Description

Technical Field

[0001] This invention belongs to the field of environmental protection equipment technology, specifically a green dust reduction device for cement pole processing. Background Technology

[0002] As green production standards in the building materials industry continue to rise, the requirements for controlling fugitive dust in cement pole processing plants are becoming increasingly stringent. During the large-scale production of cement poles, numerous processes, from unloading and storing aggregates in open yards and conveyor belts to powder batching and forced mixing, continuously generate large amounts of aggregate dust and fine cement dust. Inadequate control not only fails to meet the air pollutant emission control requirements of the building materials industry but also deteriorates the workshop working environment and increases occupational health risks for frontline workers. Currently, atomized dust suppression is widely used for controlling fugitive dust in aggregate sheds, plant roads, and production workshops due to its flexible deployment and rapid dust suppression effect. This method uses water as a medium, requires no additional chemical consumables, and generates no secondary solid waste during the dust suppression process, aligning with the direction of green production control.

[0003] However, in the long-term operation of atomized dust suppression systems in cement pole processing scenarios, nozzle clogging has consistently been a key bottleneck restricting the stable operation of the system. Water used in cement pole factories is mostly drawn from municipal pipe networks or shallow groundwater, which generally carries silt and high levels of calcium and magnesium ions. In addition, cement dust and sand particles settling in the air in the dust suppression area are easily mixed into the water supply system with the falling water mist. The combined effect of these multiple impurities easily reduces the nozzle flow area. The micron-sized nozzles used in high-pressure micro-mist systems have extremely small orifice diameters, making them even less tolerant of impurities and more prone to clogging. In the early stages of nozzle clogging, the first symptoms are reduced water output and abnormal water patterns, such as dripping, larger mist particle size, and shortened spray range. This directly leads to a contraction of the mist coverage area, a significant decrease in the capture efficiency of fine dust, and a substantial reduction in dust suppression effect.

[0004] As operating time increases, the deposition and scaling of impurities inside the nozzles intensifies, gradually reducing the effective diameter of the nozzles and consequently decreasing the water output per nozzle. When the blockage reaches a critical level, the nozzles may become completely blocked and stop spraying water. When the water output pattern of the nozzles becomes abnormal or the nozzles become completely blocked, dust in the corresponding covered area will be uncontrolled, creating localized dust suppression blind spots. If these blind spots are not detected and cleared in time, the overall uniformity of dust suppression in the plant area will be disrupted, making it difficult to consistently achieve the required standards for fugitive emissions control. Furthermore, frequent nozzle clearing and replacement not only increases maintenance labor and consumable costs but also leads to intermittent shutdowns of the dust suppression system, making it difficult to guarantee continuous dust suppression throughout the entire production process. Summary of the Invention

[0014] The beneficial effects of this invention are as follows: 1. The green dust suppression equipment for cement pole processing described in this invention, when nozzle blockage leads to a reduction in water output, increases the water pressure between the push plate and the fixed plate. This causes the push plate to push the rotating shaft, moving and rotating simultaneously, thereby driving the entire ring pipe to rotate multiple nozzles. This replaces the blocked nozzles and allows unblocked nozzles to be connected to the liquid inlet in rotation. It can automatically switch to a backup nozzle when a single nozzle becomes blocked, alleviating problems caused by nozzle blockage such as dripping, enlarged mist particles, shortened range, and reduced mist coverage. This reduces the probability of localized dust suppression blind spots and helps maintain the stability of dust suppression effects in the plant area. Furthermore, this atomizing dust suppression mechanism can automatically respond to nozzle blockage faults based on water pressure changes, eliminating the need for manual real-time inspections and reducing the daily maintenance workload of the atomizing dust suppression system, thus extending the continuous operation time of the equipment. Additionally, the equipment can trigger an automatic switching mechanism for nozzle freezing in winter, improving the operational stability of the dust suppression system in low-temperature seasons and reducing interruptions in dust suppression function caused by freezing.

