Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of environmental protection engineering construction, in particular to a building dry fog dust suppression device. BACKGROUND

[0002] The building dry fog dust suppression device is an efficient, energy-saving and environmentally friendly device. It realizes dust suppression effect by atomizing water into micron-sized particles and combining with dust. This device uses a high-pressure system to disperse water into extremely fine mist. These tiny water droplets can quickly capture dust particles in the air, increasing their weight and causing them to settle, thereby effectively reducing the concentration of dust in the air. In environmental protection engineering construction, this device is widely used in multiple scenarios such as earth excavation, material loading and unloading, and concrete mixing. It is an important means of dust control. It not only protects the health of construction personnel and reduces environmental pollution, but also improves construction efficiency and ensures the smooth progress of the project. Therefore, the building dry fog dust suppression device has important significance in environmental protection engineering construction and is an indispensable green technology for modern construction sites.

[0003] For example, Chinese invention patent (CN116946763B) discloses a dry fog dust suppression device, which records: "a plurality of spray head mechanisms are arranged in a ring shape around the axis of the mounting ring. The spray head mechanism includes a sliding rod connected to the mounting ring, a mounting seat fixedly connected to the sliding rod, and a spray head two fixedly connected to the mounting seat. The position of the spray head can be adjusted, so that the dry fog is always around the material, and the material does not damage the equipment by impact." It also records: "When the material falls from the discharge port and forms a pile, flying dust is generated when the material is released from the discharge port and in the air. Especially when the material is falling in the air, flying dust is formed around the trajectory of the material falling from the discharge port. Therefore, the existing method is to use multiple spray heads arranged in a ring shape to spray. However, due to the difference in the released material, the amount and speed of the material release, and the different parabolic trajectories of the material falling, the use of ring-shaped spray cannot make the mist surround the material well, and the material may collide with the spray equipment, causing damage to the equipment."

[0004] In summary, the existing technology uses spray head one and spray head two to atomize and spray water, but this method has the following technical problems: In environmental protection engineering construction, water may contain silt, rust, mineral deposits or other suspended particles. When these particles pass through the small nozzle hole under high pressure, the nozzle hole may be blocked. If the operator replaces the spray head during the construction process, the spraying of dry fog needs to be temporarily suspended, which reduces the dust suppression effect on the environment. Therefore, the present application provides a building dry fog dust suppression device to solve the technical problems mentioned in the above patent and provides a new technical solution.

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] As mentioned in the background technology, during the construction of environmental protection projects, the water may contain mud, rust, mineral precipitation or other suspended particles. When these particles pass through the tiny nozzle holes under high pressure, the nozzle holes may be clogged. If the operator replaces the spray head during the construction of the environmental protection project, it is necessary to suspend the spraying of dry mist, thereby reducing the dust suppression effect on the environment.

[0022] In order to solve this technical problem, the present invention provides a building dry fog dust suppression device, which is used for dust suppression in building environments.

[0023] Specifically, please refer to Figures 1-8 , the building dry fog dust suppression device specifically includes: A mounting frame 1, an annular tube 2 is fixedly mounted on the bottom of the mounting frame 1, a protective shell 3 is fixedly mounted on the outer wall of the annular tube 2, a support frame 5 is fixedly connected to the bottom of the support frame 5, and a water pipe 4 is fixedly connected to the inner wall of the annular tube 2; The annular tube 2 is provided with a dust suppression mechanism 6 for spraying dry mist, and the dust suppression mechanism 6 includes a water tank 8, at least two groups of spraying components, an adjustment component and a driving component. The annular tube 2 is provided with a water tank 8 connected to the water pipe 4; The support frame 5 is provided with multiple adjustment mechanisms 7 for protecting the spraying assembly. The adjustment mechanisms 7 include a first rotating shaft 18, a second rotating shaft 19, a transmission assembly, two groups of protection assemblies, a reset assembly and a support assembly. The inner wall of the support frame 5 is respectively rotatably connected to the first rotating shaft 18 and the second rotating shaft 19.

