Description

Technical Field

[0001] This utility model relates to the technical field of construction dust suppression equipment, specifically to a dust suppression spray device for building construction. Background Technology

[0002] Most dust suppression devices in construction projects use high-pressure pumps to pressurize water, which is then atomized into fine droplets through nozzles in a spray system and sprayed into the air. These fine droplets combine with dust particles in the air, increasing the weight of the dust particles and causing them to settle to the ground, thus achieving the purpose of dust suppression.

[0003] In the process of developing this application, the following problems were found with this technology: In existing building construction, industrial production and daily life, water storage tanks are widely used as important equipment for storing water resources. However, during long-term use, minerals and other substances contained in the water will gradually precipitate and adhere to the inner wall of the water tank, forming scale that affects water quality and makes it easy for subsequent spray devices to become blocked during use.

[0004] Therefore, a dust suppression spray device for construction engineering is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the problem that water storage tanks are widely used as important equipment for storing water resources in existing construction, industrial production, and daily life. However, during long-term use, minerals and other substances contained in the water will gradually precipitate and adhere to the inner wall of the water tank, forming scale that affects water quality and makes subsequent spraying devices prone to blockage during use. This utility model provides a dust suppression spraying device for construction engineering.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A dust suppression spray device for construction engineering includes a base and a water tank. A dust suppression spray body is rotatably connected to the upper surface of the water tank. The water tank is installed on the upper surface of the base. A cleaning mechanism for removing scale accumulated inside the water tank is installed inside. A filter assembly for circulating and cleaning the water flow inside the water tank is installed on the upper surface of the base. A water supply pipe is installed inside the water tank. A filter mechanism for filtering and drawing in water from the water supply pipe is installed on the outer wall of the water inlet end of the water supply pipe. A drain pipe is installed at the water inlet end of the dust suppression spray body.

[0008] Furthermore, the cleaning mechanism includes a U-shaped fixing plate, which is slidably connected to the top of the inner wall of the water storage tank. A slider is slidably connected inside the U-shaped fixing plate, and a second motor is installed at the bottom of the slider. A rotating rod is installed on the output shaft of the second motor to drive multiple sets of stirring rods to rotate.

[0009] Furthermore, the filtration assembly includes a water storage tank, a second filter screen, and a filter plate. The water storage tank is installed on the upper surface of the base. A second water supply pipe is installed at the outer end of the first drain pipe. The drain end of the second water supply pipe is installed at the top of the water storage tank. The drain pipe is installed at the outer end of the first water supply pipe. The inlet end of the second drain pipe is installed on the front of the water storage tank.

[0010] Furthermore, the second filter screen is installed at the top of the water storage tank, and the filter plate is installed inside the water storage tank.

[0011] Furthermore, the filtration mechanism includes a protective cover, which is installed on the outer wall of the water inlet end of the water supply pipe.

[0012] Furthermore, an acrylic panel is installed on the front of the water storage tank.

[0013] Furthermore, each of the four sets of stirring rods at the bottom end has a groove on the side away from the rotating rod, and an infrared rangefinder is installed inside the groove of each of the four sets of stirring rods at the bottom end. The infrared rangefinder is electrically connected to the control terminal of the cleaning mechanism.

[0014] Furthermore, the L-shaped fixing plate, the filtering mechanism, and the water supply pipe are located outside the rotation path of the multiple sets of stirring rods.

[0015] Furthermore, two sets of inclined plates are installed on the bottom of the inner wall of the water storage tank.

[0016] Furthermore, a guide plate is installed on the side of the water storage tank near the water reservoir.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model uses a second motor to drive a rotating rod and multiple sets of stirring rods to stir the water inside a water storage tank. This stirring process impacts the inner wall of the tank with the water flow. Then, by activating two sets of electric telescopic rods and a first motor, the stirring rods move back and forth and left and right within the tank. This allows the subsequent cleaning mechanism to flexibly adjust the position and angle of the turbulence-inducing body during startup. As a result, the multiple sets of stirring rods effectively impact and remove scale from the inner wall of the tank. Compared to traditional cleaning methods, this method is highly efficient, convenient, requires no chemical agents, and causes no damage to the tank, thus improving the practicality of the device.

