and the air outlet hood rotate along the rotating shaft, part of the water in the water tank enters the interior of the spray ring 1 and the spray ring 2 through the pipe. The atomizing nozzle 1 and the atomizing nozzle 2 are activated by the control module. The atomizing nozzle 1 installed at an equal angle is sprayed at the right end of the air suction hood, and the atomizing nozzle 2 installed at an equal angle is sprayed at the right end of the air outlet hood. The exhaust gas rotates through the spiral groove inside the air outlet hood and diverges to the right, reducing the pollution of the exhaust gas to the environment after discharge;

[0019] S4. When the exhaust gas passes through the internal channel of the rotating shaft, the two connecting rods with ions absorb dust particles in the exhaust gas through the principle of electrostatic adsorption, thereby reducing the dust content in the exhaust gas. At the same time, when the pulley group rotates, it drives the bevel gear to rotate, and the bevel gear and the bevel gear engage with each other. The bevel gear drives the synchronous wheel group connected at the end to rotate, and the synchronous wheel group drives the connecting rod to follow the rotation, so that the connecting rod can increase the adsorption surface through self-rotation while adsorbing dust.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above scheme, by setting up an adsorption component and a filtering component, the rotation of the rotating shaft drives the relatively symmetrical installation box to flip over, and the counterweight block is triggered by its own gravity to change whether it is connected to the energized end, so that the relatively connected connecting rods transmit charged ions through contact, and adsorb dust particles in the exhaust gas. At the same time, each connecting rod is driven and rotated by a synchronous wheel set, so that the outer surface of the connecting rod can adsorb dust, thereby improving the adsorption force of a single connecting rod on dust and enhancing the filtering effect of dust in the exhaust gas. When the counterweight block is no longer connected to the energized end, the two connecting rods connected to the corresponding contact plate no longer have dust adsorption capacity, which facilitates the spherical activated carbon to adsorb dust particles while rolling vertically inside the four connecting rods.

[0022] By setting up a spray component, before the exhaust gas absorbs dust particles and filters harmful gases, a pair of atomizing nozzles are used to atomize and spray the exhaust gas, and a second pair of atomizing nozzles are used to atomize and spray the exhaust gas, so that the atomized water increases the humidity in the exhaust gas, reduces the concentration of dust and impurities in the gas, prevents dust from being generated during gas treatment, and prevents pollution to the environment after the exhaust gas is discharged.

[0023] By setting up an air suction hood, an air outlet hood and an auxiliary fan, after the exhaust gas enters the air suction hood, the gas is gathered toward the inner channel of the rotating shaft through the spiral groove on the inner side of the air suction hood, thereby improving the treatment effect of the exhaust gas. The exhaust gas is discharged from the air outlet hood toward the auxiliary fan, and diffuses to the outside through the spiral groove on the inner side of the air outlet hood. With the auxiliary exhaust of the auxiliary fan, the flow speed of the exhaust gas is increased to prevent the gas from accumulating inside the device.

[0024] By setting up a dustproof box and a dustproof net, after the exhaust gas enters the dustproof box, large dust particles in the gas are isolated by the dustproof net, so that the dust size in the exhaust gas can be graded and processed, avoiding the adsorption component from being unable to adsorb large dust particles.

[0043] like Figure 1 and Figure 10As shown, an embodiment of the present invention provides an intelligent ventilation system for a high-altitude and cold environment, including a ventilator 1, a dust box 2 is provided on one side of the ventilator 1, a dust net 3 is provided on the inner side of the dust box 2, a mounting bracket 4 is provided on one side of the dust box 2, an auxiliary fan 5 is provided on one side of the mounting bracket 4, and a filter assembly 6 is provided. The filter assembly 6 is installed on one side of the dust box 2, and the filter assembly 6 is used to filter harmful substances in the exhaust gas, a spray assembly 7, the spray assembly 7 is installed on the top of the mounting bracket 4, and the spray assembly 7 is used to spray water to the exhaust gas, and an adsorption assembly 8. The adsorption assembly 8 is equidistantly installed on the inner side of the filter assembly 6, and the adsorption assembly 8 is used to adsorb dust and impurities.