[0024] The building dry fog dust suppression device provided by the present invention can control the water flow to be sprayed from one of the two corresponding atomizing nozzles 14 through the adjustment component. When spraying dry fog to suppress dust, dry fog can be sprayed by relying on one of the atomizing nozzles 14 in each group of spraying components. When some of the working atomizing nozzles 14 are blocked, the operator can rely on the driving component to drive the adjustment component to stop the working atomizing nozzles 14 in all the spraying components and activate another atomizing nozzle 14, thereby realizing emergency replacement of the atomizing nozzle 14, reducing the situation where the dust suppression effect on the environment is reduced due to the blockage of the working atomizing nozzle 14, and at the same time reducing the In case the operator replaces the atomizing nozzle 14 to stop spraying the dry mist and causes a lot of dust in the environment, the practicality of the device is improved. The driving component can also drive the adjustment component to make the two atomizing nozzles 14 in each spraying component work at the same time, so as to cope with the situation of a lot of dust in the building environment and achieve the effect of rapid dust suppression. When there is relatively little dust in the building environment, one atomizing nozzle 14 in each spraying component can be used normally to continuously suppress the dust in the building environment and reduce the consumption of water resources. The two spraying modes enable the device to be flexibly adjusted according to different scenarios, thereby improving the practicality of the device.

[0025] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Embodiment 1:

[0026] Please refer to Figures 1-7 , a building dry fog dust suppression device, comprising: A mounting frame 1 is provided, wherein an annular tube 2 is fixedly mounted on the bottom of the mounting frame 1, a protective shell 3 is fixedly mounted on the outer wall of the annular tube 2, a support frame 5 is fixedly connected to the bottom of the annular tube 2, the protective shell 3 is fixedly mounted on the bottom of the support frame 5, the top of the protective shell 3 is detachably mounted on the annular tube 2 by bolts, the bottom of the protective shell 3 is detachably mounted on the support frame 5 by bolts, and a water pipe 4 is fixedly connected to the inner wall of the annular tube 2; The annular tube 2 is provided with a dust suppression mechanism 6 for spraying dry mist. The dust suppression mechanism 6 includes a water tank 8, at least two groups of spraying components, an adjustment component and a drive component. The annular tube 2 is provided with a water tank 8 connected to the water pipe 4. The support frame 5 is provided with multiple adjustment mechanisms 7 for protecting the spraying assembly. The adjustment mechanism 7 includes a first rotating shaft 18, a second rotating shaft 19, a transmission assembly, two groups of protection assemblies, a reset assembly and a support assembly. The inner wall of the support frame 5 is respectively rotatably connected to the first rotating shaft 18 and the second rotating shaft 19.

[0027] The spray assembly includes a water flow chamber 9, and a water flow chamber 9 connected to the water tank 8 is opened in the annular tube 2. Two mounting heads 12 connected to the water flow chamber 9 are fixedly connected to the inner wall of the annular tube 2. The inner walls of the two mounting heads 12 are detachably installed with atomizing nozzles 14 through threads. The inner walls of the two atomizing nozzles 14 are detachably clamped with filter screens 13. The filter screens 13 can reduce the entry of small particles such as mud, rust or mineral precipitation in the water into the interior of the atomizing nozzle 14, thereby causing the atomizing holes on the atomizing nozzle 14 to be clogged. Since cleaning the particles on the filter screen 13 is simpler than cleaning the particles in the spray hole in the atomizing nozzle 14, it is convenient for subsequent maintenance of the device.

[0028] The adjustment component includes a three-way ball 10, which is rotatably connected to the water flow chamber 9. The outer wall of the three-way ball 10 is fixedly connected to a connecting rod 11. The rotation of the three-way ball 10 can affect the situation of the corresponding two atomizing nozzles 14 spraying dry mist, so that the combination of the two atomizing nozzles 14 has four situations, such as: one of the two atomizing nozzles 14 sprays, the two atomizing nozzles 14 spray together, and the two atomizing nozzles 14 do not spray. The connecting rod 11 is rotatably connected to the inner wall of the annular tube 2.

