Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, and particularly relates to a building engineering dust control device. BACKGROUND

[0002] Building engineering dust control is an important link in preventing and treating air pollution. The existing building engineering dust control mainly relies on water mist sprayed by a spray gun to combine with dust in the air to achieve dust reduction, thereby achieving the effect of dust control.

[0003] A building engineering dust control spraying device is disclosed in Chinese Patent No. CN214019883U; the device comprises a servo motor, a servo cylinder, an inclined nozzle, a bearing, a baffle, and a storage bin. The servo motor allows the inclined nozzle to rotate and spray, so that the sprayed water mist is uniformly diffused. The servo cylinder controls the up-and-down movement of the inclined nozzle, so that dust can be sprayed and suppressed in a larger range. The baffle and the storage bin can protect the inclined nozzle and the water inlet pipe after the spraying device is used, so as to prevent dust that has not been completely removed from the air from being adsorbed on the inclined nozzle or the water inlet pipe, thereby preventing blockage.

[0004] However, the above-mentioned prior art has the following defects: in a strong wind environment, the water mist is easily blown away from the target area, and the effective coverage area of the fog gun is further reduced due to the strong wind (a fog gun with a range of 30 m covers about 700 square meters in the absence of wind, and only 200 square meters in an 8-level wind), which reduces the dust reduction effect. In addition, strong winds can accelerate the evaporation of water mist, further reducing the dust reduction effect, thereby significantly reducing the dust control effect of the above-mentioned prior art in a strong wind environment.

[0029] Example 1, as Figures 1-5 As shown, the present invention proposes a dust control device for construction projects, comprising an atomizing mechanism, a counter-wind mechanism, and a moving mechanism;

[0030] The atomizing mechanism includes cylinder a2, cylinder b19, mesh plate 3, water tank 28, submersible pump, nozzle 11, pipe a10, adjustment assembly, and reflux assembly; cylinder b19 is inserted into one end of cylinder a2, and the inner surface of cylinder a2 is provided with inner rubber pleats; the outer surface of cylinder b19 is provided with outer rubber pleats. The cooperation of the inner and outer rubber pleats ensures the sealing of the connection between cylinder a2 and cylinder b19 (during the insertion of cylinder a2 and cylinder b19, both the inner and outer rubber pleats will change). Deformation ensures that the cylinder b19 can be inserted into the inside of the cylinder a2; the mesh plate 3 is located at the other end of the cylinder a2. The mesh plate 3 is a concave windbreak and dust suppression mesh, used to reduce the wind speed entering the cylinder a2 (when the wind directly hits the concave surface, some of the kinetic energy is converted into pressure energy, thereby reducing the wind speed. At the same time, the wind force is reflected or rubbed multiple times on the inner side of the concave surface to reduce the wind speed); the cylinder a2 has multiple circumferentially distributed openings; the nozzle 11 is rotatably located inside the opening and connected to the opening through the elastic membrane 13 (the nozzle 11 is a BETE). The TF series mechanically adjustable nozzle (which can adjust the droplet size) features an elastic membrane 13 that ensures the nozzle 11 can rotate freely within the opening while maintaining its airtightness. Pipe a10 (an annular pipe) is connected to the nozzle 11 via an adjusting assembly, and pipe a10 and nozzle 11 are interconnected. A recirculation assembly on cylinder b19 reverses the airflow to reduce wind speed. The recirculation assembly includes a motor a23, pipe c24, and pipe d7. Pipe c24 is rotatably connected to cylinder b19. Multiple pipes d7 are provided and connected to pipe c24 (pipe d7 is a rigid metal tube). Pipe c24 is inserted into pipe b4. Motor a23 is connected to pipe c24 via a transmission (pipe c24 has a gear d, and the output end of motor a23 has a gear e that meshes with gear d). A water tank 28 is located on cylinder a2. A submersible pump is located inside the water tank 28 and is connected to pipe a10.

[0031] The counter-wind mechanism is composed of a plate a14, a plate b, a tube b4, a fan plate 5, a gear a8 and a gear ring 6. The plate a14 is arranged on the surface of the cylinder a2 and is annular. The plate b is arranged on the surface of the plate a14 and is annular. The tube b4 is connected with the plate b. The fan plate 5 is arranged on the surface of the tube b4 and is annular. The gear a8 is connected with the tube b4. The gear ring 6 is arranged on the surface of the cylinder a2 and is engaged with the gear a8.

