Description

Technical Field

[0001] The invention relates to the technical field of dust suppression devices, and in particular to a dust suppression system for green building construction. Background Art

[0002] Green buildings, throughout their life cycle, save resources, protect the environment, reduce pollution, and provide people with healthy, applicable, and efficient use of space. During the construction of green buildings, some soil and sand and gravel are needed to plant green plants. Dust pollution is easily caused during the construction process, affecting the health of surrounding residents and construction workers. Dust reduction treatment is required through a construction dust reduction system. The general dust reduction method is to use water sprinkling. Common water sprinkling dust reduction methods include artificial watering and water sprinkling by sprinkler trucks.

[0003] The problem with the existing water sprinkling method for dust reduction is that at the construction site, construction is carried out at multiple points at the same time, resulting in different directions of dust generation. Whether it is manual sprinkling or equipment sprinkling, only continuous sprinkling can reduce dust. The usually adopted method is covering sprinkling to achieve the overall dust reduction effect, which easily leads to a waste of water resources. In addition, it is impossible to better judge the time when sprinkling is needed, and it requires human subjective consciousness to decide whether sprinkling is needed for dust reduction. This treatment method will also affect the efficiency of dust reduction and cause some dust to be integrated into the air and pollute the air. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a dust reduction system for green building construction to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure, and performs multi-stage water sprinkling and dust reduction through a spray rack and a spray plate. Conventional surround dust reduction is performed through the spray rack to reduce dust in the surrounding air. The air in the opening direction is sucked in through the layer filters in the two sets of connecting pipes alternately used in the water pumping box. When a lot of dust accumulates, it will cause the connecting pipe to be blocked, and the gas cannot enter the water pumping box. The water in the base is pumped out through the negative pressure effect in the water pumping box and transported to the spray plate. Additional efficient spraying and dust reduction are performed on areas with more dust in the air, thereby improving the dust reduction effect and avoiding the waste of water resources in other directions where there is not much dust.

[0010] Furthermore, two outlets are provided at the bottom of the water pumping box corresponding to the positions of the suction pipe and the delivery pipe, and a turntable is rotatably installed on the inner wall of the bottom of the water pumping box through a bearing, and the turntable covers the top of the suction pipe and the delivery pipe. Through holes are provided on the surface of the turntable, and the through holes correspond alternately to the outlets of the suction pipe and the delivery pipe.

[0014] Furthermore, the cleaning assembly also includes a filter plate, the filter plate is fixed inside the reflux box, and the central tube slides out of the filter plate, a reflux pipe is provided on one side of the bottom of the reflux box, and the other end of the reflux pipe penetrates into the water cavity of the base.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention drives the rotation of the disc by meshing the first gear ring with the four second gear rings, so that the four groups of water pumping boxes rotate and the positions of the two connecting pipes are exchanged. At this time, the inside of the connecting pipe is blocked by the baffle plate, and the water cavity in the base sends water to the central pipe through the water pump, and is sprayed on the inside of the connecting pipe through the third nozzle to flush the multi-layer filter screen. The flushed sewage flows into the return box, is filtered by the filter plate, and then returns to the water cavity in the bottom box from the return pipe. The baffle of the connecting pipe is opened, and the flushed connecting pipe is dried. The cleaning process is that the connecting pipes facing the four third nozzles are flushed after they are closed by the baffle plate. The two groups of connecting pipes can be used alternately, which has a certain dust detection effect.

[0017] 2. When the connecting pipe of the present invention is in use, the electric plug plate plugged into the top of the storage box facing outwards will store the baffle inside the storage box. At this time, the connecting pipe is unobstructed, and the connecting pipe facing the cleaning component side is pushed by the electric plug plate, and the baffle blocks the connecting pipe to prevent the cleaned sewage from flowing into the water pumping box. Only when the outer connecting pipe is unobstructed can air enter the water pumping box through the connecting pipe, and then the gas is sent out from the connecting pipe through the movement of the piston of the circular plate to maintain the gas balance in the water pumping box. When the connecting pipe facing outwards is blocked, the first electric push rod drives the connecting ring to descend, and the electric plug plate drives the baffle to pass through the storage box. The baffles on both sides of the water pumping box block the connecting pipe at the same time. At this time, with the movement of the circular plate, negative pressure will be generated inside the water pumping box, thereby pumping the water in the water cavity of the base into the water pumping box.

