Description

Technical Field

[0001] The invention relates to the technical field of spray dust reduction equipment, and in particular to a dust reduction device for construction and civil engineering. Background Art

[0002] In the field of construction and civil engineering, the dust problem generated during the construction process has always been a major problem that has troubled construction units and environmental protection departments. In cities, places near construction areas can obviously be found to have more traces of dust than other non-construction areas. Dust not only harms the health of workers on the construction site, but also pollutes the surrounding environment, affects air quality, and may even cause health problems such as respiratory diseases. Dust generated by construction has become a major obstacle to urban environmental protection.

[0003] Traditional dust reduction methods mainly include water sprinkling and covering. Water sprinkling is to sprinkle water on the construction area manually or mechanically to moisten and settle the dust particles. However, this method has problems such as waste of water resources, uneven water sprinkling, and limited dust reduction effect. Covering dust reduction is to reduce the generation of dust by laying dust-proof nets or dust-proof cloths and other coverings in the construction area. Although this method can reduce dust to a certain extent, the laying and removal of the covering requires a lot of manpower and material resources, and is easily affected by weather and human factors during use, and the dust reduction effect is unstable.

[0004] With the advancement of science and technology and the improvement of environmental awareness, people have begun to explore more efficient and environmentally friendly dust reduction methods. Spray dust reduction technology, as a new type of dust reduction method, has gradually been applied in the field of construction and civil engineering. Fog cannon is a common spray dust reduction device, but the defect of the fog cannon is that the spray range cannot be adjusted at the nozzle of the fog cannon, and the dust reduction area can only be adjusted by moving the nozzle of the fog cannon. Moreover, the water mist sprayed by the fog cannon is not entirely water mist, but also contains a large amount of water droplets. The dust reduction effect of this part of water droplets is average, but if the construction workers enter the construction nozzle of the fog cannon, their clothes will be quickly wetted by these water droplets. Therefore, in most cases, the fog cannon is only suitable for wetting the construction area before construction to reduce dust, and is not suitable for dust reduction during the construction process.

DETAILED DESCRIPTION

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0025] Examples, such as Figures 1 to 5 As shown, this embodiment includes a base 1, a shell component, a spray dust suppression device, and an adjustment component arranged between the base 1 and the spray dust suppression device, the adjustment component is used to adjust the spray dust suppression device in two directions of pitch and rotation, and the spray dust suppression device includes a blowing component and a spray component;

[0026] The outer shell component is composed of a cylindrical shell 2 and a partially conical conical shell 3, the cylindrical shell 2 and the conical shell 3 are detachably fixedly connected, a blowing assembly is fixedly arranged in the cylindrical shell 2, an air guide baffle ring 301 and an internal air guide shell 304 are arranged in the conical shell 3, the air guide baffle ring 301 is fixed to the inner wall of the conical shell 3, an air guide shell support frame 306 is fixed in the conical shell 3, the internal air guide shell 304 is slidably matched with the conical shell 3 through the air guide shell support frame 306, and the internal air guide shell 304 is slidably matched with the conical shell 3 through the air guide shell support frame 306. When the inner air guide shell 304 slides to the extreme state farthest from the cylindrical shell 2, one end of the inner air guide shell 304 close to the cylindrical shell 2 overlaps with the air guide baffle ring 301. In this state, the wind force generated from the cylindrical shell 2 will all pass through the inner air guide shell 304, and then be ejected from the nozzle of the inner air guide shell 304. In this state, the spray dust reduction equipment realizes long-distance and small-scale spray dust reduction. In this case, it is often used in large-scale open-air construction sites for wetting the construction area before construction, which plays a preventive effect.

[0027] In this embodiment, the inner wall of the internal air guide shell 304 is controlled to slide by the sliding hydraulic rod 13, the cylinder body of the sliding hydraulic rod 13 is fixed to the inner wall of the conical shell 3 through a cylinder body bracket, and the rod head of the telescopic rod of the sliding hydraulic rod 13 is fixedly connected to the inner wall of the internal air guide shell 304 through a rod head bracket. When the sliding hydraulic rod 13 is shortened to the shortest state, the annular gap between the internal air guide shell 304 and the air guide baffle ring 301 reaches the maximum.

[0028] Furthermore, the internal air guide shell 304 is a first air guide channel, and the internal air guide shell 304 and the conical shell 3 are between a second air guide channel. A spiral air guide plate 305 is provided in the second air guide channel, and the spiral air guide plate 305 is fixed to the inner wall of the conical shell 3. When the sliding hydraulic rod 13 is shortened to the shortest state, the wind generated by the blowing assembly will enter the second air guide channel from the annular gap, and will be ejected from the nozzle in a rotating and diffused state under the influence of the spiral air guide plate 305 in the second air guide channel, forming a diffused wind with a large range and a short distance.

