Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, specifically a high-efficiency dust removal device for engineering construction. Background Technology

[0002] During building construction, key processes such as earthwork excavation, building material stockpiling, waste soil transportation, and structural chiseling generate a large amount of fugitive dust. This not only degrades air quality at the construction site but also easily leads to excessive concentrations of air pollutants in the surrounding area, making it a key target for environmental management and civilized construction in building projects. Currently, commonly used high-efficiency dust suppression devices in the building construction field are mainly divided into two categories: mist cannons and perimeter spraying. Among them, mist cannons are used for precise dust suppression at fixed points and are mainly applied to scenarios where dust is concentrated, such as earthwork excavation, backfilling, and sand and gravel stockpiling. The operating environment is mostly concentrated in local high-dust points such as large-scale mechanical construction excavation sites and concentrated sand and gravel aggregate stockpiling areas. Due to the intermittent and sudden nature of their operation, mist cannons are generally used non-continuously, resulting in most on-site mist cannon dust suppression devices being used for extended periods. Currently, the equipment is idle and has a low overall utilization rate. The perimeter spray system mainly serves to suppress dust in the entire construction site area. It achieves large-scale dust coverage and control by continuously deploying along the perimeter fence. However, the installation process of this device is relatively cumbersome. It is necessary to use cable ties and other fixing components at fixed intervals to bind the spray pipes to the pre-buried support poles or the top of the construction fence. When adjusting the working conditions or changing the site later, it is very inconvenient to disassemble and re-lay the pipes, and the equipment has poor flexibility in disassembly and assembly. Therefore, this invention provides a high-efficiency dust removal device for engineering construction. Summary of the Invention

[0003] The purpose of this invention is to provide a high-efficiency dust removal device for engineering construction, so as to solve the problems mentioned in the background art.

[0004] The technical solution of this invention is: a high-efficiency dust removal device for engineering construction, comprising a mobile base, a support frame fixedly installed on the top of the mobile base, a rear air duct rotatably connected between the inner sidewalls of both ends of the support frame, a front air duct fixedly installed at the front end of the rear air duct, and a plurality of electric telescopic rods circumferentially fixedly installed at equal intervals on the outer ring wall of the air outlet of the front air duct, an annular base fixedly installed between the telescopic ends of the plurality of electric telescopic rods, and two conical annular water tanks rotatably connected to the outer ring wall of the annular base, each of the conical annular water tanks having a water delivery hose connected to its conical surface, and the plurality of water delivery hoses spirally wound around the conical surface of the corresponding conical annular water tank, with a plurality of atomizing nozzles fixedly installed at equal intervals on the wall of each water delivery hose. This device integrates the core advantages of traditional fog cannon dust suppression and perimeter spraying, using a fog cannon dust suppression device as the main structure, and evenly distributing atomizing nozzles along the hoses at equal intervals, taking into account both the needs of precise dust suppression at fixed points and regional dust suppression across the entire area, and is suitable for use in multiple scenarios of building construction.

[0005] Preferably, a frame is fixedly installed on the side wall of the support frame, a motor is fixedly installed on the side wall of the frame, a worm gear is fixedly installed at the output end of the motor, and a worm wheel meshing with the worm gear is fixedly installed on the side wall of the rear air duct. The rotating part at the top of the movable base can drive the support frame, the rear air duct and the front air duct to rotate in the horizontal direction. The motor can drive the worm wheel, the rear air duct and the front air duct to rotate in the vertical direction through the worm gear, thereby achieving a multi-angle directional dust suppression effect.

