Description

Technical Field

[0001] The invention belongs to the technical field of spray dust reduction for building construction, and specifically relates to dust reduction equipment for building construction. Background Art

[0002] A large amount of dust will be generated during the construction process. This dust will not only pollute the surrounding environment, but also cause potential harm to human health, such as respiratory diseases. Therefore, taking effective dust prevention measures is very important to protect the health of construction workers and maintain environmental quality. The dust reduction equipment for construction is used for dust reduction at the construction site.

[0003] The dust suppression equipment commonly used in existing construction sites is the fog cannon. The working principle of the fog cannon is to use a high-pressure water pump to pressurize water to , and then spray it out through a high-pressure atomizing nozzle to form a water mist with a diameter similar to that of dust particles. Under the action of the fan, these fine water mists are blown to a farther place, combined with dust particles in the air and condensed into a mass, and finally settled to the ground, thereby achieving the effect of purifying the air;

[0004] However, in the prior art, when the fog cannon stops working, the water mist originally pumped to the nozzle by the high-pressure pump loses the support of the wind and falls back under the action of gravity. Since the fan is located at one end of the equipment, the water mist may be blocked by the fan blades during the falling process, thereby forming water droplets and flowing back to the direction of the fan. Over time, the backflow of water droplets may cause rust, corrosion or short circuit of key components such as the fan blades and motors, thereby affecting the normal operation and service life of the fog cannon.

[0005] Therefore, this solution proposes a dust reduction device for construction to solve the above problems. Summary of the invention

In the long run, the backflow of water droplets may cause key components such as fan blades and motors to rust, corrode or short-circuit, thereby affecting the normal operation and service life of the fog cannon.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figures 1-8 As shown, the present invention provides a dust reduction device for building construction, including a water tank 1, an adjustment component 4 and a spraying component 5. An adjustment component 4 is installed on the end face of the water tank 1. A spray cylinder 6 is arranged in the adjustment component 4. A fan 12 is arranged in the spray cylinder 6. The fan 12 is used to quickly and evenly transport the tiny water droplets atomized by the spraying component 5 to a longer distance and a larger range. A spraying component 5 is arranged between the adjustment component 4 and the water tank 1. The spraying component 5 is used to atomize the water in the water tank 1 and spray it outwards. An isolation component 7 is arranged in the inner cavity of the spray cylinder 6;

[0033] Among them, a control panel 2 is installed on the outer wall of the water tank 1. A control module is arranged in the control panel 2 and is connected to all the electrical devices in the device through wires and controls the operation of the electrical devices;

[0034] The isolation component 7 includes bolts 701. An arc-shaped plate 1 703 is rotatably installed on the bottom surfaces of the two bolts 701. An isolation cotton 702 is sleeved on the outer wall of the bolt 701;

[0035] The isolation cotton 702 is designed in an arc shape. The isolation cotton 702 is clamped between the arc-shaped plate 1 703 and the spray cylinder 6;

[0036] A plurality of bolts 701 are evenly threadedly connected to the outer wall of the spray cylinder 6;

[0037] A plurality of through holes 8 are evenly opened in the middle of the outer wall of the spray cylinder 6. The through holes 8 communicate with the inner cavity of the spray cylinder 6. The through holes 8 improve the water discharge efficiency when pressing the isolation cotton 702;

[0038] Among them, when the device is in normal use, the isolation cotton 702 increases the thickness of the spray tube 6, enhancing the isolation effect on the noise generated by the operation of the fan 12, making the device further conform to environmentally friendly construction;

[0039] When the device stops being used, the water mist that was originally pumped to the nozzle by the high-pressure pump loses the support of the wind force and will fall back under the action of gravity. During the fall, a large amount of water mist and water flow will be absorbed by the isolation cotton 702, further reducing the contact amount between the water and the fan 12;

[0040] When the first arc-shaped plate 703 is full of water, the motor 402 drives the rotating shaft 405, the fixing frame 406 and the spray tube 6 to rotate, adjusts the spray tube 6 to be inclined so that the fan 12 tilts upward, and then drives the isolation cotton 702 to press the first arc-shaped plate 703 through the rotating bolt 701, thereby achieving the effect of squeezing and discharging the water in the first arc-shaped plate 703 and improving the maintenance efficiency of the device;

[0041] Furthermore, an isolation net 13 is installed on the side of the spray tube 6 close to the fan 12. The isolation net 13 is used to isolate the fan 12 from the outside world, preventing the staff from accidentally touching the fan 12 when the fan 12 starts, causing personal injury problems;

[0042] In a further embodiment, referring to Figures 1-7 , the isolation cotton 702 is in contact with the inner cavity side wall of the spray tube 6. The isolation cotton 702 is used to isolate the noise generated when the fan 12 is in use.

[0043] In a further embodiment, referring to Figures 1-5 , the adjustment assembly 4 includes an installation frame 401 and a connecting frame 404. The installation frame 401 is installed on the end face of the water tank 1. The inner cavity bottom surface of the installation frame 401 is installed with a motor 403. A connecting frame 404 is connected to the power output shaft of the motor 403;

[0044] A motor 402 is installed on the outer wall of the connecting frame 404. The motor 402 penetrates through the outer wall of the connecting frame 404 and extends into the inner cavity of the connecting frame 404, and a rotating shaft 405 is installed. A fixing frame 406 is installed on the outer wall of the rotating shaft 405. The spray tube 6 is installed between the inner side walls on both sides of the fixing frame 406;

[0045] Among them, when the device is officially put into use, the motor 403 is started to drive the fixing frame 406 and the spray tube 6 to rotate in the horizontal direction, expanding the dust reduction range. The motor 402 is started to drive the rotating shaft 405, the fixing frame 406 and the spray tube 6 to swing in the vertical direction, further expanding the dust reduction range of the device.