[0015] 2. The green dust suppression equipment for cement pole processing described in this invention, because the length of the circular block is less than the length of the rotating shaft, when the rotating shaft moves to its extreme left position, the circular block completely moves out from the right side of the column groove. The exposed circular block provides a direct physical reminder to the workers, indicating that the ring pipe has driven all the nozzles to rotate nearly one revolution, and all the nozzles are blocked, requiring timely maintenance. When the circular block moves completely to the right with the second horizontal plate, the rectangular rod completely disengages from the rectangular groove, and the circular block no longer blocks the vertical groove on the right side. The pressurized water on the left side of the fixed plate can enter the liquid channel through the vertical groove on the left side and then flow out through the vertical groove on the right side. The leakage phenomenon forms a secondary reminder, further reducing the probability of workers missing the warning.

[0016] 3. The green dust suppression equipment for cement pole processing described in this invention uses gas to purge the nozzles, combined with the active liquid squeezing action of the sliding disc, to effectively discharge residual water from the liquid chamber and nozzles. This helps reduce the deposition and scaling of impurities in the water inside the nozzles, and can also blow away some loose clogging impurities, reducing nozzle blockage. Furthermore, the venting and gas drying process reduces the risk of residual moisture freezing inside the nozzles in winter. Combined with the function of warm gas de-icing, it improves the equipment's adaptability to low-temperature environments and reduces the impact of nozzle freezing on the continuity of dust suppression operations.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 13 As shown, the green dust suppression equipment for cement pole processing according to the present invention, as an embodiment of the present invention, includes an atomizing dust suppression mechanism; the atomizing dust suppression mechanism includes a semi-circular block 1, and the top of the semi-circular block 1 is flat; an installation frame is fixed to the right side of the top of the semi-circular block 1; The outer surface of the semicircular block 1 is provided with an arc-shaped groove 11; an arc-shaped plate 12 is fixed above the arc-shaped groove 11; a ring tube 2 slides together inside the arc-shaped groove 11 and on the arc-shaped plate 12; The annular tube 2 has uniformly arranged partitions 21 fixed inside, and there is a liquid cavity between two adjacent partitions 21; each liquid cavity is equipped with a nozzle 22 on its outer ring, and the nozzle 22 is an atomizing nozzle 22; each liquid cavity is provided with a through hole 23 on its inner ring. The semicircular block 1 has a groove 13 inside, and the groove 13 passes through the left and right sides of the semicircular block 1; a fixing plate 14 is fixed on the right side inside the groove 13; an inlet pipe 15 is provided on the left side of the fixing plate 14, and the inlet pipe 15 extends to the bottom of the semicircular block 1; the water inlet volume of the inlet pipe 15 is the same as the water outlet volume of a single nozzle 22. A rectangular rod 16 is fixed on the fixed plate 14, and the rectangular rod 16 extends to the left side of the column groove 13; a push plate 17 slides on the rectangular rod 16, and the push plate 17 is connected to the fixed plate 14 by a spring. The push plate 17 has a liquid port 19 at the bottom of the column groove 13 on the left side. In the initial state, the liquid port 19 corresponds to the bottom through hole 23. A rotating shaft 3 is provided on the left side of the liquid port 19. A rotating cylinder 31 rotates inside the rotating shaft 3. The inner cavity of the rotating cylinder 31 is rectangular, and the rectangular rod 16 slides inside the rotating cylinder 31. The outer ring of the rotating shaft 3 is provided with a spiral groove 32; a sliding shaft 33 is fixed on one side of the column groove 13 near the left end of the semicircular block 1, and the sliding shaft 33 slides in the spiral groove 32. Two loop frames 34 are fixed on the left side of the rotating shaft 3; a ring 35 is fixed on the left side of the ring tube 2, and a long rod 36 is fixed on the ring 35, and the long rod 36 passes through the loop frame 34 and is slidably connected to the loop frame 34.

