Description

Technical Field

[0001] The invention relates to the technical field of construction dust removal, and in particular to an environmentally friendly dust removal device and a dust removal method at a road construction site. Background Art

[0002] Road construction often generates a large amount of dust, which not only pollutes the construction area, but also spreads to surrounding areas with the wind direction, causing adverse effects on the atmospheric environment. Long-term high-concentration dust pollution will aggravate air pollution, affect air quality, and pose a potential threat to the ecological environment and biodiversity.

[0003] Most dust contains a variety of harmful substances, such as particulate matter (PM10, PM2.5), heavy metals, organic matter, etc., which have adverse effects on human health. Construction workers exposed to high-concentration dust environments for a long time are prone to health problems such as respiratory diseases and cardiovascular diseases. At the same time, surrounding residents and pedestrians may also be affected by dust pollution and damage their health. Therefore, environmentally friendly dust removal is an important measure to protect the health of construction workers and the public.

[0004] At present, many dust removal systems are equipped with several water pipes on the side of the protective wall, and atomizing nozzles are installed at intervals. Water flows through the water pipes and the atomizing nozzles to form water mist to remove dust around.

[0018] S3. The sprayed water mist reaches the air and combines with the dust particles in the air, making the particles heavier and finally falling to the ground to reduce dust.

[0019] The present invention has the following beneficial effects:

[0020] 1. The environmentally friendly dust removal device and dust removal method at the road construction site are equipped with an atomizing nozzle on the upper side of the water pipe body, so that after the water flows through the water pipe body and reaches the inside of the atomizing nozzle, the water can be sprayed out in the form of water mist. At the same time, the water flow is converted into water mist for spraying out, which can adsorb, wrap or condense the surrounding dust, increase its weight, and then settle to the ground under the action of gravity, thereby improving the air quality; not only that, in the process of spraying water mist, by pushing the cooperation of the cylinder, the state of the water mist spraying is made to move back and forth from top to bottom, so that the water mist can cover all heights more evenly, so the probability of dust particles being captured and settled by the water mist is also greatly increased.

[0021] 2. The environmentally friendly dust removal device and dust removal method at the road construction site, in the process of driving the atomizing nozzle to rise and fall by the pushing cylinder, the pushing cylinder cooperates with the tooth section provided on the side of the movable plate, so that a plurality of movable blocks change from a closed state to an open state, and from an open state to a closed state; when the pushing cylinder drives the atomizing nozzle to rise, a plurality of movable blocks change from an open state to a closed state, so that the water output of the upper pipe is limited, resulting in an increase in the water flow speed, thereby increasing the diffusion range of the water flow in the air, and can reach a farther range To reduce dust; when the air cylinder is pushed to drive the atomizing nozzle to descend, several movable blocks change from a closed state to an open state, which reduces the diffusion range of the water flow in the air and can remove the nearby dust. In this way, when the range is long and the height is high, the water flow can cover a wider area and can quickly suppress the diffusion of dust and prevent it from spreading to farther or lower areas. Not only that, by timely suppressing the diffusion of dust when the range is short and low, the secondary pollution of dust to the surrounding environment, air quality and residents' health can be reduced.