[0019] 2. This utility model uses a water pump to extract the water used for cleaning scale accumulated inside the water storage tank. Then, by closing solenoid valve three and starting solenoid valve one, the water discharged from drain pipe one is guided back into the water storage tank. This allows the filter layer inside the water storage tank to filter the water used for cleaning scale. By activating the subsequent water pump, solenoid valve three, and closing solenoid valve one, the water accumulated in the water storage tank is guided to the spray dust suppression unit, enabling the water used for cleaning scale to be recycled. This reduces the water consumption during the use of the device and thus improves its environmental friendliness. Attached Figure Description

[0032] like Figures 1 to 7 As shown, a dust suppression spray device for construction engineering includes a base 1 and a water tank 10. A dust suppression spray body 2 is rotatably connected to the upper surface of the water tank 10. The water tank 10 is mounted on the upper surface of the base 1. A cleaning mechanism 8 for cleaning scale accumulated inside the water tank 10 is installed inside. A filter assembly 9 for circulating and cleaning the water flow inside the water tank 10 is installed on the upper surface of the base 1. A water supply pipe 4 is installed inside the water tank 10. A filter mechanism 7 for filtering and drawing water flow from the water supply pipe 4 is installed on the outer wall of the water inlet end of the water supply pipe 4. A drain pipe 3 is installed at the water inlet end of the dust suppression spray body 2. A water pump 17 is installed on the upper surface of the tank 10. The drain end of the water supply pipe 4 is installed inside the water inlet of the water pump 17. The inlet end of the drain pipe 3 is installed inside the drain end of the water pump 17. A solenoid valve 18 is installed on the outer wall of the drain pipe 3. The drain end of the solenoid valve 18 is installed inside the water inlet of the spray dust suppression body 2. An electrical control box 5 is installed on the side of the water storage tank 10 away from the filter assembly 9. Four sets of universal wheels 6 are installed at the lower end of the base 1. A water inlet pipe 15 is opened at the top of the water storage tank 10. Grooves are opened on the lower surfaces of the water storage tank 10 and the base 1. A water outlet pipe 13 is installed inside the grooves of the water storage tank 10 and the base 1.

[0033] Specifically, by activating the cleaning mechanism 8 and adjusting its position inside the water tank 10, the subsequent cleaning mechanism 8 can flexibly adjust the position and angle of the turbulence-disrupting body during activation. This allows the subsequent cleaning mechanism 8 to effectively impact and remove the scale adhering to the inner wall of the water tank 10 during activation. Compared with traditional cleaning methods, this method has advantages such as high efficiency, convenience, no need for chemical agents, and no damage to the tank, thus improving the practicality of the device.

[0034] like Figure 1 , Figure 4 and Figure 6As shown, the cleaning mechanism 8 includes a U-shaped fixing plate 801, which is slidably connected to the top of the inner wall of the water storage tank 10. A slider 807 is slidably connected inside the U-shaped fixing plate 801. A motor 808 is installed at the bottom of the slider 807. A rotating rod 810, which drives multiple sets of stirring rods 811, is installed on the output shaft of the motor 808. Two sets of electric telescopic rods 809 are installed on the inner wall of the back of the water storage tank 10. The output ends of the two sets of electric telescopic rods 809 are installed on the back of the U-shaped fixing plate 801. Grooves are provided on the inner walls of both the left and right sides of the U-shaped fixing plate 801. The two sets of grooves are rotatably connected to the screw 806. The lower surface of the U-shaped fixing plate 801 is equipped with an L-shaped fixing plate 802. The top of the inner wall of the L-shaped fixing plate 802 is equipped with a motor 805. The output shaft of the motor 805 is equipped with a bevel gear 804. The outer teeth of the bevel gear 804 are meshed with a bevel gear 803. The inner wall of the bevel gear 803 is installed on the outer surface of the screw 806. The slider 807 is threadedly connected to the outer end of the screw 806. The rotating rod 810 is installed on the output shaft of the motor 808. Multiple sets of stirring rods 811 are installed on the front, back, left and right sides of the rotating rod 810 respectively.