[0044] like Figures 1 to 4 As shown, the filter assembly 6 includes an air suction hood 61, which is mounted on one side of the dustproof box 2, one end of the air suction hood 61 is connected to the dustproof box 2, and the right end of the air suction hood 61 is connected to a rotating shaft 62. Two groups of communicating holes 620 are symmetrically provided on both sides of the rotating shaft 62, and each group of communicating holes 620 is symmetrically provided with four communicating holes 620 on the side wall of the rotating shaft 62. Four connecting rods 621 are distributed at equal angles on the outside of each communicating hole 620. One end of the rotating shaft 62 is connected to a pulley group 63, and the end of one pulley in the pulley group 63 is connected to a driving motor 64. The driving motor 64 is mounted on the top of the mounting frame 4, and one end of the rotating shaft 62 is connected to an air outlet hood 65. A storage box 66 is sleeved on the outside of the rotating shaft 62, and stirring rods 67 are distributed at equal angles on the inside of the storage box 66. Spherical activated carbon 68 is provided on the inside of the storage box 66, and spiral grooves 69 are provided on the inside of the air suction hood 61 and the air outlet hood 65.

[0045] By setting up the filter component 6, the operator transports the intelligent ventilation equipment to the designated location through the carrying equipment, connects the ventilation pipe to the end of the auxiliary fan 5, and starts the ventilator 1 and the auxiliary fan 5 during tunnel construction. The gas and dust are sucked in from the end of the ventilator 1, and the gas enters the dust box 2. The large particles of dust in the gas are isolated by the dust net 3, and the driving motor 64 is started. The driving motor 64 drives the rotating shaft 62 to rotate through the pulley group 63, and the air suction hood 61 and the air outlet hood 65 rotate with the driving rotating shaft 62. After the airflow enters the air suction hood 61, the spiral groove 69 on the inside of the air suction hood 61 rotates, so that the exhaust gas gradually converges to the right end of the air suction hood 61, passes through the inner channel of the rotating shaft 62, and the storage box 66 rotates through the rotating shaft 62. The stirring rod inside the storage box 66 67 stirs and mixes the spherical activated carbon 68 during rotation, and the spherical activated carbon 68 enters the inner channel of the rotating shaft 62 through the connecting hole 620 on the side wall of the rotating shaft 62, and is located between the four connecting rods 621. The spherical activated carbon 68 is arranged equidistantly in the vertical direction. When the exhaust gas passes through the inner channel of the rotating shaft 62, the spherical activated carbon 68 located between the four connecting rods 621 adsorbs harmful substances in the exhaust gas. The spherical activated carbon 68 located between the four connecting rods 621 is exchanged with the spherical activated carbon 68 inside the storage box 66 that is always stirred by the stirring rod 67 during the rotation of the storage box 66, thereby improving the adsorption completeness of each spherical activated carbon 68, and avoiding the problem that a single spherical activated carbon 68 is always used to adsorb harmful substances, cannot be replaced and recycled, and has a short service life.

[0046] like Figures 3 to 6 As shown, the spray assembly 7 includes a water tank 71, which is mounted on the top of the mounting frame 4. One end of the water tank 71 is connected to a spray ring 1 72 through a pipeline. The spray ring 1 72 is mounted between the right end of the air suction hood 61 and the rotating shaft 62. One end of the water tank 71 is connected to a spray ring 2 73 through a pipeline. The spray ring 2 73 is mounted at the end of the air outlet hood 65. Atomizing nozzles 1 74 are installed on the inner side of the spray ring 1 72 at equal angles, and atomizing nozzles 2 75 are installed on the inner side of the spray ring 2 73 at equal angles.