[0018] 3. The present invention sends water into the water pumping box. At this time, the second electric push rod drives the circular plate to descend to cooperate with the inhalation of air, and then the circular plate is moved upward by the second electric push rod. The fan reverses at this time to send out the air. This state can only be performed when the inside of the connecting pipe is unobstructed. When the multi-layer filter is blocked, as the circular plate moves, there is no gas flow and a negative pressure environment will be generated, thereby pumping the water in the base into the water pumping box through the pumping pipe. When the water level sensor first detects that water has entered the water pumping box, the two connecting pipes are sealed, and the circular plate is continuously moved upward to accumulate more water in the water pumping box. Then the drive motor drives the turntable to rotate, and the through hole of the turntable is matched with one side of the delivery pipe. At the same time, the second electric push rod drives the circular plate to descend, and the water in the water pumping box is sent to the spray plate through the second delivery pipe, and secondary spraying and dust reduction are performed in the direction with more dust.

[0019] 4. The spray plate of the present invention can adjust the direction of water spraying through the mounting seat at the bottom. The mounting seat is installed on the shaft ring and then connected to the first delivery pipe through the connecting plate. Because the rotation direction of the water pumping box rotates around the center of the disk, it will not collide with the spray plate. In addition, there is a certain distance between each group of water pumping boxes, which can avoid collision of the connecting pipe position, thereby keeping the spray plate facing outward at all times.

[0020] 5. The present invention can achieve the docking and separation of the air inlet pipe and the connecting pipe by moving the mounting frame through the third electric drive, thereby facilitating the rotation of the water pump box to switch the connecting pipe for use and avoiding affecting the rotation of the connecting pipe.

[0021] 6. Compared with the prior art, the present invention uses a spray rack and a spray plate to perform multi-stage water sprinkling to reduce dust, uses a spray rack to perform conventional surround dust reduction, reduces dust in the surrounding air, and uses two sets of alternately used connecting pipes of a water pumping box to inhale air in the opening direction. When dust accumulates too much, it will cause the connecting pipe to be blocked, and the gas cannot enter the water pumping box. The water in the base is pumped out through the negative pressure effect in the water pumping box and transported to the spray plate, so that additional efficient spraying and dust reduction are performed on areas with more dust in the air, thereby improving the dust reduction effect and avoiding the waste of water resources in other directions where there is not much dust.

The suction pipe 210 passes through the disc 62 and communicates with the water cavity inside the base 1, and two fixing columns 29 are fixed at the bottom of the water pumping box 2, and the fixing columns 29 are fixed on the disc 62. When using the device, the device is set at the construction site, and the water inlet pipe 11 of the base 1 is connected to the water source to keep There is sufficient water in the water cavity inside the bottom box, and simple surrounding water sprinkling is carried out through the spray rack 4 and the first nozzle 42 to carry out primary dust reduction on the surrounding environment. The amount of water sprayed for dust reduction is relatively small, and the air in each direction is detected separately by relying on the outer connecting pipes 21 of the water pumping box 2 arranged in four directions. When there is a lot of dust in the air, water is accumulated inside the water pumping box 2 and transported to the spray plate 5. The nozzle of the spray plate 5 sprays it in the direction of more dust, and cooperates with the spray rack 4 to focus on water sprinkling and dust reduction in areas with more dust. It is more targeted and avoids waste of water resources.

