[0014] (III) Beneficial Effects

[0015] The present invention provides a dust reduction device for municipal road construction, which has the following beneficial effects:

[0016] (I). For the dust reduction device for municipal road construction, by setting the spraying assembly, fine water mist is generated to directly settle the dust in the air. The blowing assembly uses the airflow field to disperse the water mist, making it spread more evenly, greatly increasing the contact probability between the water mist and the dust. According to the principle of the mixing and diffusion of air and water mist, this synergistic effect significantly improves the dust reduction efficiency, can effectively reduce the dust concentration in the construction area, create a fresher air environment for construction workers and surrounding residents, and reduce the harm of dust to the human respiratory system and so on.

[0017] (II). For the dust reduction device for municipal road construction, by setting the filtering component, the limit buckle plate is slidably connected to the mounting frame and the primary filter housing, which conforms to the maintainability principle in mechanical design. When it is necessary to replace the filter screen or clean the impurities in the primary filter housing, only by sliding the limit buckle plate can the primary filter housing and the mounting frame be conveniently taken out synchronously, simplifying the maintenance operation process, reducing the maintenance time and labor cost. Moreover, the filter screens arranged in a linear array are convenient for individually replacing the blocked or damaged filter screens, without the need to replace the filtering component as a whole, reducing the maintenance cost.

[0018] (III). For the dust reduction device for municipal road construction, by setting the filtering assembly, the waste water generated during the construction process can be introduced into the filtering component for purification treatment. After multiple filtrations by the primary filter housing and the filter screen, the purified water can be used for spraying dust reduction, realizing the recycling of water resources, reducing the dependence on external clean water sources, conforming to the environmental protection concept, and reducing the water resource consumption cost during the construction process.

[0019] (IV). For the dust reduction device for municipal road construction, by setting the fan assembly, during the operation process, not only does it accelerate the water flow speed in the water filtering housing according to the principle of fluid dynamics to improve the filtering efficiency, but also it provides a gas source for the blowing assembly. This design of one component with multiple uses makes full use of the energy conversion inside the device, reduces the investment in additional gas source devices and energy consumption, achieves the purpose of energy conservation, and reduces the operation cost of the device.

When water containing impurities such as dust and sand particles enters the water filtering shell 21, according to the mechanical filtering principle, the primary filtering shell 22 takes effect first, and its structural design enables larger particle impurities to be intercepted when the water flows through because their sizes are larger than the filter holes.

[0034] The pressurizing assembly 5 includes a stepping motor 54. A fixed bracket 55 is fixedly connected to the outer wall of the stepping motor 54. A water pump 51 is fixedly installed at the top of the fixed bracket 55 through a connecting bracket 52, and the outer wall of the connecting bracket 52 is fixedly installed with the outer wall of the water pump 51. The water inlet end of the water pump 51 is fixedly connected to a pump water pipe 56 through a water inlet branch pipe 53, and the outer wall of the water inlet branch pipe 53 is fixedly connected to the top of the pump water pipe 56.

The top of the water collecting shell 57 is fixedly connected to the bottom of the water collecting branch pipe 58. Under the action of the centrifugal force generated by the rotation of the impeller, water flows through the water collecting shell 57 and the water collecting branch pipe 58 into the pump water pipe 56, and then is sucked into the water pump 51 from the pump water pipe 56. After the water is pressurized by the water pump 51, the pressure is significantly increased and is transported to the spraying assembly 7 through a water guide pipe 75 to provide power support for efficient spraying and dust reduction. The outer wall of the pump water pipe 56 is fixedly connected to the inner wall of the fixed bracket 55, the outer wall of the fixed bracket 55 is fixedly connected to the inner wall of the fixed shell 1, the output end at the top of the stepping motor 54 is fixedly connected to the inner wall of the water pump 51, the bottom of the connecting bracket 52 is fixedly connected to the outer wall of the fixed bracket 55, the bottom of the fixed bracket 55 is fixedly connected to the top of the water collecting shell 57, and the water outlet end of the water pump 51 is fixedly connected to the bottom of the water guide pipe 75.