[0047] By setting the spray assembly 7, while the air suction hood 61 and the air outlet hood 65 rotate with the driven rotating shaft 62, part of the water in the water tank 71 enters the interior of the spray ring 1 72 through the pipeline, and the atomizing nozzle 1 74 is started by the control module. The atomizing nozzle 1 74 installed at equal angles performs atomization spraying at the right end of the air suction hood 61, so that the exhaust gas passing through increases due to the air humidity, and the dust particles contained in the gas come into contact with the atomized water, thereby reducing the dust concentration in the gas. Part of the water in the water tank 71 enters the interior of the spray ring 2 73 through the pipeline, and the atomizing nozzle 2 75 is started by the control module. The atomizing nozzle 2 75 installed at equal angles performs atomization spraying at the right end outlet position of the air outlet hood 65, and the exhaust gas rotates to the right through the spiral groove 69 on the inner side of the air outlet hood 65. The exhaust gas is then drawn into the air at the tunnel entrance by the auxiliary fan 5. The exhaust gas is then drawn into the exhaust connecting pipe (not marked in the figure) under the auxiliary suction of the auxiliary fan 5 and discharged into the air at the tunnel entrance. Before the exhaust gas is subjected to dust particle adsorption and harmful gas filtering, the exhaust gas is sprayed with the atomizing nozzle 1 74 and the exhaust gas is sprayed with the atomizing nozzle 2 75. The atomized water increases the humidity in the exhaust gas, reduces the concentration of dust and impurities in the gas, prevents dust from being generated during gas treatment, and prevents pollution to the environment after the exhaust gas is discharged.

[0048] like Figure 5 and 7 to Figure 10 As shown, the adsorption component 8 includes an electrostatic generator 81, which is evenly distributed on the inner side of the side wall of the rotating shaft 62. There are four groups of electrostatic generators 81, each group of electrostatic generators 81 is symmetrically arranged on both sides of the rotating shaft 62, and each group of electrostatic generators 81 is symmetrically provided with two. The two ends of each electrostatic generator 81 are symmetrically connected to two power-on ends 82, and a mounting box 83 is connected between the two power-on ends 82. The power-on ends 82 are nested in the side wall of the mounting box 83, and the outer sides of the two power-on ends 82 are respectively provided with springs 84, which are connected to the ends of the corresponding power-on ends 82, and the tail ends of the springs 84 are connected to the ends of the corresponding power-on ends 82. On the inner wall of the mounting box 83, a counterweight block 85 is nested inside the mounting box 83, and the counterweight block 85 slides inside the mounting box 83. A contact block 86 is nested on one side of the mounting box 83, and the contact block 86 contacts the contact plate 87. The connecting ends of the two symmetrical contact plates 87 are respectively connected to the ends of two connecting rods 621 in the four connecting rods 621. The outer sides of the four groups of connecting rods 621 are sleeved with a synchronous wheel group 88. The end of one of the synchronous wheels in the synchronous wheel group 88 is connected to a bevel gear 89. The bevel gear 89 is meshed with a bevel gear plate 810. The bevel gear plate 810 is installed at the end of a pulley in the pulley group 63.

[0049] By setting the adsorption component 8, when the exhaust gas passes through the internal channel of the rotating shaft 62, the rotation of the rotating shaft 62 causes the electrostatic generator 81 located above to slide downward on the inner side of the mounting box 83 under the influence of its own gravity through the counterweight block 85 inside the mounting box 83. The two sides of the counterweight block 85 are in contact with the energized end 82, and the spring 84 is compressed by the force. The counterweight block 85 is connected with the energized end 82 on both sides, and the counterweight block 85 contacts the contact block 86 to transfer ions. The counterweight block 85 pushes the contact block 86 to contact the contact plate 87, and the contact plate 87 at the top transfers the ions to the two connected connecting rods 621. When the exhaust gas passes through, the two connecting rods 621 with ions adsorb dust particles in the exhaust gas through the principle of electrostatic adsorption, thereby reducing the dust content in the exhaust gas. At the same time, when the pulley group 63 rotates, it drives the bevel gear disc 810 to rotate, and the bevel gear disc 810 and the bevel gear 89 are meshed with each other. The wheel 89 drives the synchronous wheel set 88 connected to the end to rotate, and the synchronous wheel set 88 drives the connecting rod 621 to rotate accordingly, so that the connecting rod 621 can absorb dust while increasing the adsorption surface by self-rotation, thereby preventing the outer wall of the connecting rod 621 from being unable to adsorb dust due to excessive adsorption. When the rotating shaft 62 rotates to the bottom of the rotating shaft 62, the corresponding counterweight block 85 is affected by its own gravity and slides downward on the inside of the installation box 83, and the counterweight block 85 is disengaged from between the energized ends 82. The spring 84 pushes the corresponding energized end 82 back to its original position. The energized end 82 and the counterweight block 85 no longer form a path and cannot provide ions to the contact block 86 and the contact plate 87. At the same time, the contact block 86 is affected by gravity and no longer contacts the contact plate 87. The two connecting rods 621 connected to the contact plate 87 no longer have dust adsorption capacity, which facilitates the spherical activated carbon 68 to adsorb dust particles while vertically rolling inside the four connecting rods 621.

