[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1:

[0022] Reference Figure 1-5 A dust collection device for civil engineering construction includes: a mobile vehicle 1 and a collection cover 2 mounted on the mobile vehicle 1. A filter cover 3 is fixedly connected inside the collection cover 2. The filter cover 3 is provided with an air collection port 303, a filter screen 302, and a dust collection box 301 from top to bottom. A transfer chamber 202 is provided between the collection cover 2 and the filter cover 3. An air extraction part is provided inside the air collection port 303. A rotating disk 4 is rotatably connected to the filter cover 3. A sealing disk 401 is fixedly connected to the rotating disk 4. The opening of the sealing disk 401 faces the filter screen 302. An air extraction cylinder 402 is provided on the sealing disk 401. An air extraction pump is provided inside the air extraction cylinder 402. The air extraction pump is used to extract the gas in the transfer chamber 202 and discharge it into the filter cover 3.

[0023] The exhaust unit includes a drive motor 304 installed in the air collection port 303. The output end of the drive motor 304 is fixedly connected to a drive shaft 3041. A fan blade 305 is installed on the drive shaft 3041. The drive shaft 3041 is connected to the rotating disk 4 through a gear set. The drive motor 304 is used to drive the drive shaft 3041 and the fan blade 305 to rotate, so as to pass the external dust-laden gas into the filter housing 3. After the speed is reduced by the gear set, the drive motor 304 provides power for the rotation of the rotating disk 4.

[0024] The gear set includes a speed-changing gear 5 located between the drive shaft 3041 and the rotating disk 4. The speed-changing gear 5 is rotatably connected to the filter housing 3, and the speed-changing gear 5 meshes with the rotating disk 4 and the drive shaft 3041 through gears.

[0025] The drive shaft 3041 transmits power to the rotating disk 4 through gear meshing and speed-changing gear 5. It should be noted that the speed-changing gear 5 can be set to multiple sets of speed-reducing gear ratios.

[0026] Furthermore, since the upper end of the gear shifting gear 5 faces the air collection port 303, in order to prevent dust from entering the meshing point between the gears, the gear shifting gear 5 is provided with three sets. A sealing plate is provided above the gear shifting gear 5. The sealing plate is rotatable with the rotating disk 4. The part of the rotating disk 4 located inside the filter cover 3 is provided with air vents 403.

[0027] The dust collection box 301 is slidably connected to the filter cover 3. The collection cover 2 is rotatably connected to the hinge door 201. The hinge door 201 cooperates with the dust collection box 301, and the filter cover 3 can be easily pulled out when the hinge door 201 is opened.

[0028] The mobile vehicle 1 is equipped with an activated carbon adsorption box 102. The transfer chamber 202 is connected to the activated carbon adsorption box 102 through the exhaust pipe 101. The activated carbon adsorption box 102 can adsorb odors in the air.

[0029] When using this device, the collection cover 2 and activated carbon adsorption box 102 can be moved to the construction site by the mobile vehicle 1. The drive motor 304 and the air pump are started. The air extraction unit will draw the dust-containing gas at the construction site into the filter cover 3 and pass it through the filter screen 302. At this time, the clean gas enters the activated carbon adsorption box 102 through the transfer chamber 202 and the exhaust pipe 101, is adsorbed and discharged, and the filtration and adsorption of dust in the gas is completed.

[0030] When the drive motor 304 is working, it will drive the rotating disk 4 to rotate around the filter screen 302, as shown in the figure. Figure 3 When the filter screen 302 is set into segments, when the sealing disc 401 on the rotating disk 4 covers the sealing disc 401 of a single segment, the air pump in the air pumping cylinder 402 will draw the filtered gas in the transfer chamber 202 and blow it toward the filter screen 302, causing the dust attached to the filter screen 302 to fall off, so that the dust falls under the action of gravity, preventing the single segment filter screen 302 from being blocked. Moreover, it can work continuously during this cleaning process, and the dust removal efficiency is better. At the same time, the air pump draws the filtered gas, which can prevent dust from entering the non-filtering surface of the filter screen 302 and ensure the quality of the discharged gas.

[0031] Furthermore, a scraper can be installed in the part of the rotating disk 4 located inside the filter housing 3 to improve the efficiency of dust falling off the filter screen 302.

[0032] This invention, through the rotatable sealing disc 401 and the segmented filter screen 302, can blow off and collect dust from the filter surface of the filter screen 302 during the dust collection process, thereby improving the efficiency of dust collection and the filtration effect, and enabling continuous use.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
