AI Technical Summary
In existing blowers, belt drive or gearbox speed-increasing design leads to large energy loss, fluctuating air volume requiring frequent adjustments, wear of transmission components causing vibration and misalignment, and a large amount of maintenance work.
It adopts a direct-drive structure, eliminating belts and gearboxes. It uses a permanent magnet motor coaxially connected to the fan blade module and reduces vibration through a multi-stage buffer support structure, including lateral and longitudinal buffer springs, rubber damping sleeves, etc., forming a two-stage buffer design.
It improves transmission efficiency, reduces maintenance workload, and lowers vibration and offset, making it suitable for space-constrained industrial scenarios and meeting the operating standards of precision equipment.

Abstract
Claims
1. A direct connection type industrial blower, comprising a frame and a blower body mounted on the top of the frame, the blower body comprising a blower shell and a fan blade module arranged in the blower shell, characterized in that: A motor module is installed on the top of the frame. The motor module includes a permanent magnet motor and a drive shaft installed on the drive end of the permanent magnet motor. The drive shaft is coaxially connected to the fan blade module. The fan housing is formed with an air inlet and an air outlet. The frame includes a first support frame and a second support frame. The second support frame is movably installed on the top of the first support frame. The top of the second support frame provides buffer support for the motor module and the fan body, respectively. The first support frame provides buffer support for the second support frame.
2. A direct connected industrial air blower as claimed in claim 1, wherein: The second support frame is provided with a first buffer support structure for the motor module. The first buffer support structure includes a first transverse support bar that is installed laterally on the second support frame. A plurality of first support columns arranged longitudinally are installed on the top of the first transverse support bar. The top of the first support columns is connected to the motor module.
3. A direct connected industrial air blower as claimed in claim 2, wherein: The first transverse support bar has transverse buffer columns formed at both ends, and the transverse buffer columns are fitted with first transverse buffer springs. The second support frame has transverse buffer holes for the transverse buffer columns to be inserted into.
4. A direct-drive industrial blower according to claim 1, characterized in that: The second support frame is provided with a second buffer support structure for the fan casing. The second buffer support structure includes a second transverse support bar that is installed laterally on the second support frame. The second transverse support bar is formed with a concave arc groove, and the curvature of the arc groove is adapted to the curvature of the fan casing.
5. A direct connected industrial air blower as claimed in claim 4, wherein: The arc-shaped groove is fitted with an arc-shaped plate, the top of which contacts and supports the fan casing. Multiple second longitudinal buffer springs are installed between the arc-shaped plate and the arc-shaped groove.
6. A direct connected industrial air blower as claimed in claim 1, wherein: A longitudinal buffer structure is provided between the first support frame and the second support frame. The longitudinal buffer structure includes a bottom connecting plate installed on the top of the first support frame and a top connecting plate installed on the bottom of the second support frame. A deformable compressible rubber is connected between the top connecting plate and the bottom connecting plate.
7. A direct connected industrial air blower as claimed in claim 6, wherein: The longitudinal buffer structure also includes a guide column installed on the top of the first support frame. The guide column is movably fitted with a movable sleeve. A stop ring is formed at the bottom of the movable sleeve. The second support frame is formed with a movable guide hole coaxially aligned with the movable sleeve. The stop ring supports the second support frame and is equipped with a rubber shock-absorbing ring.
8. A direct connected industrial air blower as claimed in claim 7, wherein: One of the guide columns is a lead screw, the movable sleeve is a guide screw sleeve, the bottom of the lead screw has a connecting shaft formed, and the bottom of the first support frame is provided with a bottom rolling bearing for installing the connecting shaft.
9. A direct connected industrial air blower as claimed in claim 8, wherein: The connecting shaft is formed with an insertion hole extending through the path, and an actuating post is detachably installed in the insertion hole.
