Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression spray devices, specifically a multi-directional adjustable dust suppression spray device for construction sites. Background Technology

[0002] Dust suppression spray equipment is a device used to reduce the concentration of dust in the air, typically used in environments such as construction sites. Its working principle involves a water pump delivering water or other liquids to the air outlet of a fan, where wind propels the water into the air to form a water mist. This mist adsorbs dust particles in the air onto the surface of the water droplets, thus achieving dust suppression. A search reveals that Chinese patent publication number CN222816514U discloses a construction dust suppression spray device, including a frame and a fan. The fan is located on the upper right side of the frame, and a water tank is located inside the frame. Multiple nozzles are evenly spaced on the inner wall of the fan's right-side air outlet. These nozzles spray water to suppress dust. An arc-shaped collection trough is located on the lower right side of the fan, and this trough is connected and fixed to the fan via multiple fixing rods.

[0003] While the above-mentioned technical solution can recycle dripping water through the arc-shaped collection trough and telescopic hose, thus reducing water waste, the recycled water may be mixed with impurities such as dust and sand during use, leading to nozzle blockage or water pump wear. Furthermore, as the spray angle increases, some water is prone to flow back into the fan, thereby affecting the normal operation of the fan. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example:

[0021] like Figures 1 to 4 As shown, a multi-directional adjustable dust suppression spray device for construction sites includes a vehicle body 1 for mobile devices, a water tank 2 installed on the top of the vehicle body 1, a multi-angle blower mechanism 3 installed on the top of the water tank 2, a spraying mechanism 4 installed at one end of the multi-angle blower mechanism 3, and a filter return mechanism 5 installed on the outer surface of the spraying mechanism 4.

[0022] The multi-angle blower mechanism 3 and spray mechanism 4 not only enable multi-directional adjustment of dust suppression spray to improve dust suppression effect, but also prevent some water from flowing into the multi-angle blower mechanism 3, thus improving the collection effect and safety. The filter return mechanism 5 can filter and return the dripping water, which not only avoids wasting water resources, but also filters the water to avoid affecting the normal operation of the spray mechanism 4, thereby improving its service life.

[0023] like Figure 1As shown, the multi-angle blower mechanism 3 includes a base 31 fixedly installed on the top of the water tank 2. A motor is embedded in the center of the base 31. The output shaft of the motor is fixedly connected to a turntable 32. A bracket 33 is fixedly installed on one side of the top of the turntable 32. A fan 34 is rotatably connected to the top of the bracket 33. An electric push rod 35 is rotatably connected between the top of the turntable 32 and the bottom of the fan 34.

[0024] The rotation of the motor can drive the turntable 32 and the fan 34 to rotate horizontally, and the operation of the electric push rod 35 can drive the fan 34 to rotate up and down, thereby changing the blowing angle. In conjunction with the spray mechanism 4, it can achieve multi-directional adjustable dust suppression spray effect at the construction site.

[0025] like Figures 1 to 3 As shown, the spraying mechanism 4 includes an air outlet hood 41 fixedly connected to the air outlet end of the blower 34. An annular pipe 42 is fixedly connected inside the air outlet hood 41. Multiple atomizing nozzles 43 are fixedly installed on the outer surface of the annular pipe 42 in sequence. A water pump 44 is fixedly installed on the top of the water storage tank 2. The input end of the water pump 44 is connected to the inside of the water storage tank 2. A delivery hose 45 is fixedly connected between the output end of the water pump 44 and the annular pipe 42.

[0026] The operation of water pump 44 can draw water from water storage tank 2 and spray it out through atomizing nozzle 43 for easy dust suppression.

[0027] The inner wall of the air outlet shroud 41 is provided with an annular collection groove 46, and the bottom of the annular collection groove 46 is provided with a collection hole 47 that communicates with the inside of the collection shroud 51.

[0028] During use, some water that cannot be atomized will adhere to the inner wall of the air outlet cover 41 and gather into a stream, then flow into the annular collection groove 46, and finally flow into the collection cover 51 in the filter return mechanism 5 through the collection hole 47. This can prevent some water from flowing into the multi-angle blower mechanism 3, and can improve the collection effect and safety.

[0029] like Figures 1 to 4 As shown, the filtration and return mechanism 5 includes a collection cover 51 fixedly installed on the outer surface of the spray mechanism 4. A return pipe 52 is fixedly connected to the bottom of the collection cover 51, and a filter box 53 is fixedly connected to the bottom end of the return pipe 52. A return hose 54 is fixedly connected to the bottom end of the filter box 53, and one end of the return hose 54 is connected to the interior of the water storage tank 2. A first filter screen 55 is fixedly connected at an angle inside the filter box 53. A second filter screen 56 is slidably connected to one side of the filter box 53, located below the first filter screen 55. A discharge port 57 that cooperates with the first filter screen 55 is opened on one side of the filter box 53.

[0030] Some water drips from the bottom of the air outlet hood 41 due to the air force of the fan 34 and falls into the collection hood 51. Then it flows through the return pipe 52 into the filter box 53 and is filtered by the first filter screen 55 and the second filter screen 56 in sequence. Finally, it flows back to the water storage tank 2 through the return hose 54 for reuse. This not only avoids wasting water resources, but also filters the water to avoid affecting the normal operation of the spray mechanism 4, thereby improving its service life.

[0031] In this technical solution, the first filter screen 55 can filter large particulate impurities and discharge them through the discharge port 57. The second filter screen 56 is used to filter small particulate impurities. The second filter screen 56 is embedded and slidably connected in the filter box 53, which is convenient for subsequent removal, cleaning and replacement.

[0032] like Figure 1 As shown, a handrail 6 is fixedly installed on one side of the vehicle body 1, which facilitates the pushing of the device.

[0033] A controller 7 is installed on the top of the water storage tank 2. In this technical solution, the multi-angle blower mechanism 3 and the spray mechanism 4 are both connected to the controller 7 through wires. The controller 7 facilitates the control of the operation of the multi-angle blower mechanism 3 and the spray mechanism 4. Controlling through the controller 7 is a common technical means used by those skilled in the art and belongs to the prior art.

[0034] Working principle: When in use, the device can be pushed to the construction site where dust suppression is required by the handle 6 and the moving wheels at the bottom of the vehicle body 1. Then, the multi-angle blower mechanism 3 and the spray mechanism 4 are activated according to the specific dust suppression location. The water pump 44 runs to draw water from the water tank 2 and spray it out through the atomizing nozzle 43 for easy dust suppression. The motor rotation can drive the turntable 32 and the blower 34 to rotate horizontally. The electric push rod 35 runs to drive the blower 34 to rotate up and down, thereby changing the blowing angle. In conjunction with the spray mechanism 4, the dust suppression spray effect can be adjusted in multiple directions at the construction site.

[0035] During use, some water that cannot be atomized will adhere to the inner wall of the air outlet hood 41 and collect into a stream, then flow into the annular collection groove 46, and finally flow into the collection cover 51 in the filter return mechanism 5 through the collection hole 47. This can prevent some water from flowing into the multi-angle blower mechanism 3, and improve the collection effect and safety. Some water will drip from the bottom of the air outlet hood 41 due to the wind force of the blower 34 and fall into the collection cover 51, then flow into the filter box 53 through the return pipe 52, and be filtered by the first filter screen 55 and the second filter screen 56 in sequence. Finally, it flows back to the water storage tank 2 through the return hose 54 for reuse. This not only avoids wasting water resources, but also filters the water, preventing it from affecting the normal operation of the spray mechanism 4, thereby improving its service life.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
