Problems solved by technology

In the current production process, most of the wet dust removal methods are used, so that the dust contains a certain amount of water, so the viscosity is relatively high, and it will stick to the impeller blades of the fan, forming serious dust scaling. When part of the scaling is on the impeller blades After falling off under centrifugal action, it will seriously affect the balance of impeller blades
In addition, the impeller blades are easily out of balance when they are deformed by high temperature, resulting in greater vibration of the fan, increasing noise, and at the same time causing wear and tear on the shaft and bearings that drive the impeller blades to rotate, reducing the service life of the fan

Abstract

The invention discloses a self-balancing fan device. The self-balancing fan device is characterized by comprising a frame, a base, a connecting assembly and a fan. The machine frame comprises three to eight groups of stand column assemblies, every group of stand column assembly comprises a stand column which is vertically arranged along the axis of the group of stand column assembly, and the groups of the stand column assemblies are distributed in the axis of the rotation axis of an impeller in a regular polygonal shape. The base comprises square tubes which are identical to the stand column assemblies in number, the square tubes are fixedly welded end to end to form a polygonal mounting rack corresponding to the regular polygon of the stand column assemblies; connecting assemblies are identical to the stand column assemblies in number. The base is suspended on the frame through the connecting assemblies and detachably, elastic-adjustably and fixedly connected with the frame. The fan comprises a housing, the impeller, a motor and a transmission assembly and is fixedly arranged on the base through the housing, and the housing is provided with an air inlet and an air outlet.

Description

technical field [0001] The invention relates to the field of dust removal, in particular to a self-balancing fan device used in industrial furnaces and dust removal equipment in the milling industry. Background technique [0002] As we all know, during the production process of industrial furnaces, smoke containing carbon monoxide, dust, etc., which is easy to cause environmental pollution, will be generated. The smoke must be treated accordingly before it can be discharged into the atmosphere. In the current production process, most of the wet dust removal methods are used, so that the dust contains a certain amount of water, so the viscosity is relatively high, and it will stick to the impeller blades of the fan, forming serious dust scaling. When part of the scaling is on the impeller blades After falling off under centrifugal action, it will seriously affect the balance of impeller blades. In addition, the impeller blades are easily out of balance when deformed by high ...
