Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal technology, specifically a dust removal device for construction sites. Background Technology
[0002] Construction site dust removal devices are used at construction sites to reduce airborne pollutants such as dust and particulate matter, improve air quality in the construction environment, and protect the health of people in the surrounding area.
[0003] In current construction site dust control methods, fog cannons are often used to generate water mist to absorb and remove dust. Traditional fog cannons typically generate water mist by impacting a baffle, which is then blown out by wind. This method can quickly generate water mist to absorb dust. However, traditional fog cannons also blow out water that has not yet formed a mist through the nozzle, causing some water to be blown out too far or not to have any dust removal effect, thus wasting resources.

[0010] Optionally, a baffle fixing block is fixedly connected to the top of the other end of the rotating nozzle, and a baffle is rotatably connected to the bottom of the baffle fixing block.

[0013] This utility model provides a dust removal device for construction sites, which has the following beneficial effects:
[0014] 1. This dust removal device at the construction site, through the setting of rotating nozzles, ensures that when the ground is uneven, the rotating nozzles, due to the gravity of the return channel and baffles, keep the baffles vertically downward, thus improving the baffles' effectiveness. Through the coordinated design of the baffles, the inclined design on the back side of the baffles allows the baffles to be pushed to both sides when water is sprayed from the rotating nozzles, resulting in a water jet. When the baffles fall downwards due to gravity, the water jet breaks up. The water jet impacts the baffles, forming a water mist. This break in the water jet effectively reduces the absorption of water mist during continuous spraying, thereby improving the water mist generation efficiency and achieving the goal of improving dust removal efficiency.
[0015] 2. This construction site dust removal device, through the design of its fan blades, enables it to blow out the water mist formed at the baffle using the airflow generated by the fan blades, thereby achieving the effect of dust removal. With the coordinated design of the return trough and return pipe, during operation, the water column at the rotating nozzle and some of the water mist absorbed by the water column will fall into the return trough due to the obstruction of the baffle, and then flow into the water tank through the return pipe. This effectively recovers the water flow that has not formed water mist, achieving resource conservation while increasing the amount of water mist generated and the dust removal efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example
[0025] Please see Figures 1 to 6 The present invention provides a technical solution: a dust removal device for construction sites, including a base plate 1, with casters installed below the base plate 1, a water tank 2 fixedly connected above the base plate 1, a water inlet 201 opened on the upper surface of the water tank 2, a bracket 3 fixedly connected to one side of the upper surface of the water tank 2, a turntable 13 rotatably connected to the middle of the upper surface of the water tank 2, a water pump 12 fixedly connected inside the turntable 13, a water pump pipe 14 fixedly connected below the water pump 12, the other end of the water pump pipe 14 located at the bottom of the inside of the water tank 2, a connecting pipe 11 fixedly connected above the water pump 12, fixing blocks 16 fixedly connected to both sides of the turntable 13, a barrel fixing block 15 rotatably connected above the fixing blocks 16, a barrel 4 fixedly connected above the barrel fixing block 15, a handle fixedly connected to both sides of one end of the barrel 4, and an inner barrel fixing plate 9 fixedly connected inside the barrel 4.
[0026] Specifically, the design of the bracket 3 allows the cannon barrel 4 to be placed on the bracket 3 when not in use, making it easy to put away. The design of the turntable 13 and the cannon barrel fixing block 15 allows the cannon barrel 4 to rotate up and down and horizontally, making the cannon barrel 4 more flexible.
[0027] Please see Figures 1 to 2 A motor 5 is fixedly connected to the same side of the barrel 4. A rotating shaft 6 is rotatably connected to one side of the motor 5. A fan blade 7 is fixedly connected to the outer surface of the rotating shaft 6. A filter hole 401 is provided at the same end of the barrel 4. A barrel mouth is provided at the other end of the barrel 4. The barrel mouth has a conical design.