[0032] The moving mechanism is connected with the atomizing mechanism and is used to drive the atomizing mechanism to move. The moving mode of the moving mechanism includes but is not limited to pulling the walking robot to move.

[0033] It should be noted that the device is suitable for point source dust (such as the outlet of a crusher or a loading point). The device can be set to be used simultaneously according to requirements.

[0034] In this embodiment, in strong wind, the wind direction is first determined, and then the moving mechanism is used to drive the atomizing mechanism to move to face the wind direction (i.e. to make the screen plate 3 face the wind direction). When the strong wind blows the dust to the screen plate 3, part of the kinetic energy of the strong wind is converted into pressure energy, which plays a role in reducing the wind speed. When the strong wind carrying the dust passes through the screen plate 3 and enters the inside of the cylinder a2, the water in the water tank 28 is first delivered to the tube a10 under the action of the submersible pump, and then delivered to the spray head 11 by the tube a10, and finally atomized and sprayed out by the spray head 11. Since the spray head 11 is circumferentially distributed, the water mist sprayed by each spray head 11 forms a water mist wall. Since the wind speed entering the cylinder a2 is significantly reduced, the penetration of the dust it carries is significantly reduced, which ensures that the water mist wall can fully contact the dust, realizes the dust reduction function (the dust reduction material or sewage formed by the combination of dust and water mist will be left in the inside of the cylinder a2 and the cylinder b19, and the sewage will also flow out through the holes in the screen plate 3 and fall into the recovery tank 1 when there is too much sewage), and the dust entering the cylinder a2 will not continue to spread, which ensures the effectiveness of dust cleaning. Finally, the air entering the cylinder a2 passes through the tube c24 into each tube d7, and is finally blown out in the reverse direction by the tube d7, thereby playing a role in offsetting part of the wind force. At the same time, the motor a23 is started, the motor a23 drives the tube c24 to rotate, the tube c24 drives each tube d7 to move in a circular motion, the tube d7 drives the tube b4 to move in a circular motion, the tube b4 drives the gear a8 to roll along the gear ring 6, the gear a8 drives the tube b4 to rotate, the tube b4 drives the fan plate 5 to rotate, and the reverse wind force is generated to offset part of the wind force, realize the function of reducing the wind speed, and further reduce the flow rate (wind speed) of the airflow entering the cylinder a2.

[0035] In windless or lightly windy conditions, cylinders a2 and b19 can be separated, cylinder a2 can be rotated 90 degrees, and the screen 3 can be set downwards. Then, the nozzle 11 can be set upwards using the adjustment component. At this time, the water mist sprayed from the nozzle 11 will spray upwards and diffuse into the air, combining with the dust in the air. The resulting dust will fall back into the inside of cylinder a2 (some of the dust will pass through the screen 3 and fall into the recycling pool 1).

[0036] After dust control is completed, the adjustment component can be used to drive the nozzle 11 to swing back and forth, and at the same time the size of the droplets sprayed by the nozzle 11 can be adjusted to the maximum, so that the nozzle 11 can rinse the inside of cylinder a2 and cylinder b19, and realize the cleaning function of the inside of cylinder a2 and cylinder b19.

[0037] Example 2, as Figures 2-4 As shown, the dust control equipment for construction projects proposed in this invention, compared with Embodiment 1, further details the structure of the adjustment component. The adjustment component includes a plate c9, a telescopic component a15, a ring a16, a ring b17, and a ring c18; the plate c9 is connected to the cylinder a2; the telescopic component a15 is disposed on the plate c9 and connected to the pipe a10 (the telescopic component a15 includes, but is not limited to, devices such as cylinders); multiple rings a16 are provided and sleeved on the pipe a10; the ring b17 is slidably disposed on the surface of the nozzle 11; the ring b17 is connected to the ring a16; the ring c18 is connected to the nozzle 11 and serves to limit the sliding of the ring b17.

