Description

Technical Field

[0001] This invention relates to the field of dust suppression technology, specifically to a water spraying device for heatstroke prevention and dust removal in building construction. Background Technology

[0002] With the rapid pace of urban modernization, numerous construction sites have inevitably emerged in cities. These construction activities have a significant negative impact on the surrounding environment, with dust pollution being the most prominent issue. Construction sites generate substantial amounts of dust during the construction process. If left unchecked, this dust will fill the surrounding air with excessive amounts of pollutants. Furthermore, this dust contains numerous substances harmful to human health, impacting the health of residents in the surrounding urban areas. This not only affects residents' physical health but also negatively impacts the city's image. Therefore, dust suppression equipment is needed to effectively control dust at construction sites.

[0003] Chinese patent application CN116099310A discloses a dust suppression device for earthwork at a construction site, including an exhaust duct. A bracket is fixedly connected to the outer wall of the exhaust duct, a fixed frame is fixedly connected to the left side of the inner wall of the exhaust duct, a motor is fixedly connected to the inner wall of the fixed frame, a connecting pipe is fixedly connected to the right side of the exhaust duct, a first water inlet pipe is fixedly connected to the lower side of the connecting pipe, the interior of the first water inlet pipe is connected to the interior of the connecting pipe, a plurality of installation ports are provided on the connecting pipe, a drainage mechanism is provided inside the installation ports, and an exhaust mechanism is provided at the output end of the motor.

[0004] In the actual use of the dust suppression device for earthwork at the aforementioned construction site, when the fan draws in outside air, it also sucks in suspended dust in the air. The dust-laden airflow carried by the fan will come into contact with and mix with the water mist sprayed by the device before the earthwork dust to be treated. During this process, some of the water mist will combine with and settle with the dust sucked in by the fan in advance, resulting in a significant consumption of the effective water mist volume participating in the subsequent main dust suppression stage. This reduces the water mist capacity that can act on the earthwork dust at the construction site, which in turn easily leads to a decrease in the overall water mist dust suppression effect and significantly reduces the dust suppression efficiency and performance of the device. Summary of the Invention

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A water spraying device for heatstroke prevention and dust suppression in construction includes a movable base, a water tank, a hollow cylinder, a ventilation cylinder, a support frame, and a material dropping component. The water tank is installed on the movable base, and the hollow cylinder is installed on the water tank via the support frame. The support frame has an annular cavity, and the outer wall of the hollow cylinder is fixed to the cavity wall of the annular cavity. The ventilation cylinder is fixedly connected to one side of the hollow cylinder, and the material dropping component is fixedly connected to the bottom end of the ventilation cylinder. A material dropping port is provided at the bottom of the ventilation cylinder. The hollow cylinder is equipped with a dust removal component, which can perform dust suppression pretreatment on the gas entering the ventilation cylinder. The water source for dust suppression pretreatment falls into the water tank through the discharge port for reuse.

[0006] Preferably, the dust removal assembly includes a first annular pipe installed on a hollow cylinder, a plurality of first spray heads installed on the outer surface of the first annular pipe, and the plurality of first spray heads are arranged in a ring on the outer surface of the first annular pipe. A water pumping pipe is fixedly connected to the bottom of the first annular pipe, and the end of the water pumping pipe away from the first annular pipe extends into the interior of a water tank. An induced draft fan is installed inside the hollow cylinder.

[0007] Preferably, a second annular pipe is installed on the inner wall of the ventilation cylinder, and a plurality of second spray heads are installed on the inner annular surface of the second annular pipe. The plurality of second spray heads are arranged in a ring on the outer surface of the first annular pipe. A connecting water pipe is fixedly connected to the outer wall of the second annular pipe, and the end of the connecting water pipe away from the second annular pipe passes through the ventilation cylinder and is fixedly connected to the outer wall of the water pumping pipe.

[0008] Preferably, the water tank is equipped with a filtration mechanism, which includes a filtration component and an anti-clogging component. The filtration component includes an inner cylinder fixedly connected to the bottom of the water pump pipe, with the bottom end of the inner cylinder penetrating the top of the water tank and extending into the interior of the water tank. The interior of the inner cylinder is connected to the interior of the water pump pipe. A sleeve is provided inside the inner cylinder, and the sleeve is coaxially arranged with the inner cylinder. The inner wall of the inner cylinder fits against the outer wall of the sleeve, and the sleeve is slidably connected inside the inner cylinder. Two openings are opened on the outer surface of the sleeve, and an arc-shaped filter screen is fixed to the inner wall of each of the two openings.