[0050] like Figures 1 to 10 As shown, a method for using an intelligent ventilation system for a high-altitude cold environment includes the following steps:

[0051] S1. The operator transports the intelligent ventilation equipment to the designated location using a carrier, connects the ventilation pipe to the end of the auxiliary fan 5, and starts the ventilator 1 and the auxiliary fan 5 during tunnel construction. Gas and dust are drawn in from the end of the ventilator 1 and into the dustproof box 2. Large dust particles in the gas are isolated by the dustproof net 3.

[0052] S2. Driven by the drive motor 64, the stirring rod 67 inside the storage box 66 stirs and mixes the spherical activated carbon 68 during rotation. The spherical activated carbon 68 enters the inner channel of the rotating shaft 62 through the connecting hole 620 on the side wall of the rotating shaft 62 and is located between the four connecting rods 621. The spherical activated carbon 68 is arranged equidistantly in the vertical direction. When the exhaust gas passes through the inner channel of the rotating shaft 62, the spherical activated carbon 68 located between the four connecting rods 621 adsorbs harmful substances in the exhaust gas. The spherical activated carbon 68 located between the four connecting rods 621 can be exchanged with the spherical activated carbon 68 inside the storage box 66 that is constantly stirred by the stirring rod 67 due to the rotation of the storage box 66.

[0053] S3. While the air suction hood 61 and the air outlet hood 65 rotate along with the driven rotating shaft 62, part of the water in the water tank 71 enters the interior of the spray ring 1 72 and the spray ring 2 73 through the pipe, and the atomizing nozzle 1 74 and the atomizing nozzle 2 75 are activated by the control module. The atomizing nozzle 1 74 installed at an equal angle distribution performs atomizing spraying at the right end of the air suction hood 61, and the atomizing nozzle 2 75 installed at an equal angle distribution performs atomizing spraying at the right end outlet position of the air outlet hood 65. The exhaust gas rotates to the right side through the spiral groove 69 inside the air outlet hood 65 and diverges, thereby reducing the pollution of the exhaust gas to the environment after discharge;

[0054] S4. When the exhaust gas passes through the internal channel of the rotating shaft 62, the two connecting rods 621 with ions absorb dust particles in the exhaust gas through the principle of electrostatic adsorption, thereby reducing the dust content in the exhaust gas. At the same time, when the pulley group 63 rotates, it drives the bevel gear 810 to rotate. The bevel gear 810 and the bevel gear 89 are engaged with each other. The bevel gear 89 drives the synchronous wheel group 88 connected at the end to rotate. The synchronous wheel group 88 drives the connecting rod 621 to rotate accordingly, so that the connecting rod 621 can increase the adsorption surface by self-rotation while adsorbing dust.

[0055] The working principle of the technical solution provided by the present invention is as follows:

[0056] The operator transports the intelligent ventilation equipment to the designated location through the carrying equipment, connects the ventilation pipe to the end of the auxiliary fan 5, and starts the ventilator 1 and the auxiliary fan 5 during tunnel construction. The gas and dust are sucked in from the end of the ventilator 1, and the gas enters the dust box 2. The large particles of dust in the gas are isolated by the dust net 3. The driving motor 64 is started, and the driving motor 64 drives the rotating shaft 62 to rotate through the pulley group 63. The air suction hood 61 and the air outlet hood 65 rotate with the driving rotating shaft 62. After the air flow enters the air suction hood 61, the spiral groove 69 on the inside of the air suction hood 61 rotates, causing the exhaust gas to gradually converge to the right end of the air suction hood 61, pass through the inner channel of the rotating shaft 62, and the storage box 66 rotates through the rotating shaft 62. The stirring rod 67 inside the storage box 66 rotates. The spherical activated carbon 68 is stirred and mixed, and enters the inner channel of the rotating shaft 62 through the connecting hole 620 on the side wall of the rotating shaft 62, and is located between the four connecting rods 621. The spherical activated carbon 68 is arranged equidistantly in the vertical direction. When the exhaust gas passes through the inner channel of the rotating shaft 62, the spherical activated carbon 68 located between the four connecting rods 621 adsorbs harmful substances in the exhaust gas. The spherical activated carbon 68 located between the four connecting rods 621 is exchanged with the spherical activated carbon 68 inside the storage box 66 that is always stirred by the stirring rod 67 during the rotation of the storage box 66, thereby improving the adsorption completeness of each spherical activated carbon 68, and avoiding the problem that a single spherical activated carbon 68 is always used to adsorb harmful substances, cannot be replaced and recycled, and has a short service life.