[0033] In this embodiment, a fan 32 is rotatably mounted inside the air inlet duct 3 through a bearing frame, and a mounting frame 31 is fixed to the outer surface of the air inlet duct 3. A third electric push rod 33 is fixed to the outer edge of the base 1 at a position corresponding to the bottom of the mounting frame 31, and the extended end of the third electric push rod 33 is fixedly connected to the mounting frame 31. By moving the mounting frame 31 driven by the third electric drive, the air inlet duct 3 and the connecting pipe 21 can be docked and separated, thereby facilitating the rotation of the water pump box 2 to switch the connecting pipe 21 for use, and avoiding affecting the rotation of the connecting pipe 21.

[0034] In this embodiment, a first delivery pipe 41 is fixed to the top of the central pipe 73, and the first delivery pipe 41 is connected to the spray rack 4. A collar 55 is rotatably mounted on the top of the water pumping box 2. A connecting plate 56 is fixed to the side of the collar 55 facing the first delivery pipe 41. Four groups of connecting plates 56 are fixedly sleeved on the surface of the first delivery pipe 41. A mounting seat 54 is fixed to the bottom of the spray plate 5 on the other side of the collar 55. The bottom of the spray plate 5 is rotatably mounted on the mounting seat 54 through a rotating shaft. The bottom of the water pumping box 2 is located on one side of the suction pipe 210. A delivery pipe 53 is provided, and the delivery pipe 53 is connected to a second delivery pipe 51, the other end of the second delivery pipe 51 is connected to the spray plate 5, and the second delivery pipe 51 is a hose, and two outlets are provided at the bottom of the pumping box 2 corresponding to the positions of the suction pipe 210 and the delivery pipe 53, and a turntable 212 is rotatably installed on the inner wall of the bottom of the pumping box 2 through a bearing, and the turntable 212 covers the top of the suction pipe 210 and the delivery pipe 53, and a through hole 213 is provided on the surface of the turntable 212, and the through hole 213 is alternately connected to the suction pipe 210 and the delivery pipe 53.

The mounting seat 54 is installed on the shaft ring 55 and then connected to the first delivery pipe 41 through the connecting plate 56. Because the rotation direction of the pumping box 2 is circular, The disk 62 rotates around the center of the circle without colliding with the spray plate 5, and there is a certain distance between each group of water pumping boxes 2, which can avoid collision at the position of the connecting pipe 21, so that the spray plate 5 can be kept facing outward at all times. The spray rack 4 is installed on the top of the central tube 73 through the first delivery pipe 41, and is transported to the first delivery pipe 41 by the water pump in the central tube 73, and then sent to the first nozzle 42 of the spray rack 4 through the first delivery pipe 41 for spraying.

[0035] In this embodiment, a second electric push rod 27 is fixed on the outer wall of the top of the water pumping box 2, and the extended end of the second electric push rod 27 is fixedly connected to the circular plate 211. A water level sensor 214 is fixedly installed on the inner wall of the top of the water pumping box 2, and the circular plate 211 slides along the water level sensor 214. After the outward connecting pipe 21 is connected to the air inlet pipe 3, the fan 32 in the air inlet pipe 3 is turned on to suck air into the connecting pipe 21 and then sent into the water pumping box 2. At this time, the second electric push rod 27 drives the circular plate 211 to descend to cooperate with the air intake, and then the circular plate 211 is moved upward by the second electric push rod 27. The fan 32 reverses at this time to send the air out. This state is only in the unobstructed state inside the connecting pipe 21. When the multi-layer filter 26 is blocked, as the circular plate 211 moves, a negative pressure environment will be generated without the flow of gas, so that the water in the base 1 is pumped into the water pumping box 2 through the pumping pipe. When the water level sensor 214 first detects that water has entered the water pumping box 2, the two connecting pipes 21 are sealed, and the circular plate 211 is continuously moved upward. More water is accumulated in the water pumping box 2, and then the turntable 212 is driven by the driving motor 28 to rotate, and the through hole 213 of the turntable 212 is aligned with one side of the delivery pipe 53. At the same time, the second electric push rod 27 drives the circular plate 211 to descend, and the water in the water pumping box 2 is sent to the spray plate 5 through the second delivery pipe 51, and the secondary spray dust reduction is performed in the direction where there is more dust.

