Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] The gist of the present invention is to analyze the problem that the existing centrifugal fan used for fiber conveying tends to cause accumulation during fiber conveying, and to provide a centrifugal fan that can effectively avoid fiber accumulation by improving the centrifugal fan as a whole and the centrifugal fan used in the centrifugal fan. A centrifugal fan and a fan provided with the centrifugal fan.

[0022] see figure 1 , similar to the existing centrifugal fan, the centrifugal fan of the present invention also includes a volute 13, the centrifugal fan 15 is arranged in the volute 13, and the centrifugal fan 15 is directly driven by the motor 11 or indirectly through a transmission mechanism. In this embodiment The centrifugal fan 15 is d...

Abstract

The invention aims at the defect that existing centrifugal blowers for conveying fibers are easy to cause aggregation during fiber conveying to provide a centrifugal fan capable of effectively avoiding fiber aggregation and a centrifugal blower with the centrifugal fan. The centrifugal fan comprises a plate, main blades are arranged on a downwind side of the plate, auxiliary blades are arranged on a leeward side of the plate, the auxiliary blades are shorter than the main blades and in one-to-one correspondence with the main blades, and a vent hole is arranged between each two main blades on the periphery of the axis of the plate. The centrifugal blower is compact in structure and powerful in suction, fiber aggregation during fiber conveying and rotary shaft jamming caused by excessive fiber aggregation can be avoided while fiber conveying efficiency is improved, and accordingly normal operation time of the fiber conveying centrifugal blower is greatly prolonged, the defect of frequent maintenance of the centrifugal blower is avoided, and operating efficiency of the centrifugal blower is improved.

Description

technical field [0001] The present invention relates to the technical field of a centrifugal fan, in particular to a centrifugal fan capable of avoiding fiber accumulation and a centrifugal fan equipped with the centrifugal fan, which is used to avoid fiber accumulation when conveying fiber materials. Background technique [0002] Fiber conveying fans are widely used in factories to convey the mixture of fibers, wood chips, tobacco, etc. and air. The general fiber conveying fan is a single-suction centrifugal fan, the structure includes a volute, a centrifugal fan located inside the volute, and a motor located outside the volute for driving the centrifugal fan. The fan is connected, and the volute is also provided with an air inlet and an air outlet communicating with the outside world. At present, there are not many types of fans specially used for conveying fibers in China. In some material conveying occasions, dust removal fans are often used instead. As a resul...