[0022] 3. The environmentally friendly dust removal device and dust removal method at the road construction site, in the process of pushing the movable end of the cylinder to rise and fall, the first pipe installed on the side of the connecting ring moves synchronously, so that the piston rod inserted and slidably fitted inside the first pipe uses the cooperation of the second track groove and the movable ball to reciprocate inside the first pipe. In the process of pushing the movable end of the cylinder to fall, the piston rod can absorb and collect the water flow in the lower pipe, and at the same time, the water volume can be limited, so as to avoid using too much water when the water outlet diameter changes as much as possible, thereby reducing unnecessary waste; not only that, when the cylinder is pushed to drive the atomizing nozzle to rise, the piston rod uses the cooperation of the second track groove and the movable ball to move toward the inner end of the first pipe and push the water flow inside the first pipe, thereby replenishing the water output, and at the same time, when the piston rod pushes the water flow inside the first pipe, the water pressure inside the atomizing nozzle is increased, the spray range is improved, and the problem of affecting the water output when the water outlet diameter becomes smaller is avoided as much as possible.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1: This embodiment is intended to promote the solution of many dust removal problems. Several water pipes are installed on the side of the protective wall, and atomizing nozzles are installed at intervals. Water flows through the water pipes and the atomizing nozzles to form water mist to remove dust around. However, the spray range of many atomizing nozzles is fixed, which makes it impossible to remove dust in different distances, affecting the dust removal effect. Please refer to Figure 1-Figure 9A road construction site environmental protection dust removal device and dust removal method, comprising a water pipe body 110, and an atomizing nozzle 120 installed at the upper end of the water pipe body 110, the water pipe body 110 is divided into a lower pipe 111 and an upper pipe 112, a first corrugated pipe 113 is installed on the upper side of the upper pipe 112, a connecting ring 114 is installed on the upper side of the first corrugated pipe 113, the connecting ring 114 is connected to the atomizing nozzle 120, a movable block 130 for controlling the flow rate of water flow is rotatably installed inside the upper pipe 112, a movable plate 131 and a movable plate 132 for guiding the moving path of the movable block 130 are installed inside the upper pipe 112, and the water pipe body 110 is installed on the side plate 230 On the side, the side plate 230 is installed with a pushing cylinder 140 for adjusting the movable height of the atomizing nozzle 120, and the outer side of the lower pipe 111 is symmetrically installed with a fixing ring 141 for connecting with the side plate 230, and the surface of the fixing ring 141 is symmetrically installed with bolts 142 for connecting with the side plate 230. It should be noted that a water pump is used on the bottom side of the water pipe body 110. The water pump is used for pumping water and supplying water in this solution. The water pump is a mechanical device for moving liquid (such as water). It transports the liquid from one place to another in various ways. Its specific model, working principle and usage are well known to those skilled in the art and will not be elaborated here.

[0035] See Figure 1 and Figure 2 In specific implementation, when the water flows through the lower pipe 111 and the upper pipe 112, the water flows through the atomizing nozzle 120 to form water mist and spray to the surroundings. Therefore, the water mist absorbs, wraps or condenses the dust particles in the surrounding air, increases their weight, and then settles to the ground under the action of gravity, thereby improving the air quality; by pushing the movable end of the cylinder 140 to extend and retract, the atomizing nozzle 120 moves up and down, so that the water mist can cover all heights more evenly during the spraying process, so the probability of dust particles being captured and settled by the water mist is also greatly increased.

[0036] This scheme also proposes an environmentally friendly dust removal method for road construction sites, including the following steps:

[0037] S1. Water flows through the pump and reaches the inside of the water pipe body 110;

[0038] S2. The water reaching the inside of the water pipe body 110 is ejected through the atomizing nozzle 120 to form a water mist;

[0039] S3. The sprayed water mist reaches the air and combines with the dust particles in the air, making the particles heavier and finally falling to the ground to reduce dust.

[0040] In the present embodiment: by installing an atomizing nozzle 120 on the upper side of the water pipe body 110, the water flow can be sprayed out in the form of water mist after passing through the water pipe body 110 and reaching the inside of the atomizing nozzle 120. At the same time, converting the water flow into water mist for spraying can adsorb, wrap or condense the dust particles in the surrounding air, increase their weight, and then settle to the ground under the action of gravity, thereby improving the air quality; not only that, in the process of spraying water mist, by pushing the cylinder 140, the state of water mist spraying is made to move back and forth from top to bottom, so that the water mist can cover all heights more evenly, so the probability of dust particles being captured and settled by water mist is also greatly increased.

[0041] Embodiment 2: This embodiment aims to solve the problem that the spray range of water mist is the same during the water mist process, so the dust near the wall may not be adsorbed, thus affecting the dust removal effect. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 9 A support rod 150 is installed on the side of the connecting ring 114, and a push rack 151 is installed on the bottom side of the support rod 150. The push rack 151 is in active contact with the movable plate 132. The movable plate 131 is fixedly installed on the inner wall of the upper pipe 112, and a first opening 160 for water flow is opened on the surface of the movable plate 131, and a first track groove 161 is opened on the upper side surface of the movable plate 131.