[0035] The water pump assembly 4 includes a fixing frame 44. A rotating shaft 41 is fixedly connected to the top of the fixing frame 44. The outer wall of the fixing frame 44 is fixedly connected to a water inlet pipe 42 through a limit buckle, and the water inlet pipes 42 are arranged in a circular array along the central axis of the fixing frame 44. The bottom of the fixing frame 44 is fixedly connected to a water inlet housing 43. When the fixing frame 44 rotates, it synchronously drives the water inlet housing 43 to rotate in the fixed housing 1, so as to introduce the water in the fixed housing 1 into the water inlet housing 43. A retaining net 45 is fixedly connected to the inner wall of the water inlet housing 43. The outer wall of the water inlet housing 43 is fixedly connected to a backwash housing 49. A retaining frame 46 is fixedly connected to the inner wall of the backwash housing 49. A water baffle 47 is fixedly connected to the inner wall of the backwash housing 49. A positioning plate 48 is fixedly connected to the inner wall of the backwash housing 49. When the fixing frame 44 rotates, it synchronously drives the water inlet housing 43 to rotate in the fixed housing 1, so as to introduce the water in the fixed housing 1 into the water inlet housing 43. The retaining net 45 in the water inlet housing 43 uses the screening principle to intercept larger-sized sundries and prevent them from entering the pipeline and causing blockage. And the water continuously enters the water inlet housing 43, so as to push the water into the water inlet pipe 42 and send it into the return water housing through the water inlet pipe 42. The outer wall of the water baffle 47 is in contact with the outer wall of the retaining frame 46. The outer wall of the water baffle 47 is in contact with the outer wall of the positioning plate 48. The outer wall of the water inlet housing 43 is fixedly connected to the bottom of the water inlet pipe 42. The top of the water inlet pipe 42 is fixedly connected to the inner wall of the bottom of the water collecting housing 57. The top of the rotating shaft 41 is fixedly connected to the output end of the bottom of the stepper motor 54. When it is necessary to clean the retaining net 45 in the water inlet housing 43, only need to reverse the rotation of the stepper motor 54, so that the water flow in the fixed housing 1 enters the water inlet housing 43 from the backwash housing 49. When the water flow passes through the water baffle 47, under the impact of the water flow, the water baffle 47 is driven to move towards the retaining frame 46 and is blocked by the retaining frame 46. The water flow can flow into the water inlet housing 43 from the retaining frame 46 and wash the retaining net 45. And when the stepper motor 54 does not rotate in the reverse direction, the water flow enters the backwash housing 49 from the water inlet housing 43 and impacts on the water baffle 47, forcing the water baffle 47 to move towards the positioning plate 48 and being blocked by the positioning plate 48, so as to block the water flow from flowing out of the backwash housing 49.

[0036] The core load-bearing structure of the dust reduction equipment is the fixed housing 1, which provides support and installation foundation for each component. The filtering component 2 is firmly connected to the top of the fixed housing 1 by welding to ensure the structural stability and prevent loosening during the operation and movement of the equipment, which may affect the filtering and overall functions. The integrated component 3 is installed on the inner wall of the fixed housing 1 by welding to build the internal core working system.

[0037] At the construction site of the municipal road, first, according to the scope and terrain of the construction area, determine the placement position of the dust reduction equipment. Move the fixed shell 1 with rollers to a suitable location to ensure that the equipment is placed stably and will not tip over due to uneven ground. Then, check whether the connections of all components of the equipment are firm, especially the connection of the filtering component 2 to the top of the fixed shell 1 and the installation of the integrated component 3 on the inner wall of the fixed shell 1, to ensure that no component loosening occurs during the operation of the equipment.

[0038] Subsequently, the wastewater generated during the construction process can be poured into the filtering component 2. The filtering component 2 has a water filtering shell 21 as the main body and contains a primary filter shell 22. When water containing impurities such as dust and sand particles enters the water filtering shell 21, according to the mechanical filtration principle, the primary filter shell 22 first plays a role. Its structural design makes larger particle impurities be intercepted because their sizes are larger than the filter holes and cannot continue to move forward with the water flow, achieving preliminary solid-liquid separation and effectively reducing the burden of subsequent fine filtration.

[0039] The filter screens 25 arranged in a linear array in the installation frame 23 undertake the heavy responsibility of fine filtration. According to the screening filtration principle, when water flows through the filter screens 25, impurities with sizes smaller than the pore diameter of the filter screens 25 are further blocked. The sliding connection design of the limit retaining plate 24 with the installation frame 23 and the primary filter shell 22 not only ensures the stable installation of the installation frame 23 but also facilitates the convenient replacement when the filter screens 25 are blocked or damaged, meeting the maintainability principle in mechanical design. Thus, when it is necessary to replace the filter screens 25 and pour out the impurities on the primary filter shell 22, only need to slide the limit retaining plate 24 so that the limit retaining plate 24 is inserted into the inner wall of the installation frame 23, and then grasp the primary filter shell 22 to synchronously take out the installation frame 23, thereby facilitating the replacement of the filter screens 25 in the installation frame 23.

