Abstract

The invention provides an energy-saving box type centrifugal fan. The energy-saving box type centrifugal fan comprises a mounting seat, an air inlet, open grooves, a dividing and combining mechanism,a buffering seat, a rotating motor, a driving wheel, a flat belt, a centrifugal mechanism, an air outlet, a box body, a bearing seat, a driven wheel and a positioning pin. Through arrangement of the centrifugal mechanism and the dividing and combining mechanism, the dividing and combining mechanism is pushed to drive a driven shaft to move leftwards to achieve sliding block type connection of a coupler. A driving shaft drives power to the driven shaft, and therefore a first centrifugal impeller and a second centrifugal impeller rotate at the same time, and the flow speed of air is improved. The two centrifugal impellers are adopted, so that the defect that the length of a box body behind the impellers influences the air sucking effect in the prior art is overcome. A rotating draught fan and the buffering seat is arranged, the buffering seat is additionally arranged at the bottom of the rotating motor, and therefore direct contact between the rotating motor and the box body is avoided,and vibration and noise during working are effectively reduced.

Description

technical field

[0001] The invention belongs to the technical field of centrifugal fans, in particular to an energy-saving box-type centrifugal fan. Background technique

[0002] The conventional centrifugal fan is to pressurize the air inhaled by the fan blade once and then send it out. The air supply volume depends on the size of the fan blade. The size of the fan blade is also equipped with a motor of corresponding power. Additional measures are carried out to further pressurize the airflow, and long-term application work consumes a lot of energy.

[0003] The Chinese patent publication number is CN 207728584U, and the name of the invention is a kind of energy-saving box-type centrifugal fan, which includes a box body, a fan body, a wind cover, a wind wheel, a fixed bracket, a fixed block, a contour block, an air outlet pipe, and an air outlet. The wind cover, the fan body installed with a fixed bracket is installed in the box, the right end of the fan body is provided w...
