Description

Technical Field

[0001] This utility model relates to the field of construction environmental protection technology, and in particular to a dust absorption and filtration device for construction projects in ecologically fragile areas. Background Technology

[0002] Dust absorption and filtration devices are high-efficiency air purifiers designed for industrial waste gas, fumes, and dust. Their structure comprises a complete air purification system consisting of a dust extraction duct, a high-efficiency filter, an activated carbon filter, a dedicated dust extraction fan, and a touch-screen microcomputer controller. In engineering construction, dust absorption and filtration devices are typically placed directly near areas generating significant dust. This is not a problem for projects with ordinary environmental requirements. However, in ecologically fragile areas, strict requirements are placed on the amount of dust that can overflow the construction area. Simply using a limited number of dust absorption and filtration devices directly at the dust generation point presents several problems:

[0003] 1. It cannot prevent dust from overflowing.

[0004] 2. It cannot be guaranteed that the dust will not be carried away from the construction site by the construction workers.

[0005] Therefore, it is necessary to develop a dust absorption and filtration device for engineering construction in ecologically fragile areas to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to design a dust absorption and filtration device for engineering construction in ecologically fragile areas in order to solve the above problems.

[0007] This utility model achieves the above objectives through the following technical solutions:

[0008] A dust absorption and filtration device for construction projects in ecologically fragile areas includes:

[0009] First air curtain machine;

[0010] Rear shielding block; the first air curtain unit is installed on top of the rear shielding block;

[0011] First side blocking block;

[0012] Second side blocking block; First side blocking block and second side blocking block are parallel;

[0013] Negative pressure vacuum cleaner; the negative pressure vacuum cleaner is parallel to the first air curtain machine; the first air curtain machine, the negative pressure vacuum cleaner, the first side shielding block, and the second side shielding block form a cuboid, and the construction work is located within the cuboid; the first air curtain machine is installed at a higher height than the negative pressure vacuum cleaner, and the top air curtain generated by the first air curtain machine is tilted downwards, fully covering the top of the cuboid, and the lower end of the top air curtain is equal to or lower than the top of the suction port of the negative pressure vacuum cleaner;

[0014] The second air curtain machine is installed on the first side shielding block, and the side air curtain generated by the second air curtain machine covers the inlet and outlet.

All construction-related materials are placed within this space to prevent dust from overflowing. In addition, by opening an entrance and exit on the first side shielding block and covering the entrance and exit with a side air curtain formed by a second air curtain machine, construction personnel and equipment can reduce the amount of dust carried away when leaving the site, thereby reducing pollution to the ecologically fragile area.

[0040] The dust absorption and filtration device also includes a fan 18 and a mobile trolley 22. The fan 18 is installed on the top of the mobile trolley 22.

The suction port of the negative pressure vacuum cleaner 2 is installed in the space enclosed by the third column 8, the fourth column 9, and the second crossbeam 10.

[0044] like Figure 4 As shown, in some embodiments, the first side shielding block 13 includes a first inclined beam 11, a connecting plate 19, and a first transparent windproof curtain 20. The two ends of the first inclined beam 11 are respectively installed on the top of the first column 4 and the third column 8.

The first transparent windproof curtain 20 fully covers the space enclosed by the first inclined beam 11, the first column 4, and the third column 8, excluding the connecting plate 19, the second air curtain machine 3, and the side air curtain 16.

[0045] like Figure 1 As shown, in some embodiments, the second side shielding block 14 includes a second inclined beam 12 and a first transparent windproof curtain 20. The two ends of the second inclined beam 12 are respectively installed on the top of the second column 5 and the fourth column 9. The first transparent windproof curtain 20 is fully covered in the space enclosed by the second inclined beam 12, the second column 5 and the fourth column 9.

[0046] It should be noted that in this application, the first column 4 and the second column 5 have the same length, the third column 8 and the fourth column 9 have the same length, the first inclined beam 11 and the second inclined beam 12 have the same length, and the first crossbeam 6 and the second crossbeam 10 have the same length.

[0047] Working principle:

[0048] First, determine the scope of the construction project. Then, expand the scope appropriately and install the first column 4, second column 5, third column 8, and fourth column 9 around the construction site. Next, erect the first horizontal beam 6 above the first column 4 and second column 5, and the second horizontal beam 10 above the third column 8 and fourth column 9. Then, erect the first diagonal beam 11 above the first column 4 and third column 8, and the second diagonal beam 12 above the second column 5 and fourth column 9. Finally, install the first air curtain machine 1 above the first horizontal beam 6, and the negative pressure vacuum cleaner 2 below the second horizontal beam 10. Adjust the first air curtain machine 1 so that the end of the top air curtain 15 of the first air curtain machine 1 is equal to or lower than the negative pressure vacuum cleaner. Install the dust inlet at the top of the 2; then install the connecting plate 19 below the first inclined beam 11, and install the second air curtain machine 3 below the connecting plate 19. Adjust the second air curtain machine 3 so that the side air curtain 16 of the second air curtain machine 3 fully covers the inlet and outlet; then install two first transparent windproof curtains 20 and one second transparent windproof curtain 21 respectively. The two first transparent windproof curtains 20 are installed below the first inclined beam 11 and the second inclined beam 12 respectively, and the second transparent windproof curtain 21 is installed below the first crossbeam 6; finally, lay the guide rail 17 along the inner side wall of the rear shield block 7, install the fan 18 on the moving trolley 22, and place the moving trolley 22 in the straight groove in the guide rail 17. During construction, the first air curtain 1 and the second air curtain 3 must be kept running. Dust generated during construction is drawn in by the top air curtain 15 and absorbed by the negative pressure vacuum cleaner 2. The airflow within the enclosed space is primarily from back to front, ensuring that most of the dust is initially absorbed by the negative pressure vacuum cleaner 2. At the end of the day's work, after all workers have left, the blower 18 can be turned on, and the trolley 22 can be slowly moved back and forth within the guide rail 17. The blower 18 will lift dust that has fallen onto the ground or equipment and blow it towards the negative pressure vacuum cleaner 2, preventing dust accumulation that would be difficult to remove later and avoiding the need for extensive manual labor for dust extraction. Once most of the dust has been removed, the blower 18, the first air curtain 1, and the second air curtain 3 can be turned off.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