[0040] The fan assembly 26 is fixed in the fixed shell 1 through the connecting plate 27. Its operation generates air flow. According to the principle of fluid dynamics, it accelerates the water flow speed in the water filtering shell 21, prevents impurities from accumulating locally, improves the filtration efficiency, and ensures that the water quality meets the subsequent spraying requirements. At the same time, the upper baffle 29 and the lower baffle 28 are used to block the water flow, thereby preventing the water flow from submerging the fan assembly 26 and causing immersion damage to the fan assembly 26. And it should be noted that the water in the fixed shell 1 should not exceed the height of the fan assembly 26.

[0041] The stepping motor 54 in the pressurizing component 5 is fixed to the fixed bracket 55, following the principle of motor installation and fixation. When the stepping motor 54 is powered on and operates, it is transmitted to the water pump 51 through the motor shaft, driving the impeller of the water pump 51 to rotate at a high speed. The water pump 51 is firmly connected to the fixed bracket 55 through the connecting bracket 52 to ensure the stability during the power transmission process.

[0042] The fixing bracket 44 of the water pump assembly 4 is connected to the output end at the bottom of the stepping motor 54 through a rotating shaft 41. Further, the fixing bracket 44 is driven to rotate by the motor. When the fixing bracket 44 rotates, the water inlet housing 43 is synchronously driven to rotate in the fixed housing 1, so as to introduce the water in the fixed housing 1 into the water inlet housing 43. The retaining net 45 in the water inlet housing 43 uses the screening principle to intercept larger-sized sundries and prevent them from entering the pipeline and causing blockage. And the water inlet housing 43 continuously admits water, thus pushing the water into the water inlet pipe 42 and sending it into the return water housing through the water inlet pipe 42.

[0043] The water inlet end of the water pump 51 is connected to the pump water pipe 56 through a water inlet branch pipe 53. Under the action of the centrifugal force generated by the rotation of the impeller, the water flow enters the pump water pipe 56 through the water collecting housing 57 and the water collecting branch pipe 58, and then is sucked into the water pump 51 from the pump water pipe 56. The water flow after being pressurized by the water pump 51 has a significantly increased pressure and is transported to the spraying assembly 7 through the guide pipe 75 to provide power support for efficient spraying and dust reduction.

[0044] The inner wall of the spraying arc plate 71 of the spraying assembly 7 is fixedly connected with a water pipe 73. The pressurized water flow enters the connecting water pipe 73 along the guide pipe 75. Under the action of the pressure, the water flow sprays out from the spray nozzles on the spraying arc plate 71 to form a fine water mist. The rotating ring 76 on the outer wall of the connecting water pipe 73 is rotatably connected to the inner wall of the top of the fixed housing 1, and the support frame 72 is connected to the rotating ring 76. Using the mechanical rotation principle, the spraying arc plate 71 can rotate around the rotating ring 76 as the axis to expand the water mist coverage area and improve the comprehensiveness of dust reduction.

[0045] The blowing arc plate 61 of the blowing assembly 6 is magnetically adsorbed to the spraying arc plate 71 through a permanent magnet, and the two cooperate. The blowing branch pipes 62 and the spray pipes 64 sleeved on both sides of the blowing arc plate 61 distribute the gas evenly on the outer wall of the blowing arc plate 61 through the linearly arrayed jet grooves 63 to form an air flow field. This air flow field acts on the water mist generated by the spraying assembly 7. According to the principle of air and water mist mixing and diffusion, the water mist is dispersed to make it more evenly dispersed into the air, increasing the contact probability between the water mist and the dust, thereby greatly improving the dust reduction effect. The air outlet pipe 74 on the inner wall of the connecting water pipe 73 is connected to the bottom of the spray pipe 64 for transporting specific gas to further enhance the air flow effect of the blowing assembly 6 and optimize the dust reduction performance. And the air source of the blowing assembly 6 comes from the wind power of the fan assembly 26. During the continuous rotation of the fan assembly 26, it not only accelerates the filtration of the filtration assembly, but also the blown air enters the fixed housing 1 and enters the spray pipe 64 through the air outlet pipe 74, and then continuously provides gas for the blowing assembly 6.