[0029] In this embodiment, an annular water supply pipe 16 is fixed at the nozzle of the conical shell 3, and a plurality of nozzles 17 are evenly distributed in a ring on the annular water supply pipe 16. Each of the nozzles 17 is rotatably connected to the annular water supply pipe 16. The annular water supply pipe 16 and each of the nozzles 17 are connected via a water supply port 1601. The annular water supply pipe 16 is internally supplied with water through the water supply pipe 6. The water supplied from the water supply pipe 6 enters the annular water supply pipe 16 and is then sprayed out from each nozzle 17 for atomization.

[0030] When in use, when the sliding hydraulic rod 13 is in the maximum extension state, wind is blown out only from the first air guide channel, and the water mist sprayed from the nozzle 17 is sprayed in the form of a slender spray mist column under the strong wind of the first air guide channel, with a long spray distance. When the sliding hydraulic rod 13 is in the maximum shortening state, most of the water mist sprayed from the nozzle 17 is carried away by the diffused wind from the nozzle position of the second air guide channel, forming a large-scale dust reduction spray water mist.

[0031] Furthermore, in order to improve the use effect, the nozzle 17 is connected to the internal air guide shell 304 through an elastic pull rope 15, and the elastic pull rope 15 passes through the rope winding seat 14, and the rope winding seat 14 is fixed on the conical shell 3. A spray hole 3041 is opened on the internal air guide shell 304. When the sliding hydraulic rod 13 is in the maximum extension state, the nozzle 17 is aligned with the spray hole 3041, and the water mist sprayed from the nozzle 17 passes through the spray hole 3041 to reach the nozzle of the internal air guide shell 304. When the sliding hydraulic rod 13 is in the maximum shortening state, most of the water mist sprayed by the nozzle 17 is carried away by the diffused wind from the nozzle position of the second air guide channel, thereby forming diffused water mist, which is convenient for workers to reduce dust during construction.

[0032] At the same time, when the sliding hydraulic rod 13 is in the maximum shortened state, the spraying direction of each of the nozzles 17 can still intersect with the spraying direction of the first air guide channel, and most of the water mist sprayed by the nozzle 17 will be carried away by the wind in the second air guide channel at the nozzle position of the second air guide channel. However, the larger water droplets in the nozzle 17 that have not had time to be completely atomized or condensed together after atomization will enter the nozzle position of the first air guide channel again due to their large mass. The wind speed in the first air guide channel is greater and more concentrated, and these larger water droplets will be carried farther by the wind in the first air guide channel. It is only necessary to control the dust reduction area within the landing point range of the second air guide tube to prevent workers from getting their clothes wet by excessive water droplets during dust reduction.

[0033] In this embodiment, the blowing assembly includes a fan motor 11 and a fan 12. The fan motor 11 is fixed to the cylindrical shell 2. The fan 12 is fixed on the motor shaft of the fan motor 11. The high-speed rotation of the fan 12 is controlled by the fan motor 11 to provide wind power for the spray dust reduction equipment.

[0034] In this embodiment, the adjustment component includes a pitch control component and a swing control component, and the pitch control component includes a pitch hydraulic rod 4, one end of the cylinder body of the pitch hydraulic rod 4 is hinged to the seat body hinge seat 8, and the seat body hinge seat 8 is fixed on the pitch hydraulic rod 4, and the rod head of the telescopic rod of the pitch hydraulic rod 4 is hinged to the shell hinge seat 7, and the shell hinge seat 7 is fixed on the conical shell 3. Two coaxial fixed shafts are fixed on both sides of the cylindrical shell 2, and the two sides of the cylindrical shell 2 are rotatably connected to the top ends of two pillars 9 through the two fixed shafts, and the bottom end of each of the pillars 9 is fixed on the rotating base 5.

[0035] The swing control component includes the rotating base 5, the rotating control motor 18 and the motor fixing frame 10. The rotating base 5 is rotatably matched with the cylindrical shell 2. The motor fixing frame 10 is fixed in the cylindrical shell 2. The body of the rotating control motor 18 is fixed on the motor fixing frame 10. The motor shaft of the rotating control motor 18 is fixed to the center position of the rotating base 5. When spray dust reduction is performed, the rotation of the rotating control motor 18 is controlled by the control panel, and the rotating control motor 18 drives the rotating base 5 to rotate. The rotating base 5 then drives the entire spray dust reduction equipment to swing left and right. The pitch hydraulic rod 4 in the pitch control component controls the spray dust reduction equipment to pitch and swing around the top of the rotating control motor 18 by telescoping. The pitch control component and the swing control component are used to achieve all-round dust reduction coverage of a certain space around the spray dust reduction equipment.

[0036] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
