An environment-friendly fan energy-saving device

Abstract

The invention provides an environment-friendly type draught fan energy-saving device. The environment-friendly type draught fan energy-saving device comprises a Roots air blower, wherein the Roots airblower comprises a pump body, a driving shaft, a driven shaft, a rotor, an air inlet and an air outlet; the driving shaft and the driven shaft are connected with the pump body through bearings respectively; the left end and the right end of the driving shaft are located at the outer part of the pump body respectively; the left end of the driven shaft is located at the outer part of the pump body;the rotor is fixedly mounted at the peripheries of the driving shaft and the driven shaft respectively; the air inlet is located at the lower side of the pump body and the air outlet is located at the upper side of the pump body; a base is arranged below the Roots air blower; the base is fixedly connected with the Roots air blower through a plurality of supporting rods; first gears are fixedly mounted at the right ends of the driving shaft and the driven shaft respectively; the first gear at the front side is engaged and matched with the first gear at the rear side; and a motor is arranged atthe right side of the Roots air blower. According to the environment-friendly type draught fan energy-saving device, two sets of power systems are arranged; an electric power system and a wind energypower system can be alternatively used, so that the consumption of electric energy is effectively saved and the device is suitable for regions with relatively great wind in four seasons.

Description

technical field [0001] The invention belongs to the field of fan energy-saving devices, in particular to an environment-friendly fan energy-saving device. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. The fan is widely used in the ventilation and dust removal of factories, mines, tunnels, cooling towers, vehicles, ships and buildings. and cooling, ventilation and induction of boilers and industrial furnaces; cooling and ventilation in air-conditioning equipment and household appliances; drying and selection of grain, wind tunnel wind source and inflation and propulsion of hovercraft, etc. As a pure energy-consuming electrical appliance, the fan needs to consume a large amount of electric energy when it works, which is not in line with the sustainable development of an environment-friendly society. The existing energy-saving fans generally have com...

Problems solved by technology

As a pure energy-consuming electrical appliance, the fan needs to consume a large amount of electric energy when it is working, which is not in line with the sustainable development of an environment-friendly society. The existing energy-saving fans generally have complex structures. The problem of power consumption required for fan operation cannot meet the actual needs, so we invented a new environmentally friendly fan energy-saving device