[0042] See Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 A tooth segment 162 is provided on the side of the movable plate 132, and the movable plate 132 is rotatably arranged inside the upper pipe 112. A movable groove 163 is installed on the side of the upper pipe 112. The tooth segment 162 is movably matched with the movable groove 163, and the tooth segment 162 is meshed with the pushing rack 151. The tooth segment 162 is set as a conical tooth segment. A plurality of transverse grooves 164 are provided on the surface of the movable plate 132. A sliding column 165 is installed on the upper side of the movable block 130, and a sliding block 170 is installed on the bottom side of the movable block 130. The sliding column 165 is slidably matched with the transverse groove 164, and the sliding block 170 is matched with the first track groove 161. A second opening 171 for circulating with water is provided on the surface of the movable plate 132.

[0043] See Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9In a specific implementation, when the push cylinder 140 drives the atomizing nozzle 120 to descend, the push rack 151 is engaged with the tooth segment 162 provided on the side of the movable plate 132, so that the movable plate 132 rotates by the cooperation of the push rack 151 and the tooth segment 162. During the rotation of the movable plate 132, the sliding column 165 installed on the upper side of the movable block 130 slides toward the other end of the transverse groove 164. At the same time, the sliding block 170 installed on the bottom side of the movable block 130 cooperates with the first track groove 161 to limit the moving track of the movable block 130, thereby realizing Several movable blocks 130 are changed from a closed state to an open state, thereby increasing the diameter of the water outlet of the upper pipe 112, causing the water flow velocity to decrease, thereby reducing the diffusion range of the water flow in the air, and falling faster due to the influence of gravity and air resistance, so the range of the water outlet becomes shorter; similarly, when the cylinder 140 is pushed to drive the atomizing nozzle 120 to rise, several movable blocks 130 are changed from an open state to a closed state, so the water output of the upper pipe 112 is restricted, resulting in an increase in the water flow velocity, thereby increasing the diffusion range of the water flow in the air, and dust can be reduced in a farther range.

[0044] In this embodiment: in the process of the atomizing nozzle 120 rising and falling by the push cylinder 140, the push cylinder 140 cooperates with the tooth segment 162 provided on the side of the movable plate 132, so that a plurality of movable blocks 130 change from a closed state to an open state, and from an open state to a closed state; when the push cylinder 140 drives the atomizing nozzle 120 to rise, a plurality of movable blocks 130 change from an open state to a closed state, so that the water output of the upper pipe 112 is limited, resulting in an increase in the water flow speed, thereby increasing the diffusion range of the water flow in the air, and dust can be reduced in a farther range; when the push cylinder 140 drives the atomizing nozzle 120 to descend, the plurality of movable blocks 130 change from an open state to a closed state, and thus the water output of the upper pipe 112 is limited, resulting in an increase in the water flow speed, thereby increasing the diffusion range of the water flow in the air, and dust can be reduced in a farther range; when the push cylinder 140 drives the atomizing nozzle 120 to descend, the plurality of movable blocks 130 change from an open state to a closed state, and thus dust can be reduced in a farther range. In the process, several movable blocks 130 change from a closed state to an open state, so that the diffusion range of the water flow in the air is reduced, and the dust that is closer can be removed. In this way, when the range is long and the height is high, the water flow can cover a wider area, and can quickly suppress the diffusion of dust and prevent it from spreading to farther or lower areas. Not only that, by timely suppressing the diffusion of dust when the range is short and low, the secondary pollution of dust to the surrounding environment, air quality and residents' health can be reduced. At the same time, by pushing the cylinder 140 to drive the atomizing nozzle 120 to rise and fall, the position of the atomizing nozzle 120 is different, so dust at different heights can be hit.

[0045] Embodiment 3: This embodiment aims to solve the problem that the water outlet diameter becomes smaller during the rising process of the atomizing nozzle, thereby affecting the water output and the dust removal efficiency. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 9A first pipe 180 is installed on the side of the connecting ring 114, and the movable end of the pushing cylinder 140 is connected to the upper side of the first pipe 180. A second bellows 181 is installed on the upper side of the lower pipe 111, and a second pipe 182 is installed on the upper side of the second bellows 181. The first pipe 180, the second bellows 181 and the second pipe 182 are connected.

