Description

Technical Field

[0001] This utility model relates to the field of dust control technology, specifically a dust control facility for construction sites. Background Technology

[0002] In construction activities, especially at construction sites, a large amount of dust is usually generated, which is extremely harmful to the working environment of workers and their health. Therefore, dust control equipment is usually needed to deal with it.

[0003] According to CN219663229U, a dust control device for construction sites is disclosed. This technology includes a handcart, a water collection tank fixedly connected to the top of the handcart, a filter box fixedly connected to the other side of the top end of the water collection tank, a protective cover on one side of the width of the water collection tank, an exhaust fan fixedly connected inside the protective cover, and an aeration pipe fixedly connected to one side of the protective cover. The device offers the following technical benefits: "By starting the exhaust fan, air is drawn in, and dust is drawn into the aeration pipe and then sprayed out through the aeration nozzles. This allows the dust-laden air to aerate and fully contact the water, removing the dust. While the pressurized pump draws water from the water collection tank, the wastewater enters the filter box through the lower water pipe. After being filtered by the dust removal filter element, it is sprayed out from the spray nozzles under the action of the pressurized pump, effectively spraying water to remove dust, thus making full use of water resources and improving the dust removal effect of the dust control device for construction sites."

[0004] Existing dust control facilities at construction sites mostly use a single linear nozzle layout, resulting in limited water mist coverage and dead zones, making it difficult to fully cover dust spreading in the space. At the same time, the lack of airflow propulsion design causes water mist particles to settle quickly under gravity, failing to effectively reach distant dust accumulation areas. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dust control facility for construction sites. Through the circumferential layout of the arc-shaped pipes and the circumferential distribution of the atomizing nozzles, the water mist spray range expands in a ring shape. Combined with the airflow boosting effect of the fan blades, this significantly improves the dust control facility's efficiency in capturing and reducing the settling speed of airborne dust.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust control facility for construction sites, comprising a handcart, wherein the handcart is equipped with a dust control mechanism for dust control, the dust control mechanism comprising:

[0007] The spray assembly includes a frame fixed on a handcart, a circular plate fixed to the front end of the frame, an arc-shaped tube fixed to the front end of the circular plate by a fixing bracket, a number of atomizing nozzles distributed in a circle installed at the front end of the arc-shaped tube, a cylinder seat fixed to the front end of the circular plate, and a fan blade installed inside the front end of the cylinder seat.

[0008] Water supply components, mounted on the rack, are used for water delivery;

[0009] The drive unit is mounted on the frame and is used to provide power.

[0010] Preferably, the water supply assembly includes a water tank installed at the upper end of the frame, a water pump installed at the lower end of the frame, an inlet pipe connected between the lower end of the water tank and the water pump inlet, an outlet pipe connected between the arc-shaped pipe and the water pump outlet, and a water filling pipe connected to the upper end of the water tank.

[0011] Preferably, the driving device includes a shaft rotatably mounted on the front end of the frame via a bearing seat, with fan blades fixed to the front end of the shaft, a first driven pulley fixed to the outer wall of the rear end of the shaft, a motor installed at the lower end inside the frame, a first driving pulley fixed to the output end of the motor, and a first belt installed between the first driving pulley and the first driven pulley.

[0012] Preferably, the drive device further includes a second driving pulley fixed to the output end of the motor, a second driven pulley fixed to the input end of the water pump, and a second belt installed between the second driven pulley and the second driving pulley.

[0013] Preferably, the water supply assembly further includes a filter installed on the inlet pipe.

[0014] Preferably, the water supply assembly further includes a transparent tube connecting the upper and lower ends of the left side of the water tank.

[0015] Beneficial effects

[0016] This utility model provides a dust control facility for construction sites. Compared with the prior art, it has the following advantages:

[0017] 1. The circular plate serves as the front-end mounting base. Its front end is fixed with an arc-shaped tube in a circumferential manner via a fixing frame, so that several atomizing nozzles at the front end of the arc-shaped tube are evenly distributed along the circumference to form a three-dimensional spray coverage surface. At the same time, a fan blade is installed inside the cylinder base fixed at the front end of the circular plate. When the fan blade rotates, it generates an axial airflow, which can effectively push and diffuse the fine water mist sprayed from the atomizing nozzles to a distance. Through the circumferential layout of the arc-shaped tube and the circumferential distribution of the atomizing nozzles, the water mist spray range expands in a ring shape. Combined with the airflow boosting effect of the fan blades, the dust control facility significantly improves the capture efficiency and settling speed of airborne dust.

[0018] 2. When the motor starts, its output power is transmitted to the first driven pulley via the first driving pulley and the first belt, driving the shaft to rotate and driving the fan blades to rotate at high speed. At the same time, when the motor starts, its output power is also transmitted to the second driven pulley via the second driving pulley and the second belt, driving the water pump to draw water from the water tank and deliver it to the arc-shaped pipe. By using a single machine with dual drive, not only is the installation space and mechanical weight required for additional power source configuration eliminated, reducing the overall manufacturing cost of the equipment, but also the coordinated work of the motor and the two sets of pulley transmission systems ensures precise synchronization of the airflow diffusion of the fan blades and the water mist spraying of the water pump.