[0022] Before dust suppression operations are carried out, multiple sets of atomizing dust suppression mechanisms are first arranged at different dust suppression points in the cement pole processing plant area, such as sand and gravel stockpiles, conveying corridors, and main roads of the plant area. The atomizing dust suppression mechanism is fixedly installed through the mounting frame on the top of the semi-circular block 1, and the inlet pipe 15 is connected to the external water supply source to complete the equipment preparation work. Specifically, when dust suppression operations are required, an external water source is turned on, and water is continuously injected into the column groove 13 inside the semi-circular block 1 through the inlet pipe 15. A fixed plate 14 is fixed on the right side inside the column groove 13, and the water is stored in the chamber space between the fixed plate 14 and the push plate 17 under the obstruction of the fixed plate 14. As the water volume in the chamber gradually increases, the water pressure continues to rise and overcomes the initial elastic force of the spring, pushing the push plate 17 to slide to the left along the rectangular rod 16, and the spring is stretched synchronously. When the push plate 17 moves to the left of the liquid outlet 19, the chamber between the fixed plate 14 and the push plate 17 is connected to the through hole 23 at the bottom of the inner ring of the ring pipe 2 through the liquid outlet 19 at the bottom of the column groove 13. Evenly arranged partitions 21 are fixed inside the ring pipe 2, and there is an independent liquid chamber between two adjacent partitions 21. Water enters the corresponding liquid chamber through the through hole 23 and is finally atomized and sprayed outward by the atomizing nozzle 22 on the outer ring of the liquid chamber to achieve atomized dust suppression. Since the designed water inlet volume of the inlet pipe 15 is the same as the rated water outlet volume of a single nozzle 22, after the nozzle 22 stably outputs water, the water pressure and spring force in the chamber between the fixed plate 14 and the push plate 17 form a dynamic balance, the position of the push plate 17 remains relatively stable, and the equipment continues to maintain a stable dust suppression working state with a single nozzle 22. After the dust suppression operation is completed, the external water source is turned off, the water pressure between the fixed plate 14 and the push plate 17 gradually decreases, and the push plate 17 slides to the right and resets under the action of the spring's rebound force. The residual water in the chamber is pushed back by the push plate 17 and discharged through the inlet pipe 15, and the equipment returns to its initial state. More specifically, as the atomizing dust suppression mechanism operates for a long time, the nozzle 22, which is in operation, is affected by silt and impurities in the water, calcium and magnesium ion scaling, and the accumulation of settled dust. The flow area gradually shrinks, leading to progressive blockage. When the water output from the nozzle 22 gradually decreases due to blockage, the continuous water intake from the inlet pipe 15 disrupts the original water pressure balance between the fixed plate 14 and the push plate 17. The water volume in the chamber gradually increases, and the water pressure continues to rise, thus pushing the push plate 17 to continue moving to the left. The push plate 17 moves to the left until it is aligned with... After the ends of the rotating shaft 3 are engaged, they will continuously push the rotating shaft 3 to move synchronously to the left. Since the outer ring of the rotating shaft 3 has a spiral groove 32, and a sliding shaft 33 is fixed to the side of the column groove 13 near the left end of the semicircular block 1, the sliding shaft 33 slides within the spiral groove 32. Under