[0038] In this embodiment, the telescopic component a15 pushes the tube a10 toward the toothed ring 6. The tube a10 drives the ring b17 to rotate through the ring a16. The ring b17 drives the nozzle 11 to rotate (at the same time, the ring b17 slides on the surface of the nozzle 11 for distance compensation), so that the nozzle 11 is obliquely positioned and points to the opening of the cylinder a2 (i.e., the end where the folded cloth 12 is located). Conversely, when the telescopic component a15 drives the tube a10 to move toward the plate c9, the nozzle 11 will tilt and point toward the mesh plate 3. When the telescopic component a15 drives the tube a10 to move back and forth, the reciprocating swing function of the nozzle 11 can be realized.

[0039] It is worth noting that pipe a10 is connected to nozzle 11 via a telescopic flexible hose, which facilitates distance compensation during the rotation of nozzle 11.

[0040] Example 3, as Figure 6As shown, the dust control equipment for construction projects proposed in this invention, compared with Embodiment 2, further details the structure of the flow guiding component. The flow guiding component is provided on the plate c9, and includes a telescopic component b27, a housing 26, a sliding rod 25, and a folded cloth 12. The housing 26 has multiple components arranged circumferentially on the plate c9 in an inclined state. The telescopic component b27 is located inside the housing 26 (the telescopic component b27 includes, but is not limited to, devices such as cylinders). The sliding rod 25 is slidably located inside the housing 26 and connected to the telescopic component b27. The folded cloth 12 is annular and one end is connected to the sliding rod 25 (the folded cloth 12 is a waterproof cloth, which is a fabric that has undergone special treatment or is made of waterproof materials and has functions such as moisture-proof, water-proof, and water-repellent). The other end of the folded cloth 12 is connected to the housing 26.

[0041] In this embodiment, the telescopic component b27 is used to push the slide bar 25 to move, and the slide bar 25 drives one end of the folded cloth 12 to move, thereby changing it from a folded state to an unfolded state, increasing the overall area. This can guide the falling dust and ensure that most of the dust and debris can fall back into the cylinder a2, reducing the amount of sediment returning to the ground and improving the dust cleaning effect.

[0042] Example 4, as Figure 7 As shown, this invention proposes a dust control device for construction projects. Compared to Embodiment 3, this embodiment further details the structure of the moving mechanism. The moving mechanism includes a recycling tank 1, a plate d102, a motor b20, a motor c22, a lead screw, a sliding plate, a guide rod, and a plate e21. The bottom of the recycling tank 1 is equipped with casters, and a door panel 101 is provided on the recycling tank 1 for cleaning dust and wastewater inside the recycling tank 1. When it is necessary to clean the wastewater and dust in the recycling tank 1, the door panel 101 can be opened to facilitate workers to enter the recycling tank 1 for cleaning operations. Two plates d102 are provided and connected to the recycling tank 1. The motor b20 is located on the plate d102. The motor d102 is connected to the cylinder a2 via a rotating shaft and is rotatably connected to the plate d102. One end of the rotating shaft is connected to a gear b. The output end of the motor b20 is connected to a gear c that meshes with the gear b. Two chute plates are provided and connected to the recycling pool 1. A lead screw and a guide rod are rotatably provided on the inner side of the two chute plates respectively. Two plates e21 are provided and connected to the cylinder b19. A nut block is provided at the bottom end of one plate e21. The nut block is threadedly connected to the lead screw and slidably connected to the chute plate. The bottom end of the other plate e21 is slidably connected to the guide rod via a slider. The slider is slidably connected to the chute plate. The motor c22 is located on the recycling pool 1 and its output end is connected to the lead screw.

[0043] In this embodiment, the motor b20 drives the gear c to rotate, the gear c drives the gear b to rotate, the gear b drives the cylinder a2 to rotate through the rotating shaft, so that the cylinder a2 rotates 90 degrees, ensures that the screen plate 3 is set downward, facilitates the water mist sprayed by the nozzle 11 to diffuse to the external environment; the motor c22 drives the screw rod to rotate, the screw rod drives the nut block to move away from the cylinder a2 along the sliding groove plate (the bottom end of the nut block and the sliding block is provided with a plurality of balls, which can reduce the friction between them and the sliding groove plate), the nut block drives the cylinder b19 away from the cylinder a2 through the plate e21, so that the two are separated from each other, facilitating the subsequent angle adjustment of the cylinder a2.