[0035] Specifically, by starting motor 2 808, the rotating rod 810 and multiple sets of stirring rods 811 are driven to stir inside the water storage tank 10. During the subsequent stirring process, the water flow inside the water storage tank 10 is agitated and impacts the inner wall of the water storage tank 10. Then, by starting two sets of electric telescopic rods 809 and motor 1 805, the multiple sets of stirring rods 811 are driven to move back and forth and left and right inside the water storage tank 10. This allows the subsequent cleaning mechanism 8 to flexibly adjust the position and angle of the turbulence-inducing body during the start-up process. As a result, the multiple sets of stirring rods 811 can effectively impact and remove the scale adhering to the inner wall of the water storage tank 10 during the rotation process. Compared with traditional cleaning methods, it has the advantages of high efficiency, convenience, no need for chemical agents and no damage to the tank body, thus improving the practicality of the device.

[0036] like Figure 1 , Figure 3 and Figure 7As shown, the filter assembly 9 includes a water storage tank 901, a second filter screen 904, and a filter plate 909. The water storage tank 901 is installed on the upper surface of the base 1. A second water supply pipe 903 is installed at the outer end of the first drain pipe 3. The drain end of the second water supply pipe 903 is installed at the top of the water storage tank 901. A second drain pipe 902 is installed at the outer end of the first water supply pipe 4. The inlet end of the second drain pipe 902 is installed on the front of the water storage tank 901. A first solenoid valve 906 is installed on the outer surface of the second water supply pipe 903. The second water supply pipe 903 is located at the lower end of the third solenoid valve 18. A second solenoid valve 907 is installed on the outer surface of the second drain pipe 902. A drain outlet is opened on the front of the water storage tank 901. The inlet end of the second drain pipe 902 is installed inside the drain outlet of the water storage tank 901. An inlet is opened at the top of the water storage tank 901. The drain end of the second water supply pipe 903 is installed inside the inlet of the water storage tank 901.

[0037] Specifically, by starting water pump 17, the water used for cleaning scale accumulated inside water tank 10 is pumped out of water tank 10. Then, by closing solenoid valve 3 18 and starting solenoid valve 1 906, the water discharged from drain pipe 3 is guided into water storage tank 901. This allows the filter layer inside water storage tank 901 to filter the water used for cleaning scale. By starting water pump 17, solenoid valve 3 18, and closing solenoid valve 1 906, the water accumulated in water storage tank 901 is guided to spray dust suppression body 2, allowing the water used for cleaning scale to be recycled. This reduces the water consumption during the use of the device and improves its environmental friendliness.

[0038] like Figure 3 and Figure 7 As shown, filter screen 904 is installed at the top of water storage tank 901, filter plate 909 is installed inside water storage tank 901, and the position of filter plate 909 is set at the lower end of the drain outlet of water supply pipe 903. The upper surface of filter plate 909 is sequentially equipped with coarse filter layer 908, fine filter layer 910, adsorption layer 911, biological treatment layer 912 and fine filter layer 913 from top to bottom. The position of coarse filter layer 908 is located at the lower end of the drain outlet of water supply pipe 903, and the position of filter screen 904 is located at the lower end of the spray end of spray dust suppression body 2. A fixing frame 905 is snapped into the top opening of water storage tank 901, and filter screen 904 is installed on the inner wall of fixing frame 905.

