Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection dust reduction, in particular to an environmental protection dust reduction device for building construction. Background Art

[0002] With the acceleration of urbanization and the continuous expansion of construction projects, the problem of dust generated at construction sites has become increasingly prominent. Dust not only seriously affects the quality of life of surrounding residents, but may also aggravate air pollution and cause serious damage to the environment. Therefore, dust control in construction has become an important issue to be solved. In view of this situation, the development and application of environmentally friendly dust reduction devices have become the key measures for dust control at construction sites. At present, there are some dust reduction devices for construction on the market, such as sprinkler trucks, enclosure spray systems, etc. These devices have achieved dust reduction effects to a certain extent, but still have some limitations. Therefore, corresponding improvements are needed. The announcement number CN112827283A discloses an environmentally friendly dust suppression device for construction, which relates to the technical field of construction. In order to solve the problem of water sprinkling and dust reduction during construction, the following solution is proposed, including a base, a dual-axis motor is fixedly connected to the top of the base, and a first rotating shaft is installed at the output ends of both sides of the dual-axis motor. A first active bevel gear is connected to the first rotating shaft by bolts, a first driven bevel gear is provided above the first active bevel gear, and the first active bevel gear is meshed with the first driven bevel gear bracket for transmission, a reciprocating screw is fixedly connected to the top of the first driven bevel gear, and a movable ring is threadedly sleeved on the reciprocating screw. The present invention not only allows the spray gun to move up and down through the combination of various structures, but also can blow the sprayed water so that it floats in the air for a longer time, thereby achieving a better dust reduction effect, and the device has a simple structure, low cost, and saves costs; The above-mentioned prior art uses a spray gun that moves up and down to spray water to reduce dust at a construction site. The spray range is limited by the fixed position and movement trajectory of the nozzle, and can usually only cover a specific area. This results in poor dust reduction effect in some areas, while other areas may be oversprayed. On the one hand, this reduces the dust reduction efficiency of the construction site, and on the other hand, it may cause a waste of water resources. Therefore, corresponding improvements are needed. The announcement number CN112458992A discloses an environmentally friendly spray dust suppression device for construction, including a base, a partition is provided on the top of the base, the top outer wall of the partition is connected to a uniformly distributed rotating rod through a bearing, and the bottom of the circumferential outer wall of the rotating rod is provided with a gear ring, the circumferential outer wall of the rotating rod is provided with staggered water outlet plates, and the bottom outer wall of the water outlet plate is provided with a distributed nozzle, and the bottom of the circumferential outer wall of the rotating rod is provided with a uniformly distributed arc plate. When the present invention is used, the nozzle sprays water mist to spray the air on the top of the partition, and the water mist contacts and settles with the dust in the air. At the same time, as the rotating rod rotates, the mesh plate contacts the water mist that contacts and adheres to the dust. The water mist condenses into water droplets on the mesh plate and slides down on the top outer wall of the water outlet plate and the inner arc surface of the arc plate. Finally, the sewage flows into the rotating rod through the perforation, preventing the sprayed sewage from flowing to the ground and causing the construction ground to be muddy. When the above-mentioned prior art is in use, the above-mentioned prior art uses the water outlet plate and the nozzle to spray water to reduce dust. However, in the process of spraying water to reduce dust, the direction and range are relatively single, and it is inconvenient to adjust the angle and range of the water spray, and it is impossible to effectively cover a wider area. This may cause some parts of the construction site to not receive sufficient dust reduction treatment, and the dust pollution problem still exists. Moreover, since the nozzle cannot spray water in all directions, the dust reduction effect of the construction site may be uneven. Some areas may waste water resources due to excessive water spraying, while other areas may have serious dust due to insufficient water spraying. Therefore, corresponding improvements are needed.

[0014] Compared with the existing technology, the beneficial effects of the present invention are: the environmentally friendly dust suppression device for construction can achieve multi-directional and multi-range spraying and dust reduction, and the dust suppression effect can be enhanced by adding dust suppressants, and has the effect of nozzle protection; An appropriate amount of dust suppression liquid and dust suppressant is injected into the dust suppression water tank through the liquid inlet pipe, and then the dust suppression liquid in the dust suppression water tank is extracted by a water pump in conjunction with a water guide pipe, and injected into the horizontal water spray pipe, and sprayed out from multiple sets of short pipes and dust suppression nozzles. The water particles are suspended in the air, forming fine water droplets, which physically collide with the suspended particles and wet the particles, increasing the weight and viscosity of the dust particles, making it easier for them to settle to the ground or be captured by the collector, thereby reducing the suspended concentration of the particles, effectively reducing dust, and improving the air quality of the construction environment.

The rotating motor drives the rotating shaft and the rotating chassis to rotate, thereby causing the dust suppression water tank to rotate synchronously and causing the guide column to rotate in the guide groove to limit and guide the rotation of the rotating chassis. This allows the horizontal water spray pipe, short pipe, and dust suppression nozzle to move in a circumferential direction, allowing dust suppression liquid to be sprayed in multiple areas at the construction site to ensure comprehensive and efficient dust suppression. During the rotation process, the double-sided bevel gear meshes with the driven gear, thereby rotating the stirring shaft and driving multiple sets of mixing rods to rotate to stir and mix the dust suppression clean water and dust suppressant inside the dust suppression water tank, ensuring that the dust suppressant is evenly distributed in the dust suppression liquid, avoiding the situation where the local concentration is too high or too low, and helping the dust suppressant to play a better role, thereby improving the dust suppression effect; After using the short tube and the dust reduction nozzle to spray water to reduce dust, manually turn the handle at one end of the worm to rotate the worm, and the worm and the worm wheel engage with each other, so that the worm wheel and the flip shaft can rotate, and the guard plate will flip up and down until it is flipped to one side of the short tube and the dust reduction nozzle to cover it, so as to achieve the effect of shielding and protection, and prevent external dust, particles and other impurities from falling onto the dust reduction nozzle, shield and protect the dust reduction nozzle, and achieve the anti-blocking effect to ensure the continuity of the use of the dust reduction nozzle.