[0009] Preferably, the anti-clogging component includes a first side plate fixed to the outer surface of the inner cylinder, a second side plate fixed to the outer wall of the sleeve, a lifting block fixed to the top of the second side plate, two limiting ports adapted to the lifting blocks being opened at the top of the water tank, and the lifting blocks being slidably connected inside the corresponding limiting ports, and the top of the lifting block extending out of the limiting port and fixed to the bottom of the first side plate.

[0010] Preferably, a return spring is fixed between the bottom of the first side plate and the top of the water tank to support the first side plate and drive it to return to its original position.

[0011] Preferably, a side block is fixed on one side of the first side plate, and a sliding opening adapted to the side block is provided on the support frame. The side block is slidably connected inside the corresponding sliding opening. A drive disk is provided on one side of the side block, and a drive block is fixed on the surface of the drive disk.

[0012] Preferably, the drive block has an arc-shaped surface, and the edges of the side blocks also have arc-shaped surfaces.

[0013] Preferably, the first side plate is provided with a limiting hole that is adapted to the inner cylinder, and the outer wall of the inner cylinder is fixed on the inner wall of the corresponding limiting hole.

[0014] Preferably, a drive source is fixed on one side of the drive disk, and the output end of the drive source is fixed in the middle of the drive disk.

[0015] The beneficial effects of this invention are as follows: 1. By adopting a dual-ring spray system, dust capture and settling efficiency is significantly improved, ensuring that the air purification effect meets the standards. On the one hand, multiple first spray heads are evenly distributed on the first annular pipe on the outside of the hollow cylinder. The annular arrangement of the spray heads can form an all-round, dead-angle-free spray coverage area. Combined with the forced ventilation of the exhaust fan inside the hollow cylinder, the surrounding air to be purified can be directionally drawn into the hollow cylinder and ventilation cylinder, so that the airflow and spray can fully contact each other, efficiently capturing suspended dust in the air and realizing the main dust suppression operation. On the other hand, the second annular pipe on the inner wall of the ventilation cylinder is also equipped with multiple annularly arranged second spray heads. Water is drawn from the water pipe through the connecting water pipe and pre-treated before the air enters the main dust suppression area, pre-settling some large dust particles, reducing the load on the main dust suppression process, and further improving the overall dust suppression effect.

[0016] 2. During the dust suppression process, the water mist sprayed from the first and second spray heads captures the dust, and the resulting wastewater and dirt slides down the inner wall of the ventilation cylinder, enters the discharge port at the bottom of the ventilation cylinder, and then flows back into the water tank through the discharge port, thus completing the reuse of water resources and avoiding the waste of water resources caused by the direct discharge of dust suppression wastewater. At the same time, the top of the water tank is equipped with a water inlet, and the inner wall of the water inlet is hinged with a baffle, which not only makes it convenient for staff to replenish the water source in time, but also closes the baffle when the equipment is running to prevent the water source in the water tank from splashing out or being contaminated by external dust, thus ensuring the cleanliness of the circulating water source.

[0017] 3. By adopting a coaxial nested structure of inner cylinder and sleeve, arc-shaped filter screens are fixed at both openings on the outer surface of the sleeve, and the sleeve is tightly fitted to the inner wall of the inner cylinder. This ensures that when the water pipe draws water from the water tank, all water flow must pass through the arc-shaped filter screen. The arc-shaped filter screen can effectively intercept dust, dirt and other impurities in the water, preventing impurities from entering the water pipe, the first annular pipe, the second annular pipe and the inside of the spray head. This avoids problems such as poor spraying and reduced dust suppression effect caused by spray head blockage. At the same time, it can also prevent impurities from wearing down the water pump, pipe interface and other components in the pipeline, reducing the equipment failure rate.

[0018] 4. When the drive source drives the drive disc to rotate, the drive block on the drive disc contacts the side block through the arc surface, pushing the side block to slide up and down in the sliding opening of the support frame. This, in turn, drives the first side plate, lifting block, second side plate, and sleeve to move up and down synchronously. When the sleeve moves upward, the inner cylinder and the sleeve generate an upward impact force. The water flow in the water tank will form a downward impact force on the dirt attached to the surface of the arc-shaped filter screen, initially cleaning the filter screen. When the drive block disengages from the side block, the reset spring drives the first side plate and related components to reset, and the sleeve moves downward. At this time, the water flow near the inner cylinder will form an upward impact force on the filter screen, further washing away the dirt remaining on the surface of the filter screen, realizing the self-cleaning of the filter screen.

