Energy-saving and environmental-friendly material conveying fan

Abstract

The invention relates to the technical field of material conveying and discloses an energy-saving and environmental-friendly material conveying fan. The energy-saving and environmental-friendly material conveying fan comprises a bottom plate. Two movable grooves and a limiting groove are formed in the upper surface of the bottom plate. The limiting groove is positioned between the two movable grooves. The inside of the limiting groove is communicated with the lower part of the bottom plate. The top of the inner side wall of each movable groove is fixedly connected with a stopper ring. The bottom of the inner wall of each movable groove is fixedly connected with a first spring. According to the energy-saving and environmental-friendly material conveying fan, second springs play an elastic supporting role on first compression bars and second compression bars to achieve the first shock absorption function; support bars conveniently transmit the pressure of the first compression bars and the second compression bars to the first springs; the first springs play the second shock absorption function on a casing; and a fixed rod compresses the air in the casing by using a sealing block to achieve the third shock absorption function, the influence caused by shaking of the casing is reduced, the role of reducing noise is played and the environmental-friendly effect is achieved.

Description

technical field [0001] The invention relates to the technical field of material conveying, in particular to an energy-saving and environment-friendly material conveying fan. Background technique [0002] The blower is also called a centrifugal fan. The centrifugal fan is a machine that relies on input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induction of boilers and industrial furnaces; cooling and cooling of air conditioning equipment and household appliances Ventilation; drying and selection of grain; wind tunnel wind source and inflation and propulsion of hovercraft, etc. At present, when most fans are manufactured, the motor with adjustable strength is the first choice. Due to the adjustability of the motor, the fan has a certain energy-saving effe...