[0006] Preferably, two symmetrical multi-stage electric telescopic rods are fixedly installed on the side walls of both ends of the front air duct, and two symmetrical folding frames are fixedly installed on the side walls of both ends of the front air duct. The two multi-stage electric telescopic rods are respectively fixedly connected to the ends of the corresponding folding frames through connecting rods, and the ends of the two folding frames that are far apart from each other are respectively fixedly connected to the ends of the corresponding water supply pipes through connecting rods. Several support rods are fixedly fixed at equal intervals on the side walls of the two folding frames, and a support base is fixedly installed on the side of each support rod that is far away from the corresponding folding frame. When the construction site requires full-area regional dust suppression, the motor drives the worm gear, rear air duct, and front air duct to rotate vertically through the worm gear, so that the air duct and front air duct are in a vertically upward posture; then the multi-stage electric telescopic rods drive the ends of the folding frames to move, realizing the lateral extension of the folding frames. The connecting rod connects to one end of the water supply hose, allowing the hose, originally tightly wound in a conical spiral shape around the corresponding conical annular water tank, to be smoothly stretched and flattened to the side, resulting in the atomizing nozzles being neatly arranged laterally at equal intervals. The electric telescopic rod moves the annular base and two sets of conical annular water tanks on its surface backward synchronously, thus smoothly stretching and flattening the conical spiral-shaped water supply hose. Multiple devices working together can complete the overall dust suppression spraying in the construction enclosure area. This mode requires no additional external water supply pipelines, relying directly on the device's built-in water tank for water supply, significantly reducing on-site deployment difficulty. Furthermore, support rods and support bases are installed at equally spaced nodes on the support frame, providing stable and active support for the stretched hose. No tedious manual binding and fixing is required; the entire process is simple and efficient, saving significant labor and time costs.

[0007] Preferably, each of the conical annular water tanks is rotatably connected to a movable ring plate on its back, and each movable ring plate is connected to a second water supply hose. A column is fixedly installed on the top of the front air duct annular wall, and several second water supply hoses are fixedly installed on the column. Before use, the second water supply hose is connected to the output end of the water pump in the movable base via a water pipe. When precise dust suppression is required, the first water supply hose is tightly wound around the surface of the corresponding conical annular water tank in a conical spiral shape as shown in the figure. During use, the water pump in the movable base delivers dust suppression water to the second water supply hose and the interior of the conical annular water tank through a water pipe. Subsequently, the dust suppression water enters the atomizing nozzle through the first water supply hose and is sprayed out in the form of water mist. At the same time, the fan in the rear air duct blows out airflow carrying the sprayed water mist for directional spraying. This measure can accurately suppress local high-concentration dust at specific locations, and specifically solve the dust problem at locations such as earthwork excavation and building material stacking.

[0008] Preferably, an inner gear ring and an outer gear ring are fixedly installed on the annular surfaces of the two conical annular water tanks, respectively. A second motor is fixedly installed on the annular base. A drive gear that meshes with both the inner and outer gear rings is fixedly installed at the output end of the second motor. The drive gear is located between the inner and outer gear rings. The second motor drives the drive gear to rotate, and the drive gear drives the inner and outer gear rings to rotate in opposite directions, thereby causing the two sets of conical annular water tanks to rotate in opposite directions, thereby assisting the water delivery hoses on their surfaces to be smoothly stretched and flattened to the side.

[0009] Preferably, several limiting buckles are provided on the front and rear side walls of the two conical annular water tanks. The limiting buckles ensure that the water delivery hose can always be tightly wrapped around the surface of the corresponding conical annular water tank when it is wound twice.

[0010] Preferably, both the plurality of water supply hoses I and the plurality of water supply hoses II are rubber-plastic composite high-pressure pipes.