[0039] Specifically, the top opening of the water storage tank 901 is located directly below the spray end of the spray dust suppression body 2, allowing the water storage tank 901 to collect rainwater and water droplets dripping from the spray end of the spray dust suppression body 2. The water entering the water storage tank 901 is then filtered through a coarse filter layer 908, a fine filter layer 910, an adsorption layer 911, a biological treatment layer 912, and a fine filter layer 913, thereby minimizing the risk of blockage in the subsequent circulation and water delivery components caused by the water collected in the water storage tank 901 during use. A second filter screen 904 is installed at the top opening of the water storage tank 901, allowing the second filter screen 904 to perform initial filtration of the water entering the water storage tank 901, thereby minimizing the risk of larger particles entering the water storage tank 901 and causing some of the filter components 9 inside the water storage tank 901 to fail due to blockage.

[0040] like Figure 1 and Figure 2 As shown, the filtration mechanism 7 includes a protective cover 701, which is installed on the outer wall of the water inlet end of the water supply pipe 4. The protective cover 701 has grooves on the front, back, left, and right sides, and each of the four grooves of the protective cover 701 is equipped with a filter screen 702. Specifically, by setting the four filter screens 702 on the outer end of the water inlet end of the water supply pipe 4, the subsequent four filter screens 702 filter the water flow drawn into the protective cover 701 by the water supply pipe 4, thereby minimizing the risk of scale entering the interior of the water supply pipe 4 when the scale is cleaned in the circulating water tank 10, which could cause blockage of the subsequent water supply pipe 4 or the water pump 17.

[0041] like Figure 2 As shown, an acrylic plate 14 is installed on the front of the water tank 10, and a slot is provided on the front of the water tank 10. The acrylic plate 14 is installed inside the slot of the water tank 10. Specifically, because the acrylic plate 14 is made of transparent material, subsequent workers can see the thickness of the scale buildup inside the water tank 10 through the acrylic plate 14. This eliminates the need for subsequent workers to open the water tank 10 to check the scale thickness, thereby reducing the time and labor required for subsequent workers to check the scale thickness inside the water tank 10.

[0042] like Figure 1 and Figure 4As shown, each of the four sets of stirring rods 811 at the bottom has a groove on the side away from the rotating rod 810. An infrared rangefinder 12 is installed inside each of these grooves. The infrared rangefinder 12 is electrically connected to the control terminal of the cleaning mechanism 8, and also electrically connected to the control terminals of the two sets of electric telescopic rods 809 and motor 805. The output terminal of the infrared rangefinder 12 is electrically connected to the input terminal of the electrical control box 5. Specifically, by activating the infrared rangefinder 12, the distance between the stirring rod 811 and the inner wall of the water storage tank 10 is measured. The spacing is monitored so that when the data monitored by the infrared rangefinder 12 is lower than the preset value, the electrical control box 5 is triggered. Then, an electrical connection is made between the electrical control box 5 and the control terminals of the two sets of electric telescopic rods 809 and motor 805, so that the electrical control box 5 shuts down the two sets of electric telescopic rods 809 and motor 805 during the triggering process. This avoids the two sets of electric telescopic rods 809 and motor 805 from excessively adjusting and moving the positions of multiple sets of stirring rods 811, which could cause the subsequent stirring rods 811 to collide with the internal equipment of the water storage tank 10 or the inner wall of the water storage tank 10.

[0043] like Figure 1 and Figure 2 As shown, the L-shaped fixing plate 802, the filter mechanism 7, and the water supply pipe 4 are located outside the rotation path of the multiple sets of stirring rods 811. Specifically, by positioning the L-shaped fixing plate 802, the filter mechanism 7, and the water supply pipe 4 outside the rotation path of the multiple sets of stirring rods 811, collisions between the subsequent sets of stirring rods 811 and the L-shaped fixing plate 802, the filter mechanism 7, and the water supply pipe 4 are minimized during the rotation of the multiple sets of stirring rods 811, which disturb the water flow inside the water storage tank 10.