[0029] The driving assembly includes a double-sided gear ring 15, the outer wall of the annular tube 2 is rotatably connected to the double-sided gear ring 15, and one end of multiple connecting rods 11 located outside the annular tube 2 is fixedly connected to a first bevel gear 16, and multiple first bevel gears 16 are meshed with the top of the double-sided gear ring 15. A driving motor 17 is fixedly installed on the inner wall of the protective shell 3, and the inner wall of one of the first bevel gears 16 is fixedly connected to the output end of the driving motor 17. It is worth mentioning that the driving motor 17 is a servo motor with a self-locking function. This type of motor is a common existing technology. The driving motor 17 drives the first bevel gear 16 to rotate ninety degrees clockwise or counterclockwise each time according to the operator's control. In the program for setting the driving motor 17 to drive the three-way ball 10 to rotate, the position where the two corresponding atomizing nozzles 14 are not spraying is used as the basis. A maximum of three consecutive counterclockwise rotations can be performed, and each rotation angle is ninety degrees. Except for the reference state where clockwise rotation is not possible, clockwise rotation can be performed in other states, and the angle of each clockwise rotation is also ninety degrees.

[0030] Through the above structural design, after the device is installed, water enters the water tank 8 through the water pipe 4, and then the operator can control the drive motor 17 to drive the first bevel gear 16 connected thereto to rotate ninety degrees clockwise or counterclockwise, thereby making the double-sided gear ring 15 rotate outside the annular tube 2. The rotation of the double-sided gear ring 15 can drive the remaining first bevel gears 16 to rotate synchronously. The rotation of the first bevel gear 16 can drive the corresponding three-way ball 10 to rotate inside the water flow chamber 9 through the connecting rod 11, and then the situation of water passing through the water tank 8 and the water flow chamber 9 into the atomizing nozzle 14 can be changed, and then the situation of the two atomizing nozzles 14 in each spray assembly spraying water can be adjusted. The water enters the corresponding mounting head 12 through the water flow chamber 9, and then enters the inside of the atomizing nozzle 14 after being filtered through the filter 13, and then sprays out dry mist to suppress dust in the building environment. Example 2:

[0031] The building dry fog dust suppression device provided in Example 1 is further optimized. Specifically, Figures 8-10 As shown, the transmission assembly includes a second bevel gear 20, and the outer wall of the first rotating shaft 18 is fixedly connected to the second bevel gear 20. The second bevel gear 20 is engaged with the bottom of the double-sided gear ring 15. The pitch circle radius of the large end and the pitch circle radius of the small end of the second bevel gear 20 are respectively the same as the pitch circle radius of the large end and the pitch circle radius of the small end of the first bevel gear 16. Therefore, when the first bevel gear 16 rotates ninety degrees, the second bevel gear 20 rotates ninety degrees at the same time, but the two rotate in opposite directions.

[0032] The transmission assembly also includes a first transmission wheel 21, an outer wall of the second rotating shaft 19 is fixedly connected to the first transmission wheel 21, and an outer wall of the first rotating shaft 18 is fixedly connected to the second transmission wheel 23. The first transmission wheel 21 and the second transmission wheel 23 are connected by a transmission belt 22, wherein the first transmission wheel 21 and the second transmission wheel 23 can be pulleys, and the corresponding transmission belt 22 is a V-belt, or the first transmission wheel 21 and the second transmission wheel 23 are sprockets, and the transmission belt 22 is a chain. It is also worth mentioning that the radius of the first transmission wheel 21 is three times the radius of the second transmission wheel 23, so when the first rotating shaft 18 rotates ninety degrees, the second rotating shaft 19 rotates thirty degrees.