[0011] This invention provides an improved high-efficiency dust removal device for engineering construction, which has the following improvements and advantages compared with the prior art: This device combines the core advantages of traditional fog cannons for dust suppression with perimeter spraying. When precise dust suppression is needed at specific locations, the flexible hose is tightly wound in a conical spiral around the air outlet at the front of the ventilation duct, with each atomizing nozzle forming a multi-dimensional, uniform distribution pattern in space. During operation, the atomizing nozzles spray water mist, which is directed and sprayed under the airflow driven by the built-in fan in the ventilation duct. This can precisely suppress high-concentration dust at specific locations, effectively solving dust problems at sites such as earthwork excavation and building material stacking. When area-wide dust suppression is required at the construction site, the conical spiral-wound flexible hose can be smoothly stretched and flattened to both sides using the folding frames at both ends, so that the atomizing nozzles are evenly spaced and neatly arranged laterally. Multiple units working together can effectively suppress dust by spraying water across the entire construction site enclosure. This method eliminates the need for external water supply lines, relying directly on the unit's built-in water tank, significantly reducing on-site setup difficulty. Furthermore, the support frame features integrated support and limiting components at evenly spaced nodes, providing stable and active support for the stretched hoses. This eliminates the need for tedious manual binding and fixing, ensuring a simple and efficient assembly and disassembly process that saves considerable manpower and time. The device's flexible switching between dual operating modes effectively addresses the industry pain points of high idle rates and low utilization rates of traditional single dust suppression equipment, enhancing its overall value.

Detailed Implementation

[0014] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] This invention provides an improved high-efficiency dust removal device for engineering construction. The technical solution of this invention is as follows: like Figures 1-12As shown, a high-efficiency dust removal device for engineering construction includes a mobile base 1. A support frame 2 is fixedly installed on the top of the mobile base 1. A rear air duct 3 is rotatably connected between the inner sidewalls of both ends of the support frame 2. A front air duct 4 is fixedly installed at the front end of the rear air duct 3. Several electric telescopic rods 5 are circumferentially fixedly installed at equal intervals on the outer ring wall of the air outlet of the front air duct 4. An annular base 6 is fixedly installed between the telescopic ends of the several electric telescopic rods 5. Two conical annular water tanks 7 are rotatably connected to the outer ring wall of the annular base 6. A water supply hose 8 is connected to the conical surface of each conical annular water tank 7, and several water supply hoses 8 are spirally wound around the conical surface of the corresponding conical annular water tank 7. Several atomizing nozzles 9 are fixedly installed at equal intervals on the wall of each water supply hose 8. A movable ring plate 18 is rotatably connected to the back of each conical annular water tank 7, and a water supply hose 9 is connected to each movable ring plate 18. Pipe 2 19, the top of the front air duct 4 is fixedly installed with a column 20, and several water supply hoses 2 19 are fixedly installed on the column 20. Several water supply hoses 1 8 and several water supply hoses 2 19 are all rubber and plastic composite high pressure pipes. Before use, the water supply hoses 2 19 are connected to the output end of the water pump in the mobile base 1 through the water pipe. When precise dust suppression is required, the water supply hoses 1 8 are tightly wrapped in a conical spiral shape on the surface of the corresponding conical annular water tank 7 as shown in the figure. During use, the water pump in the mobile base 1 delivers dust suppression water to the water supply hoses 2 19 and the conical annular water tank 7 through the water pipe. Then the dust suppression water enters the atomizing nozzle 9 through the water supply hoses 1 8 and is sprayed out in the form of water mist. At the same time, the fan in the rear air duct 3 blows out airflow to carry the sprayed water mist for directional spraying. This can accurately achieve the local high concentration dust suppression and specifically solve the dust problem at the points of earthwork excavation, building material stacking, etc. Furthermore, a frame 10 is fixedly installed on the side wall of the support frame 2, a motor 11 is fixedly installed on the side wall of the frame 10, a worm gear 12 is fixedly installed at the output end of the motor 11, and a worm wheel 13 that meshes with the worm gear 12 is fixedly installed on the side wall of the rear air duct 3. The rotating part at the top of the movable base 1 can drive the support frame 2, the rear air duct 3 and the front air duct 4 to rotate in the horizontal direction. The motor 11 can drive the worm wheel 13, the rear air duct 3 and the front air duct 4 to rotate in the vertical direction through the worm gear 12, thereby achieving a multi-angle directional dust suppression effect.

