Description

Technical Field

[0001] The invention relates to the technical field of dust reduction, and in particular to a spray dust reduction device suitable for house infrastructure. Background Art

[0002] Housing infrastructure is generally referred to as construction engineering, which refers to the technical work such as survey, planning, design, construction, installation and maintenance for the construction, reconstruction or expansion of buildings and ancillary structures.

[0003] During the construction of housing projects, dust reduction spraying treatment is indispensable. The principle is to use the particles produced by spraying. Because of their extremely small size and basically zero surface tension, they can quickly absorb various sizes of dust particles in the air when sprayed into the air, forming effective dust control, which has a good effect on dust control and dust reduction in large open areas.

[0004] However, the spraying range and spraying angle of the dust suppression spray devices currently on the market are fixed. In addition, the water mist sprayed from the nozzles of the dust suppression spray devices is prone to cross-over, thereby forming larger water droplets, causing the larger water droplets to gather and drip near the water pipe, which not only wastes water resources, but also affects passing construction workers.

[0026] 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.

[0027] Embodiment 1: Figure 1-4 As shown, a spray dust reduction device suitable for house infrastructure proposed by the present invention comprises a mobile frame 1, a water storage tank 2 is arranged on the upper outer surface of the mobile frame 1, and a water pump is arranged inside the water storage tank 2, a water inlet pipe is arranged on one side of the water storage tank 2, and dust reduction water is injected into the water guide cavity through the water inlet pipe, a water spray plate 3 with a water guide cavity is arranged on the upper outer surface of the water storage tank 2 near both sides, and a guide pipe 4 is arranged on the lower outer surface of the water spray plate 3;

[0028] The dust suppression water in the water storage tank 2 enters the interior of the water spray pipe 601 through the guide pipe 4 under the action of the water pump. The guide pipe 4 is a hose that can adapt to the angle change of the water spray plate 3. One end of the guide pipe 4 penetrates into the interior of the water storage tank 2 and is connected to the output end of the water pump, and the guide pipe 4 is in communication with the water guide cavity.

[0029] An adjusting component 5 for adjusting the state of the water spray plate 3 is provided on the outer surface of the upper end of the water storage tank 2, and the adjusting component 5 corresponds to the water spray plate 3 one by one. The spray mechanism 6 includes a plurality of groups of water spray pipes 601 fixedly connected to the water spray plate 3, and a nozzle 602 is embedded and fixedly connected to the outer surface of one side of the water spray pipe 601. During the spraying process, it is unavoidable that part of the dust-reducing water directly drips on the surface of the water spray plate 3 and flows along the water spray plate 3 due to the spray force of the nozzle 602. Therefore, a collecting frame 603 is fixedly connected to the outer surface of one side of the water spray plate 3 near the bottom end. The collecting frame 603 collects the droplets flowing along the water spray plate 3 to prevent the droplets from dripping downward and affecting the passing construction personnel.

[0030] The water mist sprayed from the nozzle of the dust suppression spray device is prone to cross-over, and thus larger water droplets are formed, so that the larger water droplets gather and drip near the water spray pipe. Therefore, a fixed plate 604 is fixedly connected to the outer surface of the water spray plate 3 near both sides, and two groups of fixed plates 604 are respectively located at both ends of the water spray pipe 601. A number of groups of movable plates 605 are rotatably connected between the two groups of fixed plates 604 at equal distances, and a ventilation groove 606 is opened on the outer surface of one side of the movable plate 605. A dustproof net 607 is fixedly connected to the outer surface of the movable plate 605 at a position corresponding to the ventilation groove 606, and a ventilation pipe 608 connected to an external fan is fixedly connected to the side of the outer surface of the movable plate 605 away from the dustproof net 607. Under the action of the external fan, the airflow enters the interior of the ventilation groove 606 through the ventilation pipe 608.

[0031] The outer surfaces of both ends of the movable plate 605 are respectively fixedly connected with a rotating shaft 1 and a rotating shaft 2 609, and the rotating shaft 1 and the rotating shaft 2 609 are rotatably connected with the corresponding fixed plate 604. A motor 1 610 is arranged on the outer surface of one side of a group of fixed plates 604 near the top, and the output end of the motor 1 610 penetrates the fixed plate 604 and is fixedly connected with the corresponding rotating shaft 1. The motor 1 610 drives the corresponding rotating shaft 1 to drive the movable plate 605 to rotate. One end of the rotating shaft 2 609 penetrates the corresponding fixed plate 604 and is fixedly connected with a driving wheel 611. A conveyor belt 612 is transmission-connected between several groups of driving wheels 611, and several groups of movable plates 605 rotate in the same direction simultaneously under the transmission of the conveyor belt 612.

[0032] Embodiment 2: Figure 1 and Figure 7 As shown, the difference between this embodiment and embodiment 1 is that the adjustment component 5 includes a support plate 501 fixedly connected to the upper outer surface of the water tank 2 and located at both ends of the water spray plate 3, and the upper outer surface of the support plate 501 is provided with a movable groove 502, and an electric push rod 505 is arranged inside the movable groove 502, and one end of the electric push rod 505 is fixedly connected to the movable groove 502, and the other end is fixedly connected to the support plate 2 503, the electric push rod 1 505 pushes and pulls the support plate 2 503 up and down, so as to adjust the spraying height of the water spray plate 3, and the support plate 2 503 is movably connected to the movable groove 502.

