[0029] The duct air supply device 100 provided in the embodiment of the utility model connects the air outlet interface pipe 180 to the temporary air duct (not shown) arranged at the construction site. The controller 130 starts the air supply fan 140 through the control panel 120. The air supply fan 140 filters and humidifies the polluted air in the working environment through the filter 150 and the humidifier 160, thereby improving the air quality in the working environment and avoiding the accumulation of dust and polluted airflow to cause harm to construction workers.

[0030] The duct air supply device 100 provided in the embodiment of the utility model performs static pressure noise reduction treatment on the filtered and humidified air through the muffler 170, thereby reducing the noise of the air flow output by the air outlet interface pipe 180, improving the environmental noise and enhancing the comfort of construction work.

[0031] The air duct air supply device 100 provided in the embodiment of the utility model can circulate, filter, humidify and reduce noise of the air in the working environment, thereby improving the construction safety of the working environment.

[0032] In order to facilitate handling and transportation, the duct air supply device 100 provided in the embodiment of the utility model has a shell 110 in the shape of a rectangular parallelepiped. In order to support the shell 110 and prevent it from being affected by the different height differences of the controller 130, the blower 140, the filter 150, the humidifier 160 and the muffler 170, six columns 190 are evenly distributed in the shell 110.

[0033] Please refer to Figure 1 In order to start and stop the blower 140 and control its operation, the duct air supply device 100 provided in the embodiment of the utility model, the control panel 120 can be a touch screen display, and of course can also be a button switch. Figure 1 Only the touch screen display is illustrated in the figure, and the functions of starting, stopping, running and adjusting the wind speed of the blower 140 during operation can be realized through the control panel 120. That is, the control switch and the display are integrated in the control panel 120. In order to reduce the volume, the controller 130 and the blower 140 are arranged in parallel.

[0034] In order to control the air blower 140, in the duct air supply device 100 provided by the embodiment of the utility model, the controller 130 may be a PLC (programmable logic controller) or a single chip microcomputer.

[0035] Please refer to Figure 3 In the duct air supply device 100 provided by the embodiment of the utility model, the air blower 140 includes a motor 141 and an impeller 142 connected thereto. The impeller 142 includes a housing and blades therein, and the motor 141 and the impeller 142 can be driven by a belt or a chain. Of course, the air blower 140 can also be other structures. In order to improve the air supply effect, the air blower 140 can be a centrifugal air blower. For example, the air blower 140 can be a blower. The air blower 140 uniformly collects and outputs the air to the filter 150, which can prevent the dust in the air from being blown away for the second time. At the same time, the filter 150 can also collect the particles in the air. A flow sensor connected to the controller 130 can be set on both sides of the filter 150. The flow sensor feeds back the filtered gas flow signal to the controller 130, so as to remind the filter 150 to be cleaned or replaced through the control panel 120 or the indicator light.

[0036] In order to replace the filter 150 to improve its filtering effect, the duct air supply device 100 provided by the embodiment of the utility model, the filter 150 can be a primary filter 150, but is not limited to other filters with filtering functions. The filter 150 can be replaced with a filter element or a filter screen.

[0037] Please refer to Figures 3 to 5 In order to humidify the filtered airflow, the duct air supply device 100 provided in the embodiment of the utility model comprises a humidifier 160 including a water collecting tank 161 located at the bottom of the shell 110 and arranged between the filter 150 and the muffler 170, a plurality of corrugated plates 162 arranged on the water collecting tank 161 at vertical intervals, a lifting pump 163 arranged in the water collecting tank 161 near the side of the filter 150, a water supply main pipe 164 connected to the lifting pump 163, and a plurality of water supply branch pipes 165 connected to the water supply main pipe 164 and located at the upper end of the corrugated plate 162, the water supply branch pipe 165 extending from one end of the corrugated plate 162 to the other end, and a water supply branch pipe 165 is arranged between two adjacent corrugated plates 162. Its working principle is: the lifting pump 163 outputs the water in the water collection tank 161 through the water supply main pipe 164 and the water supply branch pipe 165, and the water droplets flowing out of the water supply branch pipe 165 drop on the corrugated plate 164 and flow from top to bottom along the corrugated plate 164. The airflow between the corrugated plates 164 of the humidifier 160 drives the water droplets and water vapor on the corrugated plates 164 to make the output air flow moist, thereby achieving the purpose of humidification. Part of the water droplets on the corrugated plates 164 fall back into the water collection tank 161. The air flowing through the humidifier 160 increases the moisture content of the air supply, and the water mist on the corrugated plates 162 can further reduce the dust in the air. The corrugated plates 162 can be steel plates. At this time, the lifting pump 163 is connected to the controller 130, and the lifting pump 163 is controlled by the control panel 120, that is, the humidifier 160 can be controlled to open or close and adjust the pumping flow through the control panel 120. In order to improve the humidification effect, the water supply branch pipe 165 is provided with a plurality of small holes along its length direction, and the water in each water supply branch pipe 165 flows through the small holes on each corrugated plate 162, thereby increasing the wetted area of ​​the corrugated plate 162, and the airflow outputted through the filter 150 will take away the moisture on the corrugated plate 162 when flowing through the corrugated plate 162, thereby achieving a uniform humidification effect. In order to further improve the humidification effect, the end of the water supply branch pipe 165 can be a closed end, in which case, water droplets or water mist are output to the corrugated plate 162 only through the small holes on the water supply branch pipe 165, thereby improving the humidification effect on the corrugated plate 162 and preventing water from flowing into the muffler 170.

[0038] Please refer to Figures 3 to 5 In order to improve the stability of the water supply path, the duct air supply device 100 provided in the embodiment of the utility model has the water supply pipe 164 arranged in a rectangular ring along the end surface of the filter 150.

[0040] Please refer to Figure 3 In the duct air supply device 100 provided by the embodiment of the utility model, the muffler 170 can be a static pressure box. The static pressure box is a necessary accessory for the air supply system to reduce dynamic pressure, increase static pressure, stabilize airflow and reduce airflow vibration, which can make the air supply effect more ideal. The static pressure box is a device that can allow airflow to pass through and effectively prevent or weaken the propagation of sound energy outward. The muffler 170 has two square through-hole structures, and the humidified airflow passes through the two square through-hole structures of the muffler 170. The muffler 170 is assembled from sound-absorbing panels. Each square through-hole corresponds to two air outlet interface pipes 180. Of course, the square through-hole structure is not limited to two, and the air outlet interface pipes 180 are not limited to four. A dangerous gas detection sensor can be configured on the muffler 170 to monitor the content of dangerous substances in the air supply and feed back to the controller 130. The controller 130 can issue an alarm reminder on the control panel 120 when the dangerous gas reaches a critical value.