[0016] Furthermore, two symmetrical multi-stage electric telescopic rods 14 are fixedly installed on the side walls of both ends of the front air duct 4, and two symmetrical folding frames 15 are fixedly installed on the side walls of both ends of the front air duct 4. The two multi-stage electric telescopic rods 14 are respectively fixedly connected to the ends of the corresponding folding frames 15 through connecting rods, and the ends of the two folding frames 15 that are far apart from each other are respectively fixedly connected to the ends of the corresponding water supply pipes through connecting rods. Several support rods 16 are fixedly fixed at equal intervals on the side walls of the two folding frames 15, and a support base 17 is fixedly installed on the side of each support rod 16 that is far away from the corresponding folding frame 15. When the construction site requires full-area coverage... During dust suppression, the motor 11 drives the worm gear 13, rear air duct 3, and front air duct 4 to rotate vertically via the worm gear 12, causing the air ducts and front air duct 4 to be in a vertically upward posture. Subsequently, the multi-stage electric telescopic rod 14 drives the end of the folding frame 15 to move, realizing the lateral extension of the folding frame 15. Since the end of the folding frame 15 is connected to the end of the water supply hose 8 via the connecting rod, the water supply hose 8, which was originally tightly wrapped in a conical spiral on the surface of the corresponding conical annular water tank 7, is smoothly stretched and flattened to the side, so that the atomizing nozzles 9 are arranged horizontally in an evenly spaced manner. The electric telescopic rod 5 drives the annular base. 6 and its two sets of conical annular water tanks 7 on its ring surface move backward synchronously, so as to smoothly stretch and flatten the conical spiral water delivery hose 19; multiple sets of devices work together to complete the overall spraying dust suppression of the construction enclosure area. This mode does not require additional external water supply pipelines, and directly relies on the water tanks built into the device for water supply, which greatly reduces the difficulty of on-site deployment; in addition, support rods 16 and support bases 17 are set at equally spaced nodes of the support frame 2. This can form a stable active support for the stretched hose, without the need for tedious manual binding and fixing. The entire process requires no manual intervention, and the disassembly and assembly process is simple and efficient, which greatly saves labor and time costs; two An inner gear ring 21 and an outer gear ring 22 are fixedly installed on the annular surface of the conical annular water tank 7. A motor 23 is fixedly installed on the annular base 6. A drive gear 24 that meshes with both the inner gear ring 21 and the outer gear ring 22 is fixedly installed at the output end of the motor 23. The drive gear 24 is located between the inner gear ring 21 and the outer gear ring 22. The motor 23 drives the drive gear 24 to rotate. The drive gear 24 drives the inner gear ring 21 and the outer gear ring 22 to rotate in opposite directions, thereby causing the two sets of conical annular water tanks 7 to rotate in opposite directions, so as to assist the water delivery hose 8 on its surface to be smoothly stretched and flattened to the side.

[0017] Furthermore, several limiting buckles 25 are provided on the front and rear side walls of the two conical annular water tanks 7. The limiting buckles 25 ensure that the water supply hose 19 can always be tightly wrapped around the surface of the corresponding conical annular water tank 7 when it is wound.