[0033] The water spray plate 3 is rotatably connected to the corresponding two groups of support plates 503 through a rotating shaft. A motor 504 is provided on the outer surface of one side of one group of support plates 503, and the output end of the motor 504 passes through the support plate 503 and is fixedly connected to the corresponding rotating shaft. The rotating shaft is fixedly connected to the water spray plate 3. The motor 504 drives the water spray plate 3 to rotate, thereby adjusting the spraying angle of the water spray plate 3, so that the dust reduction water can fully contact and combine with the dust particles in the air under different wind directions.

[0034] Embodiment 3: Figure 2-6 As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that when the device is not working, some dust will inevitably remain on the surface of the nozzle 602 and the surface of the dustproof net 607. If they are not cleaned for a long time, the nozzle 602 and the dustproof net 607 will be blocked, and the spraying and dust reduction of the dust reduction water will be affected. Therefore, a spray mechanism 6 and a cleaning mechanism 7 for cleaning the spray mechanism 6 are provided on the side away from each other of the two groups of water spray plates 3. The cleaning mechanism 7 includes a limit plate 701, a limit groove 702, an electric push rod 703, a slider 704 and a cleaning roller 705;

[0035] The outer surface of one side of the water spray plate 3 is fixedly connected to the limiting plate 701 near the two sides, and the outer surface of one side of the limiting plate 701 is provided with a limiting groove 702, the limiting groove 702 extends to the interior of the collection frame 603, and the interior of the limiting groove 702 is provided with an electric push rod 2 703, one end of the electric push rod 2 703 is fixedly connected to the limiting groove 702, and the other end is fixedly connected to a slider 704, the electric push rod 2 703 pushes the slider 704 to slide along the limiting groove 702, and a cleaning roller 705 is provided between the two groups of corresponding sliders 704, and the cleaning roller 705 moves along the limiting groove 702 with the slider 704.

[0036] The two ends of the cleaning roller 705 are fixedly connected with a movable shaft 706, and the movable shaft 706 is rotatably connected to the slider 704, and one end of the movable shaft 706 passes through the slider 704 and is fixedly connected with a gear 707, and one side of the inner surface of the limiting groove 702 is fixedly connected with a rack 708, and the gear 707 is meshed with the rack 708, and the gear 707 moves relative to the movable shaft 706 and the rack 708, thereby driving the corresponding movable shaft 706 to rotate, and the outer surface of the cleaning roller 705 is provided with cleaning cotton 709, and the outer surface of the cleaning cotton 709 is in contact with the nozzle 602 and the dust-proof net 607. During the sliding process of the slider 704, the movable shaft 706 drives the cleaning roller 705 to rotate, and the cleaning roller 705 drives the cleaning cotton 709 on its surface to clean the nozzle 602 and the dust-proof net 607.

[0037] When the cleaning roller enters the collection frame 603, the dust-reducing water inside the collection frame 603 penetrates into the cleaning cotton 709. The cleaning roller 705 moves away from the collection frame 603 under the pull of the electric push rod 703 to clean the nozzle 602 and the dust-proof net 607 again, thereby reducing the waste of water resources and improving the cleaning intensity.

[0038] The working process and principle of the present invention are as follows:

[0039] Step 1: Before dust reduction, the motor is controlled to drive the water spray plate 3 to rotate. The guide pipe 4 is a hose that can adapt to the angle change of the water spray plate 3. At the same time, the height of the water spray plate 3 can be adjusted by controlling the electric push rod 505. Therefore, the spraying angle of the water spray plate 3 can be adjusted according to the dust distribution and wind direction to ensure that the dust reduction water can be evenly sprayed in the air.

[0040] Step 2: When dust is reduced, the water pump is turned on, and the dust reduction water in the water tank 2 enters the interior of the water spray pipe 601 through the guide pipe 4, and is sprayed into the air through the nozzle 602, and then combines with the dust particles in the air to form droplets that fall to the ground, effectively reducing dust on the house construction site;

[0041] Step 3: During the dust reduction process, the airflow enters the interior of the ventilation slot 606 through the ventilation pipe 608 under the action of the external fan, and is blown to the space between two adjacent groups of water spray pipes 601 through the dustproof net 607, so as to guide the spraying direction of the dust reduction water, so as to avoid the dust reduction effect being reduced due to the dust reduction water sprayed from the two adjacent groups of water spray pipes 601 combining directly to form large droplets at a low position, and the collection frame 603 collects the droplets flowing along the water spray plate 3, so as to avoid the droplets dripping downwards and affecting the passing construction personnel;

[0042] When spraying and dust reduction is performed, by controlling the operation of the motor 1 610, the movable plate 605 rotates under the drive of the motor 1 610 and the transmission of the conveyor belt 612, so that the blowing angle of the airflow can be adjusted according to the wind direction, further enhancing the dust reduction effect;

[0043] Step 4: Before cleaning, adjust the angle of the movable plate 605 to make it perpendicular to the water spray plate 3, and then control the electric push rod 2 703 to push the slider 704 to slide along the limit groove 702. Since the gear 707 is meshed with the rack 708, during the sliding process of the slider 704, the movable shaft 706 drives the cleaning roller 705 to rotate, and the cleaning roller 705 drives the cleaning cotton 709 on its surface to clean the nozzle 602 and the dustproof net 607, so as to ensure the smoothness and uniformity of the dust-reducing water spraying;

[0044] Step 5. When the cleaning roller 705 enters the interior of the collecting frame 603, the dust-reducing water inside the collecting frame 603 penetrates into the cleaning cotton 709. The cleaning roller 705 moves away from the collecting frame 603 under the pull of the electric push rod 2 703 to clean the nozzle 602 and the dust-proof net 607 again, thereby reducing the waste of water resources and improving the cleaning intensity.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