[0028] Specifically, by setting up the motor 5 and the fan blades 7, the dust removal device at the construction site is able to blow out the water mist formed at the baffle 21 through the wind generated by the fan blades 7, thereby achieving the effect of dust removal.
[0029] Please see Figures 3 to 6 An inner cannon 8 is fixedly connected to the upper part of the inner cannon barrel fixing plate 9. A cone block 10 is fixedly connected to one end of the inner cannon barrel 8. A rotating nozzle 17 is rotatably connected to the other end of the inner cannon barrel 8. The inner diameter of the rotating nozzle 17 gradually decreases from the end of the inner cannon barrel 8 to the other end of the rotating nozzle 17. A baffle fixing block 18 is fixedly connected to the upper part of the other end of the rotating nozzle 17. A baffle 19 is rotatably connected to the lower part of the baffle fixing block 18. The diameter side of the back of the baffle 19 is designed with a chamfer. There are several baffles 19. Several baffles 19 are evenly distributed in a symmetrical manner below the baffle fixing block 18. A return channel 20 is fixedly connected to the lower part of the other end of the rotating nozzle 17. A baffle 21 is fixedly connected to the upper part of the front of the return channel 20. A return pipe 22 is fixedly connected inside the return channel 20. The other end of the return pipe 22 is connected to the inside of the water tank 2. The return pipe 22 and the connecting pipe 11 are retractable hoses.
[0030] Specifically, by setting up the rotating nozzle 17, the dust removal device at the construction site can ensure that when the ground is uneven, the rotating nozzle 17, due to the gravity of the return channel 20 and the baffle 21, keeps the baffle 19 vertically downward, thus enabling the baffle 19 to work better. Through the cooperative arrangement of the baffle 19 and the baffle 21, during use, the inclined design on the back side of the baffle 19 can push the baffle 19 to both sides when the rotating nozzle 17 sprays water, at which time a water column is sprayed out. When the baffle 19 falls downward due to gravity, the water column is interrupted, and the water column impacts the baffle. After the water column is interrupted, water mist is formed. When the water column is interrupted, the absorption of water mist when the water column is continuously sprayed is effectively reduced, thereby improving the water mist generation efficiency and achieving the purpose of improving the dust removal efficiency. Through the cooperation of the return tank 20 and the return pipe 22, during use, the water column at the rotating nozzle 17 and some of the water mist absorbed by the water column can fall into the return tank 20 due to the obstruction of the baffle 21, and then flow into the water tank 2 through the return pipe 22. This can achieve the function of recycling the water flow that has not formed water mist, thereby saving resources and increasing the amount of water mist generated.
[0031] In use, the dust removal device is first pushed to the corresponding position using the bottom casters. If the ground is flat, the rotating nozzle 17 will remain stationary. If the ground is uneven, the rotating nozzle 17 will rotate due to the gravity of the return channel 20 and baffle 21 connected below, ensuring that the baffle 19 remains perpendicular to the ground, thus guaranteeing the efficiency of the baffle 19. Then, the water pump 12 and motor 5 are started. Starting the water pump 12 allows water to enter the pump through the water pipe 14 and then be transmitted to the inner barrel 8 through the connecting pipe 11. From there, the water is transmitted to the rotating nozzle 17. As the inner diameter of the rotating nozzle 17 continuously decreases, the rotating nozzle... When the water pressure at the outlet increases, the baffle plate 19 will pop out to both sides when the water column comes into contact with it. At this time, part of the water column is blocked. When the baffle plate 19 pops out, the water column sprays out normally and forms water mist after hitting the baffle 21. At the same time, due to the obstruction of the baffle plate 19, the water column behind is reduced or blocked, thereby reducing the absorption of water mist by the water column. After the water mist is formed, the motor 5 is started, which can generate wind inside the cannon barrel 4, so that the water mist flies out from one end of the cannon barrel 4, thereby completing the purpose of dust removal. During use, the operator only needs to hold the handle and can rotate it up and down through the cannon barrel fixing block 15 and rotate it horizontally through the rotating disk 13.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
