Description

Technical Field

[0001] The invention relates to the technical field of dust removal, in particular to a special dust removal device for indoor decoration construction. Background Art

[0002] Decoration construction is a common project in residents' lives. However, the dust generated during indoor decoration construction often affects the indoor air quality, which not only affects the health of construction workers, but also may pose a threat to the health of residents. Therefore, it is very important to scientifically control the dust during construction. Before carrying out indoor decoration construction, the construction unit should conduct a comprehensive cleaning and sealing of the construction site, including cleaning up debris and garbage in the construction area, ensuring that the construction site is clean and tidy, closing the doors, windows and vents in the construction area, reducing indoor and outdoor air exchange, and reducing the possibility of dust dispersion. Special dust removal devices for indoor decoration construction have important applications in decoration construction.

[0003] As disclosed in the authorization announcement number CN213433558U, a dust removal device for indoor decoration construction includes a dust removal box, movable wheels are fixedly installed around the bottom of the dust removal box, a push rod is fixedly installed at the bottom of the right side of the dust removal box, an isolation plate is fixedly installed in the middle of the inner cavity of the dust removal box, two fans are fixedly installed on the left and right sides of the top of the isolation plate, and the air outlets of the two fans are fixedly installed at one end and extend to the dust exhaust pipe that passes through the outside of the isolation plate. Although it is realized that when in use, the motor and two fans are started and the dust removal box is pushed to move around the room via the push rod, the two fans transfer the dust to the clean water via the dust guide pipe and the dust collecting hood via the dust exhaust pipe, and the output shaft of the motor will drive the stirring blade to rotate via the transmission shaft and the rotating block, so that the dust can be quickly mixed with the clean water to avoid dust. However, it does not solve the problem that the existing dust removal devices of this type are generally not conducive to rapid mixed dust removal with adjustable flow rate when in use, and are not convenient for interlocking transmission to adjust the flow rate for uniform mixed dust removal. If the flow rate is too fast, the dust is easy to overflow directly without mixing the liquid, which is not convenient for cleaning the collected dust and not convenient for rapid suction and dust removal at the dust position with adjustable angle, which greatly affects the efficiency and effect of dust removal.
