Problems solved by technology
The low-temperature gas is generally discharged directly or after harmless treatment. In the existing gas transportation system, generally high-temperature gas and low-temperature gas need at least two sets of fan systems. One fan system is used for high-temperature gas transportation and recovery, and the other Fan system is used for direct discharge of low temperature gas, high manufacturing and cost

The invention discloses a fan for automatically switching the air outlet according to the temperature, which comprises a volute, the volute is provided with an air inlet channel and an air outlet channel, the fan also includes a bracket, and the bracket is provided with a hollow support seat and its outer fixing The ring, the air inlet channel is rotatably set on the support seat, the motor-driven shaft is set between the bracket and the inner top wall of the volute, the centrifugal fan blade is set on the shaft, and the low-temperature air outlet and high-temperature air outlet are set on the fixed ring. The inner wall of the fixed ring is provided with a circular slideway, the outer end of the air outlet channel matches the circular slideway, and the outer end of the air outlet channel is provided with two electromagnetic telescopic rods with different heights which are respectively controlled by a temperature control switch. The switches are all arranged in the volute, the opening temperature of the normally closed temperature control switch is the same as the closing temperature of the normally open temperature control switch, and the fixing ring is provided with a first positioning hole and a second positioning hole. This blower can automatically switch to the high-temperature gas recovery channel or the low-temperature gas discharge channel according to the gas temperature.
Description
technical field [0001] The invention belongs to the technical field of fans, in particular to a fan that automatically switches air outlets according to temperature. 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. 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 ventilation in air conditioning equipment and household appliances ; Grain drying and selection, wind tunnel wind source and inflation and propulsion of hovercraft, etc. [0003] With the gradual improvement of people's awareness of energy saving and emission reduction, in the existing technology, the heat energy of high-temperature steam and flue gas generated in factories is often recovered and recycled to production. The low-...