[0044] like Figure 1 As shown, two sets of inclined plates 11 are installed on the bottom of the inner wall of the water storage tank 10. The two sets of inclined plates 11 are positioned on both sides of the inlet of the water outlet pipe 13. Specifically, by installing the two sets of inclined plates 11 on the bottom of the inner wall of the water storage tank 10, the two sets of inclined plates 11 raise the height of the left and right sides of the inlet of the water outlet pipe 13. Furthermore, by setting the upper surface of the two sets of inclined plates 11 as an incline, the upper surface of the two sets of inclined plates 11 quickly guides the scale accumulated at the bottom of the water storage tank 10 to the inlet of the water outlet pipe 13, thereby shortening the time that the water storage tank 10 spends to discharge the scale accumulated inside.

[0045] like Figure 3As shown, a guide plate 16 is installed on the side of the water storage tank 10 near the water storage tank 901. A special-shaped groove is formed on the upper surface of the water storage tank 10. The guide plate 16 is located at the lower end of the drain outlet of the special-shaped groove of the water storage tank 10, and the drain end of the guide plate 16 is located at the upper end of the filter screen 904. Specifically, the special-shaped groove inside the water storage tank 10 is located at the lowest point of the upper end of the water storage tank 10, so that the special-shaped groove of the subsequent water storage tank 10 collects the water flow accumulated at the upper end of the water storage tank 10. Then, the guide plate 16 guides the water flow accumulated inside the special-shaped groove of the water storage tank 10 to the top opening of the water storage tank 901, thereby increasing the collection range of the subsequent water storage tank 901 in the process of collecting water flow, and shortening the time taken for the subsequent water storage tank 901 to be filled with water.

[0046] In summary: By starting motor 2 808, the rotating rod 810 and multiple sets of stirring rods 811 are driven to stir inside the water storage tank 10. This stirring process causes the water flow inside the water storage tank 10 to impact the inner wall of the water storage tank 10. Then, by starting two sets of electric telescopic rods 809 and motor 1 805, the multiple sets of stirring rods 811 are driven to move back and forth and left and right inside the water storage tank 10. This allows the subsequent cleaning mechanism 8 to flexibly adjust the position and angle of the turbulence-inducing body during startup, thereby enabling the multiple sets of stirring rods 811 to effectively impact and peel off the scale on the inner wall of the water storage tank 10 during rotation. Scale buildup on the inner wall of water tank 10; by starting water pump 17, the scale cleaning water accumulated inside water tank 10 is pumped out of water tank 10. Then, by closing solenoid valve 3 18 and starting solenoid valve 1 906, the water discharged from drain pipe 3 is guided to the interior of water storage tank 901, so that the filter layer inside water storage tank 901 filters the scale cleaning water discharged into water storage tank 901. By starting water pump 17, solenoid valve 3 18 and closing solenoid valve 1 906, the water accumulated in water storage tank 901 is guided to spray dust suppression body 2, so that the scale cleaning water can be recycled.

[0047] Meanwhile, the opening at the top of the water storage tank 901 is located directly below the spray end of the main dust suppression body 2, allowing the water storage tank 901 to collect rainwater and water droplets dripping from the spray end of the main dust suppression body 2. The water entering the water storage tank 901 is then filtered through a coarse filter layer 908, a fine filter layer 910, an adsorption layer 911, a biological treatment layer 912, and a fine filter layer 913, thus minimizing the risk of blockage in the subsequent circulation and water delivery components caused by the water collected inside the water storage tank 901 during use. The infrared rangefinder 12 monitors the distance between the stirring rod 811 and the inner wall of the water storage tank 10. When the data monitored by the infrared rangefinder 12 is lower than a preset value, the electrical control box 5 is triggered. The electrical control box 5 is then electrically connected to the control terminals of the two sets of electric telescopic rods 809 and motor 805, so that the electrical control box 5 shuts down the two sets of electric telescopic rods 809 and motor 805 during the triggering process.