Detailed Implementation

[0026] The following will refer to the attached reference. Figures 1 to 6 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0027] A water spraying device for heatstroke prevention and dust suppression in construction, such as Figure 1-6 As shown, the system includes a movable base 10 and a water tank 11. The water tank 11 is mounted on the movable base 10 and can store water. The water can be discharged from the water tank 11 to reduce dust in the air. A hollow cylinder 12 is provided on the upper side of the water tank 11, and a support frame 14 is installed between the top of the water tank 11 and the outer wall of the hollow cylinder 12. The support frame 14 has an annular cavity, and the outer wall of the hollow cylinder 12 is fixed to the cavity wall of the annular cavity. The support frame 14 is used to support the hollow cylinder 12 to maintain its stability. A ventilation cylinder 13 is fixed to one side of the hollow cylinder 12, and the ventilation cylinder 13 is connected to... The hollow cylinder 12 is connected to the water tank 11 and the top of the ventilation cylinder 13 are fixedly connected to the dropper 15. The water and dirt generated by dust suppression inside the ventilation cylinder 13 can fall into the water tank 11 through the dropper 15 to achieve repeated use of the water. The bottom of the ventilation cylinder 13 is provided with a dropper 16, and the dropper 16 is located inside the dropper 15. That is, the water and dirt generated by dust suppression inside the ventilation cylinder 13 can fall into the dropper 15 through the dropper 16. The hollow cylinder 12 is equipped with a dust removal component 20 for dust suppression in the air to purify the air.

[0028] Since the top of the water tank 11 has a water inlet and the inner wall of the water inlet is hinged with a baffle, when the dust removal component 20 removes dust from the air, the baffle is opened first to inject water into the interior of the water tank 11, and then the moving seat 10 is pushed so that the dust removal component 20 can remove dust from the air in different areas.

[0029] The dust removal assembly 20 includes a first annular pipe 21 installed on the hollow cylinder 12. A plurality of first spray heads 22 are installed on the outer surface of the first annular pipe 21, and the plurality of first spray heads 22 are arranged in a ring on the outer surface of the first annular pipe 21. A water suction pipe 23 is fixedly connected to the bottom of the first annular pipe 21, and the end of the water suction pipe 23 away from the first annular pipe 21 extends into the interior of the water tank 11. An induced draft fan 24 is installed inside the hollow cylinder 12.

[0030] When dust is suppressed in the air, a water pump is installed on the water pump pipe 23. The water pump draws water from the water tank 11 through the water pump pipe 23 and then flows to the first annular pipe 21 and is sprayed out through the first spray head 22. The induced draft fan 24 can draw air and make the airflow to the ventilation cylinder 13 and the hollow cylinder 12. Together with the water sprayed by the first spray head 22, it suppresses the dust in the air.

[0031] The inner wall of the ventilation cylinder 13 is equipped with a second annular pipe 25. Multiple second spray heads 26 are installed on the inner annular surface of the second annular pipe 25. The multiple second spray heads 26 are arranged in a ring on the outer surface of the first annular pipe 21. A connecting water pipe 27 is fixedly connected to the outer wall of the second annular pipe 25. The end of the connecting water pipe 27 away from the second annular pipe 25 passes through the ventilation cylinder 13 and is fixedly connected to the outer wall of the water pumping pipe 23.

[0032] It should be noted that when the water pumping pipe 23 draws water, a portion of the water inside the water pumping pipe 23 can flow into the interior of the second annular pipe 25 through the connecting water pipe 27 and be sprayed out through the second spray head 26, which can pre-treat and reduce dust in the gas flowing into the ventilation cylinder 13.

[0033] A filter mechanism 30 is installed on the water tank 11 to prevent dirt from entering the inside of the water pipe 23, thereby maintaining the dust reduction performance of the water source.

[0034] The filtration mechanism 30 includes a filter assembly 31 and an anti-clogging assembly 32. The filter assembly 31 can prevent dirt from entering the inside of the water pump pipe 23, while the anti-clogging assembly 32 can maintain the filtration performance of the filter assembly 31.