[0036] In this embodiment, a multi-layer filter screen 26 is arranged inside the connecting pipe 21, and a storage box 22 is fixedly arranged between the multi-layer filter screen 26 and the inlet of the water pumping box 2, and a baffle 215 is slidably accommodated inside the storage box 22, and the baffle 215 can block the connecting pipe 21, and an electric plug plate 23 is slidably inserted at the top of the storage box 22, and the bottom of the electric plug plate 23 is fixedly connected to the baffle 215, a connecting ring 24 is slidably sleeved on the outer surface of the water pumping box 2, and the top of the electric plug plate 23 is fixedly connected to the connecting ring 24, first electric push rods 25 are fixedly arranged on the outer walls of both sides of the water pumping box 2, and the extended ends of the first electric push rods 25 are fixedly connected to the connecting rings 24, the principle of the electric plug plate 23 is the same as that of the electric push rod, and a retractable connecting rod is arranged inside it for individually controlling the movement of the baffle 215, and when the connecting pipe 21 is in use, the top of the storage box 22 facing outward is inserted The connected electric plug plate 23 stores the baffle 215 inside the storage box 22. At this time, the connecting pipe 21 is unobstructed, and the connecting pipe 21 facing the cleaning component 7 is pushed by the electric plug plate 23, and the baffle 215 blocks the connecting pipe 21 to prevent the cleaned sewage from flowing into the water pumping box 2. Only when the outer connecting pipe 21 is unobstructed, can air enter the water pumping box 2 through the connecting pipe 21, and then the gas is sent out from the connecting pipe 21 through the piston movement of the circular plate 211 to maintain the gas balance in the water pumping box 2. When the connecting pipe 21 facing the cleaning component 7 is blocked, the first electric push rod 25 drives the connecting ring 24 to descend, and the electric plug plate 23 drives the baffle 215 to pass through the storage box 22. The baffles 215 on both sides of the water pumping box 2 block the connecting pipe 21 at the same time. At this time, with the movement of the circular plate 211, negative pressure will be generated inside the water pumping box 2, thereby pumping the water in the water cavity of the base 1 into the water pumping box 2.

[0037] In this embodiment, the driving assembly 6 includes a first gear ring 61, the first gear ring 61 is rotatably sleeved on the outer surface of the bottom of the reflux box 71, the outer ring of the disc 62 is fixedly sleeved with a second gear ring 63, and the first gear ring 61 is meshed and connected with the second gear ring 63, and a motor for driving the first gear ring 61 is arranged inside the base 1, and the cleaning assembly 7 also includes a filter plate 72, the filter plate 72 is fixed inside the reflux box 71, and the center tube 73 slides out of the filter plate 72, a reflux pipe 75 is arranged on one side of the bottom of the reflux box 71, and the other end of the reflux pipe 75 penetrates into the water cavity of the base 1, and the blocked multi-layer filter screen 26 drives the first gear ring 61 to rotate through the motor inside the base 1, and the first gear ring 61 and the four second gear rings 6 The engagement drives the disc 62 to rotate, so that the four groups of pumping boxes 2 rotate and the positions of the two connecting pipes 21 are exchanged. At this time, the inside of the connecting pipe 21 is blocked by the baffle 215, and the water cavity in the base 1 sends water to the central pipe 73 through the water pump, and sprays it on the inside of the connecting pipe 21 through the third nozzle 74 to flush the multi-layer filter 26. The sewage after flushing flows into the return box 71, is filtered by the filter plate 72, and then returns to the water cavity in the bottom box from the return pipe 75, and the baffle 215 of the connecting pipe 21 is opened to dry the flushed connecting pipe 21. The cleaning process is that the connecting pipes 21 facing the four third nozzles 74 are all closed by the baffle 215 and then flushed. This process is uniformly controlled by the first electric push rod 25 and the connecting ring 24.

