Furthermore, a gap is reserved in the filter layer; and a conveying belt and a driving mechanism for loading dust are arranged under the filtering layer, and the driving mechanism is in transmission connection with the conveying belt.
Further, two adjacent fans are assembled together through bolts.
Furthermore, the filter layer is arranged on one side surface of the fan wall body close to the dismantled building in a hanging and buckling mode.
Furthermore, the dust absorption wall also comprises a linkage controller, and the linkage controller is electrically connected with each fan; and the linkage controller is used for controlling the starting and the stopping of each fan and the power during working.
Furthermore, the dust absorption wall also comprises a fan phase regulator, wherein the fan phase regulator is respectively electrically connected with each fan, and the fan phase regulator enables the working power supply of each fan to form a phase difference so as to prevent the fan wall from forming resonance.
Compared with the prior art, the invention has the beneficial effects that:
the invention provides a dust absorption wall for a building demolition construction site, which comprises a fan wall body formed by stacking a plurality of fans, wherein a filter layer is arranged on the side surface of the front end of the fan wall body. The wall body of the fan can generate strong negative pressure to absorb dust into the dust absorption wall, and the filter layer in the dust absorption wall can play a role in collecting and filtering dust.
The protection net on the outer side surface of the filter layer can block splashed stone blocks, so that the filter layer and the fan are protected. The filter layer can block and filter fine dust (such as PM 2.5). Therefore, the air exhausted from the rear end of the device can meet the emission requirement, and the dust is prevented from influencing the surrounding environment and the physical health of people.
The fan wall body is formed by assembling a plurality of fans, and a single fan is small in size and convenient to transport and install.