the limiting and guiding action of the sliding shaft 33, the rotating shaft 3 moves linearly to the left while simultaneously rotating circumferentially. A rotating cylinder 31 rotates inside the rotating shaft 3. The inner cavity of the rotating cylinder 31 is rectangular, and the rotating cylinder 31 is sleeved on the outside of the rectangular rod 16. When the rotating shaft 3 rotates, it will move along... The rotating drum 31 rotates, and the rotating shaft 3 drives the rotating drum 31 to slide along the rectangular rod 16; the two loop frames 34 fixed on the left side of the rotating shaft 3 rotate synchronously with the rotating shaft 3 as they move to the left, and the rotation of the loop frames 34 drives the long rod 36 and the ring 35 to rotate synchronously; since the ring 35 is fixed on the left side of the ring tube 2, it drives the ring tube 2 to rotate along the arc groove 11 and the arc plate 12; during the rotation of the ring tube 2, the through hole 23 corresponding to the plug nozzle 22 originally aligned with the liquid outlet 19 gradually aligns with the liquid outlet 19. When the through hole 23 of the next adjacent liquid chamber rotates to a position completely aligned with the liquid outlet 19, the new nozzle 22 is connected to the water supply passage. At this time, the water output of the new nozzle 22 is rematched with the water inlet of the inlet pipe 15, the water pressure between the fixed plate 14 and the push plate 17 is restored to balance, the push plate 17 and the rotating shaft 3 stop moving, and switch to the working state of continuous dust suppression of the new nozzle 22. If the nozzle 22 connected later becomes blocked again, the equipment will repeat the above actions and automatically complete the next round of nozzle 22 replacement. Furthermore, when using the atomizing dust suppression mechanism in low-temperature winter conditions, if the water inside the nozzle 22 in the working position freezes, causing the nozzle 22 to become blocked and unable to discharge water, it will also cause a water pressure imbalance between the fixed plate 14 and the push plate 17, triggering the above-mentioned automatic switching process, controlling the ring pipe 2 to rotate and replace the blocked nozzle 22 with the spare nozzle 22, so that the equipment can still maintain the continuous operation of the dust suppression function under low-temperature conditions. Furthermore, when nozzle 22 becomes clogged, reducing its water output, the water pressure between push plate 17 and fixed plate 14 increases. This causes push plate 17 to push rotating shaft 3, moving and rotating it simultaneously. This, in turn, drives the ring pipe 2 to rotate multiple nozzles 22, replacing the clogged nozzles. Unclogged nozzles 22 are then rotated into the passage of inlet 19. This automatic switching to a backup nozzle 22 when a single nozzle 22 becomes clogged alleviates issues such as dripping, larger mist particles, shortened range, and reduced mist coverage caused by nozzle 22 clogging. This system addresses issues such as reduced coverage area and minimizes the probability of blind spots in dust suppression, helping to maintain the stability of dust suppression effects in the factory area. Furthermore, the atomizing dust suppression mechanism can automatically respond to nozzle 22 blockage faults based on water pressure changes, eliminating the need for real-time manual inspection and reducing the daily maintenance workload of the atomizing dust suppression system, thus extending the continuous operation time of the equipment. Additionally, in response to nozzle 22 freezing and blockage in winter, the equipment can trigger an automatic switching mechanism, which helps improve the operational stability of the dust suppression system in low-temperature seasons and reduces interruptions in dust suppression function caused by freezing and blockage.