[0033] The protective assembly includes a half-protective cover 24. Two half-protective covers 24 are provided on the outside of the atomizing nozzle 14. Two fixed rods 26 are fixedly connected to the inner wall of the annular tube 2. The outer walls of the two fixed rods 26 are slidably connected to two sliding blocks 25. The top of the half-protective cover 24 is fixedly connected to the bottom of the sliding block 25. The four sliding blocks 25 are slidably connected to the inner wall of the annular tube 2. Two half-protective covers 24 are provided on the outside of the atomizing nozzle 14. The atomizing nozzle 14 can be protected when the atomizing nozzle 14 is not in use, reducing the adhesion of external dust to the outside of the atomizing nozzle 14. It is also worth mentioning that the two atomizing nozzles 14 in each group of spray assemblies are used at the same time only when the amount of environmental dust is large. When the amount of environmental dust decreases, the system will be adjusted back to the state where only one atomizing nozzle 14 in each group of spray assemblies is working. The time that the two atomizing nozzles 14 in each group of spray assemblies work at the same time should not be too long to avoid clogging of the two atomizing nozzles 14 in each group of spray assemblies.

[0034] The reset assembly includes a spring 27. A spring 27 is sleeved on the outside of the fixed rod 26 and near both ends. The two ends of the spring 27 are respectively fixedly connected to the outer wall of the sliding block 25 and the inner wall of the annular tube 2. The spring 27 can make the corresponding two half protective covers 24 tend to approach each other.

[0035] The support assembly includes a connecting disk 28, and the ends of the first rotating shaft 18 and the second rotating shaft 19 close to the central axis of the support frame 5 are respectively fixedly connected to the connecting disk 28, and the outer wall of the connecting disk 28 is fixedly connected to the top rod 29, and the end of the top rod 29 away from the connecting disk 28 is rotatably connected to the roller 30. The inner wall of the semi-protective cover 24 is fixedly connected to a rectangular block 31, and the inner wall of the rectangular block 31 is provided with a U-shaped groove 32. The roller 30 is rotatably connected in the U-shaped groove 32. It is worth mentioning that the three-way ball 10 is based on the position where the corresponding two atomizing nozzles 14 do not spray. During the process of three consecutive counterclockwise rotations, the atomizing nozzles 14 corresponding to the first rotating shaft 18 and the second rotating shaft 19 cannot spray, and only the first rotating shaft 18 There are four situations: the corresponding atomizing nozzle 14 can spray, only the atomizing nozzle 14 corresponding to the second rotating shaft 19 can spray, and the atomizing nozzle 14 corresponding to the first rotating shaft 18 and the second rotating shaft 19 can spray. Corresponding to the above four situations, the left and right lower parts of the transmission assembly and the support assembly correspond to the two groups of half protective covers 24 corresponding to the two atomizing nozzles 14, respectively, the two groups of half protective covers 24 are in a closed state, the two half protective covers 24 corresponding to the first rotating shaft 18 are separated and the two half protective covers 24 corresponding to the second rotating shaft 19 are closed, the two half protective covers 24 corresponding to the first rotating shaft 18 are closed and the two half protective covers 24 corresponding to the second rotating shaft 19 are separated, and the two groups of half protective covers 24 are in a separated state.

[0036] With the above-described structural design, when the drive motor 17 rotates the double-sided gear ring 15 via the corresponding first bevel gear 16, the double-sided gear ring 15 also drives the second bevel gear 20 to rotate. This in turn, drives the second transmission wheel 23 via the first rotating shaft 18. Subsequently, the first transmission wheel 21 rotates via the transmission belt 22, causing the second rotating shaft 19 to rotate simultaneously. The rotation of the first and second rotating shafts 18, 19 drives the corresponding connecting disk 28 to rotate, thereby moving the corresponding push rod 29. The movement of the push rod 29 causes the roller 30 on it to roll within the corresponding U-shaped groove 32, thereby enabling the rectangular block 31 to open or release the half protective cover 24. When the half protective cover 24 is opened, the corresponding spring 27 is deformed. When the half protective cover 24 is released, the elastic force of the spring 27 allows the two half protective covers 24 to move closer together.

[0037] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