[0046] See Figure 1 , Figure 2 , Figure 4 A piston rod 183 is inserted and slidably fitted inside the first pipe 180, a placement block 184 is installed on the side of the side plate 230, and a second track groove 185 for controlling the moving range of the piston rod 183 is opened on the side of the placement block 184. The cross-sectional shape of the second track groove 185 is set to be a circle with a flat cross section, and a movable ball 190 is installed on the side of the piston rod 183, and the movable ball 190 is slidably fitted with the second track groove 185.

[0047] See Figure 1 , Figure 2 , Figure 4 In the specific implementation, by pushing the movable end of the cylinder 140 downward, the first pipe 180 installed on the side of the connecting ring 114 moves synchronously, so that the piston rod 183 is inserted and slidably fitted inside the first pipe 180, and moves toward the outer end of the first pipe 180 by using the cooperation of the second track groove 185 and the movable ball 190. During the movement of the piston rod 183, the cooperation of the second bellows 181 and the second pipe 182 is used, and the piston rod 183 can absorb and collect the water flow in the lower pipe 111, and at the same time, the water volume can be limited to avoid the water outlet diameter as much as possible. In the enlarged state, excessive water is used to reduce unnecessary waste; not only that, when the cylinder 140 is pushed to drive the atomizing nozzle 120 to rise, the piston rod 183 uses the cooperation of the second track groove 185 and the movable ball 190 to move toward the inner end of the first pipe 180, and pushes the water flow inside the first pipe 180, thereby replenishing the water output. At the same time, the piston rod 183 pushes the water flow inside the first pipe 180 to increase the water pressure inside the atomizing nozzle 120, thereby improving the spray range and avoiding the problem of affecting the water output when the water outlet diameter becomes smaller.

[0048] See Figure 1 , Figure 2 , Figure 4A blocking plate 210 for blocking the water flow is rotatably installed at the connection between the first pipe 180 and the connecting ring 114. Rotating columns 211 are symmetrically installed on both sides of the blocking plate 210. The rotating columns 211 are rotatably matched with the inner wall of the first pipe 180, and a one-way torsion spring 212 is installed between the rotating columns 211 and the inner wall of the first pipe 180. A matching block 220 is installed on the side of the second pipe 182, and a sliding groove 222 is opened on the side of the side plate 230. The matching block 220 is slidably matched with the sliding groove 222.

[0049] See Figure 1 , Figure 2 , Figure 4 In a specific implementation, the blocking plate 210 and the one-way torsion spring 212 can be used to block the outlet of the first pipe 180 during the descent of the atomizing nozzle 120, and the blocking plate 210 is opened when the atomizing nozzle 120 is ascending, so that the water flow inside the first pipe 180 flows to the inside of the connecting ring 114 for water replenishment; through the setting of the one-way torsion spring 212, the blocking plate 210 will not move during the movement of the piston rod 183 toward the outer end of the first pipe 180, but the piston rod 183 will push the water flow inside the first pipe 180 during the movement toward the inner end of the first pipe 180, and use the water flow to push the blocking plate 210, so that the blocking plate 210 opens.

[0050] In this embodiment, during the process of pushing the movable end of the cylinder 140 up and down, the first pipe 180 installed on the side of the connecting ring 114 moves synchronously, so that the piston rod 183 inserted and slidably fitted inside the first pipe 180 uses the cooperation of the second track groove 185 and the movable ball 190 to reciprocate inside the first pipe 180. During the process of pushing the movable end of the cylinder 140 down, the piston rod 183 can absorb and collect the water flow in the lower pipe 111, and at the same time can limit the water volume, so as to avoid the water outlet from being used in the state where the diameter of the water outlet changes as much as possible. Use too much water and reduce unnecessary waste; not only that, when the cylinder 140 is pushed to drive the atomizing nozzle 120 to rise, the piston rod 183 uses the cooperation of the second track groove 185 and the movable ball 190 to move to the inner end of the first pipe 180, and pushes the water flow inside the first pipe 180, thereby replenishing the water output. At the same time, the piston rod 183 pushes the water flow inside the first pipe 180 to increase the water pressure inside the atomizing nozzle 120, thereby increasing the spray range and avoiding the problem of affecting the water output when the water outlet diameter becomes smaller as much as possible.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