[0023] As an embodiment of the present invention; a C-shaped chamber 4 is fixed on the arc plate 12, and the opening of the C-shaped chamber 4 faces the direction and does not block the bottom nozzle 22; The C-shaped compartment 4 has a gap between the side of the ring 35 and the arc plate 12, and the ring 35 passes through the gap and fits into the C-shaped compartment 4. In this embodiment, a partition 41 is provided between each of two adjacent nozzles 22, and the partition 41 is fixed on the annular tube 2; The partition 41 fits into the inner cavity of the C-shaped compartment 4; the ring 35 is also fixed on the partition 41.

[0024] During implementation, in the dust suppression process, the C-shaped chamber 4 fixed on the arc plate 12 cooperates with the ring pipe 2 to form a protective structure for the nozzle 22. The opening of the C-shaped chamber 4 faces downward, so it will not block the working nozzle 22 when it is rotated to the bottom, and can ensure that the nozzle 22 sprays dust normally. There is a gap between the side of the C-shaped chamber 4 near the ring 35 and the arc plate 12. The ring 35 passes through the gap and fits against the side wall of the C-shaped chamber 4. When the ring pipe 2 slides circumferentially along the arc groove 11 and the arc plate 12 to switch the nozzle 22, the ring pipe 2 will drive the ring 35 to rotate circumferentially along the side wall of the C-shaped chamber 4. Specifically, the C-type chamber 4 provides physical protection for the idle nozzles 22, preventing dust and sand from directly contacting the unused nozzles 22 and reducing the adhesion and deposition of external pollutants on the nozzle orifices and surfaces, thus lowering the probability of external blockage of the spare nozzles 22 during idle periods. Since each adjacent nozzle 22 is fixed with a partition 41, which rotates synchronously with the ring pipe 2 and whose outer surface is in contact with the inner wall of the C-type chamber 4, the partition 41 forms multiple dynamic partitions within the C-type chamber 4. This creates a continuous sealed barrier at the opening of the C-type chamber 4, preventing external dust from entering the chamber and spreading inwards, thus avoiding large-scale dust accumulation inside the C-type chamber 4 and contaminating multiple sets of spare nozzles 22, further enhancing the protection of the idle nozzles 22 deep within the chamber.

