Description
Technical Field
The utility model belongs to the technical field of industrial dust collectors, and particularly relates to a fan-mounted dust collector.
Background
In the industrial process, a large amount of dust and particles are generated, and many harmful substances and tiny particles are contained therein, which poses a threat to the environment and human health. In order to protect the environment and the health of the human body, dust collectors are widely used as an important industrial pollution control device.
The earliest conventional dust collectors operate on the principle that dust-containing air is sucked into the dust collector and filtered to discharge clean air. The conventional dust collector has a disadvantage in that: the blower is positioned at the forefront end, and the dust-containing gas firstly passes through the blower. This design makes large particulate matter easily impinge on the fan impeller, causing the impeller to become damaged or stuck, thereby affecting machine performance. In order to prevent this, the conventional dust collector often needs to provide a mesh-like guard structure at the air inlet, but this may cause large particles to pass through with difficulty, and easily cause clogging. Meanwhile, the traditional dust collector lacks a dust pre-separation device, so that the filtration is easy to block, and the machine performance is affected.
In order to overcome the drawbacks of the conventional dust collectors, cyclone dust collectors have been developed. The cyclone dust collector separates dust and particles by utilizing the centrifugal force of the rotating air flow, and the fan is positioned between the separator and the filter, so that the defects of the traditional dust collector are effectively avoided. However, the conical cavity inside the cyclone dust collector causes the cyclone dust collector to be large in size, heavy in weight and high in cost, and the application range is greatly limited.