[0018] Working principle: Before use, connect the water delivery hose 19 to the water pump output in the mobile base 1 via a water pipe; when precise dust suppression is required, the water delivery hose 8 is tightly wound in a conical spiral shape around the surface of the corresponding conical annular water tank 7 as shown in the figure; during use, the water pump in the mobile base 1 delivers dust suppression water to the water delivery hose 19 and the conical annular water tank 7 through the water pipe; then the dust suppression water enters the atomizing nozzle 9 through the water delivery hose 8 and is sprayed out in the form of water mist, while the rear wind... The fan in cylinder 3 blows out airflow carrying water mist for directional spraying. This can accurately suppress local high-concentration dust at specific points, and specifically solve the dust problem at locations such as earthwork excavation and building material stacking. The rotating part at the top of the movable base 1 can drive the support frame 2, the rear air duct 3 and the front air duct 4 to rotate horizontally. The motor 11 can drive the worm wheel 13, the rear air duct 3 and the front air duct 4 to rotate vertically through the worm gear 12, thereby achieving a multi-angle directional dust suppression effect. When dust suppression is required across the entire construction site, the installed motor 11 drives the worm gear 13, rear air duct 3, and front air duct 4 to rotate vertically via the worm gear 12, causing the air ducts and front air duct 4 to be in a vertically upward posture. Subsequently, the installed multi-stage electric telescopic rod 14 drives the end of the folding frame 15 to move, realizing the lateral extension of the folding frame 15. Since the end of the folding frame 15 is connected to the end of the water supply hose 8 via the connecting rod, the water supply hose 8, which was originally tightly wrapped in a conical spiral on the surface of the corresponding conical annular water tank 7, is smoothly stretched and flattened to the side, so that the atomizing nozzles 9 are arranged horizontally in an evenly spaced manner. At the same time, the installed motor 2 23 drives the drive gear 24 to rotate, which in turn drives the inner gear ring 21 and the outer gear ring 22 to rotate in opposite directions. This causes the two sets of conical annular water tanks 7 to rotate in opposite directions, thereby assisting the water delivery hose 8 on their surface to be smoothly stretched and flattened to the side. In addition, the electric telescopic rod 5 drives the annular base 6 and the two sets of conical annular water tanks 7 on its annular surface to move backward synchronously, thereby allowing the conical spiral-arranged water delivery hose 19 to be smoothly stretched and flattened. With the cooperation of multiple devices, the overall spraying dust suppression of the construction enclosure area can be completed. This mode does not require an additional external water supply pipeline, and directly relies on the water tank of the device for water supply. This significantly reduces the difficulty of on-site deployment. Furthermore, support rods 16 and support bases 17 are installed at equidistant nodes on the support frame 2, providing stable active support for the stretched hose. This eliminates the need for tedious manual binding and fixing, requiring no manual intervention throughout the process. The assembly and disassembly process is simple and efficient, greatly saving labor and time costs. This device effectively solves the industry pain points of high idle rates and low utilization rates of traditional single dust suppression equipment through flexible switching between dual operating modes, enhancing the equipment's value. When switching to fog cannon mode, the multi-stage electric telescopic rod 14 drives the folding frame 15 to fold again, and the second motor 23 drives the internal gear ring 21 through the drive gear 24. The outer gear ring 22 and the corresponding conical annular water tank 7 are reset, so that the water delivery hose 18 is re-wound in a spiral shape around the surface of the corresponding conical annular water tank 7. The electric telescopic rod 15 drives the annular base 6 and the two sets of conical annular water tanks 7 on its annular surface to move forward synchronously, so that the water delivery hose 219 is wrapped in a conical shape around the surface of the corresponding conical annular water tank 7, avoiding interference between adjacent atomizing nozzles 9. It should be noted that since the conical annular water tank 7 is rotatably connected to the corresponding movable ring plate 18 and the water delivery hose 219, the rotation and translation of the conical annular water tank 7 will not interfere with the delivery of dust suppression water. This device can also be flexibly deployed at the vehicle entrances and exits of construction sites. With its large coverage area after being extended and straightened, the hose can quickly complete the dust suppression operation on both sides of the vehicles leaving the site. When switched to the mist cannon mode, it can also accurately suppress dust in deeper spaces such as the inside of the tires, which are difficult to cover by conventional spraying. This achieves diversified and all-round vehicle dust suppression effects, which not only greatly shortens the vehicle washing and dust suppression time, but also significantly improves the thoroughness of dust suppression, further expanding the application scenarios of the device and improving the overall utilization efficiency.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