In this embodiment, a support plate 18 is fixed to the right side of the push plate 17, and the top of the support plate 18 is in contact with the column groove 13; In this embodiment, a gear 56 is rotatably mounted above the support plate 18 on the inner wall of the semicircular block 1; A second transverse groove is provided below the gear 56, and a second transverse plate 6 slides in the second transverse groove, and the second transverse plate 6 extends to the right side of the semicircular block 1; a circular block 61 slides on the right side of the fixed plate 14, and the circular block 61 is fixed on the second transverse plate 6 by a connecting plate; the length of the circular block 61 is less than the length of the rotating shaft 3.

[0026] During implementation, in the initial state, the spring between the n-shaped frame 55 and the slider 53 applies a downward elastic force to the slider 53, causing the top surface of the notch 54 on the slider 53 to fit against the top of the first horizontal plate 51; the locking teeth on the top surface of the notch 54 engage with the locking groove on the top of the first horizontal plate 51, thus limiting the first horizontal plate 51; since the locking plate 52 fixed on the left side of the first horizontal plate 51 slides in the groove of the annular plate 5, and the annular plate 5 is fixed on the outer ring surface of the rotating shaft 3, the constraint of the first horizontal plate 51 and the locking plate 52 can fix the rotating shaft 3, preventing the rotating shaft 3 from unexpectedly moving axially or rotating circumferentially when the atomizing dust suppression mechanism is not in operation, during transportation or storage, and ensuring the initial position stability of the ring tube 2 and the nozzle 22; a protective cover can be installed on the outside of the slider 53 and the n-shaped frame 55 to protect the internal sliding pair and elastic structure, preventing dust from the factory area from entering the interior of the chute and reducing the risk of structural jamming; Specifically, when the atomizing dust suppression mechanism starts dust suppression operation, water pressure pushes the push plate 17 to move to the left along the rectangular rod 16. As the push plate 17 passes the liquid inlet 19, the top of the push plate 17 contacts the rounded corner structure at the bottom of the slider 53. As the push plate 17 continues to move to the left, the push plate 17 pushes the slider 53 upward along the slide groove through the guiding effect of the rounded corner, compressing the spring between the n-shaped frame 55 and the slider 53. When the push plate 17 moves to the stable working position on the left side of the liquid inlet 19, the main body of the push plate 17 is directly below the slider 53, and the slider 53 is pushed by the push plate 17. When raised to a high position, the notch 54 moves upward synchronously with the slider 53. The top surface of the notch 54 separates from the top of the first horizontal plate 51, and the locking teeth disengage from the locking groove, releasing the limiting constraint on the first horizontal plate 51. At this time, if the nozzle 22 is blocked, the water pressure increases and pushes the push plate 17 to continue to move to the left and drives the rotating shaft 3 to move synchronously. The rotating shaft 3 can drive the annular plate 5 to rotate synchronously, and the groove slides along the circumference of the locking plate 52. At the same time, the rotating shaft 3 can drive the first horizontal plate 51 to slide to the left along the first horizontal groove through the annular plate 5 and the locking plate 52, without interfering with the automatic replacement process of the nozzle 22. Since the push plate 17 is fixed with a support plate 18 on the right side, and the top of the support plate 18 is in contact with the inner wall of the column groove 13; when the push plate 17 pushes the rotating shaft 3 to move to the left to the left side of the slider 53, the support plate 18 moves synchronously with the push plate 17 to the bottom of the slider 53, continuously supporting the slider 53, keeping the slider 53 in the unlocked state of moving upward, and preventing the slider 53 from falling and resetting and locking the first horizontal plate 51 again, ensuring that the limiting mechanism is always in the unlocked state during the continuous switching of the nozzle 22; More specifically, as the nozzle 22 becomes gradually clogged with prolonged use, the rotating shaft 3 continuously moves to the left. Through the cooperation of the annular plate 5, the groove, and the retaining plate 52, the rotating shaft 3 drives the first horizontal plate 51 to slide continuously to the left along the first horizontal groove. Since both the first horizontal plate 51 and the second horizontal plate 6 have toothed grooves 62 on the side facing the gear 56, and these grooves 62 mesh with the gear 56, the movement of the first horizontal plate 51 to the left drives the gear 56 to rotate, thereby driving the second horizontal plate 6 to move to the right along the second horizontal groove. Plate 6 drives the round block 61 to slide to the right along the right side surface of the fixed plate 14 via the connecting plate, so that the round block 61 gradually moves out from the right end face of the column groove 13. Since the length of the round block 61 is less than the length of the rotating shaft 3, when the rotating shaft 3 moves to the left to the limit position, the round block 61 completely moves out from the right side of the column groove 13. The exposed round block 61 can provide a direct physical reminder to the staff, indicating that the ring pipe 2 has driven all the nozzles 22 to rotate nearly one revolution, and all the nozzles 22 are blocked and need to be maintained in time. Furthermore, since a liquid channel 63 is provided inside the rectangular rod 16, and vertical grooves 64 are provided on both sides of the liquid channel 63, the vertical grooves 64 penetrate the top and bottom of the rectangular rod 16; in the initial state, the rectangular rod 16 is inserted into the rectangular groove of the circular block 61, and the inner wall of the circular block 61 blocks the vertical groove 64, so the liquid channel 63 is in a closed state; when the circular block 61 moves completely to the right with the second horizontal plate 6, the rectangular rod 16 completely detaches from the rectangular groove, and the circular block 61 no longer blocks the vertical groove 64 on the right side. The pressurized water on the left side of the fixed plate 14 can enter the liquid channel 63 through the vertical groove 64 on the left side, and then flow out through the vertical groove 64 on the right side. The leakage phenomenon forms a secondary reminder, further reducing the probability of the staff missing the warning; after receiving the reminder, the staff can clean or replace all the nozzles 22 in time, and after resetting the equipment, the dust suppression operation can continue.

[0027] As an embodiment of the present invention; an air groove 7 is provided inside the semi-circular block 1, and the air groove 7 is connected to an external air pipe; The air groove 7 is provided with an air hole 72, and the air hole 72 is aligned with the next through hole 23 that rotates clockwise from the bottommost through hole 23. The C-shaped compartment 4 has a slot, and an arc-shaped cover 73 is rotated on the slot by a torsion spring; In this embodiment, a sliding plate 74 is provided between two adjacent partition plates 21, and the sliding plate 74 and the partition plate 21 are connected by a spring. The slide plate 74 contacts both sides of the nozzle 22 under the action of the spring.