[0046] In a further embodiment, referring to Figures 1-2, the spraying assembly 5 includes a water pump 501. The water pump 501 is installed on the top surface of the water tank 1. The water inlet of the water pump 501 is installed with a second water pipe 504. The second water pipe 504 penetrates through the top surface of the water tank 1 and extends into the inner cavity of the water tank 1. The water outlet end of the water pump 501 is installed with a first water pipe 502. A ring-shaped water pipe 503 is installed on the side of the first water pipe 502 away from the water pump 501. A plurality of atomizing nozzles are evenly arranged on the ring-shaped water pipe 503. The ring-shaped water pipe 503 is installed on the side wall of the spray cylinder 6;

[0047] Among them, when the device is in use, the fan 12 and the spraying assembly 5 are started simultaneously. The water pump 501 sequentially passes the water in the water tank 1 through the second water pipe 504, the water pump 501, the first water pipe 502 and the ring-shaped water pipe 503, and finally sprays out from the atomizing nozzles on the ring-shaped water pipe 503. Subsequently, under the action of the strong wind of the fan 12, the tiny water droplets atomized by the spraying assembly 5 are quickly and evenly transported to a longer distance and a larger range;

[0048] In a further embodiment, referring to Figures 1-4 , a water inlet pipe 3 is installed on the top surface of the water tank 1. The water inlet pipe 3 is communicated with the inner cavity of the water tank 1. A plurality of second arc-shaped plates 9 are evenly arranged on the bottom surface of the water inlet pipe 3. A moving disk 10 is slidably installed between the three second arc-shaped plates 9. A column 11 is installed on the end face of the moving disk 10;

[0049] The central axis of the moving disk 10 in the vertical direction coincides with the central axis of the moving disk 10 in the vertical direction;

[0050] Among them, before the device is put into use, the water tank 1 is first filled with water. The injection process is as follows: Connect the water pipe to the water inlet pipe 3, and as the water is injected into the water tank 1, the water level in the water tank 1 will rise. The rising water level will drive the moving disk 10 and the column 11 to rise synchronously. When the column 11 extends out of the water inlet pipe 3, it means that the water in the water tank 1 is about to be filled, giving a signal to the staff to end the water injection in advance. And when the water tank 1 is filled with water, the moving disk 10 will be in contact with the bottom surface of the water inlet pipe 3, closing the inner cavity of the water tank 1 and the outside world, and preventing foreign objects from falling into the water tank 1 through the water inlet pipe 3 when not in use.

[0051] The working principle of the present invention is as follows: When the device is in use, first power on all the equipment in the device;

[0052] Before the device is put into use, first fill the water tank 1. The injection process is as follows: Connect the water pipe to the water inlet pipe 3, and as water is injected into the water tank 1, the water level in the water tank 1 will rise. The rising water level will drive the moving disk 10 and the column 11 to rise synchronously. When the column 11 extends out of the water inlet pipe 3, it means that the water in the water tank 1 is about to be full, giving a signal to the staff to end the water injection in advance. And when the water tank 1 is full of water, the moving disk 10 will contact the bottom surface of the water inlet pipe 3, sealing the inner cavity of the water tank 1 from the outside world to prevent foreign objects from falling into the water tank 1 through the water inlet pipe 3 when not in use.

[0053] When the device is officially put into use, start the second motor 403 to drive the fixed frame 406 and the spray barrel 6 to rotate horizontally, expanding the dust suppression range. Start the first motor 402 to drive the rotating shaft 405, the fixed frame 406 and the spray barrel 6 to swing vertically, further expanding the dust suppression range of the device.

[0054] When the device is in use, the fan 12 and the spray component 5 are started simultaneously. The water pump 501 pumps the water in the water tank 1 sequentially through the second water pipe 504, the water pump 501, the first water pipe 502 and the annular water pipe 503, and finally sprays out from the atomizing nozzles on the annular water pipe 503. Subsequently, under the strong wind force of the fan 12, the tiny water droplets atomized by the spray component 5 are quickly and evenly transported to a longer distance and a larger range.

[0055] When the device is in normal use, the isolation cotton 702 increases the thickness of the spray barrel 6, enhancing the isolation effect on the noise generated by the operation of the fan 12, making the device further meet the requirements of environmental protection construction.

[0056] When the device stops being used, the water mist that was originally pumped to the nozzle by high pressure loses the support of the wind force and will fall back under the action of gravity. When falling back, a large amount of water mist and water flow will be absorbed by the isolation cotton 702, further reducing the contact amount between water and the fan 12, solving the problem in the prior art that when the fog cannon machine stops working, the water mist that was originally pumped to the nozzle by high pressure loses the support of the wind force and will fall back under the action of gravity. Over time, the reverse flow of water droplets may cause key components such as the fan blades and the motor to rust, corrode or short-circuit, thereby affecting the normal operation and service life of the fog cannon machine.

[0057] When the first arc-shaped plate 703 is full of water, use the first motor 402 to drive the rotating shaft 405, the fixed frame 406 and the spray barrel 6 to rotate, adjust the spray barrel 6 to be inclined so that the fan 12 tilts upward, and then drive the isolation cotton 702 to press the first arc-shaped plate 703 by rotating the bolt 701, thereby achieving the effect of squeezing out the water in the first arc-shaped plate 703 and improving the maintenance efficiency of the device.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
