This dust removal module sets up the position that can be convenient for be in the roof of factory building or be close the roof in upper segment position, easy to assemble. Of course, the air duct can be disposed at other positions of the main air duct 100 in practical applications.
In some embodiments, the air intake structure comprises a secondary duct 103 connected to the primary air duct 100 and a suction nozzle 104 disposed at an end of the secondary duct 103, wherein a pipe diameter of the secondary duct 103 is smaller than that of the primary air duct 100. The secondary pipe 103 and the main air pipe 100, and the secondary pipe 103 and the suction nozzle 104 may be welded or fastened by screws or other known structures. Wherein the inner diameter of the secondary duct 103 is smaller than the inner diameter of the primary air duct 100, which ensures that the negative pressure generated by the blower 101 can be applied to each of the secondary duct 103 and the suction nozzle 104.
In some embodiments, the primary air duct 100 has a tube diameter of 90mm to 110mm, the secondary air duct 103 has a tube diameter of 9mm to 11mm, and both are seamless steel tubes. For example, the pipe diameter of the main air pipe 100 is 100mm, and the pipe diameter of the secondary pipe 103 is 10 mm; the pipe diameter of the main air pipe 100 is 110mm, and the pipe diameter of the secondary pipe 103 is 9 mm; for example, the pipe diameter of the main air pipe 100 is 92mm, and the pipe diameter of the secondary pipe 103 is 9 mm.