[0044] In summary, when encountering strong wind weather, the device is transferred to the point source dust source (such as the outlet of the crusher, the loading point) by the moving mechanism, the wind direction is judged, and the screen plate 3 is set to face the wind direction. When the strong wind blows the dust to the screen plate 3, part of the kinetic energy of the strong wind is converted into pressure energy, which plays a role in reducing the wind speed. After the strong wind carrying the dust passes through the screen plate 3 into the inside of the cylinder a2, under the action of the submersible pump, the water in the water tank 28 is first delivered to the pipe a10, and then delivered to the nozzle 11 from the pipe a10, and finally atomized and sprayed out from the nozzle 11. Due to the circumferential distribution of the nozzle 11, a wall of water mist is formed by the water mist sprayed by each nozzle 11. Due to the significant decrease in wind speed entering the cylinder a2, the penetration force of the dust it carries is significantly reduced, ensuring that the water mist wall can fully contact the dust, realizing the dust reduction function (the dust reduction material or sewage formed after the dust combines with the water mist will remain inside the cylinder a2 and the cylinder b19, and when there is too much sewage, it will also flow out through the holes on the screen plate 3 and fall into the recovery tank 1). The dust entering the cylinder a2 will not continue to spread, ensuring the effectiveness of dust cleaning. Finally, the air entering the cylinder a2 passes through the pipe c24 into each pipe d7, and is finally blown out in reverse by the pipe d7, thereby playing a role in offsetting part of the wind force. At the same time, the motor a23 is started, the motor a23 drives the pipe c24 to rotate, the pipe c24 drives each pipe d7 to make a circular motion, the pipe d7 drives the pipe b4 to make a circular motion, the pipe b4 drives the gear a8 to roll along the gear ring 6, so that the gear a8 drives the pipe b4 to rotate, the pipe b4 drives the fan plate 5 to rotate, generating a reverse wind force to offset part of the wind force, realizing the function of reducing the wind speed, and further reducing the flow rate (wind speed) of the airflow entering the cylinder a2.

[0045] When the dust is treated in the weather without wind or with small wind, the motor c22 can be started first, the motor c22 drives the screw rod to rotate, the screw rod drives the nut block to move away from the chute plate (the bottom end of the nut block and the sliding block is provided with a plurality of balls, which can reduce the friction between them and the chute plate), the nut block drives the cylinder b19 away from the cylinder a2 through the plate e21, so that the two are separated from each other, facilitating the subsequent angle adjustment of the cylinder a2; then the motor b20 is started, the gear c is driven to rotate by the motor b20, the gear c drives the gear b to rotate, the gear b drives the cylinder a2 to rotate through the rotating shaft, so that the cylinder a2 rotates 90 degrees, ensuring that the screen plate 3 is arranged downward, then the telescopic part a15 is used to push the pipe a10 to move towards the gear ring 6, the pipe a10 drives the ring b17 to rotate through the ring a16, the ring b17 drives the nozzle 11 to rotate (at the same time, the ring b17 will slide on the surface of the nozzle 11 for distance compensation), so that the nozzle 11 is arranged obliquely and points to the cylinder opening of the cylinder a2 (i.e. one end of the folded cloth 12), then the water in the water tank 28 is sprayed out through the atomizing nozzle 11 by using the submersible pump, the sprayed water mist is sprayed out through the cylinder opening and diffused into the air, realizing the dust cleaning function, at the same time, the telescopic part b27 is used to push the sliding rod 25 to move, and one end of the folded cloth 12 is driven to move by the sliding rod 25, so that it changes from folded to unfolded, so that the overall area increases, which can guide the falling dust to fall back into the cylinder a2, reducing the sediment on the ground, and improving the dust cleaning effect.

[0046] After the cleaning work is completed, the cylinder a2 and the cylinder b19 are combined again, so that the pipe a10 is driven to reciprocate by the telescopic part a15, then the reciprocating swing function of the nozzle 11 can be realized, at the same time, the mist particles sprayed out of the nozzle 11 are adjusted to the maximum, so that the flushing function of the inside of the cylinder a2 and the cylinder b19 is realized, and the sewage produced by flushing can flow into the recovery tank 1 through the screen plate 3 for recovery.

[0047] When the recovery tank 1 needs to be cleaned, the door plate 101 on the recovery tank 1 can be opened, so that the staff can enter the inside to clean.

[0048] The embodiments of the application are described in detail above in combination with the drawings, but the application is not limited thereto, various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the application.
