Problems solved by technology

[0002] Existing centrifugal fans are generally figure 1 In the form shown, the air inlet 6 is arranged on the volute 1 along the axial direction of the centrifugal fan, and the air outlet 7 is arranged tangentially to the volute 1 in a direction parallel to the front and rear disks of the volute. Therefore, For the existing centrifugal fans, the air inlet direction and the air outlet direction are vertical, but when the centrifugal fan is used on some specific equipment, this may cause inconvenience, for example, on a road sweeper, the air inlet duct Bot

Abstract

The invention discloses a centrifugal fan and a road sweeper. The centrifugal fan comprises a volute and an impeller arranged in the volute. The volute comprises an air inlet, an air outlet, a front disk, a rear disk and a connecting part, wherein the front disk and the rear disk are arranged in parallel; the connecting part is arranged between the front disk and the rear disk; and both the air inlet and the air outlet are formed on the connecting part along the parallel direction of the front disk and the rear disk. The road sweeper comprises the centrifugal fan. When the centrifugal fan disclosed by the invention is applied to a certain specific equipment, for example, when the centrifugal fan is used in the road sweeper of which an air inlet pipeline and an air outlet pipeline are both in parallel to the front disk and the rear disk of the volute, a reversing elbow does not need to be specially arranged to reverse airflow in the volute and the airflow can directly enter the volute from the air inlet through the air inlet pipeline without being reversed, and thus, the space structural layout is simplified, pressure loss is avoided and noise is also reduced.

Description

technical field [0001] The invention relates to the field of sanitation, in particular to a centrifugal fan and a road sweeper equipped with the centrifugal fan. Background technique [0002] Existing centrifugal fans are generally figure 1 In the form shown, the air inlet 6 is arranged on the volute 1 along the axial direction of the centrifugal fan, and the air outlet 7 is arranged tangentially to the volute 1 in a direction parallel to the front and rear disks of the volute. Therefore, For the existing centrifugal fans, the air inlet direction and the air outlet direction are vertical, but when the centrifugal fan is used on some specific equipment, this may cause inconvenience, for example, on a road sweeper, the air inlet duct Both the air inlet pipe and the air outlet pipe are set parallel to the front and rear disks of the volute, but since the air inlet 6 is arranged along the axial direction of the volute 1, it is necessary to connect the air inlet pipe to the air ...