[0028] During implementation, when the clogged nozzle 22 is replaced by a new nozzle 22 after the ring pipe 2 rotates, the original clogged nozzle 22 continues to rotate clockwise with the ring pipe 2, gradually moving to the position corresponding to the air hole 72, so that the inner ring through hole 23 of the liquid chamber corresponding to the nozzle 22 is completely aligned with the air hole 72 on the air groove 7; at this time, gas can be introduced into the air groove 7 in the semi-circular block 1 through the external air pipe. After the gas is guided by the air groove 7, it enters the liquid chamber through the air hole 72 and the corresponding through hole 23, purging the liquid chamber and the nozzle 22; the water remaining in the liquid chamber... Under the action of air pressure, the gas is gradually pushed towards the nozzle 22 and discharged outward. After the residual water is discharged, the gas continues to be sprayed outward through the nozzle 22. The C-type chamber 4 is provided with a slot, and an arc-shaped cover 73 is rotated on the slot by a torsion spring. The outward force generated by the nozzle 22 spraying water or air can open the arc-shaped cover 73, so that the water and gas can be discharged smoothly to the outside. In the non-purge state, the arc-shaped cover 73 is kept closed by the reset force of the torsion spring, which can prevent dust floating in the factory area from entering the slot and reduce the secondary pollution of the idle nozzle 22 by dust. Specifically, a sliding plate 74 is provided between two adjacent partitions 21, and the sliding plate 74 and the partition 21 are connected by a spring. When the nozzle 22 is in the working water supply state, the water pressure in the liquid chamber can push the sliding plate 74 to compress the spring, so that the nozzle 22 can normally atomize water. When the nozzle 22 rotates with the ring pipe 2 to disengage from the liquid port 19 and stops supplying water, the water pressure in the liquid chamber disappears, and the sliding plate 74 moves to one side of the nozzle 22 under the elastic force of the spring. It can actively squeeze most of the residual liquid in the liquid chamber toward the nozzle 22 and discharge it, greatly reducing the amount of residual liquid in the liquid chamber. The compressed gas that is then introduced can further blow away the remaining residual liquid and loose impurities attached to the flow channel, and blow out the residual water and the accumulated mud and sand impurities together through the nozzle 22. More specifically, when used in low-temperature conditions in winter, warm gas can be introduced into the air tank 7. The warm gas enters the liquid chamber and the inside of the nozzle 22 through the air hole 72 and the through hole 23. If there is ice blockage inside the nozzle 22, the warm gas can gradually melt the internal ice layer and relieve the frozen state of the nozzle 22. Furthermore, by blowing gas through the nozzle 22, combined with the active liquid squeezing action of the sliding plate 74, the residual water in the liquid chamber and nozzle 22 can be discharged more thoroughly. This helps to reduce the deposition and scaling of impurities in the water inside the nozzle 22, and can also blow away some loose clogging impurities, reducing the clogging of the nozzle 22. At the same time, the venting and gas drying action can reduce the risk of residual moisture inside the nozzle 22 freezing in winter. Combined with the function of warm gas to melt ice, it can improve the equipment's adaptability to operation in low-temperature environments and reduce the impact of nozzle 22 freezing on the continuity of dust suppression operations.

[0029] As one embodiment of the present invention; the inlet pipe 15 is an inverted Y-shaped pipe, and the bottom of the inlet pipe 15 is provided with two inlets; A metering assembly is installed at the bottom of the inlet pipe 15; the metering assembly includes a liquid tank 8. A liquid tank 8 is fixed at the bottom of the inlet pipe 15; a fixing block 81 is fixed inside the liquid tank 8, and two circular grooves 82 are opened on the fixing block 81; two piston discs 83 slide in each of the two circular grooves 82, one piston disc 83 is located at the top of one of the circular grooves 82, and the other piston disc 83 is located at the bottom of the other circular groove 82; a one-way valve is installed on each of the piston discs 83. Two electric actuators 84 are installed at the bottom of the liquid tank 8, and the extension rods 36 of the electric actuators 84 are respectively connected to two piston discs 83; an inlet pipe is connected to the liquid tank 8; a filter screen 85 is installed below the fixing block 81, and the filter screen 85 is located above the inlet pipe; the extension rods 36 of the electric actuators 84 pass through the filter screen 85.