[0038] When using the device, it is set up at the construction site, and the water inlet pipe 11 of the base 1 is connected to the water source to keep the water source in the water cavity inside the bottom box sufficient. A simple surrounding watering is performed through the spray rack 4 and the first nozzle 42 to perform primary dust reduction on the surrounding environment. The amount of watering for dust reduction is small, and the air in each direction is detected separately by relying on the outer connecting pipes 21 of the water pumping box 2 arranged in four directions. When there is a lot of dust in the air, after the outward connecting pipe 21 is connected to the air inlet pipe 3, the fan 32 in the air inlet pipe 3 is turned on to suck air into the connecting pipe 21 and then send it into the water pumping box 2. At this time, the second electric push rod 27 drives the circular plate 211 to descend to cooperate with the inhalation of air, and then the circular plate 211 is moved upward by the second electric push rod 27. The fan 32 At this time, it is reversed to send out the air. This state can only be performed when the inside of the connecting pipe 21 is unobstructed. When the multi-layer filter 26 is blocked, as the circular plate 211 moves, there is no gas flow and a negative pressure environment will be generated, thereby pumping the water in the base 1 into the water pumping box 2 through the pumping pipe. When the water level sensor 214 first detects that water has entered the water pumping box 2, the two connecting pipes 21 are sealed, and the circular plate 211 is continuously moved upward. More water is accumulated in the water pumping box 2, and then the turntable 212 is driven by the driving motor 28 to rotate, and the through hole 213 of the turntable 212 is aligned with one side of the delivery pipe 53. At the same time, the second electric push rod 27 drives the circular plate 211 to descend, and the water in the water pumping box 2 is sent to the spray plate 5 through the second delivery pipe 51. Secondary spraying dust reduction is performed in the direction with more dust in front. During the use stage of the connecting pipe 21 facing in the direction of use, the electric plug board 23 plugged into the top of the storage box 22 facing outward stores the baffle 215 inside the storage box 22. At this time, the connecting pipe 21 is unobstructed, and the connecting pipe 21 facing the cleaning component 7 is pushed by the electric plug board 23, and the baffle 215 blocks the connecting pipe 21 to prevent the cleaned sewage from flowing into the water pumping box 2. Only when the outer connecting pipe 21 is unobstructed, can air enter the water pumping box 2 through the connecting pipe 21, and then the piston of the circular plate 211 moves to send the gas out of the connecting pipe 21 to maintain the gas balance in the water pumping box 2. When the connecting pipe 21 facing in the direction of blockage occurs, the first electric push rod 25 drives the connecting ring 24 to descend, and the electric The movable plug plate 23 drives the baffle plate 215 to pass through the storage box 22, and the baffle plates 215 on both sides of the water pumping box 2 simultaneously block the connecting pipe 21. At this time, with the movement of the circular plate 211, negative pressure will be generated inside the water pumping box 2, so that the water in the water cavity of the base 1 is pumped into the water pumping box 2, and the water is sprayed in the direction of more dust by the nozzle of the spray plate 5, and cooperates with the spray rack 4 to focus on the dusty area to spray water and reduce dust, which is more targeted and avoids the waste of water resources. The blocked multi-layer filter 26 drives the first gear ring 61 to rotate through the motor inside the base 1. The first gear ring 61 is engaged with the four second gear rings 63 to drive the rotation of the disc 62, so that the four groups of water pumping boxes 2 rotate and the positions of the two connecting pipes 21 are exchanged. At this time, the inside of the connecting pipe 21 is blocked by the baffle plate 215.The water cavity in the base 1 delivers water to the central pipe 73 through a water pump, and sprays water inside the connecting pipe 21 through the third nozzle 74 to flush the multi-layer filter 26. The flushed sewage flows into the return box 71, is filtered by the filter plate 72, and then returns to the water cavity in the bottom box from the return pipe 75. The baffle 215 of the connecting pipe 21 is opened to dry the flushed connecting pipe 21. The cleaning process is to flush the connecting pipes 21 facing the four third nozzles 74 after they are closed by the baffle 215. This process is uniformly controlled by the first electric push rod 25 and the connecting ring 24. The two groups of connecting pipes 21 can be used alternately, which has a certain dust detection effect.