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1 - Figure 4This utility model provides a technical solution: a dust control facility for construction sites, including a handcart 1, on which a dust control mechanism 2 is installed for dust control. The dust control mechanism 2 includes:

[0027] The spray assembly 21 includes a frame 211 fixed on a handcart 1, a circular plate 212 fixed at the front end of the frame 211, an arc-shaped tube 214 fixed at the front end of the circular plate 212 via a fixing bracket 213, a plurality of circumferentially distributed atomizing nozzles 215 installed at the front end of the arc-shaped tube 214, a cylinder seat 216 fixed at the front end of the circular plate 212, and a fan blade 217 installed inside the front end of the cylinder seat 216.

[0028] Water supply component 22 is mounted on frame 211 and is used for water supply;

[0029] Drive device 23 is mounted on frame 211 and is used for power supply.

[0030] In this embodiment, the circular plate 212 serves as the front-end mounting base. The arc-shaped tube 214 is fixed in a circumferential manner at its front end via the fixing frame 213, so that several atomizing nozzles 215 at the front end of the arc-shaped tube 214 are evenly distributed along the circumferential direction to form a three-dimensional spray coverage surface. At the same time, the front end of the cylinder base 216 fixed at the front end of the circular plate 212 is equipped with a fan blade 217. When the fan blade 217 rotates, it generates an axial airflow, which can effectively push and diffuse the fine water mist sprayed by the atomizing nozzles 215 to a distance. Through the circumferential layout of the arc-shaped tube 214 and the circumferential distribution of the atomizing nozzles 215, the water mist spray range expands in a ring shape. Combined with the airflow boosting effect of the fan blade 217, the dust treatment facility significantly improves the capture efficiency and settling speed of spatial dust.

[0031] Specifically, the water supply assembly 22 includes a water tank 221 installed at the upper end of the frame 211, a water pump 222 installed at the lower end of the frame 211, an inlet pipe 223 connected between the lower end of the water tank 221 and the inlet of the water pump 222, an outlet pipe 225 connected between the arc-shaped pipe 214 and the outlet of the water pump 222, and a water filling pipe 226 connected to the upper end of the water tank 221.

[0032] In this embodiment, the lower end of the water tank 221 is sealed to the inlet of the water pump 222 via the inlet pipe 223, ensuring the directional delivery of water from the water tank 221 to the water pump 222. The outlet of the water pump 222 is connected to the arc-shaped pipe 214 via the outlet pipe 225, so that the pressurized water can be accurately delivered to the atomizing nozzle 215 at the front end of the arc-shaped pipe 214 for atomized spraying.

[0033] Specifically, the drive device 23 includes a shaft 231 rotatably mounted on the front end of the frame 211 via a bearing seat, and a fan blade 217 fixed to the front end of the shaft 231. A first driven pulley 232 is fixed to the outer wall of the rear end of the shaft 231. A motor 233 is installed at the lower end inside the frame 211. A first driving pulley 234 is fixed to the output end of the motor 233. A first belt 235 is installed between the first driving pulley 234 and the first driven pulley 232.

[0034] In this embodiment, when the motor 233 starts, its output power is transmitted to the first driven pulley 232 via the first driving pulley 234 and the first belt 235, which drives the shaft 231 to rotate and drives the fan blade 217 to rotate at high speed.

[0035] Specifically, the drive device 23 also includes a second drive pulley 236 fixed at the output end of the motor 233, a second driven pulley 237 fixed at the input end of the water pump 222, and a second belt 238 installed between the second driven pulley 237 and the second drive pulley 236.

[0036] In this embodiment, when the motor 233 starts, its output power is transmitted to the second driven pulley 237 via the second driving pulley 236 and the second belt 238, driving the water pump 222 to pump water from the water tank 221 and deliver it to the arc-shaped pipe 214.

[0037] Specifically, the water supply assembly 22 also includes a filter 224 installed on the inlet pipe 223.

[0038] In this embodiment, the water source entering the water pump 222 is filtered and purified by the filter 224, which reduces the risk of clogging of the atomizing nozzle 215 and ensures the continuous and stable operation of the spray assembly 21.

[0039] Specifically, the water supply assembly 22 also includes a transparent tube 227 connected between the upper and lower ends of the left side of the water tank 221.

[0040] In this embodiment, the internal liquid level can be displayed in real time through the transparent tube 227, realizing intuitive and visual monitoring of the water level in the water tank 221, so that the operator can quickly judge the current water volume status without opening the water tank 221.

[0041] The working principle and usage process of this utility model are as follows: First, when the motor 233 starts, its output power is transmitted to the first driven pulley 232 through the first driving pulley 234 and the first belt 235, which drives the shaft 231 to rotate and drives the fan blade 217 to rotate at high speed; at the same time, when the motor 233 starts, its output power is also transmitted to the second driven pulley 237 through the second driving pulley 236 and the second belt 238, which drives the water pump 222 to draw water from the water tank 221 and deliver it to the arc-shaped pipe 214;

[0042] Then, the lower end of the water tank 221 is sealed to the inlet of the water pump 222 through the inlet pipe 223, ensuring the directional delivery of water from the water tank 221 to the water pump 222. The outlet of the water pump 222 is connected to the arc-shaped pipe 214 through the outlet pipe 225, so that the pressurized water can be accurately delivered to the atomizing nozzle 215 at the front end of the arc-shaped pipe 214 for atomization spraying. Through the surrounding layout of the arc-shaped pipe 214 and the circumferential distribution of the atomizing nozzle 215, the water mist spray range expands in a ring shape. Combined with the airflow boosting effect of the fan blade 217, the dust treatment facility significantly improves the capture efficiency and settling speed of airborne dust.