[0035] The filter assembly 31 includes an inner cylinder 3101 fixedly connected to the bottom of the water pump pipe 23. The bottom end of the inner cylinder 3101 penetrates the top of the water tank 11 and extends into the interior of the water tank 11. The diameter of the inner cylinder 3101 is the same as the diameter of the water pump pipe 23. The interior of the inner cylinder 3101 is connected to the interior of the water pump pipe 23. A sleeve 3102 is provided inside the inner cylinder 3101. The sleeve 3102 is coaxially arranged with the inner cylinder 3101. The inner wall of the inner cylinder 3101 fits against the outer wall of the sleeve 3102. The sleeve 3102 is slidably connected inside the inner cylinder 3101. Two openings 3103 are opened on the outer surface of the sleeve 3102. An arc-shaped filter screen 3104 is fixed on the inner wall of each of the two openings 3103.

[0036] When the water pipe 23 draws water from the water tank 11, the arc-shaped filter screen 3104 can filter the water inside the water tank 11, thereby preventing dirt from entering the water tank 11 when the water pipe 23 draws water from the water tank 11, thus preventing the first spray head 22 from being blocked by dirt and causing wear.

[0037] The anti-clogging component 32 includes a first side plate 3201 fixed to the outer surface of the inner cylinder 3101, a second side plate 3202 fixed to the outer wall of the sleeve 3102, a lifting block 3203 fixed to the top of the second side plate 3202, two limiting ports 3204 adapted to the lifting blocks 3203 being opened on the top of the water tank 11, and the lifting blocks 3203 being slidably connected to the interior of the corresponding limiting ports 3204, with the top of the lifting blocks 3203 extending out of the limiting ports 3204 and fixed to the bottom of the first side plate 3201. The first side plate 3201 has a corresponding opening for the inner cylinder 3101. The limiting hole 3205 is adapted to the 01 phase, and the outer wall of the inner cylinder 3101 is fixed on the inner wall of the corresponding limiting hole 3205. The maximum diameter of the water pumping pipe 23 is less than the minimum diameter of the limiting hole 3205. When the first side plate 3201 moves upward, the first side plate 3201 drives the lifting block 3203 to slide inside the limiting port 3204. The lifting block 3203 drives the second side plate 3202 to move upward, so that the sleeve 3102 moves upward inside the inner cylinder 3101 to contact the water source in different areas for extraction, avoiding blockage on the surface of the arc-shaped filter screen 3104.

[0038] A reset spring 3207 is fixed between the bottom of the first side plate 3201 and the top of the water tank 11 to support the first side plate 3201 so as to drive the first side plate 3201 to reset.

[0039] A side block 3208 is fixed to one side of the first side plate 3201. A sliding opening 3209 adapted to the side block 3208 is provided on the support frame 14. The side block 3208 is slidably connected inside the corresponding sliding opening 3209. A drive disk 3211 is provided on one side of the side block 3208. A drive block 3212 is fixed on the surface of the drive disk 3211. The drive block 3212 has an arc-shaped surface. When the drive disk 3211 rotates, the drive block 3212 can contact the side block 3208 and drive the side block 3208 to move upward inside the sliding opening 3209, thereby driving the first side plate 3201 to slide up and down.

[0040] A drive source 3213 is fixed on one side of the drive disk 3211, and the output end of the drive source 3213 is fixed in the middle of the drive disk 3211.

[0041] When the output end of the drive source 3213 drives the drive disk 3211 to rotate around its axis, the arc surface of the drive block 3212 contacts the arc surface of the side block 3208, causing the side block 3208 to move upward inside the sliding port 3209. At the same time, the side block 3208 drives the first side plate 3201 to move upward, and the first side plate 3201 drives the lifting block 3203 to move upward inside the limiting port 3204. The lifting block 3203 drives the sleeve 3102 to move upward inside the inner cylinder 3101 through the second side plate 3202. At this time, the inner cylinder 3101 has an upward force. At this time, the water inside the water tank 11 will impact the dirt attached to the surface of the arc-shaped filter screen 3104, thereby preventing the surface of the arc-shaped filter screen 3104 from being blocked. At the same time, the water inside the water tank 11 can flow into the interior of the water pumping pipe 23 through the opening 3103.

[0042] As the drive disc 3211 continues to rotate, after the side block 3208 disengages from the drive block 3212, the reset spring 3207 drives the first side plate 3201 to reset, and at the same time the inner cylinder 3101 moves downward. At this time, the arc-shaped filter screen 3104 has a downward impact force, and the water near the inner cylinder 3101 can impact the arc-shaped filter screen 3104 upward, thereby washing away the dirt attached to the surface of the arc-shaped filter screen 3104, thus maintaining the filtration performance of the arc-shaped filter screen 3104.