[0057] While the air suction hood 61 and the air outlet hood 65 rotate with the driven rotating shaft 62, part of the water in the water tank 71 enters the interior of the spray ring 1 72 through the pipeline, and the atomizing nozzle 1 74 is started by the control module. The atomizing nozzle 1 74 installed at equal angles performs atomization spraying at the right end of the air suction hood 61, so that the exhaust gas passing through increases due to the air humidity, and the dust particles contained in the gas come into contact with the atomized water, thereby reducing the dust concentration in the gas. Part of the water in the water tank 71 enters the interior of the spray ring 2 73 through the pipeline, and the atomizing nozzle 2 75 is started by the control module, etc. The angle-distributed atomizing nozzle 2 75 is installed to perform atomizing spraying at the right end outlet position of the air outlet hood 65. The exhaust gas rotates to the right side through the spiral groove 69 on the inner side of the air outlet hood 65 to diverge, thereby improving the contact effect with the atomized water sprayed by the atomizing nozzle 2 75, and further humidifying the exhaust gas after adsorbing harmful substances and dust, thereby reducing the concentration of dust and impurities contained in the gas, and reducing the pollution of the exhaust gas to the environment after discharge. Subsequently, the exhaust gas enters the exhaust connecting pipe (not marked in the figure) under the auxiliary suction of the auxiliary fan 5 and is discharged into the air at the tunnel entrance.

[0058] When the exhaust gas passes through the internal channel of the rotating shaft 62, the rotation of the rotating shaft 62 causes the electrostatic generator 81 located above to slide downward on the inner side of the mounting box 83 under the influence of its own gravity through the counterweight block 85 on the inner side of the mounting box 83. The counterweight block 85 contacts the energized end 82 on both sides, and the spring 84 is compressed by the force. The counterweight block 85 is connected to the energized end 82 on both sides, and the counterweight block 85 contacts the contact block 86 to transfer ions. The counterweight block 85 pushes the contact block 86 to contact the contact plate 87. The contact plate 87 at the top transfers the ions to the two connected connecting rods 621. When the exhaust gas passes through, the two connecting rods 621 with ions adsorb dust particles in the exhaust gas through the principle of electrostatic adsorption, thereby reducing the dust content in the exhaust gas. At the same time, when the pulley group 63 rotates, it drives the bevel gear 810 to rotate. The bevel gear 810 engages with the bevel gear 89, and the bevel gear 89 drives The synchronous wheel set 88 connected at the end rotates, and the synchronous wheel set 88 drives the connecting rod 621 to rotate accordingly, so that the connecting rod 621 can absorb dust while increasing the adsorption surface by self-rotation, thereby preventing the problem that the outer wall of the connecting rod 621 cannot absorb dust due to excessive adsorption. When the rotating shaft 62 rotates to the bottom of the rotating shaft 62, the corresponding counterweight block 85 is affected by its own gravity and slides downward on the inside of the installation box 83, and the counterweight block 85 is disengaged from between the energized ends 82. The spring 84 pushes the corresponding energized end 82 back to its original position. The energized end 82 and the counterweight block 85 no longer form a path and cannot provide ions to the contact block 86 and the contact plate 87. At the same time, the contact block 86 is affected by gravity and no longer contacts the contact plate 87. The two connecting rods 621 connected to the contact plate 87 no longer have dust adsorption capacity, which facilitates the spherical activated carbon 68 to adsorb dust particles while vertically rolling inside the four connecting rods 621.