[0030] In practice, the inlet pipe 15 is configured as an inverted Y-pipe with two inlets at its bottom, and two circular grooves 82 are connected to the two inlets of the inverted Y-pipe respectively; a piston disc 83 slides in each of the two circular grooves 82, and the two piston discs 83 are staggered, with one piston disc 83 located at the top of one circular groove 82 and the other piston disc 83 located at the bottom of the other circular groove 82; a one-way valve is installed on each piston disc 83, and the one-way valve only allows water to flow unidirectionally from the bottom of the piston disc 83 to the top of the piston disc 83; Specifically, during dust suppression operations, external water is injected into the liquid tank 8 through the inlet pipe. After passing through the filter screen 85, the water flows upward and gradually fills the space of the liquid tank 8 below the fixed block 81. The inlet pipe continuously supplies water to keep the liquid tank 8 full of water. Then, the two electric actuators 84 are controlled to extend and retract alternately, driving the two piston discs 83 to slide back and forth in the corresponding circular grooves 82. When one of the electric actuators 84 drives the piston disc 83 to move downward, the piston disc 83 squeezes the water below it. Under pressure, the one-way valve opens, and the piston in the circular groove 82... Water below the piston disc 83 flows into the chamber above the piston disc 83 through a one-way valve. When the electric actuator 84 on this side moves the piston disc 83 upward, the one-way valve automatically closes under reverse water pressure. Water above the piston disc 83 cannot flow back to below the piston disc 83. As the piston disc 83 moves upward, it is pushed into the inlet corresponding to the inverted Y pipe and finally injected into the column groove 13 inside the semi-circular block 1 through the inlet pipe 15. The two piston discs 83 alternate up and down in a cycle, which can continuously push the water in the circular groove 82 into the column groove 13, maintaining a stable water supply. More specifically, since the internal volume of the circular groove 82 is fixed, the maximum amount of water pushed by a single piston disc 83 in a single upward stroke is equal to the single-stroke volume of the circular groove 82. This allows control over the total amount of water entering the column groove 13 per unit time, ensuring that the water inflow matches the rated output of a single nozzle 22. If the equipment is directly connected to an external water source, fluctuations in the upstream water pressure will cause an abnormal increase in the amount of water entering the column groove 13, resulting in an abnormal increase in water pressure between the fixed disc 14 and the push disc 17. This will push the push disc 17 to the left and trigger the rotation of the shaft 3, creating a false triggering action that causes the nozzle 22 to become blocked. By limiting the upper limit of the water inflow through the volume of the circular groove 82 of the metering component, the influence of upstream water pressure fluctuations on the water inflow in the column groove 13 can be isolated, preventing the nozzle 22 from switching erroneously due to water pressure fluctuations. Furthermore, since the filter screen 85 is located between the inlet pipe and the fixed block 81, the external water supply must pass through the filter screen 85 before entering the circular groove 82 and the column groove 13 after entering the liquid tank 8. This allows for pre-filtration and interception of silt and suspended impurities in the water, effectively reducing the impurity content entering the column groove 13, the liquid chamber, and the nozzle 22, and reducing the problem of nozzle 22 blockage caused by impurity accumulation. After the dust suppression operation is completed, the two electric push rods 84 are controlled to retract synchronously, driving the two piston discs 83 to move downwards to the bottom position of the circular groove 82, so that the piston discs 83 and the bottom of the circular groove 82 maintain a distance, and the circular groove 82 is connected to the space of the liquid tank 8 below. At this time, the water remaining in the column groove 13 flows back into the two circular grooves 82 through the inlet pipe 15, and then flows downwards to the lower space of the liquid tank 8, and finally flows back out through the inlet pipe, realizing the emptying of the column groove 13 and the water inlet pipe, and reducing the residual water in the pipe. Furthermore, by having two piston discs 83 move up and down alternately, and limiting the maximum water intake volume at a time with the fixed volume of the circular groove 82, the influence of upstream water pressure fluctuations can be effectively isolated, ensuring a stable match between the water intake volume and the water output volume of a single nozzle 22, and reducing the probability of nozzle 22 erroneous switching or false blockage caused by water pressure fluctuations. At the same time, by using two staggered piston discs 83 to deliver water alternately, continuous and uninterrupted water supply can be achieved, avoiding the water supply intermittent problem of single piston structure, which helps to ensure the continuous stability of nozzle 22 atomization and dust suppression.
